Our Dry Powder Inhaler is ready for your application

8/16/17     DoseOne, LLC holds multiple patents and prepared to partner the most innovative DPIs available today, the DoseOne™ Single Dose Powder Inhaler.

Below is an article in FiercePharma about the dry powder inhaler we have blogged about in the past.

Development of the DoseOne™ single dose powder inhaler (US Patents #7,832,399 B2 and #8,360,057 B2) required a multi-disciplinary team approach, as any such drug delivery device needs to combine not just design skills, but also software and mechanical engineering capabilities, and expertise in analytical science and industrialization. From concept to creation, the DoseOne™ device was designed to be sympathetic to the requirements for mass manufacture and regulatory compliance.

The two patents associated with the DoseOne™ single dose powder inhaler cover the unique dosing mechanism of the device, and the ability to use the technology for dual-drug delivery. The DoseOne™ inhaler contains multiple, segregated air pathways, which keeps powder hold-up to a minimum, and makes device optimization for powder properties considerably easier. Using this technology which drives the DoseOne™ inhaler, designs have been developed and patented for dual drug delivery, the device allowing for simultaneous release of two different and separately contained drugs.

From a manufacturability point of view, the key advantage of the DoseOne™ is its simplicity and intuitive use (one motion and complete). Through the expeditious use of design and micro manufacturing expertise, DoseOne™ is an easy to manufacture and assemble 3-component device. The simplicity is of great importance as an inexpensive drug delivery option, costing $0.16 per device at full volume. The ultra-precise nature of the design and components also ensures that the device is small, which makes it easy to carry and package for mass drug distribution.

The inherent characteristics, size, and nature of the drug delivery technology make the DoseOne™ inhaler hugely advantageous for numerous end use applications. One obvious area of interest is in third world treatments of pandemics and epidemics, where there is an enormous emphasis on safety of drug delivery, simplicity of drug delivery, and ways to show compliance with dose administered. The DoseOne™ is equipped with a simple dose readiness indicator and a dose delivery indicator, and its size and ease of use (relying on patient inhalation rather than propellant technologies) make it well suited to environments where local health services are sub-optimal. In addition, for mass drug administration the low unit cost of the device is obviously hugely significant.

The DoseOne™ is extremely easy to validate, and is ideal for drop-shipping with all this implies in reduction of total inventory management and shipping costs, which can reduce the end use cost of the device.

The simplicity of the design also makes it easy to revise to accommodate specific formulations. Of especial importance, however, is the ability using the DoseOne™ inhaler to simultaneously pierce capsules containing different drugs, meaning that the drugs mix within the body, so there is no necessity to address drug interaction issues as would be the case if the drugs were mixed in one capsule.

DoseOne™ is a perfect example of what can be achieved if an innate understanding of micro manufacturing design and manufacturing is combined with an understanding of the regulatory environment that exists around drug delivery devices these days, and a realization of the potential for innovative solutions that cater for mass “self” administration of drugs in a cost-effective and safe way.

The Market for DPIs.
Powder inhalers deliver drugs in the form of dry powder directly to the lungs, and are typically used in the treatment of respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD), asthma, and emphysema. However, due to many of their innate characteristics and advantages as a drug delivery mechanism, there is burgeoning interest around the use of dry powder inhalers (DPIs) in the pharmaceutical and medical device sectors.
In many ways, DPIs have become more prevalent as they have been tailored for markets previously catered for by Metered Dose Inhalers (MDIs), which many patients find difficult to use, which rely on propellants that have come under more and more legislative scrutiny, and — from the device manufacturers and pharmaceutical company’s perspective — are often expensive to make. It is generally agreed that DPIs are easier to use as they simply rely on patient inspiration to deliver the drug, and are less likely to lead to side-effects such as irritation of the airways.

As with all families of drug delivery devices, the balance for drug companies is between affordability and functionality. Unit cost per device is obviously critical, as is the ability for the drug to be delivered in the correct dose, and for there to be minimum drug wastage.

The DoseOne™ Solution
DoseOne™ is a single-use disposable DPI, and as such overcomes many of the problems associated with multi-use DPIs and MDIs. As a single dose device, for example, it minimizes dose-to-dose consistency risk, and also negates the requirement for priming needed by many devices, with all this implies in respect of drug wastage.

In addition, as DoseOne™ is a single use disposable device — and therefore a new device is used for each dose — it eliminates the frequent problem of powder caking and flaking which can affect dose volumes in multi-dose devices.

Also, as a single use device, the issue of, and problems associated with, dose counting — which preoccupies the FDA and other health organizations around the world — is made redundant. In its current state, DoseOne™ contains a simple dose readiness indicator as well as a dose delivery indicator in the form of a viewing window, therefore promoting patient compliance by confirming the dose is ready and has been completely administered.

As such, DoseOne™ satisfies the regulatory demands previously only achieved by complicated and expensive designs. So for any pharma or device manufacturer looking to locate a novel, cost-effective, and efficient drug delivery option please call or email Donna Bibber at dbibber@doseone.com to discuss potential partnerships.

The Merging of Medical Device and Pharmaceutical Industries

7/27/17     As product technology advances and the general demand for healthcare expands, the industry line between medical device manufacturers and pharmaceutical companies are being blurred as innovative products continue to emerge. Manufacturers are exploring new technologies that adhere to better patient compliance, improve product safety and utilize unique drug delivery methods.

These new technologies include:
–  Small adhesive patches that are encapsulated and swallowed. Once in the body they dissolve and stick to the wall of the intestine to deliver time released    medication
– Implantable devices that automatically run tests and dose medications
– Transdermal patches that are embedded with micro sized needles that deliver medication over a period of time

As technology advances and healthcare treatments become more complex, the pharmaceutical and medical device industries will continue to merge their technologies and expertise to deliver patient solutions that combine both pharmaceuticals and medical devices into one simple and convenient product. Currently about half of all manufacturers in both industries have turned to contract services to meet demand as products become more intertwined.

As this newly meshed relationship forms there are many concerns and factors that both industries need to keep in mind, with the top two being:
1. Regulations: Government regulation requires manufacturers to adapt their processes to meet changing production demands of speed, flexibility, and safety while continuing to comply with regulations. Complying with these regulations usually requires a large investment in machinery and software systems, with two out of three companies reporting that they will be spending more on capital equipment in the next two years. Smaller manufacturers are having a hard time with this large expenditure burden, so they are turning to OEMs to help with regulation compliance strategies by adapting their machines to meet data acquisition and storage requirements for marking and tracking products which includes coding and vision inspection systems.
2. High Demand: In addition to complying with numerous regulations, pharmaceutical and medical device manufacturers also face the challenge of increasing consumer demand. This demand is fueled by increased insurance coverage rates and improved healthcare availability. To meet this demand, manufacturers have to produce products at a faster rate, while adhering to stringent regulations. As a result, many manufacturers have turned to smaller batch runs with greater product diversity and more frequent changeovers, requiring machines that are both fast and versatile. OEMs can be a valuable partner in adjusting to process changes by providing manufacturers with innovative, flexible machine builds that are designed to integrate seamlessly into production lines and software systems.

Manufacturers Need a Partner – As pharmaceutical and medical device companies strive to keep up with market demand, they will search for trusted partners to help them comply with the maze of complex regulations. Manufacturers will also need help with the process of implementing new technology, especially automation and data management solutions, which will play a crucial role in a manufacturer’s ability to operate efficiently in a growing market. OEMs and technology suppliers are perfectly situated to offer their experience and expertise to manufacturers as an invaluable tool in resolving future challenges; expertise in automation, integration services, and regulation compliance are key. OEMs and technology suppliers can form stronger relationships by working collaboratively to address a manufacturer’s unique needs on an individual level, in order to achieve a mutually beneficial partnership.

Removing the “patient factor” from glaucoma treatment

7/20/17     Over 3 million Americans suffer with glaucoma and 75% of them administer their own drug treatment incorrectly. These “patient factors” include not being able to see clearly enough to pick up the right medication to use, the inability to successfully put droplets into the eye, and simple forgetfulness.
Sustained delivery devices that take glaucoma therapy out of patients’ hands may be the answer to the many issues related to adherence, with significant benefits for patients and physicians. These technologies are broken into 3 general categories: injectable sustained-release formulations, drug-eluting rings and contact lenses, and punctal plug reservoirs.

glaucoma ring
Drug-eluting rings are currently in clinical trial right now. They are made of a silicone polymer and can house most any drug combination. The ring is put under the eye lid and slowly excretes drug delivery for up to 6 months. This alleviates the patient having to remember to take their medicine. An issue researchers are trying to overcome with rings is they can fall out without the patient being aware of it happening, making it virtually unknown how much of the drug the patient actually received. Once this hurdle is overcome the next obstacle is to figure out the timing of introducing this treatment to a patient. Timing can be a critical factor in the successful treatment of glaucoma. Once the clinical trials are completed and the logistics figured out, drug-eluting rings will most likely play a significant role in glaucoma treatment.

Micro Molder vs. Conventional Molder

7 reasons you need a Micro Molder vs. Conventional Molder

  1. Shot size is less than 30% of barrel capacity
  2. Your tooling source thinks it’s doable but “hasn’t made a mold quite that small before”
  3. Optimized runner systems in comparison to longer runner systems
  4. Your molding source doesn’t have metrology equipment with high resolution
  5. Highly complex detail is achievable with a micro molder
  6. Low tolerance tooling and molding processes
  7. Minimal material waste = money savings

Wearable Micro Component Health Sensors

7/6/17     Wearable sensors combine computers with our bodies. Companies like Google and Apple are focusing on self-health monitoring. We have already been introduced to things like Fitbit which offer wearable fitness trackers that record our footsteps and heart rate. In the near future these health sensors will evolve into items more complex yet smaller in size. The thought of wearing a bulky bracelet to monitor your heart rate will be replaced with adhesive sensors similar to a sticker. They can be worn on the skin and the material makes them bendable and stretchable, like this prototype from MC10 which senses heart rate and other vital signs.

micro component sensor

These breathable, bendable, stretchable devices are, in itself, a hurdle to overcome when designing them. They need to be able to do all of the bending and stretching while keeping all of the micro components inside that make them work from breaking or malfunctioning. Imagine a tiny battery or sensitive sensor being able to move with our skin and nothing inside the component breaks. This is where state of the art technology and novel micro-component expertise come in. Without them, these new technologies wouldn’t exist.

Besides the numerous health benefits and ease of use, wearable health sensors allow patient’s health to be tracked over time, efficiently and without frequent, costly follow up visits to the doctor. This could have a positive impact on healthcare costs. The future of wearable health sensors could help us manage chronic illnesses and chronic pain; they could be an early detection warning of an on-coming illness or episode like a seizure; and they could send daily accurate information to our doctors informing them of things we may not even realize is going on within our bodies.

Micro Component Thumbnail Device

Researchers at the MIT have developed a wearable device that turns the user’s thumbnail into a miniature wireless track pad. This would allow users to control wireless devices when their hands are full, like answering the phone while carrying grocery bags.

According to Cindy Hsin-Liu Kao, an MIT graduate student in media arts and sciences and lead author on the new paper, the device was inspired by the colorful stickers that some women apply to their nails. “It’s a cosmetic product, popular in Asian countries,” says Kao, who is Taiwanese. “When I came here, I was looking for them, but I couldn’t find them, so I’d have my family mail them to me.” They can have a thin layered cover with a design on it so it looks like nailpolish.

micro component

A future commercial version of this device would have a detachable membrane on its surface. They used capacitive sensing (the same kind of sensing the iPhone’s touch screen relies on) to register touch. It can tolerate a thin, nonactive layer between the user’s finger and the underlying sensors.

The thumbnail size prototype includes capacitive sensors, a battery, and three separate chips – a microcontroller, a Bluetooth radio chip, and a capacitive-sensing. Due to its small size using micro components, the battery life isn’t very long therefore the device would need to be turned off when not in use.

Micro technology is such an amazing aspect to the electronics and medical industries, imagine not having to carry a cell phone around anymore, you could access it on your thumbnail!!!

Intraocular Micro Components

6/15/17     Cataracts, diabetic retinopathy and glaucoma are major causes of loss of vision. Implants are generally used to help with these situations. Ophthalmic and intraocular implants are largely made up of many micro sized and highly precise components and assemblies.

micro glaucoma drain

This glaucoma drain, commonly known as a shunt, is injection molded, spherically shaped with a wedge-shaped radial side action in the tool that creates the drain geometry.  At the end of the side action travel is a 250 micron orifice whereby no flash can be tolerated.  Shunts are mostly tubular, however this one is 3d shaped and designed for placement in the sclera (side of the eye).  It is designed to act like a venturi system which uses the pressure of the eye to push the discharge from glaucoma to behind the eye where it can drain.  In addition to the 250 micron entry orifice, there are 4 suture holes of 250 micron diameter (2x a human hair) molded into the top of the implant.  These suture holes also must be free and clear of particulate or flash to prevent sutures from cutting during implantable or after surgery. Designing and manufacturing micro sized components like this takes special technology and tooling. To get the job done right you need to find a company that has years of experience in micro components, like Micro Engineering Solutions does. If you have a project that needs micro-specialty please give us a call.

Micro Medical Device takes on the Opiod Crisis

6/8/17     Smart pills are fairly new to the medical field. They do a variety of things from measuring the amount of a substance in your body to acting like a micro-submarine maneuvering throughout your body for a specific purpose.

One of the more recent hopes of this device is to put a dent in the opiod overdose crisis. Imagine a smart pill that could detect and measure other substances in your body, then administer the correct amount of drug to counteract the opiods! This could be possible using microfluidic and micro actuator techniques. Scientists are currently working out the details on this concept and could make a quick positive direct impact in the fight against opiod overdoses.

Micro Devices Drive a $38 Billion Opportunity

5/26/17     Do you remember the movie Fantastic Voyage from 1966 where a submarine crew was shrunk to a micro size and drove around inside of a body to repair brain damage? This technology is no longer the topic of Hollywood fantasies. We are using this cutting edge micro technology today! It’s called Radio Frequency Identification (RFID). It uses tiny transponders, or tags, to find and track objects. Each micro tag has an antenna that transmits and receives radio waves from an RFID transceiver.
Research and Markets estimates that the global market for RFID and related technologies should reach $38 billion by 2021 from $16.2 billion in 2016, for a compound annual growth rate from 2016 to 2021 of 18.6%.
It has been said that “miniaturized, wireless tracking devices for medicine, retail, manufacturing, and a wide range of other industries are one of the hottest investment trends you can find”.
Doctors use RFID sub-dermal implants in patients to monitor their whereabouts, bio-functions and medical history. Pharmaceutical firms use them to track millions of proprietary drug compounds in their product libraries. Laboratories use them to track tissue or fluid samples.
RFID tags also are used in retail stores, at tollbooths, at gas pumps, on automaker factory floors, and in livestock on farms. As Linda points out:

Technology specialists at Breakthrough Tech Profits emphasize that wireless tracking systems such as RFID represent an exploding, multi-year investing bonanza, especially as they are integrated into the Internet of Things:
“By the end of 2020, the installed base of ‘things’ could top 200 billion worldwide, including some 30 billion installed autonomous things, largely driven by intelligent systems that will be collecting data across both enterprise and consumer applications, according to research firm IDC.
All processor-based systems (think handsets, wearables, GPS devices, RFID tags, automobiles, airplanes, medical devices, HVAC controllers and smart meters) continuously generate machine data, both structured and unstructured.”
The growth stock winners of the future will be the companies offering software platforms that enable organizations to gain operational intelligence by sorting through all of this data. As well as companies that specialize in miniaturization devices.
