The wearable injector devices are entirely based on an osmotic drive engine that is specially designed for the patients at home as an easy-to-use and prefilled auto-injector. The Worldwide Wearable Injectors Market share summed up to be around USD 5.49 billion, and the forecast suggests that by 2030, it would pile up to USD 17.76 billion, with an overall CAGR of 12.46%. This device contains a few parts & no electronics, thereby resulting in low production cost, and is designed efficiently as a prefilled disposable injector so that it requires no more assembly steps by the patient. Furthermore, this device contains a high force capacity & can inject some high viscosity pharmaceuticals at a much lower flow rate. Designed for the purpose of a standard 3ml drug cartridge, it is the first version of the device that allows the usage of standard filling lines, with no such risk of drug stability introduced by the device. This concept is highly flexible, & a design for up to a level of 10ml of the drug is highly configurable.

Osmosis (One of the most powerful drive systems)

Water & salt constitutes the device engine as opposed to the conventional drive mechanisms using either motors or batteries, or springs. Salt is released on one side of the semi-permeable membrane as soon as the device gets activated. An excess amount of clean water, then drawn into the salt side, handsomely drives the rubber stopper in some standard drug cartridges. The current configuration delivers it at a flow rate of nearly 1ml/min. However, the osmosis process can slowly build up the high pressure, whereby the user of the device user can inject high viscosity drugs by means of thin needles, the contrary to a spring-based system that instantly excels out the full energy.

The various types of Patient-friendly intuitive injection devices

The device is prefilled with a high-quality drug & it is to be kept refrigerated in the 3ml configuration, and the device housing is around 76mm (or 3 inches) long. Whenever the user installs the device into the body, the needle is automatically inserted into the skin by means of the push of a button. When held in hand, it should be rotated in an anticlockwise direction perpendicularly. This device is noiseless during the injection process. Upon completion, the needle is withdrawn, & hence the user can remove & discard it.

The Cost-effectiveness of the wearable injectors

The overall part count in the device is low, thus allowing for a lower price. The manufacturing cost is also on the line, along with the cost of a standard single-used and prefilled auto-injector. This 3ml device is widely used for the regulatory development of combination products. The device can also be configured to a limit of up to 10ml cartridges by using the same basic technology in a customized design. The Regulatory development & manufacturing of these new wearable injector devices will be in a joint collaboration with the global well-reputed CDMO (contract manufacturing organisations).


Hence, the advent of these high-technology wearable injector devices is expected to change the market outlook entirely in the years to come.
