Large Volume Wearable Injectors

Large volume wearable injectors are medical devices used to deliver high volume of drugs usually in the range of 2-50 ml of drug within 2-15 minutes. As a result, medical device industry has come up with several wearable injectors suitable for the delivery of such molecules. These injectors offer numerous dosing options (continuous, bolus, or basal), integrated safety mechanisms, along with no or minimal risk of needlestick injuries. They have become a preferred choice for administration of drugs in home-care setting and can be used for the subcutaneous drug delivery.

Ultra large volume wearable injectors are used to deliver large volume of drugs. They are designed to deliver the drugs subcutaneously over an extended period of time. Such injectors have the drug solution reservoir with a capacity of 2ml or more. Large volume injectors are commonly used for rapid administration of biologic drug formulations, mainly those contain monoclonal antibodies as the biologic formulation is viscous at high concentration. Biologics have high viscosity and cannot be administered in lower volume, and thus delivered by large volume injectors.

Variants of these wearable devices have been designed to administer highly viscous drugs (such as biologics) in large volumes (more than 1 mL), offering numerous dosing options. Large volume injectors offer a solution to patients suffering from both chronic and non-communicable diseases. They can be used for continuous dosing and bolus dosing. Some of the features of these devices include error alerts, visual/aid drug delivery confirmation notifications, and connectivity to web-based portals. These features help increase patient compliance and reduce pain.

Large volume wearable injectors are often used in the treatment of chronic diseases, such as cancer, diabetes, and autoimmune disorders. Chronic diseases are a public health emergency in Mexico, and chronic diseases are primary cause of death worldwide, leading to more deaths annually than all other causes combined. Thus, with the increase in burden of aforementioned diseases, the usage of large volume injectors is also increasing rapidly.
