Problems solved by technology

In some applications, the drug delivery rate is usually calculated in tens of minutes, hours or even days, and those reported portable devices cannot achieve such a long drug delivery time
[0017] Many existing drug delivery systems still have deficiencies, so it is necessary to provide a minimally invasive, self-powered, low-cost, simple and flexible, easy to operate and control, and sustainable drug delivery device

Abstract

The invention relates to a disposable patch-type drug administration device with own power, which comprises a microneedle, a drug storage chamber, a pressure chamber, an activation device and a piston, wherein the drug storage chamber contains a drug for infusion, and a liquid channel is arranged between the drug storage chamber and the microneedle; a pressure device in the pressure chamber hydraulically or directly acts on the drug storage chamber, and the activation device is used for starting a pressure exerting device in the pressure chamber; and the piston is usually positioned in the drug storage chamber, unidirectionally moves as the pressure increases, and separates the drug liquid in the pressure chamber from the drug liquid in the drug storage chamber. The invention simultaneously relates to a shell of the drug administration device and a use method thereof.

Description

technical field [0001] The present invention relates to a drug delivery device and a method of use thereof. Specifically, the device is a single-use drug delivery device with its own power. The device can effectively control the administration rate and prolong the administration time. Background technique [0002] Injection is the most reliable route of administration. For many macromolecular drugs, injection is usually the only route of administration. However, injection administration faces a series of problems such as the need for professional training, patient fear, safety, and cross-infection. Therefore, changing the route of administration is a research area that has attracted extensive attention. [0003] Microneedle is a transdermal mechanical device that can only penetrate the stratum corneum to form a drug delivery channel without stimulating the subcutaneous pain nerve [1-2]. Microneedle injection, or microneedle fusion, is a minimally invasive route of drug de...
