Embodiment Construction

[0045] As mentioned above, the existing infusion device is prone to drug blockage during use, and the drug cannot be infused into the body in time, and air will enter the subcutaneous area, affecting the health of the user and posing a safety hazard.

[0046] After research, it was found that the reason for the above problems was that the driving force of the infusion drug was the resilience of the elastic part, but the resilience was prone to change and the stability was uncontrollable, and there was air in the infusion needle when it was inserted into the subcutaneous area.

[0047]In order to solve this problem, the present invention provides a unilaterally driven patch-type drug infusion device. The power unit outputs a controllable driving force to drive the driving part forward, and then pushes the driving gear teeth forward. The power is controllable, and the infusion device Drug blockage is not easy to occur. At the same time, when the structure of the infusion needle ...

Abstract

The invention discloses a unilateral-driven patch type drug infusion device, which comprises an infusion unit including a drug storage unit; a driving wheel rotating to drive the screw to move so as to push a piston arranged in the drug storage unit to advance; at least one driving unit cooperating with the driving wheel, wherein the driving unit includes at least one driving part; a power unit and a reset unit connected to the driving unit; the infusion unit is arranged in a shell; an infusion needle structure which includes a base and an infusion needle fixedly arranged on the base, wherein the base comprises an initial position, a working position and a middle position between the initial position and the working position; and a first clamping portion. The infusion driving force of the infusion device is stable and controllable, and insulin blockage is not prone to occur.

Description

technical field [0001] The invention mainly relates to the field of medical devices, in particular to a unilaterally driven patch type drug infusion device. Background technique [0002] A drug infusion device is a medical device that achieves the purpose of disease treatment by continuously injecting drugs into the patient's body. The drug infusion device is widely used in the treatment of diabetes. It continuously infuses insulin into the patient's skin according to the dose required by the human body, so as to simulate the secretory function of the pancreas, so as to maintain the stability of the patient's blood sugar. The drug fluid is usually stored inside the infusion pump body. In existing drug infusion devices, the pump body is usually pasted directly on the patient's body through medical adhesive tape, and the patient operates the remote device for infusion. [0003] At present, the driving force of existing drug infusion devices is insufficient, and the drug canno...
