Embodiment Construction

[0040] 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, which affects the health of the user and poses a safety hazard.

[0041] It has been found through research that the reason for the above problems is that the driving force for the infusion of drugs is the resilience of the elastic component, but the resilience is prone to change and its stability is uncontrollable.

[0042] In order to solve this problem, the present invention provides a unilaterally driven 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, and the power is controllable, so that the infusion device is not easy to produce drug block.

[0043] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the relat...

Abstract

The invention discloses a unilateral driving medicine infusion device which comprises: a medicine storage unit, the medicine storage unit comprising a medicine outlet; a piston and a driving wheel with wheel teeth, which are respectively connected with a screw rod, the driving wheel driving the screw rod to move by rotating so as to push the piston arranged in the medicine storage unit to move forwards; at least one driving unit matched with the driving wheel to operate, the driving unit comprising at least one driving part; a power unit and a reset unit which are connected with the driving unit; and an infusion tube, the infusion tube being a medicine infusion passage, the infusion tube comprising a connecting end and a subcutaneous end, wherein when the connecting end is communicated with the medicine outlet and the subcutaneous end enters a subcutaneous part, medicine can be infused into the subcutaneous part through the infusion tube. The infusion device disclosed by the inventionis difficult to generate medicine blockage.

Description

technical field [0001] The invention mainly relates to the field of medical devices, in particular to a unilaterally driven 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 existing infusion device is prone to drug blockage during use, and the drug cannot be infused ...
