Technical Field
[0001] The utility model relates to the technical field of electronic drug injection pumps, in particular to an electronic drug injection pump infusion device which can prevent drug liquid from flowing by itself. Background Art
[0002] An electronic infusion pump is a medical device, also known as a medical electronic infusion pump or analgesia pump. Its function is to stably and continuously infuse drugs into the patient's body to achieve therapeutic effects such as continuous analgesia. The electronic infusion pump can set the precise dosage according to clinical needs and achieve continuous micro-infusion, effectively controlling the flow rate and dosage of the drug to ensure that the drug is safely and effectively infused into the patient's body.
[0003] Publication No. CN220090124U discloses an electronic drug injection pump infusion device for preventing drug liquid from flowing freely. The device comprises an infusion device housing and a slider. An infusion tube is mounted on the bottom of the infusion device housing near the infusion bag. A mounting slot is formed on the top side of the infusion device housing. The slider is made of an elastic material and mounted within the mounting slot. A first top buckle is provided on the top outer side of the slider, which abuts against the infusion device housing. A second top buckle is provided on the middle inner side of the slider, which is slidably connected to the infusion device housing. An elastic plate is provided on the bottom outer side of the slider, which abuts against the infusion device housing. A top plate is provided on the bottom inner side of the slider, which abuts against the infusion tube. The anti-self-flow infusion device relies solely on the elastic properties of the slider to achieve the anti-self-flow effect. It has high controllability, a simple structure, and is easy to assemble. The anti-self-flow infusion device has a negligible effect on infusion accuracy and has no special requirements for the infusion pressure of the drive device. The overall assembly is simple and cost-effective, making it very suitable for mass production.
[0004] However, the above device still has shortcomings. Although the elasticity of the slider is used to achieve the effect of preventing self-flow, the entire liquid medicine will still remain in the device, affecting the accuracy of the secondary metered injection, especially for the injection of analgesics and other painkillers, which require relatively high precision.
