Problems solved by technology

[0004] The second is the lack of safety protection, and the phenomenon of blood returning occurs from time to time
[0005] The third is that when the injection pump and the matching liquid bag are installed and used, the clamping is often not in place, or it falls off halfway, which will cause the valve plate of the injection pump to be unable to effectively prevent the liquid in the matching liquid bag from flowing out. When the liquid bag is higher than the human body, the infusion may be out of control due to gravity, resulting in the risk of excessive infusion

Abstract

The invention discloses an infusion bag matched for a safe drug infusion pump. The infusion bag comprises an infusion bag body, a pump pipe and an infusion catheter, wherein the tail end of the infusion catheter is connected with a combined joint which comprises a pressure control unit, a liquid storage device is arranged behind the pressure control unit, and a liquid control unit is arranged behind the liquid storage device and connected with a Luer joint; the pressure control unit comprises an inlet joint which is connected with the infusion catheter, a drainage port is formed in the rear part of the inlet joint and is covered with an elastic piece, and an outlet joint is arranged behind the drainage port; the liquid storage device comprises a liquid storage cavity which is communicated with the outlet joint; the liquid control unit comprises a main drainage port and an auxiliary drainage port on a liquid passage, and a covering part is arranged on the main drainage port and an auxiliary drainage port respectively. The infusion bag matched for the safe drug infusion pump is made from a non-PVC material, the liquid can be stopped automatically and effectively, excessive infusion can be prevented under the effect of gravity, the liquid can be supplied for a certain time after infusion, the effect for preventing blood return can be effectively realized, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of injection pumps in medical devices, in particular to a safe injection pump that does not contain plasticizers, has no or very low adsorption effect on drugs, is not affected by gravity, and can automatically stop liquid and prevent blood return. Liquid bag. Background technique [0002] The injection pump used in the prior art is equipped with a liquid bag (disposable infusion part of the injection pump), which has obvious deficiencies: [0003] One is generally polyvinyl chloride material (PVC) as raw material. Although PVC has the advantages of excellent physical and mechanical properties, low price, and simple production process, in order to improve the plasticity, flexibility, stability, fluidity, mold release and surface smoothness of the material during processing, in the production process Plasticizers such as DEHP and stabilizers containing various heavy metal ions must be added. Various studie...
