Problems solved by technology
[0003] A common drug injection pump is composed of a drive device and an infusion device. The infusion tube is in the middle of the two devices. The infusion device is locked by the lock in the drive device, thereby compressing the infusion tube. The compression state of the lock and The flatness of the two surfaces clamping the infusion tube is the key factor determining the accuracy of the infusion. Therefore, the structure and processing method of the lock and the pressing surface of the infusion device are relatively high, but the existing production and processing technology is difficult to meet. Therefore, the accuracy of the injection pump infusion accuracy will be difficult to control

The invention discloses a self-locking device of an infusion tube. The self-locking device comprises a fixing unit and a medicine box unit, the medicine box unit is detachably connected with the fixing unit, the fixing unit comprises a fixing seat, a limiting mechanism and a resetting mechanism, the limiting mechanism and the resetting mechanism are both installed on the fixing seat, and a limiting channel is formed between the limiting mechanism and the fixing seat through the resetting mechanism; the medicine box unit comprises a shell and a liquid medicine container with a catheter, an installation groove and an accommodating groove are formed in the shell, the liquid medicine container is detachably installed in the accommodating groove, the installation groove communicates with the exterior of the shell, the catheter extends through the installation groove to the exterior of the shell, a guiding structure is formed on the inner wall of the installation groove, and when the guidingstructure is matched with the limiting mechanism, the limiting channel can be opened so that the catheter can enter or leave the limiting channel. According to the self-locking device of the infusiontube, the structure is simple, disassembly and assembly are convenient, stability and the strength of catheter fixation are high, the manufacturing difficulty is low, the precision of infusion is controlled by an infusion pump, the influence factors of the infusion precision are reduced.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a self-locking device for an infusion tube. Background technique [0002] At present, automatic drug injection pumps are mainly used in places such as postoperative surgery, tumor chemotherapy, painless childbirth, etc., which require relatively high drug intake. Therefore, the infusion accuracy and stability of drug injection pumps determine product quality. an important factor. [0003] A common drug injection pump is composed of a driving device and an infusion device. The infusion tube is in the middle of the two devices. The infusion device is locked by the lock in the drive device, thereby compressing the infusion tube. The compression state of the lock and The flatness of the two surfaces clamping the infusion tube is the key factor determining the accuracy of the infusion. Therefore, the structure and processing method of the lock and the pressing surface of ...
