Problems solved by technology
[0002] In the related art, the chemotherapy pump generally includes two parts, the pump body and the drug box. The pump body and the drug box are usually locked with a knob lock, and the locking strength of the buckle is not strong. It may be loose when it is not installed in place, and Complex disassembly
Moreover, the liquid medicine in the medicine box is usually liquid. When in use, the medicine liquid may enter the pump body and cause the whole chemotherapy pump to not work normally.
In addition, the pressure detection, air bubble detection, infusion speed detection and three-way valve installation and detection mechanism of the chemotherapy pump occupy a large space, which makes the entire chemotherapy pump occupy a large space.
In addition, the manufacturing process of the entire chemotherapy pump is complicated, and the overall structure is complex

The invention discloses a chemotherapy pump, comprising: a pump body and a drug box, wherein one of the drug box and the pump body is provided with at least one fitting slot and lock catches capable of moving between a locking position and an unlocking position, the other of the drug box and the pump body is provided with at least one fitting part suitable for extending into the fitting groove tobe fitted; one of each lock catch and each fitting part is provided with a locking slot, the other of each lock catch and each fitting part is provided with a locking part; when each lock catch is positioned at the locking position, each fitting part is fitted in each fitting slot and each locking part is fitted in each locking slot, and when the lock catch is positioned at the unlocking position,the fitting part is fitted in the fitting slot and the locking part is fitted in the locking slot; and when the lock catch is positioned in the unlocking position, the locking part is detached from the locking slot so that the fitting part is suitable for removing from the fitting slot. According to the chemotherapy pump, a reliable connection between the pump body and the drug box can be realized, and the chemotherapy pump is high in connection strength and convenient to disassemble and assemble.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to a chemotherapy pump. Background technique [0002] In the related art, the chemotherapy pump generally includes two parts: the pump body and the drug box. The pump body and the drug box are usually locked with a knob lock, and the locking strength of the buckle is not strong. Disassembly and assembly are complicated. Moreover, the medicinal solution that is usually liquid in the medicine box may enter the pump body during use, causing the entire chemotherapy pump to fail to work normally. In addition, the pressure detection, air bubble detection, infusion speed detection and three-way valve installation and detection mechanism of the chemotherapy pump occupy a large space, so that the entire chemotherapy pump occupies a large space. In addition, the manufacturing process of the entire chemotherapy pump is complicated, and the overall structure is complicated. Contents of the...
