Problems solved by technology
During use, when the medicine box device falls off from the driving device, it will cause the liquid medicine to flow into the human body uncontrollably, or the blood will flow back into the infusion tube. This phenomenon can be called the self-flow of the medicine liquid, which will make the patient in great danger

The invention belongs to the technical field of a medicine box device of a medicine injection pump, and particularly relates to an automatic locking mechanism for liquids, and a medicine injection pump comprising the automatic locking mechanism. The automatic locking mechanism for liquids comprises the medicine box device, wherein the medicine box device also comprises a front cover, a rear cover,a movable element, a liquid stopping clip and a transfusion pipe, wherein the rear cover and the front cover are adaptive; one end of the movable element is adaptive to and is movably connected withthe first groove; one end of the liquid stopping clip is adaptive to and is fixedly connected with a second groove; the other end of the liquid stopping clip is adaptive to the other end of the movable element; one side of the transfusion pipe is abutted against a compression rod; the other side of the transfusion pipe is abutted against the outer parts of the first groove and the second groove; and according to different cooperation states of the movable element and the liquid stopping clip and different cooperation states of the medicine box device and the driving device, the connection anddisconnection state of the transfusion pipe can be controlled. The automatic locking mechanism for liquids in the technical scheme is used, when the movable element and the liquid stopping clip are separated and the medicine box device and the driving device are separated, the transfusion pipe is under a disconnection state, and therefore, a purpose of locking the transfusion pipe is realized.
Description
technical field [0001] The invention belongs to the technical field of medicine box devices for injection pumps, and in particular relates to a liquid automatic locking mechanism and a medicine injection pump with the same. Background technique [0002] At present, injection pumps are mainly used in medical places such as postoperative pain, tumor chemotherapy, and painless childbirth. A common drug injection pump consists of two parts: a driving device and a drug box device. The medicine box device and the driving device are fixed together through the connecting mechanism, keeping a specific distance. The medicine box device carries the liquid medicine that needs to be infused, and the driving device controls the moving parts to make periodic movements, and crushes the infusion tube of the medicine box device to realize periodic automatic infusion. During use, when the medicine box device falls off from the driving device, it will cause the liquid medicine to flow into th...
