Technical Field

[0001] The utility model relates to the technical field of infusion pump liquid stop, in particular to an infusion pump provided with a liquid limiting clip with a groove. Background Art

[0002] Medical infusion pumps can achieve the following functional characteristics during the treatment process: (1) accurately measure and control the infusion speed; (2) accurately measure and control the infusion volume; (3) alarm for abnormal conditions such as air bubbles, empty liquid, liquid leakage, and infusion tube blockage, and automatically cut off the infusion path; (4) color OLED display; (5) achieve intelligent control of infusion. An infusion pump is a medical instrument that can operate and control the drip speed and time according to the wishes of nurses when powered on. In the research and development of biopharmaceuticals and in the chemical industry, such as in the configuration of test tube droppers and some liquid drugs that need to be configured strictly according to a certain ratio, it is easy to cause human configuration errors, and it is also very difficult to grasp the component ratio of the drugs. Therefore, an instrument that can accurately measure the output liquid is needed. The functions of the infusion pump solve some basic problems existing in current clinical medicine and have certain potential market value.

[0003] Currently, in the technical field of infusion pump liquid stop, the flow of liquid drugs in the infusion pump is mainly restricted by the manual push of nurses.

Reduce the force when the nurse stops pushing; 2. The structural design of the liquid stop device has low matching accuracy and low efficiency in restricting liquid flow.
