Infusion pump and infusion equipment

Abstract

The invention discloses an infusion pump and infusion equipment. The infusion pump comprises a main body, a door body and a peristaltic component, wherein the peristaltic component is arranged on the main body and is used for driving liquid inside an infusion tube to move; the door body and the peristaltic component are relatively arranged; the peristaltic component comprises a plurality of peristaltic sheets which are spaced from each other; the door body is provided with a pressing block which is relatively arranged with the peristaltic sheet; a gap for the infusion tube to pass through is formed between each of the peristaltic sheets and the pressing block; each of the peristaltic sheets is provided with a convex rib on the end face facing the pressing block; and when the door body is fastened on the main body, the infusion tube is firmly pressed on the pressing block by virtue of at least one of the convex ribs, so that the liquid in the infusion tube is prevented from flowing. According to the technical scheme, by virtue of the convex ribs which are arranged on the end faces, facing the pressing block, of the peristaltic sheets, the contact areas between the peristaltic sheets and the infusion tube are effectively reduced, so that a squeezing effect on the infusion tube is effectively guaranteed and the occurrence of a liquid leakage phenomenon is avoided; and the service safety of the infusion pump is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion pump and infusion equipment. Background technique [0002] As a precision medical equipment, the infusion pump needs to ensure precise precision control. When the infusion is complete, the infusion pump is turned off. At this time, it is necessary to ensure that the infusion tube is completely cut off to avoid excessive infusion. [0003] The contact area between the peristaltic sheet of the existing infusion pump and the infusion tube is relatively large. Under the premise of a certain pressure in the infusion tube, it is necessary to flatten the infusion tube so that the infusion tube is in a cut-off state. larger. However, as the infusion pump works under high pressure for a long time, the components of the infusion pump (such as the spring of the briquetting block) will be fatigued and deformed without reset under the long-term high pressure, resultin...

AI Technical Summary

Problems solved by technology

However, as the infusion pump works under high pressure for a long time, the components of the infusion pump (such as the spring of the briquetting block) will be fatigued and deformed without reset under the long-term high pressure, resulting in the cut-off of the infusion tube. The pressure cannot be effectively guaranteed, and leakage occurs, which brings safety hazards to patients
