Multi-flow speed controller of analgesia pump

Abstract

Then invention relates to a multi-flow speed controller of an analgesia pump. The multi-flow speed controller of the analgesia pump comprise a speed regulating mechanism, a liquid inlet tube and a liquid outlet tube, wherein the speed regulating mechanism comprises a flow tube and a speed regulating press plate, the speed regulating press plate is movably arranged on one side of the flow tube, and the speed regulating press plate changes the cross sectional area of the flow tube through squeezing the flow tube; the liquid inlet tube is communicated with the flow tube; the liquid outlet tube is communicated with the flow tube. The multi-flow speed controller rotates the speed regulating press plate through a speed regulating key, the flow speed of a silicone tube is changed by changing the length of the speed regulating press plate, the smoothness of the flow tube is guaranteed, lengths of the speed regulating press plate in all directions correspond to the corresponding flow speeds, the lengths and the flow speeds are in inverse correlation with each other, the lengths are subjected to accurate calculation and tests, the flow speeds are more accurate, the controller is safer for patients, and needed analgesia effects can be achieved. The multi-flow speed controller of the analgesia pump has the advantages that the structure is reasonable and simple, and the operation is more simple and convenient for medical staff.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a multi-flow rate controller of an analgesic pump. Background technique [0002] The infusion pump, also known as the analgesic pump, maintains a timely and stable concentration of analgesic drugs in the blood plasma, and allows the patient to press the drug by himself to quickly enhance the effect and make the treatment more individualized. [0003] For a long time, people think that postoperative pain is a natural phenomenon and inevitable, and they can only endure it silently. In fact, pain itself can produce a series of pathophysiological changes, such as the influence of the body's autonomic nervous system, causing heart rate to increase, shortness of breath, and blood pressure to increase; mental changes can lead to restlessness and depression, which in turn affect digestive system functions and physical strength. The recovery of endocrine and hormones directly and indir...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects of the prior art and provide a multi-flow rate controller for an analgesic pump, which solves the problem that the multi-flow rate of the infusion pump in the prior art is mostly a single flow rate, which cannot meet the needs of patients more effectively. The problem of analgesic effect
