Therapeutic apparatus for postoperative venous crisis of severed finger replantation

Abstract

The invention discloses a therapeutic apparatus for postoperative venous crisis of severed finger replantation. The therapeutic apparatus comprises an electromagnetic valve, a timing switch, a connecting tube, a dropping bottle and a universal needle, wherein one end of the electromagnetic valve is connected with the timing switch through a connecting line, and the timing switch is externally connected with a power supply; the other end of the electromagnetic valve is connected with the connecting tube, one end of the connecting tube is connected with the dropping bottle which is located above the electromagnetic valve, the other end of the connecting tube is connected with the universal needle, and the universal needle is inserted into an incision of a replanted finger body. According to the therapeutic apparatus, a rinsing needle is arranged in the incision and has the function of a drainage tube; repeated injuries of local tissue due to the fact the incision is required to be opened by a sterile needle repeatedly because of closing of the incision are avoided; the needle cannot fall with finger position change and is more reliable when compared with manpower, great work pressure of a nurse is reduced, and the probability of secondary pollution of the incision is reduced; the bloodletting speed can be increased or decreased through adjustment of rinsing speed and frequency, and accordingly, illness needs are met.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a device for treating venous crisis after severed finger replantation. Background technique [0002] For cases with severe preoperative venous damage and cases with multiple recurrences after exploration, the current mainstream and conventional method refers to side-to-side incision and hemorrhage therapy, which is beneficial to reduce the pressure in the local venous system of the severed finger, and at the same time It also relieves the tension of the peripheral capillaries so that the tissues can get sufficient blood supply. When using this method to perform bloodletting treatment on replanted fingers with venous crisis, it is found that the current method of wet compress with heparin cotton balls in order to maintain incision bleeding has many disadvantages. [0003] 1. The incision is easy to close after being blocked. It needs to be incised multiple times with a sterile needle...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a device for treating venous crisis after severed finger replantation, which solves the defects of the prior art and effectively overcomes the failure of the treatment caused by the cotton ball falling off due to the change of the position of the finger when the patient is asleep. Replacing heparin cotton balls relies too much on manpower, the speed of cotton ball bloodletting therapy is uncontrollable, and the curative effect is inaccurate.
