Postoperative sutureless fixing type negative pressure drainage device

Abstract

The invention belongs to the technical field of medical apparatus preparation, and relates to a postoperative sutureless fixing type negative pressure drainage device. The device comprises a lower enddrainage opening, a scale mark, an upper end drainage pipe thread, an upper end drainage pipe, a fixing plaster application, a fixing plaster application internal thread, a drainage ball, a connecting pipe, a fixing clip, a drainage ball scale mark, a dumping opening, a dumping opening bottle plug, a puncture needle and a lower end drainage pipe. The external threads are installed at one end, connected to the lower end drainage pipe, of the pipe wall of the upper end drainage pipe; an internal thread structure is installed on the fixing plaster application; one end of the upper end drainage pipe and the drainage ball are in sleeved connection and form an integrated structure, and form a drainage device main body with the fixing plaster application and the lower end drainage pipe; the drainage ball is of an oval spherical structure, a hollow connecting pipe is installed at one end of the drainage ball, and the drainage ball is communicated with the upper end drainage pipe through the connecting pipe; a fixing belt is installed on the drainage ball, the fixing clip is installed at the tail end of the fixing belt, and the dumping opening is formed in the drainage ball. The device provides a measurement tool, the coverage is rigorous, the operation is convenient, and the application environment is friendly.

Description

Technical field: [0001] The invention belongs to the technical field of medical device preparation, and relates to a suture-free fixed negative pressure drainage device after an operation, in particular to a suture-free fixed negative pressure drainage tube used after a surgical operation. Background technique: [0002] In clinical practice, negative pressure drainage has a wide range of applications. For the surgical area and subcutaneous area after surgery, a negative pressure drainage tube needs to be placed for drainage. At present, the general catheterization method is to make a small incision or the original incision next to the operation area and insert a drainage tube; The required procedure places the catheter in the defined area. In order to prevent the drainage tube from falling off accidentally, in the prior art, a common fixing method is adopted to fix the drainage tube with skin sutures, and a sterile auxiliary material is pasted outside to cover the incision....

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and propose to design a suture-free fixed negative pressure drainage device after surgery, to overcome the defects that the skin front line fixation method is easy to fail and cause pain to the patient, and to solve the problem of pasting and fixing auxiliary materials to cover the incision The problem of not being strict and prone to infection can solve the problem of inaccurate visual determination of signs and size parameters during surgery, and avoid the phenomenon that the cross-section of the drainage tube lumen is large and easy to inhale large pieces of normal tissue, resulting in drainage tube blockage and normal tissue necrosis.
