Fixed abdominal cavity drainage tube capable of avoiding suture

Abstract

The invention provides a fixed abdominal cavity drainage tube capable of avoiding suture, belongs to the technical field of medical apparatus and instruments, and aims to overcome defects that pain or even tissue necrotic infection can be caused, sutures easily loose or fall off, a drainage tube can be displaced and the like due to the fact that skin can be stretched when a conventional drainage tube is fixed. An airbag is arranged on a drainage tube main body made of soft rubber or a silica gel material; an external fixing device which can be separated from the drainage tube is arranged on a far side of the airbag; a hole through which the drainage tube can penetrate is formed in the external fixing device; the part where the drainage tube is in contact with the external fixing device is narrowed under pressure and can be clamped by the external fixing device. The fixed abdominal cavity drainage tube is capable of preventing a patient from a series of complications caused by suture traction, and is definite and reliable in fixation effect, simple in structure and convenient to use, and applicable to various abdominal surgical operations.

Description

Technical field [0001] The invention relates to a seam-free fixed abdominal drainage tube, which belongs to the technical field of medical devices. Background technique [0002] The abdominal drainage tube currently used clinically is fixed to the human body in a manner similar to the structure of a cable-stayed bridge ( Figure 5 ), that is, one or two stitches are sutured on the skin next to the tube, and then the suture is tied on the drainage tube, so as to prevent the displacement of the drainage tube. However, in this case, the drainage tube often pulls the skin through sutures and causes local obvious pain, especially because many surgeons have never realized the problem due to unskilled techniques, carelessness or pursuit of surgical speed. For various reasons, the sutures were stretched too tightly when tying the knot, which caused unbearable severe pain in some patients, which affected postoperative recovery and quality of life. Long-term stretching will cause ski...
