Catheter fixing device for gastrointestinal surgery

Abstract

The invention discloses a catheter fixing device for gastrointestinal surgery, and relates to the technical field of medical instruments. The device comprises a mounting pipe; a conical spring is fixedly connected to one end surface of the mounting pipe; a first sleeve is fixedly connected to one end of the conical spring; a cylinder is fixedly connected in the inner wall of the mounting pipe through connecting rods; the cylinder is positioned at the axial center of the mounting pipe; two telescopic rods are symmetrically and fixedly connected to the circumferential side surface of the cylinder; an arc-shaped plate is fixedly connected to one end of each telescopic rod; and a buffer spring sleeves the circumferential side surface of each telescopic rod. According to the invention, throughthe design of the conical spring, the first sleeve, the cylinder, the telescopic rods, the arc plates, the buffer springs and a second sleeve, the buffer springs and the conical spring are matched toslow down axial movement of the catheter. The structure is simple, the use is convenient, and the problem that recovery of the patient is delayed due to the fact that existing drainage catheters are generally stuck on the skin of a patient by using adhesive tapes and the adhesive tapes fall off easily during turning over and moving of the patient is solved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a catheter fixing device for gastrointestinal surgery. Background technique [0002] After gastrointestinal surgery, it is necessary to insert a drainage catheter in the patient's body to drain the fluid in the patient's body, and the process of draining the fluid takes a long time. [0003] Existing drainage catheters are generally pasted on the patient's skin with tape, but some patients are allergic to the pasted tape, and the pasted tape is easy to fall off when the patient turns over and moves, which delays the recovery of the patient. Contents of the invention [0004] The object of the present invention is to provide a catheter fixing device for gastrointestinal surgery, through the design of the conical spring, the first sleeve, the cylinder, the telescopic rod, the arc plate, the buffer spring and the second sleeve, the existing The drainage catheter is us...
