Abstract

A drainage tube with a guider comprises a drainage tube, a water sac and a metal guider; the drainage tube is Y-shaped, one end of the drainage tube is positioned in the body, a plurality of side holes are formed in the tube wall of the inner end of the body, and the other two ends of the drainage tube are positioned outside the body and are respectively a drainage port and a water injection port; the drainage tube is of a partial common-tube double-cavity structure consisting of a thick tube and a thin tube, the thick tube and the thin tube are not communicated with each other, the thick tube is communicated with the inner end of the drainage tube and the drainage port, and the thin tube is communicated with the water injection port and the water sac; the water sac is tightly close to the inner side of the body wall, and is wrapped and fixed in the middle of the drainage tube; the metal guider comprises a straight core with a tip end and a handle fixed at the other end of the straight core, and the straight core penetrates through the drainage port to the pipeline part at the inner end of the drainage tube body. The utility model utilizes the metal guider to guide the drainage tube to directly reach the drainage position, the operation is simple, and the damage is small; the self-fixing function is realized, the use is convenient, and the disassembly is convenient; due to the design of a plurality of side holes, the pipe is not easy to block; the design is simple and the practicability is strong; the production process is simple and the cost is low.

Description

Drainage tube with guider

Technical Field

The utility model relates to a drainage tube with a guider.

Background

The drainage tube is a common device in clinical drainage, and can be fixed in a body by inserting a drainage tube and fixing by a suture. However, the prior drainage tube has the following defects: difficulty in placement; the suture operation is complicated, the damage to the patient is large, and the pain of the patient can be caused by pulling the suture; the stitches must be removed subsequently.

Disclosure of Invention

The utility model discloses overcome prior art's above-mentioned defect, provide a drainage tube of taking the guide ware that conveniently puts into, the damage is less, and need not to carry out the suture and demolish.

In order to achieve the above object, the utility model adopts the following technical scheme:

a drainage tube with a guider comprises a drainage tube 1, a water sac 2 and a metal guider 3;

the drainage tube 1 is Y-shaped, one end of the drainage tube is positioned in the body, a plurality of side holes 13 are formed in the tube wall of the inner end of the body, and the other two ends of the drainage tube are positioned outside the body and are respectively a drainage port 11 and a water injection port 12; the drainage tube 1 is of a partial common-tube double-cavity structure consisting of a thick tube and a thin tube, the thick tube and the thin tube are not communicated with each other, the thick tube is communicated with the inner end of the drainage tube 1 and the drainage port 11, and the thin tube 12 is communicated with the water injection port 12 and the water sac 2; the water sac 2 is tightly close to the inner side of the body wall 4, and is wrapped and fixed in the middle of the drainage tube 1; the metal guide 3 comprises a straight core with a tip end and a handle 31 fixed at the other end of the straight core, and the straight core penetrates through the drainage port 11 to the pipeline part at the inner end of the drainage tube 1.

Further, the water sac 2 is partially co-walled with the drainage tube 1.

Further, the straight core is hollow.

Furthermore, the drainage tube is made of natural rubber, silicon rubber or polyvinyl chloride PVC, and the specification can be designed into various specifications according to requirements, such as F22, F20, F18, F16, F14 and the like.

Furthermore, the metal guide is made of aluminum or stainless steel.

The utility model has the advantages that: the metal guider is used for guiding the drainage tube to directly reach the drainage position without expanding a channel by the hemostatic forceps, so that the operation is simple and the injury is small; the double-cavity balloon design enables the drainage tube to have a fixing function, is convenient to use, is not easy to fall off and is convenient to dismantle; due to the design of a plurality of side holes, the pipe is not easy to block; the design is simple, the practicability is strong, and the drainage device can be widely applied to postoperative drainage of general surgery, urinary surgery, obstetrics and gynecology, thoracic surgery and the like; the production process is simple and the cost is low.

Detailed Description

The invention will be further explained with reference to the accompanying drawings:

The water sac 2 and the drainage tube 1 are partially co-walled. The straight core is hollow. The drainage tube is made of natural rubber, silicon rubber or polyvinyl chloride PVC, and is designed into various specifications according to requirements, such as F22, F20, F18, F16, F14 and the like. The metal guide is made of metal such as aluminum or stainless steel.

The utility model discloses a use method is: cutting the length of the end of the side hole of the drainage tube 1 according to the requirement, inserting the metal guider 3 into the drainage tube 1 from the drainage port 11 when in use, wherein the length is suitable for extending into the front end of the drainage tube 1, and guiding the drainage tube 1 to reach a drainage part; the water sac 2 is placed in a body cavity such as a bladder and a renal pelvis, and the guider 3 is withdrawn; injecting a proper amount of water into the water sac 2 through the water injection port 12 for expansion, so that the drainage tube 1 is fixed in the body wall 4; the drainage port 11 is externally connected with a drainage bag to collect drainage liquid; when the drainage tube is pulled out, the drainage bag is taken down, water in the water sac 2 is pumped out, and then the drainage tube 1 is pulled out.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
