Discharged to the body, reducing the difficulty of urinating due to blood clots or secretions blocking the drainage hole, reducing the number of re-intubation times, and reducing the additional pain of the patient.

Description

A multi-lumen urinary catheter

technical field

The utility model belongs to medical equipment, in particular to a multi-cavity urinary catheter with scale side holes and scale grooves.

Background technique

Indwelling urinary catheterization is one of the most widely used nursing operations in clinical practice. At present, disposable double-lumen or triple-lumen silicone balloon catheters are mostly used. This catheter requires female patients to insert 4-6cm into the urethra during operation, and male patients to insert it into the urethra. The urethra is 20-22cm, insert 7-10cm after the urine flows out from the catheter, and inject 0.9% sodium chloride solution corresponding to the volume of the catheter balloon into the balloon to drain the drainage hole of the catheter fixed in the bladder. At present, there are the following problems in the clinical use of the urinary catheter: 1. There are 1-2 drainage holes at the front end of the urinary catheter. When draining urine, if the patient has a lot of bleeding in the bladder, it is easy to cause the drainage hole of the urinary catheter. Blockage is not conducive to the discharge of urine; 2. During the indwelling catheter, the urinary catheter stimulates the urethra to easily produce secretions, which provides a place for the reproduction of bacteria. If the drainage is not sufficient, it is easy to cause urinary tract infection; it increases the additional cost of the patient. pain.

Utility model content

The technical problem to be solved by the utility model is to provide an air bag catheter, which can drain blood or secretions well when the drainage hole of the catheter is blocked.

In order to solve the above problems, the utility model adopts the following technical solutions: a multi-cavity urinary catheter, comprising: a catheterization cavity, an air bag and an air bag cavity, the top of the catheterization cavity is provided with a drainage hole, and the air bag is placed in a circular shape in the catheter The outer wall of the urinary catheter is connected with the balloon cavity in the catheter, the end of the balloon cavity is connected with the balloon catheter, and the end of the balloon catheter is provided with an inflation valve; the outer wall of the catheter is provided with a side hole, and the side hole is connected to the A cavity inside the catheter. Connection, the end of lumen A is connected to the catheter.

Preferably, a scale groove is provided on the outer wall of the urinary catheter.

Preferably, a scale is engraved inside the scale groove.

The characteristics or advantages of the urinary catheter: 1. During the period of indwelling the urinary catheter, 1-2 side holes are added at the head end of the urinary catheter to facilitate the drainage of urine and reduce the occurrence of catheter blockage. It can also inject flushing liquid through the urinary catheter channel, which can flush bladder secretions, blood, and pus, and is beneficial to drainage and prevention of infection; injection of antispasmodic pain relief or topical anesthetics can treat bladder spasm, etc., which can effectively relieve the pain of patients; 2. Place After the catheter, the secretions in the urethra can be discharged from the urethra through the side hole in the catheter, and the drainage will be more sufficient, thereby effectively preventing and treating urinary tract infections related to the indwelling catheter; 3. By adding a scale on the catheter This method can improve the accuracy of clinical operations and reduce the additional pain of patients.

Detailed ways

In order to make the above purpose, features and advantages of the utility model more obvious and understandable, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

With reference to Fig. 1, the urinary catheter 11 shown in Fig. 1 is a circular catheter made of silica gel, three cavities are arranged inside the catheter, and one or two drainage holes are arranged at the top of the catheter lumen 18 of the catheter 12. The end of the catheter is a water outlet hole, and the air bag 14 is set on the outer wall about 5cm away from the top of the catheter, and is close to the outer wall of the catheter. One end of the air bag cavity in the catheter passes through the outer wall of the catheter and The airbag 14 is connected, and the other end of the airbag cavity is connected with the balloon catheter 15, and an inflation valve 16 is provided at the end of the balloon catheter; a side hole 13 is provided at the side end of the chamber A, and the side hole is located at 4 to 18 cm from the drainage hole. Holes 13 may be provided in plural. The end of lumen A is connected with catheter 17 for inputting flushing fluid or therapeutic medicinal fluid.

Referring to Fig. 2, in order to control the length of the catheter inserted into the urethra, a plurality of scale grooves 19 are arranged on the outer wall of the catheter, and the inside of the groove 19 is engraved with a scale, for example: from the top of the catheter to 25cm, make one every 1cm Scale grooves, that is, engrave scales in the grooves at 1cm, 2cm, 3cm, 4cm...25cm respectively.

During the actual nursing operation, insert the top of the catheter into the bladder, inflate the air bag through the air bag cavity, and the expanded air bag is stuck in the bladder. The cleaning fluid is input into the catheter, and the cleaning fluid flows out from the side hole of chamber A, and the blood and secretions around the blocked drainage hole are washed away, and then the diluted blood and secretions are discharged from the body through the side hole and drainage at the same time.

The technical scope of this utility model is not limited to the content on the description, and there are many specific technical application solutions determined according to its claims. The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
