Description

Three-cavity catheter

The technical field is as follows:

the utility model relates to a catheter, especially a three chamber catheters.

Background art:

catheterization is the insertion of a urinary catheter into the urinary bladder through the urethra to draw urine in order to relieve urinary retention, taking uncontaminated urine specimens for examination, measuring residual urine, measuring cold and heat sensation, volume and pressure of the bladder, and injecting contrast agents or drugs to aid diagnosis or treatment. But current two-chamber catheter, the lumen of dosing, washing and drainage sharing, can not accomplish to dose, wash and the drainage goes on simultaneously, also has the urine backward flow problem of being detained in the lumen when dosing or washing together with three chamber catheters, arouses retrogressive infection easily, difficult observation blocks the gasbag and has or not damaged moreover, when needing to change the catheter, leads to the urinary tract to be obstructed because of urinary tract inflammatory edema, the patient is painful to be difficult to endure, sometimes intubate difficulty.

The invention content is as follows:

the utility model provides a technical problem of catheter difficulty when overcoming the catheter that uses at present and washing and can not go on simultaneously, dose or wash the time delay in the intracavity urine backward flow, be difficult for observing the blocking gasbag have or not damaged, change the ureter, the utility model provides a simple structure, reasonable in design washes and the drainage can go on simultaneously, avoids pouring into the medicine or wash the urine backward flow when bladder, easily observes the blocking gasbag and has or not damaged, changes the ureter and easily succeeds, the three chamber catheters that the appearance is pleasing to the eye.

In order to realize the technical purpose, the utility model adopts the technical proposal that the three-cavity catheter consists of a drainage tube (1), a drainage hole (2) and a blocking air bag (3), and is characterized in that the end of the drainage tube (1) is provided with an injection hole (4), the insertion end of the drainage tube (1) is fixedly connected with the blocking air bag (3), the injection tube (5) and the blocking air bag inflation tube (6) are positioned on the inner wall of the drainage tube (1), the injection hole (4) is fixedly connected with a positive pressure infusion connector (7) through the tail end of the injection tube (5), the blocking air bag (3) is fixedly connected with a small air bag (8) and a check valve (9) through the tail end of the blocking air bag inflation tube (6), the tail end of the drainage tube (1) is fixedly connected with a locking quick-change luer connector (10), a forward valve (11) is arranged in the cavity at the front end of the injection tube (5), and a small air bag inflation hole (12) is arranged at the tail end of the blocking air bag inflation tube (6), a guide wire (13) can be inserted into the injection tube (5).

The utility model provides a pair of three chamber catheters adopts above-mentioned structure after, the drainage separates with the injection medicine lumen, and the intracavity of injection pipe front end is equipped with forward valve, is detained in the urine backward flow of lumen when can effectively avoiding the injection or wash the bladder, reduces the risk of retrograde infection, and can keep dosing, wash and the drainage goes on simultaneously. The small air bag is communicated with the blocking air bag, the fact that whether the blocking air bag is damaged or not in the bladder is easy to observe, so that the catheter can be replaced in time, when the catheter is replaced, the guide wire is inserted into the injection tube firstly, the damaged catheter is pulled out, the guide wire is kept in place, a new catheter is inserted along the guide wire, the operation is time-saving and labor-saving, and the success is easy. This three-chamber catheterization tubular construction is simple, reasonable in design, washes and the drainage can go on simultaneously, avoids injecting into the medicine or the urine backward flow when washing the bladder, easily observes and blocks the gasbag and has had or not damaged, and it is easy to succeed to change the ureter, and the appearance is pleasing to the eye, but the wide application is in the catheterization operation.

Description of the drawings:

fig. 1 is the concrete structural schematic diagram of the utility model:

1. drainage tube 2, drainage hole 3, blocking air bag 4, injection hole 5, injection tube 6, blocking air bag inflation tube 7, positive pressure infusion joint 8, small air bag 9, check valve 10, locking replacement luer joint 11, positive direction valve 12, small air bag inflation hole 13, guide wire

The specific implementation mode is as follows:

the three-cavity catheter is made of polyurethane material. The end of the drainage tube 1 is provided with an injection hole 4, the insertion end of the drainage tube 1 is fixedly connected with a blocking air bag 3, the blocking air bag 3 is wrapped on a small section of the drainage tube 1, the side wall of the drainage tube 1 at the front end of the blocking air bag 3 is provided with a plurality of drainage holes 2, the injection tube 5 and the blocking air bag inflation tube 6 are positioned on the inner wall of the drainage tube 1, the injection hole 4 is fixedly connected with a positive pressure infusion connector 7 through the tail end of the injection tube 5, the blocking air bag 3 is fixedly connected with a small air bag 8 and a check valve 9 through the tail end of the blocking air bag inflation tube 6, the small air bag 8 is wrapped on the small section of the blocking air bag inflation tube 6, the tail end of the drainage tube 1 is fixedly connected with a quick-change locking luer connector 10, a forward valve 11 is arranged in the cavity at the front end of the injection tube 5, the tail end of the blocking air bag inflation tube 5 is provided with a small air bag inflation hole 12, and a guide wire 13 can be inserted into the injection tube 5.

When the device is used, an operator carefully checks whether the air bag leaks or not, whether the drainage tube, the injection tube, the air bag blocking inflation tube and the small air bag inflation hole are smooth or not, and whether the check valve, the positive pressure infusion connector and the quick locking luer connector are smooth or not, or whether air leakage or liquid leakage exists or not. After the examination is qualified, air in the air bag is exhausted, the front end of the catheter is lubricated by a paraffin oil cotton ball, the catheter is held by a hemostatic forceps to be slowly inserted into a urethral orifice, a male enters about 20-22cm, a female enters about 4-6cm and flows out of the urine, then the catheter is inserted by about 1 cm, water or gas is injected into the small air bag and the blocking air bag through a check valve at the tail end of the blocking air bag, 15-25mL of adult male and 20-30mL of female are connected with a drainage bag through a quick-change locking luer connector at the tail end of a drainage tube, liquid medicine is injected through a positive pressure infusion connector at the tail end of the injection tube during medicine injection or flushing, if the catheter needs to be replaced, the guide wire is inserted into the injection tube, the damaged catheter is pulled out, the guide wire is kept in place, and a new catheter is inserted along the guide wire, so that the catheter can be used.
