Description

a urinary catheter

technical field

The utility model relates to the technical field of medical supplies, in particular to a urinary catheter for collecting chyluria.

Background technique

In order to assist the diagnosis of chyluria, it is usually necessary to insert a urinary catheter under the cystoscope to collect the urine produced in the patient's left and right renal pelvis for detection, and to provide a basis for subsequent treatment by detecting the properties of the urine. Currently clinical

Usually, one end of two thin straight tubes is inserted into the kidneys through the urethra, bladder, etc., and at the same time, the thin straight tubes are tied to the main urinary collecting tube (ie: collecting the urine produced in the bladder), so as to fix the two Thin straight tube. However, there are problems with this method: when the patient is moving, the straight tube inserted into the kidney end is easy to move or fall off; the other three tubes are connected to three urine collection bags respectively, which is very inconvenient for the patient to move, and the doctor also needs to identify the urine bag It belongs to that place, which increases the mental burden of doctors.

SUMMARY OF THE INVENTION

In order to solve the shortcomings and deficiencies proposed in the above content, the present utility model provides a urinary catheter, which innovatively designs a main urinary collection tube, a water bladder tube, a first pipeline and a second pipeline, and a urinary catheter with 4 channels as a whole . Its technical solutions are as follows:

A urinary catheter comprises a main body, a urine inlet hole located at the front end of the main body tube, and a urine collection bag located at the tail end of the main body tube. The inlet of the water bladder tube outside the lumen is injected into the water bladder located below the urine inlet hole, and the urine enters the main urine collection tube through the urine inlet hole and then is discharged into the urine collection bag. The first pipe of the urinary catheter is connected to the second pipe of the second urinary catheter, and the introduced urine is respectively discharged into the urine collection bag through the first pipe and the second pipe.

Further, the urine collection bag includes three cavities, namely the first urine collection bag, the main urine collection bag, and the second urine collection bag, and the three urine collection bags are respectively connected with the first pipeline, the main urine collection pipe and the second pipe. .

Further, the urine collection bag is provided with a scale line indicating the amount of urine.

Further, the first urine collection bag and the second urine collection bag are provided with indicator strips marked left and right.

Further, the tail end of the urine collection bag is provided with a water outlet valve.

Further, the material of the main body pipe, the left side pipe and the right side pipe is medical rubber.

Further, the material of the urine collection bag is medical transparent plastic.

Further, the material of the water outlet valve is medical plastic.

The beneficial effects are as follows:

1. The urinary catheter provided by the utility model, by fitting the urinary catheter catheters on both sides of the renal pelvis into the first pipeline and the second pipeline, is conducive to the fixation of the urinary catheter, and simultaneously can prevent the urinary catheter from being displaced or displaced. fall off;

2. There is no urine collection bag matched with the urinary catheter on both sides of the renal pelvis clinically so far. Using the catheter provided by the utility model, the urine generated by the patient's renal pelvis directly passes through the first urinary catheter through the urinary catheters on both sides. The pipeline and the second pipeline are respectively discharged into the first urine collection bag and the second urine collection bag, which is convenient for the collection of urine, and the water outlet valve can be directly opened for inspection, which simplifies the operation steps;

3. In the past, the three tubes were connected to three urine collection bags respectively, which was very inconvenient for the patient to move. The urinary catheter provided by the utility model integrates the tube bag, which facilitates the movement of the patient and reduces the burden on the patient.

4. The indicator strip on the urine collection bag can prevent the confusion of the left and right ureteral catheters, reducing the mental burden of the doctor.

5. The scale line on the urine collection bag is convenient for patients or doctors to grasp the amount of urine collection.

Detailed ways

The technical solutions are described below with reference to the accompanying drawings of the present invention.

Referring to Figures 1 to 6, a urinary catheter includes a main body 1, a urine inlet hole 2 at the front end of the main body tube, a urine collection bag 3 at the tail end of the main body tube, and a water bladder 4, a water bladder The bladder tube 5 and the main urine collection tube 6, the water is injected into the water bladder 4 located under the urine inlet hole 2 from the water bladder tube inlet 7 outside the cavity of the main body tube 1, and the urine in the bladder enters the main urine through the urine inlet hole 2. The urine collection tube 6 is then discharged into the urine collection bag 3, and the outer wall of the main body tube is also provided with a first pipe 10 connected to the first urine introduction pipe 8, and a second pipe 11 connected to the second urine introduction pipe 9. The introduced urine It is discharged into the urine collection bag 3 through the first pipeline 10 and the second pipeline 11 respectively.

Before use, the outlet valve 17 is in a closed state. Insert the urine inlet hole 2 of the main body tube 1 and the water bladder 4 into the bladder through the urethra, and inject 15ml of normal saline into the water bladder 4 through the water bladder tube inlet 7. Due to the expansion of the water bladder 4, the main body tube 1 is firmly fixed. . With the assistance of cystoscope, the first urinary catheter 8 and the second urinary catheter 9 pass through the urethra and bladder, and are finally inserted into the kidneys on both sides, and the other end 8 of the first urinary catheter is inserted into the first pipe 10, the second The other end of the urinary catheter 9 is inserted into the second pipe 11, so that the urinary catheter is firmly fixed, and then the first pipe 10 is connected with the first urine collection bag 12, the main urine collection pipe 6 and the main urine collection bag 13. When connected, the second conduit 11 is connected to the second urine collecting bag 14, at this time, the urine produced by the bladder and the renal pelvis on both sides can be respectively discharged into their respective urine collecting bags. Medical staff or patients can obtain the amount of urine through the scale line 15 on the urine collection bag, and can also use the indicator bar 16 to distinguish which side of the renal pelvis is being collected, and open the water outlet valve 17 to receive urine for inspection.

In addition, the main body pipe 1, the first pipe 10 and the second pipe 11 are made of medical rubber, the urine collection bag 3 is made of medical transparent plastic, and the water outlet valve 17 is made of medical plastic.
