Description

urinary catheter

technical field

The utility model relates to the technical field of medical devices, in particular to a catheter for urine drainage.

Background technique

Disposable catheters currently in use include common disposable double-lumen catheters for drainage of urine and triple-lumen catheters for flushing. Common double-lumen catheters are simply used for indwelling catheters Drainage of urine, three-lumen catheter is generally indwelling after urological surgery to flush the bladder, etc. If the patient needs to measure the bladder pressure during the indwelling of the existing double-lumen catheter, a disposable needle is used to puncture the lumen at the junction of the catheter and the disposable drainage bag, and then the infusion tube is connected to measure the bladder pressure. To measure bladder pressure, it is necessary to repeatedly puncture the urinary catheter with a disposable needle. For example, although a three-lumen catheter can be directly connected to measure bladder pressure, patients who have indwelled a general double-lumen catheter need to replace the catheter for indwelling in order to measure bladder pressure, and the lumen of the three-lumen catheter Large and repeated catheter tube changes can increase patient discomfort. Therefore, the urinary catheter under the existing conditions is used for these operations such as the measurement of bladder pressure, and repeated separation and puncture all have the following disadvantages: the one is that the catheter is easily damaged by repeatedly operating the needle with a needle; Repeated needle punctures may cause needlestick injuries to medical staff and increase occupational injuries of nurses; third, if it is necessary to measure bladder pressure, it will be replaced with a three-cavity catheter, which will increase the cost and increase the workload of medical staff, which will bring harm to nursing work. Inconvenience will also increase the pain of the patient.

Utility model content

The technical problem to be solved by the utility model is to provide a urinary catheter, which can solve the problem that when the patient needs to measure the bladder pressure during the indwelling catheter, it is necessary to use a needle to puncture the lumen at the junction of the catheter and the drainage bag and then connect the transfusion. The catheter can be used to measure the bladder pressure, which will easily cause damage to the catheter and increase the occupational injury and workload of the nurse, increasing the cost and pain of the patient.

In order to solve the above problems, the technical solution of the utility model is: this urinary catheter includes a tube body, the insertion part of the tube body is provided with a closed air bag, and the closed air bag passes through the air supply tube and the indicator outside the tube body. The valves are connected to each other, and a side wall communication pipe communicating with the pipe body is provided at the joint between the side wall of the pipe body and the drainage bag, and a plug cap is provided on the port of the side wall communication pipe.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following beneficial effects:

The utility model adds a small side wall communication tube at the interface between the original catheter and the drainage bag, which is used to connect the pressure measuring device to measure the bladder pressure. In this way, when a patient with an indwelling three-lumen urinary catheter needs to measure the bladder pressure, he can connect the infusion tube through the side wall connecting tube for measurement, so that the patient can measure the bladder pressure without changing the three-lumen urinary catheter, which can reduce the cost of the catheter. Re-indwelling, reducing repeated indwelling catheters, reducing the occurrence of infection, and at the same time can reduce the patient's discomfort caused by re-dwelling catheters, and also reduce the workload of nurses. At the same time, the improved disposable urinary catheter with side tubes can be directly connected to the infusion tube for bladder pressure measurement, which can reduce the needle-stick injuries of medical staff that may be caused by repeated punctures of disposable needles, and reduce the probability of occupational exposure of medical workers , To a certain extent, it also saves the human resources of nurses. The disposable urinary catheter of the utility model is safe and hygienic, can be used for long-term indwelling urinary catheter for common patients to drain urine, and is convenient for bladder pressure measurement.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

The urinary catheter of Fig. 1 comprises a tube body 1, and the insertion part of the tube body 1 inserted into the urethra is provided with a closed air bag 3, and the closed air bag 3 is communicated with the indicating valve 2 arranged outside the tube body 1 through the air supply tube 6, and the indicating valve 2 Connect the inflating device, inflate the closed air bag 3 through the indicator valve 2, and seal the urethra after the closed air bag expands; the side wall connecting the tube body 1 and the drainage bag is provided with a side wall communication tube 4 communicating with the tube body 1, and the side wall is connected to the tube body 1. The port of the wall connecting tube 4 is provided with a plug cover 5; through the side wall connecting tube 4, it can be directly used to connect the pressure measuring device to measure the bladder pressure, and the bladder pressure can be measured without changing the three-chamber urinary catheter, which can reduce the The re-indwelling of the catheter can reduce the repeated indwelling of the catheter, reduce the occurrence of infection, and at the same time reduce the discomfort of the patient caused by the re-indwelling of the catheter, and also reduce the workload of the nurses. When the nozzle of the side wall connecting pipe 4 is not connected with the pressure measuring device, it is sealed with a cover plug 5 .
