Example 1
In this embodiment, the steps of applying the balloon pressure monitoring catheter are as follows:
1. 40 patients in general surgery who need indwelling catheters are selected, wherein 26 men and 14 women are divided into a control group and a test group by adopting a random digital table method, the indwelling disposable medical catheters of the two groups of patients are both 16Fr and have no urinary system diseases, the test group adopts a balloon pressure monitoring type catheter, and the catheter is sterilized by a supply room before use and is reserved.
2. And (3) connecting the three-way pipe with the side branch end of the catheter air bag, connecting a one-way valve and an air bag pressure monitoring meter at the same time, checking the air bag pressure monitoring meter every 8h shift, and connecting a 20ml syringe to replenish or discard the liquid volume with the corresponding volume if the indication needle shows abnormality. When the control group is handed over by a nurse, a 20ml syringe is connected with the side branch of the air bag based on the aseptic principle, the liquid in the air bag is pumped back, whether the volume is 10-15ml or not is checked, if the volume is abnormal, the liquid with the corresponding volume is supplemented or discarded, and the accuracy of the liquid content of the air bag of the two groups of patients is observed, whether the urine exists, the urethra is damaged, the urine leaks, the ureter slips and the like.
3. The side branch end of the air bag of the original disposable medical catheter is internally provided with a check valve which is made of rubber, and liquid or gas in the side branch end can seep out by fixing or kneading, so that the leakage and air leakage of the air bag can be caused. The test group adopts the air bag pressure monitoring type catheter, the one-way valve is made of stable materials, and the valve is opened only when the 20ml syringe is connected, so that liquid leakage and air leakage of the air bag are avoided.
4. The patient of experimental group uses gasbag pressure monitoring formula catheter in-process, and the nurse only need observe the position that the pointer pointed in the gasbag pressure indicator when handing over shift, just can clearly know how much of catheter gasbag content liquid volume, avoids the nurse to connect repeatedly, pumpback liquid in the gasbag, not only reduces nurse's work load, guarantees the accuracy of gasbag content liquid volume simultaneously, reduces patient's urinary tract infection's possibility, increases the life of catheter gasbag.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
