Examples

A cystostomy device for use as follows:

first, a puncture site is selected. For non-acute patients, the bladder filling and the bladder inner condition can be observed at the position 2-3cm above the pubic bone by using the B ultrasonic, and the bladder puncture point is determined; for emergency patients, when color ultrasound positioning cannot be performed, the puncture site needs to be judged according to the experience of a clinician, the Liu Da is equal [ Liu Da is, Wang Meng, Wang Guoshiguan and bladder fistulization operation type curative effect analysis [ M ]. Liaoning: Chinese medical guideline, 2018:297-298.] in clinical practice, the average height of the person is 170cm, the average weight is 65kg, and the puncture site is 2.0cm above the pubic symphysis and is taken as a middle value. The puncture depth is 0.5cm lower than that of the thin person and 0.5cm higher than that of the fat person, and particularly, the puncture depth of the fat person can be controlled by means of color ultrasound to prevent the occurrence of side injury.

After a puncture site is selected, a syringe extracts lidocaine from the puncture site and the site from the puncture site to the bladder wall for local anesthesia, the puncture needle 9 gradually exerts force and enters the bladder in the B ultrasonic monitoring direction or according to clinical experience judgment, when the extracted liquid is urine, the guide wire 8 is gradually sent into the bladder from the tail part of the puncture needle 9, the puncture needle 9 is pulled out from the fixed guide wire 8, the dilator 10 is used for skin expansion, the dilator 10 is slowly placed into the device shown in the figure 1 along the guide wire 8 after being pulled out, Liu is equal [ Liu Da is Wang Meng, Wang Guo Guang, curative effect analysis of bladder fistulization operation type [ M ]. Liaoning, Chinese medical guideline, 2018:297 and 298 ] calculates the length from the skin to the bladder and the required length after the bladder is emptied, generally 8-10cm, and the utility model discloses a deep placement and data collection method. The guide wire 8 is pulled out, 10-15cm of normal saline is injected from the water injection valve 3, the expandable saccule 5 is expanded, the catheter 11 is fixed in the bladder, the skin puncture point part is covered by the medical healing membrane, and the main cavity 1 of the hose is connected with the drainage bag 2.
