Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a bladder flushing and drainage bag. Background Art
[0002] Bladder flushing technology is a method of pouring flushing fluid into the bladder through a three-lumen urinary catheter, and then using the siphon principle to drain the poured fluid out. This technology is often used for flushing after urological surgeries such as transurethral prostatectomy, transurethral prostatectomy, bladder tumor resection, and open prostatectomy. It is a common nursing technology in urology. Continuous bladder flushing is fast and has a large amount of fluid discharge. In order to facilitate the collection of the drained fluid and reduce the frequency of dumping, it reduces the chance of infection and reduces the workload of nurses.
[0003] The product currently used in the department is a disposable anti-reflux drainage bag produced by a medical device company. The capacity of the drainage bag is 5000 ml. During use, the following shortcomings are generally found: (1) The drainage bag has only one outlet. When a blood clot blocks the outlet, the drainage fluid often cannot be poured out. In this case, a new drainage bag can only be replaced, which increases the nursing workload and the economic burden on patients. (2) There is a drip pot on the drainage bag, through which the drip pot can be used to observe the dripping rate and whether the drainage is unobstructed. However, the drip pot currently has no anti-reflux device. When poor drainage easily leads to liquid reflux, the drip pot is filled with liquid, and it is impossible to observe the dripping rate and whether the drainage is unobstructed. Utility Model Content

When the pressure in the space formed by the first elastic shell 9 and the second elastic shell 10 is greater than the pressure outside, under the action of the pressure difference, the close ends of the first elastic shell 9 and the second elastic shell 10 are separated to keep the drainage fluid entering the diversion shell 2; when the pressure in the space formed by the first elastic shell 9 and the second elastic shell 10 is less than the pressure outside, under the action of the pressure difference, the end of the second elastic shell 10 outside squeezes the end of the first elastic shell 9, and the first elastic shell 9 makes its end close to the end of the second elastic shell 10 under its own elastic action, thereby maintaining the sealing structure to prevent backflow, and a concave portion is provided at the bottom of the bag body 1, and a water outlet is provided at the bottom of the concave portion, a diversion pipe 11 is installed on the water outlet, and a stop valve 12 is installed on the diversion pipe 11.
[0023] The bag body 1 is made of medical silica gel, the diversion shell 2 is made of transparent hard plastic, and the diversion shell 2 is adhered to the bag body 1. Specifically, it can be connected by a soft adhesive sheet, which is arranged on the outer side of one end where the diversion shell 2 and the bag body 1 are in contact.
[0024] The first tube body 4, the second tube body 7 and the drip pot 5 are all made of transparent plastic. The first elastic shell 9 and the second elastic shell 10 are both made of elastic silicone.
[0025] There are two water outlets. When one of the water outlets is blocked by a blood clot, the other water outlet can be used. When both water outlets are blocked, the bag can be inverted to allow the blood clot to settle into one of the recessed parts, ensuring that the other water outlet is unobstructed, making it convenient to pour out the liquid inside the bag.
[0026] A pull ring 13 made of plastic is embedded in the top of the bag body 1 , and a hand-carrying hole 14 and a plurality of strap holes 15 are provided on the pull ring 13 .

[0028] The bag body 1 is provided with a volume scale 17 for measuring the volume of the drainage fluid.
[0029] When the bladder flushing drainage bag of the utility model is in use, the drainage liquid drips into the drip pot through the drainage tube, and the liquid in the drip pot enters the space between the first elastic shell 9 and the second elastic shell 10 through the diversion hole 8 on the second tube body 7. Due to the relatively large internal pressure, the ends of the first elastic shell 9 and the second elastic shell 10 are stretched open, and the drainage liquid flows into the diversion shell 2 and then enters the bag body through the diversion shell 2. When reflux occurs, the pressure on the side of the bag body is relatively large, and the drainage liquid collected in the bag body squeezes the outermost second elastic shell 10. Since the first elastic shell 9 and the second elastic shell 10 are both elastic bowl-shaped structures, when squeezing the outside of the second elastic shell 10, only the ends of the first elastic shell 9 and the second elastic shell 10 will be tightly attached, thereby maintaining a sealed structure to prevent reflux.
