Embodiment 1

[0021] Example 1: A cystostomy tube without a urine collection bag

[0022] A cystostomy tube that does not require a urine collection bag, such as figure 1 , 3 , 4 and 5, including the pipe wall 2, the fixed plate 5, the water bag 4 on the outer periphery of the pipe wall, the water injection valve 6 connected to the water bag and the piston valve 1 in the lumen 3, wherein the pipe wall 2 is connected with the fixed plate 5 As a whole, the water injection valve 6 is located on the fixed plate 5, and one end of the water bag 4 communicates with the water injection valve 6 through the fixed plate and the pipeline 10 in the pipe wall. The piston flap 1 in the tube cavity 3 is connected to the pipe wall 2, and the piston flap 1 has 3 piston vanes 11 .

Embodiment 2

[0023] Example 2: A cystostomy tube that does not require a urine collection bag

[0024] A cystostomy tube that does not require a urine collection bag as described in Example 1, wherein the piston valve 1 is composed of four piston valve leaves 11; the tube wall 2, the fixing plate 5, and the water bag around the tube wall 4 and the piston valve 1 in the lumen 3 are all made of medical silica gel.

[0025] The fixed plate 5 is integrated with the tube wall 2. The fixed plate 5 is 2 cm wide and 1 cm thick. It is used to hold the abdominal wall after the ostomy tube is inserted, and plays the role of external fixation to prevent the ostomy tube from slipping inward.

[0026] The water bag 4 surrounds the pipe wall 2, the far end 7 is 1 cm away from the inner mouth of the pipe wall, and the proximal end 8 communicates with the water injection valve 6 through the fixed plate and the pipeline 10 in the pipe wall. Since the length of the water bladder used is greater than the len...

Embodiment 3

[0029] Embodiment 3: the working method of cystostomy tube of the present invention

[0030] 1. Replace the cystostomy tube for the first time: remove the original cystostomy tube, measure the length and diameter of the fistula on the tube, select the appropriate bladder tube of the present invention, insert it along the fistula, and place the distal end of the tube into the bladder 3cm , the fixed plate is attached to the abdominal wall. Then use a syringe to inject saline through the water injection valve to inflate the water bladder. The pressure is that the water bag is just close to the wall of the fistula, and it is better that there is no extravasation of urine.

[0031] 2. Urination: When the bladder is full and needs to urinate, a sterile catheter is inserted along the fistula cavity, and the piston valve is gently stretched inward to enter the bladder. The urine will flow out along the sterile catheter automatically. After urination , pull out the catheter, the pis...

Abstract

The invention belongs to the field of medical equipment. Currently, a plurality of bladder stomas exist clinically, such as a mushroom-shaped bladder stoma, a Foley catheter and the like, and are connected with a urine collecting bag externally for a long time, so that the daily life of a patient is seriously influenced. The invention provides a novel bladder stoma which is provided with a pistonvalve, prevents urine from leaking, and does not require a urine collecting bag. The bladder stoma comprises a tube wall (2), a fixed plate (5), a water bag (4) on the periphery of the wall tube, a water injection valve (6) connected with the water bag, as well as a piston valve (1) in a tube cavity (3). The bladder stoma has the characteristics that: after normal saline is injected into the water bag, the bladder stoma can be fixed due to expansion of the water bag in the bladder, and expansion of the water bag in the bladder stoma can prevent urine in the bladder from leaking to fistula; the piston valve in the tube cavity can stop urine from flowing out, and when urination is required, a sterile catheter is inserted into the tube cavity to expand the piston valve for urinating. According to the bladder stoma, urination can be effectively controlled, and a cystostomy patient can relieve troubles of carrying the urine collecting bag along with the patient.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a cystostomy tube without a urine collection bag. Background technique [0002] For patients with long-term urinary retention such as neurogenic bladder and urethral obstruction, cystostomy is a commonly used clinical treatment. Such patients need to carry a cystostomy tube for a long time to achieve the purpose of long-term urine drainage and kidney protection. Although there are many kinds of cystostomy tubes clinically at present, such as mycosis cystostomy tube, Foley catheter, etc., another example is Chinese patent ZL96227439.9, the invention name is "urination controllable cystostomy tube"; Chinese patent ZL200720017469.1 , the cystostomy tubes involved in the invention titled "cystostomy tube" all have a common feature, that is, a urine collection bag should be connected externally for a long time, which seriously affects the daily life of the patient. [0003] If a cystos...
