[0002] Catheterization is the process of inserting a catheter through the urethra into the bladder to drain urine. The purpose is to collect uncontaminated urine specimens for examination and to assist urination. Urine collection bags are medical devices frequently used in catheterization, and are used clinically to collect urine, record urine volume, and observe urine properties.

[0003] At present, the urine collection bag connected to the catheter in the hospital is fastened to the hospital bed by a hanging rope. Due to the heavy daily nursing tasks of medical staff, when the urine in the urine collection bag reaches a certain amount, the medical staff or the patient fails to replace the urine collection bag in time, and the patient moves his limbs, which will cause the urine in the urine collection bag to flow back. The refluxed urine will carry bacteria along the catheter back to the urethra, which can easily lead to urinary tract infection.

[0004] Therefore, it is necessary to develop an anti-reflux urine collecting bag, which achieves the purpose of anti-reflux of urine through a guide sleeve, a valve and a flexible block. Utility Model Content

[0005] In order to overcome the disadvantage that when the urine in the urine collecting bag reaches a certain amount, the medical staff or the patient fails to replace the urine collecting bag in time, the patient's limb movements will cause the urine in the urine collecting bag to flow back, and the backflow of urine will carry bacteria along the catheter back to the urethra, thus easily causing urinary tract infection, the utility model provides an anti-backflow urine collecting bag, which achieves the purpose of anti-backflow of urine through a guide sleeve, a valve and a flexible block.

[0006] The technical solution is: an anti-backflow urine collecting bag, including a urinary catheter, a urine collecting bag and a one-way ventilation valve. A guide sleeve is fixedly connected to the opening of the urine collecting bag, a urinary catheter is inserted in the guide sleeve, and the urinary catheter is connected and communicated with the urine collecting bag. A one-way ventilation valve is installed on the urine collecting bag, and it also includes a valve and a flexible block. The flexible block is fixedly connected to one side of the guide sleeve located in the urine collecting bag, and the flexible block is connected to the valve. A step surface is provided on one side of the guide sleeve located in the urine collecting bag, and the valve rotates to cooperate with the step surface on the guide sleeve.

[0007] As a further preferred scheme, it also includes a guide plate, a push plate, an alarm and a sensor block. A guide plate is arranged inside the urine collecting bag, and the guide plate divides the inside of the urine collecting bag into two interconnected spaces, an inner space and an outer space. Slide grooves are provided on both sides of the guide plate, and a push plate is slidably arranged between the two slide grooves. An alarm is embedded in the urine collecting bag, and the alarm is located on one side of the urine collecting bag and is connected to the sensor block, and the sensor block is connected to the alarm signal.

[0008] As a further preferred embodiment, it also includes elastic bandages, Velcro and Magic buckles. Two elastic bandages are connected to both sides of the urine collecting bag, the ends of the two elastic bandages on one side of the urine collecting bag are connected to the Magic buckles, and the ends of the two elastic bandages on the other side of the urine collecting bag are connected to the Magic buckles, and the Magic buckles are adhered to the Velcro.

[0011] As a further preferred solution, it also includes scale lines, and the urine collecting bag is provided with scale lines.

[0012] The beneficial effects of the utility model are as follows: 1. The discharged urine flows into the urine collecting bag along the urinary catheter, and the urine pushes the valve to separate from the step surface on the guide sleeve and flows into the urine collecting bag. When the patient's limbs move to cause the urine in the urine collecting bag to flow back, the urine pushes the valve in the opposite direction to fit the step surface on the guide sleeve, thereby closing the guide sleeve, preventing the urine from flowing back when the patient moves his limbs, and avoiding the urine carrying bacteria to flow back and cause urinary tract infection.

[0013] 2. After urine enters the urine collecting bag, it passes through the external space and internal space between the guide plate and the urine collecting bag. Under the action of pressure, the urine will push the push plate to slide and contact the sensor block, and then activate the alarm to remind the patient or medical staff, thereby preventing the medical staff or patient from failing to replace the urine collecting bag in time.

[0014] 3. Unfold the elastic bandage and wrap it around your leg and adjust it to the appropriate position. Then glue the Velcro and Velcro together to fix the urine collection bag on your leg, so that the patient can carry the urine collection bag conveniently when moving.

A step surface is provided on the side of the guide sleeve 6 located in the urine collecting bag 2, and the valve 7 rotates to cooperate with the step surface on the guide sleeve 6.

[0024] When it is necessary to use the urine collecting bag 2 for the patient, the medical staff connects one end of the catheter 1 to the patient's urethra, and then buckles the urine collecting bag 2 to the bed through the hanging rope 16. The urine discharged by the patient flows into the urine collecting bag 2 along the catheter 1, and the urine pushes the valve 7 to rotate with the flexible block 8 as the center, so that the valve 7 is separated from the step surface on the guide sleeve 6. At this time, the urine collecting bag 2 is opened, and the urine flows into the urine collecting bag 2. The gas in the urine collecting bag 2 is discharged through the one-way ventilation valve 1201 to maintain the internal air pressure balance of the urine collecting bag 2. When the patient's limb movement causes the urine in the urine collecting bag 2 to flow back, the urine pushes the valve 7 in the opposite direction to rotate with the flexible block 8 as the center, so that the valve 7 fits with the step surface on the guide sleeve 6, thereby closing the guide sleeve 6 to prevent the urine from flowing back when the patient moves his limbs, and to avoid the backflow of bacteria carried by urine to cause urinary tract infection.
