Description

Technical Field

[0001] The utility model belongs to the technical field of urine collecting bags, and in particular relates to a urine collecting bag suitable for bladder flushing. Background Art

[0002] Bladder irrigation involves using a catheter to instill a solution into the bladder and then draining it out using a siphon. In ICUs, for patients with long-term urinary catheters, bladder irrigation helps maintain unobstructed urine flow and remove foreign matter such as blood clots, mucus, and bacteria from the bladder. It can also be used to treat certain bladder conditions, such as cystitis and bladder tumors, thereby preventing infection.

[0003] However, currently, double-lumen urinary catheters are commonly used in clinical practice. During catheterization, a urine bag is connected to the bladder via the catheter to collect and store urine. When bladder irrigation is required, a scalp needle is used to puncture the end of the catheter and connect it to the bladder for bladder irrigation. However, this method can easily lead to catheter damage after multiple punctures. The scalp needle can easily fall out during irrigation, causing leakage and even puncturing the patient. Leakage also increases the risk of pressure sores for patients, greatly increasing the risk of injury and illness for patients and the workload of medical staff. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a urine collecting bag suitable for bladder flushing, which does not puncture or damage the urinary catheter during bladder flushing and avoids causing urinary tract infection and urine leakage.

[0005] In order to solve the above technical problems, an embodiment of the present utility model provides a urine collection bag suitable for bladder flushing, including a bag body, on which a urinary tube, a urinary catheter pipe and a flushing pipe are provided. One end of the urinary catheter pipe is provided with a urinary catheter connector, and the other end is connected to the bag body. The flushing pipe is obliquely arranged on one side of the urinary catheter pipe and is connected with the urinary catheter pipe to form a Y shape. A flushing connector is provided at the port of the flushing pipe; the urinary tube is arranged at the bottom of the bag body, and a urinary valve is provided on the urinary tube.

[0006] Wherein, it also includes a flow-stopping clamp, which is installed on the urinary catheter pipe and between the urinary catheter pipe and the bag body.

[0007] The interior of the flow-stop clamp has a hollow narrow opening, and an arc-shaped pressing position is provided on the side.

[0008] Wherein, a one-way valve is also provided on the flushing pipeline.

[0009] Among them, the one-way valve is a one-way ball valve, a valve cavity is provided in the one-way ball valve, a hollow frame and a piston ball are provided in the valve cavity, the hollow frame is provided at the liquid outlet of the valve cavity, the piston ball is provided in the hollow frame and moves back and forth between the hollow frame and the liquid inlet of the valve cavity.

[0010] Wherein, the inner diameter of the liquid inlet of the valve cavity is smaller than the outer diameter of the piston ball, and the inner diameter of the liquid outlet is larger than the outer diameter of the piston ball.

[0011] The urinary catheter connector is in a pagoda shape, and the outer diameter of the urinary catheter connector gradually decreases in a direction away from the urinary catheter.

[0012] Wherein, the flushing joint adopts a positive pressure joint.

[0013] The liquid outlet of the urinary tube is also provided with a sealing cover. After the drainage is completed, the sealing cover rotates on the liquid outlet of the urinary tube to protect the liquid outlet of the urinary tube and prevent residual liquid from polluting the outside world.

[0014] Among them, the distance from the connection point of the flushing pipe and the urinary catheter pipe to the urinary catheter joint is 3~5cm to prevent the flushing pipe and the urinary catheter pipe from being too straight during the flushing process of the infusion set, causing the infusion set to fall off.

[0015] The beneficial effects of the above technical solution of the utility model are as follows:

[0016] With the urine collection bag of the present invention, medical staff only need to connect the infusion pump to the flushing connector and inject flushing fluid to flush the bladder. The flushing connector should be disinfected with an alcohol cotton swab before and after the connection. There is no need to puncture the catheter to connect it, which avoids the scalp needle from easily coming out during the flushing process, causing seepage or stabbing the patient, and reduces the risk of pressure sores caused by seepage in the patient. At the same time, when flushing the bladder, medical staff use a stop valve to block the flow of the urinary catheter to prevent the flushing fluid from being discharged into the bag through the urinary catheter, so that the injected flushing fluid can flow smoothly into the patient's body through the urinary inlet catheter.

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, the embodiment of the present invention provides a urine collection bag suitable for bladder irrigation, comprising a bag body 1, on which a urinary tube 2, a urinary catheter pipe 3 and an irrigation pipe 4 are provided. One end of the urinary catheter pipe 3 is provided with a urinary catheter connector 31, and the other end is connected to the bag body 1. A flow-stopping clamp 32 is installed between the urinary catheter pipe 3 and the bag body 1. The interior of the flow-stopping clamp 32 has a hollow narrow opening 321, and an arc-shaped pressing position 322 is provided on the side ( Figure 3 During bladder irrigation, the pressing position 322 on the side of the flow-stopping clip 32 is pressed to stop the flow, thereby preventing the flushing liquid from being discharged into the bag through the urinary catheter tube 3, and allowing the flushing liquid to flow smoothly into the patient's body through the urinary catheter.

[0024] The flushing pipe 4 is obliquely arranged on one side of the urinary conduit 3 and is connected to the urinary conduit 3 to form a Y shape. A flushing connector 41 is provided at the end of the flushing pipe 4. During bladder irrigation, the Y-shaped structure formed between the flushing pipe 4 and the urinary conduit 3 also slightly slows down the flow rate of the flushing and prevents liquid backflow to a certain extent. A one-way valve 42 is also provided on the flushing pipe 4. In this embodiment, Figure 2As shown, the one-way valve 42 is a one-way ball valve, used to prevent backflow of fluid within urinary tubes and catheters, which can cause urinary tract infections. A valve cavity 421 is provided within the one-way ball valve 42, which contains a hollow frame 422 and a piston ball 423. The hollow frame 422 is located at the valve cavity's liquid outlet 425. The piston ball 423 is located within the hollow frame 422 and moves back and forth between the hollow frame 422 and the valve cavity's liquid inlet 424. The inner diameter of the valve cavity's liquid inlet 424 is smaller than the outer diameter of the piston ball 423, while the inner diameter of the liquid outlet 425 is larger than the outer diameter of the piston ball 423. The diameter of the hollow hole in the hollow frame 422 is smaller than the outer diameter of the piston ball 423. When the liquid flows downstream from the valve cavity liquid inlet 424 to the liquid outlet 425, the piston ball 423 is pushed onto the hollow frame 422 by the liquid, and the liquid flows out from the valve cavity liquid outlet 425 through the hollow holes in the hollow frame 422; when the liquid flows countercurrently, the piston ball 423 is pushed to the liquid inlet 424 of the valve cavity. Since the outer diameter of the piston ball 423 is larger than the inner diameter of the liquid inlet 424, the piston ball 423 closes the liquid inlet, blocking the flow of liquid, thereby preventing the liquid from flowing out of the valve cavity liquid inlet 424, thereby preventing the backflow of liquid in the urinary tube and catheter from causing urinary tract infection.

[0025] The urinary tube 2 is disposed at the bottom of the bag 1 and is provided with a urinary valve 21 to facilitate the discharge of urine from the bag 1. The outlet of the urinary tube 2 is also provided with a sealing cap 22. After drainage is completed, the sealing cap 22 rotates onto the outlet of the urinary tube 1 to protect the outlet of the urinary tube 1 and prevent residual liquid from contaminating the outside world.

[0026] The urinary catheter connector 31 is in a pagoda shape, and its outer diameter gradually decreases in the direction away from the urinary catheter, so as to facilitate the connection of the urinary catheter connector to the urinary catheter connector.

[0027] The flushing connector 41 is a positive pressure connector, which can be used continuously and avoid needle stick injuries. It does not need to be replaced every time after use, which is convenient for disinfection.

[0028] The distance from the connection between the flushing pipe 4 and the urinary catheter pipe 3 to the urinary catheter joint 31 is 3 to 5 cm to prevent the flushing pipe and the urinary catheter pipe from being too straight due to positive pressure during the flushing process of the infusion set, causing the infusion set to fall off, and also to prevent the patient from being pressurized during turning over, which may cause the risk of pressure sores.

[0029] The working principle of this utility model is:

[0030] The urethral tube and flushing tube facilitate bladder flushing by simply connecting the urethral tube connector to the urinary catheter and then connecting the infusion set or syringe to the flushing connector. Before and after connection, the flushing connector only needs to be disinfected with an alcohol swab, making it easier for medical staff to flush the patient's bladder without having to puncture the urinary catheter with a pin. The one-way ball valve on the flushing tube and the Y-shaped structure formed between the flushing tube and the urethral tube also slow the flushing flow rate, reducing patient pain. The one-way ball valve also prevents liquid backflow, avoiding urinary tract infection caused by backflow of liquid in the urethral tube and urinary catheter. When used as a urine collection bag, the urine discharge tube and valve at the bottom of the bag facilitate the discharge of urine from the bag. A sealing cap is also provided at the liquid outlet of the urine discharge tube. After drainage is completed, the sealing cap rotates onto the liquid outlet of the urine discharge tube to protect the liquid outlet of the urine discharge tube and prevent residual liquid from contaminating the outside world.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
