Description

Technical Field

[0001] The utility model relates to the technical field of medical consumables, in particular to a closed extension tube for a urinary catheter. Background Art

[0002] A urinary catheter is a tube made of rubber, silicone or plastic, which can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an airbag near the head end of the urinary catheter to fix the urinary catheter in the bladder and prevent it from slipping out easily, and the drainage tube is connected to a urine bag to collect urine;

[0003] At present, the well-known urinary catheter is a commonly used medical consumable in clinical practice, mainly used for inserting into the bladder through the urethra to drain urine. The material for making the urinary catheter is generally silicone, which is relatively soft. It is okay for female use, but for male use, due to different physiological structures, it is more difficult to insert. For some urinary catheters with an inflatable balloon, accidental pulling may cause urethral injury to the patient. Therefore, a closed extension tube for a urinary catheter is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a closed extension tube for a urinary catheter, which can effectively solve the problems proposed in the above background art.

[0005] To solve the above problems, the technical solution adopted by the utility model is: a closed extension tube for a urinary catheter, including an extension tube body, a urinary catheter and a urine bag. It is characterized in that one end of the extension tube is connected to the urine bag, and the other end of the extension tube is provided with a telescopic rubber sleeve section; the end of the telescopic rubber sleeve section is a joint tube, and one end of the urinary catheter is sleeved through the joint tube; a valve is arranged in the joint tube.

[0017] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0018] In addition, if the descriptions such as "first", "second", etc. are involved in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0019] Referring to Figures 1-3 , the present utility model provides a closed extension tube for a urinary catheter, including an extension tube body 1, a urinary catheter 2, and a urine bag 3. It is characterized in that one end of the extension tube body 1 is connected to the urine bag 3, and the other end of the extension tube body 1 is provided with a telescopic rubber sleeve section 1-1; the end of the telescopic rubber sleeve section 1-1 is a connecting tube 1-2, and the connecting tube 1-2 is sleeved with one end of the urinary catheter 2; a valve is arranged in the connecting tube 1-2, and the valve can prevent urine from flowing back from the urine bag 3 to the urinary catheter 2.

[0020] As a further preferred solution of the present utility model, a storage box 3-1 is arranged on the outer side of the urine bag 3; a guide wire is placed in the storage box 3-1 and taken out during use.

[0021] As a further preferred solution of the present utility model, a hanging strap 3-2 is further arranged on the outer side of the urine bag 3, and the hanging strap 3-2 is used to place a syringe, which is convenient for inflating the inflation balloon 2-31.

[0022] As a further preferred solution of the present utility model, the urinary catheter 2 is a three-lumen urinary catheter 2, including a main body part 2-1. The two ends of the main body part 2-1 are respectively a urine inlet 2-11 and a urine outlet 2-12. An inflow channel 2-2 is constructed inside the main body part 2-1. The two ends of the inflow channel 2-2 are respectively provided with a water outlet 2-21 and a water inlet 2-22, and a water injection soft valve 2-23 is arranged at the water inlet 2-22. When bladder irrigation is required, only water needs to be injected from the water injection soft valve 2-23. After the water enters the bladder from the water outlet 2-21, it is discharged into the urine bag 3 through the urine inlet 2-11.

[0023] As a further preferred embodiment of the present utility model, an anti - detachment channel 2 - 3 is further constructed inside the main body portion 2 - 1. An expansion bladder 2 - 31 is provided at one end of the anti - detachment channel 2 - 3 close to the water outlet 2 - 21, and an inflation control valve 2 - 32 is provided at the other end of the anti - detachment channel 2 - 3. During use, a syringe is taken out from the hanging strap 3 - 2 to inflate the inflation control valve 2 - 32, so that the expansion bladder 2 - 31 expands, thereby preventing the urinary catheter 2 from falling off.

[0024] As a further preferred embodiment of the present utility model, the extension tube body 1 and the urinary catheter 2 are made of rubber material.

[0025] As a specific embodiment of the present utility model: During use, a guide wire is taken out from the storage box 3 - 1, the guide wire penetrates into the urinary catheter 2 and exits from one end of the urinary catheter 2. Then the guide wire is first inserted into the urethra and reaches the bladder through the urethra. Subsequently, under the guidance of the guide wire, the urinary catheter 2 is gently pushed along the guide wire into the urethra until it reaches the bladder position. This can reduce the discomfort of the patient, and at the same time reduce the trauma and resistance during the insertion of the urinary catheter 2, and increase the stiffness and stability of the urinary catheter 2, which helps to avoid the twisting and displacement of the urinary catheter 2 and helps to keep the urinary catheter 2 in the correct position. Since the extension tube body 1 is connected later, a shorter urinary catheter 2 can be used, making it more convenient and fast to access the urethra. After the connection is completed, the joint tube 1 - 2 provided on the extension tube body 1 is aligned with the urine outlet 2 - 12 of the urinary catheter 2 for socket connection. When the patient accidentally pulls the extension tube body 1, the telescopic rubber sleeve section 1 - 1 on the extension tube body 1 is quickly stretched to offset the pulling force, effectively reducing the risk of urethral injury.

[0026] As required, the above - mentioned installation, setting, providing, or connection methods include but are not limited to installation, setting, or connection by means such as screws, riveting, welding, or socketing, fixing, etc., and the installation, setting, or connection method is selected according to the working scenario requirements.

[0027] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
