Description

Technical Field

[0001] The utility model relates to the technical field of medical device auxiliary equipment, in particular to a waterproof and aseptic sleeve bag suitable for hemodialysis catheters. Background Technique

[0002] As an important means for treating diseases such as acute and chronic renal failure, hemodialysis is widely used clinically. However, during the process of hemodialysis treatment, patients often need to carry dialysis catheters for a long time, which causes certain inconvenience to the daily life of patients. Especially in daily cleaning activities such as bathing, how to effectively protect the dialysis catheter from being soaked by water and prevent infection has become an urgent problem to be solved.

[0003] Existing solutions include using disposable sterile anal bags or waterproof transparent films to cover the catheter, but these methods have certain limitations. For example, the anal bag may cause water to seep in due to poor adhesion, while the waterproof transparent film may fall off or leak after long-term use due to material problems. In addition, these products often lack an intuitive indication function during use, making it difficult to immediately detect and handle the problem of poor adhesion. Content of the Utility Model

[0004] In view of the above problems, the utility model aims to provide a more safe, effective and easy-to-use waterproof and aseptic sleeve bag for hemodialysis catheters to solve the disadvantages of poor adhesion, easy leakage and lack of intuitive indication in the prior art.

[0005] The technical solution provided by the utility model is a waterproof and aseptic sleeve bag suitable for hemodialysis catheters, which includes a first film, an indication ring, a second film, and a catheter placement bag. One end of the catheter placement bag is closed, and the other end is provided with an opening. The opening is integrally formed with a ring of the second film. The periphery of the second film is integrally formed with an indication ring, and the periphery of the indication ring is integrally formed with a ring of the first film. When in use, the hemodialysis catheter exposed on the patient's body is placed into the catheter placement bag, and the first film and the second film are attached to the patient's skin surface for temporary adhesive fixation. Due to the material characteristics of the first film and the second film, the adsorption force with the skin is increased, so that there is no gap between the opening of the catheter placement bag and the patient's skin surface, thereby realizing the waterproof protection of the hemodialysis catheter when the patient takes a bath; the indication ring is a waterproof label that turns red when encountering water. If the first film and the second film are not firmly adhered to the patient's skin surface, resulting in a gap between the opening of the catheter placement bag and the patient's skin surface, the indication ring turns red when encountering water, reminding the patient to replace a new sleeve bag.

[0006] The advantages of the utility model compared with the prior art are as follows: 1) Tightly adhered and good waterproof effect: By selecting films made of specific materials, the adsorption force is enhanced, ensuring no gap between the sleeve bag and the patient's skin, effectively preventing water from seeping in, and protecting the hemodialysis catheter from being soaked by water;

[0007] 2) Intuitive indication for easy maintenance: The innovative design of the water-sensitive color-changing indicator ring enables patients to immediately detect the loose fitting of the sleeve bag during bathing, allowing them to take timely measures to avoid the risk of infection.

[0008] 3) Simple structure and convenient use: The sleeve bag adopts an integrated design with a simple structure and easy operation. Patients can complete the installation and replacement by themselves without the assistance of professional medical staff.

[0009] 4) Sterile and safe, reducing infection: The entire sleeve bag is made of sterile materials to ensure that it does not cause secondary infection to patients during use and improve the safety of treatment. Description of the Drawings

[0012] The following further elaborates on the present utility model in conjunction with the drawings.

[0013] Embodiment 1

[0014] As Figure 1 shown, the components of this product mainly include:

[0015] 1) First film 1

[0016] The first film 1 is a ring structure made of a soft and water-sensitive medical-grade material. This material has a certain adhesiveness in the dry state with strong adhesion force, enabling it to closely adhere to the patient's skin. The inner diameter of the first film 1 is slightly larger than the outer diameter of the indicator ring 2 to facilitate their tight connection.

[0017] 2) Indicator ring 2

[0018] The indicator ring 2 is a ring structure made of a special waterproof material that changes color when exposed to water. This material remains its original color, such as white, when not in contact with water, and quickly turns into a prominent red once it comes into contact with water, serving as an indication of waterproof failure. The inner diameter of the indicator ring 2 is slightly larger than the outer diameter of the second film 3, and the outer diameter is slightly smaller than the inner diameter of the first film 1 to ensure that the three can be nested layer by layer.

[0019] 3) Second film 3

[0020] Similar to the first film 1, the second film 3 is also a ring structure, but is usually located closer to the catheter placement bag 4. The inner diameter of the second film 3 is slightly larger than the outer diameter of the opening of the catheter placement bag 4 to ensure that it can tightly wrap around the opening edge.

[0021] 4) Catheter placement bag 4

[0022] The catheter placement bag 4 is a bag-like structure with one end closed and the other end open, made of a soft and breathable medical-grade material. Its opening edge is designed with a reinforcing layer to increase the connection strength with the film two 3. The space inside the bag is large enough to accommodate the dialysis catheter 5 and protect it from external contamination.

[0023] Embodiment Two

[0024] Based on Embodiment One, as Figure 1 shown, in terms of the connection method, the film one 1 and the indicating ring 2 are connected by nesting, that is, the inner diameter of the film one 1 is sleeved on the outer diameter of the indicating ring 2, and the two fit tightly without gaps. The indicating ring 2 and the film two 3 are also connected by nesting, and the inner diameter of the indicating ring 2 is sleeved on the outer diameter of the film two 3 to ensure that the three form a stable whole. The three can be integrally formed by injection molding.

[0025] Embodiment Three

[0026] Based on Embodiment Two, as Figure 1 shown, the main functions of this product include:

[0027] 1) Waterproof protection: Through the layer-by-layer protection of the film one 1, the indicating ring 2, and the film two 3, it is ensured that the dialysis catheter 5 is not immersed in water in humid environments such as bathing, reducing the risk of infection.

[0028] 2) Intuitive indication: The water-sensitive color-changing function of the indicating ring 2 can immediately reflect the waterproof state of the sleeve bag. Once water seeps in, it immediately turns red to remind the patient.

[0029] 3) Comfortable fit: All materials are selected as medical-grade soft materials to ensure that the skin of the patient will not be uncomfortable during use.

[0030] Embodiment Four

[0031] Based on Embodiment Three, as Figure 1 shown, the working principle of this product: When in use, tear off the surface disposable stickers of the film one 1 and the film two 3 and directly attach them to the skin at the catheter insertion site of the patient. When the indicating ring 2 encounters water, it turns red to remind the patient to replace the sleeve bag.

[0032] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
