Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, and in particular to a waterproof dressing specifically designed for connecting highly waterproof drainage tubes to external wounds. Background Technology

[0002] Waterproof dressings for connecting drainage tubes to wounds are medical dressings specifically designed to fix and protect the area where the drainage tube protrudes from the skin. Their core function is to ensure a stable connection of the drainage tube while effectively protecting the wound from moisture and bacteria, promoting healing, and reducing the risk of infection.

[0003] A catheter fixation patch, as disclosed in Chinese Patent Publication No. CN114247032A, includes a fixation patch body, a limiting seal, a hydrocolloid dressing layer, and a protective layer. The fixation patch body has first connecting material layers at both ends of its front side, and a catheter placement seat at the center of its front side. The limiting seal corresponds to the shape of the fixation patch body, and a second connecting material layer is provided at both ends of one side of the limiting seal, corresponding to the positions of the first connecting material layers. The first and second connecting material layers are detachably connected. The hydrocolloid dressing layer is located on the reverse side of the fixation patch body. The surface of the hydrocolloid dressing layer has a first adhesive material layer that can adhere to human skin. The protective layer is detachably connected to the hydrocolloid dressing layer through the first adhesive material layer. This invention has a simple structure, low cost, is easy to use, saves time, and is firmly and reliably fixed, effectively reducing unplanned catheter removal and complications. However, this patent has the following problems: While the drainage tubes inserted into the patient's body can effectively fix the drainage tube in place, they cannot maintain a tight seal at the wound site. The drainage tube often needs to remain in the patient's body for a certain period of time. During this time, when the patient needs to clean the wound, the poor seal makes it easy for water to get in and cause infection, which can lead to a series of complications. Summary of the Invention

[0004] The purpose of this invention is to provide a special waterproof dressing for connecting a highly waterproof drainage tube to a wound, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waterproof dressing specifically for connecting a highly waterproof drainage tube to a wound on the body surface, comprising a drainage tube, and further comprising: The drainage tube clamp is made of medical-grade silicone material and has a certain degree of deformability. The front of the drainage tube clamp has a first opening, and the drainage tube is sleeved and installed inside the drainage tube clamp. The width of the first opening is smaller than the outer diameter of the drainage tube.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0019] Example 1 A highly waterproof drainage tube-specific waterproof dressing for connecting to external wounds, comprising a drainage tube, and further comprising: The drainage tube clamp 1 is made of medical silicone material and has a certain degree of deformability. The drainage tube clamp 1 has a first opening on the front and the drainage tube is fitted into the drainage tube clamp 1. The width of the first opening is smaller than the outer diameter of the drainage tube. Sealing wrapping tape 2, one end of sealing wrapping tape 2 is fixedly installed on the outer wall of drainage tube clamp 1, sealing wrapping tape 2 is used to wrap drainage tube clamp 1 and drainage tube; Absorbent dressing 3 is fixedly installed on the lower edge of drainage tube clamp 1. The diameter of the opening in the middle of the absorbent dressing 3 is the same as the inner diameter of the drainage tube clamp 1. Waterproof adhesive tape 4 is fixedly installed on the absorbent dressing 3 and extends outwards.

[0020] In this implementation scheme, through the opening on the drainage tube clamp 1, and since the entire drainage tube clamp 1 is made of medical-grade silicone, the drainage tube clamp 1 can be pried open from the opening, allowing the drainage tube to be inserted into the drainage tube clamp 1 through the enlarged opening. Then, the drainage tube clamp 1 needs to be slid down along the drainage tube, so that the absorbent dressing 3 at the lower end of the drainage tube clamp 1 adheres to the patient's skin. The opening of the drainage tube clamp 1 is manually pinched closed, ensuring the drainage tube is completely enclosed inside the drainage tube clamp 1. Two sealing wrapping tapes are then used. Wrap the end of the dressing around the drainage tube clamp 1 once, and use sealing tape 2 to keep the opening of the drainage tube clamp 1 closed. Then, spiral the sealing tape 2 upwards to seal the gap between the upper end of the drainage tube clamp 1 and the drainage tube, and fix the drainage tube and the drainage tube clamp 1 together. Finally, use waterproof adhesive tape 4 to adhere the absorbent dressing 3 along with the drainage tube clamp 1 to the patient's skin. Cover the wound and surrounding skin with the waterproof adhesive tape 4, and gently press the edges with your palm for 30 seconds to ensure that the adhesive layer fully adheres to the skin. The waterproof adhesive tape 4 will wrap the patient's skin around the drainage tube, while the absorbent dressing 3 will come into direct contact with the skin near the wound. First, it avoids the glue directly irritating the patient's wound. Second, it can absorb the fluids that overflow from the wound and keep the area around the wound dry. Compared with traditional wound dressings, it keeps the drainage tube wound sealed, allowing the patient to shower or take a bath normally. However, the duration of use should not be too long at a time.

[0021] Example 2 The drainage tube clamp 1 has a bending groove 101 at the rear. The bending groove 101 is used to bend the drainage tube clamp 1 to a large extent. The sealing wrapping tape 2 is spiral in shape. The whole is made of medical polyurethane film and the inner wall is coated with medical adhesive.

[0022] In this embodiment, the bending groove 101 allows the drainage tube clamp 1 to bend over a wide range, enabling the drainage tube to be inserted into the drainage tube clamp 1 from the opening, while the sealing wrapping tape 2 rotates spirally. Figure 1 As shown, the sealing wrapping tape 2 can then wrap around the drainage tube clamp 1 and the drainage tube, and the adhesive makes the sealing wrapping tape 2 have adhesive ability.

[0023] Example 3 The absorbent dressing 3 has a second opening with the same width as the first opening. The waterproof adhesive tape 4 has a third opening with a width smaller than the second opening. The waterproof adhesive tape 4 and the sealing wrapping tape 2 are covered with a release film.

[0024] In this implementation scheme, the drainage tube can pass through the second and third openings. After the first opening is closed, the second and third openings will also close. The width of the third opening is smaller than that of the second opening, and the edges of the third opening can be covered together to ensure that the waterproof adhesive 4 forms a sealed ring, ensuring that the waterproof adhesive 4 adheres to the patient's skin and ensuring the sealing of the wound on the patient's body surface.

[0025] The working principle and usage procedure of this invention are as follows: The drainage tube clamp 1 can be pried open from the opening, allowing the drainage tube to be inserted into the clamp 1 through the enlarged opening. Then, the clamp 1 is slid down along the drainage tube, ensuring the absorbent dressing 3 at the lower end of the clamp 1 adheres to the patient's skin. The opening of the clamp 1 is manually pinched closed to ensure complete sealing. Sealing tape 2 is wrapped around the clamp 1 from end to end, keeping the opening closed. The sealing tape 2 is then spirally wound upwards to seal the gap between the upper end of the clamp 1 and the drainage tube. A waterproof adhesive dressing 4 is then smoothly applied to the wound and surrounding skin, and the edges are gently pressed 30 degrees with the palm of the hand. In seconds, the adhesive layer fully adheres to the skin, and the waterproof adhesive tape 4 wraps around the patient's skin around the drainage tube. The absorbent dressing 3, along with the drainage tube clamp 1, is then adhered to and covered on the patient's skin through the waterproof adhesive tape 4, thus completing the fixation of the drainage tube and the sealing of the wound.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
