Description

Technical Field

[0001] This utility model relates to medical auxiliary devices, and more particularly to a PICC waterproof sleeve with adjustable support position. Background Technology

[0002] Peripherally inserted central catheters (PICCs) can meet various patient needs, including the infusion of highly irritating drugs, high-concentration fluids, rapid fluid replacement, and long-term treatment. Due to their long indwelling time and reduced pain from repeated punctures, they are popular with both patients and nurses in clinical practice. To maintain the normal function and safe use of the PICC catheter, the exposed portion of the catheter and its dressing must be kept clean and dry, especially avoiding contact with water, otherwise it can easily lead to dislodgement or infection. While PICC catheters offer convenience, bathing becomes very inconvenient, especially in summer, when it is often impossible for patients to bathe independently.

[0003] Existing waterproof sleeves are all made of soft silicone, which brings two main problems: (1) In a natural state, the silicone sleeve will collapse under gravity and adhere to the skin of the arm. However, there are needles or catheters left at the puncture sites on the arm. During daily activities, the silicone sleeve will frequently touch the needles or catheters, causing discomfort at the puncture site. (2) The silicone sleeve is soft and requires manual pulling of the cuffs piece by piece when wearing it, which involves many pulls. Moreover, pulling one side will pull the other side. For example, pulling the sleeve on the inside of the arm will cause the sleeve on the outside of the arm to be close to the skin. Due to the natural properties of silicone, there is a large friction with the skin. Therefore, when pulling, the skin will also be pulled, causing discomfort and making it inconvenient to wear. Utility Model Content

[0004] The purpose of this invention is to provide a PICC waterproof sleeve with adjustable support position to solve the problems existing in the prior art.

[0005] The present invention provides a PICC waterproof sleeve with adjustable support position, comprising an integrally formed silicone sleeve; an internal cavity of the silicone sleeve for inserting into the patient's arm; and a cuff at each end of the silicone sleeve connecting to the cavity; wherein the end closer to the palm is the second cuff, and the end closer to the elbow is the first cuff.

[0006] An inner ring is provided in the cavity and near the first cuff, and an outer ring is provided outside the silicone sleeve;

[0007] The outer ring has an inner buckle tooth on its inner side and an outer buckle tooth on its outer side; the outer ring and the inner ring are fastened together by matching buckle teeth, and the silicone sleeve is fastened between the buckle teeth.

[0008] The outer ring is provided with several protruding ribs, the extension direction of which points to the cuffs at both ends, and each protruding rib is distributed at equal distances along the outer ring.

[0009] Both the outer and inner rings are made of plastic material.

[0010] The PICC waterproof sleeve with adjustable support position described in this utility model has the advantage that by simultaneously fastening the inner and outer rings to evenly fasten a cross-section of the silicone sleeve, the inner and outer rings work together to achieve two functions and solve two problems in the prior art: (1) The inner ring acts as a continuous support component, greatly reducing the chance of the silicone sleeve coming into contact with the indwelling needle or catheter, thus improving human comfort. (2) When wearing, the outer ring can be used as a handhold to evenly pull the silicone sleeve upwards, avoiding discomfort from pulling body hair. It also improves pulling efficiency and makes wearing more convenient. Attached Figure Description

[0016] 10-Outer ring, 11-Protruding rib; 20-Silicone sleeve, 21-First cuff, 22-Second cuff; 30-Inner ring. Detailed Implementation

[0017] like Figures 1 to 4 As shown, the PICC waterproof sleeve with adjustable support position described in this utility model includes an integrally formed silicone sleeve 20; the internal cavity of the silicone sleeve 20 is used to insert into the patient's arm; each end of the silicone sleeve 20 is provided with a cuff that connects to the cavity; wherein the end closer to the palm is the second cuff 22, and the end closer to the elbow is the first cuff 21.

[0018] An inner ring 30 is provided in the cavity and close to the first cuff 21, and an outer ring 10 is provided outside the silicone sleeve 20;

[0019] The outer ring 10 has an inner buckle tooth on its inner side, and the inner ring 30 has an outer buckle tooth on its outer side; the outer ring 10 and the inner ring 30 are fastened together by matching buckle teeth, and the silicone sleeve 20 is fastened between the buckle teeth.

[0020] The outer ring 10 is provided with a number of protruding ribs 11 on its outer side. The extension direction of the protruding ribs 11 points to the cuffs at both ends, and each protruding rib 11 is distributed at equal distances along the outer side of the outer ring 10.

[0021] Both the outer ring 10 and the inner ring 30 are made of plastic material.

[0022] The working principle of the PICC waterproof sleeve with adjustable support position described in this utility model is as follows:

[0023] First, insert the inner ring 30 into the silicone sleeve 20, aligning the axial direction of the inner ring 30 with the axial direction of the silicone sleeve 20.

[0024] Then, adjust the position of the inner ring 30 within the silicone sleeve 20 according to the specific location where the patient requires maximum space support. Place the outer ring 10 over the outside of the silicone sleeve 20 and fasten it around the inner ring 30, clamping the silicone sleeve 20 between the outer ring 10 and the inner ring 30.

[0025] Finally, insert the patient's hand through the first cuff 21 and then pull it out through the second cuff 22, so that the inner ring 30 is positioned precisely to provide maximum support. The outer ring 10 acts as a gripper when the patient's arm passes through the cavity, improving ease of donning. After donning, the inner ring 10 provides permanent support, minimizing the chance of accidental contact with indwelling needles, catheters, etc.

[0026] The convex rib 11 can increase the friction when gripping.

[0027] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
