[0001] This utility model relates to the field of waterproof semi-implantable IDDS wound dressing technology, and in particular to a waterproof semi-implantable IDDS wound dressing device. Background Technology

[0002] 10% to 20% of cancer patients develop refractory cancers, severely impacting their quality of life. When oral analgesia is ineffective, the NCCN Cancer Pain Guidelines recommend intrathecal drug delivery systems (IDDS) for pain relief. An IDDS consists of an infusion pump and a connecting thin catheter. The infusion pump delivers medication directly into the cerebrospinal fluid surrounding the brain and spinal cord, bypassing the blood-brain barrier to deliver drugs to the central nervous system. IDDS are available in fully implantable and semi-implantable versions. Due to the high cost of fully implantable devices, they are not currently covered by medical insurance; therefore, semi-implantable devices are more common in clinical practice.

[0003] A semi-implantable IDDS consists of an implantable infusion port, a catheter, and ancillary devices[4]. The infusion port of a semi-implantable IDDS is usually located in the lower left or lower right abdomen of the patient. Then, a butterfly needle is inserted into the infusion port placed in the lower left or lower right abdomen of the patient, the catheter is connected, analgesic drugs are pumped in, and finally, sterile gauze and transparent dressing are used to cover the port to keep it clean and dry and prevent infection.

[0004] Although the patient's abdomen was covered with a waterproof transparent dressing, the dressing was prone to curling, seeping water, and falling off during the bath, which could lead to redness and inflammation of the skin around the puncture site, and in severe cases, intracranial infection. Utility Model Content

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0040] Reference Figure 1-5 The semi-implantable IDDS waterproof wound dressing device shown includes:

[0041] Silicone sticker 100;

[0042] The voltage regulating component 200 is wrapped inside the silicone pad 100 and extends to the outside of the silicone pad 100;

[0043] Water-resistant flange 300 is bonded to the outer edge of silicone sticker 100.

[0044] In use, firstly, the water-blocking flange 300 is bonded to the outer edge of the pressure regulating component 200. Then, the pressure regulating component 200 is squeezed to compress and store force. The silicone patch 100 is then placed over the outside of the semi-implantable IDDS and the transparent dressing. Finally, the force on the pressure regulating component 200 is released, and the stress on the pressure regulating component 200 is released, creating negative pressure by drawing air out between the silicone patch 100 and the patient's skin.

[0045] During disassembly, press the pressure regulating component 200 to store force and restore the air pressure between the silicone patch 100 and the patient's skin to atmospheric pressure. Then, remove the silicone patch 100 from the semi-implantable IDDS and transparent dressing.

[0046] The silicone patch 100 adheres to the patient's skin due to its self-adhesive properties. The pressure regulating component 200 creates negative pressure between the silicone patch 100 and the patient's skin, increasing the adhesion of the silicone patch 100 and preventing the patient from accidentally touching it during cleaning, which could cause the silicone patch 100 to fall off. At the same time, the pressure regulating component 200 can also adjust the negative pressure between the silicone patch 100 and the patient's skin, allowing the silicone patch 100 to be easily removed, cleaned, and reused.

[0047] The water-resistant flange 300 blocks water from entering the silicone patch 100, effectively preventing the transparent dressing covering the butterfly needle from curling, seeping, or falling off, thus preventing infection.

[0048] In some embodiments of this utility model, in order to ensure the proper installation of the voltage regulating component 200, refer to Figure 5 As shown, a binding sleeve 110 is provided at the center of the outer side of the silicone patch 100, and a blocking edge 120 is provided at the opening of the binding sleeve 110 away from the silicone patch 100. A through hole 130 communicating with the pressure regulating component 200 is provided at the center of the silicone patch 100.

[0049] When installing the pressure regulating component 200, the blocking edge 120 is opened and the pressure regulating component 200 is installed inside the edge sleeve 110, so that the pressure regulating component 200 corresponds to the through hole 130.

[0050] The edging sleeve 110 and the blocking edge 120 provide space for the installation of the pressure regulating assembly 200.

[0051] The through-hole 130 allows the pressure regulating component 200 to properly extract air between the silicone patch 100 and the patient's skin.

[0052] In some embodiments of this utility model, in order to maintain a seal with the edge-sealing sleeve 110, refer to Figure 2 and Figure 3 As shown, the voltage regulating assembly 200 includes:

[0053] The outer casing 210 is enclosed inside the binding sleeve 110;

[0054] The first sealing ring 220 is bonded to the outer side of the outer shell 210 and contacts the inner surface of the edge sleeve 110;

[0055] There are two baffle plates 230, which are detachably fixed to the openings at both ends of the housing 210, and the baffle plates 230 are circular.

[0056] Sliding assembly 240 is installed inside housing 210.

[0057] In use, pressure is first applied to the sliding component 240 to make it slide and compress the energy storage structure, simultaneously expelling air from inside the outer shell 210. After the silicone patch 100 is applied to the skin, the pressure on the sliding component 240 is released, and the energy storage structure pushes the sliding component 240 back to its original position, extracting air from between the silicone patch 100 and the skin. For removal, the sliding component 240 is squeezed again to push the air from inside the outer shell 210 into the space between the silicone patch 100 and the skin.

[0058] The outer shell 210 supports the edge banding 110 and provides space for the sliding component 240 to slide.

[0059] The first sealing ring 220 ensures the airtightness between the outer shell 210 and the edge sleeve 110, preventing gas from entering or leaking from the connection between the outer shell 210 and the edge sleeve 110.

[0060] Specifically, the sliding component 240 is blocked by the blocking plate 230, thereby limiting the sliding range of the sliding component 240.

[0061] In some embodiments of this utility model, in order to adjust the air pressure between the silicone patch 100 and the skin, refer to Figure 2 and Figure 3 As shown, the sliding component 240 includes:

[0062] Sliding plate 241 is slidably installed inside housing 210;

[0063] The second sealing ring 242 is bonded to the outside of the sliding plate 241 and contacts the inner surface of the housing 210.

[0064] Extension rod 243 is fixed on sliding plate 241 and passes through blocking plate 230;

[0065] Control button 244 is fixed to the end of extension rod 243 away from sliding plate 241.

[0066] In this process, the air between the silicone patch 100 and the skin is extracted by sliding the sliding plate 241, which will push the air into the space between the silicone patch 100 and the skin.

[0067] The second sealing ring 242 is used to seal the sliding plate 241 and the outer shell 210, preventing gas leakage or entry when the sliding plate 241 slides.

[0068] The extension rod 243 and the control button 244 work together to enable the sliding plate 241 to slide under external pressure, thus realizing the function of the sliding plate 241.

[0069] In some embodiments of this utility model, in order to push the sliding plate 241 to reset, refer to Figure 2 and Figure 3 As shown, a compression spring 250 is installed between the sliding plate 241 and the blocking plate 230. The compression spring 250 is compressed and stores force when the sliding plate 241 slides.

[0070] The spring 250 is compressed and stores force when the sliding plate 241 slides, and pushes the sliding plate 241 to reset after the squeezing force on the control button 244 disappears.

[0071] In some embodiments of this invention, to further prevent water from entering, refer to Figure 2 and Figure 4 As shown, the water-blocking flange 300 includes:

[0072] Water-blocking strip 310 is disposed at the outer edge of pressure regulating component 200;

[0073] Adhesive pad 320, with its two sides respectively bonded to water-blocking strip 310 and silicone sticker 100.

[0074] The adhesive pad 320 ensures the proper installation and use of the water-blocking strip 310 and provides initial water-blocking protection.

[0075] In some embodiments of this utility model, reference is made to Figure 1 As shown, silicone sticker 100 is a pure silicone product with high self-adhesion.

[0076] Among them, the silicone patch 100 can adhere to the patient's skin by its own effect, ensuring stability while also playing a role in preventing water.

[0077] The working method of this utility model:

[0078] In use, first, attach the water-blocking strip 310 to the outer edge of the silicone patch 100 via the adhesive pad 320. Then, squeeze the control button 244 to push the sliding plate 241 to slide and expel the air inside the outer shell 210, and squeeze the compression spring 250 to compress and store force. Then, cover the outside of the semi-implantable IDDS and transparent dressing with the silicone patch 100. Then, release the pressure on the control button 244, and the elastic force of the compression spring 250 will be released, pushing the sliding plate 241 to reset and drawing out the air between the silicone patch 100 and the patient's skin to form a negative pressure.

[0079] During disassembly, press the control button 244 to push the sliding plate 241 to slide, pushing the air inside the outer shell 210 into the space between the silicone patch 100 and the patient's skin. Then, remove the silicone patch 100.
