Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to pressure ulcer patches. Background Technology
[0002] In clinical practice, when using infusion needles, it is necessary to use dressings to fix the needle handle in place for a long time to prevent the needle from slipping or rolling during use, which could affect the treatment of the patient.
[0003] However, existing dressings, when fixed in place, directly adhere the infusion needle handle to the patient's skin. Prolonged use of this can lead to pressure sores. Additionally, during infusion, the needle handle is also directly attached to the patient's hand, which increases the risk of pressure sores for patients requiring long-term infusion therapy, reducing patient comfort. Therefore, we proposed a pressure sore dressing to address the aforementioned issues. Utility Model Content
[0004] The purpose of this invention is to provide a pressure ulcer dressing to solve the problem mentioned in the background art, where existing dressings, when used for fixation, involve directly applying the infusion needle to the patient's skin, which can lead to pressure injuries after prolonged use.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure ulcer patch, comprising a patch, wherein a U-shaped adhesive piece is provided at the rear end of the patch, a sponge pad is provided on the upper surface of the patch, a first strip-shaped adhesive piece is provided at the rear end of one side of the patch, and a second strip-shaped adhesive piece is provided at the front end of the other side of the patch.
[0006] Preferably, the upper surfaces of the first strip-shaped adhesive sheet and the second strip-shaped adhesive sheet are provided with a first release paper, the lower surface of the end of the U-shaped adhesive sheet is provided with a second release paper, the lower surface of the patch is provided with a third release paper, and an adhesive layer is provided at the connection points between the first strip-shaped adhesive sheet, the second strip-shaped adhesive sheet, the U-shaped adhesive sheet, the patch and the first release paper, the second release paper, and the third release paper.
[0007] Preferably, the adhesive layer has a plurality of dot-like structures inside.
[0008] Preferably, the interior of the sponge pad is provided with several ventilation holes, which are arranged in a rectangular array.
[0009] Preferably, the front end of the patch is provided with a tear strip.
[0010] Preferably, the first strip-shaped bonding sheet, the second strip-shaped bonding sheet, the U-shaped bonding sheet, and the patch are all made of breathable non-woven fabric.
[0011] Preferably, the upper surface of the sponge pad is provided with an infusion needle placement area.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model provides a sponge pad on the upper surface of the patch. After application, the sponge pad provides better cushioning between the infusion needle and the patch, thus preventing pressure sores. This solves the problem that existing dressings, when fixed, directly adhere the infusion needle to the patient's skin, which can lead to pressure injuries after prolonged use.
[0014] 2. By setting a U-shaped adhesive patch and two sets of strip adhesive patches on the patch, after the infusion needle is inserted against the sponge pad, the two sets of second release paper at the end of the U-shaped adhesive patch can be removed first, and the U-shaped adhesive patch can be stretched to cover the upper surface of the needle handle laterally. The adhesive layer at the end is used to fix it to the side of the patch. Then, the first release paper on the two sets of strip adhesive patches is removed, and the two sets of strip adhesive patches are folded inward to be longitudinally bonded to the top of the U-shaped adhesive patch. The double bonding and fixation in both the transverse and longitudinal directions significantly improves the stability of the infusion needle fixation.
[0015] 3. The first strip-shaped adhesive sheet, the second strip-shaped adhesive sheet, the U-shaped adhesive sheet, and the patch of this utility model are all made of breathable non-woven fabric, and the sponge pad and the adhesive layer have several porous structures, which ensure the overall breathability of the structure and meet the needs of long-term use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1-4 An embodiment of this utility model is provided: a pressure ulcer patch, including a patch 1, a U-shaped adhesive piece 2 at the rear end of the patch 1, a sponge pad 3 on the upper surface of the patch 1, a first strip adhesive piece 5 at the rear end of one side of the patch 1, and a second strip adhesive piece 6 at the front end of the other side of the patch 1.
[0023] Please see Figure 1 , Figure 3 and Figure 4 The upper surfaces of the first strip-shaped adhesive sheet 5 and the second strip-shaped adhesive sheet 6 are provided with a first release paper 7, the lower surface of the end of the U-shaped adhesive sheet 2 is provided with a second release paper 9, and the lower surface of the patch 1 is provided with a third release paper 10. An adhesive layer 11 is provided at the connection between the first strip-shaped adhesive sheet 5, the second strip-shaped adhesive sheet 6, the U-shaped adhesive sheet 2, the patch 1 and the first release paper 7, the second release paper 9, and the third release paper 10. The release paper is used to protect the adhesive layer 11 when the first strip-shaped adhesive sheet 5, the second strip-shaped adhesive sheet 6, the U-shaped adhesive sheet 2, and the patch 1 are not in use, so as to prevent the adhesive layer 11 from being exposed and adhering to dust, which would reduce its stickiness.
[0024] Please see Figure 4 The adhesive layer 11 has several dot-shaped structures 12 inside. The dot-shaped structures 12 are free of glue, which can reduce the sensitization rate on the one hand, and make the adhesive layer 11 have a certain air permeability on the other hand.
[0025] Please see Figure 1 The sponge pad 3 has several ventilation holes 4 inside, and these ventilation holes 4 are arranged in a rectangular array, which gives the sponge pad 3 a certain degree of breathability.
[0026] Please see Figure 1 The front end of the patch 1 is provided with a tear strip 8, which can provide a force point when the patch 1 needs to be removed, so as to facilitate the removal of the patch 1.
[0027] Furthermore, the first strip-shaped bonding piece 5, the second strip-shaped bonding piece 6, the U-shaped bonding piece 2, and the patch 1 are all made of breathable non-woven fabric, which ensures the breathability of the patches after bonding.
[0028] Furthermore, the upper surface of the sponge pad 3 is provided with an infusion needle placement area, which is used to place the infusion needle and can provide a good cushioning effect after being attached and fixed, thus preventing pressure sores.
[0029] Working principle: In use, first peel off the third release paper 10 on the lower surface of patch 1 to expose the bottom adhesive layer 11. Use the adhesive layer 11 to attach patch 1 behind the puncture site. After that, attach the infusion needle handle to the sponge pad 3 on the surface of patch 1 to complete the puncture. Afterward, first peel off the two sets of second release papers 9 at the ends of the U-shaped adhesive patch 2, stretch the U-shaped adhesive patch 2 to cover the upper surface of the needle handle, and use the adhesive layer 11 at the ends to fix it to the side of patch 1. Finally, peel off the first release paper 9 from the first strip adhesive patch 5 and the second strip adhesive patch 6. The template 7 is used, and the first strip adhesive piece 5 and the second strip adhesive piece 6 are folded inward and longitudinally bonded to the top of the U-shaped adhesive piece 2 to improve the stability of the infusion needle fixation. After attachment, because there is a layer of sponge pad 3 between the infusion needle and the patch 1, it can play a good cushioning effect, thereby avoiding pressure sores. The first strip adhesive piece 5, the second strip adhesive piece 6, the U-shaped adhesive piece 2, and the patch 1 are all made of breathable non-woven gauze, and the sponge pad 3 and the adhesive layer 11 have several porous structures to ensure the overall breathability of the structure and meet the needs of long-term use.
