Description

Technical Field

[0001] The present application belongs to the field of medical device technology, and in particular, relates to a pressable patch. Background Art

[0002] During the infusion process, a dressing is usually used to fix the infusion needle or catheter to maintain its stable position on the skin and prevent it from shifting or falling off. This dressing is usually made of transparent, non-woven fabric, with a certain degree of air permeability and stickiness. It can effectively fix the infusion equipment without affecting the patient's activities, and it is also convenient for medical staff to observe the situation of the infusion site.

[0003] However, after the needle falls off or is pulled out, bleeding is likely to occur. A blood-swelling material may be provided between the patch and the puncture point. The blood-swelling material expands after absorbing blood, thereby squeezing the puncture point to achieve the purpose of stopping bleeding. However, in actual use, the flowing blood is likely to flow between the patch and the skin, thereby reducing the adhesion of the patch and failing to achieve a good pressing hemostasis effect. Utility Model Content

[0004] The utility model aims to provide a pressable dressing, aiming to improve the pressing hemostasis effect of the dressing.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a pressable patch, which includes an adhesive layer, a fixing layer, a cotton layer and a blood-absorbing expansion layer, the adhesive layer having an adhesive surface for sticking to the skin and a through hole for being arranged corresponding to the puncture point; the fixing layer is located on the side of the adhesive layer facing away from the adhesive surface, and the periphery of the fixing layer is fixedly connected to the adhesive layer to form a accommodating cavity between the adhesive layer and the fixing layer; the cotton layer is arranged in the accommodating cavity, and the cotton layer covers the through hole; the blood-absorbing expansion layer is located in the accommodating cavity, and the blood-absorbing expansion layer is located between the fixing layer and the cotton layer.

[0006] Optionally, the blood-absorbing expansion layer includes at least one of a high-expansion sponge layer and a high-molecular blood-absorbing resin layer.

[0007] Optionally, a hemostatic drug is provided in the blood-absorbing expansion layer.

[0008] Optionally, the peripheral edge of the blood-absorbent expansion layer protrudes beyond the peripheral side of the cotton layer.

[0009] Optionally, the connection position between the fixing layer and the adhesive layer is spaced apart from the periphery of the cotton layer.

[0010] Optionally, the distance between the connection position of the fixing layer and the adhesive layer and the periphery of the cotton layer ranges from 2 mm to 3 mm.

[0011] Optionally, the pressable patch also includes an elastomer and a tape, the elastomer and the fixing layer are on the side facing away from the adhesive layer, the tape is adhered to the surface of the elastomer facing away from the fixing layer, and both ends of the tape can be adhered to the skin.

[0012] Optionally, the elastomer is a silicone body.

[0013] Optionally, the elastomer and the fixing layer are an integral structure.

[0014] Optionally, the ends of the tape may be folded over.

[0015] The above one or more technical solutions in the pressable patch provided by the utility model have at least one of the following technical effects: when in use, the adhesive surface of the adhesive layer is adhered to the skin at the puncture site, and the cotton layer covers the puncture point through the through hole. In the case of bleeding at the puncture point, the blood can flow through the cotton layer to the blood-absorbing expansion layer. After the blood-absorbing expansion layer absorbs blood and expands, it presses the puncture point to achieve the effect of stopping bleeding; and in this process, the blood flows through the through hole to the side of the adhesive layer facing away from the adhesive surface. In addition, the periphery of the through hole can also fit tightly with the skin, so that the blood does not easily flow into the gap between the adhesive layer and the skin. The adhesive layer has good adhesive reliability. At the same time, the blood-absorbing expansion layer is clamped and fixed by the fixing layer and the adhesive layer. The fixing effect of the blood-absorbing expansion layer is good, and the pressing effect after blood-absorbing expansion is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following combination Figures 1 to 4 The compressible patch 100 according to the embodiment of the present application is described.

[0034] like Figures 1 to 3As shown, in one embodiment of the present application, a pressable dressing 100 is provided, which includes an adhesive layer 110, a fixing layer 120, a cotton layer 130 and a blood-absorbing expansion layer 140: the adhesive layer 110 has an adhesive surface 111 for being adhered to the skin and a through hole 112 for being arranged corresponding to the puncture point; the fixing layer 120 is located on the side of the adhesive layer 110 facing away from the adhesive surface 111, and the periphery of the fixing layer 120 is fixedly connected to the adhesive layer 110 to form a receiving cavity 121 between the adhesive layer 110 and the fixing layer 120; the cotton layer 130 is arranged in the receiving cavity 121, and the cotton layer 130 covers the through hole 112; the blood-absorbing expansion layer 140 is located in the receiving cavity 121, and the blood-absorbing expansion layer 140 is located between the fixing layer 120 and the cotton layer 130.

[0035] The adhesive layer 110 may refer to the part of the patch that is pasted on the skin. The adhesive layer 110 may be made of transparent plastic or non-woven fabric. An adhesive is provided on one side of the adhesive layer 110, and the patch is fixed by adhering to the skin through the adhesive. The surface of the adhesive layer 110 covered with the adhesive is the adhesive layer 110. After the adhesive layer 110 is pasted on the skin, a through hole 112 is provided at a position of the adhesive layer 110 corresponding to the puncture point, and the through hole 112 allows the adhesive layer 110 to be exposed outside the puncture point. The puncture point may be the position where the needle tip is inserted into the skin.

[0036] The fixing layer 120 may refer to a component used to fix the cotton layer 130 and the blood-absorbing expansion layer 140. The fixing layer 120 and the adhesive layer 110 form a double-layer structure. The fixing layer 120 is located on the side of the fixing layer 120 that is away from the adhesive surface 111. The periphery of the fixing layer 120 is fixedly connected to the adhesive layer 110, so that a space can be formed between the middle part of the fixing layer 120 and the fixing layer 120. The space is the accommodating cavity 121. The periphery of the fixing layer 120 can be fixedly connected to the adhesive layer 110 by hot pressing or bonding.

[0037] The cotton layer 130 may refer to a component made of cotton. The cotton layer 130 may be a sterile cotton pad. The cotton layer 130 covers the through hole 112. The area of ​​the cotton layer 130 is larger than the area of ​​the through hole 112, so that the cotton layer 130 is not easy to escape from the through hole 112 and is fixed in the accommodating cavity 121. The edge of the cotton layer 130 may also be bonded or hot-pressed to the adhesive layer 110 to achieve a more stable fixation of the cotton layer 130.

[0038] The blood-absorbing expansion layer 140 may be made of a material that absorbs and expands. The blood-absorbing expansion layer 140 is located in the accommodating cavity 121 and between the cotton layer 130 and the fixing layer 120. After bleeding from the puncture point, the blood can flow through the cotton layer 130 to the blood-absorbing expansion layer 140. The blood-absorbing expansion layer 140 expands after absorbing blood. The expanded blood-absorbing expansion layer 140 can squeeze the puncture point, thereby achieving the effect of pressing to stop bleeding. The blood-absorbing expansion material may be, but is not limited to, a sponge, a water-absorbing resin, or a water-absorbing sponge.

[0039] When the pressable patch 100 of the embodiment of the present application is used, the adhesive surface 111 of the adhesive layer 110 is adhered to the skin at the puncture site, and the cotton layer 130 covers the puncture site through the through hole 112. In the case of bleeding at the puncture site, the blood can flow through the cotton layer 130 to the blood-absorbing expansion layer 140. After the blood-absorbing expansion layer 140 absorbs blood and expands, it presses the puncture site to achieve the effect of stopping bleeding. In this process, the blood flows through the through hole 112 to the side of the adhesive layer 110 facing away from the adhesive surface 111. In addition, the periphery of the through hole 112 can also fit closely with the skin, so that the blood does not easily flow between the adhesive layer 110 and the skin. The adhesive layer 110 has good adhesive reliability. At the same time, the blood-absorbing expansion layer 140 is clamped and fixed by the fixing layer 120 and the adhesive layer 110. The fixing effect of the blood-absorbing expansion layer 140 is good, and the pressing effect after swelling by blood is better.

[0040] In some embodiments, an ear piece 113 is connected to the side of the adhesive layer 110 , and the adhesive layer 110 can be easily torn off from the skin by pulling the ear piece 113 .

[0041] In another embodiment of the present application, the blood-absorbing expansion layer 140 includes at least one of a high-expansion sponge layer and a high-molecular blood-absorbing resin layer.

[0042] The high expansion sponge layer may refer to a component made of high expansion sponge, such as PVA sponge and PVF sponge.

[0043] The high molecular blood-absorbing resin may refer to a component made of the high molecular blood-absorbing resin.

[0044] The blood-absorbing expansion layer 140 is a single-layer structure, that is, the blood-absorbing expansion layer 140 is a high-expansion sponge layer or a high-molecular blood-absorbing resin layer, or the blood-absorbing expansion layer 140 is a double-layer structure, and the blood-absorbing expansion layer 140 includes a stacked high-expansion sponge layer and a high-molecular blood-absorbing resin layer.

[0045] By adopting the technical solution of this embodiment, the high expansion sponge layer and the high molecular blood-absorbing resin layer can absorb a large amount of blood and expand, and have a good hemostatic effect when pressed.

[0046] In another embodiment of the present application, a hemostatic drug is disposed in the blood-absorbing expansion layer 140 .

[0047] By adopting the technical solution of this embodiment, hemostatic drugs are added into the blood-absorbing expansion layer 140. After the blood-absorbing expansion layer 140 absorbs blood, the hemostatic drugs can release their medicinal properties, thereby accelerating hemostasis.

[0048] In another embodiment of the present application, see Figure 3 As shown, the peripheral edge of the blood-absorbent expansion layer 140 protrudes beyond the peripheral side of the cotton layer 130 .

[0049] The area of ​​the blood-absorbent expansion layer 140 is larger than the area of ​​the cotton layer 130 , so that the blood-absorbent expansion layer 140 can completely cover the cotton layer 130 .

[0050] By adopting the technical solution of this embodiment, the blood-absorbing expansion layer 140 has a large area, a large blood absorption amount, a large volume after expansion, a large pressing hemostatic force, and a good hemostatic effect; in addition, the area after expansion is large, the pressing area is large, and the hemostatic effect is better.

[0051] In another embodiment of the present application, see Figure 3 As shown, the connection position between the fixing layer 120 and the adhesive layer 110 is spaced apart from the periphery of the cotton layer 130 .

[0052] There is a certain distance between the periphery of the fixing layer 120 and the periphery of the cotton layer 130 , thereby forming a space which is arranged around the cotton layer 130 .

[0053] By adopting the technical solution of this embodiment, the space formed between the periphery of the fixing layer 120 and the periphery of the cotton layer 130 can allow the blood-absorbing expansion layer 140 to expand toward the periphery, thereby facilitating increasing the area of ​​the blood-absorbing expansion layer 140, increasing the pressing area, and improving the hemostatic effect.

[0054] In another embodiment of the present application, see Figure 3 As shown, the distance between the connection position of the fixing layer 120 and the adhesive layer 110 and the periphery of the cotton layer 130 is in the range of 2 mm to 3 mm.

[0055] The spacing H between the connection position of the fixing layer 120 and the adhesive layer 110 and the periphery of the cotton layer 130, wherein 2mm≤H≤3mm, the value of H can be 2mm, 3mm, and any value between 2mm and 3mm. For example, the value of H can be but is not limited to 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, and 3mm.

[0056] 2mm≤H≤3mm. It can be understood that the design of H≥2mm can ensure that the space formed between the periphery of the fixing layer 120 and the periphery of the cotton layer 130 is not too small, and the blood-absorbing expansion layer 140 can expand a certain distance toward the circumference to increase the pressing area; the design of H≤3mm can ensure that the expansion distance of the fixing layer 120 toward the circumference is not too large, and the blood-absorbing expansion layer 140 has a better pressing force and pressing effect on the puncture point.

[0057] By adopting the technical solution of this embodiment, a good pressing effect is achieved on the puncture point.

[0058] In another embodiment of the present application, see Figure 3 and Figure 4 As shown, the pressable patch 100 also includes an elastomer 150 and a tape 160. The elastomer 150 and the fixing layer 120 are on the side facing away from the adhesive layer 110. The tape 160 is adhered to the surface of the elastomer 150 facing away from the fixing layer 120. Both ends of the tape 160 can be adhered to the skin.

[0059] The elastic body 150 may refer to a component having elasticity, and the material of the elastic body 150 may be but is not limited to silicone, rubber, etc.

[0060] The tape 160 may be a component that can be adhered to the skin, and the tape 160 is attached to the elastic body 150; the blood-absorbing expansion layer 140, the fixing layer 120, the elastic body 150 and the tape 160 are stacked in sequence. The tape 160 may be, but is not limited to, a non-woven tape, a transparent tape, or an elastic binding tape.

[0061] By adopting the technical solution of this embodiment, when bleeding is heavy or after the needle is removed, the two ends of the tape 160 can be adhered to the skin, thereby pressing the elastomer 150 against the puncture point, increasing the pressing force and improving the hemostatic effect; in addition, after the needle is removed, the patient does not need to press the puncture point with his hands, which is convenient for the patient to move.

[0062] In another embodiment of the present application, the elastomer 150 is a silicone body.

[0063] By adopting the technical solution of this embodiment, the elastic body 150 is made of silicone material, and silicone has good elasticity and good hemostatic effect when pressed.

[0064] In another embodiment of the present application, the elastic body 150 and the fixing layer 120 are an integral structure.

[0065] The elastic body 150 and the fixing layer 120 are an integral structure formed by an integral molding process such as injection molding or 3D printing.

[0066] By adopting the technical solution of this embodiment, the production process can be reduced and the production cost can be saved; the elastic body 150 can connect the tape 160 and the fixing layer 120 together, and the use of the patch is more convenient.

[0067] In another embodiment of the present application, both ends of the adhesive tape 160 are foldable.

[0068] By adopting the technical solution of this embodiment, the two ends of the tape 160 can be folded. When applying a fixed needle or catheter, the two ends of the tape 160 can be in a folded state, so that the volume of the application is small and it is more convenient to use. After the needle is removed, the two ends of the tape 160 can be unfolded to stick to the skin, thereby squeezing the elastomer 150 to press the puncture point, thereby increasing the pressing force and improving the hemostatic effect. The patient does not need to press the puncture point with his hands, which is convenient for the patient to move.

[0069] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.
