Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable micro-pressure micro-airbag hemostatic patch. Background Art

[0002] After the patient has finished intravenous infusion or arterial / venous blood sampling treatment, in order to stop bleeding at the puncture site as soon as possible, the nurse will usually ask the patient to press the puncture site with a cotton swab after the needle is removed to achieve the purpose of hemostasis. However, patients with poor coagulation function need to press for a long time. For patients with large bleeding, blood may penetrate the cotton swab. Excessive pressing can also cause local tissue damage or congestion. Especially for cancer patients, frequent arterial and vein punctures are required for treatment or examination during the recovery process. In order to better protect the patient's blood vessels, reduce the hematoma rate after pressing, relieve pain, and more conveniently compress and stop bleeding, a hemostatic patch is needed to assist in pressing.

[0003] Common hemostatic patches are shown in the invention patent with application number 201710898410.6: Hemostatic cotton patch. The hemostatic cotton patch includes fixing glue and hemostatic cotton. A hemostatic sheet is provided on the hemostatic cotton. The hemostatic sheet is in a low-temperature state and is flat and thin when not in use. When the hemostatic sheet covers the puncture site, the heat of the skin and blood causes the hemostatic sheet to expand rapidly. At this time, the pressure of the hemostatic sheet on the puncture site gradually increases, forming a certain pressure on the puncture site to prevent bleeding from the wound.

[0004] The prior art has the following defects: the above-mentioned hemostatic patch is made of a single hemostatic material, and mainly uses the hemostatic patch to perform local compression on the puncture site to stop bleeding. The overall shape of the hemostatic patch is mostly "single-line" shaped. The "single-line" hemostatic patch only has a force in one direction on the patient's puncture site, and medical staff and patients cannot promptly judge whether the pressure is in a suitable state. For patients with poor coagulation function or patients with a large amount of bleeding, the local pressure of the hemostatic patch and the pressure in one direction of the hemostatic patch cannot effectively compress and stop bleeding. At the same time, the hemostatic patch only has a force in one direction on the patient's puncture site, which can easily cause concentrated pressure at the wound site, and easily form bruises, redness and swelling at the puncture site, which is not conducive to the recovery of the puncture site, so there is room for improvement. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the utility model provides a disposable micro-pressure micro-airbag hemostatic patch to solve the technical problems that the existing hemostatic patches are usually "straight-line" shaped, cannot compress and stop bleeding well, and easily cause concentrated pressure at the wound location, which is not conducive to the recovery of the puncture site.

[0006] A disposable micro-pressure micro-airbag hemostatic patch includes two groups of dressings and a blood seepage layer. The two groups of dressings are cross-symmetrically arranged and arranged in an "X" shape. The overlapping part of the dressing is the pressure area, and the blood seepage layer is arranged opposite to the pressure area. Both ends of each group of the dressings are provided with an adhesive layer, and each group of the adhesive layers is covered with release paper.

[0007] Preferably, a pressure balloon is provided on the pressure area, and the pressure balloon is embedded between the overlapping positions of the two groups of patches.

[0008] Preferably, the blood seepage absorbing material of the blood seepage layer is a mixed material of gelatin sponge and gel.

[0009] Preferably, the adhesive layer material is silicone.

[0010] Preferably, the adhesive layer is provided in a local area of ​​the patch.

[0011] Preferably, the dressing is made of elastic, breathable non-woven gauze.

[0012] Preferably, the pressure balloon and the patch are an integrated structure.

[0013] Preferably, the pressure balloon is a hemispherical structure.

[0014] Preferably, the release paper is made of PET.

[0015] Preferably, the area of ​​the release paper is larger than the area of ​​the adhesive layer.

[0016] The beneficial effects of the utility model are:

[0017] 1. Through the X-shaped setting, the pressure can be dispersed to a larger area around the wound, reducing local pressure and avoiding poor blood circulation and tissue ischemia caused by excessive local pressure; the X-shaped setting can make the two groups of dressings arranged crosswise and symmetrically, so as to achieve uniform pressure on the wound. This helps to promote blood circulation around the wound, accelerate metabolism, and facilitate the healing and recovery of the wound; the X-shaped setting can stimulate the microcirculation around the wound, help blood supply and oxygen delivery, and accelerate the healing and recovery of the wound;

[0018] 2. By using the overlapping part of the patch as the pressure area, when the hemostatic patch is covered on the wound, the pressure area can provide micro-pressure to help stop bleeding and promote blood coagulation; the blood seepage layer is set opposite to the pressure area, which can quickly absorb the blood seeping from the wound, keep the wound dry, and promote wound healing; the setting of the adhesive layer can make the hemostatic patch firmly adhere to the skin, not easy to fall off, and fix the position of the hemostatic patch; the release paper can keep the hemostatic patch clean to avoid contamination and cross infection;

[0019] 3. By using a mixed material of gelatin sponge and gel as the blood absorbing material of the bleeding layer, the mixed material of gelatin sponge and gel can quickly absorb the blood seeping from the wound, reduce the residence time of blood on the wound surface, help stop bleeding and keep the wound clean; this material can maintain a moist environment around the wound, which is conducive to wound healing and reduces pain and discomfort; the gel mixed material can promote blood coagulation and help stop bleeding; the mixed material of gelatin sponge and gel usually has good anti-adhesion properties and reduces damage to the wound.

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] After the patient has finished intravenous infusion or arterial / venous blood sampling treatment, in order to stop bleeding at the puncture site as soon as possible, the nurse will usually ask the patient to press the puncture site with a cotton swab after the needle is removed to achieve the purpose of hemostasis. However, patients with poor coagulation function need to press for a long time. For patients with large bleeding, blood may penetrate the cotton swab. Excessive pressing can also cause local tissue damage or congestion. Especially for cancer patients, frequent arterial / venous punctures are required for treatment or examination during the recovery process. In order to better protect the patient's blood vessels, reduce the hematoma rate after pressing, relieve pain, and more conveniently compress and stop bleeding, a hemostatic patch is needed to assist in pressing.

[0031] Common hemostatic patches are shown in the invention patent with application number 201710898410.6: Hemostatic cotton patch. The hemostatic cotton patch includes fixing glue and hemostatic cotton. A hemostatic sheet is provided on the hemostatic cotton. The hemostatic sheet is in a low-temperature state and is flat and thin when not in use. When the hemostatic sheet covers the puncture site, the heat of the skin and blood causes the hemostatic sheet to expand rapidly. At this time, the pressure of the hemostatic sheet on the puncture site gradually increases, forming a certain pressure on the puncture site to prevent bleeding from the wound.

[0032] The hemostatic patch mentioned above is a single hemostatic material, and is mainly used to apply local compression to the puncture site to stop bleeding. The overall shape of the hemostatic patch is mostly "single-line". The "single-line" hemostatic patch only has a force in one direction on the patient's puncture site, and medical staff and patients cannot promptly determine whether the pressure is in a suitable state. For patients with poor coagulation function or patients with a large amount of bleeding, the local pressure of the hemostatic patch and the pressure in one direction of the hemostatic patch cannot effectively stop bleeding. At the same time, the hemostatic patch only has a force in one direction on the patient's puncture site, which can easily cause concentrated pressure at the wound site, and easily form bruises, redness and swelling at the puncture site, which is not conducive to the recovery of the puncture site.

[0033] In order to solve the above-mentioned technical problems, the utility model provides a disposable micro-pressure micro-airbag hemostatic patch to solve the technical problems that the existing hemostatic patches are usually "straight-line" shaped, cannot compress and stop bleeding well, and easily cause concentrated pressure at the wound location, which is not conducive to the recovery of the puncture site.

[0034] Please refer to 1- Figure 4The present application proposes a disposable micro-pressure micro-airbag hemostatic patch, which includes two groups of dressings 1 and a blood seepage layer 2. The two groups of dressings 1 are arranged crosswise and symmetrically and are arranged in an "X" shape. The overlapping part of the dressing 1 is the pressure application area, and the blood seepage layer 2 is arranged opposite to the pressure application area. Both ends of each group of dressings 1 are provided with an adhesive layer 3, and each group of adhesive layers 3 is covered with a release paper 4. The X-type setting can disperse the pressure to a larger area around the wound, reduce local pressure, and avoid poor blood circulation and tissue ischemia caused by excessive local pressure; the X-type setting can make the two groups of dressings 1 arranged crosswise and symmetrically, so as to achieve uniform pressure on the wound. This helps to promote blood circulation around the wound, accelerate metabolism, and is conducive to the healing and recovery of the wound; the X-type setting can stimulate the microcirculation around the wound, help blood supply and oxygen delivery, and accelerate the healing and recovery of the wound.

[0035] The overlapping part of the dressing 1 serves as a pressure area. When the hemostatic patch covers the wound, the pressure area can provide micro-pressure to help stop bleeding and promote coagulation; the blood seepage layer 2 is arranged opposite to the pressure area, which can quickly absorb the blood seeping from the wound, keep the wound dry, and promote wound healing; the setting of the adhesive layer 3 can make the hemostatic patch firmly adhere to the skin, not easy to fall off, and fix the position of the hemostatic patch; the release paper 4 can keep the hemostatic patch clean and avoid contamination and cross infection.

[0036] Traditional hemostatic patches usually squeeze the wound after the blood seepage layer 2 absorbs water and expands, but due to the limited water absorption and expansion capacity of the blood seepage layer 2, the applied pressure is small, and it is difficult to achieve effective squeezing of the wound, resulting in poor hemostatic effect; due to the small pressure, when facing large-area bleeding or large wounds, traditional hemostatic patches are often difficult to effectively control the amount of bleeding, resulting in poor hemostatic effect. Based on this, in one embodiment, a pressure balloon 5 is provided on the pressure area, and the pressure balloon 5 is embedded between the overlapping positions of the two groups of patches 1. When the blood seepage layer 2 absorbs water and expands, the pressure balloon 5 will apply appropriate pressure to the wound, which helps to compress the blood vessels and promote coagulation, thereby playing a hemostatic role; by squeezing the wound with the pressure balloon 5, the amount of bleeding of the wound can be effectively controlled, blood loss can be reduced, and it is beneficial to wound healing; the squeezing effect of the pressure balloon 5 can promote platelet aggregation and activation of coagulation factors on the surface of the wound, which helps to accelerate the coagulation process and promote hemostasis.

[0037] The bleeding absorption material of the bleeding layer 2 of the traditional hemostatic patch is usually made of natural fiber materials such as cotton yarn or gauze; the absorption capacity of natural fiber materials is limited, and they cannot quickly and effectively absorb a large amount of bleeding, which may cause the blood to stay on the wound surface for too long, affecting the hemostatic effect; the natural fiber materials have good air permeability, which easily makes the environment around the wound too dry, which is not conducive to wound healing; the natural fiber materials are easy to adhere to the wound surface, and may cause secondary damage to the wound when torn off. Based on this, in one embodiment, the bleeding absorption material of the bleeding layer 2 is a mixed material of gelatin sponge and gel. The mixed material of gelatin sponge and gel can quickly absorb the blood exuded from the wound, reduce the residence time of blood on the wound surface, help stop bleeding and keep the wound clean; this material can maintain a moist environment around the wound, which is conducive to wound healing and reduces pain and discomfort; it can achieve shaping and extrusion, better fit the skin of the puncture site, absorb the bleeding and convert it into new micro-pressure after it becomes larger, and help stop bleeding; the mixed material of gelatin sponge and gel usually has good anti-adhesion properties and reduces damage to the wound. At the same time, the gel material is comfortable and breathable. It can quickly absorb body temperature, lower body temperature through evaporation, maintain low temperature for a long time, and reduce local tissue edema.

[0038] The adhesive layer 3 of a traditional hemostatic patch is usually made of acrylic glue. Some people may have allergic reactions to the ingredients in acrylic glue, resulting in adverse reactions such as itching and redness of the skin; acrylic glue has poor air permeability, which may cause the skin around the wound to become moist, which is not conducive to wound healing; acrylic glue may have poor tearing properties, which is not convenient to use. Based on this, in one embodiment, the adhesive layer 3 is made of silicone. The silicone adhesive layer 3 can effectively adhere to the skin surface, provide a lasting fixing effect, and is not easy to fall off; the silicone adhesive layer 3 has good air permeability, allowing air and water vapor to pass through, which is beneficial to wound healing and skin breathing; the silicone adhesive layer 3 is soft and comfortable, has little irritation to the skin, and helps to improve the patient's comfort; the silicone adhesive layer 3 is usually less allergic to the skin and is suitable for more people; the silicone adhesive layer 3 has good tearing properties, which can easily replace the hemostatic patch and reduce damage to the skin.

[0039] The traditional adhesive layer 3 is completely covered on the patch 1, which may cause the patch 1 and the skin to be torn off together when being torn off, increasing the difficulty of tearing off; when being torn off, the adhesive substance may remain on the skin, requiring strong pulling, which may easily cause secondary damage to the skin, and even cause adverse reactions such as abrasions, redness and swelling; especially for patients with sensitive skin, the tearing process may cause discomfort and pain. Based on this, in one embodiment, the adhesive layer 3 is arranged in a local area of ​​the patch 1. The adhesive layer 3 is arranged in a local area of ​​the patch 1, and the adhesive layer 3 has good tearing properties, and the hemostatic patch can be easily attached and torn off, which is more convenient to use; it reduces the secondary damage to the wound when the hemostatic patch is torn off, and avoids adverse reactions such as pain and bleeding; it avoids the adhesion of the hemostatic patch to the wound surface, reduces the irritation and pain to the skin when the hemostatic patch is torn off, and improves the comfort of the patient.

[0040] Traditional hemostatic patches usually use medical tape with a sticky glue layer as the material of the patch 1. This medical tape usually uses polyethylene film or paper material as the base material, and is coated with a medical glue layer on the back, which is used to adhere to the wound surface to stop bleeding and protect the wound. The traditional medical tape material has poor air permeability, which may cause the skin around the wound to become moist, which is not conducive to wound healing. Based on this, in one embodiment, the patch 1 uses elastic breathable non-woven gauze. The non-woven gauze has good air permeability, allowing air and water vapor to pass through, which is conducive to the excretion and healing of the wound and reduces the possibility of bacterial growth; the breathable non-woven gauze is soft and comfortable, will not cause discomfort to the patient, and helps to improve the patient's comfort; the elastic non-woven gauze can fit the curve of the wound site, provide better fit, and is conducive to the fixation and wrapping of the hemostatic patch on the wound, reducing the possibility of displacement; the breathable non-woven gauze usually has a certain water absorption, which can absorb the blood and secretions exuded from the wound, keep the wound dry, and is conducive to wound healing.

[0041] In order to make the pressure balloon 5 fit more closely to the wound surface, in one embodiment, the pressure balloon 5 and the dressing 1 are an integrated structure. Since the pressure balloon 5 and the dressing 1 are an integrated structure, the pressure balloon 5 can fit more closely to the wound surface, thereby providing a greater pressure force, which helps to squeeze the wound more effectively and promote hemostasis; the integrated structure can ensure that the pressure balloon 5 fits the wound fully, thereby better controlling the amount of bleeding, reducing blood loss, and facilitating wound healing; the integrated structure can better adapt to wounds of different shapes and sizes, ensuring that the pressure balloon 5 can effectively apply pressure, which is conducive to achieving a wider range of applications.

[0042] In order to more effectively promote the hemostasis function, in one embodiment, the pressure balloon 5 is a hemispherical structure, and the plane layer of the hemispherical structure is combined with the wound patch to squeeze the wound. The design of the hemispherical structure can ensure that the pressure is evenly distributed on the wound surface, avoiding the situation where the local pressure is too large or too small, which helps to promote hemostasis more effectively; the design of the hemispherical structure can better adapt to wounds of different shapes and sizes, ensuring that the pressure balloon 5 can fully fit on the wound surface, thereby providing a more comprehensive hemostasis effect. Compared with structures of other shapes, the hemispherical structure can reduce the pressure on the tissues around the wound, reduce the damage to the surrounding normal tissues, and is conducive to wound healing.

[0043] The release paper 4 of the adhesive layer 3 on the traditional hemostatic patch is usually made of silicone paper or glass paper. The release paper 4 of these materials can protect the adhesive layer 3 of the hemostatic patch to a certain extent, but there are also some defects. Silicone paper is easily affected by moisture and absorbs dust, which reduces the viscosity; although glass paper has good moisture resistance, it is easy to generate static electricity when torn off, resulting in adhesion to the adhesive layer 3, affecting the use effect of the hemostatic patch. Based on this, in one embodiment, the release paper 4 is made of PET material. The release paper 4 of PET material can effectively protect the adhesive layer 3 on the hemostatic patch and prevent the adhesive layer 3 from being contaminated or damaged during transportation and storage. PET material has good heat resistance and chemical resistance, can maintain the quality and viscosity of the adhesive layer 3, and ensure that the hemostatic patch can effectively adhere to the wound and play a hemostatic role when in use. At the same time, the release paper 4 of PET material also has certain air permeability and moisture resistance, which can effectively prevent the adhesive layer 3 from being damp or polluted by air, and extend the service life of the hemostatic patch.

[0044] When the area of ​​the release paper 4 is equal to the area of ​​the adhesive layer 3, the user may find it difficult to accurately find the edge of the release paper 4 during use, which makes it inconvenient to tear it off and increases the complexity of use; the area of ​​the release paper 4 being equal to the area of ​​the adhesive layer 3 means that the user needs to directly contact the adhesive layer 3 when tearing off the release paper 4, which increases the risk of the adhesive layer 3 being contaminated by the outside, especially when the external environment is not very clean; direct contact with the adhesive layer 3 may cause a loss of viscosity, because the grease or dust on the fingers may adhere to the adhesive layer 3, reducing its viscosity. Based on this, in one embodiment, the area of ​​the release paper 4 is larger than the area of ​​the adhesive layer 3. The large area of ​​release paper 4 can provide a larger gripping area, making it easier for users to tear off the release paper 4 during use, avoiding direct contact of fingers with the adhesive layer 3, and reducing the risk of contamination and cross-infection; the large area of ​​release paper 4 can better cover and protect the adhesive layer 3, preventing the adhesive layer 3 from being contaminated or damaged during transportation and storage, and maintaining its viscosity and quality; the large area of ​​release paper 4 is easier to grasp when tearing, which can reduce the risk of tearing the adhesive layer 3, and ensure that the hemostatic patch can effectively adhere to the wound and play a hemostatic role when in use.

[0045] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
