Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a medical hemostatic patch device. Background Art

[0002] In the daily work of hospitals, hemostatic patches or hemostatic patches with dressings are needed after surgical dressing of skin lesions, dressing of wounds in dermatology, and arteriovenous puncture. Taking arteriovenous puncture as an example, the traditional hemostasis method is that after puncture, the nurse takes the patch with one hand and presses the puncture site, and then the nurse, the patient or the patient's family member continues to press the puncture site. It is very easy to cause adverse conditions such as bruising, bleeding, and subcutaneous hematoma due to insufficient pressing force, improper pressing position, and insufficient pressing time.

[0003] To solve the above problems, the prior art adopts a pressurized hemostatic patch. The common solutions of the pressurized hemostatic patch are as follows:

[0004] 1. An airbag package filled with vacuum sponge is arranged in the structure of the pressurized hemostatic patch. After puncture, the airbag package of the pressurized hemostatic patch is aligned with the puncture site and pasted, and then the tear opening on the side of the airbag package is torn open, so that the vacuum sponge in the airbag package quickly inhales air and expands, thereby pressing the puncture site. This pressurized hemostatic patch can solve the problems of insufficient manual pressing force, improper pressing position, and insufficient pressing time. However, it takes a certain amount of time for the vacuum sponge in the airbag package to inhale air and expand to the pressure that can stop bleeding. During this period, the pressure at the puncture site is insufficient, which may cause bleeding of the puncture point skin and / or blood vessels.

[0005] 2. A main airbag and an auxiliary airbag are arranged in the structure of the pressurized hemostatic patch. After puncture, the main airbag of the pressurized hemostatic patch is aligned with the puncture site and pasted, and then the auxiliary airbag is pressed so that the gas in the auxiliary airbag flows into the main airbag, making the main airbag a pressurized airbag. This pressurized hemostatic patch can solve the problems of insufficient manual pressing force, improper pressing position, and insufficient pressing time. However, it takes a certain amount of time for the gas to inflate from the auxiliary airbag to the main airbag and for the main airbag to expand to the pressure that can stop bleeding. During this period, the pressure at the puncture site is insufficient, which may cause bleeding of the puncture point skin and / or blood vessels.

[0006] In addition, before puncture, the nurse generally pastes the hemostatic patch at a convenient position for access, such as the sleeve of the nurse's uniform, the desktop, etc., which is likely to contaminate the hemostatic patch. After trauma or surgery, the nurse needs to open the dressing patch, and during this process, due to reasons such as improper operation, the dressing patch is easily contaminated. Summary of the Utility Model

[0011] Preferably, the sterile hemostatic layer is a sterile gauze layer, or the sterile hemostatic layer is a sterile gauze layer with a dressing.

[0012] Preferably, in the initial state, the inner walls at the air outlet of the auxiliary airbag are temporarily adhered together to prevent the gas pre - filled in the auxiliary airbag from flowing into the pressure - applying airbag; in the pressurized state, the gas pressure in the auxiliary airbag breaks through the adhesive force of the inner walls at the air outlet of the communicating airbag, realizing the flow of the gas pre - filled in the auxiliary airbag into the pressure - applying airbag.

[0016] Preferably, a one-way valve that only allows gas to flow unidirectionally from the auxiliary airbag towards the pressurizing airbag is provided on the inner wall of the connecting airbag close to the pressurizing airbag.

[0017] The pressurizing airbag and the auxiliary airbag of the medical hemostatic patch device of the present invention are stacked together. In this way, when pressing the auxiliary airbag to inflate the pressurizing airbag, the pressure applied to the auxiliary airbag is applied to the bleeding site through the pressurizing airbag, which can ensure the timeliness of pressurized hemostasis and avoid the occurrence of bruising and hematoma caused by untimely pressurization, such as skin and / or vascular bleeding; in addition, the first and second adhesive patches of the medical hemostatic patch device are connected together, and the second adhesive patch can be folded relative to the first adhesive patch.

[0023] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The present invention discloses a medical hemostatic patch device, which includes: a first adhesive patch, a second adhesive patch, a sterile hemostatic layer, a pressure airbag, and an auxiliary airbag. Among them:

[0025] I. The first adhesive patch is used to semi - surround or surround the operation area, and the side thereof in contact with the skin is the first adhesive layer.

[0026] See Figure 1 and Figure 2 , the first adhesive patch 1 can be a U - shaped structure, and this U - shaped structure defines the operation area in a semi - surrounding manner. The operation area is a sterile area (or a disinfected area) that meets the requirements of treatment or puncture operations. Specifically, it can be an area containing skin lesions, an area containing wounds, an area containing arteriovenous puncture points, etc.

[0027] In addition, the first adhesive patch can also adopt other structures that can define the operation area, such as a circular structure that can surround the operation area, etc.

[0028] The side of the first adhesive patch 1 in contact with the skin is the first adhesive layer (not labeled). Correspondingly, a first protective film is arranged outside the first adhesive layer. During use, removing the first protective film can expose the first adhesive layer, and then the first adhesive patch 1 can be attached to the skin.

[0029] During design, the structure, size of the first adhesive patch 1, and the shape and area of the operation area defined by it can be determined according to the actual application situation.

[0030] II. The second adhesive patch is connected to the first adhesive patch and can be folded relative to the first adhesive patch to expose or cover the operation area. The side thereof in contact with the skin is the second adhesive layer.

[0031] See Figure 1 and Figure 2 , the second adhesive patch 2 and the first adhesive patch 1 are of an integral structure. Among them, the inner edges of the two arms of the U - shaped structure of the second adhesive patch 2 are not connected to the first adhesive patch 1, and the inner edge of the bottom of the U - shaped structure of the second adhesive patch 2 is connected to the first adhesive patch 1. After the first adhesive patch 1 is attached to the skin, the second adhesive patch 2 can be folded relative to the first adhesive patch 1 with the connection point of the inner edge of the bottom of the U - shaped structure of the second adhesive patch 2 and the first adhesive patch 1 as the axis.Figure 2 The medical hemostatic patch device is a schematic diagram of a medical hemostatic patch after folding the second adhesive patch 2 in Figure 1 by 180 degrees. In fact, the folding angle may be any angle between 0 and 180 degrees. During application, as long as this angle does not affect the operation of medical staff in the operation area. For example, the angle is any angle between 90 and 150 degrees. Further, the present utility model can stabilize the folding angle at a specific angle, such as 90 degrees or slightly greater than 90 degrees. Taking 100 degrees as an example, to achieve this specific angle, a connecting member with a maximum opening and closing angle of 100 degrees can be provided at the middle position of the folding line between the second adhesive patch 2 and the first adhesive patch 1 shown in Figure 1 (for example, a hinge is provided, and the two blades of the hinge are respectively fixedly connected to the first and second adhesive patches). In this way, on the one hand, it helps the visual operation of medical staff, and on the other hand, the second adhesive patch 2 will not touch the surfaces of bacteria-containing objects such as the skin and clothes outside the operation area during the folding process or in the folded state, effectively avoiding the contamination of the second adhesive patch 2. Thus, after the second adhesive patch 2 covers the operation area, it will not contaminate the operation area, especially the skin lesions / wounds / puncture points in the operation area.

[0032] In addition, when the first adhesive patch 1 is the U-shaped structure shown in Figure 2 , the connection position between the second adhesive patch 2 and the first adhesive patch 1 can also be the inner edge of the two arms of the U-shaped structure, the outer edge of the two arms of the U-shaped structure, and the outer edge of the bottom of the U-shaped structure; when the first adhesive patch 1 is a circular structure, the connection position between the second adhesive patch 2 and the first adhesive patch 1 can be the inner edge of the circular structure or the outer edge of the circular structure. In short, the connection position between the first adhesive patch and the second adhesive patch can be any position that meets the requirement that "the second adhesive patch 2 can be folded relative to the first adhesive patch 1 to cover or expose the operation area".

[0033] The side of the second adhesive patch 2 that adheres to the skin is a second adhesive layer (not marked). Correspondingly, a second protective film is provided outside the second adhesive layer. During use, the second protective film is removed to expose the second adhesive layer, and the second adhesive patch 2 is adhered to the skin.

[0034] During design, the shape and size of the second adhesive patch 2 can be determined according to the structure and size of the first adhesive patch, the shape and area of the operation area defined by it, and the connection position between the first and second adhesive patches.

[0035] In the present utility model, the first adhesive patch and the second adhesive patch are connected together, and the second adhesive patch can be folded relative to the first adhesive patch to a suitable position, which can not only ensure that the operation area is exposed for visual operation by medical staff, but also ensure that the second adhesive patch is convenient to take and will not be contaminated, thus ensuring aseptic operation. ​​​​​​

[0036] III. Sterile Hemostatic Layer

[0037] See Figure 2 , Figure 3 , Figure 4 The sterile hemostatic layer 3 is disposed on the middle surface of the second adhesive layer on one side of the second adhesive patch 2, and its edge is fixedly connected to the second adhesive layer.

[0038] This sterile hemostatic layer is in direct contact with the skin lesion, wound surface, and arteriovenous puncture site. According to the need for applying medicine, the medical hemostatic patch device can be divided into the following two types:

[0039] 1. The sterile hemostatic layer used in the medical hemostatic patch device is a sterile gauze layer, which is suitable for patients with only hemostatic needs, such as ordinary patients undergoing venous blood collection.

[0040] 2. The sterile hemostatic layer used in the medical hemostatic patch device is a sterile gauze layer with a dressing, which is suitable for patients who need both medicine application and hemostasis, such as patients with skin lesions or wounds.

[0041] IV. Pressurizing Airbag and Auxiliary Airbag

[0042] See Figure 1 and Figure 3 The pressurizing airbag 4 is disposed between the second adhesive layer and the sterile hemostatic layer, and no gas is pre-filled inside. The auxiliary airbag 5 is disposed on the other surface of the second adhesive patch opposite to the second adhesive layer, and gas is pre-filled inside. Among them, the line connecting the centers of the pressurizing airbag 4 and the auxiliary airbag 5 is perpendicular to the second adhesive patch 2.

[0043] The pressurizing airbag 4 can adopt a semi-elliptical airbag. The material hardness / elasticity of the side of the pressurizing airbag 4 close to the skin (i.e., the side close to the auxiliary airbag 5, which is a plane) and the side far from the skin (i.e., the side close to the auxiliary airbag 5, which is a semi-ellipsoidal surface) can be the same. For example, both sides adopt a soft surface material in the prior art that can undergo elastic deformation during the inflation process; the material hardness / elasticity of the side of the pressurizing airbag 4 close to the skin and the side far from the skin can also be different. For example, the side of the pressurizing airbag 4 far from the skin adopts a hard surface material in the prior art that does not undergo elastic deformation, and the side of the pressurizing airbag 4 close to the skin adopts a soft surface material in the prior art that can undergo elastic deformation during the inflation process. Compared with the former, the pressurizing effect is better.

[0044] The auxiliary airbag 5 can adopt a cylindrical airbag or a spherical airbag. The auxiliary airbag 5 can be made of an existing elastic material or an existing material that can contract but is not prone to elastic deformation. Compared with the former, after being pressed, it is easier to squeeze the internal gas into the pressurizing airbag 4.

[0045] When using the medical hemostatic patch device, with the position to be operated such as skin lesions, wounds, puncture points, etc. as the center, the first adhesive patch 1 is attached to the skin, and the second adhesive patch 2 is folded relative to the first adhesive patch 1, so that the operation area surrounded or semi-surrounded by the first adhesive patch 1 is exposed to the sight of medical staff, facilitating visual operations such as disinfection, treatment, and puncture by medical staff within the operation area. After the medical staff completes the operation on the operation area, the second adhesive patch 2 is covered on the operation area defined by the first adhesive patch 1, and at the same time, the auxiliary airbag 5 is pressed. Since the auxiliary airbag 5 is on the other side surface of the second adhesive patch opposite to the second adhesive layer, that is, the visible side, the auxiliary airbag 5 can be observed to ensure that the gas pre-filled in the auxiliary airbag 5 basically all flows into the pressurizing airbag 4, thereby realizing the pressurizing hemostasis function of the pressurizing airbag 4.

[0046] In the present utility model, the pressurizing airbag 4 and the auxiliary airbag 5 of the medical hemostatic patch device are stacked together. In this way, when pressing the auxiliary airbag 5 with one hand to inflate the pressurizing airbag 4, the pressure applied to the auxiliary airbag 5 is applied to the part that needs hemostasis through the pressurizing airbag 4, that is, pressing and airbag-conducted pressurization are completed simultaneously with one hand. This is not only simple in operation but also can ensure the timeliness of pressurizing hemostasis and avoid skin and / or blood vessel bleeding caused by untimely pressurization.

[0047] Furthermore, the inner wall at the air outlet of the auxiliary airbag 5 is coated with an adhesive that can temporarily stick the inner walls at the outlet together. In the initial state when the medical hemostatic patch device is not in use, the inner walls at the air outlet of the auxiliary airbag 5 are temporarily adhered together to prevent the gas pre-filled in the auxiliary airbag 5 from flowing to the pressurizing airbag 4 that is not pre-filled with gas, causing the device to fail; when the medical hemostatic patch device is in use and in a pressurized state, the auxiliary airbag 5 is pressed, and the gas pressure in the auxiliary airbag 5 breaks through the adhesive force of the adhesive coated on the part where the inner walls at the outlet are adhered together, separating the temporarily adhered inner walls at the outlet, thereby opening the gas flow channel between the auxiliary airbag 5 and the pressurizing airbag 4, realizing the gas pre-filled in the auxiliary airbag 5 flowing to the pressurizing airbag 4. In addition, except for the inner wall at the air outlet of the auxiliary airbag 5, there is an adhesive layer that can permanently stick the inner walls together. In the initial state when the medical hemostatic patch device is not in use, the auxiliary airbag 5 is pre-filled with gas, so the inner walls of the auxiliary airbag 5 are separated. When the medical hemostatic patch device is in use and the auxiliary airbag 5 is pressed, the auxiliary airbag 5 continuously shrinks as the gas flows out, and finally the inside of the auxiliary airbag 5 is permanently adhered together, effectively preventing the gas in the pressurizing airbag 4 from flowing back to the auxiliary airbag 5, ensuring the pressure of the pressurizing airbag 5 on the hemostatic part after the pressing ends and ensuring the hemostasis effect.

[0048] See Figure 3 and Figure 4, the device may further include a connecting airbag 6, which can also be made of an elastic material and passes through the second adhesive patch to connect the pressurizing airbag 4 and the auxiliary airbag 6.

[0049] As an alternative or supplement to the solution of "temporarily pasting the inner wall of the air outlet of the auxiliary airbag 5", the inner wall of the connecting airbag 6 close to the auxiliary airbag 6 is coated with an adhesive that can temporarily paste the inner walls together. In the initial state when the medical hemostatic patch device is not in use, the inner walls of the connecting airbag 6 close to the auxiliary airbag 5 are temporarily adhered together, thus disconnecting the gas passage between the auxiliary airbag 5 and the pressurizing airbag 4, preventing the pre-charged gas in the auxiliary airbag 5 from flowing to the pressurizing airbag 4 that is not pre-charged with gas and causing the device to fail; when the medical hemostatic patch device is in use and in a pressurized state, pressing the auxiliary airbag 5 causes the gas pressure in the auxiliary airbag 5 to break through the adhesive force of the adhesive coated on the part where the inner walls of the connecting airbag 6 close to the auxiliary airbag 5 are adhered together, separating the temporarily adhered inner walls, thereby connecting the gas passage between the auxiliary airbag 5 and the pressurizing airbag 4 and enabling the pre-charged gas in the auxiliary airbag 5 to flow to the pressurizing airbag 4.

[0050] As an alternative or supplement to the solution of "a glue layer that can permanently paste the inner walls together is provided on the inner walls of the auxiliary airbag 5 other than the inner wall at the air outlet", a one-way valve (not marked) that can only allow gas to flow unidirectionally from the auxiliary airbag 5 towards the pressurizing airbag 4 can be provided on the inner wall of the connecting airbag 6 close to the pressurizing airbag 4, preventing the gas that has flowed into the pressurizing airbag 4 from flowing back to the auxiliary airbag 5 again, ensuring the pressure of the pressurizing airbag 5 on the hemostatic part after the pressing is completed, and ensuring the hemostatic effect.

[0051] It should be added that the second adhesive patch 2, the pressurizing airbag 4, and the auxiliary airbag 5 can be opaque or transparent. Compared with the former, the latter helps to observe whether there is blood oozing from the sterile hemostatic layer 3, so as to quickly discover the bleeding condition of the skin lesion / wound / puncture position in the operation area and facilitate the timely handling by medical staff.

[0052] In addition, during arteriovenous puncture for blood collection, the operation of fixing the syringe plug is mainly to ensure the stability and safety of the needle during blood collection, so as to successfully complete the blood collection task. However, if the operation of fixing the syringe plug is improper, it may also bring risks such as blood vessel injury, nerve injury, and infection. Therefore, considering the arteriovenous puncture scenario, the medical hemostatic patch device of the present utility model may further include: a fixing band (not marked) for fixing the syringe plug, one end of which is fixedly connected to a first position on the other surface of the first adhesive patch opposite to the first adhesive layer, and the other end of which is detachably connected to a second position on the other surface of the first adhesive patch opposite to the first adhesive layer. The first and second positions can be two different positions on the first adhesive patch suitable for fixing the syringe plug. Additionally, for example, the detachable connection structure can be realized through a pair of connecting members, such as mother and son magic tapes.

[0053] The embodiments of the present utility model described above with reference to the accompanying drawings do not thereby limit the scope of the rights of the present utility model. Any modifications, equivalent replacements, and improvements made by those skilled in the art without departing from the scope and essence of the present utility model shall fall within the scope of the rights of the present utility model.
