Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical technology, and in particular to a method for forming a dressing patch for pressure hemostasis of fingers or toes and the dressing patch. Background Art
[0002] The number of patients with malignant melanoma, nail matrix tumors, nail pigmented nevi, and ingrown nails on the fingers and toes is increasing year by year, and finger and toe trauma is relatively common in daily life. The fingers and toes have a rich blood supply, many capillaries, a large number of nerves, and are sensitive to pain. Especially after surgery, alginate dressings are often used to cover the wound and then fix it with a bandage to stop bleeding, reduce local pain, and promote wound healing. Bandaging routinely requires multiple layers of gauze to cover and apply pressure. Since the strength of manual pressure to stop bleeding varies from person to person, it often leads to an increase in bleeding and infection. When using a bandage to fix it, each medical staff member applies different pressure and pressure techniques, which often leads to an increase in postoperative bleeding and infection. In addition, during dressing changes, the dressing is often difficult to fall off the wound easily. When removing the dressing, it is easy to cause traction on the finger (toe) tip, causing wound pain and even causing capillary rupture and bleeding. This prolongs the dressing change time, increases the workload of nurses, and also increases the risk of wound infection.
[0003] In addition, although there are band-aids available in the prior art, such as the airbag band-aid with application number 201620535753.7, it requires a valve and compressed air, has a complex structure, high cost, and cumbersome operation, and is especially not suitable for delicate parts such as fingers or toes.

[0037] like Figure 1-Figure 3 The figures shown are schematic diagrams of the structures of the dressing patch for fingers and toes of the present invention when different structures are adopted. As can be seen from the figure, the dressing patch for fingers and toes of the present invention includes: a main air bag 2 pre-filled with gas inside and with a dressing layer on the outside; an auxiliary air bag 4 located on one side of the main air bag, the interior of which is pre-filled with gas that can be squeezed into the inner cavity of the main air bag and the inner wall of which can be fixedly connected together after the gas is squeezed out; a fixing belt arranged on the outside of the main air bag and the auxiliary air bag, the inner wall of which is fixedly connected to the outer surface of both, and a connecting piece is provided at each end. When it is necessary to apply pressure to stop bleeding on the finger or toe, the fixing belt and its inner wall air bag are fixed to the part of the finger or toe to be stopped bleeding by a pair of connecting pieces of the fixing belt, and the pre-filled gas inside the auxiliary air bag is squeezed to enter the main air bag and mix with the pre-filled gas in the main air bag. Under the action of the fixing belt, pressurized gas is formed to apply pressure to stop bleeding on the part to be stopped bleeding.
[0038] Specifically, the dressing patch of the present invention includes: a fixing belt with connectors provided at both ends, and a main airbag and an auxiliary airbag provided on the inner wall of the fixing belt in the vertical direction along the width direction of the fixing belt.
[0039] The fixing belt is a latex belt made of latex, including: a main airbag fixing portion 12 for fixing the main airbag thereon; a main airbag fixing portion 12 located on one side of the main airbag fixing portion (such as Figure 1 、 Figure 5a-Figure 8b The foldable portion 11 is located on the other side of the main airbag fixing portion (as shown in FIG. Figure 1 The auxiliary airbag fixing portion 13 is shown on the lower side).
[0040] The main airbag fixing part and the auxiliary airbag fixing part are respectively long strips, and are arranged in parallel, with a part in the middle fixedly connected together (the fixed connection position corresponds to the position of the main airbag), and the two sides are separated. The foldable part is rectangular, located in the middle position of the upper side of the main airbag fixing part, and the lower edge is fixedly connected to the upper edge of the main airbag fixing part. The length of the foldable part is greater than the length of the main airbag fixing part or the auxiliary airbag fixing part (length refers to Figure 1The dimension in the vertical direction of the middle part, that is, when fixed on the finger, is consistent with the length extension direction of the finger), the width of the foldable part is smaller than the width of the main airbag fixing part or the auxiliary airbag fixing part (the width refers to the width of the main airbag fixing part or the auxiliary airbag fixing part). Figure 1 The size of the middle along the left and right direction, that is, when fixed on the finger 8, can be seen Figure 5a , which is consistent with the direction perpendicular to the extension direction of the finger length).
[0041] During design, the dimensions of each part of the fixing belt can be determined according to actual conditions, so that after the main airbag is aligned with the part of the finger or toe to be hemostatic, the length of the foldable part can at least be able to go around from the front end of the nail from below the part to be hemostatic, and fold over to above the part to be hemostatic, that is, it can at least cover the area opposite to the part of the finger / toe to be hemostatic, and can be covered when the main airbag fixing part wraps around the finger / toe, so as to provide better wrapping integrity and pressure retention capability; and the width of the main airbag fixing part and the auxiliary airbag fixing part should be able to wrap around the part of the finger or toe to be hemostatic for more than one circle; the length of the connecting part of the main airbag fixing part and the auxiliary airbag fixing part can be almost the same as the width of the finger, and the position of the connecting part corresponds to the position of the main airbag and the auxiliary airbag. In addition, the widths of the main airbag fixing part and the auxiliary airbag fixing part located on the left and right sides of the connecting part can be the same or different.
[0042] The two ends of the main airbag fixing portion and the two ends of the auxiliary airbag fixing portion of the fixing strap are respectively connected together by a pair of connectors. That is, a first pair of connectors is provided at each end of the main airbag fixing portion, and a second pair of connectors is provided at each end of the auxiliary airbag fixing portion. The two connectors of each pair of connectors are fixed to the two ends of the corresponding fixing portion by gluing, sewing, or other methods known in the art. During manufacturing, one connector is located on the inner wall (also known as the front) of the corresponding fixing portion, and the other connector is located on the outer wall (also known as the back) of the fixing portion. The pair of connectors can respectively adopt a male Velcro and a female Velcro, or can adopt other structures known in the art that can be detachably connected together.
[0043] Among them, the auxiliary airbag and the main airbag can adopt cylindrical airbags, elliptical airbags, ellipsoidal airbags, or spherical airbags, etc., which are respectively arranged at the center position of the corresponding fixed part. A certain amount of gas is pre-filled in the two airbags respectively, and the inner cavities of the two are selectively connected through the connecting airbag 3 arranged between the two. The auxiliary airbag and the main airbag are both made of elastic materials in the existing technology so that they can expand or contract, and the connecting airbag can also be made of elastic materials. The outside of the auxiliary airbag and the main airbag is fixedly connected to the inner wall of the corresponding fixed part of the fixing belt, such as by gluing or other methods in the existing technology. The width of the auxiliary airbag and the main airbag can be the same as the width of the corresponding fixing belt, or it can be different. It can be reasonably determined according to actual conditions, such as one-third to one-quarter of the circumference of the finger, or other quantitative relationships.
[0044] When the dressing of the present invention is placed on the part of the patient's finger or toe to be hemostatic, the main airbag is covered on the part to be hemostatic, and the auxiliary airbag is located on one side of the main airbag (see Figure 5b ), so that after the fixation belt is fixed, the main airbag is used to apply pressure to the part of the patient's finger or toe to stop bleeding, and the auxiliary airbag uses its internal gas to pressurize the main airbag: when pressurizing, the gas in the auxiliary airbag is squeezed into the main airbag so that the main airbag pressurizes the part to stop bleeding.
[0045] Among them, the main airbag adopts Figure 4b The structure shown includes a sealed main airbag body 21 and a dressing layer 22 secured to the outer surface of the main airbag body. The inner wall of the main airbag body is smooth, while the dressing layer can be made of conventional sterile dressings. Its thickness can be determined based on actual conditions. It can be secured to the outer surface of the main airbag body by gluing or other means. The dressing layer is designed to cover only the portion of the main airbag body not connected to the fixing strap.
[0046] The auxiliary airbag of the present invention is connected to the main airbag through a connecting airbag, which can be used as follows Figure 4a The structure shown includes a sealed auxiliary airbag body 41 and an adhesive layer 42 disposed on the inner wall of the auxiliary airbag body. This adhesive layer can be a pre-coated adhesive applied to the inner wall of the auxiliary airbag during manufacture. When the dressing, in which both the auxiliary airbag and the main airbag are pre-filled with gas, are in their initial, unused state, the inner wall of the auxiliary airbag near the connecting airbag and / or the inner wall of the connecting airbag are temporarily bonded together, preventing the auxiliary airbag and the main airbag from communicating with each other. When the dressing is deployed, the auxiliary airbag is squeezed, causing the gas pressure within it to overcome the adhesive coating on the bonded portions of the inner wall, temporarily separating the bonded portions and forming a channel through which the gas within the auxiliary airbag can enter the main airbag. After the gas within the auxiliary airbag is completely squeezed into the main airbag, external force can permanently bond the interiors of the auxiliary airbag and the connecting airbag together. In this way, it can prevent the gas in the auxiliary airbag from entering the main airbag too easily during storage and transportation, causing the inner wall of the auxiliary airbag to adhere, causing the main airbag to be inflated all the time and resulting in product failure. In addition, it can also effectively prevent the auxiliary airbag from being squeezed to the gas backflow in the main airbag, so that the pressure of the main airbag on the part to be hemostatic is maintained unchanged, ensuring the hemostatic effect.
[0047] Furthermore, a one-way valve can be provided on the inner wall of the connecting airbag to allow gas to flow only in one direction, from the auxiliary airbag to the main airbag. This further ensures that gas can only flow from the auxiliary airbag to the main airbag, and cannot flow back from the main airbag to the auxiliary airbag. The one-way valve can be a medical one-way valve.
[0048] It should be noted that the pressure of the pre-filled gas within the two airbags can also be predetermined based on actual conditions. During production, the sizes of the dressing and airbags can be tailored to the thickness of the fingers or toes or the desired bandage coverage. For example, large, medium, and small sizes of dressings can be designed, each with a different-sized fixing strap and airbag. When applying the dressing to stop bleeding, the dressing can be positioned on the finger or toe based on the location of the area to be stopped.
[0049] During surgery, the gas in the auxiliary airbag is usually squeezed into the main airbag to achieve the hemostasis effect on the part to be stopped. However, during surgery, there may be a situation where the gas in the auxiliary airbag enters the main airbag, but the corresponding part of the main airbag still lacks pressure on the part to be stopped. At this time, further pressure is required. The present invention folds the auxiliary airbag and the corresponding fixing belt part after the gas is squeezed out and the inner wall is permanently bonded together, and puts them on the outside of the main airbag, so that the main airbag can be squeezed from the outside of the main airbag, thereby achieving a secondary pressurization effect on the part to be stopped. Accordingly, after the auxiliary airbag is folded relative to the main airbag, the backs of the fixing straps at the corresponding positions of the two airbags will be in back-to-back contact. To prevent the auxiliary airbag fixing portion and the auxiliary airbag located on the outer ring from tilting relative to the main airbag fixing portion and the main airbag located on the inner ring, thereby affecting the pressurization and hemostasis effects, the present invention can also provide a folding adhesive tape (not shown in the figure) on the back side (the back side refers to the side facing away from the airbag) of the auxiliary airbag fixing portion and the main airbag fixing portion for bonding the two together. This adhesive tape can be a conventional adhesive tape that can bond two objects together. Correspondingly, a tearable layer can be provided on the outside of the adhesive tape. When in use, the tearable layer is peeled off to expose the adhesive surface of the adhesive tape. The two parts of the fixing tape are then bonded together back-to-back through the adhesive surfaces on the back side of the auxiliary airbag fixing portion and the back side of the main airbag fixing portion.
[0050] It can be seen that the dressing of the present invention can accurately locate the part to be hemostatic through the main airbag, and is not easy to shift during the hemostatic process, making it easy to observe the blood exudation of the wound and having a better hemostatic effect; it is simple to operate and easy to use, and does not require manpower to continuously press the part to be hemostatic manually, which can free up manpower and save time and effort; it has a simple structure and is easy to operate, and anyone can easily stop bleeding, with low processing and manufacturing costs and easy to promote and apply; it solves the problem of pressure hemostasis for fingers or toes of patients with distal limbs in orthopedics and dermatology; it reduces the difficulty of patients with postoperative wounds using existing dressings when changing dressings, and the dressings are often difficult to fall off. It solves the problem of pain in the wound caused by pulling on the finger (toe) end when removing the patient's dressing, reduces the risk of bleeding caused by rupture of capillaries due to dressing changes, and also reduces the risk of postoperative infection in patients. It is convenient for medical operations, reduces the complicated work process of medical care, reduces workload, and facilitates the entire surgical process, which brings good news to patients. Moreover, when in use, the connection length of the connectors at both ends of the fixing belt can be adjusted according to the thickness of the patient's fingers or toes, which is more comfortable to use. After the operation, the connector (such as Velcro) can be directly opened to remove the dressing, which is more convenient to use. The dressing can be sterile and disposable, and is more practical.
[0051] In addition to providing the above-mentioned dressing, the present invention also provides a method for forming a dressing for applying pressure to stop bleeding on fingers or toes, such as Figure 9 As shown, the method includes:
[0052] forming a main air bag with gas pre-inflated inside and a dressing layer on the outside;
[0053] An auxiliary airbag is formed on one side of the main airbag, the interior of which is pre-filled with gas that can be squeezed into the inner cavity of the main airbag and the inner wall of which can be fixedly connected after the gas is squeezed out;
[0054] A fixing belt is formed on the outside of the main airbag and the auxiliary airbag, wherein the inner wall is fixedly connected to the outer surface of the two and the two ends are respectively provided with connecting pieces;
[0055] After forming a fixing belt with two air bags on the inner wall, when it is necessary to apply pressure to stop bleeding on the fingers or toes, the fixing belt and its inner wall air bags are fixed to the part of the finger or toe where bleeding is to be stopped through a pair of connecting parts of the fixing belt, and the pre-filled gas in the auxiliary air bag is squeezed to allow the pre-filled gas inside to enter the main air bag and mix with the pre-filled gas in the main air bag. In cooperation with the tightening effect of the fixing belt, pressurized gas is formed to apply pressure to stop bleeding at the part where bleeding is to be stopped.
[0056] When forming a main airbag with gas pre-filled inside and a dressing layer on the outside, the main airbag body and the outer dressing layer can be fixed together by gluing or other means, and the pressure of the pre-filled gas in the main airbag body can be determined according to actual conditions.
[0057] When forming an auxiliary airbag on one side of the main airbag, which is pre-filled with gas that can be squeezed into the main airbag's inner cavity and whose inner walls can be fixedly connected after the gas is squeezed out, the adhesive layer used to connect the inner walls of the auxiliary airbag body can be a glue applied to the inner wall of the auxiliary airbag, or it can be a Velcro adhesive attached to the inner wall of the auxiliary airbag. In addition, the inner cavity of the auxiliary airbag body is connected to the inner cavity of the main airbag body through the connecting airbag. During manufacturing, the main airbag body, the auxiliary airbag body, and the connecting airbag can be integrally formed, and the pressure of the pre-filled gas in the auxiliary airbag body can be determined according to actual conditions. The methods for manufacturing each airbag can adopt existing technical methods and will not be described in detail here.
[0058] The pair of connectors at both ends of the primary and auxiliary airbag fixing portions of the fixing strap of the present invention can be male and female Velcro strips. When bonded together, the fixing strap and the two airbags located on its inner wall form a ring-shaped dressing that can be applied to the area of a finger or toe where bleeding is to be stopped. The process of using the dressing of the present invention to stop bleeding at the area of a finger or toe where bleeding is to be stopped is the same. The following describes the process using the dressing of the present invention to stop bleeding at the area of a finger where bleeding is to be stopped as an example.
[0059] Place the dressing patch under the part of the finger to be hemostatic, with the two airbags facing the skin and the fixing band facing away from the skin. Place the dressing layer on the main airbag on the part of the finger to be hemostatic, and place the auxiliary airbag beside the part to be hemostatic. That is, along the length direction of the finger, the auxiliary airbag can be located below the main airbag, and the foldable part can be located above the part to be hemostatic (see Figure 5a 、 Figure 5b );
[0060] Fold the foldable portion from the front end of the finger from bottom to top, so that the foldable portion is reversely folded from the front end of the finger from bottom to bottom and covers the part to be hemostatic, that is, wrapped around the outside of the finger (see Figure 6a 、 Figure 6b );
[0061] Place the two sides of the main airbag fixing portion of the fixing belt corresponding to the main airbag position around the finger from bottom to top and cover the upper part of the foldable portion corresponding to the hemostasis portion, and then use the first pair of connectors at both ends of the main airbag fixing portion to tie and fix this portion and the main airbag to the finger where the hemostasis portion is located (see Figure 7a 、 Figure 7b );
[0062] The two sides of the auxiliary airbag fixing part of the fixing belt corresponding to the auxiliary airbag position are respectively passed around the finger from bottom to top from both sides of the finger and covered on the lower side of the foldable part above the position corresponding to the hemostasis site, and then the auxiliary airbag and the auxiliary airbag are tied and fixed to the finger below the hemostasis site through the second pair of connectors at both ends of the auxiliary airbag fixing part (see Figure 8a 、 Figure 8b ,in, Figure 8b The width of the main airbag is basically the same as the circumference of the finger at that point. In actual application, the width of the main airbag can be smaller than the circumference of the finger);
[0063] Squeezing the auxiliary airbag causes the pre-filled gas within the auxiliary airbag body to enter the inner cavity of the main airbag body and mix with the pre-filled gas within the main airbag body. Because the main airbag fixing portion of the fixing strap has already secured the main airbag to the area of the finger to be hemostatically controlled, the auxiliary airbag body is squeezed toward the pre-filled gas within the main airbag body, causing the main airbag body to expand. With the main airbag fixing portion in place, the main airbag body can apply pressure to the area to be hemostatically controlled. After the gas within the auxiliary airbag body is completely squeezed out, the auxiliary airbag body adheres to its inner wall, preventing backflow of gas within the main airbag and allowing the main airbag to maintain the current hemostatic pressure.
[0064] If the pressurized hemostasis effect of the main airbag is not ideal after the above operation, in order to further improve the pressurized hemostasis effect of the part to be hemostatic, after the gas in the auxiliary airbag is completely squeezed out, the auxiliary airbag fixing part of the auxiliary airbag and the fixing belt can be folded over and put on the outside of the main airbag and the corresponding fixing belt, thereby further tightening the main airbag and realizing secondary pressurized hemostasis of the main airbag on the part to be hemostatic.
[0065] Correspondingly, after the auxiliary airbag is folded relative to the main airbag, the backs of the fixing belts can be pasted together back to back using the folding adhesive tape provided on the back of the fixing belts to prevent the backs of the corresponding parts of the fixing belts from detaching and affecting the pressure hemostasis effect.
[0066] Although the present invention has been described in detail above, the present invention is not limited thereto. Those skilled in the art can make modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood to fall within the scope of protection of the present invention.
