Description

Compression dressing for fingers or toes

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a dressing patch used for pressurizing and stopping bleeding on fingers or toes.

Background Art

The number of patients with malignant melanoma, nail matrix tumor, nail pigment nevus, and ingrown nails on fingers and toes is increasing year by year. Finger trauma and toe trauma are common in daily life. Fingers and toes are rich in blood supply, have many capillaries, are distributed with many nerves, and are sensitive to pain. Especially after surgery, alginate dressings are often used to cover the wound, and then fixed with bandages to stop bleeding, reduce local pain, and promote wound healing. When bandaging, it is routine to cover and pressurize with multiple layers of gauze. Since the strength of hand pressure hemostasis is different for each person, it often leads to an increase in bleeding infection. When using bandages to fix, each medical staff has different pressure strength and pressure techniques, which often leads to an increase in postoperative bleeding infection. In addition, when changing the dressing, the dressing often cannot be easily removed from the wound. When removing the dressing, it is easy to cause traction on the finger (toe) end, causing wound pain, and even causing capillary rupture and bleeding, prolonging the dressing time, increasing the workload of nurses, and increasing the risk of wound infection.

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.

DETAILED DESCRIPTION

As shown in Figures 1 to 3, they are schematic diagrams of the structure of the dressing patch for fingers and toes of the utility model when different structures are adopted. It can be seen from the figure that the dressing patch for fingers and toes of the utility model includes: a main airbag 2 pre-filled with gas inside and with a dressing layer outside; an auxiliary airbag 4 located 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 together after the gas is squeezed out; a fixing belt whose inner wall is arranged outside the main airbag and the auxiliary airbag and is respectively fixedly connected to the outer surface of the two and has connectors at both ends. Among them, when it is necessary to apply pressure to stop bleeding on the fingers or toes, the fixing belt and its inner wall airbag are fixed to the part of the finger or toe to be stopped bleeding by a pair of connectors of the fixing belt, and the auxiliary airbag is squeezed so that the pre-filled gas inside enters the main airbag and mixes with the pre-filled gas in the main airbag, and forms pressurized gas under the action of the fixing belt to apply pressure to stop bleeding on the part to be stopped bleeding.

Specifically, the dressing patch of the utility model comprises: a fixing belt with connecting pieces respectively arranged at both ends, and a main airbag and an auxiliary airbag arranged on the inner wall of the fixing belt up and down along the width direction of the fixing belt.

Among them, the fixing belt is a latex belt made of latex, including: a main airbag fixing part 12 for fixing the main airbag thereon; a foldable part 11 located on one side of the main airbag fixing part (the upper side as shown in Figure 1, Figure 5a-Figure 8b); and an auxiliary airbag fixing part 13 located on the other side of the main airbag fixing part (the lower side as shown in Figure 1).

The main airbag fixing part and the auxiliary airbag fixing part are respectively in the shape of long strips, and the two are arranged in parallel, with a part in the middle fixedly connected together (the position where they are fixedly connected together 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 (the length refers to the dimension along the up-down direction in FIG. 1, that is, when fixed on a finger, it is consistent with the extension direction of the finger length), and the width of the foldable part is less than the width of the main airbag fixing part or the auxiliary airbag fixing part (the width refers to the dimension along the left-right direction in FIG. 1, that is, when fixed on a finger 8, see FIG. 5a, it is consistent with the direction perpendicular to the extension direction of the finger length).

During design, the size of each part of the fixing belt can be determined according to actual conditions, so that after the main airbag is aimed at the part of the finger or toe to be hemostatically stopped, the length of the foldable part can at least be able to bypass the front end of the nail from below the part to be hemostatically stopped and fold over to above the part to be hemostatically stopped, that is, it can at least cover the area on the opposite side of the finger/toe to be hemostatically stopped, 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 hemostatically stopped 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.

The two ends of the main airbag fixing part and the two ends of the auxiliary airbag fixing part of the fixing belt are connected together by a pair of connectors, that is, a first pair of connectors are respectively provided at the two ends of the main airbag fixing part, and a second pair of connectors are respectively provided at the two ends of the auxiliary airbag fixing part, and the two connectors of each pair of connectors are fixed to the two ends of the corresponding fixing part by pasting or sewing or other methods in the prior art. During manufacturing, one connector is located on the inner wall (also called the front) of the corresponding fixing part, and the other connector is located on the outer wall (also called the back) of the fixing part. A pair of connectors can be a child Velcro and a mother Velcro, respectively, or other structures that can be detachably connected in the prior art.

Among them, the auxiliary airbag and the main airbag can adopt cylindrical airbags, elliptical cylindrical airbags, ellipsoidal airbags, spherical airbags, etc., which are respectively arranged at the center 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 prior art 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 being fixed together by gluing or other methods in the prior art. 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, and 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.

When the dressing of the utility model 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 fixing belt is fixed, the main airbag is used to apply pressure to the part of the patient's finger or toe to be hemostatic to stop bleeding, and the auxiliary airbag uses its internal gas to pressurize the main airbag: during pressurization, the gas in the auxiliary airbag is squeezed into the main airbag so that the main airbag pressurizes the part to be hemostatic.

The main airbag adopts the structure shown in FIG4b, including a sealed main airbag body 21 and a dressing layer 22 fixed on the outer surface of the main airbag body. The inner wall of the main airbag body is smooth, and the dressing layer can be made of a sterile dressing of the prior art, and its thickness can be determined according to actual conditions, and can be fixed on the outer surface of the main airbag body by pasting or the like, and when designed, the dressing layer can cover the part of the main airbag body that is not connected to the fixing belt.

The auxiliary airbag of the utility model is connected with the main airbag through the connecting airbag, which can adopt the structure shown in FIG. 4a, including a sealed auxiliary airbag body 41 and an adhesive layer 42 arranged on the inner wall of the auxiliary airbag body, and the adhesive layer can be a viscose pre-coated on the inner wall of the auxiliary airbag during production. When the dressing patch with gas pre-filled inside the auxiliary airbag and the main airbag is in an initial state of not being used, the inner wall of the auxiliary airbag near the connecting airbag part and/or the inner wall of the connecting airbag is temporarily bonded together, so that the auxiliary airbag and the main airbag are in a state where the inner cavity cannot be connected. When the dressing patch is to be used, the auxiliary airbag is squeezed so that the gas pressure inside it can break through the adhesive force of the viscose coated on the bonded part of the inner wall of the airbag, so that the bonded inner wall is temporarily separated so that the corresponding part of the airbag forms a channel for the gas in the auxiliary airbag to enter the main airbag. After the gas in the auxiliary airbag is completely squeezed into the main airbag, the auxiliary airbag and the connecting airbag can be permanently bonded together by external force. 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, keeping the main airbag in an expanded state and causing product failure. In addition, it can also effectively prevent the auxiliary airbag from being squeezed to the main airbag and the gas backflow, so that the pressure of the main airbag on the part to be hemostatic is maintained unchanged, ensuring the hemostatic effect.

Furthermore, a one-way valve that allows gas to flow only from the auxiliary airbag to the main airbag can be provided on the inner wall of the connecting airbag, thereby further ensuring that gas can only flow from the auxiliary airbag to the main airbag, and cannot flow from the main airbag back to the auxiliary airbag. The one-way valve can be a medical one-way valve.

It should be noted that the pressure of the pre-filled gas in the two airbags can also be predetermined according to actual conditions, and in the production process, the sizes of the dressing and the airbags can be determined according to the different thicknesses of the fingers or toes or the range of bandages required for clinical use. For example, large, medium and small dressings with different sizes of fixing straps and airbags can be designed. When the dressing is used to stop bleeding, the position of the dressing on the finger can be determined as needed according to the location of the part to be stopped on the finger or toe.

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, and the corresponding part of the main airbag still lacks pressure on the part to be stopped. In this case, further pressure is required. The utility model 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. Correspondingly, after the auxiliary airbag is folded relative to the main airbag, the backs of the fixing belts at the corresponding positions of the two airbags will be in back-to-back contact. In order to prevent the auxiliary airbag fixing part and the auxiliary airbag located in the outer circle from tilting relative to the main airbag fixing part and the main airbag located in the inner circle and affecting the pressurization and hemostasis effect, the utility model can also be provided with a folding adhesive tape (not shown in the figure) on the back side (the back side refers to the side away from the airbag) of the auxiliary airbag fixing part and the main airbag fixing part for bonding the two together. The adhesive tape that can bond two objects together in the prior art can be used. Correspondingly, a tearable layer can also 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, and the two parts of the fixing tape are bonded together back to back through the adhesive surface on the back side of the auxiliary airbag fixing part and the adhesive surface on the back side of the main airbag fixing part.

Among them, the utility model dressing patch can stop bleeding at the part to be stopped bleeding of the finger, and can also stop bleeding at the part to be stopped bleeding of the toe. The hemostasis process of the two parts is basically the same. Hereinafter, only the use of the utility model dressing patch to stop bleeding at the part to be stopped bleeding of the finger is taken as an example to describe its hemostasis process:

Place the dressing patch under the part of the finger to be hemostatic, with the two airbags facing the skin and the fixing belt facing away from the skin, so that the dressing layer on the main airbag is attached to the part of the finger to be hemostatic, and the auxiliary airbag is placed beside the part to be hemostatic, that is, along the length direction of the finger, the auxiliary airbag can be located at the lower side of the main airbag, and the foldable part is located at the upper side of the part to be hemostatic (see Figures 5a and 5b);

Fold the foldable portion from the front end of the finger from bottom to top, so that the foldable portion is folded from the front end of the finger from bottom to bottom in the opposite direction and covers the part to be hemostatic, that is, wrapped around the outside of the finger (see FIGS. 6a and 6b );

The two sides of the main airbag fixing part of the fixing belt corresponding to the main airbag position are respectively passed around the fingers from bottom to top from both sides of the fingers and cover the upper part of the foldable part corresponding to the hemostasis part, and then the main airbag and the main airbag are tied and fixed to the finger where the hemostasis part is located through the first pair of connecting pieces at both ends of the main airbag fixing part (see Figures 7a and 7b);

The two sides of the auxiliary airbag fixing part of the fixing belt corresponding to the auxiliary airbag position are respectively passed around the fingers from bottom to top from both sides of the fingers and cover the lower side of the foldable part above the position corresponding to the hemostasis part, and then the part and the auxiliary airbag are tied and fixed to the finger at the lower side of the hemostasis part through the second pair of connectors at both ends of the auxiliary airbag fixing part (see Figures 8a and 8b, wherein the width of the main airbag in Figure 8b is substantially the same as the circumference of the finger at that part, and in actual applications, the width of the main airbag may be smaller than the circumference of the finger);

The auxiliary airbag is squeezed to make the pre-filled gas in the auxiliary airbag body enter the inner cavity of the main airbag body and mix with the pre-filled gas in the inner cavity of the main airbag body. Since the main airbag fixing part of the fixing belt has fixed the main airbag at the part of the finger to be hemostatic, the auxiliary airbag body is squeezed into the pre-filled gas in the main airbag body, and the main airbag body expands. Under the fixation of the main airbag fixing part, the part to be hemostatic can be pressurized to stop bleeding. After the gas in the auxiliary airbag body is completely squeezed out, the relative inner walls of the auxiliary airbag body will stick together, thereby preventing the gas in the main airbag from backflowing and allowing the main airbag to continuously maintain the current hemostatic pressure.

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 on the part to be hemostatic, the auxiliary airbag and the auxiliary airbag fixing part of the fixing belt can be folded reversely and put on the outside of the main airbag and the corresponding fixing belt after the gas in the auxiliary airbag is completely squeezed out, thereby further tightening the main airbag and realizing secondary pressurized hemostasis of the main airbag on the part to be hemostatic.

Correspondingly, after the auxiliary airbag is folded relative to the main airbag, the backs of the fixing belts can be pasted together 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.

It can be seen that the dressing patch of the utility model can accurately locate the part to be hemostatic through the main airbag, and is not easy to shift during the hemostatic process, so it is easy to observe the blood seepage of the wound, and has a better hemostatic effect; it is simple to operate and easy to use, and there is no need for manpower to continuously press the part to be hemostatic manually, which can release manpower and save time and effort; it has a simple structure and is easy to operate, so that anyone can easily stop bleeding, and the processing and manufacturing cost is low, which is easy to promote and apply; it solves the problem of pressurized hemostasis of fingers or toes of patients with distal limbs in orthopedics and dermatology; it reduces the risk of patients' postoperative wounds using existing dressings when changing dressings and the dressings often cannot be easily removed. It solves the difficult problem of wound pain caused by pulling the finger (toe) end when removing the patient's dressing, reduces the risk of bleeding due to rupture of capillaries caused by 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 work, reduces workload, and facilitates the entire operation process, which brings good news to patients; and 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, and the dressing can be sterile and disposable, which is more practical.

Although the utility model is described in detail above, the utility model is not limited thereto, and technicians in this technical field can make modifications based on the principles of the utility model. Therefore, all modifications made according to the principles of the utility model should be understood to fall within the protection scope of the utility model.
