Description

Technical Field

[0001] The utility model relates to the technical field of medical articles, in particular to a novel hemostatic cotton patch with pressure points. Background Art

[0002] After fistula puncture, the puncture point needs to be pressed to stop bleeding. The conventional method is to use a cotton swab or hemostatic cotton to press. Among them, the cotton swab rod needs to be disassembled after pressing and fixing, which is more complicated and difficult to operate, and there is a possibility of wound infection. Pressing with hemostatic cotton is simpler and easier to operate than pressing with a cotton swab. However, the existing hemostatic cotton is a cylindrical structure and is relatively hard. The patient's fistula blood vessels are thicker than normal blood vessels and are easy to slide under the skin. When the cylindrical hemostatic cotton is pressed to stop bleeding, the blood vessels are easy to slide under the skin, causing the pressed blood vessels to shift and form subcutaneous bleeding and bruises. For example, a hemostatic patch provided by the Chinese invention patent application with application number CN202210332521.1 and a hemostatic patch with cylindrical hemostatic cotton provided by the Chinese utility model patent with application number CN202123004488.X both adopt a cylindrical hemostatic cotton structure. Therefore, although the existing hemostatic cotton has a good pressing effect, the blood vessel fixing effect is not very ideal, and there is still a possibility of pressing the blood vessels to shift and cause subcutaneous bleeding and bruises. Utility Model Content

[0003] In view of the above, it is necessary to provide a new type of hemostatic cotton patch with pressure points, which can limit the position of the blood vessels by designing the hemostatic cotton into a concave structure to frame the blood vessels, reducing the possibility of movement. This method can also increase the contact area between the hemostatic cotton and the patient's skin to achieve a better hemostatic effect, thereby reducing the chance of subcutaneous bleeding and hematoma when the needle is removed after hemodialysis.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0005] A novel hemostatic cotton patch with a pressure point comprises a base patch for pasting and fixing, hemostatic cotton and a protective film, wherein the protective film is detachably covered on the side of the base patch with adhesive, and the hemostatic cotton is arranged between the protective film and the base patch and located in the middle of the base patch; the end surface of the hemostatic cotton that is not connected to the base patch is provided with two limit strips and a central pressure block; the two limit strips are arranged at intervals along the length direction of the base patch, and the length direction of each limit strip is parallel to the width direction of the base patch; the central pressure block is arranged in the middle of the two limit strips.

[0006] Preferably, the thickness of the central compression block is smaller than the thickness of the two limiting strips.

[0007] Preferably, the novel hemostatic cotton patch with a pressure point further comprises a pressing rod, which is detachably arranged on the side of the base patch facing away from the hemostatic cotton and facing the central pressure block.

[0008] Preferably, the protective film includes two first separate films, two second separate films and one third separate film; the two first separate films are arranged on opposite sides of the two limit strips, both of which can be removably covered on the base sticker, and extend from one end of the base sticker in the length direction to the limit strip; each first separate film is connected to one end of a second separate film at one end close to the limit strip, the second separate film covers the first separate film, and the other end thereof is removably adhered to the pressing rod; the third separate film is removably covered on the hemostatic cotton, and is removably connected to the base sticker, and at least one of its two ends is removably connected to the two second separate films.

[0009] Preferably, the second split film comprises a covering section and a connecting section, the covering section covers the first split film, and the connecting section extends from the length direction of the bottom sticker to the outside of the bottom sticker and is connected to the pressing rod.

[0010] Preferably, one end of the third separate film has a sticking portion, which can be detachably adhered to a second separate film, and the sticking portion can be detachably adhered to another second separate film when not adhered to the detachable second separate film.

[0011] Preferably, a connecting seat is provided on the bottom sticker, and the pressing rod is detachably connected to the bottom sticker via the connecting seat.

[0012] Preferably, the pressing rod is detachably connected to the connecting seat via threads.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model forms a limiting groove structure on the hemostatic cotton by means of two limiting strips arranged on the hemostatic cotton. The limiting groove structure can limit the blood vessels, making it inconvenient for the blood vessels to move. At the same time, the place where the hemostatic cotton contacts the skin is not only the central compression block, but also the two limiting strips, which increases the contact area between the hemostatic cotton and the patient to a certain extent. Therefore, the structural design of the hemostatic cotton of the utility model can achieve a better hemostatic effect, thereby reducing the probability of subcutaneous bleeding and hematoma when the needle is removed after hemodialysis.

[0015] 2. The utility model facilitates pressing the puncture point by setting a pressing rod, and the structural setting of the protective film can make the bottom sticker wrap the end of the pressing rod before use to expose the central pressing block, which is convenient for positioning the puncture point and framing the blood vessel, so that the central pressing block can be accurately pressed on the puncture point, and the two limit strips can be framed on both sides of the blood vessel to improve the positioning efficiency. At the same time, it can also avoid direct contact with the bottom sticker to infect the patient's wound. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0023] See also Figure 1 In a preferred embodiment of the utility model, a new type of hemostatic cotton patch with a pressure point includes a base patch 1 for pasting and fixing, hemostatic cotton 2 and a protective film, wherein the protective film is detachably covered on the side of the base patch 1 with adhesive, and the hemostatic cotton 2 is arranged between the protective film and the base patch 1 and located in the middle of the base patch 1; the end surface of the hemostatic cotton 2 not connected to the base patch 1 is provided with two limiting strips 3 and a central compression block 4; the two limiting strips 3 are arranged at intervals along the length direction of the base patch 1, and the length direction of each limiting strip 3 is parallel to the width direction of the base patch 1; the central compression block 4 is arranged in the middle of the two limiting strips 3; preferably, the thickness of the central compression block 4 is less than the thickness of the two limiting strips 3.

[0024] The utility model positions and compresses the puncture point through the central compression block 4 on the hemostatic cotton 2, and forms a limiting groove structure by arranging two limiting strips 3 on the hemostatic cotton 2. The limiting groove presents a concave structure when the hemostatic cotton patch is used, and the internal fistula blood vessel can be framed inside to prevent the blood vessel from moving during the hemostatic compression process. At the same time, during the hemostatic pressing process, not only the central compression block 4 contacts the patient's skin, but the two limiting strips 3 also contact the patient's skin, increasing the contact area between the hemostatic cotton 2 and the patient's skin, thereby achieving a better hemostatic effect and reducing the probability of subcutaneous bleeding and hematoma when the patient removes the needle after hemodialysis. Therefore, the hemostatic cotton patch of the utility model has a good hemostatic effect.

[0025] See also Figure 2-4 In the second embodiment of the utility model, the new hemostatic cotton patch with a pressure point also includes a pressing rod 5, which is detachably arranged on the side of the base patch 1 away from the hemostatic cotton 2 and facing the central compression block 4, so as to contact the hemostatic cotton patch through the pressing rod 5, and facilitate pressing the puncture point to stop bleeding, thereby improving the hemostatic effect and stopping bleeding.

[0026] Furthermore, in order to facilitate the use of the pressing rod 5 and avoid the hemostatic cotton 2 being insufficiently exposed during the pressing and positioning process, thereby affecting the accurate pressing of the puncture point, the protective film includes two first split films 7, two second split films 8 and a third split film 9; the two first split films 7 are arranged on opposite sides of the two limiting strips 3, and both can be removably covered on the base sticker 1, and extend from one end of the base sticker 1 in the length direction to the limiting strip 3; each first split film 7 is connected to one end of a second split film 8 at one end close to the limiting strip 3, and the second split film 8 is covered on the first split film 7, and the other end thereof is removably pasted on the pressing rod 5. Specifically, the second split film 8 includes a covering section and a connecting section, and the covering section is covered on the first split film 7, and the connecting section extends from the length direction of the base sticker 1 to the outside of the base sticker 1 and is connected to the pressing rod 5; the third split film 9 is removably covered on the hemostatic cotton 2, and is removably connected to the base sticker 1, and at least one end of its two ends is removably connected to the two second split films 8.

[0027] That is, the first separation film 7 is used to protect the portion from the end of the bottom sticker 1 to the limit strip 3, and the second separation film 8 is used to fold the portion from the bottom sticker 1 to the limit strip 3 upward to expose the portion of the hemostatic cotton 2. The second separation film 8 also facilitates the first separation film 7 to tear off the bottom sticker 1, and the third separation film 9 is used to protect the hemostatic cotton 2 to prevent the hemostatic cotton 2 from being contaminated. In other words, through the structural setting of the above-mentioned protective film, the bottom sticker 1 can form a structural form that wraps the end of the pressing rod 5, preventing the two ends of the bottom sticker 1 in the length direction from sagging and affecting the precise positioning and pressing of the puncture point. At the same time, this design method also facilitates the tearing off of the protective film, reducing the possibility of the bottom sticker 1 and the hemostatic cotton 2 being contaminated.

[0028] Further preferably, one end of the third separate film 9 has an adhesive portion, which can be detachably adhered to a second separate film 8. When the adhesive portion is not adhered to the detachable second separate film 8, it can also be detachably adhered to another second separate film 8. That is, after one end of the third separate film 9 is torn off to expose the hemostatic cotton 2, it can also be adhered to the second separate film 8 through the adhesive portion. This prevents the second separate film 8 connected to the other end from being torn off when the third separate film 9 is torn off. At the same time, it can be convenient for the hemostatic cotton 2 to be opened and then covered again for protection due to human reasons such as insufficient preparation and misoperation, and then torn off when it is actually used, thereby protecting the hemostatic cotton 2 from contamination.

[0029] In addition, preferably, a connection seat 6 is provided on the bottom sticker 1, and the pressing rod 5 is detachably connected to the bottom sticker 1 through the connection seat 6. The setting of the connection seat 6 can quickly position and apply pressure when the pressing rod 5 needs to be pressed again after being removed. More preferably, the pressing rod 5 is detachably connected to the connection seat 6 through a thread, so that the pressing rod 5 can be easily disassembled and assembled on the connection seat 6. The connection seat 6 is made of a material with low hardness, and it can be bent when the bottom sticker 1 is attached to the human body.

[0030] Finally, if instructions are required, in order to facilitate checking whether bleeding occurs during the hemostasis process, the base sticker 1 is preferably made of a transparent material.

[0031] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
