Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary products, in particular to a filled hemostatic dressing. Background Art
[0002] In daily life, people often suffer from small-area bleeding due to trauma. In order to stop bleeding from wounds, people generally use hemostatic patches to stick on the wounds. However, the existing commonly used hemostatic patches are generally only stuck on the wounds, lacking a certain pressure on the wounds, thereby affecting the hemostatic effect and the speed of hemostasis of the hemostatic patches. Once the hemostasis of the wounds is not handled well, infection is prone to occur, which is not conducive to the healing of the wounds. In addition, in clinical work in hospitals, patients often need to be drawn for blood tests or intravenous injection treatments. After the blood draw or intravenous injection is completed, the needle eye will bleed. In order to stop bleeding from the needle eye, the traditional method is to press the sterile cotton ball after disinfection on the needle eye. However, due to uneven force, the sterile cotton ball is easy to deviate from the needle eye, thereby causing the needle eye to bleed again. At the same time, if the pressing force is improper, or the pressing time is not enough, it is easy to cause the needle eye to bleed again, the hemostatic effect is poor, and it is easy to cause the needle eye to be infected, so that subcutaneous bleeding causes cyanosis and swelling, affecting the healing of the needle eye. Furthermore, when the needle hole appears at a position that the patient cannot press with his fingers or the patient has difficulty pressing, or there are too many acupuncture sites, another person is required to press specifically, which is inconvenient.
[0003] The patent with publication number CN219375178U discloses a hemostatic dressing, including a hemostatic dressing body, one side of which is provided with a surrounding belt for surrounding a bleeding point limb to compress and fix the hemostatic dressing body, the upper surface of which is provided with a pressing airbag for pressing and stopping bleeding at the bleeding point, and the upper surface of which is provided with a downward pressing mechanism for providing downward pressure to the pressing airbag for pressing and stopping bleeding. In the hemostatic dressing, the hemostatic cotton pad and the glue coating are provided on the lower surface of the hemostatic dressing body, so that the hemostatic dressing body can be attached to the bleeding point to stop bleeding, and the pressing airbag provided on the hemostatic dressing body is coated and attached by the first pressing belt and the second pressing belt, so that the pressing airbag can be pressed downward to stop bleeding, and the downward pressing air cushion provided on the surrounding belt can provide further squeezing and stopping bleeding for the pressing airbag.
[0004] In actual use, such hemostatic patches as those mentioned above cannot accurately control the extrusion force, which may easily lead to the force being too small to achieve the purpose of hemostasis, or the blood supply may be affected due to excessive force. Therefore, it is necessary to constantly adjust the extrusion force manually, which is very inconvenient to use. The force cannot be adjusted according to the bleeding situation, resulting in a relatively poor hemostatic effect. Summary of the invention
[0005] The utility model aims to provide a filled hemostatic dressing, which overcomes the problem in the prior art that the extrusion force of the hemostatic dressing is difficult to control and needs to be adjusted manually, which is inconvenient to use and leads to poor hemostatic effect.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problems is:
[0007] A filled hemostatic dressing is designed with double extrusion protection. During the hemostasis process, the liquid-absorbing expansion material can be expanded by exuding blood, and the extrusion block is forced to press the bleeding position to stop bleeding. When the expansion and extrusion effect is not ideal, the pressure belt is used to achieve secondary auxiliary extrusion of the bleeding position until the purpose of hemostasis is achieved, thereby achieving accurate and rapid hemostasis at the bleeding position and achieving a better hemostasis effect. The specific plan is as follows:
[0008] A filled hemostatic dressing comprises an dressing body, and a first binding strap and a second binding strap arranged at the left and right ends of the dressing body, wherein a squeezing block is slidably connected to the bottom of the dressing body;
[0009] The space between the extrusion block and the dressing body is filled with a liquid-absorbing swelling object, and the liquid-absorbing swelling object is sealed in the extrusion block through a hemostatic cotton patch.
[0010] Preferably, a filling cavity is provided in the applicator body, a guide slide channel is provided through the bottom of the filling cavity, the longitudinal section of the extrusion block is an I-shaped hollow structure, the middle part of the extrusion block is slidably connected to the guide slide channel, and the upper end is located in the filling cavity.
[0011] Preferably, the longitudinal section of the hemostatic cotton patch is an inverted T-shaped structure, the top edge of the hemostatic cotton patch is adhered to the bottom of the extrusion block, and the middle part is embedded in the extrusion block.
[0012] Preferably, a first Velcro is provided on the inner side of the free end of the first strap, and a second Velcro is provided on the outer side of the free end of the second strap, and the second Velcro is adhered to the first Velcro.
[0013] Preferably, a first pressure belt and a second pressure belt are respectively provided at the middle of the outer sides of the first and second pressure belts, a third Velcro is provided at the inner side of the free end of the first pressure belt, and a fourth Velcro is provided at the outer side of the free end of the second pressure belt.
[0014] Preferably, an extrusion airbag is provided on the inner side of the free end of the second pressurizing belt, and the extrusion airbag abuts against the outer side of the application body.
[0015] Preferably, the liquid-absorbing and swelling material is highly water-absorbent resin particles.
[0016] The beneficial effects of the utility model are:
[0017] 1. The utility model has straps on both sides of the dressing body, which can fix the dressing body at the bleeding position. The liquid-absorbing swelling material in the dressing body pushes the squeezing block to squeeze the bleeding position, thereby achieving the purpose of squeezing hemostasis. The hemostasis process does not require manual control of the squeezing force, and the squeezing force can be controlled by the bleeding situation itself, and the effect is very significant.
[0018] 2. The utility model has a double squeezing function. When the pressure caused by the expansion of the liquid-absorbing swelling material in the dressing body cannot meet the force required for hemostasis, it can also be squeezed for the second time by the pressure belt to achieve the purpose of rapid hemostasis.
[0019] 3. The liquid-absorbing expansion object of the utility model can expand rapidly with the amount of blood sucked in, and timely push the squeezing block to squeeze the bleeding position. After the bleeding is stopped, the liquid-absorbing expansion object will not be able to continue to absorb blood and expand, and the hemostasis function can be achieved just right.

[0028] like Figure 1-3 As shown, the utility model provides a filled hemostatic dressing, including an dressing body 1, and a first strap 2 and a second strap 3 arranged at the left and right ends of the dressing body 1. The dressing body 1 can be fixed at the bleeding position by the first strap 2 and the second strap 3. A squeezing block 5 is slidably connected to the bottom of the dressing body 1. A liquid-absorbing swelling material 6 is filled between the squeezing block 5 and the dressing body 1. The liquid-absorbing swelling material 6 is sealed in the squeezing block 5 by a hemostatic cotton patch 4. By covering the bleeding position with the hemostatic cotton patch 4 and sucking blood into the liquid-absorbing swelling material 6 through the hemostatic cotton patch 4, the liquid-absorbing swelling material 6 expands and pushes the squeezing block 5 to squeeze the bleeding position.
[0029] In the above scheme, a filling cavity 11 is provided in the dressing body 1, and a guide channel 12 is provided through the bottom of the filling cavity 11. The longitudinal section of the extrusion block 5 is an I-shaped hollow structure. The middle part of the extrusion block 5 is slidably connected with the guide channel 12, and the upper end is located in the filling cavity 11.
[0030] As an optimized technical solution of the utility model, the extrusion block 5 is an I-shaped hollow structure, and its upper side is slidably connected in the filling cavity 11, so that the filling cavity 11 is communicated with the interior of the extrusion block 5, so that the liquid-absorbing expansion material 6 can be filled in the filling cavity 11 and the extrusion block 5, and the sliding connection relationship between the middle part of the extrusion block 5 and the guide channel 12 can push the extrusion block 5 to slide out under the expansion of the liquid-absorbing expansion material 6, so that the extrusion block 5 is pressed on the bleeding position.
[0031] In the above solution, the longitudinal section of the hemostatic cotton patch 4 is an inverted T-shaped structure, the top edge of the hemostatic cotton patch 4 is adhered to the bottom of the extrusion block 5, and the middle part is embedded in the extrusion block 5.
[0032] As an optimized technical solution of the utility model, the hemostatic cotton patch 4 is made of a water-absorbent material, which can absorb the blood flowing out of the bleeding site into the position of the liquid-absorbing swelling object 6 filled in the filling cavity 5, so that the liquid-absorbing swelling object 6 can absorb liquid and expand, and squeeze and push the squeezing block 5 to achieve the purpose of squeezing hemostasis.
[0033] In the above solution, a first Velcro 21 is provided on the inner side of the free end of the first strap 2 , and a second Velcro 31 is provided on the outer side of the free end of the second strap 3 , and the second Velcro 31 is adhered to the first Velcro 21 .
[0034] As an optimized technical solution of the utility model, the first Velcro 21 and the second Velcro 31 are adhered to each other, so that the dressing body 1 can be firmly bound to the bleeding position through the first strap 2 and the second strap 3.
[0035] In the above scheme, a first pressure belt 22 and a second pressure belt 32 are respectively provided in the middle of the outer sides of the first strap 2 and the second strap 3, a third Velcro 221 is provided on the inner side of the free end of the first pressure belt 22, and a fourth Velcro 321 is provided on the outer side of the free end of the second pressure belt 32.
[0036] As an optimization technical solution of the utility model, the first pressure belt 22 and the second pressure belt 32 are connected together by sticking the third Velcro 221 and the fourth Velcro 321 together, so that the dressing body 1 can be pressurized so that the dressing body 1 can have enough pressure to squeeze the bleeding position.
[0037] In the above solution, an extrusion airbag 322 is provided inside the free end of the second pressurizing belt 32 , and the extrusion airbag 322 abuts against the outside of the dressing body 1 .
[0038] As an optimization technical solution of the utility model, gas can be filled into the squeezing airbag 322 to make the squeezing airbag 322 larger, and the squeezing airbag 322 is used to squeeze the dressing body 1, so as to further squeeze the bleeding position, so as to achieve rapid hemostasis.
[0039] In the above scheme, the liquid-absorbing swelling material 6 is a highly absorbent resin particle, which can fully absorb the water in the blood, and then can expand rapidly after absorbing the water, so that the highly absorbent resin particle becomes larger, and then can effectively squeeze and push the extrusion block 5, so that it has enough pressure to compress the bleeding position to achieve the purpose of hemostasis.
[0040] Specific implementation cases:
[0041] When it is necessary to apply pressure to the bleeding site to stop bleeding, first align the dressing body 1 with the bleeding site, fix the dressing body 1 by the first strap 2 and the second strap 3, and then fix the free ends of the first strap 2 and the second strap 3 by the mutual adhesion of the first Velcro 21 and the second Velcro 31, thereby fixing the dressing body 1 at the bleeding site.
[0042] When the dressing body 1 covers the bleeding position, the flowing blood can be absorbed into the liquid-absorbing swelling material 6 in the filling cavity 11 through the hemostatic cotton patch 4, so that the liquid-absorbing swelling material 6 absorbs liquid and expands, and then can push the squeezing block 5 to slide outward along the guide channel 2. As the amount of bleeding increases, the squeezing block 5 can be gradually pushed to slide until the squeezing block 5 is tightly pressed on the bleeding position to achieve the purpose of compression and hemostasis. If bleeding continues during this process, the liquid-absorbing swelling material 6 can continue to absorb liquid and expand, pushing the squeezing block 5 to squeeze the bleeding position, increasing the squeezing force on the bleeding position until the bleeding stops. If the bleeding stops, the liquid-absorbing swelling material 6 cannot absorb liquid, causing the squeezing block 5 to stop sliding, and the squeezing force is maintained to squeeze the bleeding position.
[0043] Finally, if the liquid-absorbing expansion material 6 is expanded to the maximum extent but still cannot achieve the purpose of compressing and stopping bleeding, the first pressure belt 22 and the second pressure belt 32 can be used to further squeeze the dressing body 1. By filling gas into the squeezing airbag 322 between the two, the bleeding position can be compressed twice through the dressing body 1, and then there can be enough squeezing force to compress the bleeding position to stop bleeding.
[0044] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
