Abstract
Description
Technical Field
[0001] This utility model specifically relates to an emergency anti-infection multi-circumferential bandage hemostatic bandage, belonging to the field of medical device technology. Background Technology
[0002] For deep and open wounds, managing significant bleeding in emergency situations is challenging. If bandages, gauze, gloves, or other items used during bandaging are contaminated with the blood of a previous patient, although the virus quickly becomes inactive in a dry environment, the blood may not have dried completely. Furthermore, these items may not quickly suppress bleeding during bandaging, posing a risk of infection if the operator comes into contact with the skin or wound of the person being bandaged. For example, when a hepatitis B patient experiences significant bleeding from an injury, the blood is infectious. Rapid and urgent contact with the blood of a hepatitis B patient, especially through broken skin or mucous membranes, carries a risk of hepatitis B virus infection. This is particularly true if the contact person has broken skin, such as wounds, ulcers, or mucous membrane damage, allowing the hepatitis B virus to enter the body and cause infection.
[0003] Methods for stopping bleeding from external injuries generally include applying pressure, bandaging, and using medication, but these methods have the following drawbacks: 1. The hemostatic effect of pressure is limited. For larger wounds or cases with a large amount of bleeding, the effect of pressure to stop bleeding is often not ideal and it is difficult to completely control the bleeding.
[0004] 2. There is a problem of blood seepage when bandaging to stop bleeding. If the wound area is large or the wound location is irregular, it is difficult to completely cover the wound when bandaging, resulting in some blood still seeping out.
[0005] 3. Drug-induced hemostasis has limitations. For wounds with large amounts of bleeding, the effect of local drug hemostasis is limited, and there may be seepage of blood at the edges. Utility Model Content

The non-woven fabric sheet is rectangular, and a central connecting part is provided in the middle of the non-woven fabric sheet. The non-woven fabric sheet is connected to the top inner wall and the bottom inner wall of the outer dressing sleeve through the central connecting part. The interior of the outer dressing sleeve is divided into a first cavity and a second cavity by the central connecting part. Cable ties are inserted into the first cavity. The first cable tie is connected to one side of the non-woven fabric sheet. The second cable tie is inserted into the second cavity and is connected to the other side of the non-woven fabric sheet. When the first and second cable ties move towards each other near the central connecting part, the first and second cable ties are wrapped around the two sides of the non-woven fabric sheet, and the non-woven fabric sheet is in a narrow usage state with absorption on both sides. When the first and second cable ties move away from the central connecting part, the non-woven fabric sheet is in a wide usage state with spread out on both sides.

[0010] As a preferred embodiment: when the direction of the bandaged wound is consistent with the length direction of the central connecting part, the first connecting end of the first cable tie and the second insertion end of the second cable tie are detachably connected.
[0011] As a preferred embodiment: when the direction of the bandaged wound is consistent with the width direction of the central connecting part, the first connecting end of the first cable tie and its first insertion end are detachably connected, and the second connecting end of the second cable tie and its second insertion end are detachably connected.
[0012] As a preferred option, two barrier cotton blocks are provided on the bottom outer wall of the external dressing sleeve, and the two barrier cotton blocks are respectively located at both ends of the bottom connecting part.
[0013] As a preferred embodiment: both the first and second cable ties are nylon cable ties, the first insertion end of the first cable tie is a first square block, the first connecting end of the first cable tie is a flexible rope end, and the first cable tie is also machined with multiple reverse snap teeth, the first square block is machined with insertion holes, and the inner wall of the insertion holes is machined with slots.

[0016] The beneficial effects of this utility model are as follows: This invention is an on-demand emergency hemostasis structure that allows for selection of bandaging methods based on the bleeding location. The combination of a first and second cable ties enables on-demand pressure hemostasis on both sides or ends of the bleeding limb. Simultaneously, an external dressing is used for bandaging hemostasis. The internal dressing absorbs blood seepage from the wound, keeping it dry and clean, while the outer transparent membrane effectively prevents blood leakage through a seal, reducing the risk of infection and facilitating observation of blood seepage. This invention not only combines the advantages of pressure hemostasis and bandaging hemostasis but also enhances hemostasis strength at the circumferential edges of the bleeding site through adjustable cable ties and a sealed transparent membrane. It is specifically designed for use in environments with infectious risks and can also be used in emergency situations involving unknown blood conditions, improving emergency hemostasis efficiency and reducing the risk of infection. This invention helps curb the spread of bloodborne infectious diseases and reduces the probability of infection. Attached Figure Description

Detailed Implementation
[0019] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0020] Specific Implementation Method 1: Combining 1 to Figure 8This embodiment describes an emergency anti-infection multi-circumferential bandage that includes an outer dressing 1 and a centrally positioned self-extending hemostatic patch 2. The outer dressing 1 is a rectangular sleeve, and the centrally positioned self-extending hemostatic patch 2 is inserted inside the outer dressing 1. The centrally positioned self-extending hemostatic patch 2 includes a first cable tie 2-1, a second cable tie 2-2, and a non-woven fabric sheet 2-3. The non-woven fabric sheet 2-3 is a rectangular piece of fabric, and a central connecting part 4 is provided in the middle of the non-woven fabric sheet 2-3. The non-woven fabric sheet 2-3 is connected to the top inner wall and the bottom inner wall of the outer dressing 1 through the central connecting part 4. The interior of the outer dressing 1 is divided into a first cavity 5 and a second cavity 6 by the central connecting part 4. The first cable tie 2-1 is inserted into the first cavity 5, and the first cable tie 2-1 is connected to the non-woven fabric sheet 2-3. The first cavity 5 is a flexible cavity that provides movement and limiting space for the first cable tie 2-1. The second cable tie 2-2 is inserted into the second cavity 6, which is also a flexible cavity that provides movement and limiting space for the second cable tie 2-2. The second cable tie 2-2 is connected to the other side of the non-woven fabric sheet 2-3. When the first cable tie 2-1 and the second cable tie 2-2 move towards each other closer to the central connecting part 4, the first cable tie 2-1 and the second cable tie 2-2 are respectively wrapped around the two sides of the non-woven fabric sheet 2-3, and the non-woven fabric sheet 2-3 is in a narrow usage state with absorption on both sides. When the first cable tie 2-1 and the second cable tie 2-2 move away from the central connecting part 4, the non-woven fabric sheet 2-3 is in a wide usage state with unfolded on both sides.
[0021] Among them, the external dressing sleeve 1 is a flat flexible sleeve. A top connecting part 7 is provided on the top inner wall of the external dressing sleeve 1 along its length direction, and a bottom connecting part 8 is provided on the bottom inner wall of the external dressing sleeve 1 along its length direction. The top connecting part 7 is connected to the bottom connecting part 8 through the middle connecting part 4. The top connecting part 7, the middle connecting part 4 and the bottom connecting part 8 are all long strip connecting strips. The top connecting part 7 is located at the top center of the outer dressing sleeve 1, the middle connecting part 4 is located at the center of the non-woven fabric sheet 2-3, and the bottom connecting part 8 is located at the bottom center of the outer dressing sleeve 1. In this embodiment, the top connecting part 7, the middle connecting part 4, and the bottom connecting part 8 are stamped to form a multi-layer composite structure. The top connecting part 7, the middle connecting part 4, and the bottom connecting part 8 are each processed with multiple small absorbent cavities, similar to a sponge structure, which is conducive to concentrated absorption of blood volume. The middle position of the top connecting part 7, the middle connecting part 4, and the bottom connecting part 8 helps to reduce the probability of direct contact, and the edge operator can quickly operate at the edge of the outer dressing sleeve 1.
[0022] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. In this implementation method, the two ends of the first cable tie 2-1 are the first insertion end and the first connection end, respectively, and the two ends of the second cable tie 2-2 are the second insertion end and the second connection end, respectively. The first insertion end of the first cable tie 2-1 and the second connection end of the second cable tie 2-2 are located on the same side of the non-woven fabric sheet 2-3, and the first connection end of the first cable tie 2-1 and the second insertion end of the second cable tie 2-2 are located on the same side of the non-woven fabric sheet 2-3.
[0023] Specific Implementation Method Three: This implementation method is a further limitation of Specific Implementation Method One or Two. The first cable tie 2-1 and the second cable tie 2-2 have two wrapping methods, combined with... Figure 6 As shown, in one type of bandaging method, the connection process is as follows: when the direction of the bandaged wound is aligned with the length direction of the central connecting part 4, the first connecting end of the first cable tie 2-1 and the second insertion end of the second cable tie 2-2 are detachably connected. Wherein, "aligning" means that the direction of the bandaged wound is aligned with the length direction of the central connecting part 4, or the included angle between them is less than 60 degrees.
[0024] The usage process of this implementation method: When this utility model is applied to a wound on the limbs, especially a long and narrow wound, ensure that the length of the outer dressing 1, i.e., the length of the central connecting part 4, is close to the length of the wound. This means ensuring that the overlapping area of the top connecting part 7, the bottom connecting part 8, and the central connecting part 4 covers the main part of the wound. After applying the outer dressing 1 to the wound, if there is significant bleeding, appropriately rotate and move the first cable ties 2-1 and the second cable ties 2-2 outwards to ensure that the coverage area of the non-woven fabric sheet 2-3 matches the wound area. This adapts the double-layer structure of the outer dressing 1 to the wound. The non-woven fabric sheet 2-3 in the central position forms a three-layer dressing structure. After the outer dressing sleeve 1 with the central self-extending hemostatic pads 2 on both sides is wrapped around the corresponding position of the upper or lower limb, the first connecting end of the first cable tie 2-1 and the second insertion end of the second cable tie 2-2 are connected to form the first locking structure wrapped around the limb. The first insertion end of the first cable tie 2-1 and the second connecting end of the second cable tie 2-2 are connected to form the second locking structure wrapped around the limb, thus forming the effect of limiting the blood flow area on both sides and achieving the effect of pressing and limiting the bleeding area.
[0025] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One or Two. The first cable tie 2-1 and the second cable tie 2-2 have two wrapping methods, combined with... Figure 7As shown, in another bandaging method, when the direction of the bandaged wound tends to be consistent with the width direction of the central connecting part 4, the first connecting end of the first cable tie 2-1 is detachably connected to its first insertion end, and the second connecting end of the second cable tie 2-2 is detachably connected to its second insertion end.
[0026] The usage process of this implementation method: When applying this invention to wounds on the limbs, if the wound opening is wide and short, ensure that the length direction of the outer dressing 1, i.e., the length direction of the central connecting part 4, is close to the width direction of the wound. This means ensuring that the overlapping area of the top connecting part 7, the bottom connecting part 8, and the central connecting part 4 covers the main part of the wound. After applying the outer dressing 1 to the wound, if there is significant bleeding, appropriately rotate and move the first cable ties 2-1 and the second cable ties 2-2 outwards to ensure that the coverage area of the non-woven fabric sheet 2-3 matches the wound area, and then fit the outer dressing. The double-layer structure of the outer dressing 1 and the non-woven fabric sheet 2-3 in the middle position form a three-layer dressing structure. After the outer dressing 1 with the self-extending hemostatic pads 2 in the middle is wrapped around the corresponding position of the upper or lower limb, the first connecting end of the first cable tie 2-1 and its first insertion end are connected to form the first locking structure wrapped around the limb. The first connecting end of the first cable tie 2-1 and its first insertion end are connected to form the second locking structure wrapped around the limb, thus forming the effect of limiting the blood flow area on both sides and achieving the effect of pressing and limiting the bleeding area.
[0027] Specific Implementation Method Five: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, or Four, combined with... Figure 3 As shown, two barrier cotton blocks 9 are provided on the bottom outer wall of the external dressing 1, and the two barrier cotton blocks 9 are respectively located at both ends of the bottom connecting part 8. The two barrier cotton blocks 9 directly contact the wound and play a role in blocking blood at both ends of the bottom connecting part 8. The length of the barrier cotton blocks 9 can be adapted to the width of the bottom connecting part 8 and the width of the external dressing 1, with the maximum value being the width of the external dressing 1 and the minimum value being the width of the bottom connecting part 8.
[0028] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. The first cable tie strip 2-1 and the second cable tie strip 2-2 are both nylon cable ties. The first insertion end of the first cable tie strip 2-1 is a first square block 2-1-1, and the first connecting end of the first cable tie strip 2-1 is a flexible rope end 2-1-2. The first cable tie strip 2-1 is also machined with a plurality of reverse snap teeth 2-1-3. When the first cable tie strip 2-1 is connected by itself, the first square block 2-1-1 is machined with an insertion hole 2-1-4 that cooperates with the flexible rope end 2-1-2. The inner wall of the insertion hole 2-1-4 is machined with a groove that cooperates with the plurality of reverse snap teeth 2-1-3. When the first cable tie 2-1 is connected to the second cable tie 2-2, the structure of the flexible rope end 2-1-2 can be twisted to achieve a stable connection with the adjacent second cable tie 2-2. The use of nylon cable ties can quickly and accurately control the binding force to achieve effective pressure hemostasis.
[0029] In this embodiment, the structure of the second cable tie 2-2 is the same as that of the first cable tie 2-1.
[0030] Specific implementation method seven: Combining Figure 2 and Figure 3 As shown, the emergency anti-infection multi-circumferential bandage hemostatic bandage in this embodiment includes an outer dressing sleeve 1, a centrally placed self-extending hemostatic patch 2 on both sides, and a sealing film 3. The outer dressing sleeve 1 is provided with a sealing film 3, which is an existing medical transparent film. The sealing film 3 includes a transparent film 3-1 and a square ring tape 3-2. The bottom surface of the transparent film 3-1 is placed on the outer dressing sleeve 1, and the bottom surface of the transparent film 3-1 is provided with a square ring tape 3-2. The outer dressing sleeve 1 is placed inside the square ring tape 3-2.
[0031] The external dressing sleeve 1 is a non-woven fabric sleeve. A centrally positioned, self-extending, bilaterally extending hemostatic patch 2 is disposed inside the external dressing sleeve 1. A sealing film 3 is disposed on the outer layer of the external dressing sleeve 1. The centrally positioned, self-extending, bilaterally extending hemostatic patch 2 includes a first cable tie 2-1, a second cable tie 2-2, and a non-woven fabric sheet 2-3. The non-woven fabric sheet 2-3 is positioned at its center along the length of the external dressing sleeve 1 inside the external dressing sleeve 1. A first cable tie 2-1 is disposed on one side edge of the non-woven fabric sheet 2-3. A second cable tie 2-2 is provided on the other side edge. When the non-woven fabric sheet 2-3 is in the contracted state, the first cable tie 2-1 rolls one side edge of the non-woven fabric sheet 2-3 inward, and the second cable tie 2-2 rolls the other side edge of the non-woven fabric sheet 2-3 inward. When the non-woven fabric sheet 2-3 is in the unfolded state, the first cable tie 2-1 unfolds the rolled-up side of the non-woven fabric sheet 2-3 outward, and the second cable tie 2-2 unfolds the rolled-up other side of the non-woven fabric sheet 2-3 outward.
[0032] Adjust the spacing between the first cable tie 2-1 and the second cable tie 2-2 according to the extent of the patient's wound. Then wrap the external dressing 1 around the wound and tie the first cable tie 2-1 and the second cable tie 2-2 around the circumference of the patient's limb to achieve the purpose of pressure hemostasis. The external dressing 1 achieves the purpose of wrapping and hemostasis. At the same time, the sealing film 3 seals the external dressing 1 to prevent the blood seeping from the external dressing 1 from causing infection.
[0033] When the external dressing 1 is wrapped around the wound, the transparent film 3-1 completely covers the external dressing 1 and is attached to the surface of the injured person's skin by the square ring tape 3-2, effectively sealing the external dressing 1 and preventing blood from seeping out of the external dressing 1, thus preventing the leakage of infectious blood.
[0034] Working principle of this implementation method: This utility model is applied to the wound on the limbs according to the specific emergency situation, ensuring that the length direction of the outer dressing 1, that is, the length direction of the central connecting part 4, tends to the length direction of the wound. Specifically, it ensures that the overlapping area of the top connecting part 7, the bottom connecting part 8, and the central connecting part 4 covers the main part of the wound. After applying the outer dressing 1 to the wound, if the bleeding is significant, the first cable tie 2-1 and the second cable tie 2-2 are appropriately rotated and moved outwards, so that the coverage area of the non-woven fabric piece 2-3 is adapted to the wound area. This adapts the double-layer structure of the outer dressing 1 and the non-woven fabric piece 2-3 in the central position to form a three-layer structure. The layered dressing structure involves wrapping the outer dressing sleeve 1 with the centrally positioned self-extending hemostatic pads 2 around the corresponding position on the upper or lower limb. Then, the first connecting end of the first cable tie 2-1 and the second insertion end of the second cable tie 2-2 are connected to form a first locking structure wrapped around the limb. The first insertion end of the first cable tie 2-1 and the second connecting end of the second cable tie 2-2 are connected to form a second locking structure wrapped around the limb, thus creating a blood flow area defined on both sides. A sealing film 3 is then wrapped around the limb, with at least one wrap around the limb circumferentially to achieve an external tightening effect.
[0035] Specific implementation method eight: Combination Figure 1 and Figure 4 As shown, in this embodiment, the two sides of the top connecting part 7 are respectively the first tearing part 10, and the two sides of the bottom connecting part 8 are respectively the second tearing part 11. The first tearing part 10 and the second tearing part 11 are both existing linear indentations. The outer dressing 1 itself is a coaxial sleeve made of multiple layers of non-woven fabric. By setting the first tearing part 10 and the second tearing part 11, it is possible to peel off an appropriate number of layers of non-woven fabric from the multiple layers of non-woven fabric, extending the coverage area of the outer dressing 1, which is suitable for secondary expansion bandaging of open wounds.
[0036] Specific Implementation Method Nine: Combining Figure 9As shown, the emergency anti-infection multi-circumferential bandage hemostatic bandage in this embodiment includes an outer dressing sleeve 1 and a centrally placed self-extending hemostatic patch 2 on both sides. The only difference is the arrangement position of the first bandage strip 2-1 and the second bandage strip 2-2. It can only realize the connection process of the first bandage strip 2-1 and the second bandage strip 2-2 themselves. Other unmentioned structures and connection relationships are the same as those in specific embodiments one, two, three, four, five, six, seven or eight.
[0037] Working principle: Adjust the positions of the first cable tie strip 2-1 and the second cable tie strip 2-2 according to the size of the wound. When the wound is small, roll the first cable tie strip 2-1 and the second cable tie strip 2-2 towards the middle to shorten the distance between them. When the wound is large, unfold the first cable tie strip 2-1 and the second cable tie strip 2-2 to the sides to increase the distance between them.
[0038] After adjusting the positions of the first cable tie 2-1 and the second cable tie 2-2, wrap the external dressing 1 between the first cable tie 2-1 and the second cable tie 2-2 around the wound. Then, tie the first cable tie 2-1 and the second cable tie 2-2 around the limb and tighten them to achieve the purpose of applying pressure to stop bleeding. At the same time, the external dressing 1 can also wrap the wound to prevent blood from spreading, while the sealing film 3 can seal the external dressing 1 to prevent blood from seeping out.
