Description

Technical Field

[0001] The present invention relates to the technical field of craniofacial trauma hemostasis, and particularly relates to a rapid dressing first aid kit for head and facial trauma. Background Art

[0002] The modern concept of war injury treatment attaches importance to the social return degree of wounded soldiers after the war. The skull, jaw and face are adjacent to important tissue organs such as eyes, mouth, spinal cord, brain, etc. In the emergency treatment of patients with craniofacial trauma, the early protection of the functional structures of the above tissue organs is of crucial significance for the smooth transportation and surgical treatment of patients, as well as the rehabilitation of vision, behavior ability and consciousness level.

[0003] The existing hemostasis methods mainly include bandage compression dressing, nasopharyngeal balloon compression hemostasis, manual reduction hemostasis, vascular embolization, etc. Bandage compression dressing requires repeated moving of the head and neck, increasing the risk of secondary cervical spine injury, and is time-consuming and laborious, with great operation difficulty in battlefield treatment. Nasopharyngeal balloon compression hemostasis is only applicable to nasal bleeding, cannot meet the need for comprehensive facial dressing hemostasis, and requires the simultaneous use of intraoral appliances to avoid secondary injury to patients with existing maxillary fractures. Manual reduction hemostasis has high professional requirements for first aid personnel, and it is difficult for general personnel to complete effectively. Methods such as vascular embolization and suture not only have high professional requirements for treatment personnel, but also have high requirements for items and environment, and cannot be quickly completed in battlefield first aid. Therefore, the present application provides a rapid dressing first aid kit for head and facial trauma to meet the needs. Summary of the Invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by providing a pressure hemostasis mechanism and a support and limiting mechanism, it can not only meet the on-site first aid requirements such as hemostasis, fixation, vision protection, and prevention of wound adhesion at the same time, but also can quickly and stably fix the device on the patient's head through the cooperation of the restraint strap and the tightening strap. And by adjusting the position of the ear hollow groove installed on the first limiting groove, the tightness of the restraint strap and the tightening strap can be quickly adjusted, further improving the stability of the device when installed on the heads of patients with different head shapes, so that the device will not shift in position when used for hemostasis and protection. And this device is easy to use, easy to train and master, and can be used by field medical staff and wounded for mutual rescue who are not specialized in cranio-maxillofacial surgery, improving the on-site treatment efficiency and subsequent treatment success rate of cranio-maxillofacial trauma.

[0018] By providing a cranio-maxillofacial pressure sac, an eye pressure sac, a nasal pressure sac and a mouth pressure sac in the pressure hemostasis mechanism, the shape of the cranio-maxillofacial pressure sac is adapted to the shape structure of the human face, the shape of the nasal pressure sac is adapted to the shape of the human nose, the shape of the eye pressure sac is adapted to the shape of the human eye, and the shape of the mouth pressure sac is adapted to the shape of the human mouth. The structure performs separate pressure hemostasis treatment on the eyes, nose, mouth and face of the human head by zoning, and the hemostasis effect is better. And the structure conforms to ergonomics, so that the hemostasis structure can closely fit the user's skin when in use, thereby increasing the hemostasis effect. And when the structures expand and use, they squeeze and act on each other, thereby further increasing the hemostasis effect. And the structure is simple, and the cooperation between the structures effectively increases the use effect of the device.

[0019] By providing a third hollow groove and a pressing piece inside the pressure hemostasis mechanism, a certain space can be reserved when the craniofacial pressure sac is inflated and pressurized, which increases the air permeability of the structure to a certain extent. And by using the pressing piece, the inflation and expansion of the craniofacial pressure sac at the pressing piece is unidirectionally limited, so that the pressing effect on the patient's face on the opposite side of the pressing piece is better, and the pressing force on the face is more uniform. The coordinated use of the structures further improves the hemostasis effect of the pressure hemostasis mechanism.

[0020] By providing a mouth skeleton, a first connecting frame, a nose skeleton and an eye skeleton inside the support and limit mechanism, the mouth skeleton is adapted to the contour shape of the human mouth, the nose skeleton, the support frame and the auxiliary frame are adapted to the contour shape of the human nose, the eye skeleton and the second connecting frame are adapted to the contour shape of the human eye, and the first connecting frame is adapted to the shape of the human face near the ear side, the mouth skeleton, the first connecting frame, the nose skeleton, the support frame, the auxiliary frame, the eye skeleton and the second connecting frame can be quickly and stably attached to the patient's face as an integrated structure. And by using the sticking part, the craniofacial pressure sac, the eye pressure sac, the nose pressure sac and the mouth pressure sac are fixed on one side of the support and limit mechanism, and when the support and limit mechanism is installed, the craniofacial pressure sac, the eye pressure sac, the nose pressure sac and the mouth pressure sac are attached to the patient's face. The coordinated use of the structures quickly stops the bleeding at the bleeding part of the patient's head, effectively making the support and limit mechanism convenient and fast to use.

[0021] By providing a transverse bracket, a first longitudinal bracket and a second longitudinal bracket inside the support and limit mechanism, further auxiliary pressurization can be performed on the craniofacial pressure sac arranged on the face. By using the end block and the slots which are equally spaced on one side of the mouth skeleton, the first connecting frame, the nose skeleton and the eye skeleton close to the transverse bracket and are adapted to the shape of the end block, the transverse bracket, the first longitudinal bracket and the second longitudinal bracket are installed at the required positions, so that the pressurization points of the structure can be flexibly adjusted within a certain range, thereby accurately and effectively pressurizing the severe bleeding points at different parts of the face, and further improving the hemostasis effect of the device. The coordinated use of the structures further increases the use effect of the support and limit mechanism, and the setting of the second weakening part makes the adjustment of the adjustment belt more convenient.

[0022] By providing an adjustment belt in the support and limiting mechanism, an adjustment belt can be used to cover the first longitudinal bracket and the second longitudinal bracket, and the tightness of the adjustment belt can be used to further control the pressure generated by the first longitudinal bracket and the second longitudinal bracket on the craniomaxillofacial pressure bag. Another adjustment belt is inserted and sleeved on the transverse bracket and the previous adjustment belt. Adjusting the tightness of this adjustment belt can further adjust the distance and angle between the transverse bracket and the first longitudinal bracket and the second longitudinal bracket, and then further adjust the size of the compression force generated by the transverse bracket and the first longitudinal bracket and the second longitudinal bracket on the craniomaxillofacial pressure bag at the same time. The coordinated use of the structures further increases the use effect of the support and limiting mechanism, and the provision of the second weakened portion makes the adjustment of the adjustment belt more convenient. At the same time, the provision of the recess makes the adjustment belt adapt to the human facial structure, thereby making the use effect of the adjustment belt better.

[0023] In summary, the device uses the pressurized hemostasis mechanism and the support and limit mechanism and the various components therein, which can not only enable the medical staff and soldiers on the battlefield to quickly fix the device to the bleeding part of the head, but also use the frame and airbag inside the device to make the device more flexible and have a better hemostasis effect, effectively meeting the hemostasis needs of patients with a wide range and deep injury, and the device uses zoned pressurized hemostasis to simultaneously meet the on-site first aid requirements such as hemostasis, fixation, vision protection, and prevention of wound adhesion. It is easy to use, easy to train and master, and can be used by non-craniomaxillofacial specialists in the battlefield and for mutual rescue of the wounded, improving the combat and on-site treatment efficiency of craniomaxillofacial trauma and the success rate of subsequent treatment.

[0046] As Figures 1 to 5As shown in the figure, an embodiment of the present invention provides a first-aid kit for rapid bandaging of head and facial trauma, which includes a restraint strap 1. Both ends of the restraint strap 1 are fixedly connected with tightening straps 2. The ends of the tightening straps 2 are fixedly connected with limit buckles 3. The side of the restraint strap 1 close to the tightening strap 2 and the tightening strap 2 are both equidistantly provided with first limit grooves 4. An ear hollowing groove 5 is provided on the restraint strap 1. The end of the tightening strap 2 is provided with a first connecting frame 10; a pressure hemostasis mechanism, which is used to quickly stop bleeding at the bleeding site of the patient, and the pressure hemostasis mechanism is connected to the first connecting frame 10; a support and limit mechanism, which is used to limit and further pressurize the pressure hemostasis mechanism, and the support and limit mechanism is connected to the first connecting frame 10. The integrated hemostatic bandage formed by the cooperation of each component in the pressure hemostasis mechanism and the support and limit mechanism of this device can simultaneously meet the on-site first-aid requirements such as hemostasis, fixation, vision protection, and prevention of wound adhesion. For specific details, see the following description. And through the combined use of the restraint strap 1 and the tightening strap 2, the device can be quickly and stably fixed on the patient's head. And by adjusting the position of the ear hollowing groove 5 installed on the first limit groove 4, the tightness of the restraint strap 1 and the tightening strap 2 can be quickly adjusted, further improving the stability of the device when installed on the heads of patients with different head shapes, so that the device will not shift in position during hemostatic protection use. And this device is easy to use, easy to train and master, and can be used by non-craniomaxillofacial specialists in battlefield medical care and for mutual rescue among the wounded, improving the efficiency of battlefield and on-site treatment of craniomaxillofacial trauma and the success rate of subsequent treatment.

[0047] Among them, the end of the limit buckle 3 is fixedly connected with an end block 6 whose shape is adapted to the first limit groove 4. Both sides of the end block 6 are provided with first weakening parts 7. The side of the end block 6 away from the limit buckle 3 is provided with a guiding part 8. The opening of the first limit groove 4 is an inclined structure adapted to the shape of the end of the limit buckle 3. The end block 6 is provided with three convex parts. One first weakening part 7 is correspondingly provided at each of two of the convex parts, and a guiding part 8 is correspondingly provided at the other convex part. A buffer cavity is provided in the end block 6. This structure uses the cooperation of the inclined plane at the opening of the first limit groove 4 and the guiding part 8, so that the end block 6 can be quickly installed into the first limit groove 4. At the same time, when installing the end block 6, a force that squeezes the end block 6 into the first limit groove 4 is applied to the end block 6, causing the first weakening part 7 on the end block 6 to deform, and then enabling the end block 6 to be more quickly installed into the first limit groove 4. When the end block 6 completely enters the first limit groove 4, the first weakening part 7 rebounds to limit the end block 6, so that the end block 6 is stably placed in the first limit groove 4. And the limit buckle 3 is in a hook shape. The combined use of the limit buckle 3 and the end block 6 further stably connects the end of the tightening strap 2 to the restraint strap 1, and then enables the device to be stably fixed on the patient's head for use, thus making the installation of the device more convenient. The combined use of the structures effectively increases the practicability of the device.

[0048] As Figure 1, Figure 2 and Figure 13 As shown in Figure 2 and Figure 13 , the pressure hemostasis mechanism includes a craniofacial pressure bladder 24 mounted on the first connecting frame 10. A nasal pressure bladder 26 is provided between the two craniofacial pressure bladders 24. A mouth pressure bladder 27 is provided at the bottom of the nasal pressure bladder 26. An eye pressure bladder 25 is provided at the top of the craniofacial pressure bladder 24. The shape of the craniofacial pressure bladder 24 is adapted to the shape structure of the human face. The shape of the nasal pressure bladder 26 is adapted to the shape of the human nose. The shape of the eye pressure bladder 25 is adapted to the shape of the human eye. The shape of the mouth pressure bladder 27 is adapted to the shape of the human mouth. The structure performs separate pressure hemostasis treatment on the eyes, nose, mouth and face of the human head through zoning, with better hemostasis effect. And the structure conforms to ergonomics, enabling the hemostasis structure to closely fit the user's skin during use, thereby increasing the hemostasis effect. And when the structures are used, they squeeze and act on each other, further increasing the hemostasis effect. Moreover, the structure is simple, and the combined use of the structures effectively improves the use effect of the device.

[0049] Among them, a liquid seepage adsorption layer 33 is provided on one side of the craniofacial pressure bladder 24, the eye pressure bladder 25, the nasal pressure bladder 26 and the mouth pressure bladder 27 close to the restraint band 1. A heat preservation layer 34 is provided on one side of the liquid seepage adsorption layer 33 close to the restraint band 1. A hemostasis layer 35 is provided on one side of the heat preservation layer 34 close to the restraint band 1. The shapes of the liquid seepage adsorption layer 33, the heat preservation layer 34 and the hemostasis layer 35 are completely consistent with the shape structures of their corresponding pressure bladders, and the slotting positions are the same. By using the combined use of the liquid seepage adsorption layer 33, the heat preservation layer 34 and the hemostasis layer 35, rapid hemostasis can be performed on the mouth, nose, eyes and face of the human head, and the seepage of the area can be absorbed and treated. At the same time, in a relatively low-temperature environment, the wound can be kept warm to prevent the wound from deteriorating further. The combined use of the structures further makes the use effect of the pressure hemostasis mechanism better, and the structure is simple and convenient to use.

[0050] As Figure 2 and Figure 12As shown, two second hollow slots 29 are symmetrically opened at the bottom of the nasal part pressing bladder 26, a first hollow slot 28 is opened in the middle of the mouth part pressing bladder 27, a third hollow slot 30 is opened on the craniofacial pressing bladder 24, a pressing piece 31 is arranged in the middle of the craniofacial pressing bladder 24, air charging and discharging holes are arranged on the craniofacial pressing bladder 24, the eye part pressing bladder 25, the nasal part pressing bladder 26 and the mouth part pressing bladder 27. The position of the second hollow slot 29 corresponds to the position of the human nostrils, and the shape and size of the second hollow slot 29 are adapted to the shape and size of the human nostrils. The position of the first hollow slot 28 corresponds to the position of the human lip part, and the shape and size of the first hollow slot 28 are adapted to the shape of the human lip part. By using the settings of the first hollow slot 28, the second hollow slot 29 and the third hollow slot 30, the corresponding mouth part pressing bladder 27, nasal part pressing bladder 26 and craniofacial pressing bladder 24 can reserve a certain space when inflated and pressurized, which is convenient for the patient's breathing. At the same time, the air permeability of the structure is increased to a certain extent. And by using the setting of the pressing piece 31, the inflation and expansion of the craniofacial pressing bladder 24 at the pressing piece 31 is unidirectionally limited, so that the pressing effect on the patient's face on the opposite side of the pressing piece 31 is better, and the pressing force on the face is more uniform. The cooperation between the structures further makes the hemostasis effect of the hemostasis mechanism better, and the structure is simple and has good practicability.

[0051] As Figures 2 to 9As shown, the support and limit mechanism includes a mouth skeleton 9 installed on the first connecting frame 10.

The mouth skeleton 9 is adapted to the contour shape of the human mouth. The nose skeleton 11, the support frame 12, and the auxiliary frames 13 are adapted to the contour shape of the human nose. The eye skeletons 14 and the second connecting frame 15 are adapted to the contour shape of the human eyes. The first connecting frame 10 is adapted to the shape of the side of the human face near the ear. Four corners of the craniofacial compression bladder 24 are provided with sticking parts 32. The sides of the eye compression bladder 25, the nose compression bladder 26, and the mouth compression bladder 27 close to the restraint band 1 are provided with sticking parts 32. Magic tapes are provided at the positions corresponding to the sticking parts 32 on the mouth skeleton 9, the first connecting frame 10, the nose skeleton 11, and the eye skeletons 14. Through the above integrally formed structure, the support and limit mechanism is quickly and stably attached to the patient's face, and the craniofacial compression bladder 24, the eye compression bladder 25, the nose compression bladder 26, and the mouth compression bladder 27 are fixed to one side of the support and limit mechanism by using the sticking parts 32. When installing the support and limit mechanism, the craniofacial compression bladder 24, the eye compression bladder 25, the nose compression bladder 26, and the mouth compression bladder 27 are attached to the human face, and the hemostatic layer 35 is in direct contact with the face. Hemostatic and anti-inflammatory drugs are attached to the hemostatic layer 35. The cooperation between the structures is used to quickly stop bleeding at the bleeding part of the patient's head. The design of the support frame 12 and the auxiliary frames 13 can provide auxiliary support for the patient's nose, preventing secondary injury caused by nasal fracture. The structure is convenient and fast to use, has a good hemostatic effect, and effectively increases the practicability of the device.

[0052] As Figures 9 to 11As shown, a transverse bracket 16 is installed between the first connecting bracket 10 and the nasal bone framework 11, a first longitudinal bracket 17 is installed between the eye bone framework 14 and the mouth bone framework 9, and a second longitudinal bracket 18 is installed on the side of the first longitudinal bracket 17 close to the nasal bone framework 11. End blocks 6 are fixedly connected to both ends of the transverse bracket 16, the first longitudinal bracket 17, and the second longitudinal bracket 18. Second limiting grooves 19 are equidistantly arranged on the second longitudinal bracket 18. Grooves adapted to the shape of the end blocks 6 are equidistantly arranged on the side of the mouth bone framework 9, the first connecting bracket 10, the nasal bone framework 11, and the eye bone framework 14 close to the transverse bracket 16. The transverse bracket 16, the first longitudinal bracket 17, and the second longitudinal bracket 18 are all made of plastic material. An adjusting strap 20 is installed on the transverse bracket 16. Second weakening parts 21 are arranged on both sides of the adjusting strap 20. A concave part 22 is arranged in the middle of the adjusting strap 20. A sticking part 23 is arranged at the end of the adjusting strap 20. There are two adjusting straps 20. When installed and used, the two adjusting straps 20 are in a cross shape. According to the specific on-site use situation, by using the end blocks 6 and the grooves adapted to the shape of the end blocks 6 equidistantly arranged on the side of the mouth bone framework 9, the first connecting bracket 10, the nasal bone framework 11, and the eye bone framework 14 close to the transverse bracket 16, the transverse bracket 16, the first longitudinal bracket 17, and the second longitudinal bracket 18 are installed at the required positions, so that the pressurizing points of the structure can be flexibly adjusted within a certain range, thereby accurately and effectively pressurizing severe bleeding points in different parts, and further making the hemostatic effect of the device better. And after installation, one adjusting strap 20 is sleeved on the first longitudinal bracket 17 and the second longitudinal bracket 18, and the adjusting strap 20 is limited by the second limiting groove 19. Adjusting the tightness of the adjusting strap 20 by using the sticking part 23 can further control the pressure generated by the first longitudinal bracket 17 and the second longitudinal bracket 18 on the craniofacial pressure sac 24. And the other adjusting strap 20 is inserted and sleeved on the transverse bracket 16 and the previous adjusting strap 20. Adjusting the tightness of this adjusting strap 20 can further adjust the distance and angle between the transverse bracket 16 and the first longitudinal bracket 17 and the second longitudinal bracket 18, and further can further adjust the magnitude of the pressing force generated by the transverse bracket 16 and the first longitudinal bracket 17 and the second longitudinal bracket 18 on the craniofacial pressure sac 24 at the same time. And the force directly acts on the pressing piece 31 on the craniofacial pressure sac 24. The planar pressing piece 31 evenly disperses the pressure on the craniofacial pressure sac 24, and the pressure is more evenly dispersed during pressurized hemostasis, thereby making the hemostatic effect better. And the structure is simple. The combined use of the structures further increases the use effect of the support and limiting mechanism. And the setting of the second weakening part 21 makes the adjustment of the adjusting strap 20 more convenient. At the same time, the setting of the concave part 22 makes the adjusting strap 20 adapt to the human face structure, thereby making the use effect of the adjusting strap 20 better.

[0053] Wherein, reserved holes 36 are formed on both sides of the mouth framework 9, and a reserved hole 36 is formed on the side of the eye framework 14 away from the second connecting frame 15. In this structure, an installation method is formed by inserting and wrapping the bifurcated tightening belt 2 around the first connecting frame 10. Another installation method is to insert the tightening belt 2 into the two reserved holes 36. The pressure effects on the face formed by the above two installation methods are different. The former has a stronger pressure on the face, and the structure makes the device more flexible in use, effectively increasing the practicality of the device.

[0054] The working process of the technical solution of the present invention is as follows:

[0055] During use, according to the specific on-site use situation, the bifurcated tightening belt 2 is inserted and wrapped around the first connecting frame 10, or the tightening belt 2 is inserted into the two reserved holes 36. The pressure effects on the face formed by the two installation methods are different. Then, by using the cooperation of the inclined surface at the opening of the first limiting groove 4 and the guiding portion 8, the end block 6 can be quickly installed into the first limiting groove 4. At the same time, when installing the end block 6, a force is applied to the end block 6 to squeeze it into the first limiting groove 4, causing deformation at the first weakening portion 7 of the end block 6, so that the end block 6 can be installed into the first limiting groove 4 more quickly. When the end block 6 completely enters the first limiting groove 4, the first weakening portion 7 rebounds to limit the end block 6, making the end block 6 stably placed in the first limiting groove 4. The limiting buckle 3 is in a hook shape, and the cooperation of the limiting buckle 3 and the end block 6 makes the end of the tightening belt 2 stably connected to the binding belt 1. When the binding belt 1 is put on the user's head, the device can be stably fixed on the patient's head for use.

[0056] Fix the craniofacial compression bladder 24, eye compression bladder 25, nasal compression bladder 26 and oral compression bladder 27 on one side of the support and limit mechanism by using the pasting position 32. Then, on the side of the end block 6, the oral skeleton 9, the first connecting frame 10, the nasal skeleton 11 and the eye skeleton 14 near the transverse bracket 16 are equally spaced with grooves adapted to the shape of the end block 6. Install the transverse bracket 16, the first longitudinal bracket 17 and the second longitudinal bracket 18 at the required positions, so that the pressurizing points of the structure can be flexibly adjusted within a certain range, thereby accurately and effectively pressurizing the severe bleeding points in different parts, and then making the hemostatic effect of the device better. After the installation is completed, attach the craniofacial compression bladder 24, eye compression bladder 25, nasal compression bladder 26 and oral compression bladder 27 to the human face, and make the hemostatic layer 35 directly contact the face. The hemostatic layer 35 is attached with drugs such as hemostasis and anti-inflammatory. Then, inject different amounts of air into the craniofacial compression bladder 24, eye compression bladder 25, nasal compression bladder 26 and oral compression bladder 27 according to the bleeding situation. Use the pressure generated by the inflation of the craniofacial compression bladder 24, eye compression bladder 25, nasal compression bladder 26 and oral compression bladder 27 to pressurize the bleeding site. At the same time, use the limiting effect of the oral skeleton 9, the first connecting frame 10, the nasal skeleton 11 and the eye skeleton 14 on the craniofacial compression bladder 24, eye compression bladder 25, nasal compression bladder 26 and oral compression bladder 27 to further pressurize.

[0057] To make the hemostatic effect of the device better, the combined use of the exudate absorption layer 33, the heat preservation layer 34 and the hemostatic layer 35 can quickly stop bleeding from the mouth, nose, eyes and face of the human head, absorb and process the exudate in the area, and keep the wound warm in a low-temperature environment to prevent the wound from deteriorating further. The first hollow groove 28, the second hollow groove 29 and the third hollow groove 30 are provided so that the corresponding mouth pressure bladder 27, nose pressure bladder 26 and craniofacial pressure bladder 24 can reserve a certain space when inflated and pressurized, facilitating the patient's breathing, and to a certain extent increasing the air permeability of the structure. And by the setting of the pressing piece 31, the inflation and expansion of the craniofacial pressure bladder 24 at the pressing piece 31 is unidirectionally limited, so that the pressing effect on the patient's face opposite to the pressing piece 31 is better, and the face pressing force is more uniform. After installation, an adjusting belt 20 is sleeved on the first longitudinal bracket 17 and the second longitudinal bracket 18, and the second limiting groove 19 is used to limit the adjusting belt 20. Adjusting the tightness of the adjusting belt 20 by the adhesive part 23 can further control the pressure generated by the first longitudinal bracket 17 and the second longitudinal bracket 18 on the craniofacial pressure bladder 24. And another adjusting belt 20 is inserted and sleeved on the transverse bracket 16 and the previous adjusting belt 20. Adjusting the tightness of this adjusting belt 20 can further adjust the distance and angle between the transverse bracket 16, the first longitudinal bracket 17 and the second longitudinal bracket 18, and further adjust the magnitude of the pressing force generated by the transverse bracket 16, the first longitudinal bracket 17 and the second longitudinal bracket 18 on the craniofacial pressure bladder 24 at the same time. And the force directly acts on the pressing piece 31 on the craniofacial pressure bladder 24. The planar pressing piece 31 evenly disperses the pressure on the craniofacial pressure bladder 24, making the pressure dispersion more uniform during pressure hemostasis, and thus making the hemostatic effect better. Adjusting the position of the adjusting belt 20 can also flexibly adjust the maximum pressing point according to the bleeding position, further increasing the hemostatic effect. The structure of the device is simple, and the combined use of the structures further increases the use effect of the device. And the device separately presses and stops bleeding from the eyes, nose, mouth and face of the human head in different areas, with a better hemostatic effect. And the structure conforms to ergonomics, so that the hemostatic structure can closely fit the user's skin during use, thus increasing the hemostatic effect. And when the structures are used, they squeeze and act on each other, further increasing the hemostatic effect.
