Description

Technical Field

[0001] The invention relates to the technical field of cranio-maxillofacial trauma hemostasis, and in particular to a first aid kit for rapid bandaging of head and facial trauma. Background Art

[0002] The modern concept of war injury treatment emphasizes the degree of social reintegration of wounded soldiers after war. The cranio-maxillofacial region is adjacent to important organs such as the eyes, mouth, spinal cord, and brain. In the emergency treatment of patients with cranio-maxillofacial trauma, early protection of the functional structures of the above-mentioned organs is of vital importance to the smooth transfer and surgical treatment of patients, as well as the recovery of vision, behavioral ability, and consciousness level.

[0003] Existing methods of hemostasis mainly include pressure bandage, nasopharyngeal balloon compression hemostasis, manual reduction hemostasis, vascular embolization and other methods. Pressure bandage requires repeated movement of the head and neck, which increases the risk of secondary cervical spine injury, is time-consuming and labor-intensive, and is difficult to operate in battlefield treatment. Nasopharyngeal balloon compression hemostasis is only suitable for intranasal bleeding, and cannot meet the needs of full facial bandage hemostasis, and an intraoral brace must be used at the same time to avoid secondary injury to patients with existing maxillary fractures. Manual reduction hemostasis requires high professionalism from emergency personnel, and it is difficult for ordinary personnel to complete it effectively. In addition to the professional requirements for medical personnel, vascular embolism, suturing and other methods also have high requirements for items and environment, and cannot be completed quickly in first aid at the war scene. Therefore, the present application provides a quick bandaging first aid kit for head and facial trauma to meet the needs. Summary of the invention

There are two adjustment belts, and the two adjustment belts are in a cross shape when installed and used.

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

[0017] In the above scheme, by setting a pressurized hemostasis mechanism and a support and limiting mechanism, not only can the on-site first aid requirements such as hemostasis, fixation, vision protection, and prevention of wound adhesion be met at the same time, but also the device can be quickly and stably fixed on the patient's head through the coordinated use of the restraint belt and the tightening belt, and the tightness of the restraint belt and the tightening belt can be quickly adjusted by adjusting the position of the ear hollow groove installed on the first limiting groove, which further makes the device more stable when installed on the heads of patients with different head shapes, and prevents the device from positional displacement when used for hemostasis protection. In addition, the device is easy to use, easy to train and master, and can be used by non-craniomaxillofacial specialists in the field medical staff and the wounded for mutual rescue, thereby improving the combat and on-site treatment efficiency of craniomaxillofacial trauma and the success rate of subsequent treatment.

[0018] By arranging a craniomaxillofacial pressure bag, an eye pressure bag, a nasal pressure bag and a mouth pressure bag in the pressurized hemostasis mechanism, the shape of the craniomaxillofacial pressure bag is adapted to the shape and structure of the human face, the shape of the nasal pressure bag is adapted to the shape of the human nose, the shape of the eye pressure bag is adapted to the shape of the human eye, and the shape of the mouth pressure bag is adapted to the shape of the human mouth. The structure performs pressurized hemostasis treatment on the eyes, nose, mouth and face of the human head separately through partitioning, so the hemostasis effect is better, and the structure conforms to ergonomics, so that the hemostasis structure can fit tightly to the user's skin when in use, thereby increasing the hemostasis effect, and the structures squeeze and act on each other when expanded and used, thereby further increasing the hemostasis effect, and the structure is simple, and the coordinated use of the structures effectively increases the use effect of the device.

[0019] By providing a third hollow groove and a pressure plate in the pressurized hemostasis mechanism, a certain space can be reserved for the craniomaxillofacial pressure bag when inflating and pressurizing, thereby increasing the air permeability of the structure to a certain extent. In addition, by utilizing the setting of the pressure plate, the inflation expansion of the craniomaxillofacial pressure bag can be unilaterally limited at the pressure plate, thereby achieving a better pressurization effect on the face of the patient opposite to the pressure plate, and a more uniform pressurized force on the face. The coordinated use of the structures further improves the hemostasis effect of the pressurized hemostasis mechanism.

[0020] By arranging a mouth frame, a first connecting frame, a nose frame and an eye frame in a supporting and limiting mechanism, the mouth frame is adapted to the contour shape of the human mouth, the nose frame, the supporting frame and the auxiliary frame are adapted to the contour shape of the human nose, the eye frame 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 side of the human face close to the ear, so that the structure composed of the mouth frame, the first connecting frame, the nose frame, the supporting frame, the auxiliary frame, the eye frame and the second connecting frame as an integrated structure can be quickly and stably attached to the patient's face, and the cranio-maxillofacial pressure bag, the eye pressure bag, the nose pressure bag and the mouth pressure bag are fixed to one side of the supporting and limiting mechanism by using the adhesive part, and the cranio-maxillofacial pressure bag, the eye pressure bag, the nose pressure bag and the mouth pressure bag are attached to the human face when the supporting and limiting mechanism is installed, and the coordinated use of the structures can quickly stop bleeding on the bleeding part of the patient's head, effectively making the supporting and limiting mechanism convenient and quick to use.

[0021] By arranging a transverse bracket, a first longitudinal bracket and a second longitudinal bracket in the support and limiting mechanism, the craniomaxillofacial pressure bag arranged on the face can be further assisted in pressurization. By using the end block and the mouth frame, the first connecting frame, the nose frame and the eye frame, grooves that are equidistantly provided on the side 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 position, so that the pressurization points of the structure can be flexibly adjusted within a certain range, so as to accurately and effectively pressurize the severe bleeding points in different parts of the face, thereby making the hemostasis effect of the device better. 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.

[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.

The distance and angle can be further adjusted, and the size of the compression force generated by the transverse bracket 16, the first longitudinal bracket 17 and the second longitudinal bracket 18 on the craniomaxillofacial pressure bag 24 at the same time can be further adjusted, and the force directly acts on the pressing piece 31 on the craniomaxillofacial pressure bag 24, and the surface pressing piece 31 evenly disperses the pressure on the craniomaxillofacial pressure bag 24, and the pressurized hemostasis makes the pressure dispersion more even, thereby making the hemostasis effect better, and the structure is simple, and the coordinated use of the structures further increases the use effect of the supporting and limiting mechanism, and the setting of the second weakened portion 21 makes the adjustment of the adjusting belt 20 more convenient, and the setting of the recessed portion 22 makes the adjusting belt 20 adapt to the facial structure of the human body, thereby making the use effect of the adjusting belt 20 better.

[0053] Among them, reserved holes 36 are opened on both sides of the mouth skeleton 9, and a reserved hole 36 is opened on the side of the eye skeleton 14 away from the second connecting frame 15. This structure forms an installation method by inserting and wrapping the forked tightening belt 2 onto the first connecting frame 10. Another installation method is to insert the tightening belt 2 into the two reserved holes 36. The above two installation methods have different pressure effects on the face. The former exerts stronger pressure on the face. The structure makes the device more flexible when used, effectively increasing the practicality of the device.

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

[0055] When in use, the bifurcated tightening belt 2 is inserted and wrapped on the first connecting frame 10, or the tightening belt 2 is inserted into the two reserved holes 36 according to the specific use conditions on site. The two installation methods have different pressure effects on the face. Then, the inclined guide at the opening of the first limiting groove 4 and the guide part 8 are used in combination to enable the end block 6 to be quickly installed in 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 into the first limiting groove 4, so that the end block 6 is pressed into the first limiting groove 4. The first weakened portion 7 is deformed, 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 weakened portion 7 rebounds to limit the end block 6, so that the end block 6 is stably placed in the first limiting groove 4. The limiting buckle 3 is in the shape of a hook. The limiting buckle 3 and the end block 6 are used in combination to stably connect the end of the tightening belt 2 with the restraining belt 1. When the restraining belt 1 is put on the user's head, the device can be stably fixed on the patient's head for use.

[0056] The craniomaxillofacial pressure bag 24, the eye pressure bag 25, the nasal pressure bag 26 and the mouth pressure bag 27 are fixed on one side of the supporting and limiting mechanism by using the adhesive part 32, and then the end block 6 and the mouth skeleton 9, the first connecting frame 10, the nasal skeleton 11 and the eye skeleton 14 are evenly spaced to form grooves that are compatible with the shape of the end block 6 on one side close to the transverse bracket 16, and the transverse bracket 16, the first longitudinal bracket 17 and the second longitudinal bracket 18 are installed at the required position, so that the pressure points of the structure can be flexibly adjusted within a certain range, so as to accurately and effectively pressurize severe bleeding points in different parts, thereby making the hemostatic effect of the device better. After the installation is completed, the cranio-maxillofacial pressure bag 24, the eye pressure bag 25, the nasal pressure bag 26 and the mouth pressure bag 27 are attached to the face of the human body, and the hemostatic layer 35 is in direct contact with the face. The hemostatic layer 35 is attached with hemostatic and anti-inflammatory drugs. Then, different amounts of air are injected into the cranio-maxillofacial pressure bag 24, the eye pressure bag 25, the nasal pressure bag 26 and the mouth pressure bag 27 according to the bleeding situation. The pressure generated by the expansion of the cranio-maxillofacial pressure bag 24, the eye pressure bag 25, the nasal pressure bag 26 and the mouth pressure bag 27 is used to pressurize the bleeding area. At the same time, the mouth skeleton 9, the first connecting frame 10, the nasal skeleton 11 and the eye skeleton 14 are used to further pressurize the cranio-maxillofacial pressure bag 24, the eye pressure bag 25, the nasal pressure bag 26 and the mouth pressure bag 27 by limiting the position.

[0057] The hemostatic effect of the device is better. At the same time, the combined use of the exudate absorption layer 33, the heat preservation layer 34 and the hemostatic layer 35 can quickly stop bleeding on the mouth, nose, eyes and face of the human head, and absorb and process the exudate in the area. At the same time, the wound can be kept warm in a low temperature environment to prevent the wound from further deteriorating. The first hollow groove 28, the second hollow groove 29 and the third hollow groove 30 are arranged so that the corresponding mouth pressure bag 27, the nose pressure bag 26 and the craniomaxillofacial pressure bag 24 can reserve a certain space when inflated and pressurized, which is convenient for the patient's breathing, and at the same time, it also increases to a certain extent. The structure has good air permeability, and the setting of the pressing sheet 31 is used to unilaterally limit the inflation of the cranio-maxillofacial pressure bag 24 at the pressing sheet 31, so that the face of the patient opposite to the pressing sheet 31 is better pressurized, and the face pressurization force is more uniform. After the installation is completed, an adjustment belt 20 is put on the first longitudinal bracket 17 and the second longitudinal bracket 18, and the second limiting groove 19 is used to limit the adjustment belt 20. The tightness of the adjustment belt 20 is adjusted by the adhesive portion 23 to further control the pressure generated by the first longitudinal bracket 17 and the second longitudinal bracket 18 on the cranio-maxillofacial pressure bag 24, and Another adjusting belt 20 is inserted and sleeved on the transverse bracket 16 and the previous adjusting belt 20. By adjusting the tightness of the adjusting belt 20, the distance and angle between the transverse bracket 16 and the first longitudinal bracket 17 and the second longitudinal bracket 18 can be further adjusted, and the magnitude of the compression force generated by the transverse bracket 16 and the first longitudinal bracket 17 and the second longitudinal bracket 18 on the craniomaxillofacial pressure bag 24 can be further adjusted. The force directly acts on the compression piece 31 on the craniomaxillofacial pressure bag 24. The surface-shaped compression piece 31 evenly disperses the pressure on the craniomaxillofacial pressure bag 24, and the pressure hemostasis makes the pressure dispersion more even. , thereby making the hemostatic effect better, and adjusting the position of the adjustment belt 20 can also flexibly adjust the maximum pressure point according to the bleeding position, thereby further increasing the hemostatic effect, and the structure of the device is simple, and the coordinated use of the structures further increases the use effect of the device, and the device partitions the eyes, nose, mouth and face of the human head to perform pressurized hemostasis treatment separately, so the hemostatic effect is better, and the structure conforms to ergonomics, so that the hemostatic structure can fit tightly to the user's skin when in use, thereby increasing the hemostatic effect, and the structures squeeze and act on each other when in use, thereby further increasing the hemostatic effect.
