DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] The present embodiment provides a quick hemostasis and pressure fixation device for trauma in emergency department, which comprises a buckle plate, a pressure plate, a driving structure, a fixing structure, a drug delivery structure, a transmission assembly and a universal structure. Figures 1-6As shown, the hemostasis and compression fixing device comprises a buckle plate 1, a pressing plate 2 arranged at the bottom of the buckle plate 1 for hemostasis of the wound surface, a driving structure 3 arranged on the buckle plate 1 for driving the pressing plate 2 to press down, and a fixing structure 4 arranged on the buckle plate 1 for fixing the device to the wound site. The hemostasis and compression fixing device further comprises a drug delivery structure 5 arranged on the pressing plate 2 and connected with the driving structure 3 for pre-soaking the hemostatic liquid into the wound surface before the pressing plate 2 contacts the wound surface for compression. The drug delivery structure 5 comprises a syringe 51 arranged on the buckle plate 1 for storing the hemostatic liquid, a medical sponge 53 fixedly arranged at the bottom of the pressing plate 2 for adapting to the wound surface, and a transmission assembly 52 arranged on the buckle plate 1 and connected with the driving structure 3 for injecting the liquid in the syringe 51 into the medical sponge 53 when the driving structure 3 moves. A universal structure 6 is arranged between the driving structure 3 and the pressing plate 2 for multi-directional angle adjustment of the pressing plate 2 to ensure that the pressing plate 2 is in close contact with the wound surface.

[0020] In use, the buckle plate 1 is first stably erected above the wound surface, and the pressing plate 2 is aligned with the wound surface. Then, the driving structure 3 is operated to drive the pressing plate 2 to move downward towards the wound surface. In this process, the driving structure 3 can synchronously drive the transmission assembly 52 of the drug delivery structure 5 to operate. The transmission assembly 52 drives the syringe 51 to release the stored hemostatic liquid. Then, the hemostatic liquid is injected into the medical sponge 53 at the bottom of the pressing plate 2 through the transmission path and is soaked. The drug delivery action is completed before the pressing plate 2 contacts the wound surface. With the operation of the driving structure 3, the pressing plate 2 gradually approaches the wound surface. At this time, the transmission assembly 52 is disconnected from the driving structure 3, and the syringe 51 stops injecting the liquid. However, the pressing plate 2 continues to move downward under the action of the driving structure 3. When the driving structure 3 drives the pressing plate 2 to contact the wound surface, the universal structure 6 between the driving structure 3 and the pressing plate 2 can flexibly adjust the contact angle of the pressing plate 2 according to the shape of the wound surface to ensure that the pressing plate 2 is in full contact with the wound surface. Then, the driving structure 3 is continuously operated to achieve compression hemostasis by the continuous pressing of the pressing plate 2. The medical sponge 53 soaked with the liquid is in close contact with the wound surface to achieve the effect of cooperative hemostasis by drug delivery and compression.

[0021] Specifically, the driving structure 3 comprises a fixed cylinder 31 fixedly installed at the top of the buckle plate 1 and located above the pressing plate 2, a lifting rod 32 longitudinally moving in the fixed cylinder 31 and connected with the universal structure 6, a screw rod 33 longitudinally penetrating through the top of the fixed cylinder 31 and rotationally connected to the fixed cylinder 31, and a knob 34 fixedly installed at the top of the screw rod 33. The end of the screw rod 33 away from the knob 34 is screw-connected with the lifting rod 32.

[0022] When the driving structure 3 is used, first confirm that the fixed cylinder 31 is fixedly installed on the top of the buckle plate 1 and above the pressing plate 2, since the screw rod 33 longitudinally penetrates the top of the fixed cylinder 31 and is rotationally connected with the fixed cylinder 31, and the end away from the knob 34 is screwed with the lifting rod 32, and the knob 34 is fixed on the top of the screw rod 33, therefore, by rotating the knob 34 to drive the screw rod 33 to rotate on the fixed cylinder 31, and by the screwing cooperation of the screw rod 33 and the lifting rod 32, the rotary motion of the knob 34 can be converted into the linear motion of the lifting rod 32 along the longitudinal direction of the fixed cylinder 31, when the lifting rod 32 is lowered, it will push the universal structure 6 to drive the pressing plate 2 to press downward to the wound surface, in this process, the rotation amplitude of the knob 34 is adjusted by observing the blood outflow of the wound surface to control the lowering amplitude of the lifting rod 32, and then the pressing force of the pressing plate 2 is adjusted, when resetting or adjustment is needed, the knob 34 is reversely rotated to drive the screw rod 33 to reversely rotate, so that the lifting rod 32 rises along the fixed cylinder 31, and the lifting rod 32 drives the pressing plate 2 to disengage from the wound surface through the universal structure 6 to complete the resetting.

[0023] Further, the fixing structure 4 includes a bandage 41 arranged on the buckle plate 1 and a magic tape 42 fixedly connected on the side of the bandage 41 away from the buckle plate 1 for adhesive fixing, one end of the bandage 41 is fixedly connected with one side of the buckle plate 1, and the other end is movably penetrated through the other side of the buckle plate 1.

[0024] When the pressing plate 2 is used to press the wound surface to stop bleeding, the movable end of the bandage 41 is pulled to make the bandage 41 wrap around the limb or trunk where the wound part of the patient is located, the tightness of the bandage 41 is adjusted according to the thickness of the limb to ensure that the position of the buckle plate 1 is stable and does not affect the blood circulation of the patient, after adjustment, the magic tape 42 on the movable end of the bandage 41 is adhered and fixed with the magic tape 42 on the adhering part of the bandage 41, so that the stable connection of the device and the wound part can be realized, on the contrary, when disassembly is needed, the magic tapes 42 adhered to each other are torn, and the movable end of the bandage 41 is pulled to make it disengage from the other side of the buckle plate 1, so that the device can be removed from the wound part.

[0025] Further, the syringe 51 includes a medicine storage cylinder 511 fixedly installed on the top of the buckle plate 1 and located on one side of the fixed cylinder 31, a piston 512 slidably connected in the medicine storage cylinder 511, a push rod 513 transversely penetrating one end of the medicine storage cylinder 511 close to the fixed cylinder 31 and slidably connected on the medicine storage cylinder 511 for connection with the transmission assembly 52, and a hose 514 sequentially penetrating and fixedly connected with the buckle plate 1 and the pressing plate 2, both ends of the hose 514 are respectively communicated with one end of the medicine storage cylinder 511 away from the push rod 513 and the inside of the medical sponge 53, and the end of the push rod 513 away from the transmission assembly 52 is fixedly connected with the piston 512.

[0026] When the driving structure 3 drives the pressing plate 2 to descend, the driving structure 3 synchronously drives the transmission assembly 52 to operate, at this time, the transmission assembly 52 drives the push rod 513 to slide along the storage cartridge 511 in the transverse direction, so that the push rod 513 pushes the piston 512 to synchronously slide in the storage cartridge 511 to the side close to the hose 514, and the hemostatic liquid in the storage cartridge 511 is pressed into the hose 514 through the extrusion of the piston 512. Then, the liquid medicine is transmitted through the hose 514 and injected into the medical sponge 53 and makes it fully infiltrate. After the driving structure 3 and the transmission assembly 52 are disconnected, the transmission assembly 52 stops driving the push rod 513, the push rod 513 and the piston 512 stop moving, the liquid in the storage cartridge 511 is no longer extruded, the syringe 51 stops injecting the liquid medicine into the medical sponge 53, and the hose 514 not only has good flexibility and can move synchronously with the descending of the pressing plate 2 to avoid the obstruction of the drug delivery path or the influence on the operation of the pressing plate 2, but also can realize the closed transmission of the liquid medicine, reduce the pollution and waste of the liquid medicine, and further ensure the safety and reliability of the first-aid process.

[0027] In order to avoid the movement interference between the transmission assembly 52 and the fixed cylinder 31, the fixed cylinder 31 is provided with a groove 311 corresponding to the position of the transmission assembly 52. The design of the groove 311 provides a dedicated installation and movement space for the gear 522 of the transmission assembly 52 and the tooth groove 523 of the lifting rod 32, effectively avoids the movement interference between the transmission assembly 52 and the fixed cylinder 31, and ensures that the tooth groove 523 and the gear 522 always remain stable meshing transmission when the lifting rod 32 ascends and descends, preventing problems such as transmission jamming and failure caused by structure collision.

[0028] Further, the transmission assembly 52 comprises a bracket 521 symmetrically and fixedly installed on the buckle plate 1 and located at the positions on both sides of the groove 311, a lead screw 524 rotatably connected to the two brackets 521, a gear 522 fixedly sleeved on the lead screw 524 and located at the position of the groove 311, a tooth groove 523 fixedly arranged on the side of the lifting rod 32 close to the groove 311, and a connecting plate 525 screwed on the lead screw 524 and fixedly connected with the end of the push rod 513 away from the piston 512. The push rod 513 is slidably connected to one of the brackets 521, and the gear 522 is meshed with the tooth groove 523.

[0029] When the lifting rod 32 of the driving structure 3 descends along the fixed cylinder 31, the tooth groove 523 on the lifting rod 32 drives the gear 522 engaged therewith to rotate, and the gear 522 drives the screw rod 524 to rotate synchronously between the two supports 521. Since the connecting plate 525 is screwed with the screw rod 524 and fixed with the push rod 513, under the double guiding actions of the supports 521 and the medicine storage cylinder 511, the rotation of the screw rod 524 is converted into the transverse movement of the connecting plate 525 along the screw rod 524, and the connecting plate 525 further pushes the push rod 513 to slide along the supports 521, so as to realize the medicine injection action of the syringe 51. Since the tooth groove 523 has a certain height, when the lifting rod 32 continues to descend, the tooth groove 523 will be disengaged from the gear 522, so that the gear 522 and the screw rod 524 stop rotating, and the connecting plate 525 and the push rod 513 also stop moving, and the transmission assembly 52 terminates transmission. After the transmission assembly 52 terminates transmission, the syringe 51 stops injecting medicine into the medical sponge 53.

[0030] In addition, in order to protect the syringe 51 and the transmission assembly 52 from external interference and pollution, the buckle plate 1 is fixedly provided with a protective box 7 for covering the outside of the syringe 51 and the transmission assembly 52. The protective box 7 is fixedly connected with the fixed cylinder 31. The protective box 7 covers the outside of the syringe 51 and the transmission assembly 52, and is fixedly connected with the fixed cylinder 31 to form a closed protection space, which can effectively block external collisions, dust, bloodstains and the like during first aid from interfering with and polluting the syringe 51 and the transmission assembly 52, and avoid drug delivery failure or transmission failure caused by component damage. The integrated design of the protective box 7 does not affect the overall operation convenience of the device, and further improves the durability and safety of the device in the first aid scene.

[0031] It is worth noting that the universal structure 6 includes a spherical groove 61 opened at the bottom of the lifting rod 32, a universal ball 62 rotationally connected in the spherical groove 61, a connecting shaft 63 fixedly connected with the universal ball 62 away from the spherical groove 61 and fixedly connected with the top of the pressing plate 2, and a locking member 64 provided on one side of the lifting rod 32 for locking the position of the universal ball 62. The locking member 64 includes a locking bolt 641 transversely penetrating one side of the lifting rod 32 and screwed with the lifting rod 32 for abutting the universal ball 62 in the lifting rod 32, and a long handle 642 fixedly connected with the locking bolt 641 away from the universal ball 62 and extending to the outer edge of the buckle plate 1.

[0032] When the lifting rod 32 of the driving structure 3 drives the pressing plate 2 to approach the wound surface, the universal ball 62 can rotate in multiple directions in the spherical groove 61, and drives the pressing plate 2 to adjust the angle of adhesion according to the shape of the wound surface through the connecting shaft 63, so as to ensure that the pressing plate 2 is fully adhered to the wound surface. After the pressing plate 2 is pressed tightly to the wound surface and the angle is adjusted to the right position, the long handle 642 is rotated to drive the locking bolt 641 to move horizontally along the lifting rod 32 until the locking bolt 641 tightly abuts the universal ball 62 in the spherical groove 61, so as to realize the position locking of the universal ball 62 and keep the angle of the pressing plate 2 stable. Conversely, when the angle needs to be adjusted or disassembled, the long handle 642 is reversely rotated to drive the locking bolt 641 to disengage from the universal ball 62, and the universal ball 62 restores the rotating freedom in the spherical groove 61, so that the angle of the pressing plate 2 can be adjusted or the pressing plate 2 can be separated from the wound surface. The long handle 642 extends to the outer edge of the buckle plate 1, which is convenient for operation and quick locking and unlocking.

[0033] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
