Description

Technical Field

[0001] The invention belongs to the technical field of radial artery hemostat, in particular to a multifunctional radial artery hemostat. Background Art

[0002] The radial artery compression hemostat is a medical device used to control bleeding, usually used in first aid, surgery, and other related medical scenarios. It can reduce bleeding by compressing the radial artery, prevent excessive blood loss, and help medical staff perform surgery and treatment when necessary. The radial artery compression hemostat is mainly composed of the following parts: compression belt: located in the upper arm, used to apply pressure to the radial artery; handle: used to adjust and control the pressure of the compression belt; pressure gauge: used to display the pressure of the compression belt. The working principle of the radial artery compression hemostat is to form a pressure blockage at the radial artery by applying pressure, so as to reduce blood flow and achieve the purpose of hemostasis. When the radial artery is compressed, blood can only circulate in the area between the upper arm and the elbow, and cannot flow to the hand, thereby reducing the amount of bleeding.

[0003] After searching, the Chinese patent with the authorization announcement number CN103654907B discloses a multifunctional radial artery hemostat, which can not only stop bleeding at the radial artery bleeding point of the patient, but also detect the patient's blood pressure and pulse through the device.

[0018] 2. When the present invention is used, when the bottom of the hemostatic plate contacts the wound site of the radial artery of the patient, as the hemostatic plate applies pressure to the wound site of the radial artery of the patient, the airbag is compressed and deflated by the reaction force of the wound site of the radial artery of the patient, and the air inside the airbag is pressed into the interior of the two air distribution ducts through the main air pipe and the main airway, and then discharged into the interior of the two cylinders through the two air distribution pipes, so that the pressure inside the two cylinders increases, and the two piston columns are pushed upward, and the splint drives the brake plate to rotate together with the rotation of the torsion sleeve, so that it is blocked by the upward piston column and stops rotating, so as to prevent the hemostatic plate from exerting too much pressure on the patient's wound.

[0019] 3. After hemostasis is completed, the medical staff presses the two pressing blocks, and pushes the two clamping plates and the two friction shoes toward the outer wall of the friction ring through the connection of the push rod until the two friction shoes collide with the outer wall of the friction ring, and then rotates the torsion sleeve in the opposite direction. Since an inclined surface is provided on the top of the piston column, the reverse rotation of the clamping plates drives the reverse rotation of the brake pads, and the piston column is pushed downward under the action of the wedge force between the bottom of the brake pad and the inclined surface, thereby not affecting the reverse rotation of the torsion sleeve, and making it convenient to remove the present invention after hemostasis.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 11 The technical solution provided by the present invention specifically includes the following embodiments:

[0034] Embodiment 1

[0035] The multifunctional radial artery hemostat has a hemostatic sliding hole 101 formed through the top of the base 100, and a hemostatic member is slidably provided inside the hemostatic sliding hole 101. Both ends of the base 100 have mounting grooves 103, and a strap 200 is fixedly installed between the two mounting grooves 103, and the strap 200 is made of a flexible non-woven fabric.

[0036] The blood pressure stop device includes a compression inner wire tube 301 slidably installed inside the hemostatic sliding hole 101, a plurality of buffer springs 303 distributed at equal angles are fixedly installed at the bottom of the compression inner wire tube 301, a hemostatic plate 304 is fixedly installed at the bottom of the plurality of buffer springs 303, an adjusting screw 307 is spirally screwed on the inner wall of the buffer spring 303, a torsion sleeve 309 is provided for rotation on the outer periphery of the adjusting screw 307, an adapter sleeve 308 is fixedly installed on the top wall of the torsion sleeve 309, the top of the adjusting screw 307 is rotationally connected to the adapter sleeve 308 through an axle pin, two pressing grooves 3010 are symmetrically provided on the upper part of the outer wall of the torsion sleeve 309, a pressing block 3011 is slidably installed inside the pressing groove 3010, and two front and rear pressing blocks 3011 are fixedly installed on the side close to each other. The two push rods 3012 are distributed, and a clamping plate 3013 is fixedly installed at one end of the two push rods 3012 away from the pressing block 3011. A friction shoe 3014 is fixedly installed on the side of the clamping plate 3013 away from the push rods 3012. A reset spring 3015 is provided on the outer sleeve of the push rods 3012. The reset spring 3015 is fixedly installed between the inner wall of the torsion sleeve 309 and the clamping plate 3013. A friction ring 3016 is fixedly installed on the upper part of the outer wall of the adjusting screw 307. The inner wall of the hemostatic sliding hole 101 is provided with a plurality of key grooves 102 distributed at equal angles. The outer wall of the compression inner wire tube 301 is fixedly installed with a plurality of key blocks 302 distributed at equal angles. The specifications of the key blocks 302 are adapted to the specifications of the key grooves 102, and the outer wall of the key blocks 302 is slidably connected with the inner wall of the key grooves 102.

[0037] Specifically, in this embodiment, the bandage 200 and the base 100 are put on the radial artery blood vessel part of the patient's wrist where bleeding is required, and the hemostatic plate 304 is ensured to be located outside the radial artery of the patient. The medical staff presses the two pressing blocks 3011, and pushes the two splints 3013 and the two friction tiles 3014 toward the outer wall of the friction ring 3016 through the connection of the push rod 3012 until the two friction tiles 3014 collide with the outer wall of the friction ring 3016, and continue to keep the two pressing blocks 3011 pressed. The pressing force of the pressing block 3011 rotates the torsion sleeve 309 at the same time. The rotation of the torsion sleeve 309 drives the clamping plate 3013 and the friction shoe 3014 to rotate together through the top rod 3012. Since the two friction shoes 3014 and the friction ring 3016 are in conflict with each other, the rotation of the two friction shoes 3014 drives the friction ring 3016 to rotate together with the adjusting screw 307. The spiral thrust between the rotation of the adjusting screw 307 and the compression of the inner wire tube 301 compresses the inner wire tube 301 along the hemostatic sliding hole 10 1, due to the sliding torque limiting effect between the multiple key blocks 302 fixed on the outer wall of the compression inner wire tube 301 and the multiple key grooves 102, it is ensured that the compression inner wire tube 301 will not rotate during the process of being pushed downward. Therefore, the compression inner wire tube 301 moves downward through the multiple buffer springs 303 to drive the hemostatic plate 304 to move downward together until the bottom of the hemostatic plate 304 tightly presses the patient's radial artery, thereby achieving the purpose of hemostasis; after the medical staff stops pressing the two pressing blocks 3011, the reset spring 3015 pushes the friction shoe 3014 to reset under the action of the rebound force, and releases the conflict with the friction ring 3016, that is, after the pressing of the two pressing blocks 3011 is stopped, if the torsion sleeve 309 rotates again, it will not drive the adjusting screw 307 to rotate. Therefore, the compression inner wire tube 301 will not move upward or downward, avoiding the rotation of the torsion sleeve 309 to cause damage to the patient's radial artery wound again, thereby improving the safety and protection of hemostasis.

[0038] Furthermore, a sheath 305 is fixedly installed on the top of the hemostatic plate 304, and the sheath 305 is located outside the plurality of buffer springs 303, and the inner wall of the sheath 305 is provided with a plurality of slide grooves 306 distributed at equal angles, and the inner wall of the slide groove 306 is slidably connected to the outer wall of the key block 302;

[0039] By setting the key block 302 and the slide groove 306 in sliding connection, it is ensured that the hemostatic plate 304 and the compression inner wire tube 301 can only be extended and retracted up and down, preventing the hemostatic plate 304 and the compression inner wire tube 301 from lateral movement, so as to avoid continued bleeding of the wound due to unstable hemostasis.

[0040] Embodiment 2

[0041] Two air distribution ducts 401 are provided at the top of the compression inner wire tube 301, and the two air distribution ducts 401 are symmetrically distributed about the center of the compression inner wire tube 301. A main air duct 402 is provided at the bottom of the compression inner wire tube 301, and the interior of the main air duct 402 is connected with the interiors of the two air distribution ducts 401. A main air pipe 403 is fixedly installed at the bottom of the compression inner wire tube 301, and the main air pipe 403 is located at the periphery of the opening of the main air duct 402. A safety airbag 404 is fixedly installed at the bottom of the buffer spring 303, and the output end of the safety airbag 404 is fixedly connected to the bottom input end of the main air pipe 403;

[0042] Two rectangular grooves 405 are provided on the top of the compression inner wire tube 301, and the two rectangular grooves 405 are symmetrically distributed about the center of the compression inner wire tube 301, and the two rectangular grooves 405 are located at the periphery of the two air distribution ducts 401, and L-shaped slides 406 are slidably installed inside the rectangular grooves 405, and the inner wall of the twist sleeve 309 is provided with a guide circular groove 3001, and the end of the L-shaped slide 406 is slidably installed inside the guide circular groove 3001, and the cross section of the L-shaped slide 406 is fixedly installed. There is a cylinder 407, a piston column 408 is slidably installed inside the cylinder 407, an inclined surface 409 is provided on the top of the piston column 408, a tension spring 4010 is fixedly installed between the bottom of the piston column 408 and the bottom wall of the cylinder 407, a brake pad 4013 is fixedly installed on the bottom of the clamping plate 3013, a round hole 4014 is provided downwardly through the top of the brake pad 4013 away from the clamping plate 3013, and the specification of the round hole 4014 is adapted to the specification of the piston column 408;

[0043] The bottom of the piston column 408 is provided with an air hole 4011, which is connected to the inside of the piston column 408. An air distribution pipe 4012 is fixedly installed between the top of the air distribution channel 401 and the bottom of the air hole 4011. A clearance groove 4006 is penetrated through the side of the L-shaped slide 406, and the air distribution pipe 4012 is located inside the clearance groove 4006.

[0044] Specifically, in this embodiment, when the bottom of the hemostatic plate 304 contacts the wound site of the radial artery of the patient, as the hemostatic plate 304 applies pressure to the wound site of the radial artery of the patient, the airbag 404 is compressed and deflated by the reaction force of the wound site of the radial artery of the patient, and the air inside the airbag 404 is pressed into the interior of the two air distribution channels 401 through the main air pipe 403 and the main air channel 402, and then discharged into the interior of the two cylinders 407 through the two air distribution pipes 4012, so that the pressure inside the two cylinders 407 increases, and the two piston rods 408 are pushed upward, and the clamping plate 3013 drives the brake plate 4013 to rotate together with the rotation of the torsion sleeve 309, so that it is blocked by the upward piston column 408 and stops rotating, so as to prevent the hemostatic plate 304 from exerting too much pressure on the patient's wound.

[0045] It should be noted that after hemostasis is completed, the medical staff presses the two pressing blocks 3011, and pushes the two clamping plates 3013 and the two friction shoes 3014 toward the outer wall of the friction ring 3016 through the connecting action of the push rod 3012, until the two friction shoes 3014 collide with the outer wall of the friction ring 3016, and then rotates the torque sleeve 309 in the opposite direction. Since the top of the piston column 408 is provided with a slope 409, the reverse rotation of the clamping plate 3013 drives the brake plate 4013 to reverse, and the piston column 408 is pushed downward under the action of the wedge force between the bottom of the brake plate 4013 and the slope 409, so that the reverse rotation of the torque sleeve 309 will not be affected, and the present invention can be conveniently removed after hemostasis.

[0046] Embodiment 3

[0047] A damping spring 501 is fixedly installed on the bottom wall of the compression inner wire tube 301, a bottom damping gasket 502 is fixedly installed on the top of the damping spring 501, a top damping gasket 503 is fixedly installed on the bottom of the adjustment screw 307, and the bottom of the top damping gasket 503 abuts against the top of the bottom damping gasket 502;

[0048] Specifically, the elastic force of the damping spring 501 is used to ensure that the top of the bottom damping gasket 502 and the bottom of the top damping gasket 503 are always in contact with each other, so that the friction between the bottom damping gasket 502 and the top damping gasket 503 prevents the adjusting screw 307 and the compression inner wire tube 301 from rotating.

[0049] Embodiment 4

[0050] Two vertically distributed adapter rings 601 are fixedly installed on the lower inner wall of the twist sleeve 309, and an adapter circular sleeve 602 is fixedly installed on the top of the base 100. The adapter circular sleeve 602 is located outside the opening of the hemostatic sliding hole 101. Two vertically distributed annular grooves 603 are provided on the outer wall of the adapter circular sleeve 602. The adapter ring 601 is rotatably installed inside the annular groove 603.

[0051] Specifically, in this embodiment, the torsion sleeve 309 is stably and smoothly rotatably installed on the top of the base 100 by providing the annular groove 603 and the rotatable connection with the adapter ring 601 .

[0052] When the present invention is in operation, the bandage 200 and the base 100 are placed on the radial artery blood vessel portion of the patient's wrist where bleeding is to be stopped, and the hemostatic plate 304 is ensured to be located outside the radial artery of the patient. The medical staff presses the two pressing blocks 3011, and pushes the two splints 3013 and the two friction tiles 3014 toward the outer wall of the friction ring 3016 through the connecting action of the push rod 3012, until the two friction tiles 3014 collide with the outer wall of the friction ring 3016, and continue to keep the two pressing blocks 3011 pressed against the outer wall of the friction ring 3016. The pressing force of the pressing block 3011 rotates the torsion sleeve 309 at the same time. The rotation of the torsion sleeve 309 drives the clamping plate 3013 and the friction shoe 3014 to rotate together through the top rod 3012. Since the two friction shoes 3014 and the friction ring 3016 are in conflict with each other, the rotation of the two friction shoes 3014 drives the friction ring 3016 to rotate together with the adjusting screw 307. The spiral thrust between the rotation of the adjusting screw 307 and the compression of the inner wire tube 301 compresses the inner wire tube 301 along the hemostatic sliding hole 101. The inner wall is pushed downward. Due to the sliding torque limiting effect between the multiple key blocks 302 fixed on the outer wall of the compression inner wire tube 301 and the multiple key grooves 102, it is ensured that the compression inner wire tube 301 will not rotate during the process of being pushed downward. Therefore, the compression inner wire tube 301 moves downward through the multiple buffer springs 303 to drive the hemostatic plate 304 to move downward together until the bottom of the hemostatic plate 304 tightly presses the patient's radial artery, thereby achieving the purpose of hemostasis. Subsequently, after the medical staff stops pressing the two pressing blocks 3011, the reset spring 3015 pushes the friction shoe 3014 to reset under the action of the rebound force, thereby relieving the interference with the friction ring 3016. That is, after the pressing of the two pressing blocks 3011 is stopped, if the torsion sleeve 309 rotates again, it will not drive the adjusting screw 307 to rotate. Therefore, the compression inner wire tube 301 will not move upward or downward, thereby preventing the torsion sleeve 309 from rotating and causing damage to the patient's radial artery wound again, thereby improving the safety and protection of hemostasis.

[0053] When the bottom of the hemostatic plate 304 contacts the wound site of the radial artery of the patient, as the hemostatic plate 304 applies pressure to the wound site of the radial artery of the patient, the airbag 404 is compressed and deflated by the reaction force of the wound site of the radial artery of the patient, and the air inside the airbag 404 is pressed into the inside of the two air distribution channels 401 through the main air pipe 403 and the main air channel 402, and then discharged into the inside of the two cylinders 407 through the two air distribution pipes 4012, so that the pressure inside the two cylinders 407 increases, and the two piston rods 408 are pushed upward, and the clamping plate 3013 drives the brake plate 4013 to rotate together with the rotation of the torsion sleeve 309, so that it is blocked by the upward piston column 408 and stops rotating, so as to prevent the hemostatic plate 304 from exerting too much pressure on the wound of the patient;

[0054] After hemostasis is completed, the medical staff presses the two pressing blocks 3011, and pushes the two clamping plates 3013 and the two friction shoes 3014 toward the outer wall of the friction ring 3016 through the connecting action of the push rod 3012, until the two friction shoes 3014 collide with the outer wall of the friction ring 3016, and then rotates the torsion sleeve 309 in the opposite direction. Since the top of the piston column 408 is provided with an inclined surface 409, the reversal of the clamping plate 3013 drives the brake plate 4013 to reverse, and the piston column 408 is pushed downward under the action of the wedge force between the bottom of the brake plate 4013 and the inclined surface 409, so as not to affect the reversal of the torsion sleeve 309, and thus the present invention can be conveniently removed after hemostasis.

[0055] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
