Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a compression device for femoral artery puncture. Background Art

[0002] Femoral artery puncture is a common medical procedure, usually used for cardiovascular angiography, stent implantation, etc. After femoral artery puncture, in order to stop bleeding and prevent complications, a femoral artery puncture compressor is often used, which helps stop bleeding by applying continuous and stable pressure, thereby reducing the risk of bleeding and hematoma.

[0003] The usage process of the existing technology is to first place the comfort board at the bottom of the thigh near the buttocks, then take out the He's pad and aseptically put it on the hemostat, then place the hemostat on the patient's thigh, and make the He's pad press directly above the blood vessel puncture port, and then manually pass the hemostat through the straps on both sides of the comfort board and fix the hemostat, and finally start the hemostat to drive the He's pad to squeeze to achieve the hemostatic effect.

[0004] In the above workflow, when the hemostat relies on manual strapping to fix it on the top of the thigh, it is difficult to ensure the constant and appropriate strength of the strapping. If it is too tight, it may hinder blood circulation and increase the risk of limb injury; if it is too loose, it may lead to incomplete hemostasis and cause the risk of bleeding again. Secondly, the lack of a precise control mechanism makes each binding a test of the experience and skills of medical staff, making it difficult to achieve standardized operations, which increases the uncertainty in the medical process. Summary of the invention

[0005] The main purpose of the present invention is to provide a femoral artery puncture compressor, which solves the problem that it is difficult to ensure the strength of the bandage during manual operation by providing a winding mechanism and a clamping mechanism.

[0006] To achieve the above object, the present invention provides the following technical solutions: A compression device for femoral artery puncture, comprising a comfort plate with straps connected on both sides, and further comprising: The outer shell has a stabilizing plate at the bottom of one end of the outer shell that fits the top of the thigh; A hemostasis mechanism, which is arranged at the bottom of the other end of the outer shell; The winding mechanism includes a left winding member and a right winding member arranged on the outer wall of the outer shell, the left winding member includes a mounting frame fixedly connected to the outer wall of the outer shell, a rotating shaft penetrating the mounting frame and rotatably connected to the side wall of the mounting frame, and a winding drum fixedly connected to the outer wall of the rotating shaft; The clamping mechanism comprises a first clamping member and a second clamping member fixedly connected to the inner wall of the winding drum, wherein the first clamping member comprises a connecting shaft fixedly connected to the inner wall of the winding drum, and a clamping plate rotatably connected to the outer wall of the connecting shaft.

[0007] Preferably, the winding mechanism further comprises a through hole formed in the side wall of the outer shell, and a double-headed motor fixedly connected to the inner wall of the through hole, wherein the two output shafts of the double-headed motor rotate in opposite directions and have the same rotation speed.

[0008] Preferably, the left winding member further comprises a first pulley fixedly connected to the outer side wall of the rotating shaft, and a second pulley fixedly connected to the outer side wall of the double-headed motor output shaft, and the first pulley is connected to the second pulley via a belt.

[0009] Preferably, the right winding member and the left winding member have the same composition structure, and the two are distributed in a ring array, and the second pulley of the right winding member is fixedly connected to another output shaft driven by the double-headed motor.

[0010] Preferably, the first clamping member further comprises a protrusion fixedly connected to the bottom of the clamping plate, and an inclined plate fixedly connected to the end surface of the clamping plate; The second clamping member has the same structure as the first clamping member, the two groups of clamping plates are arranged in parallel, and the two groups of protrusions are arranged in a staggered manner.

[0011] Preferably, the clamping mechanism further comprises an electric push rod fixedly connected to the inner side wall of the winding drum, a transmission plate fixedly connected to the output end of the electric push rod, and two rollers rotatably connected to both ends of the transmission plate.

Because the positions of the protrusions are staggered, the fixing ability of the straps can be improved.

[0014] 2. In the present invention, the double-headed motor is started to drive the two second pulleys to rotate, and then the two first pulleys to rotate, thereby driving the rotating shaft and the winding drum to rotate, so as to reel up the bandage. When the bandage is reeled to a certain position, the bandage will begin to tighten, thereby slowing down the speed of the double-headed motor until the speed sensor detects that the speed of the double-headed motor reaches the set value.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figure 1-5 As shown, a compression device for femoral artery puncture includes a comfort plate with straps connected on both sides, and also includes: An outer shell 1, a stabilizing plate 2 is provided at the bottom of one end of the outer shell 1 to fit the top of the thigh; Preferably, the outer shell 1 can be made of PE plastic; A hemostasis mechanism, which is arranged at the bottom of the other end of the outer shell 1; The winding mechanism includes a left winding member and a right winding member arranged on the outer wall of the outer shell 1, the left winding member includes a mounting frame 401 fixedly connected to the outer wall of the outer shell 1, a rotating shaft 402 penetrating the mounting frame 401 and rotatably connected to the side wall of the mounting frame 401, and a winding drum 403 fixedly connected to the outer wall of the rotating shaft 402, wherein all components of the winding mechanism are made of PP plastic; The clamping mechanism includes a first clamping member and a second clamping member fixedly connected to the inner wall of the winding drum 403. The first clamping member includes a connecting shaft 501 fixedly connected to the inner wall of the winding drum 403, and a clamping plate 502 rotatably connected to the outer wall of the connecting shaft 501.

[0019] The first clamping member further includes a protrusion 503 fixedly connected to the bottom of the clamping plate 502, and an inclined plate 504 fixedly connected to the end surface of the clamping plate 502; The second clamping member has the same structure as the first clamping member, the two groups of clamping plates 502 are arranged in parallel, and the two groups of protrusions 503 are arranged in a staggered manner, wherein the protrusions 503 are made of rubber material, and the inclined plates 504 and the clamping plates 502 are made of plastic plates.

[0020] The clamping mechanism also includes an electric push rod 505 fixedly connected to the inner wall of the winding drum 403, a transmission plate 506 fixedly connected to the output end of the electric push rod 505, and two rollers 507 rotatably connected to the two ends of the transmission plate 506. The inclined plate 504 is made of ferromagnetic material, and the roller 507 is composed of a cylindrical magnet and a rubber sleeve wrapped around the outer wall of the cylindrical magnet. The electric push rod 505 drives the transmission plate 506 to move toward the clamping plate 502, thereby pushing the two inclined plates 504 to rotate outward, thereby making the two clamping plates 502 perform circular motions in opposite directions. When the electric push rod 505 drives the transmission plate 506 away from the clamping plate 502, the clamping plate 502 will be reset under the action of the magnetic force.

[0021] First, place the comfort plate at the bottom of the thigh near the buttocks, then take out the He's pad and aseptically put it on the extrusion head 301, then place the hemostat on the patient's thigh, and make the He's pad press directly above the blood vessel puncture port, and then insert the straps on both sides of the comfort plate into the notch of the winding drum 403 respectively, and then start the electric push rod 505 to drive the transmission plate 506 to move in the direction of the clamping plate 502, and then push the two inclined plates 504 to rotate outward, so that the two clamping plates 502 make circular motions towards each other, and start the two protrusions 503 to press against the two sides of the strap. Because the positions of the protrusions 503 are staggered, the fixing ability of the strap can be improved.

[0022] Embodiment 2: Figure 1-5 As shown, a compression device for femoral artery puncture includes a comfort plate with straps connected on both sides, and also includes: An outer shell 1, a stabilizing plate 2 is provided at the bottom of one end of the outer shell 1 to fit the top of the thigh; A hemostasis mechanism, which is arranged at the bottom of the other end of the outer shell 1; The winding mechanism includes a left winding member and a right winding member arranged on the outer wall of the outer shell 1, the left winding member includes a mounting frame 401 fixedly connected to the outer wall of the outer shell 1, a rotating shaft 402 penetrating the mounting frame 401 and rotatably connected to the side wall of the mounting frame 401, and a winding drum 403 fixedly connected to the outer wall of the rotating shaft 402; The clamping mechanism includes a first clamping member and a second clamping member fixedly connected to the inner wall of the winding drum 403. The first clamping member includes a connecting shaft 501 fixedly connected to the inner wall of the winding drum 403, and a clamping plate 502 rotatably connected to the outer wall of the connecting shaft 501.

[0023] The winding mechanism also includes a through hole opened in the side wall of the outer shell 1, and a double-headed motor 405 fixedly connected to the inner wall of the through hole. The two output shafts of the double-headed motor 405 rotate in opposite directions and have the same rotation speed. The inner wall of the through hole is provided with a Hall sensor for detecting the output shaft rotation speed, which is not drawn in the figure.

[0024] The left winding member also includes a first pulley 404 fixedly connected to the outer wall of the rotating shaft 402, and a second pulley 406 fixedly connected to the outer wall of the output shaft of the double-headed motor 405. The first pulley 404 is connected to the second pulley 406 by a belt, and the output shaft is driven to rotate by the double-headed motor 405, which in turn drives the second pulley 406 and the first pulley 404 to rotate, thereby driving the winding drum 403 to rotate.

[0025] The right winding member and the left winding member have the same structure, and the two are arranged in a ring array. The second pulley 406 of the right winding member is fixedly connected to another output shaft driven by the double-headed motor 405.

[0026] The hemostasis mechanism includes an electric telescopic rod 302 fixedly connected to the bottom of the shell, an extrusion head 301 fixedly connected to the output end of the electric telescopic rod 302, and a pressure sensor 303 fixedly connected to the bottom of the extrusion head 301. The pressure sensor 303 is used to monitor the pressure of the extrusion head 301 on the thigh, and when the set value is reached, the electric telescopic rod 302 is closed.

[0027] When the bandage is fixed, the double-headed motor 405 is started to drive the two second pulleys 406 to rotate, and then the two first pulleys 404 are driven to rotate, so as to drive the rotating shaft 402 and the winding drum 403 to rotate, so as to roll up the bandage. When the bandage is rolled to a certain position, the bandage will begin to tighten, so that the speed of the double-headed motor 405 slows down until the speed sensor detects that the speed of the double-headed motor 405 reaches the set value. At this time, the double-headed motor 405 is turned off, so that the device is fixed on the top of the thigh, and the binding force is constant at an appropriate level. Finally, the electric telescopic rod 302 is started to drive the extrusion head 301 to move down and hold it above the puncture port. At this time, the pressure sensor 303 is used to monitor the pressure of the extrusion head 301 on the thigh, and when the set value is reached, the electric telescopic rod 302 is turned off to ensure the accurate control of the pressure. When use is completed, the double-headed motor 405 is unlocked and the bandage is pulled until the bandage is separated from the reel 403. The transmission plate 506 is then reset by the electric push rod 505. At this time, the tilting plate 504 will not be able to clamp the bandage, so the device can be separated from the patient's thigh. Finally, the He's pad is removed and the stabilizing plate 2 is disinfected to ensure the safety and hygiene of the device in the next cycle of use.
