Description

Technical Field

[0001] The present invention relates to the technical field of hemostatic devices, and particularly to an arterial compression hemostatic device. Background Art

[0002] In current disease treatment methods, the radial artery is often used for surgeries, especially for some coronary heart disease patients. Percutaneous transluminal coronary angioplasty (PTCA) has become one of the main treatment methods for coronary heart disease, and the puncture access is generally the radial artery puncture method. Currently, a radial artery compression hemostatic device is generally used for hemostasis after radial artery puncture. The radial artery compression hemostatic device includes a balloon compression type and a spiral compression type. Among them, the spiral compression type arterial compression device is shown in the patent documents with publication numbers CN213465190U, CN203953735U, and CN219271032U.

[0003] Among them, the existing spiral compression type arterial compression device generally includes a base plate, a screw rod, a compression head, a strap, and a spiral cap. When in use, the spiral type arterial compression device is first fixed on the patient's wrist through the strap, so that the compression head is directly above the radial artery puncture point, and then the spiral cap is rotated to drive the screw rod to rotate and drive the compression head to move downward at the same time, applying appropriate pressure to the radial artery to block blood flow, thereby achieving the effect of hemostasis.

[0004] Since the screw rod of the existing spiral compression type arterial compression device is rotatable, it is easy to drive the compression head to shift. If the compression head shifts and does not align with the radial artery puncture point, the blood vessel rupture opening cannot be effectively compressed, resulting in hemostasis failure, which may cause continuous bleeding or subcutaneous hematoma.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0022] As Figures 1 - 6 shown, an embodiment of the present invention provides an arterial compression hemostat, which includes a bottom box 1, a compression member, a lifting member, a guiding member, a rope redirecting mechanism, a reset mechanism, two winding disks, a rope 30, and a driving device. An installation space is formed inside the bottom box 1, and an access hole for the compression member to pass through is provided on the inner bottom wall of the bottom box 1; the two winding disks are arranged and installed on the top of the bottom box 1 along a first direction; the guiding member is vertically installed on the inner top wall of the bottom box 1, the lifting member is slidably installed on the guiding member, the compression member is installed on the lifting member and is lower than the lifting member; after the rope 30 passes through the lifting member and passes through the rope redirecting mechanism, both ends of the rope 30 are respectively fixed to the two winding disks; the driving device is used to drive the two winding disks to rotate synchronously in the same direction to wind or unwind both ends of the rope 30; when the driving device drives the two winding disks to tighten the rope 30, the lifting member drives the compression member to descend under the drive of the rope 30 to extend out of the access hole; when the driving device drives the two winding disks to loosen the rope 30, the lifting member drives the compression member to rise under the action of the reset mechanism, thereby gradually reducing the compression.

[0023] In this embodiment, when using this arterial compression hemostat, first fix this arterial compression hemostat on the patient's wrist through a strap, and make the compression member located directly above the radial artery puncture point, and then use the driving device to drive the two winding disks to rotate synchronously in the same direction to wind the rope 30. As the rope 30 is gradually tightened, the rope 30 drives the lifting member to move downward along the guiding member to drive the compression member to descend. The compression member extends out of the access hole at the bottom of the bottom box 1 and compresses the radial artery puncture point, applying an appropriate pressure to the radial artery to block blood flow, thereby achieving the effect of hemostasis. When it is necessary to relieve the pressure applied to the radial artery, use the driving device to drive the two winding disks to rotate synchronously in the same direction to loosen the rope 30. Under the action of the reset mechanism, the lifting member drives the compression member to rise, so that the compression member gradually reduces the compression on the radial artery.

[0024] Compared with the traditional spiral arterial compression hemostat, this arterial compression hemostat has at least the following advantages: First: By driving the two winding disks to synchronously tighten the rope 30 through the driving device, the lifting member slides along the guiding member, and the compression member is only subjected to a vertically downward force, avoiding the risk of lateral displacement and ensuring that the compression head always aligns with the puncture point. And due to the limiting effect of the guiding member on the lifting member, the lifting member can only drive the compression member to move vertically downward along the guiding member, eliminating the phenomenon of lateral displacement of the compression member.

[0025] Second: The process of winding the rope 30 is a continuous and progressive pressure application, and the action is softer, reducing the probability of secondary damage to blood vessels and surrounding tissues.

[0026] It should be noted that the rope 30 in this embodiment is a steel wire rope and is not easily deformed.

[0027] In this embodiment, the inlet and outlet holes are located at the middle position of the bottom of the bottom box 1. On the inner bottom wall of the bottom box 1, two first mounting seats 9 are arranged and mounted along the first direction (the length direction of the bottom box 1). These two first mounting seats 9 are respectively located on the left and right sides of the inlet and outlet holes, and the two first mounting seats 9 are symmetrically arranged with respect to the inlet and outlet holes. On the inner top wall of the bottom box 1, two second mounting seats 34 are arranged and mounted along the first direction. The two second mounting seats 34 have the same height, and the two second mounting seats 34 are symmetrically arranged with respect to the inlet and outlet holes. The projection of the second mounting seats 34 in the direction towards the inner bottom wall of the bottom box 1 is located between the two first mounting seats 9.

[0028] For the convenience of description, the two winding discs are respectively named the first winding disc 15 and the second winding disc 17. The first winding disc 15 and the second winding disc 17 are symmetrically arranged with respect to the inlet and outlet holes, and the projections of the first winding disc 15 and the second winding disc 17 in the downward direction are located between the two second mounting seats 34.

[0029] In this embodiment, the rope redirecting mechanism includes a first guide wheel disc 19, a second guide wheel disc 20, a third guide wheel disc 21 and a fourth guide wheel disc 22. Among them, the first guide wheel disc 19 is mounted on the second mounting seat 34 located on the right side of the inlet and outlet holes, the second guide wheel disc 20 is mounted on the first mounting seat 9 located on the right side of the inlet and outlet holes, the third guide wheel disc 21 is mounted on the first mounting seat 9 located on the left side of the inlet and outlet holes, and the fourth guide wheel disc 22 is mounted on the second mounting seat 34 located on the left side of the inlet and outlet holes.

[0030] That is, in this embodiment, the second winding disc 17, the first guide wheel disc 19, and the second guide wheel disc 20 are respectively symmetrically arranged with respect to the inlet and outlet holes of the bottom box 1 with the first winding disc 15, the fourth guide wheel disc 22, and the third guide wheel disc 21. Thus, when the two winding discs rotate synchronously, the rope 30 can stably and continuously press down the lifting member.

[0031] In this embodiment, a first support seat 10 and a second support seat 11 are mounted on the top surface of the bottom box 1. A first shaft body 12 and a second shaft body 13 are respectively rotatably mounted on the first support seat 10 and the second support seat 11. The first winding disc 15 and the second winding disc 17 are respectively coaxially mounted on the first shaft body 12 and the second shaft body 13. It should be noted that the first winding disc 15 and the second winding disc 17 have exactly the same size, and the diameters of the first shaft body 12 and the second shaft body 13 are the same.

[0032] Among them, the driving device includes a gear transmission mechanism, an input shaft, and a shaft locking device 8. The input shaft is connected to the gear transmission mechanism, and the gear transmission mechanism is used to drive the first winding disc 15 and the second winding disc 17 to rotate synchronously in the same direction; the shaft locking device 8 is mounted on the input shaft for locking or loosening the input shaft.

[0033] In this embodiment, the gear transmission mechanism includes a first driven gear 14, a second driven gear 16, and a driving gear 18. Among them, the first driven gear 14 and the second driven gear 16 are respectively installed on a first shaft body 12 and a second shaft body 13, and the first driven gear 14 and the second driven gear 16 are exactly the same. A third support seat is provided between the first support seat 10 and the second support seat 11, and the driving gear 18 is rotatably installed on the third support seat. The first driven gear 14 and the second driven gear 16 are respectively engaged with the driving gear 18. One end of the input shaft is connected to the driving gear 18, and a shaft locking device 8 is installed on the input shaft for locking or loosening the input shaft.

[0034] In this embodiment, as Figure 2 shown, a top box 2 is installed on the top of the bottom box 1. The top box 2 covers the entire gear transmission mechanism, the first winding disc 15, the second winding disc 17, the first support seat 10, the second support seat 11, the third support seat, etc., to prevent external dust from falling on the gear set.

[0035] As Figure 2 shown, a shaft locking device 8 is installed on the outer side wall of the top box 2. One end of the input shaft away from the driving gear 18 passes through the top box 2. The shaft locking device 8 cooperates with the input shaft to lock or loosen the input shaft. A rotating head 7 is installed at the end of the input shaft away from the driving gear 18 to facilitate the rotation of the input shaft.

[0036] In this embodiment, the lifting member includes a lifting block 24, two connecting plates 26, and two connecting shafts 25. A round hole for the rope 30 to pass through is formed in the lifting block 24, and the round hole extends along the length direction of the bottom box 1. The two connecting plates 26 are arranged along the second direction on the lifting block 24. The second direction is the width direction of the bottom box 1. The connecting plates 26 correspond to the connecting shafts 25 one by one. The connecting shafts 25 are installed on the side of the corresponding connecting plates 26 away from the lifting block 24. A vertically arranged vertical plate 27 is installed at one end of each connecting shaft 25 away from the lifting block 24, and the bottom surface of the vertical plate 27 is lower than the lifting block 24; the pressing member includes a pressing block 28, and the bottom of the vertical plate 27 is connected to the pressing block 28.

[0037] In some embodiments, the guiding member includes at least one guiding rod 23. The guiding rod 23 is vertically installed on the inner top wall of the bottom box 1. A round hole for the guiding rod 23 to pass through is formed in the connecting plate 26. The bottom end of the guiding rod 23 passes through the round hole on the connecting plate 26, so that the lifting member can only move vertically along the guiding rod 23, thereby restricting the moving direction of the lifting member and the pressing block 28, and preventing the pressing block 28 from moving horizontally.

[0038] In some embodiments, four guiding rods 23 are provided, and a round hole for the guiding rod 23 to pass through is provided at both ends of each connecting plate 26.

[0039] In some embodiments, the reset mechanism includes a spring 31. As Figure 3 shown, the top end of the spring 31 is fixedly connected to the inner top wall of the bottom box 1, and the bottom end of the spring 31 is connected to the lifting block 24 or the connecting plate 26.

[0040] Thus, after the arterial compression hemostat is fixed on the patient's wrist through a strap and the compression member is located directly above the radial artery puncture point, by rotating the rotating head 7 to drive the input shaft to rotate, the input shaft drives the driving gear 18 to rotate. Since the first driven gear 14 and the second driven gear 16 are respectively engaged with the driving gear 18, the first driven gear 14 and the second driven gear 16 can be driven to rotate synchronously in the same direction around the same axis, thereby synchronously tightening both ends of the rope 30. As the rope 30 is gradually tightened, the portion of the rope 30 between the second guide wheel disc 20 and the third guide wheel disc 21 gradually tightens and drives the lifting member to move downward along the guide rod 23. The lifting member drives the compression member to descend, and the compression member extends out of the access hole at the bottom of the bottom box 1 and compresses the radial artery puncture point, applying an appropriate pressure to the radial artery to block blood flow, thereby achieving the effect of hemostasis. Finally, the shaft locking device 8 is used to lock the input shaft to prevent the input shaft from rotating self, thereby preventing the two winding discs from rotating self, so as to ensure that the radial artery puncture point can be compressed with a stable and continuous pressure.

[0041] When it is necessary to relieve the pressure applied to the radial artery, the user holds the rotating head 7, then releases the locking effect of the shaft locking device 8 on the input shaft. The user feels the compression force on the radial artery puncture point and appropriately relaxes the holding force on the rotating head 7. Under the action of the rope 30, the second guide wheel disc 20 and the third guide wheel disc 21 rotate synchronously in the opposite direction, thereby gradually relaxing the rope 30. Until the compression force of the compression block 28 on the radial artery puncture point reaches an appropriate level, the user tightly holds the rotating head 7 to prevent the input shaft from rotating self and at the same time uses the shaft locking device 8 to lock the input shaft again.

[0042] When it is necessary to relieve the pressure applied to the radial artery, it is only necessary to release the locking effect of the shaft locking device 8 on the input shaft.

[0043] In some embodiments, as Figure 6 shown, the reset mechanism includes a first magnetic block 32 and a second magnetic block 33 that attract each other. The first magnetic block 32 and the second magnetic block 33 are in one-to-one correspondence. The first magnetic block 32 is installed on the top of the connecting plate 26, and the second magnetic block 33 is installed on the inner top wall of the bottom box 1. The second magnetic block 33 is located directly above the corresponding first magnetic block 32. Thus, when relieving the compression, the second magnetic block 33 attracts the first magnetic block 32 to drive the compression block 28 to rise.

[0044] It should be noted that the number of the first magnetic block 32 and the second magnetic block 33 is not specifically limited. For example, one first magnetic block 32 and one second magnetic block 33 are respectively provided, or two first magnetic blocks 32 and two second magnetic blocks 33 are respectively provided.

[0045] In order to accurately understand the pressure exerted by the pressing block 28 on the radial artery, optionally, an installation counterbore is provided on the lower surface of the pressing block 28, and a pressure sensor is installed in the installation counterbore. The measuring head of the pressure sensor is slightly lower than the lower surface of the pressing block 28. A microcontroller is installed in the internal space of the bottom box 1. The microcontroller is signal-connected to the pressure sensor. A display is installed on the front or top of the bottom box 1, and the display is signal-connected to the microcontroller. In this way, when the pressing block 28 exerts an appropriate pressure on the radial artery, the pressure sensor sends the detected pressure value to the microcontroller in real time and displays it through the display, so that the user can accurately adjust the appropriate pressure exerted on the radial artery according to the pressure value.

[0046] In some embodiments, two ropes 30 are provided. The above-mentioned first mounting seat 9, second mounting seat 34, first guide wheel disc 19, second guide wheel disc 20, third guide wheel disc 21, fourth guide wheel disc 22, first winding disc 15 and second winding disc 17 are all provided with two. Two first winding discs 15 are installed on the first shaft body 12, and two second winding discs 17 are installed on the second shaft body 13. Both of the two ropes 30 pass through the lifting block 24, and both ends of the two ropes 30 bypass a plurality of guide wheel discs and are respectively fixed on the first winding disc 15 and the second winding disc 17. In this way, when the rotating head 7 is rotated to drive the input shaft to rotate self, the input shaft drives the driving gear 18 to rotate, so as to drive the first driven gear 14 and the second driven gear 16 to rotate synchronously in the same direction, so that the two first winding discs 15 and the two second winding discs 17 rotate to synchronously tighten the two ropes 30, so as to more stably press the puncture point.

[0047] In some embodiments, a soft pressing block 29 is provided on the lower surface of the pressing block 28. The soft pressing block 29 is soft in texture and is not likely to scratch or abrade the skin like a hard material when contacting the skin. When pressing and stopping bleeding of the radial artery, the soft pressing block 29 can play a certain buffering role, making the patient feel more comfortable during the process of wearing the hemostat and reducing the discomfort caused by compression.

[0048] In this embodiment, a strap assembly is further included. The strap assembly of the present application can be a commonly used strap in an arterial compression hemostat, such as a magic tape strap or a wristband strap.

[0049] Optionally, as Figure 2As shown in the figure, two bending plates 101 are respectively provided at both ends of the bottom box 1. The two bending plates 101 are arranged along the width direction of the bottom box 1, and there is a gap between the two bending plates 101. The bending plate 101 bends towards the middle position of the bottom box 1 and forms a hook shape. Further, the strap assembly includes a wristband 6 and two quick connectors. The quick connector includes a hanging shaft 3, a connecting rod 4 and a loop 5 which are connected to each other. The hanging shaft 3 and the connecting rod 4 are perpendicular to each other. The wristband 6 is a Velcro wristband.

[0050] When in use, as Figure 2 shown in the figure, first buckle the hanging shafts 3 of the two quick connectors into the bending plates 101 on both sides of the bottom box 1. The connecting rod 4 is located between two adjacent bending plates 101. Then pass the two ends of the wristband 6 through the two loops 5 respectively and adjust the tightness. Finally, use the Velcro on the surface of the wristband 6 to stick tightly. Since the hanging shaft 3 can be disassembled at any time, the strap assembly can be disassembled at any time, making it more convenient to use.
