A pressure-adjustable hemostatic device

Abstract

This invention belongs to the field of medical device technology, specifically a pressure-adjustable hemostatic device, including a main positioning component, an operating component mounted on top of the main positioning component, a hemostatic component installed inside the operating component, and arm clamping components on both sides of the main positioning component. This invention uses an inflation tube to remove airflow from the inside of the air-filled hemostatic block. Then, the endotracheal transmission rod drives the arc-shaped groove block to rotate clockwise. The arc-shaped track of the arc-shaped groove block guides a movable push block to move outward along a vertical slide groove. The movable push block, in turn, moves the air-filled hemostatic block outward. Medical personnel can use sterile cotton swabs to clean the patient's skin at that location by passing them between the air-filled hemostatic block and the annular hollow frame. The cotton swabs can also clean the bottom of the air-filled hemostatic block, thus ensuring a safer environment around the radial artery and improving the safety of radial artery compression hemostasis.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a pressure-adjustable hemostatic device. Background Technology

[0002] Radial artery puncture is a common approach in cardiovascular interventional procedures (such as coronary angiography and PCI). Hemostasis is a core aspect of surgical procedures and trauma management, and postoperative pressure must be applied to the puncture site for hemostasis (usually for 6-8 hours). Traditional hemostasis methods (manual pressure, elastic bandages) suffer from problems such as uncontrollable pressure and unstable hemostatic effects. In contrast, pressure-adjustable hemostatic devices achieve precise pressure regulation through mechanical or electronic control, significantly improving the safety of hemostasis and patient comfort.

[0003] A search revealed that patent CN220404066U discloses an adjustable radial artery compression hemostat, comprising a clamping block, an arc-shaped block, a flexible band, and a compression structure. When using this hemostat, the compression block is first aligned with the radial artery compression point of the patient after surgery. Then, the two arc-shaped positioning blocks are positioned to avoid the ulnar artery and adhere to the skin surface of the patient's arm, so that the patient's ulnar artery is located between the lower ends of the two clamping blocks. Finally, the flexible band passes through through slot three, through slot four, and through slots one and two in sequence and is tightened and bonded to fix the hemostat to the patient's arm. The gap between the lower ends of the two clamping blocks will not compress the patient's ulnar artery, thereby improving the safety and comfort of hemostasis for the patient.

[0004] The aforementioned hemostatic device is fixed using traditional elastic bandages or Velcro. However, if the patient moves their arm immediately after the surgery, the force between the puncture point and the compression block may shift, potentially causing bleeding. Since the compression block is fixed, the bleeding passes through it and is exposed to the air. Furthermore, if bleeding persists around the puncture point for a long time, it can easily lead to wound infection. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure-adjustable hemostatic device to solve the problems mentioned in the background art.

A bidirectional positioning rod is fixedly installed between the arc-shaped groove block and the vertical sliding grooves. A movable push block is fixedly installed on the outer side of the bidirectional positioning rod. The movable push block is slidably installed on the outer wall of the annular hollow frame. An airbag hemostatic block is fixedly installed on one side of the movable push block that passes through the annular hollow frame. The airbag hemostatic block is connected to the inflation tube. A pressure hemostatic block is fixedly installed at the bottom of the annular hollow frame.

[0010] Optionally, the operating component further includes a rectangular positioning block fixedly installed on the top of the positioning plate, and two positioning plates are fixedly installed on the side of the rectangular positioning block facing the hollow slide bar frame.

[0011] Optionally, a rack block is fixedly installed on the side of the hollow slide bar frame facing the rectangular positioning block, and a hollow sliding groove gear ring is rotatably installed inside the two positioning plates, wherein the hollow sliding groove gear ring is set in a meshing state with the rack block.

[0012] Optionally, a threaded positioning rod is installed inside the rectangular positioning block. A hollow sliding rod is fixedly installed on one side of the threaded positioning rod, which passes through the rectangular positioning block and is located inside the rectangular positioning block. The hollow sliding rod is slidably installed inside the positioning plate.

[0013] Optionally, the hollow grooved gear ring has two grooves inside, and the hollow grooved gear ring is slidably installed on the outside of the hollow grooved rod through the two grooves.

[0014] Optionally, the arm clamping assembly includes two rotating rods rotatably mounted on both sides of the positioning plate, an arc-shaped clamping block is fixedly mounted on the outer side of the rotating rod, and a clamping handle is fixedly mounted on the top of the arc-shaped clamping block.

[0015] Optionally, a spring is fixedly installed between the arc-shaped clamping block and the positioning plate, and a filled airbag is fixedly installed on the inner wall of the arc-shaped clamping block through an opening.

[0016] Optionally, two sets of hollow triangular positioning blocks are fixedly installed on both sides of the positioning plate, and a limit ring is fixedly installed on one side of the rotating rod that passes through the hollow triangular positioning block.

[0017] Optionally, a slotted rod is fixedly installed on one side of the rotating rod passing through the hollow triangular positioning block. Hollow slide rails are provided on the upper and lower sides of the slotted rod. A multi-toothed ring sleeve is slidably installed on the outer side of the slotted rod through the hollow slide rails. A multi-toothed hole is provided on the outer side of the hollow triangular positioning block, and the multi-toothed hole is adapted to the multi-toothed ring sleeve.

[0018] Optionally, the positioning base assembly includes two sets of telescopic blocks hinged to the bottom of the arc-shaped clamping block, an insertion slot block is slidably installed between the two sets of telescopic blocks, and a side positioning block is fixedly installed on the top of the telescopic block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When using this invention, medical staff first use the inflation tube to remove the airflow inside the airbag hemostatic block. Then, the tracheal transmission rod drives the arc-shaped groove block to rotate clockwise. The arc-shaped track of the arc-shaped groove block guides the movable push block to move outward along the vertical slide. The movable push block drives the airbag hemostatic block to move outward. Medical staff can pass a sterile cotton swab between the airbag hemostatic block and the ring hollow frame to clean the patient's skin at that location. At the same time, the sterile cotton swab can also clean the bottom of the airbag hemostatic block, thereby ensuring a safer environment around the radial artery and improving the safety of the radial artery when applying pressure for hemostasis.

[0021] 2. When the threaded positioning rod moves to one side along the rectangular positioning block via the thread, it simultaneously drives the hollow sliding toothed ring to rotate synchronously along the positioning plate. The hollow sliding toothed ring then pushes the hollow sliding rod frame downward along the ring-shaped positioning frame through meshing with the rack block, until the pressure hemostatic block compresses the patient's radial artery to stop bleeding, thereby improving the stability of the pressure hemostatic block in stopping bleeding in the radial artery. At the same time, it can effectively stop bleeding and compress the radial artery for different patients.

[0022] 3. After the arc-shaped clamping block is positioned, the medical staff slides the multi-toothed ring along the rotating rod. The multi-toothed ring is inserted into the multi-toothed hole, and the arc-shaped clamping block is limited and cannot move further. Then, the two side positioning blocks and the pressure hemostatic block clamp the patient's arm, so that the patient's skin does not need to come into contact with too much clamping material, improving the patient's comfort. At this time, the medical staff can inflate the air bladder of the arc-shaped clamping block, so that the air bladder fits and clamps the patient's arm skin, further improving the patient's comfort.

Detailed Implementation

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figure 1 , Figures 6-9 As shown, the present invention proposes a pressure-adjustable hemostatic device, including a main positioning component 1, an operating component 2 mounted on the top of the main positioning component 1, a hemostatic component 3 mounted inside the operating component 2, and arm clamping components 4 arranged on both sides of the main positioning component 1. In use, the operating component 2 is placed facing the radial artery, while the arm clamping components 4 can avoid the patient's ulnar artery and fit against the patient's arm skin surface. The hemostatic component 3 passes through the operating component 2 and abuts against the puncture point of the patient's radial artery. The positioning base component 5 abuts against the skin surface of the patient on the side away from the radial artery, thereby wrapping and positioning the peripheral part of the patient's radial artery, improving the stability of the present invention installed on the peripheral part of the patient's radial artery.

[0041] Furthermore, the main positioning component 1 includes a positioning plate 101, and the operating component 2 includes an open-ring positioning frame 201 fixedly installed on the top of the positioning plate 101. The open-ring positioning frame 201 is located on the side away from the radial artery and is mainly used to guide the movement of the hemostasis component 3 without contacting the radial artery. The operating component 2 also includes a rectangular positioning block 202 fixedly installed on the top of the positioning plate 101. Two positioning plates 206 are fixedly installed on the side of the rectangular positioning block 202 facing the hollow slide bar frame 304, and a rack block 305 is fixedly installed on the side of the hollow slide bar frame 304 facing the rectangular positioning block 202. A hollow grooved toothed ring 204 is rotatably installed inside the block positioning plate 206. The hollow grooved toothed ring 204 has two grooves inside. The hollow grooved toothed ring 204 is slidably installed on the outside of the hollow grooved rod 205 through the two grooves. The hollow grooved toothed ring 204 is set in a meshing state with the rack block 305. A hollow slide rod frame 304 is slidably installed inside the ring-shaped positioning frame 201. A ring-shaped hollow frame 301 is fixedly installed on one side of the hollow slide rod frame 304 that passes through the ring-shaped positioning frame 201. A pressure hemostatic block 302 is fixedly installed at the bottom of the ring-shaped hollow frame 301.When locating the radial artery, due to significant differences in wrist circumference and thickness among patients, and the fact that the pressure hemostatic block 302 is normally some distance from the radial artery, medical staff manually rotate the threaded positioning rod 203. The threads on both sides of the rectangular positioning block 202 are both positive threads. When the threaded positioning rod 203 rotates counterclockwise, it moves to one side along the rectangular positioning block 202 via the threads, simultaneously causing the hollow grooved toothed ring 204 to rotate synchronously along the positioning plate 206. The hollow grooved toothed ring 204, through engagement with the rack block 305, pushes the hollow slide bar frame 304 downwards along the ring-shaped positioning frame 201 until the pressure hemostatic block 302 compresses and stops the bleeding from the radial artery. Simultaneously, nuts (not shown in the figure) are rotatably installed at both ends of the threaded positioning rod 203 passing through the rectangular positioning block 202, and both nuts are located on the outside of the rectangular positioning block 202. 3. After rotating to the designated position, medical staff rotate the two nuts respectively until both nuts are attached to the outer wall of the rectangular positioning block 202. If the patient's arm moves, the radial artery may exert a reverse thrust on the hollow slide bar frame 304. The thrust will cause the hollow slide groove gear ring 204 and the hollow slide groove rod 205 to rotate. Since the threaded positioning rod 203 will move within the rectangular positioning block 202 by rotation, and the thread directions on both sides of the rectangular positioning block 202 are the same, the movement directions of the two threaded positioning rods 203 are also the same. At this time, no matter which direction the threaded positioning rod 203 moves, it will be limited by the nut set on the side opposite to its movement direction and the rectangular positioning block 202. This will prevent the hollow slide bar frame 304 and the pressure hemostatic block 302 from moving, thereby improving the stability of the pressure hemostatic block 302 in the hemostasis positioning of the radial artery. At the same time, it can effectively stop the hemostasis and compress the radial artery for different patients.

[0042] Furthermore, the pressure hemostatic block 302 is equipped with a pressure sensor, which can sense the hemostatic pressure of the radial artery in real time and transmit the signal to the computer via electrical signal, so that medical staff can clearly understand the patient's specific condition.

[0043] In this embodiment, since the diameter of the threaded positioning rod 203 is larger than the diameter of the hole in the positioning plate 206, the threaded positioning rod 203 is limited when one side moves to the outer surface of the positioning plate 206. This prevents the hollow slide tooth ring 204 from rotating excessively, causing the hollow slide rod frame 304 to descend too far and applying excessive pressure to the patient's radial artery, thus avoiding discomfort to the patient. Figure 7 As shown, the hollow slide bar 205 has two transverse tracks on its outer side, and the diameter of the hollow slide bar 205 is smaller than the opening of the positioning plate 206. Therefore, when the hollow slide bar 205 moves left and right with the threaded positioning rod 203, the transverse tracks of the hollow slide bar 205 (such as...) Figure 9 As shown, the hollow grooved gear ring 204 slides along the inside of the hollow grooved gear ring 204, so that the hollow grooved gear ring 204 is not affected by the sliding of the hollow grooved rod 205 along the inside of the hollow grooved gear ring 204 and rotates normally with the hollow grooved rod 205. The hollow grooved rod 205 not only serves as a driving component for adjusting the up and down movement of the hollow slide rod frame 304, but also as an auxiliary positioning component for positioning the rotational position of the hollow grooved gear ring 204.

[0044] like Figure 1 , Figure 10 and Figure 11As shown, the outer side of the annular hollow frame 301 has multiple vertical sliding grooves 306. An arc-shaped groove block 310 is rotatably installed inside the annular hollow frame 301. The arc-shaped groove block 310 is fixedly installed at the bottom of the endotracheal transfer rod 309. A bidirectional positioning rod 307 is fixedly installed between the arc-shaped groove block 310 and the vertical sliding grooves 306. A movable push block 308 is fixedly installed on the outer side of the bidirectional positioning rod 307. The movable push block 308 is slidably installed on the outer wall of the annular hollow frame 301. An airbag hemostatic block 303 is fixedly installed on one side of the movable push block 308 that passes through the annular hollow frame 301. The endotracheal transfer rod 309 is rotatably installed inside the hollow sliding frame 304. An inflation tube is inserted into the endotracheal transfer rod 309. The airbag hemostatic block 303 is connected to the inflation tube. During use, the patient's wrist is slightly rotated... Movement can cause the instrument to shift, and if the shift is greater than 5mm, the pressure point will deviate from the puncture point, causing bleeding that is difficult to treat. The balloon hemostatic block 303 is tightly attached to the outside of the pressure hemostatic block 302 in normal condition, providing synchronous positioning and pressure around the radial artery. It should be noted that the inflation tube inside the hollow slide bar frame 304 is not shown in the diagram. Its function is to transmit airflow to the balloon hemostatic block 303. The inflation tube is located inside the annular hollow frame 301 and has multiple shunt tubes that are flexible. When the airflow is transmitted to the balloon hemostatic block 303 through the shunt tubes, the bottom of the balloon hemostatic block 303 is arc-shaped and hook-shaped. After the balloon hemostatic block 303 is fully inflated, it expands and wraps around the radial artery, further reducing the interference of the pressure hemostatic block 302 and the radial artery contact position when the patient's arm moves. When it is necessary to clean the area around the radial artery or when the patient moves, medical staff first use the inflation tube to remove the airflow from the airbag hemostatic block 303. At this time, the endotracheal transfer rod 309 is manually rotated along the hollow slide bar frame 304. The endotracheal transfer rod 309 drives the arc-shaped groove block 310 to rotate clockwise. The top of the bidirectional positioning rod 307 is slidably installed in the arc-shaped track of the arc-shaped groove block 310, and the bottom of the bidirectional positioning rod 307 is slidably installed inside the vertical slide groove 306. Since the annular hollow frame 301 is fixed, the arc-shaped track of the arc-shaped groove block 310 guides the movement. The pusher 308 moves outward along the vertical groove 306. At this time, the pusher 308 moves the balloon hemostasis block 303 outward, exposing the periphery of the radial artery to the air. As the air in the balloon hemostasis block 303 is removed, the balloon hemostasis block 303 is in a contracted state. Medical staff can use a sterile cotton swab to clean the skin of the patient in this area by passing it between the balloon hemostasis block 303 and the annular hollow frame 301. At the same time, the sterile cotton swab can also clean the bottom of the balloon hemostasis block 303, thereby ensuring a safer environment around the radial artery and improving the safety of the radial artery when applying pressure for hemostasis.

[0045] It should be noted that an auxiliary pressure sensor is fixedly installed inside the airbag hemostatic block 303. By sensing the pressure around the radial artery in real time, it is possible to further understand whether the radial artery and the pressure hemostatic block 302 are misaligned when the patient's arm moves, thus improving safety.

[0046] like Figures 1-5 As shown, the arm clamping assembly 4 includes two rotating rods 403 rotatably mounted on both sides of the positioning plate 101. An arc-shaped clamping block 401 is fixedly mounted on the outer side of the rotating rod 403, and a clamping handle 402 is fixedly mounted on the top of the arc-shaped clamping block 401. A spring 408 is fixedly mounted between the arc-shaped clamping block 401 and the positioning plate 101. A filled airbag is fixedly mounted on the inner wall of the arc-shaped clamping block 401 through an opening. Two sets of hollow triangular positioning blocks 102 are fixedly mounted on both sides of the positioning plate 101, and the rotating rods 403 pass through the hollow triangular positioning blocks 102. A limit ring 405 is fixedly installed on one side of the block 102. A slotted clamping rod 404 is fixedly installed on one side of the hollow triangular positioning block 102 through the rotating rod 403. Hollow slide rails are provided on the upper and lower sides of the slotted clamping rod 404. A multi-toothed ring sleeve 406 is slidably installed on the outer side of the slotted clamping rod 404 through the hollow slide rails. A multi-toothed hole 407 is provided on the outer side of the hollow triangular positioning block 102. The multi-toothed hole 407 is adapted to the multi-toothed ring sleeve 406. The positioning base assembly 5 includes two sets of telescopic blocks 501 hinged to the bottom of the arc-shaped clamping block 401. When medical staff position and clamp the radial artery around the patient, they first grasp the clamping handle 402. The clamping handle 402 is bent inward along the positioning plate 101, creating a large space between the two arc-shaped clamping blocks 401. Then, the patient's arm is passed between the two arc-shaped clamping blocks 401, with the side of the arm away from the radial artery resting against the telescopic block 501. Simultaneously, the elastic force of the spring 408 causes the arc-shaped clamping blocks 401 to avoid the patient's ulnar artery and adhere to the patient's arm skin surface. Figure 1 As shown, the arc-shaped clamping block 401 has an opening on its surface, which can be used to install an airbag. The airbag replaces the arc-shaped clamping block 401 and fits against the patient's arm skin, which can reduce the patient's discomfort. Furthermore, due to the elastic force of the spring 408, the arc-shaped clamping block 401 can be stably clamped on the patient's arm, which improves the stability of the clamping.

[0047] like Figures 4 to 6As shown, a mating slot block 502 is slidably installed between the two sets of telescopic blocks 501. A side positioning block 503 is fixedly installed on the top of the telescopic block 501. This makes it impossible to install the device appropriately according to the different wrist sizes of different patients, requiring the replacement of instruments of different sizes, increasing costs. After the arc-shaped clamping block 401 clamps the patient's arm skin, the two telescopic blocks 501 move with the arc-shaped clamping block 401, and the two telescopic blocks 501 extend and retract along the mating slot block 502, causing the side positioning blocks 503 to rest against the bottom of both sides of the arm, forming a triangular clamping area with the pressure hemostatic block 302, further improving the stability of the instrument's radial artery positioning. After the arc-shaped clamping block 401 is positioned, the medical staff slides the multi-toothed ring sleeve 406 along the rotating rod 403. The multi-toothed ring sleeve 406 is inserted into the multi-toothed hole 407. Because the insert block on the inner wall of the multi-toothed ring sleeve 406 is inserted into the hole of the empty slot clamping rod 404, the multi-toothed ring sleeve 406 and the empty slot clamping rod 404 are properly positioned. The slotted clamping rod 404 rotates synchronously. As the multi-toothed ring sleeve 406 engages in the multi-toothed hole 407, the rotating rod 403 and the empty slotted clamping rod 404 cannot rotate. The arc-shaped clamping block 401 is limited and cannot continue to move. At this time, the telescopic block 501 cannot deviate, thus stabilizing the telescopic block 501. The two side positioning blocks 503 and the pressure hemostatic block 302 clamp the patient's arm, so that the patient's skin does not need to contact too much clamping material, improving the patient's comfort. At this time, medical staff can inflate the airbag of the arc-shaped clamping block 401, so that the airbag fits and clamps the patient's arm skin, further improving the patient's comfort.

[0048] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
