Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a pressure-applying radial artery compression hemostasis device. Background Art

[0002] The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery is about 21.2 cm long and has an outer diameter of about 0.3 cm at the origin. After the brachial artery is separated, it runs outward and downward, first passing between the brachioradialis and pronator teres, then between the radial flexor carpi and the brachioradialis, and then to the lower end of the radius, obliquely passing through the deep surface of the tendons of the abductor pollicis longus and the extensor pollicis brevis to the back of the hand to enter the anatomical nasopharyngeal fossa, and then passing through the first metacarpal space to enter the deep part of the palm. After the main thumb artery is separated, it anastomoses with the deep palmar branch of the ulnar artery to form a deep palmar arch. The radial artery is shallow between the lower end of the radius and the radial flexor carpi tendon, which is an ideal site for palpation and puncture. After the radial artery puncture surgery, the puncture site needs to be compressed to stop bleeding.

[0003] At present, manual hemostasis is routinely used at the puncture site after surgery. Compared with venous puncture, radial artery puncture requires much longer compression hemostasis time, generally more than 15 minutes. Conventional compression hemostasis methods include nurses pressing and hemostasis with hands, wrapping with gauze, and fixing with elastic bandages. These methods are cumbersome, time-consuming, and labor-intensive. In addition, the tightness is difficult to control, which can easily cause blood reflux. Therefore, there is room for improvement and development in response to the above problems. Summary of the invention

[0004] The present invention provides a pressure-type radial artery compression hemostasis device, which can effectively compress and stop bleeding on the radial artery of a patient without manual compression by medical staff, thereby improving the work efficiency of medical staff and effectively avoiding the problem of blood reflux caused by insufficient pressure at the puncture site. The specific implementation methods are as follows: A pressure-type radial artery compression hemostasis device comprises a frame with a window, a hemostatic bandage, and a reel module, an advance and retreat belt module, a cutting module, and a belt guide slot module sequentially arranged on the frame, wherein the belt guide slot module is arranged corresponding to the window, the hemostatic bandage is wound on the reel module, and the reel module, the advance and retreat belt module, the cutting module, and the belt guide slot module are sequentially arranged on the frame along the conveying direction of the hemostatic bandage; A buffer module is arranged at the window position corresponding to the frame, and the buffer module can be movably arranged on the frame. When the hemostatic bandage is withdrawn from the discharge position of the belt guide groove module under the action of the advance and retreat belt module, the buffer module provides a buffering force for the hemostatic bandage.

[0005] As a further solution of the present invention, the buffer module includes a sliding seat that can move relative to the frame, an auxiliary wheel, and an elastic member. The axis of the auxiliary wheel is perpendicular to the transmission direction of the hemostatic bandage and is movably arranged. The auxiliary wheel can move relative to the window area, and both ends of the elastic member are respectively abutted against the sliding seat and the auxiliary wheel.

The connecting rod is axially sleeved on the sleeve rod. The elastic member is sleeved on the connecting rod and its two ends are respectively abutted on the sliding seat and the sleeve rod.

[0007] As a further solution of the present invention, a driving unit for driving the sliding seat to move is provided on the frame, and the driving unit includes a driving motor and a screw connected to the driving motor. The screw is rotatably provided on the frame, and the sliding seat is rotatably connected to the screw.

[0008] As a further solution of the present invention, two groups of buffer modules are provided, and the two groups of buffer modules are symmetrically arranged along the central axis of the frame.

[0009] As a further solution of the present invention, the cutting module includes a cam group, a top knife component, and a tool arranged corresponding to the top knife component. The cam group is connected to the top knife component, and the cam group is used to drive the top knife component to move.

[0010] As a further solution of the present invention, the frame is provided with a distance measuring sensor corresponding to the cutting module, and at least two distance measuring sensors are provided.

[0011] As a further solution of the present invention, the front and back sides of the hemostatic bandage are provided with mating fleece surfaces and hook surfaces, the hemostatic bandage is conveyed through the discharge position of the belt guide slot module, and the fleece surfaces and hook surfaces are tensioned and bonded under the action of the advance and retreat belt module.

[0012] As a further solution of the present invention, the hemostatic bandage has an inflation cavity and an air inlet, wherein the air inlet is used to realize gas exchange between the inflation cavity and the outside. Gas enters the inflation cavity through the air inlet, causing the hemostatic bandage to expand to achieve compression of the radial artery.

[0013] As a further solution of the present invention, the frame is provided with a guide plate corresponding to the tape guide slot module, and the guide plate has a guide surface, and the guide surface is inclined and abuts against the hemostatic bandage.

[0014] Due to the adoption of the above technical solution, the beneficial technical effects of the present invention are: The present invention can effectively compress and stop bleeding on the radial artery of the patient without manual pressing by medical staff, thereby improving the work efficiency of medical staff and effectively avoiding the problem of blood reflux caused by insufficient pressure at the puncture site.

In addition, gas is introduced into the hemostatic bandage to expand it, so as to adjust the pressure of the hemostatic bandage on the puncture site. The hemostatic bandage has a significant compression hemostasis effect. The present invention is provided with a buffer module, and the advance and retreat belt module drives the hemostatic bandage to retreat and bandage the patient, and the buffer module blocks to provide a buffer force, so as to prevent the hemostatic bandage from directly acting on the puncture site of the patient and causing harm to the patient, thereby improving safety.

Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0019] Embodiment 1, combination Figures 1 to 9 As shown, the present embodiment provides a pressure-type radial artery compression hemostasis device, comprising a frame 1 with a window 13, a hemostatic bandage 3, and a reel module 2, an advance and retreat belt module 6, a cutting module 10, and a belt guide slot module 5 which are sequentially arranged on the frame 1, wherein the belt guide slot module 5 is arranged corresponding to the window 13, the hemostatic bandage 3 is wound around the reel module 2, the reel module 2, the advance and retreat belt module 6, the cutting module 10, and the belt guide slot module 5 are sequentially arranged on the frame 1 along the conveying direction of the hemostatic bandage 3; a buffer module 8 is arranged at a position of the frame 1 corresponding to the window 13, and the buffer module 8 can be movably arranged on the frame 1, and when the hemostatic bandage 3 is withdrawn from the discharge position of the belt guide slot module 5 under the action of the advance and retreat belt module 6, a buffer force is provided to the hemostatic bandage 3 through the buffer module 8.

[0020] For example, refer to Figure 1As shown, the compression hemostasis device also includes a control system, which is used to control the operation of each driving device. The frame 1 has an operating table 11 for placing the radial artery puncture site of the patient. The operating table 11 is a plane and can support the patient's forearm. A gantry is vertically arranged on the top of the frame 1, and a window 13 is arranged on the gantry. The window 13 can be inserted into the patient's forearm, and its shape can be a square structure. Support pads 12 are arranged in front and behind the operating table 11 corresponding to the window 13. The support pads 12 can be made of silicone. The patient's forearm is placed on the support pad 12 for support, so as to improve the patient's comfort. The shape of the window 13 can also be designed to be other shapes according to actual conditions.

[0021] Specifically, the reel module 2 is disposed at the side of the frame 1, and is used to wind the hemostatic bandage 3. The reel module 2 includes a reel and a brake (not shown) connected to the reel. The hemostatic bandage 3 is wound on the reel 22. The brake can stop the reel from rotating when the tape feeding stops, so as to avoid the hemostatic bandage 3 from being entangled due to excessive tape feeding due to inertia.

[0022] Specifically, refer to Figure 2 As shown, the frame 1 is located at the bottom of the operating table 11 and is formed with a receiving chamber 14. A delivery member 4 is rotatably arranged in the receiving chamber 14. The delivery member 4 is used to deliver the hemostatic bandage 3 from the reel to the advance and retreat belt module 6. The delivery member 4 includes a motor (not shown in the figure), a main delivery wheel 41 and a slave delivery wheel 42. The motor drives the main delivery wheel 41 to rotate, and the main delivery wheel 41 and the slave delivery wheel 42 are tightly arranged. The hemostatic bandage 3 is delivered to the advance and retreat belt module 6 under the action of the main delivery wheel 41 and the slave delivery wheel 42.

[0023] Specifically, refer to Figure 6 As shown, the belt advance and retreat module 6 includes a belt advance mechanism and a belt retreat mechanism. The belt advance mechanism includes a motor, a belt advance driving wheel 61 and a belt advance driven wheel 62. The motor drives the belt advance driving wheel 61 to rotate, and the belt advance driving wheel 61 and the belt advance driven wheel 62 are pressed together. The belt retreat mechanism includes a motor, a belt retreat driving wheel 65 and a belt retreat driven wheel 66. The motor drives the belt retreat driving wheel 65 to rotate, and the belt retreat driven wheel 66 and the belt retreat driving wheel 65 are pressed together. A tensioning mechanism is arranged between the belt advance mechanism and the belt retreat mechanism. The tensioning mechanism includes a motor, a tensioning driving wheel 63 and a tensioning driven wheel 64. The motor drives the tensioning driving wheel 63 to rotate, and the tensioning driving wheel 63 and the tensioning driven wheel 64 are pressed together. A certain angle is formed between the tensioning mechanism and the belt advance driving wheel 61 and the belt advance driven wheel 62 to ensure the contact pressure between the hemostatic bandage 3 and the wheel body, thereby ensuring the efficiency of power transmission and normal operation. Avoid the hemostatic bandage 3 from slipping.

[0024] Exemplarily, the advance and retreat belt module 6 also includes an auxiliary mechanism, which includes a motor, an auxiliary driving wheel 67 and an auxiliary driven wheel 68. The motor drives the auxiliary driving wheel 67 to rotate, and the auxiliary driving wheel 67 and the auxiliary driven wheel 68 are pressed together. The auxiliary mechanism can reduce the distance between the advance and retreat belt module 6 and the delivery component 4 to ensure the normal delivery of the hemostatic bandage 3.

[0025] In specific application, the hemostatic bandage 3 passes between the retracting driven wheel 66 and the retracting driving wheel 65, and then enters between the feeding driving wheel 61 and the feeding driven wheel 62. When feeding, the feeding driving wheel 61 rotates counterclockwise to feed the hemostatic bandage 3 forward. After the feeding is completed, the feeding driving wheel 61 rotates clockwise to retract the excess hemostatic bandage 3. When the hemostatic bandage 3 is close to the patient's forearm, the feeding driving wheel 61 can no longer drive the hemostatic bandage 3 to move, and the feeding driven wheel 62 stops rotating. At the same time, the retracting driving wheel 65 starts to rotate clockwise at a certain angle. The rotation of the retracting driving wheel 65 retracts the excess hemostatic bandage 3, so that the hemostatic bandage 3 is close to the patient's forearm, completing the bandaging operation. Finally, before the retracting driving wheel 65 rotates, adjust the retracting driven wheel 66 to press the retracting driving wheel 65 tightly to clamp the hemostatic bandage 3.

[0026] Specifically, the structure of the tape guide slot module 5 matches the shape of the window 13. The tape guide slot module 5 includes a tape guide slot 16, which includes a feed position and a discharge position, both of which are arranged on the operating table 11, and the feed position and the discharge position are arranged opposite to each other. After the hemostatic bandage 3 enters the tape guide slot 16 from the feed position, it goes around the tape guide slot 16 once, and then returns from the discharge position.

[0027] Specifically, in order to separate the wrapped hemostatic bandage 3 from the withdrawn hemostatic bandage 3, a cutting module 10 is provided on the frame 1, which is used to cut the hemostatic bandage 3 and drive the opening and closing of the belt guide groove 16. The cutting module 10 includes a cam group, a top knife component, and a tool corresponding to the top knife component. The cam group is connected to the top knife component, and the cam group is used to drive the top knife component to move. The tool is arranged in parallel with the top knife component. When the hemostatic bandage 3 is withdrawn, the tool can cut the hemostatic bandage 3, and the wrapped patient's forearm can be pulled out from the window 13.

[0028] Specifically, refer to Figure 7As shown, in order to enable the hemostatic bandage 3 to bandage the puncture site of the patient, the front and back sides of the hemostatic bandage 3 are provided with a fleece surface 34 and a hook surface 33 that cooperate with each other. The hemostatic bandage 3 is conveyed through the discharge position of the belt guide slot module 5, and the fleece surface 34 and the hook surface 33 are bonded after being tensioned under the action of the advance and retreat belt module 6. Exemplarily, there are multiple fleece surfaces 34 and hook surfaces 33, multiple fleece surfaces 34 are arranged at intervals along the front side of the hemostatic bandage 3, and multiple hook surfaces 33 are arranged at intervals along the back side of the hemostatic bandage 3. The distance from the starting point of each fleece surface 34 to the end point of the hook surface 33 is set to 35 cm, and the distance from the fleece surface 34 to the hook surface 33 can be selected according to actual conditions.

[0029] Specifically, since the arm circumference of the patient's forearm is different, the length of the hemostatic bandage 3 used is different. In order to avoid the misalignment of the hook surface 33 and the hair surface 34 when the hemostatic bandage 3 is bandaged on the patient's forearm again, the frame 1 is provided with a distance sensor 7 corresponding to the cutting module 10. The distance sensors 7 are at least two, and the two distance sensors 7 are arranged side by side along the conveying direction of the hemostatic bandage 3. The distance sensors 7 are used to detect the feeding amount and the retracting amount of the hemostatic bandage 3. The distance sensor 7 includes a first distance sensor and a second distance sensor. The first distance sensor and the second distance sensor are respectively arranged corresponding to the cutting module 10. The first distance sensor detects the feeding amount of the hemostatic bandage 3, and the second distance sensor detects the retracting amount of the hemostatic bandage 3.

[0030] In specific application, when feeding the belt, the belt feed driving wheel 61 rotates counterclockwise to feed the hemostatic bandage 3 forward, the first distance measuring sensor detects that the feeding length of the hemostatic bandage 3 is 35 cm, the first distance measuring sensor sends a signal and controls the advance and retreat belt module 6 to stop feeding the belt, after the feeding is completed, the belt feed driving wheel 61 rotates clockwise to retract the excess hemostatic bandage 3, the cutting module 10 cuts off the hemostatic bandage 3, the second distance measuring sensor detects that the retreat length of the hemostatic bandage 3 is 5 cm, the second distance measuring sensor sends a signal and controls the advance and retreat belt module 6 to feed the belt 5 cm in the direction of the belt guide groove 16, and the cutting module 10 performs the cutting operation again, thereby ensuring that the hemostatic bandage 3 is used 35 cm each time, thereby effectively avoiding the misalignment of the hook surface 33 and the fur surface 34.

[0031] Specifically, refer to Figure 3As shown, the buffer module 8 includes a sliding seat 84 that can move relative to the frame 1, an auxiliary wheel 83, and an elastic member. The axis of the auxiliary wheel 83 is perpendicular to the conveying direction of the hemostatic bandage 3 and is movably arranged. The auxiliary wheel 83 can move relative to the window 13 area, and the two ends of the elastic member are respectively abutted on the sliding seat 84 and the auxiliary wheel 83. Before the advance and retreat belt module 6 drives the hemostatic bandage 3 to retract and the hemostatic bandage 3 is pressed against the patient's forearm, the annular structure formed by the hemostatic bandage 3 falls on the auxiliary wheel 83, and the auxiliary wheel 83 is used to block the hemostatic bandage 3 to provide a buffering force, thereby effectively preventing the hemostatic bandage 3 from directly acting on the patient's puncture site and causing harm to the patient. When the hemostatic bandage 3 is close to the patient's forearm, the auxiliary wheel 83 moves and is pulled out of the annular structure, so that the hemostatic bandage 3 is pressed against the patient's forearm, thereby achieving the bandaging operation of the hemostatic bandage 3.

[0032] For example, refer to Figure 4 As shown, a sleeve rod 87 and a connecting rod 85 are connected between the auxiliary wheel 83 and the sliding seat 84 in sequence, the connecting rod 85 is axially sleeved on the sleeve rod 87, and the elastic member is sleeved on the connecting rod 85 and the two ends are respectively abutted on the sliding seat 84 and the sleeve rod 87. A support member 89 is provided at the bottom of the sleeve rod 87, and the auxiliary wheel 83 is movably provided on the support member 89. The support member 89 is provided with a first cylinder 88 for driving the auxiliary wheel 83 to move, and the first cylinder 88 can drive the auxiliary wheel 83 to move closer to or away from the hemostatic bandage 3. Preferably, the elastic member is set as a buffer spring 86, and the two ends of the buffer spring 86 are respectively connected to the sliding seat 84 and the sleeve rod 87. The elastic deformation of the buffer spring 86 can drive the auxiliary wheel 83 to move toward the patient's forearm, and can also control the moving distance of the auxiliary wheel 83 to avoid the auxiliary wheel 83 from moving too low, causing the hemostatic bandage 3 to directly act on the patient's puncture site and cause harm to the patient.

[0033] Exemplarily, a driving unit for driving the sliding seat 84 to move is provided on the frame 1, and the driving unit includes a driving motor 81 and a screw 82 connected to the driving motor 81. The screw 82 is rotatably provided on the frame 1, and the sliding seat 84 is rotatably connected to the screw 82. A fixing seat 17 is provided at the end of the frame 1 corresponding to the screw 82, and the screw 82 is rotatably connected to the fixing seat 17. The driving motor 81 drives the screw 82 to rotate, driving the auxiliary wheel 83 on the sliding seat 84 to approach the patient's forearm. The advance and retreat belt module 6 drives the hemostatic bandage 3 to retreat. Before the hemostatic bandage 3 is close to the patient's forearm, the annular structure formed by the hemostatic bandage 3 falls on the auxiliary wheel 83. The auxiliary wheel 83 is used to block the hemostatic bandage 3 to provide a buffer force, thereby effectively preventing the hemostatic bandage 3 from directly acting on the patient's puncture site and causing harm to the patient. The first cylinder 88 starts and drives the auxiliary wheel 83 away from the hemostatic bandage 3, so that the hemostatic bandage 3 is close to the patient's forearm, thereby realizing the bandaging operation of the patient's radial artery puncture site.

[0034] Preferably, two groups of buffer modules 8 are provided, and the two groups of buffer modules 8 are symmetrically arranged along the central axis of the frame 1. The screw 82 is a bidirectional threaded rod, and the two groups of buffer modules 8 are symmetrically arranged at both ends of the bidirectional threaded rod. The drive motor 81 drives the screw 82 to rotate, driving the two groups of buffer modules 8 to approach the center position of the frame 1. Before the hemostatic bandage 3 is wrapped around the patient's forearm, the buffer modules 8 located on both sides of the patient's forearm simultaneously block the hemostatic bandage 3, thereby improving the buffering effect of the hemostatic bandage 3.

[0035] Specifically, in order to prevent the rough surface 34 and the hook surface 33 of the hemostatic bandage 3 from sticking together, a guide member 9 is provided on the frame 1. The guide member 9 corresponds to the guide member including a guide plate 92 and a second cylinder 91. The second cylinder 91 can drive the guide plate 92 to move. The guide plate 92 corresponds to the tape guide slot module 5 and is arranged on the frame 1. The guide plate 92 has a guide surface, which is inclined and abuts against the hemostatic bandage 3, effectively preventing the rough surface 34 and the hook surface 33 of the hemostatic bandage 3 from sticking together.

[0036] Specifically, refer to Figure 7 As shown, in order to further improve the compression and hemostasis effect of the hemostatic bandage 3, the hemostatic bandage 3 has an air filling cavity 32 and an air inlet 36. The air inlet 36 is used to realize the exchange of air between the air filling cavity 32 and the outside gas. The gas enters the air filling cavity 32 through the air inlet 36, so that the hemostatic bandage 3 expands to achieve compression of the radial artery. A check valve 37 is provided on the air inlet 36 to prevent the gas flowing into the air filling cavity 32 from flowing back. The hemostatic bandage 3 is a medical elastic bandage. The hemostatic bandage 3 has an air filling cavity 32 that can accommodate gas. When it is necessary to stop bleeding from the wound of the injured person, the air inlet 36 is connected to an external inflation device, and the gas enters the air filling cavity 32 through the air inlet 36, so that the hemostatic bandage 3 expands to compress the patient's radial artery and stop bleeding. The operation is simple.

[0037] For example, refer to Figure 8 As shown, a connection portion 38 is provided on the hemostatic bandage 3 at a position corresponding to the air inlet 36, and a plugging cap 31 is connected to the connection portion 38. The plugging cap 31 and the connection portion 38 can be threadedly connected. The surface of the hemostatic bandage 3 has a compression portion 35, which is close to the patient's forearm. The compression portion 35 contains therapeutic drugs to perform drug treatment on the radial artery puncture site of the patient. The hemostatic bandage 3 is also provided with an exhaust port (not shown in the figure) for gas outflow. When gas needs to be discharged, the exhaust port can be opened.

[0038] Exemplarily, in order to enable the frame 1 to move, a universal wheel 15 is provided at the bottom of the frame 1, and a material receiving drawer 18 and a storage drawer 19 are also provided on the frame 1. The material receiving drawer 18 is connected to the accommodating chamber 14. The cut hemostatic bandages 3 are collected by the material receiving drawer 18 for centralized processing, thereby avoiding the cut hemostatic bandages 3 from being piled up in a disorderly manner in the frame 1. The storage drawer 19 can be used to place medical supplies to increase the storage space.

[0039] The working principle of the present invention is that the patient's forearm is extended from the window 13 and placed on the support pad 12, and the buffer module 8 is adjusted according to the circumference of the patient's forearm. When bandaging, the hemostatic bandage 3 passes between the unwinding driven wheel 66 and the unwinding active wheel 65, and then enters between the feeding active wheel 61 and the feeding driven wheel 62. When the belt is fed, the belt feed driving wheel 61 rotates counterclockwise to feed the hemostatic bandage 3 forward. After the belt feeding is completed, the belt feed driving wheel 61 rotates clockwise to return the excess hemostatic bandage 3. The annular structure formed by the hemostatic bandage 3 falls onto the auxiliary wheel 83. The auxiliary wheel 83 is used to block the hemostatic bandage 3 to provide a buffer force, thereby effectively preventing the hemostatic bandage 3 from directly acting on the patient's puncture site and causing harm to the patient. The first cylinder 88 starts and drives the auxiliary wheel 83 away from the hemostatic bandage 3, so that the hemostatic bandage 3 is close to the patient's forearm. At the same time, the cutting module 10 cuts off the hemostatic bandage 3, thereby achieving compression hemostasis at the patient's radial artery puncture site. After the bandage is completed, the patient's forearm can be withdrawn from the window 13 position, which effectively improves the work efficiency of medical staff and has a significant compression hemostasis effect.

[0040] Many other changes and modifications may be made without departing from the concept and scope of the present invention.It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
