Description

Technical Field

[0001] The invention relates to the field of cardiology nursing, and more specifically to a radial artery compressor for cardiology nursing. Background Art

[0002] Because the radial artery approach has the advantages of less trauma, fewer intraoperative complications and faster postoperative recovery during interventional treatment, radial artery puncture intervention has become the most commonly used interventional treatment method for cardiovascular diseases such as coronary heart disease.

[0003] The common radial artery compressor is a spiral compression type arterial compression hemostat, which consists of a fixed strap, a dial, a spiral handle and a pressure plate. It is an external wearable hemostatic device. When used, the radial artery compressor is first fixed to the wrist with a strap, and then the spiral handle is rotated so that the pressure plate applies pressure directly downward on the puncture point of the radial artery from outside the body, ultimately achieving the purpose of hemostasis.

[0004] However, in the actual use of the radial artery compressor, due to long-term compression, the radial artery compressor may cause nerve and blood vessel damage, thrombosis, pain and discomfort, etc. In order to alleviate or avoid the above problems, the common treatment method in the prior art is: according to different patient conditions, the compressor is intermittently released, for example, the upper limb compression is released once every half an hour, and the lower limb compression is released once every hour or so. The compressor is relaxed for 1-2 minutes, and finger pressure can be used to stop bleeding during this process.

[0005] Conventional radial artery compressors in the prior art need to repeatedly rotate the handle to apply or release pressure on the bleeding point in order to complete the intermittent compression operation in accordance with the above requirements. In the process, the radial artery compressor needs to be moved away from the bleeding point and pressed with finger pressure to stop bleeding to achieve relaxation, thereby achieving the effect of intermittent relaxation and compression. However, the entire operation process has many repetitive steps, is relatively cumbersome, and has low efficiency. In addition, the operation difficulty and the requirements for medical personnel are high, and it is not suitable for clinical promotion. Summary of the invention

[0050] like Figures 1 to 9 As shown, an embodiment of the present invention provides a radial artery compressor for cardiology nursing, comprising an upper wrist piece 1 and a lower wrist piece 2 arranged in parallel, and the upper wrist piece 1 and the lower wrist piece 2 are arranged in an arc shape on opposite sides; buckles 3 are symmetrically arranged on both sides of the upper wrist piece 1 and the lower wrist piece 2, and a locking belt 4 is wound between the buckles 3, and one end of the locking belt 4 is provided with a Velcro 5 that cooperates with each other;

[0051] The upper wrist piece 1 is also provided with a switching component 6 for switching the compression state; the switching component 6 includes a support frame 10 fixedly mounted on the upper surface of the upper wrist piece 1, a No. 1 motor 11 is fixedly mounted on the upper end of the support frame 10, and the output end of the No. 1 motor 11 passes through the support frame 10 and is fixedly connected to a switching shaft 12, and the lower end of the switching shaft 12 is fixedly connected to a switching frame 13; a compression component for compressing the radial artery is movably mounted at one end inside the switching frame 13; an acupressure component 20 for intermittently relaxing compression is provided at the other end inside the switching frame 13.

[0052] The upper wrist piece 1 and the lower wrist piece 2 are provided with retaining components 9 at two ends of the opposite side to each other, which provide a switching space for the switching component 6 .

[0053] A control panel 7 is disposed on one side of the upper surface of the upper wrist piece 1 , and a storage battery 8 is disposed on the other side of the upper surface of the upper wrist piece 1 .

[0054] When in use, first put the wrist between the upper wrist piece 1 and the lower wrist piece 2 to ensure that the bleeding position of the radial artery is at the center of the upper wrist piece 1 and the lower wrist piece 2, and then pull the end of the lock belt 4 to make the upper wrist piece 1 and the lower wrist piece 2 close to each other to lock the wrist. After locking, use the Velcro 5 to stick the lock belt 4 around the lock buckle 3 to fix the wrist, and then use the control panel 7 to control the switching component 6 to work, that is, the No. 1 motor 11 works, drives the switching shaft 12 to rotate, and then drives the switching frame 13 to rotate, and the compression component and the acupressure component 20 They are respectively arranged at the two ends inside the switching frame 13. When the switching frame 13 rotates, the positions of the compression component and the acupressure component 20 can be switched. According to this operation, the compression component is first rotated to the corresponding bleeding position, and the compression component is pressed down to press against the bleeding point of the radial artery for compression. After a period of compression (it should be noted here that the compression time is based on the patient's bleeding situation. Generally, the upper limbs are compressed for half an hour and then released, and the lower limbs are compressed for about an hour and then released), the switching component 6 is used to switch the acupressure component 20 to the working position, and the acupressure is released.

[0055] The present invention provides a switching component 6, which can conveniently exchange the positions of the compression component and the finger pressure component 20, so that the bleeding point of the radial artery can be intermittently compressed and released, thereby ensuring that the common problems of the existing radial artery compressor, such as nerve and blood vessel damage, thrombosis, pain, etc. caused by long-term compression use, are alleviated. In addition, the present invention realizes automatic switching during the switching process, and there is no need to manually rotate the handle repeatedly to pressurize or relieve the bleeding point. The existing finger pressure process is also replaced by the finger pressure component 20 in the present invention, which further improves the degree of automation of the device, further reduces the steps of compression hemostasis, improves the hemostasis efficiency, reduces the difficulty of using the compressor, and reduces the requirements for medical personnel, which is more suitable for clinical promotion.

[0056] like Figure 3 and Figure 4 As shown, a driving component is also provided in the middle position inside the switching frame 13, which is used to drive the compression component and the acupressure component 20 to work; the driving component includes a No. 2 motor 21 fixedly installed at the bottom of the switching frame 13, and the output end of the No. 2 motor 21 extends through the inside of the switching frame 13 and rotatably installs an intermediate gear 18, and the intermediate gear 18 is respectively engaged with the compression component and the acupressure component 20, and drives the compression component and the acupressure component 20 to work.

[0057] like Figures 1 to 4As shown, the compression assembly includes a rotating adjustment gear 15 rotatably installed at one end inside the switching frame 13, and the rotating adjustment gear 15 is meshed with one side of the intermediate gear 18; the rotating adjustment gear 15 is internally connected with a threaded rod 16 through a thread, the upper end of the threaded rod 16 passes through the switching frame 13 and is fixedly connected to the limit member 14, and the lower end of the threaded rod 16 passes through the switching frame 13 and is fixedly connected to the compression plate 17.

[0058] When the compression assembly is working, the middle gear 18 is driven to rotate by controlling the operation of the No. 2 motor 21, and the rotating adjustment gear 15 is meshed with one side of the middle gear 18. When the middle gear 18 rotates, it will drive the rotating adjustment gear 15 to rotate inside the switching frame 13. The rotating adjustment gear 15 is internally connected with a threaded rod 16 through a thread. When the rotating adjustment gear 15 rotates, the threaded action of the rotating adjustment gear 15 and the threaded rod 16 will cause the threaded rod 16 to drive the compression plate 17 to rise or fall.

[0059] like Figure 5 to Figure 6 As shown, the acupressure assembly 20 includes a driven gear 19 rotatably mounted at the other end of the switching frame 13 and meshing with the other side of the intermediate gear 18; the bottom of the driven gear 19 passes through the switching frame 13 and is fixedly connected to the adjusting worm 201, and the lower surface of the switching frame 13 is symmetrically fixedly connected to two mounting frames 202 about the adjusting worm 201, and the middle positions of the two mounting frames 202 are rotatably mounted with adjusting worm wheels 204, and the two adjusting worm wheels 204 are meshed with the adjusting worm 201; one side of the two adjusting worm wheels 204 is fixedly connected to a No. 1 connecting rod 203, and one end of the two No. 1 connecting rods 203 is hinged to a No. 2 connecting rod 205, and one end of the two No. 2 connecting rods 205 is jointly hinged to an adjusting platform 206, and a kneading assembly 208 is movably provided inside the adjusting platform 206, and a acupressure head 207 is movably connected through the kneading assembly 208.

[0060] When the acupressure assembly 20 is working, the No. 2 motor 21 works, driving the intermediate gear 18 to rotate, and the driven gear 19 is meshed with the other side of the intermediate gear 18. When the intermediate gear 18 rotates, it drives the driven gear 19 to rotate, and the bottom of the driven gear 19 passes through the switching frame 13 and is fixedly connected to the adjusting worm 201, thereby driving the adjusting worm 201 to rotate. When the adjusting worm 201 rotates, the two adjusting worm wheels 204 meshed with the adjusting worm 201 rotate in the opposite direction, and drive the two No. 1 connecting rods 203 to synchronously adjust the center position of the worm wheel 204 to move upward or downward, and drive the adjusting platform 206 to rise or fall through the hinged No. 2 connecting rod 205, and the acupressure head 207 is movably connected to the adjusting platform 206. When the adjusting platform 206 rises or falls, it will synchronously drive the acupressure head 207 to rise or fall, so as to realize the acupressure or release of the radial artery compression point.

[0061] The present invention provides a finger pressure component 20 to simulate the pressing of the bleeding point with fingers in the prior art finger pressure method, and then cooperates with the compression components to switch with each other to achieve intermittent compression of the radial artery bleeding point, further improving the degree of automation of the device, and further reducing the steps of compression hemostasis, thereby improving the hemostasis efficiency. In addition, since medical staff do not need to perform finger compression, the workload of medical staff is reduced.

[0062] like Figures 6 to 8 As shown, the massage component 208 includes a rotating groove 2083 opened inside the adjustment platform 206, and the rotating groove 2083 is rotatably connected to a rotating ball 2084. The rotating ball 2084 is penetrated and fixedly connected with an L-shaped swing rod 2082 inside. The lower end of the L-shaped swing rod 2082 is fixedly connected to the finger pressure head 207, and the upper end of the L-shaped swing rod 2082 is fixedly connected to the adapter slide rod 2081.

[0063] like Fig. 9 As shown, a hemispherical rubber sleeve 210 is bonded to the outer side of the finger pressure head 207 , and a pressure sensor 209 is also provided between the finger pressure head 207 and the hemispherical rubber sleeve 210 .

[0064] like Figures 6 to 8 As shown, the adapting slide rod 2081 is slidably arranged inside the adjusting worm 201; the outer cylindrical surface of the adapting slide rod 2081 is annularly fixed with uniformly distributed limiting plates 2085, and the adjusting worm 201 has limiting grooves 2086 corresponding to the limiting plates 2085, and the adapting slide rod 2081 is slidably connected to the inside of the adjusting worm 201 through the limiting plates 2085 and the limiting grooves 2086.

[0065] When the kneading assembly 208 is working, the adjusting worm 201 rotates, and the adapting slide bar 2081 is driven to rotate through the limit groove 2086 and the limit plate 2085. The rotation of the adapting slide bar 2081 can drive the L-shaped swinging rod 2082 to rotate, and cooperate with the rotating groove 2083 and the rotating ball 2084 to realize the rotation of the finger pressure head 207 with the rotating ball 2084 as the center point. It should be noted here that the kneading assembly 208 and the finger pressure assembly 20 work synchronously. Since the operation of the finger pressure assembly 20 will drive the adjustment platform 206 to rise or fall, The finger pressing head 207 and the L-shaped swinging rod 2082 are driven to rise or fall by rotating the ball 2084. In the present invention, the setting of the limiting piece 2085 and the limiting groove 2086 is used to make the rotating ball 2084, the finger pressing head 207 and the L-shaped swinging rod 2082 cooperate with the rotation of the adjusting worm 201, and the adapting slide bar 2081 can also synchronously use the limiting piece 2085 and the limiting groove 2086 to rise or fall inside the adjusting worm 201 to cooperate with the rise or fall of the adjusting platform 206, thereby avoiding the motion interference between the mechanisms;

[0066] In addition, it should be noted that in the specific work, after the switching is completed (the acupressure component 20 is in the working position), the second motor 21 is first operated to drive the acupressure component 20 to work, so that the acupressure head 207 descends. During this descending process, the second motor 21 does not reciprocate and reverse, and the acupressure head 207 does not reciprocate. When the acupressure head 207 contacts the bleeding point and the pressure sensor 209 between the acupressure head 207 and the hemispherical rubber sleeve 210 detects that the pressure of the acupressure head 207 on the bleeding point reaches the minimum specified pressure requirement, the control panel 7 records this position as the highest point of the reciprocating motion of the acupressure head 207. As the acupressure head 207 continues to press down, the pressure sensor 209 detects that the pressure of the acupressure head 207 on the bleeding point reaches the maximum pressure requirement. The control panel 7 records this position as the lowest point of the reciprocating motion of the finger pressure head 207. After the finger pressure head 207 reaches the lowest point, the No. 2 motor 21 reverses to drive the finger pressure head 207 to rise, thereby reducing the pressure on the bleeding point. When the finger pressure head 207 rises to the highest point to maintain the pressure on the bleeding point, the No. 2 motor 21 reverses again, and repeats this process to simulate the reciprocating up and down pressing of the radial artery bleeding point by a human finger, thereby playing a role in activating the blood circulation. In this process, due to the reciprocating rotation of the No. 2 motor 21, the finger pressure head 207 will reciprocate around the rotating sphere 2084 to perform a rotational motion in the opposite direction during the reciprocating up and down motion, further simulating the rubbing effect of human fingers, and combined with the pressing effect, further improving the blood circulation effect on the bleeding point.

[0067] The present invention provides a massage component 208, which can be operated synchronously during the operation of the acupressure component 20, so that the device can simultaneously perform reciprocating up and down massage and reciprocating rotational kneading on the radial artery bleeding point. By utilizing the mutual cooperation of the two, a certain finger pressure is provided to prevent bleeding from the bleeding point, and the blood circulation effect on the bleeding point is also improved, thereby further preventing the probability of thrombosis and nerve damage.

[0068] When the driving component controls the pressing component to press down, the finger pressure component 20 is synchronously controlled to rise, and the pressing component and the finger pressure component 20 are controlled by the driving component to maintain reverse movement.

[0069] When the driving component is working, the control panel 7 is used to control the operation of the No. 2 motor 21. The rotation of the No. 2 motor 21 will drive the intermediate gear 18 to rotate. The intermediate gear 18 is respectively engaged with the compression component and the acupressure component 20, and drives the compression component and the acupressure component 20 to work. When the driving component controls the compression component to press down, the acupressure component 20 is synchronously controlled to rise. The compression component and the acupressure component 20 are controlled by the driving component to maintain reverse movement. The purpose of this setting is to shorten the switching time, because during the switching process of the compression component and the acupressure component 20, the driving component can be started to make the compression component and the acupressure component 20 rise or fall to a certain position. When the acupressure component 20 is completed, when the compression component is switched, the acupressure component 20 rises as a whole. At this time, since the compression component and the acupressure component 20 are controlled by the driving component to maintain reverse movement, the compression component will correspondingly fall and prepare for compression, which meets the work needs, shortens the switching time, and slows down the bleeding phenomenon of the bleeding point during the switching process.

[0070] It should be noted that when specifically realizing the effect of maintaining reverse motion of the compression component and the acupressure component 20 through the control of the driving component, it can be achieved by designing the rotation direction of the rotating adjustment gear 15 and the threaded rod 16, and adjusting the rotation direction of the worm 201 and the worm wheel 204.

[0071] By setting up a driving component, during the switching process of the switching component 6 between the compression component and the finger pressure component 20, the component to be worked on can be lowered and the component that has completed the work can be raised, thereby shortening the time it takes for the component to be worked on to be lowered after entering the work station, slowing down the bleeding phenomenon of the bleeding point during the switching process, and improving the working efficiency of the switching component 6.

[0072] like Figure 1 As shown, the retaining assembly 9 includes a telescopic rod 91 fixedly connected between the upper wrist piece 1 and the lower wrist piece 2, the output end of the telescopic rod 91 is sleeved with a fixing spring 92, and the lower end of the fixing spring 92 is fixedly connected to the lower wrist piece 2; elastic wristbands 93 are also provided on both sides of the lower wrist piece 2.

[0073] By adopting the above technical solution, when the switching component 6 is switched, since the upper wrist piece 1 has no parts to support it, it will fall to the wrist surface under the action of gravity, affecting the switching. By setting the retaining component 9, when fixing, first pass the wrist through two elastic wristbands 93, and then tighten the lock belt 4 and use Velcro 5 to bond and fix the lock belt 4, so that under the support of the spring 92 and the telescopic rod 91, the upper wrist piece 1 can be supported and keep a certain distance from the wrist, which is convenient for the operation of the switching component 6.

[0074] The working process of the technical solution of the present invention is as follows:

[0075] First, put the wrist between the upper wrist piece 1 and the lower wrist piece 2 to ensure that the bleeding position of the radial artery is at the center of the upper wrist piece 1 and the lower wrist piece 2. Then, pull the end of the locking belt 4 to make the upper wrist piece 1 and the lower wrist piece 2 approach each other and lock the wrist. After locking, use Velcro 5 to stick the locking belt 4 around the buckle 3 to fix it to complete the fixation of the wrist.

[0076] Afterwards, the control panel 7 is used to control the operation of the switching component 6, that is, the No. 1 motor 11 is operated, driving the switching shaft 12 to rotate, and then driving the switching frame 13 to rotate, and the compression component and the acupressure component 20 are respectively arranged at the two ends inside the switching frame 13. When the switching frame 13 rotates, the positions of the compression component and the acupressure component 20 can be switched. According to this operation, the compression component is first rotated to the corresponding bleeding position, and the compression component is pressed down to press against the bleeding point of the radial artery for compression. After a period of compression, the switching component 6 is used to switch the acupressure component 20 to the working position, and acupressure relaxation is performed.

[0077] While the finger pressure component 20 is working, the kneading component 208 is working synchronously, so that the finger pressure component 20 can not only achieve compression to stop bleeding, but also perform kneading, further playing a role in activating blood circulation and preventing nerve damage and thrombus formation.

[0078] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
