Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a radial artery compressor for critically ill patients in a cardiology department. Background Art

[0002] In the clinical diagnosis and treatment of contemporary cardiovascular diseases, percutaneous radial artery puncture has become the preferred approach for interventional treatment in cardiology due to its significant advantages such as minimal trauma and rapid postoperative recovery. However, hemostasis and care of the postoperative puncture site are the key to ensuring patient safety and avoiding complications.

[0003] The commonly used radial artery compressor currently is a spiral compression type arterial compression hemostasis device, which is fixed to the wrist with a strap and then rotated by using the spiral handle so that the compression head applies downward pressure on the puncture point of the radial artery to achieve the purpose of hemostasis. Since the compressor is worn for a long time, continuous and complete blockage of blood flow will significantly increase the risk of radial artery occlusion and thrombosis. Therefore, it is necessary to intermittently release the compression on the radial artery, so as to achieve effective hemostasis while minimizing the risk of thrombosis, vascular occlusion and limb ischemia. At present, when relaxing the radial artery, the compressor must first be removed and then pressed with the fingers. This method is not only cumbersome and requires wearing it twice, but also during the operation, there will be a window period for pressing the radial artery, which will affect the hemostasis effect. In addition, the existing radial artery compressor does not have the massage function to prevent thrombosis or vascular occlusion. Therefore, the present application provides a radial artery compressor for critically ill patients in cardiology to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a radial artery compressor for critically ill patients in the cardiology department. A massaging component is added to the pressing component, which can intermittently compress and release the hemostatic point without adjusting the position of the massaging component. After releasing, it can be directly massaged, which simplifies the operation process and avoids secondary wearing. It can also ensure that the hemostatic point is continuously pressed without a window period, while preventing the risks of thrombosis or vascular occlusion, so as to solve the problem that when the existing compressor is released, it needs to be disassembled first and then pressed by fingers, resulting in a window period, and the existing radial artery compressor has no massaging function to prevent thrombosis or vascular occlusion.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A radial artery compressor for critically ill patients in a cardiology department comprises a fixing plate with a strap provided on the outer side of the fixing plate; a pressing assembly for pressing a hemostatic point on the patient's radial artery to stop bleeding, and the pressing assembly is connected to the fixing plate; the pressing assembly comprises a knob rotatably connected to the inside of the fixing plate, a rotating rod is threadedly connected to the inside of the knob, the bottom end of the rotating rod is fixedly connected to the connecting plate, and sliding rods are symmetrically slidably connected to the two ends of the connecting plate, and the two ends of the sliding rod pass through the connecting plate and are fixedly connected to a compression head; a massaging assembly for rubbing the hemostatic point after the pressing assembly is released, and the massaging assembly is connected to the rotating rod and the compression head; a locking assembly for switching the rotation or fixation of the massaging assembly, and the locking assembly is connected to the rotating rod and the massaging assembly.

[0007] Optionally, the massage assembly includes an insertion rod rotatably connected to the inside of the rotary rod, the top end of the insertion rod extends to the outside of the knob and is fixedly connected to a rotating cover, the inside of the insertion rod is slidably connected to a connecting rod, the bottom end of the connecting rod is fixedly connected to a cam plate, and the cam plate contacts the inner wall of the compression head when rotating.

[0008] Optionally, a fixing sleeve is fixedly connected inside the compression head and outside the connecting rod, and a tapered through hole is opened inside the fixing sleeve.

[0009] Optionally, a tapered plug is provided on the outer side of the insertion rod, and the outer wall of the tapered plug fits with the side wall of the tapered through hole.

[0010] Optionally, slots are provided at equal intervals inside the connecting rod, and plug posts are fixedly connected at equal intervals inside the plug rod, and the plug posts are inserted into the slots.

[0011] Optionally, the locking assembly includes a clamping piece symmetrically fixed to the outside of the insertion rod, a positioning groove for accommodating the clamping piece is symmetrically opened inside the rotating rod, an annular groove is opened inside the rotating rod and above the positioning groove, and an annular protrusion is provided inside the rotating rod and below the annular groove.

[0012] Optionally, the knob passes through the outside of the fixed plate and is located below the rotating cover and is fixedly connected to a plurality of paddles at equal intervals.

[0013] Optionally, an elastic member is symmetrically fixedly connected to the outer side of the connecting plate, and one end of the elastic member away from the connecting plate is fixedly connected to the inner wall of the pressing head.

[0014] Optionally, a silicone pad is fixedly connected to the bottom of the fixing plate, and a concave portion is provided on a side of the fixing plate away from the silicone pad.

[0015] Optionally, the outer cover of the compression head is provided with a soft isolation cover.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, the radial artery compressor for critically ill patients in the cardiology department provided by this application realizes intermittent compression and release operations on the hemostatic point by adding a massaging component to the pressing component. This design does not require adjustment of the position of the massaging component, and can directly massage the hemostatic point after the compressor releases it. This not only simplifies the operating process and avoids the secondary wearing of the compressor, but also ensures a continuous and window-free compression effect on the hemostatic point. In addition, using the massaging component to massage the hemostatic point can also effectively prevent potential risks such as thrombosis or vascular occlusion.

[0018] The locking components equipped on the rotating rod and the insertion rod allow the rotation and fixed states of the massage component to be flexibly switched. This design not only effectively prevents the compression head from swinging due to accidental touch by the patient, but also makes locking and unlocking easy to operate, requiring only plugging and unplugging, greatly facilitating the operation of medical staff.

[0019] By arranging an elastic part between the compression head and the connecting plate, auxiliary force can be provided for the resetting of the compression head after massaging. At the same time, with the cooperation of the conical plug and the conical barrel, the compression head can be further repositioned by pressing, ensuring that the compression head can be accurately repositioned to just above the hemostasis point after massaging, thereby ensuring the subsequent compression effect on the radial artery.

[0038] like Figures 1 to 4 As shown, an embodiment of the present invention provides a radial artery compressor for critically ill patients in the cardiology department, including a fixing plate 1, a strap 101 is provided on the outside of the fixing plate 1, a silicone pad 103 is fixedly connected to the bottom of the fixing plate 1, and an inner recess 102 is provided on the side of the fixing plate 1 away from the silicone pad 103. With the cooperation of the inner recess 102 and the silicone pad 103, the wearing position of the fixing plate 1 can be assisted in positioning, and the inner recess 102 is designed as an arc, which can improve the fit with the wrist. The fixing plate 1 can be pre-fixed at the wrist through the strap 101, which is convenient for subsequent tightening or loosening adjustment. A plurality of through grooves are also provided on the fixing plate 1 to facilitate heat dissipation and improve wearing comfort.

[0039] The embodiment of the present invention also includes a pressing component, which is used to press the hemostatic point on the patient's radial artery to stop bleeding. The pressing component is connected to the fixing plate 1; the pressing component includes a knob 2 that is rotatably connected to the inside of the fixing plate 1, and an internal thread is provided in the knob 2. The knob 2 passes through the outside of the fixing plate 1 and is equidistantly fixedly connected to a plurality of paddles 201 below the rotating cover 4. The paddles 201 are convenient for driving the knob 2 to rotate, thereby improving the smoothness of the rotation. The knob 2 is internally threaded with a rotating rod 202, and the rotating rod 202 The bottom end is fixedly connected to a connecting plate 203, and both ends of the connecting plate 203 are symmetrically slidably connected to sliding rods 204. Both ends of the sliding rod 204 pass through the connecting plate 203 and are fixedly connected to a compression head 205. By turning the knob 2, the rotating rod 202 can be driven to rise and fall, and the rotating rod 202 can drive the connecting plate 203, the sliding rod 204 and the compression head 205 to move, so as to achieve compression or release operation on the radial artery hemostasis point, thereby reducing the risk of radial artery occlusion and thrombosis while meeting the requirements of compression hemostasis.

[0040] The outer cover of the compression head 205 is provided with a soft isolation cover, which not only protects the compression head 205 and avoids direct contact with blood, facilitating subsequent cleaning, but also the soft isolation cover can better fit the skin. At the same time, it can also improve the comfort of the patient wearing it. The outer side of the connecting plate 203 is symmetrically fixedly connected with an elastic member 3, and the end of the elastic member 3 away from the connecting plate 203 is fixedly connected to the inner wall of the compression head 205. The elastic member 3 can provide auxiliary force for resetting after the compression head 205 is massaged, making it convenient to reposition the compression head 205 to directly above the hemostasis point.

[0041] The kneading assembly is used to knead the hemostatic point after the pressing assembly is released, and the kneading assembly is connected to the rotating rod 202 and the compression head 205; the locking assembly is used to switch the rotation or fixation of the kneading assembly, and the locking assembly is connected to the rotating rod 202 and the kneading assembly.

[0042] like Figures 2 to 8As shown, the massage assembly includes an insertion rod 401 that is rotatably connected to the inside of the rotary rod 202, the top of the insertion rod 401 extends to the outside of the knob 2 and is fixedly connected to the rotating cover 4, the insertion rod 401 is slidably connected to the inside of the connecting rod 403, slots 405 are equidistantly provided inside the connecting rod 403, and the insertion rod 406 is equidistantly fixedly connected to the inside of the insertion rod 401, and the insertion column 406 is inserted into the inside of the slot 405, the bottom end of the connecting rod 403 is fixedly connected to the cam plate 404, and the cam plate 404 conflicts with the inner wall of the compression head 205 when rotating, and the cam plate 404 includes a disc and three protrusions arranged on the disc. This design makes The cam plate 404 rotates one circle to drive the compression head 205 to swing three times, which is not only convenient for medical staff to operate, but also can increase the swinging speed of the compression head 205. The rotating cover 4 can drive the insertion rod 401 to rotate. Since there are mutually engaged slots 405 and insertion columns 406 between the insertion rod 401 and the connecting rod 403, it will not affect the sliding of the insertion rod 401 on the connecting rod 403. When the insertion rod 401 rotates, it can also drive the connecting rod 403 and the cam plate 404 to rotate, so that the cam plate 404 drives the compression head 205 to swing, so as to achieve massage and relief of the radial artery hemostasis point.

[0043] like Figure 2 and Figure 4 As shown, a fixed sleeve 5 is fixedly connected inside the compression head 205 and on the outside of the connecting rod 403. A tapered through hole is provided inside the fixed sleeve 5. A tapered plug 402 is provided on the outside of the insertion rod 401, and the outer wall of the tapered plug 402 fits the side wall of the tapered through hole. Since the tapered plug 402 is adapted to the inclined surface of the tapered through hole, when the tapered plug 402 moves downward, it can drive the fixed sleeve 5 to follow, and then the fixed sleeve 5 can drive the compression head 205 to reset, so that the compression head 205 moves again to the top of the hemostasis point, which is convenient for subsequent hemostasis compression.

[0044] like Figure 7 and Figure 9As shown, the locking assembly includes a clamping piece 601 symmetrically fixed to the outside of the insertion rod 401, the clamping piece 601 is an elastic component, and is provided with two, the rotating rod 202 is symmetrically provided with two positioning grooves 602 for accommodating the clamping piece 601, the rotating rod 202 is provided with an annular groove 603 inside and above the positioning groove 602, and the rotating rod 202 is provided with an annular protrusion 604 inside and below the annular groove 603. The clamping piece 601 can be driven downward by moving the insertion rod 401 downward, thereby clamping the clamping piece 601 into the positioning groove The inside of the groove 602 can realize the positioning of the insertion rod 401, prevent the cam plate 404 from rotating due to accidental touch, and thus ensure the stability of the compression head 205 on the hemostasis point. The insertion rod 401 can drive the clamping part 601 to move up to the inside of the annular groove 603. Under the action of the annular protrusion 604, the clamping part 601 and the insertion rod 401 can be kept in the current position, which is convenient for medical staff to drive the insertion rod 401, the connecting rod 403 and the cam plate 404 to rotate continuously through the rotating cover 4, so as to achieve sufficient massage of the hemostasis point by the compression head 205.

[0045] The workflow of the technical solution of the present invention is as follows:

[0046] The compression head 205 is then adjusted to align with the hemostatic point of the radial artery by tightening the bandage 101 to secure the compression device to the patient's wrist. The inner concave portion 102 and the silicone pad 103 work together to assist in positioning the compression device, thereby effectively preventing displacement of the compression device from occurring on the wrist. The knob 202 is rotated by turning the paddle 201, and the knob 2 in turn drives the rotary rod 202 downward. When the rotary rod 202 moves, the connecting plate 203, the sliding rod 204 and the compression head 205 move downward together, so that the compression head 205 applies pressure to the hemostatic point. Since the compression of the radial artery needs to be performed intermittently, when the compression force on the radial artery needs to be released, the knob 2 is simply reversed, and the knob 2 will drive the rotary rod 202, the connecting plate 203 and the compression head 205 to move upward, thereby releasing the compression force on the hemostatic point.

[0047] Then, the rotating cover 4 is pulled upward, and the rotating cover 4 drives the insertion rod 401 and the clamping piece 601 to move upward together. During this process, the insertion rod 401 slides outside the connecting rod 403. At the same time, the insertion rod 401 drives the insertion column 406 to slide upward inside the slot 405, and the clamping piece 601 moves out from the positioning groove 602. When the clamping piece 601 moves to the inside of the annular groove 603, due to the interference of the annular groove 603, the clamping piece 601 is restricted in the annular groove 603. At this time, the insertion rod 401 is driven to rotate by the rotating cover 4, and the insertion rod 401 cooperates with the connecting rod 403 to drive the cam plate 404 to rotate. When the cam plate 404 rotates, it interferes with the inner wall of the compression head 205 and drives the compression head 205 to slide. At this time, the compression head 205 drives the sliding rod 204 to slide back and forth inside the connecting plate 203, thereby realizing the massaging action of the compression head 205 on the hemostasis point, which helps to prevent the risk of thrombosis or vascular occlusion.

[0048] When it is necessary to press the hemostasis point again, the rotating cover 4 is pressed downward, and the rotating cover 4 drives the insertion rod 401 and the clamping member 601 to move downward, so that the clamping member 601 is moved out from the inside of the annular groove 603 and moved to the horizontal position of the positioning groove 602 again. The rotating insertion rod 401 drives the clamping member 601 to move to the inside of the positioning groove 602, so as to achieve the locking of the massage component. The elastic members 3 on both sides of the connecting plate 203 can push the compression head 205 to move in the center, and assist the compression head 205 to reset to the hemostasis point. At the same time, the insertion rod 401 is moved downward. During the movement, the conical plug 402 is driven to move downward. When the conical plug 402 fits with the side wall of the conical through hole inside the fixed sleeve 5, the conical plug 402 drives the fixed sleeve 5 to move, thereby forcing the fixed sleeve 5 to drive the compression head 205 to move again. When the conical plug 402 is completely fitted with the conical through hole inside the fixed sleeve 5, the compression head 205 can be accurately reset. Then, the knob 2 is turned again to make the rotary rod 202 drive the connecting plate 203 and the compression head 205 to move downward, thereby pressing the compression head 205 tightly on the hemostasis point.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
