Description

Technical Field

[0001] The utility model relates to the technical field of cardiology medical equipment, in particular to a radial artery compressor. Background Art

[0002] Coronary atherosclerotic heart disease is a heart disease caused by atherosclerotic lesions in the coronary arteries, which leads to stenosis or obstruction of the blood vessel lumen, resulting in myocardial ischemia, hypoxia or necrosis. It is called coronary heart disease and is clinically divided into stable coronary heart disease and acute coronary syndrome. Among the various surgical options for the treatment of coronary heart disease, radial artery puncture interventional surgery has the advantages of fewer complications, rapid wound healing, simple postoperative treatment, and no need for patients to stay in bed. Therefore, operations such as angiography and stent placement through the radial artery have become one of the most important means of diagnosing and treating coronary heart disease. After the interventional surgery, a radial artery compressor is generally used to stop bleeding. The existing radial artery compressor can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] The existing one is directly mounted on the radial artery puncture site of the patient. In order to avoid wound rupture, the patient needs to reduce the movement of the arm position. However, in actual use, since the radial artery compressor is directly mounted on the patient's arm, the burden on the arm is increased. In addition, since there is no limit function, the patient is prone to move at will, increasing the possibility of wound rupture. The safety of the device is not strong. For this reason, we propose a radial artery compressor. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a radial artery compressor, which enables the patient to directly place his arm on the compression splint for support after inserting his arm between the two groups of compression splints through the provision of a first rotating shaft, a gear and a push rod, thereby reducing the burden on the patient's arm. The adjusting gear is then rotated to cause the adjusting gear to drive the gear to rotate under the restriction of the first rotating shaft, and the two groups of gears rotate synchronously and drive the push rod to move. The push rod drives the limiting rod to rotate under the restriction of the second rotating shaft, so that the push rod can push the compression splint to move under the restriction of the second rotating shaft, and the distance between the two groups of compression splints is shortened and fits on the patient's arm to perform compression and hemostasis. When the patient needs to adjust the position of his arm, he pushes the supporting rod to cause the supporting rod to drive the slide to move under the restriction of the slide rail, and the position of the arm and the compression splint is adjusted accordingly. The slide rail can be fixed on the side of the bed, thereby avoiding the problem that the radial artery compressor is directly sleeved on the patient's arm, which increases the burden on the arm, and the patient is prone to move at will due to the lack of a limiting function, which increases the possibility of wound rupture, thereby improving the safety of the device.

[0030] Two sets of second rotating shafts 25 are symmetrically arranged on one side of the inner wall of the housing 1 near the compression clamping plate 26, and a rotatable limiting rod 24 is arranged at the connection between the push rod 23 and the compression clamping plate 26, and the other end of the limiting rod 24 is inserted into the interior of the housing 1 and rotatably sleeved on the surface of the second rotating shaft 25;

[0031] A support rod 28 is fixedly mounted on the outer wall of the housing 1 at one side away from the compression clamp 26 , and a slide table 29 is fixedly mounted on the bottom end of the support rod 28 , and a slide rail 3 is provided through the middle of the slide table 29 .

[0032] When compression is required to stop bleeding on the patient, the patient's arm is inserted between the two groups of compression splints 26, and the arm can be directly placed on the compression splint 26 for support, thereby reducing the burden on the patient's arm, and then the adjusting gear 27 is rotated, so that the adjusting gear 27 drives the gear 22 to rotate under the restriction of the first rotating shaft 21, and the two groups of gears 22 rotate synchronously and drive the push rod 23 to move, and the push rod 23 drives the limiting rod 24 to rotate under the restriction of the second rotating shaft 25, so that the push rod 23 can push the compression splint 26 to move under the restriction of the second rotating shaft 25, and the distance between the two groups of compression splints 26 is shortened and fits on the patient's arm to stop bleeding;

[0033] When the patient needs to adjust the position of the arm, the support rod 28 is pushed so that the support rod 28 drives the slide 29 to move under the restriction of the slide rail 3, and the position of the arm and the compression splint 26 is adjusted accordingly. The slide rail 3 can be fixed to the side of the bed, which improves the safety of the device.

[0034] In other embodiments, only a portion of teeth are provided on the surface of the lower gear 22;

[0035] Through this design, the device can control the maximum and minimum values ​​of the clamping tightness of the compression clamping plate 26 by the number of teeth on the surface of the lower gear 22 .

[0036] In other embodiments, the portion of the adjusting gear 27 that passes through the outer wall of the housing 1 is rotatably connected to the outer wall of the housing 1;

[0037] With this design, medical personnel or patients can adjust the clamping tightness of the compression splint 26 by rotating the portion of the adjustment gear 27 that passes through the outer wall of the housing 1 .

[0038] In other embodiments, the support rod 28 is composed of an upper adjustment section connected to the housing 1 and a lower fixed section connected to the slide 29;

[0039] A groove is formed at the top of the lower fixed section of the support rod 28, and a plurality of limit grooves 44 are formed at equal intervals on the inner wall of the groove. The upper adjustment section is rotatably hinged in the groove, and a plurality of groups of spring grooves 41 are formed at equal intervals on the outer wall of the hinge portion of the upper adjustment section, and a limit pin 43 is formed through the outer surface of the spring groove 41. A first spring 42 is formed on the inner wall of the spring groove 41, and the other end of the first spring 42 is connected to the inner end surface of the limit pin 43, and the limit pin 43 can be inserted into the limit groove 44.

[0040] When the angle of the compression splint 26 needs to be adjusted, the shell 1 is rotated so that the shell 1 can drive the upper adjustment section of the support rod 28 to rotate, so that the upper adjustment section drives the limit pin 43 to rotate through the spring groove 41 and releases the inner wall of the limit groove 44. The limit pin 43 moves and squeezes the first spring 42 under the push of the limit groove 44, and the limit pin 43 can be retracted into the spring groove 41. The lock between the limit pin 43 and the limit groove 44 is released, and the upper adjustment section of the support rod 28 can adjust the angle within the limit of the lower fixed section, thereby achieving the purpose of adjusting the angle of the compression splint 26 according to the needs of the patient, thereby improving the comfort of the device;

[0041] After the adjustment is completed, the elastic deformation of the first spring 42 is restored to make the limit pin 43 pop out from the spring groove 41 again and be inserted into another limit groove 44, thereby achieving the purpose of re-limiting the upper adjustment section and the lower fixed section of the support rod 28 through the limit pin 43 and the other limit groove 44.

[0042] In other embodiments, the outer ends of the limiting pins 43 are all configured to be arc-shaped, and the limiting grooves 44 are all configured to be arc-shaped grooves that cooperate with the limiting pins 43;

[0043] Through this design, when the outer end of the limit pin 43 is subjected to an external force with a force angle of a specific arc, the limit pin 43 can be displaced and move out from the limit groove 44, thereby achieving the purpose of releasing the limit pin 43 and the limit groove 44 from the restriction on the adjustment section of the support rod 28.

[0044] In other embodiments, a rod insertion groove 51 is integrally formed at the bottom end of the slide 29, and a pull rod 54 is provided through the bottom end of the rod insertion groove 51, and a rod 52 is connected to the top end of the pull rod 54, and the rod 52 passes through the top end of the inner wall of the rod insertion groove 51 and is inserted into the slide 29, and a second spring 55 is wound around the surface of the rod insertion groove 51, and one end of the second spring 55 is connected to the top end of the inner wall of the rod insertion groove 51, and the other end is connected to the top end of the pull rod 54;

[0045] The bottom of the slide rail 3 is provided with multiple sets of slots 53 arranged at equal distances, and the slots 53 can all be inserted with the insertion rods 52;

[0046] When it is necessary to drive the slide 29 to move on the surface of the slide rail 3 through the lower fixed section of the support rod 28, the pull rod 54 is pulled, so that the pull rod 54 drives the insertion rod 52 to move out of the slot 53 and into the insertion rod slot 51. During the collection process, the insertion rod 52 pulls the second spring 55 to produce elastic deformation, and the insertion rod 52 no longer cooperates with the slot 53 to limit the position of the slide 29;

[0047] After the slide 29 has completed its movement on the surface of the slide rail 3, the pull rod 54 is released, and the pull rod 54 no longer pulls the second spring 55. The second spring 55 recovers its elastic deformation and pulls the insertion rod 52 to reset. The insertion rod 52 inserts itself into another slot 53. The insertion rod 52 cooperates with the other slot 53 to limit the position of the slide 29, and the position adjustment of the compression splint 26 is completed.

[0048] In other embodiments, the top and bottom of the inner wall of the slide 29 are provided with ball grooves 61, and the ball grooves 61 are provided with rollable balls 62 embedded therein;

[0049] The top and bottom of the outer wall of the slide rail 3 are provided with guide grooves 63 at positions corresponding to the positions of the balls 62, and the balls 62 can roll along the inner walls of the guide grooves 63;

[0050] Through this design, when the slide 29 moves on the surface of the slide rail 3, it can drive the ball 62 to roll on the surface of the guide groove 63 through the ball groove 61. The slide 29 moves on the surface of the slide rail 3 through the ball 62 and the guide groove 63, thereby reducing the contact area between the slide 29 and the slide rail 3, thereby improving the smoothness of the slide 29 when moving on the surface of the slide rail 3.
