Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a novel intracardiac clinical compression rapid hemostasis device. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a clinical department set up in the general internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, etc. When treating patients, the brachial artery located between the biceps and triceps is often selected for puncture. After the puncture is completed, the brachial artery wound needs to stop bleeding. When stopping bleeding, in order to allow the blood in the wound to flow normally and ensure blood supply to the wound, it is best to use pressure to stop bleeding.

[0003] At present, hospitals usually choose to bandage patients directly after puncture. However, this direct bandaging cannot achieve the compression effect. Since there are many patients in the hospital and the medical staff are busy, it is easy to delay the other work of the medical staff by pressing to stop the bleeding for the patient, resulting in a shortage of staff in the hospital. In addition, the existing pressing device is not decompressed in time or the pressure is too high, which can easily damage the nerves and cause abnormal limb sensation or movement.

The movable plate 605 is L-shaped, and the inner wall is fixedly connected to teeth that match the block 602. The outer surface of the rotating shaft 604 is sleeved with a first torsion spring 606. The left and right ends of the first torsion spring 606 are respectively connected to the second movable groove 603 and the movable plate 605. Figure 6 As shown, this structure is used for the adjustment rod 507 to move downward along the first movable groove 501, so that the blocks 602 on both sides of the adjustment rod 507 push the movable plate 605, and the movable plate 605 swings under the action of the rotating shaft 604 and the first torsion spring 606. When the adjustment rod 507 drops to a suitable position, under the elastic action of the first torsion spring 606, the teeth at the movable plate 605 are inserted into the gap of the block 602 to fix the adjustment rod 507. When decompression is required, it is only necessary to press the outer end of the movable plate 605, and the movable plate 605 is rotated through the rotating shaft 604 to disengage the teeth on the inner side of the movable plate 605 from the gap of the block 602, and under the rebound action of the pressure spring 506, the adjustment rod 507 is restored to its original position, and decompression is timely.

[0032] Furthermore, a fixing assembly 7 is provided inside the support frame 1, and the fixing assembly 7 includes a fixing rod 701, a right clamping plate 702, a left clamping plate 703, a first clamping slot 704, a second clamping slot 705, and a second torsion spring 706. The fixing rod 701 is fixedly connected to the center of the inner wall of the support frame 1, the right side of the fixing rod 701 is rotatably connected to the right clamping plate 702, the left side of the fixing rod 701 is rotatably connected to the left clamping plate 703, the inner wall of the left clamping plate 703 is provided with a first clamping slot 704, the inner wall of the fixing rod 701 is provided with a second clamping slot 705, and the outer side of the fixing rod 701 is sleeved with a second torsion spring 706, and the two ends of the second torsion spring 706 are respectively against the first clamping slot 704 and the second clamping slot 705. Figure 5 As shown, the structure is used to place the patient's limbs in the right splint 702 and the left splint 703, which are rotatably connected to the fixing rod 701 during placement, so that the right splint 702 and the left splint 703 are rotated outward, and at the same time, the second torsion spring 706 is deformed. Under the elastic action of the second torsion spring 706, the inner walls of the right splint 702 and the left splint 703 are fitted to the patient's limbs to fix the patient's limbs and avoid displacement. At the same time, it can be used by patients of different body shapes, thereby improving the applicability of the device.

[0033] Furthermore, a timer 8 is fixedly installed inside the support frame 1, and two sets of limit blocks 11 are fixedly connected to the inner wall of the support frame 1. The right clamping plate 702 and the left clamping plate 703 are limited to keep the right clamping plate 702 and the left clamping plate 703 in an open state. The four corners of the support frame 1 are provided with anti-skid pads to prevent the device from sliding when placed, thereby enhancing the stability of the device. Figure 2 As shown, the structure is used to start the timer 8 to time the device, and remind the medical staff to decompress after the specified time is reached, so as to ensure smooth blood circulation in the distal limbs of the patient and avoid the occurrence of adverse reactions such as tissue ischemia and hypoxia.

[0034] Furthermore, the outer surface of the adjusting rod 507 is provided with scale lines 9, and the lower end of the pressing plate 504 is fixedly connected with an air cushion 10. Figure 3 As shown, this structure is used to clearly observe the descending distance of the adjustment rod 507 through the scale line 9, so as to facilitate the adjustment of the adjustment rod 507. The setting of the air cushion 10 helps to reduce the patient's pain and discomfort and improve the patient's comfort.

[0035] Furthermore, the inner walls of the right clamping plate 702 and the left clamping plate 703 are fixedly connected with a protective pad 12. Figure 2 As shown, when the structure is used to fix the limbs through the right splint 702 and the left splint 703 , the safety and comfort of the patient are ensured under the action of the protective pad 12 on the inner wall of the right splint 702 and the left splint 703 .

[0036] Furthermore, the slider 502 is spherical, and the diameter of the first movable groove 501 is adapted to the slider 502. Figure 4 As shown, the structure is used to make the slider 502 spherical. When the pressing plate 504 descends, the pressing plate 504 can move up and down stably under the action of the slider 502 because the surface morphology of the patient's limbs is complex and changeable and cannot be subjected to vertical force.

[0037] Working principle: When used, Figure 1 and Figure 5 As shown, the patient's limbs are first placed in the right splint 702 and the left splint 703. When placed, the right splint 702 and the left splint 703 are rotatably connected to the fixing rod 701, so that the right splint 702 and the left splint 703 are rotated outward, and the second torsion spring 706 is deformed at the same time. Under the elastic action of the second torsion spring 706, the inner walls of the right splint 702 and the left splint 703 are attached to the patient's limbs to fix the patient's limbs to avoid displacement. Then, the positioning tube 3 is fixed to the surface of the support rod 2 by winding the straps 4 on both sides, and the positioning tube 3 is moved to the corresponding position, as shown in FIG. Figure 4 and Figure 6As shown, the pressing plate 504 is aligned with the hemostasis position, and the adjusting rod 507 is pressed. The adjusting rod 507 drives the second gasket 508 to move downward along the first movable groove 501, and squeezes the pressure spring 506, thereby pushing the first gasket 505 and the slider 502 to move downward along the first movable groove 501. When the adjusting rod 507 moves downward along the first movable groove 501, the blocks 602 on both sides of the adjusting rod 507 push the movable plate 605, and the movable plate 605 swings under the action of the rotating shaft 604 and the first torsion spring 606. When the adjusting rod 507 drops to a suitable position, under the elastic action of the first torsion spring 606, the teeth at the movable plate 605 are inserted into the gap of the block 602, the adjusting rod 507 is fixed, and the pressing plate 504 at the lower end of the connecting rod 503 is attached to the patient's hemostasis site to press and stop bleeding, as shown in FIG. Figure 2 As shown, after pressing is completed, the timer 8 is started to count. When the specified time is reached and decompression is required, the timer 8 sends an alarm to remind the staff. The staff needs to press the outer end of the movable plate 605, and the movable plate 605 is rotated through the rotating shaft 604 to disengage the teeth on the inner side of the movable plate 605 from the gap of the block 602, and under the rebound action of the pressure spring 506, the adjustment rod 507 is restored to its original position and decompression is timely. The above is the entire working principle of the present invention.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
