Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a compression hemostasis device. Background Art

[0002] In the event of an emergency or postoperative bleeding, the quickest way to prevent excessive bleeding is usually to stop the bleeding of the wound. Compression hemostasis involves temporarily closing the artery near the wound to stop bleeding. To ensure the accuracy of the pressing position and a good hemostatic effect, medical staff are required to perform manual compressions in clinical practice, and they cannot leave the area while doing so. This is very labor-intensive and can easily lead to staff shortages.

[0003] For example, the compression hemostasis device with Chinese patent number CN218451634U has an upward curved rotating frame in this utility model, which fits the patient's limbs, prevents excessive squeezing of the skin, and improves the comfort of use. However, a relatively slender pressure rod is provided under the rotating frame in this utility model, resulting in excessive concentration of pressure near the patient's wound, causing the device to be only applicable to smaller wounds, reducing the application range of the device and being inconvenient for users to use. Therefore, a compression hemostasis device is proposed to solve the above problems. Utility Model Content

[0027] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and omits detailed descriptions of known functions and known components. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art just because it is included in this section.

[0028] During implementation, follow these steps:

[0029] 1) First, pass the part of the body that needs compression and hemostasis, such as the arm, through the opening between the arc segment 1 and the binding belt 303, so that the wound is between the arc pad 2 and the binding belt 303;

[0030] 2) Then, use the curved pad 2 to press the dressing on the wound, and then start the output shaft of the reduction motor 304 to rotate, driving the winding rod 305 to rotate;

[0031] 3) Finally, the excess binding band 303 is wound around the reeling rod 305 to shrink the opening between the arc segment 1 and the binding band 303, thereby firmly compressing the wound and surrounding blood vessels.

[0032] To sum up, the compression hemostasis device utilizes the width of the arc pad 2 to ensure the compression range and avoid pressure concentration that causes secondary bleeding in the wound. At the same time, with the help of the flexible binding belt 303, when it contracts, it ensures the comfort of the patient when using it, reduces the impact of pressure damage, and further facilitates the use of the user. At the same time, the reduction motor 304 is set above the arc segment 1, thereby increasing the gravity of the arc segment 1, increasing the pressure on the wound and nearby blood vessels, achieving the purpose of effective hemostasis, further facilitating the use of medical staff, and expanding the scope of application of the device.

[0033] Moreover, with the help of the design of the pressure-reducing roller 308 and the direction-changing roller 309, the strapping belt 303 is prevented from rubbing against the entrance of the hole structure when passing through the guide cavity 306, the strap hole 307 and the inner sliding hole 310, thereby avoiding damage to the strapping belt 303 due to friction, extending the service life of the device, and further facilitating the operation and use of medical staff. At the same time, the structure can guide the left end of the strapping belt 303 to the vicinity of the winding rod 305, facilitating the connection with the winding rod 305, further facilitating the use of the user, and solving the problems in the comparative documents of narrow adaptability, reduced ease of use, and inconvenience for users.
