Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

Arterial hemostatic device is a kind of medical instrument that needs to be compressed and hemostasis on the arterial wound after various interventional surgeries where the patient's artery is damaged and needs to enter the lesion area in the human body through the artery for inspection and treatment. Such arterial hemostats are mostly disposable consumables, so the arterial hemostat in the prior art needs to incorporate low cost into the product design. The binding tape is provided below the carrier sheet for compressing the arterial wound, and the two ends of the binding tape are connected with the ends of the carrier sheet located on both sides of the pressing sheet, so that the binding tape can be bundled with the limbs of the human body.

It can be used when the arteries on the limbs such as the carpal artery and the ankle artery form wounds, and when the arteries on the body such as the subclavian artery are wounded. It is difficult to use the binding tape for fixing, so the versatility is poor.

Second, the pressure of the tablet pressing on the arterial wound is formed by turning the knob to push the screw, so the pressure value is only judged by the experience of medical staff. The pain of compression hemostasis in large patients also increases the risk of secondary injury caused by compression hemostasis.
