hemostat

Abstract

A hemostat comprises a compressing body (2) and a regulating component (3). The compressing body (2) is provided with an inner cavity (20) that is capable of containing liquid and the effective volume of which can be changed according to the amount of the liquid in the inner cavity (20). The regulating component (3) is provided with a liquid storage cavity (30) for containing liquid. The liquid storage cavity (30) is in communication with the inner cavity (20). The regulating component (3) is used for regulating the relative amount between liquid in the liquid storage cavity (30) and liquid in the inner cavity (20) so that the liquid can flow between the liquid storage cavity (30) and the inner cavity (20) and the pressure applied by the compressing body (2) can be changed. According to the provided hemostat, because the liquid is sealed between the two cavities (20, 30), a control valve is not needed to obtain the hemostat and an external liquid source is also not needed, so that the manufacturing cost and the using cost are effectively reduced, and the compressing force of the compressing body (2) can be regulated very conveniently. Because liquid serves as a working medium, the flow direction is easy to change, which facilitates space arrangement of the components in use locations and avoids a hidden danger caused by a collision between the regulating component (3) and another object; the condition of a hemorrhagic spot can be seen very easily, and the hemostat has a good using effect and high reliability.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a hemostat. Background technique [0002] Current hemostats, such as radial hemostats, mostly compress the bleeding point through an air bag. Its airbag is operated by an external syringe. The balloon must be connected to the syringe every time the pressure is adjusted. The operation is inconvenient and requires high experience for the operator. It is clinically required to decompress the pressure regularly to prevent radial artery complications during the hemostasis process. Therefore medical personnel need repeatedly to reduce gas with syringe, and workload is quite large. [0003] In the prior art, it is also possible to press the bleeding point by driving the pressure plate with air pressure or hydraulic pressure. The air pressure or hydraulic cylinder is arranged vertically and located directly above the pressure plate, and an air (liquid) hole or a gas (liquid) hole is...

AI Technical Summary

Problems solved by technology

The above-mentioned structure must also be externally connected with an air source or a liquid source, which has the same disadvantages as the above-mentioned air bag hemostat

Moreover, since the air pressure or hydraulic device is arranged vertically, the protruding surface of the hemostat is relatively high, and it is easy to collide with the outside world, resulting in compression and displacement, causing bleeding and discomfort to the patient

At the same time, the hemostat using the longitudinal platen structure is not conducive to observing the bleeding point because the air pressure or hydraulic device is arranged directly above the bleeding point.
