Hemostat

Abstract

The invention is suitable for the field of medical instruments and discloses a hemostat. The hemostat comprises a compressing body and a regulating component, wherein the compressing body is provided with an inner cavity capable of containing liquid, and the effective volume of the inner cavity can be changed through the amount of the liquid in the inner cavity; the regulating component is provided with a liquid storage cavity for containing liquid, the liquid storage cavity is communicated with the inner cavity, and the regulating component is used for regulating the relative amount of liquid in the liquid storage cavity and liquid in the inner cavity so that the liquid can flow between the liquid storage cavity and the inner cavity and the pressure applied by the compressing body can be changed. According to the hemostat, because the liquid is sealed between the two cavities, a control valve is not needed to obtain the hemostat and an external liquid source is not needed further, the manufacturing cost and the using cost are effectively reduced, and the compressing force of the compressing body can be conveniently regulated. Because liquid serves as the working medium, the flow direction is easy to change, all the components can be arranged in space of the using positions easily, hidden danger caused by collision between the regulating component and other objects is avoided, the conditions of a hemorrhagic spot can be seen easily, and the hemostat is good in using effect and high in 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.
