The invention belongs to the technical field of
medical instruments, and particularly provides a
radial artery hemostat for critical medical patients, which is composed of a
wrist strap, a frame, a host bottom plate, a power mechanism, a one-way valve, an observation window, a pressing piece, an
alarm device and a switch. According to the device, a motor drives a gear and a
threaded rod to transmit, a sliding
pipe is driven to push a pressure
piston in a hydraulic
pipe, and liquid is pressed into a pressing bin to push a pressing piece for pressing; pressure is monitored through the force sensitive
resistor, and when the pressure is too large, the
alarm device is automatically triggered to give an audible and visual alarm; the reverse rotation of the motor is matched with the
electromagnet to open the one-way valve to automatically relieve the pressure, and the popping shifting rod can be pulled in emergency to quickly pop out the host bottom plate. The device integrates accurate hydraulic driving,
pressure monitoring and alarming, convenient operation and rapid first-aid separation, and the problems that an existing
radial artery hemostat is not accurate in
pressure control, lacks an alarming mechanism and is complex in operation are effectively solved.
