Description
Technical field
This utility model relates to the auxiliary field of medical treatment, more precisely a kind of can root a tree name patient situation automatically to the hemostasis instrument of the band over-pressure safety device of tourniquet pressurization, venting.
Background technology
Electric pneumatic hemostasis instrument is the standing hemostatic device of department such as operating room, rescue room in the medical institutions.When the orthopaedics extremity are performed the operation, when wound is rescued, adopt gas pressure means blocking-up LBF, thereby reach anastalsis.Electric pneumatic ends instrument and adopts the micro-computer technology automatic pressure regulation, makes pressure keep constant, and the doctor also can increase and decrease pressure according to actual needs at any time, makes the hemostasis instrument reach optimum efficiency.Arrive the scheduled time, air pump stops qi of chong channel ascending adversely automatically, tourniquet pressure descends, and the limbs blood circulation recovers, and guarantees patient's safety.Yet need the medical worker rule of thumb to set the pressure of hemostasis instrument during clinical use, part patient's insufficient pressure causes producing the limbs venous congestion and causes the neural sanguineous infiltration that goes out, and part patient's hypertonia causes the damage of extremity vascular, nerve, muscle.Yet present hemostasis instrument can also not have the function of pretreatment and post processing according to the automatic required pressure of patient's limbs blood pressure.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hemostasis instrument that can regulate required pressure automatically according to patient's limbs blood pressure, have the band over-pressure safety device of pretreatment and post-processing function is provided.
The realization the technical solution of the utility model is: a kind of hemostasis instrument with over-pressure safety device, it is characterized in that: comprise tourniquet, box body, circuit board, circuit board and over-pressure safety device are housed in box body, described over-pressure safety device comprises detection control apparatus and switching device, and wherein switching device is connected between civil power and the protected electrical equipment; Wherein detection control apparatus comprises integrated resistor, diode and an audion; Described integrated resistor and back-biased diode are connected in turn between the base stage and emitter stage of audion; Storage module, single-chip microcomputer, sensor amplifying circuit, air pump drive circuit, inflation circuit, venting circuit, blood pressure measuring circuit, display driver circuit are housed on the circuit board.Inflator pump and rechargeable battery also are housed in the box body, nixie display is housed on the box body surface, described nixie display is LED charactron or LCD display, shows systolic pressure, diastolic pressure, frequency of pulse and work as preepipodite one systolic pressure to add 75mmHg, and lower limb one systolic pressure adds the 150mmHg number pressure.On the box body surface and on and off switch, automatic/hand selector switch, upper limb/lower limb selector switch, manually inflate and exit press button, power supply indicator be housed.External power interface, baroceptor input interface and air pump interface are equipped with in the box body side.One air bag is arranged in the tourniquet, baroceptor is housed in the air bag, there is nylon buckles at the tourniquet two ends, and the baroceptor conductor wire end has joint, and the inducing QI pipe end of air bag has interface.
Remarkable result of the present utility model: can regulate required pressure automatically, have the function of pretreatment and post processing according to patient's limbs blood pressure.
