Description

A kind of hemostasis instrument with overcurrent protection

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 overcurrent protection 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 overcurrent protection of pretreatment and post-processing function is provided.

The realization the technical solution of the utility model is: a kind of hemostasis instrument with overcurrent protection, it is characterized in that: comprise tourniquet, box body, circuit board, circuit board and overcurrent protection are housed in box body, described overcurrent protection comprises current transformer, sampled rectifier circuit and signal processing circuit, and described sampled rectifier circuit comprises the shunt of at least four group rectification circuits and at least three current transformers; Two commutation diodes of every group of rectification circuit branch route are in series; One of them outfan of the secondary side of described at least three current transformers inserts respectively between one group of rectification circuit, two commutation diodes along separate routes; Another outfan is respectively through behind the sample resistance, and is in parallel with an end of a ground connection sample resistance; The other end of ground connection sample resistance is connected between a remaining rectification circuit two commutation diodes along separate routes, and described signal processing circuit is inserted at the two ends of each sample resistance and ground connection sample resistance respectively simultaneously; 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.

Description of drawings

Accompanying drawing l is structural representation of the present utility model;

Accompanying drawing 2 is the structure chart of tourniquet of the present utility model.

The specific embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, this utility model is limited.

The pressure of well-known tourniquet, the way of science is the systolic pressure according to patient's limbs, determine the pressure of tourniquet, with regard to health adult's face speech, upper limb pressure: the systolic pressure of patient blood adds 50～75mmHg, lower limb pressure: systolic pressure adds 100～l50mmHg, and pressurized treatments can be arranged in the module.Medical research shows, the damage that ischemia pretreatment and ischemia post processing can alleviate limbs and amphi position organ, and the function of pretreatment and post processing can realize by delay circuit.
