A kind of hemostasis instrument with heat abstractor

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 heat abstractor 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 heat abstractor of pretreatment and post-processing function is provided.

The realization the technical solution of the utility model is: a kind of hemostasis instrument with heat abstractor, it is characterized in that: comprise tourniquet, box body, circuit board, circuit board and heat abstractor are housed in box body, and described heat abstractor comprises aluminium base and is fixed in the aluminum thermal fin of aluminium base; Described aluminum thermal fin comprises a plurality of radiating fins, and described radiating fin surface is provided with nickel coating, is provided with the stannum layer between described radiating fin and the aluminium base, and described radiating fin and aluminium base weld together by the stannum layer; Described radiating fin can be arranged to be fit to cross-ventilated shape according to the needs of circuit board, makes radiating surface more, and it is faster to dispel the heat; The radiating fin of nickel plating and aluminium base weld together by the stannum layer, and the welding of aluminium base and aluminum thermal fin is tightr, have solved the difficult problem that aluminum thermal fin can't weld in the traditional handicraft, and this construction for heat radiating device is simple, and heat conductivity is stronger, and radiating effect is better; Radiating fin is provided with nickel coating outward and has also played anticorrosion, anti-oxidation effect; 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.
