Abstract
The present invention relates to the novel Medical Instruments of a kind of promotion venous blood circulation, its action principle is: the pulse compressed air that is produced by instrument is transported to and twines in the airbag that spreads on affected part, and affected part is formed periodically extruding, impels venous blood flow to quicken, strengthen blood circulation, this instrument purposes is as follows:
1. it is stagnant that treatment fracture, joint replacement, blood vessel postoperative or long-term bed cause the not smooth caused vein of venous return to be stopped up, diseases such as venous thrombosis;
2. can prevent or treat lower limb disease for the workman who is engaged in the work of standing or walk for a long time;
3. help to recover athlete's limbs vigor, fast track rehabilitation.
Description
The present invention relates to the novel Medical Instruments of a kind of promotion venous blood circulation.Its action principle is: the pulse compressed air that is produced by instrument is transported to and twines in the airbag that spreads on affected part, and affected part is formed periodically extruding, impels venous blood flow to quicken, and strengthens blood circulation.This instrument purposes is as follows:
1. it is stagnant that treatment fracture, joint replacement, blood vessel postoperative or long-term bed cause the not smooth caused vein of venous return to be stopped up, diseases such as venous thrombosis;
2. can prevent or treat lower limb disease for the workman who is engaged in the work of standing or walk for a long time
3. help to recover athlete's limbs vigor, fast track rehabilitation
Can treat the reason of multiple disease according to the Chinese traditional massage art, in conjunction with the imagination by means of instrument auxiliary treatment venous disease that China's cardiovascular specialist is brewed for a long time, the present invention conceives proposition: utilization is converted to pulsation air pressure with compressed air and simulates massage effect through the extruding of airbag formation periodicity.
Specific embodiments of the invention are as follows: use mini air compressor as producing compressed-air actuated power source, through buffering, oil-water separation, filter the decompression back and form steady air flow with the pressure that requires (50-300 millimeter of mercury), again through the rotary multichannel distributing valve of adjustable-speed, air-flow is delivered to the output gas circuit respectively successively by certain frequency,, again it is communicated with atmosphere through certain persistent period (speed that depends on rotary multichannel distributing valve).Like this, for each Lu Eryan, air-flow has become pulse state.Send into successively to twine when this pulse pneumatic and spread on the vola, ankle joint when shank, the special airbag at positions such as knee joint and thigh, has then formed periodically extruding force of relay shape from bottom to top in airbag.Go round and begin again, simulate from bottom to top massage effect with this.
Be connected by softish plastic tube or rubber tube between the gas circuit outfan of instrument and the airbag.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof:
Fig. 1 is a principle of conceiving the blood circulation aid embodiment of proposition according to the present invention, describes concrete device details and the working condition that proposes according to the present invention in detail below in conjunction with Fig. 1.
This instrument comprises an OF-93 type low noise air compressor (1) (enclosure pressure automatic interrupter), air accumulator (2), relief valve (3), Pressure gauge (4), filtering pressure reducing valve (5), rotary multichannel distributing valve (6), arrangements for speed regulation (7), trachea (8), airbag (9) and blowoff valve (10).
Fig. 2 is the structural representation of rotary multichannel distributing valve.Have five ventholes (present embodiment is five tunnel) and an air inlet (2) on the valve body (1).Spool is drilled with the duct corresponding with air inlet and venthole and steam vent and the corresponding duct of venthole.When spool drags when rotating with setting speed down at motor, air inlet just communicates with venthole successively, then, steam vent communicates with venthole again successively, so the airbag that is connected with each venthole just is in and periodically charges and discharge gaseity, thereby produce periodically extruding force.Fig. 3 is the sequential chart that extruding force appears in five airbags.
Rotary multichannel distributing valve among the present invention can also be controlled three-way solenoid valve by impulse circuit and replace.
Fig. 4 is second kind of embodiment, and source of the gas and aid system thereof are the same, the generation of the different air pressure of just pulsing by means of impulse circuit.This circuit constitutes pulsewidth and adjustable respectively at interval rectangular pulse wave producer by 555.Through counting-decoder pulse distribution is become five tunnel outputs.Drive three-way solenoid valve through power amplification element again.When rectangular wave pulse occurred, air communication was crossed this valve and is inflated to airbag, and after pulse disappeared, three-way solenoid valve resetted, and its port of export was communicated then airbag venting with atmosphere.Also can form periodically extruding force.
Model machine of the present invention is since fourth quarter in 1989, and by unit clinic trial such as the loyal hospital of peace and the State Physical Culture and Sports Commission, curative effect is rather good always, and effective percentage reaches 100%.
Fig. 4 is the airbag shape and size of treatment limbs different parts.
The technical specification of this instrument is as follows:
1. the crushing strength to affected part is about the 50-300 millimeter of mercury, decides according to patient's concrete condition
2. push frequency 0.5-2.0 time/second (adjustable)
3. noise is lower than 50db(A)
Fig. 4 is an electron type blood circulation aid schematic diagram
Air compressor (1), air accumulator (2), relief valve (3), pressure automatic switch (4), filtering pressure reducing valve (5), Pressure gauge (6), rotary multichannel distributing valve (8), three-way solenoid valve (9) airbag (10) blowoff valve (11) trachea (12)
Claims (3)
1, blood circulation aid is characterized in that: a mini air compressor, and multichannel (or single channel) gas distributing valve and control circuit thereof, and be connected with the multipath gas outfan, be used for the airbag of each one of limbs.
2, according to the described blood circulation aid of claim 1, it is characterized in that: by the pulse compressed air with the pressure that requires (50-300 millimeter of mercury) of instrument generation, be transported to and twine in the airbag that spreads on affected part, affected part is formed periodically extruding, impel venous blood flow to quicken, strengthen blood circulation.
3, a kind of non-operative treatment of utilizing automaton simulation massage effect treatment venous disease.
