CN202637425U - Venous thrombus prevention and treatment instrument - Google Patents

Abstract

The utility model provides a venous thrombus prevention and treatment instrument through which the objective of preventing and treating venous thrombus can be achieved mainly in a manner that four electronic air pumps are controlled by a one-chip microcomputer to pump up and blow off intermittently at a specific frequency so as to act upon arms and legs or two legs through cuffs. The main characteristics of the venous thrombus prevention and treatment instrument are that: a circuit board is fixed inside of a machine case; the four cuffs are fixed at proper positions of the arms and legs; cuff air-pipe plugs are inserted into outer interfaces of the air pumps; and after the adjustment of all parameters is finished, an operating key can be pressed to initiate the venous thrombus prevention and treatment instrument.

Description

A kind of phlebothrombosis control instrument

Technical field

This utility model provides a kind of can prevent the venothrombotic instrument of extremity.It is by Single-chip Controlling, and it is simple to have principle, and cost is low, practical characteristics, and the working mechanism by the natural anti-bolt of simulation human body can prevent the venothrombotic generation of patient bedridden in long term extremity.

Background technology

At present, clinically for peri-operation period and paralytic, still there is not a kind of simple effective method to prevent the venothrombotic generation of extremity, now adopt oral or infusion anticoagulation, promoting blood flow and remove blood stasis drug, these method oral results are not good more, and side effect is large, the transfusion cost is high again, and be systemic administration, can suppress the coagulation function of human normal, should not use the patient that bleeding tendency is arranged; And existing working method artificial or mechanical assistance activity limbs just makes the muscle passive activity, though certain effect is arranged, complex structure, cost is not very little, and is also inapplicable to some patient; The mode that the electrode in vitro stimulated muscle is shunk, not only complex structure also produces burn easily, and the complication such as arrhythmia are brought out in electric leakage, and practicality is little.Therefore clinically in the urgent need to a kind of can effectively pre-preventing thrombosis occur method.

Summary of the invention

At present there is no clinically the method that can prevent at lower cost the extremity venous thrombosis in order to overcome, this utility model not only can overcome the above problems fully, and because its working method is simple, has no side effect.Below be know-why and embodiment.

The human body lower limbs venous blood heart that refluxes smoothly ensures by three kinds of mechanism, a suction power that produces for the right ventricle diastole, and two shrink the motive forces that diastole extruding vein blood vessel produces for lower limb muscles is interrupted, title muscle pump, the three check valve effects of playing for venous valve.The third mechanism is very effective, but will have muscle pump to cooperate, disappears such as muscle pump power, blood backflow can be very slow, the special construction of venous valve can make its subregion blood flow be tending towards stopping, and becomes thrombotic source, in case a small amount of thrombosis is arranged, can as snowball, enlarge rapidly, if patient's out-of-bed activity soon after just having formed, under muscle squeezes vein and blood flow acceleration, thrombosis comes off easily, enter pulmonary artery and form pulmonary infarction, the sudden death of severe patient entail dangers to life.The formation of above pathological process, core are exactly the disappearance of muscle pump effect.

Based on above mechanism, this utility model is by repeatedly pushing limbs interruption impressed pressure and loosening vein with the simulate muscular pump, recover the human normal physiological function and avoid the generation of these complication, concrete scheme be exactly easily produce venothrombotic limbs proper site around on and similar cuff on the common sphygomanometer, act on simultaneously limbs with the Single-chip Controlling EAP Electronic Air Pump through cuff, be interrupted with certain frequency and inflate and exit, the simulate muscular systolic and diastolic function, thus reach the venothrombotic purpose of control.The additional benefits of the machine is that limbs need not produce motion, is applicable to various types of patients.

The beneficial effects of the utility model are, function by feasible simulation human body natural muscle pump, thereby repeatedly inflate and exit indirect extrusion and loosen vein with air pump and reach and prevent thrombotic effect, simple in structure, can directly reequip with existing equipment, R ﹠ D Cost is few, is that other means can not be compared at present.

Description of drawings

Below in conjunction with accompanying drawing this utility model is further specified.Fig. 1 is the profilograph of this novel embodiment, 1 shell wherein, 2 fixed screw holes, 3 circuit boards, 4 Single-chip Controlling unit, 5 control panels, 6 air pumps, 7 air pump external tappings, 8 power subsystems, 9 power lines; Fig. 2 is the control panel top view, 1 frequency display screen wherein, 2 air pressure adjustment buttons, 3 air pressure display screens, the 4 pressurization times of loosening were compared display screen, 5 pressurizations are loosened the time than regulating key, 6 job keys, 7 on and off switch, 8 frequency adjustment buttons, 9 air pump selection keys, 10 intervalometer display screens, 11 intervalometer buttons.

The specific embodiment

Circuit board is fixed in the cabinet, circuit connects, connect with the mains, open switch, cuff is fixed in the venothrombotic limbs proper site of easy generation, and cuff trachea plug inserts the air pump external tapping, and the maximum pressure that regulates frequency, timing, different air pumps loosens the time ratio with pressurization, can be by job key work, the bad or uncomfortable size that can repeatedly regulate corresponding air pump relevant parameter of user such as effect.

Claims (1)

1. A kind of phlebothrombosis control instrument, it is characterized in that: circuit board is fixed in the closed case, is electrically connected with EAP Electronic Air Pump, and four cufves are fixed in the correct position of extremity, and cuff trachea plug inserts the air pump external tapping
