Description

Phlebothrombosis control self-helping portable device
Technical field:
This utility model relates to pressure wave and magnetotherapy effect in human body to prevent venothrombotic device, is particularly suited for the deep venous thrombosis control and improves blood circulation.
Background technology:
Clinically, often can be observed, experience operation, anesthesia and prolonged lie up and other loses the people of mobility, if any malignant disease, paraplegia or quadriplegia, be in patients such as lethargic state, perhaps be in the healthy people that seat standing for a long time state of a specified duration is unable to stir any more for a long time, as aerial long-distance travel etc., a kind of symptom that is referred to as deep venous thrombosis can take place, this be a kind of in both legs and pelvic area the thromboembolism of deep vein liquid.This thromboembolism is to transport venous blood owing to lack leg muscle motion pump, or the local vascular damage, or sticking too high the causing of lower body blood.Often find in clinical,, tend to cause " pulmonary infarction ", cause " sudden death " if a thrombosis is moved to pulmonary by the dark vein of shank; Perhaps disturb the cardiovascular blood circulation, its symptom also is enough to cause life danger.
On physiology essence, one of human cost of being paid for walking upright is exactly to suffer from varicose veins of the lower extremity easily, causes that the inefficacy of veins of lower extremity medium-sized vein lobe, blood flow slow down, stasis.Expand owing to the increase of the rising of progesterone level and blood volume also can make the veins of lower extremity wall loosen in women period of pregnancy.This class symptom for a long time just forms deep venous thrombosis easily.
Eliminating or preventing the method for above all symptoms is to keep blood flow unimpeded.Blood flow not only needs heartbeat, also needs muscle contraction, because shank has been concentrated human body muscle over half, old friend's body lower limb play the important function of " second heart ", also should demonstrate,prove " people is old, and lower limb declines earlier " phenomenon of the normal meaning of people.
Therefore in clinical or some specific living environment, come the blood circulation promoting, very be necessary the generation and the development that utilize some supplementary meanss to prevent, control this class disease, even reach the purpose of improving with treatment except utilizing medicine.
Know that now as the important measures of so-called " the slow therapy of pressing " clinically, above-mentioned these symptoms can be controlled or alleviate by applying mode that clearance pressure patient Yu both legs promote its blood circulation (venous return).One piece of early stage paper that can bring to court is " the extraneous air intermittent pressure to human body in Fibrinolytic effect (External Pneumatic Intermittent Compression on Fibrinolysis in Man) " that Allenby etc. delivers on 22 days TheLancet of December in 1973 (lancet).The author finds that patient's common its body inner fibrin dissolving after operation can be suppressed, and can stimulate fibrinolysis in the air pressure in its shank effect gap.The author reaches a conclusion by experiment, and the air pressure of doing on shank after patient's average of operation periods reaches in order to the gap is the safe and effective method of prevention patient's postoperative phlebothrombosis.
In addition, from the hemorheology angle, there is the blood of viscosity to have only as its suffered shear stress Shi Caihui that acquires a certain degree and has the effect of shear thinning; For quiet stagnant blood in the dark vein that is embedded in the shank depths, especially need higher shear action, just can make its flow activation.And vein blood vessel has the physiological characteristics of unidirectional lobe, make keep its blood mediation also need higher along vessel axis to shearing force.
But more existing the utilization in the technical scheme that portable air pressure comes prevention of deep vein thrombosis owing to be subjected to the limitation of the airbag structure that proposed, only utilized the pressure at right angle effect of swelling gasbag to the body surface position.As the self-helping portable pressure apparatus that is proposed in the calendar year 2001 JIUYUE 18 days laid-open U.S. Patents (U.S.Pat.No.6290662), its dull pressure at right angle effect caused a kind of may consequence be in dark vein and the superficial vein viscid blood only between two or several venous valves back and forth, be difficult to cause effective biological blood flow shearing pulsation in the dark vein, do not reach the abundant circulation purpose of blood flow, even poor effect.And because of its monoblock type air bag volume is big, causing being full of air, to reach persistent period of scheduled pressure value long, is unfavorable for very much pressure is done realization as multiple mode flexible purpose.
In addition, magnetic stimulates the confirmation that has also obtained many documents for the effect of the muscle nerve at the many positions of human body, for the magnetic stimulating effect of leg muscle nerve direct evidence is arranged also.At disclosed patent U.S.Pat.6 on April 10 calendar year 2001, show that as California, USA VernonWen-Hau Lin magnetic stimulates that dissolving has significant facilitation with endogenous fibrinolysis to the human whole blood blood clotting in 213,933.And point out, can stimulate in its body neural by the inductive electric current in variation magnetic field, as shank fibula and tibia nerve, cause leg muscle group's spastic contraction, thereby cause significant fibrinolysis, and the obvious effective prevention that very helps deep venous thrombosis of the lasting enhancing of fibrinolytic activity in the blood.But in the seen up to now technical scheme, the utilization of magnetic stimulating effect is not of portable form, and what implement the stimulation of human body surface magnetic in the as noted above patent is bigger work top; Do not see with the coupling of vapour-pressure type acting device yet and strengthen the prevention of deep venous thrombosis and the technical scheme of therapeutic effect.
Therefore, the seen so far device that plays similar functions, no matter whether portable, they play a limited reason of effect is that they are used for preventing the intensity of this symptom and effect level suitably not to satisfy physiology feedback characteristics between dark vein and nervus peripheralis thereof and the muscular tissue to a great extent, the function mode dullness of various devices, the effect that has or even unsuitable; And the portable degree of so-called " portable mode " also is restricted greatly because of the unit useful effect required air volume of designed airbag structure.
Thereby, for prevention and control deep venous thrombosis and relevant blood circulation symptom, need to develop the portable self-aid type device of more effectively regulating dark vein physiological pulse function in practice.
Summary of the invention:
Improve with blood circulation in order to overcome existing deep venous thrombosis prevention that pressure effect is difficult to affact effectively deep vein and the single deficiency of regulative mode in the body in the portable self-auxiliary device, this utility model provides the self-helping portable device of a kind of phlebothrombosis prevention with control, this device can not only produce and close the fluctuation formula pressure permeation effect that the dark vein normal physiological pulsation of symbol needs, and have the multiple effect of pressure flexibly regulative mode, also have magnetic stimulation simultaneously to target site.
