Description
Technical field
The utility model relates to medical instruments fields, are more specifically a kind of ankle pumps, can prevent lower limb vein thrombus, lower limb
Muscular atrophy and articular ligament contracture facilitate the symptom and sign for improving venous return obstacle disease, and to ankle-joint function
It can restore to play an important role.
Background technique
Venous thromboembolism is the third-largest acute cardiovascular event come after acute coronary syndrome and apoplexy, dead
Rate may be up to 20%, mainly caused by the pulmonary embolism caused by lower-limb deep veins thrombus falls off, in addition, Lower limb deep venous thrombosis
There are about 30%~50% in patient to develop into Deep vein post-thrombosis syndrome, causes the pain that patient is long-term.Deep veins of lower limb blood
High lethality rate, the high disability rate of bolt seriously threaten life and health, create a huge challenge to public health, and overall incidence is presented
The trend of liter.
Classical theory thinks that tunica intima of vein damage, high blood coagulation state and slow blood flow are the three big of Deep vain thrombosis
Factor.The easy hair factor of deep vein thrombosis includes advanced age, wound, surgical operation, malignant tumour, varication, cardiovascular and cerebrovascular disease
Disease etc., wherein being clinically most worth pass because many factors bed rest time such as advanced age, wound, operation, underlying disease is longer
The factor of note.Currently, China has become the most country of elderly population in the world and aging of population is with the fastest developing speed
One of country, the morbidity of bring relevant to old-age group, cardiovascular and cerebrovascular disease etc. lower-limb deep veins thrombus and pulmonary embolism therewith
Several risings.Therefore, extremely important for the prevention of lower-limb deep veins thrombus, there is deep medicine and social effect.
The prevention method of lower-limb deep veins thrombus includes two kinds: Drug prevention and mechanicalness prevention.The pre- tetrandra root of Drug
Through be proved can effectively pre- preventing thrombosis generation, but the risk of bleeding is also brought simultaneously, after serious person may occur in which peritonaeum
Hemotoncus, cerebral hemorrhage or even threat to life, moreover under the treatment of the Prophylactic anticoagulation of standardization, still have and deep veins of lower limb blood occurs
The possibility of bolt.Mechanicalness prevents to avoid the risk of bleeding, safer, comfortable, and has obtained promoting well, at present clinically
Frequently with physical therapy modalities such as intermittent inflating pressure pump, the pump movements of vola arteriovenous pump therapeutic equipment, ankle, while using and raising
Lower limb wear the assisted cares measures such as anti-bolt stretch socks, lower limb muscles massage.
Intermittent inflating pressure pump is the widest mechanicalness preventive means of current clinical application both at home and abroad, i.e., with full-automatic
Sequential pressurization inflator pump auxiliary lower limb vascular reflux, is equivalent to since foot, a soft extruding from bottom to top, promotes distal end
Blood and lymphatic return.But this mode belongs to passive movement, only squeezes patient muscle, and lower limb muscles are not
Activity, therefore the muscular atrophy and articular ligament contracture of sickbed patients can not be prevented.There are the surface of a wound, fresh operation for lower limb
Situations such as notch, is not particularly suited for this method, has certain limitation.Arteriovenous enough pump be imitate plantar venous grow thickly reason effect

Add returned blood volume, promotes the Efficient Cycle and arteries function of lower limb arteriovenous blood.Its drawback and intermittent inflating pressure
Pump it is identical, patient's lower limb muscles there is no activity, the muscular atrophy and articular ligament contracture of sickbed patients cannot be prevented.
Ankle pump movement is exactly by the maximum dorsiflexion of ankle-joint, plantar flexion movement and maximum varus and (ring turns) fortune of turning up
It is dynamic, to promote the blood circulation and lymphatic return of lower limb.When plantar flexion, i.e. downward pointed toes, triceps are shunk, while shin bone
Preceding flesh diastole；When dorsiflexion, i.e. upward hook point, triceps diastole, while tibialis anterior is shunk.Leg muscle is especially small
There are venous sinus, these intravenous blood almost only by the centripetal reflux of effect ability of muscle pump, to lie on the back for leg triceps
When such case it is more prominent, the contraction of muscle can squeeze capillary abundant therein (" about more than 500 root capillaries
Be present in the muscle of every mm section "), lymphatic vessel, promote blood, lymph reflux emptying；Muscle diastole, blood
Liquid lymph flows into again.The movement makes muscle work as pump, effectively facilitates the blood circulation of entire lower limb, changes length
The stasis of blood stagnant state of lower limb venous blood when phase lies in bed, to achieve the purpose that prevent lower-limb deep veins thrombus.In addition, ankle pump movement can

Contracting and articular ligament contracture.Patient with side quadriplegia is pumped by ankle and is moved, can be prevented to a certain extent
The only atrophy of gastrocnemius and ankle muscle pulls the heel string and associated ligaments of contracture, avoids the stiff of ankle-joint, effectively prevents
Drop foot.
Ankle pump movement is a simple, safe, easy exercise method, and activity is small, in addition to the operation of ankle-joint itself
Other than cannot practicing, as long as foot does not have the fixation of gypsum etc, it can start to practice.It is poor for patient compliance or because
In the case that the factors such as limbs disturbance are unable to the movement of complete independently ankle pump, nursing staff is difficult to ensure effectively cooperation, need
Artificial ankle pumping unit cooperative movement patient's ankle-joint, to reach the medicine prevented lower-limb deep veins thrombus, prevent muscular atrophy etc.
Purpose.Have studies at home and abroad show that, the movement of the ankle of either active pump or passive movement can reach same purpose, and
And the two compares no marked difference.
Clinically prevent the mechanicalness preventive means of lower-limb deep veins thrombus at present still with intermittent inflating pressure pump, vola
Based on arteriovenous pump therapeutic equipment etc., although many document reports effectively improve veins of lower extremity flow velocity and have good prevention quiet
The effect of arteries and veins thrombus, but it is higher for incidence caused by lying in bed, to influence the restorative lower limb muscles atrophy of patient, joint tough
Band contracture etc. is but without being helped.Either the ankle of active pumps movement, and still passively artificial ankle pumping unit application, is effectively preventing
While lower limb vein thrombus, the deficiency of above equipment functionally is overcome.In addition, arriving and heart and brain blood with aging society
The rising of pipe disease incidence, so that bed or handicapped patient populations significantly increase in family, lower limb in nursing process
Functional training it is critically important, but need a large amount of manpower, lack that cheap, design is simple, effect on medical market again at present
It is good for lower limb function take exercise small device, with prevent lower-limb deep veins thrombus, prevent or mitigate lower limb muscles atrophy,
The complication such as articular ligament contracture, drop foot.
