Description

A kind of multi-functional ankle pump

Technical field

The utility model relates to medical instruments fields, are more particularly a kind of novel ankle pumps, can prevent veins of lower extremity blood Bolt, lower limb muscles atrophy and articular ligament contracture facilitate the symptom and sign for improving venous return obstacle disease, and to ankle Joint function recovery plays 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 vein thrombosis High lethality rate, high disability rate seriously threaten life and health, create a huge challenge to public health, and overall incidence becomes in rising Gesture.

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 rising of bring lower-limb deep veins thrombus and the morbidity number of pulmonary embolism therewith.Therefore, for deep veins of lower limb The prevention of thrombus is extremely important, has 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, and making patients' financial burden.Mechanicalness prevents the risk for then avoiding bleeding, safer, comfortable, and obtains It promotes well, at present clinically frequently with objects such as intermittent inflating pressure pump, the pump movements of vola arteriovenous pump therapeutic equipment, ankle Treatment method is managed, while using lower limb lifting, wearing 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 patient's lower limb muscles are simultaneously Without activity, the muscular atrophy and articular ligament contracture of sickbed patients cannot be prevented.There are the surface of a wound, fresh operation to cut in lower limb Situations such as mouth, it is not particularly suited for this method, there is certain limitation.Arteriovenous enough pump be imitate plantar venous grow thickly reason effect It answers and a kind of manufactured clinical physical therapy apparatus, major function is extruding when passing through Walk Simulation to plantar venous clump, is increased Add returned blood volume, promote the Efficient Cycle of blood, improves patient's lower limb arteriovenous haemodynamics and arteries function.Its disadvantage End is identical as intermittent inflating pressure pump, patient's lower limb muscles there is no movable, cannot prevent the muscular atrophies of sickbed patients with Articular ligament contracture.

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, promote the blood circulation and lymphatic return of lower limb.When plantar flexion, i.e. downward pointed toes, triceps are shunk, while before shin bone Flesh diastole；When dorsiflexion, i.e. upward hook point, triceps diastole, while tibialis anterior is shunk.Leg muscle especially shank There are venous sinus for triceps, these intravenous blood are almost only by the centripetal reflux of effect ability of muscle pump, when lying on the back Such case is more prominent, and the contraction of muscle can squeeze capillary therein, and (" about more than 500 root capillaries are present in often In the muscle of mm section "), lymphatic vessel, promote blood, lymph reflux emptying；Muscle diastole, hematolymphoid liquid It flows into again.The movement makes muscle work as pump, effectively facilitates the blood circulation of entire lower limb, when changing long-term bed The stagnant state of the stasis of blood of veins of lower extremity blood, to achieve the purpose that prevent lower-limb deep veins thrombus.In addition, ankle pump movement can be enhanced down The muscular strength of the muscle such as limb tibialis anterior, quadriceps muscle of thigh, musculus soleus, gastrocnemius, biceps muscle of thigh can effectively prevent amyotrophia and joint Ligament contracture.Patient with side quadriplegia is pumped by ankle and is moved, gastrocnemius can be prevented to a certain extent And the atrophy of ankle muscle, the heel string and associated ligaments of contracture are pulled, the stiff of ankle-joint is avoided, effective pre- ankle-joint support.

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, still passively ankle pumping unit application, in effectively prevention lower limb While phlebothrombosis, the deficiency of above equipment functionally is overcome.In addition, with the arriving and cardiovascular and cerebrovascular disease of aging society The rising of sick disease incidence, so that bed or handicapped patient populations significantly increase in family, the function of lower limb in nursing process It can take exercise critically important, but need a large amount of manpower, lack that cheap, design is simple, works well on medical market again at present For lower limb function take exercise small device, to prevent lower-limb deep veins thrombus, prevent or mitigate lower limb muscles atrophy, joint The complication such as ligament contracture, drop foot.
