Description
Technical field
This utility model relates to medical apparatus and instruments, particularly one adding pressure type veins of lower extremity auxiliary reflux air bag piecemeal, for prevention and the backflow of auxiliary treatment veins of lower extremity not freely or thrombosis.
Background technology
Deep veins of lower limb is the main thoroughfare of lower limb vascular backflow.Deep venous thrombosis of lower limbs refers to and define thrombosis in this passage.Its harm causes lower limbs edema except vein obstruction backflow, destroys outside the 26S Proteasome Structure and Function of veins of lower extremity and valve, if thrombus breaks loose, lung can also be caused to block and cause patient to be difficult to the sudden death of rescuing.Deep venous thrombosis of lower limbs has become the domestic and international commonly encountered diseases of harm people health.Slowly even stopping of intravenous blood flow rate is thrombotic one of the main reasons.Normal person impels veins of lower extremity blood backflow by the motion of shank gastrocnemius, and gastrocnemius also hence obtains one's name as calf muscle pump.Patient and some of some long-term beds keep the people of same attitude inertia lower limb for a long time, very easily form deep vein thrombosis of lower extremity or varicose veins of the lower extremity owing to lacking the effect of calf muscle pump.Generally use at present both at home and abroad medicine or mechanical prevention and auxiliary treating method.In mechanicalness prevention and auxiliary treating method, clinically to sickbed patients many employings lower limb lifting to promote venous backflow, and adopt active measure, allow patient use foot and ankle movement apparatus in bed, to strengthen the effect of calf muscle pump.Also has the measure of some passive types, as strong elastic stocking, the massage of lower limb air bag pressure etc.Though these measures can play some effects, the comparatively trouble had during use, what have makes patient very uncomfortable, the measure of some especially described passive types, applies entirety and carries out extruding massage with equal pressure, patient is agonized and produces little effect lower limb.Therefore, necessary invention one is used for prevention and the not smooth or thrombotic device of auxiliary treatment veins of lower extremity backflow.
Summary of the invention
For above-mentioned situation, for solving the defect of prior art, the object of this utility model is just to provide one adding pressure type veins of lower extremity auxiliary reflux air bag piecemeal, effectively can solve the not smooth or thrombotic problem of veins of lower extremity backflow.
The technical scheme that this utility model solves is, comprise fan-shaped air bag and main frame, fan-shaped air bag prolongs radial direction and is divided into several adjacent and each self-enclosed segmentation air bag, pressure check valve is provided with between each segmentation air bag, one end of lowermost air bag is provided with air inlet, air inlet is connected with compressed-air line, pressure transducer is provided with in uppermost air bag, the holding wire of pressure transducer is stretched out by air bag one end, leakage port is provided with in one end of each segmentation air bag, leakage port is externally connected with miniature electromagnetic valve, all miniature electromagnetic valves are all parallel to lose heart and perform circuit, lose heart and perform circuit, compressed-air line, holding wire is all connected with main frame.
Some passive type measures that this utility model effectively overcomes prior art apply the overall defect carrying out extruding massage with equal pressure to lower limb, circularly pressing massage is added to lower limb from the bottom up, to promote veins of lower extremity blood backflow, be prevention and the innovation of auxiliary treatment veins of lower extremity backflow freely or on thrombosis device.

Fig. 2 is main frame internal circuit annexation schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1-2, this utility model comprises fan-shaped air bag and main frame, fan-shaped air bag 1 prolongs radial direction and is divided into several adjacent and each self-enclosed segmentation air bag, pressure check valve 4 is provided with between each segmentation air bag, one end of lowermost air bag is provided with air inlet, air inlet is connected with compressed-air line 5, pressure transducer 8 is provided with in uppermost air bag, the holding wire 8a of pressure transducer 8 is stretched out by air bag one end, leakage port is provided with in one end of each segmentation air bag, leakage port is externally connected with miniature electromagnetic valve 7, all miniature electromagnetic valves 7 are all parallel to lose heart and perform circuit 6, lose heart and perform circuit 6, compressed-air line 5, holding wire 8a is all connected with main frame 9.
In order to ensure result of use, described main frame 9 is made up of micro air pump 11, controller 12 and power supply 13, micro air pump 11, the execution circuit 6 that loses heart, holding wire 8a are all connected with controller 12, and compressed-air line 5 is connected with micro air pump 11, and controller 12 is connected with power supply 13.
Described controller is cyclelog or 8051 singlechip controllers.
The flow of described micro air pump is 0.5-3L/min, and the operating pressure of fan-shaped air bag is 180-280mmHg(24 kPa-37 kPas).
The both sides of described fan-shaped air bag 1 are provided with velcro 2, and the matte limit 3a of velcro 2 is wider than limit, hook side 3b.
Described disappointing execution circuit 6, holding wire 8a, compressed-air line 5 are set with flexible pipe 10, and are placed in 3a side, matte limit.
Service condition of the present utility model is, fan-shaped air bag is wrapped in patient's lower limb (such as shank, this product can certainly be extended a part to thigh), by both sides velcro fastening, power up to main frame and start, air pump is first inflated lowermost gasbag pressurizes, when lowermost air bag reaches certain pressure, pressure check valve opens ventilation, adjacent cells starts pressurization inflation, inflation of upwards pressurizeing successively like this, when uppermost air bag pressure reaches certain pressure, pressure transducer sends signal feedback to controller, namely controller sends disappointing executive signal to each gas bleeder valve, close air pump simultaneously, this state delay for a moment, gas bleeder valve cuts out, air pump starts, circulation like this is until Host Shutdown.Controller can regulate air deflating state delay duration and aeration gas flow flow, and main frame arranges knob, and medical personnel or patient select suitable numerical value by the knob on main frame.
This utility model segmentation air bag inflating pressure piecemeal from lower to upper, really serves auxiliary veins of lower extremity blood and upwards runs, reach the effect of normal reflow.Simultaneously; this utility model structure is simply light and handy; new reasonable; main frame also can realize miniaturization; therefore can carry with, without requiring patient's bed, patient can carry out some normal activities; be the innovation that prevention and auxiliary treatment veins of lower extremity reflux on not smooth or thrombotic device, there is good economic and social benefit.
