Description
Technical field
This utility model relates to a kind of medical ultrasonic testing fixture, and specifically, this utility model relates to the auxiliary pressue device of a kind of far-end limbs.
Background technology
The normal person is because vein valve function in lower limbs is good, under the naturalness or end user's construction method do not occur that tangible venous blood is counter to flow after bringing out; When anti-stream of paranormal vein of persistent period occurring after manual-induced, mean to have the venous valve functional defect.Ultrasonic examination is the not conventional medical inspection method of omnidistance degree of assessment vein valve function in lower limbs, accurately judges with the Insufficient degree of differentiation venous valve to have important value for clinical optimized choice therapeutic scheme.At present; The common method of bringing out the anti-stream of vein when artificial far-end limbs pressurization is ultrasonic examination is through the seized venal distal limbs of manual pressure, after pressurization is removed in observation; Whether seized intravenous occurs that vein is counter to flow; If then there is the venous valve functional defect in the anti-stream of vein, measures the anti-stream time simultaneously, thereby the order of severity of anti-stream is made clear and definite diagnosis according to the length of anti-stream time.But; When implementing artificial far-end limbs pressurization because not of uniform size the causing of strength of different inspecting doctor's manual pressure; Even same inspecting doctor repeatedly checks the uneven situation of exerting oneself that also exists; Make check result be easy to generate error, cause the mistake of venous valve functional defect degree is estimated and judgement.
The utility model content
When implementing artificial far-end limbs pressurization in order to overcome because inspecting doctor's compression strength difference is easy to generate the deficiency of measurement error; This utility model provides a kind of far-end limbs to assist pressue device; This device not only can provide constant compression force that limbs are pressurizeed; And can quick pressure releasing, help observing and measuring the anti-stream time.
In order to solve the problems of the technologies described above; The technical scheme that this utility model adopted is: a kind of far-end limbs are assisted pressue device; Be used for the Insufficient ultrasonic quantitative classification of human body lower limbs venous valve; Said auxiliary pressue device comprise the hollow inflatable band be connected with the hollow inflatable band and be fixed in the connecting band on the said human body lower limbs; Said hollow inflatable band is connected with inflator pump through airway, on said airway, is provided with relief valve, on said hollow inflatable band, also is connected with pressure-detecting device.
Said pressure-detecting device comprises and is located at said hollow inflatable band pressure inside pick off and the display unit that is connected with pressure transducer.
Said display unit is LED display or LCDs.
Said inflator pump is a hand air pump, and said relief valve is the three-way valve that is located between said airway and the said hand air pump, and this three-way valve has at least a port to be opened or to close.
Said connecting band is two, and an end of connecting band is connected with said hollow inflatable band, and the other end is provided with velcro.
Said hollow inflatable band adopts elastomeric material to process.
Said connecting band adopts double-layer cloth to process.
This utility model adopts technique scheme; Through the intuitive and accurate hollow inflatable band internal pressure numerical value that obtains of pressure-detecting device, make pressure index to quantize, can both provide constant compression force that human body lower limbs is pressurizeed thereby reach each inspection; The repeatability of check result is strengthened; The error of having avoided artificial pressurization to produce, accuracy of detection is higher, makes the doctor carry out quantitative classification to the venous valve functional defect accurately; And, between airway and hand air pump, relief valve is set, realize quick pressure releasing, help observing and measuring the anti-stream time.
Description of drawings
Fig. 1 is this utility model structural representation;
Labelling among the above-mentioned figure is: 1, velcro I; 2, connecting band I; 3, hollow inflatable band; 4, connecting band II; 5, velcro II; 6, pressure-detecting device; 7, airway; 8, three-way valve; 9, hand air pump.
The specific embodiment
As shown in Figure 1, a kind of far-end limbs of this utility model are assisted pressue device, are used for the Insufficient ultrasonic quantitative classification of human body lower limbs venous valve.This auxiliary pressue device comprises that hollow inflatable band 3 is with that be connected with hollow inflatable band 3 and be fixed in the connecting band on the human body lower limbs.Hollow inflatable band 3 is elongated, and inner hollow is used to charge into air, and the hollow inflatable bag has elasticity, adopts elastomeric material to process, and flexible and lower limb limbs surface fits tightly.Hollow inflatable band 3 is connected with inflator pump through airway 7, on airway 7, is provided with relief valve, is used for quick pressure releasing, on hollow inflatable band 3, also is connected with pressure-detecting device 6, is used for detecting in real time the pressure in the hollow inflatable band 3.
The pressure-detecting device 6 of this auxiliary pressue device comprises and is located at hollow inflatable band 3 pressure inside pick offs and the display unit that is connected with pressure transducer; Pressure transducer detects the pressure that obtains in the hollow inflatable band 3; Produce the signal of telecommunication and show in real time through display unit, display unit is LED display or LCDs.
The inflator pump that this auxiliary pressue device adopts is a hand air pump 9, makes easy and simple to handle.Relief valve is the three-way valve 8 that is located between airway 7 and the hand air pump 9, and pressure release speed is faster, and this three-way valve 8 has at least a port to be opened or to close, to control this port and extraneous being communicated with.
The connection of this auxiliary pressue device has two, and like connecting band I among the figure 2 and connecting band II4, connecting band adopts the double-layer cloth of good permeability to process.One end of every connecting band is connected with hollow inflatable band 3, and the other end is provided with velcro, as being located at the velcro I 1 of connecting band I 2 among the figure; With the velcro II5 that is located on the connecting band II4, the velcro fastening on the connecting band, with hollow inflatable band 3 tightens on the lower limb limbs.
