Description
Technical field
The present invention relates to medical field, particularly a kind of arteriopalmus locating development piece for arteriopuncture.
Background technology
Clinical invasive vascular puncture (artery, Deep venou), is mostly by touching the specific arterial pulse in body surface specific region
Moving point and traveling carry out artery or vena comes is punctured.Due to without puncture vessel body surface objective indicator indicate, by room temperature,
Patient temperature, heart rate, blood pressure and operator's experience, finger tip thoughts and feelings, arteriopalmus interference even mood etc. of finger tip itself are more
Uncontrollable factor influence, success rate and the time-consuming very different of puncture are planted, to various method arteriopuncture success rates in document
Discussion can be found everywhere.And can as the B ultrasonic guided puncture of guiding puncture gold index it is domestic at present due to it is expensive, use shifting
The reason for dynamic inconvenience, just do not have the advantage of universalness for the medical conditions of the country at present, therefore find one it is sufficiently low
Honest and clean visualization alternative solution is extremely urgent.
The reason for studying carefully its vascular puncture and fail, slide displacement often with target arterial, beating are difficult to touch or beat more
Dissipated wide directly related.Therefore, the area of impression beating is reduced as far as possible, is reduced and is punctured scope, find optimum puncturing point and be only
The key of puncture.And the success that punctures rearmounted pipe is then out of shape closely related with blood vessel, putting pipe and avoid deformity in advance forward
Differentiated vascular is also the problem for needing to take precautions against.
The content of the invention
The invention provides a kind of arteriopalmus locating development piece with low cost, easy to use.
To achieve the above object, the technical scheme is that：
A kind of arteriopalmus locating development piece, including display device, it is characterised in that：

Conductive layer, upper alignment film, liquid crystal layer, lower alignment film, transparent dot matrix conductive layer, transparent piezoelectric film layer, lower transparency conducting layer, under
Polarized light piece and pressure sensitive adhesive coupling layer；
When arteriopalmus pressure conduction to transparent piezoelectric film layer, transparent piezoelectric film layer upper and lower surface can be produced
One electrical potential difference, then acts on liquid crystal layer upper and lower surface, electrical potential difference by transparency conducting layer on loop and lower transparency conducting layer
Electric field is formed, threshold potential is reached, you can liquid crystal molecule deflection is driven, the continuation of arteriopalmus triggers the dynamic change of potential,
Cause the consecutive variations of liquid crystal molecule deflection angle, so that light transmittance occurrence dynamics change, liquid crystal layer flashes with pressure change
Imaging, that is, form beating dot matrix imaging, depicts arteries position and trend.
Further, it is additionally provided with reflecting layer between the lower polarized light piece and pressure sensitive adhesive coupling layer.
Further, the hard transparent material layer, upper transparency conducting layer, upper alignment film, liquid crystal layer, lower alignment film, thoroughly
Bright lattice conduction layer, transparent piezoelectric film layer and lower transparency conducting layer surround a sealing fluid by the envelope frame that clear binder is made
Brilliant case structure.
Further, the side of the display device is provided with imaging needed for adjustment changes and is opened with the fine setting of the contrast of background
Close, the inching switch is linked on the bleeder circuit between transparency conducting layer and lower transparency conducting layer.
Further, the upper transparency conducting layer and lower transparency conducting layer are made up of transparent electrically conductive membrane material.
Preferably, the electrically conductive membrane material is ITO conducting films, metal film, oxidation film, polymeric membrane or composite membrane.
Preferably, the PPI of the transparent dot matrix conductive layer>300.
Preferably, hard transparent material layer is made up of glass or plastics.
The arteriopalmus locating development piece of above structure, when arteriopalmus pressure conduction to transparent piezoelectric film layer
Wait, piezoelectric membrane upper and lower surface can produce an electrical potential difference（That is piezo-electric effect）, then acted on by loop transparency conducting layer
Liquid crystal layer upper and lower surface, electrical potential difference forms electric field, reaches threshold potential, you can drive liquid crystal molecule deflection, and arteriopalmus continues
Property trigger potential dynamic change（When threshold potential is reached, liquid crystal molecule starts deflection, that is, start to show minimal gray effect,
When sticking potential is reached, liquid crystal molecule deflects into maximum angle, that is, reach maximum gray scale display effect）, cause liquid crystal molecule
The consecutive variations of deflection angle, so that light transmittance occurrence dynamics change, liquid crystal layer forms and fights with pressure change scintillography
Moving point battle array imaging, under the reinforcing contrast effect in reflecting layer, can form macroscopic real-time display image, depict arterial blood
Pipe position and trend；If cancelling opaque reflecting layer or using translucent reflective layer, perspective imaging effect is formed.In addition,
Using pressure sensitive adhesive coupling layer, it is possible to provide the effect of fixed and coupling pressure, the effect also with anti-interference and LPF.
When using, need site of puncture to fix arteriopalmus developer sheet in body surface, convenient pressure first is applied to developer sheet（Make
Press with finger with pressurization restraint device or directly）, observation development film developing, adjustment position and pressure are most preferably developed with reaching
Effect, imaging needed for changing as necessary by trim voltage adjustment and the contrast of background, reach and limit the optimal of arteriopalmus
Scope and optimized image effect, at this moment, eyes can clearly observe the arteries position flashed in real time with pulse on developer sheet
And trend, conventional artery is then carried out again or vena comes is punctured.
The present invention utilizes the pulsation of artery and is difficult pressing off property, sensitive to dynamic mechanically vibrations using piezoelectric type material
Piezoelectric property, and combine the intuitive of liquid crystal display（Liquid crystal is predeterminable for shades of colour and positive and negative display effect）, it is wound blood vessel
Puncture and a kind of cheap easily visibility solution is provided, greatly reduce mortality caused by being punctured due to blindness.This
Invention has advantages below：With low cost, volume is small, is easy to carry；Reliability is good, can intuitively observe the dynamic of pulse flicker
Arteries and veins vessel position and trend；Facilitate easy-to-use, without learning cost；Single use, can avoid cross-infection, reduce valuable ultrasound
Equipment loss and disinfection cost；Punctured suitable for the quick vim and vigour sampling of all needs, the invisible artery of naked eyes and vena comes normal
Rule use, and reduce repeated multiple times complication after puncture, are particularly suitable for clinic guidance, reduce manual operation experience error, ensure
Medical safety, has a wide range of application, and market prospects are huge.
