Description
Technical field
The utility model belongs to Bioexperiment device technical field, is specifically related to a kind of saliva collection and saliva liquid volume measurement device.
Background technology
The research of salivary secretion is the fundamental research for salivary gland function, also relates to physiology of oral cavity, biochemistry, microorganism and the multi-disciplinary fundamental research such as clinical.Saliva collection is divided into the saliva collection of full saliva collection and single body of gland, conventional full saliva collection method has fine-still method, tell follow the example of, attraction method, swab stick method four kinds, wherein attract method and swab stick method can produce the stimulation of certain degree to oral cavity, thus the saliva amount of experimenter is had an impact, therefore now do not advocate.
The test tube of fine-still method normally experimenter's hand held tape funnel, makes saliva instill gradually in test tube along lower lip, at the end of experimenter saliva in mouth is all spat in test tube; Tell that to follow the example of be that experimenter makes saliva assemble at the bottom of mouth, the saliva of gathering spits in the test tube of band funnel every 60s or certain hour by experimenter.These two kinds of collection methods all need the test tube using band funnel, but find in actual tests, because saliva viscosity is larger, when off-test, funnel is still attached with more saliva and cannot falls into test tube, especially when (as every min) collects subjects saliva needs at times, because saliva amount per minute is limited, saliva residual on funnel has a significant impact the metering that saliva is measured.Such as, find in experiment, when experimenter spues 1 milliliter of saliva, the saliva having hundreds of microlitre attaches because viscosity is excessive on inner wall of hopper, cannot flow in test tube.And when testing often to saliva amount have individual lowest limit requirement, therefore, for up to nearly 50% saliva collection process losses, experimenter and experimenter all wish improvement.
At present, the object of existing saliva collecting device is generally only and gathers a certain amount of saliva and detect, or the saliva memory storage designed for paramedic, and not having can the device of accurate-metering saliva amount.
The problems referred to above are solved by the technical solution of the utility model.
Utility model content
The purpose of this utility model is to provide a kind ofly can collect the thick liquids such as saliva and the device of its volume of accurate-metering easily.
The utility model relates to a kind of saliva collection and saliva liquid volume measurement device, and it comprises the silica gel funnel 3 that the outer tube 1 of socket and interior pipe 2 and top can fold; Can enter in described interior pipe 2 after wherein said silica gel funnel 3 top is folding, the coboundary of described interior pipe 2 is stuck on the coboundary of described outer tube 1, the bottom of described interior pipe 2 has confession saliva 8 and passes through and fix the spacer screen 7 of described silica gel funnel 3 bottom conduit, the sidewall of described outer tube 1 has volume markings and is connected with lid 5 by the band 6 that is flexible coupling.Preferably, the described outer tube 1 of this device itself is centrifuge tube.
In the preferred technical scheme of the utility model, the bottom conduit bottom opening of described silica gel funnel 3 is angle.
In the preferred technical scheme of the utility model, the lower guide inside pipe wall of described silica gel funnel 3 is added is provided with cross frame 9, described cross frame 9 is fixed with the pull bar 4 leading to described silica gel funnel 3 top.Moving up and down of described silica gel funnel 3 is convenient in acting as of wherein said pull bar 4.
In the preferred technical scheme of the utility model, the bottom conduit outer wall of described silica gel funnel 3 is provided with the projection 10 that can be stuck on described spacer screen 7.
The utility model achieves following beneficial effect:
Saliva collection of the present utility model and saliva liquid volume measurement device can collect saliva or other thick liquids easily, and can whole device centrifugal together, avoid saliva and be attached to that silica gel inner wall of hopper causes cannot the drawback of accurate-metering, by after centrifugal can the enrichment saliva of collecting to carry out follow-up detection.And described outer tube 1 sidewall of this device has volume markings, directly can determine the volume collecting saliva; On the other hand of poor quality by what measure that the utility model device collects before and after saliva, also accurately can determine the quality of collecting saliva.Device of the present utility model can reduce the contaminated chance of saliva in saliva collection and saliva liquid volume measurement process, guarantees that saliva sample undergoes no deterioration in collection process, improves and collects quality; Directly determine saliva volume, reduce operation steps, reduce experimental error.
