Description

Fluid sample sample detecting cup

Technical field

The utility model relates to a kind of fluid sample sample detecting cup that is used for, and belongs to disposable medical pick-up unit field.

Background technology

Existing medical sampling cup is generally flat cylindric cup, only has the function of contain fluid sample, does not have lid, and sample flows out the pollution that causes surrounding environment outside the cup easily when storing; Cup does not have the sample size sign, thereby causes sampling person's capacity when sampling to differ, and influences laboratory personnel's chemical examination work; After needing during use to draw sample liquid, carry out test paper again and measure, operate easyly inadequately, the situation that sample flows out the pollution surrounding environment also takes place when sampling simultaneously easily with suction pipe.All above-mentioned shortcomings all can cause the testing inconvenience, testing result is inaccurate and validity is poor.

Summary of the invention

In order to overcome above-mentioned shortcoming, the present invention realizes by the following method.

Fluid sample sample detecting cup is made up of cup, the bowl cover and the test strip that have rotation sampler and convex lens.

The transparent cup of cylinder type, it is cylindric that wall of cup is, and the cup end, become inverted cone-shaped structure, and this purpose of design is that the amount of working as sample plays the effect that compiles after a little while.The minimum point of back taper bottom is equal with the bottom of cylindric wall of cup, the upper limb of back taper bottom links to each other with cylindrical wall, and an outstanding structure arranged, post the temperature detection label on the cylinder outer wall at outstanding structure place, thereby the temperature of sample is determined the credibility of sample in can measuring cup.Be carved with MIN line and MAX line on the cylinder, and on the temperature detection label along the line below the MIN line, the MIN line is represented the minimum volume of this cup contain fluid sample, and the MAX line is represented the maximum volume of the sample that this cup can hold, and the height of sample liquid level should be between two lines when sampling detected.

The bowl cover that is harmonious with the transparent cup of cylinder type is to be assembled by a rotation sampler and a structure that has convex lens and rotary handle.The rotation sampler is to be formed by two close parts nest of structure.Each parts all is made up of with a hollow cylinder that is connected with lid the lid of a circle, detailed is described below: there is a hole in lid central authorities, be connected with a hollow long cylinder identical below the hole with pore diameter size, hollow long cylinder upper end directly is connected with the circular hole that covers, lower end closed, cylinder sides respectively has an aperture up and down, and lower end aperture effect is to absorb fluid sample, is called sample holes, top aperture effect is to regulate hollow cylinder inside and outside differential pressure balance, is called equalizing port.Two parts one on the other, can be described as upper strata parts and lower part according to their mutual positions, the hollow cylinder external diameter of upper strata parts is identical with the hollow cylinder internal diameter of lower part, can insert from covering the circular hole of lower part, in the nested closely cylinder that advances lower part, and can rotate, after two parts nest were intact, two apertures of upper strata parts tube side can be communicated with two apertures of lower part tube side respectively when rotating to the appropriate location.The lid of lower part matches with cup, after detecting the correct assembling of cup quilt, the level height of sample holes is below the MIN of cup line, the cylinder of upper strata parts is nested in the cylinder of lower part, the below of upper strata part covers and lower part lid top are close to, be placed into one or more supporting detection test paper in the cylinder of upper strata parts simultaneously, test strips is " " type, its vertical end that inserts in the tube is the imbibition end, length is just pushed up the bottom of upper strata parts cylinder, one end of level is a display end as a result, lain on the dome of upper strata parts, the MAX line of detection test paper and the MAX line of cup are in same level height or be higher than cup MAX line, when putting into many test strips, do not overlap between the vertical end of each test strips is mutual, horizontal ends is then put on the dome of upper strata parts radially.On the lid of upper strata parts the structure that has convex lens and rotary handle can be installed.Convex lens can be adjusted to test strips directly over, effect is the colour developing situation that can clearly see test strips.The effect of rotary handle is can be used to drive the upper strata parts rotate on lower part, changes the connection situation of two parts sample holes and equalizing port.

Lid of the present utility model both can prevent that sample liquid from flowing out the pollution surrounding environment, can carry out detecting operation by rotation again; MAX line on the cup and MIN line are determined the amount of sampling, and the temperature detection label is affixed on below the external wall MIN of the transparent cup line, thereby the temperature of measuring samples is determined the credibility of sample.Test strips is placed in the hollow long cylinder of lid upper strata parts, do not need to draw sample liquid during use and carry out test paper mensuration with suction pipe, make things convenient for laboratory personnel's chemical examination work, also avoided simultaneously the sampling operation complexity, easily polluted, and the easy sample that takes place flows out the situation of polluting surrounding environment in operating process.This sampling cup can prevent the cross pollution of sample room, guarantees the accuracy and the validity of detection, has overcome the various defectives of sampling cup commonly used at present.

Concrete performance

The utility model is by being made up of cup (1), the bowl cover and the test strip (11) that have rotation sampler and convex lens (13) as we can see from the figure.Wherein bowl cover comprises by the nested rotation sampler of forming with lower part (15) of upper strata parts (16) and structure (17) two parts that have convex lens (13) and rotary handle (14).Upper strata parts (16) are close with lower part (15) structure all to be made up of separately dome (6), (7) and hollow cylinder separately (8).

Detect the original state of cup at this, lower part in the bowl cover sampler (15) and upper strata parts (16) equalizing port (9) on the hollow cylinder sidewall and sample holes (10) separately are not communicated with, when filling fluid sample in detecting cup, sample can't arrive in the cylinder of upper strata parts and detect test paper and contact.

The sample surveyed such as blood sample or urine sample are placed cup, liquid level requires to be higher than MIN line (5) but must not surpass MAX line (4), can record the temperature of sample by the temperature detection label (3) on the outstanding structure (12) that is attached to (2) top at the bottom of cup (1) back taper, thereby determine the credibility of institute's sample product, if the blood sample of surveying or the urine sample temperature is low or the authenticity of the sample that Gao Zeke gets the scene throws doubt upon, confidence level is poor.

After having got sample and checking that temperature is determined its credibility, use rotary handle (14) rotation lid upper layer part part, the sample holes (10) and the equalizing port (9) of upper strata parts and lower part are communicated with respectively, fluid sample in the cup will flow into by the passage that two sample holes form in the hollow cylinder (8) of upper strata parts and contact with the detection test paper, and the passage that equalizing port (9) forms plays the effect of equilibrium air pressure, the liquid-adsorption layer that detects test paper (11) begins to absorb sample liquid and utilizes capillarity to move up, can pass through convex lens (13) behind the certain hour and observe the colour developing of test strips colour developing end, and detect the instructions contrast result of determination of test paper with all.
