Abstract

The utility model relates to a new membrane one-step type flat-strip-shaped testing drug box, comprising a flat-strip-shaped box bottom, a flat-strip-shaped box cover and a filter membrane-a reaction membrane, wherein, the box cover is provided with four windows, window 1 is used as an inlet for testing samples, window 2 is used for displaying positive state, window 3 is used for displaying negative state, and window 4 is used for displaying reaction stop state. A filter membrane-reaction membrane connecting strip is clamped between the flat-strip-shaped box bottom and the flat-strip-shaped box cover, and the reaction membrane is respectively coated with testing sample components for displaying reference bar, and the high affinity antibody of the testing sample for displaying positive bar. When the utility model is used to test LH (luteining somatotropin) and HCG (human chorion hormone), the result can be seen in two minutes after adding urine sample. With simple structure, smart and convenient use, low cost, and convenient operation, the utility model is suitable for hospitals and individuals to use.

Description

Flat-piece testing drug box

The utility model belongs to biological chemistry appliance field.

Present test kits all is after adding test sample earlier, to treat to add successively blink different reagent again and just can finish the total overall reaction process when detecting operation, and such operating efficiency is not high, and especially the individual uses and requires an application of sample to show test results at once.Big in the prior art owing to the volume of medicine box own, subsidiary simultaneously reagent, so at first bring the inconvenient problem of carrying, also must aim at certain position that medicine closes during this external adding sample and splash into special-purpose dropper or other collection equipments, such operation also makes troubles to the user.

The purpose of this utility model provides a kind of flat bar test kits very convenient to carry, only just can draw test result fast by an application of sample (can splash into also can directly dip in the utility model and get), features simple structure is suitable for commercial novel membrane type single stage method flat bar test kits.

The utility model is finished by the following technical programs, as shown in drawings, at first design (Fig. 2) at the bottom of the medicine box of the flat bar medicine box lid (Fig. 1) and the box that matches with it, be the wringing fit structure at the bottom of making lid and box by the convex concave groove that is located at lid and box feather edge respectively, accompanying vertical bar shaped filter membrane one a reaction film linking strip (Fig. 3) at the bottom of the box and between the lid, on lid, have four windows, i.e. window 1(specimen inlet window), window 2(positive reaction display window) window 3(negative reaction display window) and window 4(reaction terminating display window).Reaction film (12) overlaps with filter membrane (11,13) mutually at the position that is positioned at window 2 and window 3, like this, sample can enter (can splash into also can directly dip in and get) from application of sample window 1 and propagate to 2,3, No. 4 window directions along filter membrane, on the reaction film at corresponding No. 3 window positions, give and being weighed by negative control with the sample to be tested bag earlier, on the reaction film at corresponding No. 2 window positions with the high affinity antibody sandwich positive thick stick of composition to be measured.Bag is labeled color so that sample is propagated so far on the filter membrane at these external corresponding No. 4 window positions, and indicating as can be known from the color that shows, course of reaction finishes.

Below engage description of drawings embodiment, to measure the short luteinizing hormone(LH of LH() and the HCG(human chorionic gonadotrophin) test kits be example.

Whole medicine box divides two parts at the bottom of lid and the box, can common plastics be material, its width is 12 millimeters, thickness is 1,25 millimeter, long vertical tongue (6A, 6B) vertically is set on both sides, lid inwall right side, the horizontal tongue of lid inwall two ends horizontally set (7A, 7B) is provided with short vertical tongue (5A, 5B) in lid inwall left side.

The long vertical tongue corresponding position of inwall right side and lid is provided with long vertical groove (9A, 9B) at the bottom of box, horizontal groove (8A, 8B) is established in the horizontal tongue of inwall two ends and lid corresponding position at the bottom of box, be in the time of above said structure can guarantee at the bottom of lid is buckled in box and closely cooperate, window 1 is set from left to right, window 2, window 3 and window 4 on lid.

With strip filter membrane one reaction film bonding jumper cramping between at the bottom of lid and the box, corresponding window 2 is a reaction film with window 3 lower positions, bag is by with a certain amount of LH and HCG composition on the reaction film of window 3 positions, and bag is by the high affinity antibody with anti-LH and HGC on the reaction film of window 2 positions.Reaction film two ends overlap joint filter membrane, filter membrane works the effect of propagating sample at this.At the bottom of this external box take back in the middle part, and the position inwall is provided with a horizontal platform (10) evenly slowly to be propagated to window 2,3 and 4 so that guarantee sample.

Working as by above structure then can be in order to test with lid and box base pressure fashionable (filter membrane one reaction film bonding jumper is pressed in therebetween), can splash into sample or directly dip in from window 1 during survey and get with medicine box one termination, treat then to show the negative control thick stick in 2 minutes at window 3, window 2 shows positive thick stick, and window 4 shows the reaction termination.

Filter membrane material can be selected the strong commodity filter paper of water absorptivity for use, and reaction film can be selected chemical bonding commodity affinity filter membrane for use.

Lid uplifting window mouth is of a size of:

Window 4: the diameter in lid inwall garden is 3 millimeters, and the diameter in lid outer wall garden is 6 millimeters

Window 3(rectangle): 4 * 5 millimeters of lid inwalls, 5 * 6 millimeters of lid outer walls

Window 2(rectangle): 4 * 8 millimeters of lid inwalls, 5 * 10 millimeters of lid outer walls

Window 1(rectangle): 4 * 30 millimeters of lid inwalls, 5 * 32 millimeters of lid outer walls

The utility model advantage:

1, compact size, easy to carry

2, easy to operate, sample can splash into also can dip in and get, and one time application of sample can be obtained a result fast

3, simple in structure, with low cost, be suitable for the commercialization manufacturing.
