Abstract
The utility model relates to an automatic filling test card for a bacteria drug sensitivity test, which comprises a plastic plate and test holes on the plastic plate. The test holes are a series of through holes. Transparent air-permeable water-repellent films which cover the two surfaces of the plastic plate and the series of through holes form transparent chambers. A liquid inlet pipe is sequentially communicated with a liquid inlet groove, capillary grooves and the test holes on the surface of the plastic plate through side surface interfaces. A pipe cap is arranged at the mouth of the liquid inlet pipe. The liquid inlet pipe is hermetically inlaid in the pipe cap and is integrally connected with the pipe cap. A groove is arranged on the surface of the pipe cap. A water-soluble plastic film is arranged in the groove. A protection pad is arranged on the external side of the water-soluble plastic film. A center hole is arranged on the protection pad. A dam-proof film is arranged on the external side of the protection pad. When the automatic filling test card is used, after the water-soluble plastic film at the mouth of the liquid inlet pipe is automatically dissolved, bacteria liquid enters the test holes under the effect of atmospheric pressure, automatic filling is completed, true minimal inhibitory concentration (MIC) can be obtained, the drug sensitivity test can be completed, the structure is simple, the automatic filling test card is convenient to use, the cost is low, and the needs of clinical researches can be met.
Description
Technical field
The utility model relates to a kind of drug sensitive test equipment, particularly relates to a kind of bacterial susceptibility test and fills test card automatically.
Background technology
The patient needs the doctor to use antibiotic therapy after by infectation of bacteria.The doctor to patient's sample cultivate obtain pathogenic bacteria after, need carry out drug sensitivity test, observe which kind of microbiotic and can suppress pathogenic bacteria growth, select suitable microbiotic to treat targetedly then.Existing medicament sensitivity testing method has following several: (1) pastes paper disk method: survey inhibition zone diameter, judge whether sensitivity according to the size of antibacterial ring.This method advantage is that method is simple; Shortcoming is to judge minimal inhibitory concentration, operates consuming time longer.(2) agar dilution: microbiotic is added in the agar, and different agar plates is made into different pharmaceutical concentration, is coated with bacterium liquid then on agar, sees which concentration growth bacterium.Advantage is accurate; Shortcoming is loaded down with trivial details, length consuming time, and consumptive material is many.(3) liquid broth dilution method: different meat soup pipes is added an amount of microbiotic, be made into different drug levels, insert detected bacterial classification then, observing which pipe bacterium has growth.The same agar dilution of relative merits.(4) E-test method adopts external import test strip.Though detected result result near MIC, is not real MIC, it is higher to detect cost.
Here MIC is meant minimal inhibitory concentration, i.e. the needed minimum antibiotic concentration of bacteria growing inhibiting.Existing full-automatic susceptibility instrument or semi-automatic susceptibility instrument, adopt broth dilution method mostly, the inoculation susceptibility hole of selecting is generally 3-4, be responsive break, resistance break and three holes of intermediary's break, can only judge resistance or sensitivity simply like this, can not obtain real MIC, can not satisfy the needs of clinical study, also need the instrument of special expensive to test.

Described capillary channel middle part is provided with the U-shaped bend.
Described test hole number is 13 ~ 16, and test hole is vertically arranged along plastic plate.
Described test hole is per 16 and is arranged in a row that test hole is a two or more rows.
Described air-permeable, hydrophobic film surface is provided with protective membrane, and test hole is oval, circular or square.
Positive beneficial effect of the present utility model:
(1) automatic filling test card of the present utility model, be provided with a plurality of drug levels in the series of tests hole, after the water-soluble plastic film of the mouth of pipe dissolves during use, bacterium liquid enters each test hole under the normal atmosphere effect, finish automatic filling, can access real minimal inhibitory concentration MIC, thereby finish drug sensitive test.
(2) the utility model is reasonable in design, simple in structure, and is easy to use, and cost is lower, do not need complex instrument in the test, can satisfy the needs of clinical study, easy to utilize.
Description of drawings

Fig. 2: test card A-A of the present utility model is to sectional view.
Fig. 3: the structural representation of pipe cap in the utility model.
Fig. 4: two of test card structural representation of the present utility model.
Among the figure, 1 is test hole, and 2 is plastic plate, and 3 is capillary channel, and 4 is liquid-inlet pipe, and 5 is pipe cap, and 6 is lead channel, and 7 is transparent air-permeable, hydrophobic film, and 8 is protective membrane, and 9 is the water-soluble plastic film, and 10 is centre hole, and 11 is neonychium, and 12 is damp-proof membranes.
Embodiment
Embodiment 1: referring to Fig. 1, Fig. 2, Fig. 3, test card is filled in a kind of bacterial susceptibility test automatically, comprises plastic plate and the test hole that is positioned on the plastic plate, and test hole is 16 oval-shaped through holes, vertically is arranged as a row along plastic plate.The transparent air-permeable, hydrophobic film and the serial ellipse hole of plastic plate two surface coverage form transparent chamber.
The external liquid-inlet pipe of test card; liquid-inlet pipe is communicated with lead channel, capillary channel and the test hole of plastic sheet surface successively by test card side interface; the capillary channel middle part is provided with the U-shaped bend; the liquid-inlet pipe mouth of pipe is provided with pipe cap; liquid-inlet pipe closed set and become one in pipe cap with pipe cap; the pipe cap surface is provided with groove; be provided with the water-soluble plastic film in the groove; the water-soluble plastic film outside is provided with neonychium; neonychium is provided with centre hole; centre hole, liquid-inlet pipe are positioned on the same medullary ray, and the neonychium outside is provided with damp-proof membranes.
