Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1

As shown in FIG. 1, the fluid test card with short reagent strips comprises a test card body 1, a test card sleeve 2 and a test reagent strip 3.

The detection card body 1 comprises a holding box body 1-1, a cover plate, a limiting rib 1-2, a reinforcing rib 1-3 and a blocking rib 1-4. The main body of the holding box body 1-1 is rectangular. The holding box body 1-1 is internally provided with a U-shaped limiting rib 1-2. The limiting ribs 1-2 surround a strip-shaped reagent strip placing groove. The width of reagent strip standing groove is 2 ~ 5 cm. The bottom end of the reagent strip placing groove is communicated with the bottom end face of the holding box body 1-1. A plurality of reinforcing ribs 1-3 are arranged between the limiting ribs 1-2 and the inner side wall of the holding box body 1-1. The reinforcing ribs 1-3 are used for increasing the strength of the detection card body 1, so that the detection card body 1 can adopt a smaller wall thickness, and materials are saved. The blocking ribs 1-4 are arranged on the middle upper portion of the reagent strip placing groove enclosed by the limiting ribs 1-2.

The detection reagent strip 3 is arranged in the reagent strip placing groove. The edges of two sides of the detection reagent strip 3 are respectively contacted with two side walls of the reagent strip placing groove. The inner end edge of the detection reagent strip 3 is contacted with the blocking ribs 1-4, and the outer end edge extends out of the holding box body 1-1 from the opening of the reagent strip placing groove. The detection reagent strip 3 comprises a PS bottom plate (PS is polystyrene), absorbent filter paper, a polyester fiber membrane, a glass fiber membrane and a nitrocellulose membrane which are sequentially overlapped and fixed from bottom to top. The detection reagent strip 3 is coated with detection raw materials. Taking the methcathinone test card as an example, the test reagent strip is coated with a methcathinone antigen and a coupling microsphere antibody (the selection of the test raw materials belongs to the prior art). The outer end of the reagent strip is a detection end.

Because the stop ribs 1-4 play a limiting role in the detection reagent strip 3, even if the length of the detection reagent strip 3 is smaller than that of the holding box body 1-1, the outer end of the detection reagent strip 3 still can extend out of the holding box body 1-1. Therefore, the utility model discloses well design keep off muscle 1-4 and make the utility model discloses under the prerequisite that need not shorten test card body 1, shortened the length of detection reagent strip 3 to greatly reduced the manufacturing cost of fluid detection card.

The cover plate is fixed on the open side of the holding box body 1-1. The position on the cover plate corresponding to the detection reagent strip 3 is provided with an observation notch, or the cover plate is made of transparent material without the observation notch, so that a user can observe the color reaction of the detection reagent strip 3. The bottom of the detection card body 1 is provided with a card sleeve connecting part with the width smaller than the width of the main body. The shape of the opening of the inner cavity of the detection card sleeve 2 corresponds to the shape of the connecting part of the detection card body 1. Detect cutting ferrule 2 cover in the transportation on the cutting ferrule connecting portion of detecting card body 1 for the outer end of protection detection reagent strip 3.

The working principle of the utility model is as follows:

when the fluid detection card is activated, the detection card sleeve 2 is removed and the outer end of the reagent strip is inserted completely into the fluid sample to be detected. When the time length of the reagent strip inserted into the fluid sample reaches a preset value, the fluid sample flows upwards along the reagent strip, and a strip result is displayed. The person of examining can take out detection card body 1, will detect the card cover simultaneously and again cover the bottom that detects card body 1.

Because the detection card is mostly supporting instrument equipment use in the trade field, conventional detection card outward appearance is comparatively fixed, can bring adverse effect to the testing process if shorten the length of detecting the card. The utility model discloses a reduce and detect the card cost, under the prerequisite that does not change the detection card outward appearance, set up in its inside and keep off muscle 1-4, the fender muscle structure of setting up can effectively reduce the use of reagent strip material, because the cost major part of detection card is concentrated on the reagent strip, reduces the reagent strip material and uses and can effectively reduce the detection card cost.

Example 2

A fluid detection card of a short reagent strip comprises a detection card body 1, a detection card sleeve 2 and a detection reagent strip 3. The detection card body 1 in this embodiment has the sliding groove 4 or the sliding rail provided at the edge of both sides on the basis of embodiment 1. The connection relationship between the test card body 1 and the test reagent strip 3 in this embodiment is the same as that in embodiment 1.

The part of the detection reagent strip 3 extending out of the detection card body 1 is provided with a temperature detection module. The temperature detection module is four pieces of temperature color development test paper 5 which are arranged in sequence at intervals. The four pieces of temperature color test paper 5 have different color development temperatures. The developing temperature range is 32 ℃ to 38 ℃ (the developing temperature of the four pieces of temperature developing test paper 5 in the embodiment is 32 ℃, 34 ℃, 36 ℃ and 38 ℃).

The detection card sleeve 2 is sleeved at the bottom end of the detection card body 1. Two sliding bulges are arranged in the inner cavity of the detection card sleeve 2. Two sliding bulges in the detection card sleeve 2 and the sliding groove 4 or the sliding rail on the detection card body 1 form a sliding pair. The outer end of the detection card sleeve 2 is provided with a yielding through groove 2-1 at a position corresponding to the detection reagent strip 3.

When detecting cutting ferrule 2 and sliding to outer extreme position (non-user state), the part that detects reagent strip 3 and stretch out detection card body 1 is wrapped up by detection cutting ferrule 2 completely, and at this moment, detect cutting ferrule 2 and play the effect of protection reagent strip. When sliding to the inner limit position (use state), the four temperature detection modules on the detection reagent strip 3 all extend out of the yielding through groove 2-1 of the detection card sleeve 2, and at the moment, the detection reagent strip 3 can be used for detection. When detecting cutting ferrule 2 and being in outer extreme position and interior extreme position, all fix a position through the trip point and the draw-in groove cooperation.

The working principle of the utility model is as follows:

when the detection card is started, the detection card sleeve slides to the inner limit position in the direction of the detection card body 1, so that the outer end of the reagent strip 4 extends out of the detection card sleeve and can completely extend out of the yielding through groove 2-1 through the detection card sleeve reserved passage 6 in the sliding process of the detection card sleeve towards the detection card body.

And extending the outer end of the reagent strip into the fluid sample to be detected, so that the four temperature detection modules are all immersed in the fluid sample. The four temperature detection modules automatically develop color according to the temperature of the fluid specimen. The detector judges the temperature interval of the fluid sample according to the color development conditions of the four temperature detection modules, so as to know whether the sample leaves the human body in a short time, and provide the reference of the storage time of the sample for the detector.

When the time length of the reagent strip inserted into the fluid sample reaches a preset value, the fluid sample flows upwards along the reagent strip, and a strip result is displayed. The detector can take out the detection card body 1 and slide the detection card sleeve to the outer limit position. Because detect the cutting ferrule and detect the inseparable of card body in this embodiment, can avoid detecting the multiunit sample and detecting the cutting ferrule and leading to latent quilt tester information to obscure with the body separation.
