Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, the present invention provides a preferred embodiment of a chemical kit.

Specifically, referring to fig. 1 and 2, a chemical kit includes an upper case 100, at least one sample part 120 for accommodating a sample to be measured, a reagent part 130 for accommodating a reaction reagent, and a reaction part 140 for mixing the sample to be measured and the reaction reagent, which are provided on the upper case 100. The sample part is used for accommodating a sample to be detected, the reagent part is used for accommodating a reaction reagent which is chemically reacted with the sample to be detected, and the reaction part is used for mixing the sample to be detected and the reaction reagent to ensure that the sample to be detected and the reaction reagent are chemically reacted.

The sample to be tested can be placed in the reaction part 140, the reaction reagent is placed in the reaction part 140, and the sample to be tested and the reaction reagent are subjected to chemical reaction, so that the mixed liquid can be subjected to chemical analysis, and a corresponding analysis result can be obtained.

Referring to FIGS. 1 and 2, the chemical kit further includes at least one unused tip 151 provided on the upper case 100, a tip placing part 152 for fixing the unused tip 151, and a tip removing part for removing the used tip 151.

The attraction head 151 is fixed by an external attraction head fixing member, and the attraction head 151 is drawn out from the attraction head placing portion 152. Subsequently, the suction head 151 of the suction and discharge unit can sequentially suck the sample to be tested in the sample unit 120 and the reagent in the reagent unit 130, and sequentially add the sample to be tested and the reagent into the reaction unit 140, so that the sample to be tested and the reagent are uniformly mixed and then undergo a chemical reaction. After the sample to be measured and the reaction reagent are sequentially added, the tip 151 is deactivated, and the tip 151 can be detached from the tip holder by the tip detaching part.

The chemical kit is integrated with sample portion 120, reagent portion 130, reaction portion 140, suction head 151, suction head placing portion 152 and suction head detaching portion, and is high in miniaturization degree, and a plurality of independent bottles and barrels for containing samples to be measured, reaction reagents and suction heads 151 are not required to be prepared additionally, and after the suction head 151 is used up, the suction head 151 can be rapidly pulled away from a suction head fixing member, so that rapid recovery of the suction head 151 is realized.

And, because the sample part 120, the reagent part 130 and the reaction part 140 are integrally arranged, the adjacent distance is short, the liquid path for manually or mechanically and automatically sucking and adding liquid by a user is very short, the operation time is short, and the rapid chemical detection process can be completed.

Through the chemical kit, fool-type operation can be completed, and the whole chemical detection process is very simple and rapid. And the whole chemical kit can adopt cheap plastic materials, has lower cost and can be used at one time, and the chemical kit can be directly discarded after the chemical detection is finished.

Specifically, referring to FIG. 1, the tip remover comprises a penetration hole 1531 through which the used tip 151 can pass and a moving channel 1532 communicating with the penetration hole 1531, the moving channel 1532 having a width smaller than the maximum diameter of the used tip 151, and the moving channel 1532 having a width sufficient for the tip holder to pass therethrough. The penetration hole 1531 and the moving channel 1532 are provided on the upper case 100.

After the suction head 151 is used, the suction head fixture drives the suction head 151 through the penetration hole 1531 and moves along the path of the moving channel 1532. Subsequently, the tip holder moves toward the outside of the upper case 100, and the tip 151 is blocked by the lower sidewall of the moving passage 1532 due to the small diameter of the tip 151, and the tip 151 is separated from the tip holder as the tip holder continues to move outward. Therefore, the suction head 151 can be separated from the suction head fixing member quickly by the above-mentioned method without manually pulling the suction head 151 from the suction head fixing member.

Of course, the tip remover can also have other implementations:

for example, the suction head detaching part is a through hole through which the suction head 151 can pass, and the suction head fixing member drives the suction head 151 to move below the inner side wall of the through hole, the side surface of the suction head fixing member abuts against the inner side wall, and in the process that the suction head fixing member drives the suction head 151 to move up, the suction head 151 is blocked by the inner side wall of the through hole, and is separated from the suction head fixing member.

Or, the suction head detaching part includes two straight strips extending from the upper box 100 to the outside and parallel to each other, the distance between the two straight strips is smaller than the maximum diameter of the suction head 151, and the suction head fixing part enters between the two straight strips along the path from the front of the straight strips, and then the suction head 151 is driven to move upwards, and the suction head 151 is blocked by the straight strips and separated from the suction head fixing part.

Furthermore, since the tip holder is partially inserted into the notch 1521, the length of the moving path 1532 can be further shortened, which contributes to the overall miniaturization of the upper case 100.

Still further, referring to fig. 5, a plurality of strip-shaped bosses 1522 are disposed on the inner side wall of the suction head placing portion 152, and when an unused suction head 151 is embedded into the suction head placing portion 152, the strip-shaped bosses 1522 can clamp the suction head 151, so as to ensure that the suction head 151 can be fixed in the suction head placing portion 152 without external force.

Also, after the tip 151 is used, the tip 151 is detached by the tip detaching part, and the tip 151 drops into the waste receiving cavity 300. Thus, the chemical cartridge is integrated with the waste-holding cavity 300, and the waste liquid and the used pipette tip 151 can be rapidly collected without additionally preparing a device for discarding the waste liquid and the pipette tip 151, thereby preventing environmental pollution.

Further, referring to fig. 6, the lower case 200 is provided with a first through hole 250 through which the reaction part 140 can be observed, and the reaction part 140 can be visually observed through the first through hole 250.
