DETAILED DESCRIPTION

[0027] The content of the utility model will be further explained in detail in combination with specific embodiments:

[0028] As Figures 1-2 shown, a kind of detection reaction consumables, including detection part 1, storage part 2, sealing cover 3 and plug-in part 4, first containing cavity 11 is equipped in detection part 1, second containing cavity 21 is equipped in storage part 2, first containing cavity 11 and second containing cavity 21 are communicated by the through hole 22 being arranged in the side wall of storage part 2, and first containing cavity 11 and second containing cavity 21 are respectively equipped with reagent to be reacted and drying agent, keep the dryness of reagent by drying agent all the time, because second containing cavity 21 has larger containing space, the content of drying agent stored therein is more, can adapt to humidity environment of different regions, keep the dryness of reagent, wherein, one end of storage part 2 is equipped with sealing cover 3, prevent the moisture in external environment from entering storage part 2 through through hole 22 or other crevice, to thereby destroy dry environment, and plug-in part 4 is equipped in the end of detection part 1 away from storage part 2, and along the axial direction of plug-in part 4 is equipped with liquid outlet hole 41 being communicated with first containing cavity 11, after containing tissue cell solution is dropped into first containing cavity 11, storage part 2 is inserted tightly in detection part 1, and plug-in part 4 is inserted in detection box, when solution and reagent react, flow into detection box along liquid outlet hole 41, result is obtained by detection box.

[0029] In the embodiment, the first accommodating cavity 11 comprises a reaction cavity 111 and a communicating cavity 112. The reaction cavity 111 provides a reaction space for the reagent. The communicating cavity 112 is in communication with the second accommodating cavity 21 through the through hole 22, so that the desiccant can fully absorb the moisture in the first accommodating cavity 11 and the second accommodating cavity 21, preventing the reagent from being hygroscopic or deliquescent, which leads to the failure or poor effect of the reagent. During the reaction of the reagent, the reaction cavity 111 needs to be isolated from the second accommodating cavity 21 to reduce the contact between the reagent and the external environment (such as humidity) during the reaction, thereby improving the stability of the reagent and preventing the failure of the reagent due to hygroscopicity or deliquescence. Therefore, the connecting position of the reaction cavity 111 and the communicating cavity 112 is provided with a first circular arc surface 113, and the end of the storage part 2 close to the detection part 1 forms a second circular arc surface 23. When the reagent reacts, the first circular arc surface 113 and the second circular arc surface 23 are in close contact, thereby isolating the reaction cavity 111 and the second accommodating cavity 21.

[0030] Further, as shown in Figures 2-3 In order to ensure that the reagent is in a dry state before use and is isolated during use, a ring-shaped detachable pull ring 12 is arranged at the end of the detection part 1 away from the plug-in part 4, and the ring-shaped pull ring 12 is concentric with the detection part 1 and has the same diameter to prevent the plug-in of the storage part 2. When not in use, the pull ring 12 is on the detection part 1. When the storage part 2 is plugged in, the end of the storage part 2 away from the sealing cover 3 is located in the communicating cavity 112, and the second accommodating cavity 21 always maintains communication with the communicating cavity 112, so that the reagent is always in a dry state. When in use, the pull ring 12 is removed, and the storage part 2 is pressed axially along the detection part 1, and the end of the storage part 2 away from the sealing cover 3 is located in the reaction cavity 111, so that the reagent is isolated.

[0031] Specifically, one end of the pull ring 12 extends to the outside of the detection part 1 to form a hand holding part 13. The pull ring 12 can be detached through the hand holding part 13, so that the user can more easily grasp the pull ring 12 and then apply force to open it.

[0032] A flow guide column 42 is arranged between the two liquid outlet holes 41, and the flow guide column 42 is arranged along the axial direction of the detection part 1 and extends away from the detection part 1. The solution flowing out of the liquid outlet hole 41 is guided to flow in a specific direction, introduced into the detection box, and the speed of the solution entering the detection box can be accelerated, thereby shortening the detection time.

[0033] As shown in Figures 4-5As shown, in order to ensure that the storage part 2 and the detection part 1 are not separated from each other during the transportation and storage and detection processes, and always keep the reagent dry, the pull ring 12 and the inner wall of the detection part 1 are provided with grooves 5, and the outer wall of the storage part 2 is provided with protrusions 6 matched with the grooves 5, which effectively prevent the accidental separation of the storage part 2 and the detection part 1 during the transportation or storage process, and even under the condition of jolting or vibration, the design can ensure the close connection of the two, prevent the reagent from leaking or being damp, and at the same time, because the gap between the detection part 1 and the storage part 2 is minimized, the overall sealing performance can be enhanced, further preventing the influence of moisture on the reagent.

[0034] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application, therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
