Specific embodiments

[0024] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-5 :

[0025] The embodiment of the present utility model discloses a colloidal gold reagent strip assembly for detecting cephalosporin drug residues, such as Figure 1 , Figure 2As shown in the figure, it includes a housing 1, a cover 2, a fixing groove 4, and a reagent strip 41. The cover 2 is fixedly installed on the housing 1. At the bottom inside the housing 1, a fixing groove 4 is integrally formed. Inside the fixing groove 4, a reagent strip 41 is provided. The reagent strip 41 has a detection end and a result end. Inside the housing 1, a partition 11 is integrally formed. On the other side of the partition 11 relative to the fixing groove 4, an airbag 3 is provided. The airbag 3 is connected to a sampling assembly for directly sucking the sample and contacting the detection end of the reagent strip 41. On the top of the cover 2, sample slots 22 corresponding one-to-one to the detection ends of the reagent strip 41 are provided. On the top of the cover 2, observation slots 21 corresponding one-to-one to the result ends of the reagent strip 41 for observing the reagent strip 41 are further provided. On the top of the cover 2, a pressing groove 23 corresponding to the airbag 3 is provided. In this embodiment, when the user performs the detection of cephalosporin drug residues, since the reagent strip 41 in the prior art directly drops the sample at the sample location, it is exposed to the external environment and is easily affected by the external environment. And there is only one test paper in the reagent strip 41 of the prior art, and the accuracy of the test paper will decrease after being stored at high temperature, high humidity or for a long time, and single detection is prone to detection errors. Using the above embodiment, the user can directly press the airbag 3 in the pressing groove 23 with a finger, use the airbag 3 to activate the sampling assembly, directly suck the sample and directly contact the detection end of the reagent strip 41, avoiding interference from the external environment, and can perform multiple simultaneous detections by setting multiple reagent strips 41 to minimize errors to the greatest extent.

[0026] As Figure 1 , Figure 2 shown; the number of the fixing grooves 4 is N, and N≥2. In this embodiment, the user can set multiple fixing grooves 4 for placing the reagent strip 41 according to the situation for performing multiple detections of cephalosporin drug residues to avoid errors.

[0027] Inside the sample slots 22 and the observation slots 21, a transparent acrylic plate (not shown in the figure) is hermetically installed. In this embodiment, by providing an acrylic plate in the sample slots 22 and the observation slots 21, while not affecting normal observation, the space between the housing 1 and the cover 2 is sealed as a closed storage space, enabling better preservation of the reagent strip 41 and avoiding excessive exposure to the external environment.

[0028] As Figure 3 shown; on the back of the cover 2, a soft film 24 is fixedly installed. The soft film 24 covers the pressing groove 23. In this embodiment, the user can apply pressure to the airbag 3 by directly pressing the soft film 24. The setting of the soft film 24 can further seal the space between the housing 1 and the cover 2 and at the same time protect the airbag 3 from being damaged due to external factors.

[0029] As Figure 4 , Figure 5As shown in the figure; the sampling assembly includes an air delivery pipe 31, a sampling box 32, a communication port 321, and a sampling head 33; the sampling head 33 is installed through the outer side wall of the housing 1; one end of the sampling head 33 arranged inside the housing 1 is connected to the sampling box 32; one end of the air delivery pipe 31 is connected and installed to the outer side wall of the sampling box 32; the other end of the air delivery pipe 31 is connected to the air hole of the airbag 3; the bottom of the sampling box 32 is provided with communication ports 321 corresponding to the number of fixing grooves 4, and the bottom of each communication port 321 is tightly pressed against the detection end of the test strip 41; in this embodiment, the user discharges the air in the air delivery pipe 31 and the sampling box 32 through the airbag 3, and uses the sampling head 33 to suck the sample. At this time, the sample will be sucked into the sampling box 32, and the communication ports 321 in the sampling box 32 will evenly distribute the sample to the detection ends of each test strip 41. After reacting for a period of time, the test result of the sample will be displayed on the result end through the test strip 41, and the user can see the test results of each test strip 41 through the observation slot 21;

[0030] As Figure 4 shown; a sealing cap 34 is connected by a thread at the opening of the sampling head 33; in this embodiment, the sealing cap 34 can better isolate the air before the detection in this embodiment to prevent air from entering the housing 1;

[0031] The sampling box 32 is made of transparent acrylic material; in this embodiment, the sampling box 32 is also made of acrylic material, which is convenient for the user to see the sampling state of the detection end of the test strip 41 through the sampling box 32;

[0032] The soft film 24 is made of rubber material.

[0033] The implementation principle of the embodiment of the present utility model is as follows:

[0034] When the present utility model is in use, the user needs to remove the sealing cap 34, and press the airbag 3 by pressing the soft film 24 of the pressing groove 23 to discharge the air in the air delivery pipe 31 and the sampling box 32, and use the sampling head 33 to suck the sample. At this time, the sample will be sucked into the sampling box 32, and the communication ports 321 in the sampling box 32 will evenly distribute the sample to the detection ends of each test strip 41.
