Description

Technical Field

[0001] This utility model relates to the field of reagent testing technology, and more specifically, to a test kit. Background Technology

[0002] There are many methods for testing sample reagents. The most common method is to use test strips. The test strips are placed in a test strip box or test strip card. The test strip box generally consists of two shells, with a sample dispensing port and an observation port on the upper shell. The sample dispensing port is used to add the test reagent. Currently, when adding the test reagent to the sample dispensing port, the dropper is positioned above the sample dispensing port. Even slight hand movements when adding the test reagent can easily cause the test reagent to miss the sample dispensing port and drip onto the upper shell, resulting in contamination. In addition, currently, the test reagent is added directly onto the test strip. This causes the entire amount of reagent to fall onto the test strip at once, which is too fast and can easily exceed the test strip's own capacity limit, resulting in insufficient chromatography. Therefore, this method needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a test kit to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A test kit includes an upper shell, a lower shell, and a test strip disposed within the lower shell. The upper shell has a sample dispensing port and an observation port. An extension tube is fixedly connected to the upper shell at the sample dispensing port to facilitate the insertion of a dropper into the extension tube to dispense the test reagent. A liquid guide plate is fixedly connected inside the extension tube. The liquid guide plate is inclined, and the lower inclined end of the liquid guide plate forms a falling channel with the interior of the extension tube. The falling channel is located directly above the sample dispensing port. A drip groove is provided at the upper inclined end of the liquid guide plate. Several liquid guide grooves are also provided at the top of the liquid guide plate, and the liquid guide grooves connect the drip grooves and the falling channel.

[0006] Preferably, the liquid guiding groove is provided with multiple expansion grooves.

[0007] Preferably, it also includes a sealing plug, which is inserted into the top opening of the elongated tube.

[0008] Preferably, the test strip includes a PVC base plate, a sample pad, a conjugate pad, an NC membrane, and an absorbent pad, which are sequentially bonded to the PVC base plate.

[0009] Preferably, the top of the lower shell is provided with a receiving groove, and the receiving groove is fixedly connected to both ends with limiting frames. The test strip is placed in the two limiting frames. At this time, the sample pad is located below the sample dispensing port and the NC membrane is located below the observation port.

[0010] Preferably, a baffle is fixedly connected in the middle of the receiving groove, and the two ends of the baffle are fixedly connected to the inner walls of the two sides of the receiving groove respectively. The bottom of the PVC base plate is provided with a groove that matches the baffle. When the test strip is placed in the two limiting frames, the baffle is exactly placed in the groove.

[0011] Preferably, two sliding clamps are slidably connected to the baffle. The sliding clamps are used to clamp the test strip. The top of the sliding clamp is provided with a threaded hole, and a locking bolt is threaded into the threaded hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features an extension tube at the sample inlet, which facilitates the insertion of the dropper into the extension tube to dispense the test reagent. This ensures that even slight hand movement during reagent dispensing will result in the reagent dripping into the extension tube and preventing it from falling onto the upper shell and causing contamination.

[0014] This invention features an inclined liquid guide plate inside the elongated cylinder. The operator can first drop the test reagent into the dropping trough, where it flows into the liquid guide trough and finally falls slowly into the sample application port through the drop channel, ultimately landing on the sample pad. This prevents the entire drop of reagent from falling onto the test strip at once, effectively avoiding the problem of insufficient chromatography caused by adding the sample too quickly and exceeding the test strip's own load-bearing limit.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] A test kit, please refer to Figures 1-7 It includes an upper housing 10, a lower housing 11, and a test strip 4 disposed in the lower housing 11. The upper housing 10 and the lower housing 11 are snap-fitted together or bolted together.

[0026] The upper shell 10 is provided with a sample inlet 100 and an observation port 101. An observation window 102 is fixedly connected to the observation port 101. The observation window 102 is made of transparent plastic, and the detection status of the test strip 4 can be easily observed through the observation window 102.

[0027] The test strip 4 includes a PVC base plate 40, a sample pad 401, a conjugate pad 402, an NC membrane 403, and an absorbent pad 404, which are sequentially bonded to the PVC base plate 40. These are all conventional technical features of the test strip 4.

[0028] The top of the lower housing 11 is provided with a receiving groove 110. Limiting frames 111 are fixedly connected at both ends of the receiving groove 110. The test strip 4 is placed in the two limiting frames 111. At this time, the sample pad 401 is located below the sample dispensing port 100, and the NC membrane 403 is located below the observation port 101.

[0029] A baffle 50 is fixedly connected in the middle of the receiving groove 110. The two ends of the baffle 50 are fixedly connected to the inner walls of the two sides of the receiving groove 110 respectively. The bottom of the PVC base plate 40 is provided with a groove 400 that matches the baffle 50. When the test strip 4 is placed in the two limiting frames 111, the baffle 50 is exactly placed in the groove 400.

[0030] When a test reagent falls from the sample pad 401 into the receiving groove 110, the baffle 50 can block the test reagent, preventing it from flowing into the absorption pad 404 and being absorbed by the absorption pad 404, thereby reducing the absorption capacity of the absorption pad 404 and causing inaccurate test results.

[0031] Two sliding clamps 51 are slidably connected to the baffle 50. The sliding clamps 51 are used to clamp the test strip 4. The top of the sliding clamp 51 is provided with a threaded hole, and a locking bolt 52 is threaded into the threaded hole. Tightening the locking bolt 52 so that its end abuts against the baffle 50 can fix the sliding clamp 51 on the baffle 50. After loosening the locking bolt 52, the sliding clamps 51 can be pushed to move, so that the two sliding clamps 51 clamp the two sides of the test strip 4 respectively. Then, tightening the locking bolt 52 can fix the test strip 4 and prevent the test strip from moving and affecting the detection.

[0032] An extension tube 20 is fixedly connected to the upper shell 10 at the sample inlet 100, which facilitates the insertion of the dropper into the extension tube 20 to drip the test reagent. In this way, when the test reagent is dripped, even if the hand moves slightly, the test reagent will still drip into the extension tube 20 and will not drip onto the upper shell 10 to cause contamination.

[0033] A liquid guide plate 30 is fixedly connected inside the elongation cylinder 20. The liquid guide plate 30 is inclined, and the lower inclined end of the liquid guide plate 30 forms a falling channel with the inside of the elongation cylinder 20. The falling channel is located directly above the sample inlet 100. A drip groove 300 is provided at the upper inclined end of the liquid guide plate 30. Several liquid guide grooves 302 are also provided at the top of the liquid guide plate 30. The liquid guide grooves 302 connect the drip grooves 300 and the falling channel.

[0034] The operator can first drop the test reagent into the dropping tank 300. The test reagent flows into the guide tank 302 within the dropping tank 300 and finally slowly falls into the sample application port 100 through the drop channel, and finally lands on the sample pad 401. This prevents the dropped reagent from falling onto the test strip all at once, effectively avoiding the problem of insufficient chromatography caused by adding the sample too quickly and exceeding the test strip's own load-bearing limit.

[0035] Multiple expansion grooves 303 are provided at the liquid guiding groove 302. The expansion grooves 303 can further slow down the flow rate of the test reagent.

[0036] It is worth noting that the edges at the connection between the dripping tank 300 and the guiding tank 302 are all curved edges 301, which facilitates the flow of the test reagent in the dripping tank 300 into the guiding tank 302 and prevents the test reagent from accumulating in the dripping tank 300.

[0037] It also includes a sealing plug 21, which is inserted into the top opening of the extension tube 20. Before use, the sealing plug 21 is inserted into the extension tube 20 to achieve a sealing effect and prevent air from entering the test strip.
