Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention: A saliva sample detection device, including a detection box 1, a collection rod 6 and a detection test strip 11. A fixing groove 2 is provided in the middle of the interior of the detection box 1, and a collection rod 6 is inserted in the middle of the inner wall of the fixing groove 2. A detection test strip 11 is provided on the lower side of the interior of the detection box 1, and a slider 4 is provided in the middle of the interior of the detection box 1. The outer wall surface of the slider 4 is connected to the outer wall end of the collection rod 6. An observation groove 12 is provided at the lower end of the outer wall of the detection box 1. In this structure, a cotton block is connected to the end of the collection rod 6, and the detection test strip 11 is a mature existing technology and will not be elaborated here. The mutual connection between the slider 4 and the collection rod 6 can control the manufacturing cost, so that the collection rod 6 can be manufactured or purchased separately;
[0023] Furthermore, a sliding groove 3 is formed in the middle inside the detection box 1, and the outer wall surface of the slider 4 is fitted to the middle of the inner wall of the sliding groove 3. A clamping groove 5 is formed in the outer wall surface of the slider 4, and the inner wall of the clamping groove 5 is adapted to the outer end of the collection rod 6. A plurality of anti-slip lines are arranged at the upper end of the outer wall of the slider 4. This structure can stably bond the collection rod 6 to the inner wall of the clamping groove 5 with glue during production. At the same time, during use, it increases the friction force on the outer wall of the slider 4, making it better to control and use.
[0024] Furthermore, a limiting block 7 is arranged at the left end of the outer wall of the slider 4, and limiting grooves 8 are formed on both the front and rear sides of the inner wall of the sliding groove 3. The outer wall surface of the limiting block 7 is adapted to the inner wall surface of the limiting groove 8. After the slider 4 is pushed to a certain position, the limiting block 7 will fit with the limiting groove 8, so that the collection rod 6 can be used in a stable state without manual long-term pressing control.
[0025] Furthermore, an extrusion groove 9 is formed at the rear end of the inner wall of the fixing groove 2, and a guide groove 10 is formed at the lower end of the inner wall of the extrusion groove 9. The inner wall of the guide groove 10 communicates with the outer wall surface of the test strip 11. The inner wall surface of the extrusion groove 9 is conical, and the inner wall of the extrusion groove 9 is adapted to the outer end of the collection rod 6. After the collection rod 6 finishes sampling, this structure can move the collection rod 6 to the position of the inner wall of the extrusion groove 9. The inner wall of the extrusion groove 9 contracts from front to back. When the collection rod 6 continues to move backward, the saliva collected by the cotton block at the end of the collection rod 6 is extruded through the tightening of the inner wall of the extrusion groove 9 and flows through the guide groove 10 to the position of the test strip 11 for absorption and detection by the test strip 11.
[0026] Furthermore, a glue cover 13 is connected to the front end of the outer wall of the detection box 1, and a sealing ring is arranged on the outer wall surface of the glue cover 13. The rear end of the outer wall of the glue cover 13 is fitted to the inner wall of the fixing groove 2. A convex strip is fixedly connected to the left end of the outer wall of the glue cover 13. During use, this structure can seal and close the fixing groove 2 through the glue cover 13. After the outer wall packaging bag of the detection box 1 is taken out, it can prevent external air from contaminating the collection rod 6. At the same time, after collection is completed, it is still closed through the glue cover 13 to reduce the volatilization time and spread of saliva in the air.
[0027] Furthermore, a blocking strip is fixedly connected to the middle of the inner wall of the observation groove 12, and a transparent plastic sheet is arranged on the upper side of the inner wall of the observation groove 12. The plastic sheet is adapted to the rear end of the outer wall of the test strip 11. This structure can observe the changes after the test strip 11 absorbs through the observation groove 12.
[0028] Working principle: When in use, the detection box 1 can be taken out of the packaging bag. At this time, the closed state of the glue cover 13 can prevent the collection rod 6 in the fixing groove 2 from directly contacting the air, which may cause partial contamination. Then, when it is needed, the glue cover 13 can be opened, the slider 4 can be pushed to drive the collection rod 6 to move horizontally. When the slider 4 moves to the front side of the inner wall of the chute 3, the limiting block 7 will be fitted with the front limiting groove 8. At this time, the collection rod 6 moved out of the fixing groove 2 can be used to collect saliva. After the collection is completed, the slider 4 can be pushed to fit with the rear limiting groove 8. When the slider 4 moves, it will drive the collection rod 6 to move. When the collection rod 6 moves inside the fixing groove 2, it will be squeezed against the inner wall of the extrusion groove 9, so as to squeeze out the saliva collected by the cotton block at the end of the collection rod 6, so that the saliva flows out and is guided by the guide groove 10 to flow to the outer wall surface of the test strip 11 and is absorbed by the test strip 11. When the collection rod 6 is retracted and moved into the fixing groove 2, the glue cover 13 can be manually rotated and pressed to close the opening of the fixing groove 2, reducing the volatilization and spread of saliva. Then, the detection box 1 can be placed and waited for a period of time, and then the observation slot 12 can be observed to observe the change of the test strip 11, so as to display the test result. The above is the whole working principle of the present utility model.
[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model 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 utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
