[0002] The saliva collection device can be used to collect saliva samples secreted from the oral cavity, and the collected saliva and saliva preservation solution are evenly mixed to ensure the integrity of the DNA in the saliva sample and its long-term preservation at room temperature.

[0003] The current saliva collection device is divided into a storage tube and a collector. When collecting saliva, the collector is put on the tube mouth of the storage tube. Due to the high viscosity of the current saliva, the saliva is easy to adhere to the inner wall of the collector and slide down. The liquid in the saliva is easy to flow out along the interface between the collector and the storage tube, which is easy to contaminate the saliva. In addition, the diameter of the connecting port on the collector is usually fixed, which is not convenient for use with storage tubes of different diameters. In addition, the current test paper needs to be manually held for saliva testing, and the process is relatively laborious. In view of the shortcomings of the existing technology, we propose a saliva sample collection device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The embodiment of the present application provides a saliva sample collection device, which solves the problem that saliva is easily discharged along the interface between the collector and the storage tube during collection, causing contamination, and the diameter of the connecting port on the collector is usually fixed, which is not convenient for adapting to storage tubes of different diameters.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model embodiment discloses a saliva sample collection device.

[0028] According to the attached Figure 1-6 As shown, a saliva sample collection device comprises:

[0029] The collection unit comprises a storage box 1 and a preservation liquid tube 2 and a collection funnel 3 arranged in the storage box 1 for collecting saliva;

[0030] It also includes a clamping unit, including a partition plate 4 arranged inside the preservation liquid tube 2 and a clamping plate 401 installed on the top of the partition plate 4 for fixing the test paper. The partition plate 4 can separate the saliva, so that two test paper tests can be performed on the current saliva at the same time;

[0031] The assembly unit includes a rope 301 that passes through the outer wall of the collecting funnel 3 for installing it and an inner bag 302 to prevent leakage. By sleeved the collecting funnel 3 on the tube mouth of the preservation liquid tube 2 and pulling the rope 301, the rope 301 will tighten the bottom of the collecting funnel 3 at the tube mouth of the preservation liquid tube 2, so that it is suitable for preservation liquid tubes 2 with different diameters. By placing the inner bag 302 in the tube mouth of the preservation liquid tube 2, saliva will flow into the preservation liquid tube 2 through the inner bag 302, avoiding the current situation that saliva is easy to flow out along the interface between the collecting funnel 3 and the preservation liquid tube 2, which is easy to cause contamination.

[0032] Both ends of the preservation liquid tube 2 are provided with threaded interfaces 203, and the outer peripheral wall of the threaded interface 203 is threadedly connected with a tube cap 204. When the preservation liquid tube 2 is not in use, the tube cap 204 can be threadedly connected to the bottom of the preservation liquid tube 2, avoiding the situation where the tube cap 204 is small and easy to lose. When in use, it can be threadedly connected to the tube mouth.

[0033] A slide groove 403 for installing the card plate 401 is provided on the top side of the dividing plate 4. Slide blocks 402 are fixedly connected to both ends of the card plate 401. The slide blocks 402 are slidably connected to the inside of the slide groove 403. By pushing the card plate 401 outward, the card plate 401 and the dividing plate 4 form a misaligned card groove. At this time, the test paper can be stuck in the card groove, and by pushing the card plate 401 inward, the card plate 401 will fix the test paper for testing, avoiding the problem that the current test paper needs to be held in hand and is easy to fall into the preservation liquid tube 2. Since the preservation liquid tube 2 is thinner and deeper, it is not convenient to take out.

[0034] A rubber ring 404 is disposed inside the slide groove 403 , and the rubber ring 404 is used to increase the friction with the slider 402 , thereby preventing the card plate 401 from moving randomly in the absence of external force.

[0035] The collecting funnel 3 is sleeved on the top side of the preservation liquid tube 2 , and the inner bag 302 is installed inside the preservation liquid tube 2 .

[0036] A cleaning rod 5 for cleaning the preservation liquid tube 2 and the collection funnel 3 is arranged inside the storage box 1 .

[0037] The outer wall of the preservation liquid tube 2 is provided with a label 202 and a scale line 201. The label 202 is convenient for recording the time of saliva, and the scale line 201 is convenient for observing the volume of saliva.

[0038] When the utility model is in use, the preservation liquid tube 2 and the collection funnel 3 are first taken out of the storage box 1, and then the collection funnel 3 is sleeved on the tube mouth of the preservation liquid tube 2, and the rope 301 is pulled, the rope 301 will tighten the bottom of the collection funnel 3 at the tube mouth of the preservation liquid tube 2, and then saliva can be spit into the collection funnel 3, and the saliva will flow into the preservation liquid tube 2 through the inner bag 302, and then the card plate 401 can be pushed outward to form a misaligned card slot with the dividing plate 4, and then the test paper can be stuck in the card slot, and the test paper will detect the saliva. After the test, the tube cap 204 at the bottom of the preservation liquid tube 2 is threadedly connected to the tube mouth, and the saliva can be preserved.

[0039] In summary, compared with the prior art, the present invention has the following beneficial effects: by arranging a rope 301 and an inner bag 302 at the bottom of the collecting funnel 3, by pulling the rope 301, the bottom of the collecting funnel 3 will be tightened at the tube mouth of the preservative liquid tube 2, so as to be suitable for preservative liquid tubes 2 with different diameters. At the same time, saliva will flow into the preservative liquid tube 2 through the inner bag 302, thereby avoiding the current situation that saliva is easy to flow out along the interface between the collecting funnel 3 and the preservative liquid tube 2, which is easy to cause contamination. By arranging a card plate 401 inside the preservative liquid tube 2, the card plate 401 can fix the test paper, thereby avoiding the current problem that the test paper is easy to fall into the preservative liquid tube 2 and is inconvenient to take out.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
