Description

Technical Field

[0001] The utility model relates to the technical field of saliva collectors, in particular to a disposable saliva collector. Background Art

[0002] Saliva contains a range of biomarkers, including DNA, RNA, proteins, and metabolites, making it an ideal sample for detecting a range of diseases, including respiratory infections, sexually transmitted diseases, tropical diseases, hormonal disorders, and cancer. However, since saliva is kept away from human body temperature, the human cells in it are susceptible to death. Furthermore, during collection, saliva DNA comes into contact with air, where bacteria or viruses in the air can easily multiply in saliva with high moisture content, contaminating the saliva DNA sample. Therefore, in actual use, a stabilizing solution must be added promptly after saliva is collected to ensure that the saliva can be stored at room temperature and to inhibit the growth of bacteria or viruses in the saliva.

[0003] Currently, there are many saliva collectors on the market, such as patents "CN110960265A, Saliva Collector" and "CN219782606U, Saliva Collector". These traditional saliva collectors all have a problem: the user needs to add the stabilizing liquid to the collection tube after collecting the saliva. This addition process is difficult for one person to operate and can easily contaminate the saliva or cause saliva to flow in. In addition, after the collection is completed, the tester needs to sample the saliva and stabilizing liquid in the collection tube, which makes the quantitative operation complicated and inconvenient. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a disposable saliva collector with rich functions and accurate detection.

[0005] In order to achieve the above-mentioned objectives, the present invention provides a disposable saliva collector, comprising a collection funnel, a collection bottle and a dripping stopper. A sealed bottle is fixedly embedded in the bottle cavity of the collection bottle, and the collection bottle cavity serves as a saliva collection cavity in the area above the top surface of the sealed bottle; the collection funnel and the dripping stopper are both replaceably installed at the bottle mouth of the collection bottle; the dripping stopper is provided with a dripping channel extending from its top to the bottom and communicating with the saliva collection cavity; the bottom of the dripping stopper is provided with a puncture rod that can be inserted into the bottle cavity of the collection bottle, wherein the lower end of the puncture rod is formed with a puncture tip that can puncture the top surface of the sealed bottle.

[0006] Furthermore, it also includes a plug cover threadedly sleeved on the dripping plug, and the inner top surface of the plug cover is formed with a sealing column that can be sealably inserted into the dripping port of the dripping channel.

[0007] Furthermore, the inner circumferential surface of the dripping plug is formed with a first inner thread which is threadably matched with a first outer thread preformed on the outer circumferential surface of the bottle mouth of the collecting bottle.

[0008] Furthermore, the bottom of the collecting funnel is integrally formed with a guide portion that can be embedded and inserted into the collection bottle cavity, wherein the outer peripheral surface of the guide portion is integrally formed with a plurality of supporting blocks that can conflict with the inner wall of the collection bottle cavity.

[0009] Furthermore, the outer peripheral surface of the guide portion is integrally formed with a plurality of limiting blocks that can come into contact with the bottle mouth of the collecting bottle.

[0010] Furthermore, the upper end of the puncture rod is formed with a plurality of fixed blocks arranged in a ring shape and engaged with the bottom of the drip channel, and a liquid passage communicating with the saliva collection chamber and the drip channel is formed between any two adjacent fixed blocks.

[0011] The present invention adopts the above-mentioned solution, and its beneficial effects are as follows: by arranging a sealed bottle inside the collection bottle to store the stabilizing liquid, and arranging a puncture rod at the bottom of the dripping plug, when the dripping plug is screwed into the collection bottle, the puncture rod can pierce the top surface of the sealed bottle, allowing the stabilizing liquid to flow into the saliva collection chamber, thereby achieving mixing of saliva and the stabilizing liquid, ensuring that the saliva sample can be stored at room temperature and inhibiting the reproduction of bacteria or viruses in the saliva; at the same time, during the process of collecting saliva, the stabilizing liquid is sealed in the sealed bottle and will not come into contact with the saliva, thereby ensuring the purity of the saliva; in addition, because the dripping plug is connected to the collection bottle by a threaded connection, it is easy to disassemble, which is convenient for subsequent sampling operations; therefore, the present invention has the advantages of compact structure, easy use, and integrated saliva collection and mixing.

[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention is provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0026] See attached Figure 1-12 As shown, in this embodiment, a disposable saliva collector includes a collection funnel 1, a collecting bottle 2, a dripping stopper 3 and a stopper cover 5, wherein a sealing bottle 4 is fixedly embedded in the bottle cavity of the collecting bottle 2. Specifically, the sealing bottle 4 can contain a stabilizing liquid (the stabilizing liquid can be used to react with the saliva sample and is commonly used in saliva testing. It is a conventional technology and will not be described in detail here), and after the sealing bottle 4 is filled with the stabilizing liquid, it can be sealed with a film at the bottle mouth to achieve a sealing effect; in addition, the outer edge of the bottle mouth of the sealing bottle 4 is formed with a ring-shaped portion that can be interference-engaged with the inner wall of the bottle cavity of the collecting bottle 2. In order to improve the clamping stability of the sealing bottle 4, the inner wall of the bottle cavity of the collecting bottle 2 of this embodiment is formed with an annular groove for interference-engaging the annular portion. Therefore, after sealing with the film, the sealing bottle 4 is placed as a whole in the bottle cavity of the collecting bottle 2 until the annular portion moves to the annular groove for interference-engaging, and the bottle cavity of the collecting bottle 2 is used as a saliva collection chamber 21 in the area above the top surface of the sealing bottle 4.

[0027] In this embodiment, the collecting funnel 1 and the dripping stopper 3 are both replaceably installed at the bottle mouth of the collecting bottle 2. During actual use, the collecting funnel 1 is first installed at the bottle mouth of the collecting bottle 2, and the user then spits saliva toward the collecting funnel 1 so that the saliva flows into the saliva collecting chamber 21 of the collecting bottle 2 through the collecting funnel 1. Then, the collecting funnel 1 is removed, and the dripping stopper 3 is installed at the bottle mouth of the collecting bottle 2 to facilitate subsequent transportation and dripping operations.

[0028] In this embodiment, the bottom of the collecting funnel 1 is integrally formed with a guide portion 11 that can be embedded and inserted into the bottle cavity of the collecting bottle 2, wherein the outer peripheral surface of the guide portion 11 is integrally formed with a plurality of support blocks 12 that can interfere with the inner wall of the bottle cavity of the collecting bottle 2. By utilizing the plurality of support blocks 12 to interfere with the inner wall of the bottle cavity of the collecting bottle 2, the collecting funnel 1 will not loosen or fall off after being installed on the collecting bottle 2, and will be more stable and more convenient for users to use.

[0029] Furthermore, the outer peripheral surface of the guide part 11 is integrally formed with a plurality of limit blocks that can limit and interfere with the bottle mouth of the collecting bottle 2. The limit blocks are used to limit the depth of the guide part 11 inserted into the collecting bottle 2 to prevent excessive insertion.

[0030] In this embodiment, the inner circumference of the dripping stopper 3 is formed with a first internal thread that threadably engages with a first external thread preformed on the outer circumference of the mouth of the collection bottle 2. The threaded connection between the first external and first internal threads enables quick installation of the dripping stopper 3 and the collection bottle 2. Furthermore, the dripping stopper 3 is provided with a dripping channel 31 extending from its top to its bottom and communicating with the saliva collection chamber 21. The dripping channel 31 allows saliva and mixed liquid to drip out during subsequent testing.

[0031] In this embodiment, the bottom of the drip stopper 3 is provided with a puncture rod 32 that can be inserted into the bottle cavity of the collection bottle 2. The lower end of the puncture rod 32 is formed with a puncture tip 33 that can pierce the top surface of the sealed bottle 4. Specifically, during the installation of the drip stopper 3 into the collection bottle 2, the puncture tip 33 gradually approaches the sealed bottle 4 until the puncture tip 33 pierces the sealing film at the mouth of the sealed bottle 4, thereby connecting the bottle cavity of the sealed bottle 4 with the saliva collection chamber 21. When the collection bottle 2 is in an upright position, saliva can flow into the bottle cavity of the sealed bottle 4, or when the collection bottle 2 is in an inverted position, the stabilizing liquid can flow into the saliva collection chamber 21, thereby achieving the effect of mixing saliva and the stabilizing liquid. This method is mainly used to prevent the stabilizing liquid from flowing out or leaking during transportation or use, ensuring transportation convenience and detection accuracy.

[0032] In this embodiment, the upper end of the puncture rod 32 is formed with a plurality of fixed blocks arranged in a ring and engaging with the bottom of the drip channel 31. This means that the fixed blocks and the drip channel 31 employ an interference fit, which facilitates production and assembly, and provides greater stability and reliability. Furthermore, a liquid passageway is formed between any two adjacent fixed blocks, connecting the saliva collection chamber 21 and the drip channel 31. This allows saliva and its mixture to flow through the liquid passageway into the drip channel 31, ultimately dripping out of the outlet of the drip channel 31.

[0033] In this embodiment, the plug cover 5 is threadedly mounted on the dripping plug 3. The inner circumferential surface of the plug cover 5 is formed with a first internal thread that is threadably engaged with a second external thread formed on the outer circumferential surface of the dripping plug 3. The threaded engagement between the first internal thread and the second external thread enables the plug cover 5 to be mounted on the dripping plug 3. The inner top surface of the plug cover 5 is formed with a sealing post 34 that can be sealably inserted into the dripping port. That is, when the plug cover 5 is mounted on the dripping plug 3, the sealing post 34 is correspondingly and sealably inserted into the dripping port of the dripping channel 31, thereby preventing the risk of saliva and its mixture from leaking and contaminating through the dripping port during transportation.

[0034] In summary, the saliva collector provided in this embodiment, through the adoption of a unique structural design, realizes the convenient operation of saliva collection, mixing and dripping, improves the collection efficiency and accuracy of saliva samples, and at the same time ensures the hygiene and safety during transportation and storage, and has high practical value.
