[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to the following: Figures 1 to 3 The present invention provides a portable oral saliva collector. The portable oral saliva collector includes: a collection tube 1, an inlet nozzle 4, a sealing disc 2, a vent valve, and a support 5. The bottom of the collection tube 1 is sealed, while the top is open. The inlet nozzle 4 is located on one side of the top of the collection tube 1 and communicates with it. The sealing disc 2 is slidably disposed within the collection tube 1, adapting to the inner wall of the collection tube 1 and collecting saliva from the inner wall of the collection tube 1 through sliding. The vent valve is mounted on the sealing disc 2. The support 5 is pivotally disposed on the collection tube 1 for engaging a timing device.

[0022] The advantages of this portable oral saliva collector are as follows: Compared with the prior art, the bottom of the collection tube 1 is sealed while the top is open in this portable oral saliva collector. The inlet 4 is located on one side of the top of the collection tube 1 and communicates with the collection tube 1. The sealing disc 2 is slidably disposed inside the collection tube 1, and a vent valve is installed on the sealing disc 2. The bracket 5 is oscillatingly disposed on the collection tube 1.

[0023] In practical application, the patient allows saliva to flow into the collection tube 1 through the inlet 4. The vent valve ensures smooth saliva flow. After the timing device completes the timing, the sealing disc 2 slides within the collection tube 1 to collect the saliva on its inner wall. This application has a relatively simple structure, can accurately read the amount of saliva in the patient's mouth over a period of time, ensures accurate results, is convenient to use, and has strong practicality.

[0024] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 1 and Figure 2 The inlet nozzle 4 is detachably inserted into the collection tube 1. This design allows the inlet nozzle 4 to be removed after saliva collection is complete, enabling the collection tube 1 to be inserted into the centrifuge for further testing. If the inlet nozzle 4 is not removed, it will cause positional interference with the centrifuge.

[0025] When the sealing disc 2 slides inside the collection tube 1, it precisely conforms to the inner wall of the collection tube 1, thus facilitating better saliva collection. Its fit with the inner wall of the collection tube 1 is excellent, preventing gaps from forming due to sliding and thus avoiding saliva loss. An air vent valve is installed on the sealing disc 2; its function is to maintain air pressure balance within the collection tube 1. When collecting saliva, air needs to be expelled from the tube; the air vent valve allows air to enter smoothly, preventing positive pressure from forming inside the tube and affecting saliva collection, while also preventing outside air from entering and contaminating the saliva.

[0026] The swing-mounted bracket 5 is designed to engage the timing device on the collection tube 1, facilitating the timing of the saliva collection process. Users can accurately record the saliva collection time using the timing device engaged on the bracket 5, enabling more scientific analysis and research of the saliva sample later. The swing-mounted flexibility of the bracket 5 during saliva collection makes the installation and operation of the timing device very convenient and does not interfere with the normal progress of saliva collection.

[0027] After saliva collection is complete, the timing device can be removed from the holder 5, and the sealing disc 2 can be carefully removed from the collection tube 1. At this point, the collection tube 1 will contain a certain amount of saliva. The collection tube 1 can then be sent to the laboratory for testing and other follow-up operations. The entire portable oral saliva collector is designed simply and reasonably, with all components working together to efficiently and accurately complete the task of collecting oral saliva, providing reliable sample support for related medical research and diagnosis.

[0028] In some embodiments of the portable oral saliva collector provided in this application, a hygienic sleeve is detachably fitted onto the inlet 4. The hygienic sleeve needs to be removed from the end of the inlet 4 during use; the hygienic sleeve is used to prevent bacteria and other contaminants from entering the inlet 4.

[0029] The sanitary card sleeve, which can be removed after each use, effectively prevents bacteria and other harmful substances from entering the collection tube 1 through the inlet 4, ensuring that the collected saliva sample is pure and uncontaminated, providing a reliable guarantee for subsequent testing and other work. In actual operation, the user only needs to simply swing the bracket 5 to engage the timing device, and then remove the sanitary card sleeve from the inlet 4 to easily begin the saliva collection process. The entire process is convenient and quick, greatly improving the efficiency and quality of saliva collection.

[0030] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 1 and Figure 2An defoaming net 8 is installed on the lower surface of the sealing disc 2. The defoaming net 8 eliminates air bubbles in the upper part of the saliva as the sealing disc 2 moves downwards. When saliva is collected into the collector 1, the defoaming net 8 effectively reduces the presence of air bubbles. This is because some air bubbles may be generated during the flow of saliva into the collector due to factors such as flow. The special structure of the defoaming net 8 can disrupt the surface tension of the air bubbles, causing them to gradually break down and disappear. This results in purer collected saliva, free from excessive air bubble interference. This is significant for subsequent saliva testing and analysis. For example, when detecting components in saliva, the absence of air bubbles prevents them from affecting the accuracy and stability of the test results. When measuring the concentration of certain substances in saliva, the presence of air bubbles may cause deviations in measurements such as light absorption, thus affecting the reliability of the final results. The defoaming net 8 maximizes the accuracy of the test results, providing more reliable data support for oral health research and disease diagnosis.

[0031] When the occlusion disc 2 moves downwards, it fits tightly against the inner wall of the collection tube 1, effectively collecting the saliva adhering to the inner wall to the bottom of the collection tube 1. The push rod 3 facilitates operation for medical personnel or users; a gentle push of the push rod 3 precisely controls the up-and-down movement of the occlusion disc 2. As the occlusion disc 2 descends, the amount of saliva in the collection tube 1 gradually increases. Once a certain amount is reached, subsequent testing can be performed. The support 5 is oscillating on the collection tube 1. When the timing clip is attached to the support 5, it accurately records the saliva collection time and other relevant data, providing accurate timing data for subsequent testing and analysis. This portable oral saliva collector is simple to operate, rationally designed, and efficiently completes saliva collection, providing reliable sample support for medical diagnosis and other procedures.

[0032] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 1 and Figure 2 A push rod 3 is fixed to the occlusion disc 2. Moving the push rod 3 causes the occlusion disc 2 to move upwards, and vice versa, thus collecting saliva from the inner wall of the collection tube 1. Since the patient doesn't remain completely still, some saliva will always adhere to the inner wall. The push rod 3 is inserted into the occlusion disc 2. When needed, the push rod 3 is simply inserted into the occlusion disc 2. The outer wall of the collection tube 1 has graduations, which clearly indicate the amount of saliva inside, allowing the user to easily monitor the collection progress.

[0033] The vent valve is a one-way vent valve, allowing only air to enter the collection tube 1 in one direction, preventing external impurities from entering, and ensuring air pressure balance within the collection tube 1, which is conducive to smooth saliva collection. The inlet nozzle 4 is funnel-shaped, with its larger end connected to the collection tube 1 and its smaller end facilitating accurate saliva flow into the collection tube 1, improving collection efficiency. The collection tube 1 is made of transparent plastic, allowing users to directly observe the saliva collection process. The transparent material is easy to clean and disinfect, and is reusable. The bracket 5 is connected to the collection tube 1 via a pivot, allowing the bracket 5 to swing flexibly for quick and accurate engagement of the timing device.

[0034] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 1 and Figure 2 A sealing gasket is attached to the outer edge of the sealing disc 2. This gasket, made of elastic material, fits tightly against the inner wall of the collection tube 1, effectively preventing saliva from leaking out through the gap between the sealing disc 2 and the inner wall of the collection tube 1. As the sealing disc 2 slides within the collection tube 1, the sealing gasket moves accordingly, maintaining a consistent seal. This sealing design ensures no leakage of saliva within the collection tube 1 during saliva collection, improving accuracy and efficiency. Furthermore, the elastic material of the sealing gasket provides flexibility, preventing damage from the sliding of the sealing disc 2 and ensuring stable sealing performance over long-term use. Simultaneously, the sealing gasket helps reduce the entry of outside air into the collection tube 1, preventing saliva contamination. It not only provides a physical seal but also maintains a stable environment within the collection tube 1, providing a reliable guarantee for accurate saliva collection and testing. In practical use, the user simply places this portable oral saliva collector in the mouth correctly, and the saliva is collected completely and without contamination within the collection tube 1.

[0035] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 1 and Figure 2 A vent valve is installed through the sealing disc 2. The vent valve is a one-way valve to prevent the entry of external impurities. Additionally, the inlet nozzle 4 is designed with an arc shape for easy contact with the oral cavity, and its material is soft and skin-friendly medical-grade silicone to improve user comfort during saliva collection. Furthermore, the connection between the inlet nozzle 4 and the collection tube 1 is sealed to prevent saliva from overflowing during collection.

[0036] For ease of carrying and storage, a protective sleeve is fitted onto the outer wall of the collection tube 1. The protective sleeve is made of a plastic material with a certain degree of elasticity. The protective sleeve not only prevents the collection tube 1 from being damaged by collisions during carrying, but also provides a certain degree of anti-slip effect, making it easier for the user to hold.

[0037] In addition, this portable oral saliva collector comes with a storage box, inside which are specially designed recesses for holding the various components of the collector. The storage box is made of hard plastic, which has good pressure resistance and wear resistance, effectively protecting the various components of the collector and preventing damage during storage and carrying.

[0038] In some embodiments of the portable oral saliva collector provided in this application, the inner wall of the inlet 4 is provided with an anti-adhesion coating. This coating facilitates the rapid flow of saliva. In actual use, saliva enters the collection tube 1 from the inlet 4, and due to the anti-adhesion coating on the inner wall of the inlet 4, the saliva smoothly slides to the bottom of the collection tube 1. When a timing device is needed, it can be attached to the bracket 5 for convenient timing of the saliva collection process. Thus, the entire portable oral saliva collector, through the coordinated action of its components, can efficiently and accurately complete the saliva collection process, providing convenience for subsequent testing and other operations.

[0039] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 2 The bracket 5 includes a first rod 7 hinged to a second rod 6, the first rod 7 being hinged to the collection tube 1, and a locking block being hinged to the end of the second rod 6 away from the first rod 7.

[0040] In use, the timing element is engaged with the locking block, and its spatial position can be easily adjusted by swinging the first lever 7 and the second lever 6. Furthermore, a torsion spring is provided at the hinge point between the first lever 7 and the collecting tube 1, which keeps the first lever 7 horizontal in its natural state. Thus, after adjusting the timing element's position by swinging the first lever 7, releasing the first lever 7 allows it to automatically return to a horizontal position under the action of the torsion spring, facilitating a quick return to the appropriate initial state for the next use.

[0041] The second rod 6 has multiple positioning holes near the first rod 7, and the first rod 7 has positioning pins that fit the positioning holes. After the timing element is adjusted, the positioning pins can be inserted into the corresponding positioning holes to fix the relative positions of the first rod 7 and the second rod 6, making the timing element more stable and preventing it from changing position due to shaking during saliva collection.

[0042] The locking block is rectangular, and its curvature matches the outer perimeter of the timing component, allowing it to securely hold the timing component and prevent it from falling off during collection. At the same time, the surface of the locking block has an anti-slip texture, increasing friction with the timing component and further ensuring the stability of the locking mechanism.

[0043] For some embodiments of the portable oral saliva collector provided in this application, please refer to... Figure 2 and Figure 3The locking block includes a fixing part 501 and a connecting part 502. The fixing part 501 is hinged to the second rod 6, and the connecting part 502 is slidably disposed on the fixing part 501. The fixing part 501 and the connecting part 502 cooperate to lock the timing device. By sliding the connecting part 502 and the fixing part 501, the distance between them is changed, ultimately facilitating the locking of different timing devices. After saliva collection is completed, the time spent on saliva collection can be accurately determined based on the time recorded by the locked timing device, providing accurate data support for subsequent testing and other operations.

[0044] This portable oral saliva collector, with its flexible snap-on timing function and reasonable internal structure design, can meet the timing needs of different patients during the saliva collection process, greatly improving the efficiency and accuracy of saliva collection, and providing a powerful tool for oral-related medical research and diagnosis.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
