Description

Technical Field

[0001] The present invention relates to the technical field of saliva collection, in particular to a splash-proof saliva collector. Background Art

[0002] Saliva samples include multiple biomarkers such as DNA, RNA, proteins and small molecule metabolites, which can help determine the risk and diagnosis of diseases, evaluate and predict the progression and treatment of diseases, and are of great significance for the intervention and treatment of diseases. Therefore, saliva samples have broad application prospects in the field of biomedical engineering. Saliva samples require a saliva collector when collecting them. The saliva collector can not only collect saliva samples, but also ensure their stability and preservation, thereby making the analysis and research of saliva samples more reliable. Therefore, the saliva collector has an important position and application potential in the field of biomedical engineering industry.

[0003] For example, the patent name disclosed in the prior art with the announcement number "CN116509457B" is "A saliva collector for convenient extraction". It discloses that after the saliva is collected, the top of the funnel can be well sealed, the connection is firm and the sealing is good, and it will not fall off and cause the sample to overflow. In addition, because an anti-residue extraction component is provided, the saliva can be fully discharged when extracting the saliva sample to prevent a large amount of residue. In addition, because a sealing component is provided for easy docking, the docking joint at the bottom can be removed, so that the bottom of the collection tube is opened, which is convenient for cleaning the equipment. After the saliva sample is collected, the bottom plate is embedded in the funnel, and the upper torsion column is rotated so that the upper torsion column is pushed into the side groove to push the movable block, thereby compressing the inner airbag, and the internal gas enters the sealed airbag. The volume of the sealed airbag expands and then embeds into the sealing groove, which can make the connection more stable and the gap at the connection blocked, greatly improving the sealing. Sealing property. For example, the patent title disclosed in the prior art with the announcement number "CN209966431U" is "A saliva collector capable of preventing splashing". It discloses that the top of the collection tube is connected to the output end of the funnel, the inner surface of the output end of the funnel is provided with an internal thread, and the outer surface of the top of the collection tube is provided with a corresponding external thread. An rubber ring is arranged at the bottom of the external thread of the collection tube. The front of the top of the funnel is a mouth-fitting surface with a downward curved arc edge. The back of the funnel is provided with an upward protruding ventilation tube. The mouth-fitting surface is designed according to the shape of human lips. When in use, the arc edge is close to the lips, thereby preventing saliva from splashing outside the funnel and causing environmental pollution when spitting saliva into the funnel. An rubber ring is fixedly sleeved on the collection tube. The rubber ring is used to seal the connection between the collection tube and the output end of the funnel. When the collection tube is threadedly connected to the funnel, it prevents saliva from flowing out of the gap between the two due to quality defects of the collection tube or the funnel, causing environmental pollution.

[0004] The saliva collector of the prior art is used by placing the curved side of the funnel close to the lips and then spitting saliva into the funnel. Although this can prevent saliva from splashing outside the funnel and causing environmental pollution, when the saliva is spit into the funnel, some of the saliva will splash onto the skin around the lips of the user's face inside the funnel. This not only requires finding a tissue to wipe the facial skin later, but also reduces the amount of saliva sample collected, which in turn affects the subsequent biomedical engineering diagnosis of diseases. Therefore, a splash-proof saliva collector is proposed to solve the above-mentioned problems. Summary of the Invention

Therefore, the saliva collector can be used to collect body sample saliva well, so that diseases can be diagnosed through saliva analysis later, which makes the saliva collector well used in the field of biomedical engineering industry; (2) When the pressure on the air storage bag assembly stops, the piston assembly, the guide cover and the guide tube can be automatically moved downward and reset by the stored force of the reset spring, so that the piston assembly can generate a certain suction force on the area below the oral tube, thereby increasing the falling speed of the saliva in the oral tube, thereby improving the collection efficiency of the entire saliva collector; (3) The guide cover can drive the moving rod and the self-locking block to descend and reset together, so that the self-locking block and the self-locking cover can cooperate with each other, making it easier for the bottom of the self-locking block to seal the falling opening, and then automatically self-lock the inside of the oral tube to prevent the saliva from evaporating or being contaminated after collection; (4) Furthermore, the upward-moving vertical rod pushes the control plate and the auxiliary tube to move upward together, thereby squeezing the connecting hose and the connecting spring. When the vertical rod is separated from the control plate at a later time, the control plate and the auxiliary tube can automatically swing up and down for a period of time through the stored force of the connecting spring, thereby further increasing the falling speed of the saliva in the auxiliary tube and further improving the collection efficiency of the entire saliva collector.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-10 , the present invention provides the following technical solutions: Example 1: The anti-splash saliva collector in this embodiment can not only prevent saliva from splashing onto the outside of the contact cover 2, but also prevent saliva from splashing onto the skin around the user's lips during the saliva collection process, thereby avoiding the situation where the amount of saliva sample collected is reduced due to splashing. For the specific structure, please refer to the attached Figures 1-8As shown, it includes an outer tube body 1 and a contact cover 2 installed above it, a sealing block 5 is fixed to the inner side wall above the outer tube body 1, and a mouth tube 3 is fixed through the middle of the sealing block 5, and a self-locking sealing component is installed inside the mouth tube 3, and a piston assembly 6 is fitted and connected to the lower interior of the outer tube body 1, and a flow guide cover 7 is installed through the middle interior of the piston assembly 6, and the bottom of the flow guide cover 7 is connected to the upper end of the flow guide tube 8, and the lower end of the flow guide tube 8 is sealed and slidably connected to the bottom surface of the outer tube body 1, while the flow guide The lower end of the tube 8 is threadedly connected to the liquid storage tube 9, and an air guide control component is installed on the outside of the outer tube body 1. The self-locking sealing component includes a self-locking cover 14 installed inside the oral tube 3, and the self-locking cover 14 is funnel-shaped, and a drop port 141 is opened inside the bottom surface of the self-locking cover 14, and a moving rod 12 is provided inside the drop port 141, and a self-locking block 13 is fixed to the upper end of the moving rod 12, and the lower part of the self-locking block 13 is matched with the inner concave-convex part of the drop port 141, and the upper part of the self-locking block 13 is conical, and the self-locking block 1 3 is truncated cone-shaped, and the self-locking block 13 forms a lifting structure through the moving rod 12. The lower end of the moving rod 12 is set in an inverted "T" shape, and the lower end of the moving rod 12 is connected to the inner wall of the deflector 7. The moving rod 12 and the deflector 7 are lifted and lowered synchronously. The deflector 7 is located below the oral tube 3, and the maximum diameter of the deflector 7 is smaller than the diameter of the piston assembly 6. The air guide control assembly includes an air storage airbag assembly 10 installed on the outside of the upper part of the outer tube 1, and the air storage airbag assembly 10 is set in an annular shape, and the air storage airbag assembly Two "L"-shaped delivery pipes 11 are symmetrically installed below the component 10, and the lower ends of the delivery pipes 11 are inserted into the interior of the outer tube body 1, and the lower ends of the delivery pipes 11 are located below the piston assembly 6. The bottom of the piston assembly 6 is connected to the lower interior of the outer tube body 1 through a return spring 15. A support frame 4 with an open bottom is installed below the outer tube body 1, and the outer side surface of the support frame 4 is provided with through grooves 41 for air circulation at equal intervals, and the lowest point of the support frame 4 is lower than the lowest point of the liquid storage tube 9 located therein.

[0021] First, the user holds the outer tube body 1 and the air storage bag assembly 10 with his hands. At this time, the gas in the air storage bag assembly 10 enters the outer tube body 1 below the piston assembly 6 through the delivery tube 11, so that the piston assembly 6 drives the guide tube 8 and the guide cover 7 to automatically move upward to a certain position. At this time, the return spring 15 is stretched and force is stored. Since the outer side of the guide tube 8 is sealed and slidably connected to the bottom surface of the outer tube body 1 through a rubber sealing gasket, the gas will not leak through the bottom surface of the outer tube body 1. The guide cover 7 drives the moving rod 12 and the self-locking block 13 to move upward together, so that the self-locking block 13 is separated from the self-locking cover 14. Then the saliva collector is brought close to the user's face, and the outer side of the contact cover 2 is close to the skin around the user's lips. The user gathers the saliva inside the mouth with the tongue, and then inserts the oral tube 3 into the user's mouth. The user spits saliva into the oral tube 3, and the saliva enters the oral tube 3. The saliva continues to flow downward through the drop port 141 in the bottom surface of the self-locking cover 14, and then the saliva in the oral tube 3 falls into the guide cover 7 and the guide tube 8 below. Finally, the saliva falls into the liquid storage tube 9 for collection and storage. The user then holds the lower outer side of the outer tube body 1 with his hand to separate the hand from the air storage airbag assembly 10. At this time, the piston assembly 6, the guide cover 7 and the guide tube 8 are automatically driven downward and reset by the stored force of the reset spring 15, so that the piston assembly 6 generates a certain suction force on the area inside the outer tube body 1 above, thereby allowing the saliva in the oral tube 3 to flow downward quickly, thereby increasing the falling speed of the saliva in the oral tube 3, thereby improving the collection efficiency of the entire saliva collector.

[0022] When the deflector 7 moves downward to reset, it will drive the moving rod 12 and the self-locking block 13 to move downward to reset, so that the bottom of the self-locking block 13 is tightly fitted with the inner wall of the self-locking cover 14, and then the drop opening 141 opened on the bottom surface of the self-locking cover 14 is sealed by the bottom of the self-locking block 13, so that the interior of the oral tube 3 can be automatically self-locked and closed, preventing foreign matter and dust from entering the saliva collector through the oral tube 3 in the later stage, thereby preventing the saliva collected by the saliva collector from evaporating or being contaminated. The arrangement of the through groove 41 facilitates the flow of air around the outside of the liquid storage tube 9, so It is convenient to regulate the temperature of the saliva in the liquid storage tube 9 in the later stage, so that the saliva in the liquid storage tube 9 can be well placed to avoid affecting the later detection operation. When the saliva needs to be analyzed to diagnose the disease in the later stage, the liquid storage tube 9 can be taken from the bottom of the support frame 4 by hand, and then the liquid storage tube 9 is rotated to separate the threaded connection between the liquid storage tube 9 and the guide tube 8. Therefore, the saliva in the liquid storage tube 9 can be poured out for detection and analysis operations, thereby making the saliva collector very good at collecting saliva, and the saliva collector is well used in the field of biomedical engineering industry.

[0023] Embodiment 2: The anti-splash saliva collector in this embodiment can further improve the falling speed of the saliva in the oral tube 3 on the basis of embodiment 1, and can further improve the collection efficiency of the entire saliva collector. For the specific structure, refer to the attached Figure 9-10 As shown, the lower part of the oral tube 3 is connected to the auxiliary tube 32 through a connecting hose 31, and a circular regulating disk 33 is fixed to the lower outer side of the auxiliary tube 32, and two manual telescopic rods 34 are symmetrically installed on the upper surface of the regulating disk 33, and the two manual telescopic rods 34 are respectively located on the left and right sides of the auxiliary tube 32, and a connecting spring 35 is nested and connected to the upper outer side of the manual telescopic rod 34, and two vertical rods 71 ​​are symmetrically installed on the upper surface of the air deflector 7, and a regulating disk 33 is arranged above the vertical rod 71, and there is a distance between the vertical rod 71 and the regulating disk 33, and the outer diameter of the regulating disk 33 is smaller than the outer diameter of the sealing block 5.

[0024] When the piston assembly 6 drives the guide tube 8 and the guide cover 7 to automatically move upward to a certain position, the vertical rod 71 above the guide cover 7 pushes the regulating disk 33 and the auxiliary tube 32 upward together. At this time, the connecting hose 31, the manual telescopic rod 34 and the connecting spring 35 are squeezed and contracted. When the guide cover 7 moves downward to reset in the later stage, the vertical rod 71 is separated from the regulating disk 33, and there is a distance between the vertical rod 71 and the regulating disk 33. Therefore, the stored force of the connecting spring 35 automatically drives the regulating disk 33 and the auxiliary tube 32 to swing up and down for a period of time. After a period of time, the regulating disk 33 and the auxiliary tube 32 remain fixed. Therefore, by swinging the regulating disk 33 and the auxiliary tube 32 up and down for a period of time, the falling speed of the saliva in the oral tube 3, the connecting hose 31 and the auxiliary tube 32 can be further increased, and then the collection efficiency of the entire saliva collector can be further improved, thereby completing a series of tasks.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
