The saliva collecting device provided by the present invention includes a liquid storage tube 1, a collecting tube 2, and a dropper 3. The liquid storage tube 1 is used to store saliva. The liquid storage tube 1 includes a pressing portion 11. The collection tube 2 is detachably installed in the liquid storage tube 1. The collection tube 2 includes a collection unit 21, and a collection port is provided in the collection unit 21. The dropper 3 is used to replace the sampling tube 2. The dropper 3 is formed with a suction hole 31 for sucking saliva.

The saliva collection device provided by the present invention is provided with a liquid storage tube 1, a collection tube 2, and a dropper 3, so that the liquid storage tube 1 is filled with a diluted solution, and the collection tube 2 is connected to the liquid storage tube 1. When the saliva is collected, the saliva is diluted in the liquid storage tube 1. Further, when the collection tube 2 is removed, the dropper 3 is connected to the liquid storage tube 1, and the liquid storage tube 1 is pressed, saliva is sucked out from the dropper 3. As described above, the saliva collecting device can complete the collection, processing and suction of saliva and is easy to use.

Specifically, an opening is opened at one end of the liquid storage pipe 1. The collection pipe 2 can be connected to the liquid storage pipe 1 by a method such as screwing or hooking. The collection port of the collection tube 2 communicates with the opening of the liquid storage tube 1. The dropper 3 can be connected to the liquid storage pipe 1 by a method such as screwing or hooking. The suction hole 31 communicates with the opening of the liquid storage pipe 1.

In addition, the pressing portion 11 may be installed on the entire liquid storage pipe 1, or the pressing portion 11 may be installed on a part of the liquid storage pipe 1. For example, in some embodiments, the liquid storage pipe 1 may have a cylindrical shape, and the pressing portion 11 may be installed on the bottom surface of the cylinder or on the side wall of the cylinder. By pressing the pressing portion 11, the volume of the liquid storage tube 1 is reduced, and saliva inside the liquid storage tube 1 is pushed out. An elastic plastic material can be used for the pressing portion 11 so that pressing and restoration can be easily performed.

In some embodiments of the present invention, the saliva collection device comprises a protective cap 33. The protective cap 33 is detachably installed on the dropper 3. The protective cap 33 is used to seal or open the suction hole 31. By connecting the dropper 3 to the liquid storage tube 1 and sealing the suction hole 31 with the protective cap 33, the saliva stored in the saliva collecting device can be isolated from the external environment, and the saliva can be stored in a sealed manner. .. For example, as shown in FIG. 5, in some embodiments, the dropper 3 is molded with a tapered head portion. The shape of the protective cap 33 is provided so as to match the head portion of the dropper 3, and the suction hole 31 is sealed by covering the head portion of the dropper 3 with the protective cap 33. The inner wall of the protective cap 33 is firmly installed on the dropper 3 by firmly pressing the outer wall of the dropper 3. Needless to say, in some other embodiments, the protective cap 33 may be installed on the dropper 3 by a method such as screwing.

In some embodiments, the protective cap 33 is molded with a first protrusion. The first protrusion is provided so as to fit into the suction hole 31. In some cases, foreign matter such as food residue in saliva may remain at the outlet position of the suction hole 31, and saliva may not be sucked out smoothly. Such a situation is more likely to occur when the diameter of the outlet of the suction hole 31 is small. However, when the protective cap 33 is installed in the dropper 3, if the first protrusion is inserted into the suction hole 31, foreign matter that may remain at the outlet position can be pushed out by the first protrusion, so that saliva is sucked out. Becomes smooth. In addition, in some embodiments, the sealing effect of the protective cap 33 can be improved by firmly locking the first protrusion to the suction hole 31.

In some embodiments of the present invention, the dropper 3 is provided with a filter 32. A structure such as a filter net, a filtration membrane, and a filter plate can be adopted for the filter 32. Since the filter 32 can filter foreign substances in saliva, the risk of clogging of the suction hole 31 is reduced. For example, as shown in FIG. 5, a filter plate is adopted as the filter 32. The filter plate has several through-holes, and by adjusting the number and size of the through-holes, the filtration parameters can be flexibly changed, and the saliva suction speed can also be adjusted.

In some embodiments of the present invention, the size of the collection port is larger than the size of the liquid storage tube 1. By increasing the size of the collection port, saliva can be easily collected, and the usability of the saliva collection device is improved. For example, as shown in FIGS. 2 and 3, the diameter of the collection port is larger than the diameter of the liquid storage tube 1, and saliva can be easily discharged to the collection port at the time of collection.

In some embodiments of the present invention, the sampling tube 2 includes a buffer section 22. A spout is provided in the buffer portion 22. The spout is in communication with the collection port. The liquid storage pipe 1 is provided with a sealing portion 12. The sealing portion 12 is used to seal or open the spout. When collecting saliva, the collection tube 2 is inserted into the opening of the liquid storage tube 1, and the spout is sealed by the sealing portion 12. The collected saliva is stored in the buffer unit 22, and the saliva and the diluted solution in the liquid storage tube 1 are separated by the sealing unit 12. After collecting an appropriate volume of saliva, the collection tube 2 is removed and the sealing portion 12 is separated from the spout. Then, saliva flows into the liquid storage tube 1 from the spout and is mixed with the diluted solution.

In some embodiments, the sealing portion 12 is molded with a second protrusion. The second protrusion is used to be inserted into the buffer portion 22. As shown in FIG. 3, when the sealing portion 12 closes the spout, the second protrusion extends into the buffer portion 22. It is possible to determine whether or not the collected saliva has reached a desired volume based on the degree of submersion of the second protrusion by saliva.

In some embodiments, the liquid reservoir 1 comprises a first segment 13 and a second segment 14. A partition is provided between the first segment 13 and the second segment 14, and the sealing portion 12 is installed in the partition. In some embodiments, the partition is provided with at least one communication hole. The communication hole communicates the first segment 13 and the second segment 14. For example, as shown in FIG. 3, the first segment 13 is located at the bottom of the liquid storage pipe 1. A diluent is stored in the first segment 13. When the collection tube 2 is removed, the sealing portion 12 is separated from the spout. Then, saliva first flows into the second segment 14 from the spout, then flows into the first segment 13 through the communication hole, and is mixed with the diluted solution. In some embodiments, the divider is removable and can be installed in the liquid storage tube 1. By processing the partition and the liquid storage tube 1 separately at the time of producing the saliva collecting device, the complexity of the processing is reduced.

In some embodiments of the present invention, a transparent or translucent material is used for the liquid storage tube 1. Further, a scale is installed on the liquid storage pipe 1. The scale can be used to read the volume of the diluent or the volume of the mixture of diluent and saliva.
