DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0029] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first," "second," and "third" are used solely for descriptive purposes and to distinguish technical features. They are not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0031] In the description of this utility model, it should be noted that, unless otherwise clearly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in this utility model based on the circumstances. The following describes an embodiment of the utility model based on its overall structure.

[0032] like Figure 1-Figure 7 As shown, the saliva collection device of this embodiment includes: a collection tube 1, an internal thread 11, a measuring tube 2, a liquid inlet 21, a sampling cotton 22, a test strip 23, a fixed end seat 3, a sealing groove 31, a second clamping member 311, a liquid outlet 32, an external thread 33, a liquid outlet tube 4, a screw cap 5, a sealing sleeve 51, a handle 52, a first clamping member 53, anti-slip grooves 54 and a clamping ring 55.

[0033] Continue to refer Figure 1-Figure 7 The measuring tube 2 is preferably made of a transparent plastic material. The sampling cotton 22 is fixed to one end of the measuring tube 2. The test strip 23 is installed in the measuring tube 2. One end of the test strip 23 is connected to the sampling cotton 22. The test strip 23 is preferably a water-absorbing test paper with a measurement mark, which is set at the other end of the test strip 23. When the subject holds the sampling cotton 22 in their mouth, the other end of the measuring tube 2 is tilted downward. As the sampling cotton 22 is soaked with the saliva sample, the saliva sample flows toward the test strip 23 and gradually soaks the test strip 23, gradually revealing the measurement mark. The subject can observe the degree of exposure of the measurement mark in real time. When the measurement mark on the test strip 23 is fully exposed, it indicates that the sampling cotton 22 has fully absorbed the saliva and the collection process is complete. In addition, the sampling cotton 22 is preferably a biological sponge. The biological sponge filters out impurities in the saliva. The saliva sample absorbed by the biological sponge is relatively clear. Using a clear saliva sample for testing can ensure the accuracy of the test results.

[0034] In order to facilitate the storage of the measuring tube 2 in the collecting tube 1, a fixed end seat 3 is provided at the other end of the measuring tube 2, and an external thread 33 is provided on the outside of the fixed end seat 3. The mouth of the collecting tube 1 is provided with an internal thread 11 that is compatible with the external thread 33. When the collection work is completed, the fixed end seat 3 is threadedly connected to the mouth of the collecting tube 1. At this time, the measuring tube 2 can be installed in the collecting tube 1, and the sampling cotton 22 is abutted against the bottom of the collecting tube 1, so that the sampling cotton 22 is in a compressed state, and the saliva sample is squeezed out of the sampling cotton 22 and placed in the collecting tube 1; this can avoid the saliva sample flowing out of the collecting tube 1 when the sampling cotton 22 is squeezed, resulting in the loss of the saliva sample.

[0035] In this embodiment, the fixed end seat 3 includes a liquid outlet pipe 4, which has a liquid outlet 32. One end of the liquid outlet pipe 4 is connected to the liquid outlet 32, and the other end of the measuring tube 2 is provided with a liquid inlet 21 connected to the liquid outlet 32. The collection tube 1 is preferably made of an elastically deformable transparent plastic material. When a saliva sample needs to be taken out from the collection tube 1, the bottom of the collection tube 1 is turned upward, and the saliva sample is concentrated at the liquid inlet 21. Then, the outer wall of the collection tube 1 is squeezed by hand, and the saliva sample will flow from the liquid inlet 21 to the liquid outlet pipe 4 and then drip out of the liquid outlet pipe 4. This design is convenient for staff operation, greatly avoids the embarrassing situation that the staff will directly contact the saliva sample, and can also avoid the problem of wasting saliva samples due to excessively large pouring angles.

[0036] At this time, the outlet pipe 4 is in an open state, and impurities can easily enter the collection tube 1 from the outlet pipe 4. In order to prevent the saliva sample from being contaminated by external impurities, a detachable screw cap 5 is provided on the fixed end seat 3. The fixed end seat 3 is provided with a sealing groove 31, and the screw cap 5 is provided with a sealing sleeve 51 corresponding to the sealing groove 31. The screw cap 5 is inserted into the sealing groove 31 through the sealing sleeve 51 to be installed on the fixed end seat 3; a clamping ring 55 is provided on the outside of the sealing sleeve 51. When the sealing sleeve 51 is inserted into the sealing groove 31, the screw cap 5 is fixed in the fixed end seat 3 through the clamping ring 55, and the pipe mouth of the liquid outlet pipe 4 is located in the sealing sleeve 51, which solves the problem of the saliva sample being contaminated by impurities due to the liquid outlet pipe 4 not being closed; at this time, a rotational force is applied to the screw cap 5, and the screw cap 5 can rotate in the fixed end seat 3; if an outward pulling force is applied to the screw cap 5, the screw cap 5 can be removed from the fixed end seat 3.

[0037] The screw cap 5 is provided with at least one first clamping member 53, and the sealing groove 31 is provided with at least one second clamping member 311. When the screw cap 5 is rotated counterclockwise, the first clamping member 53 and the second clamping member 311 can interlock, continuing to provide rotational force, allowing the measuring tube 2 in the collection tube 1 to move upward from the collection tube 1, gradually separating from the collection tube 1, releasing the compressed sampling cotton 22, and allowing the saliva sample to be reabsorbed by the sampling cotton 22. When the screw cap 5 is rotated clockwise, the first clamping member 53 can still interlock with the second clamping member 311, continuing to provide rotational force and downward pressure to the fixed end seat 3, pressing the sampling cotton 22 back to the bottom of the collection tube 1, allowing the saliva sample to return to the collection tube 1. The cooperation between the first clamping member 53 on the screw cap 5 and the second clamping member 311 on the sealing groove 31 can help facilitate the insertion and removal of the measuring tube 2 into the collection tube 1.

[0038] In summary, in this embodiment, the subject holds the sampling cotton 22 in his mouth to collect saliva. During the saliva collection process, when the saliva completely soaks the test strip 23 and the measurement mark is completely revealed, it indicates that the saliva collection work is completed. The required amount of saliva collection can be accurately grasped, the collection efficiency is improved, and the collection effect is better. It solves the problem that the existing saliva collection device will collect saliva samples mixed with a lot of impurities and cannot clearly indicate the required sample amount to the subject.
