Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a mouth secretion collection device. Background Art

[0002] As we all know, saliva is a complex mixture that contains not only various proteins, but also DNA, RNA, fatty acids and various microorganisms. Studies have found that various protein components in the blood are also present in saliva. Saliva can reflect changes in the levels of various proteins in the blood. Patients need to use a mouth secretion collection device to collect saliva from their mouths for testing.

[0003] In real life, common oral secretion collection devices include a test tube for collecting saliva, and a funnel threadedly connected to the upper part of the test tube. When collecting saliva, the user needs to spit the saliva into the funnel, and the saliva flows through the funnel into the test tube for collection. However, different users have different situations and different saliva viscosities. Saliva with high viscosity falls on the funnel and flows slowly into the test tube, causing the test tube to collect saliva more slowly. The device does not have a device to accelerate the flow of saliva, so its practicality is not very good and there is room for improvement. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model is a mouth secretion collection device, comprising a collection tube body 1, the upper and lower parts of the collection tube body 1 are both provided with external threads 2, the lower external threads 2 of the collection tube body 1 are threadedly connected with a cover 9, the cover 9 is unscrewed from the lower part of the collection tube body 1, and then screwed to the upper part of the collection tube body 1, the collection tube body 1 can be closed, the upper part of the collection tube body 1 is threadedly connected with a funnel 3 for collecting saliva, two liquid guide plates 4 are provided on the inner wall of the funnel 3, the middle parts of the two liquid guide plates 4 are provided with flow grooves 8, the patient spits saliva into the flow grooves 8, and then the saliva flows into the collection tube body 1, the cross-sections of the two flow grooves 8 are both arranged in an arc shape, so that the saliva gathers in the middle part of the flow grooves 8 and flows, and the right side of the funnel 3 is provided with a plurality of liquid guide plates 4. An annular clamping ring 5 is provided at the top, and a connecting rod 6 is clamped on the annular clamping ring 5. A liquid pushing block 7 is provided at the lower part of the connecting rod 6. The user grabs the connecting rod 6 and extends the liquid pushing block 7 into the flow groove 8 to push the saliva to the bottom of the funnel 3 and enter the collection tube body 1.
