Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present application, the present application will be further described in detail with reference to the accompanying drawings and examples, it being understood that the specific examples described herein are for illustration only and are not intended to limit the present application.
Referring to fig. 1, the present application provides a saliva collector comprising a collecting nozzle 1 and a receptacle 2 connected thereto; the collecting nozzle 1 is connected with the inner space of the container 2 through a pipeline; wherein the collecting nozzle 1 is used for collecting saliva in the mouth of a patient and flowing the collected saliva into the container 2 for storage.
Referring to fig. 2, 3 and 4, the collecting nozzle 1 has a flat nozzle structure, which is convenient for a patient to hold the mouth of the collecting nozzle 1, realizes complete fitting of the mouth of the patient and the collecting nozzle 1, and is convenient for collecting saliva (avoiding saliva from flowing out from the corners of the mouth), and the inner space of the collecting nozzle 1 is divided into a stimulating bin 41 for placing the tongue of the patient and a circulating bin 42 for collecting saliva by the partition plate 3 inside the collecting nozzle 1; the side wall (upper side wall) of the stimulation bin 41, which is attached to the tongue taste sensitive part, is provided with a stimulation layer 5, and the stimulation layer 5 can be provided with a block structure for promoting saliva secretion according to the sensitivity of the individual tongue, such as sugar blocks formed by condensing edible acidic liquid (e.g. citric acid). The inside of the stimulating bin 41 is a closed space, through the arrangement, saliva is prevented from flowing into the stimulating bin 41 through the tongue and is mixed with the material of the stimulating layer 5, and enters the container 2, so that the accuracy of saliva detection is affected; the circulation bin 42 is arranged at the lower end of the stimulation layer 5 and is communicated with the container 2.
During the collection of saliva, the mouth of the patient holds the mouth of the collection nozzle 1 and extends the tongue into the stimulation chamber 41, after which the tongue taste sensitive portion (typically the upper part of the tongue or the tip position) is brought into contact with the stimulation layer 5. The tongue and brain are stimulated by the stimulation layer 5 and salivary secretion is promoted. The secreted saliva lies from the lower edge of the tongue (the sublingual mons, sublingual gland site) into the circulation bin 42 and further into the receptacle 2.
Preferably, the stimulating layer 5 of the present application is disposed on an insert 51, and the side wall of the stimulating bin 41 is provided with a slot 52 for installing the insert 51. Through the detachable installation of the stimulation layer 5 of above-mentioned structure realization, can change the kind of stimulation layer 5 according to user's saliva stimulation degree on the one hand, another convenient can carry out sealed treatment (place stimulation layer 5 and inserted block 51 in sealed bag) to stimulation layer 5 before the device uses, avoids causing the pollution to stimulation layer 5, influences oral hygiene.
The container 2 is internally provided with a bottle bin 61 for placing the negative pressure collecting bottle 6, the bottle bin 61 is internally provided with a sponge fixing layer 10 for assisting in fixing the negative pressure collecting bottle 6, and the position of the negative pressure collecting bottle 6 is fixed through the sponge fixing layer 10.
