Description

Saliva collection device

technical field

The utility model belongs to the technical field of medical saliva collection, in particular to a saliva collection device.

Background technique

Saliva is a mixed fluid composed of salivary gland secretions, gingival crevicular fluid and mucosal exudates, which stores a large number of human oral microorganisms and local oral tissues and other parts ^of the body. ^] , 99% of human saliva is water, the organic substances are mainly salivary amylase, mucopolysaccharide, mucin and lysozyme, etc., and the inorganic substances are sodium, potassium, calcium, chlorine and thiocyanate ions. The change of saliva composition is closely related to the pathophysiological state of the body, and is regarded as the "window of human health state". Analysis of the change of saliva composition can effectively reflect the physiological and pathological state of the body ^[3] . Quantitative analysis of saliva can be helpful for the diagnosis of exocrine dysfunction diseases such as "Sjögren's syndrome". Qualitative analysis of saliva is helpful for the diagnosis and treatment of diseases in multidisciplinary diseases such as endocrine diseases by measuring the concentration of specific components in saliva.

At present, there are three most commonly used saliva collection methods in clinical practice: EP tube natural flow method, mouth rotating cotton column method, mouth chewing cotton column method ^[1] , these methods may bring long-term mouth fatigue and cotton wool residue to patients. Various discomforts in the mouth. Various cotton column collection methods require tedious operations such as centrifugation in the follow-up, so that the first clinic doctor cannot directly and intuitively judge the function of the patient's salivary glands to secrete saliva through the collection volume. Importantly, in this type of saliva collection process, since it is directly discharged from the patient's mouth or adsorbed to a cotton swab and then centrifuged, the saliva may be spilled due to the shaking of the patient or the shaking of the medical staff during collection, which cannot provide accurate saliva quantification. The analysis results may also lead to saliva contamination, and accurate and real results cannot be provided when performing qualitative tests such as subsequent bacteriological testing of saliva. The Chinese utility model with publication number CN201922196921.0 discloses a new collection tube for saliva sample collection. The invention and creation can effectively prevent splashing during the saliva collection process, but the collection tube is designed with multiple curved surfaces and flared mouths. The saliva collection hood will lead to residual saliva, which still has a certain impact on the quantitative analysis of saliva.

Due to the existing saliva collection technology, there are still the possibility of contamination during the collection process, the inaccurate qualitative and quantitative analysis of saliva, the discomfort of the patient, and the overly complicated design of the saliva collection device. In the process of diagnosis and treatment and the risks of infection of medical staff, there is an urgent need for a saliva collection device with simple design, simple operation, strong feasibility and convenient follow-up detection.

Utility model content

In order to achieve the above purpose, according to the principle of blood collection, the present invention designs a non-invasive saliva collection device that directly collects saliva through the sublingual gland. The specific scheme is as follows:

A saliva collection device, including a saliva collector, the saliva collector is composed of an interconnected suction cup, a hose and a tail needle with a protective sleeve, the suction cup is connected to one end of the hose, and the other end of the hose is connected to a tail with a silicone protective sleeve Needle.

Further, a saliva reservoir is also included, and the saliva reservoir is movably connected with the tail needle with the protective cover.

Further, the saliva reservoir is a vacuum negative pressure glass tube marked with a scale.

Further, an anticoagulant or a coagulant is added in the vacuum negative pressure glass tube.

Further, both the suction cup and the protective cover are made of silicone material.

Advantages of the utility model

The saliva collecting device of the utility model uses a negative pressure suction cup to collect saliva through the opening of salivary glands such as sublingual glands, and the collection method is simple, safe and non-invasive. The device avoids the bacteria carried on the surface of the lips and the splash of saliva caused by human factors when the saliva flows out of the mouth and lips, reduces the loss of saliva and the pollution of saliva, and avoids the operation of centrifugation in the later stage, which greatly reduces the consumption of saliva. The steps from saliva collection to inspection are changed from tedious to simple and direct, which avoids the inconvenience of saliva flowing out of the mouth and the discomfort of cotton remaining in the mouth. The patient's tolerance is better, and it is also helpful for doctors to directly judge the patient's relatedness based on the flow rate. Diseases (such as Sjogren's syndrome), and the design of each part of the device is relatively simple, the hose, tail needle and saliva collection tube are no different from the blood collection needle and blood collection tube commonly used in clinical practice, the collection method is simple, and the collection device The simplicity makes the device more convenient for later popularization and use, and is a non-invasive way to minimize contamination of saliva.

Detailed ways

The present utility model will be further explained below with reference to the accompanying drawings and specific embodiments. It should be noted that the specific embodiments do not limit the protection scope of the present utility model.

As shown in FIG. 1 to FIG. 3 , a saliva collection device provided by this specific embodiment includes a saliva collector and a saliva storage 4 , and the saliva collector mainly consists of a suction cup 1 , a hose 2 and a protective cover 5 which are connected to each other. The suction cup 1 is connected to one end of the hose 2, and the other end of the hose 2 is connected to the tail needle 3 with the protective sleeve 5. Preferably, the saliva reservoir 4 is a vacuum negative pressure glass tube marked with a scale, which uses negative pressure to automatically and quantitatively collect saliva, and can conveniently and intuitively obtain the required amount of saliva. The vacuum negative pressure glass tube is pre-added with anticoagulant or coagulant according to different detection indicators. The hose 2 is a transparent rubber tube, the suction cup 1 and the protective cover 5 are made of silicone material, and the diameter of the suction cup 1 is 5 mm. The function of the suction cup 1 is to use the negative pressure in the saliva reservoir 4 to adsorb on the opening of the patient's salivary glands (eg, the sublingual gland), and directly suck saliva from the salivary glands under negative pressure. The tail needle 3 is used to pierce the rubber plug of the saliva reservoir 4 and penetrate into the saliva reservoir.

Before collecting saliva, clean your hands first, instruct the patient to open his mouth, place the suction cup 1 at the opening of the patient's salivary gland (such as the sublingual gland), remove the protective cover 5, and pass the tail needle 3 through the rubber stopper to make the saliva collector. Actively connected to the saliva reservoir 4 . Determine the sampling amount according to the actual situation (if the saliva flow is calculated for 1min, take the sample for 1min). After the sampling, pull out the tail needle 3, put the protective cover 5 back on the tail needle 3, and remove the suction cup 1 in the patient's mouth, and the saliva reservoir The saliva in 4 is stored or sent for inspection as needed.

The whole process of collecting saliva using the saliva collection device of this embodiment is non-invasive, no foreign matter remains, and the saliva flows directly into the saliva reservoir 4 without passing through the lips. The doctor can obtain the secretion of the patient's salivary glands in time, which can be used as evidence of clinical signs. , the whole process has no secondary contact with saliva, which ensures that the properties and components of saliva are not affected by the sampling process, and can collect saliva conveniently, quickly, intuitively and accurately.
