Description

DEVICE FOR SIALOGRAPHY OF SALIVARY GLANDS.

The device relates to medicine, namely to dentistry.

Currently, in the diagnosis of diseases of the salivary glands, in particular, salivary stone disease, sialography is used, which consists in retrograde filling of the gland through the duct with radiopaque material with the subsequent acquisition of x-rays.

H. Jaensch et al. Proposed polyethylene catheters that can follow the bends of the excretory duct (Jaensch N. Technick und Moqlichkeiten radiomanometrischer Speicheldrusenuntersuchunqen mit dem trijodierten Kontrastmittel Triopac, Arch. Ohr.-, Nas.-u. Kehl. 172, S. 180-220).

The closest analogue is a sterile two-gram syringe, on the cannula of which they put on a regular injection needle (of various sizes) with a blunt end (S. N. Kasatkin, "X-ray examination of the salivary glands. J." Dentistry, 1947, v. 2, p. 44-45).

The method of introducing a contrast medium according to this method has certain disadvantages. It is impossible to accurately determine the amount of contrast medium injected due to the lack of sealing of the duct, and this technique is also inconvenient for fractional sialography (V.V. Neustroev, 1965; Komrumpf, I960) With this modification, the contrast medium is administered in 2 to 3 doses of 0 , 3 - 0.5 ml in increasing quantity with the manufacture of a series of images. The disadvantages of these devices are:

1) the lack of sealing between the metal needle, catheter and the surface of the mouth of the excretory duct with the introduction of water-soluble contrast agents that have high fluidity compared to fat-soluble;

2) the need for the participation of the patient in sialography for fixation and sealing of the catheter at the mouth of the excretory duct using the index finger.

The objective of the invention is to conduct high-quality sialography with less inconvenience to the patient.

IPC A61B6 / 02

The device for sialography of the salivary glands consists of a flexible elastic tube 5 (external, internal), connected at one end to the needle (1) by means of a clamp (2), at the other - an adapter (and plug) for a syringe, the needle is made without a sharp tip and on A diplen plate (3) is installed in front of the latch (dimensions 1.0 x 1.5), which helps to prevent the reverse current of the contrast medium. Diplen "Dental-L company" Nord Ost is a medical self-adhesive film intended for the treatment of diseases of the oral cavity.

Before sialography, the mouth of the excretory duct is expanded using special graduated probes, after which a needle is inserted into the mouth until the self-adhesive diplen plate is firmly glued to the mucosa in the area of the mouth of the duct.

The amount of contrast agent administered varies with the gland under study. For the parotid gland from 2.5 to 4.5 ml, for the submandibular from 1.5 to 3.5 ml of contrast medium.

Criteria for filling the gland were mild bursting in the gland and dull pain. The patient is asked to clamp the tube between the front teeth, after which radiography is performed, with high-quality images, the device is removed, and if necessary, a contrast agent is added and radiography is performed again. We used Omnipack, a water-soluble contrast medium, since Iodolipol, a fat-soluble one, has several disadvantages. Diplen in this case is a sealant, and also has anti-inflammatory, antibacterial, analgesic effects.

Device Advantages:

1. convenient for fractional sialography;

2. promotes complete sealing of the mouth of the duct without the help of the patient (without holding the device with your fingers);

3. control over the consumption of the substance;

4. convenience for the patient;

5.Convenient to the doctor;

6. the possibility of additional administration repeatedly with insufficient filling of the gland.
