Description

The utility model relates to medicine, in particular to the section of pediatric maxillofacial surgery, and can be used to treat atresia of the palatopharyngeal ring [А61С 7/02, А61С 8/00].

The prior art Implanted support for the soft palate [EP 2332496 (A1), publ. 06/15/2011], characterized in that it consists of a connecting end of the hard palate, having a connecting structure that can be connected to the hard palate and a support, which is a flat implant that can be inserted into the soft palate, while the connecting end the hard palate and the support are rigidly connected or connected with the possibility of detachment. The disadvantages of analog are

this solution is aimed at the treatment of apnea syndrome and is not suitable for the elimination of atresia of the palatopharyngeal ring;

titanium was chosen as the implanted material, which increases the cost, increases the cost of the device design;

the implanted support for the soft palate is implanted in the human body, which complicates the treatment process.

Also known from the prior art is a Palatal holder with an attached nasopharyngeal airway extension for the treatment of obstructive sleep apnea [US 2018353322 (A1), publ. 12/13/2018], consisting of a fixing device made with the possibility of removable attachment to the patient's jaw and a displacing element. The disadvantages of this analogue are

this solution is aimed at the treatment of apnea syndrome and is not suitable for the elimination of atresia of the palatopharyngeal ring;

the presence of a wire with memory, a cylinder, and other elements in the design greatly complicates the design and reduces safety when installing and wearing the device.

The prior art also known Obturator for closing the defect of the hard and soft palate [WO2020141449 (A1), publ. 07/09/2020], containing a hard plate replacing the hard palate for closing a defect of the hard palate, characterized in that it contains an inflatable, in particular, semi-inflated soft element with a flexible outer shell, located next to the hard plate and having a part replacing the soft palate, coming out beyond the end of the rigid plate replacing the palate. The disadvantages of this analogue are

the design of the device does not provide the ability to eliminate atresia of the palatopharyngeal ring;

to attach a soft element to a hard one, magnets are used that have a constant electromagnetic effect on the human body;

electrodes are used in the palate implant, and an electrode control unit is implanted in the temporal region, which can negatively affect the cerebral cortex;

the design of the device is quite complicated, which increases the installation process of the device, as well as the duration of treatment of patients.

The closest in technical essence is a device for eliminating atresia of the palatopharyngeal ring [MAMEDOV A.A. et al., Speech obturators as an alternative to surgical elimination of palatopharyngeal insufficiency in patients with speech disorders, Pediatric Dentistry and Prevention, 4(67) 2018, pp. 74-79], containing a plate made with the possibility of its fixation in oral cavity, a full-bodied obturator connected to the plate by means of a fastener, while the size of the obturator corresponds to the size of the palatopharyngeal ring.

The main technical problem of the prototype is that when using the known device, it is impossible to provide oral-nasal breathing, which negatively affects the general somatic health of the patient, and it is also impossible to ensure the outflow of mucus from the nose into the oral cavity, which will lead to the development of inflammatory processes in the pharynx.

The purpose of the utility model is to eliminate the shortcomings of the prototype.

The technical result of the utility model is to reduce the rehabilitation time for pediatric patients with atresia of the palatopharyngeal ring, to achieve a stable positive result in restoring oronasal breathing, which, as a result, has a positive effect on the overall somatic health of the child.

The specified technical result is achieved due to the fact that the device for eliminating atresia of the palatopharyngeal ring contains a plate made with the possibility of fixing it in the oral cavity, a full-bodied obturator connected to the plate by means of a fastener, the size of the obturator corresponds to the size of the palatopharyngeal ring, and a hole is made in the obturator for the passage of air.

Brief description of the drawings

In FIG. 2 shows a side view of the device with an obturator.

The drawings indicate: 1 - plate, 2 - hook loops, 3 - fastener, 4 - obturator, 5 - hole for air passage.

Implementation of the utility model

The device for eliminating atresia of the palatopharyngeal ring contains a fixing plate 1, made with the possibility of its fixation in the oral cavity with the help of hook loops 2 for the teeth of the upper jaw. Attached to the posterior edge of the plate 1 is a fastening element 3, at the distal end of which a full-bodied rounded obturator 4 is fixed, the size of which corresponds to the size of the palatopharyngeal ring (not shown in the figures). An opening 5 is made in the obturator 4 for the passage of air.

A device for eliminating atresia of the palatopharyngeal ring is used as follows.

Initially, an impression is taken from the upper jaw to make a plaster model of the upper jaw, on the basis of which a fixing plate 1 with hook loops 2 for the teeth of the upper jaw is made. From the rear edge of the fixed plate 1, a fastener 3 is attached from orthodontic wire. At the distal end of the fastening element 3, a rounded obturator 4 is attached, the size of which corresponds to the size of the expanded palatopharyngeal ring planned before the surgical operation. When this obturator 4 prevents pathological scarring of postoperative tissues. The obturator 4 is worn by the patient constantly throughout the day and is removed only for hygienic treatment. After 2-3 weeks of use, a hole 5 is made in the obturator 4 to allow air to pass through the nose.

After achieving stable anatomical and functional results, the device is removed and no longer worn.

Thus, the use of a device to eliminate atresia of the palatopharyngeal ring can reduce the rehabilitation time for pediatric patients with atresia of the palatopharyngeal ring and preserve oronasal breathing, which, as a result, has a positive effect on the general somatic health of the child.

The technical result of the utility model is to reduce the rehabilitation time for pediatric patients with atresia of the palatopharyngeal ring and achieve a stable positive result in restoring oronasal breathing, which, as a result, has a positive effect on the general somatic health of the child, is achieved due to the fact that the device is used to eliminate atresia of the palatopharyngeal ring, comprising a plate made with the possibility of its fixation in the oral cavity, a full-bodied obturator connected to the plate by means of a fastener, the size of the obturator corresponds to the size of the palatopharyngeal ring, and a hole is made in the obturator for air passage.

Claims (1)

A device for eliminating atresia of the palatopharyngeal ring, comprising a plate made with the possibility of fixing it in the oral cavity, a full-bodied obturator connected to the plate by means of a fastener, the size of the obturator corresponding to the size of the palatopharyngeal ring, characterized in that the obturator has a hole for air passage.
