Description

FUNCTIONAL Oral and Maxillofacial Manipulator

The utility model relates to the field of medicine, namely functional diagnostics, functional therapy, clinical psychology, rehabilitation and can be used to develop in children and parents the skills of primary self-examination and examination of the child’s chewing muscles, demonstrating massage techniques for chewing and facial muscles, developing knowledge about the anatomical -physiological device of the masticatory apparatus, increasing the level of motivation for dental treatment, creating a positive psycho-emotional pho and the child and the parents before the start of orthodontic treatment, the quality control of the treatment.

A device for training facial and chewing muscles is known (document WO2008118918, class A63B 23/03, 2008 (PCT / US, No. 2008058157), which is an elastic membrane placed on the surface of the skin. A motorized rotor brush acts on the membrane from the outside. stimulating and training muscle at the location of the membrane.

The disadvantages of the known invention: when exposed to muscle work with insufficient amplitude and load; training is not effective enough due to weak external impact; training does not contribute to the formation of skills for proper muscle work; the effect is mainly directed to a single muscle, and not to a group of muscles.

The famous simulator "Stat Baby No. 350" (http://simulaids.com/als/STATBabyBasic.htm) is a dummy made of latex for practicing medical manipulations. The dummy has anatomical signs of the head of a child 5-6 years old and can be used to train nasal and oral intubation, the possibility of pneumatic changes in the volume of the larynx and tongue.

The disadvantages of the device include: the inability to adjust the volume of the anatomical localization of the masticatory muscles; significant weight of the mannequin; the presence of latex, which is a strong allergen; the high cost of the simulator.

A device is known, which is a multilayer massage ball (US 7156817 B1), largely reflecting the characteristics of the density and deformation of the human thumb, used to reduce sensitivity and pain in the muscles, including trigger zones. A massage ball consists of a core encapsulated in several elastic layers. A massage ball can directly or indirectly affect the affected area, reducing pain or discomfort in the muscles or connective tissue structures.

The disadvantages of the prototype: the surface of the ball reflects the characteristics of only one anatomical structure, namely the thumb; the device of the ball does not allow changing its density; the sample has a high cost and is not used in pediatric clinical practice

A device is known (German Pat. No. 202005000612, class A63B 23/03, 2005), which comprises a screen in the form of a spherical segment. In front of the screen, randomly fixed colored plates that do not change their position. The device is designed to normalize the tonic state of the neuromuscular apparatus and improve the psychoemotional status of the child.

The disadvantages of the known device:

1. The static position of the colored elements. The same combination of colored elements.

2. The size of the device does not allow to fill most of the visual space with the image of colored elements.

3. There is no application of the device. In particular, for training and training.

Closest to the claimed sample is a worn “muscle” blouse (US 4310927 A), equipped with inflatable pneumatic cameras that simulate the localization of the pectoralis major muscle, external abdominal muscles, as well as the biceps of the shoulder. The cervical and sleeve protective elastic rings used for fixation are fixed to the blouse. The blouse is designed to develop a child's knowledge of the anatomical structure of the human body, and is also used for games.

The disadvantages of the known device

1. The pressure of the chambers simulating muscles does not correspond to the physiological parameters of tension and rest of similar anatomical areas;

2. The device of the pneumatic system does not allow differential supply of air into the chambers;

3. The prototype is intended solely to simulate the muscles of the chest, abdomen and upper limbs;

4. The prototype has no domestic counterparts and has a high market value.

Effect: increase the level of motivation of the child and parents to dental treatment using a device that allows you to normalize the functional state of the muscles of the maxillofacial region.

The functional manipulator is a dummy of the child’s head made of a hypoallergenic polyvinyl chloride plasticizer, for example, plastisol (Fig. 1, 2, 3).

The structural elements of the functional manipulator: the polyvinyl chloride frame shell of the manipulator (1), the upper air chambers (2), the lower air chambers (3), the upper air ducts (4), the lower air ducts (5), the central air duct (6), the base of the manipulator (7), nipple valve (8), superficially contoured chewing muscles proper (2), superficially contoured temporal muscles (10).

On the outer surface of the dummy, contours of the manipulator are outlined, corresponding to the projection onto the skin of the surface departments of the chewing and temporal muscles proper (9). Two upper (2) and two lower air chambers (3) are placed inside the manipulator, projectively localized in the regions where the above muscles are located. The volume of the lower chambers corresponds to the volume of the surface departments of the chewing muscles proper in a state of tension. The volume of the upper chambers corresponds to the volume of the front bundles of the temporal muscles in a state of tension.

The inner surface of each chamber is limited by a plastisol membrane to which the upper (4) and lower (5) air ducts are made of durable and plastic material, for example, polyurethane. The system of upper (4) and lower (5) air hoses coming from the chambers (1,2) is discharged to a central hose (6) connected to a nipple valve (8) fixed in the area of the model base (7).

The principle of operation of the manipulator is as follows. Using an electronic pressure gauge determine the initial pressure inside the chambers of the manipulator. The level of tension of the masticatory muscles in a patient is determined using a myotonometer. The density of the structure in similar areas of the manipulator (9.1 0) is measured using a myotonometer and an electronic pressure gauge. Comparison of the obtained data with known normative parameters (Persin LS, Sharov M N Dentistry, neurostomatology, dentofacial system dysfunction. Textbook / M.: GEOTAR-Media, 2013.-360 pp., Ill. Chap. 4 p. 82 -87).

Using a nipple needle, the functional manipulator is connected to a low-power electric compressor and air is pumped into the chamber of the manipulator (2, 3). The pressure recorded by the pressure gauge connected to the compressor must correspond to individual parameters characteristic of normal muscle tone in a child who is prepared for classes on this manipulator. The pressure level in the chambers (2,3) of the manipulator is determined by a myotonometer for further treatment and prevention sessions with the child. After verification of the pressure inside the dummy, the latter is passed on to the child.

In a playful form, the child is shown the device of chewing muscles, they are taught methods of training and muscle massage, they develop skills to examine their own muscles based on a comparative manual study of the areas (9, 10) of the manipulator corresponding to the localization of chewing muscles.
