Description

The utility model relates to medical equipment and can be used for feeding children with congenital pathology of the palate.

Devices for feeding children are known. An example of such devices is a device containing two communicating hollow chambers, the first of which is made in the form of a mouthpiece with an outlet channel located at the top of the chamber, and the second chamber is provided with a flange for connection to a container containing liquid (US 4834099 A, 30.05.1989).

The mouthpiece of the known device does not have a flat bevel on the outer surface, which does not allow the device to be used for feeding children with a cleft palate.

A design containing two communicating hollow chambers, the first of which is made in the form of a mouthpiece with an outlet channel located at the top of the chamber and with a beveled flat surface for the child's tongue, and the second is equipped with a flange for connection to a container containing liquid (US 8708174, 04/29/2014), can be considered closer to a utility model.

The disadvantage of the known device is its unsuitability for convenient and safe feeding of children with cleft palate due to the uniform rigidity of the entire structure and incomplete overlap of the palatine cleft when the mouthpiece surface is attached to the palate. The task, to which the utility model is aimed, is to create a specialized device that ensures convenient and safe feeding of children with such a congenital pathology as cleft palate.

The technical result of the utility model is to prevent liquid from entering the respiratory tract when feeding a child with a cleft palate.

The essence of the utility model is expressed in a set of essential features, in which the device for feeding children with a cleft palate contains two communicating hollow chambers, the first of which is made in the form of a mouthpiece with an outlet channel located on the top of the chamber, on the edge of a beveled flat outer surface for adjoining the tongue, located on the surface of the chamber opposite the surface of the first chamber, made for adjoining the palate with overlapping the palatine cleft, wherein the second hollow chamber is made in the form of a liquid accumulator and is provided with an air valve in the form of a cross-shaped cut on a flat section of the outer surface, located at the entrance of the second chamber, made with a flange for hermetically sealed connection with a container containing liquid, wherein the flange is connected to the second chamber by the first neck with a wall thickness no less than twice the wall thickness of the second chamber, connected to the first chamber by the second neck, having an oval-shaped cross-section and exceeding the wall thickness of the first chamber by no less than 1.5 times.

In particular cases of its implementation or use, the device may contain a first neck with a wall thickness of 3 mm, a second chamber with a wall thickness of 1.5 mm, and a second neck with a wall thickness of 2 mm.

The technical result of the utility model is ensured by the implementation of a device in which the outlet channel of the mouthpiece is located at its top, on the edge of the beveled flat outer surface, made for adjoining the tongue.

The arrangement of the outlet channel and the edge of the flat surface for the tongue at the top of the mouthpiece with the execution of the outlet channel directly on the edge of the flat surface forces the child to press the mouthpiece to the palate with the tongue and cover the palatine gap. The reliability of covering the palatine gap is ensured by the ratio of the thicknesses of the various parts of the utility model, which allows for differentiated rigidity of the various parts of the structure while maintaining the operational properties associated with infant feeding.

The ratio of the thicknesses of the various parts of the utility model is determined by the fact that the pressure of the child's jaws on the second neck, which has an oval cross-section and a thickness exceeding the wall of the first chamber by at least one and a half times, is greater than the pressure of the tongue on the mouthpiece, pressing it against the cleft palate.

The air valve is made in the form of a cross-shaped cut on a flat section of the outer surface at the entrance of the second chamber, which ensures air entry into the second chamber and safety of feeding due to its shape. When the walls of the second chamber are deformed, which usually occurs when the position of the hand holding the container with liquid changes, the cross-shaped cut maintains the functionality of the valve and allows the child to take normal sips even when the second chamber is screwed.

The implementation of the second chamber inlet with a flange for hermetically sealed connection with a container containing liquid, and the connection of the flange with the second chamber by the first neck with a wall thickness no less than twice the wall thickness of the second chamber, is due to the fact that when connecting the second chamber to the container, the flange and, accordingly, the walls of the device are stretched with significant force.

Since the entire device is made of one material as a single whole and the parts of the device experience different loads, the optimal solution is to make its walls in certain ratios established experimentally for a certain pathology. Making the device with walls whose thicknesses are interconnected allows manipulations with the device without interrupting the process of safe feeding due to the flexibility of the thinner walls of the device while maintaining the rigidity of the walls that are thicker.

The essence of the utility model is explained by a drawing, in which Fig. 1 shows an isometric view of a device for feeding children with a cleft palate, Fig. 2 shows a side view of the device, Fig. 3 shows a rear view, Fig. 4 shows a front view, and Fig. 5 shows a longitudinal section of the device.

The device for feeding children with a cleft palate contains two communicating hollow chambers 1 and 2. The first chamber 1 is made in the form of a mouthpiece with an outlet channel 3 located on the top of chamber 1 and has a flat beveled outer surface 4 made for adjoining the child's tongue, and a back spatula-shaped surface 5 made for adjoining the palate with overlapping the palatine cleft. The outlet channel 3 is located on the edge of the beveled flat outer surface 4. The second hollow chamber 2 is made in the form of a liquid accumulator and is provided with an air valve 6 in the form of a cross-shaped cut 11 on a flat section 7 of the outer surface, located at the entrance of the second chamber 2. The entrance of the second chamber 2 is made with a flange 8 for a hermetically sealed connection with a container containing liquid. The flange 8 is connected to the second chamber 2 by the first neck 9 with a wall thickness no less than twice the wall thickness of the second chamber 2. The second chamber 2 is connected to the first chamber 1 by the second neck 10, which has an oval cross-section and a thickness no less than one and a half times the wall thickness of the first chamber 1.
