A device for measuring oral cavity pressure includes the following: a pressure measuring probe having a balloon made of an elastic material is supported by a balloon base; a communicating member having an inner bore that communicates with the inside of the balloon via the balloon base to transmit the air pressure in the balloon; and a pressure detecting unit that is connected to the rear end of the communicating member and detects the transmitted air pressure. The balloon includes a pressure receiving portion that forms a cavity and a balloon tubular portion that communicates with the inside of the pressure receiving portion, and the balloon is joined to the front end portion of the balloon base with the balloon tubular portion. The balloon base has a rib that protrudes outward along the outer circumferential direction of the front end portion on the balloon side.

Device for measuring oral cavity pressure, pressure measuring probe

A device includes: a controller that converts a pressure value detected by a pressure detector into visual or aural lingual pressure information changed depending on a magnitude of the pressure value; and an information output unit, such as a buzzer and a color display LED, that outputs the lingual pressure information in response to a signal from the controller. The information output unit outputs lingual pressure information different depending on a pressing force applied on an elastic balloon by a tongue, allowing users such as patients and elderly people to continue a training without being bored.

Disclosed herein is a probefor measuring a lip closing force, the probe including: a hollow balloonconfigured to be disposed between an upper lipand lower lipof a subject, and crushed and deformed by the lip closing force, and a basewhich is connected to a pressure measurement devicefor measuring an internal pressure of the balloon. The balloonis provided with a fixable portionconfigured to be sandwiched between teethandor gums of the subject.

An exercise toolfor improving oral function inserted and used in an oral cavity includes: a baseinserted in the oral cavity; and a hollow bulgewhich is made of an elastic body and protrudes from the base. Level difference portions-and-are provided in a vertically intermediate region of at least one of an outer surface and an inner surface of the bulge

Oral cavity function training tool

A balloon including: a pressure-receiving portion formed of an elastic material and forming an enclosed space; and a tubular portion formed integrally therewith. The balloon is configured to detect the air pressure in the pressure-receiving portion due to communication with a pressure detector through an opening end of the tubular portion. A transverse cross-section of the pressure-receiving portion orthogonal to the axial direction of the tubular portion has a flattened outer circumferential shape with an oblateness f=(A&#x2212;B)/A, where A represents the length of a major axis of the outer circumferential shape and B represents the length of a minor axis thereof, being set to a range of 0.1&#x2266;f&#x2266;0.7 at a position at which the length A is at a maximum. The air pressure can be changed significantly and stably, and the precision of the pressure measurement can be increased.

[PROBLEMS] To provide a material for producing a bioabsorbable material in which it is easy to remove a metal zinc catalyst from a bioabsorbable polymer such as a polymer of lactide or a polymer of lactide and caprolactone and it is easy to recycle the removed powdery metal zinc catalyst, and to provide a bioabsorbable material produced from the material for producing a bioabsorbable material. [MEANS FOR SOLVING PROBLEMS] A material for producing a bioabsorbable material including a three-dimensionally shaped metal zinc polymerization catalyst and a bioabsorbable polymer such as a polymer of lactide or a polymer of lactide and caprolactone; and a process for producing a material for producing a bioabsorbable material, characterized in that in the process for producing a bioabsorbable polymer by polymerization, a three-dimensionally shaped metal zinc catalyst is used as a polymerization catalyst.
