BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conditioner for an agar impression material for adjusting an agar impression material used for dental technics to an appropriate temperature, and in particular, to a temperature while holding the agar impression material in a special cartridge or syringe. Conditioner to adjust.

[0002]

2. Description of the Related Art An agar impression material used in the field of dental technics is once heated to about 100 ° C. and melted (melting step), and then cooled to a temperature for maintaining appropriate fluidity, for example, about 60 ° C. Then, it is kept warm (mooring process) and used for use. Then, such an agar impression material is usually subjected to the melting step and the anchoring step in a state of being housed in a dedicated cartridge or syringe, and in business, insert the cartridge placed in the anchoring step into the syringe, Alternatively, it is used by directly squirting it from a syringe provided in the mooring process to the main part. For this reason, some conditioners for melting and mooring the agar impression material while always storing the agar impression material in a cartridge or syringe are used for taking an impression.

[0003] For example, one of them is to set up a plurality of cartridges or syringes containing an agar impression material in a water tank storing water, and heat and cool the stored water to heat a group of syringes.・ It is of a configuration that keeps warm. As another configuration, a plurality of cartridges or a holder portion on which a syringe is erected is formed of a thermally conductive metal block such as aluminum, and the metal block is heated and cooled to control the temperature of the cartridge. A group or syringe group is heated and kept warm.

[0004]

However, any of the above conditioners has the following problems. That is, in the former conditioner using an aqueous medium, water having a large heat capacity becomes a heating medium in any of the dissolving and mooring steps, so that it takes too much time for heating or cooling, and the cartridge or syringe after the mooring step. When using, water droplets adhere to these outer surfaces, which must be wiped each time, which is complicated, that the stored water must be replaced at an appropriate time, and that the stored water is complicated. This included problems in use and hygiene, such as improper replacement if neglected.

The latter configuration using a metal block has been devised to improve the conditioner using the above-mentioned stored water. However, since the configuration is also heated through the heat conduction of the metal, the time required for melting and mooring is reduced. Required.

Therefore, the problem to be solved by the present invention is as follows.
It is a method of dissolving and mooring without using stored water or a metal block, and an object of the present invention is to provide a conditioner for an agar impression material that can shorten the time required for dissolving and mooring.

And a tray section (83) that is detachably fitted into the second section (2) and supported by its peripheral edge (81) to close the opening. The tray portion (83) is further provided with a plurality of concave portions (84) projecting downward in a substantially cylindrical shape.
4) is opened leaving a peripheral portion that can support the flange portion (32) of the syringe (31), and each concave portion (84) forms a syringe holder portion (3) for standing the syringe (31). ing. As shown in FIG. 3, the tray portion (83) may be provided with a notch (85) so that the finger hook (34) of the syringe (31) can be inserted. With such a configuration, it is possible to replace the plurality of syringes (31) with the plurality of syringes (31) standing just by replacing the tray section (83).

The temperature control means (7) includes a thermocouple (71) provided near the plate heater (5) for detecting the ambient temperature near the plate heater (5), and a microcomputer. A power control unit (72) controls the melting and mooring process by controlling the temperature based on the detection output of the thermocouple (71) and measuring the time. The control section (72) has a built-in process program section capable of controlling the temperature at an intended temperature and time. The power control unit (72) includes:
A timer mechanism that can turn on and off the operation of the conditioner at an intended time may be provided, and an alarm means or a display unit for notifying the end of the process may be provided.

Each agar impression material stored in (31) is a plate heater (5)
As a result, it is possible to immediately contact the hot air immediately after being heated, thereby shortening the heating time. For example, the boiling temperature (100 ° C.) can be reached in about 10 minutes, and the agar impression material in the syringe can be used in about 30 minutes in the shortest.

[0026]

According to the present invention, since water is not used as a heating medium, there is no need to exchange water every time or wipe a syringe after each use, and to exchange or wipe water. It is a very simple and hygienic conditioner without any hygiene problems caused by forgetting. Since a plate heater is installed between the airflow source and the agar impression material to be heated, the hot air immediately contacts the agar impression material and rises along the agar impression material, so that the hot air can be effectively used. It can be used, and the agar impression material can be used in a short time. The agar impression material portion accommodated in the syringe is accommodated in the hot air chamber, and the handle portion of the syringe is located outside the hot air chamber, so that the agar impression material can be mainly heated. In addition, with such a configuration, the handle portion of the syringe is not heated and the heat loss can be reduced. Furthermore, since the finger holder of the syringe does not become hot, the operator's finger does not become hot during use.
