DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member to be adhered typified by a metal member for removing deposits such as a drug or a filler attached to a metal member of a medical device, particularly a device used in dental care. The present invention relates to an attached matter removing device.

[0002]

2. Description of the Related Art In dental care, for example, a stopper is used when applying a drug to a treatment site of a patient, shaving teeth, filling a temporary sealing material, or fixing a crown via an adhesive. Use various stainless steel instruments such as a probe, an excavator, and tweezers. And these instruments include
Since the material used for the treatment adheres, the adhered matter is removed by a washing means after use, and a good hygiene condition is maintained.

[0003] By the way, as the above-mentioned temporary sealing material and adhesive, cement having a strong adhesive force is generally used.
When such a material having a strong adhesive force adheres to the utensil , the extraneous matter is removed by an extraneous matter removing means including a dedicated cleaning device.

[0004] This washing machine is capable of collectively washing used equipment to which cement or the like has adhered by a treatment.
After immersing used equipment in a water tank containing tap water,
An ultrasonic cleaning device that automatically performs cleaning by turning on a switch is common.

[0005] The ultrasonic cleaner has a vibrator on the outer surface of a water tank, and waves are transmitted while repeatedly compressing and depressurizing the medium liquid (tap water) according to a specific frequency generated by the vibrator. A cavity is formed between the molecules at the point of change between
When this cavity is crushed, impact energy is generated (cavitation effect), and the adhering matter is dropped from the appliance by this energy. However, since the adhesive force of the cement or the like is large, the ultrasonic cleaning device alone cannot completely remove the cement or the like. Remains on the device . Therefore, at present, the residue is manually rubbed off with a metal brush.

Further, after washing, in order to prevent disease infection from the instrument , the instrument is subjected to autocure using high-temperature and high-pressure steam as disclosed in Japanese Utility Model Publication No. 3-2285.
They are sterilized and disinfected using sterilizers called soups and reused.

[0007]

However, in the above-described cleaning means, since the power of the ultrasonic cleaning device is generally low, a troublesome removal operation by manual operation is required, and the workability is poor. Have. In further washed manual, we have the case of a strong deposit adherent such as cement, easy rather than is dropping, deposits may remain
Cormorant problem also has.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide an adhering substance removing apparatus capable of facilitating removal of adhering substances and improving workability , and capable of removing adhering substances satisfactorily. Aim.

[0010] In the above construction, there is provided a sterilizing means for sterilizing the adhered member from which the adhered substance has been removed by the washing means, and this sterilizing means is constructed in common with the boiling means.

[0011]

According to the present invention, the deposit attached to the deposit is
The impact due to the boiling reduces the adhesive force, and the adhered matter with the decreased adhesive force is removed by washing.
