Description

  The present invention can be carried anywhere by carrying it, can be used safely and hygienically, and can carry saliva and the like sufficiently even when compressed gas with a relatively low compression rate is used. The present invention relates to a suction device such as saliva.

  With the recent aging of the population, visiting medical care is also required in the dental field. In dental treatment, it is necessary to suck saliva etc. including tooth shavings etc., but since a large special device such as an air compressor is required, the treatment content is limited in visiting medical treatment, and if it is not actually visited the hospital I was unable to treat.

  On the other hand, air compressors and the like that have been reduced in size and weight have been developed. However, it is difficult to carry and carry them, and the actual situation is that they are rarely used in visiting clinics.

  Further, in order to generate a suction force using compressed gas obtained from an air compressor or the like, a suction force generator having an ejector mechanism is required, and a compressed gas supply path through which compressed gas is supplied to the suction force generator And a suction path for suctioning and a discharge path for discharging the suctioned thing are necessary, so that a T-shaped one is suitable, and a suction force generator having such a shape is widely used. There were no dental suction force generators that were well-designed and designed to be suitable for insertion into the oral cavity.

  For such a problem, a portable and hygienic suction assisting device has an injection needle attached at one end, an opening at the other end, and a flange portion provided at the periphery of the opening. A cylindrical body, a rod-like member inserted into the cylindrical body, a head fixed to the tip of the rod-like member and moved in contact with the inner peripheral surface of the cylindrical member, and an outer end of the rod-like member A body fluid suction assisting instrument used in combination with a syringe comprising a plunger having a handle that is connected and has a portion extending laterally from the rod-shaped member, and a flange portion of the tubular member The plunger is disposed between the plunger handle and has an air inlet. When air is introduced from the air inlet, the plunger is moved away from the flange portion. Axial direction of rod-shaped member A plunger driving member to be moved; and a compressed air supply member which is connected to an air inlet of the plunger driving member and supplies compressed air to the plunger driving member by being operated manually or by a foot. There is a body fluid suction assisting device (see, for example, Patent Document 1). However, this body fluid aspiration assisting device must be aspirated from the injection needle, so it is very dangerous to use in the oral cavity, and it is difficult to aspirate when saliva contains tooth scraps. Moreover, in this body fluid suction assisting device, since the plunger of the syringe is merely pulled by compressed air instead of being pulled by hand, it is not different from simple suction by a syringe.

  In addition, as an automatic suction processor equipped with a T-shaped suction force generator, a reverse L-type injection nozzle is arranged in a T-type air gun, and the compressed air of the air compressor is reversely injected to convert the in-cylinder wind tunnel into suction force. In addition, there is an automatic suction processor that accommodates waste in a processing tank by the simultaneous action of suction and discharge (see, for example, Patent Document 2). However, since this automatic suction processor uses an air compressor, it is not suitable for dental visits, and the structure of the T-type air gun is not designed to discharge the suction downward. Therefore, when a compressed gas generation source that generates a compressed gas having a relatively low compression rate other than the air compressor is used, the suctioned gas cannot be sufficiently discharged.
