Abstract

(57) [Summary] [Objective] The purpose of the present invention is to eliminate the anxiety of a patient by infection by simply disinfecting the intraoral or other therapeutic device 10 immediately before use. A device for disinfecting a medical treatment instrument in which a chemical solution is jetted into a sterilization chamber 6 by a Venturi tube 1 to form a chemical liquid spray atmosphere 5 in the sterilization chamber 6, and a treatment instrument insertion port 7 is opened in the sterilization chamber 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disinfection device such as an intraoral treatment instrument.

[0002]

[Prior Art]

 Conventionally, disinfection and sterilization of a cutting bar attached to the tip of a dental handpiece has been performed by separating the bar from the above handpiece and immersing it in an antiseptic solution.

It has been difficult to disinfect the bar attached to the handpiece in front of the patient's eyes and immediately before inserting it into the oral cavity.

Therefore, there is a problem that the patient's anxiety about disinfection cannot be eliminated, and it is difficult to disinfect each time the oral cavity is inserted.

[0005]

[Problems to be solved by the device]

 The purpose of the present invention is to obtain a treatment instrument disinfection device that can disinfect, sterilize, or sterilize not only dental instruments but also other treatment instruments in the oral cavity immediately before use, and can eliminate anxiety of patients.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention connects the narrow portion of the Venturi tube and the inside of the chemical liquid tank with a liquid sending pipe, connects the pressure pipe to the base end of the Venturi pipe, and connects the tip of the Venturi pipe with a chemical liquid spray atmosphere. A treatment instrument disinfection device which is directed to the sterilization chamber and has a treatment instrument insertion port opened in the sterilization chamber. The treatment instrument disinfection device is constructed by connecting a pressure trachea to an air compressor through an air filter.

[0007]

[Action]

 In the present invention, when the filtered air is pressure-fed from the pressure air tube 4 through the air filter 8, the chemical solution 11 in the chemical solution tank 2 is sucked from the solution feeding tube 3 which is opened to the narrow portion 1 ′ of the venturi tube 1, and this is sterilized in the sterilization chamber 6 A spray atmosphere 5 of the chemical solution 11 can be filled in the sterilization chamber 6 by spraying in a spray state.

In that state, when the treatment instrument 10 is inserted into the sterilization chamber 6 through the insertion opening 7, the spray particles of the drug solution 11 are attached and diffused to the surface of the treatment instrument 10 by surface tension, and the instrument 10 is sterilized. Therefore, it can be taken out from the sterilization chamber 6 and used for the affected area.

[0009]

【Example】

 The insertion port 7 of the treatment instrument 10 is opened at the tip of the cylindrical sterilization chamber 6, and the tip of the Venturi tube 1 is opened 1 ″ at the center of the base plate. The upper end of the liquid pipe 3 is opened and connected, and the pressure pipe 4 is connected to the base end of the Venturi pipe 1.

The lower end of the liquid supply pipe 3 is connected to the inside of the chemical liquid 11 in the atmosphere open chemical liquid tank 2, and 70% ethyl alcohol solution is used as the chemical liquid 11, but the invention is not limited to this. It is possible to use a chemical solution.

The pressure air pipe 4 is connected to the air compressor 9 with an air filter 8, a pressure adjusting valve 4 ′, a three-way valve (switching valve) 4 ″ and a receiver 9 ′ interposed, and a relay switch provided at the insertion port 7. When the switch 18 is pushed by the device 10, the solenoid 19 is actuated thereby to open the three-way valve 4 ″ and send clean compressed air to the venturi pipe 1. When the clean compressed air is sent to the venturi pipe 1, the chemical liquid is fed from the liquid feed pipe 3 to the narrow portion 1 ′. 11 can be sucked and ejected into the sterilization chamber 6 to form the spray atmosphere 5 in the chamber 6. This state is maintained by the timer for the set time (several seconds).

Although the sterilization chamber 6 is provided in the horizontal direction, the sterilization chamber 6 may be in the vertical direction. Reference numeral 12 in the drawing denotes a bypass pipe connecting the pressure pipe 4 and the liquid feeding pipe 3, 13 is a spray diffusion plate, 14 is a dental handpiece, 15 is a cutting bar, 16 is a coagulant liquid discharge port, 17 Is a chemical spray release blocker.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it has the benefit of being able to easily disinfect the treatment tool 10 in the oral cavity and the like immediately before use to prevent infection and eliminate anxiety of the patient.
