Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vocalization device for enabling a patient who has undergone tracheotomy and is being treated with a ventilator to vocalize.

[Conventional technology]

The condition of a patient using an artificial respirator will be explained with reference to the configuration diagram in FIG.

When long-term treatment with a ventilator is required, the patient's airway is incised and a tube called CANULE 1 is inserted to secure the airway, and breathing tubes 2 and 3 from the ventilator are inserted.
It is now connected to the lungs to move air in and out of the lungs for treatment.

The above-mentioned cannula 1 has a balloon called cuff 4 attached to it.The area above this cuff 4 (towards the mouth) is called the upper airway, and the area below (towards the lungs) is called the upper airway.By inflating this cuff 4, the airway is connected to the lungs. It prevents the air being sent from escaping towards the mouth.

However, since the vocal cords are located in the upper respiratory tract, cannula 1
While using the device, positive pressure air is not sent from the lungs, making it impossible to speak7.

Therefore, it may be possible to induce vocalization by inserting an air supply tube into the respiratory tract separately from the cannula and sending air or oxygen toward the upper respiratory tract.

[Problem that the invention seeks to solve]

However, the production of sounds by humans is highly neurological and cannot be achieved simply by mechanically pumping air into the upper respiratory tract. In order to produce vocalizations, even if air is suddenly sent, the vocal cords must move accordingly, and the timing must be determined.If air is sent suddenly, the vocal cords will close, so the patient has enough It is necessary to prepare for

Furthermore, phlegm often accumulates in the upper respiratory tract, and speech cannot be produced unless this phlegm is removed by suction.

[Means for solving problems]

The present invention is a switch system in which an air supply tube provided integrally with or separately from a cannula is connected to air supply, water supply, and suction lines, and has an air supply flow rate setting volume, a suction switch, and a conversation air open/close switch at hand. It is characterized by having the following.

[Function] According to the above configuration, when a patient wants to have a conversation, he or she first operates the suction switch to perform suction for a certain period of time to suck out sputum from the upper respiratory tract, and at the same time, water is supplied to transport the sputum. Remove sputum by suction line. Next, adjust the air flow rate setting volume to suit your own condition, and then turn on the conversation air on/off switch.
By turning it OFF, you can have a conversation by supplying air in time with the timing of your vocal cords.

〔Example〕

Examples will be described below with reference to the drawings. The figure is a system diagram, and in the figure, 5 is an airway, 6 is a vocal cord, T is a cannula, and 8 is a cuff attached to this cannula, which separates the airway 5 into an upper airway 9 and a lower airway 10. Cannula 7 is an exhalation tube 11 that connects to a respirator (not shown).
．． It has 12.

Reference numeral 13 denotes an air supply tube assembled integrally with or separately from the cannula 7, which is bifurcated into two parts, and the three divided tubes 14, 15, and 16 will be described later. Connect to each line.

Reference numeral 17 is a switch system in which an air supply flow rate setting volume 18, a suction switch 19, and an air (oxygen) opening/closing switch 20 are incorporated.

21 is the conversation air (oxygen) line, pressure gauge 22,
A solenoid valve 23, an automatic flow regulator 24, a heating humidifier 25, and a solenoid valve 26 connected to the switch system 17
etc. are connected to one tube 14 which is a branch of the air supply tube 13 mentioned above. 27 is an air (oxygen) line.

Reference numeral 28 denotes a water line for transporting sputum, which is connected to a water tank 29, a pump 30 connected to the switch system 17, a solenoid valve 31, etc., and the branched tube 15. 32 is a pump operation time setting switch for the pump 30.

Reference numeral 33 designates the above-mentioned suction line, which is connected to a solenoid valve 34, a suction bottle 35, a solenoid valve 36 connected to the pump operation time setting switch 32, etc., and to the branched tube 16. 37 is a suction line.

Furthermore, the lower respiratory tract suction line 3B is connected to the upper respiratory tract suction line 33 from the middle, and if necessary, the lower lateral passage Yu is @41 eggplant? )-zu; 39 is a solenoid valve.

Next, when starting a conversation to explain the operation of this embodiment with the above configuration, when the sputum suction switch 19 of the switch system 17 is operated, the upper airway suction line 33 is used for a certain period of time, in this embodiment, approximately 1 hour. Perform the suction action for only a minute. At this time, water is sent from the sputum transport water line 28 to the upper airway suction line 33 for a certain period of time, about 5 seconds in this embodiment, to perform suction to prevent sputum from adhering to the tube 16. When the suction is completed, a notification is given by means such as a buzzer (not shown).

Therefore, the patient adjusts the flow rate setting volume 18 of the switch system 17 at hand to a predetermined value by himself/herself, and then sends air and vocalizes while matching the timing of the vocal cords by turning on and off the air opening/closing switch 20 for conversation. The loudness and sound of the voice can be adjusted according to the patient's preference by adjusting the flow rate or by turning on and off the air opening/closing switch 20 for conversation.

In addition, the gas used for the above vocalization may be air or oxygen,
A heating humidifier 25 is used to bring the temperature to an appropriate level and keep the airway moist so as not to interfere with the airways.

Further, phlegm accumulated in the lower respiratory tract 10 can be manually sucked out using the lower respiratory tract suction tube 38.

〔Effect of the invention〕

According to the present invention described in detail above, a patient wearing a ventilator can turn on and off air supply according to the flow rate of air (oxygen) necessary for conversation and the condition of the vocal cords by operating a switch system at hand. By allowing patients to freely communicate with patients, they are able to have conversations of their own free will, which eliminates the mental pressure on patients who were previously unable to communicate, giving them a great sense of freedom. This is reflected in the treatment and results in good results.

Furthermore, the air (oxygen) being supplied is heated and humidified so that it does not irritate or dry the airways. Furthermore, since air is supplied after suction of phlegm, there is no possibility that the person will become unable to speak due to phlegm clogging.
