Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention is a vaporizer for inhalation anesthesia, especially an anesthesia i for vaporizers.
Concerning improvement of injection/discharge equipment.

(DE US Technology) In recent years, inhalation anesthesia has been mostly used for general anesthesia due to the ease of controlling the anesthetic effect.

Inhalation anesthesia is performed by vaporizing a volatile anesthetic solution in a vaporizer using a gas such as oxygen or suboxide that flows through the vaporizer, and then inhaling the mixture into the patient.

Conventionally, in order to inject and discharge anesthetic solution into this anesthesia 11-J vaporizer, remove the screw thread of the vaporizer and inject the receiver into the mouth until the vapor reaches a certain level. Inject the anesthetic solution, loosen the screw at the bottom of the vaporizer, and let the anesthetic solution in the vaporizer drain naturally into the empty tube placed below. I was doing it.

This injection/ejection force method does not require special q:I loading,
Although it is convenient, there is an unavoidable risk of injecting one citrus anesthetic solution into a vaporizer that should be dedicated to each anesthetic solution.

If you mistakenly inject the anesthetic system of the song to the special anesthetic solution vaporizer, or if you use Ike's type of anesthetic solution to the % anesthetic solution remaining in the vaporizer from Mu. If the supplementary light 11 is mixed and appears dangerous, there is a strong possibility that the name of the image will be at risk, and sometimes it may even lead to fatal consequences.

In order to avoid such external dangers, methods are used to call attention to the use of the film using signs, etc., indicating the color of each anesthetic solution, but in order to prevent mistakes, There is a need for a device that allows the association of anesthetic solution containers of "Physically Wisdom, Ll" to be used only with a dedicated vaporizer.

For this reason, fill the silkworm in the anesthetic solution container exclusively for fi
The end can be connected to the inlet of a special vaporizer by connecting it to the injection port of a special vaporizer, and the anesthetic solution can be connected to the inlet of a special vaporizer by using a special connecting tube that cannot be connected to the anesthetic inlet of the pond or the vaporizer. A drum box that injects and discharges water has been proposed.

(Special Publication No. 48-8197) However, this device is very expensive!
I! Separate body for injecting and discharging liquid I7) Delayed flexibility!
The anesthetic solution remaining in the connecting tube evaporates after V use, and the anesthetist nearby can inhale it. The problem is that it cannot be prevented from happening.

(Purpose of the Invention) This invention, without any particular reference to the song, is intended to provide a vaporizer with a specific anesthesia fI1. The words of Tanishi can be connected,
The present invention aims to provide an injection/discharge device that enables injection and discharge of anesthetic solution through a simple operation, and in which there is little residual Q solution at the connecting portion.

(Structure of the Invention) One embodiment of the injection/discharge device for a vaporizer according to the present invention will be described in detail with reference to the drawings.

The figure shows a cross-sectional view of the anesthesia device connected to the injection/discharge device of the vaporizer. Reference numeral 1 is a decoupling liquid cap, the screw-type cap is removed, and it is screwed into the force-fitting eye 11 of the discharge path switching pulse 3. #The arm Lu1l has a shape that matches the % constant container with 0 openings, so different anesthesia devices of citrons will not be housed.

The passage switching valve 3 is rotatably attached to a valve case 4 provided on the 1141j wall of the vaporizing main body 12, and two gas-liquid passages 8.9 are exposed therein, and the valve case 4 is rotatably attached to the valve case 4 provided on the wall 1141j of the vaporizing main body 12.
to the upper O blood passage 6, and to the lower passage 7 to the lower part (Fig. 3).
A groove 5 extending into each bottle 1 is fixed to the side end of the passage 8V communicating with the opening 11.

Passage switching in valve case 4) (Lk in 2 v of lube 3)
A gas-liquid passage 6.7 leading to the vaporization b12 is accommodated in correspondence to the gas passage 8.9 in the gas g passage 8.9, and the passage 6.7 and the passage 8
．． 9 is a rotary nozzle (communicated or shut off by loop 2). The above-mentioned vaporizer is shown as below. 0 is a storage container containing an anesthetic solution, and the opening is at its mouth. It is screwed into the attachment/detachment port 11 which has a shape of υ, and the state shown in Fig. 1 is reached. (Fig. 2) This causes the anesthesia g in the device 1 to be discharged through the passage 9.7 and injected into the vaporizer. At the same time, the air in the vaporizer passes through the passage 6%8.
, ``Through Eve 5, the 0 liquid υ in the vaporizer 10 rises in γI-i!fl, and by blocking the passage 6v, the flow of 9 air into the container 1 is stopped, The injection of anesthetic solution into the vaporizer is also stopped.

Therefore, the injection of liquid into the vaporizer will stop at a fairly constant level. If the rotary nozzle 2 is rotated to close the communication between the passage 6.8 and the passage 7.9, the communication between the carburetor body 12 and the container 1 will be closed, and in the unlikely event that L7) The anesthesia ridge will not rise above the specified level.

When storing the anesthetic solution remaining in the vaporizer in the valley Li, insert the container 1 into the attachment/detachment port 11 as shown in Fig.
Screw it on and keep it hanging.

Then rotate rotary valve 2 to open circuits 6.9 and 1.
When the outlet passages 7 and 8 are communicated, the anesthetic solution in the vaporizer flows through the passage 7.
．． 8 and pipe 5 into the container 1, while the desired air in each container 1 flows through the passage 9.6ejh into the vaporizer.

In the above actual 1l VC, V container 1 at the time of injection and discharge.
Ti rotated 180 degrees and was in an inverted position,
In reality, it may be slanted by 20 to 30 degrees, and therefore the range of motion may be 120 degrees. It must be possible to close the air-liquid passage of
Needless to say, it won't happen.

(Effects of the invention) The vaporizer of this invention does not have the above configuration, ■ Attachment/detachment port i
iSpecific V) Since it only fits with the opening of the vinegar solution numbered container, there is no danger of injecting other anesthetic solutions.

■ Since injection can be performed directly to the passage switching valve provided on the side wall of the vaporizer, and no special member for the pond is required, management is easy.

■ Two air-liquid passages are provided to separate the ηL of m vinegar solution and the associated air υ outflow, so inflow and outflow are smooth, and by blocking the sudden air passage, the chemical liquid automatically releases mulberry B.
I7) The system level at the time of injection is maintained at a constant level.

■ Two passages can be connected by the rotary valve, and the airtightness of the vaporizer can be maintained, while achieving remarkable effects such as heating.
