Description

Mask anesthesia device

This creation relates to a mask-type anesthesia device, in particular a mask-type anesthesia device that retains the vent gas and circulates it.

The mask-type anesthesia device is a medical tube that is often used during surgery, and is used to deliver an anesthetic gas supplied by an anesthetic source to a patient's mouth and nose for inhalation by a patient. A mask-type anesthesia device comprises a mask, an air supply tube and an exhaust tube. The mask covers the mouth and nose of the patient, and the air supply tube connects the anesthetic gas source to deliver the anesthetic gas to the mouth and nose of the patient. The gas exhaled after inhaling the anesthetic gas is discharged through the exhaust pipe to the mask anesthesia device. Since the gas exhaled by the patient after inhaling the anesthetic gas still contains a part of the anesthetic gas, another conventional mask-type anesthesia device has a connecting tube between the air supply pipe and the exhaust pipe, and the disease is connected through the connecting tube. Part of the exhaled gas is recycled and reused to save medical resources.

Since the recovered patient's exhaled gas mixes with the anesthetic gas provided by the anesthetic source, the dose concentration is changed, so all anesthesia needs cannot be applied. Therefore, it is quite inconvenient for the skill to prepare different mask-type anesthesia devices for different anesthesia needs.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The purpose of this creation is to provide a mask-type anesthesia device that retains the vent gas and circulates it.

In order to achieve the above object, the present invention provides a mask type anesthesia device comprising a breathing mask, an air inlet passage, an exhaust passage, a gas storage bag and a circulation tube. One end of the intake passage is connected to the breathing mask. One end of the exhaust passage is connected to the breathing mask. The air bag is connected to the exhaust passage. The circulation pipe is connected to the intake passage and the exhaust passage.

Preferably, the aforementioned mask type anesthesia device has an exhaust port at the other end of the exhaust passage.

Preferably, in the aforementioned mask-type anesthesia device, the circulation tube is provided with a wake-up ball.

Preferably, in the above-mentioned mask type anesthesia device, the circulation tube is provided with a refreshing ball, and the awakening ball is disposed near the exhaust port.

Preferably, in the aforementioned mask type anesthesia apparatus, a carbon dioxide removing unit is disposed in the circulation pipe.

Preferably, in the above-described mask type anesthesia apparatus, the circulation pipe is connected to the exhaust passage corresponding to the position of the air bag.

Preferably, in the above-mentioned mask type anesthesia device, a one-way air valve is provided on the intake passage for the air outside the intake passage to enter the intake passage.

The mask-type anesthesia device of the present invention retains part of the exhaust gas in the air bag and can be selectively recycled. Therefore, this creation can be adapted to different anesthesia needs than conventional mask anesthesia devices.

Referring to the first figure, a preferred embodiment of the present invention provides a mask-type anesthesia device for connection between a patient and an anesthetic source to thereby supply an anesthetic gas 10 to the patient. In the present embodiment, the mask-type anesthesia device of the present invention comprises a breathing mask 100, an intake passage 210, an exhaust passage 220, an air bag 300, and a circulation tube 400.

Referring to the second and third figures, the respiratory mask 100 is used to cover the mouth and nose of a patient. The intake passage 210 is tubular, one end of the intake passage 210 is connected to the respiratory mask 100, and the other end is connected to the anesthetic gas source. The anesthetic source is a positive pressure source that provides an anesthetic gas 10 in which the anesthetic is mixed with oxygen. Preferably, a one-way air valve 211 is disposed on the outer side of the intake passage 210, and the one-way air valve 211 is configured to allow air outside the intake passage 210 to enter the intake passage 210. When the supply of the anesthetic gas source is interrupted, the patient can take in air from the outside of the intake passage 210 through the one-way air valve 211 of the intake passage 210. When the anesthetic source is supplied, the one-way valve 211 is closed by the positive pressure of the anesthetic source.

The exhaust passage 220 has a tubular shape, and one end of the exhaust passage 220 has an exhaust port 221, and the other end thereof communicates with the respiratory mask 100. Preferably, one end of the intake passage 210 and one end of the exhaust passage 220 are constituted by a pipe body 200 (but the intake passage 210 and the exhaust passage 220 may also be disposed separately, and are not limited thereto). One end of the tubular body 200 communicates with the respiratory mask 100, and the inside of the tubular body 200 is provided with a spacer 201 which extends along the radial direction of the tubular body 200, thereby separating the tubular body 200 into two isolated tubular spaces. An intake passage 210 that communicates with the respiratory mask 100 and an exhaust passage 220 that communicates with the respiratory mask 100 are formed. Preferably, at the other end of the tubular body 200, the intake passage 210 and the exhaust passage 220 are disposed in a divergent manner.

The air bag 300 is in communication with the outer side of the exhaust passage 220, and is preferably disposed adjacent to the exhaust port 221. The circulation pipe 400 has a tubular shape, and its two ends are respectively communicated with portions of the intake passage 210 and the exhaust passage 220, and the two ends of the circulation pipe 400 are preferably communicated with the intake passage 210 and the exhaust passage 220, respectively. The side is connected between the intake passage 210 and the exhaust passage 220. Preferably, the circulation pipe 400 is connected to the outer side surface of the exhaust passage 220 corresponding to the position of the air bag 300. A carbon dioxide removing unit 410 is disposed in the circulation pipe 400. In addition, the circulation tube 400 may further be provided with an awakening ball 420. The awakening ball 420 is preferably connected to the outer side surface of the circulation tube 400, and the air outside the mask type anesthesia device can be passed through the circulation tube by pressing the recovery ball 420. 400 is pressed into the intake passage 210.

Referring to the third and fourth figures, the mask-type anesthesia device of the present invention delivers an anesthetic gas source to the respiratory mask 100 through the air inlet passage 210 for inhalation by the patient, and the patient inhales the anesthetic gas 10 and exhales the exhaust gas 20. The anesthetic agent and oxygen contained in the anesthetic gas 10 are not completely absorbed by the patient after being inhaled by the patient. Therefore, the exhaled gas 20 exhaled by the patient contains a part of the anesthetic agent and oxygen, and the patient also absorbs oxygen. The carbon dioxide produced.

Referring to the fifth figure, when the exhaust gas 20 flows along the exhaust passage 220 to the air bag 300, a part of the exhaust gas 20 flows into the air bag 300 and remains therein, and the remaining exhaust gas 20 passes through the exhaust gas. The vent 221 of the channel 220 exits the masked anesthesia device of the present invention.

Referring to the sixth figure, the exhaust gas 20 remaining in the air bag 300 can be squeezed into the intake passage 210 through the circulation pipe 400 by squeezing the air bag 300. The exhaust gas 20 passes through the carbon dioxide removing unit 410 in the circulation pipe 400 to remove carbon dioxide contained therein, and the exhaust gas 20 from which carbon dioxide is removed is mixed with the anesthetic gas 10 in the intake passage 210 and then sent to the respiratory mask 100 for recycling.

The present invention can recover and retain part of the exhaust gas 20 in the air bag 300 by the air bag 300 and the circulation pipe 400, and can be selectively recycled, thereby effectively improving the disadvantages of the prior art.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of the patents of the present invention. Other equivalent variations of the patent spirit using the present invention are all within the scope of the patent.
