Description

Technical Field

[0001] The utility model relates to the technical field of anesthetic gas removing equipment, in particular to an anesthetic gas removing device. Background Art

[0002] During general anesthesia surgery, if anesthetic gas is used for anesthesia, there is a possibility of malignant hyperthermia. Once malignant hyperthermia occurs, the anesthetic gas must be stopped from entering the patient's lungs as soon as possible. When the existing anesthesia machine is in use, even if the anesthetic gas vaporizer of the anesthesia machine is turned off, there is no anesthetic gas in the air intake pipe in the breathing circuit, but when the patient exhales, the gas contains anesthetic gas, because the patient's breathing back and forth is repeatedly inhaled into the lungs. Even if the flow rate of fresh anesthetic gas is increased, a large amount of gas containing anesthetic gas will still re-enter the patient's lungs.

[0003] In theory, the best effect is to quickly replace an anesthesia machine without anesthetic gas. However, since most hospitals do not have the conditions to spare an additional anesthesia machine, it is more practical to clear the anesthetic gas in the breathing circuit as soon as possible. For this reason, we designed an anesthetic gas clearing device. Utility Model Content

[0022] See also Figure 1-3 The utility model provides an anesthetic gas removal device, including a base 1, an electric push rod 2 is fixedly connected to the top of the base 1, a bracket 3 is fixedly connected to the top of the telescopic end of the electric push rod 2, a reaction chamber 4 and a drying chamber 5 are fixedly connected to the top of the bracket 3, and an air inlet interface 10 and an air outlet interface 11 are fixedly connected to the ends of the reaction chamber 4 and the drying chamber 5 that are away from each other, respectively, and are connected to the patient's exhalation side of the anesthesia breathing circuit and the port with an exhalation mark on the anesthesia machine, so as to facilitate the reaction and absorption of the anesthetic gas exhaled by the patient.

[0023] The reaction chamber 4 and the drying chamber 5 are connected by an air pipe, and the bottom of the curtain 8 extends into the alcohol 9, so as to wet the curtain 8 and remove the anesthetic gas after the gas is absorbed by the alcohol 9 on the curtain 8. A lid 7 is arranged on the top of the reaction chamber 4, a curtain 8 is arranged inside the reaction chamber 4, alcohol 9 is arranged inside the reaction chamber 4, three positioning frames 12 are arranged inside the drying chamber 5, and drying cotton 13 is fixedly connected inside the three positioning frames 12. A slide rail 14 corresponding to the positioning frame 12 is arranged inside the drying chamber 5, and a colored substance that changes color when exposed to water can be embedded in the drying cotton 13. When the drying cotton 13 is wet, it is convenient for the staff to check the drying cotton 13 through the observation window 6 and open the lid 7 to pull out the positioning frame 12 to replace the drying cotton 13.

[0024] When in use, first connect the electric push rod 2 to the external power supply, pour a sufficient amount of alcohol 9 from the water inlet valve on the top of the reaction chamber 4, connect the air inlet interface 10 to the patient's exhalation side of the anesthesia breathing circuit, and connect the air outlet interface 11 to the port with the exhalation mark on the anesthesia machine.

[0025] The gas exhaled by the patient first enters the reaction chamber 4 filled with alcohol 9. The alcohol 9 is a blue liquid. The curtain 8 is immersed in the alcohol 9 to ensure that the curtain 8 is fully immersed in the alcohol 9. The curtain 8 immersed in alcohol 9 can absorb the anesthetic gas flowing through.

[0026] After the anesthetic gas reacts in the reaction chamber 4, it enters the drying chamber 5 through the trachea, and at this time, the gas without anesthetic gas or the gas containing a certain amount of alcohol 9 enters the drying chamber 5. After the moisture is absorbed by the multi-layer drying cotton 13, the wet gas is dried, and the alcohol 9 or moisture containing the anesthetic gas is completely removed.

[0027] Since the whole device is heavy, the device has a separate, liftable bracket 3, which is convenient for driving the whole device to rise and fall through the electric push rod 2.

[0028] In this embodiment, observation windows 6 are embedded and fixedly connected to the outer walls of the reaction chamber 4 and the drying chamber 5, so that the staff can observe the curtains 8 and drying cotton 13 in the reaction chamber 4 and the drying chamber 5 and judge whether they need to be replaced.

[0029] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
