Technical Field
[0001] The utility model relates to the technical field of introduction devices, in particular to a gas anesthetic introduction device. Background Technique
[0002] Gas anesthetics, namely inhaled anesthetics, can enter the lung tissue through the respiratory tract or an anesthesia machine, and act on the brain after metabolism to inhibit the central pain-sensing nerves. A relatively large amount of inhaled drug is required to achieve the anesthetic effect. The most commonly used inhaled anesthetic drugs at present are halothane-based, such as sevoflurane, which is characterized by having an aromatic smell and being easily accepted by children. Children will cooperate with inhalation during anesthesia, which is beneficial to the smooth completion of the operation and has a relatively small psychological impact on children.

One side of the injection tube 9 is connected to a scale 10. A piston 11 is installed inside the injection tube 9. A push rod 12 is connected to the piston 11. One end of the push rod 12 is connected to a hanging plate 13. A through groove is opened in the hanging plate 13. The outer wall of the injection tube 9 is connected to a housing 15. One end of the housing 15 is connected to an elastic band 16. The elastic band 16 passes through the through groove of the hanging plate 13. One end of the elastic band 16 is connected to a clamping block 17. One end of the housing 15 is integrally formed with a buckle 18. A card slot is opened in the buckle 18. The clamping block 17 is matched and clamped in the buckle 18. When it is necessary to perform gas anesthesia on a patient, the gas anesthetic is introduced into the injection tube 9. One end of the injection tube 9 is pulled by the hanging plate 13 to move the piston 11 inside the injection tube 9, and the gas anesthetic is stored in the injection tube 9. One end of the injection tube 9 is clamped to one end of the air duct 2. The regulating valve 3 on the air duct 2 is closed. The elastic band 16 is pulled to snap the clamping block 17 into the buckle 18, and the elastic band 16 pulls the hanging plate 13 to provide elastic force to push the piston 11. The breathing mask 1 is buckled on the patient's mouth and nose, the regulating valve 3 is opened, and the quantitative flow rate is adjusted to quantitatively introduce the gas anesthetic in the injection tube 9 into the air duct 2. The air duct 2 is accurately guided to the patient's nasal cavity through the two arc-shaped guiding tubes 4, so that the gas anesthetic is quickly and quantitatively and evenly introduced into the patient's body. The quantitative gas anesthetic in the injection tube 9 is automatically and evenly and directionally introduced, the introduction operation is convenient, and the use effect is good.
[0024] Preferably, as Figure 1 and Figure 3 shown, a rubber strip 5 is embedded and connected to the bottom of the breathing mask 1. The inside of the rubber strip 5 is hollow. The rubber strip 5 at the bottom of the breathing mask 1 is in flexible contact with the patient. The hollow rubber strip 5 inside has greater elastic deformation and softer contact.
