Description

Technical Field

[0001] The present invention relates to the field of mixing, and particularly to an anesthetic agent proportioning and mixing device for the anesthesiology department. Background Art

[0002] During general anesthesia surgery, the patient inhales a mixed gas mainly containing anesthetic drugs and oxygen. These gases play a crucial role during the surgery. Anesthetic drugs such as isoflurane and sevoflurane achieve general anesthesia by inhibiting the central nervous system. They can quickly put the patient into an unconscious state, ensuring that the patient does not feel pain during the surgery. Oxygen is essential for maintaining the patient's life. During the surgery, to ensure the patient's oxygenation, the mixed gas will contain a certain proportion of oxygen to prevent respiratory depression caused by anesthesia. To ensure the quality of the anesthetic mixed gas, a proportioning device is used to mix with oxygen when the medicament evaporates, reducing the evaporation of the medicament while slowing down the loss of the medicament temperature and improving the mixing effect of the anesthetic gas and oxygen.

[0003] After retrieval, a Chinese patent application with the publication number CN119056286A discloses an anesthetic agent proportioning and mixing device for the anesthesiology department, including a bottom plate. A oxygen cylinder and a medicine storage box are fixedly connected to the upper side of the bottom plate. The top of the oxygen cylinder is fixedly connected with an oxygen delivery pipe. One end of the oxygen delivery pipe extends into the medicine storage box. A solenoid valve is provided on the oxygen delivery pipe, and the solenoid valve is used to control the flow rate of oxygen in the oxygen delivery pipe. An anesthetic is provided in the medicine storage box. A first heater is provided at the bottom of the medicine storage box. A gas guide cylinder is fixedly connected to the upper side of the medicine storage box, and the gas guide cylinder is communicated with the inside of the medicine storage box. A gas guide and mixing device is provided inside the spiral blade. The top of the gas guide cylinder is fixedly connected with an air outlet pipe. The present invention adjusts the power of the first heater and the second heater and the opening and closing of the solenoid valve according to the temperature, humidity, and concentration values of the anesthetic mixed gas, thereby ensuring the quality of the anesthetic mixed gas and ensuring the actual anesthetic performance.

[0004] When mixing the medicament and oxygen, the medicament is usually filled into the evaporation tank, and the medicament is evaporated by the evaporation tank. The evaporated medicament will come into contact with the input oxygen, and the medicament and oxygen are mixed by stirring. However, during the stirring process, since the medicament has humidity when evaporating, the weight of the evaporated medicament will be greater than the weight of oxygen, resulting in a poor mixing effect between the medicament and oxygen.

[0011] Preferably, an air jetting mechanism is arranged at the bottom of the stirring mechanism, and the air jetting mechanism forms a cooperation with the stirring mechanism.

[0012] Preferably, the jet mechanism is composed of a plurality of second nozzles. A first cavity is formed inside the turntable, and a second cavity is formed inside a plurality of stirring blades. An inlet is formed through one side of the second cavity, and one end of the inlet is inclined.

At this time, the oxygen and the agent will act on the stirring blade 24, and the oxygen and the agent will be centrifuged while rotating, so as to facilitate the equal mass of the agent and the oxygen, preventing the weight of the evaporated agent from being greater than the weight of the oxygen due to the humidity during the evaporation of the agent during the stirring process, resulting in a poor mixing effect between the agent and the oxygen. When the oxygen and the agent act on the stirring blade 24, the oxygen and the agent will be conveyed into the second cavity 26 through the inlet 29, conveyed into the second nozzle 28 through the connecting pipe 27, and the oxygen and the agent will be conveyed downward through the second nozzle 28. Since the heights of the multiple second nozzles 28 are different, when the turntable 23 rotates, the airflow range ejected by the multiple second nozzles 28 will gradually increase from top to bottom, and the airflow will flow in a vortex shape. At this time, the airflow will contact the evaporated agent, and the agent will flow in a vortex shape under the action of the airflow, so as to facilitate the treatment of the evaporated agent through the action of the airflow, so as to facilitate the treatment of the humidity of the agent, facilitate the mass of the agent to be close to the mass of the oxygen, so that the oxygen and the agent are fully mixed, and further improve the preparation effect of the agent.
