Anesthetic guiding device with suck-back prevention function for anesthesiology department

Abstract

The anesthesiology department anesthetic guiding device with the suck-back prevention function comprises a supporting table, the lower surface of the supporting table is fixedly connected with the upper surface of a cabinet body, a containing groove is formed in the left side of the front face of the cabinet body, and an anesthetic evaporation tank is arranged in the containing groove; the output end of the anesthesia evaporation tank is communicated with the bottom end of the heat conduction pipe through a communicating pipe; according to the scheme, by arranging the anesthesia evaporation tank, the heat conduction pipe, the connecting pipe, the connecting cylinder, the conical cylinder, a flow dividing pipe, a ball body, fan blades, an air outlet nozzle, a buffer plate and a shaping hose, when the air outlet pressure in the expiration process is larger than the air pressure sprayed out of the air outlet nozzle, air enters the connecting cylinder; the sealing ball moves rightwards and makes contact with the through hole through supporting of the elastic telescopic rod and expiration pressure, sealing work of the conical barrel is achieved, and therefore the anti-suck-back effect is achieved, exhaled carbon dioxide is prevented from being sucked back into the anesthesia evaporation tank to be mixed with medicine, and accurate calculation of the administration dosage is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more particularly, to an anesthetic drug delivery device for anesthesiology with anti-sucking function. Background technique [0002] The word anesthesia comes from the Greek word narkosis, which, as the name suggests, means numbness and paralysis, and drunkenness means drunken coma. Therefore, the meaning of anesthesia is the use of drugs or other methods to temporarily lose the patient's overall or local feeling for the purpose of painless surgical treatment. It is a science that ensures patient safety and creates favorable conditions for surgery. Now, anesthesiology has become a specialized independent discipline in clinical medicine, mainly including clinical anesthesiology, emergency resuscitation medicine, intensive monitoring therapy, pain diagnosis and treatment and other related The study of medicine and its mechanism is a comprehensive subject that studies anesthesia, ana...

Problems solved by technology

[0004] (1) At present, the existing anesthetic drug-guiding device only inhales through the breathing mask when in use. Gaps are easy to appear after contact, causing the anesthetic to overflow, which also affects the effect of the medicine

[0005] (2) When the temperature of the anesthetic gas is too low due to the influence of the environment during the drug delivery process, some patients are prone to discomfort due to the inhalation of cold gas during the breathing process, and at the same time, the exhaled carbon dioxide is easily sucked back into the anesthesia evaporation tank, resulting in The mixing of drugs is not conducive to the accurate calculation of the dosage. Therefore, an anesthesia drug guide device with anti-sucking function is proposed to solve the above problems.
