Nasopharyngeal anesthesia spray pot

Abstract

The invention discloses a nasopharyngeal anesthesia spray pot which comprises a pot. The pot is provided with a spout, a pot lid is arranged on the spout and is hermetically connected with the spout,a high-pressure tube and a medicine spray tube are arranged on the pot lid, penetrate the pot lid to extend into the pot and are hermetically connected with the pot lid, a high-pressure gas tank is connected with the end, which is positioned outside the pot, of the high-pressure tube, a switch valve is arranged on the high-pressure tube, a spray nozzle is arranged at the end, which is positioned outside the pot, of the medicine spray tube, and a mist spray cover is arranged on the spray nozzle. The nasopharyngeal anesthesia spray pot has the advantages that the nasopharyngeal anesthesia spraypot is reasonable in design; anesthetics can be atomized and sprayed to nasopharyngeal parts by high-pressure gas, the mist spray cover can prevent anesthetic gas from being diffused, and accordinglyenvironmental pollution can be prevented; the atomized anesthetic gas can be concentrated at anesthesia parts, accordingly, anesthetic effects can be improved, and the usage amount of the anestheticscan be saved; the atomized gas can be sprayed out of the pot by the aid of the high-pressure gas, and the switch valve can bring convenience for spraying the atomized anesthetics.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a nasopharyngeal anesthesia spray bottle. Background technique [0002] Inhalation anesthesia is the earliest anesthesia method used in the history of anesthesia. It is a method of general anesthesia produced by absorbing volatile anesthetics or anesthetic gases into the blood through the respiratory system and inhibiting the central nervous system. Inhalational anesthetics are less metabolized and decomposed in the body, and most of them are excreted from the lungs in their original form. Therefore, inhalational anesthesia has high controllability, safety and effectiveness. [0003] At present, inhalation anesthesia is still an important part of general anesthesia, but occupational exposure or environmental pollution caused by the leakage of inhalation anesthetics is always an unavoidable disadvantage. At present, anesthesiologists mainly use highly airtight...

Problems solved by technology

[0003] At present, inhalation anesthesia is still an important part of general anesthesia, but occupational exposure or environmental pollution caused by the leakage of inhalation anesthetics is always an unavoidable disadvantage

At present, anesthesiologists mainly use highly airtight tracheal intubation or relatively airtight laryngeal mask to perform inhalation anesthesia, but tracheal intubation or laryngeal mask have certain respiratory complications (glottic edema, laryngospasm, etc.) ) risk, especially for children
