Intelligent electronic oral cavity and laryngopharynx surface anesthesia atomizer

Abstract

The invention relates to an intelligent electronic anesthesia sprayer for the surface of oral and throat, belonging to the equipment of medical service, which at least comprises a medical solution bottle (4), an oil-free compressor (2), a nozzle (7), an intelligent controller (3) and a variable-frequency motor (1). The intelligent electronic anesthesia sprayer is characterized in that: an intake interface (408) of the medical solution bottle compressor, a medical solution outgoing interface (401), and an oxygen outgoing interface (403) are arranged on the medical solution bottle (4); the oil-free compressor (2), a hose for air or oxygen passing through are connected with the intake interface (408) of the medical solution bottle compressor; the nozzle (7) is communicated with the medical solution outgoing interface (401) and the oxygen outgoing interface (403); the intelligent controller (3) is used for measuring the pressure in the medical solution bottle (4) and comparing with the preset pressure value, to computer the output voltage value to control the rotational speed of the variable-frequency motor (1); the variable-frequency motor (1) is used for controlling the output work of the oil-free compressor (2) according to the output voltage of the intelligent controller (3). The intelligent electronic anesthesia sprayer has the advantages of convenient use, short operation time, controllable spray medical solution, and ability to continuously and uniformly spray foggy medical solution.

Description

technical field [0001] The invention belongs to medical equipment, in particular to an intelligent electronic oral and throat surface anesthesia sprayer. Background technique [0002] In clinical practice, when intubating the difficult airway caused by throat surgery and various reasons, in order to satisfactorily suppress the laryngeal reflex, fully expose the throat, and smoothly carry out the tracheal intubation operation, give sufficient support. Topical anesthesia is essential. The surface anesthetic sprayer currently used clinically is a throat sprayer, and the method adopted is the direct spray method, that is, the required local anesthetic is injected into the container in advance, and the skin bag is squeezed during use, and the liquid is sprayed from the straight tube nozzle of the instrument to the patient's throat department. During the operation, usually an anesthesiologist uses a laryngoscope to expose the tissue structure of the oral cavity and throat, and a...

Problems solved by technology

[0006] 3 The medicine liquid is not evenly dispersed when spraying

[0007] 4. The container for the liquid medicine is a glass vessel without scales, so the dosage cannot be calculated, and the liquid medicine at the bottom of the medicine bottle cannot be completely sucked out for use, resulting in waste; and the glass vessel is fragile

[0008] 5 Do not inhale oxygen while spraying the liquid medicine

[0009] 6 The extruded airbag is easy to age and thus reduces the effect of the spray

[0010] 7 Two people are required to operate during the operation, otherwise the exposure should be stopped, and the patient can only open his mouth to spray the liquid medicine, so that satisfactory local anesthesia cannot be performed
