Problems solved by technology

[0006] 1. The bonding reliability of the tape between the film and the consumables is poor. Once the tape falls off, it is easy to cause the seal to be loose and lose its effect
[0007] 2. There is no air permeability, and it is easy for patients to have air tightness and elevated body surface temperature in a closed state, which is very dangerous for critically ill patients
[0008] 3. The hood serves as a barrier so that the doctor cannot extend his fingers into the inner area of ​​the patient's mouth during tracheal intubation, which increases the difficulty of tracheal intubation operation. Prolonging the operation time will cause the patient to hold his breath, etc., increasing the patient's risks of
[0009] 4. Although the hood is made of transparent plastic, it is reflective under the operating light. The reflection of the hood is very unfavorable for the operating doctor to observe the insertion of the tracheal tube, which greatly increases the difficulty of operation and increases the Risk of failed endotracheal intubation

Abstract

The invention relates to the field of medical instruments, in particular to a special oral-nasal negative-pressure air extractor capable of preventing viruses from overflowing and used for tracheal intubation of patients infected with new coronaviruses. The special oral-nasal negative-pressure air extractor comprises a frame body, an oral ventilation ring, an airway strip and a bandage, wherein the frame body is provided with a mouth vacancy at the mouth position of a patient, and is provided with a nose groove structure at the nose position of the patient; nose through holes are formed in thenose groove structure; a mouth ventilation ring is arranged at the part, located at the periphery of the mouth vacancy, of the outer side surface of the frame body; a hollow air passage in the mouthventilation ring is an annular air passage; a plurality of air holes are formed in the inner ring surface of the mouth ventilation ring; a nose air passage communicated with the nose through holes andthe annular air passage is formed in the mouth ventilation ring; the airway strip is arranged on the mouth ventilation ring and / or the frame body; two ports of the airway strip are communicated withthe annular air passage; an air receiving port is formed in the annular air passage; and two ends of the bandage are arranged on the frame body. According to the air extractor, air with viruses exhaled by the patient is sucked away through the air holes in the inner ring of the mouth ventilation ring and the nose air passage connected with the nose through holes.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel coronavirus tracheal intubation anti-virus overflow device for mouth and nose negative pressure suction. Background technique [0002] At present, the situation of the prevention and control of the novel coronavirus pneumonia epidemic is still severe. Among the hospitalized confirmed cases, some critically ill patients need respiratory support due to respiratory failure, and there are also patients with new coronavirus infection who need general anesthesia. Intubation. [0003] As we all know, endotracheal intubation is one of the clinical operations that have the closest contact with the patient's airway. It is prone to secretion splashing, droplets, aerosol diffusion, etc., and the anesthesiologist performing the operation is prone to infection. The bigger problem is that there are currently a large number of patients waiting for surgical treatment, and it is impossible ...
