Description

Mouth and nose negative pressure air extractor for preventing toxic overflow special for new coronavirus tracheal intubation

Technical Field

The utility model relates to the field of medical equipment, particularly, relate to an excessive oronasal negative pressure air exhaust device of special anti-virus of new coronavirus trachea cannula.

Background

In some cases, the patients with severe illness need respiratory support for tracheal intubation due to respiratory failure, and the patients with new coronavirus infection who need general anesthesia surgery need tracheal intubation.

As is well known, endotracheal intubation is one of the most intensive clinical procedures in contact with the airway of a patient, and is prone to cause such things as secretion splash, spray, aerosol diffusion, etc., and is susceptible to infection by the anesthesiologist performing the procedure. The bigger problem is that a large number of patients wait for operation treatment at present, and the existing situation can not adopt the upgrade protection to treat each patient, but the operators of the common protection have great risks in the face of the patients in the latent period. Therefore, how to protect the tracheal intubation period is a real problem to be faced by the anesthesiologist every day.

In the operation process of carrying out tracheal intubation on a patient, an anaesthetist needs to close the patient in a very close distance, open the oral cavity, open the glottis and find an airway, air containing high-concentration viruses can be swept out, the anaesthetist needs to finish operation as soon as possible to ventilate the patient, and the anaesthetist is particularly examined in case of difficult tracheal intubation with poor intubation conditions. At ordinary times, a tracheal intubation and an anaesthetist generally have about 3-5 minutes of operation time, but the tracheal intubation is difficult, even at ordinary times, the difficult problem is also brought to the anaesthetist, and even at present, new coronary pneumonia is abused at frequent time. The longer the operation time, the more adverse to the patient, and for the anaesthetist, the operation time is preferably not more than 90 seconds, otherwise the probability of infecting new coronary pneumonia is greatly increased, and the anaesthetist is greatly challenged in the aspect of technical or psychological bearing capacity when being soaked in the air with high-concentration virus. And aerosol dissemination is currently suspected to be a possible way of causing transmission of new coronavirus. Researches find that the patient simulator can simulate cough in a horizontal position, and the distance of the sagittal plane of the patient simulator can reach about 86 cm. The distance of dissemination during positive pressure ventilation of the face mask can reach about 26.7cm, so the positive pressure ventilation period before tracheal intubation also has serious risks.

Aiming at the situation, the temporary countermeasure of medical staff for severe patients during tracheal intubation at present is to isolate the heads of the patients by adopting a barrier film, namely, the heads of the patients are worn with transparent plastic hoods and the hoods are provided with holes for positive pressure ventilation of masks and tracheal intubation. The measure has the advantages of low cost, certain prevention of dispersion of spray and aerosol, avoidance of pollution to medical instruments and the like. However, this temporary method also has the following disadvantages:

1. the adhesive plaster between the film and the consumable has poor adhesion reliability, and once the adhesive plaster falls off, the sealing is easy to cause untight and the function is lost.

2. The air permeability is not available, the patient is easy to feel stuffy and the body surface temperature is increased under the closed state, and the patient is very dangerous for serious patients.

3. The hood makes the doctor can't stretch into to patient oral area in as the protective screen finger when carrying out trachea cannula, has increased trachea cannula's the operation degree of difficulty, and extension operating time will lead to the patient to appear holding out the breath the circumstances such as, has increased patient's risk.

4. Although the hood is made of transparent plastic materials, the hood has the condition of reflecting light under the irradiation of surgical lamplight, the reflection of the hood is very unfavorable for operating doctors to observe the insertion condition of the tracheal cannula, the operation difficulty is greatly increased, and the risk of failure of the tracheal cannula is increased.
