Negative pressure device for preventing novel coronavirus from splashing

Abstract

The invention relates to the technical field of medical protection device, in particular to a negative pressure device for preventing novel coronavirus from splashing, which is characterized in that ashell is a hollow rectangular box without a bottom surface, the rear surface of the shell is used as a tail side surface, and a through hole is formed in the tail side surface to be used as a negative pressure suction connecting hole; one end of the connecting pipe is connected with the negative pressure suction connecting hole, the other end of the connecting pipe is connected with a filter, thefilter is connected with a negative pressure device, and the negative pressure device is connected with a virus-killing device. The beneficial effect of the invention is to transfer the protection object from the operator to the patient, cut off the transmission path by controlling the source of infection, reduce the risk of infection, so as to protect the medical staff. Aerosol formed by splashed secreta and gas with viruses exhaled by a patient are sucked away and inactivated in time, which not only reduces the probability of virus diffusion and infection, but also reduces the fear and physical discomfort of medical staff, so that the accuracy of the operations is improved, and therefore the treatment effect of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical protective equipment, in particular to a negative pressure device for preventing the splashing of the new coronavirus. Background technique [0002] When the condition of patients with new coronary pneumonia progresses to critical illness, it is necessary to promptly suck sputum to keep the airway open, non-invasive ventilator positive pressure ventilation therapy, endotracheal intubation and invasive ventilator treatment, after the condition improves, the tracheal tube needs to be removed, and patients with new coronary pneumonia infection need to perform surgery Endotracheal intubation and general anesthesia are required. [0003] As we all know, these operations are one of the clinical operations that are most closely in contact with the patient's airway, and are prone to secretions or blood splashes, droplets, and aerosol diffusion. Due to factors such as sweating, long time, weak protection ...

AI Technical Summary

Problems solved by technology

[0007] 1. The bonding reliability of the adhesive tape between the film and the consumables is poor. Once the adhesive tape falls off, it is easy to cause lax sealing and lose its effect

[0008] 2. In the airtight state, it is easy to cause the patient to feel stuffy and the temperature of the body surface rises, which is very dangerous for the critically ill patient

[0009] 3. The hood acts 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 intubation operation, and prolonging the operation time will cause the patient to suffocate and increase the risk of the patient

[0010] 4. Although the hood is made of transparent plastic, it reflects light under the illumination of the operating light, which affects the doctor's observation of the insertion of the intubation, greatly increases the difficulty of operation, and increases the risk of tracheal intubation failure
