Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a prevent isolating helmet that splashes.
Background
When a medical worker performs an invasive operation for diagnosing and treating lung and stomach diseases or performs operations such as sputum suction and off-line tests of a breathing machine on a patient through endoscopy (such as bronchoscopy and gastroscope), the medical worker needs to contact the patient at a short distance, and the medical worker can take a protective measure in order to prevent iatrogenic infections (such as bacteria and viruses).
During the period of epidemic outbreak of infectious diseases, when an operator (patient) is known to be an infectious disease patient, medical staff can wear medical protective isolation articles, such as medical protective clothing and headgear, but the medical protective isolation articles have the defects of influencing the visual field of doctors and the accurate operation of operations, and the comfort level of the operator is poor; and all operators need to wear the protective headgear, and the resource consumption is large.
In a non-epidemic situation, because whether the operator is an infectious disease patient is unknown, the medical staff generally only wears a conventional operating coat, and the patient sneezes, coughs or vomits due to stimulation of invasive surgical instruments in endoscopic operation, so that spray, sputum, gastric contents or blood are splashed onto the face or body of the medical staff, and the medical staff is easily infected.
At present, there is an anti-splash isolation towel for patients during operation, the patients lie on an operating table and then cover the face of the patients, the patients are observed through a transparent window, and medical staff operate surgical instruments through oversleeves.
However, this approach has the following drawbacks:
firstly, because the isolation piece of cloth directly covers patient's face, there is the space between isolation piece of cloth edge and the patient's health, there is not the way to isolate aerosol propagation path, still has great infection risk to medical personnel.
Secondly, due to the obstruction of the isolation towel, the operation space is limited, which is inconvenient for the operation of the operator. For example, invasive procedures: diagnosis and treatment through bronchoscope, trachea cannula, diagnosis and treatment through gastroscope, arteriovenous incision, tracheotomy, percutaneous puncture, fistulization and other similar operations, non-invasive operation: oral tracheal intubation, aerosol inhalation, ventilator therapy offline test, high flow oxygen inhalation, sputum aspiration and the like are required to prevent secretion of a patient from polluting related operations of an operator. The isolation towel is required to be lifted up firstly, surgical instruments are plugged into the lower part of the isolation towel, then the isolation towel is closed, and then the operation can be carried out through the oversleeve. On the one hand, the method inevitably increases the risk of infection, and on the other hand, the operation flow becomes complicated, and the operation efficiency is influenced.
And thirdly, the patient is easy to form water vapor on the transparent window when breathing, and the water vapor is gathered at the inner side of the transparent window and cannot be erased, so that the visual field of the medical care personnel is influenced.
And fourthly, the isolation cover kerchief and the transparent window are connected by adopting a pressing process, the process is complicated, the efficiency is low, and the production and manufacturing efficiency of the isolation cover kerchief and the transparent window can not meet the requirements far during epidemic outbreak.
