Description

Anti-splashing isolation hood convenient for operation

Technical Field

The utility model relates to the technical field of medical equipment, specifically a make things convenient for operation's isolation hood that prevents splashing.

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 ventilator off-line tests on a patient through endoscopy (such as bronchoscopes and gastroscopes), 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 during endoscope operation in the 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. Although this form reduces the risk of infection exposure during surgery and operation to some extent, the isolation towel has limited space and is inconvenient for the surgeon to operate. 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.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anti-splashing isolation hood convenient for operation, which has large operation space, can place the instruments needed by operation in the isolation hood in advance, does not need to open an isolation hood towel in the operation process, reduces the infection risk, simplifies the operation flow and shortens the operation time; the isolation hood is light and firm and has strong supporting force, so that the isolation hood can be operated by a single person; and only one person of the patient is needed to wear the isolation hood, so that the consumption of personnel and materials is effectively reduced.

The utility model provides a technical scheme that its technical problem adopted is:

an anti-splash isolation hood convenient for operation comprises a bracket, a transparent window and an isolation hood kerchief, wherein the transparent window is provided with an operation hole, and a choke valve is arranged in the operation hole; the choke valve comprises a sealing diaphragm, and the sealing diaphragm is provided with an arc-shaped notch which is arranged in a downward inclined mode.

Further, the arc-shaped notches are downwards inclined at an angle of 45 degrees.

Further, the arc-shaped notch is preferably arc-shaped.

Further, the operation hole comprises more than one.

Further, the size of the operation hole is more than one.

The utility model has the advantages that the transparent window is provided with the operation hole, the air is isolated by the sealing membrane forming the air-blocking valve, the surgical instruments can be inserted into the isolation hood from the incision, thereby avoiding the infection risk caused by lifting the isolation hood towel and facilitating the operation of medical personnel; the operation holes with different sizes are arranged, so that the operation hole can meet the requirements of various surgical instruments and is flexible to use.
