Description

Anti-splashing isolation hood

Technical Field

The invention relates to the technical field of medical instruments, in particular to an anti-splashing isolation hood.

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.

Disclosure of Invention

In order to overcome the defects, the invention provides an anti-splashing isolation hood.

The technical scheme adopted by the invention for solving the technical problems is as follows:

an anti-splash isolation hood comprises a support, a transparent window and an isolation hood towel, wherein the support comprises support legs, and is characterized in that the transparent window is provided with an operation hole, a sealing membrane is arranged in the operation hole, and the sealing membrane is provided with a notch to enable the sealing membrane to form an air-blocking valve; the landing leg of support is retractable landing leg, and the top of landing leg is articulated bottom with transparent window and is made the landing leg can turn over.

Furthermore, the skirt edge of the isolation cover kerchief is provided with an adhesive tape which is used for being attached to the periphery of the head of the patient; the transparent window is also provided with a breather valve.

Furthermore, keep apart the hood still includes the layering, transparent window border is equipped with annular layering mounting groove, and the isolation cover piece passes through the layering crimping in the layering mounting groove.

Furthermore, the cut of the sealing membrane is in a cross shape or a meter shape.

Furthermore, the sealing membrane is in an inverted cone shape, and the notches are radially distributed from the bottom end of the sealing membrane along the inclined surface of the sealing membrane.

Further, the adhesive tape is annularly arranged along the skirt edge of the isolation cover kerchief.

Furthermore, the periphery of the supporting leg is sleeved with a locking nut, and the locking nut is used for locking and fixing the telescopic position of the supporting leg.

Furthermore, the adhesive tape adopts double-sided adhesive tape.

Further, the operation hole comprises more than one.

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

The invention has the beneficial effects that:

firstly, an operation hole is arranged on a transparent window, air is isolated through a sealing membrane forming an air-blocking valve, and surgical instruments can be inserted into the isolation hood from an incision, so that the infection risk caused by lifting an isolation hood towel is avoided, and the operation of medical personnel is facilitated; 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.

Secondly, the skirt edge of the isolation cover towel is bonded with the periphery of the head of the patient by the adhesive tape, so that the sealing effect is achieved, the aerosol is prevented from spreading, and the infection risk of medical staff is reduced; the sealing effect can be improved by arranging the adhesive tape along the skirt edge in a ring shape, and aerosol is completely isolated; the double faced adhesive tape is convenient for the operation of medical personnel, and the use efficiency is improved; when the isolation cover kerchief is completely sealed with the body of the patient, the normal breathing of the patient can be ensured through the breathing valve.

The distance between the transparent window and the patient can be adjusted through the telescopic supporting legs, and when the distance is in a proper position, the inner side of the transparent window does not generate water vapor accumulation any more, so that the visual field of medical personnel is ensured; in addition, the supporting legs at the front side and the rear side of the transparent window can be adjusted to different heights, so that the plane of the transparent window is changed, the transparent window is inclined, the visual field of medical personnel is changed, and the operation is facilitated; after turning over the landing leg, can reduce the volume of this isolation hood, be convenient for accomodate and transport, simultaneously, can turn over the landing leg of rolling over and can be after the operation, together with keep apart the cover piece and draw together, prevent the propagation of operation back aerosol.

And fourthly, a pressing strip mounting groove is formed in the transparent window, when the transparent window and the isolation cover towel are assembled, the isolation cover towel is directly pressed in the pressing strip mounting groove through the pressing strip, the assembly is convenient and rapid, and the production and manufacturing efficiency is greatly improved.
