Technical Field

The invention relates to the technical field of medical instruments, in particular to the field of transfer vehicles, and particularly relates to an operation transfer vehicle for transporting patients with infectious diseases and a using method thereof.

Background

At present, the common transmission routes of infectious diseases are airborne transmission such as droplet transmission and close-range contact transmission. The exhaled air of some infectious disease patients is harmful and is an important infectious disease source. In the treatment or nursing process, doctors, nurses and nurses need to wear protective clothing and bring a mask to contact.

However, during the time that an infected patient needs to leave the ward for transport, the patient is completely exposed to the air. The respiratory droplets of the completely exposed patients contain a large amount of pathogenic bacteria and viruses, and medical staff often need to contact the patients with infectious diseases at close distance or even zero distance, so that the infection probability of the medical staff is high, and the life health of the medical staff is greatly threatened. At present, some transfer vehicles with an isolation function in the prior art have the problem of poor sealing performance, and the existing transfer vehicle with the isolation function has poor sealing performance of an operation opening, so that viruses are easily spread outwards when operating a patient in a transfer process, and the flexibility of medical operation of medical staff on the patient in the transfer process is limited.

And the current long-distance transportation of infectious patients needs to use a special negative pressure ambulance, but the current negative pressure ambulance has higher cost and smaller use amount, and the quantity of the negative pressure ambulance can not meet the use requirement when facing the large-scale epidemic situation of infectious diseases.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the operation transfer trolley for transporting the patients with infectious diseases and the using method thereof, wherein the operation transfer trolley has good sealing performance, is safe and reliable and is convenient to operate.

The invention is realized by the following technical scheme, and provides an operation transfer trolley for transporting patients with infectious diseases, which comprises a trolley plate, a transparent cover reversely buckled on the upper end surface of the trolley plate and a plurality of travelling wheels arranged below the trolley plate, wherein one side of the transparent cover is hinged with the trolley plate, the upper end surface of the trolley plate is provided with a boss matched with the inner ring of the transparent cover, the side surface of the boss is fixedly connected with a circle of air bag, the air bag is positioned between the boss and the transparent cover, and an air suction pump and an air outlet pump which are communicated with the air bag are arranged below the trolley plate; open on the translucent cover and have a plurality of operation mouth, be equipped with the telescopic tube that is located the translucent cover inside on the operation mouth, telescopic tube's one end and translucent cover sealing connection, the inner circle of the telescopic tube other end seals the rigid coupling respectively along upper and lower direction and has elasticity sealing bag and elastic support strip, is equipped with non-Newton fluid in the elasticity sealing bag, the sealed rigid coupling in both ends of elasticity sealing bag and elastic support strip handing-over department.

In the scheme, the opening and closing of the transparent cover are realized by hinging one side of the transparent cover with the vehicle plate, gas is injected into the air bag through the gas outlet pump, the boss and the transparent cover are sealed through the expansion of the air bag, the air inside the transparent cover can be prevented from flowing out, so that the isolation effect is achieved, when the transparent cover needs to be opened, the gas in the air bag is pumped out through the air suction pump, the air bag is separated from the transparent cover, the transparent cover is opened through rotating the transparent cover along the hinged shaft, and a patient leaves the transfer vehicle.

Through elasticity sealing bag and the elastic support strip that sets up in this scheme, operating personnel struts between elasticity sealing bag and the elastic support strip through the hand, when operating in deepening the translucent cover with the hand, the elasticity through elasticity sealing bag and elastic support strip presss from both sides tight operating personnel wrist, and it is sealed with the wrist laminating to make elasticity sealing bag through the fluidic gravity of non-Newton, after the operation is accomplished, operating personnel takes the hand out, only need to change the outside gloves of barrier gown can, the demand to barrier gown has reduced protective articles's consumption in the reduction operation greatly, cross infection's risk has been reduced. After the operation is finished, the elastic sealing bag is attached and sealed with the elastic supporting strip through the gravity of the non-Newtonian fluid in the elastic sealing bag, and due to the characteristics of the non-Newtonian fluid, the non-Newtonian fluid cannot swing randomly when the transfer trolley shakes, so that the effective sealing between the elastic sealing bag and the elastic supporting strip can be ensured. The sealed rigid coupling in both ends of elasticity sealing bag and elastic support bar handing-over department to sealed effect between elasticity sealing bag and the elastic support bar has been strengthened, separates operating personnel's arm and cuff and patient through telescopic tube in this scheme, and operating personnel stretches into telescopic tube with the arm, and stretches out the hand from telescopic tube keeps away from the one end of translucent cover, and telescopic tube can stretch out and draw back the bending, thereby the operating personnel arm of being convenient for removes.

As optimization, one end of the telescopic sleeve, which is far away from the transparent cover, is fixedly connected with an annular hard sleeve head in a sealing manner, and the elastic sealing bag and the elastic supporting strip are fixedly connected with the inner ring of the hard sleeve head in a sealing manner. The stereoplasm sleeve pipe head that sets up in this scheme is used for fixed elasticity sealing bag and elastic support strip.

The inner ring of the fixed end of the telescopic sleeve and the transparent cover is larger than that of the other end. In the scheme, the inner ring of the fixedly connected end of the telescopic sleeve and the transparent cover is larger than the inner ring of the other end of the telescopic sleeve, so that the moving range of the arm in the operation process can be enlarged.

As optimization, the lower end face of the vehicle plate is provided with a folding supporting leg, the traveling wheels are arranged at the lower end of the folding supporting leg, and the lower end face of the vehicle plate is also provided with a plurality of supporting wheels.
