Description

Anti-aerosol operation box

Technical Field

The utility model relates to an utensil, more specifically the prevent aerosol control box that says so is assisted in the inspection.

Background

Safety protection in medical examination professional laboratories involves a number of aspects, of which the generation and protection of laboratory aerosols is an important part. Many routine operations can generate aerosols and circulate air that can cause laboratory contamination and infection of laboratory personnel. In the laboratory, aerosol infection control must be achieved to avoid aerosol generation, prevent aerosol diffusion, and provide safety protection for laboratory personnel. Since some experimental operations inevitably produce aerosol, it is important to prevent diffusion. At present, a plurality of measures can effectively prevent the aerosol from diffusing, such as 'enclosure operation', 'effective interception', 'directional airflow', 'air disinfection' and the like, and the comprehensive utilization of the protection measures can obtain good practical effects. The enclosure operation is to limit the infectious substances in a space as small as possible for operation, so that the infectious substances are not in direct contact with human bodies and are isolated from open air, and the enclosure operation with a proper size can ensure safety, economy and reasonableness.

With the development of modern and intelligent scientific technology, hospitals above the market level are provided with various fully automatic inspection instruments, samples are processed from front treatment to abandonment in closed instruments, and the operation of aerosol generation is instrumented and automated, so that potential biological safety hazards in laboratories are greatly reduced. However, most small laboratories and small towns hospitals have no condition to purchase the fully automatic instruments due to small sample amount and low capital, and all tests are semi-automatically or even fully manually operated, so that the risk of aerosol pollution in the laboratories and infection of laboratory staff is increased.

Disclosure of Invention

"tube decapping" is a routine operation involving each laboratory, and is also an operation for generating aerosols. The current full-automatic cap pulling machine sold in the market cannot be popularized and applied in small laboratories and village and town hospitals due to the factors of higher price, certain occupied space, suitability for large-batch specimen operation and the like. The harm of aerosol infection to laboratory and rural hospital laboratory personnel with inadequate protection measures and weak protection consciousness causes high attention. In view of the current situation, the operation of pulling the cover of the test tube is improved and designed, and the environment operation principle is utilized, so that the environment with proper biological protection is set, the purpose of safety and economy is achieved, and the operation is convenient to popularize and apply in laboratories and hospitals with insufficient economic conditions.

The anti-aerosol operation box mainly comprises a box body, a box door, an exhaust pipe, operation gloves, a fixing ring, a sealing ring, a ventilation fan and a disinfection device.

One side of the box body is provided with a box door, and the box body and the box door are made of transparent materials.

Two side surfaces of the box body are respectively provided with a mounting hole, and the operating glove is mounted on the mounting holes by a fixing ring; in order to ensure the whole sealing performance, the operation gloves are lengthened or overlong colloid gloves, a sealing ring is arranged at the joint of the box body and the box door, and after the box door is closed, the ventilation fan is removed, so that the anti-aerosol operation box is isolated from the outside to form a closed environment.

The top surface of the box body is provided with an exhaust pipe, and the top end of the exhaust pipe is provided with a ventilation fan.

The sterilizing device adopts an ultraviolet lamp and is arranged in the box body.

Detailed Description

In small medical units such as clinics and health hospitals, the full-automatic cap pulling machine cannot be purchased to perform the anti-aerosol work as a large medical unit due to the limitation of conditions and funds. The number of these units to be treated is very small, such as "tube decapping" which is only a few or two, thirty, one or two, three at a time, and generally no more than five. The number is small, but there is also a risk that infection will be prevented. According to specific practical conditions, only manual operation can be carried out to carry out the 'test tube cap removal', but the working process is carried out in a closed environment. The anti-aerosol operation box provides a closed operation environment, prevents the dispersion of aerosol from causing the infection of operating personnel, and can meet the requirements of enclosure operation, effective interception, directional airflow and air disinfection.

The anti-aerosol operation box is placed on an operation table to work, the number of test tubes placed in each time is small, and the anti-aerosol operation box is generally placed on a test tube rack. The size of the box is not too large, which may have a certain effect on the operation. The box body can be rectangular with the length of 50-60 CM, the width of 50-60 CM and the height of 60-70 CM or in other shapes, so long as the operation is convenient.

One side of the box body is provided with a box door, and the box door can be rectangular, circular or other shapes, so long as the test tube rack can be conveniently put in and taken out from the box door. For observation and operation, the box body and the box door are made of transparent materials, and if the lighting condition is increased, a lighting device can be additionally arranged in the box body.

In order to facilitate the operation of pulling the cover by both hands, two side surfaces of the box body are respectively provided with a mounting hole, operation gloves are arranged in the mounting holes, and the operation gloves are fixed in the mounting holes by a fixing ring. The operation gloves are made of airtight, lengthened or overlong rubber gloves or other airtight gloves, and if no proper gloves are available, plastic bags can be used instead. The length of the fixed operation gloves is half longer than that of the box body, and the operation in the box can be conveniently finished. After the operation glove is installed in the installation hole, the operation glove is in a sealed state. During operation, both hands of an operator enter the box body through the operating gloves from the mounting holes on the two sides of the box body, and related operation can be performed. The operating gloves are damaged due to long-term use, the sealing performance is reduced, and the operating gloves are reinstalled after the fixing ring is taken down. The arrangement is practical and convenient. The box still needs as other operations like this, and the box is longer, can set up the mounting hole on the same face of box.

The anti-aerosol operation box is required to be a closed environment, and the air leakage part at the joint of the box body and the box door is prevented, so that the sealing requirement cannot be met. A sealing ring is arranged at the joint of the box body and the box door, and after the box door is closed, the space in the anti-aerosol operation box is isolated from the outside to form a closed environment.

The gas in the anti-aerosol operation box still needs to be discharged outside the box (air exchange inside and outside the box), an installation exhaust pipe is arranged on the top surface of the box, a ventilation fan is arranged at the top end of the exhaust pipe, the gas in the conditions is discharged outside the box from the exhaust pipe through the ventilation fan, a filtering device is arranged at the front end or the rear end of the ventilation fan for ensuring safety, and the gas which is extracted is discharged outdoors after being filtered by the filtering device.

The box is convenient for the air disinfection of incasement, sets up degassing unit in the box, and degassing unit adopts ultraviolet lamp usually, installs in box top an angle department, can shine whole box inside.

The anti-aerosol operation box is safe, economical and simple to manufacture, and can be widely used in small medical units such as clinics, health centers and the like.
