Description

Ventilation equipment is used in infectious department ward

Technical Field

The utility model relates to the field of medical equipment and equipment, concretely relates to ventilation equipment is used in infectious department ward.

Background

In the infectious department, patients in the infectious department are more common in viral hepatitis, liver cancer, mumps, cirrhosis, lung infection, pulmonary tuberculosis, pleuritis, upper gastrointestinal hemorrhage and the like, and particularly, the patients with pulmonary tuberculosis, epidemic hemorrhagic fever and severe hepatitis are more patients, and the prevention of cross infection is an important part of wards in the infectious department, so that ventilation and air exchange of wards in the infectious department are particularly important.

The main purpose of ventilating the ward is to exhaust the waste air in the ward and ensure the necessary fresh air volume in the ward. Ventilation in traditional ward all only opens the window in ward usually and ventilates, and ventilation effect is unsatisfactory to there are a large amount of bacterium and dust in the air, under normal conditions, because the human body has immunity, so can not infected by the bacterium, however the patient in infectious department ward is infected by the bacterium very easily, consequently, need carry out disinfection and isolation to the air that gets into the ward to guarantee that the patient is not infected. The prior art also has the problem that ventilation and air exchange of a ward are realized through a ventilation fan, but the ventilation quantity cannot be adjusted by adopting the structure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a ventilation equipment is used in infectious department ward can adjust the size of air volume to patient's actual need in the adaptation infectious department ward.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a ventilation equipment is used in infectious department ward, including air inlet unit and exhaust apparatus, air inlet unit includes intake pipe and air inlet fan, exhaust apparatus includes blast pipe and air discharge fan, all be equipped with filtration piece in intake pipe and the blast pipe, and all be equipped with flow control mechanism on intake pipe and the blast pipe, flow control mechanism includes the spherical casing with blast pipe or intake pipe intercommunication, be equipped with the adjusting ball in the spherical casing, the outer wall of adjusting ball pastes with the inner wall of spherical casing mutually, set up the radial passageway that can communicate with intake pipe or blast pipe in the adjusting ball, still be fixed with the regulation passageway with the inside intercommunication of spherical casing on the spherical casing, the regulation passageway internalization is provided with the transmission shaft fixed with the adjusting ball.

The principle and the beneficial effect of the scheme are that:

the air inlet device is used for introducing outdoor clean air into a room, and the exhaust device is used for introducing indoor dirty air to the outside, so that ventilation and air exchange of a ward are realized. The air inlet device introduces outdoor air into the air inlet pipe through the air inlet fan and then enters the ward, and the air exhaust device introduces air in the ward into the air exhaust pipe through the air exhaust fan and then exhausts the air to the outside. The air filter can purify air entering the exhaust pipe and the air inlet pipe, can remove bacteria and dust in the air, and ensures that the air entering a ward and the air discharged outdoors from the ward are relatively clean.

The flow regulating mechanism can regulate the air flow in the air inlet pipe and the air outlet pipe, namely regulate the ventilation quantity of a ward so as to adapt to the actual needs of patients in the ward of an infectious department. The principle of the flow regulating mechanism for regulating the ventilation quantity is as follows: when the radial channel on the adjusting ball is aligned with the air inlet pipe or the exhaust pipe, the air in the air inlet pipe or the exhaust pipe continuously flows forwards after passing through the radial channel on the adjusting ball, the aligned area of the radial channel and the air inlet pipe or the exhaust pipe can be changed through the rotation of the adjusting ball, namely, the air quantity entering the radial channel is adjusted, and therefore the flow rate of the air inlet pipe and the exhaust pipe is adjusted.

Further, the air inlet device is positioned above the exhaust device. Outdoor clean air is introduced into the room through the air inlet device, and gradually descends from the position above the room, so that the air exchange is performed indoors, and the effect is better.

Further, exhaust apparatus and air inlet unit all include the shell, and the transmission shaft even has transmission bevel gear, and transmission bevel gear meshing has regulation bevel gear, and the coaxial regulating spindle that is fixed with of regulation bevel gear, regulating spindle rotate to be connected on the shell. Through the meshing of transmission bevel gear and regulation bevel gear, adopt the rotation of rotatory mode of adjusting the axle to drive the rotation of transmission shaft, and then drive the rotation of adjusting the ball, realize the regulation of flow.

Furthermore, a handle is fixed at the end part of the adjusting shaft. When the adjusting shaft is rotated, the adjusting shaft can be rotated by holding the handle by hands, so that the operation is more convenient.

Furthermore, the handle is provided with anti-skid lines. The antiskid lines can avoid the phenomenon that the hands skid when holding the handle.

Furthermore, a dial is arranged on the shell, and a pointer is fixed on the adjusting shaft. When the adjusting shaft is rotated, the rotating angle of the adjusting shaft can be accurately judged through the position of the pointer on the adjusting shaft on the dial, namely the flow regulation size of the exhaust pipe or the air inlet pipe is judged.

Furthermore, both ends of the exhaust pipe and the air inlet pipe are provided with ventilation dust screens. The ventilation dust screen can carry out preliminary dust removal to the air that gets into blast pipe and intake pipe, avoids in a large amount of dusts get into blast pipe and intake pipe.

Further, the air filter is activated carbon. The activated carbon has good adsorption effect and low cost.
