Description

Spraying disinfection transmits cabinet

This utility model relate to a kind of by the contaminated area to the clear area, especially in clean laboratory animal raising room and Animal Lab., transmit the device of sterilizing objects.

In clean laboratory animal raising room and Animal Lab., transmit sterilizing objects by the contaminated area to the clear area has three kinds of devices in the past: two door leafs pulse vacuum steam sterilization cabinet is used for high temperature resistant, as to be afraid of wet article sterilization and transmission; The disinfectant solution aqueduct is used to be afraid of high temperature, is not afraid of the sterilization and the transmission of wet article; The disinfection by ultraviolet light pass-through box is used to be afraid of that high temperature is afraid of the sterilization and the transmission of the article that wet again.Because two door leaf pulse vacuum steam sterilization cabinets and disinfectant solution aqueduct weight are all at the 1.5-2.5 ton, placed side by side on the ground in same room, general floor can't bear their weight, so in the reconstruction process of clean laboratory animal raising room and Animal Lab., can only establish article transmission channels of disinfection by ultraviolet light pass-through box when running into floor load-bearing problem.And ultraviolet radiation less than the entrained microorganism of body surface with after transmitting article and entering cleaning level district, can cause the clear area to pollute, influence the health and the zooperal result of clean laboratory animal.

The purpose of this utility model provides a kind of in clean laboratory animal raising room and Animal Lab., transmits the device of sterilizing objects by the contaminated area to the clear area in the mode of spraying disinfection, and it can carry out disinfection to the surface of transmitting article effectively.

The purpose of this utility model is achieved in that through reaching lateral three conical nozzles above the cabinet, with disinfectant with atomized spray to the transmission article that are enclosed in the cabinet, after the sealing sterilization, with 100 grades of filtered airs disinfectant abnormal smells from the patient in the cabinet is entered the contaminated area again, thereby import article into clear area with aseptic condition.

The utility model has the advantages that: (1) can be sprayed onto disinfectant surface and the cabinet inner surface that transmits article in the cabinet by three conical shaped spray mouths, and sterilization thoroughly; (2) carry out 100 grades of filtrations by gas, can prevent effectively that microorganism is to the recontaminate of sterilizing objects in the cabinet in the air air inlet and gas outlet; (3) lightweight material manufacturing such as available lucite, in light weight, needn't consider floor load-bearing problem during installation; (4) only adorn two Door lock with linakage locking bar, three nozzles and two blow vents on cabinet, structure is very simple, and is safe and convenient to use.

Fig. 1 is the axonometric chart that transmits cabinet according to the spraying disinfection that the utility model proposes.

Fig. 2 is the vertical section sketch map of conical shaped spray mouth.

Describe the details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with Fig. 1 and Fig. 2.

There are chain external door (1) and inside door (7) in the cabinet two ends of this device, a conical nozzle (3) has respectively been installed with vertical direction in above the cabinet and two side faces center, is equipped with respectively on cabinet both sides, diagonal position with air inlet (8) and gas outlet (4), the nearly inside door of cabinet (7) 1/3rd positions of 100 grades of filters (2) sealing strip (5) and sealing strip clip (6) are housed.

At first sealing strip (5) is fixed on the wall during installation, clear area and contaminated area are separated.When transmitting article, under inside door (7) closing state, open external door (1), seal external door (1) after putting into article, spray disinfectant through three conical shaped spray mouths (3) to different directions, the angle of conical shaped spray mouth (3) is 30 °--in the time of 45 °, the fog-spray nozzle of aerosol apparatus (not marking among the figure) rotates flexibly.After the airtight sterilization, send into the air of cleaning with mini fan (not marking among the figure) through air inlet (8) and 100 grades of filters (2) in cabinet, (4) are discharged to the contaminated area through 100 grades of filters (2) from the gas outlet with disinfectant abnormal smells from the patient in the cabinet by air pressure.Under external door (1) closing state, open inside door (7), article promptly import the clear area into aseptic condition.
