For guaranteeing the accuracy of experimental data, laboratory animal need to be raised in aseptic environment.At present, the feeding manner of existing laboratory animal be by animal feeding in thering is the ventilating cage box of life window, and then numerous ventilating cage boxes are placed in to aseptic raising indoor feeding in order.
Yet the upper cover of above-mentioned ventilating cage is all provided with life window, be only suitable for raising healthy laboratory animal.When raising infected laboratory animal, germ is easily diffused in aseptic receptacle from life window, infects other laboratory animal or experimenter, is difficult for raising infected laboratory animal.
Utility model content
In view of this, a technical problem to be solved in the utility model is to provide a kind of upper cover of negative pressure independent ventilating cage, and upper cover is airtight, guarantees that in independent ventilating cage be negative pressure state, is applicable to raising infected laboratory animal.
For realizing above-mentioned technique effect, the utility model provides a kind of upper cover of negative pressure independent ventilating cage, its surface has the installation portion that protrudes upper cap surface, the side of described installation portion is provided with air inlet and exhaust outlet, and the edge of described upper cover is provided with rib vertical with upper cover and that bend to upper cover below.
Preferably, the installation portion of described upper cap surface is also provided with the water bottle standing groove being recessed to ventilating cage casing, and the bottom of described standing groove arranges inlet opening.
Preferably, in described air inlet and exhaust outlet, be separately installed with valve.
Preferably, described valve comprises: the joint with air inlet and gas outlet; The venting cavity with air inlet and gas outlet, the air inlet of venting cavity docks with the gas outlet of joint; The base that surface is relative with the gas outlet of venting cavity; Gripper shoe, connects base and venting cavity.
Preferably, the gas outlet that described gripper shoe one end connects venting cavity and separates described venting cavity, the other end of described gripper shoe connects and separates base.
The utility model provides a kind of upper cover of negative pressure independent ventilating cage, its surface has the installation portion that protrudes upper cap surface, the side of described installation portion is provided with air inlet and exhaust outlet, and the edge of described upper cover is provided with rib vertical with upper cover and that bend to upper cover below.The air inlet of upper cover connects ajutage, the gas outlet of upper cover connects blast pipe, the rib of upper cover fastens the side of ventilating cage casing, air enters in cage box through ajutage and air inlet, in cage box, air arrives appointed place through gas outlet and emission by exhaust pipe, complete negative pressure in cage box, and in cage box, air is difficult for leaking, place outside cage box just can not be contaminated, thereby reduced the chance that other animal or human persons are infected in a large number.
