Description
Technical field
This utility model belongs to sewage disposal apparatus, the sewage disposal apparatus of the most positive/negative pressure isolator, raises for DPF medical donor pig and tests with cause of disease.
Background technology
The high-level laboratory animal that animal experiment institute uses at present mainly has Sterilized isolator and animal barrier facility without specifying pathogen (Designed Pathogen free, DPF) medical donor swine rearing environment.Security impact evaluation test in researching and developing for animal pathogenic infection experiment research or animal vaccine, the feeding environment of the DPF laboratory animal used is Sterilized isolator.Breed experimental animals in Sterilized isolator or carry out animal experiment, feedstuff dust, animal wastes, urine and exuviae bits, it is all to use to be previously placed in the plastic sheeting of rolling in isolator and receive that feathers etc. are removed, when garbage reaches a certain amount of, first one plastic bag of Hatch Opening outer sheath is transmitted at dirt, and plastic bag mouth is sealed on dirt transmission Hatch Opening, sterilization hole spray disinfectant in the plastic bag sealed on dirt transmission Hatch Opening, after sterilization certain time, open dirt delivery bin hermatic door, in the incoming plastic bag of animal waste that will be wrapped up by plastic sheeting again, seal dirt delivery bin hermatic door, take off and fill with dirt plastic bag, laboratory is spread out of after sealing.But owing to the plastic sheeting that used is polluted by exogenous microbial during transport and storage unavoidably, and there is sterilization blind area before using, it is difficult to thoroughly sterilizing, this is to cause one of important sources of being polluted by inoculating microbe inside isolator.
During animal pathogenic experimental infection or animal vaccine security impact evaluation test, when clearing up the internal dirt of isolator, first one plastic bag of Hatch Opening outer sheath is transmitted at dirt, and plastic bag mouth is sealed on dirt transmission Hatch Opening, sterilization hole spray disinfectant in the plastic bag sealed on dirt transmission Hatch Opening, after sterilization certain time, open dirt delivery bin hermatic door, in the incoming plastic bag of animal waste that will be wrapped up by plastic sheeting again, seal dirt delivery bin hermatic door, it is again turned on the sterilization hole on dirt transmission Hatch Opening, inwardly spray disinfectant, after certain time, take off and fill with dirt plastic bag, laboratory is spread out of after sealing.In the process, not only elapsed time is longer, and, there is the halfway phenomenon of sterilization, it is most likely that cause the pathogenic infection microorganism used in infection experiment research to pollute the danger of external environment.
During it addition, use plastic sheeting to remove contamination, the garbage and the feedstuff dust that are difficult to produce animal in isolator are cleaned out every time, if drinking equipment occurs that drainage or water fountain are overturned by animal simultaneously, further increase the difficulty of cleaning.
Therefore, for DPF fowl, pig raises or DPF fowl, pig pathogen infection test positive and negative pressure isolator obtain a kind of exogenous pollution thing and can not enter, and what contaminating endogenous thing was unlikely to reveal sewage disposal apparatus just seems the most necessary.
Utility model content
The purpose of this utility model is to provide the sewage disposal apparatus of positive/negative pressure isolator, raises for DPF medical donor pig and tests with cause of disease, solves the shortcoming in background technology.
This utility model realizes by the following technical solutions:
nullThe sewage disposal apparatus of positive/negative pressure isolator，Raise for DPF medical donor pig and test with cause of disease，Including base plate、The dirty storehouse of storage、Oversleeve mouth、Fluid storage tank、Flow control valve、Spray orifice plate、Liquidometer、Upper end flow control valve、Lower end flow control valve、Force (forcing) pump、Shower and calabash pipe，The dirty bottom, storehouse of described storage is provided with base plate，Described base plate bottom is communicated with calabash pipe，Described calabash pipe top and bottom are pipe，Middle part is bulb tube，At the pipe of described calabash pipe upper end, upper end flow control valve is set，It is respectively provided with lower end flow control valve at the pipe of described calabash pipe lower end，Described storage is provided with oversleeve mouth in the middle part of dirty storehouse，The dirty top, storehouse of described storage is provided with spray orifice plate，Described fluid storage tank is arranged on the dirty top, storehouse of storage，It is provided with shower in described spray orifice plate，It is connected by pipeline between described shower and fluid storage tank，Force (forcing) pump and flow control valve it is disposed with between described fluid storage tank and shower.
In this utility model, described force (forcing) pump is frequency conversion pipeline force (forcing) pump.
In this utility model, described storage is provided with liquidometer in the middle part of dirty storehouse.
In this utility model, the dirty top, storehouse of described storage arranges the block number of spray orifice plate and is more than at least two pieces.
In this utility model, more than the twice of a diameter of top and bottom pipe diameter of the bulb tube in the middle part of described calabash pipe.
In this utility model, described fluid storage tank top is provided with overfall.
Beneficial effect: this utility model is by improving the structure of existing positive/negative pressure isolator, and the plastic sheeting replacing original positive/negative pressure isolator is removed contamination, can be prevented effectively from the plastic sheeting of use and remove contamination exogenous pollution that may be present；For experimental animal feeding during the medical former experimental study of donor swine diseases, on the one hand can effectively control thoroughly not cause because sterilization during plastic sheeting is removed contamination pathogenic infection microorganism to leak the generation of accident, on the other hand also can reduce the generation of the cross infection accident brought because operated by personnel is improper to greatest extent.
