Abstract
The utility model relates to a device which is used for disinfecting and sterilizing articles, such as medical utensils, medicine packing containers, etc. The utility model uses peroxyacetic acid as sterilizing agents. An article which needs to be carried out the sterilizing treatment is put in a pressure resistant sterilizing box 6, and one side of the pressure resistant sterilizing box is connected with a peroxyacetic acid gas generator 12 through an input pipe which is provided with a control valve. The upper end of the generator is provided with a medicine feeding funnel 10. The other end of the sterilizing box is connected with a vacuum buffer tank 2 through an output pipe which is provided with a control valve. The vacuum buffer tank is provided with a vacuum machine 1. Peroxyacetic acid gas is convenient to be sucked into the sterilizing box and sucked out from the sterilizing box, and the purpose that the articles are disinfected and sterilized in a batch way can be realized.
Description
This utility model relates to the sterilizing installation of a kind of medical treatment, medical utensil, is specially adapted to a kind of device of drug packaging sterilizing containers.
At present, the method for disinfection and sterilization of medical apparatus and medical packaging container is had numerous species, modal is the steaming and decocting under high pressure sterilization.Along with the continuous development of science, as new biocide, more and more be subject to people's attention with peracetic acid (Peracetic acid).This biocide can be used for the sterilization that carries out disinfection of heat-resisting, heat labile article article, even can be used for the sterilization that carries out disinfection of vegetable, melon and fruit and human body skin mucosa, particularly has more unique advantage with it as the sterilization of thermo-labile article.With this biocide to article carry out disinfection the sterilization the most frequently used method have: infusion method, nebulization and fumigation and steaming method etc.And to the sterilization of medical apparatus and medical packaging container, using more is fumigation and steaming method.But also not used so far fluoroacetic acid do biocide to medical apparatus and medical packaging container carry out in enormous quantities, the sterilizing installation of high-effective disinfecting.
The purpose of this utility model: be to provide a kind of with peracetic acid do biocide to medical apparatus and medical packaging container can carry out disinfection in batch sterilization treatment, the high-efficiency steriliging device.
This utility model is achieved in that it comprises a withstand voltage sterilization tank, one side of this withstand voltage sterilization tank is connected with the peracetic acid gas generator through the input pipe of band control valve, and the upper end of its peracetic acid gas generator is equipped with the dosing funnel through the connection tube that has by-pass valve control; And be connected with a vacuum buffer tank at the outlet tube of opposite side through having control valve of withstand voltage sterilization tank, this vacuum buffer tank has the vacuum unit and constitutes.
The operation principle of this steriliser is: with needs carry out disinfection the sterilization medical apparatus or drug container put in the withstand voltage sterilization tank, will be by the vacuum unit through vacuum buffer tank, connecting pipe, in the withstand voltage sterilization tank of peracetic acid gas suction that will be produced by the peracetic acid gas generator, the article that the need sterilization is handled are handled.Also to carry out humidification in case of necessity, to be adapted to different demands to various sterilisation of objects sterilizations to withstand voltage sterilization tank.Used peracetic acid gas is by handling in the vacuum unit suction vacuum buffer tank, in order to avoid environment is produced pollution.
Because this utility model is by a peracetic acid gas generator peracetic acid liquid to be made gas, make it to enter in the withstand voltage sterilization tank being placed on article in the withstand voltage sterilization tank sterilization treatment that carries out disinfection, through after the sterilization treatment of certain hour, will handle in the peracetic acid suction vacuum buffer tank again by the vacuum unit.Whole sterilization process can be finished automatically, and can need the article of sterilization to be carried out to sterilization treatment in bulk, its high efficiency, and sterilization effect is good, can carry out mass disposal, to be adapted to produce in enormous quantities the needs of medical apparatus or a large amount of fill medical drugses.The water of used peracetic acid gas in vacuum buffer tank carries out acidification, has prevented that peracetic acid from discharging in air, has protected environment again.
Fig. 1: be structure principle chart of the present utility model;
Below in conjunction with accompanying drawing this utility model is described in detail.
The said withstand voltage sterilization tank 6 of this utility model is a kind of closed pressure vessels with cover.Side at withstand voltage sterilization tank 6 is connected with peracetic acid gas generator 12 through the input pipe 11 of band control valve, the upper end of peracetic acid gas generator 12 is equipped with dosing funnel 10 through the connection tube of band control valve, so that annotate peracetic acid in gas generator 12.Opposite side at withstand voltage sterilization tank 6 is connected with vacuum buffer tank 2 through the outlet tube 3 of band control valve, on its vacuum buffer tank 2 vacuum unit 1 is installed, by vacuum unit 1, gas in the withstand voltage sterilization tank 6 can be evacuated on the one hand, the peracetic acid gas that the peracetic acid gas generator is produced is inhaled into withstand voltage sterilization tank 6; On the other hand, the peracetic acid gas after the sterilization is released from withstand voltage sterilization tank 6.
In order to make withstand voltage sterilization tank 6 that sterilization effect preferably be arranged, on withstand voltage sterilization tank 6, heater can be installed, the temperature when controlling these withstand voltage sterilization tank 6 sterilizations.This heater can be an electric heater, also can be combustible thermal source heating, as gas furnace, can also be the pipeline medium heating.If this heater is the pipeline medium heating, can be provided with heat(ing) coil so on the inwall of this withstand voltage sterilization tank 6 or withstand voltage sterilization be made the two-layer stratigraphic structure of forming by inner bag 7 and outer wall 8, promptly be provided with dielectric cavity 16 between inner bag 7 and outer wall 8, this dielectric cavity 16 is connected to form with the thermal medium source through thermal medium inlet pipe 9 and thermal medium exit tube 4.So just can be according to different requirements to the sterilization of sterilisation of objects such as medical apparatus or drug packaging container, in the dielectric cavity 16 of withstand voltage sterilization tank 6, charge into the thermal medium of different temperatures, to control the temperature in the withstand voltage sterilization tank 6, to reach sterilization effect preferably.Here said thermal medium can be a hot water, also can hot water and steam or other fluid after being heated.The temperature of it is withstand voltage sterilization tank 6 can be controlled automatically by control instrument 5.
For peracetic acid gas generator 12, to vaporize in order to make peracetic acid soln, its peracetic acid gas generator 12 also has the heating thermal source.This thermal source can be an electric heater, also can be fuel heater or pipeline medium heater etc.If thermal source is an electric heater, this electric heater is fixedly mounted on the bottom of peracetic acid gas generator (12).If this heater or pipeline medium heating can add at the inwall of peracetic acid gas generator 12 and establish the medium coil pipe in the layer, make thermal medium flow through this coil pipe peracetic acid gas generator 12 is heated.Peracetic acid gas generator 12 can also be made to have and constitute by gallbladder and shell, have sealed cavity 15 double-deckers in the middle of it, medium input pipe 13 and the medium outlet tube 14 of this cavity 15 through being fixedly mounted on the shell is connected to form with the thermal medium source.By the heating-up temperature of control thermal medium and the flow velocity of inflow cavity 15 etc., control the internal temperature of peracetic acid gas generator, realize industrial production requirement.
