Abstract

The utility model relates to an open type ultraclean box which is widely used for the space environment of the aseptic operation of biological engineering and other industry. The utility model has the advantages that the effect of an ultraclean working bench can be realized, manufacturing cost is low, the defects of an immunization box are overcome, and the utility model can be put into large-scale production and can operate continuously. The utility model is composed of a control box (8) and an aseptic airflow generator, and has no stimulation to the skin of long-term operating staff.

Description

Open ultra-clean case

One, technical field:

Open ultra-clean case described in the utility model, used aseptic technique case when belonging to microorganism, bacterization and cultivating is widely used in the environment that biotechnology and other industry relate to aseptic technique.

Two, background technology:

The existing acquisition that is used for biotechnology sterilized space environment mainly is to obtain by Bechtop and two kinds of devices of inoculation tank.Bechtop costs an arm and a leg, and the general individual family is difficult to bear; And because the germ-free air flow that strainer produces is faint, must in the clean room of the relative immobilized of air, just can carry out, be unfavorable for open-sky technique.Inoculation tank is by the medicament fumigating sterilization and disinfection, because of not thorough, must cooperate the flame of spirit lamp to use during operation, because the zone is too little, be inconvenient to operate, more incompatible to the tyro, be unfavorable for scale production and work continuously that formaldehyde and potassium permanganate have damage to long-term operate continuously personnel's skin on hand simultaneously.

Three, summary of the invention:

The purpose of this utility model provides a kind of open ultra-clean case, solves above-mentioned defective, and it can strictness kill other assorted bacterium, does not have any drug contamination again, and is the open aseptic area that can work continuously.

Open ultra-clean case described in the utility model is made up of operation box and germ-free air flow producer.The germ-free air flow producer is made of gas blower, sterilization tank, germ-free air flow communicating pipe again, and sterilization tank is made the wide-necked bottle shape with metallic substance or glass, is provided with oblique blast pipe in the suitable position of sterilization tank body, and an end of blast pipe inserts in the jar.The horizontal pipeline section in outer end links to each other with the air outlet of gas blower.Jar eck at sterilization tank is provided with 3-5 layer plastics gauze, make the filtering net stenlizing layer, the jar mouth was connected with germ-free air flow communicating pipe, the end of germ-free air flow communicating pipe is made garden shape, the other end is made the rectangular horn degree of lip-rounding and is connected with the squab panel of operation box, operation box is similar to common inoculation tank, the rectangular box of forming by four pillars (pin) and skeleton construction, casing is by operate tablet, wall and case lid are formed, and have on the squab panel of casing and the germ-free air flow communicating pipe mouth that matches of hydraucone, and are attached thereto, respectively have the hole on the left and right sides wallboard of casing, left side wall opening is an opening for feed, and the hole that right wallboard is opened is a discharge port, two mouthfuls of doors that all are provided with the energy switch.Have two garden shape handle holes on the wall of the front of casing (operating surface), be fixed with gentle matter oversleeve on two holes, the end face of casing is provided with retaining plate, connect a beveled glass doorframe on the retaining plate, glass door frame can open and close up and down, make after closing and be in air-tight state in the casing, during use, add clean water in sterilization tank, the water yield is an appropriateness to flood blast pipe the inner, add sterilant, sterilant requires wide spectrum, and sterilization is thorough, fast, harmless, its aqueous solution is to the livestock and poultry toxicological harmless, 3-5 layer plastics gauze is fixed on the disinfection tank neck, the glass cover of shutoff operation case and left and right sides feed inlet and outlet door.Open gas blower shut down in 2 minutes; according to a conventional method instrument and article are put into operation box; light smoke disinfectant to disinfection in the casing, after smog disappears, open gas blower; operation routinely; but close the discharge port door during charging, close the opening for feed door during discharging and since in the disinfection tank constantly in operation box in the supply germ-free air flow case air pressure greater than normal pressure; outside air can not enter operation box, has guaranteed in the case aseptic.Use this open ultra-clean case, do not operated what restriction of thing, be convenient to large batch of production, non-stimulated to operator's prolonged operation to skin.Can reach the effect of Bechtop fully, cost is but very low.

Four, description of drawings:

Accompanying drawing 1 is the structural representation of open ultra-clean case.

Among Fig. 1: 1-disinfection tank, 2-blast pipe, 3-sterilant soup, 4-gas blower, 5-filtration sterilization net, 6-germ-free air flow communicating pipe, the aseptic gas admission port of 7-, 8-operation casing, 9-handle hole, 10-glass door closure, 11-discharge port, 12-opening for feed.

Five, embodiment:

Contrast accompanying drawing 1 explanation open ultra-clean case described in the utility model, it partly is made up of operation box 8 and germ-free air flow producer two, the germ-free air flow producer is provided with opening for feed 12 and discharge port 11 by the two ends of sterilization tank 1 and blast pipe 2, sterilization soup 3, gas blower 4, filtration sterilization net 5, germ-free air flow communicating pipe 6, aseptic gas admission port 7, operation box 8, but two material mouths are equipped with the door of switch, the front of operation box is provided with handle hole 9, the inclined-plane of operation box is provided with glass door closure (10), and door closure can switch.
