Description
Technical field
This utility model relates to a kind of steam autoclave that is applicable to the steam sterilization box of hospital's sterilization of medical instrument and has the steam sterilization box.
Background technology
At present, steam autoclave is widely used in the sterilization of hospital's medical apparatus and instruments, but because the discharging modes of air and the restriction of degree, sterilization intensification and temperature fall time are long, again because the apparatus of sterilization has certain distance by the sterilization point to the instrumentation point, for preventing pollution once more in transit, all need sterilized instrument is carried out drying and parcel, the parcel mode is wrapped up and sterilization back parcel the preceding parcel of sterilization before generally adopting sterilization, then increased the water vapour penetration difficulty, prolonged the sterilization heating-up time, the instrument bag after the sterilization must drying can be taken out simultaneously, and parcel has increased dry difficulty, also prolong drying time, caused sterilising cycle to prolong.Sterilization back parcel, then, high to the environment cleanliness requirement owing to being the machine outer wrapping, be easy to generate secondary pollution, simultaneously, the apparatus that wrap up the sterilization back needs drying equally, makes the sterilising cycle prolongation.
The utility model content
A purpose of the present utility model is at the problems referred to above, and a kind of steam sterilization box that is applicable to hospital's sterilization of medical instrument is provided, and another purpose of the present utility model is to provide a kind of steam autoclave that has the steam sterilization box.Make sterilized instrument no longer need parcel just can implement transportation, accelerate the sterilization heating-cooling time,, alleviate medical personnel's labor intensity to shorten the sterilization time of apparatus.
For achieving the above object, the technical solution of the utility model is: a kind of steam sterilization box, comprise box body and lid, described lid is fastened on box body, between box body and lid, be provided with hermetically-sealed construction and locker, on box body or lid, also be provided with the air feed duct and the duct of bleeding, on this air feed duct and the duct of bleeding, be provided with closure member.
The input port in described air feed duct is located at a side of lid, and the delivery outlet in the described duct of bleeding is located at the opposite side of lid.Described closure member can be check valve, described closure member also can be made of spool, valve seat and back-moving spring, spool is positioned at an end of back-moving spring and is closed on the valve opening of valve seat, the lateral hole wall of described spool offers the passage that is communicated in the lid inboard, and this passage constitutes the part in the described air feed duct or the duct of bleeding.
In described box body, can be provided with support body.
This utility model also provides a kind of steam autoclave that has above-mentioned steam sterilization box, in steam autoclave, be provided with the cavity that at least one holds the steam sterilization box, described steam sterilization box is installed in this cavity, in described cavity, be provided with and the steam sterilization box air feed duct and air supply pipe and the exhaust tube that the duct is corresponding and match of bleeding, described air supply pipe be connected in parallel steam generator and air filter, described exhaust tube be connected in parallel an exhaustor and a vacuum pump; Be respectively equipped with stop valve between air supply pipe and the steam generator and between air supply pipe and the air filter, be respectively equipped with stop valve at the front end of exhaustor and vacuum pump.
Between described vacuum pump and stop valve, also be provided with the steam chiller.
Described stop valve is automatically controlled stop valve.
Described air supply pipe and exhaust tube also comprise heating pipe joint and exhaust tube joint, and this heating pipe joint and exhaust tube joint are connected with the described air feed duct and the duct of bleeding respectively, and at lateral opening, faces end head plugging.
Because this utility model is made up of one or more movably steam sterilization boxes and steam autoclave main body.Movably sterilization cassette can be connected with the steriliser main body quickly and easily, it is connected with exhaust tube with the air supply pipe of steam autoclave with the duct of bleeding by making the air feed duct, realization is to the quick air feed of sterilization cassette and bleeding, because the common relatively steriliser combustion space of sterilization cassette is little, realize the full of evacuation and steam easily, and intensification and temperature fall time that special air feed that steriliser adopts and exhaust mode have shortened apparatus, again because the closure member of sterilization cassette makes can close automatically behind its air supply pipe and the exhaust tube disengaging sterilization cassette, cut off the circulation of sterilization cassette and extraneous air, make the apparatus after the sterilization in box, realize aseptic preservation, convenient transportation, avoid the trouble of sterilized instrument parcel, reduced the channel of secondary pollution.In addition, the apparatus that adopts this sterilization cassette to preserve after sterilizing does not have dry requirement to apparatus, as long as can guarantee air supply opening and the dry sealing of bleeding point, has reduced the dry required time of apparatus.The both sides that the delivery outlet in the input port in air feed duct and the duct of bleeding sets up the steam sterilization box separately can make air feed, bleed evenly, and first evacuation can be passed through in addition in no dead angle, and the way of the steam that reinjects makes the distribution of steam in the steam sterilization box more even.Described closure member adopts spool, valve component can make the air vent road and open when air supply pipe and exhaust tube insertion in the duct of bleeding, and closes when extracting, and guarantees sealing effect.The support body that is provided with in the steam sterilization box can make things convenient for putting of medical apparatus and instruments, and makes vapor stream clear and coherent smooth.
When can preventing at evacuation, the steam chiller that is provided with between vacuum pump and the stop valve, influences the life-span of vacuum pump with in the steam suction vacuum pump.Stop valve adopts automatically controlled stop valve can realize automatic control.
