Sterile soft package isolator

Abstract

The invention discloses a sterile soft package isolator which comprises an outer frame support. An air feeding and discharging box and a transparent PVC (polyvinyl chloride) flexible film isolation package, an operating glove and a delivery bin are arranged on the transparent PVC flexible film isolation package and connected with the air feeding and discharging box through an air feeding pipe andan air discharging pipe, pipeline-type efficient filters and manual adjusting valves are arranged on pipe bodies of the air feeding pipe and the air discharging pipe, the air feeding and discharging box comprises an air feeding primary filter, an air feeding fan, an air feeding efficient filter, a concentrated air feeding chamber, a concentrated air discharging chamber, an air discharging fan, anexternal air discharging connector, an all-network wireless communication module, a measurement sensor, an integrated control module, a UPS (uninterrupted power supply) and the like. The sterile softpackage isolator is conveniently and rapidly assembled and disassembled, various operations of the workers are facilitated, pollution risks are low, collapse cannot easily generated, manufacturing andtransporting cost is low, the sterile soft package isolator has intelligent control and remote control functions, and healthy living environments can be created for sterile animals.

Description

technical field [0001] The invention relates to an isolator, in particular to an aseptic soft bag isolator for raising aseptic animals in experiments. Background technique [0002] Sterile animals refer to animals that cannot detect any living microorganisms and parasites in any part of the animal body or outside the body using existing detection techniques. This animal must be born sterile and kept in a sterile isolator. . [0003] The current aseptic isolator is generally composed of an outer frame bracket, an isolation bag, a transfer cabin, an air supply and exhaust system, and an air supply and exhaust filter. A number of feeding racks and corresponding number of feeding boxes were placed in the isolation bag for aseptic feeding. But present aseptic isolator has following shortcoming: 1. The material of isolation bag is too hard (especially sleeve tube) is unfavorable for operation. 2. Ordinary high-efficiency filters are installed at the air outlet of the fan, far a...

AI Technical Summary

Problems solved by technology

However, the current aseptic isolator has the following disadvantages: 1. The material of the isolation bag is too hard (especially the sleeve) which is not conducive to operation

2. Ordinary high-efficiency filters are installed at the air outlet of the fan, far away from the isolation package. When a fault occurs, due to the long pipeline and joints, there is a risk of pollution. In addition, the upper and lower layers of the package share a high-efficiency filter. Special circumstances There is a possibility of mutual infection

3. There is generally no high-efficiency filter at the exhaust end, and there is a risk of pollution when there is a failure

4. During the breeding process, the important air quality indicators inside the isolation bag are not monitored (temperature, humidity, oxygen content, ammonia concentration, etc.), and the comfort of the animal’s life cannot be reflected. The animal is in a harsh environment or an environment that affects its survival. life cannot be known in advance

5. There is no valve control in the air supply and exhaust pipes, the isolation package cannot keep the pressure in case of failure, the soft isolation package will collapse, and there is no time for emergency treatment

6. Without intelligent control, the pressure condition is determined only by the expansion degree of the isolation bag

7. No remote monitoring function
