Description

Portable planktonic bacteria sampling monitoring platform

Technical Field

The utility model relates to a monitoring platform, especially a portable planktonic fungus sampling monitoring platform.

Background

The production of the medicines should execute the "quality management standards for medicine production" (revised in 2010), the production conditions must meet the corresponding cleanliness levels (such as a level a, a level B, a level C and a level D), and the items such as temperature, humidity, pressure difference, deposited bacteria, planktonic bacteria, dust particles, illumination, noise, ventilation times, self-cleaning time and the like are regularly monitored. Planktonic bacteria (air viable microorganisms) refer to viable microorganism particles suspended in the air in a medical clean room, and the viable microorganism particles are propagated to the visible colony number under appropriate growth conditions through a special culture medium. Generally, a single-stage or multi-stage impact sampler, a centrifugal sampler or a filtering sampler is used, sampling points are generally more than 2 points according to the area size of a clean room (area), and should be uniformly arranged on a high plane 0.8m away from the ground, each point samples for 1 time, and the sampling amount is generally different from 100L, 200L, 300L and 1000L according to the clean level.

At present, the monitoring basis of planktonic bacteria in a clean room (area) of a pharmaceutical enterprise is 'drug production quality management standard' (revised in 2010), 'test method of planktonic bacteria in a clean room (area) of pharmaceutical industry' (GB/T162932010), 'construction and acceptance standard of clean room' (GB 505912010), and the like, and the pharmaceutical enterprise is definitely stipulated to monitor planktonic bacteria in the clean room (area) regularly, find bad trends or abnormal conditions in time, so that corrective measures and preventive measures are taken to prevent the clean room (area) from being polluted, and effectively guarantee the quality of medicines. When the planktonic bacteria monitoring is needed to be carried out on the clean room (area), firstly, a culture dish, a support and a special detector for planktonic bacteria required by the planktonic bacteria monitoring are disinfected through a logistics channel of the clean room and then transferred into the clean room, then, detection personnel enter the clean room through a pedestrian flow channel of the clean room, and before, objects for detection are transferred into a detection area. One clean room performs sampling monitoring in the order of the clean rooms from inside to outside. Before sampling, fixing the planktonic bacteria detector (sampling flow is generally 100L/min + -5%) on the support table, the height of the support table from the ground is generally 0.8m, placing the culture dishAnd (4) putting the culture dish on the planktonic bacteria detector, uncovering the culture dish cover, and starting the planktonic bacteria detector until the sampling is finished. Each sampling point generally needs 5-15 min, and each clean room sampling point generally has more than 2 sampling points. After the detection of one clean room is finished, the culture dish, the bracket and the special detection instrument for the planktonic bacteria are moved to another clean room to carry out the same sampling and monitoring operation. Such a clean room is sampled and monitored in the order of numbering until the monitoring and sampling are completed. In order to avoid the influence caused by the moving process of the culture dish, a negative control test is carried out at the same time, the negative control test is operated in the same way as the monitoring sampling dish but does not need to be exposed for sampling, and finally the negative control test and the sampled culture dish are put into an incubator together for inverted culture, and the incubator is put into 2 hours for culture after sampling. Counting the colonies from the sampled culture dish and calculating the average colony count at each sampling point, which should be below the limit of the selected evaluation standard (grade A should grow aseptically, grade B should not exceed 10 cfu/m)³The C-grade should not exceed 100cfu/m³D class should not exceed 200cfu/m³) Negative control dishes should be grown aseptically. Usually, a clean production workshop has tens of hundreds of clean rooms (regions), the time of more than two days is needed for once sampling monitoring accumulation, the operation is time-consuming and labor-consuming, the culture dish, the bracket and the special detector for planktonic bacteria are moved, the culture dish is easily polluted to cause unreal sampling monitoring results and the culture dish is broken and lost, and the special detector for planktonic bacteria is frequently moved to influence the reliability of the monitoring results. These problems have not been solved well.

Disclosure of Invention

There is sampling monitoring time long when monitoring to present toilet (district) planktonic fungus, wastes time and energy, and the operation is numerous and diverse, moves culture dish, support, the special detector in-process of planktonic fungus, still leads to the culture dish to be contaminated easily and causes that sampling monitoring result is unreal, the culture dish is broken and the loss, and the special detector of planktonic fungus frequently moves and influences the problem of monitoring result reliability, the utility model discloses a portable planktonic fungus sampling monitoring platform.

A movable planktonic fungus sampling and monitoring platform is characterized by comprising a stainless steel cart, a cart handle, a special planktonic fungus detector, a baffle plate, an upper platen, a lower platen, a storage cabinet A, a storage cabinet B, universal wheels, directional wheels, partition plates and a culture dish (a plurality). The stainless steel platform is made of 304 stainless steel materials, the length is 0.9m, the width is 0.3m, the height is 0.8m, the front wheels are installed as directional wheels, and the rear wheels are installed as switchable universal wheels; the stainless steel platform is provided with an upper layer and a lower layer, and a baffle plate with the height of 10cm is arranged around the upper layer; the special detector of upper strata installation planktonic fungus, the lower floor are two independent ingathering cabinets, and one is used for placing the culture dish before the sampling, and another is used for placing culture dish and negative control culture dish after the sampling.

The utility model relates to a portable planktonic fungus sampling monitoring platform's theory of operation is: when need regularly to clean room (district) planktonic fungus monitor, easily promote planktonic fungus sampling test platform and pass through the workshop commodity circulation passageway after cleaning and disinfecting, promote to the production operation room, according to each clean room (district) sampling point arrangement diagram of compiling in advance, monitor the sampling to a check point in clean room (district), until all accomplish in all clean room (district) planktonic fungus sampling point sample back, put into the incubator with sampling culture dish and negative control culture dish and cultivate and have planktonic fungus detection report.

The utility model relates to a portable planktonic fungus sampling monitoring platform's beneficial effect is: the platform is easy to install and convenient and fast to move, equipment required for monitoring planktonic bacteria, such as a culture dish and a planktonic bacteria detector, are effectively ensured to be intact, and risks caused by moving the sampling culture dish and the planktonic bacteria detector by chance are reduced; this platform convenient to use, labour saving and time saving has improved work efficiency, has improved the accuracy of planktonic bacteria monitoring result.
