1. Demand analysis
Vaccines are special medicines. There are strict requirements for refrigeration and heat preservation during transportation and storage. Excessively high or low temperatures may affect the quality of vaccines and even lead to failure. Therefore, the cold chain monitoring method of manual measurement and regular reporting on paper records can no longer fully meet the management needs of modern biological products storage and transportation.
Refrigerators or freezers are generally used to store vaccines. In some emergency situations, such as power failure, the refrigeration equipment will be out of control. Post-processing will cause damage to a large number of vaccines. If it is interrupted intermittently in the middle of the night It may not be detected afterwards, but the vaccine in it may have been affected.
Vaccine delivery mainly uses refrigerated trucks, refrigerated boxes, refrigerated backpacks, etc.; especially for long-distance vaccine transportation in remote rural areas, refrigerated bags must be stored for a few days, infectious disease prevention and control vaccination during natural disasters, and all other unpredictable events. Such as the application of emergency vaccination during public health emergency, terrorist attack, serious power failure, etc.
In order to ensure the quality of the vaccine before injection and guarantee the results of immunization, the real-time monitoring of temperature and humidity records is more important during the cold chain storage and transportation of vaccines, vaccines and other biological products from the finished product warehouse of the pharmaceutical factory, delivery, and population inoculation. .
2. Program overview
Kong Cheng cold chain wireless temperature and humidity real-time monitoring and management platform (hereinafter referred to as the platform) uses advanced data collection and communication technology and big data cloud platform to develop a set of integrated management of warehouses, vehicles, boxes, and backpacks specifically for cold chain vaccines The wireless real-time monitoring and management system; to achieve a seamless connection with the original child vaccination information management system, vaccine storage management system and other related systems interconnection and information sharing.
2.1 System architecture
2.2 System composition
The temperature and humidity collector (2) is applied to the temperature and humidity collection of various levels of cold storage, refrigerated trucks, incubators, refrigerated backpacks, etc. It can wirelessly collect the temperature and humidity of the location in real time, and send the temperature and humidity in real time through the wireless temperature collector (1). Humidity data and alarm information are sent to the platform covering the entire cold chain process, and portable printers can also be connected; of course, delivery notes and temperature and humidity records can also be printed and transmitted through the Kongcheng cold chain handset (3).
It realizes automatic real-time monitoring of temperature and humidity, the main measurement parameter in the whole process of vaccine cold chain storage, transportation and use. Through the combination with GPRS function, it can check the changes of parameters and location and send out alarms, which is reliable in real-time transmission for the platform. Data provides a chain of data evidence to ensure the quality and quality assessment of vaccines; PCs and mobile apps on the platform can directly access the stored data through wireless or private networks and can analyze the data to form reports;
2.3 Business Process
2.4 Application scenarios
Abnormal refrigeration temperature data means that the temperature of the vaccine refrigeration equipment is less than 4 degrees Celsius or greater than 8 degrees Celsius. The vaccine refrigeration temperature is suitably in the range of 4-8 degrees Celsius, preferably 6 degrees Celsius, and less preferred such as 5 and 7 degrees Celsius. , Or not an integer; the abnormal alarm value is set to “5 degrees Celsius and “7 degrees Celsius by default, and the alarm threshold can also be customized.
2.4.1 Cold storage storage
As shown below
Install temperature and humidity collectors (2) in the refrigerator and refrigerator or freezer respectively, and send the location and temperature and humidity records (less than 5 minutes) to the temperature collector (1), so that they are sent to the Platform; (PCmobile phone) Log in to the platform to view the temperature changes of each storage vessel and receive alarm information in real time; if there is an abnormality, the warehouse manager or duty officer will take immediate measures, including manual temperature adjustment and communication to maintenance personnel.
2.4.2 Refrigerated truck (transportation)
2.4.2.1 Point-to-point transportation of refrigerated trucks
When leaving the warehouse, the temperature collector (1) imports outbound order information and real-time temperature and humidity records, and the delivery person (or driver) installs the wireless temperature collector (1) in the cab, corresponding to the respective insulation in the associated refrigerated vehicle The temperature collector (2) in the box transmits the location and temperature and humidity records to the platform in real time through the mobile phone network and base station, and at the same time, receives the alarm information of the abnormal temperature and humidity of the platform, so as to take necessary measures to ensure the temperature and humidity in the incubator When reaching the standard and arriving at the station, the delivery note and temperature and humidity records can be transmitted to the portable printer or the outlet printer through the temperature collector (1), and at the same time, print it or sign for the receiver.
2.4.2.2 Multi-site distribution and transportation of refrigerated trucks
When leaving the warehouse, import the outgoing order information and real-time temperature and humidity records, and the delivery personnel (or driver) install the temperature collector (1) in each incubator in the corresponding refrigerated truck, and send it to the platform in real time through the mobile phone network and the base station Transmit the location and temperature and humidity records, and at the same time, receive the alarm information of the abnormal temperature and humidity of the platform, so as to take necessary measures to ensure that the temperature and humidity in the incubator meet the standard. Go to the first station, take out the corresponding temperature collector (2) and send it. The manifest and temperature and humidity are recorded to the portable printer or the outlet printer, and at the same time printed to the receiving staff to sign for receipt, continue to the second stop;
2.4.3 Refrigerated bag
2.4.3.1 Refrigerated packages need to be delivered exclusively at a single outlet
When leaving the warehouse, the temperature and humidity collector (1) imports the outgoing order information and real-time temperature and humidity records, and the delivery staff also puts the temperature and humidity collector (1) in the refrigerated bag, and the temperature and humidity collector (1) uses the mobile phone network And the base station transmits the location and temperature and humidity records to the platform in real time. At the same time, it receives the alarm information of the abnormal temperature and humidity of the platform. The delivery personnel can take necessary measures to ensure that the temperature and humidity in the refrigerated bag reach the standard. After arriving, take out the temperature and humidity collector (1) Transmit the delivery note and the temperature and humidity records to a portable printer or an outlet printer, and print them to the receiving staff for signing.
2.4.3.1 Multi-site distribution
When leaving the warehouse, the handheld machine imports the outbound order information and real-time temperature and humidity records, and puts them on the body; the delivery staff also puts the temperature and humidity collector (1) in the refrigerated bag, and the handheld machine transmits to the platform in real time through the mobile phone network and the base station Location and temperature and humidity records, and at the same time, receive the alarm information of abnormal temperature and humidity on the platform, and the delivery personnel can take necessary measures to ensure that the temperature and humidity in the refrigerated bag meet the standard. At the first station, the handheld device transmits the delivery note and temperature and humidity. Record to the portable printer or dot printer, and print it to the receiving staff to sign for receipt, continue to the second stop;
