Selecting Scientific Refrigeration Equipment

Selecting Scientific Refrigeration EquipmentScientific refrigeration equipment includes refrigerators and freezers used to store vaccines, pharmaceuticals, biological samples and similar temperature-sensitive products and specimens for healthcare, R&D and related applications.  Scientific refrigerators and freezers have critical performance requirements generally unmet by residential and commercial refrigeration systems.  For this reason they are highly recommended to protect contents that lose potency or are otherwise compromised by what are called temperature excursions above or below recommended storage settings. Therefore, selecting scientific refrigeration equipment for your needs is key.

Correct storage temperatures are usually recommended by professional or government organizations.  The CDC, for example, recommends in its 2016 Vaccine Storage and Handling Toolkit that frozen vaccines be stored between -50⁰ and -15⁰C (-58⁰ and + 5⁰F); refrigerated vaccines should be stored at 2⁰ and 8⁰C (36⁰ and 46⁰ F).  Vaccine manufacturers indicate correct storage temperatures that should apply along what is called the “cold chain” extending from the … Read the rest

Solar Power to the Rescue of Hospitals in Developing Countries

WE CARE Solar works with hospitals in developing countries helping them implement reliable electrical supplies for powering hospital wards and equipment. In this video the the founder walks us through the difficulties faced by healthcare centers in Nigeria. Due to the lack of continuous power supply traditional blood bank refrigerators are unfeasible. WE CARE Solar helped these centers deploy solar powered electrical systems that brought reliable power to power equipment like sonograms and solar powered blood bank refrigerators. They also supplied walkie talkies that were recharged by electricity from solar power.… Read the rest

Processing & Storing Blood Products

Before blood and blood products like plasma can be stored in a blood bank refrigerator or a plasma freezer.  It needs to go through a number of processes.  This video takes you through the entire process from the time the blood is received in the lab.  Each bag of blood is spun in a centrifuge to separate out the red blood cells, platelets, and plasma.   Subsequently the red blood cells are further processed to separate out the white blood cells before being stored.  The plasma is frozen in the freezer and has a shelf life of up to 12 months.  The platelets need to be used within five days.… Read the rest

Energy Supply Crucial for Blood Banks

Blood bank refrigerators need a continuous supply of electricity to retain viability of blood products

This report from USAID looks at the options for improving power supply to health care centers in Haiti. The study was commissioned by PEFAR (President’s Emergency Plan for AIDS Relief) as they’d found their AIDS treatment programs being severely hampered by inadequate power supply.  The USAID team investigated several centers and came up with a series of recommendations to help PEFAR address the energy problem.  Key recommendations included identifying competent management teams at the centers before investing in any energy improvement plan.  In addition to that they also recommended the use of right sized blood bank refrigerators to optimize the use of electricity.  While many of the larger hospitals had the required infrastructure what they lacked was the technical ability.  The report recommended that PEFAR invest in training the on-site electricity maintenance staff and to … Read the rest

Blood Bank Refrigerators in the Fight Against AIDs

Blood bank refrigerators play a crucial role in the fight of against AIDS

This report documents the success of the PEFAR (President’s Emergency Plan for AIDS Relief) program in Botswana’s fight against AIDS.  Over 80% of those needing anti-retroviral vaccines where covered in the program while mother to child transmission was slashed from a massive 40% to less than 7%.  The PEFAR funding helped the Botswana government beef up its infrastructure to fight AIDs. This included the purchse of blood bank refrigerators and a multi-pronged intervention strategy that heaped rich dividends.  A total of $39 million was spent covering prevention programs, care and counselling, treatment therapies, and staffing and administrative overheads. The success of the program has drawn international attention and praise for Botswana’s multisectoral approach to fighting AIDS.

Blood Transfusion Services during Natural Disasters

Blood bank refrigerators are critical to blood transfusion services during natural disasters

Blood bank refrigerators are critical to blood transfusion services during natural disasters

This study investigates the performance of emergency blood transfusion services during the 2005 earthquake that hit the Himalayan areas of Kashmir and Hazara.  In all an estimated seventy three thousand people were killed and on a disaster of this scale establishing blood banks in the disaster area in a timely manner was a huge challenge. The investigations revealed that of the seven major hospitals only three had a blood transfusion service that was functional.  The major obstacle was the availability of basic infrastructure including blood bank refrigerators.  The study found that only three hospitals had the refrigerators but with limited storage space. Aftershocks, a total breakdown of infrastructure, coupled with frequent power failures acerbated the situation.  The study recommended setting up mobile blood banks, a national level organization for blood transfusion services, and implementing a quality assurance program … Read the rest
