Blood storage bank system and access control method

Abstract

The invention provides a blood storage bank system and an access control method. The problems of high refrigeration energy consumption, medical accidents caused by human error defects, low working efficiency, high labor intensity and the like of the conventional manual storage and management of a blood bank are solved. The blood storage bank system comprises a storage tank with a cold storage cavity, wherein the storage tank is provided with storage windows and taking windows; a material shelf is arranged in the storage tank; advancing mechanical arms are arranged on the material shelf; the storage tank is communicated with heat exchange units; temperature sensors are arranged in the cold storage cavity of the storage tank; and the heat exchange units, the temperature sensors and the mechanical arms are in control connection with a computer controller. The access control method comprises the following steps of 1) scanning stored blood bags; 2) inputting data information; 3) storing the blood bags under control; 4) making blood bag taking records; 5) taking out the blood bags under control; 6) locking the windows; 7) regulating and controlling cold storage temperature; and 8) giving an alarm when the temperature is abnormal. According to the system and the method, the blood bank is automatically monitored, the safe access and use of the blood bank is ensured, and the cold storage temperature is accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and relates to a refrigeration device for storing blood, in particular to a blood storage banking system and an access control method. Background technique [0002] Blood is usually stored in blood banks, kept by medical units, blood banks, or the Red Cross, in case someone needs a transfusion. Since the clinical demand for blood is uncertain, and the types of blood or blood components required are also different, low-temperature refrigeration technology that prolongs the shelf life of blood and blood components has received more and more attention. [0003] Blood refrigeration can prevent coagulation, ensure the nutrition needed for cell metabolism, prolong the life of the body in the blood outside the human body, and ensure that it can perform corresponding functions after being transfused to the patient. However, due to the different characteristics of various blood cell bodie...

Problems solved by technology

[0005] The existing cryogenic refrigeration and management are all manual operations, requiring workers to manually enter the refrigerator to take out the blood

Manual access has great disadvantages in blood management

First of all, it will lead to a large amount of heat exchange between the cold storage and the outside world, which will inevitably increase the cooling capacity, increase energy consumption, and have an adverse effect on blood storage; secondly, manual blood storage will have major defects in information transmission and information processing. For example, wrong information, wrong storage location, wrong blood type, failure to timely give blood safety reminders that are about to expire, failure to timely warn blood safety stocks, etc., resulting in delays in treatment of patients, or medical accidents that bring danger to patients' lives; moreover , storage and management are all manually operated, which takes up a lot of manpower and energy, making the operator labor-intensive and under great pressure
