[0002] Blood products refer to the general term for plasma protein components and formed elements of blood cells made from healthy human plasma or specifically immunized human plasma through separation, purification, or recombinant DNA technology. Most of the time from the preparation of blood products to their application to clinical patients is in the transportation process. In this process, temperature is an important factor affecting their quality. If the heat preservation is not good, it is very easy to cause the deterioration of blood products.

[0004] The above solution solves the problem in the prior art that during transportation, the heat preservation is poor and it is easy to cause the deterioration of blood products. However, the sensor unit used in this solution monitors blood products by collecting the average temperature inside the transportation carriage. The blood products in individual blood bags inside the carriage may have too high a temperature and cause deterioration. At the same time, it is not convenient to monitor the state of the blood bags, and it is difficult to avoid the situation that the blood bags are opened during transportation and the blood products therein are contaminated. Therefore, it is necessary to propose a blood product quality control and detection system to solve to a certain extent the problems in the prior art that the sensor unit monitors blood products by collecting the average temperature inside the transportation carriage, the blood products in individual blood bags inside the carriage may have too high a temperature and cause deterioration, at the same time, it is not convenient to monitor the state of the blood bags, and it is difficult to avoid the situation that the blood bags are opened during transportation and the blood products therein are contaminated. Summary of the Invention

[0005] The object of the present invention is to provide a blood product quality control and detection system to solve to a certain extent the problems in the prior art that the sensor unit monitors blood products by collecting the average temperature inside the transportation carriage, the blood products in individual blood bags inside the carriage may have too high a temperature and cause deterioration, at the same time, it is not convenient to monitor the state of the blood bags, and it is difficult to avoid the situation that the blood bags are opened during transportation and the blood products therein are contaminated.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A blood product quality control and detection system includes:

[0007] A temperature monitoring unit for collecting temperature information of the blood products;

[0008] A detection unit for collecting the opening and closing state information of the blood bags containing blood products;

[0009] A positioning unit for collecting the position information and speed information of the blood products, and calculating the time information of the whole transportation process of the blood products according to the position information and speed information;

[0010] An alarm unit for receiving the temperature information, opening and closing state information and position information, and alarming the operator according to the temperature information, opening and closing state information and time information.

[0011] Further, the alarm unit can also be used to receive the position information and update the database according to the position information and time information.

[0012] Further, the positioning unit can also be used to connect to the public network to adjust the time information.

[0013] Further, the alarm unit is also used to give a secondary alarm to the operator after the preset time ends according to the status information.

[0014] Further, it further includes a collection unit for collecting the type information of blood products, and the alarm unit alarms the operator according to the type information and the location information.

[0015] Further, it further includes a refrigeration unit for receiving the type information and the temperature information and refrigerating the blood products according to the temperature information and the type information.

[0016] Further, the alarm unit can also be used to adjust the time information according to the temperature information and alarm the operator according to the adjusted time information.

[0017] Further, the collection unit can also be used to collect the weight information during the transportation of blood products, and the alarm unit alarms the operator according to the weight information.

[0018] After adopting the above solution, the following principles and beneficial effects are achieved: Through the setting of the temperature monitoring unit and the alarm unit, this solution can monitor blood products more accurately, reducing the situation where the temperature of the blood products in individual blood bags exceeds the specified temperature and causing the blood products in that blood bag to deteriorate; through the setting of the detection unit, the monitoring of the opening and closing state of the blood bag is realized. When the blood bag is opened during transportation, an alarm is sent to the operator in a timely manner. If the operator does not process the blood bag at this time, after the expected time, an alarm is sent to the operator again to urge the operator to process the blood bag, avoiding to a certain extent the leakage of the blood products in the opened blood bag and polluting the other blood bags; through the setting of the positioning unit, the time expected to be used from the starting point to the destination is calculated in real time. When the expected use time exceeds the specified time, an alarm is given to the operator, and the expected use time can be adjusted according to the temperature change of the blood products and the real-time situation of the expected driving route, avoiding to a certain extent the situation where the actual transportation time increases due to traffic congestion on the front path and causing the blood products to deteriorate, and the deterioration speed of the blood products increases due to the increase in the temperature of the blood products, resulting in the deterioration of the blood products even though the operator delivers them within the specified time; through the setting of the collection unit, when the operator stacks different blood products together, the alarm unit alarms the operator, thereby reducing the deterioration of blood products caused by different storage temperatures of different blood products. At the same time, the alarm unit can also judge whether there is liquid leakage in the blood bag during transportation according to the initial weight and real-time weight of each blood bag and the blood products inside it, and alarm the operator in a timely manner, reducing the pollution of the surrounding blood bags by the blood bags with liquid leakage; through the setting of the refrigeration unit, after the temperature of the blood products rises above the specified temperature of this type of blood products, the blood products are cooled, thereby reducing the probability of deterioration of the blood products due to excessive temperature.

[0019] Through the settings of a temperature monitoring unit, a detection unit, an alarm unit, etc., this solution can, to a certain extent, achieve relatively accurate detection of the blood products in each blood bag, and at the same time can also detect the opening and closing conditions of each blood bag, which solves, to a certain extent, the problems existing in the prior art that the sensor unit uses the method of collecting the average temperature inside the transportation carriage to monitor the blood products, and the blood products in individual blood bags inside the carriage may have too high a temperature and cause deterioration. At the same time, it is not convenient to monitor the state of the blood bag, and it is difficult to avoid the situation that the blood bag is opened during transportation and the blood products inside are contaminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic structural diagram of an embodiment of a blood product quality control and detection system of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following is further detailed through specific embodiments:

[0022] The reference numerals in the accompanying drawings of the specification include: a refrigeration unit 1, a collection unit 2, an alarm unit 3, a temperature monitoring unit 4, a detection unit 5, and a positioning unit 6.

[0023] Embodiment 1

[0024] The embodiment is basically as shown in the attached Figure 1 figure:

[0025] A blood product quality control and detection system includes:

[0026] The temperature monitoring unit 4: includes a temperature sensor to collect the temperature of the blood products in each blood bag containing blood products during the transportation of the blood products;

[0027] The detection unit 5: includes several pairs of contacts to collect the state information of the opening and closing of the blood bags containing blood products during the transportation of the blood products;

[0028] The positioning unit 6: includes a GPS locator and a controller, and is used to collect the location where the blood products are located and the moving speed of the blood products during the transportation of the blood products, record the existing time used for the blood products to move from the starting point to the existing position, and calculate the estimated time to reach the destination according to the existing speed and the existing position. The existing time and the estimated time are added to obtain the total time expected to reach the destination. At the same time, the positioning unit 6 can also be used to connect to a public network to extend the estimated time according to accidents and the like on the path from the existing position to the destination;

[0029] For example: The time taken for the blood product to move from the starting point to the current position is A hours. At this time, there is still 1 kilometer to the destination. The speed of the blood product is 1 / B km / h, that is, it is expected to reach the destination after B hours. The existing time information is (A + B) hours. When an accident occurs on the path from the current position to the destination, this type of accident may cause traffic jams for C hours in the past. At this time, the preset time becomes (B + C) hours. The total time expected from the starting point to the destination is (A + B + C) hours.

[0030] Collection unit 2: It includes a pressure sensor to collect the type information of the blood products in each blood bag being transported and the weights of each blood bag and the blood products inside during transportation.

[0031] Alarm unit 3: It includes a controller and an alarm. It receives the temperature of the blood product, the opening and closing status of the blood bag containing the blood product, the possible transportation time of the blood product, and the weight of the blood bag and the blood product inside. When the temperature of the blood product exceeds the specified temperature, the blood bag containing the blood product is opened during transportation, and the expected transportation time of the blood product may exceed the specified time, it alarms the driver. At the same time, after the driver's transportation time of the blood product exceeds the specified time, the alarm unit 3 marks this route; when the driver enters this route again, it alarms and reminds the driver; during transportation, if the weight of the blood bag and the blood product inside becomes less and remains unchanged for a certain period of time without recovery, there may be a leak in the blood bag at this time, and it alarms the driver to prompt the driver to check the blood bag; after the driver is alarmed for the first time due to the blood bag containing the blood product being opened during transportation and the driver does not process the blood product in this blood bag, it gives a second alarm to the driver after a set time; at the same time, it can also receive the types of blood products in each blood bag. When the driver places different types of blood products together, it alarms the driver to prompt the driver to place the blood products in separate areas; the alarm unit 3 can also increase the expected transportation time after the blood product slightly exceeds the specified temperature, making it closer to the specified time faster, alarm the driver in advance, and shorten the actual transportation time.

[0032] For example: When the blood product is liquid plasma, the temperature of the plasma during transportation is D degrees Celsius, and D degrees Celsius is greater than the specified temperature of 10 degrees Celsius for transporting liquid plasma. At this time, an alarm is given to the driver to prompt that the transported blood product may deteriorate due to excessive temperature. When the top cover of the blood bag containing liquid plasma is opened during transportation, an alarm is given to the driver to prompt that the transported blood product has been illegally opened and may be contaminated. When the expected transportation time (A + B + C) hours of the blood product during transportation exceeds the specified 3 hours for liquid plasma, an alarm is given to the driver to prompt the driver to accelerate in time or change to a shorter route. When the driver enters this route again, an alarm is given to the driver to prompt that this route may cause the transportation time to exceed the specified time, and the driver needs to accelerate or change the route. When the initial weight of the blood bag and the blood product inside is gN, and the weight decreases from gN during transportation and lasts for Hs, an alarm is given to the driver to prompt the driver to check the blood bag. When the blood bag is opened and the alarm device gives an alarm to the driver, within Ts, the blood product in the blood bag has not been processed. At this time, an alarm is given to the driver again to prompt the driver again. At the same time, when the driver stacks several different blood products such as platelets and plasma together, an alarm is given to the driver to prompt the driver to place platelets and plasma in separate areas. The alarm unit 3 can also give an alarm to the driver in advance when the transported blood product slightly exceeds the specified temperature. For example, when transporting plasma, if the plasma temperature is 11 degrees Celsius, based on past experience, when the plasma temperature exceeds the specified temperature by 1 degree, its shelf life is shortened by F hours. At this time, the expected time is (A + B + C + F) hours.

[0033] The refrigeration unit 1, including a thermoelectric cooler, receives the type information and temperature information. When the temperature of the blood product exceeds the specified temperature of this type of blood product, the blood product is cooled by the thermoelectric cooler until the temperature of the blood product drops to the specified temperature.

[0034] For example: When the blood product is platelets, the specified temperature is 22 degrees Celsius. At this time, the temperature of the platelets in a certain blood bag is E degrees Celsius, and E is greater than 22 degrees Celsius. At this time, the thermoelectric cooler cools the platelets in this blood bag until the temperature of the platelets is lower than 22 degrees Celsius.
