In addition, the cooperation between the concave portion and the ball 1125 makes the storage box 900 more stable on the storage bit 112 and not easy to shake.
And a blood quality detection device 200 for detecting a layered interface condition of blood in the blood bag 001 and determining a blood quality from the layered interface condition of blood. And when the blood quality does not reach the standard, an alarm is given to remind human intervention.
The blood quality detection device 200 is configured as shown in fig. 6, and includes a detection box 210 with an opening on one side, a detection assembly and an analysis module arranged on the detection box 210, a clamping portion 1221 of a manipulator 122 is located inside the detection box 210, the clamping portion 1221 is used for clamping the storage box 900, the detection assembly is used for acquiring the layered interface condition of blood and sending the layered interface condition of blood to the analysis module, the analysis module includes a teaching model, and the analysis module analyzes and compares the received layered interface condition of blood with the teaching model and judges the quality of blood. The robot means that a robot 122 is provided in the refrigerator for storing blood to grasp the storage cassette 900 to move the storage cassette 900 into/out of the refrigerator. The blood quality measuring device 200 detects the blood quality in the different storage cassettes 900 by moving the hand 122 by mounting the detection cassette 210 on the hand 122.
The detection component has two forms, namely a spectrum identification sensor or a visual identification sensor.
First, the detection assembly adopts a spectrum recognition sensor, referring to fig. 7 and 8, a light source 220 and a spectrum recognition sensor 230 are respectively disposed on two opposite sidewalls of the detection box 210, the light source 220 is located at a side far away from the back plate 910, the spectrum recognition sensor 230 is located at a side close to the back plate 910 and directly faces the first transparent area 930, light emitted from the light source 220 penetrates through the layered interface area of the blood bag 001 and irradiates the spectrum recognition sensor 230 through the first transparent area 930, and the spectrum recognition sensor 230 acquires the layered interface spectrum of the blood. When the blood bag 001 is placed within the storage cassette 900, the layered interface region of the blood extends beyond the cassette 920 so that the spectral recognition sensor 230 successfully acquires the layered interface spectrum.
During detection, the light source 220 illuminates the layered interface region of the blood bag 001; the light emitted by the light source 220 penetrates through the layered interface region of the blood and irradiates the spectral recognition sensor 230 through the first transparent region 930, and the spectral recognition sensor 230 acquires the layered interface spectrum of the blood and uploads the layered interface spectrum data to the analysis module; and the analysis module compares the received layered interface spectrum with the teaching model for analysis and judges whether the blood quality reaches the standard.
In order to improve the spectrum quality of the layered interface, the distance between the light source 220 and the blood bag 001 and the distance between the spectrum recognition sensor 230 and the blood bag 001 are the same. Further, the distance between the two sidewalls of the detecting box 210 and the storing box 900 is 2-5cm, that is, the distance between the light source 220 and one side of the blood bag 001 and the distance between the spectrum recognition sensor 230 and the other side of the blood bag 001 are 2-5cm, respectively. The area of the spectrum recognition sensor 230 receiving the light source can cover 1/2 of the blood bag 001 to ensure that the layered interface spectrum can be recognized for blood bags 001 with different volumes and blood bags 001 placed at different angles within a certain range.
The cartridge 210 having only one side opened forms a relatively closed space, which can ensure the stability of the light source, and prevent recognition errors caused by position changes or external light source changes.
Secondly, the detection assembly adopts a visual recognition sensor, and referring to fig. 9 and 10, a visual recognition sensor 240 is arranged on a side wall of the detection box 210 far away from the back plate 910, and the visual recognition sensor 240 shoots a layered interface image of blood. When the blood bag 001 is placed within the storage cassette 900, the layered interface region of the blood extends beyond the cassette 920 so that the visual recognition sensor 240 successfully acquires the layered interface image.
During detection, the visual recognition sensor 240 on one side of the blood bag 001 shoots layered interface images and uploads the layered interface image data to the analysis module; and the analysis module compares the received layered interface image with the teaching model for analysis and judges whether the blood quality reaches the standard.
In order to improve the quality of the layered interface image, the distance between the two side walls of the cartridge 210 and the storage case 900 is 2-5cm, i.e., the distance between the visual recognition sensor 240 and one side of the blood bag 001 is 2-5 cm. The area of the blood bag shot by the visual recognition sensor 240 can cover 1/2 of the blood bag, so as to ensure that blood bags 001 with different volumes in a certain range and blood bags 001 placed at different angles can be shot by layered interface images.
The cartridge 210 having only one side opened forms a relatively closed space, which can ensure the stability of the light source and prevent an image photographing error caused by a position change or an external light source change.
The blood quality detection method may also use a pressure sensor in addition to the above-described spectrum recognition sensor and the above-described visual recognition sensor, and the principle of using a pressure sensor is that as the storage time of blood increases, the inside of blood is changed in quality, and the change in blood volume due to the quality change causes a change in pressure of the blood bag 001, and the blood quality is determined by detecting the change in pressure of the blood bag 001. Referring to fig. 11, pressure sensors 250 are respectively disposed on two side walls of the storage case 900, and when a blood bag 001 is placed in the storage case 900, the control unit controls the two pressure sensors 250 to be simultaneously activated to start detecting the pressure of the current blood bag 001; when the pressure sensor 250 detects that the pressure value is between 0 and 0.05Pa, the pressure sensor 250 uploads the current pressure value to the analysis module; in the storage process of blood, pressure sensor 250 detects the pressure of blood bag 001 in real time, and when the pressure value that pressure sensor 250 detected exceeded system's setting value, analysis module analyzed that blood quality did not reach standard this moment to send the analysis result to the control unit, the control unit sends the blood quality and reports to the police.
If the blood quality detection device 200 detects that the quality of the blood does not reach the standard, the analysis module sends an analysis result to the control unit, the control unit sends a blood quality alarm, and the output unit displays the information of the blood with the quality not reaching the standard and prompts a user to take out the blood with the quality not reaching the standard in time. If the blood with the quality not up to the standard can not be taken out in time, the control unit locks the blood with the quality not up to the standard and prohibits the blood from being taken out of the warehouse.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
