Blood irradiation devices are commonly used to address transfusion-related graft versus host disease. The device is generally provided with a radiation generator, a shielding cavity, a rotary table, a high-voltage generator, an industrial personal computer and a shell. At present, a door of a shielding cavity of the existing blood irradiation equipment is generally opened at the side surface of the shielding cavity, a medical staff generally puts a blood bag to be irradiated into a cup body, then the cup body is horizontally pushed into the shielding cavity, and after the door of the shielding cavity is closed, a ray generator, a rotary table positioned below the cup body and a high-voltage generator are started to rotate and irradiate the blood bag in the cup body.
It should be noted that, when the cup body with the blood bag to be irradiated is placed at the correct position on the turntable in the shielding cavity, the irradiation effect of the blood bag is poor or the due irradiation effect cannot be achieved once the placement position of the cup body is deviated, but the medical staff is unaware, and the medical staff is likely to use the blood with poor or the due irradiation effect as the blood with good or up to standard irradiation effect by mistake, thereby causing danger. Only when the cup body is positioned at the correct position in the shielding cavity, the blood bag in the cup body can be ensured to be completely within the irradiation range, the irradiated blood bag can be ensured to reach the accumulated dose required to be irradiated, the uniformity of the blood bag radiation and the like, and the irradiated blood bag can be ensured to reach the expected irradiation effect, so that the irradiation quality of the blood bag can be ensured, and the blood bag can be used with confidence.
Based on the above-mentioned problem of determining whether the cup body placement position in the shielding cavity is correct, the current conventional solution is to install the electronic component for detecting the cup body placement position in the shielding body, but the service life of the electronic component is greatly reduced due to the rays generated in the shielding cavity in the irradiation process, when the electronic component will fail, the electronic component is unreliable to use; and when the electronic components are malfunctioning, medical personnel are unknown, and the blood with poor irradiation effect due to the wrong placement position of the cup body is likely to be used as the blood with good irradiation effect, so that danger is caused.

The upper surface of each of the delivery ends is connected with a pressing piece 11 which is arranged in an upward delivery way, and the bottom surface of each connecting rod 12 is connected with the first elastic piece 21. When the cup 600 is pressed onto each pressing member 11, the pressing portion 31 moves the protruding portion 32 downward to the first position. The structure is more accurate in arrangement, higher in reliability and material-saving.
In a third alternative embodiment, the load bearing mechanism 10 may also include at least two pressing members 11, but the bottoms of each two pressing members 11 are connected by a connecting rod 12, the top surface of the pressing portion 31 is connected to the center of mass of the connecting rod 12, the bottom surface of each connecting rod 12 is connected to at least two first elastic members 21, and the two first elastic members 21 are respectively disposed on two sides of the center of mass of the connecting rod 12.

In addition to the second and third embodiments, a preferred embodiment is that the connecting rod 12 may be provided with reinforcing ribs 13 along its extension direction to strengthen its load-bearing strength. In another preferred embodiment, as shown in fig. 2 and 13, the bearing mechanism 10 may further include a top plate 301, or the turntable 300 may include the top plate 301, and the top plate 301 may be provided with a longitudinal groove 3011 corresponding to each pressing member 11, so that the pressing member 11 may be exposed from the surface of the top plate 301 through the longitudinal groove 3011, and thus, the cup 600 may be directly contacted to the pressing member 11 of the bearing mechanism 10, thereby improving the response sensitivity, further enhancing the structural reliability, and improving the accuracy of the determination result.
Further, the positioning indication device 100 provided in the embodiment of the present application may further include an amplifying mechanism 40 for amplifying the distance signal of the up-down movement of the extension 32, so as to present more obvious prompt information to the user. The amplifying mechanism 40 is in driving connection with the extension 32, and the aforementioned moving part may be provided on the amplifying mechanism 40.
Regarding the aforementioned amplifying mechanism 40, the present application provides various preferred embodiments, and the first preferred embodiment is that, as shown in fig. 1 to 6, the amplifying mechanism 40 may include a first rotary fixing bracket 42 and a first rotary rod 41, the first rotary rod 41 is divided into two parts, namely, a first sub rod 411 and a second sub rod 412, the end of the first sub rod 411 is in contact with the aforementioned protruding portion 32 and is in driving connection, the end of the second sub rod 412 is the aforementioned moving portion or has the aforementioned moving portion, the moving portion is disposed towards the aforementioned observation prompting portion 50, the change of the up-down movement of the moving portion determines whether the cup 600 is placed on the correct position of the bearing mechanism 10, the connection portion of the first sub rod 411 and the second sub rod 412 is provided with a first connection through hole, the first connection through the first rotary shaft of the aforementioned first rotary fixing bracket 42 makes the two parts rotate up and down, preferably the length of the second sub rod 412 is longer than the length of the first sub rod 411, thereby achieving the effect of amplifying signal, and as a preferred scheme, the end of the second sub rod 412 is disposed as different colors of the observation prompting portion 50. When the cup 600 is placed on the right position of the bearing mechanism 10, the extending part 32 reaches the first position, the extending part 32 drives the first sub-rod 411 to rotate downwards, the first sub-rod 411 drives the second sub-rod 412 to rotate upwards, so that the moving part of the cup moves to the visual state of the observation prompting part 50, and a medical staff can see the moving part in the observation prompting part 50 to obtain a signal that the cup 600 is placed on the right position of the bearing mechanism 10; conversely, when the cup 600 is not placed on the correct position of the weight-bearing mechanism 10, the protruding portion 32 is in the second position, and the moving portion of the second lever 412 is in the invisible state of the observation presenting portion 50, so that the medical staff cannot see the moving portion at the observation presenting portion 50, and a signal is obtained that the cup 600 is not placed on the correct position of the weight-bearing mechanism 10. Because the up-and-down movement distance signals of the bearing part 31 and the extending part 32 which are generally in direct action connection with the bearing mechanism 10 are relatively small, the amplifying mechanism directly and effectively plays a role in amplifying the up-and-down movement distance signals of the extending part 32 by utilizing the lever principle, so that the prompt information presented to a user is more obvious.
Further, the bottom surface of the second branch 412 may be correspondingly provided with a second elastic member 22 that stretches up and down to help rebound up and down, and the bottom surface of the second branch 412 contacts with or is fixedly connected to the top surface of the second elastic member 22. Still further, the observation and prompting portion 50 may be disposed at a distance from the end of the second lever 412, and the surface of the observation and prompting portion 50 facing the second lever 412 may be a cambered surface, and the radian thereof may be the same as the radian of the rotation surface of the second lever 412. Thus, the second branch 412 does not contact and rub with the inner surface of the observation and prompting part 50, and the service life of the mechanism is prolonged.
Preferably, when the space between the observation indicating part 50 and the load bearing mechanism 10 is sufficiently large, the extending direction of the extending part 32 is optionally the same as the extending direction of the first rotating rod 41, and the extending end of the extending part 32 is directly arranged towards the observation indicating part 50, as shown in fig. 1 to 6, the arrangement is simpler than the other arrangement, and the extending part 32 extends from the gap between the two connecting rods 12, so that the up-and-down movement work of the connecting rods 12 is not affected, and the amplifying mechanism is not affected; when the space between the observation prompt part 50 and the bearing mechanism 10 is limited and not large enough, as shown in fig. 7 to 12, the extending direction of the extending part 32 and the extending direction of the first rotating rod 41 may be set to form an included angle, the extending end of the extending part 32 may extend from the side, then the first sub rod 411 of the first rotating rod 41 forms an included angle and is in driving connection with the first sub rod, so as to save the occupied space in the direction between the observation prompt part 50 and the bearing mechanism 10, but the extending end of the extending part 32 extends from the side, so that the highest upward moving point of the first sub rod 411 of the first rotating rod 41 is required to be ensured to be lower than the maximum downward moving position of the connecting rod 12, so as to ensure that the two parts do not affect each other, and the two parts can work normally. Preferably, to better achieve this, the first end 4111 of the first rotary lever 41 may be configured in an upward folded configuration to further lower the highest upward displacement point of the first split lever 411.
