The driving wheel 1322 may be provided with a rubber layer on its exterior to increase the ability of driving the tray 140 to move forward and backward.

[0048] Figure 5 The structure of the medicine tray 140 is shown. The medicine tray 140 is provided with a plurality of grooves or countersunk holes 141 for accommodating the bottom of the bottled contrast agent. The diameter of the groove 141 is slightly smaller than the diameter of the bottom of the bottled contrast agent. The figure shows 20 grooves 141 that can accommodate 20 bottles of contrast agent. It should be noted that the number of the grooves 141 is not limited to 20.

[0049] The tray 140 is provided with limit posts 151 on both sides of the rear end to limit the forward movement of the medicine tray; the limit posts 151 are provided with limit sensors such as micro motion sensors ( Figure 5 (not shown) 1511 is used to output a signal for cutting off the power supply of the driving motor 1315 of the active driving member 131 when the limiting column 151 moves forward with the medicine tray 140 and touches the rear end of the pressure plate 150.

[0050] The pressure plate 150 is adjacent to but not in contact with the medicine tray 140; the pressure plate 150 is located above both sides of the medicine tray 140, and its length is less than the length of the medicine tray, preferably less than half the length of the medicine tray 140, so that most of the bottled contrast agents placed on the medicine tray 140 can be smoothly moved to the outside of the medicine unit, making it convenient for medical staff to take out or use the medicine.

[0051] Figure 6a and Figure 6b The scene shows that the medicine tray 140 of the present invention is filled with bottled contrast agent 500 and that the medicine tray 140 moves forward and some of the bottled contrast agent 500 is taken out.

[0052] like Figure 6a As shown, the medicine tray 140 is filled with 20 bottles of medicine 500, which are heated to a standard use temperature such as 37°C in the medicine unit for use by patients undergoing TC examinations.

[0053] like Figure 6b As shown. Whenever a patient needs to use medicine 500, the medical staff opens the unit door 110, starts the drive assembly 130 to rotate, and drives the tray 140 to move forward; when the limit column 151 on the tray 140 touches the rear end of the pressure plate 150, the tray 140 is limited to move forward, and the limit sensor on the limit column 151, such as the micro-motion sensor 1511, stops the drive assembly 130 from transmitting, so that most of the tray moves outside the medicine unit 100, so that the medical staff can take the required medicine 500 (the figure shows that 8 bottles of medicine 500 have been taken away). Then, the tray 140 is pushed back into the medicine unit 100 and the unit door 110 is closed.

[0054] The first medicine unit door 110 is provided with a door opening detector (not shown) 114, which can be a micro switch disposed between the back of the first medicine unit door 110 and the medicine tray 140, and is used to start the motor 1315 of the drive assembly to operate. For example, the door opening detector 114 is installed at the back of a medicine unit door 110 or at the front end of the medicine tray 140.

[0055] The power source E is connected to the motor 1315 via the door opening detector 114 and the limit sensor 1511 connected in series. The two contacts of the door opening detector 114 are normally open contacts, and the two contacts of the limit sensor 1511 are normally closed contacts. Fig. 9 When the first medicine unit door 110 is opened, the two contacts of the door opening detector 114 are connected, and the power source E is connected to the two motors 1315 via the door opening detector 114 and the limit sensor 1511, and the motors rotate. When the limit sensor 1511 touches the rear edge of the pressure plate 150, the two contacts of the limit sensor 1511 are disconnected, and the two motors 1315 are powered off and stop rotating.

[0056] The first medicine unit display 112 and the second medicine unit display 212 can display related information in a linked manner. When the first medicine unit display 112 displays "primary", the second medicine display 213 displays "standby" to prompt medical personnel to use the medicine in the first medicine unit; when the first medicine unit display 112 displays "standby", the second medicine display displays "primary" to prompt medical personnel to use the medicine in the second medicine unit.

[0057] Figure 10a-Figure 10c The synchronous switching circuit for switching the primary and standby display of the first and second medicine units is shown. One input end of the first medicine unit button 113 is connected to the positive pole of the power supply Ec, the other input end is grounded, and the two output ends are connected and connected to one input end of the same or gate A1; one input end of the second medicine unit button 213 is connected to the positive pole of the power supply Ec, the other input end is grounded, and the two output ends are connected and connected to the other input end of the same or gate A1; one end of the second medicine unit display or indicator 212 is connected to one end of the same or gate A1, and the other end is grounded; one end of the first medicine unit display or indicator 212 is connected to the output end of the inverter F1, and the other end is grounded; the inverter F1 is connected between the same or gate A1 and the indicator 212; the negative pole of the power supply Ec is grounded.
