[0001] The invention relates to the technical field of radioactive drug administration protection devices, and in particular to a nuclear medicine radioactive drug administration radiation protection device. Background Art

[0002] Nuclear medicine radioactive drugs are increasingly playing a leading role in the treatment of diseases. However, nuclear medicine drugs are radioactive, so medical staff often need to wear lead clothing to protect themselves when administering drugs. Although lead clothing can provide certain protection, it still has a radiation effect on exposed parts. For example, when nuclear medicine uses iodine 131 to treat the thyroid gland, iodine 131 needs to be distributed to patients for drinking. The conventional method is that patients go to a specific nuclear medicine window to receive iodine 131 liquid. During this process, medical staff need to distribute iodine 131 liquid according to the patient's identity information, and they will inevitably be exposed to iodine 131 liquid radiation. Based on this type of problem, it is necessary to design a device that allows patients to automatically receive nuclear liquid medicine, thereby avoiding the radiation of nuclear drugs to medical staff and achieving the greatest nuclear radiation protection effect for medical staff. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.

[0033] When administering existing nuclear medicine radioactive drugs, medical personnel are often required to distribute the drugs on site. In order to reduce the radiation of the drugs, medical personnel often need to wear lead suits for protection throughout the process. However, the lead suits are heavy and the workload of medical personnel is large. At the same time, the parts of the medical personnel that are not covered by the lead suits are also easily damaged by nuclear radiation. Therefore, in order to solve the problem that medical personnel are in a nuclear radiation environment for a long time when distributing drugs, a protective device needs to be designed to reduce or avoid contact between medical personnel and nuclear drugs, thereby achieving a protective effect for medical personnel.

[0034] The main inventive point of the present invention is that by setting up a nuclear medicine radioactive drug administration radiation protection device, it can automatically identify the patient's identity information, automatically realize the supply of nuclear drugs, reduce the medical staff's participation in the drug administration process, thereby achieving the protection effect for medical staff.

[0035] refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 A nuclear medicine radioactive drug administration radiation protection device comprises a shell 1, wherein an upper space and a lower space are formed inside the shell 1 through a partition plate 18, wherein a controller 3 and a liquid discharge device are installed in the upper space, and a trash can 13 is installed in the lower space. The shell 1 is made of a material that can resist nuclear radiation, such as a common lead material, or a composite material containing lead. A collection device 2 is installed outside the shell 1 for identifying the patient's identity information. The liquid discharge device in the upper space comprises a liquid medicine storage tank 4, a liquid extraction pipe 5, a pump body 6 and a liquid discharge pipe 7, wherein the output end of the liquid discharge pipe 7 extends to the outside of the shell 1. During the liquid discharge process, the pump body 6 extracts liquid from the liquid medicine storage tank 4 through the liquid extraction pipe 5. The internal medicine liquid is then discharged through the discharge pipe 7 to realize the discharge action. Since the main invention point of the design of the present invention is to enable the patient to complete the medicine taking independently, the whole process of nuclear medicine administration does not require the participation of medical personnel, so as to protect the medical personnel. Therefore, the liquid discharge device is controlled by the controller 3 to discharge the liquid, that is, the controller 3 collects the identity information to be identified and compares it with the preset identity information. When the comparison passes, the controller 3 controls the pump body 6 of the liquid discharge device to discharge the nuclear medicine liquid. When the comparison fails, the controller 3 does not control the pump body 6 of the liquid discharge device to work, and the nuclear medicine liquid is not discharged at this time. In this way, the patient's medication work is completed independently through the drug delivery device, and the maximum protection for medical personnel is achieved.

[0036] It should be further explained that the collection device 2 can be as follows: Figure 3 As shown, there is a camera 201 capable of performing face recognition, or a card reader 202 capable of reading an ID card, but the acquisition device 2 is not limited to these two methods. It can also be a fingerprint recognition device or an iris recognition device, etc., wherein the pre-set identity information also includes the amount of medicine set by the medical staff according to the patient's physical condition. When the controller 3 reads the identity recognition information, the amount of medicine required by the current patient is obtained synchronously, and the controller 3 controls the operation of the liquid discharge device according to the set amount of medicine.

[0037] For further reference, Figure 8 A flow sensor 8 is also provided on the discharge pipe 7 for monitoring the discharge amount of the liquid medicine of the liquid outlet device and transmitting the discharge amount signal of the liquid medicine to the controller 3. When the controller 3 determines that the discharge amount of the liquid medicine reaches the set medicine drinking amount, the pump body 6 is controlled to stop running.

[0038] For further reference, Figure 8 In order to ensure that the liquid medicine is discharged with a cup body 10 in the output direction of the discharge pipe 7 to prevent the liquid medicine from spilling, the output end of the discharge pipe 7 has a placement table 9 on which the cup body 10 can be stably placed. A groove 901 can be provided on the placement table 9 to ensure that the cup is stably placed. A pressure sensor 902 is provided inside the groove 901 of the placement table 9. The pressure sensor 902 is connected to the controller 3 for providing a pressure signal to the controller 3. When the cup body 10 is placed on the placement table 9, the controller 3 can receive the signal of the pressure sensor 902 and control the action of the liquid discharge device. When the controller 3 does not receive the pressure signal, the controller 3 does not control the action of the liquid discharge device.

[0039] For further reference, Figure 2 , Figure 4 , Figure 5 and Figure 6 In order to allow medical personnel to replace the insufficient liquid medicine in the liquid medicine storage tank 4, the liquid medicine storage tank 4 can be isolated from the medical personnel when it is opened for operation and installation, a transparent opening and closing door 11 is provided on the rear wall of the upper space of the shell 1. The transparent opening and closing door 11 can be made of leaded glass material. Two rubber gloves 12 are provided on the transparent opening and closing door 11. After the medical personnel open the transparent opening and closing door 11, they place the liquid medicine storage tank 4 in the upper space, close the transparent opening and closing door 11, and then Insert both arms into the rubber gloves 12, open the medicine cover of the medicine liquid storage tank 4, and then connect the medicine liquid storage tank 4 with the cover body 15 on the liquid extraction tube 5 to replace the medicine liquid storage tank 4. The rubber gloves 12 are made of lead-containing or radiation-resistant materials to isolate the medicine liquid storage tank 4 from the medical staff during the replacement process. After the medicine cover on the medicine liquid storage tank 4 is unscrewed, the medicine cover can be thrown into the trash can 13 in the lower space by opening the openable and closable door panel on the partition plate 18.

[0040] For further reference, Fig. 9 After the patient takes away the cup containing the radioactive liquid medicine, the pressure signal of the pressure sensor 902 disappears. Figure 3 and Figure 4 The controller 3 controls the telescopic rod 14 to move the trash can 13 out of the shell 1, so that the patient can put the radioactive cup into the trash can 13 after drinking the medicine. The controller 3 also has a clock module 301 inside. When the trash can 13 is opened for a certain period of time, the controller 3 controls the telescopic rod 14 to move the trash can 13 back into the shell 1. The certain period of time is required to meet the time used by the patient to drink water.

[0041] For further reference, Fig.10 The medicine inside the medicine storage tank 4 needs to be monitored to provide a timely reminder when the medicine is insufficient. A liquid level sensor 501 is also provided on the cover 15 on the liquid extraction tube 5 for monitoring the remaining amount of medicine inside the medicine storage tank 4. When the controller 3 determines that the remaining amount of medicine is insufficient by receiving the signal from the liquid level sensor 501, the alarm device 16 is controlled to work to remind the patient in time. Of course, the controller 3 can also communicate with an external terminal to remind medical staff in time. The alarm device 16 can be a speaker or a text prompt on the display screen 19.

[0042] Furthermore, in order to enable the patient to know the steps of the medication collection process, a display screen 19 is also required to be provided to provide prompts of the steps of the medication collection process during the medication collection process, and to provide a text prompt indicating insufficient medication liquid when the medication liquid is insufficient.

[0043] In summary, reference Fig.11 , the principle of the drug taking process of the present invention is described in detail. First, the controller 3 compares the identity information collected by the collection device 2 with the pre-set personnel information. If the comparison is unsuccessful, the pump body 6 is not controlled to discharge the liquid. If the comparison is successful, the amount of liquid medicine required by the patient with the current identified identity is synchronously obtained. The pressure sensor 902 determines whether the patient has placed the cup on the designated placement table 9 area. If it is determined that the cup has been placed, the controller 3 controls the pump body 6 to discharge the liquid. During the discharge process, the flow sensor 8 sends a signal to the controller 3. The controller 3 determines the current discharge volume of the liquid medicine according to the signal of the flow sensor 8. When the discharge volume of the liquid medicine reaches the set value, the discharge process is terminated. Therefore, in the process of administering nuclear drugs, the patient only needs to operate to take the medicine by himself, and there is no need for medical staff to be nearby. When replacing the liquid medicine storage tank 4, the medical staff can also operate through the rubber gloves 12 (made of material that shields nuclear radiation) to achieve radiation isolation and achieve maximum protection for medical staff.
