Description

Technical Field

[0001] This utility model relates to the field of drug dispensing technology, specifically to a positron emission tomography (PET) automatic drug dispensing device. Background Technology

[0002] Positron emission tomography (PET) drugs, also known as PET imaging agents, are liquid drugs labeled with radioactive nuclides that emit positrons. Radiopharmaceuticals used in clinical PET imaging are therefore also called PET drugs or PET imaging agents. They are a relatively new class of radiopharmaceuticals containing short-half-lived positron-emitting nuclides, used in disease diagnosis, efficacy evaluation, and organ function research. Because positron-emitting nuclides generally have very short half-lives, a large dose can be administered to the patient at once, achieving a high count rate and obtaining clear images in a short time, while the radiation dose received by the patient is relatively small. In many dynamic studies, repeated administration and imaging are possible without long waiting times.

[0003] Most existing positron emission tomography (PET) automated drug dispensing devices rely on manual dispensing, which results in uneven filling of the drug solution during dispensing, making it impossible to accurately and uniformly measure the amount of drug solution in the container. This leads to low dispensing efficiency and poor dispensing results. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing positron emission tomography (PET) automated drug dispensing devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a positron emission tomography (PET) automatic drug dispensing device. During use, the container rack is placed in the first limiting groove, and the baffle is pulled. The drug container falls onto the first conveyor belt under gravity. The first drive motor drives the cam and the fourth bevel gear to rotate, which in turn drives the first conveyor belt to move, conveying the drug container into the arc-shaped groove of the first grooved wheel. Simultaneously, the lever, in conjunction with the through groove, drives the first grooved wheel to rotate intermittently. The first gear drives the acceleration gear to rotate, and through the cooperation of the first and second bevel gears, drives the impeller to rotate, drawing the drug liquid from the container to... Inside the liquid outlet pipe, since both the liquid outlet pipe and the liquid inlet pipe have a certain length, there is a certain time difference between the extraction action and the liquid discharge action. When the rotation stops, the liquid container is transported along the arc-shaped guide rail to the bottom of the liquid outlet pipe. After traveling, the liquid flows down from the vertical section of the liquid outlet pipe into the liquid container. When the liquid container is transported to the discharge port, the second drive motor drives the second conveyor belt to transport the liquid container out. This solves the problem that most existing positron emission tomography (PET) automatic drug dispensing devices are manually dispensing, and the liquid filling is uneven during dispensing, making it impossible to accurately and uniformly measure the amount of liquid in the container.

The second bevel gear 40 meshes with the first bevel gear 38. An inlet pipe 42 and an outlet pipe 41 are fixedly connected to both ends of the water pump 35, respectively. A medicine tank 13 is fixedly connected to the top of the base 1. The input end of the inlet pipe 42 is located inside the medicine tank 13.

[0025] The first conveying assembly includes a second fixed frame 2. A first conveying roller 19 and a second conveying roller 20 are movably connected to both ends of the second fixed frame 2. A first conveyor belt 21 is provided between the first conveying roller 19 and the second conveying roller 20.

[0027] The second fixed frame 2 has a first limiting groove 22 at one end of its top. A container rack 6 is movably connected in the first limiting groove 22. A limiting block 44 is provided at the bottom of the outer side of the container rack 6. Multiple liquid medicine containers 43 are placed in the container rack 6. The second fixed frame 2 has a second limiting groove 23 at one end of its top. A baffle 9 is movably connected in the second limiting groove 23.

[0028] The second conveying assembly includes a third fixed frame 3, with a third conveying roller 24 and a fourth conveying roller 25 movably connected to both ends of the third fixed frame 3. A second conveyor belt 26 is provided between the third conveying roller 24 and the fourth conveying roller 25. A second drive motor 5 is fixedly connected to one side of the third fixed frame 3.

[0029] Specifically, the container rack 6 is placed in the first limiting groove 22, and the baffle 9 is pulled.

This solves the problem that most existing positron emission tomography (PET) automatic drug dispensing devices are manually dispensing, and the liquid filling is uneven during dispensing, making it impossible to accurately and uniformly measure the amount of liquid in the container. This results in low dispensing efficiency and poor dispensing effect.
