Problems solved by technology

[0006] The purpose of the present invention is to provide a system and method, which mainly solves the two problems of the prior art. One is not aware that the large amount of radiation received by the front-line packaging personnel day after day can be avoided, and the other is that the existing The so-called automatic dispensing system basically can only automatically extract the dispensing of a syringe. The degree of replacement for repeated extraction and detection is not high, and it cannot be replaced at all, or it can replace manual dispensing to a considerable extent. Original, no prior art inspiration

Embodiment 1

[0033] A mechanical device of an automatic dispensing system for radioactive drug liquid, characterized in that it includes a tray moving device 1 , a needle cap device 2 , a needle tube device 3 , a liquid pumping device 4 , and a proximity switch 5 .

[0034] The tray moving device includes a first stepping motor 11 , a left limit switch 12 , a first ball screw 13 , a right limit switch 14 , a tray frame 15 , and a syringe holder 16 . The tray moving device is responsible for moving the tray rack containing the syringes left and right, for example, it is on the right side at the beginning, and then moves to the left in turn, each time it moves, a syringe is dispensed, and after all is completed, the tray rack is moved to the right position, Such as the initial position, waiting for the operator to put it into the lead box.

[0035] The needle clamping cap device includes a first photoelectric sensor 21, a second stepping motor 22, a shaft coupling 23, a second ball screw 24,...

Embodiment 2

[0042] An automatic dispensing system for radioactive liquid medicine, comprising the aforementioned mechanical device, characterized in that it also includes a control cabinet group 7, a computer system 8, and a shielding device 9.

[0043] The control cabinet group has a power switch 71 and an emergency stop device 72; the shielding device at least shields radiation from two sides of the mechanical device.

[0044] Further, the packaging system also includes: the control cabinet group 7, the computer system 8, the shielding device and the mechanical device are connected through signal lines, communication lines and power lines; the emergency stop device can make the mechanical device stop all operations immediately; the shielding device Composed of lead plate, stainless steel, and lead glass, with at least one lead glass window.

[0045] The automatic dispensing system of radioactive drug solution is mainly composed of mechanical device, 2 control cabinets, computer host and...

Embodiment 3

[0047] A method for automatic dispensing of radioactive liquid medicine, which is implemented by using a previous automatic dispensing system for radioactive medicinal liquid, characterized in that it comprises the following steps: (1) putting the liquid medicine bottle to be repacked into a lead tank Among them, the lead can is fixed with a lead can fixing device. The liquid medicine bottle should be put into it without disturbing, and it has been effectively fixed. The liquid medicine bottle is placed upside down in it, and its centerline coincides with the centerline of the lead tank. Arrange the exhaust needle and insert one end into the liquid medicine bottle.

[0048] (2) Place 3-10 empty syringes on different syringe holders on the same tray frame, so that the tray frame matches the lead screw of the first ball screw. For example, if it is 5, pay attention to ensure that the position of the syringe meets the predetermined requirements, and you can use the marking line...

Description

technical field [0001] The invention relates to the technical field of dispensing radioactive medicinal liquid, in particular to an automatic dispensing system and method for dispensing radioactive medicinal liquid. Background technique [0002] With the rapid development of nuclear medicine in my country, with the widespread use of radiopharmaceuticals and the innovative research and development of new drugs, single photon emission computed tomography (Single Photon Emission Computed Tomography, SPECT), PET, PET / CT and other radiopharmaceuticals that can be used The variety and quantity are also increasing. The radiopharmaceuticals are marked first, and after passing the radiochemical purity test, they are manually subpackaged in a fume hood into the activity required by each patient for inspection. During the process, it is often difficult to operate with heavy gloves or radiation protection suits. Without protective gear, the total radiation dose received by the staff is ...
