Problems solved by technology

An important reason is that the micro-particles are very light, and the powder cannot enter the mold only by its own weight; in addition, the diameter of the pressing needles used as the upper and lower molds is small, and if the shaft holes of the mold are slightly out of alignment, the mold needles will break.

Embodiment 1

[0048] Embodiment 1 The structure of the automatic microtablet production equipment according to the present invention

[0049] The structure of the automatic mini-tablet production equipment of the present invention is as follows: figure 1 As shown, it consists of a feeding port assembly 1, a frame 2, an electromagnetic vibrator 3, a floating module 4, a pressing drive mechanism 5, a feeding port assembly 6, an electromagnetic tractor 7 and a control unit 8. Among them, the feeding port assembly 1 is composed of a handle 11, a feeding port cover 12, a feeding pipe 13, and a feeding pipe support plate 14, wherein the feeding pipe 13 is fixed on the feeding pipe supporting plate 14 by threads, and its upper end is The feeding port is isolated from the outside through the feeding port cover 12 when the powder is not added. The feeding port cover 12 normally closes the nozzle of the feeding pipe 13, and is only opened when it is necessary to add medicinal powder at the beginning...

Embodiment 2

[0064] The tablet pressing steps of the automatic mini tablet production equipment of the present invention are as follows:

[0065] 1. Turn on the switch of the automatic micro-tablet production equipment. At this time, the initial state of the system is: the electromagnetic vibrator 3 is energized to generate suction, so that the floating module 4 is sucked and fixed on the bracket; 432 is pulled back to the bottom of the feeding port assembly 1, that is, the powder adding position; the two pressing blocks 54 on the pressing connecting rod 55 are in an empty state in the middle, and are separated from the upper needle assembly 44 and the lower needle assembly 45.

[0066] Open the feeding port cover 12, add an appropriate amount of medicinal powder into the feeding funnel 432, and close the feeding port cover 12 after adding powder.

[0067] 3. Start the automatic operation switch, and the system starts to enter the automatic pressing process.

[0068] 4. The electromagneti...

Abstract

The invention discloses a production equipment capable of automatically processing micro-tablets, its use method and application. The device can be applied to the production of micro-tablets implanted in the body used in medical radiation therapy, and can also be used to manufacture special-purpose micro-pressed particles. The use of this equipment to produce radioactive cylindrical tablets can greatly reduce the chance of operators being exposed to radioactivity. At the same time, the miniature and compact body can also be placed on the medical site to meet the requirements of immediate processing of such tablets and cannot be stored. At the same time, the micro-tablets obtained through automated production have the advantages of uniform particle size, controllable size, and adjustable density, which can realize precise control of the radiation dose in the tablet, so that the sustained release time of the radioactive tablet can be precisely set.

Description

technical field [0001] The invention belongs to the field of automated machinery, and in particular relates to an automatic miniature tablet production equipment and a method and application for automatic tablet processing. Background technique [0002] Brachytherapy is a type of cancer radiation therapy in which the radiation source is directly implanted into the body, and the radiation therapy is performed by approaching the cancer lesion at a short distance. This method can locally increase the radiation dose while making the radiation range very small, thereby reducing the radiation to the patient's normal tissues and organs, and is a relatively advanced treatment method at present. This method requires the use of a soluble particle as the carrier of the radioactive source, the radioactive microtablet. Since such tablets can only be synthesized before treatment, the current methods all adopt the mode of manual instant pressing. The formed tablets are limited by the tech...
