Abstract

The invention discloses a method for detecting foreign matters in a disposable syringe. The method comprises the following steps that S1, the disposable syringe is cleaned and dried; S2, the disposable syringe dried in the step S1 is conveyed to a scratch detection area, and scratches on the inner wall and the outer wall are rapidly detected; S3, when qualified products detected in the step S2 are output to the scratch detection area, wall thickness information of different positions of the same disposable syringe is rapidly detected and collected through a plurality of contacts of a wall thickness detector, data information is transmitted to a background, and data differences are compared; S4, the disposable syringes detected to be qualified in the step S3 are continuously conveyed to pass through the detection channel of the light transmittance instrument; S5, the disposable syringe is filled with liquid medicine and sealed through plug pressing; and S6, finally, the disposable syringe is conveyed into intelligent foreign matter detection equipment for foreign matter detection. According to the method, surface scratches, wall thickness uniformity and light transmittance of the container are detected, good accuracy and high efficiency of subsequent foreign matter detection are guaranteed, and practicability is higher.

Description

technical field

[0001] The invention belongs to the technical field of foreign matter detection, and in particular relates to a method for detecting foreign matter inside a disposable syringe. Background technique

[0002] From the analysis of the pharmaceutical process, there are many links in which insoluble foreign matter is produced, and the types are also different, as shown. The main causes of insoluble foreign matter are: (1) impurity of raw and auxiliary materials introduces insoluble foreign matter pollution. (2) The non-dissolved foreign matter pollution introduced by the shedding of packaging materials during the packaging process. (3) The aging of manufacturing equipment or the unreasonable introduction of insoluble foreign matter pollution by process operation. (4) Production environment pollution, a large number of particles such as dust, soot, pollen, lumps, etc. suspended in the air;

[0003] Once the insoluble particles are injected into the human body, t...

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The invention provides a method for detecting foreign matter inside a disposable syringe, comprising the following steps;

[0029] S1. Transport the disposable syringe to be filled to the cleaning area through the transport rack to clean the inner and outer surfaces of the disposable syringe, and transport the inverted hanging book to the drying area for drying;

[0030] The disposable syringes dried in S2 and S1 are transported to the scratch detection area, and the s...
