Description

Technical Field

[0001] This utility model relates to a positive sample preparation pen with microtube implantation function, belonging to the field of positive sample preparation technology. Background Technology

[0002] Pharmaceutical packaging requires sealing testing technology, which necessitates the preparation of positive samples and the development of methodologies. The preparation of positive samples is a complex process involving the following steps:

[0003] 1. Hole making: Select a suitable location and use a needle with a certain aperture to make micro-holes in the sample bottle (bag);

[0004] 2. Implantation: Insert the microtube into a needle of a certain length, hold the microtube in place by hand, and insert it into the prepared microtube hole;

[0005] 3. Sealing: Apply UV adhesive to the hole location, and then use a UV lamp to cure the UV adhesive;

[0006] 4. Cutting: Use a ceramic knife to cut off any excess exposed microtubes.

[0007] The microtubes used in the preparation of materials are mostly made of glass, which is costly. The microtubes themselves are very thin, making them difficult to handle during sample implantation, and the tips are very thin and easily damaged. The entire preparation process is complex, difficult to operate, and inefficient. Utility Model Content

[0008] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a positive sample preparation pen with microtube implantation function for preparing positive samples for sealing tests, thereby reducing the difficulty of operation and improving the efficiency of positive sample preparation.

A foldable glue supply arm is provided on one side of the cylindrical body, which is hinged to the cylindrical body. The foldable glue supply arm has a hollow structure and is connected to the bottom of the glue reservoir through a glue supply tube. Several UV lamps are also installed at the bottom of the cylindrical body, and the UV lamps are electrically connected to a UV lamp switch. A microtubule cutter is also rotatably connected to the cylindrical body, and the microtubule cutter is used to cut off the excess exposed portion after implantation of the microtubule.

[0010] The technical solution of this utility model is to provide a positive sample preparation pen with microtube implantation function. The microtube hole is prepared by the implantation needle, the microtube is implanted into the sample by the tube bundler, UV glue is applied by the folded glue supply arm, the UV glue is cured by UV lamp irradiation, and finally the excess exposed microtube is cut off by the microtube cutter to complete the preparation of the positive sample.

[0011] Preferably, the tube bundler includes a tube bundle frame, with several elastic grippers arranged in a circumferential array at the bottom of the tube bundle frame.
