Full-automatic pipette tip box

Abstract

The invention belongs to the technical field of biomedical equipment, and particularly relates to a full-automatic pipette tip box. The full-automatic pipette tip box comprises a box body, a conveyingmechanism, a ratchet mechanism and a control mechanism. According to the invention, tips are vertically inserted into a storage disc, and storage grooves and spiral tracks respectively on the storagedisc and a guide disc correspond to each other, so that the tips can be scattered, and the problem that the sterilization quality does not reach the standard due to accumulation of the tips is avoided. The tips on the storage disc are guided by the guide disc to move along the spiral tracks and finally vertically fall down from an opening along a bearing table, so that the phenomenon of circlingis avoided, and the stable falling of the tips is ensured. An infrared sensor is used for sensing a human hand, and after a hand is sensed, a motor drives a swing rod to perform a reciprocating action, and a tip falls down, so that automatic falling of the tip is realized, and an experiment is facilitated.

Description

Technical field [0001] The invention belongs to the technical field of biomedical equipment, and specifically relates to a full-automatic pipetting gun tip box. Background technique [0002] The tip of the pipetting gun needs to be sterilized at high temperature before use to ensure that the tip is hygienic and sterile; and it needs to be sterilized at high temperature together with the tip box containing the tip during sterilization. Most of the existing pipetting When you need to use the tip of the gun tip box, you must first open the gun box cover and then take the tip. When doing experiments, your hands may be occupied, that is, hold the gun in one hand and the test tube or other items to be added in the other. It is extremely inconvenient to replace the tip of the pipette when it is necessary to free up a hand, open the gun box, and take out the tip of the pipette, which greatly hinders the experiment process, and frequent opening of the gun cover can easily contaminate the ...

Problems solved by technology

[0002] The tip of the pipette needs to be sterilized at high temperature before use to ensure the sanitation and sterility of the tip; and it needs to be sterilized together with the tip box containing the tip during sterilization. Most of the existing pipettes When the gun head box needs to use the gun head, the gun box cover must be opened first, and then the gun head is taken. When doing experiments, both hands may be occupied, that is, one hand holds the gun, and the other hand takes the test tube or other items to be added. It is very inconvenient to replace the tip of the pipette when using the pipette, and it is necessary to free up one hand to open the gun box and take out the tip, which greatly hinders the experimental process, and frequent opening of the gun cover is also very easy to pollute the tip of the pipette

[0003] In the prior art, although some pipette tip boxes solve the problem of frequent opening of the tip box, there is accumulation of tips, and the sterilization quality of the tips located in the center is poor during the high temperature sterilization process before use. There is no guarantee, and at the same time, the gun head falls in a rolling manner. Because the two ends of the gun head are of different sizes, there is a phenomenon that the gun head turns around one end, which affects the correct drop of the gun head.
