Abstract
The invention provides a microorganism scriber, aiming to solve the problems such as secondary pollution caused by sterilization in repeated use of scribers in the prior art, inaccuracy in sample scribing and even culture medium scarification caused by metal structures of the scribers and incapability of achieving automatic scribing. The microorganism scriber comprises a matching end, a rigid connection section, a positioning block, a flexible connection section and a scribing contact end from top to bottom in the vertical direction. The matching end is positioned at the top end of the scriber and is matched with an external mechanical structure. The bottom surface of the matching end is connected with the top surface of the positioning block through the rigid connection section. The positioning block made of a rigid material is of a big-end-up trapezoid structure or a rectangular structure. The bottom surface of the positioning block is connected with the scribing contact end through the flexible connection section. The scribing contact end is of a flexible structure. The microorganism scriber has the advantages that better bacterial isolation effect is achieved, higher scribing efficiency is guaranteed, the problem of biologic cross contamination is solved, bacterial contamination is effectively prevented, and culture medium scarification is avoided.
Description
Technical field
The present invention relates to a kind of scriber, special is a kind of microorganism scriber.
Background technology
Scriber is very important apparatus in microbial inoculant, cultivation, separation and detection.At present, the scriber that microbial inoculant, cultivation, separation and detection are used is the metallic weapon that platinum material is made.Laboratory technician is manual operation, in experimentation, is rule on substratum by the hand-held scriber of laboratory technician.When artificial hand-held metal platinum scriber carries out experimental implementation, be very easy to substratum to scratch, and cause the erroneous judgement of experimental result.Moreover, when operating, amber gold scriber in use needs to reuse, therefore, after finishing using, need secondary use again after sterilization, therefore at every turn, if sterilization is not thorough, also can causes the repeated contamination of biological sample, have a strong impact on experimental result.Generally speaking, the metal platinum scriber of prior art also exists to reuse needs sterilization easily to cause secondary pollution, metal construction easily to cause the inaccurate problem of even scratching substratum of sample line, and this kind of scriber cannot realize automatization line.
Summary of the invention
Inaccurately even scratch substratum for reusing of solving that prior art scriber exists needs sterilization easily to cause secondary pollution, metal construction easily to cause sample to rule, cannot realize the problems such as automatization line, the present invention proposes a kind of microorganism scriber.
Microorganism scriber of the present invention, from top to bottom vertical direction comprises abutting end successively, the section of being rigidly connected, preset pieces, the section of flexibly connecting and line contact jaw, and described abutting end is positioned at the top of scriber and matches with external physical construction; The bottom surface of described abutting end is connected by the section of being rigidly connected with the end face of preset pieces; Described preset pieces is a up big and down small trapezoidal or rectangle structure and is rigid, and the underrun section of flexibly connecting of described preset pieces is connected with contact jaw of ruling, and described line contact jaw is also flexible structure.
Further, described mechanical mechanism is the crawl arm or the fixture that have blessing power, described abutting end be by bare terminal end and its one side for perpendicular to horizontal plane directed face all the other be sphere or cambered surface, described crawl arm or fixture and coordinating of mutually being clamped by bare terminal end.
Further, described physical construction is have the cylinder end of impact force and be right cylinder, square body or centrum, described abutting end for being knocked end and arranging groove or elongated hole, described cylinder end and groove or elongated hole shrink-fit.
Further, described line contact jaw is line ring or line ball.
Further, described line ball is ball, oval ball or hemisphere.
Further, described line ring or line ball are one or more.
Further, this scriber is polymer non-metallic material.
The Advantageous Effects of microorganism scriber of the present invention is: by the control realization of line ring or line ball to the control of content of molds, thus realize better bacteria distribution effect; Owing to adopting flexible line ring or line ball, and connection portion is also flexible structure, therefore, ensure that line accuracy rate is higher, make contacting more completely and can not destroying substratum of bacterial classification and substratum, flexible structure can adjust contact surface automatically according to the planeness of media surface; Substratum and scriber are polymer non-metallic material, be droppable single use running stores, the problem of biological crossed contamination is solved; The step eliminating scriber sterilization in line flow process is played, and production efficiency is accelerated, and mechanical service efficiency significantly improves, and effectively can prevent bacterial contamination.
