Abstract

The utility model relates to an inoculating needle with an intelligent temperature indication function. The inoculating needle comprises a rod body (1) which is made of a metal material, wherein a needle head part on the front end of the rod body (1) is formed by overlaying of a bimetallic strip, and the bimetallic strip (3) is formed by overlaying of a copper sheet and a steel sheet. The inoculating needle with the intelligent temperature indication function is simple in structure and easy to realize; the needle head part on the front end of the rod body (1) is formed by overlaying of the bimetallic strip; and the bimetallic strip is bent and arched at the temperature above 180 DEG C and restores to the straightness state at a normal temperature, thus the visual inoculating needle temperature indication is supplied for experimenters.

Description

A kind of inoculating needle of temperature intelligent indication
Technical field
The utility model belongs to the inoculating needle technical field, particularly relates to a kind of inoculating needle of temperature intelligent indication.
Background technology
Inoculating needle is a kind of experimental tool commonly used in biological experiment and the operation, but inoculate operation after when practical inoculating needle, mostly needing disinfection, inoculating needle need be heated to the high temperature more than 180 degrees centigrade when high temperature such as carrying out calcination is disinfected, inoculate operation again after waiting the inoculating needle cool to room temperature then, the bacterial classification of the too high easy scald inoculation of temperature if cooling time is too short, cooling time is oversize has then wasted a large amount of waiting time, has also increased the risk of living contaminants.In this process, the experimenter can't know what temperature inoculating needle has been cooled to, and is easy to because error in judgement influences carrying out smoothly of bacterial classification inoculation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of inoculating needle of temperature intelligent indication, barred body front end shank part forms so that bimetallic strip is stacked, bimetallic strip is higher than arched of 180 degrees centigrade of palintropes in temperature, become straightened condition when returning to normal temperature fully again, provide visual inoculating needle temperature prompt to the experimenter.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of inoculating needle of temperature intelligent indication is provided, comprises barred body, described barred body is made by metallic substance, and described barred body front end shank part forms so that bimetallic strip is stacked.
Described bimetallic strip is by copper sheet and steel disc is stacked forms.
Beneficial effect
The utility model is simple in structure, realize easily, barred body front end shank part forms so that bimetallic strip is stacked, bimetallic strip is higher than arched of 180 degrees centigrade of palintropes in temperature, become straightened condition when returning to normal temperature fully again, provide visual inoculating needle temperature prompt to the experimenter, thereby save the time that the experimenter waits for the inoculating needle cooling, avoid judging by accident disconnected simultaneously and cause high temperature to scald the problem of dead bacterial classification.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the inoculating needle of a kind of temperature intelligent indication comprises barred body 1, and described barred body 1 is made by metallic substance, and described barred body 1 front end shank 2 parts form so that bimetallic strip is stacked.
Described bimetallic strip is by copper sheet and steel disc is stacked forms.
Described barred body 1 front end shank 2 parts at inoculating needle form so that bimetallic strip is stacked, provide visual inoculating needle temperature prompt to the experimenter.In the experimentation, bimetallic strip temperature after the flame calcination is higher than arched of 180 degrees centigrade of palintropes, after the experimenter observes inoculating needle and becomes straightened condition again fully, can judge that inoculating needle has returned to normal temperature, just can carry out the bacterial classification inoculation operation.

Claims (2)

1. the inoculating needle of a temperature intelligent indication comprises barred body (1), it is characterized in that described barred body (1) is made by metallic substance, and described barred body (1) front end shank (2) part forms so that bimetallic strip is stacked.
2. the inoculating needle of a kind of temperature intelligent indication according to claim 1 is characterized in that, described bimetallic strip is by copper sheet and steel disc is stacked forms.
