Abstract
A home manufacturing method of a lavage needle for rats includes steps of 1), preparing materials including stainless steel bone marrow puncturing needles and steel wires; 2), threading the steel wires into the stainless steel bone marrow puncturing needles in a manner of exposing a little at the needle heads and the needle tips of the stainless steel bone marrow puncturing needles; 3) pressing the position of the needle heads 6-8mm distant from the needle tips on the stainless steel bone marrow puncturing needles by a processing tool with proper slight force, rotating to enable the processed portions of the needle heads to be recessed; and 4), continuously applying force by the processing tool until the pressed ends of the needle heads are completely separated from the stainless steel bone marrow puncturing needles, and taking out the steel wires in the stainless steel bone marrow puncturing needles to manufacture a home-manufactured lavage needle for the rats. The home manufacturing method of the lavage needle for rats can solve the problem about hurts on alimentary canal of the rats during lavage, the needle heads of the manufactured lavage needle for the rats are smooth, and the edges of the manufactured lavage needle are slightly bent. Besides, the lavage needle cannot hurt the alimentary canals of animals during lavage and is simple and convenient to operate.
Description
Technical field
The present invention relates to a kind of manufacture method of zoopery instrument, especially a kind of manufacture method of making rat oral gavage pin by oneself.
Background technology
In zoopery, often to use animal gavage pin, as rat oral gavage pin etc., but because consumption is few, be difficult on market, buy ready-made applicable product, and the homemade gavage pin of syringe needle for researcher, one of subject matter running into is the bad processing of syringe needle, be mainly that syringe needle is coarse, unsmooth, such consequence is meeting injury rats digestive tract in gavage process, causes experimental rat injured so that dead.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of manufacture method of making rat oral gavage pin by oneself, can solve the problem of injury experiment digestive tract in rats in gavage process, the rat oral gavage pin syringe needle of making of the present invention is level and smooth, can injury rats digestive tract in gavage process, easy to operation.
technical scheme
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of manufacture method of making rat oral gavage pin by oneself, and the method comprises the following steps:
1) material is prepared: rustless steel marrow puncture needle and steel wire, and gauge of wire is slightly less than the diameter of rustless steel marrow puncture needle, and the length of steel wire is greater than the length of rustless steel marrow puncture needle.According to the length of Rat Esophagus, should select length is the rustless steel marrow puncture needle of 55mm;
2) steel wire is run through and insert in rustless steel marrow puncture needle, steel wire respectively exposes a little at syringe needle and the backshank two ends of rustless steel marrow puncture needle;
3) at the syringe needle of rustless steel marrow puncture needle apart from needle tip 6～8mm place, with machining tool, suitably firmly press down gently, and rotation, syringe needle working position is occurred recessed;
4) with machining tool, continue firmly, until the lower pressure side of syringe needle and rustless steel bone marrow aspiration syringe needle disconnect completely, take out the steel wire in rustless steel marrow puncture needle, make self-control rat oral gavage pin.
The rustless steel marrow puncture needle of preparing in step 1) is that diameter is 1.6mm, the rustless steel marrow puncture needle that length is 55mm, steel wire be diameter for being more than or equal to 1.4mm, be less than 1.6mm, the steel wire that length is 80～120mm.
In step 3), using the machining tool place of pressing down is 6mm apart from the distance of needle tip.
Machining tool in step 3) and step 4) is electricians' plier.
The manufacture method of self-control rat oral gavage pin provided by the invention, can solve the problem of damage animal alimentary canal, and the rat oral gavage pin syringe needle of producing is level and smooth, and the slight inflection in edge, can injury rats digestive tract in gavage process, and easy to operation.
