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.

Background technology
In the zoopery, often to use animal gavage pin, such as rat oral gavage pin etc., but because consumption is few, be difficult to buy in market ready-made applicable product, and researcher is with the homemade gavage pin of syringe needle, one of subject matter that runs into is the bad processing of syringe needle, mainly be that syringe needle is coarse, unsmooth, such consequence is meeting injury rats digestive tract in the gavage process, causes experimental rat injured so that dead.
Summary of the invention
Technical problem to be solved by this invention provides a kind of manufacture method of making the rat oral gavage pin by oneself, can solve the problem of injury experiment digestive tract in rats in the gavage process, the rat oral gavage pin syringe needle of making of the present invention is level and smooth, can the injury rats digestive tract in the 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 the rat oral gavage pin by oneself, and the method may further comprise the steps:
1) material is prepared: rustless steel marrow puncture needle and steel wire, gauge of wire are 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 in the insertion 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, suitably firmly press down gently with machining tool, and rotation, the syringe needle working position is occurred recessed;
4) continue firmly with machining tool, until the lower pressure side of syringe needle and rustless steel bone marrow aspiration syringe needle disconnect fully, take out the steel wire in the rustless steel marrow puncture needle, make self-control rat oral gavage pin.
The rustless steel marrow puncture needle of preparing in the step 1) is that diameter is 1.6mm, and length is the rustless steel bone marrow aspiration syringe needle of 55mm, and steel wire is that diameter is 1.4～1.6mm, and length is the steel wire of 80～120mm.
Using the machining tool place of pressing down in the step 3) is 6mm apart from the distance of needle tip.
Machining tool in step 3) and the 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 the injury rats digestive tract in the gavage process, and easy to operation.
