Abstract
The utility model relates to a microinjection needle for shrimps and crabs. The existing disposable syringe has big injection volume, thick needle head and big puncture wound area, and can cause individual animals to die or decrease in activity after injection. The microinjection needle for shrimps and crabs comprises a disposable injection needle, a needle tube, a needle head and a needle point, wherein the needle head of the disposable injection needle is inserted into the needle tube from one end of the needle tube and is bonded and sealed with glue; the other end of the needle tube is contracted to form a conical needle head, the top of the needle head is the needle point, an injection orifice is formed on the needle point; and scale lines are graduated in the side wall of the needle tube. The microinjection needle for shrimps and crabs has the unique needle head and needle point, can enter the peritoneal subcutaneous tissue of shrimps and crabs with a small wound for puncture, can accurately dispose of accurate distribution of microliter level liquid, can perform quick injection with small wound puncture and micro volume on shrimps and crabs in the field or a culture workshop, and improves the injection efficiency and the survival rate of animals after injection.
Description
Technical field
This utility model relates to a kind of pumping needle, specifically is a seed shrimp Eriocheir sinensis animal micro-injection pin, can get into animal peritoneum subcutaneous tissue in little wound ground, carries out the injection of micro-volume.
Background technology
At present, known disposable syringe model specification generally uses milliliter level syringe.This toy of prawn Eriocheir sinensis is individual, and the volume injected of disposable syringe is big, and syringe needle is thick, and the puncture area is big, causes the death of animal individual or vigor to descend after the injection easily.The microinjection instrument that at present is used for the cell puncture uses the nanoscale capillary tube as the entry needle material, and puncture is little, and cell injury is little, and the upgrading that can realize receiving is injected.But whole microinjection device assembly is various, and equipment is accurate, costs an arm and a leg, and is difficult for carrying.Shrimp Eriocheir sinensis animal body surface is by carapace, realizes that there are many difficulties in micro-injection, also do not have economical and practically, and wound is little, controlled injection volume, simple portative micro-injection appearance.
Summary of the invention
The purpose of this utility model is exactly the deficiency to prior art, and a kind of micro-injection appearance is provided, and solves in the open air that prawn Eriocheir sinensis individuality punctures under the condition, existing technical problem when micro-injection and evacuation processes.
This utility model comprises injection needles and needle tubing, syringe needle, needle point.
The syringe needle of injection needles is inserted in the needle tubing by an end of needle tubing, is bonded and sealed through glue; The other end of needle tubing shrinks, and forms conical syringe needle, and the top of syringe needle is a needle point, and the needle point place is provided with injection orifice; The sidewall of needle tubing is carved with graduation mark.
The utlity model has unique syringe needle and needle point; Can puncture by little wound ground entering shrimp Eriocheir sinensis peritoneum subcutaneous tissue; And can realize accurately handling the accurate distribution of micro updating liquid; And can or culture the workshop in the open air and realize the little wound puncture of shrimp Eriocheir sinensis animal, the fast injection of micro-volume, improve the survival rate of injection efficiency with injection back animal.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
As shown in Figure 1, a seed shrimp Eriocheir sinensis animal micro-injection pin comprises injection needles 1 and needle tubing 2, syringe needle 3, needle point 4.
The syringe needle of injection needles 1 is inserted in the needle tubing 2 by an end of needle tubing 2, is bonded and sealed through glue; The other end of needle tubing 2 shrinks, and forms conical syringe needle 3, and the top of syringe needle 3 is a needle point 4, and needle point 4 places are provided with injection orifice; The sidewall of needle tubing 2 is carved with graduation mark.
