Abstract
The utility model discloses a threading needle, which is used for puncturing subcutaneous tissues, forming a temporary passage on the subcutaneous tissues to enable an infusion hose to penetrate through. The threading needle comprises a circular tube, wherein the front end face of the tube is in the shape of a needle. The method of using the threading needle includes that the threading needle is firstly punctured into subcutaneous tissues of a nape of an animal, and then the infusion hose is led into the tube of the threading needle and penetrates out from the other end face of the threading needle so that the infusion hose is led into a specific position of the subcutaneous tissues of the nape, and finally, the threading needle is taken out. The threading needle is simple in structure, and can lead the infusion hose to puncture from a neck front which is easy to be bitten by the animal through the subcutaneous tissues to the nape which is not easy to be bitten by the animal, thereby protecting the infusion hose.
Description
Technical field
The utility model discloses a kind of veterinary apparatus and instrument, be specifically related to a kind of animal infusion tube puncture and lead needle.
Background technology
In zoopery field and animal and veterinary field, carry out intravenous injection or blood sampling to animal through regular meeting.Take a blood sample for several times or waking state transfusion can select carotid artery of animal or jugular vein portion intubate to carry out usually as need.Common a kind of method is animal to be anaesthetized or whole body fixedly carries out intravenous injection or blood sampling, and the therapeutic effect to experimental result or animal all can have certain influence like this.Influence result of the test sometimes, and be difficult to carry out nor meet the requirement of animal welfare.And carrying out continuous intravenous injection or when treatment when blood sampling with clear-headed animal, animal is very easy to be baited the infusion tube of this position and influences the carrying out of transfusion or blood sampling.Infusion tube is fixed on the fur of animal with adhesive tape, outside this method infusion tube still is exposed to, can not guarantees not baited by animal, and adhesive tape fixing be not very firmly.
For this reason, method is that infusion tube is passed skin in the neck preferably, and infusion tube is passed from behind to nape portion, can guarantee that like this infusion tube do not baited by animal.But infusion tube self is too soft, can not pass skin.The experimenter is arranged with mosquito forceps break-through skin, infusion tube is introduced nape portion, but damage is too big like this.
Chinese patent " CN200920020614.0 " discloses a kind of " the fixing card of garter flexible pipe ", " is made up of pipe clamp fixture and the opening elasticity pipe clamp that is connected in the fixedly garter flexible pipe on the pipe clamp fixture." " the garter flexible pipe fixedly card cutting ferrule is in brothers finger, people ground, wrist very easily, flexible pipe can easily be connected in the fixing card of elastic opening, therefore very easy to use, efficient is very high; Fixedly flexible pipe is firm, can not produce the flexible pipe obscission ".This patent is primarily aimed at the mankind, when being used for animal, because of animal can struggle, baits, thereby thisly is exposed to outer fixed form and is not suitable for.
Chinese patent " CN 200720116124.1 " discloses a kind of " cluster transfusion device for animals ", and it comprises an adjustable fixedly connected band, syringe needle and flexible pipe binding can be fixed on the carcasses.This also is by being exposed to outer fixed form, can not stopping baiting of animal.
Thereby needing badly provides a kind of auxiliary device to make infusion tube pass through skin, can prevent to treat or laboratory animal oneself is baited the continuous blood sampling or the transfusion of pullling and can be used for clear-headed animal.
The utility model content
At above-mentioned defective, this utility model purpose provides a kind of protection infusion tube, can prevent to treat or laboratory animal oneself is baited the device of pullling.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of puncture and lead needle of the present utility model, described puncture and lead needle is used to the subcutaneous tissue that punctures, and forms occasional passage at subcutaneous tissue, allows infusion tube therefrom pass; Described puncture and lead needle comprises circular body, and the front end face of body is needle-like.
In a kind of preferred embodiment of the present utility model, described front end face forms angle theta by first inclined-plane and body axis, and angle theta is an acute angle.
In a kind of preferred embodiment of the present utility model, described front end face also has one second inclined-plane to form needle point with the first inclined-plane relative localization, and second inclined-plane and body axis form angle α.
In a kind of preferred embodiment of the present utility model, described front end face also has one the 3rd inclined-plane to form needle point with first inclined-plane, the second inclined-plane relative localization, and the 3rd inclined-plane and body axis form angle β.
In a kind of preferred embodiment of the present utility model, the angle of described angle α and angle β and less than 90 °.
In a kind of preferred embodiment of the present utility model, the material of described puncture and lead needle is rigid plastics or rustless steel.
In a kind of preferred embodiment of the present utility model, described body length is 30-200mm.
In a kind of preferred embodiment of the present utility model, described pipe diameter is 3-10mm.
Puncture and lead needle of the present utility model plays a role like this, earlier puncture and lead needle is punctured into the nape portion subcutaneous tissue of animal, infusion tube is introduced in the puncture and lead needle body again, pass from the other end of puncture and lead needle, thereby bring infusion tube into nape portion subcutaneous ad-hoc location, again puncture needle is taken out at last.Puncture and lead needle of the present utility model is simple in structure, can be with infusion tube from the throat portion that animal easily baits, and the subcutaneous tissue that passes animal is to the nape portion that animal can't bite, from protecting infusion tube.This utility model had both helped that the experimenter is simple and easy to introduce infusion tube nape portion apace, and very little to the damage of animal.
