Description

Remote domestic animal continuous injector

This utility model relates to the domestic animal injection tool that a kind of veterinary of basic unit of confession uses, especially can be away from the remote domestic animal continuous injector of carcass operation.

For a long time, be in the backward state of using traditional Luer's syringe for animals aspect the injection tool for animals always, thus numerous rope programs such as " circle, catch " down, can only be followed to the injecting method of domestic animal, not only not only tired but also dirty, and efficient is low, dangerous.Though solved this problem, there is certain deficiency in the appearance of remote semi-automatic domestic animal filling gun (patent No. 86205455.9) specifically practicing in the process, thus influence and limited popularizing in the vast veterinary personnel of basic unit.Its main deficiency is: 1, function is complete, the manufacturing cost height, and the injection of domestic animal is not often needed its repertoire, shooting function of injection (occupying very high cost ratio) as syringe needle high-speed flight that animal (comprising the park wild animal) is carried out then can save concerning domestic animal fully, as remove this function, not only avoided waste but also the manufacturing cost on the function to descend significantly, thereby taken a firm foundation for popularizing.

2, when the colony immunization inocultation that is used for intensive domestic animal, pig farm for example, the bull pig is raised with circle, its range of activity is limited, under remote operated condition, have after the injection of pig finishes, can be basically as you werely carry out at once next pig injection make things convenient for chance, simultaneously, because of injected dose very little, syringe needle only needs to stop blink in the pig body, is therefore keeping the remote operated while, apace inserting needle and to pull out the interval that pin shortens between the double injection be the key link of raising the efficiency.Remote semi-automatic domestic animal filling gun owing to must there be one to reclaim syringe needle and the auxiliary movement that syringe needle is installed, obviously exists the not compact problem of injection joint rate between double injection, have influence on the further raising of work efficiency.

The purpose of this utility model provides a kind of injection tool that is specifically designed to domestic animal, the function that it not only has remote-controlled operation and injects continuously, and in colony's epidemic preventing working of intensive domestic animal, can remedy the deficiency of " remote semi-automatic domestic animal filling gun " effectively, simple in structure, low cost of manufacture is convenient to popularize in vast veterinary personnel of basic unit and cattle breeding industry simultaneously.

This utility model is made up of syringe needle anti-not (preventing that domestic animal is because of shaking off, escape the transverse curvature moment that syringe needle is formed in the injection process) device, continuous injecting apparatus two parts.

Syringe needle is anti-not to be installed by action bars head＜1 〉, action bars tail＜2, handle＜3, connect extension spring＜4, needle holder＜5, help and take off stage clip,＜6, telescopic head,＜7 〉, tight silk＜8 form.

Continuous injecting apparatus is by simple glass syringe＜9 〉, valve combination＜10, container＜11, have handle and a plate machine protect frame＜12, dosage adjusting screw(rod)＜13, small extension spring＜14, short catheter＜15, long catheter＜16 form.

The purpose of this utility model is achieved in that

Injection needle is installed in needle holder＜5〉on, the needle holder handle is inserted in action bars head＜1〉in the blind hole of front end, be set at action bars head＜1〉telescopic head＜7 of front end〉push down, can not freely come off, action bars head＜1〉with bar tail＜2 between by extension spring＜3 do and flexibly connect that (two rod end surface do not contact mutually, the middle gap greatly that keeps), action bars tail end has the handle clamping device of being made up of four fastening bolts and clamping plate, and by this clamping device with action bars tail＜2 and handle＜3 link together.Catheter＜16〉front end and needle holder＜5〉interlink (being tight fit) with the catheter joint at needle holder rear portion, the valve combination of rear end and continuous injecting apparatus＜10〉the fluid valve interlink, simple glass syringe＜9〉with valve combination＜10 interlink valve combination＜10 liquid flowing valve and container＜11 interlink.

Operator's left hand is held handle＜3 during injection〉by action bars syringe needle is thrust carcass, because action bars head＜1〉and bar tail＜2 between make of a stage clip and to flexibly connect, so the longitudinal thrust from handle can only be delivered on the syringe needle, and the cross force that action causes of shaking off owing to domestic animal can not be passed to action bars tail＜2 by syringe needle〉and handle＜3 on, thereby can not form bending moment to syringe needle, make syringe needle avoid by not Wan or not disconnected.Meanwhile, the right hand is held the plate machine can inject carcass to medicinal liquid by catheter, in valve combination＜10〉effect under, when holding trigger action continuously, medicinal liquid can continuously inject carcass.

When large bolus injection (as being used for the treatment of), because of needs long inject time, for fear of in the medicinal liquid injection process, because of domestic animal do successive significantly shake off the action syringe needle is extracted, action bars should break away from so that syringe needle (together with needle holder) rests on the carcass without restrictions from the pinhead handle seat after syringe needle thrusts carcass immediately, thereby obtains enough inject time.At this moment, because needle holder＜5〉and continuous injecting apparatus between only have thin catheter to do to flexibly connect, so the jump of domestic animal with shake off action no matter amplitude is much, do not influence the injection of medicinal liquid yet.

Be positioned at action bars head＜1〉helping of blind hole end take off stage clip, be to impel the rapid and needle holder handle release unit of action bars, moment before syringe needle is about to thrust domestic animal skin, the suffered resistance maximum of syringe needle, help spring removal＜6〉be compressed at utmost, thrust skin and help spring removal＜6 later on restore rapidly, its elastic force continues the needle holder handle to push ahead, thereby make the needle holder handle from action bars head＜1〉blind hole deviate from substantially, the left hand of the hand-held handle of operator returns a little to remove needle holder handle and action bars are broken away from fully.This has just caused and identical injection system and the effect of remote semi-automatic domestic animal filling gun.After injection finished, the same with remote semi-automatic domestic animal filling gun, syringe needle was retracted by catheter together with needle holder.

During as immunization inocultation; because injected dose is very little; required inject time is very short; Zhuan Zhi just can not protect syringe needle fully only according to the anti-of action bars; so use tight silk＜8〉the needle holder handle is fastened on the action bars; so that syringe needle can directly be advanced directly in fast pace ground on carcass, thereby obtains higher work efficiency in the drove body immunization inocultation process of being in.

Owing to taked such scheme, this utility model not only has the major function of remote semi-automatic domestic animal filling gun in heavy dose of medicine injection, and owing to can make syringe needle fast pace ground directly advance directly, so also have the original function that is fit to colony's immunization inocultation of intensive domestic animal more, in particular for various types of pig farms, comparable remote semi-automatic domestic animal filling gun plays a greater role.Simultaneously simple in structure, low cost of manufacture (under the situation that adopts the simple glass syringe, its manufacturing cost only quite remote semi-automatic domestic animal filling gun 1/4), be convenient in animal husbandry is produced, popularize.
