Description

Adjustable continuous injector for animal

This utility model relates to a kind of utensil for animals, specifically a kind of adjustable continuous injector for animals.

At present, the all-metal continuous injector for animals on the market is mainly connected to form by storage liquid medicine bottle, injection mechanism and entry needle headstock and a three-way valve assemblies.Injection mechanism is an one handle connecting rod piston formula pushing mechanism, holds fixed handle and can realize continuous injection.This continuous injector for animals, storage liquid medicine bottle and syringe are connected as a single entity, inconvenience during use, cavity on the injection mechanism and piston position relative fixed can not the regulated at will injection volumes, injection volume restricted application during injection.

The purpose of this utility model is exactly in order to overcome the deficiency that existing continuous injector exists, to provide a kind of injection volume adjustable, for animals adjustable continuous injector that the medicinal liquid suction is simple and reliable, easy to use.

For achieving the above object, a kind of adjustable continuous injector for animals, form by injection mechanism, imbibition needle tubing, entry needle headstock and three-way valve assemblies, injection mechanism is an one handle connecting rod piston formula pushing mechanism, the piston base that it is characterized in that injection mechanism is provided with an adjusting device that is made of positioning cap and adjusting silk, and the imbibition needle tubing is connected with three-way valve assemblies one joint by a flexible catheter.

This utility model is regulated on the silk can be provided with the scale sign, so that quantitatively regulate injection volume.

This utility model can quantitatively be injected continuously owing to increased quantitative regulation apparatus on injection mechanism, and adjustable at any time, regulates injection volume; The imbibition needle tubing adopts long flexible catheter to link to each other, and can directly the suction medicine needle tubing of growing be inserted in the ready-made medicinal liquid bottle, has removed the reservoir that the past continuous injector is equipped with oneself, can handled easily, medicinal liquid sucks simple and reliable, reduces liquid waste, accelerates injection speed.

Below in conjunction with accompanying drawing this utility model embodiment is described further:

Fig. 1 is this utility model structural representation, also is the sketch map of embodiment.

Number in the figure is: syringeneedle lock sleeve 1,check lock lever 2,joint 3, three-way valve assemblies 4, joint 5,flexible catheter 6,imbibition needle tubing 7, spanner 8, handle 9, connecting rod 10, cavity 11,spring 12,piston 13,positioning cap 14, adjustingsilk 15.

A kind of adjustable continuous injector for animals is connected to form by injection mechanism, imbibition needle tubing, entry needle headstock and a three-way valve assemblies.The entry needle headstock is made up of syringeneedle lock sleeve 1 and checklock lever 2, and by being threaded,check lock lever 2 is connected with ajoint 3 of three-way valve assemblies 4 between them.Two check valve plugs are arranged in the three-way valve assemblies 4, wherein have with entry needle headstock link can only be to the check valve plug of needle holder output liquid for three-way valve assemblies 4, three-way valve assemblies 4 and imbibitionflexible catheter 6 links have can only be to the injection mechanism check valve plug of medicinal liquid that flows, thereby realizes the suction and the ejaculation of medicinal liquid.Above-mentioned technology belongs to prior art, and this does not describe in detail.

Imbibition needle tubing 7 is connected by a joint 5 of aflexible catheter 6 and three-way valve assemblies 4.Imbibition needle tubing 7 can directly insert medicine bottle, is communicated with by longflexible catheter 6, and imbibition is simple and reliable, has overcome the past syringe and has been equipped with the deficiency of storing the liquid medicine bottle with oneself, and is simple in structure.

The injection mechanism of this adjustable continuous injector for animals is provided with spanner 8, and handle 9, connecting rod 10, cavity 11,spring 12,piston 13, positioningcap 14 are regulated silk 15.Connecting rod 10 1 ends link to each other with spanner 8, the other end links to each other with thepositioning cap 14 ofpiston 13 bottoms, cavity 11 1 ends are connected with the three-way valve assemblies interface, the other end andpiston 13 precision-fit, they are processed by copper material,spring 12 is attached on thepiston 13 between cavity 11 and positioningcap 14, and above-mentioned each part connects, and handle 9 is attached on it.During work, hold handle 9, pull spanner 8, carry connecting rod 10, drivepiston 13 upper and lower activity in cavity 11, finish the suction and the ejaculation of medicinal liquid, reach the purpose of continuous suction, ejaculation.What of injection volume are the size of the range of activity ofpiston 13 in cavity 11 determined.This utility model is provided with by apositioning cap 14 and adjustingsilk 15 adjusting devices that constitute in piston base.Regulatesilk 15 and withstand onpiston 13 bottoms, adjust the relative position ofpiston 13 and positioningcap 14 and connecting rod 11 bottoms by the relative position of threaded adjustingpositioning cap 14 and adjustingsilk 15, therebyadjustment piston 13 is intravital length in the chamber, determines its range of activity, realizes the adjusting of injection volume.Regulate on thesilk 15 and also be carved with quantitative scale sign, can directly determine the range of activity of piston from it, determine the injection volume of injection continuously.And reach adjustable at any time purpose.

This adjustable continuous injector for animals, medicinal liquid sucks simple and reliable, and injection volume is adjustable.Easy to use, applied widely.
