Abstract

The utility model provides a multifunctional continuous syringe for an animal. The utility model is characterized in that a single way between the injection cylinder of an existing metal syringe and a needle head is replaced by a three way; the upper through hole of the three way is connected with the injection cylinder, and the lower through hole which comprises a one-way valve piston is connected with the needle head of the syringe; the bottom end of a side through hole is provided with a one-way valve piston; an outlet is connected with a medical liquid bottle through a perfusion pipe; a regulating nut for dosage which is originally arranged on a pushing rod outside a glass pipe is arranged in the glass pipe; the upper end of the pushing rod is matched with a pressure spring. The syringe of the utility model does not need to repeatedly pump medicine. The injection efficiency is high, and the dosage is accurate. The utility model is especially suitable for injecting group animals and fishes. When the three way is taken away, the utility model can be used for injecting an individual animal for treating disease. The manufacturing cost is low.

Description

Multi-functional continuous injector for animals

This utility model belongs to apparatus for animals, specifically a kind of multi-functional continuous injector for animals.

Just use two kinds of syringes when at present livestock and poultry farm, professional raising farmer and animal and veterinary stand in the jumpbogroup poultry are treated or inoculate mostly, a kind of is single-body type, promptly injected and once need take out medicinal liquid one time, inefficiency, trouble, dosage are difficult for grasping accurately: another kind is special-purpose continuous injector, but its cost height (70～80 yuan/pay), and only be suitable for injection continuously and can not be used for the monomer injection.

The purpose of this utility model provides a kind ofly improves the continuous injector multi-functional for animals form by the single-body type Luer's syringe, and it does not need to extract repeatedly medicinal liquid and can inject continuously and again can be when monomer is treated use by the common metal syringe and carry out the monomer injection the jumpbogroup poultry.

In order to achieve the above object, this utility model is taked following solution: this continuous injector for animals comprises injection tube and injection needle, it is characterized in that, it also comprises: a threeway and a stage clip, stage clip is the push rod top that is contained in injection tube, the last through hole of the vertical direction of threeway is connected with the fluid infusion port of injection tube, the lower through-hole that port contains one-way valve piston (2) is connected with the inlet of injection needle, port contain the side through hole of one-way valve piston (23) and vertical direction on, lower through-hole at an angle of 90, an end that connects tube for transfusion, the other end of tube for transfusion then inserts in the bottleneck of medicinal liquid bottle by the transfusion head, also is inserted with a muffler on the medicinal liquid bottleneck.

On the push rod of injection tube, also be provided with a dosage adjusting nut that is contained in the glass-tube.

The utility model has the advantages that: 1, do colony's injection and need not to extract repeatedly medicinal liquid, speed is fast, the efficient height, dosage is accurate, taking down accessories such as threeway changes the single-pass of virgin metal syringe and also can be used for the injection of curing the disease of individual poultry, so it is very convenient: 2, applied range, because injected dose can be regulated (annotate: single head dosage was many below 5ml when general poultry jumpbogroup was injected) in the following scope of 5ml arbitrarily, so both can be used for the injection of jumpbogroup domestic animal, also can be used for the injection of poultry and Fish: in addition, because of after taking off syringe needle, liquid is the scattering ejection, uses so also can do the small size aerosol apparatus.3, cost is low, and cost only is 1/5 of a special-purpose continuous injector; 4, durable, not fragile.

Fig. 1 is the overall structure sketch map of this syringe.

Fig. 2 is the three-port structure cutaway view among Fig. 1.

Below in conjunction with accompanying drawing this utility model is described in further detail.

1 is syringe needle in Fig. 1, its length thickness can be according to injection object choice adapted, the 2nd, the one-way valve piston of threeway lower through-hole, make of gum elastic, it is upwards closed when extracting medicinal liquid, open downwards during injection, the 3rd, threeway, its cutting ferrule is connected in the metal tube 4 and (puts into from the metal tube upper end), metal tube has the strip window, so that can observe the medicinal liquid in the glass tubing, the 5th, the caulking gum packing ring, it is contained in the lower end of glass tubing 6, in case medicinal liquid seepage, glass tubing and packing ring are enclosed within the metal tube, be set with again in the glass-tube and be threaded and graduated push rod 7, drawing liquid rubber piston 8 and auxiliary rubber piston 9 are housed again on the push rod, also have the location rubber ring 10 of fixed dosage adjusting nut 11 usefulness and can be on push rod in glass-tube up and down the dosage adjusting nut 11 of turn (annotate: the identical and prior calculation of general every the dosage of jumpbogroup injection well, so can mix up the position of this nut on push rod by required dosage in advance puts it in the glass-tube again), metal tube 4 upper ends are fixed on glass-tube 6 in the metal tube with hold-down nut lid 17, the 16th, the attacker is convenient to forefinger and middle finger is held syringe, the push rod exposed portions serve that covers face at hold-down nut is with stage clip 12, the 13rd, top duroplasts sleeve pipe, be used for the extreme position that definite push rod moves downward, it is exactly injected dose to the scale difference between 13 lower ends that hold-down nut after promptly regulating by the dosage adjusting nut covers 17 upper ends, the 15th, the pusher grip of band nut presses pusher grip piston 8 extruding medicinal liquids are sprayed from needle point during injection.The side through hole of threeway 3 connects an end of latex tube for transfusion 18, in the bottleneck of 18 the other end by transfusion 20 an insertion medicinal liquid bottle 21, turns back to trachea 19 on the bottleneck.

Fig. 2 is a three-port structure cutaway view among Fig. 1.As seen from the figure, this threeway vertical direction is provided with through hole 25, lower through-hole 22 and side logical 27, side is logical to be connected with main body by screw thread, leakproof cushion rubber 14 is arranged therebetween, the lower end 24 of the port of lower through-hole 22 and side logical 27 is tapered slightly and be provided with one-way valve piston 2 and one-way valve piston 23, and piston is a wire nail shape, makes of gum elastic, the afterbody of piston 2 passes through hole and is fixed by plastic tube 26 jam-packs, and piston 23 afterbodys pass side through hole and fixed by plastic tube 28 jam-packs.The effect of two pistons is alternations, when push rod 7 is upwards taken out, occurs negative pressure in the glass-tube, and piston 2 is closed, and piston 23 is opened, and medicinal liquid enters in the injection tube from side is logical; When push rod 7 presses down, piston 23 is closed, and piston 2 is opened, and medicinal liquid promptly is extruded from injection needle and sprays.
