Description

Veterinary injection device

Technical Field

The utility model relates to the technical field of injectors, in particular to veterinary injection device.

Background

In the process of livestock breeding, a veterinary injector is often required to be used for injecting medicines or vaccines into livestock in batches, and a continuous injector is used as one of the veterinary injectors, so that the complex step that the traditional injector needs to repeatedly absorb medicaments is omitted due to continuous administration, the injection operation efficiency is greatly improved, and the continuous injector becomes one of injection instruments widely adopted in the livestock breeding.

However, in order to facilitate administration of the existing continuous injector, the medicine bottle is generally arranged above the front end of the continuous injector, the arrangement mode causes the gravity center of the continuous injector to be higher, the continuous injector is difficult to keep balance during use, inconvenience is brought to injection operation, especially when livestock feel pain and struggle in the injection process, the livestock can be injured by carelessness, and the needle head is bent or falls off.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a veterinary injection device, which improves the position of a medicine bottle to keep balance when in use, thereby facilitating injection.

In order to achieve the above object, the present invention is realized by the following technical solutions:

the utility model provides a veterinary injection device, includes the continuous injection subassembly, the continuous injection subassembly package injection tube and syringe needle, the front end of injection tube is equipped with out the medicine mouth, and it links to each other with the syringe needle through first check valve to go out the medicine mouth, first check valve only allows injection liquid to flow to the syringe needle direction from the injection tube, and the injection tube front portion is equipped with into medicine mouth, and the injection tube rear portion is equipped with the handle, still includes the bottle, the bottom mounting of handle is provided with the bottle lid, bottle and bottle lid threaded connection still are provided with intake pipe and imbibition subassembly on the bottle lid, the imbibition subassembly includes second check valve and pipette, second check valve vertical fixation sets up on the bottle lid, and the bottom of second check valve links to each other with the pipette, and the top passes through the hose and links to each other with into medicine mouth, and the second check valve only allows injection liquid to flow to advance medicine mouth direction from the bottle.

Furthermore, continuous injection subassembly still includes piston rod and reset spring, the front end of piston rod passes through piston and injection tube sliding fit, and the rear end of piston rod is equipped with presses the seat, and the rear end of injection tube is coaxial to be equipped with the spacing ring, and the piston rod is worn to establish in the spacing ring, and the piston rod is located to press and is equipped with reset spring on the body of rod between seat and the spacing ring. It should be apparent that the inlet port in the barrel should be as close as possible to the front end of the barrel to prevent the plunger from passing over the inlet port as it approaches the front end of the barrel and allowing the injectate to flow into the rear end of the barrel.

Further, the bottom of bottle is equipped with the arc arch, and the bellied convex surface of arc is inboard towards the bottle, and the arc arch forms the collecting tank with the bottle lateral wall, the pipette is the hard pipe, and the free end of pipette extends the bottom of collecting tank. When the amount of the residual injection liquid in the bottle body is reduced, the residual injection liquid can be concentrated in the liquid collecting tank by the arrangement, and the liquid suction assembly is convenient to suck the residual injection liquid into the injection tube.

Further, the free end of the pipette is tapered. The arrangement of the free end necking of the pipette accelerates the flow velocity of the injection at the necking to generate a low pressure area, so that the suction force of the pipette to the injection is increased, and the injection can be more effectively sucked into the pipette.

The utility model also comprises other components which can make the veterinary injection device normally used, and all belong to the routine selection in the field. In addition, the device or the assembly which is not limited in the utility model adopts the conventional means in the field, for example, the injection tube, the needle, the first check valve, the second check valve, the handle, the hose, the air inlet pipe, the reset spring and the like all adopt the conventional arrangement.

The utility model discloses a theory of operation:

when using this device, threaded connection is to the bottle lid behind the injection liquid of packing into in the bottle, hold the handle, make the syringe needle of this device up, press and press the seat, the piston is pressing down to the front end motion of injection tube, extrude the air in the injection chamber that injection tube and piston formed, loosen and press the seat, the piston is under reset spring's effect to the rear end motion of injection tube, because first check valve has prevented that the air from passing through the syringe needle and getting into the injection chamber, so injection intracavity pressure diminishes, injection liquid in the bottle loops through imbibition subassembly and hose under the effect of pressure differential and is inhaled the injection chamber, and can not flow back to in the bottle under the effect of second check valve, press the seat many times until injection liquid is full of the injection chamber, can begin the injection operation: the needle head is inserted into the livestock body, the pressing seat is pressed, a certain dosage of injection is injected into the livestock body, the needle head is pulled out, the pressing seat is loosened, the piston moves towards the rear end of the injection tube under the action of the reset spring, the injection in the bottle body is sucked into the injection cavity under the action of pressure difference so as to be used for next injection, and continuous injection can be realized by reciprocating.

Compared with the prior art, the beneficial effects of the utility model are that:

the bottle body is arranged at the lower end of the handle of the continuous injector, so that the center of gravity of the whole continuous injector is concentrated near the handle, and an operator can operate the device more conveniently; meanwhile, the device is matched with the bottle body through the liquid suction assembly, so that when the amount of the residual injection in the bottle body is reduced, the residual injection can be conveniently sucked into the injection cavity, and the waste of the injection is reduced.
