Abstract
The utility model discloses a multifunctional medicine feeding gun, which adopts the technical proposal that the shape is a gun shape, the upper part of a handle is composed of a medicine conveying conduit, an injection cavity and a fixed interface in front of the injection cavity, the rear part of the medicine conveying conduit is provided with a medicine feeding pot connecting interface, a needle head seat is arranged on the fixed interface, and a medicine feeding pipe can also be arranged on the fixed interface and is fixedly connected on the fixed interface by a fixed nut. One-way valves are arranged at the inlet and the outlet of the injection cavity. The advantages are that it can be used continuously, it does not need intermediate charging step, it can be used for intramuscular injection, and also can be used for pouring medicine by oral administration, and it has multiple purposes. The device has the advantages of simple structure, advanced process, convenient operation, high working efficiency and long service life.
Description
This utility model relates to a kind of multi-functional injection gun, belongs to the animal medical instruments field.
Up to the present, carry out intramuscular injection to animal, all adopt conventional apparatus injection, bottled perfusion is adopted in perfusion, very inconvenience during operation.Still also be not specifically designed to the utensil of animal muscle injection, or the utensil of perfusion for oral administration.
The purpose of this utility model be to provide a kind of simple in structure, practical, need not in the middle of the powder charge link, not only can be used for the animal muscle injection, and can be used for the multi-functional injection gun of animal perfusion for oral administration.
The purpose of this utility model is implemented by following technical scheme: its external form is " a rifle type ", its handle is made up of front hand grip and back handle, there is a reset tension spring to link to each other with the horizontal little hook of back handle bottom in the front hand grip inboard, there is a nut bore front hand grip bottom below, and the fixing stop nut of set screw and of regulating the scale effect is together arranged in nut bore.Fixed interface before the top of front hand grip and back handle is infusion administering catheter, injecting cavity and injecting cavity is formed, and is dispensing kettle connecting interface at the rear portion of described infusion administering catheter; In the transfusion catheter front portion is injection ram; On described fixed interface top is screw thread, and hold-down nut is threaded with fixed interface, on described fixed interface needle holder is installed, and also drug tube can be installed, and is fixedly connected on the fixed interface by hold-down nut.There are a check valve in the front portion of described infusion administering catheter, the import department of injecting cavity, are with a spring on the described check valve, are provided with check valve again in the exit of injecting cavity, fixed interface, are with a spring on this check valve.
Described needle holder can adopt existing specification on the market.
The front portion of described drug tube is curved slightly.
Described check valve, form by three parts, the front portion is long slightly triangular prism structure, middle is that round vase covers shape, in round vase lid shape lid inboard is the triangular prism structure of lacking slightly, for round vase covers on alternate place of structure and the rib at triangular prism three little grooves is arranged with middle for long slightly triangular prism structure in described front portion.
Operation principle of the present utility model is: multi-functional injection gun adopts the principle design of independent check valve relativity to form.
By holding fixed handle injection ram compressing medicinal liquid is flowed forward, at this moment, the outlet check valve is under the injection ram effect, overcome the active force of unidirectional spring and open, simultaneously, make the check valve of inlet under the active force of spring, be in closed condition, finish the dispensing task.
After the release handle, injection ram resets under the effect of back-moving spring, and the exit check valve is closed under the effect of spring, make and form negative pressure in the injecting cavity, this negative pressure overcomes the active force of inlet one-way valve spring and makes its unlatching, medicinal liquid enters in the injecting cavity by injecting transfusion catheter in the kettle automatically, so comes and goes the circulation continuous operation.
The utility model has the advantages that: can use continuously, the powder charge link promptly can be used as intramuscular injection in the middle of need not, and oral administration perfusion again also can be used for cast (back of the body), and a rifle is used more.This injection gun is simple in structure, and technology advanced person is easy to operate, high efficiency, and long service life is suitable for inside and outside anthelmintic, vaccination, the control injection of pastoral area and groupment stock raising especially and waters back of the body use.Dosage is accurate, and error amount only is+0.1 milliliter.High efficiency is ten times to tens times of conventional dispensing efficient.The manufactured materials of this injection gun has taked advanced aseptic technic to handle, and the life of product phase can reach more than 10 years.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an overall structure generalized section of the present utility model.
Fig. 2 is equipped with the structural representation of drug tube for this utility model fixed interface front portion.
Fig. 3 is the right view of this utility model check valve.
Fig. 4 is the front view of this utility model check valve.
Fig. 5 is the B place enlarged diagram of Fig. 4.
Fig. 6 is the left view of this utility model check valve.
As shown in Figure 1, external form is " a rifle type ", its handle 1 is made up of front hand grip 2 and back handle 3, there is a reset tension spring 4 to link to each other with the horizontal little hook 5 of back handle 3 bottoms in front hand grip 2 inboards, there is a nut bore 6 front hand grip 2 bottoms belows, and the fixing stop nut 8 of set screw 7 and of regulating the scale effect is together arranged in nut bore 6.Fixed interface 11 before the top of front hand grip 2 and back handle 3 is infusion administering catheter 9, injecting cavity 10 and injecting cavity 10 is formed, and is dispensing kettle connecting interface 12 at the rear portion of infusion administering catheter 9.In transfusion catheter 9 front portions is injection ram 15; On fixed interface 11 tops is screw thread, and hold-down nut 16 is threaded with fixed interface 11, and needle holder 17 is installed on fixed interface 11, as shown in Figure 2, also drug tube 18 can be installed, and is fixedly connected on the fixed interface 11 by hold-down nut 16.Needle holder 17 can adopt existing specification on the market.The front portion of drug tube 18 is curved slightly.There is a check valve 13 in the import department of the front portion of infusion administering catheter 9, injecting cavity 10, is with a spring 14 on the check valve 13, is provided with check valve 13 again in the exit of injecting cavity 10, fixed interface 11, is with a spring 14 on this check valve 13.
