Description

A kind of animal low pressure needleless injector

Technical field

This utility model relates to medical instruments field, particularly a kind of animal low pressure needleless injector.

Background technology

The society continuous progress so that people's material life also be improved, people also will regularly irregularly prevent and treat animal when cultivated animals, just need drug injection this moment, and generally speaking now the raiser on the market substantially all be the cartridge syringe that uses with syringe needle, there are the following problems for it: at first syringe needle is easily broken, the injection personnel are injured because of the struggle of animal in epidemic prevention, and the unexpected fracture accident of syringe needle very easily occurs in injection process; Secondly cross infection easily occurs, because many peasant households in order to save cost, often do not change syringe needle, so that there is larger cross infection risk in whole immunologic process; Again be unfavorable for absorbing fast drug effect, traditional needle injection, medicament forms bulk in the injection site, is unfavorable for absorbing; Again because traditional needle injection causes high amount of drug to concentrate on a point, can't be completely absorbed, thereby form drug residue.

Therefore be necessary traditional band syringe needle cartridge syringe is carried out further technological innovation.

The utility model content

The purpose of this utility model is for the defective of prior art and deficiency, provides a kind of simple in structure, and a kind of animal low pressure needleless injector reasonable in design, easy to use adopts the needleless technology, without the broken needle risk; Have painless or the hypodynia liquid medicine injection, alleviate the animal burden; Can collective's injection cross infection can not occur; Its easy to operate simple, energy-conserving and environment-protective.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of animal low pressure needleless injector described in the utility model, it comprises trigger component, white push-rod assembly, medicated core assembly, barrel assembly, front lumen assembly, Handleset, dosage adjusting knob, dosage adjusting parts, dosage adjustment screw, takes out cartridge module, face seal, big spring, air valve push-rod assembly, pushing rod sleeve coil assembly, acoustic filter and little spring, described barrel assembly left end is provided with the medicated core assembly, and right-hand member trigger component left end links to each other; The right-hand member of described trigger component links to each other with front lumen assembly left end; Described front lumen assembly right-hand member links to each other with the Handleset left end; Described Handleset right-hand member is provided with the dosage adjusting knob; Be provided with the dosage adjustment screw on the described dosage adjusting knob; The described cartridge module of taking out is arranged on the Handleset in the lumen, and its right-hand member is provided with dosage and regulates parts; Described dosage is regulated parts and is arranged on the Handleset in the lumen; Described white push-rod assembly is inserted under the Handleset in the lumen; Described little spring, pushing rod sleeve coil assembly, air valve push-rod assembly and big spring from left to right are successively set under the Handleset in the lumen; Described face seal is arranged on lumen right-hand member under the Handleset; Described two acoustic filters are arranged on the Handleset handle bottom.

Further, described taking out between cartridge module and the dosage adjusting parts is provided with insert;

Further, be provided with pad on the described dosage adjustment screw;

Further, be provided with wheel flange between described little spring and the pushing rod sleeve coil assembly.

After adopting said structure, this utility model is compared with traditional needle-based cartridge syringe, and beneficial effect is: first, owing to adopting the needleless injection, can not produce because animal struggles and the problem of broken needle occurs, can not stay because of syringe needle yet and occur in the animal body not eaten by the people, and cause accident; The second, can not avoid having larger cross infection risk in immunologic process because the raiser causes the multiplex phenomenon of a pin because saving cost, thus the generation that reduces or stop epidemic situation; The 3rd, owing to use the needleless design, thereby can not produce medical waste, environmental protection and energy saving.

The specific embodiment

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

As shown in Figure 1, a kind of animal low pressure needleless injector described in the utility model, it comprises trigger component 1, white push-rod assembly 2, medicated core assembly 3, barrel assembly 4, front lumen assembly 5, Handleset 6, dosage adjusting knob 8, dosage adjusting parts 9, dosage adjustment screw 10, takes out cartridge module 11, face seal 12, big spring 13, air valve push-rod assembly 14, pushing rod sleeve coil assembly 15, acoustic filter 16 and little spring 18, described barrel assembly 4 left ends are provided with medicated core assembly 3, and right-hand member trigger component 1 left end links to each other; The right-hand member of described trigger component 1 links to each other with front lumen assembly 5 left ends; Described front lumen assembly 5 right-hand members link to each other with Handleset 6 left ends; Described Handleset 6 right-hand members are provided with dosage adjusting knob 8; Be provided with dosage adjustment screw 10 on the described dosage adjusting knob 8; The described cartridge module 11 of taking out is arranged on the Handleset 6 in the lumen, and its right-hand member is provided with dosage and regulates parts 9; Described dosage is regulated parts 9 and is arranged on the Handleset 6 in the lumen; Described white push-rod assembly 2 is inserted in 6 times lumens of Handleset; Described little spring 18, pushing rod sleeve coil assembly 15, air valve push-rod assembly 14 and big spring 13 from left to right are successively set in 6 times lumens of Handleset; Described face seal 12 is arranged on 6 times lumen right-hand members of Handleset; Described two acoustic filters 16 are arranged on the Handleset 6 handle bottoms.
