Description

Veterinary injection device with controllable depth

Technical Field

The utility model relates to a controllable beast of degree of depth is with injection device belongs to poultry animal doctor and uses equipment technical field.

Background

An animal veterinarian refers to a physician in the animal husbandry for the prevention, diagnosis and treatment of diseases in domestic animals. When the medicine is injected into the animal, the animal needs to firstly pierce the skin and muscle and then reach the specified depth, and the piston rod is pushed to administer the medicine, so that the injection operation can be completed. However, in some cases, the animals may not be completely matched with the administration due to the stabbing pain, and some animals may even struggle violently, which may present difficulties or challenges to the veterinary practice. One of the difficulties is that the depth of the needle within the animal is uncontrollable due to the struggling of the animal, which can lead to failure or failure to achieve the desired effect.

Therefore, there is a need for an injection device for veterinary use that is structurally sound and has a controlled penetration depth.

SUMMERY OF THE UTILITY MODEL

In order to make up the deficiency of the prior art, the utility model provides a veterinary injection device with reasonable structure and controllable penetration depth, which solves the problems existing in the prior art.

The utility model discloses a realize through following technical scheme:

the utility model provides a controllable beastly medical injection device of degree of depth, includes the needle tubing, set up in the syringe needle of needle tubing front end with set up in piston rod in the needle tubing be equipped with first ring body and the second ring body that is parallel to each other on the needle tubing outer wall, first ring body is located the front side of second ring body evenly be equipped with more than three notch on first ring body and the second ring body first ring body and second ring body are overlapped and are equipped with a rotatory ring body, are equipped with the internal thread on the inside wall of this rotatory ring body all be equipped with a removal strip in the notch, and the anterior segment of this removal strip is the linear type, and the rear end of this removal strip is the arc of outside bending, and the outside of this removal strip is equipped with the teeth of a cogwheel, this teeth of a cogwheel with internal thread on the rotatory ring body meshes mutually the front end of removal strip all is equipped with one and keeps off the pressure body.

Preferably, the retaining and pressing body is an annular retaining ring.

Preferably, the plane of the annular retainer is perpendicular to the axis of the needle, and the annular retainer is elliptical.

Further optimally, the outer side wall of the rotating ring body is provided with anti-slip threads.

Further optimally, the number of the notches is 3.

The utility model has the advantages that:

because the rotating ring body is clamped between the first ring body and the second ring body, the rotating ring body cannot move back and forth when rotating. Because the internal thread on the rotating ring body is meshed with the gear teeth on the moving strip, when the rotating ring body is rotated, the moving strip can be pushed to move back and forth, and the technical effect of adjusting the position of the blocking and pressing body is achieved. When the position of the blocking and pressing body is close to the front, the puncturing depth is limited shallowly, and when the position of the blocking and pressing body is close to the rear, the puncturing depth is limited deeply. During specific injection operation, the position of the pressure blocking body is adjusted in advance according to different injection parts, and when the injection device is used, the penetration depth can be kept unchanged only by applying a pressure forwards. Is particularly suitable for the situation that the penetration depth of animals struggles and is not easy to control.

To sum up, the utility model has the advantages of rational in infrastructure, pierce the controllable degree of depth, be suitable for extensive popularization and application.

Drawings

Fig. 1 is a schematic perspective view of the present invention;

fig. 2 is a schematic view of a three-dimensional structure of the present invention.

In the figure, 1 is a needle tube, 2 is a needle head, 3 is a piston rod, 4 is a first ring body, 5 is a second ring body, 6 is a notch, 7 is a rotary ring body, 8 is a moving strip, 9 is a gear tooth, 10 is an annular retainer ring, and 11 is an anti-skid thread.

Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.

The embodiment provides a veterinary injection device with controllable depth, which comprises a needle tube 1, a needle 2 arranged at the front end of the needle tube 1, and a piston rod 3 arranged in the needle tube 1, wherein the outer wall of the needle tube 1 is provided with a first ring body 4 and a second ring body 5 which are parallel to each other, the first ring body 4 is positioned at the front side of the second ring body 5, the first ring body 4 and the second ring body 5 are uniformly provided with more than three notches 6, a rotary ring body 7 is sleeved between the first ring body 4 and the second ring body 5, the inner side wall of the rotary ring body 7 is provided with internal threads (not shown in the figure), the notches 6 are respectively provided with a movable strip 8, the front section of the movable strip 8 is linear, the rear end of the movable strip 8 is in an arc shape which is bent outwards, the outer side of the movable strip 8 is provided with gear teeth 9, and the gear teeth 9 are engaged with the internal threads on the rotary ring body 7, an annular retainer ring 10 is arranged at the front end of each moving strip 8. The plane of the annular collar 10 is perpendicular to the axis of the needle 2 and the annular collar 10 is oval. The outer side wall of the rotating ring body 7 is provided with anti-skid grains 11. The number of the notches is 3.

When the annular retainer ring is used, because the internal threads on the rotating ring body 7 are meshed with the gear teeth on the moving strip 8, when the rotating ring body 7 is rotated, the moving strip 8 is pushed to move back and forth, and the technical effect of adjusting the position of the annular retainer ring 10 is achieved. When the position of annular retaining ring 10 leans forward, the depth of penetration is spacing less, and when the position of annular retaining ring 10 leans backward, the depth of penetration is spacing darker.

This remove the rear end of strip 8 and be the arc of outside bending, so design, when needing to be changed syringe needle 2, only need rotate rotatory ring body 7 makes it be located the arc position, at this moment, the front end of removing strip 8 can stick up to the outside for annular retaining ring 10 opens, and then the change of the syringe needle 2 of being convenient for. The design of the anti-slip lines 11 can increase friction force, and is convenient for the rotation of the rotating ring body 7.

In conclusion, this embodiment has rational in infrastructure, the controllable advantage of the depth of stabbing, is suitable for extensive popularization and application.

The parts of the present invention not described in detail are the known techniques of those skilled in the art. Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
