Embodiment 1

[0031] Embodiment 1: The nasal dropper involved in this embodiment mainly includes a pressurization control mechanism and a spray control mechanism.

[0032] Among them, the pressurization control mechanism is designed in the capacity cylinder, and its appearance shows as figure 1 As shown, its internal structure is as Figure 5 shown. from Figure 5 It can be seen from the figure that the main body of the capacity cylinder includes a cylinder body, a top plate and a bottom plate. A piston and a thrust spring seat are set inside the capacity cylinder, and the piston and the thrust spring seat are fixed together by connecting rods to achieve double-layer sealing. The area between the piston and the top plate is a liquid medicine chamber for containing the liquid medicine. The area between the thrust spring seat and the bottom plate is a thrust spring chamber, and in the thrust spring chamber, a thrust spring is connected between the thrust spring seat and the bottom plate. ...

Embodiment 2

[0042] Embodiment 2: on the basis of embodiment 1, a pressurization chamber is provided at the nozzle lower end again, as Image 6 As shown, a thrust plate protruding outward is provided at the lower end of the slide tube, the edge of the thrust plate is a sealing sleeve, the sealing sleeve of the thrust plate is placed in the pressurization chamber, and an exhaust nozzle is provided on the top of the pressurization chamber. It can be seen that the outer diameter of the thrust plate at the bottom of the slide tube is obviously larger than the diameter of the central hole, the lower surface of the slide tube is subjected to the pressure from the liquid medicine chamber, and the rubber gasket is subjected to the pressure from the liquid medicine chamber, but due to the area of ​​the lower surface of the slide tube Larger, it will receive more upward pressure, while the rubber gasket is only subjected to the cross-sectional pressure of the slide tube center tube, so the pressure d...

Abstract

The invention discloses a continuous controllable nasal drip device for veterinary use. The continuous controllable nasal drip device comprises a volume cylinder, a jetting control mechanism, an infusion tube, a nasal drip nozzle and the like; the volume cylinder comprises a cylinder body, a top plate and a bottom plate, and a closed structure is formed. The volume cylinder is preferably cylindrical, a piston and a thrust spring base are sleeved with the volume cylinder and fixed together, the piston is located at the upper side, and the thrust spring base is located at the lower side. The nasal drip device is very easy to operate, medicine jetting output can be controlled simply by pressing a wrench, and meanwhile, the medicine jetting amount can be controlled by controlling the degree and time for pressing the wrench; therefore, the device can achieve the function of freely controlling the jetting amount, and has the function of continuous medicine jetting. Quantitative and controllable nasal drip jetting is conducted aiming at the disease degrees of different individuals in a swine herd, the device obviously has a good therapy effect, and unnecessary medicine liquid waste can beavoided.

Description

technical field [0001] The invention belongs to the field of veterinary nasal drop injection tools, in particular to a veterinary nasal dropper with continuous spraying and controllable spraying degree. Background technique [0002] When pig farms are vaccinated, they usually adopt the nasal drip mode of medicinal liquid. The existing so-called veterinary nasal dropper generally refers to the syringe wearing a nasal drip cannula. The existing improved tool integrated with the syringe for conveniently controlling nasal drop injection is that the injection cylinder and the piston rod are provided with handles respectively, and the purpose of fast and convenient nasal drop injection is achieved by manipulating the handle. However, after the same batch of nasal drop injections, parts such as the syringe and its handle need to be disinfected, but in fact, in order to improve operational efficiency and reduce labor, there are few procedures for performing standard disinfection ope...
