Puncture air-exhaust device for ruminal tympany of ruminants

The invention discloses a puncture air-exhaust device for the ruminal tympany of ruminants, and belongs to the technical field of veterinary medical instruments. According to the invention, a puncture air- exhaust needle is provided with an air exhaust part and a medicine injection part at the same time, so that medicines which have the effects of stopping fermentation and curing indigestion, or strengthening hearts and invigorating stomachs are perfused in rumens, and air exhaust can be performed at the same time; in addition, the medicine injection part can be unfolded in the rumens of the ruminants and can inject medicines in a rotation manner, so that when mechanical-strike bubble elimination is performed, bubble chyme is prevented from blocking air exhaust holes, and besides, the perfused medicines can be injected in the rumens at multiple spots, within a large range and in all directions; therefore, the effects of air exhaust, bubble elimination and medicine perfusion are greatly improved. According to the puncture air- exhaust needle provided by the invention, the rotating speed of the medicine injection part can be manually controlled, after the mechanical bubble elimination is performed, the medicines are injected in the rumens; the air exhaust speed can be controlled through an electromagnetic thrust box, the internal air pressure of the rumens can be monitored through a pressure sensor, the working strength of surgeons is lowered, and the surgeons can also be effectively guided to control the air exhaust rhythm and the air exhaust speed.
