Abstract

The invention relates to a medical instrument, in particular to a pika experiment animal shape of the tips mouth gag, which is characterized in that the instrument is provided with an upper jaw support frame (1) and a lower jaw support fame (2); an opening is formed between the upper jaw support frame (1) and the lower jaw support frame (2); the two ends of the upper jaw support frame (1) and the lower jaw support frame (2) are provided with an adjusting screw (3); being matched with the adjusting screw (3), the upper jaw support frame (1) or the lower jaw support frame (2) is provided with a thread (4); the upper jaw support frame (1) and the lower jaw support frame (2) respectively take on an arch shape or an M shape and are symmetrically arranged; the upper jaw support frame (1) and the lower jaw support frame (2) are made of rubber, plastic or stainless steel material. The instrument fully uses the features of fore-tooth of the pika experiment animal and can quickly the open oral cavity of animals by simple operations to ensure that the opening position of the animas is kept and difficult to drop off, thus improving the safety, accuracy and repetitiveness of the animal experiment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pika lab animal lip mouther for animal experiments. Background technique [0002] When experimenting with pika experimental animals, repeated intragastric administration is often required. At present, there is no special opening device for pikas. Due to the unskilled initial technique or the stimulation of experimental animals, the experimenters are easily bitten and injured, or even infected. And deadly. Excessive struggle of experimental animals may cause the liquid medicine to pour into the lungs or bite the experimenter. Contents of the invention [0003] The object of the present invention is to provide a simple, safe and reliable lip mouther for pika experimental animals aiming at the problems mentioned above. The technical scheme adopted to realize the present invention is: the present invention is provided with an upper jaw bracket and a lower ja...
