Abstract

The invention belongs to the technical field of animal experiment tools and discloses a combined device for tracing thoracic pressure of rabbits. The combined device is provided with a Y-shaped tube;each pipe orifice of the Y-shaped pipe is sleeved with a latex pipe, the pipe orifice at the left end of the Y-shaped pipe is communicated with a Marie air drum through the latex pipe, the Marie air drum is communicated with a tension transducer through a thin rope, the tension transducer is connected with an external computer through a data line, and the Y-shaped pipe is provided with a tension transducer. The pipe orifice at the lower end of the Y-shaped pipe is communicated with a puncture needle head through the latex tube, the Marie air drum is provided with a cylindrical shell, the opening at the upper end of the shell is closed at the lower end, an elastic film wraps the opening at the upper end of the shell, and the lower end of a string is knotted and connected with the center ofthe elastic film. One port of the Y-shaped tube is connected with the external atmosphere, the opening and closing states can be controlled, the pneumothorax condition is prevented, the tension transducer is connected with an external computer to directly present the change of the chest pressure on a computer, the data information is accurately read, a curve is clear and visible and is clear at aglance, and the recording and the analysis are convenient.

Description

technical field [0001] The invention belongs to the technical field of animal experiment equipment, and in particular relates to a combined device for tracing the thoracic pressure of rabbits. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Tracing the pleural pressure curve is a commonly used method or means in pathophysiology and functional experiments. The traditional device for tracing pleural pressure is to use a Y-shaped tube to connect to a "U"-shaped water manometer for recording. One side of the U-shaped tube is It is connected to the atmosphere (opening), and the other side is connected to the connecting pipe (left side) of the "Y"-shaped pipe of the device. The colored water is injected into the U-shaped pipe, and the initial height of the liquid level is "0". With breathing movement, The liquid level in the U-shaped tube will change, and the value of this change is the chest pressure valu...
