Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0040] Such as Figure 1 to Figure 8 As shown, the invention discloses a method for measuring animal respiratory indexes in a non-invasive and non-invasive method. Pulmonary function tests can be repeated on the same animal. The activities, eating and drinking of animals are not restricted, it is easier to operate, the influence of the operator's proficiency on the experiment is relatively small, there is no influence of air leakage and animal struggle, etc.
[0041] The invention includes a reference...

The invention provides a device for noninvasive measurement of animal respiration indexes. The device comprises a reference cabin, a test cabin, a pressure sensor, a damper and a data acquisition device, and the damper balances airflow between the test cabin and the reference cabin; the pressure sensor is used for detecting respiration signal values of the reference cabin and the test cabin respectively and is connected with the data acquisition device through an electric wire; and a gas circuit interface is arranged on the test cabin. According to the invention, the respiration of the animal is measured in a noninvasive mode, anesthesia is not needed, and respiration detection is realized without intubation. By adopting a noninvasive mode, the animal can be sober and freely move during measurement, and long-time monitoring and repeated measurement can be carried out on one animal. By arranging a damping structure, a signal balancing function is realized. Through bias flow air supply and continuous air exchange, it is guaranteed that animals breathe fresh air, and carbon dioxide is prevented from being stored. The online atomization function is realized through an atomization dosing port. The received respiration signal value is detected and calculated through a set program.
Description
technical field [0001] The invention relates to the field of breath detection, in particular to a device for non-invasively measuring animal breath indexes. Background technique [0002] Animal experiments are of great significance to the study of the etiology, pathogenesis, pathophysiology and treatment of human diseases, and the establishment of animal models has its special value. In the study of animal models of the respiratory system, the pulmonary function test of experimental animals is always a thorny problem. Especially small animals used in large-scale experiments, such as mice, rats, etc., are very difficult to measure because the respiratory volume of animals is too small compared with the human body. In the traditional method of testing animal breathing through anesthesia and endotracheal intubation, the measured signal cannot actually reflect the normal breathing parameters of the animal due to the intervention of anesthesia and surgery in the process.
