Problems solved by technology

[0009] Since the gas composition, gas concentration, and gas flow rate inhaled and exhaled by the human body are inconsistent under different conditions of time, environment, and state, and the initial conditions are difficult to reproduce, the cardiopulmonary indicators measured each time are always different. The measurement results Poor reproducibility and consistency hampers further research on cardiopulmonary exercise testing

Embodiment Construction

[0056] specific implementation plan

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0058] The first embodiment of the present invention is as figure 1 , figure 2 , image 3 and Figure 4 . Set the device host according to the image 3 One end of the mouthpiece 3207 inserted into the human body is connected to the simulated exhalation interface 2202, and the other end is connected to the simulated inhalation interface 2201.

[0059] Turn on the power of the main unit of the equipment, reset all the parts of the main unit of the equipment, all the solenoid valves are closed, the relative position of the inhalation calibration cylinder pull rod 2503 and the relative position of the exhalation calibration cylinder pull rod 2510 are as follows figure 1 shown.

Abstract

The invention relates to the field of medical instruments and in particular to a respiration simulator for cardiopulmonary exercise testing. The cardiopulmonary exercise testing is gradually popularized in China, and mainly used for the fields of rehabilitation medicine and sports medicine, and capable of providing clinic guide of quantifiable data for preoperative evaluation, postoperative rehabilitation, athletic training and the like, and providing a quantifiable data reference foundation for a clinicist. Because human body inhaled and expired gas components, gas concentration and gas flowrates of a person are not consistent in conditions of different time, environments and statuses, and initial conditions are difficult to be reproduced, cardiopulmonary indexes measured every time aredifferent, and reproducibility and consistency of a measuring result are poor, so further research of the cardiopulmonary exercise testing is hindered. In order to overcome deficiency of the prior art, the respiration simulator for the cardiopulmonary exercise testing is provided, and capable of relatively steadily simulating the human body inhaled and expired gas components, the gas concentrationand the gas flow rates.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a breathing simulator for cardiopulmonary exercise function testing. Background technique [0002] Cardiopulmonary exercise function testing has gradually become popular in China, mainly used in rehabilitation medicine and sports medicine, providing clinical guidance with quantifiable data for preoperative evaluation, postoperative rehabilitation, competitive training, etc., and providing quantifiable data reference for clinicians . [0003] Cardiopulmonary exercise function test generally includes four parts: SVC test, FVC test, MVV test and CPET test. The SVC test, FVC test and MVV test are static pulmonary function tests, and the CPET test is an exercise pulmonary function test. [0004] SVC refers to slow vital capacity. The test indicators mainly include IVC inspiratory vital capacity, EVC expiratory vital capacity, VT tidal volume, IC deep inspiratory volume, VE minute ve...
