Abstract

The invention provides a testing system and a testing method for a respirator. The testing system comprises a testing device, a negative flow generating device and a simulated lung, a valve assembly is arranged in the testing device and connected with the negative flow generating device, the simulated lung and the respirator to be tested through pipelines. The negative flow generating device is used for generating suction flow; a flow sensor and a pressure sensor are further arranged in the testing device, the flow sensor is used for measuring the real-time suction flow of the negative flow generating device, and the pressure sensor is used for measuring the outlet pressure of the respirator to be tested; when the valve assembly is in a first position state, the simulated lung, the testingdevice and the respirator to be tested are communicated; and when the valve assembly is in the second position state, the negative flow generating device, the testing device and the respirator to betested are communicated. According to the scheme, the triggering function of the respirator can be quantitatively tested, and the cost of testing device can be reduced.

Description

technical field [0001] The invention relates to the technical field of equipment testing, in particular to a testing system and testing method for a ventilator. Background technique [0002] There are generally two setting options for the trigger function of the spontaneous breathing of the ventilator: flow trigger and pressure trigger. Among them, the flow trigger refers to the maximum flow that can be generated in the pipeline by the patient's spontaneous inhalation, and the flow range is generally within 0 to 20L / min; the pressure trigger refers to the maximum flow that can be generated in the pipeline when the patient inhales spontaneously. The maximum negative pressure generated in the machine, this value will generally range from 0 to -2kPa. [0003] At present, the methods for testing the trigger function of the ventilator mainly include the following three methods: [0004] The first type is a simulated lung with a certain degree of elasticity, which is artificiall...
