[0047] In modern clinical medicine, as an effective means to artificially replace the self-ventilation function, the ventilator has been widely used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine. The ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, save and prolong the lives of patients.

[0048] At present, the common ventilators on the market all have a leakage monitoring function. However, when verifying the minute leakage accuracy of the ventilator in the current research and development process, the common adapter leakage port aperture has only a few specifications, resulting in that the step size and upper and lower limit range of the test case are limited when using these accessories for testing. However, it is difficult to control the cost of a leakage tool designed specifically for verification experiments, and it is time-consuming and laborious.

[0066] Based on the comparison result, the leakage monitoring accuracy of the measured ventilator is verified.

[0067] In specific implementation, in this embodiment, after calculating the actual minute leakage and the actual minute leakage rate corresponding to the target pipeline based on the minute ventilation through the target pipeline recorded by the measured ventilator during the ventilation process and the minute ventilation through the exhalation valve recorded by the simulated leakage ventilator, then, based on the actual minute leakage and the actual minute leakage rate, it is compared with the monitored minute leakage and the monitored minute leakage rate detected by the measured ventilator, finally, based on the comparison result, the leakage monitoring accuracy of the measured ventilator is verified.

[0068] Further, the leakage simulation test method, wherein, as shown in Figure 3 The exhalation valve 100 comprises, from top to bottom, a leakage chamber 4, a diaphragm 3, a thimble 2 and a voice coil motor 1;

[0069] The bottom end of the thimble 2 is connected with the voice coil motor 1, the top end of the thimble 2 is connected with the diaphragm 3, the voice coil motor 1 can drive the thimble 2 to move up and down when working, and in turn drive the diaphragm 3 to move up and down.

[0070] When the diaphragm 3 moves to abut the bottom of the cavity 41 of the leakage cavity 4, the cavity opening 42 of the leakage cavity 4 can be closed; when the diaphragm 3 moves to non-abut the bottom of the cavity 41 of the leakage cavity 4, a leakage gap 5 is formed between the leakage cavity 4 and the diaphragm 3.

[0071] Further, the leakage simulation test method, wherein, as shown in Figure 3 The voice coil motor 1 includes a shell 11, an iron core 12, a permanent magnet 13, an armature skeleton 14 and a coil 15.

[0072] The shell 11 is a hollow structure with one end open and one end closed, the iron core 12 is vertically arranged at the shaft center of the closed end of the shell 11, and the iron core 12 and the shell 11 are an integral structure, the permanent magnet 13 is arranged on the inner side wall of the shell 11, the armature skeleton 14 is coaxially sleeved on the iron core 12, and the armature skeleton 14 can slide up and down relative to the iron core 12, and the coil 15 is wound on the outer side wall of the armature skeleton 14.

[0075] In the embodiment, the working principle of the exhalation valve 100 is as follows: the coil 15 (conductive conductor) after being electrified is subjected to a force in a magnetic field (generated by the permanent magnet 13), which is the Lorentz force, and the size of the force is proportional to the current on the coil 15. When the current in the coil 15 is i and the magnetic field intensity is B, the conductive conductor is subjected to a force, which is the electromagnetic force. In the embodiment, the size of the electromagnetic force is F, and the direction can be determined according to the left-hand rule. If N conductive wires with a total length of L are placed in the magnetic field, the force on the coil 15 can be represented by the formula F = NBiL. When the size of the current i in the coil 15 is changed, the upward thrust F (coil 15→armature frame 14→top pin 2) of the top pin is also changed. At this time, the opening degree of the leakage gap 5 is different, and the leakage is also changed. In this way, the exhalation valve 100 provided by the embodiment can change the size of the leakage gap 5 in the valve at will. That is, in the embodiment, the exhalation valve 100 can control the simulated leakage ventilator 200 to leak gas according to the set parameters (simulate different leakages), so as to achieve the effect of controlling various degrees of leakage. The embodiment does not need to design a new leakage tooling, saves cost, and can meet the parameter verification needs of the measured ventilator 300 under different leakages at zero cost and simply and efficiently, that is, the test needs can be well met.
