Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings, in which several embodiments of the present invention are shown, but the present invention can be implemented in different forms, and is not limited to the embodiments described in the text, but rather, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may be present, and when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present, as the terms "vertical", "horizontal", "left", "right" and the like are used herein for descriptive purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the use of the term knowledge in the specification of the present invention is for the purpose of describing particular embodiments and is not intended to limit the present invention, and the term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a simulated lung with pressure measurement includes a simulated lung main body 1, and is characterized in that: be equipped with lid 2 on the simulation lung main part 1, the top of simulation lung main part 1 is equipped with sampling port 3, be equipped with first air duct 4 on the sampling port 3, the other end of first air duct 4 is equipped with check valve 10, the other end of check valve 10 is equipped with third air duct 8, the other end of third air duct 8 is equipped with bleed valve 9, the other end of bleed valve 9 is equipped with second air duct 7, the other end of second air duct 7 is equipped with manometer 11.
In order to further improve the function of the simulated lung with pressure measurement, the pressure gauge 11 comprises a first pressure gauge 5 and a second pressure gauge 6.
In order to further improve the use function of the simulated lung with pressure measurement, the first pressure gauge 5 and the second pressure gauge 6 are respectively a pointer pressure gauge and a digital pressure gauge.
In order to further improve the use function of the simulated lung with pressure measurement, the simulated lung main body 1 is communicated with the one-way valve 10 through the first air duct 4.
In order to further improve the use function of the simulated lung with pressure measurement, the one-way valve 10 is communicated with the air release valve 9 through a third air duct 8.
In order to further improve the use function of the simulated lung with pressure measurement, the air release valve 9 is communicated with the pressure gauge 11 through a second air guide pipe 7.
The working principle is as follows: when the pressure sensor is used, the sampling port is connected, air is introduced into the one-way valve and the air release valve and then is sent to the digital pressure gauge or the pointer pressure gauge, the air supply pressure of the pipeline of the breathing machine can be read, and the value is compared with the measured value of the breathing machine, so that the quality of the pressure sensor of the breathing machine can be judged. The tidal volume algorithm can be implemented by the following method: the factory calibrates the simulated lung in advance before leaving the factory, because the simulated lung is an elastic device as a whole, and the inflation quantity and the pressure of the simulated lung form a certain relation. The manufacturer calibrates a specific tidal volume in advance, for example, pressure values with a capacity of 300ml and a capacity of 400ml, sets the ventilator to the calibrated capacity value during measurement, and measures the pressure value of the simulated lung at the moment to estimate the deviation value of the tidal volume.
3. The check valve is connected before the pressure gauge because the simulation lung expands and contracts according to the frequency set by the breathing machine when in work, and the numerical value on the pressure gauge jumps up and down at the time and is not easy to be read accurately, so a check valve is added for measuring the pressure highest value in a certain period of time, and because of the one-way conductivity of the check valve, the check valve can only feed air in one direction, and the check valve is closed when the simulation lung contracts, thereby ensuring the stability of reading. After one measurement, the air release valve is pressed down to discharge the gas in the pressure gauge during the last measurement to prepare for the next measurement.
4. After the measurement is finished, the cover covers the sampling port, and the device becomes a common simulated lung for daily use.
5. The measuring device can be integrated on the simulated lung upper splint or can be stored separately.
6. The special detection equipment for the breathing machine is generally worth twenty-three hundred thousand, the detection equipment cannot be purchased by all hospitals, and most hospitals have breathing machines but do not have detection equipment, so that the performance of the breathing machine can hardly be evaluated.
The utility model discloses make the simulation lung become a device that has measurement function under the condition that need not change too much, make the clinical performance that can rely on the device to roughly judge the breathing machine good or bad.
The above description of the present invention is made in conjunction with the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and the method and the technical solution of the present invention are not substantially improved or directly applied to other occasions without improvement, and are all within the protection scope of the present invention.
