Embodiment Construction
[0018] The present invention will be further described now in conjunction with accompanying drawing
[0019] An intelligent gas supply device for patients that prevents the ping-pong effect, including the gas supply device. Programs include: initialization display, port, key scan subroutine; display subroutine; key processing subroutine; pressure measurement subroutine; calculation control subroutine; pressure alarm subroutine; Shut down, eliminate the "ping-pong" effect, and achieve the best gas supply to the patient;
[0020] Its overall structure is: an air and oxygen mixing device 5, one input end of which is connected to the output end of the oxygen cylinder 8, and the other input end is connected to the total end 4 of the two-position three-way ventilation valve 4 controlled by the automatic switching device 3 -2 is connected, and the other two transfer terminals 4-1 and 4-3 are respectively connected to the output terminal of the central air supply 1 and the output ter...

The invention relates to an intelligent air-supply device for preventing the ping-pong effect, which belongs to the technical field of medical appliance. The intelligent air-supply device is characterized in that the air-supply device is controlled by a singlechip which is provided with application software; the application software consists of a main program and derivative subprograms which comprise an initialized display, port and key scan subprogram, a display subprogram, a keystroke processing subprogram, a pressure measurement subprogram, a computing control subprogram and a pressure alarm subprogram; and time delay startup and time delay shutdown are led into the computing control subprogram to eliminate the 'ping-pong' effect, so that optimum air supply to patients is realized. Theintelligent air-supply device has the advantages that an automatic control device can be automatically switched to an air compressor when the center can not supply air normally, so that the 'ping-pong' effect can be effectively eliminated; and sound and light alarm can be generated when the output pressure is low, so that uninterrupted operation of the air-supply device is guaranteed. Moreover, the intelligent air-supply device eliminates the fear of trouble in the rear of the patients and doctors, and provides technical support for the use of air supply of the center in a large range.
Description
technical field [0001] It belongs to the technical field of medical equipment. Background technique [0002] The patented technology (200720072330.7) introduced "an automatic switching device for patient gas supply", which adopts the pressure relay control switching technology. When the central gas supply is lower than a certain value, the pressure controller automatically switches to a small The compressor realizes uninterrupted air supply to the patient. In actual use, when the central air supply pressure fluctuates with a certain frequency and amplitude, it will cause the pressure controller to be turned on and off frequently (commonly known as "ping-pong effect"). Make the air compressor start and stop frequently. Make the back-stage air-consuming equipment not work normally, and in severe cases, the air compressor and other parts will be damaged; it is also impossible to realize a stable air supply to the patient. Contents of the invention [0003] The invention pr...
