Detailed Description
Referring to fig. 1 to 8, the gas leakage alarm device for the online on-line use of the dry powder barrel comprises a pressure sensor 1, an a/D converter 2, a single chip microcomputer 3, an alarm device 4, a power supply 6, a switch 7, an elastic sealing ring 8 and a shell 9, wherein the elastic sealing ring 8 is sleeved at the heat seal joint of a barrel body D and a barrel cover E of the dry powder barrel, an air outlet pipe 80 is arranged on the elastic sealing ring 8, the pressure sensor 1 is arranged in the air outlet pipe, the pressure sensor 1, the a/D converter 2, the alarm device 4, the power supply 6 and the switch 7 are connected with the single chip microcomputer 3, and the single chip microcomputer 3 is connected with the air outlet pipe 80 through the shell 9.
Furthermore, a signal amplifying circuit board 5 is connected between the pressure sensor 1 and the a/D converter 2, and a signal amplifying circuit is etched on the signal amplifying circuit board 5.
More specifically, the alarm device 4 is a buzzer or an alarm lamp.
Furthermore, the housing 9 is provided with a threaded connection pipe 10, and the housing 9 is in threaded connection with the air outlet pipe 80 through the threaded connection pipe 10.
More specifically, the elastic sealing ring 8 includes an end sealing piece 81, a connecting sealing piece 82 and a barrel wall sealing piece 83, and the end sealing piece 81 is integrally connected with the barrel wall sealing piece 83 through the connecting sealing piece 82.
Furthermore, a cavity 84 for air to flow is formed between the connecting sealing sheet 82 and the outer wall of the dry powder barrel body D, and if liquid leaks between the powder barrel bodies D and the barrel covers E, the cavity 84 can store part of dialysate to protect the pressure sensor 1, the a/D converter 2, the single chip microcomputer 3, the alarm device 4, the power supply 6 and the electronic elements related to the switch 7.
More specifically, the pressure sensor 1 is a resistance strain gauge pressure sensor.
Furthermore, the model of the a/D converter 2 may be selected from ADC 0832.
Furthermore, the type of the single chip microcomputer 3 can be an AT89C51 single chip microcomputer.
The utility model discloses a theory of operation and use:
referring to fig. 1 to 8, when in use, the elastic sealing ring 8 is sleeved from the bottom of the dry powder barrel body D, the elastic sealing ring 8 moves towards the dry powder barrel cover E, when the barrel wall sealing sheet 83 of the elastic sealing ring 8 moves to the lower part of the connecting lug of the dry powder barrel body D, the elastic sealing ring no longer moves towards the dry powder barrel cover E, meanwhile, because the barrel wall sealing sheet 83 is made of elastic material, the sealing sheet can be tightly sleeved on the outer wall of the dry powder barrel body D to prevent air leakage, the end cover sealing sheet 81 is clamped at the upper end of the edge of the dry powder barrel cover E, the clamping effect is shown in fig. 6, the dry powder barrel is integrally connected to dialysis equipment, the switch 7 is opened, the pressure sensor 1 starts to work at the moment, the air tightness of the sealing port of the dry powder barrel cover E and the dry powder barrel body D is detected in a heat sealing manner, if air leakage occurs, the air in the dry powder barrel cover overflows to the cavity 84 through the gap between the dry powder barrel body D, the pressure C in the cavity 84 will provide a pressure signal to the pressure sensor 1, the pressure sensor 1 will convert the pressure C signal into an electrical signal, the electrical signal converted by the pressure sensor 1 may be relatively small, so we place a signal amplification circuit board here to amplify the electrical signal, the amplified electrical signal is transmitted to the a/D converter 2, the a/D converter 2 is used to convert an analog signal into a digital signal recognizable by the single chip microcomputer 3, the signal converted by the a/D converter 2 is transmitted to the single chip microcomputer 3, the single chip microcomputer 3 will provide a signal to the buzzer or alarm lamp to make it generate alarm flash or sound, it should be noted that when there is no air leakage between the dry powder barrel body D and the dry powder barrel cover E, the pressure in the cavity 8 is the standard atmospheric pressure, if the pressure sensor 1 detects that the pressure in the cavity 8 is greater than the standard atmospheric pressure, the buzzer or the alarm lamp can give an alarm immediately to remind medical personnel, and the signal amplifying circuit belongs to the known technology and is not explained herein. The threaded connection pipe 10 and the air outlet pipe 80 are in threaded connection, so that the elastic sealing ring 8 is separated from related electronic elements and is changed into two parts, the elastic sealing ring 8 is conveniently sleeved between the dry powder barrel body D and the dry powder barrel cover E, and the end cover sealing sheet 81 is also made of an elastic material and can be sealed at the upper end of the dry powder barrel cover E.
