Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0039] Figure 1-2 It shows the composition structure of the absorption tank bypass device. The micro switch 18 is connected with the contact wheel 22 through the connection plate 21. When the machine is working normally, the absorption tank 20 and the support pipe 10 are in the vicinity image 3 At this time, the contact wheel 22 is not in contact with the support tube 10, the gas exhaled by the patient passes through the one-way valve, flows into channel 1 of the two-position three-way valve, and then flows into the absorption tank 20, after being purified by the absorption tank, it flows into the patient's inhalation end (see attached figure 1 ), when the operator needs to replace the absorption tank, the cam 1 is rotated to the attached position by turning the handle 16 Figure 5 At this ...

Abstract

The invention provides a tourill bypass device which is characterized in that when the tourill is needed to be replaced, during the rotating of a handle, electrical signals can be sent to a control circuit board through pressing a trolley wheel of a micro switch; a solenoid valve is controlled by the control circuit board; and an air channel of a two-position three-way valve is controlled by the control circuit board; the tourill is bypassed effectively in time; and the operation is convenient and timesaving. The tourill bypass device has the advantages that after the tourill is replaced, the handle is only needed to be rotated to the original position; the operation is simple and effective during the whole replacing process; and the seal effect of the air channels is good.

Description

technical field [0001] The invention relates to a circuit device, and more specifically, to a control technology of the gas circuit and its corresponding mechanical structure when the absorption tank is replaced in the circuit. Background technique [0002] The existing technology solves the problem that the control technology of the gas path when replacing the absorption tank in the circuit is purely mechanical. There are two main methods. One is to switch the gas path through the switch of the gas path when the absorption tank needs to be replaced, and then take the The lower absorption tank, the other is to use the bypass valve principle to switch the gas path. During the operation, the air circuit is directly changed through the pneumatic switch, and some are replaced after the operation is over. Since it is a manual operation switch, the operation is not very easy. [0003] The first solution to the gas circuit control technology principle when replacing the absorptio...
