Problems solved by technology

[0004] In the air supply system mentioned above, the air supply is only used as a backup solution. When the pressure value of the carbon dioxide high-pressure gas storage cylinder is less than a certain value, the carbon dioxide becomes air and contacts the human body, which reduces the comfort of the human body and is prone to flatulence; the pump drive circuit It only controls the opening and closing of the air pump, but cannot adjust the speed of the air pump, resulting in the air pressure cannot be adjusted

Embodiment 1

[0027] Such as figure 1 and figure 2 The shown endoscope water and air supply system includes a water and gas bottle 1, a main air pipe 3 and a water pipe 4 that merge into a water and air pipe 2 at one end, and the other end of the water pipe 4 is inserted into the liquid surface of the water and air bottle 1. On the main air pipe 3 The branch is connected with a bronchus 5, the other end of the bronchus 5 communicates with the water cylinder 1, the other end of the main air pipe 3 is connected with the air pipe 6 and the connecting pipe 7, the other end of the air pipe 6 is connected with an air pump 8, and the connecting pipe The other end of 7 is connected to a three-way solenoid valve 9, the air inlet of the three-way solenoid valve 9 is connected to a carbon dioxide pump 10, and the supply system also includes a control module for controlling the start and stop of the air pump 8 and the on-off of the three-way solenoid valve 9, The air pipe 6 is provided with an adjust...

Embodiment 2

[0040] The structural principle of this embodiment is basically the same as that of the first embodiment, except that a mechanical structure is used to adjust the flow rate in the air pipe. Specifically, the adjustment assembly includes valve one and valve two connected to the air pipe, valve one and valve two are connected in series, valve one is provided with handle one for adjusting the opening size of valve one, and rotating handle one can change the opening size of valve one The valve two is provided with a handle two for adjusting the opening size of the valve two, and the opening size of the valve two can be changed by rotating the handle two. The purpose of regulating the flow in the air pipe can be achieved by the joint action of valve one and valve two.

Abstract

The invention provides an endoscope water-air supply system, and belongs to the technical field of endoscopes. Through the endoscope water-air supply system, the problem that carbon dioxide and air are sent into a patient body simultaneously existing in an air supply system of an existing endoscope is solved. The endoscope water-air supply system comprises a water-air bottle, a main air pipe and awater pipe with one ends joint to be a water-air pipe, the other end of the water pipe is inserted into the liquid level of the water-air bottle, the main air pipe is connected with a branch air pipein a supported mode, the other end of the branch air pipe communicates with the water-air bottle, the other end of the main air pipe is connected with an air pipe and a three-way of a connecting pipe, the other end of the air pipe is connected with an air pump, the other end of the connecting pipe is connected with a three-way electromagnetic valve, an air inlet of the three-way electromagnetic valve is connected with a carbon dioxide pump, the endoscope water-air supply system further comprises a control module, the air pipe is provided with an adjusting assembly for adjusting air mass flowin the air pipe, and the adjusting assembly is connected with the control module. According to the endoscope water-air supply system, the operation safety and the operation effect are improved, the situation that the carbon dioxide and the air are sent into the patient body simultaneously is effectively avoided, and the endoscope water-air supply system has the advantages of wide range of application and the like.

Description

technical field [0001] The invention belongs to the technical field of endoscopes, and relates to an endoscope water and air supply system. Background technique [0002] The electronic endoscope cold light source device not only provides the light source for the endoscope, but also provides air supply and water supply functions. Since carbon dioxide gas can effectively reduce the flatulence of patients using endoscopes, many qualified hospitals currently use carbon dioxide as the gas source, and the air pump is only used as a backup solution. At present, the carbon dioxide gas source is connected to the mirror body, and the carbon dioxide trachea needs to be reinserted after each operation for a patient, which increases the workload of the doctor. At the same time, the carbon dioxide gas source pipeline is installed on the mirror body, which increases the The complexity of the mirror body increases the difficulty of disinfecting the mirror body. [0003] For this reason, a...
