[0023] like Figure 1-6The multifunctional negative pressure drainage device shown includes a drainage device body 1. An exhaust pipe 2 and a connecting pipe 3 are respectively installed at the top of the drainage device body 1. A first manual switch valve 4 and a second manual switch valve 5 are respectively installed on the exhaust pipe 2 and the connecting pipe 3. A filter 7 is installed inside the exhaust pipe 2. A first positioning component 6 is installed at one end of the filter 7 and is located on the side wall of the exhaust pipe 2. An annular mounting groove 9 is opened at the top of the connecting pipe 3. A drainage pipe 10 is installed inside the annular mounting groove 9. A second positioning component 11 is installed at one end of the drainage pipe 10 and is located on the side wall of the connecting pipe 3. A drain pipe 13 is installed at the bottom of the drainage device body 1. A third manual switch valve 14 and a flow meter 15 are respectively installed on the drain pipe 13. Several support feet 16 are evenly spaced around the bottom of the drainage device body 1. It should be noted that the first positioning component 6 facilitates the quick installation and removal of the filter 7 inside the exhaust pipe 2, and the second positioning component 11 facilitates the quick installation and removal of the drainage tube 10 inside the connecting pipe 3. A sealing gasket is provided in the annular mounting groove 9 and connected to the end of the drainage tube 10. The outer wall of the drainage device body 1 is made of transparent plastic and has scale lines engraved on the outer wall to observe the internal gastric fluid volume.

[0024] Specifically, the filter 7 includes a filter block positioned above a limiting ring 8, which is located at the connection between the main body 1 of the filter and the exhaust pipe 2. Activated carbon and a filter membrane are sequentially arranged inside the filter block from top to bottom. A positioning socket is located at the end of the filter block near the first positioning component 6, and the first positioning component 6 is housed within this socket. It should be noted that the filter block, in conjunction with the activated carbon and filter membrane, discharges excess gas from the main body 1 of the filter and removes odors, ensuring that the working environment after discharge is not polluted.

[0025] Specifically, the first positioning component 6 includes a mounting limiting tube, which is perpendicular to and communicates with the exhaust pipe 2. A first return spring is provided on the inner wall of the mounting limiting tube, and a first movable insert is provided on the first return spring. One end of the first movable insert is located in the positioning socket. It should be noted that by pulling the first movable insert away from the filter 7, the first return spring can automatically reset it, thus achieving the installation, positioning, and disassembly effects of the filter 7.

[0026] Specifically, the second positioning component 11 includes a horizontal tube, which is perpendicular to and communicates with the connecting tube 3. A second return spring is provided on the inner wall of the horizontal tube, and a second movable rod is provided on the second return spring. One end of the second movable rod is located in the auxiliary positioning socket 17, which is located on the side wall of the connecting end of the drainage tube 10. It should be noted that when the second movable rod is pulled away from the drainage tube 10, and the auxiliary positioning socket 17 on the drainage tube 10 reaches the designated position, releasing the second movable rod will allow it to automatically reset through the action of the second return spring, thus achieving the installation, positioning, and disassembly effects of the drainage tube 10.

[0027] Specifically, the output end of the drain pipe 13 is equipped with a threaded connection, and the input end of the drain pipe 13 is equipped with a filter screen 12. The exhaust pipe 2, connecting pipe 3, and drain pipe 13 are all detachably connected to the main body 1 of the drainage device by threads. It should be noted that the exhaust pipe 2, connecting pipe 3, and drain pipe 13 can all be replaced with the required diameter as needed, and maintenance is convenient. The drain pipe 13, together with the filter screen 12, ensures that the gastric fluid is free of particulate impurities during sampling, facilitating subsequent routine examination of the gastric fluid.

[0028] The working principle of this specific embodiment is as follows: First, the installation end of the drainage tube 10 connected to the gastric tube is placed in the annular installation groove 9. At this time, the second movable insert is pulled away from the drainage tube 10, and the auxiliary positioning insert 17 on the drainage tube 10 reaches the designated position. The second movable insert is released and reset by the action of the second reset spring, and then inserted into the auxiliary positioning insert 17, so that the drainage tube 10 is installed on the drainage device body 1.

[0029] When the patient needs to take oral medication as prescribed and gastrointestinal decompression needs to be paused, the drainage tube 10 can be closed by using the second manual switch valve 5. When gastrointestinal decompression needs to be resumed, the second manual switch valve 5 can be opened again.

[0030] When there is too much gas to be drawn and it needs to be vented, simply open the first manual switch valve 4 to allow the gas to pass through the filter 7 and the exhaust pipe 2. When the required filter 7 needs to be replaced, after removing the exhaust pipe 2 from the main body 1 of the gas drawer, pull the first movable insert rod away from the filter 7 to remove and install the filter 7 from the exhaust pipe 2.

[0031] When it is necessary to examine the patient's gastric fluid routine, connect the sampling bottle to the drain tube 13, and then drain the fluid through the third manual switch valve 14. At the same time, use the flow meter 15 to observe the drain volume to achieve the required sampling volume. After sampling is completed, the sampling bottle can be removed.

[0032] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
