The heat insulation frame 232 is movably arranged between the limit rod 223 and the pushing head 222, and an electric heating rod 233 is arranged in the heat insulation frame 232.

[0019] Working principle and workflow: When in use, the medical staff pulls the device to the patient's bedside through the mobile seat 12, and adjusts the frame seat 1 to a height that is convenient for operation through the adjustment rod 11, checks the connection between the connecting pipe 64 and the air extraction hole 51, takes a clean decompression tube mechanism 7, tightens the mounting nut 71 into the catheter screw hole 52, and folds the gastric tube 73 into the storage frame 53, so that the decompression head 74 is suspended in the air, and pays attention to keeping the decompression head 74 clean; Then, a clean partition-type drainage bag 3 is taken out, and the plug caps 33 in the air extraction head 31 and the connector 32 are removed respectively, so that the air extraction head 31 is inserted into the slot 55, and the connector 32 is rotated into the threaded groove 75 at the same time, so that the connecting hole 72 is connected with the connector 32, and then the lower end of the partition-type drainage bag 3 is inserted into the inner side of the symmetrical fixing clamp 4, and the electromagnetic switch 42 is started. The electromagnetic switch 42 makes the electromagnetic rod 41 electromagnetic, and the symmetrical electromagnetic rods 41 attract each other, clamping and fixing the partition-type drainage bag 3 therebetween, so as to prevent the partition-type drainage bag 3 from shaking and affecting the judgment of the sensor strip 216; Finally, the frame seat 1 with the separated drainage bag 3 installed is adjusted to a position lower than the bed through the adjusting rod 11, the gastric tube 73 is taken out from the storage frame 53, and the pressure reducing head 74 is inserted into the patient's mouth or nasal cavity. After the gastric tube 73 is fixed, the suction motor 61 is started. Before this, the medical staff can observe the extension and contraction amount of the telescopic push plate 62 through the observation window and compare it with the scale value. The extension and contraction amount of the telescopic push plate 62 can be adjusted according to the actual situation of the patient, thereby controlling the extraction force.

[0020] When the telescopic push plate 62 moves downward in the vacuum cylinder 63, the spring plate on the air outlet 65 blocks the air outlet 65, and the spring plate at the air inlet 66 opens under the action of air pressure to extract the gas in the partition type drainage bag 3, thereby generating negative pressure in the partition type drainage bag 3 to suck out the patient's stomach contents. When the telescopic push plate 62 moves upward in the vacuum cylinder 63, the spring plate at the air inlet 66 blocks the air inlet 66, and the spring plate at the air outlet 65 opens under the action of air pressure to discharge the gas in the vacuum cylinder 63. This cycle continuously extracts the patient's stomach contents with negative pressure to reduce the patient's gastrointestinal tract pressure.

[0021] During the extraction of the patient's gastric contents, the gastric contents extracted through the gastric tube 73 fall into the partition-type drainage bag 3, and are separated into solid and liquid by the filter layer 34. The filter layer 34 made of fiber filter cloth is convenient for separating the viscous solid-liquid mixture. The gastric fluid falls to the lower part of the partition-type drainage bag 3, and the viscous or solid objects are filtered out by the filter layer 34 and remain in the upper part of the filter layer 34. The accumulated gastric contents cause the partition-type drainage bag 3 to expand. When the bag wall of the partition-type drainage bag 3 touches the sensor strip 216, the extraction needs to be stopped immediately to avoid exceeding the capacity of the partition-type drainage bag 3. The induction strip 216 sends a signal, and the vacuum motor 61 stops immediately, blocking the generation of negative pressure in the partitioned drainage bag 3. At the same time, the first electric push rod 212 starts, and the electric heating rod 233 is powered on for preheating. The first electric push rod 212 pushes the fixed support block 213 to move toward the partitioned drainage bag 3, and the sliding mechanism 22 and the heat sealing mechanism 23 follow the movement until the symmetrical induction strips 216 squeeze the middle part of the partitioned drainage bag 3, isolating the filter layer 34 and the part above the filter layer 34 in the partitioned drainage bag 3 from the gastric fluid below. Then the motor 214 starts, pushing the threaded rod 215 to rotate, and Under the restriction of the limit rod 223, the connecting plate 221 drives the pushing head 222 to move downward, and the end of the pushing head 222 moves downward in contact with the bag wall of the partition type drainage bag 3, so that the bag walls on both sides of the partition type drainage bag 3 between the sensing strip 216 and the pushing head 222 are in close contact, and then the second electric push rod 231 is immediately started to push the insulation frame 232 to move until the symmetrical insulation frames 232 are against each other, and the electric heating rod 233 is in contact with the partition type drainage bag 3, so that the bag walls on both sides are heat-sealed to isolate the gastric fluid from the solid gastric contents, and then the electric heating rod 233 is reset, the first electric push rod 212 is reset, and the connecting plate 221 is reset.

[0022] During this process, the alarm 54 lights up to remind the medical staff that the separated drainage bag 3 needs to be replaced. The medical staff fixes and cuts off the gastric tube 73, then opens the air outlet 65 to release the air, turns off the electromagnetic switch 42, and the electromagnetic rod 41 loses its magnetism to release the separated drainage bag 3. Then, the connecting head 32 is rotated, and the suction head 31 is pulled out to remove the separated drainage bag 3. Finally, the plug caps 33 of the suction head 31 and the connecting head 32 are respectively plugged. If the patient still needs gastrointestinal decompression, a new separated drainage bag 3 can be installed and used again; otherwise, after taking out the gastric tube 73, unscrew the mounting nut 71, and when the next patient uses it, replace the new decompression tube mechanism 7 and the separated drainage bag 3. The operation is convenient and the work efficiency of medical staff is improved. The used separated drainage bag 3 can be directly sent to the laboratory. The separated drainage bag 3 separates the solid and liquid contents of the patient's stomach and seals them separately for subsequent testing.

[0023] It is worth noting that the adjustment of the pushing length of the telescopic push plate 62, the application of the induction strip 216, the application of the spring plate and the application of the electric heating rod 233 are all existing technologies and will not be described in detail here.
