Description

Technical Field

[0001] The invention relates to the field of anti-blocking gastrointestinal decompression devices, in particular to an anti-blocking gastrointestinal decompression device. Background Art

[0002] Patients with gastrointestinal obstruction and patients after gastrointestinal surgery need to have a gastric tube placed for gastrointestinal decompression.

[0003] Because there are contents in the gastrointestinal tract, traditional gastric tubes are easy to block the tube during use, and the expected treatment effect cannot be achieved. The tube can be left in place easily without increasing the patient's pain, and the tube will not be blocked frequently. Smooth gastrointestinal decompression can increase the patient's comfort.

[0004] Therefore, it is necessary to provide a new anti-blocking gastrointestinal decompression device to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a gastrointestinal decompression device with an anti-blocking function that is easy to peel off.

[0006] The anti-blocking gastrointestinal decompression device provided by the present invention comprises a gastrointestinal decompression tube, one end of the gastrointestinal decompression tube is connected to a first connector, a blockage clearing mechanism is arranged inside the gastrointestinal decompression tube, one end of the gastrointestinal decompression tube is connected to an absorption tube head, the blockage clearing mechanism is used to keep the gastrointestinal decompression tube unobstructed, one end of the first connector is screwed with a negative pressure bottle; the blockage clearing mechanism comprises a second connector, the interior of the second connector is screwed with a water bag, one end of the second connector is connected to an infusion tube, one end of the infusion tube passes through the outer wall of the gastrointestinal decompression tube and extends to the interior.

[0007] In order to achieve the effect of separating the gastrointestinal decompression tube from the inner tube, the present invention provides an anti-blocking gastrointestinal decompression device. Preferably, an inner tube is inserted into the gastrointestinal decompression tube, and one end of the infusion tube is connected to the interior of the inner tube.

[0008] In order to facilitate the limiting effect of the airbag strip, the present invention provides an anti-blocking gastrointestinal decompression device. Preferably, a connecting frame is connected to the outer side of the bottom of the inner tube, and the airbag strip is arranged inside the connecting frame.

[0009] In order to facilitate the inflating of the interior of the airbag strip and unfolding the absorption tube head, the present invention provides an anti-blocking gastrointestinal decompression device. Preferably, the gastrointestinal decompression tube is connected to an air inlet pipe, the air inlet end of the air inlet pipe is connected to a control valve, and the air outlet end of the air inlet pipe is connected to the air inlet end of the airbag strip.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Blockage clearing mechanism: When the gastrointestinal decompression tube is blocked, negative pressure is generated in the negative pressure bottle, and the liquid in the water bag is released by squeezing to flush away the gastrointestinal contents adsorbed on the inner tube, thereby increasing the gastrointestinal decompression effect. At the same time, air can be inflated into the air bag strip through the air inlet pipe, so that the air bag strip pushes open the absorption tube head, causing the absorption tube head to expand and expand the diameter of the absorption tube head, thereby reducing blockage.

[0020] In the specific implementation process, Figure 1 and Figure 2 As shown, an inner tube 7 is inserted into the gastrointestinal decompression tube 1 , and one end of the infusion tube 32 is connected to the interior of the inner tube 7 .

[0021] Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer side of the bottom of the inner tube 7 is connected with a connecting frame 8 , and the interior of the connecting frame 8 is provided with an airbag strip 9 .

[0022] It should be noted that the connection between the inner tube 7 and the gastrointestinal decompression tube 1 is made of a relatively hard medical plastic material, the connection between the inner tube 7 and the gastrointestinal decompression tube 1 is threaded, the connecting frame 8 and the inner tube 7 are an integral injection-molded part, the airbag strip 9 is embedded in the connecting frame 8, and is connected to one end of the air inlet pipe 5.

[0025] The working principle of the anti-blocking gastrointestinal decompression device provided by the present invention is as follows:

[0026] When in use, the end of the gastrointestinal decompression tube 1 provided with the absorption tube head 4 is inserted into the patient's body, and the absorption tube head 4 enters the stomach, and then one end of the gastrointestinal decompression tube 1 is installed with the negative pressure bottle 10, and the gastrointestinal contents in the patient's body are absorbed by the absorption tube head 4, and the gastrointestinal contents enter the inner tube 7 through the closed absorption tube head 4, and enter the negative pressure bottle 10 from the inner tube 7 through the first connector 2 for storage. When the absorption tube head 4 or the inner tube 7 of the gastrointestinal decompression tube 1 is blocked by the gastrointestinal contents, the water bag 33 can be installed at the second connector 31, and By squeezing the water bag 33, the liquid enters the inner tube 7 through the infusion tube 32, and the negative pressure generated by the negative pressure bottle 10 is used to flush away the gastrointestinal contents, thereby keeping the inner tube 7 unobstructed and avoiding the inner tube 7 from being blocked, thereby reducing the gastrointestinal decompression effect. In order to avoid the absorption tube head 4 having a small absorption aperture and being easily blocked, a syringe can be inserted into the air inlet end of the control valve 6, and then the control valve 6 can be opened to allow the gas to enter the interior of the airbag strip 9 through the air inlet pipe 5, causing the volume of the airbag strip 9 to expand. After the airbag strip 9 expands, the four fitted absorption tube heads 4 are unfolded to expand the absorption aperture of the absorption tube head 4.
