[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1 - Figure 5 In one embodiment of this application, a gastrointestinal decompression device includes a decompression device body 2 and a gastric tube body 4. The communication hole 24 of the decompression device body 2 is connected to the gastric tube body 4. The gastric tube body 4 is provided with an adjustment mechanism. The adjustment mechanism is used to adjust the height and communication state of the gastric tube body 4. The adjustment mechanism includes an adjustment component 10, a telescopic component 9 and a fixing clip 5. The two ends of the telescopic component 9 are respectively connected to the fixing clip 5 and the adjustment component 10. The fixing clip 5 is used to clamp onto a fixed object. The telescopic component 9 is used to adjust the height of the adjustment component 10. The adjustment component 10 is sleeved on the gastric tube body 4, and the adjustment component 10 is also used to control the communication state of the gastric tube body 4.

[0028] The adjustment assembly 10 includes an adjustment frame 11, a clamping plate 12, and a first fixing sleeve 28. The clamping plate 12 is located at one end of the gastric tube body 4. The clamping plate 12 is slidably connected to a sliding groove 13 on the adjustment frame 11 via the first fixing sleeve 28. The position of the clamping plate 12 on the sliding groove 13 is locked by a locking assembly. When the clamping plate 12 is in the communicating position, it is used to support the gastric tube body 4. When the clamping plate 12 is in the closed position, it is used to close the gastric tube body 4.

[0029] The telescopic assembly 9 includes a telescopic link 29 and a second fixed sleeve 33. One end of the telescopic link 29 is connected to the adjusting frame 11, and the other end of the telescopic link 29 slides against the second fixed sleeve 33. The end of the second fixed sleeve 33 away from the telescopic link 29 is connected to the fixing clamp 5.

[0030] In practical applications, the fixing clip 5 is clamped to the bed frame or bed sheet, so that the gastric tube body 4 can be made movable when the patient changes sleeping position or gets up, which improves the convenience of use. Then, the height of the gastric tube body 4 can be adjusted by adjusting the extension length of the telescopic connecting rod 29, so that the excrement in the stomach and intestines can be drained into the decompression device body 2. This provides convenience for the installation, use and disassembly of the gastric tube body 4, avoiding the need for medical staff to attach additional adhesive tape to the bed sheet and the gastric tube body 4 to lift the gastric tube body 4 to a certain height. However, this method of lifting the gastric tube body 4 is cumbersome and the height cannot be adjusted. In addition, the gastric tube body 4 is supported by the clamp 12 or closed by clamping the gastric tube body 4, which facilitates the operation of medical staff.

[0031] In this embodiment, the locking assembly includes a connecting shaft 26, a hinge rod 25, a locking rod 31, and a locking spring 32. One end of the connecting shaft 26, which has a locking groove, is rotatably connected to the adjusting frame 11, and the other end of the connecting shaft 26 is fixedly connected to the hinge rod 25. The end of the hinge rod 25 away from the connecting shaft 26 is hinged to the side of the negative pressure storage bag 23. The connecting shaft 26 has multiple locking grooves, and these multiple locking grooves are arranged circumferentially along the connecting shaft 26. One end of the locking rod 31 is positioned directly opposite the locking groove of the connecting shaft 26. The other end of the locking rod 31 is slidably connected to the adjusting frame 11, and the other end of the locking rod 31 is also connected to the adjusting frame 11 through the locking spring 32. When the clamping plate 12 is in the connected position or the closed position, the locking rod 31 is facing different locking slots. Under the elastic action of the locking spring 32, the locking rod 31 is inserted into the locking slot of the connecting shaft 26 to limit the circumferential movement of the connecting shaft 26, thereby limiting the position of the clamping plate 12 and ensuring the stability of supporting or closing the gastric tube body 4.

[0032] To facilitate the closure of the gastric tube body 4, in this embodiment, two clamping plates 12 are provided. The two clamping plates 12 are located on both sides of the gastric tube body 4, and are respectively hinged to both ends of the hinge rod 25. A connecting shaft 26 is located between the two clamping plates 12, and the end of the connecting shaft 26 away from the hinge rod 25 extends to the outside of the adjusting frame 11 and is fixedly connected to the handle 14. Thus, by reversing the connecting shaft 26, the clamping plates 12 can be driven to clamp or release the gastric tube body 4.

[0033] To facilitate fixing the extension length of the telescopic link 29, in this embodiment, the telescopic assembly 9 further includes a screw 27. One end of the screw 27 passes through a threaded groove formed in the shell wall of the second fixed sleeve 33 and extends into the second fixed sleeve 33. The screw 27 is threadedly connected to the threaded groove, and the other end of the screw 27 is located outside the second fixed sleeve 33. The screw 27 is used to fix the extension length of the telescopic link 29 by abutting against it, thereby achieving stability in adjusting the height of the gastric tube body 4.

[0034] To facilitate observation of gastrointestinal excrement, in this embodiment, an observation tube 3 is provided at the connection between the gastric tube body 4 and the decompression device body 2.

[0035] In this embodiment, the decompression device body 2 includes a separation sleeve 21, a filter sleeve 22, and a negative pressure storage bag 23 arranged sequentially. The filter sleeve 22 is detachably connected to the separation sleeve 21, and the filter sleeve 22 is fixedly connected to the negative pressure storage bag 23. A collection area 17 is provided inside the separation sleeve 21. The connecting hole 24 at the top of the collection area 17 communicates with the gastric tube body 4, and the bottom of the collection area 17 communicates with the negative pressure storage bag 23 through a filter hole 20 on the filter sleeve 22. The detachable connection between the filter sleeve 22 and the separation sleeve 21 can be achieved through snap-fit ​​connection, threaded connection, etc., which is not limited in this embodiment.

[0036] To facilitate the collection of solid waste and to separate and process solid and liquid waste, in this embodiment, the filter sleeve 22 is further provided with a solid collection area 19. The solid collection area 19 is connected to the collection area 17 through the discharge hole 18. The solid collection area 19 and the filter hole 20 are located at opposite ends of the collection area 17, and the filter hole 20 is positioned directly opposite the connecting hole 24. The collection area 17 is also provided with a scraper 16, which is installed at the output end of the motor 15. The motor 15 is installed on the separation sleeve 21. The scraper 16 is used to scrape the solids at the filter hole 20 into the solid collection area 19.

[0037] To facilitate the storage of the pressure reducer body 2, the pressure reducer body 2 is installed in a storage box 1. The storage box 1 is provided with a hanging rod 30 for hanging on a bed frame. The storage box 1 is provided with a base plate 6 for supporting the bottom of the pressure reducer body 2. The side of the base plate 6 away from the pressure reducer body 2 is connected to the storage box 1 by a connecting spring 7. The top of the separation sleeve 21 is also provided with a connecting hole 24 for hanging on the top of the pressure reducer body 2. The storage box 1 is also provided with a support frame 8 for supporting the filter sleeve 22.

[0038] This allows the hanging rod 30 to be hung on a bed frame or other fixed object. When it is necessary to replace the new filter sleeve 22 and negative pressure storage bag 23, first turn the handle 14 to move the clamp 12 to the closed position, so that the two clamps 12 close the gastric tube body 4. Then, take out the separation sleeve 21, filter sleeve 22 and negative pressure storage bag 23 from the storage box 1 through the connecting hole 24. Then, remove the filter sleeve 22 from the separation sleeve 21, and then install the new filter sleeve 22 and negative pressure storage bag 23 on the separation sleeve 21 to achieve the replacement function.
