[0001] This invention belongs to the field of medical device technology, specifically a pediatric gastrointestinal decompression device for clinical use in digestive diseases. Background Technology

[0002] The pediatric gastrointestinal decompression device is a medical device used to decompress the gastrointestinal tract of pediatric patients. Its main purpose is to relieve excessive distension or pressure in the gastrointestinal tract by removing gas, liquid or food residue, thereby promoting the functional recovery of the digestive tract.

[0003] Traditional gastrointestinal decompression devices typically have one air outlet and one air inlet. However, due to the young age of children, they cannot accurately express discomfort during gastrointestinal decompression, leading to crying, coughing, and changes in body position. This causes violent and rapid fluctuations in abdominal pressure, which can easily result in excessive decompression causing mucosal damage or insufficient decompression leading to poor results. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem mentioned in the background art that children cannot accurately express their discomfort, leading to crying, coughing, and changes in body position, resulting in severe and rapid fluctuations in abdominal pressure, which can easily cause excessive decompression leading to mucosal damage or insufficient decompression leading to poor results, this invention provides a pediatric gastrointestinal decompression device for clinical use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pediatric gastrointestinal decompression device for clinical use, comprising a fixed base plate, wherein a collection assembly and a second collection cylinder are sequentially fixedly installed on the top of the fixed base plate, and a limiting component is fixedly installed between the collection assembly and the second collection cylinder. The collection assembly includes a housing, wherein a first collection cylinder is fixedly installed at the bottom of the inner cavity of the housing, a first connecting pipe is fixedly installed on one side of the first collection cylinder, an outlet pipe and an inlet pipe unit are fixedly installed on the top surface of the first collection cylinder, and the outlet pipe and inlet pipe unit are connected to the first collection cylinder, a connecting rod is fixedly installed on the top surface of the first collection cylinder, and a pressure relief assembly is fixedly installed in the middle of the first collection cylinder.

[0006] Preferably, the air intake pipe unit includes an air intake pipe body, which is fixedly connected to and communicates with a collection cylinder, and a rotating component is provided at the upper end of the air intake pipe body.

[0007] Preferably, the pressure relief assembly includes a fixing member, which is fixedly connected to the housing. A connecting pipe is fixedly connected to the outer wall of the first collecting cylinder. A piston is movably connected to the end of the connecting pipe, and a spring is fixedly connected between the piston and the fixing member.

[0008] Preferably, the rotating component includes a rotating rod, a hand handle is fixedly installed on one side of the rotating rod, a telescopic cylinder is fixedly installed on the top surface of the fixed base plate, a fixing block is fixedly installed in the middle of the telescopic cylinder, and a spring is fixedly installed between the telescopic cylinder and the fixed base plate.

[0009] Preferably, the end of the rotating rod is provided with a sphere, and the sphere is hollow. The end of the hand handle away from the rotating rod is provided with a groove and is movably connected to the telescopic cylinder.

[0010] Preferably, the telescopic cylinder is composed of two rectangular blocks, and the length of the upper rectangular block is less than the length of the lower rectangular block. A sliding groove is provided on one side of the lower rectangular block and is movably connected to the fixed block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention, through the combination of a piston and a connecting tube, addresses the issue that children's gastrointestinal walls are thin during decompression, and negative pressure can cause discomfort. When medical staff or accompanying parents observe that the child is crying violently or is uncomfortable, they can pull the piston to release the blockage between the piston and the connecting tube, allowing for rapid decompression of the collection cylinder and reducing the pressure in the gastrointestinal tract. This avoids situations where there are severe and rapid fluctuations in abdominal pressure, leading to excessive decompression causing mucosal damage or insufficient decompression resulting in poor efficacy.

[0017] This invention, through the combination of structures such as collection cylinder one and collection cylinder two, allows the gastrointestinal tract to accumulate a large amount of fluid and gas when collection cylinder one contains a large amount of fluid and gas. The fluid and gas then enter collection cylinder two through connecting tube one. Collection cylinder two acts as a buffer and liquid collection bottle, which helps to release gastrointestinal gas or liquid smoothly and gradually, avoiding excessive stretching or damage to the gastrointestinal wall caused by excessively rapid discharge.

[0025] 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.

[0026] like Figures 1 to 6As shown, this invention provides a pediatric gastrointestinal decompression device for clinical use, comprising a fixed base plate 1. A collection assembly 2 and a second collection cylinder 4 are sequentially fixedly mounted on the top of the fixed base plate 1. A limiting member 3 is fixedly installed between the collection assembly 2 and the second collection cylinder 4. The collection assembly 2 includes a housing 21. A first collection cylinder 22 is fixedly mounted at the bottom of the inner cavity of the housing 21. A first connecting pipe 23 is fixedly mounted on one side of the first collection cylinder 22. An outlet pipe 24 and an inlet pipe unit 25 are fixedly mounted on the top surface of the first collection cylinder 22, and the outlet pipe 24 and the inlet pipe unit 25 are connected to the first collection cylinder 22. The top surface of the first collection cylinder 22 is fixed... A connecting rod 26 is installed, and a pressure relief assembly 27 is fixedly installed in the middle of the first collection cylinder 22. The air intake pipe unit 25 includes an air intake pipe body 251, which is fixedly connected to and communicates with the first collection cylinder 22. A rotating part 252 is provided at the upper end of the air intake pipe body 251. The pressure relief assembly 27 includes a fixing part 271, which is fixedly connected to the housing 21. A connecting pipe 272 is fixedly connected to the outer wall of the first collection cylinder 22. A piston 273 is movably connected to the end of the connecting pipe 272. A spring 274 is fixedly connected between the piston 273 and the fixing part 271.

[0027] Using the above solution: Through the cooperation of the intake pipe unit 25 and the pressure relief assembly 27, before use, rotate the rotating part 252 to prevent the rotating part 252 from communicating with the intake pipe body 251, fix the rotating part 252, hold the connecting rod 26 and press down on the connecting rod 26. The connecting rod 26 drives the first collection cylinder 22 to move downward. When the connecting rod 26 drives the first collection cylinder 22 to retract, the connecting pipe 272 and the connecting pipe 23 in the housing 21 have sufficient length for the first collection cylinder 22 to retract. Gas in the collecting cylinder 22 is discharged from the outlet pipe 24. When the collecting cylinder 22 is compressed to its minimum, the switch on the outer wall of the outlet pipe 24 is closed, connecting the gastric tube to the inlet pipe body 251. After connection, the rotating component 252 is rotated, connecting the rotating component 252 to the inlet pipe body 251 and the collecting cylinder 22. The tension spring in the collecting cylinder 22 gradually unfolds, expanding the volume of the cavity in the collecting cylinder 22 and creating negative pressure. This allows the gastric tube to absorb the accumulated fluid and gas in the patient's gastrointestinal tract. The fluid and gas in the gastrointestinal tract are collected in collection cylinder 1, 22. When there is a significant amount of fluid and gas in collection cylinder 1, 22, the fluid and gas enter collection cylinder 2, 4 through connecting tube 1, 23. Collection cylinder 2, 4 acts as a buffer and liquid collection bottle. The buffer helps to release gas or liquid from the gastrointestinal tract smoothly and gradually, avoiding excessive stretching or damage to the gastrointestinal wall caused by rapid discharge. During gastrointestinal decompression, children's gastrointestinal walls are thin, and negative pressure can cause discomfort. When medical staff or accompanying parents observe that the child is crying violently or is uncomfortable, they should pull the piston. 273. The piston 273 is released from the blockage of the connecting tube 272, and the collecting tube 22 is quickly depressurized to reduce the pressure in the gastrointestinal tract. This avoids the situation where the abdominal pressure fluctuates violently and rapidly, causing excessive depressurization that could lead to mucosal damage or insufficient depressurization that could result in poor effects. After the rapid depressurization is completed, the spring 274 drives the piston 273 to return to its original position, causing the piston 273 to block the connecting tube 272, so that the gastrointestinal tract can be depressurized again next time. When the child stops crying, the above operation is repeated to depressurize the gastrointestinal tract.

[0028] like Figures 4 to 6 As shown, the rotating component 252 includes a rotating rod 2521, a handheld lever 2522 fixedly installed on one side of the rotating rod 2521, a telescopic cylinder 2523 fixedly installed on the top surface of the fixed base plate 1, a fixed block 2525 fixedly installed in the middle of the telescopic cylinder 2523, a spring 2524 fixedly installed between the telescopic cylinder 2523 and the fixed base plate 1, a sphere is provided at the end of the rotating rod 2521, and the sphere is hollow. The end of the handheld lever 2522 away from the rotating rod 2521 is provided with a groove and is movably connected to the telescopic cylinder 2523. The telescopic cylinder 2523 is composed of two rectangular blocks, and the length of the upper rectangular block is less than the length of the lower rectangular block. A sliding groove is provided on one side of the lower rectangular block and is movably connected to the fixed block 2525.

[0029] Using the above method: With the cooperation of the rotating rod 2521 and the handheld rod 2522, when the collecting cylinder 22 is compressed to its lowest point, the holding block 2525 is pulled downwards to disengage the rectangular block at the upper end of the telescopic cylinder 2523, thus releasing the telescopic cylinder 2523 from the groove of the rotating rod 2521. Then, the handheld rod 2522 is rotated, causing the rotating rod 2521 to rotate. After rotating 90 degrees, the rotation stops, the fixing block 2525 is released, and the spring 2524 causes the rectangular block at the upper end of the telescopic cylinder 2523 to reset, causing the telescopic cylinder 2523 to engage with the groove of the rotating rod 2521, thereby collecting the materials. The gastric tube, the inlet tube body 251, and the collection cylinder 22 are connected to absorb the accumulated fluid and gas in the gastrointestinal tract. The spherical and hollow design of the rotating rod 2521 allows it to be quickly connected or disconnected from the inlet tube body 251 and the collection cylinder 22. The design of the two rectangular blocks of the telescopic cylinder 2523 allows the upper rectangular block to move within the lower rectangular block. The design of the sliding groove of the lower rectangular block limits the upper rectangular block and the fixed block 2525 of the telescopic cylinder 2523 when the fixed block 2525 moves the upper rectangular block of the telescopic cylinder 2523, making it more stable during movement.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the connecting rod 26 is movably connected to the fixed base plate 1. A hook is provided at the upper end of the connecting rod 26, and the hook is movably connected to the connecting rod 26. A check valve is provided on the outer wall of the connecting pipe 23. The collecting cylinder 4 is connected to the connecting pipe 23.

[0031] The above scheme is adopted as follows: Through the cooperation of connecting rod 26 and fixed base plate 1, connecting rod 26 and fixed base plate 1 are movably connected. When pressing connecting rod 26 to drive collection cylinder 22 downward, fixed base plate 1 limits connecting rod 26, making connecting rod 26 more stable when moving. The design of hook at the upper end of connecting rod 26 allows the device to be suspended at the patient's bedside or at the IV drip site. Fixed base plate 1 makes the device more stable when placed on a table. Connecting rod 26 and hook are movably connected, and hook can rotate on connecting rod 26, making suspension more convenient. The design of check valve on the outer wall of connecting tube 23 prevents the backflow of accumulated liquid and gas in collection cylinder 24 into collection cylinder 22, causing infection. A vent is provided on one side of collection cylinder 24 to discharge the collected liquid and gas. The design of collection cylinder 24 being connected to connecting tube 23 can better guide the accumulated liquid and gas in collection cylinder 22 to collection cylinder 24, providing a temporary buffering effect for collection cylinder 22.

[0032] like Figure 1 , Figure 4As shown, the collecting component 2, collecting cylinder 1 22 and collecting cylinder 2 4 are all transparent. The outer walls of collecting component 2 and collecting cylinder 2 4 are provided with scale lines. One side of spring 274 is provided with a groove. Piston 273 is made of rubber. The inner cavity of collecting cylinder 1 22 is provided with a tension spring.

[0033] The above-mentioned solution utilizes the design of collecting component 2 and collecting cylinder 22. The transparent design allows medical staff to directly observe changes in the liquid or gas within the gastrointestinal decompression device. This enables immediate identification of the liquid's color, volume, and properties, aiding in monitoring the patient's condition. It also makes it easier for medical staff to detect blockages, leaks, or other malfunctions, thereby reducing complications caused by equipment problems. The scale design allows for precise quantification of the collected liquid volume, facilitating the tracking and recording of the gastrointestinal decompression effect. Regular liquid volume recording helps assess the patient's recovery, such as determining whether the gastrointestinal tract has begun to return to normal function, assisting doctors in assessing treatment effectiveness and further adjusting treatment plans. (Spring 27) The design of the four grooves, specifically the groove on spring 274, allows for rapid activation of spring 274 when the child is observed to be crying violently or experiencing discomfort. This activates piston 273 to release the blockage in connecting tube 272, enabling rapid pressure relief. The rubber material of piston 273 ensures a tight seal against the sealing surface, forming an effective sealing barrier to prevent liquid or gas leakage. It exhibits good biocompatibility and prevents contamination of medications or liquids. Furthermore, it is cost-effective and suitable for large-scale production and use. The tension spring design within the collecting cylinder 22 allows it to expand when connected to the gastrointestinal tract, creating negative pressure within the cylinder and absorbing accumulated water and gas from the patient's gastrointestinal tract.
