Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a neonatal gastrointestinal decompression device. Background Technology

[0002] Newborns often experience symptoms such as bloating and gastric retention due to their physiological characteristics and medical conditions. Gastrointestinal decompression, as an important treatment method, can significantly improve these symptoms and promote the recovery of gastrointestinal function by reducing the pressure inside the gastrointestinal tract. It is especially indispensable for treating serious conditions such as gastrointestinal obstruction and intestinal perforation.

[0003] In current medical practice, neonatal gastrointestinal decompression is typically performed using adult gastrointestinal decompression devices. However, adult gastrointestinal decompression devices often have drawbacks, such as large size, rigid materials, and high negative pressure. First, their large size makes them difficult to place properly in confined spaces like neonatal incubators. Second, their rigid materials can easily cause discomfort to the infant, and even lead to skin or mucous membrane damage. Furthermore, the high negative pressure of adult gastrointestinal decompression devices can easily cause gastrointestinal mucosal damage and bleeding in newborns with prolonged use. Finally, because they are adult gastrointestinal decompression devices, the methods for measuring drainage fluid are not applicable to newborns. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small, soft, and adjustable negative pressure gastrointestinal decompression device suitable for newborns.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: A neonatal gastrointestinal decompression device includes a gastric tube, a protective tube, an adapter, a connecting tube, a drainage bottle, a fixed base, and a negative pressure controller. The protective tube and the gastric tube are an integral structure. The protective tube includes an inner tube, an outer tube, a separator, and a return spring. The inner tube runs vertically through the gastric tube and communicates with it. The separator is located inside the inner tube and communicates with the gastric tube. The return spring is sleeved on the inner tube. The outer tube is sleeved on the top of the inner tube to seal it, and the bottom of the outer tube is connected to the return spring. The gastric tube includes a tube body and a ball-shaped probe. The tube body and the ball-shaped probe are an integral structure. Its other end is fixed to the stopper of the drainage bottle through the adapter. One end of the connecting tube is fixed to the stopper of the drainage bottle, and the other end is fixedly connected to the negative pressure controller. The negative pressure controller and the drainage bottle are both fixedly connected to the fixed base.

[0006] Preferably, the protective tube includes an inner tube, an outer tube, a separator, and a return spring. Both the inner and outer tubes have vent holes on their walls. The return spring is sleeved on the inner tube, with one end fixedly connected to the inner tube and the other end fixedly connected to the outer tube. When the return spring is in its natural state, the vent holes on the inner and outer tubes are misaligned. When the negative pressure inside the tube is too high, the outer tube is attracted and moves downward, causing the return spring to contract. The vent holes on the outer and inner tubes will gradually overlap, preventing the negative pressure inside the tube from continuing to increase.

[0007] Preferably, the gastric tube includes a tube body and a bulbous probe. Both the tube body and the bulbous probe are made of transparent soft polyurethane material, which has good flexibility. The outer wall of the gastric tube is provided with graduation lines to facilitate observation of the length of the gastric tube entering the newborn's body. The entire gastric tube is a sterile disposable instrument.

[0008] Preferably, the adapter includes a fixing tube and a valve, the valve being disposed outside the fixing tube, the fixing tube being fixed through and fixed to the stopper of the drainage bottle, and the port of the fixing tube outside the drainage bottle being connected to the gastric tube.

[0009] Preferably, the fixed base includes a base plate, a fixed column, a limiting plate, a fixing clip, and an anti-slip pad. The fixed column and the base plate are an integral structure. The fixed column is located in the center of the base plate. The limiting plate is located on the base plate close to the fixed column and is sized to fix the negative pressure controller. The fixing clip is located on the side of the fixed column and is sized to fix the drainage bottle. After fixing the negative pressure controller and the drainage bottle, the fixed column is located between them, so that the two are located on the base plate on both sides of the fixed column. The anti-slip pad is fixedly connected to the bottom of the base plate.

[0010] Preferably, the drainage bottle includes a stopper and a bottle body. The bottle body is a transparent rigid structure with scale lines on its outer surface. The stopper has two holes for fixing two adapters.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) The gastric tube is equipped with a protective tube to avoid excessive negative pressure in the tube, which may affect the newborn; (2) The gastric tube is made of soft material and the port at one end is designed as a ball probe to reduce damage to the newborn's esophagus during insertion. The surface is equipped with scale lines to facilitate the determination of the insertion length during insertion; (3) The gastric tube and drainage bottle are both made of transparent material to facilitate the doctor's observation of the aspirated substance; (4) The negative pressure controller can easily adjust the negative pressure in the tube as an aspiration device. The entire gastrointestinal decompression device has a simple structure, so it is small in size and easy to use. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Figure 1 As shown, a neonatal gastrointestinal decompression device includes a gastric tube 1, a protective tube 2, an adapter 3, a connecting tube 4, a drainage bottle 5, a negative pressure controller 6, and a fixed base 7. The protective tube 2 and the gastric tube 1 are an integral structure. The protective tube 2 includes an inner tube 210, an outer tube 220, a separating mesh 230, and a return spring 240. The return spring 240 is sleeved on the inner tube 210, and the outer tube 220 is sleeved on the top of the inner tube 210 to seal it, and the bottom of the outer tube 220 is connected to the return spring 240. One end of the gastric tube 1 is inserted into the fixed tube 310 of the adapter 3, and one end of the connecting tube 4 is inserted into the fixed tube 310 of another adapter 3. The two fixed tubes 310 are inserted into the bottle stopper 510 of the drainage bottle 5. The other end of the connecting tube 4 is connected to the negative pressure controller 6, which is fixed in a limiting plate 730. The drainage bottle 5 is fixed on a fixing clamp 740.

[0018] like Figure 2As shown, the protective tube 2 includes an inner tube 210, an outer tube 220, a separator 230, and a return spring 240. The separator 230 is located inside the inner tube 210 and communicates with the gastric tube 1, reducing the amount of aspirated material entering the tube. The inner tube 210 and the outer tube 220 are respectively provided with vent holes 211 and 221 on their walls. The return spring 240 is sleeved on the inner tube 210, with one end fixedly connected to the inner tube 210 and the other end connected to the outer tube. 220 is fixedly connected. When the return spring 240 is in its natural state, the vent holes 211 on the inner tube 210 and 221 on the outer tube 220 are misaligned. When the negative pressure inside the gastric tube 1 is too high, the outer tube 220 is attracted and moves downward, causing the return spring 240 to contract. The vent holes 211 and 221 will gradually overlap, allowing external gas to enter the tube body through the vent holes 211 and 221, preventing the negative pressure inside the tube from continuing to increase.

[0019] like Figure 3 As shown, the drainage bottle 5 includes a stopper 510 and a bottle body 520. The bottle body 520 is a transparent rigid structure with graduation lines on its outer surface. This design facilitates the doctor's observation of the aspirated material. The stopper 510 has two holes for fixing two adapters 3. Due to the siphon principle, the length of the fixing tube 310 connected to the gastric tube 1 inside the drainage bottle 5 is longer. The adapter 3 includes a fixing tube 310 and a valve 320. The valve 320 is located on the outside of the fixing tube 310. The fixing tube 310 passes through and is fixed to the stopper 510 of the drainage bottle 5. If the drainage bottle 5 needs to be removed and replaced, the valve 320 can be closed and the stopper 510 can be removed to replace the new bottle body 520.

[0020] like Figure 4 The fixed base 7 includes a base plate 710, a fixing post 720, a limiting plate 730, a fixing clip 740, and an anti-slip pad 750. The fixing post 720 and the base plate 710 are an integral structure. The fixing post 720 is located in the center of the base plate 710. The limiting plate 730 is located on the base plate 710 close to the fixing post 720 and is sized to fix the negative pressure controller 6. The fixing clip 740 is located on the side of the fixing post 720 and is sized to fix the drainage bottle 5. After fixing the negative pressure controller 6 and the drainage bottle 5, the fixing post 720 is located between them, so that the two are located on the base plate 710 on both sides of the fixing post 720. The anti-slip pad 750 is fixedly connected to the bottom of the base plate 710. Therefore, the overall size of the pressure reducer is small and convenient to place.

[0021] like Figure 5As shown, the gastric tube 1 includes a tube body 110 and a ball probe 120. The tube body 110 and the ball probe 120 are an integral structure. The surface of the tube body 110 is provided with scale lines to facilitate observation of the length of the gastric tube entering the newborn's body. The ball probe 120, made of transparent soft polyurethane material, reduces the damage to the newborn during insertion.

[0022] Instructions for use: After placing the installed gastrointestinal decompression device in a suitable position, insert the gastric tube 1 into the newborn's body. Determine the insertion length using the scale lines on the tube body 110. Operate the negative pressure controller 6 to generate a suitable negative pressure. The negative pressure in the drainage bottle 5 will then draw gas or stomach contents from the gastric tube 1. The stomach contents will flow directly into the drainage bottle 5, while the gas will be drawn away by the negative pressure controller 6. If the drainage bottle 5 needs to be removed and replaced, close the valve 320 and remove the bottle stopper 510 to replace the new bottle body 520. After the suction is complete, remove the gastric tube 1 and close the negative pressure controller 6. If the negative pressure in the gastric tube 1 is too high, the outer tube 220 of the protective tube 2 will be drawn down, causing the return spring 240 to contract. The vent holes 211 and 221 will gradually overlap, allowing external gas to enter the tube body through the vent holes 211 and 221, preventing the negative pressure in the tube body from continuing to increase.

[0023] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
