Technical Field

[0001] The present invention relates to the technical field of medical devices and supplies, and in particular to a multi-purpose gastrostomy tube with a gastric retention monitoring function. Background Art

[0002] While currently available gastrostomy tubes can provide basic gastrointestinal nutrition, a common problem is the lack of an effective mechanism for monitoring gastric retention, preventing physicians from providing real-time information on gastric retention to support treatment adjustments. Traditional gastrostomy tubes are typically fixed using a simple external fixation device with a tube made of silicone or other biocompatible materials. To address unstable fixation, some tubes have been enhanced with adhesive flaps or external gaskets made of softer materials. Monitoring gastric contents primarily relies on regular manual aspiration. However, these measures still have high failure rates and inconveniences. On the one hand, traditional gastrostomy tubes lack the ability to monitor intragastric pressure, making it difficult for physicians to obtain real-time information on gastric retention and adjust treatment plans in a timely manner, limiting the advancement of precision medicine. On the other hand, routine maintenance presents significant challenges, such as potential leakage and infection, or tube dislodgement due to improper fixation, which undoubtedly increases patient suffering.

[0014] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0015] The present invention provides a multi-purpose gastrostomy tube with gastric retention monitoring function, see Figure 1, including: a gastrostomy tube body 1, a fistula leak-proof strip 2, an externally fixed movable chassis 3 and an externally fixed film 4; the gastrostomy tube body 1 includes a feeding tube 11 and a water injection tube 12, the feeding tube 11 and the water injection tube 12 are connected through the tube wall, one end of the water injection tube 12 for extending into the body is connected to an internally fixed water injection balloon 5, the other end of the water injection tube 12 is provided with a water injection port 121, the water injection port 121 is connected to a water injection port cover 122, the water injection port cover 122 matches the water injection port 121, and the water injection port cover 122 is used to close the water injection port 121; a piston assembly 6 is connected to the water injection tube 12, the piston assembly 6 includes a piston 61, a piston cylinder 62 and a manual rod 63, the piston cylinder 62 is communicated with the interior of the water injection tube 12, the piston 61 matches the inner wall of the piston cylinder 62, and the piston 61 is under the action of pressure It moves axially along the piston cylinder 62, and a scale is provided on the piston cylinder 62. The scale is used to indicate the moving position of the piston 61 in the piston cylinder 62, thereby reflecting the change in the gastric retention amount; both ends of the piston cylinder 62 are provided with a limit member 621, and the limit member 621 is used to prevent the piston 61 from sliding out of the piston cylinder 62. The piston 61 matches the manual rod 63, and the manual rod 63 is used to manually adjust the position of the piston 61 in the piston cylinder 62; the fistula leakage-proof strip 2 is used to be pasted at the fistula opening to prevent leakage, and the fistula leakage-proof strip 2 is filled with silver ion dressing or antibacterial ointment; the external fixed movable chassis 3 is mounted on the gastrostomy tube body 1, and the external fixed movable chassis 3 is used to fix the part of the gastrostomy tube body 1 left outside the body, and the external fixed film 4 is used to stick and fix the part of the gastrostomy tube body 1 left outside the body.

[0016] Specifically, gastrostomy tubes are mainly suitable for gastrointestinal nutritional support and care for patients who cannot be fed orally, and are especially suitable for people such as patients with head and neck cancer who need long-term nutritional supply through gastrostomy. After a strict disinfection procedure, first slowly insert the end of the feeding tube 11 that enters the body and the internal fixed water injection balloon 5 into the predetermined position through the fistula opening, and then inject an appropriate amount of clean water or saline through the water injection port 121 to expand the internal fixed water injection balloon 5 to form a stable supporting force; adjust the piston 61 to the initial position using the manual rod 63, and use the water injection port cover 122 to cover the water injection port 121 to prevent the liquid in the water injection tube 12 from flowing out; gently straighten the gastrostomy tube body 1 to ensure that the pipeline is stable and does not slip, and place the fistula opening leak-proof strip 2 close to the edge of the fistula opening, and then adjust the shape along the skin contour until it fits perfectly; attach the external fixed movable chassis 3 to the appropriate position of the abdomen, and apply light pressure to allow it to fully contact the skin; then lay a layer of external fixed film 4 to ensure that the whole is flat and seamless, and use medical tape or other adhesive materials to stick and fix the piston cylinder and other positions. When the patient's gastric cavity pressure increases, the internal fixed water injection balloon 5 is squeezed and becomes smaller, and the liquid in the internal fixed water injection balloon 5 will flow to the water injection pipe 12. The piston 61 will be under pressure and move in the piston cylinder 62 toward the end away from the water injection pipe body. When the gastric cavity pressure decreases, the piston 61 will move toward the end close to the water injection pipe body under atmospheric pressure, and the internal fixed water injection balloon 5 will become larger; the gastric retention situation can be monitored by observing the position of the piston 61 on the piston cylinder 62; the piston cylinder 62 is made of transparent material for easy observation, and a scale is provided on the outer wall of the piston cylinder 62, and different scale intervals correspond to different color bars. According to literature review and clinical work, the color bar is corresponding to the classification of gastric retention amount (green for <200ml, yellow for 200-500ml, and red for >500ml). According to the classification, the doctor can adjust the feeding plan and drug synergistic treatment. Medical staff or family members can understand the specific gastric retention level by observing the color on the piston cylinder 62 (less than 200 ml is green, indicating normal, between 200 and 500 ml is yellow, reminding that attention is needed, and more than 500 ml is red, indicating a serious warning), and then take corresponding measures such as adjusting the speed of liquid food intake, increasing or decreasing the dosage of medicine, etc.

[0017] The internal fixation water-injected balloon 5 is made of medical silicone rubber material with excellent elasticity and stability, which can adapt to the anatomical differences of different patients; the gastrostomy tube body 1 is made of a high-molecular polymer material, which is corrosion-resistant and not prone to causing foreign body reactions. The stoma leak-proof strip 2 is set around the stoma to ensure a tight fit and effectively prevent liquid leakage. The stoma leak-proof strip 2 is filled with silver ion dressing or antibacterial ointment. The addition of silver ion dressing or antibacterial ointment reduces the risk of infection and significantly reduces the probability of various complications that may be caused, including leakage, infection and skin damage, thereby improving the patient's user experience and safety. The external fixation removable chassis 3 adopts a suction cup type and can be repeatedly adhered to the skin. The external fixation film 4 is made of a composite TPU film with good waterproof properties. The surface treatment process makes it both breathable and firm. The external fixation film 4 covers the exposed part, and the user can flexibly adjust the fixed position according to their own needs.

[0018] The unique anti-infection and plasticity stoma leak-proof strip 2 contains silver ion dressing or anti-infection ointment strip, which can effectively prevent skin infection at the stoma and prevent leakage, improve the patient's comfort and reduce the occurrence of complications; and the cooperation of the internal fixation water injection balloon 5 and the piston assembly 6 can dynamically monitor the gastric retention volume, assist doctors in formulating personalized feeding plans, dynamically adjust the feeding plan of gastrostomy patients, and facilitate the patient's nutritional management at home; in addition, under the joint action of the stoma leak-proof strip 2 and the waterproof external fixation film 4, leakage will not occur even if the patient is in an active state.

[0019] Furthermore, the diameter of the feeding tube 11 is 1.3 cm, and the diameter of the water injection tube 12 is 0.3 cm.

[0020] Furthermore, the internal fixation water-injection balloon 5 is made of medical silicone rubber material.

[0021] Furthermore, the limiting member 621 is ring-shaped.

[0022] Furthermore, the stoma leak-proof strip 2 is made of polyester foam.

[0023] Specifically, the stoma leak-proof strip 2 is made of polyester foam and can be bent and shaped arbitrarily according to the actual size of the stoma and then glued on.

[0024] Furthermore, a buckle 41 for fixing the gastrostomy tube body 1 is provided on the external fixing film 4 .

[0025] Specifically, a buckle 41 for fixing the gastrostomy tube body 1 is provided in the middle position of the external fixing film 4. The size of the buckle 41 matches the gastrostomy tube body 1. While firmly adhering to the abdominal wall, it keeps the gastrostomy tube body unobstructed and avoids pressure.
