Description

Technical Field

[0001] The invention belongs to the field of diet and weight loss devices, and in particular relates to an anti-blocking self-sealing mother-and-child ball diet and weight loss device. Background Art

[0002] After chewing, food passes through the esophagus and enters the stomach. The stomach is the organ that holds food during eating. The stomach's capacity is determined by its internal volume, directly influencing a person's appetite and food intake. A large stomach capacity coupled with a high food intake results in a state of "intake exceeding expenditure," a condition that underlies and provides the material basis for obesity. As living standards improve, lifestyles, eating habits, and dietary structure change, particularly among obese individuals, who have a voracious appetite and large food intake, the number of obese individuals is increasing, leading to a rising incidence of obesity-related metabolic diseases and a serious impact on human health.

[0003] In daily life, people typically lose weight through health management and medical intervention. A balanced diet, especially moderate dieting and exercise, are key factors in health management. While moderate dieting is one of the most important weight loss measures, resisting strong food cravings requires considerable willpower and endurance, making it difficult for most people to maintain. Currently available intragastric balloon surgery offers many advantages, such as significantly reducing food cravings, spontaneously reducing food intake, and effectively controlling weight and blood sugar. However, existing intragastric balloons present the following problems and risks: 1. After insertion, intragastric balloons have a certain rate of spontaneous rupture, which can easily pass through the pylorus and enter the intestine, causing life-threatening intestinal obstruction; 2. The anti-overflow seal for the intragastric balloon is implemented using a metal mechanical check valve, which is complex and less user-friendly; 3. Once filled with water, the intragastric balloon weighs a significant amount, and prolonged fixed position compressing the gastric mucosa can cause side effects such as abdominal distension, acid reflux, vomiting, gastric ulcers, and bleeding. Therefore, innovation and improvement of existing products are needed. Summary of the Invention

[0004] The purpose of the present invention is to address the problems and risks of the above-mentioned products and provide an anti-blocking and self-sealing mother-and-child ball diet and weight loss device to solve the problems that existing diet devices (such as intragastric balloons) are prone to intestinal obstruction once damaged in the body, and the automatic sealing of the balloon relies on a mechanical check valve, which is prone to cause stomach discomfort.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an anti-blocking self-sealing mother-and-child ball dieting device, comprising a catheter and a mother-and-child ball, the catheter being divided into a proximal end and a distal end, the proximal end being a straight tube, provided with a connecting port and a water vapor inlet, the distal end being a spiral tube, having a memory shaping function, a common channel for water, gas and guide wire being provided inside the catheter, and the channel being closed at the terminal end of the spiral tube; the mother-and-child ball comprises a daughter ball and a mother ball, the daughter ball being wrapped around the outer periphery of the proximal end of the catheter, the two ends of the daughter ball being fixed to the catheter by silk thread and glue sealing, a pinhole being reserved in the middle of the daughter ball body as the water vapor inlet of the daughter ball, the mother ball being wrapped around the outer periphery of the daughter ball, the two ends of the mother ball being fixed to the catheter by silk thread and glue sealing, and the catheter connecting port being exposed.

[0006] Furthermore, the diameter of the spiral structure at the distal end of the catheter is greater than 3 cm.

[0007] Furthermore, the mother ball is elliptical.

[0008] Furthermore, the daughter ball and the mother ball form a double-ball conjoined staggered channel, which is a single-circulation channel for water and gas from the proximal connection port of the catheter to the water vapor inlet of the catheter to the water vapor inlet of the daughter ball to the mother ball.

[0009] Furthermore, the catheter is made of polyurethane, and the daughter ball and mother ball are made of silicone rubber.

[0010] Furthermore, the catheter is 10-15 cm long and 0.5-0.6 cm in diameter; the daughter ball is round, with a diameter of 3-4 cm and a thickness of 0.3-0.4 mm after filling; the mother ball has a diameter of 4-5 cm, a length of 10-12 cm and a thickness of 0.3-0.4 cm after filling.

[0011] The anti-blocking self-sealing mother-and-child ball dieting and weight loss device method comprises the following steps:

[0012] Insert the guide wire into the catheter channel, straighten the distal spiral structure of the catheter, and place the device into the gastric cavity through the mouth;

[0013] Withdraw the guidewire to restore the distal end of the catheter to a spiral shape;

[0014] 500-700ml of water and air are injected into the catheter through the connecting tube. The water and air enter the daughter balls through the water vapor inlet of the catheter, and then overflow to the mother ball through the water vapor inlet of the daughter balls. The mother ball is filled and generates tension, which presses back on the daughter balls, causing the daughter balls to collapse and close the channel.

[0015] After the cue ball remains filled in the stomach cavity, remove the connecting tube;

[0016] When the device needs to be removed, the mother ball is punctured with the assistance of a gastroscope, and the device is removed through the esophagus after the water and air are discharged.

[0017] The principle and beneficial effects of the present invention: The distal end of the catheter adopts a spiral tubular structure, which has a memory shaping function, and its spiral diameter is greater than 3 cm. When the device is placed in the gastric cavity, the spiral tube automatically restores its shape after the guide wire is withdrawn, and the diameter of the human pylorus is usually less than 3 cm. The spiral structure cannot pass through the pylorus due to geometric size limitations. Even if the device is damaged in the body, the fixed shape of the spiral tube can still prevent fragments from entering the intestine. It completely avoids the risk of the existing intragastric balloon blocking the intestine through the pylorus after damage, without relying on additional anti-blocking structures, and only achieves safety protection through physical shape design, which buys time for the removal of the device after damage, significantly reducing the risk of life-threatening intestinal obstruction.

[0018] When water and air are injected into the mother ball to fill it, the tension generated by the mother ball pushes the daughter balls inward, causing them to collapse. The collapsed daughter balls then pressurize the conduit channel, creating an "in-only, no-exit" seal similar to a mechanical check valve. This process requires no metal mechanical components, relying entirely on the elastic interaction of the two balls. Automatic sealing achieved through purely physical structural interaction avoids the potential failure risks of mechanical components (such as jamming and corrosion), while simplifying the process, reducing costs, and achieving higher sealing reliability, more in line with the human needs of human use.

[0019] The water-air mixture significantly reduces weight compared to a full water filling method, and the center of gravity of the gas-liquid mixture shifts with body position, reducing fixed pressure points. This device significantly improves gastric compatibility, reducing side effects such as abdominal distension, acid reflux, and gastric ulcers caused by long-term placement, and improving user comfort.

[0020] In summary, the present invention solves the problem that existing dieting devices (such as intragastric balloons) are prone to intestinal obstruction once damaged in the body, and the automatic closure of the balloon relies on a mechanical check valve, which is prone to cause stomach discomfort.

DETAILED DESCRIPTION

[0028] The following is further described in detail through specific implementation methods:

[0029] Anti-blocking self-sealing mother-and-child ball dieting device (such as Figure 1-6 The device (shown) consists of a conduit and a mother ball, made of polyurethane and silicone rubber respectively, which are soft, smooth and corrosion-resistant.

[0030] The catheter is relatively divided into two parts, a proximal end 1 and a distal end 2 (each occupying 1 / 2 of the length). The proximal end 1 is a straight tube, and the distal end 2 is a spiral tube, with the spiral tube terminal closed. The distal end 2 has a spiral shape, and its spiral shape has a diameter greater than 3 cm. This special geometric shape ensures that the device will not pass through the pylorus of the human stomach under any circumstances, avoiding the risk of intestinal obstruction caused by intestinal obstruction, and buying time for endoscopic removal of a damaged device to ensure personal safety.

[0031] The catheter's interior is equipped with a common channel 5 for both water and a guidewire 10. Because this channel 5 is completely sealed at the end of the spiral tube, the guidewire 10 provides a fulcrum for straightening the spiral tube. This also ensures that water and vapor do not leak during operation within the stomach cavity. The distal end 2 of the catheter's spiral tube has a fixed memory function. During transoral placement of the device, the guidewire 10 is easily straightened upon entry, allowing direct placement into the stomach. Upon withdrawal, the guidewire 10 automatically resets to its original spiral shape. The daughter ball 6 and mother ball 8 seal the proximal end 1 of the catheter. When inflated, the daughter ball 6 assumes a circular shape, while the mother ball 8 assumes an "elliptical" shape. The specific production method is to first put the sub-ball 6 on the proximal end 1 of the catheter (the water vapor inlet 4 is wrapped), and the two ends of the sub-ball 6 are sealed and fixed to the catheter with silk thread and glue (the catheter connection port 3 is exposed), and a pinhole is reserved in the middle of the sub-ball 6 as the catheter water vapor inlet 7 (the outlet is connected to the mother ball 8), and then the mother ball 8 completely wraps the sub-ball 6, and the two ends of the mother ball 8 are sealed and fixed to the proximal catheter 1 in the same way (the catheter connection port 3 is exposed).

[0032] The channel formed by the proximal catheter 1 being wrapped in double layers inside and outside the daughter ball 6 and the mother ball 8 has smooth entry of water and air due to the structural principle of the "double-ball connected staggered channel". The two balls interact with each other, and their force and direction will change with the change of force, and the channel can be closed spontaneously; a single circulation of water and air "only in but not out" is formed between "catheter proximal connection port 3 → catheter water and gas inlet 4 → daughter ball water and gas inlet 7 → mother ball 8", which can automatically close the channel.

[0033] The specific description of the working mechanism of the "double-ball connected staggered channel" and the "double-ball interaction" is: when water and air are injected through the connecting tube 10, water and air enter the sub-ball 6 through the water and air inlet 4 at the proximal end of the catheter, and overflow into the mother ball 8 through the water and air inlet 7 of the sub-ball. When the water and air reach a certain amount, the mother ball 8 expands, generating surface tension and gradually increasing to a certain extent, resulting in overall back pressure of the mother ball 8. This all-round back pressure causes the sub-ball 6 to collapse, and the collapsed sub-ball 6 then back-pressures to self-block the entire channel (similar to the principle and effect of a mechanical check valve). After the connecting tube 10 is removed, the mother ball 8 will not leak in the gastric cavity; the mother ball 8 automatically seals and maintains a stable filling state in the gastric cavity, thereby achieving the effect of dieting and weight loss; the device of the present invention can be easily removed with the assistance of a gastroscope under any circumstances.

[0034] The method of using the present invention is to first check that the device is not damaged, and insert a metal guide wire 1010 and a connecting tube 109 (an existing mature product) into the channel through the proximal connecting port 3 of the catheter of the device, wherein the front end of the connecting tube 109 is inserted into the connecting port 3 (about 1 cm deep) and relatively squeezed and fixed; then the guide wire 1010 penetrates into the distal end 2 of the catheter to straighten the spiral tube; after the outer surface of the device is evenly coated with lubricant, it is directly introduced into the gastric cavity through the mouth, pharynx, and esophagus. After confirming that it has entered the gastric cavity, the guide wire 10 is withdrawn, and the distal end 2 of the catheter now returns to its spiral shape. Once the device is spontaneously damaged in the body, the spiral tubular structure cannot enter the intestine through the pylorus, thereby avoiding the risk of intestinal obstruction and life-threatening risks;

[0035] Then, use a syringe to inject the expected amount of water and air into the catheter through the connecting tube 109. Due to the principle of the "double-ball connected staggered channel", the two balls interact with each other, and water vapor enters the daughter ball 6 through the water vapor inlet 4 of the catheter, and then overflows to the mother ball 8 through the water vapor inlet 7 of the daughter ball. The water and air cause the mother ball 8 to gradually bulge and slowly generate tension. After reaching a certain level, the mother ball 8 elastically back-presses in all directions, squeezing the daughter ball 6 to collapse and automatically close the entire channel (at this time, the syringe can be withdrawn to cause the daughter ball 6 to be under negative pressure and automatically maintain it). The expected amount of water and air injected is 500-700ml (water: air ratio of about 1:1). After the injection is completed, the connecting tube 1010 is pulled outward by elastic external force. At this time, the water vapor is sealed and retained in the mother ball 8, keeping the mother ball 8 filled for a long time, thereby producing a diet and weight loss effect.

[0036] After the device has achieved its intended purpose within 3-6 months, the mother ball 8 is punctured with the aid of a gastroscope. Once the water and air have escaped, the device is removed through the esophagus. The mother-and-child ball structure features two key features: 1. Easy filling and operation, effective for weight loss; 2. Automatic sealing and leak prevention, making it safer, simpler, and more user-friendly than a mechanical check valve.

[0037] The present invention has a unique spiral shape at the distal end of the catheter. During use, the distal spiral 2 of the catheter can be straightened and expanded by a guide wire 1010. After placement in the gastric cavity, the guide wire 1010 is withdrawn from the catheter 9, and the distal end 2 of the catheter is restored to its spiral shape, which can avoid intestinal obstruction. The interiors of the mother ball 8 and the daughter ball 6 are filled with water and air in appropriate proportions. While the intragastric balloon is more completely filled with water, the water and air are mixed in the mother ball 8. The flow of its center of gravity will change with the person's body position (but the mother ball 8 will not be misplaced or reversed in the gastric cavity), avoiding the long-term fixed center of gravity of the device pressing on the local area of the stomach, which can improve comfort.

[0038] In practice, the catheter has a total length of 10-15 cm and a diameter of 0.5-0.6 cm. It is divided into two parts, a proximal end 1 and a distal end 2, each occupying half the length. A common channel 5 (aperture 0.1-0.2 cm) is provided inside the catheter for both water vapor and a guidewire 10. A bell-shaped water vapor inlet 4 is reserved at the proximal end 1. The distal end 2 is machined into a 360-degree spiral arc shape (arc diameter 3-4 cm) with memory and shaping capabilities. During insertion, it can be straightened by the guidewire 1010 and automatically returns to its spiral shape upon removal of the guidewire 10. The distal end of the catheter is closed. The outer surface of the proximal end 1 is ligated with a daughter ball 6 and a mother ball 8, respectively. The daughter ball 6 encases the water vapor inlet 4.

[0039] The sub-ball 6 is round, 0.3-0.4mm thick, and 3-4cm in diameter, wrapping the proximal end 1 of the catheter (the water vapor inlet 4 is wrapped). A pinhole is reserved in the sub-ball 6 opposite to the water vapor inlet 4 as the catheter water vapor inlet 7. The two ends of the sub-ball 6 are tied with silk thread and sealed with special glue to the proximal end 1 of the catheter (the catheter connection port 3 is exposed).

[0040] The mother ball 8 is oval in shape, 0.3-0.4 cm thick, 4-5 cm in diameter, and 10-12 cm long, roughly twice the size of the daughter ball. The mother ball 8 is wrapped around the daughter ball 6 and similarly secured at both ends (with the catheter connection 3 exposed), forming a "double-ball conjoined staggered channel" structure. The connecting tube 10, approximately 50-55 cm long, is secured to the proximal catheter connection 3 with tension. A guidewire 10 hole is provided inside the catheter to facilitate its entry and exit.

[0041] It should be noted in advance that, in the present invention, unless otherwise expressly specified or limited, terms such as "install," "insert," "connect," and "fix" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0042] The above is only an embodiment of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
