Description

Technical Field

[0001] The present application relates to the technical field of weight loss medical devices, and in particular to a weight control device. Background Art

[0002] At present, there are nearly 600 million people in China who are obese or overweight. Obesity or overweight will increase the burden on the body and cause diseases such as high blood pressure, diabetes and coronary heart disease. The main reason for this is excessive consumption of high-sugar, high-salt and high-fat foods, or the fast-paced life and work pressure that increase the secretion of some stress hormones such as cortisol and adrenaline. The strong secretion of stress hormones will make people rely on eating to reduce the release of these stresses, that is, eating too much but exercising less, and the remaining nutrients cannot be metabolized in time and accumulate in the body, forming obesity.

[0003] At present, the weight loss products on the market mainly include drugs for weight loss. For example, drugs form covalent bonds with the active serine sites of gastric lipase and pancreatic lipase in the stomach and small intestine to inactivate the enzymes and exert therapeutic effects. Inactivated enzymes cannot hydrolyze fat in food into absorbable free fatty acids and monoacylglycerols, thereby reducing calorie intake and controlling body weight. In addition, there are also ways to lose weight through implantable medical devices, such as gastric bypass stents, which use gastroscopy to insert a sleeve in the duodenum and upper jejunum to isolate chyme and reduce absorption. It is removed after 3 to 6 months of insertion, and the normal physiological system of the human body is used to regulate hormones in the body to achieve weight loss.

[0004] However, these weight loss methods involve drug dependence or surgical risks and are more suitable for treating obese people. For normal people, there is still a need for relatively safe and simple new methods to lose weight. Utility Model Content

[0032] This application proposes a weight control device based on the principle of forming a false sense of fullness by stimulating the stomach in the body. The specific principle is: vibrating in the stomach with a preset frequency range to stimulate the inner wall of the stomach, so that the human body obtains a virtual sense of stomach expansion through the stomach mechanical receptors, and then causes the stomach vagus nerve to release a neural signal of fullness to the solitary tract nucleus of the brain, so that the brain can feel fullness when the amount of food intake is reduced, which promotes the user to reduce food intake and achieve the purpose of weight control.

[0033] Figures 1 to 4FIG. 2 shows a schematic embodiment of the weight control device of the present application. Figures 1 to 4 As shown, the present application discloses a weight control device, which includes: a vibrating capsule 1 and a chest wearable device 2. The vibrating capsule 1 includes: a vibrating component 11 for vibrating and stimulating the stomach of the swallower, a wireless communication component 12 for wireless communication with an external device, and a magnet component 13. The chest wearable device 2 includes: a power supply component 21, a magnetic field component 22 and a control component 23, the power supply component 21 connects the magnetic field component 22 and the control component 23, and the control component 23 is used to control the magnetic field component 22 to form a hysteresis magnetic field, and the hysteresis magnetic field is used to prolong the residence time of the vibrating capsule 1 in the stomach of the swallower.

[0034] Through the above-mentioned structural design, the embodiment of the present application uses the method of matching the vibrating capsule 1 with the chest-worn device 2 to make the swallower produce a false sense of fullness by virtue of the stomach vibration of the vibrating capsule 1, thereby reducing food intake and controlling weight. The chest-worn device 2 is used to generate a hysteresis magnetic field covering the vibrating capsule 1 to slow down the speed of the vibrating capsule 1 moving along the digestive tract, thereby prolonging the residence time of the vibrating capsule 1 in the stomach and ensuring that the vibration stimulation achieves the weight loss requirements.

[0035] In some embodiments of the present application, the chest wearable device 2 is, for example, a chest strap or a chest vest. The chest strap and the chest vest can be easily worn on the body without hindering human movement, and there is no need to constrain the user to stay still and wait for the vibration to end, so it is more flexible and convenient to use. At the same time, the chest wearable device 2 can arrange the magnetic field component 22 near the stomach of the human body, so as to more conveniently form a hysteresis magnetic field to cooperate with the vibration capsule 1, prolong the time that the vibration capsule 1 stays in the stomach, ensure sufficient vibration stimulation, and achieve a reliable weight management effect.

[0036] refer to Figure 2 As shown in the exploded view, the vibration capsule 1 includes an acid- and alkali-resistant shell, a vibration component 11 such as a polarization motor is disposed in the shell, a built-in circuit board 16 is disposed on one side of the vibration component 11, and a circuit structure such as a magnet component 13 is arranged on the circuit board 16. The magnet component 13 is, for example, an electromagnet, and the magnetism of the magnet component 13 can be controlled by the power interruption of the vibration capsule 1 itself.

[0037] In some embodiments of the present application, Figure 1As shown, the magnetic field component 22 of the chest wearable device 2 includes a plurality of electromagnets respectively arranged at the chest and back positions of the swallower corresponding to the chest wearable device 2, and the magnetic field component 22 is used to form a circular hysteresis magnetic field through these multiple electromagnets. Compared with the magnetic field formed by a single electromagnet, the circular magnetic field formed by the superposition of multiple electromagnets has an adjustable magnetic field direction and intensity at any point in the magnetic field, so as to better meet the hysteresis magnetic force requirements of the vibrating capsule 1 in different positions and postures, with a larger adjustable range and stronger adaptability. In the embodiment of the present application, for cost and chest strap size and weight considerations, two sheet-shaped electromagnets are respectively arranged in front and behind the chest wearable device 2 in this embodiment. It can be understood that in some other embodiments of the present application, a larger number of electromagnets can also be provided, which are not listed here one by one.

[0038] In some embodiments of the present application, Figure 1 As shown, the vibration capsule 1 also includes a first IMU component (the first IMU component is placed on the built-in circuit board 16 of the vibration capsule 1), and the first IMU component is used to detect the posture of the vibration capsule 1 in the body of the swallower, so as to facilitate the control of vibration parameters and hysteresis magnetic field parameters according to the posture of the vibration capsule 1. The wireless communication component 12 is electrically connected to the first IMU component, and is used to send the posture information of the vibration capsule 1 in the body of the swallower to an external device (such as a portable mobile terminal such as a mobile phone or a tablet computer). IMU refers to an inertial sensor unit (Inertia lMeasurementUnit), which includes an accelerometer, a gyroscope and a magnetometer, and can realize 9-axis motion measurement to determine the posture of the object to be measured. By detecting the posture of the vibration capsule 1, the present application can adopt different vibration modes and magnetic field modes for different postures, thereby realizing posture adjustment and correction through the swing of the vibration capsule 1. This method is particularly suitable for a vibration capsule 1 with an endoscopy function, and the vibration capsule 1 can be driven by posture adjustment to capture internal images of a specific position, so as to better serve health detection and enrich product functions.

[0039] In some embodiments of the present application, Figure 1 As shown, the chest wearable device 2 also includes: a second IMU component 24, which is used to detect the sitting or lying posture of the swallower. The control component 23 is connected to the second IMU component 24 to obtain the sitting or lying posture information of the swallower, and adaptively adjusts the hysteresis magnetic field parameters of the magnetic field component 22 according to the sitting or lying posture of the swallower.

[0040] For example, refer to Figure 3 and Figure 4 As shown, in Figure 3 When the human body is in a standing position, the thrust F of the gastric peristalsis 胃 The hysteresis magnetic field F is vertically downward in the same direction as the gravity G. At this time, the control component 23 adjusts the hysteresis magnetic field parameters according to the standing posture of the human body, so that the hysteresis magnetic force F磁 Vertically upward in the opposite direction, thereby suppressing the downward trend of the vibrating capsule 1 and prolonging the residence time of the vibrating capsule 1 in the stomach; Figure 4 When the human body is in a side-lying position, the thrust F of the gastric peristalsis 胃 and gravity G in different directions downwards. At this time, the control component 23 adjusts the hysteresis magnetic field parameters according to the side-lying posture of the human body so that the hysteresis magnetic force F 磁 In the opposite direction, it moves diagonally upward, thereby suppressing the downward trend of the vibrating capsule 1 and prolonging the residence time of the vibrating capsule 1 in the stomach. In the embodiment of the present application, the second IMU component 24 for detecting the human body posture is set on the chest wearable device 2 instead of the vibrating capsule 1. On the one hand, it simplifies the structural design and makes full use of the space of the external wearable device. On the other hand, it also ensures the battery life of the vibrating capsule 1 and avoids the problem of insufficient power of the vibrating capsule 1 and insufficient vibration for the preset time.

[0041] In some embodiments of the present application, the chest wearable device 2 further includes: an interrupt circuit component (not shown, placed on the control component 23), the interrupt circuit component electrically connects the control component 23, the magnetic field component 22 and the second IMU component 24, and the control component 23 is also used to control the magnetic field component 22 to be turned off when the second IMU component 24 is working through the interrupt circuit component, thereby avoiding the hysteresis magnetic field from causing magnetic interference to the second IMU component 24. It can be understood that in the embodiments of the present application, the hysteresis magnetic field can be set to an intermittently turned on annular magnetic field, which is driven by the interrupt circuit component by setting the interrupt time. The first IMU component and the second IMU component 24 run in sequence during the period when the hysteresis magnetic field is turned off, and the posture information of the vibration capsule 1 and the posture information of the human body are respectively obtained in an interval acquisition manner, thereby providing data support for controlling the vibration capsule 1.

[0042] In some embodiments of the present application, the vibrating capsule 1 further includes a pH detection component 14 for detecting the pH value of gastric digestive fluid. Figure 2 As shown in the exploded view, the vibrating capsule 1 includes an end cap 15, on which a liquid inlet 151 is provided, and the pH detection component 14 is provided at the position of the liquid inlet 151. When the vibrating capsule 1 is swallowed, it enters the human stomach after about 60 seconds. At this time, the pH detection component 14 detects that the pH value of the digestive fluid is a preset value (the pH value of the stomach digestive fluid is about 4), that is, it is judged that the vibrating capsule 1 has entered the stomach, thereby turning on the vibration mode, and transmitting the working information to the external device through the wireless communication component 12.

[0043] In some embodiments of the present application, the vibrating capsule 1 also includes a lighting and shooting component, which is used to capture vital signs information in the digestive tract of the swallower. The wireless communication component 12 is electrically connected to the lighting and shooting component to send the vital signs information in the digestive tract of the swallower to an external device, so that the vibrating capsule 1 of the present application can also realize an endoscopic function and further serve human health.

[0044] In some embodiments of the present application, the outer shell of the vibrating capsule 1 is a threaded structure, and the threaded outer shell can facilitate the vibrating capsule 1 to divert digestive juice in the digestive tract, and facilitate digestive juice and food gruel to flow through the side of the vibrating capsule 1, which can also reduce the probability of the vibrating capsule 1 being attached to the inner wall of the digestive tract and stagnating. Preferably, the thread tooth profile of the vibrating capsule 1 is an arc shape with a smooth tooth top to avoid scratching the stomach wall.

[0045] In some embodiments of the present application, the weight control device also includes a mobile smart terminal, which is wirelessly connected to the vibration capsule 1, can view the working parameters of the vibration capsule 1 in real time, and allows the user to control the vibration capsule 1 through the APP on the mobile smart terminal to customize parameters such as vibration intensity and vibration time to achieve a personalized customization effect.

[0046] Combination Figures 1 to 4 The embodiment shown illustrates the working principle of the weight control device of the present application:

[0047] First, the user swallows the vibrating capsule 1. After the vibrating capsule 1 enters the stomach, the pH value given by the pH detection component 14 indicates the start (the stomach is an acidic environment with a pH value of less than 4, and the intestine is a weakly alkaline environment with a pH value of more than 7). The user wears a chest strap (i.e., a chest wear device 2) provided with a magnetic field component 22. The chest strap turns on the magnetic field component 22 to form a hysteresis magnetic field covering the vibrating capsule 1 (the typical working intensity value is 0.05-0.1 Tesla). The hysteresis magnetic field can slow down the movement speed of the vibrating capsule 1 in the stomach, thereby providing a sufficient vibration time of more than 30 minutes in the stomach, allowing the vibrating capsule 1 to form a false sense of fullness by stimulating the stomach wall, reducing the user's desire to eat to control weight. At the same time, the user can also use a mobile smart terminal (such as a mobile phone or tablet computer, etc.) to communicate with the vibrating capsule 1 through a wireless connection, control the vibration mode of the vibrating capsule 1, and record the use of the vibrating capsule 1 to make a health log, so as to carry out scientific and effective weight management.
