Description

Double-ball type fat-reducing ball device

Technical Field

The invention relates to the field of medical instruments, in particular to a double-ball type weight-losing ball device.

Background

The weight-losing ball is also called gastric hydrosphere, intragastric balloon and the like. Fat reducing ball surgery is a very effective medical fat reducing means: inflatable balloons placed in the stomach through a gastroscope to occupy the space in the stomach, induce satiety to help control appetite, are used for assisted weight loss in obese patients. The product is typically removed after standing for several months and requires a combination of dietary instruction and behavioral modification.

The traditional weight-reducing ball body is composed of a single ball body. FIG. 4 is a simplified gastric structure with the fundus at the upper portion of the stomach. As shown in FIG. 5, the procedure is to place an empty balloon into the stomach through a gastroscope; the empty balloon was filled with physiological saline containing methylene blue to slowly expand the balloon until the balloon was in close contact with the stomach wall. The weight-reducing ball separates the stomach into an upper part and a lower part. As shown in fig. 6: a small space is reserved at the bottom of the stomach, and after a patient eats a small amount of food after operation, the food can stimulate the nerve at the bottom of the stomach to generate satiety, so that the patient stops eating the food. The number of food emptions is reduced because of the close contact between the balloon and the stomach wall. This allows obese patients to achieve weight loss by reducing food intake and slowing the number of gastric emptying.

The traditional weight-reducing ball has the following main defects:

1. the traditional fat reducing ball operation needs to fill water into the ball body, and the whole ball body is filled with water and has higher density, so that the ball body and the stomach wall are in a close fit state; discomfort is easy to occur in the stomach, and the ball body can press the gastric mucosa, which can easily cause erosion and ulceration of the mucosa and even corrode the stomach wall.

2. Traditional bariatric surgery is prone to overfill the sphere, may rupture, enter the small intestine and cause intestinal obstruction and ileus, endangering the life safety of the patient.

Disclosure of Invention

The invention aims to: a double-ball type weight-reducing ball device can effectively reduce the whole weight of the weight-reducing ball and reduce the oppression on the stomach.

The invention is realized by the following technical scheme: a double-ball type weight-reducing ball device comprises

Compared with the prior art, the invention has the beneficial effects that:

1. the ball body filled with the substances is lighter and safer, and can eliminate the risk of erosion and ulceration of mucosa and even corrosion of the stomach wall in the operation of a weight-reducing player.

2. The situation that the traditional bariatric player is easy to overfill the ball is reduced or eliminated, when the liquid of the outer capsule body exceeds a threshold value, the outer capsule body stops expanding, the inner capsule body is properly compressed, and the situation that the outer capsule body is broken is reduced or avoided.

3. Even if the outer capsule body breaks, the broken outer capsule body can not enter the small intestine due to the existence of the expanded inner capsule body, so that the hidden danger of intestinal obstruction is avoided.

Detailed Description

The invention is described in detail below with reference to the following description of the drawings:

as shown in fig. 1-3: double-ball type weight-reducing ball device, its characterized in that: it comprises

According to the different structures of the first channel and the second channel, the invention derives the following two embodiments:

example 1

As shown in fig. 1 and 2: the first channel is a first one-way valve 11, the feeding end of the first one-way valve 11 is arranged on the side wall of the outer bag body 1, and the discharging end of the first one-way valve 11 is arranged in the inner cavity of the outer bag body 1.

The second channel is a second one-way valve 21, the feeding end of the second one-way valve 21 is arranged on the side wall of the outer bag body 1, and the discharging end of the second one-way valve 21 penetrates through the side wall of the inner bag body 2 and extends into the inner cavity of the inner bag body 2.

In use, the first check valve 11 and the second check valve 21 are respectively connected with corresponding fluid passages, and the expansion of the outer bag body 1 and the inner bag body 2 is realized by injecting fluid.

Example 2

As shown in fig. 3: the outer capsule is provided with a one-way valve mechanism 3 with two passages, a passage A31 is communicated with the outside and the inner cavity of the outer capsule 1 to form a first passage, and a passage B32 is communicated with the outside and the inner cavity of the outer capsule 1 to form a second passage.

Basically the same principle as that of embodiment 1, except that there is only one check valve mechanism, but there are two passages in the check valve mechanism 3; when the inflatable bag is used, the two passages are respectively connected with the corresponding fluid channels, and the inflation of the outer bag body 1 and the inner bag body 2 is realized by injecting fluid.

The outer balloon 1 is spherical in shape. The shape of the ball is the same as that of the prior weight-losing ball.

The working mode and principle are as follows:

step 1: the outer bag body 1 and the inner bag body 2 are contracted into a beam shape; step 2: the present invention is placed in the stomach using a medical device such as a gastroscope; and step 3: injecting a certain volume of clean gas into the inner bag body 2 through the second channel to expand the inner bag body to a specified size; and 4, step 4: a volume of physiological saline solution containing methylene blue was injected into the outer capsule 1 through the first channel.

In practical use, a plurality of spheres can be placed according to the size of the stomach of an obese patient, and the spheres do not need to be in close contact with the stomach wall.

The principle of the invention is as follows:

different from the traditional single sphere structure, the double-layer capsule structure adopts an inner layer and an outer layer, and the inner air layer is wrapped by an outer water layer. The air layer and the water layer have certain volume proportion, and the double-ball system ball body has the advantages of reduced mass and lighter weight compared with the traditional ball body under the condition of the same volume. The ball is implanted in the stomach and always above the mixture of food and digestive juice. After the obese patient eats a small amount of food, the double-layer sphere floating above the food can stimulate the fundus nerves of the stomach, thereby generating satiety. As shown in fig. 6. Thereby reducing food intake. Due to the principle, the ball body is only required to be filled with a certain amount of normal saline in the operation, and the ball body is not required to be filled to be tightly contacted with the stomach wall. This eliminates the risk of overfilling and rupture of the conventional gastric balloon. Since the present invention does not make intimate contact with the stomach wall, this eliminates the risk of erosion, ulceration of the mucosa and even erosion of the stomach wall due to compression of the stomach wall. Because the weight of the weight-reducing ball is reduced, the discomfort of the obese patient can be greatly reduced.

While the invention has been illustrated and described with respect to specific embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the invention. It is understood, therefore, that the invention is not to be in any way limited except by the appended claims and their equivalents.
