Abstract
The invention discloses a non-return instrument for a stomach capacity reduction balloon. The non-return instrument comprises a non-return valve, an oblate tube and a mini-diameter tube; the injection port of the valve is communicated with the oblate tube via a gap between the injection port and the oblate tube, the tail end of the oblate tube is provided with the mini-diameter tube, a crack is formed in the side wall of the mini-diameter tube, and the oblate tube can be communicated with the outside world via the crack. Under certain pressure, liquid or gas injected from the injection port enters the mini-diameter tube through the oblate tube to flow out by opening the crack of the mini-diameter tube; when the balloon is filled to certain extent, the oblate tube is squeezed to have the tube wall tightly adhered, the liquid or the gas in the balloon cannot escape, and the non-return function is achieved.
Description
Technical field
The present invention relates to field of medical equipment technology, in particular for the backstop of stomach volume reduction sacculus.
Background technology
Implantable gastric volume reduction sacculus is as a kind of method of naturopathy obesity, its action principle is that the sacculus with certain volume occupies gastric space, decrease the capacity of stomach, make patient take food on a small quantity and i.e. produce feeling of repletion, thus reach to control and improve the purpose of body weight by controlling food-intake.But in use, the check valve of sacculus is not the most airtight tight, and in sacculus, liquid can produce leakage, causes balloon volume to reduce, affects therapeutic effect.
Summary of the invention
For the leakage problem of check valve during overcoming stomach volume reduction sacculus to use, the present invention provides a kind of stomach volume reduction sacculus backstop.
The technical solution used in the present invention is: a kind of stomach volume reduction sacculus backstop, including check valve (1), flat pipe (4) and mini diameter tube (5), described check valve (1) is connected with flat pipe (4), the injection port (2) in check valve (1) and have gap (3) to connect between flat pipe (4)；The end of described flat pipe (4) connects mini diameter tube (5), and the sidewall of mini diameter tube (5) has a gap (6), and flat pipe (4) can communicate with the external world through thus gap.
Described check valve (1) is rubber or other elastomeric materials are made.
Described flat pipe (4) and mini diameter tube (5) are rubber or other elastomeric materials are made, and soft and flexible, the inwall of flat pipe is close together at ordinary times.
Described stomach volume reduction sacculus backstop, during Clinical practice, under a certain pressure, liquid or gas can enter flat pipe (4) from injection port (2) by gap (3), entered in sacculus by the gap (6) of mini diameter tube (5) tube wall.Sacculus constantly fills along with the injection of liquid, and flat pipe (4) is squeezed, and tube wall tightly sticks together, and the liquid in sacculus cannot escape.
The invention have the advantage that the sacculus installing this backstop is injected into liquid and expands, owing to the high resiliency of sacculus produces bigger pressure to the liquid of its inside, this pressure also simultaneously acts on gap (3) and the flat pipe (4) of injection port end, add gap and the sealing force of flat pipe, improve the reliability of sealing.Simultaneously, this backstop by being converted into the sealing force of closure ball CF body adverse current by stomach volume reduction sacculus by the extruding force that stomach extrudes, realize the non-return effect of liquid in sacculus by extruding airtight flat pipe (4) and mini diameter tube sidewall gap (6) two-layer measure, improve the reliability of sealing.

7. backstop, 8. stomach volume reduction sacculus.
Detailed description of the invention
In order to be more fully understood that the present invention, it is further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of stomach volume reduction sacculus backstop, including check valve (1), flat pipe (4) and mini diameter tube (5).Check valve (1) is connected with flat pipe (4), the injection port (2) in valve (1) and have gap (3) to connect between flat pipe (4)；The end of flat pipe (4) connects mini diameter tube (5), and the tube wall of mini diameter tube has a gap (6), and flat pipe (4) can be communicated with the external world by gap (6).Described check valve (1), flat pipe (4) and mini diameter tube (5) are rubber or other elastomeric materials.
Fig. 2 illustrates the assembly case of stomach volume reduction sacculus and backstop, and in this example, stomach volume reduction sacculus uses together with adhesives with backstop, seals, firmly.Stomach volume reduction sacculus before using needs to evacuate, be folded into elongated strip, in order to send into gastric.
During use, stomach volume reduction sacculus is inserted gastric by special induction system, and injects liquid by this induction system in sacculus via backstop；Under a certain pressure, liquid enters flat pipe (4) from injection port (2) by gap (3), is entered in sacculus by the gap (6) on mini diameter tube (5) tube wall of flat pipe end.Sacculus constantly fills along with the injection of liquid, and its internal pressure the most constantly increases, and flat pipe (4) is squeezed, and tube wall tightly sticks together, and the liquid in sacculus cannot be escaped by flat pipe (4)；The gap (3) that injection port (2) is held simultaneously also tightly closes because of pressure, blocks return flow line, it is achieved Double reversing-proof function.Meanwhile, stomach volume reduction sacculus inserts gastric, and sacculus can be extruded by coat of the stomach, and this extruding force also can improve the non-return effect of backstop.
Claims (3)
1. a stomach volume reduction sacculus backstop, it is characterised in that include check valve (1), flat pipe (4) and mini diameter tube (5)；
Described check valve (1) is connected with flat pipe (4), the injection port (2) in check valve (1) and flat pipe (4) it
Between have gap (3) to connect；The end of described flat pipe (4) connects mini diameter tube (5), and the sidewall of mini diameter tube (5) has one
Bar gap (6), flat pipe (4) can communicate with the external world through thus gap.
2. a kind of stomach volume reduction sacculus backstop as claimed in claim 1, it is characterised in that described check valve (1) is rubber
Glue or other elastomeric materials are made.
3. a kind of stomach volume reduction sacculus backstop as claimed in claim 1, it is characterised in that described flat pipe (4) and thin circle
Pipe (5) is rubber or other elastomeric materials are made.
