The specific embodiment
Has an inextensible back 4 in that the stomach band shown in Fig. 1 and 2 is the same with the stomach band that uses at present.Two chambers 1,2 are positioned at the side in the face of coat of the stomach 13 at back 4, and these two chambers interconnect, and can realize liquid moving between chamber 1,2 thus.In the face of chamber 1,2 circumferential of stomach band 13 ground extends around stomach or esophagus, as at the common stomach band that only has a chamber.In an illustrated embodiment, auxiliary chamber 3 with air chamber function is positioned at the outside that deviates from coat of the stomach 13 at back 4.This auxiliary chamber 3 is connected with two chambers 1,2.Valve 5 between chamber 1 and auxiliary chamber 3 allows liquid from chamber 1 to auxiliary chamber 3.Allow liquid to transfer to from auxiliary chamber 3 chamber 2 of constraint appetite at the chamber 2 of constraint appetite and another valve 6 between the auxiliary chamber 3.Pressure in two chambers 1,2 that make contiguous coat of the stomach 13 by appetite during through-flow solid food is brought up to a pressure p 2 from a static pressure p1 thus.Therefore liquid is pressed onto the auxiliary chamber 3 from chamber 1.Described valve 5 prevents from auxiliary chamber 3 to chamber 1 backflow.Since the air chamber function, the 3 storage elevated pressure p2 of auxiliary chamber.After food is by appetite, dropping to static pressure p1 near the fork of the fluid pressure in two chambers 1,2 of coat of the stomach.After this, the auxiliary chamber 3 that is under the rising pressure p 2 is emptied to liquid in the chamber 2 of constraint appetite.Therefore the pump machanism by pure machinery here moves to the chamber 2 of constraint appetite liquid at solid food during by appetite from chamber 1.Appetite hole (Stomaoeffnung) regulated narrower and smallly, as shown in Fig. 2 with the height of chamber 2.Described liquid moves during diet and carries out continuously.After the definite time after the meal, being back to chamber 1 by the chamber 2 from the constraint appetite, that stomach band is adjusted to is wideer.The best time for this fluid exchange must be determined by clinical research.Relate to a kind of stomach band in the embodiment according to Fig. 1 and 2, it has a liquid circulation that constitutes by chamber 1,2 and auxiliary chamber 3.Fluid exchange realizes by micropore in the embodiment shown, and they are arranged on the separates walls between adjacent chamber 1 and 2.Produce a successive slowly fluid balance thus.The control of pumping process can be carried out electronically or mechanically.
Therefore, move to another chamber from a chamber, realize regulating automatically the purpose of appetite wide variety by making liquid.Compare with the original state of equally distributed amount of liquid in two chambers, uneven distribution means constraint appetite in a chamber position and is made the appetite expansion with the height of another chamber.Effect for the stomach band wearer means an appetite constraint and relevant therewith diet processes difficulty.
Embodiment at a stomach band shown in Fig. 3 and 4 illustrates flexible program, for it is provided with two liquid circulations.At this, this stomach band is the same with the stomach band that uses at present to have an inextensible back 4.There are two chambers 1,24 the side in the face of coat of the stomach 13 at the back, their effect connections each other.The chamber 1 that relative stomach is arranged on head (kranial) has the function of a pick off and detect the motion of the harmonization of the stomach esophagus that causes during pickuping food.The chamber 2 that is positioned at chamber 1 next door of sensing is used to retrain appetite and is in a deposit chamber 9 and is connected.Liquid can be pumped into chamber 2 from this deposit chamber 9 also gets back to the deposit chamber 9 from this chamber is defeated again.For example electronic circuit 11 is used for being connected with effect between 2 at chamber 1, and the pressure that this wireline inspection is received by the chamber 1 of sensing is also correspondingly controlled an electric pump 12.This electric pump 12 is transported to liquid chamber 2 and realizes the constraint appetite thus from deposit chamber 9.Therefore this constraint of appetite/narrow down and after definite food is by chamber 1, carry out.Chamber 1 pressure inside the food of swallowing by the time raise, the stomach band that therefore can use a controllable common version is as the pick off that is used for swallowing activity.By liquid is moved on to the chamber 2 and retrains appetite from deposit chamber 9, be moved back in the deposit chamber 9 by liquid appetite is broadened.
Fig. 4 illustrates a modification according to adjustable stomach band of the present invention, wherein, chamber 1 and with the chamber 2 that is connected of deposit chamber 9 between connection by 14 realizations of a pressure suction type pump.In this case, in the chamber 1 of sensing during pickuping food elevated pressure be used for pump and fill chamber 2.Therefore, liquid in the chamber 1 of sensing handles pressure suction type pump 14 and the valve 7,8 by relative set impels flow of liquid to flow to the chamber 2 from deposit chamber 9, and therefore impel pump to fill chamber 2 and retrain appetite thus.Therefore by an auxiliary chamber 3 with air chamber function is set between valve 8 and another valve 10, can realizes the flow of liquid of a delay and realize the constraint of a delay of appetite.Realize that by a return flow line 17 liquid is back to the deposit chamber 9 from chamber 2, a choke valve 15 for example can be set in this return flow line, it plays an effect that triggers the appetite constraint lentamente.Therefore pump machanism is deactivated and is realized that liquid flows to from chamber 2 the deposit chamber 9 lentamente after diet finishes.There is not energy expenditure ground to realize liquid return according to chamber 2 and the barometric gradient between the deposit chamber 9 in the constraint appetite.Barometric gradient of essential existence between chamber 2 and deposit chamber 9 is because deposit chamber 9 is positioned at the outside of back 4 and does not therefore improve static pressure simultaneously along with being full of the chamber 2 that retrains appetite.
Be also that according to the embodiment scheme of Fig. 4 and difference two chambers 1,2 are provided with up and down overlappingly with respect to coat of the stomach 13 in the embodiment scheme shown in Fig. 3.At this, described chamber 1,2 footpaths are provided with up and down overlappingly, and wherein the chamber 1 of sensing is arranged on coat of the stomach 13 or the esophageal wall and chamber 2 is provided with under lining is gone into the condition in an intermediate layer 16 in case of necessity by chamber 1.Arrange overlappingly up and down by chamber 1,2 and to obtain a pressure condition different with the chamber that is arranged side by side 1,2.Under the situation that chamber 1,2 is provided with up and down overlappingly, in single loop system, there is not liquid to be back to the chamber 1 of sensing from the chamber 2 of constraint appetite according to Fig. 1 and 2, because in two chambers 1,2, have identical pressure, because two chambers are up and down overlappingly between coat of the stomach 13 and back 4.Have only when the chamber 2 of constraint appetite is narrower than the chamber 1 of sensing, when the chamber 1 of sensing moves on to the chamber 2 of constraint appetite, just limit at liquid.Also overcome simultaneously the problem of barometric gradient thus.The active force that two chambers 1,2 are applied on the common boundary face A is F=p*A.Because the area that the chamber 1 of sensing is run on the common edge interface is bigger, so the active force of the chamber 1 of sensing is greater than the active force that has than the chamber 2 of the described constraint appetite of small area of contact.Therefore, the chamber 2 of described constraint appetite has the trend in the chamber 1 of the sensing of being emptied to.Chamber 1 the inside and the appetite width of getting back to sensing in diet end back flow of liquid increase again.
The flexible program with pressure suction type pump according to Fig. 4 need not electric energy.Described chamber 1,2 for example surrounds whole circumference.
Opposite with single loop system according to Fig. 1 and 2, in according to the binary cycle system of Fig. 3 and 4, there is the problem of limitation function for the structure that does not have chamber 1,2.Liquid always moves on to the chamber 2 that retrains appetite and therefore from a deposit chamber 9 the appetite width must be reduced.And in single loop system, have only when chamber 1,2 is provided with abreast, the skew of the chamber 2 of liquid from the chamber 1 of sensing to the constraint appetite just realizes the appetite constraint.If two chamber 1,2 footpaths are provided with up and down overlappingly, the then mobile variation that can not cause the appetite width of the chamber 2 of liquid from a chamber 1 to the constraint appetite.This point only could realize when that chamber that chamber that liquid pumps into takes out than liquid constitutes narrowlyer.Therefore if the chamber of constraint appetite is narrower, then higher and the appetite width is narrower for this chamber of identical amount of liquid.Therefore liquid chamber leniently mobile in the narrow chamber causes the appetite constraint.
Fig. 5 illustrates the axonometric chart of another embodiment of a stomach band, and wherein the chamber 1 of sensing is arranged on the inextensible back 4 along the stomach band circumference abreast with the chamber 2 of constraint appetite.Make the chamber 2 of liquid by auxiliary chamber 3, perhaps deposit chamber 9 of being connected of chamber 2 with the constraint appetite, this auxiliary chamber or lay in the outside that the chamber is positioned at back 4 from chamber 1 pump to the constraint appetite.Described stomach band is around uppermost stomach or esophagus twines and sealing.In the embodiment shown, the part around two chambers 1,2 only occupy respectively.Additionally can be provided with another chamber 18, it neither has the function that sensory function does not have the constraint appetite yet in the adjustable stomach band scope, but in order to make stomach band adapt to corresponding situation.For this reason, the chamber 18 of microscler formation be arranged on above the chamber 1,2 of stomach band and together around and fixing uppermost stomach or esophagus.Described chamber 18 is connected with a gateway (port) 20 in known manner by a corresponding conduit 19, and this gateway is arranged on subcutaneous.Therefore can liquid be imported chamber 18 or realize the adaptive of stomach band from chamber 18 drains by gateway 20.
Fig. 6 a and 6b illustrate the cutaway view of stomach band in chamber 2 zones of constraint appetite according to Fig. 5.In Fig. 6 a, the chamber 2 of described constraint appetite is less filled, therefore chamber 18 is than less pushing coat of the stomach 13 (not shown) according to the situation of Fig. 6 b, the chamber 2 usefulness corresponding liquid of the appetite of constraint described in this situation add fill and therefore chamber 18 be expressed on coat of the stomach 13 or the esophageal wall and cause appetite to retrain thus.Additionally do not participate in self-regulating chamber 18 and can be from the outside realize the best adaptive of stomach bands by this thus by gateway 20.
The sensing function of described stomach band makes it possible to realize a kind of new stomach pacemaker design.Can will be limited to the feeding time to the stimulation of coat of the stomach by one as the combination of the stomach band of working sensor and a pacemaker by electric pulse.By the pacemaker probe correspondingly is positioned in the esophageal sphincter zone of bottom, can play this sphincteral effect of activation and thus erstricted diet pass through.Replace activated chamber, the effect of a structure that provides is played in this restriction on physiology.
