Detailed description of the invention
Be described in detail this utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
Fig. 1 to Fig. 6 illustrates several preferred version of the present utility model, and this utility model is a kind of capsule swallowed, and comprises capsule, pill or agglomerate, is called as capsule at the remainder of presents.
As illustrated in fig. 1 and 2, this capsule may be made up of following a kind of, two kinds or all structures.
A shell-like structure 1 comprising one or more layers top layer, dissolving that can be very fast after this shell-like structure 1 and some liquid (gastric acid that the stomach of such as people is secreted) contact or fragmentation.
An internal structure is expansible support shape or the network structure that the sack of a liquid permeable or the folding film of extensile sacculus 2,4, sack with holes or sacculus and accommodate one or more core materials.In a preferred approach, the diameter after the expansion of this structure is 3 ~ 10 centimetres, can effectively prevent this structure from entering small intestinal by pylorus like this.This internal structure can be dissolved or fragmentation within the time (such as one day or one week) of one longer.This internal structure can be done smaller or larger, and its shape is not limited to spherical.According to different design requirements, this internal structure can adopt arbitrary shape, as shown in Figure 3 there is the extensile film of loose structure and the scheme of sack, its hole makes the liquid of gastric enter into expansiveness material.Fig. 4 have employed cancellated scheme, and this structure makes the liquid of gastric can enter into expandable material easily.Fig. 5 wraps up the network structure of core material, and this core is made up of several mushroom fragment, and these fragments are gathered by network structure and constrained in together.
In a preferred approach, the core material 3 that expandable stent shape or network structure are wrapped up can be expandable biomaterial or non-biological material.It is to ensure that it still can flock together after inflation and be limited in certain region that core material 3 is wrapped up by expansible support shape or network structure.Core material 3 can be dried Auricularia, because dried Auricularia with water or other liquid comes into contact after can there is significant expansion, this core material 3 also can be can occurring significantly to expand and there is biomaterial or the non-biological material of certain hour at gastric of other in addition.
Test verified, Auricularia is after immersion water or acidic liquid, and under body temperature, its volume can expand more than 10 times in 5 ~ 10 minutes.Because dried Auricularia is loosely organized, be not connected mutually between every sheet dried Auricularia or adhere to, this just requires that the support of parcel core material or network structure can ensure that dried Auricularia (or other loosely organized inflatable core materials) still can gather together upon inflation, after avoiding its dispersion, slip into small intestinal by pylorus.Core material 3 can be that single material also can be made up of multiple material.And if the inflatable core material selected still can keep certain continuous structure and shape after inflation, that just can save support or the network structure of parcel core material.
The function of this utility model capsule and other existing capsule, structure and content are all completely different.Most of capsules on sale are in the market all medical and comprise specific medicine, and after capsule dissolves or fragmentation, the medicine that inside comprises can be discharged in stomach or intestinal.The capsule of other types can also be built-in for special measurement electronic original part.The Novel capsule that this utility model relates to is very special, because it has several functional part (layer) and its function makes the core material of parcel in capsule get up at distended stomach and not measure especially to discharge in certain material to digestive tract or carrying out certain to digestive tract as other capsules.
In a preferred approach, the support or the Web materials that wrap up core material 3 must at stomach through degrading after a period of time voluntarily.In other words, the material wrapping up core can dissolve or fragmentation after through after a while (such as one day or one week).According to the difference of lapping selected, degradation time may shorter also may be longer.Such as, internal structure can be dissolved after one week, and the core that it is wrapped up is released to gastric.Because core material may include the biomaterial of dried Auricularia and so on, and may along with the dissolving of lapping by partial digested, so after these biomaterials are released to gastric, can also intestinal be entered by pylorus and be digested further there.At this moment, user just needs the clothes next one or multiple capsule to carry out effect of maintaining treatment.This capsule can also comprise a compact transmitter, so that the data of the gastrointestinal location residing for capsule to be sent to the data recording equipment of outside, or provide in other way about the important information of core material in stomach or other intraorganic states.
At present, several dissimilar capsule being built-in with electronic component has been applied patent and has started selling.These capsules can in also monitoring pressure and the pH value change simultaneously of the inner serialograph of gastrointestinal tract.Unique distinction of the present utility model is that the signal projector that capsule includes will be completely different from other existing capsule products.The built-in signal projector (or position sensor) of the capsule that this utility model relates to is only for launching or providing the positional information of capsule whether the position of capsule is also in stomach to help user to judge.
The material of capsule structure can be selected according to the difference of the degradability in different liquid.Such as, if capsule structure have passed pylorus for accidental cause and enters small intestinal epimere, this internal structure preferably can in the alkaline environment of small intestinal epimere fast degradation.
In addition, capsule structure can also be made up of the material with adhesive.So just can be less than 3 centimetres at single capsule expanded diameter and likely through pylorus time, carry out adhesion become an enough large syndeton by taking one or several capsule more, thus ensure that all capsules can rest on gastric.In an alternative prioritization scheme, the internal structure of each capsule will comprise physical connector (such as thread or adhesive material) to ensure that multiple expansion structure can adhere to each other effectively.
In the special scheme that this utility model relates to, the internal structure of capsule contains a device that can stretch voluntarily, as shown in Figure 6, can convert ring-type or fenestral fabric to after being placed in gastric portion.This structure is connected to form the passage that food can be allowed across and into small intestinal with the light-wall pipe of a section or multistage length.Ring-type or fenestral fabric will be placed in stomach, and coupled sheet-metal duct 8 will extend to little enteral.The suitable length of sheet-metal duct 8 is 20-80 centimetres, but may be shorter or longer in other scheme.The circulus be connected with sheet-metal duct 8 can be memorial alloy (or SMART METALS), can Self-bouncing keep certain shape after entering stomach, and this shape can effectively stop it to slide into little enteral.Can be connected by the structure of the expansible structure of a shelf-like (or latticed) 7 or other any types between sheet-metal duct 8 and the intelligent elastomeric material of ring-type 6, or sheet-metal duct 8 is directly connected with the intelligent elastomeric material of ring-type 6.This syndeton can include barb, bar, spring or other irregular surface structures, to ensure that it can not be slipped to little enteral.
First the device that this utility model relates to is mainly used in stomach, as shown in Figure 7, but also can be used for any position of intestinal afterwards, such as pyloric cap etc.The size of device can be determined according to the size of the concrete organ holding this device.Above-mentioned scheme and figure are only some examples, so a lot of variant device will be developed successively.
Application example of the present utility model: someone determines fat-reducing, but he/her does not wish to be undertaken by the mode of surgical operation or endoscope.So the slimming capsule that his/her choice for use this utility model relates to.He/her has read over the description of this slimming capsule to avoid the occupation mode of mistake.Then he/her ate a meal and had taken one or several slimming capsules subsequently.Under clothes after capsule, he/her has drunk again a large amount of water, and capsule enters stomach 10 through esophagus 9, fully expands as soon as possible in stomach 10 to help the core material of slimming capsule.Subsequently, broken capsule shell also dissolves completely in stomach 10; And core material to be blocked by pylorus 11 after expanding and cannot enter small intestinal 12.The process that core material expands may need a few second to half an hour.Adopt dried Auricularia to test as core material, result demonstrates core material under body temperature, is aided with enough water, only needs within 5-10 minutes, just may be expanded to 90%-100% of its final volume.After core material expands, will feel at the gastric generation satiety of user or other and maintain the longer time.Due in most of preferred version, the shell of capsule, internal structure even core material all can be digested and assimilated, and therefore user must after some time, such as second day or next week again take this slimming capsule.If but the internal structure of capsule, core material or length thin tube can not be digested and assimilated, that just must remove this device by the endoscopic surgery of hospital or clinic after a certain time.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
