Description

Alimentation composition
Technical field
The present invention relates to a kind of contain as the lipid that can supply with the heat composition of high heat be used as main constituent alimentation composition.More detailed, it is excellent to relate to a kind of emulsion stability, be fit to oral uptake, in pipe is granted any, can be used as the alimentation composition that medicine or diet article provide.
Background technology
At present, the commercially available liquid liquid food and the nutrient major part that are used for granting through pipe are adjusted at 1kcal/mL (g)~2kcal/mL (g) with heat.These alimentation compositions are mostly for can only carrying out the composition of nutritional care (particularly with artificial object in bedfast old age) with it in addition.These usually with each hundreds of mL, be divided in 1 day and grant for several times.
For example, need grant in every day under the situation of 1000kcal,, then can calculate,, need 10 hours, even if the preparation of 2kcal/mL also needs 5 hours for the liquid formulation that is adjusted into 1kcal/mL if grant with the speed of 100mL/h.Therefore hard to imagine with uncommon feed is promptly compared through the situation of oral uptake nutrition, and the needed time of nutrient is significantly elongated.Therefore produce a lot of shortcomings.If carry out illustration, then can enumerate out, (1) owing to be bound to long nutrition and grant, thereby the time of giving exercise therapy is restricted; (2) owing to utilized when the nutrition of pipe nutrition is granted and require certain position, thereby the risk that the disgrace skin ulcer takes place increases; (3) in most cases require nurse, helper etc., nursing staff to confirm the operation that the situation of granting is whether suitable at regular intervals, need the labour for this reason; (4) physiological function such as the passing of blood glucose value, gastric acid secretion state is replied and possibly prepared when managing nutrition, to produce under the situation of microbial contamination with different (5) that caused by common feed; Grant microorganism in the thing possibility of propagation, the risk rising that alimentary toxicosis takes place etc. are arranged.Therefore think and the needed time when seeking to shorten nutrition as much as possible grants, can bring preferred result.
But; Cause the patient that swallows, chew ability and reduce stomach dwindles as following the age to increase old people, by cerebrovascular disease, neuromuscular disease etc., cause under the situation the patient of oral uptake difficulty, the postoperative patient etc., that gastrointestinal function is weak by disturbance of consciousness etc.; Side effect such as GERD, diarrhoea be possibly cause, thereby a large amount of liquid foods or nutrient preferably once do not granted.
As the method that solves with alimentation composition the problems referred to above that produce when long-time or short time grants, can consider that it is low capacity that composition with alimentation composition is prepared into than in the past preparation higher concentration and preparation consumption.Through being prepared into high concentration, make its heat composition that contains abundant amount, through being prepared into low capacity, can alleviate burden to patient and nursing staff.But; As containing normally used comprehensive trophic component, being the preparation of protein, carbohydrate, lipid, mineral, vitamin; With the angle of its high concentrationization from preparation and ingredient stability; Be difficult, thus we can say preferably process mainly contain lipid, heat composition supply specialization the form of additional liquid.
As said high concentration and low capacity, with the supply of heat composition is that the per os enteral nutrition of purpose is used lipomul, and commercially available マ イ Network ロ リ ピ ッ De (" Microlipid " is arranged; ノ バ Le テ ィ ス society, registered trade mark).It is the lipid composition of safflower oil 100%, the liquid emulsion preparation of 4.5kcal/mL (lipid 50g/100mL), and its form is the vial of putting into through the screw lid sealing, and capacity is 89mL/.Aforementioned emulsification preparation is as the preferred fluid composition of heat composition supply purposes, but not special consideration fatty acid composition is not talkative good as the utilization ratio of heat composition; Carry out when pipe is granted, need be via other container, thereby from the viewpoint of health aspect, convenience; Poor availability does not have sufficient emulsion stability, easy separation during room temperature preservation; The capacity of one packing unit is many, low capacity is unhygienic etc. when using, the very preferred preparation of can not saying so.
On the other hand, as the lipomul that can easyly be used for granting, disclose preparation and avoided the technology (patent documentation 1,2) of liquid level in fact with the Prefilled syringe that contacts (Pre-filled Syringe) preparation of oxygen through pipe.But these technology only provide and are suitable for the preparation technique of granting through vein specially, do not relate to being suitable for through stomach or enteral nutrition.Disclosed in addition fill volume from the viewpoint of heat composition supply, is not carried out abundant detailed survey for number mL.For being the medicine preparation of representative with commercially available lipomul イ Application ト ラ リ ピ ッ De (テ Le モ Co., Ltd., registered trade mark), イ Application ト ラ リ Port ス (Otsuka Pharmaceutical Factory, Inc., registered trade mark); Be purpose also to grant through vein; Good aspect preparation stabilities such as juice secretion; But the lipid concentration that contains is 10% or 20%; With the LCFA is main constituent, and from the viewpoint of " preparation that contains the lipid of high concentration ", it is ideal through stomach or enteral nutrition preparation to say so.
In addition, as the technology of the preparation that relates to lipomul, patent documentation 3~5 has open.But; These mainly disclose the technology of about preparation stability, particularly being controlled the inhibition effect that is separated that causes by particle diameter; But, still, openly do not relate to the preferred technology that nutritional labeling is granted not about the investigation of lipid concentration from the viewpoint of granting of heat composition.Be combined with glucose, glycerol as emulsion stabilizer in the aforementioned in addition lipomul, according to its use level, by dispenser's state, per os and the risk that produces the diarrhoea problem is arranged when intestinal is granted.Therefore, be used to carry out technology, inadequate information disclosure is only arranged through stomach or enteral nutrition as ideal.And then owing to infer aforementioned lipomul for to grant through vein, the obstruction of the filter when granting should make the mean diameter of emulsified particle little, needs perhaps repeatedly emulsifying of high pressure during manufacturing.
In addition, as the technology of the external member that relates to liquid nutritional composition, have open in the patent documentation 6~8.These technology are characterised in that makes each nutritional labeling, preserve with isolating state separately; But not the external member that mainly is conceived to the supply of heat composition; Not about can low capacity and high concentration grant, particularly as the research of the raising of the utilization ratio of the lipid of heat composition.In addition, in the said external member, need mix multiple liquor during use, this operation is very miscellaneous sometimes.
That is, about containing the alimentation composition of the high lipid of high concentration and utilization ratio as single agent formula (a drug formula) of heat composition and emulsion stability excellence, up to the present not open very gratifying compositions.
