Abstract
The utility model relates to a slow release drug delivery coating which is characterized by comprising a water-soluble slow release film, wherein multiple drug storage grooves to be filled with drug are formed on the slow release film, the drug storage grooves are densely distributed on the slow release film, and glue for bonding the slow release film is coated on the slow release film around the drug storage grooves. The slow release drug delivery coating provided in the utility model can be used when the release film is removed and the slow release film is rolled and wrapped after the drug storage grooves are filled with drug. For different diseases, drug can also be directly filled in the drug storage grooves and the drug delivery coating can be sealed through the release film in a drug delivery coating production process; and after the release film is directly removed and the slow release film is rolled and wrapped, the drug delivery coating can be used. The slow release film can be made by using hydroxypropyl methyl cellulose as raw materials, the slow release film can slowly dissolve in water, slow drug release can be realized after the drug is rolled and wrapped with the thin film, and the slow release does not need to be taken out after the drug is delivered. Moreover the slow release drug delivery coating is advantaged by simple structure, wide application, and safety and hygiene.
Description
Technical field
This utility model relates to a kind of peplos that can sustained-release administration.
Background technology
Local application is the effective measures of a lot of disease of pharynx for the treatment of.Gargarism, liniment, atomized inhalation, buccal tablet and spray are the main dosage forms of pharyngeal local application.Studies show that medicine too short in the pharyngeal time of staying be the principal element of impact pharyngeal local application curative effect.Existing gargarism, liniment, spray (spray or dust) administration, medicament is pharyngeal directly into the oral cavity, this administering mode medicament dissolution is fast, persistent period is shorter, thereby unsatisfactory curative effect, if repeatedly medication on the one hand brings a lot of inconvenience to the patient, a large amount of external used medicines enter stomach and can cause more side effect on the other hand.Although the buccal tablet continuous action time through special compacting prolongs, and also is nowhere near.Atomizing sucks comparatively desirable, and drug level and persistent period can better be controlled, but uses relative complex, and inconvenient.Given this, need the medicine carrying medium that long, easy to operate, the safety and sanitation of a kind of time that continues medication are provided badly.
The utility model content
In order to address the above problem, this utility model provides a kind of sustained-release administration peplos, it is characterized in that: comprise water miscible release membranes, be formed with on the release membranes a plurality of for filling medicament deposit the medicine groove, described deposit the medicine groove densely arranged on release membranes and the release membranes of depositing medicine groove periphery be coated with the glue that is useful on bonding release membranes.
Further, be coated with mould release membrance on the described glue.
Further, described mould release membrance covers on whole the release membranes, deposits to be filled with medicament in the medicine groove and to be sealed in by mould release membrance and deposits in the medicine groove.
Further, described release membranes adopts the hydroxypropyl methylcellulose raw material to make.
Further, described release membranes is elongated.
Further, the medicine groove of depositing on the described release membranes is equidistantly arranged.
The utlity model has following beneficial effect:
The sustained-release administration peplos that this utility model provides, only needing open behind the filling medicament in depositing the medicine groove first mould release membrance during use can use after with the release membranes wraparound, also can when producing, directly medicament be packed into for disease and deposit in the medicine groove and with the mould release membrance sealing, directly open mould release membrance during use and can use after with wraparound; And release membranes can to adopt hydroxypropyl methylcellulose be that raw material is made, release membranes is slowly dissolving in water, continues medication; This kind sustained-release administration peplos is simple in structure, of many uses, safety and sanitation.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1 is for specifically executing the structural representation of the sustained-release administration peplos of example one.
Fig. 2 is for specifically executing the schematic diagram of the sustained-release administration peplos of example one.
Fig. 3 is for specifically executing the structural representation of the sustained-release administration peplos of example two.
Fig. 4 is for specifically executing the schematic diagram of the sustained-release administration peplos of example two.
The specific embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that this utility model provides in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, shown in Figure 2, a kind of sustained-release administration peplos comprises water miscible release membranes 1, deposits medicine groove 2, forms glue 3, mould release membrance 4 on the release membranes of depositing medicine groove periphery.Release membranes 1 is roughly elongated, adopts the hydroxypropyl methylcellulose raw material to make; Deposit that medicine groove 2 grooves are densely arranged arranges on release membranes and equidistantly; Deposit on the release membranes 1 of medicine groove 2 peripheries and be coated with the glue 3 that is useful on bonding release membranes, mould release membrance 4 covers on the glue; Be formed with the through hole 41 corresponding with depositing medicine groove 2 on this mould release membrance, when mould release membrance 4 covers on the glue 3, deposit medicine groove 2 and be open slot.
The embodiment of specific embodiment one is as follows: when using this kind sustained-release administration peplos, to deposit first medicine groove 2 interior filling liquid or mealy medicines, medicament is opened mould release membrance 4 after filling, is exposed 3 layers in glue, to can use behind release membranes 1 wraparound, 4 of release membranes are pasted together by glue 3, guarantee that medicament does not run off.It is that raw material is made that release membranes 1 adopts hydroxypropyl methylcellulose, and release membranes 1 is slowly dissolving in water, continues medication, and need not after the use to take out again.
With reference to Fig. 3, shown in Figure 4, a kind of sustained-release administration peplos comprises water miscible release membranes 1a, deposits medicine groove 2a, forms glue 3a, mould release membrance 4a on the release membranes of depositing medicine groove periphery.Release membranes 1a is roughly elongated, adopts the hydroxypropyl methylcellulose raw material to make; Deposit that medicine groove 2 grooves are densely arranged arranges on release membranes and equidistantly; Deposit medicine groove interior 2 and be filled with medicament 100; Deposit on the release membranes 1 of medicine groove 2 peripheries and be coated with the glue 3 that is useful on bonding release membranes, when mould release membrance 4 covers on the glue medicament 100 is sealed in and deposits in the medicine groove 2.
The embodiment of specific embodiment two is as follows: when producing this kind sustained-release administration peplos, medicament 100 is packed into to deposit first and also uses mould release membrance 4 sealings in the medicine groove 2, directly open mould release membrance 4 during use, expose glue layer 3, will can use behind release membranes 1 wraparound.1 of release membranes is pasted together by glue, guarantees that medicament does not run off, and it is that raw material is made that release membranes 1 adopts hydroxypropyl methylcellulose, and release membranes is slowly dissolving in water, continues medication, and need not after the use to take out again.
The above, it only is this utility model preferred embodiment, therefore can not limit the scope that this utility model is implemented with this, the equivalence of namely doing according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model patent contains.
