Abstract
A long-acting nasal cavity medicine-waiting framework belongs to an apparatus suitable for making medicines into special shapes. The skeleton is made of non-toxic plastic (such as polyethylene) and silicon rubber, and is made into microporous ball, cylinder and conical plug with central through hole for storing medicine liquid and keeping its effect for a long time.
Description
A kind of long-acting nasal cavity is waitd upon the medicine skeleton.Belong to and be applicable to the apparatus of medicine being made special shape.
Nasal cavity is waitd upon the form of medicine to drip at present, does not still have and waits upon the medicine apparatus especially.Drop flows into the oral cavity after splashing into nasal cavity easily, makes the people feel the abnormal flavour discomfort.Though the aqueous drop is scattered in the nasal cavital mucus easily, action time is short, and oiliness drop penetrance is poor, when consumption is too much, causes " lipid pneumonia easily." no matter be water preparation or oil preparation, often need multiple dosing, the patient has the suspicion of inconvenience more.
The purpose of this utility model provides a kind ofly can store medicinal liquid, does not influence breathing again, once waits upon medicine and can keep the long-acting nasal cavity of drug effect the long period and wait upon the medicine skeleton.
Solution of the present utility model is that the flexible material of silicone rubber and so on is made micropore ball, the cylinder with central through hole, nasal cavity shape circular cone thromboembolism with non-toxic plastic (as polyethylene).As pharmaceutical carrier, it is immersed in the drop, during use it is filled in nasal cavity, as long as the straight-through atmosphere of central through hole does not influence breathing.
This utility model manufacturing process is simple, and is clinical extremely easy to use, once waits upon medicine and can the long period keep drug effect.Because micropore is stored medicinal liquid, it is even to wait upon medicine, can avoid clinical because inhomogeneous " peak valley phenomenon " that causes of medication.
Accompanying drawing 1 is the micropore ball thromboembolism sketch map with central through hole.
Accompanying drawing 2 is the micropore cylinder thromboembolism sketch maps with central through hole.
Accompanying drawing 3 is the micropore nasal cavity shape circular cone thromboembolism sketch maps with central through hole
Enforcement of the present utility model can be with the diameter of micropore ball, the external diameter of micropore cylinder, the maximum outside diameter of micropore nasal cavity shape circular cone thromboembolism is controlled at 6～8mm, the internal diameter of central through hole is controlled at 2～3mm, the greatest length of cylinder, circular cone is controlled at 15～20mm, drug level and the release Fick law required according to receptor are determined the degree of crook in the required aperture of skeleton, porosity and hole to adopt existing foam process manufacturing.
Claims (2)
1, a kind of long-acting nasal cavity is waitd upon the medicine skeleton, belongs to being applicable to the apparatus of medicine being made special shape, it is characterized in that this skeleton is the flexible thromboembolism of micropore ball, cylinder, nasal cavity shape circular cone with central through hole.
2, wait upon the medicine skeleton according to a kind of long-acting nasal cavity of claim 1, it is characterized in that the maximum gauge of micropore ball, cylinder, nasal cavity shape circular cone is 6～8mm, the internal diameter of central through hole is 2～3mm, and the greatest length of circular cone is 15～20mm.
