Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of quantitatively device of intranasal brain-targeted drug delivery and drug storage
Container.
Background technique
Blood-brain barrier is one layer of natural barrier between body circulation and central nervous system, is playing barrier action,
While stopping pathogenic microorganism and harmful substance to enter brain, also counteract that many drugs enter central nervous system and play treatment work
With.Existing many medications, such as through cranium in-situ injection, through subarachnoid injection, because of traumatic strong, operating technology
It is required that the reasons such as height, it is difficult to be widely used in clinical patients.
The branched ending of olfactory nerve is distributed in olfactory mucosa, as one of 12 pairs of cranial nerves, exists so that external substance passes through
Olfactory nerve and its related pathways enter brain in the presence of possible.In addition, the distribution of nasal cavity Zhong Yiyou trigeminal neuralgia branch, and schneiderian membrance exists
Widely distributed blood vessel and lymphatic vessel can be linked up with encephalic, therefore drug intranasal enters brain and can avoid blood-brain barrier and maximum journey
Degree ground reduces administration difficulty.
Current nose administration device is ripe day by day in terms of the dispersion of drug, transmission and distribution.It is clear from simple nasal cavity
Watering can, nasal spray are washed, to the application of ultrasonic atomizatio, osmotic pumps on nose administration device, distribution of the drug in nasal cavity is
It can achieve widely distributed and finely dispersed purpose.However most device Shortcomings in terms of drug storage.
Traditional direct nasal drip is using existing mixed or premix the direct collunarium of drug, it is advantageous that can neatly basis
The demand of user adjusts dosage, however configuration drug is needed before collunarium, and the work of medical staff is increased in clinical use
Amount, and for patients, complicated operation reduces the compliance used.
The integrated design of intranasal drug and device is common in liquid spray, osmotic pumps, ultrasonic atomizing device etc., administration
Convenient, drug is uniformly mixed, and can effectively improve the therapeutic effect of nose administration.And the part of the not anti-backflow of many devices,
It is directly linked up with the external world, increases the rotten possibility of drug contamination, reduce drug uses validity period.And nasal cavity is to have collarium
Border, the device, which is used for a long time, the risk for causing secondary infection.And most integrated apparatus are difficult to dismantle, therefore clean the barrier of nursing
Hinder the generation for also resulting in pollution.
To solve the above problems, utility model device by detachable apparatus and premix drug separate, and by drug according to
Common or recommended dose is filled in special drug reservoir, reaches simple, efficient, quantitative, clear by being applied in combination for the two
The purpose of clean administration.
