Abstract
The utility model discloses a kind of nasal-cavity administration pipes of via intranasal application administration, including the administration pipe fitting being connected to syringe and the delivery tube hose for delivering drugs to deep nasal cavity；One end of the delivery tube hose is connecting pin, and the connecting pin and delivery tube fittings are simultaneously integrally formed；The other end of the delivery tube hose is intervention end, and the intervention end round end structure is provided with dosing holes on the side wall for intervening end 2-4mm；From outside to inside, the diameter in section is gradually reduced the dosing holes.Technical solutions of the utility model have the advantages that the cell transplantation for entering central nervous system, and via intranasal application administration mode compares traditional traumatic administration mode, can mitigate patient suffering, reduce the damage of patient, to reduce the risk of patient；Nasal-cavity administration pipe can go deep into nasal cavity, and when administration can reduce drug loss, improve the efficiency of nasal-cavity administration；The internal diameter of nasal-cavity administration pipe is small, and drug loss is small, suitable for cell nasal-cavity administration and other need the drug of low dosage nasal-cavity administration.
Description
Technical field
The utility model relates to a kind of nasal-cavity administration pipe, specially a kind of nasal-cavity administration pipe of via intranasal application administration belongs to doctor
Treat equipment technology field.
Background technique
Cell transplantation plays a significant role in neurodevelopment and reparation damaged nerve tissue.Cell transplantation is reparation and generation
For the effective ways of injured cerebral tissue, partial loop and function can be rebuild, for treatment neurodegenerative disease and nervous centralis
System injury disease has important clinical meaning.
Cell transplantation at present enters central nervous system, and there are mainly two types of modes: lumbar puncture subarachnoid injection and head
Portion's drilling injection.The former wound is small, the time is short, therapeutic domain is extensive, but still has certain operation difficulty and risk；The latter is in head
It pushes up and bores one to two apertures on skull, then transplant cells into brain tissue, operation difficulty and risk are larger.
Blood-brain barrier be drug through it is peripherally administered enter brain treatment central disease main bottleneck, especially treatment brain
The cell products of disease.It is located at the neurogenic disease of brain for therapeutic purpose, head drilling injection is at high cost, has wound, side
Method is cumbersome, has security risk.
Nasal cavity is the cell administration approach of more suitable brain diseases, but cell products are different from conventional medicament how
It improves operational efficiency and administering effect is a significant challenge.
Utility model content
The purpose of this utility model is to provide for a kind of nasal-cavity administration pipe of via intranasal application administration, to solve the prior art
The above problem.
A kind of nasal-cavity administration pipe of via intranasal application administration, it is characterised in that: including the administration pipe fitting that is connected to syringe and
Deliver drugs to the delivery tube hose of deep nasal cavity；One end of the delivery tube hose be connecting pin, the connecting pin with
Delivery tube fittings are simultaneously integrally formed；The other end of the delivery tube hose is intervention end, and the intervention end is round end
Structure is provided with dosing holes on the side wall for intervening end 2-4mm；The dosing holes from outside to inside, the diameter in section by
It is decrescence small.
The maximum diameter of the dosing holes is 0.1-6mm, preferably 3mm；Diameter is 0.1-3mm at minimum, excellent
Choosing is 0.5mm.
The length of the delivery tube hose is 30-100mm, preferably 55mm；Outer diameter is 1-5mm, preferably
2mm；Internal diameter is 0.1-3mm, preferably 0.5mm.
The internal diameter of the administration pipe fitting is 4-6mm, preferably 4.5mm.
The nasal-cavity administration tube material is one kind of medical macromolecular materials, preferably medical polyurethane.
The nasal-cavity administration pipe hose answers surface smooth, slightly soft, stimulates nasal cavity small.
Can be set on the outer wall of the administration pipe fitting it is several play it is anti-skidding, reinforce and it is easy to use the effects of
Transformation, be such as provided with convex stupefied.
Technical solutions of the utility model have the advantages that
1, for entering the cell transplantation of central nervous system, via intranasal application administration mode traumatic gives prescription compared to traditional
Formula can mitigate patient suffering, reduce the damage of patient, to reduce the risk of patient；
2, nasal-cavity administration pipe can go deep into nasal cavity, and when administration can reduce drug loss, improve the efficiency of nasal-cavity administration；
3, the internal diameter of nasal-cavity administration pipe is small, and drug loss is small, suitable for cell nasal-cavity administration and other need low dosage
The drug of nasal-cavity administration.
