Abstract
The utility model provides a nose micro jet dosing connector which comprises a double-cavity catheter, a rotational flow nozzle, a spiral connector and conical sponge. The rotational flow nozzle sleeves the upper end of the double-cavity catheter, the spiral connector sleeves the lower end of the double-cavity catheter, the conical sponge sleeves the outside of the rotational flow nozzle, the lower end of the conical sponge clings to the spiral connector, an inner plug is arranged between the upper end face in the rotational flow nozzle and the upper end of the double-cavity catheter, and the inner plug is an inverted butt square vertebral body. The nose micro jet dosing connector is matched with an injector in use, capable of spraying liquid medicine under high pressure to enable the liquid medicine to be in the atomizing state capable of being absorbed by a nasal cavity mucous membrane, high in dosing accuracy, convenient to operate, good in patient adherence, high in production utilization rate, quick in effect and especially applicable to children patients.
Description
Technical field
This utility model relates to the micro-spray administration of a kind of nose joint.
Background technology
Conventional administering mode mainly contains at present: oral, and intramuscular injection, intravenous injection etc., but all there are separately some shortcomings in existing mode, as the state of some sufferer is not suitable for using; Absorb randomly slowly, be easily subject to gastrointestinal impact; Gastrointestinal is had to harmful effect, or gastrointestinal there is destruction to some drugs.Or there is operation easier, application risk is large, the increasing of iatrogenic disease.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, the micro-spray administration of a kind of nose joint is provided, be used in conjunction with syringe, medicinal liquid under high pressure can be sprayed, the spray pattern that formation can be absorbed by nasal membrane, administration precision is high, easy to operate, patient compliance is good, and production utilizes high, instant effect, is particularly suitable for child's sufferer.
In order to solve the problems of the technologies described above, this utility model provides following technical scheme:
The micro-spray administration of a kind of nose joint, comprise double channel catheter, swirl flow nozzle, screwed union and conical sponge, described swirl flow nozzle is sleeved on the upper end of described double channel catheter, described screwed union is sleeved on the lower end of described double channel catheter, described conical sponge is sleeved on the outside of described swirl flow nozzle, described screwed union is close in its lower end, is provided with plug between described swirl flow nozzle inner upper end face and the upper end of described double channel catheter, and described interior plug is inverted butt side vertebral body.
Further, in described double channel catheter lumen pore, be filled with an one metal wire.
Further, the longitudinal cross-section of interior plug is regular polygon.
The micro-spray administration of a kind of nose of this utility model joint, is used in conjunction with syringe, medicinal liquid under high pressure can be sprayed to the spray pattern that formation can be absorbed by nasal membrane, administration precision is high, easy to operate, and patient compliance is good, production utilizes high, and instant effect is particularly suitable for child's sufferer.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation this utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the micro-spray administration of a kind of nose of this utility model joint;
Fig. 2 is the schematic top plan view of the swirl flow nozzle of the micro-spray administration of a kind of nose of this utility model joint.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation this utility model, and be not used in restriction this utility model.
As shown in Figure 1, 2, the micro-spray administration of a kind of nose joint, comprise double channel catheter 1, swirl flow nozzle 2, screwed union 3 and conical sponge 4, swirl flow nozzle 2 is sleeved on the upper end of double channel catheter 1, screwed union 3 is sleeved on the lower end of double channel catheter 1, and conical sponge 4 is sleeved on the outside of swirl flow nozzle 2, and screwed union 3 is close in its lower end, between swirl flow nozzle 2 inner upper end faces and the upper end of double channel catheter 1, be provided with in one and fill in 5, interior plug 5 is inverted butt side vertebral body.
In a lumen pore of double channel catheter 1, be filled with an one metal wire 6, reduce the flow that medicinal liquid passes through, bending tinsel changes spray medicine angle when needed simultaneously.
The longitudinal cross-section of interior plug 5 is regular polygon, and the present embodiment adopts regular hexagon.
Operation principle: be used in combination with common disposable syringe, injector head connects the tail end of screwed union, when syringe is by behind medicinal liquid fill nipple inside, medicinal liquid enters an open tract of double lumen tube with higher speed under thrust, in clashing into, after plug, from the side of interior plug, enters swirl flow nozzle by tract, from three direction screw shower nozzle center diffluences, because the space of shower nozzle inside is minimum, therefore medicinal liquid, still with rotation mode ejection, and falls apart into the vaporific state of minimum medicine.
The micro-spray administration of a kind of nose of this utility model joint, is used in conjunction with syringe, medicinal liquid under high pressure can be sprayed to the spray pattern that formation can be absorbed by nasal membrane, administration precision is high, easy to operate, and patient compliance is good, production utilizes high, and instant effect is particularly suitable for child's sufferer.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, although this utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
