Description
Technical field
This utility model relates to a kind of syringe, specifically a kind of band atomizing syringe of interface that makes up a prescription.
Background technology
We know, along with the development of medical procedure, nasal spray treatment means because risk is low, therapeutic effect is fast, reduce the advantages such as painful, become more and more general treatment means.Clinical typical symptom---rhinitis, influenza vaccines etc., its aerosol Therapeutic Method is accepted by numerous medical personnel, patient.The treatment of nasal spray administration all is modes of using common spray bottle, and one bottle of medicine can use at least one week, even more than one month.During two nasal-cavity administration, need to press spraying nozzle, drug dose according to spray operation the time compression number of shower nozzle substantially measure.During the shower nozzle extruding, because hands strength control ratio is more random, so each dose diversity ratio of spraying is larger.This traditional therapeutic modality produces the topic that is of main three aspects:: one, dosage is uncertain, accurately dosage; Two, two nasal-cavity administration dosage are different, and the effect of drugs of generation is unstable; Three, spraying Reusability, nozzle has that left drug solidifies, antibacterial, impurity etc. are very common phenomenon, and is very unhygienic.Clearly, traditional spray bottle can not satisfy safe and effective treatment theory, also can not satisfy present medical demand.
At present, the atomizing syringe is arranged also on the market, it comprises glass overcoat, push rod, piston, and piston is installed in the push rod front portion, is slidingly matched with the glass outer casing inner wall, and glass overcoat front end is installed a nozzle, and the feather valve with the spiral fluid passage is housed in the described nozzle.Be generally in advance fill medicine in the process that this atomizing syringe uses, in the process of using, pull out the direct medicine injection of helmet and get final product.Be mainly used in the function of drug storage, treatment two aspects, be applicable to store can liquid stable medicine.For lyophilized powder, powder medicated powder etc. some can not liquid stable medicine, this atomizing syringe does not have dispensation apparatus, and is then inapplicable.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure, reasonable is provided, both can be used as the liquid medicine storage device, can be used as again the spraying syringe uses, can conveniently carry out taking out of lyophilized powder etc. and annotate and make up a prescription, the band that can quantitatively, accurately the carry out nasal-cavity administration atomizing syringe of interface that makes up a prescription.
The technical scheme in the invention for solving the above technical problem is: the make up a prescription atomizing syringe of interface of a kind of band, it comprises glass overcoat, push rod, piston, nozzle, dispenser, described piston is installed in the push rod front portion, be slidingly matched with the glass outer casing inner wall, it is characterized in that: described glass overcoat front end fixedly mounts a tapped interface, described nozzle and dispenser are provided with the external screw thread that is connected with interface, nozzle and dispenser respectively by interface detachable and mutually trans-substitution be installed in glass overcoat front end.
Interference fit is connected and fixed between interface described in the utility model and the glass overcoat.
The rear portion engaging of push rod described in the utility model is installed one and is injected limited block, and the described limited block of injecting is positioned at the position of injecting half dose on the push rod.
When this utility model uses, at first dispenser is installed on the syringe glass overcoat front end by interface, the puncture needle of dispenser inserts in the medicine bottle, extracts medicine; Then, take off dispenser, nozzle is installed to syringe glass overcoat front end by interface group; Then nozzle is directly filled in the nasal cavity position, promote push rod, the state of medicinal liquid with spraying penetrated.Contrast prior art, this utility model structure rationally, operation, easy to use both can be used as the liquid medicine storage device, can be used as again the spraying syringe and used, and can conveniently carry out taking out to annotate and making up a prescription of lyophilized powder etc., can quantitatively, accurately carry out nasal-cavity administration.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of this utility model nozzle connection status.
Fig. 2 is the structural representation of this utility model dispenser connection status.
Label among the figure is: 1. nozzle, and 2. spraying stem stem, 3. glass overcoat, 4. medicinal liquid, 5. piston, 6. push rod is 7. injected limited block, 8. interface, 9. dispenser, 10. medicine bottle.
The specific embodiment
From Fig. 1, Fig. 2, can find out, the make up a prescription atomizing syringe of interface of a kind of band, it comprises glass overcoat 3, push rod 6, piston 5, nozzle 1, dispenser 9 etc.Described piston 5 is installed in push rod 6 front portions, is slidingly matched with glass overcoat 3 inwalls, can drive in glass overcoat 3 mobile by push rod 6.Be provided with spraying stem stem 2 in the described nozzle 1, during injection, by nozzle 1 state of medicinal liquid with spraying penetrated.The concrete composition structure of described nozzle 1, spraying stem stem 2, dispenser 9 etc. belongs to prior art, repeats no more.
Characteristics of the present utility model are: described glass overcoat 3 front ends fixedly mount a tapped interface 8.Interference fit is connected and fixed between described interface 8 and the glass overcoat 3.Described nozzle 1 and dispenser 9 are provided with the external screw thread that is connected with interface 8, nozzle 1 and dispenser 9 respectively by interface detachable and mutually trans-substitution be installed in glass overcoat 3 front ends.
The rear portion engaging of push rod 6 described in the utility model is installed one and is injected limited block 7, and the described limited block 7 of injecting is positioned at the position of injecting half dose on the push rod.
When this utility model uses, at first dispenser 9 is installed on syringe glass overcoat 3 front ends by interface 8, the puncture needle of dispenser 9 inserts in the medicine bottle 10, extracts the medicinal liquid 4 of freeze-dried mixed powder etc., finishes the process of making up a prescription, as shown in Figure 2.Then, take off dispenser 9, nozzle 1 is assembled into syringe glass overcoat 3 front ends by interface 8, namely finish the storage of medicinal liquid; Can prepare to carry out medicine injects.As shown in Figure 1.When injection was used, push rod 6 drives injected limited block 7 reaches, and nozzle 1 is directly filled in a nostril, when having injected half dose of glass overcoat inner liquid medicine 4, inject limited block 7 and be stuck in glass overcoat 3 rear ports, restriction push rod 6 moves, the dose of half is injected in a shot; Then will inject limited block 7 and pull out, nozzle 1 is aimed at and is filled in the another one nostril, continues to have injected remaining half medicament in the glass overcoat, is convenient to control dosage, can realize the purpose of two nasal cavity equivalent, quantitative treatment.
This utility model structure rationally, operation, easy to use both can be used as the liquid medicine storage device, can be used as again the spraying syringe and used, and can conveniently carry out taking out to annotate and making up a prescription of lyophilized powder etc., can quantitatively, accurately carry out nasal-cavity administration.
