Abstract
The utility model relates to an otolaryngological department used spray machine, which comprises a medicine bottle with the downwards concave at the middle of the inner bottom, a pipette, and a solution storage cylinder, wherein the solution storage cylinder is transversely fixed on a bottle cover at the upper end of the medicine bottle; a piston matched with the solution storage cylinder is inserted in the solution storage cylinder; a spray pipe is communicated with the tail-end of the solution storage cylinder; a flow regulator is arranged on a position, positioned at one end of the solution storage cylinder, of the spray pipe; the upper end of the pipette is communicated with a hollow inner chamber close to the tail end of the solution storage cylinder, and is hinged with a one-way baffle sheet opened towards the hollow inner chamber of the solution storage cylinder, and the lower end of the pipette is connected with a hollow metal ball; through-holes are distributed in the metal ball wall. According to the spray machine, as the one-way baffle sheet is arranged at the upper end of the pipette, the backflow of liquor can be effectively prevented; when the liquor inside the medicine bottle is less, surplus liquor can still be sucked into the solution storage cylinder through the metal ball to conduct spray without affecting the using of the spray machine; the spray machine has the advantages that the angle can be adjusted freely during spraying, the spray machine is not affected by the amount of the liquor, and the using is convenient.
Description
Technical field:
This utility model relates to a kind of medical appurtenance, relates in particular to a kind of department of otorhinolaryngology medicinal sprayer.Background technology:
Medicinal sprayer is department of otorhinolaryngology a kind of instrument of adding medicine to for patient commonly used, its be mainly in auditory meatus, nasal cavity or these darker positions of throat are sprayed medicine.In the process of spray medicine, medical personnel need to constantly adjust according to the posture of the position of spraying medicine and patient body the angle of medicinal sprayer.And the lower end of pipette in existing medicinal sprayer medicine bottle is usually located at the bottom of medicine bottle, when medicinal sprayer is squeezed or when medicinal liquid is less after the inclination certain angle, pipette all can't be drawn medicinal liquid, thereby can't be sprayed medicine, uses very inconvenient.
The utility model content:
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, and a kind of easy to operate, result of use good, reliability is higher department of otorhinolaryngology medicinal sprayer is provided.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of department of otorhinolaryngology medicinal sprayer, comprise medicine bottle, pipette and the liquid storage cylinder of the middle part of inner bottom part to lower recess, wherein, described liquid storage cylinder laterally is fixed on the bottle cap of medicine bottle upper end, be inserted with the piston matched with it in liquid storage cylinder, piston is comprised of core bar and the rubber stopper that is fixed on core bar one end, and the end of liquid storage cylinder is communicated with medicine spraying tube, on the medicine spraying tube that is positioned at liquid storage cylinder one end, is provided with flow regulator; Described pipette is flexible pipe, and its upper end is connected and is hinged with the unidirectional catch of opening to the liquid storage cylinder hollow cavity with the hollow cavity near the liquid storage cylinder end, and lower end is connected with a hollow metal sphere, on the metal ball wall, is distributed with through hole.
The beneficial effects of the utility model are: this utility model, owing in the pipette upper end, being provided with unidirectional catch, can effectively prevent the backflow of medicinal liquid; And when the medicinal liquid in medicine bottle is less, still can be drawn in liquid storage cylinder by remaining medicinal liquid and be sprayed medicine by metal ball, can not affect the use of medicinal sprayer, have advantages of when the spray medicine and can arbitrarily adjust angle and not be subject to the how many impact of amount of liquid medicine and easy to use.
The accompanying drawing explanation:
The structural representation of Fig. 1 this utility model embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
A kind of department of otorhinolaryngology medicinal sprayer of the present utility model, comprise medicine bottle 1, pipette 2 and the liquid storage cylinder 3 of the middle part of inner bottom part to lower recess, described liquid storage cylinder 3 laterally is fixed on the bottle cap of medicine bottle 1 upper end, be inserted with the piston 4 matched with it in liquid storage cylinder 3, piston is comprised of core bar and the rubber stopper that is fixed on core bar one end, the end of liquid storage cylinder 3 is communicated with medicine spraying tube 5, on the medicine spraying tube 5 that is positioned at liquid storage cylinder 3 one ends, is provided with flow regulator 8; Described pipette 2 is flexible pipe, pipette 2 should be tried one's best near the bottommost of medicine bottle 1, its upper end is connected with the hollow cavity of liquid storage cylinder 3, and the upper end of pipette 2 is near the end of liquid storage cylinder 3, while adopting this structure to guarantee to use, in the process of push-and-pull piston 4, pipette 2 is connected with the hollow cavity of liquid storage cylinder 3 all the time; The upper end of pipette 2 is hinged with the unidirectional catch 6 of opening to liquid storage cylinder 3 hollow cavities, and unidirectional catch 6 can make medicinal liquid flow in the hollow cavity of liquid storage cylinder 3 by pipette 2, and can't reflux; The lower end of pipette 2 is connected with a hollow metal sphere 7, on metal ball 7 walls, is distributed with through hole, and metal ball 7 can be freely movable at medicine bottle 1, in the time of can guaranteeing to remain a small amount of medicinal liquid in medicine bottle 1, still the residue medicinal liquid can be drawn in liquid storage cylinder 3.
Department of otorhinolaryngology of the present utility model with medicinal sprayer in use, at first medicine bottle 1 is upright, then pull out in the hollow cavity that piston 4 makes liquid storage cylinder 3 and form negative pressure, because hollow cavity, pipette 2 and medicine bottle 1 three of liquid storage cylinder 3 is communicated with, under the effect of negative pressure, the unidirectional catch 6 of the upper end of pipette 2 can upwardly open, and the medicinal liquid in medicine bottle 1 also can flow in liquid storage cylinder 3 simultaneously.After the amount of liquid medicine of liquid storage cylinder 3 interior storages reaches required dosage, the end of medicine spraying tube 5 aim at is needed to spray medicine position, then promote piston 4 the medicinal liquid ejection is got final product.When promoting piston, unidirectional catch 6 is closed downwards due to the malleation that is subject to medicinal liquid, thereby the upper end of pipette 2 is covered, and has effectively prevented the backflow of medicinal liquid.Because the medicinal liquid that will spray has been stored in liquid storage cylinder 3, therefore in the process of spray medicine no matter medical personnel how to adjust the angle of medicinal sprayer, even medicinal sprayer is inverted, medicinal liquid still can normally spray.When the medicinal liquid in medicine bottle 1 is less, this Otorhinolaryngologicmedicine medicine sprayer still can be drawn in liquid storage cylinder 3 and the spray medicine carried out by remaining medicinal liquid by metal ball 7, can not affect the use of medicinal sprayer.And be provided with flow regulator 8 on medicine spraying tube 5, can effectively control the amount of liquid medicine of ejection.
The above, it is only preferred embodiment of the present utility model, be not this utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
