Description
technical field:
This utility model relates to medical apparatus and instruments, particularly a kind of tear stains flusher.
background technology:
Lacrimal passage (being tear stains) comprises lacrimal point, lacrimal ductule, lachrymal sac and nasolacrimal duct.Lacrimal point is each one up and down, is positioned on the mamillary protuberance that alkali edge adjoins end.Upper lacrimal point descends lacrimal point position slightly inner.Lacrimal point displacement often causes the tear disease of overflowing.Lacrimal ductule is the tubule connecting between lacrimal point and lachrymal sac, point superior canaliculus and lower lacrimal canaliculi.Each dacryocanalicular lateral part first becomes vertical direction with alkali edge, is then close in right-angle steering, and two lacrimal ductules merge into tear house steward, are then opened on lachrymal sac top.Lachrymal sac is a film capsule, is positioned at the fossa for lacrimal sac of Medial Orbital Wall front lower place.Lachrymal sac upper end is closed into a speech end, about the interior 3 ~ 5mm place, top that adjoins.Divide a word with a hyphen at the end of a line as nasolacrimal duct in lower end.Lachrymal sac is about 12cm, wide 04 ~ 07cm.The muscle fiber of orbicularis oculi holds lachrymal sac and lacrimal ductule, and collapsible and expansion lachrymal sac, impels tear to discharge.Nasolacrimal duct is the film pipe that connects lachrymal sac lower end, and top is embedded in bone tube chamber, and bottom is tapered and enters in the mucosa of nose lateral wall, is opened on the lateral wall of inferior nasal meatus.Because nasal mucosa and nasolacrimal duct mucosa continue mutually, therefore nasal cavity inflammation can be to vertical spread to nasolacrimal duct.Syringing of lacrimal passages is to dredge by liquid being injected to lacrimal passage the operating technology that its different parts blocks, and can be used as diagnostic techniques, can be used as again Therapeutic Method.The operation of prior art is used traditional injection needle, and when operation, as shown in Figure 1, Fig. 1 is the operation chart of flushing tear stains of the prior art.Existing injection needle is by syringe 1, attachment cap 2, syringe needle 3, extension 4 form, attachment cap 2 is pegged graft and is fixed on the pars papillaris of syringe 1, the end of syringe needle is connected with extension 4, being inserted in tear stains of extension, rinses operation, when operation, push eyelid aside with thumb and forefinger, in the interior portion that adjoins, the extension of syringe needle 4 is inserted to lacrimal point.Dark about 1.5-2mm, then rotates 90.Make needle point towards nasal side, just needle point slowly advance along lacrimal ductule, as non-resistance can advance 5 ~ 6mm.In pipe, inject liquid, firmly evenly, suitably.When flushing, as resistance is larger, there is adverse current or flow out from another lacrimal ductule, representing obstructed lacrimal passage.The direction of the different parts block liquid adverse current of lacrimal passage is also different.In practical operation, push the operation of eyelid aside, patient has the trend of closing one's eyes naturally, and easily hands cunning causes slippage, and the closure of eyelid easily causes intubation defeat and then causes and rinse unsuccessfully, even eyeball is damaged.And traditional syringe conventionally can only once flushing, in running into tear stains and stopping up, cannot continue fluid infusion.In view of this technical problem, need to occur a kind of simple in structure, easy to use, control eyelid fixing firmly, facilitate a kind of tear stains flusher of fluid infusion.
summary of the invention:
The purpose of this utility model is to overcome the shortcoming existing in prior art, provides a kind of simple in structure, easy to use, control eyelid fixing firmly, facilitate a kind of tear stains flusher of fluid infusion.
To achieve these goals, this utility model provides a kind of tear stains flusher, comprise syringe and support eye device, on syringe, be provided with attachment cap, syringe needle and extension, peg graft fixing between attachment cap and the end of syringe, attachment cap and syringe needle, extension are one-body molded during fabrication, wherein, on the wall of syringe needle, be further provided with liquid supplementation pipe, between one end of liquid supplementation pipe and syringe needle, be fixedly connected with, the other end is provided with connection-peg; On support eye device, be provided with fastening plate and strut arm, strut arm and be Y word shape, the integrated screw that is provided with in both sides of fastening plate, strut between the lower end of arm and screw and be threaded, the upper end that struts arm is provided with lower curved boom, the end of lower curved boom is provided with tension part, it is hook-shaped that tension part is, the end of tension part is on flat and its and is socketed with silica gel sheath, the inner side that struts arm is provided with guide ring, guide ring and strut between arm, lower curved boom, tension part one-body molded during fabrication, the extension on syringe needle through guide ring to avoid extension to tremble.
Fastening plate is arcuation, and fastening plate is used for being adjacent to the wing of nose.
Guide ring with strut arm, lower curved boom, tension part, fastening plate is plastic, lower curved boom and strut between arm and be provided with arcuation chamfering, lower curved boom and the angle strutting between arm are 75-90 degree, the angle between tension part and lower curved boom is 85-90 degree.
Guide ring aperture is slightly larger than the caliber of syringe needle, further to control the vibration scope of syringe needle upper extension tube.Guide ring plays centralizing function.
The screw of fastening plate both sides is reverse.
The extended distance that Y shape struts arm upper end is 2-3cm.
On connection-peg, be provided with locking device (valve), locking device is for sealing or open liquid supplementation pipe.
Advantage of the present utility model is: simple in structure, easy to use, control eyelid fixing firmly, facilitate fluid infusion, be specially:
Strut eyelid by support eye device, when use, slightly strut eyelid with pointing, tension part is visited between eyeball and eyelid, thumb fastens fastening plate and pulls to wing of nose direction, is adjacent to after the wing of nose to fastening plate, and canthus part struts, and now guide ring is positioned at the oblique upper of tear stains, extension or syringe needle are passed to guide ring, prevent vibration by guide ring righting, after insertion tear stains, rinse, if tear stains is unobstructed, the liquid of a unobstructed syringe is enough.If tear stains stops up, use another syringe to take out full normal saline and be inserted on connection-peg, open valve and continue to rinse.
