Abstract

A kind of eye Lacrimal passage irrigator, including probe and impregnator, including the probe being made up of needle tubing and needle handle, expansion hose that needle tubing has spiraled along its length, the forward and backward two ends of expansion hose all communicate with the inner chamber of needle tubing, and multiple micropore is distributed in expansion hose along its length；The tail end of needle tubing is connected with impregnator by needle handle.This utility model, compared with currently used lacrimal style, can not only avoid secondary inserting needle, operation time saving and energy saving, easy, alleviates the misery of patient, and improves developing result.

Description

A kind of eye Lacrimal passage irrigator

Technical field

This utility model belongs to medical instruments field, especially a kind of eye Lacrimal passage irrigator.

Background technology

Lacrimal passage blocking is commonly encountered diseases in clinical ophthalmology, generally can be overflow tear and because of dacryocystisis by the obstruction caused by inflammation, wound The inner eye corner extruding evacuation of pus caused causes.Lacrimal passage is dredged exactly for lacrimal passage blocking method most commonly.Dredge lacrimal passage at present Utensil be lacrimal probe, constitute including shank and needle handle, shank is the solid body of rod, inserts in lacrimal passage first with shank, makes Its conducting, is inserted into flush pipe, is rinsed lacrimal passage.The deficiency of this lacrimal probe is: waste time and energy, operation not side Just, misery is added to patient.

Summary of the invention

This utility model provides a kind of eye Lacrimal passage irrigator, solves to waste time and energy, inconvenient operation, increases pain to patient Bitter problem.

In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of eye Lacrimal passage irrigator, including visiting Pin and impregnator, including the probe being made up of needle tubing and needle handle, it is characterised in that: expansion of having spiraled along its length on needle tubing Flexible pipe, the forward and backward two ends of expansion hose all communicate with the inner chamber of needle tubing, are distributed multiple micro-in expansion hose along its length Hole；The tail end of needle tubing is connected with impregnator by needle handle.

Improvement further to technique scheme, described needle tubing is provided with multiple circular hole along expansion hose direction of spiraling. Advantage: this structure increases liquid outlet quantity, thus improves developing result.

Improvement further to technique scheme, described needle handle is connected with impregnator by one section of corrugated tube.Advantage: ripple The arbitrarily angled bending of stricture of vagina Guan Nengcheng, it is simple to medical personnel connect impregnator.

Restriction further to technique scheme, described impregnator is made up of cylinder, piston and piston rod, barrel front end Inner chamber be taper, the shape of piston with the inner chamber of cylinder to mating, the tail end of piston is connected with one end of piston rod.Advantage: 1. its simple in construction, production cost are low and easy to use；2. the inner chamber of barrel front end is taper, and taper has pressurization, from And improve the pressure that medicinal liquid injects.

Beneficial effect: 1. expand after injecting liquid in expansion hose, lacrimal passage can be expanded；The expansion of spiral Flexible pipe and micropore thereon can irrigation of lacrimal passages evenly；2., compared with currently used lacrimal style, secondary can not only be avoided Inserting needle, operation time saving and energy saving, easy, alleviates the misery of patient, and improves developing result.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As it is shown in figure 1, a kind of eye Lacrimal passage irrigator, including probe and impregnator, constitute including by needle tubing 1 and needle handle 2 Probe, the front end of needle tubing 1 is that blind end, its tail end are connected with needle handle 2；Spiral along its length on the surface of needle tubing 1 Expansion hose 3, the inner surface of expansion hose 3 is bonding with needle tubing 1, and the front end of expansion hose 3 extends close in needle tubing 1 front end Place, its rear end extend close at needle tubing 1 tail end, the forward and backward two ends of expansion hose 3 all by the hole on needle tubing 1 surface and The inner chamber of needle tubing 1 communicates, and multiple micropore is distributed on the surface of expansion hose 3 along its length；Along expansion hose on needle tubing 1 Direction of spiraling is provided with multiple circular hole 4；Needle handle 2 is connected with the liquid outlet of impregnator by one section of corrugated tube 5；Impregnator by cylinder 6, Piston 7 and piston rod 8 are constituted, the inner chamber of cylinder 6 front end be the inner chamber of shape and the cylinder 6 of taper, piston 7 to mating, piston 7 Tail end be connected with one end of piston rod 8；The tubulose that described expansion hose is made up of elastic film.

Using method: first insert a probe in lacrimal passage and turn on；Then by pressing piston rod, the liquid in cylinder can be made Body enters in needle lumen, and along the tube chamber entrance expansion hose of needle tubing, makes expansion hose expand, thus lacrimal passage is played expansion Effect, while expansion hose expands, micropore is progressively opened greatly, so that liquid outflow in elastic micropore, enters lacrimal passage Row large area, rinse equably；In order to increase liquid outlet quantity, the multiple circular holes on needle tubing are also used for irrigation of lacrimal passage.When pressure piston rod During adverse movement, owing to the intraluminal pressure of needle tubing reduces, so expansion hose diminishes by the contractility of self, thus realize Expansion hose is shunk, it is simple to take out probe.

Do not elaborate in this specification part, the technology being known in the art.

Claims

1. an eye Lacrimal passage irrigator, including probe and impregnator, including the probe being made up of needle tubing and needle handle, its feature exists In: expansion hose of having spiraled along its length on needle tubing, the forward and backward two ends of expansion hose all communicate with the inner chamber of needle tubing, swollen Multiple micropore is distributed along its length on swollen flexible pipe；The tail end of needle tubing is connected with impregnator by needle handle.
