Abstract

The utility model relates to a belongs to disposable lacrimal passage irrigator belonging to a clinical therapeutic device for the ophthalmology. The utility model comprises an irrigating needle, a hand holding handle, an irrigating pipe and a one-way valve, wherein, the irrigating needle which is made of plastic is designed to form a hollow conical shape; theirrigating needle is provided with the hand holding handle; the tail end of the irrigating pipe is a joint for injection connection, and the joint has an inserting structure matched with the head of an injection syringe; the one-way valve is arranged between the irrigating pipe and a joint on the tail end. The utility model can avoid the defects existing in the existing lacrimal passage irrigating structure, and the utility model has the characteristics of simple operation and zero cross infection or pollution.

Description

Disposable irrigation of lacrimal passage device

This utility model belongs to the clinical ophthalmology therapeutic device, mainly proposes a kind of disposable irrigation of lacrimal passage device, is used for simple property obstructed lacrimal passage and chronic dacryocystitis patient's irrigation of lacrimal passage and the preceding flushing of inner eye operation lacrimal passage.

Simple property obstructed lacrimal passage or chronic dacryocystitis patient, frequent epiphora or have purulent secretion to overflow to cause the patient suffering, understand position and the degree that lacrimal passage stops up with the method for irrigation of lacrimal passage, the while again can be in lacrimal passage perfusion solution reach the purpose of treatment.What washed the lacrimal passage employing is the metal syringe needle of self-control blunt point in the past, directly be connected in before the syringe in the insertion lacrimal passage repeatedly and wash, it exists, and following some is not enough: 1, the internal diameter of this its diameter of metal Syringe needle Irrigator the same thickness and lacrimal point, tear stains from the front end to the rear end is not consistent, flushing liquor easily backflows out from lacrimal point during flushing, can not make and produce certain pressure in the lacrimal passage, flushing liquor can not flow into nasopharynx part by lacrimal passage smoothly, thereby the error diagnosis that causes lacrimal passage to stop up.2, the metal Syringe needle Irrigator is sharper, inserts the damage that lacrimal passage easily causes the lacrimal passage mucosa repeatedly, causes pain, and particularly children's fears to mismatch and causes flushing difficulty, easily stabs eyeball.The operator is not easy to fix with hands clamping Syringe needle Irrigator when 2, using.4, the metal Syringe needle Irrigator uses the back with after the 75% alcohol-pickled sterilization, uses repeatedly, easily causes cross infection.

The purpose of this utility model promptly is to propose a kind of disposable irrigation of lacrimal passage device, thereby solves the existing problem of existing flushing lacrimal passage structure.

This utility model is finished the technical scheme that its invention task taked: it comprises flushing needle, hand holding handle, syringe pipe and check valve; The flushing needle that adopts plastic material to make is designed to the taper shape of hollow, the tube chamber physiological characteristics that meets lacrimal point, tear stains, the flushing needle rear end is provided with hand holding handle and the two is designed to integrative-structure, the terminal socket connection of syringe pipe and flushing needle, one check valve is set between syringe pipe and the end connector, can prevent that when changing flushing liquor the flushing liquor refluence pollutes in the tube chamber, the end connector of syringe pipe is for kissing the structure of joining grafting with syringe nozzle.

The disposable irrigation of lacrimal passage device of this utility model can be avoided the existing existing defective of irrigation of lacrimal passage structure, and has easy and simple to handle, no cross infection and pollution characteristics.

Embodiment:

Accompanying drawing 1 is this utility model structural representation.

The embodiment that provides with reference to accompanying drawing is further specified its structure:

As shown in Figure 1, this irrigator comprises flushing needle 1, hand holding handle 2, syringe pipe 3 and check valve 4; Flushing needle 1 and check valve 4 adopt plastic material to make, flushing needle 1 is designed to the taper shape of hollow, meet lacrimal point, the tube chamber dissect physiology structure of tear stains, when the flushing lacrimal passage, flushing liquor is difficult for excessive, can make and produce elevated pressures in the lacrimal passage, flushing liquor is easy to arrive nasopharynx part by lacrimal passage, effectively reduced the false judgment that lacrimal passage stops up, the flushing needle rear end is provided with hand holding handle 4 and the two is designed to integrative-structure, can hand easily flushing needle is accurately inserted lacrimal passage, syringe pipe 3 and flushing needle 1 terminal socket connection are provided with check valve 4 between the joint 5 of syringe pipe 3 and tail end, be used to prevent that flushing liquor from falling to overflow, the joint 5 of syringe pipe tail end in order to be connected with syringe, injects lacrimal passage with flushing liquor by irrigator by syringe for kissing the connected structure of joining with syringe nozzle.

Claims

1, a kind of disposable irrigation of lacrimal passage device is characterized in that comprising flushing needle (1), hand holding handle (2), syringe pipe (3) and check valve (4); The flushing needle that plastics are made (1) is designed to the taper shape of hollow, flushing needle (1) rear end is provided with hand holding handle (2) and the two is designed to integrative-structure, syringe pipe (3) and the terminal socket connection of flushing needle (1), between syringe pipe (3) and the end connector (5) check valve (4) is set, the end connector of syringe pipe (3) is for kissing the structure of joining grafting with syringe nozzle.
