One end of the quantification storage bag is connected with the injection syringe needle, the other end of the quantification storage bag is connected with the hose, and the hose is communicated to the needle tube. According to the multifunctional eye microsyringe, the risk for perforating intraocular tissues due to incongruity of operation of two persons can be removed, the accuracy of the injection amount is guaranteed, especially waste of precious drugs is reduced, the activity of the cells is guaranteed, the effectiveness and the uniformity of the drugs or cell factors or therapeutic cells are ensured, the therapeutic effect is improved, and the hidden danger of contamination and infection is lowered. The multifunctional eye microsyringe is low in manufacturing cost, disposable, and capable of removing the disinfecting procedure and effectively avoiding the danger of iatrogenic cross infection and the danger of contamination between injection drugs and injection cells.
Description
Technical field
This utility model belongs to area of medical devices, is specifically related to a kind of Multifunctional eye microsyringe.
Background technology
At present, all adopt pen type micro glass syringe to carry out the injection of intraocular drug, cytokine or therapeutic cells both at home and abroad.Because microsyringe is grown (the long 30mm of common metal syringe needle, glass needle pipe range 85mm, the long 128mm of whole syringe), operator inserts injection needle at the ophthalmic positions such as anterior chamber, vitreous chamber or subretinal space, hand syringes, need assistant's pressing handle injected injectate to the ophthalmic chamber, the assistant is difficult to and the operator cooperation, micro-have careless syringe needle very easily to wear out the adjacent tissue in damage injection site, as iris, crystalline lens or retina etc., cause and inject unsuccessfully, a series of complication such as intraocular hemorrhage.Glass microsyringe commonly used, the syringe needle interior diameter is 0.0826～0.184mm, at present adopt rinse after the disinfection way of medicining liquid dipping, because the syringe needle internal diameter is very thin, rinse or soak insufficiently, all can cause the pollution of medical cross infection or injection.
Summary of the invention
Solve existing problem in above-mentioned prior art for better, this utility model provides that a kind of operation is simple, and can make the safer Multifunctional eye microsyringe of intraocular injection.
In order to realize the foregoing invention purpose, this utility model by the following technical solutions:
Design a kind of Multifunctional eye microsyringe, comprise injection needle and needle tubing, flexible pipe, for the quantitative storage capsule of storage of pharmaceutical or cell, described quantitative storage capsule one end is connected in the tail end of described injection needle, the other end of described quantitative storage capsule is connected in an end of described flexible pipe, and the other end of this flexible pipe connects described needle tubing.
Be provided with filter cotton at the described hose connection end to quantitatively storing capsule.
Described filter cotton is the organic filter cotton of micropore, and the length of this filter cotton in flexible pipe is 5～8mm, and its micro-pore diameter is 0.22～0.45um.
Described injection needle is provided with needle handle.
Described needle handle is wrapped in the tail end of described injection needle.
The needle point of described injection needle is the needle point of surface through the silicone grease lubricated.
The size of described injection needle is 28～34G, and the length of injection needle is 8～15mm, and overall diameter is 0.184～0.36mm, and interior diameter is 0.0826～0.184mm.The thickness of injection needle is the most important key element of intraocular injection, the thickness of injection needle is meaned by English alphabet G, the numerical value of G front is larger, represent that injection needle is thinner, should, according to the position of intraocular injection, the characteristic of injectable drug and the size of injection for curing sexual cell diameter, select suitable injection needle specification.
Described flexible pipe is made by medical silica-gel.
Described needle tubing is to be made by medical plastic.
The utlity model has actively useful technique effect:
1. the Multifunctional eye in this utility model is hose connection between injection needle and needle tubing with one section of microsyringe employing, makes between injection needle and needle tubing to possess certain buffer capacity, has overcome two people and has operated the inharmonious risk of wearing out eye inner tissue of bringing;
2. the Multifunctional eye in this utility model has been installed a medicine or cell and has quantitatively been stored capsule between flexible pipe and syringe needle with microsyringe, overcome existing microsyringe nook closing member thinner, error easily appears in the suction drug dose, while especially injecting organic solvent, the extremely inaccurate defect of dosage of microsyringe suction, guarantee the degree of accuracy of injection volume, especially reduced the waste of costly medicine; Quantitatively store the installation of capsule, can effectively alleviate the pressure in needle tubing, avoided because the intraluminal pressure of fine needle is larger, easily cause the damage problem of cell in the process of suction, guarantee the activity of cell, guarantee the effectiveness of medicine, cytokine or therapeutic cells, guaranteed the effect for the treatment of; In addition, because injected therapeutic cells is to be suspended in cell culture fluid, after static a few minutes cell often be deposited on cell culture fluid below, so the cell concentration of injecting on demand after cell mixes is divided in each, quantitatively store in capsule, guaranteed the cell number of injection, the cell be divided in quantitative storage capsule is convenient to storage, is carried and transport, guaranteed the activity of cell or cytokine, reduced the blindness that in the art, by volume cell concentration is injected in interim suction, also reduced the opportunities for contamination operated in operation; Use and quantitatively store the cell that capsule is filled to some in advance, the cell number that the animal of the patient of the every a collection for the treatment of of assurance or experiment receives in treatment is consistent, guarantee the homogeneity of medicine, cytokine or therapeutic cells, reduced the error for the treatment of or experiment.
3. the Multifunctional eye microsyringe in this utility model, be built-in with filter cotton at the flexible pipe that connects storage capsule one end, and the harmful gas in filtered air or small items, reduced the hidden danger of polluting and infecting.
4. Multifunctional eye microsyringe of the present utility model, operation is simple, make that intraocular injection is safer, more convenient, the activity of guaranteeing cytokine or treatment cell, avoided operator and assistant to operate the risk that the inharmonious eye inner tissue that brings is damaged, Multifunctional eye of the present utility model microsyringe low cost of manufacture, can disposablely use, remove disinfectant program, avoid the danger of polluting between medical cross infection and injectable drug, be applicable to all investigative technique librarian uses in all Clinical Ophthalmology doctor, nurse and this area.
