Description

Integral type gas-liquid exchanges syringe needle

Technical field

The utility model relates to the relevant processing and manufacturing fields of Medical Devices, and in particular to be integral type gas-liquid hand over Needle exchange head.

Background technology

In the therapeutic process of ophthalmology recurrent vitreous hemorrhage, the vitrectomy of 3 channels is generally required, is needed Sterile medium is perfused first（Balance salt, inert gas or air）To eyeball, drainage device is then inserted by vitreum In hydrops drain come, the distress level of patient is larger in the process, and the program in surgical procedure is complex, and postoperative It also needs to carry out suture processing.

Invention content

The utility model aim is to provide integral type gas-liquid and exchanges syringe needle, it can be efficiently solved in the presence of background technology The problem of.

In the presence of solving the problems, such as background technology, it includes needle tubing 1, and the bottom of the needle tubing 1 is provided with positioning pipe 2, the inside of the needle tubing 1 is axially provided with a partition board 3, which extends in positioning pipe 2, and positioning pipe 2 is separated out can The flushing chamber a docked with flush pipe 4 the and back cavity b docked with return duct 5, the end of the flush pipe 4 be equipped with for The plug 6 of syringe docking, the end of the return duct 5 is equipped with vacuum liquid-collection bag 8, tune is equipped on the return duct 5 Save valve 9.

As a result of above technical scheme, the utility model has the advantages that：Simple in structure, patient can sit Under the state of position, from the eyeball lower section flat portion's inserting needle of ciliary body, hematocele is drained, while filtrated air or balanced salt solution can also be injected It is rinsed, since one-time puncture can be completed all operations, notch after minor operation compared with, without suture, greatly reducing The pain of patient.

Description of the drawings

It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, can also be obtained according to these attached drawings other attached drawings.

Fig. 1 is the structure diagram of the utility model.

Specific embodiment

In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, under The attached drawing that face will be combined in the utility model embodiment, carries out the technical scheme in the embodiment of the utility model clear, complete Ground describes.

Referring to Fig. 1, present embodiment is achieved using following technical scheme, it includes needle tubing 1, the needle tubing 1 Bottom be provided with positioning pipe 2, the inside of the needle tubing 1 is axially provided with a partition board 3, which extends to positioning pipe 2 It is interior, positioning pipe 2 is separated out the flushing chamber a that can be docked with flush pipe 4 and the back cavity b docked with return duct 5, the flush pipe 4 end is equipped with the plug 6 for being docked with syringe, and the end of the return duct 5 is equipped with vacuum liquid-collection bag 8, described Return duct 5 on regulating valve 9 is installed.

In use, conduction anesthesia after ball is carried out to patient first, and routine disinfection, eye circumference patch sterile film.Doctor sterilizes, Wear sterile gloves.Syringe is docked with plug 6, and at least one in the built-in balance salt of syringe, air or inert gas Kind, the pressure of regulating valve 9 is adjusted to about 10-20mmHg, i.e. pressure is more than this numerical value（10-20mmHg）When, eye fluids can With outflow.The flat portion's inserting needle of ciliary body below patient's eyeball is slowly injected with syringe in balance salt, air or inert gas At least one, return duct 5 draws hematophthalmia, until intraocular is limpid or gassy, operation terminate.

High myopia is used for when synchysis patient retinal disease is treated using the present apparatus, and use aspect is similar.

For the drainage of other cavities or tumour, service condition is similar, and the medicines such as antibiotic can be also added in flushing liquid Object.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that, It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc. With replacement；And these modifications or replacement, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution The spirit and scope of scheme.
