Description
Technical field
The application belongs to the field of medical instrument technology, and in particular to a kind of oral cavity flushing needle.
Background technique
Syringe and syringe needle are injection Medical treatment devices most commonly seen and most frequently used in existing medical diagnosis and treatment
Tool.Due to using frequently, to avoid cross-infection and easy to use, syringe and syringe needle are generally both designed as disposable product.Separately
On the one hand, different due to being applicable in medicament and the scope of application, syringe needle and syringe generally separately design, and the chamber of syringe
Body is to maintain the cavity state of unused (not holding medical fluid), and oblique wedge is generally designed in the end of syringe needle, consequently facilitating
It is pierced into skin or musculature.
But in practical application, due to the difference of disease location, general syringe and syringe needle be not completely suitable for using.For
When mouth disease diagnosis or treatment, it is limited to the narrow of oral cavity space, and to avoid accidental injury of the syringe needle to oral cavity, applying
It is not convenient enough often to use when general syringe and syringe needle, it is therefore desirable to for syringe and syringe needle used in dental care into
Row certain redesign or special transformation.
Summary of the invention

End is embedded in sealing shroud, but in general, conical end head portion is slightly above sealing shroud, consequently facilitating using), sealing shroud
Inside cavity design has fixture block, and along sealing shroud inside cavity symmetric design, seal cap edge designs have and fixture block cooperation fixture block
Convex block realizes the sealing to conical end by the cooperation of fixture block and convex block.
The oral cavity syringe, for concrete specification, syringe outer diameter Φ 8.07, syringe internal diameter Φ 6.5, push rod outer diameter Φ
The soft rubber stopper for having diameter to be slightly larger than syringe internal diameter is designed to guarantee airtightness in 6.14(but push rod end), barrel chamber capacity 1.2mL makes
Used time pre-installs 0.6mL diagnosis of brand coloring agent.
The flushing needle for cooperating the oral cavity syringe, including it is matched with the conical end of oral cavity syringe, have sky
The syringe needle fixed part and elongated syringe needle of the cone of cavity configuration；
The needle sealing, while nearly needle side wall offers injection port；In this design, due to part mouth
It is not required to inject in chamber medical diagnosis on disease or treatment, it is only necessary to spray medical fluid in privileged site, therefore, the design of this end part seal can be compared with
Avoid when misoperation existing syringe needle for stabbing caused by cavity interior well, to preferably improve safety；End simultaneously
Opening design nor affects on existing particular diagnosis or therapeutical uses；
Cavity inside for the conical end for cooperating oral cavity syringe, the cone of syringe needle fixed part is set using internal screw thread
The edge designs of meter or syringe needle fixed part have convex block, by the cooperation of convex block and fixture block consequently facilitating being fixed in sealing shroud.
In preferred design, the syringe needle of flushing needle should may be implemented one using the stainless steel alloy material with preferable toughness
The bending of degree is determined, to adapt to the use needs at cavity interior different tissues position；The stainless steel material, specifically for example
Are as follows: 304 stainless steels (or 0Cr18Ni9).
Further preferably in design, for the sterile preservation state convenient for guaranteeing flushing needle, it is configured with for flushing needle design
Openable and closable preservation set；
The preservation set is overall cylindrical, and preservation set overall length is longer than flushing needle；
Preservation set can be divided into flushing needle housing sleeve and nut cap two parts；Housing sleeve and nut cap two parts can be used plug or
It the modes such as screws and realizes folding or sealing；
Housing sleeve inside diameter (internal diameter) is suitable with flushing needle fixed part low side diameter, if while housing sleeve inner wall design have
Dry limited post；And due to flushing needle fixed part conical design, during flushing needle is placed, is fixed on housing sleeve, and
It will not be fully inserted into housing sleeve, still have part and expose to outside housing sleeve；
And nut cap inner diameter should be greater than housing sleeve outer diameter, while nut cap inner wall designs restraining position ring block, so that nut cap is being faced
It can stop after fixed part that is close or reaching flushing needle；
In preferred design, preservation set exterior side wall design has several prisms, consequently facilitating holding.
In the application, why oral cavity is designed as pre-installing certain medical fluid with syringe, mainly can avoid the meaningless etc. of patient
To, mitigate patient suffering, and the closed end of flushing needle designs and the flexible design of flushing needle, doctor, which on the one hand can be improved, to be made
With safety in the process, convenience also on the other hand is provided to adapt to different disease sites.
In general, oral cavity provided herein syringe and flushing needle are designed for oral environment, to improve
Preferable basis has been established in safety and convenience in dependent diagnostic and therapeutic process, while also being provided for Related product design
It preferably uses for reference and refers to, therefore there is preferable practical value and promote and apply meaning.
