Description
Technical field
This utility model relates to a kind of adnexa of hypodermic syringe, more particularly, relates to a kind of segregation apparatus of syringe needle.
Background technology
At present, plastic injector for temporary use has been substituted and has used glass syringe for many years in medical institutions, has avoided the generation of medical cross infection in the hospital effectively, has been subjected to extensive patients and medical personnel's welcome.Conventional injector generally is to be with a needle guard outside the syringe needle of syringe, during use needle guard is taken off, after injection finishes, normally with the hands needle guard is put once more syringe needle or with the hands the syringe needle of syringe is separated with needle tubing and store respectively, in case being caused by exhausted needle sting, other people infect or disease, then used syringe is concentrated destruction, the cross infection that causes in case used disposable syringe is repeated to use.But, the medical personnel is at needle guard or with the hands with used syringe needle isolating time the on used pinhead sleeve with the hands, be easy to meet accident and stab, and then may infect or disease owing to stabbing to cause, and present infectious disease is more, for example acquired immune deficiency syndrome (AIDS), hepatitis B, syphilis or the like, its consequence is serious after infecting above-mentioned infectious disease, owing to there is this danger, " Centre for Disease Control " suggestion is needle guard or with the hands used syringe needle is separated on used pinhead sleeve with the hands not.
In order to protect the medical personnel; reduce unnecessary malpractice; for example " being used for safety takes off; store and dispose the case of entry needle " of Chinese patent CN1013188B bulletin appearred; this case is provided with a binding clasp that is suitable for receiving the swing handle part of the entry needle that will take off from syringe; compression opening and be used for when syringe takes off entry needle, clamping the swing handle of entry needle when binding clasp is suitable for being pushed by the operator who arrests this device; though this case can take off the syringe needle of syringe safely; do not need with the hands used syringe needle to be separated; avoided the accidental needle sticks that was used and infected or morbific danger; but its complex structure, it is not very convenient using.
Summary of the invention
This utility model purpose be to overcome above-mentioned shortcoming and provide a kind of not only can safe separating syringe needle and device simple in structure, easy to use, the technical scheme of employing is as follows:
A kind of segregation apparatus of syringe needle, it is characterized in that: this segregation apparatus comprises an operation panel, operation panel is provided with one and separates syringe needle clamping slot that syringe needle uses and the syringe needle mouth that drops, this syringe needle clamping slot comprises a rectangular channel and a dovetail groove, the small end of dovetail groove is connected with rectangular channel, and its big end and syringe needle drop and mouthful be connected.This rectangular channel can be used to separate conventional needles, and this dovetail groove can be used to separate unconventional syringe needle.
The swing handle of conventional injector syringe needle generally is taper, swing handle is provided with circular protrusions or rib to make things convenient for being connected or separating of syringe needle and needle tubing, what the bar number of circular protrusions or rib was common is two or four, the bar number of circular protrusions or rib is the more rare of other even number bars, and the bar number of circular protrusions or rib is that the odd number bar is extremely rare.The width of described rectangular channel is greater than the minimum range of two adjacent circular protrusions or rib on the taper swing handle of syringe needle, and this width should be less than or equal to the ultimate range of two relative circular protrusions on the taper swing handle of syringe needle or rib simultaneously.When the width of rectangular channel was less than or equal to the minimum range of two adjacent circular protrusions on the taper swing handle of syringe needle or rib, the taper swing handle of syringe needle can't insert rectangular channel; When the width of rectangular channel greater than the taper swing handle of syringe needle on during the ultimate range of two relative circular protrusions or rib, the taper swing handle of syringe needle can't tighten with rectangular channel.
The width of described dovetail groove small end equates that with the width of rectangular channel this dovetail groove is the isosceles trapezoid groove preferably.
The size that described syringe needle drops mouthful should be greater than the size of syringe needle, and its shape can be designed to circular trough, rectangular channel or elliptical slot etc. as required.
Insertion for the ease of syringe needle can easily vertically be inserted the syringe needle clamping slot with the taper swing handle that makes syringe needle, and the longitudinal section of described syringe needle clamping slot is trapezoidal or the class trapezoidal shape, and such trapezoidal shape is a rectangle that has chamfering.
Described operation panel can be designed to the container end of a closed container device, and this case comprises one one end sealing, other end opening, is used to store the storage container parts of used syringe needle, with a container end that is contained in this storage container component openings end, the storage container parts can be designed to shapes such as cylinder, spheroid or cube as required, in the storage container parts disinfectant solution can be housed, be convenient to used syringe needle is carried out concomitant disinfection.
The segregation apparatus of syringe needle of the present utility model, simple in structure, be applicable to the separation of all size syringe needle; Safe and convenient to use, user only needs one hand to hold syringe needle tube, used syringe needle is inserted the syringe needle clamping slot, being rotated counterclockwise needle tubing again can separate syringe needle with needle tubing, avoided the medical personnel with the hands on used pinhead sleeve needle guard or when with the hands used syringe needle being separated accident infected or morbific danger by needle sting; This separation device can be designed to the container end of closed container device, leave in after syringe needle is separated in the storage container parts, avoided the accidental needle sticks that other people were used and infected or morbific danger, in these storage container parts disinfectant solution can be housed, be convenient to used syringe needle is carried out concomitant disinfection; In addition, this segregation apparatus cost is low, helps promoting in each department.
