Summary of the invention
The present invention provides a kind of cone joint oral cavity card and occupies bottle anesthetic driving means, to solve to mention in above-mentioned background technique
The problem of simple structure out.
Technical problem solved by the invention is realized using following technical scheme:
A kind of cone joint oral cavity card occupies bottle anesthetic driving means, including cylindrantherae, push rod, end cap, and the end cap is fixed to be connected
It connects at the top of cylindrantherae, the bottom of the push rod is located in cylindrantherae;
The cylindrantherae is cylindrical shape, and bottom surface is equipped with bottle plug puncture unit in the cylindrantherae, is equipped with runner in the bottle plug puncture unit,
The cylindrantherae bottom end is fixedly connected with outer circle taper joint, the outer circle taper joint smooth outer surface, table in the outer circle taper joint
Face is equipped with internal screw thread, is equipped with drain column inside the outer circle taper joint, the drain top end is fixed on the bottom end of cylindrantherae, described
The bottom end of cylindrantherae is equipped with through-hole, is equipped with channel in the drain column, the one end of the channel communicates with the outside world, and the other end passes through through-hole
It is communicated with runner, the side side of the cylindrantherae is equipped with first window, and the other side is equipped with the second window;
The push rod side is equipped with annular spacing groove, is equipped with rubber seal, the push rod bottom in the annular spacing groove
End is fixedly connected with connecting column, and the connecting column bottom end is fixedly connected with sharp portion, and the sharp portion bottom end is inverted cone-shaped, institute
It states and is fixedly connected with push ring at the top of push rod;
The side of the end cap is equipped with the first extension arm, and the other side is equipped with the second extension arm, and the first extension arm bottom surface is set
Have the first groove, the second extension arm bottom surface is equipped with the second groove, first groove, the second groove section be arc
Shape.
The cylindrantherae, push rod, end cap are molded by polymethacrylates or acrylonitrile resin.
The size of the outer circle taper joint is 6:100 taper.
The invention has the benefit that
1 push club head is designed as " sharp portion ", convenient for alignment cassette narcotic bottle tail portion cross foresight and is inserted into tail portion rubber plug,
The design of " sharp portion " is to inject Shi doctor in clinical anesthetic to need rubber stopper of pulling back, and judges whether there is " blood back ".
Outer circle taper joint is designed as on the outside of 2 cylindrantherae moulding heads, joint dimension is 6:100 taper, this design meets GB/
The regulation of T1962.1-2015.
Rubber seal is installed at 3 push club head annular spacing grooves, plays the role of sealing, not leakiness when clinical manipulation
Liquid.
4 push rod tail portions are designed using lantern ring type, and when operation gos deep into thumb in lantern ring, more stable convenient for injecting.
Index finger and middle finger hook the first groove and the second groove of end cap when 5 injection, meet body mechanics' design.
6 this products are disposable medical instruments, need to destroy by regulation after, and disposable feature is safer, phase
Compare the reuse of Luer's syringe, it is avoided pulls out needle, needle exchange operation repeatedly, avoids utensil sterilizing operation repeatedly.
There are two " windows " to design for 7 cylindrantherae moulding heads tool, it is therefore an objective to which narcotic bottle exits after being easy to use.
If the production of 8 metal mold oral cavity clip connection type syringes inaccurately or because of service life too long, all will by Reusability
Cause syringe push handle precision insufficient, when causing to push anaesthetic, the pumping that can not fall syringe push handle is inserted with tip
In the cross foresight for entering cassette reagent bottle centre, in this way, can to push end cork due to the inequality for pushing strength
Inclination movement, thus generation the case where cause leakage.
9 this product cartridge designs are cassette [cartridge] dosage form, are the dosage forms generally used in the world, are effectively improved
The shortcomings that using ampoule [Amp] dosage form, the medicine bottle of ampoule [Amp] dosage form first must cut bottleneck in clinical use
It opens, then medical fluid is drawn into injection device, this process directly exposes drug in air, increases the probability of pollution, together
When cutting bottleneck when be easy to powder particle is caused to fall to be caused in medical fluid to patient's potential harm.
