Abstract
The invention discloses a negative pressure puncture needle which is convenient for operation, safe and reliable. The negative pressure puncture needle is made by adding a spring and a simple switch on the basis of a common injector; and when the negative pressure puncture needle is punctured into tissues, the switch is pressed down and then negative pressure is automatically formed, so that a function of withdrawing while puncturing is provided. The negative pressure puncture needle causes small wounds to patients and causes fewer dangers.
Description
Affiliated technical field
The present invention is that a kind of controllable negative pressure puncture needle, especially one hand of making things convenient for can be accomplished puncture, and negative pressure continues to exist, and is little to patient trauma.
Background technology
At present, there are a lot of diseases need do examination by centesis and treatment, like cyst puncture before pleural space puncture, lumbar puncture, the kneecap etc. at medical domain.Its piercing method is to use ordinary syringe, on one side two handss puncture, Yi Bian pumpback; Its operating process is loaded down with trivial details, the syringe needle swing, and increase patient's misery, negative pressure can not continue to form, and mistake is worn easily.
Summary of the invention
In order to overcome the deficiency that existing operational approach is loaded down with trivial details and the equipment negative pressure can not continue to form, the present invention provides a kind of negative-pressure puncture needle, and this pin low price is easy to use, and one hand can be accomplished the negative pressure puncture, also reduces the infringement to patient.
The specific embodiment
The ordinary syringe of common different model is done following change, begin to make a card at the position of syringe total length 1/4th from the tail end of syringe, prevent that the piston in the syringe from deviating from, this card is also as the force part of spring simultaneously; Doing diameter at the syringe tail end-side near Ka5mm-1cmChu is that the aperture of 4-6mm is a switch hole; Under the situation that piston resets fully, to do a resilient convexity be interior switch at the position of corresponding switch hole on axle is done, and can be stuck on this aperture just; Axle between card in the syringe and the dried handle of axle is done spring that dynamics is suitable of cover; Do the thing of a similar pen card in syringe tail end outside, end has its length of a convexity (for outer switch) to be slightly larger than the thickness of needle cylinder wall, can insert aperture and corresponding with it.During operation, when syringe needle penetrates when organizing, press outer switch, the convexity that just can do axle pushes back syringe inside, axle do will be under the effect of spring the pull-up piston, negative pressure can form.
The invention has the beneficial effects as follows apparatus low price, the easy to operate and lasting existence of negative pressure.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is an overall diagram of the present invention
Fig. 2 is piston and the dried side bitmap of axle
Fig. 3 is a sleeve side bitmap
Piercing needle among the figure (1) axle is done (2) spring (3) piston (4) the card outer switch of (5) interior switch (6) (7) switch hole (8) syringe (9) axle dried handle (10)
The size of the syringe among Fig. 1 can be made into different model as required.Spring is different according to required vacuum magnitude, selects the spring of different dynamics.
Interior switch among Fig. 2 is outstanding from the dried side of axle, and becomes 45 with it; Its terminal outside is parallel with the dried longitudinal axis of axle, and it is wide identical with thickness sleeve wall in dried pommel side of axle and the dried transverse axis of axle for it, becomes 45 by piston side and spool dried.
Claims (4)
1. a negative-pressure puncture needle is that the ordinary syringe transformation of the way forms, and it is characterized in that doing a P cock at the sidewall of common syringe, and the axle between card in the syringe and the dried handle of axle is done spring that dynamics is suitable of cover.
2. negative-pressure puncture needle according to claim 1; The ordinary syringe of its characteristic different model begins to make a card for the position of its total length 1/4th from its syringe tail end; Prevent that the piston in the needle tubing from deviating from, this card is also as the force part of spring simultaneously.
3. negative-pressure puncture needle according to claim 1, its characteristic is done an aperture at the syringe tail end-side near the position of card, does on the respective apertures position at the axle in the needle tubing and does a resilient convexity, can be stuck in just on this aperture.
4. negative-pressure puncture needle according to claim 1, its characteristic are done the thing of a similar pen card in syringe tail end outside, end has a convexity can insert aperture, and the elastic bumps that can do axle pushes back in the sleeve.
