Abstract
The invention discloses a long-handle two-way folding pipe-free rolling type backflow preventing venous indwelling needle. The venous indwelling needle comprises a needle protecting cap, a needle core, a cannula, a trapezoidal long needle handle, a transparent two-way part, a white isolation plug, a short-flat needle wing, a rolling liquid stopper, an extension tube, a hanging belt, a dual-purpose needle bolt cap and a bayonet, wherein the trapezoidal long needle handle is fixed at a protrusion on the right side of the cannula, and can be gripped transversely at the middle parts of finger pulps of a thumb and an index finger without overturning; the top end of the short-flat needle wing is straight, and the outer side of the short-flat needle wing is arc-shaped, and the needle core can be easily withdrawn by a single finger; backflow can be prevented by closing a pulley on the rolling liquid stopper, and the negative pressure is generated in the extension tube to easily result in blood return by opening the pulley on the rolling liquid stopper; a pintle at the tail end of the extension tube of the transparent two-way part is not bifurcated; the dual-purpose needle bolt cap is fixed on the hanging belt, and threads are arranged in the cap, and the bayonet is arranged at the cap top to prevent an intravenous needle from shedding and rotating. Compared with the prior art, the long-handle two-way folding pipe-free rolling type backflow preventing venous indwelling needle disclosed by the invention has simple structure, easy blood return while puncturing, no inversion of the needle handle and no contamination on the cap top.
Description
Technical field
The invention belongs to venous detaining needle field, relate to a kind of disposable long handle two-way and hinder, without broken pipe roller, the venous detaining needle that backflows, and
It is linked with at extension tube end and has a dual-purpose pintle cap.Especially fixing trapezoidal length is held needle handle and is easily punctured horizontal gripping, nonreversible, holds level with both hands before the pin wing
The straight easily withdraw of the needle, two-way is light portable.
Background technology
Medical single use venous detaining needle is one of the most conventional medical apparatus, and its essential structure is by protecting needle cap, sleeve pipe, hand folder, pin
Core, the pin wing, transparent threeway, white batching pig, extension tube, white end cap, calparine cap, when intravenous injection, having a kind of situation is to work as quilt
Puncture person's blood vessel compared with deeply, compared with thin or time table is shallow, when inserting needle is the biggest or needle angle is less, sleeve pipe is the most curved, and the pin wing is from point of puncture in addition
Far, suspend fixing, profile camber, can only take the photograph handle during puncture, and the suspension pin wing easily rotates, and needle angle is difficult to adjust, thus to Deep venou and
The shallow tiny vein of table be difficult in thorn or easily penetrate through, this reduces success rate and the range of venous detaining needle, another kind of situation is pin
Contour of flange is curved puncture successfully after singly refer to that pusher is difficult to operation, pushing sleeve pipe and pull out nook closing member speed and differ forward, cause broken pipe, indwelling failure；By
In heparin, liver being had damage, physiological saline commonly used by tube sealing clinically, therefore calparine cap is useless, so can reduce by a passage, again can be because puncturing after
Multi-pipeline and the hidden danger that causes；And hand folder hand or hands thrust is excessive, hand folder pushes away folder frangibility when transparent three-way connection and extends
Pipe, causes indwelling failure；White end cap removes after connecting transfusion device to be placed nowhere, easily loses, and white end crown end can not be with being needled into, it is necessary to
Go cap can connect transfusion device, do not remove white end cap, and scalp intravenous needle is directly thrust calparine cap, need with adhesive plaster scalp is quiet after thrusting
The needle handle of holding of arteries and veins pin is fixed on slip-off preventing on calparine cap, and otherwise pin is drawn out easily and causes transfusion to interrupt.
Summary of the invention
It is an object of the invention to provide a kind of fixing trapezoidal length to hold needle handle, transparent two-way, the short formula pin wing, rolling liquid-stopping device, can thrust from carrying two
Use pintle cap.Fixing trapezoidal length holds needle handle: because horizontal needle handle length of holding increases therefore without upset, the skin having stopped to cause because needle handle overturns stab or
Blood vessel pierces through, and ensure that puncturing successfully rear sleeve, without exiting phenomenon, improves indwelling success rate simultaneously；Short formula pin wing top is straight, at withdraw of the needle core
Time Dan Zhike move back convenient and strength-saving；Transparent two-way simplifies indwelling needle device, it is to avoid multichannel causes and infects, and makes the easier use of remaining needle；
Rolling liquid-stopping device one hand operable, double wall power is big, without backflowing after tube sealing, has stopped the Blood occlusion that remaining needle is backflowed, simultaneously to thinner blood
Close when pipe punctures, open the extension tube interior generation easy viewing blood return effect of negative pressure after rolling liquid-stopping device, it is ensured that puncture and indwelling success；Can thrust
Dual-purpose pintle cap, can not go cap rate controlling to infuse, and protrudes from and have a longitudinal bayonet socket on the right side wall of crown, can be by the scalp intravenous needle on transfusion device
It is elastic thrust plastics that handle embeds bayonet socket, the rotation in case scalp intravenous needle comes off, and crown, and crown caves in cap, and operator's hand is difficult to
Polluting crown, thus prevent cross-infection, as needed quick infusion, go cap to connect transfusion device, cap is because being difficult to loss on being linked with.The present invention is one
Kind of applied widely, multiple functional, puncture success rate and the high venous detaining needle of indwelling success rate, its simple light portable anti-infection.
The present invention uses following technical proposals:
Long handle two-way is backflowed venous detaining needle without the resistance of broken pipe roller, and it includes protecting needle cap, sleeve pipe, nook closing member, trapezoidal length hold needle handle, transparent two-way, white
Look batching pig, the short flat pin wing, roll liquid-stopping device, be linked with, dual-purpose pintle cap.Described remaining needle is fixed trapezoidal length and is held needle handle and extension tube
On have one movably to roll liquid-stopping device, and on extension tube is linked with, have a dual-purpose pintle cap.
Described trapezoidal length is held the upper end of needle handle and is fixed at sleeve pipe right side wall knuckle, and trapezoidal length holds on needle handle drift angle away from sleeve pipe right side wall knuckle at the end
0.4-0.5cm, trapezoidal high 1.4-1.7cm.
The described short flat pin wing, at the end of nook closing member, the top of its pin wing is straight, and outside is curved, arc length 1.5cm.
Described transparent two-way, communicates with extension tube, without bifurcated on the pintle of the extension tube end of its transparent two-way.
Described rolling liquid-stopping device is placed in extension tube, rolls liquid-stopping device and conventional adjuster difference is, roll liquid-stopping device groove lower housings
Four angles curved, volume is 1/3rd of conventional adjuster.
Described dual-purpose pintle cap is fixed on extension tube pintle end and is linked with, cap inwall have screw thread, crown be elasticity can the plastics of acupuncture, crown
Depression, in cap, protrudes from the longitudinal bayonet socket having one and horizontal line on crown right side wall.
The present invention is the remaining needle of a kind of portable portable multifunctional, and it is applied widely, punctures indwelling success rate high, and it can reduce remaining needle
Use cost, easily operates anti-set pipe choking, has stopped indwelling failure, thus it is painful to alleviate patient, won valuable time for treatment.
