Description

One kind being suitable for newborn and punctures with through periphery implantation central vein tube assembly

Technical field

The utility model relates to be implanted into central vein tube assembly through periphery, more particularly to a kind of puncture suitable for newborn is used Central vein tube assembly is implanted into through periphery.

Background technique

When newborn PICC is punctured, it is implanted into central vein tube assembly through periphery using 1.9Fr PICC conduit, it will be without The conduit of seal wire is blind to be worn, and a kind of retaining venipuncture method of central vein is particularly entered by periphery.Due to by blood of neonate Pipe lumen is relatively thin, limb circulation in side is more, angle is smaller, the development of peripheral blood vessel body surface is unclear when crossing between blood vessel, when setting pipe not Cooperate existing problems, and PICC puncture needle it is thick, it is straight, there is no toughness, nurse is uncomfortable the shadows of many factors such as to use It rings, leading to disposably to set pipe success rate is not very high, puncture needle damage, brings difficulty to pipe is set again and increases patient Expense, while stab material somewhat expensive clinically to solve this problem uses 20G venous detaining needle combined surgery knife Original puncture needle is substituted, the expense of patient has not only been reduced, but also increases puncture success rate, is reduced while having saved the time The incidence for setting phlebitis after pipe, achieves good effect.

But the 1.9Fr PICC conduit clinically used at present is different from other big-diameter pipelines, the PICC of big model Conduit is that first merging carries out end trimming in vivo again, is then fixed with fixed-wing, so the conduit use if it is big model is stayed Backed off after random can be placed in by setting needle and substituting soft needle, the trimming before not needing merging, but the conduit of big model is not suitable for newly Raw youngster is suitable for neonatal 1.9Fr PICC conduit and needs trimming in advance to measurement length, then carries out setting pipe, catheter tip It cannot be separated with buttferfly-type fixed-wing integral structure, so clinically aseptic operation knife must be used remaining needle using before setting pipe Hose is separated, so that retaining needle flexible tube is separated from conduit after conduit merging, otherwise retaining needle flexible tube will be unable to exit.But It is for clinical manipulation requirement height, degree-of-difficulty factor is big, the integration of operation of skilled operation 20G venous detaining needle and scalpel is needed, And there are security risk in operating process, careless manipulation can accidentally injure newborn, therefore a kind of convenient for the suitable of clinical promotion and application The problem of being implanted into central vein tube assembly through periphery for newborn is urgently to be resolved.

Utility model content

In view of the foregoing drawbacks, in order to solve clinically newborn 1.9Fr PICC conduit through periphery implantation central vein pipe wear It pierces, set going on smoothly for the movements such as pipe, the withdraw of the needle, improve puncture success rate, reduce newborn's pain and patient' s family at heart Burden improves clinical position efficiency, while reducing puncture cost, it is proposed that one kind is suitable for newborn's puncture and is implanted into through periphery Central vein tube assembly, specific technical solution are as follows:

A kind of puncture suitable for newborn is implanted into central vein tube assembly, including duct unit and puncture list with through periphery Member, the duct unit are made of conduit, fixed-wing, injection connector, and the conduit is flexible pipe for medical purpose structure, the catheter tip Equipped with the shearing end convenient for being trimmed to appropriate length, the conduit other end is sequentially connected fixed-wing, injection connector from left to right, The injection connector end is equipped with injection port, and the conduit, injection connector, injection port are an integral structure；The puncture unit Including puncture needle, the puncture needle is sequentially connected fixing seat from left to right, punctures seat, and the puncture needle passes through inside fixing seat simultaneously It is fixed on and punctures on seat, it is characterised in that: the puncture needle periphery is arranged with puncture tube, and the puncture tube is medical and has tough Property hose construction, the puncture pipe range 3cm, be located at puncture tube front end along longitudal section be equipped with a notch, the notch be gradually The disconnected smooth cable architecture of tearable, the incision length be the half of puncture length of tube to 2/3rds.

Further, the fixed-wing is equipped with two groups with catheter center's axial symmetry, and the sum of the height of two groups of fixed-wings is greater than The diameter of fixing seat end.

Further, the fixed-wing is circular arc sheet structure, and two groups of fixed-wings are fixed in connecting tube.

Further, the connecting tube is medical rigid plastic tube structure, and one end connecting tube, the other end is fixed on injection On connector.

Further, the fixing seat is the cumulative hollow taper pipe structure of bore from left to right.

Further, the fixing seat bottom connection injection branch pipe, described injection branch pipe one end connects extension tube, described to prolong Long tube is equipped with switch, is located at and extends pipe end connection injection interface.

Further, described puncture is equipped with for the hand-held puncture wing at the top of seat, and the puncture wing is semicircle, rectangle, ladder Shape, fan-shaped any of them structure.

Compared with prior art, the utility model has the advantage that as follows:

By the way that the notch of lacerable smooth structure that gradually breaks is arranged on puncture tube, solve clinically makes the utility model With the problem of 1.9Fr PICC conduit withdraw of the needle is difficult, puncture tube can not remove from conduit and clinically utilize 20G remaining needle The degree-of-difficulty factor for cooperating scalpel operation replacement puncture needle, substantially increases the success rate of puncture and the convenience of the withdraw of the needle, improves work Make efficiency, reduce the pain of newborn's repeated puncture and the psychological burden of relatives of newborn, alleviate the state of physician-patient relationship tense, It is worth in clinical expansion.

Meanwhile puncture tube is using the medical pipe with toughness, and a notch, the notch are equipped on longitudal section The length for puncturing the half of length of tube to one third is occupied, ensure that puncture tube can be placed in neonate in conduit It is removed from conduit afterwards, does not need to guarantee safety using aseptic operation knife, convenience easy to operate.

To sum up, the utility model structure is simple, easy to use, and compared to existing puncture tube steel needle, there are thick and stiff, punctures Success rate is low, input cost is high problem and the existing combined surgery knife clinically used carry out the operation of puncture tube removing, Operating procedure is greatly simplified, improves puncture success rate, while reducing the investment of expense cost, alleviates the negative of sufferer medical expense Load, while therapeutic effect is improved, it is worth clinically promoting.
