Description
Technical field
This utility model relates to a kind of blood return indwelling needle device, particularly with the front end visible blood-flow remaining needle of threeway.
Background technology
Along with the development of nursing care delivery, remaining needle has progressively replaced traditional scalp draw point, and it can alleviate the misery that patient causes due to repeated localised puncture, protection blood vessel; Remaining needle also can reduce intravenous extravasation, the untoward reaction of having avoided venous transfusion to bring; Remaining needle can alleviate medical personnel's workload to a great extent.
Remaining needle claims again the trocar.The building block of core comprises the conduit/sleeve pipe that can be retained in endovascular softness, and stainless guiding puncture nook closing member.During use, conduit is punctured into together with nook closing member in blood vessel, after the whole intravasations of conduit, withdraw out nook closing member, thereby only soft catheter retaining is carried out in blood vessel to infusion treatment.
Current remaining needle is generally pen-shaped structure, includes needle tubing assembly and conduit tube component, and wherein needle tubing assembly includes needle tubing and needle stand, and needle tubing is hollow, and its leading section has been opened blood back groove; Conduit tube component includes conduit, catheter block, barrier assembly and the joint of extending of transparent or translucent hollow, one end of conduit is connected with catheter block, needle tubing passes catheter block inner chamber and is plugged in catheter lumen, barrier assembly is a kind of batching pig with certain length, and it is arranged on catheter block inner chamber in tight fit mode; Under the effect of batching pig, catheter block inner chamber forms a blood back cavity before batching pig, and this blood back cavity is communicated with joint of extending.Therefore, blood back is all at syringe rear end when puncture vein blood vessel for remaining needle, and the visible blood-flow time is longer.
Three-way device is the device that connects remaining needle and transfusion device, after indwelling connects threeway, just can connect two transfusion devices, with two transfusion devices, infuses together, therefore have medication facilitate, without setting up the advantages such as many venous channels, minimizing patient misery.But in venous detaining needle and three-way device convergence process, there is the problems such as fixing shakiness, inconvenient operation, leakage.
Utility model content
This utility model is in order to address the above problem, and this utility model provides a kind of function combinations by remaining needle and three way cock to be integral, and has the solution of front end blood back function.
To achieve these goals, this utility model provides following technical scheme:
A front end visible blood-flow remaining needle with threeway, comprises needle tubing 1, thimble assembly 2, threeway parts 3, connector assembly 4, needle stand assembly 5, cap 6;
Wherein, on needle tubing 1, be provided with blood back hole 11, and the blood back groove on its position and triple-valve body 32 matches;
Thimble assembly 2 is connected to form by sleeve pipe 21 and casing seat 22, and sleeve pipe 21 front ends are provided with most advanced and sophisticated molding structure, and end is provided with horn mouth and casing seat 22 is sealedly connected and fixed.
Three-way component 3 is comprised of spool 31 and triple-valve body 32, and valve body front end is provided with blood back groove 33;
Connector assembly 4 is comprised of connector 41, plug 42, capping 43;
Needle stand assembly 5 is comprised of needle stand 51, Coupling 52, safety device 53.
The connected mode of this structure is: the remote outlet of thimble assembly 2 and three-way component 3 is connected and fixed, and connected mode can be the forms such as cementing, laser weld, ultrasonic bonding;
Connector assembly 4 and three-way component 3 near-end outlets adopt female Luer to screw fixing;
Needle tubing 1 is fixedly connected with and is integral with needle stand assembly 5 ends, by the local interface insertion combination of thimble assembly 2, three-way component 3 and connector 4 molectrons; The side direction joint rotating connection cap 6 of three-way component 3.
As preferably, this three-port structure is illustrated as and is arranged symmetrically with.
The beneficial effects of the utility model are, remaining needle and three way cock's function combinations is integral, and have overcome connecting tee joint complicated operation in prior art and have been inconvenient to obtain problem, have front end blood back function simultaneously, reduce operating room operating procedure and time.
