Description

Y shape bend pipe connector

Technical field

The utility model relates to a kind of Medical Devices more particularly to a kind of Y shape bend pipe connectors, are mainly used for Deep venou and wear Thorn sets the puncture and intubation of pipe, especially subclavian vein.

Background technique

Subclavian vein catheterization technology is widely used in clinical every field, including critical patient venous channel, in Cardiac vein surveys pressure, nutrition infusion, interventional therapy, Chemotherapy of Tumor Patients and hemodilution and controlled hypotension.But in practical behaviour During work, by the limitation of its routine techniques and pricking device, subclavian vein puncture complication (as damage pleura, artery and Nerve) incidence 2 ~ 6%, carry out certain difficulty to carry out clinical diagnosis and treatment work belt, be unfavorable for lapsing to for patient.

Staight needle is clinically commonly used as puncture needle row subclavian vein puncture, in addition the syringe that tail end connects therewith, from wearing The tip of pricker is to the tail end of syringe, and length is greater than 15cm.In puncture process, too long pricking device (puncture needle, connection Device and syringe) limited by the wall of the chest and shoulder, puncture needle cannot keep during inserting needle it is parallel with clavicle, with puncture needle Go deep into, easily downwards damage pleura cause pneumothorax generation, accidentally injure artery cause local hematoma even hemothorax generation, seriously Jeopardize patient safety, brings greater risk to clinical manipulation, and extend the hospital stays, cause certain economic loss.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of Y shape bend pipe connectors, so that wearing in subclavian vein In the operating process of thorn, the syringe that tail end is attached thereto effectively avoids the limit of the wall of the chest and shoulder in upward or state obliquely System, it is ensured that puncture needle state with clavicle keeping parallelism always during inserting needle utmostly reduces complication (such as damage chest Film, artery and nerve) generation.

In order to solve the above technical problems, the technical problem to be solved by the present invention is to provide a kind of Y shape bend pipe connector, Including Y shape bend pipe connector body, inside there is straight through tube；Arc-shaped bend is presented in the head end of Y shape bend pipe connector body, and head end connects Connect puncture needle；The tail end of Y shape bend pipe connector body is a Y-shaped bifurcated mouth, is divided into two connectors, wherein the first connector Connect syringe；Second connector is an open pipe.

10 ° of the crooked radian > of the Y shape bend pipe connector head end and 90 ° of <.Preferably, the Y shape bend pipe connector 30 ° of the crooked radian > of head end and 60 ° of <, it is more preferred, the crooked radian of the Y shape bend pipe connector head end be 30 ° or 45 ° or 60 °.Optimal, the crooked radian of the Y shape bend pipe connector head end can be 60 °.

As the preferred technical solution of the utility model, the angular range of first connector and second connector For 30 ° of > and 60 ° of <.

As the preferred technical solution of the utility model, second connector is an open pipe, is placed in guide wire Pass through.

As the preferred technical solution of the utility model, first connector is covered by needle cap, after needle cap is removed in rotation External syringe.

As the preferred technical solution of the utility model, the terminal of the head end is puncture needle connector, outer diameter and often The internal diameter for advising deep vein puncture needle connector is identical.

As the preferred technical solution of the utility model, the syringe is in upward or diagonal upward direction.The syringe is upward Or angular range obliquely is 10 ° of > and 90 ° of <.

As the preferred technical solution of the utility model, second connector is an open pipe, which hangs down It is straight upward.

The utility model has the beneficial effects that: arc-shaped bend is presented in the head end of Y shape bend pipe connector, so that being attached thereto Syringe direction the state of upward or oblique top is presented, effectively avoid the limitation of the wall of the chest and shoulder, ensure during inserting needle Always the state with clavicle keeping parallelism, the risk for avoiding puncture needle more deeper more downward utmostly reduce damage chest to puncture needle The generation of film, artery and nerve.Arc-shaped bend position internal diameter is uniform, internal run-through pipeline space is sufficient, it can be ensured that guide wire It is smoothly current, it is unobstructed；The utility model is good with inserting needle plane controllability, subclavian vein puncture directive property is strong, deep Tissue punctures the low advantage of incidence, to improve puncture success rate, reduce complication rate.This Y shape bend pipe connector knot Structure is simple, it is easy to make, be suitable for clinical application.

Specific embodiment

By taking subclavian vein catheterization as an example, as depicted in figs. 1 and 2, a kind of Y shape bend pipe connector of the utility model is Puncture the coupling part between staight needle (conventional deep vein puncture needle 4) and syringe 8 comprising Y shape bend pipe connector body 1, it is interior There is straight through tube；Arc-shaped bend is presented in the head end 2 of Y shape bend pipe connector body 1, and radian is 60 degree, and the terminal of head end 2 is to wear Pricker connector 3, outer diameter are identical as the internal diameter of conventional deep vein puncture needle connector 41；The tail of Y shape bend pipe connector body 1 End 5 is a Y-shaped bifurcated mouth, is divided into two connectors, wherein the first connector 6 is covered by needle cap, it is rotatable remove needle cap after External syringe 8；Second connector 7 is an open pipe, and vertically upward, open pipe can be led to the open pipe by guide wire It crosses.The angular range of first connector 6 and the second connector 7 is 30 ° of > and 60 ° of <.Syringe 8 is in upward or diagonal upward direction, The angular range of syringe 8 upwards or obliquely is 10 ° of > and 90 ° of <.

As shown in figure 3, the utility model can (puncturing staight needle, the utility model, syringe) work one that pricking device is whole Arc-shaped bend is effectively avoided being worn so that the state of upward or oblique top is presented in the syringe 8 that the utility model tail end 5 connects The limitation of thorn person's wall of the chest and shoulder.Puncture needle 4 is successively pierced into the gap below clavicle with first rib, is worn by skin, subcutaneous tissue Pricker 4 during avoiding 4 inserting needle of puncture needle, can puncture deep tissue, damage chest most possibly with clavicle keeping parallelism state A possibility that film, artery, nerve.

The utility model piercing method, routine disinfection drape, layer-by-layer infiltration anesthesia near 1% lidocaine 2ml point of puncture, By the utility model with puncture after staight needle and syringe be connected, using linea medioclavicularis outside, 1.5cm is entry point under clavicle, along clavicle Axis inserting needle, needle body press to the wall of the chest, and 45 ° of piercing clavicles in the following, left hand holds the arcuate curvature of the utility model, hold by the right hand Syringe 8 is in negative pressure state, slowly the horizontal inserting needle below clavicle, after syringe pumpback has blood, puncture needle is prompted to enter under clavicle Vein, the fixed the utility model of left hand, the right hand are placed in guide wire, the utility model arcuate curvature from the second connector 7 Internal run-through internal diameter of the pipeline is uniform, space is sufficient, therefore guide wire can smooth merging and without any resistance.Fixed and reservation is led Draw steel wire, exit puncture needle, be placed in central venous catheter along guide wire, catheter retaining suitable length exits guide wire, leads External syringe is managed, after pumpback has blood, external fluid infusion, point of puncture part suture needle is fixed, and aseptic dressing covering, puncture procedure is completed.
