Abstract
This utility model relates to medical instruments, specifically a kind of central venous puncture trocar Y-connection and put pipe.For solving the problems of the technologies described above, this utility model solves the technical scheme that its technical problem adopts: a kind of Y-connection of central venous puncture trocar, described Y-connection comprises main adapter and wire leading pipe, main adapter two ends are respectively paracentesis trocar interface end and syringe interface end, wire leading pipe opening direction is near syringe interface end, described wire leading pipe is bending tube, and the bending end opening direction of wire leading pipe is away from syringe interface end.The beneficial effects of the utility model are, when operator uses Y-connection of the present utility model in central venous puncture process, hand operated can be changed, bimanualness is independent of each other, avoid and move at Ink vessel transfusing because changing the paracentesis trocar caused when both hands when hands is fixed mutually touch or change the posture holding syringe, effectively can reduce spike pierces and depart from the risk of blood vessel, central venous puncture is carried out smoothly.
Description
Technical field
This utility model relates to medical instruments, specifically a kind of Y-connection of central venous puncture trocar.
Background technology
Central venous puncture of the prior art puts pipe as shown in Figure 1, wherein Y-connection comprises main adapter and arm, supervisor two ends are respectively paracentesis trocar interface end and syringe interface end, and arm is wire leading pipe, and wire leading pipe opening direction is near syringe interface end one end.Use central venous puncture as shown in Figure 1 to put pipe and carry out venipuncture, when inserting paracentesis trocar, operator's left hand is needed to fix site of puncture and tighten local skin, the right hand is held pin and is punctured, needle point thrusts after blood vessel is shown in smooth and easy blood back, operator with the left hand being originally used for locating, change the fixing hands of fixing puncture needle into, and the right hand originally holding pin need need to take seal wire to insert needle tubing.In this process, the possibility of puncture needle in Ink vessel transfusing movement will occur, because puncture vessel is natively very tiny, slight movement will make spike pierces angiopathy depart from blood vessel, adds puncture failure probability.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency easily causing trocar movement in prior art in central venous puncture operation, provide a kind of Y-connection of novel central venous puncture trocar.
For solving the problems of the technologies described above, this utility model solves the technical scheme that its technical problem adopts: a kind of Y-connection of central venous puncture trocar, described Y-connection comprises main adapter and wire leading pipe, main adapter two ends are respectively paracentesis trocar interface end and syringe interface end, wire leading pipe opening direction is near syringe interface end, described wire leading pipe is bending tube, and the bending end opening direction of wire leading pipe is away from syringe interface end.
As preferably, the angle α of the extended line of the bending end opening direction of described wire leading pipe and the opening direction extended line of syringe interface end is 90 ° ~ 180 °, provides larger working place like this, reduce puncture failure risk to operator.
As preferably, described wire leading pipe bending part is fillet, is conducive in the excessive situation of wire leading pipe bending angle, and when inserting seal wire in central venous puncture process, seal wire can level and smooth intravasation smoothly.
The present invention also provides a kind of central venous puncture of Y-connection of central venous puncture trocar to put pipe, use the Y-connection of above-mentioned central venous puncture trocar, paracentesis trocar is arranged on the paracentesis trocar interface end of Y-connection, syringe is arranged on the syringe interface end of Y-connection, and seal wire inserts paracentesis trocar by wire leading pipe.
As preferably, described paracentesis trocar is fixedly mounted on the paracentesis trocar interface end of Y-connection, and syringe is fixedly mounted on the syringe interface end of Y-connection, and each parts in operating process can be avoided to loosen and slippage owing to installing.
The beneficial effects of the utility model are, when operator uses Y-connection of the present utility model, in central venous puncture process, bimanualness is independent of each other, also hand operated need not be changed, avoid the paracentesis trocar that causes when mutually to touch because of both hands or to change the posture holding syringe in endovascular movement, can effectively reduce the risk piercing through failure, central venous puncture is carried out smoothly.
