Description

Deep vein puncture needle under clavicle

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of medical instrument technique and specifically relates to a deep vein pjncture needle under collar-bone.

[ background of the invention ]

Deep vein catheterization refers to a process of inserting a deep vein catheter into a corresponding vein through body surface puncture, and the frequently selected deep vein comprises a femoral vein, an internal jugular vein or a subclavian vein. Because the position is selected to dark vein and most is adjoint with the artery, medical operation personnel need avoid the mistake to penetrate the artery when carrying out dark venipuncture to the patient, in case the mistake penetrates the artery and does not in time stop the operation, can lead to hematoma, bleedings when extubating etc. and endanger the life even, often need surgery operation/intervention operation to repair the artery, increase patient's mortality.

The needle point of dark vein pjncture needle all generally is provided with the inclined plane, when puncturing dark vein, especially at puncture subclavian vein, the in-process of internal jugular vein, pjncture needle mouth direction need keep down, nevertheless need adjust pjncture needle direction and degree of depth at the puncture in-process, and can't confirm the needle mouth direction of puncture needle when the syringe needle enters into the patient internally, will cause puncture direction mistake easily like this, so not only increase medical personnel work load, there is medical risk simultaneously, cause patient's unnecessary misery, for this dark vein pjncture needle under the subclavian is provided specially.

The Chinese patent application: CN202128515U discloses a deep vein puncture outfit, which comprises a needle tube, a needle head, and a guide wire, wherein the needle tube is connected with the needle head through a connecting tube, the connecting tube is provided with a side tube, the guide wire is slidably located on a guide wire supporting component, a seal film is arranged at a guide wire insertion end of the side tube, a tapered tube is arranged at an end of the guide wire supporting component, and the guide wire passes through the tapered tube. This dark venipuncture ware is when using, carry out the venipuncture back with the syringe needle, only need puncture through the sealed film on the conical duct on the seal wire supporting component with the side pipe, make the conical duct insert the side intraductal, remove the seal wire and can make it pass through the syringe needle along the side pipe and enter into the vein, operate very simple, convenient, medical personnel can very quick completion puncture operation, can furthest avoid the syringe needle to shift, improve the success rate of puncture, reduce patient's misery, also can effectively avoid patient's unnecessary blood loss simultaneously. However, the device is not provided with a structure capable of judging the direction of the needle opening of the puncture needle, the connection between the needle head and the injector is unstable, the needle is easy to rotate and drop when the direction and the depth of the puncture needle are adjusted, the hand feeling of puncture medical staff is easy to damage in the rotating state, the needle head is more polluted by dropping, and medical resources are wasted when the puncture fails.

In summary, there is a need for a deep subclavian vein puncture needle that not only allows medical staff to determine the direction of the needle opening of the puncture needle, reduces medical risks caused by wrong puncture direction, but also prevents the needle head from rotating and falling easily during adjustment of the puncture needle during the puncture process, thereby not affecting the puncture state of the operator.

[ summary of the invention ]

The utility model aims at providing a, provide one kind and can not only let medical staff judge pjncture needle mouth direction, reduce because of the medical risk that the puncture direction mistake caused, can also not take place to rotate and drop easily for the needle head when the puncture needle is adjusted to the puncture in-process to deep vein pjncture needle under the collar bone that does not influence operating personnel puncture state.

In order to achieve the purpose, the utility model adopts the technical proposal that:
