Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] As shown in the figure, the left half of the puncture needle core 1 is the handle 4, the right half of the puncture needle core 1 is the elongated needle 3, the left end of the puncture sheath 2 is the handle 5, and the right side of the handle 5 is the elongated thin-walled circle. Barrel 7, a side opening 6 is opened in the axial direction on one side of the circumference of the thin-walled cylinder 7.

[0014] When in use, set the puncture needle core 1 and the puncture sheath 2 together, hold the handle 4 and puncture the patient's chest cavity, withdraw the puncture needle core 1 after the puncture is successful, leave the puncture sheath 2 on the patient's chest wall, and drain the Y-shaped The tube is inserted into the chest cavity through the puncture sheath 2, and finally the puncture sheath 2 is withdrawn. Therefore, the Y-shaped tube can be left in t...

Abstract

A thoracentesis drainage needle having a side opening comprises a puncture needle core and a puncture sheath, wherein the left half part of the puncture needle core is a handle; the right half part of the puncture needle core is a long and narrow pinhead; the left end of the puncture sheath is a holding part; the right side of the holding part is a strip-shaped thin walled cylinder; and a side opening is arranged on one side of the periphery of the thin walled cylinder along the axial direction. The thoracentesis drainage needle solves the problems that the thoracentesis needle in the prior art is inconvenient to use and increases the patient pain. The thoracentesis drainage needle is fit for thoracentesis drainage.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a thoracentesis needle device. Background technique [0002] At present, the traditional Y-shaped thoracentesis needle is inconvenient to hold and exert force when inserting the needle, so only a straight drainage tube with a thinner diameter can be placed, and the puncture needle needs to be withdrawn after each puncture, and the puncture must be repeated when necessary , causing misery to the patient, moreover can not place Y-shaped drainage tube, can not drain while flushing. Contents of the invention [0003] The present invention provides a split-type puncture needle with a side opening in order to solve the problems that the current thoracentesis needle is inconvenient to use and increases the suffering of patients. [0004] The technical solution of the present invention is a side-opening chest cavity puncture drainage needle, which is special in that it includes a pu...
