Abstract
The utility model discloses a puncture needle, which relates to the technical field of medical appliance, which comprises a puncture needle head and a needle base. The rear of the needle base is connected with a three-way pipe; the three-way pipe comprises a straight pipe directly communicated with the puncture needle head and a bypass straight pipe; the straight pipe is provided with a needle plug and the three-way pipe is connected with an injector or a liquid storage device by the needle plug; the external surface of the puncture needle is marked by a millimeter scale line; the bypass straight pipe is provided with a container with an upper valve and a lower valve; the container is marked by a volume scale line. As the structure is adopted, the puncture needle of the utility model, compared with the prior art, is good for doctors to control the depth of the puncture needle and directly measure the outflow of cerebrospinal fluid.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of puncture needle that is used for internal medicine.
Background technology
China utility model patent ZL02212592.2 discloses a kind of puncture needle, this puncture needle is made up of piercing needle and needle stand, be connected with tee T behind the needle stand, tee T comprises straight tube and a bypass straight tube straight-through with piercing needle, be equipped with pin on two arms and fasten, tee T is fastened by pin and is connected syringe or device for storing liquid.
The puncture needle of above structure, though simple in structure, the doctor is difficult to hold the depth of needle of puncture needle in use, and can not directly measure the discharge of cerebrospinal fluid, easily causes increasing patient's misery.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and depth of needle that a kind of doctor of being convenient to grasps puncture needle and the puncture needle that can directly measure the csf flow output are provided.
This utility model is made up of piercing needle and needle stand, be connected with tee T behind the needle stand, tee T comprises straight tube and a bypass straight tube straight-through with piercing needle, straight tube is provided with pin and fastens, tee T is fastened by pin and is connected syringe or device for storing liquid, and described puncture needle outer surface is marked with a millimeter graduation mark; A container that is provided with upper and lower valve is set on described bypass straight tube, and this container is marked with content line.
This utility model compared with prior art has and is convenient to the advantage that the doctor grasps the depth of needle of puncture needle and can directly measure the csf flow output owing to adopt above structure.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is elaborated:
As shown in drawings, this utility model is made up of piercing needle 1 and needle stand 2, be connected with tee T 3 behind the needle stand, tee T comprises straight tube 4 and a bypass straight tube 5 straight-through with piercing needle, straight tube is provided with pin and fastens 6, tee T is fastened by pin and is connected syringe or device for storing liquid, and described puncture needle outer surface is marked with a millimeter graduation mark; A container 7 that is provided with upper and lower valve is set on described bypass straight tube, and this container is marked with content line.
When the doctor uses this utility model, open valve, close down valve, cerebrospinal fluid flows in the container, can read flow easily by the volume line on the container; When puncture, can grasp the depth of needle of puncture needle in addition by the millimeter graduation mark that the puncture needle outer surface is marked with.
