Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of puncture needle that is used to extract cerebrospinal fluid, injection through vertebral canal medicine.
Background technology
At present, medically to cerebral hemorrhage, or encephalitis is made a definite diagnosis, or canalis spinalis implements injectable drug, generally uses the lumbar puncture needle of single opening, and elder generation's local injection anesthetics is puncturing during operation, the medical worker rule of thumb determines the degree of depth of puncture with feel, and then take out nook closing member and extract cerebrospinal fluid, or measure intracranial pressure, or implement the spinal injection medicine.Since conversion needle tubing repeatedly on the puncture needle opening, complex operation, and the operating time is long, and infection easily, brings wound to the patient easily, has increased danger.
The utility model content
The purpose of this utility model is in order to solve the deficiency of aforesaid operations technology, to provide a kind of reasonable in design, simple in structure, the lumbar puncture needle of being convenient to operate.
The technical scheme that the invention for solving the technical problem adopted is: lumbar puncture needle is by syringe needle and the needle handle that is attached thereto, and the side opening flexible pipe that links to each other with needle handle is formed, syringe needle is provided with scale, is provided with nook closing member in the syringe needle, and the opening of needle tubing side opening flexible pipe is provided with and seals medicated cap.
The beneficial effects of the utility model are: reasonable in design, simple in structure, be convenient to operation, and reached the shortening operating time, reduce the dangerous purpose of operation.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1,1. syringe needle, 2. needle handle, 3. after-opening, 4. the side opening flexible pipe 5. seals medicated cap.
The specific embodiment
As shown in Figure 1, a kind of lumbar puncture needle, syringe needle 1 is connected with needle handle 2, be provided with nook closing member in the syringe needle 1, syringe needle 1 is provided with scale, and scale one lattice are for being 0.5mm, be used to control depth of needle, needle handle 2 sidewalls are provided with a side opening flexible pipe 4, and needle handle 2 is the threeway shape, and the opening part of side opening flexible pipe 4 is provided with one and seals medicated cap 5.During use, 1 on puncture needle pin is inserted in the lumbar vertebral canal, by the control of the scale on the syringe needle 1 depth of needle, extract nook closing member out, extract cerebrospinal fluid out from the after-opening 3 of needle handle 2 and be used for check, perhaps inject medicines and treat, seal medicated cap 5 by side opening flexible pipe 4 from after-opening 3, take out and connect intracranial pressure table, the variation of sustainable monitoring intracranial pressure.
