Abstract
The utility model relates to a novel lumbar puncture needle which belongs to the technical field of medical equipment and consists of a needle base 1, a connecting part 2, a needle tube 3 and a sheath 4. The angle alpha of a first inclined plane of a needle point is 11+/-2 degrees; and the angle beta of the needle point is 17+/-2 degrees. In addition, the length L from a needle handle to the needle point is 38-43mm, and the distance is short for the fatter school-aged child, so that the length L can be increased to 43mm. The slope of the needle point is reduced, so that the novel lumbar puncture needle is convenient to use and the purpose of reducing the tissue damage is realized. The novel lumbar puncture needle has the advantages of simple structure and wide application range and is convenient to operate, etc.
Description
Technical field
This utility model relates to a kind of novel lumbar puncture needle, belongs to the medical equipment technical field.
Background technology
Traditional lumbar puncture needle needle handle is thin, and the bad assurance of hands departs from the puncture direction easily when doing puncture, and need anaesthetize afterwards earlier and puncture, and the infant misery is bigger.How to take effectively easy injection child lumbar puncture needle, it is the direction of a lot of people's researchs, the child of the hospital lumbar puncture needle of Tui Chuing is also a lot of in the market, but it is mostly more loaded down with trivial details, use and be not very convenient, cause apply extensive inadequately, market be difficult to the exploitation, can not obtain good economic benefit.Needle point is domatic big when adopting disposable syringe to do puncture, and damaged tissue is many, occurs pain in the lumbar region and local discomfort etc. easily.
The utility model content
The purpose of a kind of novel lumbar puncture needle of this utility model is exactly at above problem, and a kind of lumbar puncture needle easily is provided.
The technical scheme of a kind of novel convenient lumbar puncture needle of this utility model: form by needle stand, connecting portion, needle tubing, sheath.Needle stand is connected with needle tubing by connecting portion, and sheath is connected with needle stand, and connecting portion and needle tubing are positioned at sheath.Use a kind of injection child lumbar puncture needle and carry out anesthetic puncture, can carry out inserting needle while anaesthetizing like this, twice breakthrough sense arranged after, pull up needle tubing, the success of can puncturing.A kind of novel lumbar puncture needle needle point first bevel angle α is (11 ± 2 °), and the needle point angle beta is (17 ± 2 °).In addition, a kind of novel lumbar puncture needle needle handle is 38-43mm to the length L of needle point, and for fatter school age child, distance is shorter, be 43mm so when design can increase L.
Beneficial effect: domatic the diminishing of the novel lumbar puncture needle needle point of this utility model kind reaches not only handy but also reduces the purpose of damaged tissue.Have advantages such as simple in structure, easy to operate and applied widely.
