Abstract
The utility model relates to a disposable myeloid puncture needle, comprising a needle body (1) and a needle core (2), wherein, the outside diameter of the needle stem part (3) on the needle body (1) is 0.7 to 0.9mm, the diameter of the stem part (4) on the needle core (2) is 0.3 to 0.5mm, a chimeric orifice (6) for preventing the rotation displacement is arranged between the needle pintle part (7) of the needle body (1) and the needle pintle part (5) of the needle core (2), the needle body handle (8) is arranged on the outer side position of the connection between the needle pintle part (7) and the needle stem part (3) of the needle body (1), the needle core handle (9) or circular cylinder (10) are arranged on the tail end of the needle pintle part (5) of the needle core (2). The utility model has the advantages that the myeloid puncture needle is with simple and rapid operation, high success rate, aimed at the small tissue damage, need not anesthetic and application after operation, the needle head can not be blocked, in particular to be suitable for bone marrow puncture of children and infant below 15 years old.
Description
Technical field
This utility model belongs to medical apparatus and instruments, specifically belongs to medical puncture needle.
Background technology
At present the bone marrow aspiration inspection is done by each hospital, mainly adopts No. 16 and No. 12 marrow puncture needles carry out bone marrow aspiration and draw materials.Be used for the adult for No. 16, be used for the child No. 12, the external diameter of its pin stalk is respectively 1.6mm and 1.2mm, is the reusable medical apparatus and instruments in sterilization back.Because its puncture needle is thicker, bigger to patient trauma, need under local anesthesia, operate, the operating time is longer, and part child particularly infant often lacks cooperation or can not the long period compounding practice, and it is unsuccessful easily to cause puncture to be drawn materials.
In order to shorten the operating time, we once adopted disposable 5ml and 10ml syringe directly to carry out ilium and sternoparacentesis to child below 15 years old and infant.Owing to be No. 7 or No. 8 syringe needles, belong to fine needle aspiration, little to tissue injury, need not use anaesthetic, obviously shortened the operating time, improved puncture success rate.But the phenomenon of syringe needle appears stopping up in the part patient in piercing process, and promptly when puncture needle thrust cortical bone, sclerotin in the cortical bone or cartilage entered in the syringe needle, makes syringe needle by all or part of obstruction, and the amount that can not extract bone marrow fluid or extraction out very little.Sometimes need change syringe needle punctures once more and draws materials.
Summary of the invention
The purpose of this utility model provides the disposable tiny type marrow puncture needle of a kind of confession with nook closing member, being used for bone marrow aspiration draws materials, it is little that it is had tissue injury, can effectively avoid syringe needle to stop up and cross infection, and can make the bone marrow aspiration operating process obtain simplifying, shorten the operating time, improve puncture success rate.
Concrete scheme of the present utility model is: this disposable marrow puncture needle, form by needle body (1) and nook closing member (2), pin stalk portion (3) outer that it is characterized in that needle body (1) through being 0.7～0.9mm, in nook closing member (2) is arranged, the diameter of the stalk portion (4) of nook closing member (2) is 0.3～0.5mm, and it is pointed or coniform pointed that needle point is the inclined-plane; The pin stalk portion (3) of needle body (1) and the stalk portion (4) of nook closing member (2) are made of metal, and the pintle portion (7) of needle body (1) and the pintle portion (5) of nook closing member (2) can be made by metal or plastics; Chimeric mouthful (6) preventing rotation displacement are arranged between the pintle portion (5) of the pintle portion (7) of needle body (1) and nook closing member (2), and chimeric mouthful (6) can be groove shape, bayonet socket shape or L shaped rail-like; Outside left in the pintle portion (7) of needle body (1) and the junction of pin stalk portion (3) can have needle body handle (8), afterbody in the pintle portion (5) of nook closing member (2) can have nook closing member handle (9) or cylinder (10), handle (8) can be rectangle, and handle (9) can be circle or rectangle.
The profile of this utility model puncture needle has two kinds: a kind of is that the entire length of puncture needle is 6～8cm, and the pintle portion of needle body and nook closing member is handle-shaped (seeing accompanying drawing 1); Can be not with handles yet.Another kind is that the entire length of puncture needle is 5～7cm, the pintle portion of nook closing member is built-in be conical (seeing accompanying drawing 2), short and small suitable, just in time the pars papillaris with syringe contacts, and the pintle portion of nook closing member is cylindrical to outer lug, rough surface, to increase frictional force, length is isometric with the pars papillaris of join syringe, but thin slightly than the internal diameter of syringe nipple, and syringe serves as handle during the puncture of band nook closing member.Various puncture needle also can all be made of metal.
Using method and operating process: the local skin routine disinfection, after the handle of hand-held puncture needle thrusts medullary cavity (sense that falls through is arranged) with puncture needle, extract nook closing member out, put syringe and extract bone marrow fluid, after pulling out pin, push with the iodine tincture cotton balls and to get final product in 5～10 minutes, need not apply ointment or plaster.This utility model is suitable for child below 15 years old and infant ilium, sour jujube bone and sqternal puncture, adult's sqternal puncture, part adult's ilium puncture.
Use this utility model puncture needle to be used for bone marrow aspiration and draw materials, little to tissue injury, easy to use, the operating time is short, does not stop up syringe needle.Through 30 many cases clinical practices, respond well, the success rate of drawing materials is 100%.
