Description
Technical field this utility model belongs to department of pediatrics clinical treatment apparatus, mainly proposes a kind of clinical children's's of using puncture needle.
Background technology this utility model is applicable to puncture under the dura mater of premature infant, neonate, infant etc., bone marrow aspiration, lumbar puncture.Marrow puncture needle is conventional model clinically now, does not have children's to use pin.Children's is because medullary cavity is little, and cortical bone is thin, and paracentesis depth is shallow, and the conventional type marrow puncture needle is big because of volume, syringe needle thick, Heavy Weight, can not fix when children's uses, and often makes puncture failure.Puncture does not now have specific purpose tool under children's's dura mater, and No. 7 injection needles of many clinically employings puncture, and because of syringe needle does not have nook closing member, and pinpoint inclined plane is unreasonable, easily stops up syringe needle or penetration damage angiorrbagia, thereby causes puncture failure.
The summary of the invention the purpose of this utility model is to propose a kind of clinical children's's of using puncture needle, with the problem that solves puncture under clinical children's's dura mater, bone marrow aspiration and lumbar puncture and make it have the advantages that a pin is used more.
The technical scheme that the utility model proposes is: it has nook closing member and needle guard two parts, the core body of nook closing member front end penetrates the body of needle guard front end cavity structure, the head of core body and body is ramp structure, for guaranteeing the concordance on their inclined-planes, on the nook closing member body of nook closing member rear end, alignment pin is set, on the needle guard body of needle guard rear end, set locating slot, make the corresponding locating slot that snaps in the needle guard body of alignment pin of nook closing member body behind needle guard and the nook closing member fit, even the inclined-plane unanimity of their front end heads, thereby damaged tissue and stop up pinprick when preventing to puncture.
Core body with the nook closing member front end during use penetrates in the body of front end, and the alignment pin correspondence is snapped in the locating slot, and their head promptly has consistent inclined-plane, when puncture reaches predetermined position, extract nook closing member portion, liquid can excrete along needle guard, reaches the purpose of Clinics and Practices.
This utility model is simple in structure feasible, can reduce the painful and treatment delay of the infant that causes because of puncture failure in the use, is adapted to the puncture of various positions, has the advantages that a pin is used more.
Appended drawings 1 is this utility model structural representation.
The specific embodiment as shown in Figure 1, it comprises nook closing member and needle guard two parts, the core body of nook closing member front end (5) penetrates the body (4) of needle guard front end, body (4) is a cavity structure, core body (5) and body (4) head are ramp structure, the nook closing member body (1) of nook closing member rear end is provided with alignment pin (3), sets locating slot on the needle guard body (2) of needle guard rear end, and the alignment pin (3) of nook closing member body is snapped in the locating slot of needle guard body (2).
