Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of disposable children's's sternal puncture needle.
Background technology
The traditional method of children's's sternoparacentesis is to use sternal puncture needle to accomplish; Though a plurality of models are arranged, be directed to characteristics such as the infant medullary cavity is little, cortical bone thin, paracentesis depth is shallow, pain sensitivity height, its equal syringe needle is thick, damage is big, the inclined-plane is little; Puncture is firmly big; Be difficult for holding firmly size and paracentesis depth, breastbone is thin in addition, and easy mistake penetrates vertical diaphragm and heart.
Summary of the invention
The purpose of this utility model is to provide a kind of disposable children's's sternal puncture needle.
The purpose of this utility model is achieved in that disposable children's's sternal puncture needle, comprises syringe needle and flexible pipe, it is characterized in that said syringe needle links to each other with said flexible pipe, is provided with syringe interface at the end of said flexible pipe.
Said syringe needle select for use No. 7 or No. 9 syringe needles all can, purpose is that damage is little, puncture is firmly little, painful light, pull out pin after oozing of blood few.
In the tip of said syringe needle is solid, and the top of said tip has pin hole, and purpose is to be stopped up by soft tissue or bone bits when preventing that syringe needle from going deep in the breastbone, causes extracting bone marrow.
Outer surface at said syringe needle is provided with scale, and scale has 3 to be respectively 0.5,1.0,1.5 centimetre and to get final product, and purpose is to control the weight of puncture, avoids damaging blood vessel or heart behind the breastbone.
Afterbody at said syringe needle is provided with handle, and purpose is to carry out inserting needle or to pull out pin easy to operate.
On the body of said flexible pipe, be provided with scale, the length of flexible pipe is 25.5 centimetres, and the intraluminal fluid scale of construction is 0.5 milliliter, gets final product so scale is established five 0.1,0.2,0.3,0.4,0.5 milliliter, and purpose is to be convenient to grasp the marrow amount of taking out.
The utility model has the advantages that: 1, easy and simple to handle, syringe needle can not stopped up by soft tissue or bone bits, and puncture success rate is high, and general one-time puncture operation gets final product; 2, scalp acupuncture is tiny, and syringe needle is sharp, and is painful light during inserting needle, need not anaesthetize, little to the tissue injury that passes, pull out pin after oozing of blood few; 3, the weight of puncture be can control, blood vessel or heart behind the breastbone avoided damaging, safe and reliable; 4, can grasp the amount that extracts bone marrow; 5, the initiation side effect is little.
