Abstract
The utility model relates to an infantile vein blood taking needle, belonging to the technical field of medical apparatus and instruments; the infantile vein blood taking needle is composed of a test tube, a sealing cover, a soft tube, a puncture needle, a pintle an a piston; the infantile vein blood taking needle is characterized in that: the outer wall is provided with a test tube opening with a ring-shaped bulge and the outer part is connected with a sealing cover with a soft tube above the sealing cover in a threaded sealing way, one end of the soft tube is communicated with the inner cavity of the test tube, and the other end is connected with the puncture needle with a handle; the pintle penetrates through a through hole above the bottom part of the test tube and is fixedly connected with the piston in the test tube, and a break-off flute mark is arranged on the pintle close to the position of the piston; as a section of the soft tube is additionally arranged between the puncture needle and the test tube, the adjustment range of the inserting needle angle of the puncture needle is increased, the infantile vein blood taking needle is suitable for infantile struggling action, the needling difficulty is remarkably reduced and the operation accuracy is improved; in addition, the collected blood can enter in the test tube directly without damaging blood sample cells, and blood pollution is avoided.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of child vein blood taking needle.
Background technology
At present, the apparatus that the child vein blood sampling is used still is a syringe mainly, when taking a blood sample, because the syringe external diameter is thicker, has limited needle angle, the quality of whole needle body is bigger in addition, swing is difficulty also, is difficult to adjust the orientation with children's's the struggle of crying and screaming, and causes the inserting needle difficulty to strengthen; The blood sample of Cai Jiing also will move into test tube more simultaneously, and formality is loaded down with trivial details, and operation inconvenience when test tube moves into blood sample, destroys the blood sample cell easily and causes blood sample to pollute.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of needle angle adjusting range big, and the blood of being gathered can directly enter the child vein blood taking needle of test tube.
The purpose of this utility model is achieved in that this child vein blood taking needle is made up of test tube, seal cover, flexible pipe, puncture needle, pintle, piston, above being tightly connected, the test tube mouth external screw-thread that outer wall is provided with annular protrusion is provided with the seal cover of flexible pipe, flexible pipe one end communicates with the test tube inner chamber, and the other end links to each other with the puncture needle that has handle; The through hole that pintle passes above the test tube bottom is fixedlyed connected with invisible spectro piston, and the pintle at close piston place is provided with the flute mark that fractures.
After puncturing successfully, pulling back pintle can be drawn into blood in vitro by flexible pipe, then piston is moved to the test tube bottom, from the flute mark that fractures pintle is fractureed, can be with invisible spectro blood censorship after seal cover being laid down at last again.
Advantage of the present utility model: owing to increased by one section flexible pipe between puncture needle and the test tube, make the adjusting range of puncture needle needle angle increase, can adapt to children's's struggle action, significantly reduce the acupuncture difficulty, improve the operation accuracy rate; And the blood of being gathered can directly enter test tube, can not destroy the blood sample cell, avoids blood to be polluted.
