Abstract
The utility model discloses a puncture needle with a negative pressure sucker. The puncture needle is composed of a needle tube, a needle tube sleeve, a needle core and a needle handle. The needle tube is fixed on the needle tube sleeve, the needle core is fixedly connected with the needle handle, the needle core is inserted in the needle tube, a bypass port is formed in the side wall of the needle tube sleeve and connected with the negative pressure sucker, and the capacity of the negative pressure sucker is 2ml. After bone marrow puncture operation is successfully conducted, when bone marrow is extracted to be tested, the needle core is slowly pulled out to make the bypass port be communicated with the needle tube, at the moment, the bone marrow can automatically flow to the negative pressure sucker, after the negative pressure sucker is filled with the bone marrow, the needle core is pushed to the original position, and the bone marrow extraction operation is finished. Therefore, the operation is easy and convenient to conduct, and the effect for extracting the bone marrow is greatly improved.
Description
Technical field
This utility model relates to a kind of puncture needle with negative pressure straw.
Background technology
The puncture needle of lumbar puncture art use at present is made of needle tubing, needle tubing cover, nook closing member and needle handle, needle tubing is fixed on needle tubing and puts, nook closing member is fixedly connected with needle handle, nook closing member inserts in needle tubing, when bone marrow extraction is chemically examined, because will dial except nook closing member, then connect syringe and come bone marrow extraction, because the capacity of bone marrow extraction is difficult to control, make troubles to the operator.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of easy to operate, can automatic accurate extraction the puncture needle of quantitative bone marrow.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of puncture needle with negative pressure straw, consisted of by needle tubing, needle tubing cover, nook closing member and needle handle, needle tubing is fixed on needle tubing and puts, nook closing member is fixedly connected with needle handle, nook closing member inserts in needle tubing, offers the bypass interface on described needle tubing cover sidewall, and the bypass interface is connected with negative pressure straw.
The capacity of described negative pressure straw is 2ml.
The advantage of puncture needle of the present utility model is: after the success of bone dress operation, when bone marrow extraction is chemically examined, nook closing member is slowly pulled out, the bypass interface is communicated with needle tubing, and this moment, bone marrow was with regard to energy automatic stream negative pressure straw, after being full of negative pressure straw, nook closing member is pushed back the origin-location, complete the bone marrow extraction operation, make like this operation very simple and convenient, greatly improve the efficient of bone marrow extraction.
