The internal diameter of vacuum blood collection tube matches, and gasket is located at below body of the bottle lid, and gasket and body of the bottle lid are structure as a whole, the
The tip end of two needle bodies is mounted on inside the second needle body installing pipe.
The vacuum blood collection bottom of the tube is equipped with liquid volume scale layer, is sleeved on body of the bottle lid at the top of vacuum blood collection tube
Bottom, the outer diameter of vacuum blood collection tube and the internal diameter of body of the bottle lid match, and vacuum blood collection tube and body of the bottle lid use the side of screw thread
Formula is connected.
The utility model beneficial effect is: firstly, this product is equipped with the branch pipe and calparine cap being connected with conduit, by outer
The disposable needle tubing in portion can be inserted in conduit system, increases the negative pressure in conduit by the use of needle tubing and realizes blood from blood vessel
Extraction, be easy to observe whether the first needle body is correctly punctured in vein blood vessel；Secondly, being equipped with needle on the outside of the first needle body of this product
The wing, the grasp of the convenient piercing angle to needle body, is easy to use；Again, this product is equipped with sealing at the top of vacuum blood collection tube
Pad, vacuum blood collection tube facilitate storage using the negative pressure system for being preceding easy to keep in vacuum blood collection tube；Finally, the second needle of this product
