Detailed Description
Referring to fig. 1 to 3, a disposable blood collection transfer device includes a blood collection tube puncture needle assembly 1, a connection hose 2 and a culture tube puncture needle assembly 3 fixed in series.
The blood collection tube puncture needle assembly comprises a needle seat 13, a needle seat sleeve 12 is fixed at the rear end (the left end in the drawing) of the needle seat 13, a needle tube 11 is arranged in the needle seat sleeve 12, the front end of the needle tube 11 extends to the outer side of the needle seat sleeve 12, the rear end of the needle tube 11 is fixed on the needle seat 13, an air channel 16 which is communicated with the outside and is radially arranged is arranged on the needle seat 13, a channel A is arranged in the needle tube 11, a gap between the outer wall of the needle tube 11 and the needle seat sleeve 12 is a channel B, an air plug 15 is fixed at the outer end part of the air channel 16, an air filtering membrane 14 is fixed at the inner side of the air plug 15 on the air channel 16, a blood flow channel is arranged in the needle seat 13, the inner end part of the air channel 16 axially extends towards the side of the needle seat sleeve 12, one channel of the channel A and the channel B is communicated with the other channel of the channel A and the, A blood flow passage communicating passage B), and a needle sheath 4 for protecting the needle tube 11 is fixed outside the needle tube.
The culture tube puncture needle assembly 3 comprises a puncture needle seat 31, a bleeding needle tube 32 is fixed on the puncture needle seat 31, a hemostatic sleeve 5 is arranged outside the bleeding needle tube 32, and the hemostatic sleeve 5 is fixed on the puncture needle seat 31.
