Detailed description of the invention
As shown in Figures 1 to 6, the dialysis remaining needle that can stop blooding, comprise dialysis remaining needle draw point pipe 1, be bonded in draw point pipe 1 afterbody draw point seat 2, be entrenched in the tampon 3 of draw point seat 2 afterbodys, and be adhered to the conduit 7 of catheter block 6 one sides, also comprise screwed union sleeve pipe 4, switch connection tube 5, circular rubber cushion 8.
The tube wall of screwed union sleeve pipe 4 one end is provided with one section of Pear-Shaped gap 4-1, in Pear-Shaped gap 4-1, be provided with two spacing, be respectively circular spacing I4-2 and circular spacing II4-3, on the other end outer tube wall of screwed union sleeve pipe 4, be provided with spiral mouth 4-4, on the inner tubal wall of screwed union sleeve pipe 4, be provided with a circle groove 4-5.
The outer tube wall of switch connection tube 5 is provided with a cylindrical boss 5-1, is provided with a rectangle and pushes away handle 5-2 on cylindrical boss 5-1, and cylindrical boss 5-1 and rectangle push away the handle 5-2 part that is formed in one.
Circular rubber cushion 8 is lamellar, is provided with Y-shaped otch 8-1 at circular rubber cushion 8 Mian centers, and Y-shaped otch 8-1 is logical otch.
Circular rubber cushion 8 is bonded in the groove 4-5 on screwed union sleeve pipe 4 inner tubal walls, by bonding cooperation in one end of one end embedding catheter block 6 of switch connection tube 5, in the pipe of other end embedding screwed union sleeve pipe 4 one end of switch connection tube 5, contact with circular rubber cushion 8, rubber cushion 8 is initial in closure state, now the cylindrical boss 5-1 of switch connection tube 5 is arranged in circular spacing I4-2 by Pear-Shaped gap 4-1, part cylindrical boss 5-1 and rectangle push away handle 5-2 and are emerging in outside screwed union sleeve pipe 4, littlely try hard to recommend moving rectangle and push away handle 5-2 and can make cylindrical boss 5-1 slip in circular spacing II4-3, now the other end of switch connection tube 5 makes rubber cushion realize open mode through the Y-shaped otch 8-1 of circular rubber cushion 8, switch connection tube 5 is interference fit with screwed union sleeve pipe 4.1 of the firm needle tubing bonding together with draw point seat 2 is inserted successively in screwed union sleeve pipe 4 and stretched out outside conduit 7 by Y-shaped otch 8-1, switch connection tube 5, catheter block 6 on circular rubber cushion 8, and draw point seat 2 contacts with the other end of screwed union sleeve pipe 4.
Using method
In clinical use, medical personnel pinch draw point seat 2 draw point 1 and conduit 7 are punctured and enter human vas simultaneously, and now, circular rubber cushion 8 is closely enclosed in around draw point 1 because of its whippy material behavior Y-shaped otch 8-1, and this remaining needle is closure state.After puncture puts in place, medical personnel pinch screwed union sleeve pipe 4 on the other hand, another hands pinches draw point seat 2 and slowly extracts draw point 1 out screwed union sleeve pipe 4, draw point 1 detaches in process, and the Y-shaped otch 8-1 of circular rubber cushion 8 forms fine gap around draw point 1, and remaining needle intracavity gas is discharged thus, now blood enters remaining needle tube chamber by conduit 7, when draw point 1 detaches circular rubber cushion 8, the Y-shaped otch 8-1 of circular rubber cushion 8 is automatically closed because of elasticity, and blood terminates in circular rubber cushion 8.After draw point 1 detaches completely, the spiral mouth 4-4 of screwed union sleeve pipe 4 one end is connected with hemodialysis tube pipeline connector.Connect after hemodialysis pipeline, medical personnel pinch switch connection tube 5 on the other hand, another hands pinches screwed union sleeve pipe 4, dial rectangle with forefinger and push away handle 5-2, gently try hard to recommend moving screwed union sleeve pipe 4, cylindrical boss 5-1 slips into circular spacing II4-3 by the spacing I4-2 of circle, and now switch connection tube front end is connected with the hemodialysis tube pipeline connector being connected in screwed union sleeve pipe 4 one end spiral mouth 4-4 through the Y-shaped otch 8-1 in circular rubber cushion 8, forms path.After normal dialysis, medical personnel use styptic cotton to push down puncture orifice, pinch screwed union sleeve pipe 4 and extract the conduit 7 in patient vessel.
