Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model using state structure diagram.
Specific embodiment
As shown in the picture, the utility model includes conduit 2, catheter block 3 and other adapter tube 4, and one end of conduit 2 is conehead, is leaned on
Multiple holes 5 are provided on 2 tube wall of conduit of nearly conehead one end, the conduit 2 close to the other end is equipped with water pocket 6, the two sides of catheter block 3
It is respectively equipped with handle 11, puncture needle through hole and water pocket water injection hole are had on catheter block 3, and in puncture needle through hole and water
One end of capsule water injection hole is equipped with rubber plug 7, and the conduit 2 and catheter block 3 close to water pocket 6 one end are affixed, and wear with catheter block 3
Pricker through hole communicates, and water pocket 6 is communicated by pipeline 12 with the water pocket water injection hole of catheter block 3, and catheter block 3 is equipped with and puncture needle
The other joint chair 8 that through hole communicates, other 4 one end of adapter tube are connected by other joint chair 8 and catheter block 3, and other 4 other end of adapter tube is equipped with threeway
Connector 9, other adapter tube 4 are equipped with flow-stopping clip 10.
Rubber plug 7 is transparent plug, and puncture needle through hole and water pocket water filling hole location are respectively equipped on rubber plug 7
Indicating grooves are set, and are equipped with guide line 13 in the rubber plug 7 of corresponding water pocket water filling hole site.
The pore size in multiple holes 5 is different.
Water pocket 6 is annular, is provided with a circle water pocket mounting groove on conduit 2,6 sets of water pocket in slot.
Pipeline mounting groove is provided on conduit 2, pipeline 12 is located in slot.
Handle 11 is butterfly handle, and has one group of hole in butterfly handle end.
Working method and principle: before puncture, syringe needle one end of puncture injector 1 is inserted into conduit 2, puncture injector 1
Syringe needle punctures blood vessel, and guiding catheter 2 is inserted into intravascular, until water pocket 6 is fully located at intravascular, extracts puncture injector 1
Syringe needle, one end of conduit 2 are conehead, and conehead is circle, and conduit 2 is the plastic pipe of flexible, stop in the blood vessels may be used for a long time
To avoid blood vessel is punctured, then by brine injector pump pickle into water pocket 6, expand water pocket 6, play blocking and
Fixed function prevents conduit 2 from falling off, and is then fixed by adhesive tape handle 11, rubber plug 7 is in 1 He of puncture injector
Brine injector syringe needle can be closed automatically after extracting, and anti-Hemostatic Oral Liquid and salt water outflow open flow-stopping clip 10 and be infused.Carry out
When haemodialysis, using two remaining needles, one is inserted into intra-arterial, one be inserted into it is intravenous, two remaining needles
