Detailed description of the invention
This venous detaining needle comprises remaining needle body 1, three-way cock 2 and extension tube 3.Remaining needle body 1 is provided with bypass pipe 4, bypass pipe 4 is fixed with extension tube 3, extension tube 3 termination is provided with sleeve pipe 5, and sleeve pipe 5 port is provided with the edge of a wing 6; Extension tube 3 is connected with three-way cock 2 by sleeve pipe.
The three-way cock 2 of this venous detaining needle is made up of sealed tube 7 and sealing column 8, in sealed tube 7, movable sealing is provided with sealing column 8, the top of sealing column 6 extends to sealed tube 7 outer end, sealing column 8 top extending to sealed tube 7 outer end is fixed with swing handle 9, being circumferentially evenly equipped with drug discharging tube 10, adding pencil A11 and add pencil B12 of sealed tube 7.Add pencil A11 and be respectively arranged with the edge of a wing 6 with the port adding pencil B12, add pencil A11 and add on pencil B12 being movably installed with blocking cap 14 respectively by the edge of a wing 6.Blocking cap 14 is in tubbiness, and in blocking cap 14, centre is provided with blocked shot 15, and blocking cap 14 inwall of blocked shot 15 periphery is provided with screw thread.With drug discharging tube 10, add pencil A11 and add in sealing column corresponding to pencil B12 8 and be evenly equipped with multiple intercommunicating pore 13, be interconnected between intercommunicating pore 13, drug discharging tube 10, add pencil A11 and add between pencil B12 and be interconnected by intercommunicating pore 13.
Drug discharging tube 10 is circumferentially provided with boss 16, and drug discharging tube 10 is movably installed with attachment cap 17 by boss 16; Attachment cap 19 inwall is provided with screw thread.The effect of boss 16 prevents attachment cap 17 from slippage drug discharging tube 10.Attachment cap 17 by engaging each other between the edge of a wing 6 on screw thread that inwall is arranged and sleeve pipe 5 port, thus reaches the object that three-way cock 2 is connected with extension tube 3.
The extension tube 3 of this venous detaining needle is movably installed with and regulates card 18; Regulate card 18 to be rectangular plates, regulate the middle part of card 18 to be provided with Tinea Ranae shape adjustment hole 19, the adjustment card 18 of adjustment hole 19 side is provided with otch 20, and otch 20 is communicated with adjustment hole 19.Medicinal liquid flow when regulating the effect of card 18 to be adjustment patient fluid infusion.
This venous indwelling needle construction is simple, and practicality is good, and the pad 21 arranged bottom sealed tube 7 can increase the contact area with patient, prevents impression; Making it drive sealing column 8 to rotate by rotating swing handle 9 in this venous detaining needle use procedure, drug discharging tube 10 can be realized, add pencil A11 and add the object being interconnected between pencil B12 or closing; By add pencil A11 and add pencil B12 be conducive to medicine add temporarily and while multi-medicament input; Solve existing remaining needle due to reasons in structure, it needs to be connected with independently three-way cock in use procedure temporarily, not only complex operation and add the workload of medical personnel, too increases because blood returns the problem of the professional risk that liquid causes medical personnel to pollute simultaneously; This venous detaining needle effectively can reduce workload, facilitates the operation of medical personnel; Be specially adapted to a large amount of continuous transfusion fast of patient use.
