Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of one-handed performance formula venous detaining needle.
Background technology
Tradition venous detaining needle puncture technique needs both hands to closely cooperate to finish, when especially after seeing blood back, withdrawing from nook closing member and sending sleeve pipe, and catheter tip this moment intravasation just, the left hand of immobilized patients unclamps and cooperates right-hand operated easily to cause " race pin ".Especially when puncture children's or neurological patient, can not fully brake and cooperate because of it, when unclamping the left hand cooperation right hand puncture procedure of immobilized patients, normal take place " race pin " causes the puncture and intubation failure, and What is more can cause the doctors and patients personal injury.
The utility model content
The technical problem that this utility model solves just provides a kind of simple to operate, is difficult for running the one-handed performance formula venous detaining needle of pin.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the nook closing member that has head protector and the sleeve pipe that has flank, described sleeve pipe is provided with the springing piece, springing piece rear end has the open draw-in groove in top and is provided with the activation button, the trip that nook closing member is provided with spring and is complementary with the springing piece.
When one-handed performance formula venous detaining needle provided by the utility model did not use, nook closing member passed sleeve pipe, and trip catches on springing piece front end entity place, and spring is compressed.During use, operator's left hand immobilized patients site of puncture or blood vessel, the right hand grip remaining needle sleeve pipe flank and thrust vein blood vessel fast, see behind the blood back more slightly inserting needle a little, guarantee remaining needle cannula tip intravasation.Then, the right hand that grips the remaining needle flank refers to that slightly inwardly roof pressure activates button, the springing piece moves forward, and the open draw-in groove in top, springing piece rear end moves to the trip place, and spring stretches, trip moves to the draw-in groove bottom and blocks again, remaining needle nook closing member front end springs back in the sleeve pipe, and gently insert sleeve pipe along the blood vessel trend this moment, and left hand is pinched needle core trip gently and made trip disengaging springing piece then, extract nook closing member, connect fixedly remaining needle of transfusion device and pad pasting.The remaining needle nook closing member is that front end springs back in the sleeve pipe, is not to eject fully, therefore can not cause nook closing member to pollute even the doctors and patients personal injury.If puncture failure then can promote nook closing member, the nook closing member trip is drawn by the draw-in groove bottom to the draw-in groove top, moved forward, arriving springing piece front end entity place locks with sleeve pipe again, extract the head protector of nook closing member then, fall bloodstain in the nook closing member with the irrigation with syringe that normal saline is housed, continue puncture.
One-handed performance formula venous detaining needle provided by the utility model; returning nook closing member and pushing in the sleeve pipe process and adopt one-handed performance; do not need the openhanded patient of opening of immobilized patients to assist operation; can reduce or stop this moment " race pin "; can improve the puncture and intubation success rate, and simplify the operation, protect doctor and patient.

The specific embodiment
Be described in further details below in conjunction with the concrete structure of accompanying drawing to this utility model one-handed performance formula venous detaining needle.
As shown in Figure 1, the sleeve pipe 1 of one-handed performance formula venous detaining needle provided by the utility model has flank 2, and sleeve pipe 1 is provided with springing piece 3, and springing piece 3 rear ends have the open draw-in groove 4 in top and are provided with activates button 5.As shown in Figure 2, nook closing member 6 has the head protector 7 that prevents hemorrhage, the trip 9 that nook closing member 6 is provided with spring 8 and is complementary with the springing piece.As shown in Figure 3, sleeve pipe 1 has flank 2 and activates button 5, and nook closing member 6 passes sleeve pipe 1, and trip 9 catches on springing piece 3 front end entity places, and spring 8 is compressed.As shown in Figure 4, sleeve pipe 1 has flank 2 and activates button 5, and nook closing member 6 passes sleeve pipe 1, and trip 9 catches on draw-in groove 4 bottoms, and spring 8 stretches.
When one-handed performance formula venous detaining needle provided by the utility model did not use, nook closing member 6 passed sleeve pipe 1, and trip 9 catches on springing piece 3 front end entity places, and spring 8 is compressed.During use, operator's left hand immobilized patients site of puncture or blood vessel, the right hand grip remaining needle sleeve pipe flank 2 and thrust vein blood vessel fast, see behind the blood back more slightly inserting needle a little, guarantee remaining needle sleeve pipe 1 most advanced and sophisticated intravasation.Then, the right hand that grips remaining needle flank 2 refers to that slightly inwardly roof pressure activates button 5, springing piece 3 moves forward, and the open draw-in groove 4 in top, springing piece 3 rear end moves to trip 9 places, and spring 8 stretches, trip 9 moves to draw-in groove 4 bottoms and blocks again, remaining needle nook closing member 6 front ends spring back in the sleeve pipe 1, and gently insert sleeve pipe 1 along the blood vessel trend this moment, and left hand is pinched needle core trip 9 gently and made trip 9 disengaging springing pieces 3 then, extract nook closing member 6, connect fixedly remaining needle of transfusion device and pad pasting.Remaining needle nook closing member 6 just front end springs back in the sleeve pipe 1, is not to eject fully, therefore can not cause nook closing member 6 to pollute even the doctors and patients personal injury.If puncture failure then can promote nook closing member 6, nook closing member trip 9 is drawn to draw-in groove 4 tops by draw-in groove 4 bottoms moved forward, arriving springing piece 3 front end entity places locks with sleeve pipe 1 again, extract the head protector 7 of nook closing member 6 then, fall bloodstain in the nook closing member 6 with the irrigation with syringe that normal saline is housed, continue puncture.
Protection domain of the present utility model not only is confined to above-described embodiment, as long as structure is identical with this utility model one-handed performance formula venous detaining needle, just drops on the scope of this utility model protection.
