Equipped with draw point seat, top is equipped with needle handle on the right side of the shell；A steel needle, the draw point seat two sides are equipped at the draw point seat center
It protects thin device to connect with shell by coat, is equipped at Manual press on the right side of the draw point seat, top at the Manual press
It is connected with draw point seat switch, the draw point seat switch is connected with the touch switch being located at needle handle；The steel needle periphery is equipped with steel
Needle outer tube, steel needle outer tube periphery are equipped with casing spring；Steel needle outer tube top is equipped with Needlestick prevention device, described
The pin hole passed through for steel needle is equipped at Needlestick prevention device center, the right end of the Needlestick prevention device is equipped with anti-needle and pierces spring；It is described
Steel needle is surrounded by conduit beyond housing parts, and the lower left side of the conduit is equipped with perfusion tube.
Further, it is formed at the Manual press with draw point seat switch integrated.
Further, the top surface of the steel needle outer tube and the top surface of shell are located at same level.
Further, the anti-needle thorn spring is arranged in needle handle.
Further, it is telescopic membrane structure that the coat, which protects thin device,.
Further, the steel needle is fixed in draw point seat.
The utility model has the beneficial effect that steel needle is fixed at the center of draw point seat compared with prior art, steel
Needle passes through the pin hole on Anti-stabbing device, is equipped at Manual press on the right side of draw point seat, and top is connected with draw point seat switch at pressing,
Draw point seat switch is connected with touch switch, and when using, medical worker's right hand holds needle handle, and thumb is placed on Manual press
Place, in the vein comprising the conduit of steel needle insertion infant, then right hand index finger presses the touch switch on needle handle, touches
The connection of switch and draw point seat switch disconnects, and the casing spring compressed originally springs back, and draw point seat is with being fixed therein
Steel needle at the heart is popped up from conduit, has achieved the effect that the automatic withdraw of the needle, and when steel needle is extracted out from pin hole, anti-needle thorn spring is returned
Bullet makes steel needle and pin hole misplace, it is therefore prevented that steel needle is again introduced into conduit, achievees the effect that anti-needle thorn, if the automatic withdraw of the needle is lost
It loses, medical worker can carry out the withdraw of the needle either manually or by draw point seat is held；Since steel needle is per se with invisible blood, it is
Preventing blood from pollution just devises coat and protects thin device, which uses telescopic membrane structure, do not exit in steel needle
When, in the state tightened, after anti-steel needle exits, deflated state is presented, can effectively prevent blood outflow to cause dirt
Dye, while the structure of steel needle outer tube is three section outer tube shell types, and steel needle is also wrapped up wherein, preventing blood from pollution is equally played
Effect, whole device structure is simple, easy to use, can mitigate many work difficulties for medical worker.
