Abstract
The invention discloses an indwelling needle. The indwelling needle comprises an indwelling syringe, a switch, a temperature detector and a temperature displayer, wherein the front end of the indwelling syringe is closed, a liquid outlet is formed in the side wall of the indwelling syringe, and an opening is formed in the rear end of the indwelling syringe; the switch is of a tubular structure and is arranged in the indwelling syringe in a sliding mode, the side wall of the switch makes contact with the inner wall of the indwelling syringe in a sealed mode, the switch slides forwards to seal the liquid outlet and the front end of the indwelling syringe, and the switch slides backward to open the liquid outlet; the temperature detector is disposed on the outer side of the front end of the switch, and a signal line of the temperature detector extends along the inside of the switch and extends out from the rear end of the switch; the temperature displayer is connected with the signal line. When infusion is not conducted, the switch is pushed forward, so that the side wall of the switch seals the liquid outlet, blood can not enter the indwelling syringe, and blood embolism does not happen. Besides, when infusion is needed, the switch is drawn outward, part of blood enters the indwelling syringe, and the temperature detector at the front end of the switch can detect blood temperature.

Indwelling needle tubing, its front end is opened wide, and the side wall of described indwelling needle tubing offers fluid hole, after described indwelling needle tubing
End has opening；
Switch, it is tubular structure, is slidably disposed in described indwelling needle tubing, and the rear end of described switch is from described
The opening of indwelling needle tubing stretches out, and the side wall of described switch is in sealing contact with described indwelling needle interior wall, described switch forward slip
To close the front end of described fluid hole and described indwelling needle tubing, described switch slides backward to open described fluid hole and described to stay
Put the front end of needle tubing；
Temperature detector, it is arranged at the front end outer side of described switch, and the holding wire of described temperature detector is along stating out
The inside closed extends, and extends out from the rear end of described switch；
Temperature indicator, it connects to described holding wire.
Preferably, in described remaining needle, the rear portion of described indwelling needle tubing is provided with out liquid joint, described go out liquid joint
Connect with woven hose.
Preferably, in described remaining needle, described fluid hole is located at the front position of described indwelling needle tubing.
Preferably, in described remaining needle, the final position of described switch forward slip is：Make the front end of described switch
Compete with each other with the front end of described indwelling needle tubing.
Preferably, in described remaining needle, the rear end of described switch is connected with a Handheld Division.
Preferably, in described remaining needle, described switch includes the tubular body being made of plastics and is arranged on institute
State the rubber stopper of tubular body front end outer side, the centre of described rubber stopper offers through wires hole, described holding wire passes through described wearing
String holes enters to the inside of described switch, and is in sealing contact between described holding wire and described through wires hole.
Remaining needle of the present invention provides a switch, when not infusing, will switch and promote forward, and make switch-side wall
Seal fluid hole and the front end of indwelling needle tubing, blood can not enter the inside of indwelling needle tubing, will not find Blood occlusion；In addition,
When needing transfusion, outwards twitch switch, blood can be partially into indwelling needle tubing, positioned at the temperature detection of switch front end
Device then can detect blood heat.
Brief description
Fig. 1 is structural representation of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification literary composition
Word can be implemented according to this.
As shown in figure 1, the present invention provides a kind of remaining needle, including：Indwelling needle tubing 2, its front end is opened wide, described indwelling needle tubing
Fluid hole 3 is offered on 2 side wall, the rear end 7 of described indwelling needle tubing has opening；Switch 1, it is tubular structure, slidably
Be arranged in described indwelling needle tubing, and the rear end of described switch is stretched out from the opening of described indwelling needle tubing, the side of described switch
Wall is in sealing contact with described indwelling needle interior wall, and described switch forward slip is to close described fluid hole and described indwelling needle tubing
Front end, described switch slides backward to open the front end of described fluid hole and described indwelling needle tubing；Temperature detector 4, its setting
In the front end outer side of described switch, the holding wire 6 of described temperature detector 4 extends along the inside stating switch, and opens from described
The rear end closed extends out；Temperature indicator 11, it connects to described holding wire.
During use, when normally using indwelling battle array, switch is removed backward from indwelling needle tubing, before making fluid hole and indwelling needle tubing
End is opened；It is totally lost liquid, then will switch and promote forward, make switch close the front end of fluid hole and indwelling needle tubing, so that blood is not
Can flow back in indwelling needle tubing, prevent blood back.
In addition, the present invention is provided with a temperature detector in the front portion of switch, when switch is to recession, a small amount of blood can
