Abstract
The invention discloses an intravenous infusion needle, and relates to an infusion apparatus in medical supplies. The intravenous infusion needle comprises an infusion tube, a drip cup, a flow regulator, a puncture needle, an exhaust pipe, a needle base and an injection needle, wherein the drip cup and the flow regulator are arranged on the infusion tube, the puncture needle and the exhaust pipe are arranged at one end of the infusion tube, the needle base and the injection needle are arranged at the other end of the infusion tube, and a needle handle is arranged on the needle base. A sleeve pipe used for placing of the needle base and the injection needle is arranged on the infusion tube at the end where the puncture needle is placed, one end of the sleeve pipe is sealed, and the other end of the sleeve pipe is opened. The side face of the sleeve pipe is connected with the infusion tube. A cutting seam, a first clamping seam and a second clamping seam are vertically formed in the side face of the sleeve pipe. The lower end of the cutting seam extends to the opened end of the sleeve pipe, the upper end of the cutting seam is communicated with the horizontally-formed first clamping seam, and the lower end of the first clamping seam is communicated with the second clamping seam to constitute a clamping groove used for clamping the needle handle. By means of the intravenous infusion needle, a syringe needle of the infusion needle can be effectively protected, residual liquid medicine in the infusion apparatus can be prevented from flowing into the environment, so that pollution is avoided, and the intravenous infusion needle can be used conveniently.
Description
Technical field
The present invention relates to the transfusion device in medical supplies, be specially venoclysis needle.
Background technology
At present; disposable venous infusion needle is generally to protect syringe needle with protection tube on syringe needle in the time dispatching from the factory; how protection tube does not re-use with rear at transfusion needle; complete after transfusion patient; medical personnel often directly put into transfusion needle sharp weapon box or injection needle are temporarily fixed on the rubber stopper of infusion bottle; infusion needle is exposed to outside the stabbing of medical personnel of easily causing, and the danger of infecting easily occurs.Existing employing sheathed sleeve pipe on the tube for transfusion of transfusion needle one end is protected entry needle; because sleeve pipe is both ends open; the residual medicinal liquid of being totally lost after liquid in entry needle still can flow out and to environment from syringe needle; complete after transfusion in addition; medical personnel need bimanualness that entry needle is enclosed within sleeve pipe, and in case of emergency operation has inconvenience more.
Summary of the invention
Object of the present invention is just to provide a kind of can effectively protection and venoclysis needle easy to use the syringe needle of transfusion needle.
To achieve these goals, technical scheme of the present invention is: a kind of venoclysis needle, comprise tube for transfusion, be arranged on droplet kettle and flow regulator on tube for transfusion, be arranged on puncture needle and the exhaustor of tube for transfusion one end, be arranged on needle stand and the entry needle of the tube for transfusion other end, needle stand is provided with needle handle, the tube for transfusion of puncture needle place end is provided with one for placing the sleeve pipe of needle stand and entry needle, one end sealing of sleeve pipe, other end opening, the side of sleeve pipe is connected with tube for transfusion, the side of described sleeve pipe is provided with the joint-cutting of vertical setting, the first card seam and the second card seam, the lower end of joint-cutting extends to the opening of sleeve pipe, the first card seam that the upper end of joint-cutting is offered with level communicates, the lower end of the first card seam communicates and forms one for blocking the draw-in groove of establishing needle handle with the second card seam.
The upper surface of described the first card seam is provided with for coordinating the elastic projection with clamping needle handle with the second card seam, and the bottom of elastic projection is arc shape.
The sealed end of described sleeve pipe is provided with medical cotton pad.
Beneficial effect: the present invention arranges sleeve pipe in the tube for transfusion one end at puncture needle place, can be clamped in the entry needle of being totally lost after liquid in sleeve pipe, and syringe needle is played a protective role, and prevents to stab accident.Thereby the sealed end of sleeve pipe inner top arranges medical cotton pad can be absorbed medicinal liquid residual in tube for transfusion, prevent that medicinal liquid from flowing into environment.In addition, medical personnel's one hand can be sent entry needle into sleeve pipe and be fixed, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of sleeve pipe of the present invention.
In figure, be labeled as: 1, tube for transfusion, 2, drip kettle, 3, flow regulator, 4, puncture needle, 5, exhaustor, 6, needle stand, 7, entry needle, 8, needle handle, 9, sleeve pipe, 10, joint-cutting, 11, the first card seam, 12, the second card seam, 13, elastic projection, 14, medical cotton pad.
The specific embodiment
As depicted in figs. 1 and 2, a kind of venoclysis needle, comprise tube for transfusion 1, be arranged on droplet kettle 2 and flow regulator 3 on tube for transfusion 1, be arranged on puncture needle 4 and the exhaustor 5 of tube for transfusion 1 one end, be arranged on needle stand 6 and the entry needle 7 of tube for transfusion 1 other end, needle stand 6 is provided with needle handle 8, the tube for transfusion 1 of puncture needle 4 place ends is provided with one for placing the sleeve pipe 9 of needle stand 6 and entry needle 7, one end sealing of sleeve pipe 9, other end opening, the side of sleeve pipe 9 is connected with tube for transfusion 1, the side of described sleeve pipe 9 is provided with the joint-cutting 10 of vertical setting, the first card seam 11 and the second card seam 12, the lower end of joint-cutting 10 extends to the opening of sleeve pipe 9, the first card seam 11 that the upper end of joint-cutting 10 is offered with level communicates, the lower end of the first card seam 11 communicates and forms one for blocking the draw-in groove of establishing needle handle 8 with the second card seam 12.Wherein, the length of described sleeve pipe 9 upper end to the first card seams 11 is greater than the length after needle stand 6 is connected with entry needle 7, the width of described joint-cutting 10 is greater than the thickness of needle handle 8, the width of the first card seam 11 is greater than longitudinal width of needle handle 8, the width of the second card seam 12 and the consistency of thickness of needle handle 8, thus can guarantee that needle handle 8 can finally be stuck in the second card seam 12.
The upper surface of described the first card seam 11 is provided with for coordinating to clamp the elastic projection 13 of needle handle 8 with the second card seam 12, and the bottom of elastic projection 13 is arc shape.
The sealed end of described sleeve pipe 9 is provided with medical cotton pad 14, can absorb the residual medicinal liquid of tube for transfusion, prevents that medicinal liquid from flowing into environment.
When extracting from medical personnel entry needle 7, can singlehanded hold needle handle 8 sends into entry needle 7 in sleeve pipe 9 from the opening of sleeve pipe 9, sleeve pipe 9 is arranged on the tube for transfusion one end at puncture needle 4 places, convenient operation, needle handle 8 is finally stuck in the second card seam 12, and elastic projection 13 can further coordinate and clamp needle handle 8 with the second card seam 12.Longitudinal width of existing needle handle 8 generally broadens gradually from itself and needle stand 6 junctions to its elongated end, therefore can make needle handle 8 by the first card seam 11 and finally be stuck in the second card seam 12.The internal diameter assurance of sleeve pipe 9 is connected the tube for transfusion 1 of one end and can enters smoothly with needle stand 6.
