Abstract
The utility model provides a remaining needle, it includes: catheter seat, isolating plug, catheter and needle assembly; one end of the catheter seat is connected with the catheter through a non-magnetic rivet, the isolating plug is positioned in the catheter seat, the needle assembly comprises a steel needle and a needle seat, one end of the steel needle penetrates through the isolating plug and extends into the catheter, the other end of the steel needle is fixed on the needle seat, and the needle seat is fixed at the other end of the catheter seat. The utility model discloses an it adopts non-magnetic rivet as the part of connecting catheter and catheter seat to keep somewhere the needle, so, when the patient carries out the nuclear magnetic resonance inspection, the rivet of keeping somewhere in the needle can not exert an influence to nuclear magnetic resonance's result to, needn't pull out and keep somewhere the needle, avoided the waste of keeping somewhere the needle, simultaneously, the misery of puncture and the work load that has reduced medical personnel when having alleviateed patient's infusion.
Description
Technical field
This utility model relates to a kind of remaining needle, particularly relates to a kind of remaining needle of exempting to extract when carrying out nuclear magnetic resonance, NMR.
Background technology
Remaining needle is also known as venous catheter needle, and its main building block comprises the flexible pipe/sleeve pipe that can be retained in endovascular softness, and stainless guiding puncture nook closing member.During use, flexible pipe is punctured into Ink vessel transfusing together with nook closing member, when after the whole intravasation of flexible pipe, withdraw out nook closing member, only the flexible pipe of softness be retained in Ink vessel transfusing thus carry out infusion treatment.
But, generally include rivet in existing remaining needle, so, when patient carries out nuclear magnetic resonance, NMR, remaining needle must be pulled out, with the check result preventing rivet from affecting nuclear magnetic resonance, NMR.Because remaining needle is disposable product, pulls out remaining needle and then cannot continue to use, cause the waste of remaining needle.
Therefore, for the problems referred to above, be necessary to propose further solution.
Utility model content
The purpose of this utility model is to provide a kind of remaining needle, to overcome the deficiencies in the prior art.
For realizing above-mentioned utility model object, of the present utility modelly provide a kind of remaining needle, it comprises: catheter block, batching pig, conduit, needle assembly;
Described catheter block one end is connected with described conduit by non magnetic rivet, described batching pig is arranged in described catheter block, described needle assembly comprises draw point and needle stand, described draw point one end is passed described batching pig and is extend in described conduit, the other end is fixed on described needle stand, and described needle stand is fixed on the other end of described catheter block.
As the improvement of remaining needle of the present utility model, described non magnetic rivet is plastics.
As the improvement of remaining needle of the present utility model, described non magnetic rivet is titanium, titanium alloy, aluminum or copper.
As the improvement of remaining needle of the present utility model, described remaining needle also comprises flexible pipe and joint, and described flexible pipe one end is connected with described catheter block, and the other end is connected with described joint.
As the improvement of remaining needle of the present utility model, described flexible pipe is also provided with flow stopping device.
As the improvement of remaining needle of the present utility model, described joint is positive pressure connector, needleless joint, color threeway, color two are led to.
As the improvement of remaining needle of the present utility model, described remaining needle also comprises sheath, and described sheath is set on described catheter block, and described draw point and conduit are arranged in described sheath.
Compared with prior art, the beneficial effects of the utility model are: remaining needle of the present utility model adopts nonmagnetic rivet as the parts of connecting duct and catheter block, so, when patient carries out nuclear magnetic resonance check, the rivet in remaining needle can not have an impact to the result of nuclear magnetic resonance, NMR, thus, remaining needle need not be pulled out, avoid the waste of remaining needle, meanwhile, the misery punctured when alleviating patient infusion and decrease the workload of medical personnel.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in this utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of remaining needle one detailed description of the invention of the present utility model.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, this utility model is described in detail; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection domain of the present utility model.
As shown in Figure 1, remaining needle of the present utility model comprises: catheter block 10, batching pig 20, conduit 30, needle assembly.
Described catheter block 10 one end is connected with described conduit 30 by non magnetic rivet 11, and wherein, described non magnetic rivet 11 can be plastics, and can be also nonmagnetic metal, such as titanium, titanium alloy, aluminum or copper etc. can not cause the metal of magnetic induction.Described batching pig is arranged in described catheter block 10.So, when patient carries out nuclear magnetic resonance, NMR, the rivet 11 in remaining needle can not have an impact to the result of nuclear magnetic resonance, NMR, thus, need not remaining needle be pulled out, avoid the waste of remaining needle.
Described needle assembly comprises draw point 41 and needle stand 42, and described draw point 41 one end is passed described batching pig 20 and extend in described conduit 30, and the other end is fixed on described needle stand 42, and described needle stand 42 is fixed on the other end of described catheter block 10.And described needle stand 42 can be extracted, draw point 41 and described catheter block 10 can be driven to be separated.
In addition, described remaining needle also comprises flexible pipe 50 and joint 60, and described flexible pipe 50 one end is connected with described catheter block 10, and the other end is connected with described joint 60.Medicinal liquid can be input in catheter block 10 by described joint 60, and be undertaken being input in patient body by conduit 30.In addition, described flexible pipe 50 is also provided with flow stopping device 70, it is for controlling the flow of infusing.Described joint 60 can be positive pressure connector, needleless joint, color threeway, color two are led to.
