Description

Diacan

Technical field

This utility model relates to field of medical products, in particular to diacan.

Background technology

In clinical treatment, diacan is widely used in hemodialysis.But, current diacan can be retained in patient body in patient treatment process always, and patient moves a little and just may puncture blood vessel, causes blood extravasation, and in its process of extracting, also can scratch internal fistula and blood vessel after treatment completes, use safe and reliable not.

Utility model content

The purpose of this utility model is to provide diacan, in use easily damages internal fistula and blood vessel, safe and reliable not problem to solve existing diacan.

This utility model is achieved in that

This diacan comprises puncture draw point, puncture draw point appearance surface cover has the trocar, trocar rear end is connected with extension tube, one end that the trocar connects described extension tube is provided with fixation clamp, extension tube is connected with calparine cap, calparine cap is connected with screw-cap, and screw-cap is fixedly connected with described puncture draw point.When use, be first fixed folder, make its gripping sleeve bobbin thrust patient vessel together with puncture draw point, then unclamp fixation clamp, utilize fixation clamp that the trocar is pushed in blood vessel, then rotating screw cap, the draw point that will puncture is extracted out, then extension tube is communicated with external conduit, starts dialysis treatment.

Further, on fixation clamp, be provided with stitching pin hole.As needs indwelling trocar can after puncturing successfully, will puncture draw point extract out, the trocar can by sew up pin hole be sutured on patient skin, fix with the reservation that facilitates the trocar.

Further, the trocar and extension tube interconnect by welding.The trocar and extension tube are made by flexiplast, and welding can make that both are stable links together simply.

Further, diacan comprises screw-button, and extension tube is communicated with external conduit by screw-button.It is stable that screw-button can make extension tube and external conduit be communicated with, difficult drop-off.

Further, in extension tube, be provided with hemostatic clamp.After puncture draw point is extracted out, hemostatic clamp is clamped extension tube, can outflow by anti-Hemostatic Oral Liquid, then takes off calparine cap, and external conduit is communicated with extension tube.

Further, the diameter of extension tube is the trocar 3 times, to extend and flow process and pressure when buffering blood enters external conduit, reduce the risk that security incident occurs.

Further, diacan also comprises hard plastic packing tube, is provided with the screw lid mating with screw-cap on hard plastic packing tube.Puncture draw point uses after rear extraction, by screw-cap and screw lid fastening, then puts in hard plastic packing tube and discards, and prevents that clinical waste from polluting.Simultaneously, because puncture draw point is fixed on screw-cap, therefore can not pack in-pipe in hard plastic, expose after can avoiding puncturing hard plastic packing tube, security incident occurs.

This diacan adopts the structure that the trocar is set at puncture draw point outer surface, thrusts after patient vessel, and puncture draw point can be extracted, and has effectively reduced the injury to patient's internal fistula and blood vessel in therapeutic process, and medical worker operates also very convenient simple.

Brief description of the drawings

Fig. 1 shows the structure of the diacan that this utility model embodiment provides.

Detailed description of the invention

Also by reference to the accompanying drawings this utility model is described in further detail below by specific embodiment.

Consult Fig. 1, this diacan comprises puncture draw point 800, puncture draw point 800 appearance surface covers have the trocar 100, the trocar 100 rear ends are connected with extension tube 300, one end that the trocar 100 connects extension tube 300 is provided with fixation clamp 200, extension tube 300 is connected with calparine cap 500, and calparine cap 500 is connected with screw-cap 600, and screw-cap 600 is fixedly connected with puncture draw point 800.When use, first be fixed folder 200, make its gripping sleeve bobbin 100 thrust patient vessel together with puncture draw point 800, then unclamp fixation clamp 200, utilize fixation clamp 200 that the trocar 100 is pushed in blood vessel, then rotating screw cap 600, the draw point 800 that will puncture is extracted out, then extension tube 300 is communicated with external conduit, starts dialysis treatment.

On fixation clamp 200, be provided with and sew up pin hole 250.As needs indwelling trocar 100 draw point 800 that can will puncture after puncturing is successfully extracted out, the trocar 100 can be sutured on patient skin by sewing up pin hole 250, fixes with the reservation that facilitates the trocar 100.

The trocar 100 and extension tube 300 interconnect by welding.The trocar 100 and extension tube 300 are made by flexiplast, and welding can make that both are stable links together simply.

Diacan comprises screw-button 400, and extension tube 300 is communicated with external conduit by screw-button 400.It is stable that screw-button 400 can make extension tube 300 and external conduit be communicated with, difficult drop-off.

In extension tube 300, be provided with hemostatic clamp 350.After puncture draw point 800 is extracted out, hemostatic clamp 350 is clamped extension tube 300, can outflow by anti-Hemostatic Oral Liquid, then takes off calparine cap 500, and external conduit is communicated with extension tube 300.

The diameter of extension tube 300 is 3 times of the trocar 100, to extend and flow process and the pressure of buffering blood while entering external conduit, reduces the risk that security incident occurs.

Diacan also comprises hard plastic packing tube 700, is provided with the screw lid 750 mating with screw-cap 600 on hard plastic packing tube 700.Puncture draw point uses after extraction, by screw-cap 600 and screw lid 750 fastenings, then puts into 700 li of hard plastic packing tubes discarded, prevents that clinical waste from polluting.Simultaneously because puncture draw point 800 is fixed on screw-cap 600, therefore can be in the interior movement of hard plastic packing tube 700, expose after can avoiding puncturing hard plastic packing tube 700, there is security incident.

This diacan adopts the structure that the trocar 100 is set at puncture draw point 800 outer surfaces, thrust after patient vessel, puncture draw point 800 can be extracted, and has effectively reduced the injury to patient's internal fistula and blood vessel in therapeutic process, and medical worker operates also very convenient simple.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
