In this case,, therefore can there be situation about decaying, reflects with intensity intensity about equally with irradiation because of the air in the groove 30 owing to echo E reflects by the internal face 30a of groove 30.
Then, the echo E of reflection is received by detector 60 in the groove 30 of conduit 20, these data that receive 64 are handled to the not shown control part output of ultrasonic echo device 58 by going between from detector 60, afterwards, are shown as image on display screen 62.In detail, the image of the remaining needle 10 that on display screen 62, shows, be shown as by the wire of ultrasonic echo device 58 detected grooves 30, can confirm whether its top ends arrives patient 56 blood vessel (vein) from display screen 62 along the length scale of axis direction.
Its result clearly is presented on the display screen 62 of ultrasonic echo device 58 as image near being provided with the top ends of conduit 20 of groove 30, can confirm to comprise the position of the remaining needle 10 of conduit 20 accurately.In other words, the Visual Confirmation of remaining needle 10 is further improved.
Then, one side doctors etc. confirm display screen 62, Yi Bian mobile remaining needle 10 and detector 60, thus the blood vessel of puncture needle 18 to patient 56 imported.At this moment, on one side suitably the push rod 38 of dilazep syringe 16 remaining needle 10 is advanced on one side.
Advance blood vessel in case this puncture needle 18 punctures exactly, blood produces backflow by the connector 42 of syringe 16 to syringe body 36 importings.
Like this, after having confirmed that puncture needle 18 is punctured to blood vessel, conduit 20 is stayed and puncture needle 18 and syringe 16 is unloaded, insert not shown leading line in the blood vessel by conduit 20 after, remove conduit 20.Next, along leading line, not shown inlying catheter (central venous catheter) is retained in the blood vessel.Then, not shown tube for transfusion is connected with inlying catheter and in blood vessel, supplies with nutrient, medicinal liquid etc.
As above, in the remaining needle 10 of the 1st example, have conduit 20 and insert the puncture needle 18 that leads in the inside of conduit 20, the interior pipe 22 that conduit 20 has outer pin body 26 and is arranged on interior all sides of outer pin body 26, outer pin body 26 has groove 30, this groove 30 is arranged near the top ends the inner peripheral surface, and caves in into the cross section to outer circumferential side and be convex.Owing to make such structure, therefore when remaining needle 10 is punctured to patient 56, the echo E that irradiates from ultrasonic echo device 58 reliably and is suitably reflected groove 30 and detects.
Its result can reliably and accurately confirm the remaining needle 10 after patient 56 puncture by ultrasonic echo device 58, while doctor etc.s can confirm that the position of remaining needle 10 carries out safety and reliable the operation.
In addition, because groove 30 forms the cross section and is semicircle shape, therefore even when remaining needle 10 during, also can make detector 60 lateral reflections of the echo E of ultrasonic echo device 58 by the internal face 30a of groove 30 towards the direction of illumination that becomes echo E with respect to puncture angle θ (with reference to Fig. 6) variation of patient 56 skin surface 56a.In other words, can irrespectively make echo E with the puncture angle of remaining needle 10, and confirm the position of remaining needle 10 to detector 60 lateral reflections.
And, even when in patient 56 body, only having kept somewhere the conduit 20 of remaining needle 10, also can be reliably and confirm the position of conduit 20 accurately by being arranged on groove 30 on the conduit 20, therefore, even if under the conduit 20 wrong situations about moving of for example keeping somewhere, also can confirm that its position makes it revert to desired locations by ultrasonic echo device 58.
Again, outside making pin body 26 and interior pipe 22 in conjunction with and when forming remaining needle 10,, therefore on top ends, also can make echo E carry out the detection of the apical position of remaining needle 10 to detector 60 lateral reflections because its top ends forms the taper of undergauge gradually.That is,, on the top ends of conduit 20, also can make the echo E reflection of ultrasonic echo device 58, therefore in the larger context near the top ends of Visual Confirmation conduit 20 except being arranged on the groove 30 on the conduit 20.
Again,, and, therefore can not be exposed to the outside of remaining needle 10 by 22 coverings of interior pipe owing to groove 30 is arranged on the inner peripheral surface of conduit 20, and also can be outstanding to the outside.Therefore, compare, remaining needle 10 can not become resistance when patient 56 punctures, also can alleviate load for patient 56 with for example situation at the concavo-convex slot part of arranged outside of remaining needle 10.
On the other hand, in the remaining needle 10 of the 1st above-mentioned example, the situation that the gap 32 of predetermined distance is set between the outer peripheral face to the inner peripheral surface of pin body 26 outside and interior pipe 22 is illustrated, but remaining needle 100 as shown in Figure 8 also can not be provided with gap 32 and the inner peripheral surface of conduit (outer pin) 102 and the outer peripheral face of interior pipe 104 are closely contacted.Thus, the periphery footpath of conduit 102 can be set lessly, thereby the minor diameterization of the remaining needle 100 of conduit 102 can be realized comprising.
Next, the remaining needle 120 of expression the 2nd example in Fig. 9.In addition, for the member element annotation identical reference marks identical, and omit its detailed description with the remaining needle 10 of above-mentioned the 1st example.
In the remaining needle 120 of this 2nd example, between conduit (outer pin) 120 and puncture needle (interior pin) 18, interior pipe is not set, be arranged to relatively and will be arranged on groove 30 on the inner peripheral surface of conduit 122, be different from the remaining needle 10 of the 1st example in this with the outer peripheral face of puncture needle 18.
This remaining needle 120 is inserted in the inside of the outer pin body 26 that constitutes conduit 122 and to be connected with puncture needle 18, the interior Zhou Jing of outer pin body 26 be set at the periphery footpath of puncture needle 18 about equally.And, be formed on the outer peripheral face that groove 30 on the inner peripheral surface of conduit 122 is punctured pin 18 and stop up.Outer peripheral face by this puncture needle 18 forms spatial portion S in groove 30.
Like this, in the remaining needle 120 of the 2nd example, have conduit 122, insert the puncture needle 18 that leads in conduit 122 inside, conduit 122 is made of outer pin body 26, therefore compare with the situation of pipe in being provided with in interior week of pin body 26 outside, part number and manufacturing cost can be cut down, and also the assembling procedure number can be cut down.
In addition, remaining needle of the present utility model and manufacture method thereof are not limited to above-mentioned example, do not break away from main idea of the present utility model and adopt various structures also to be fine certainly.
