The specific embodiment
Fig. 1 is the structure chart of disposable blood-letting puncture pin of the present utility model; As shown in Figure 1, disposable blood-letting puncture pin of the present utility model comprises: nook closing member 1, one end has needle point 1a; The needle body 2 is sleeved on the other end of nook closing member 1, and an end of the needle body has the opening 2a that stretches out for nook closing member; And pin trocar sheath 3, be sleeved on the needle body 2 outsides, have the space of accommodating needle point, a pin trocar sheath end corresponding with needle point is sealing, other end opening; Wherein, nook closing member 1 is hollow, and the top end face of needle point 1a is the inclined-plane, can alleviate patient's pain, and acupuncture blood-letting puncture therapeutic effect is good.
Particularly, as shown in Figure 1, nook closing member 1 is made by alloy material, nook closing member 1 inside is hollow, the top end face of one end of nook closing member 1 is the inclined-plane, form needle point 1a, the other end overcoat of nook closing member 1 is established locating piece 10, and it is the polygonal rotational positioning 10b of section greater than the 10a of running fix section and the cross section of nook closing member external diameter that locating piece 10 has diameter.The 10a of running fix section shown in Fig. 1 and the 10b of rotational positioning section form one, are made by macromolecular material; The 10b of rotational positioning section also can divide with the 10a of running fix section and is arranged, the 10a of running fix section can be fixed on any position on the nook closing member 1, but must guarantee that the running fix 10a of section and needle point 1a are at a distance of certain distance, so that needle point 1a can stretch out from opening 2a.To the needs of nook closing member length, preferably, the 10a of running fix section is arranged on the position of closing on nook closing member 1 other end, thereby so that nook closing member 1 stretches out the needs that the length of opening 2a can satisfy blood-letting puncture when satisfying blood-letting puncture.
The vertical sectional shape of the rotational positioning 10b of section of the present utility model can polygon, also can be ellipse, or other arbitrary shape, but can not be circle.The end of the other end of the corresponding nook closing member 1 of the 10b of rotational positioning section.
The needle body 2 of the present utility model is made for macromolecular material, and the needle body 2 comprises needle body leading portion 20 and needle body back segment 21; One end of needle body leading portion 20 is connected with the threaded one end of needle body back segment 21, and the other end of needle body leading portion 20 is provided with opening 2a, the other end sealing of needle body back segment 21; The diameter of opening 2a is greater than the external diameter of nook closing member 1 external diameter less than the 10a of running fix section.The inside of the blind end of needle body back segment 21 is provided with the groove 21a that matches with the 10b of rotational positioning section.
When nook closing member is installed, at first needle point 1a is inserted the inner chamber of needle body leading portion 20, and so that needle point 1a stretches out needle body leading portion 20 from opening 2a, continue to promote nook closing member 1, until the 10a of running fix section contacts with opening 2a, because therefore the diameter of opening 2a can't continue to promote nook closing member greater than the external diameter of nook closing member 1 external diameter less than the 10a of running fix section this moment again.
Then, the 10b of rotational positioning section that is fixed on nook closing member 1 end is alignd with groove 21a, needle body back segment 21 is threaded with needle body leading portion 20.Along with tightening gradually of needle body back segment 21 and needle body leading portion 20, the end of nook closing member 1 inserts in the needle body back segment 21 gradually until cooperate fully with groove 21a.During design, should be so that needle body back segment 21 when tightening with needle body leading portion 20, the 10b of rotational positioning section of nook closing member 1 end just is resisted against in the groove 21a, under the effect of needle body back segment 21 and the 10a of running fix section, nook closing member 1 can't move left and right in the needle body 2, thus when having guaranteed blood-letting puncture nook closing member 1 to stretch out the length of the needle body 2 constant; Because the vertical sectional shape of the 10b of rotational positioning section be circular, so the 10b of rotational positioning section is resisted against groove 21a and can't arbitrarily rotates when interior, thereby nook closing member can arbitrarily not rotate when having guaranteed blood-letting puncture, so just nook closing member 1 is positioned in the needle body 2.
Controlling conveniently during for the attractive in appearance of the needle body 2 and use, one end that needle body leading portion 20 can be closed on opening 2a is designed to the diminishing taper shape of diameter, in order to cooperate the shape of needle body leading portion 20, an end that the 10a of running fix section can be closed on opening 2a also is designed to the diminishing taper shape of diameter (as shown in Figure 1) like this.
Again as shown in Figure 1, be provided with the protruding 21b of a circle on the outer wall of needle body back segment 21, pin trocar sheath 3 one end openings, other end sealing is provided with the draw-in groove 30 that is complementary with protruding 21b on the inwall of pin trocar sheath 3.When nook closing member 1 is installed in the needle body 2 interior after, pin trocar sheath 3 is sleeved on the part that nook closing member 1 stretches out the needle body 2, and so that protruding 21b snap in the draw-in groove 30, thereby pin trocar sheath 3 is fixed on the needle body 2, and so that nook closing member 1 be enclosed in the inner chamber of pin trocar sheath 3, thereby avoid nook closing member to be polluted.During design should so that this moment needle point 1a and pin trocar sheath 3 inwall at intervals, thereby damage needle point 1a.
For carrying of convenient venesection needle of the present utility model, can be provided with handle 31 at pin trocar sheath 3.
During use, only need to firmly pull out pin trocar sheath 3 and just can carry out the blood-letting puncture operation.
After finishing using, turn on needle body leading portion 20 and needle body back segment 21, nook closing member 1 is taken out from needle body leading portion 20, the nook closing member that more renews carries out the installation of nook closing member according to above-mentioned steps, so that the needs of blood-letting puncture next time.
Although above-mentioned this utility model is described in detail; but this utility model is not limited to this; those skilled in the art can make amendment according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
