As shown in Figure 1 and Figure 2, in figure, each label is as follows: 1 shell, 2 triggers, 3 links, 4 needle stands, 5 nook closing members, 6 springs, 7 sealed membranes, 21 trigger projection blocks, 22 trigger fixture blocks, 23 nook closing member gathering sills, 24 second spring fixing groove, 25 nook closing member through holes, 41 first spring fixing groove, 42 needle stand protruding blocks.
According to a kind of insulin syringe of this embodiment of the present utility model, comprise shell 1, nook closing member 5, spring 6, trigger 2, needle stand 4, link 3 and sealed membrane 7.
The connected mode of the present embodiment:
Shell 1 is the tubular structure of a blind end, and nook closing member 5, spring 6, trigger 2, needle stand 4 and link 3 are fixed in shell;
The opening of shell 1 is fixed in one end of link 3, and the other end is fixedly connected with needle stand 4;
One end of trigger 2 connects needle stand 4, and the other end is provided with nook closing member through hole 25;
What nook closing member 5 ran through is fixed on needle stand 4, and make its part be placed in link 3, another part is placed in trigger 2;
Spring 6 is placed between needle stand 4 and trigger 2;
The opening of the fixing also closure 1 of sealed membrane 7.
Concrete, one end of link 3 is fixedly connected with needle stand 4.
Needle stand 4 is connected with one end of trigger 2, and connected mode is: one end that trigger 2 is connected with needle stand 4 is provided with trigger fixture block 22 and has the trigger projection block 21 of slope structure; On needle stand 4, its position be connected with emitter 2 be provided with trigger projection block 21 with the use of needle stand protruding block 42, needle stand protruding block 42 has slope structure equally; Needle stand 4 is placed in trigger fixture block 22 and trigger projection block 21 centre on trigger 2, realizes the connection of trigger 2 and needle stand 4.
The center of needle stand 4 is fixedly connected with nook closing member 5, and nook closing member 5 runs through needle stand 4, and make nook closing member 5 part be placed in link 3, another part is placed in trigger 2; The top center place, one end not connecting needle stand 4 at trigger 2 is provided with nook closing member through hole 25, and nook closing member 5 can be passed through from nook closing member through hole 25; Nook closing member gathering sill 23 is also provided with around the inner nook closing member through hole 25 of trigger 2, free end nook closing member 5 being arranged in trigger 2 inside is placed in nook closing member gathering sill 23, to lead to the traffic direction of nook closing member 5, in the process preventing insulin syringe from using, nook closing member 5 departs from and cannot use.
Spring 6 is arranged between needle stand 4 and trigger 2, and one end that wherein needle stand 4 does not connect link 3 is provided with the first spring fixing groove 41; Trigger 2 is provided with around nook closing member gathering sill 23 the second spring fixing groove 24 be used in combination with the first spring fixing groove 41; Fix spring 6 by the first spring fixing groove 41 and the second spring fixing groove 24, prevent spring 6 from being occurred displacement by the process compressed, and affect the use of insulin syringe.
The two ends of nook closing member 5 all have the structure in sword face, can carry out thrusting in patient body respectively and be connected insulin injection device use.
The opening of the other end connected with outer casing 1 of link 3, the structure that shell 1 is closed for having one end open one end, link 3, needle stand 4, nook closing member 5, trigger 2 and spring 6 is made all to be positioned at shell 1 inner, closed by the opening of sealed membrane 7 by shell 1, make insulin syringe form a closed structure, ensure that insulin syringe can not touch pollutant and make it use before application.
Further, the central shaft of needle stand 4, nook closing member 5 and trigger 2 is located along the same line, and makes insulin syringe there will not be centre-of gravity shift and the unsuccessful situation of injection of insulin in the process of application.
The embody rule step of the present embodiment is:
(1) when needing to carry out the injection of insulin to patient, first the sealed membrane 7 in insulin syringe of the present utility model being removed, exposing and be positioned at link 3 inside shell 1.
(2) one end be connected with shell 1 due to link 3 is opening, therefore, it is possible to see the one end of the nook closing member 5 being positioned at link 3 inside, insulin injection device is connected by link 3, make it thrust to carry out taking of insulin medicament in insulin injection device by the sword face structure of nook closing member 5, and the injection volume of insulin medicament is set.
(3) take off the shell 1 of insulin syringe, make link 3, trigger 2 all exposes in air.
(4) insulin syringe is aimed at the position of needs of patients insulin injection medicine, can make to have the trigger projection block 21 of slope structure by pressing operation and needle stand protruding block 42 causes mutual slip, needle stand protruding block 42 is by the obstruction of trigger projection block 21, make nook closing member 5 by nook closing member through hole 25 and expose outside trigger 2, thus nook closing member 5 to be thrust in patient body and to carry out the injection of insulin.
(5) after having injected, insulin syringe is taken off, because spring 6 when carrying out pressing operation in insulin syringe is compressed, after taking off insulin syringe, spring 6 can automatically reply previous status and make nook closing member 5 again be pulled trigger 2 inside, together discards with shell 1, sealed membrane 7.
The present embodiment prevents insulin syringe from by the method again utilized being: after insulin syringe has been applied, nook closing member 5 is pulled the inside of trigger 2 under the restoring force effect of spring 6, but because needle stand protruding block 42 is by trigger projection block 21, the slope structure of needle stand protruding block 42 and trigger projection block 21 can stop its reinstatement, thus nook closing member 5 also cannot homing be put, the effect reminding staff and patient can be played, prevent it from again utilizing.
A kind of structure of insulin injector of the present embodiment is simple, be convenient to manufacture, and applies conveniently simultaneously.By the effect of spring, nook closing member after application completes can be entered in insulin syringe by the automatic recovery, thus effective protection staff is not stabbed, and prevents cross infection situation by nook closing member.
A kind of insulin syringe of the present utility model has the advantage that structure is simple, be convenient to manufacture, and shell mechanism can effectively prevent nook closing member from being polluted before application, ensures the safety of patient; Insulin syringe can carry out the automatic recovery after being used to complete, and homing cannot put and insulin syringe cannot be recycled due to nook closing member, effectively prevent the problem of secondary application.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
