Abstract
The invention relates to an implicit needle mechanism of an injector. The implicit needle mechanism comprises the injector. One end of the injector is provided with a medicine bottle and a syringe needle. The implicit needle mechanism comprises a syringe needle outer cover, a syringe needle inner cover and springs, wherein the syringe needle outer cover is connected with one end of the injector and the syringe needle arrangement end, the syringe needle inner cover is embedded inside the syringe needle outer cover, and the springs are arranged in the syringe needle inner cover and surround a medicine bottle end cover. The syringe needle inner cover can stretch out and draw back freely to reset relative to the syringe needle outer cover through the springs. A syringe needle outlet hole is formed in the end of the syringe needle inner cover. According to the implicit needle mechanism of the injector, the syringe needle of the injector is hidden inside a space, so that a sense of fear, generated when the syringe needle is used, of patients is effectively avoided, injection accuracy is improved, and meanwhile unnecessary harm brought by exposure of the syringe needle can be avoided as well.
Description
Technical field
The present invention relates to a kind of syringe, specifically disclose a kind of syringe Yin Zhen mechanism.
Background technology
The direct inserting needle of the many employings of existing syringe, syringe needle is outside exposed, easily causes fear when patient uses, and causes mental pressure, thus injection may be caused inaccurate.Simultaneously due to syringe needle outside, without any protector, patient in use, easily causes other unnecessary injuries.
Summary of the invention
The object of the invention is to: provide a kind of structure simple syringe Yin Zhen mechanism for overcoming the above problems, the mental pressure that can effectively avoid patient to produce in use, improve injection accuracy, can avoid leaking outside the unnecessary injury produced because of syringe needle simultaneously.
The technical solution adopted in the present invention is such:
A kind of syringe Yin Zhen mechanism, comprise syringe, described syringe one end is provided with medicine bottle and syringe needle, this mechanism also comprises and arranges with described syringe one end, described syringe needle the syringe needle enclosing cover held and be connected, be nested in the syringe needle inner cap of described syringe needle enclosing cover inside, be arranged in described syringe needle inner cap, around the spring of described bottle end cover; Described syringe needle inner cap relies on described spring, can reset relative to described syringe needle enclosing cover free-extension; Described syringe needle inner cap end is provided with syringe needle portal.
Further, the retract critical distance of described syringe needle enclosing cover inside of described syringe needle inner cap is greater than effective injection length of described syringe needle.
Further, at described spring, the described bottle end cover place of abutting is provided with ring-spring tabletting, described spring one end and described syringe needle inner cap abut against, and the other end and described spring pressuring plate abut against.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:
1, the syringe of this Yin Zhen mechanism is installed, patient in use can't see syringe needle completely, whole inserting needle, injection and withdrawal process all complete in mechanism inside, can greatly reduce the fear brought when patient sees syringe needle, thus advantageously in injection.Simultaneously hidden pin inner cap and enclosing cover coordinate and the travel depth of spring pressuring plate all substantially increases product safety in use.
2, the invention enables syringe needle not expose, in use procedure, can effectively avoid unnecessary injury.
3, from structure, the structure that the present invention adopts hidden pin inner cap to be separated with hidden pin enclosing cover, hidden pin enclosing cover is connected by clamping with between syringe simultaneously, makes Assembly And Disassembly be convenient like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is hidden pin inner cover structure figure of the present invention;
Fig. 3 is hidden pin outer cover structure figure of the present invention;
Fig. 4 is an embodiment of the present invention structure chart.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in figures 1-4, a kind of syringe Yin Zhen mechanism, comprise syringe, described syringe one end is provided with medicine bottle 5 and syringe needle 2, this mechanism also comprises and arranges with described syringe one end, described syringe needle 2 the syringe needle enclosing cover 6 held and be connected, be nested in the syringe needle inner cap 1 of described syringe needle enclosing cover 6 inside, be arranged in described syringe needle inner cap 1, around the spring 3 of described medicine bottle 5 end cap; At described spring 3, the described medicine bottle 5 end cap place of abutting is provided with ring-spring tabletting 4, described spring 3 one end and described syringe needle inner cap 1 abut against, and the other end and described spring pressuring plate 4 abut against; Described syringe needle inner cap 1 relies on described spring 3, can reset relative to described syringe needle enclosing cover 6 free-extension; Described syringe needle 2 is positioned at the space that described syringe needle enclosing cover 6 and described syringe needle inner cap 1 surround, and described syringe needle inner cap 1 end is provided with syringe needle and portals.
The retract critical distance of described syringe needle enclosing cover 6 inside of described syringe needle inner cap 1 is greater than effective injection length of described syringe needle 2, and one can ensure that syringe needle 2 does not expose, and two can ensure effective injection.
Described syringe needle enclosing cover 6 lower end is provided with back-off structure, the bayonet socket matched with described back-off structure is provided with in the inside of described syringe body, make just clamping between described syringe needle enclosing cover 6 and described syringe body, make this syringe Yin Zhen mechanism installing/dismounting convenient, be more conducive to changing medicine bottle.
Described syringe needle enclosing cover 6 lower end inside edge is provided with the fin around its inwall, described syringe body and described syringe needle enclosing cover 6 contact position are provided with the groove matched with described fin, make just clamping between described syringe needle enclosing cover 6 and described syringe body, make this syringe Yin Zhen mechanism installing/dismounting convenient, be more conducive to changing medicine bottle.
In use, hidden pin inner cap 1 and contact skin, then press before syringe, then complete inserting needle action, and syringe needle enclosing cover 6 and syringe needle 2 all can advance in pushing course, syringe needle inner cap 1 can not be able to advance under spring 3 acts on, all the time with contact skin, to be injected complete after, extract syringe needle 2, syringe needle inner cap 1 also can spring 3 act under reset.
Described syringe needle inner cap 1 and described syringe needle enclosing cover 6 all similar round table-like, the bottom size of described syringe needle inner cap 1 is greater than the top size of described syringe needle enclosing cover 6 and is less than the bottom size of described syringe needle enclosing cover 6, make described syringe needle inner cap 1 can embed described syringe needle enclosing cover 6 inside and not skid off, both combine the effective normal injection use ensureing hidden needle injection.
The foregoing is only specific embodiments of the invention, be not limited to the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
