In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also Other attached drawings can be obtained according to the attached drawing of offer.

Fig. 1 and Fig. 2 is the overall structure diagram of infusion device disclosed in the utility model embodiment.

Specific embodiment

In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality The attached drawing in example is applied, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described implementation Example is merely a part but not all of the embodiments of the present application.

Based on the embodiment in the application, those of ordinary skill in the art are obtained without making creative work The every other embodiment obtained, shall fall within the protection scope of the present application.

In the description of the present invention, it should be understood that the side of the instructions such as term " upper end ", " lower end ", " outer wall " Position or positional relationship are to be based on the orientation or positional relationship shown in the drawings, and are merely for convenience of description the utility model and simplification is retouched It states, rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, Therefore it should not be understood as limiting the present invention.

Referring to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 provides a kind of specific embodiment of infusion device of the utility model, Fig. 1 and figure 2 be the overall structure diagram of infusion device disclosed in the utility model embodiment.Wherein, Fig. 1 is elastic clamping block expansion Status diagram, Fig. 2 are elastic clamping block compressive state schematic diagram.

As depicted in figs. 1 and 2, the infusion device provided by the utility model can be stuck in infusion bottle by syringe needle in infusion It is interior, it effectively prevent syringe needle to fall off out of infusion bottle.

The infusion device provided by the utility model includes conduit 1, syringe needle 2, the first bayonet 3, the second bayonet 4, guide groove 5, Conducting bar 6, propeller 7, elastic clamping block 8

In the present solution, 1 upper end of conduit is communicated with syringe needle 2, syringe needle 2 is for being connected to external infusion bottle and conduit 1, thus by outer Medical fluid in portion's infusion bottle is directed into conduit 1.

2 outer wall upper end of syringe needle is provided with the first bayonet 3, and the 2 outer wall lower end of syringe needle is provided with the second bayonet 4, the needle Guide groove 5 and the guide groove 5 that first 2 interior is provided with axially disposed connection setting are in first bayonet 3 and described the Between two bayonets 4.

Slideable in guide groove 5 to be equipped with conducting bar 6,6 lower end of conducting bar is connected with propeller 7 and 7, the propeller In in second bayonet 4,6 upper end of conducting bar is connected with elastic clamping block 8 and the elastic clamping block 8 is located at described first In bayonet 3.

In the present solution, conducting bar 6 is for connecting elastic clamping block 8 and propeller 7, propeller 7 is for facilitating control conducting bar 6 to exist Sliding in guide groove 5, so control elastic clamping block 8 position, make elastic clamping block 8 in the first bayonet 3 in guide groove 5 into Line position sets alternating.

Specifically, when the propeller 7 pushes the conducting bar 6 to rise to specified position along the guide groove 5, the elasticity Compact heap 8 enters first bayonet 3 and is in expansion state.At this point, the elastic clamping block 8 of expansion state can be pressed on it is defeated The inner wall of liquid bottle, so that syringe needle 2 is whole stuck in infusion bottle.

When the propeller 7 pushes the conducting bar 6 to drop to specified position along the guide groove 5, the elastic clamping block 5 It hides in the guide groove 5 and in compressive state.At this point, the infusion device just becomes conventional infusion device, syringe needle 2 at this time It can easily be extracted out from infusion bottle, can very easily carry out the replacement of infusion bottle.

Generally speaking, the infusion device provided by the utility model is designed by cleverly structure, when needing to be infused, by this The syringe needle 2 of infusion device injects infusion bottle, and adjustment propeller 7 controls conducting bar 6 and slides, and conducting bar 6 is compressed with regard to energy band dynamic elasticity in turn Block 8 is mobile, and when elastic clamping block 8 is moved in the first bayonet 3, elastic clamping block 8 will be expanded to be tightly pressed against infusion On the inner wall of bottle bottleneck, deviate from from infusion bottle to can effectively prevent syringe needle 2.When needing to change liquid, then adjust under propeller 7 It draws, elastic clamping block 8 is dragged into guide groove 5 and is hidden, to release the lock state of syringe needle 1, syringe needle 1 can pulling out with very comfortable Out.

In the present embodiment, for the extension and contraction control for further facilitating elastic clamping block 8, it is preferable that the elastic clamping block 8 wraps The medical silica-gel set for including spring and being sheathed on outside the spring.

In the present embodiment, position replacement is carried out between guide groove 5 and the first bayonet 3 to further facilitate elastic clamping block 8, Preferably, the upper and lower surfaces of the elastic clamping block 8 are ramp-like guide face.

In the present embodiment, to further facilitate infusion control, it is preferable that be connected with air inlet pipe 9 on the conduit 1.

A kind of infusion device provided by the utility model is described in detail above.It is used herein specifically a Example is expounded the principles of the present invention and embodiment, this reality that the above embodiments are only used to help understand With novel method and its core concept.It should be pointed out that for those skilled in the art, not departing from this Under the premise of utility model principle, several improvements and modifications can be made to this utility model, these improvement and modification are also fallen Enter in the protection scope of the utility model claims.
