Brief description of the drawings
Fig. 1 is the three-dimensional exploded view of present embodiment injector system；
Fig. 2 is the partial enlarged drawing at A meanings in Fig. 1.
Embodiment
The utility model is described in further detail below by embodiment combination accompanying drawing.
As shown in Figures 1 and 2, a kind of injector system, including syringe body 1 and connecting tube 2, syringe body includes
Piston, push rod and syringe, piston are fixed on the top of push rod and are mutually encapsulated into inside syringe.The top of syringe body 1
Provided with connector portions 11, connector portions 11 have the first thread segment and the first clamping part, and connecting tube 2 has the second thread segment and the second card
Buckle, the first thread segment and the threaded connection of the second thread segment, the first clamping part and the second clamping part snap connection.Connected by screw thread
The dual connection for connecing and snapping connection, it is ensured that the reliability connected between connecting tube and syringe body.
As shown in Figures 1 and 2, a kind of syringe, including syringe body 1 and connecting tube 2, syringe body include living
Plug, push rod and syringe.Piston is fixed on the top of push rod, and piston and push rod are mutually encapsulated into the inside of syringe.Syringe sheet
The top of body 1 is provided with connector portions 11, and the connector portions 11 include inner tube 14 and the outer tube 15 around the inner tube, the internal face of outer tube 15
Provided with internal thread 16, and inner tube 14 at least partly stretches out outer tube 15 upwards.Connecting tube 2 includes the body 21 run through up and down, the pipe
The bottom of body 21 is provided with external screw thread 22, and the buckle 23 of body 21 is provided around at a certain distance from the top of the external screw thread 22.
The outer wall of connector portions outer tube is provided with two button columns 12 of the upward cantilever-shaped extension of one, and two button columns are on syringe
The axisymmetrical of body, the top of button column is provided with inclined spigot surface 17, and the lower section of spigot surface is provided with catching groove 13.
During cooperation, connecting tube is loaded into connector portions, the buckle of connecting tube and the catching groove of connector portions are clasped, and connecting tube
External screw thread and connector portions screw-internal thread fit, realize the firm connection between connecting tube and syringe body.
Present embodiment designs a kind of injector system with interlocking structure, is retaining traditional female Luer formula connection
In the case of structure, a buckle structure is added, a catching groove is added at injector system syringe end and in connecting tube pair
It should locate to increase a buckle, by being clasped for buckle and catching groove, realize reliable connection.The connected mode is irreversible, button
After board enters catching groove, it cannot take apart again, so as to ensure that the reliability of connection.Because syringe body is with being connected
Pipe is disposable product, is abandoned after single patient's use, therefore the attachment structure does not influence the normal use of product.
Above content is to combine specific embodiment further detailed description of the utility model, it is impossible to is assert
Specific implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, some simple deduction or replace can also be made.
