Description

Connection conversion device for large-volume injector and small-volume injector

Technical Field

The utility model relates to an injector device field specifically indicates a connect conversion equipment that is used for big volume syringe and little volume syringe.

Background

In the process of autologous fat surgery, fat needs to be injected into a receiving area, and due to the fact that a large injector is large, medical staff cannot accurately master the fat injection amount in the injection process, fat in the large injector needs to be transferred into a small injector for injection; however, in the prior art, fat is easily exposed to air during injection into a small syringe through a large syringe, and the small syringe is also easily exposed to air.

Therefore, a connection switching device for a large syringe and a small syringe capable of accurately controlling the injection amount becomes a social problem to be solved urgently in the whole society.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to get into the air scheduling problem easily through big syringe with fat injection among the prior art in the little syringe.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a connect conversion equipment for big volume syringe and little volume syringe, includes first syringe and second syringe, be provided with the extension pipe between first syringe and the second syringe, be provided with the three-way valve between the one end of extension pipe and the first syringe, the one end of extension pipe is passed through the three-way valve and is connected with first syringe, be provided with the check valve between the other end of extension pipe and the second syringe, the other end of extension pipe passes through the check valve and is connected with the second syringe.

Further, the center of the extension pipe is arranged in a spiral structure.

Further, the diameter of the inner wall of the second syringe is larger than that of the first syringe.

Further, the three-way valve comprises a first port, a second port and a third port, wherein the first port is connected with the open end of the first syringe, the second port is connected with the extension tube, and the third port is used for being connected with the syringe needle.

Compared with the prior art, the utility model advantage lies in: by adopting the structure, the utility model injects the substance in the large injector into the small injector, the injection amount can be more accurately controlled by the small injector, and the structure of the spiral extension tube is adopted, thereby playing a role of extension and contraction, the whole conversion process is closed, and the contact with the air is avoided; the utility model has the advantages of simple structure, excellent performance suits to use widely in the society.

fig. 2 is a schematic view of a port configuration of a three-way valve.

As shown in the figure: 1. the device comprises a first injector, 2, a second injector, 3, an extension pipe, 4, a three-way valve, 5, a one-way valve, 6, a first port, 7, a second port, 8 and a third port.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a connect conversion equipment for big volume syringe and little volume syringe when concrete implementation, including first syringe 1 and second syringe 2, be provided with extension pipe 3 between first syringe 1 and the second syringe 2, be provided with three-way valve 4 between the one end of extension pipe 3 and the first syringe 1, the one end of extension pipe 3 is passed through three-way valve 4 and is connected with first syringe 1, be provided with check valve 5 between the other end of extension pipe 3 and the second syringe 2, the other end of extension pipe 3 passes through check valve 5 and is connected with second syringe 2.

As a further elaboration of the present invention, the center of the extension pipe 3 is a spiral structure.

As a further elaboration of the present invention, the inner wall diameter of the second syringe 2 is larger than the inner wall diameter of the first syringe 1.

As a further elaboration of the present invention, the three-way valve 4 includes a first port 6, a second port 7 and a third port 8, the first port 6 is connected with the open end of the first syringe 1, the second port 7 is connected with the extension tube 3, the third port 8 is used for being connected with the syringe needle.

The utility model relates to a concrete implementation process that is used for connection conversion equipment of big volume syringe and little volume syringe as follows: the utility model discloses when using, when the material in the second syringe 2 need be injected into first syringe 1, open check valve 4, rotate three-way valve 4 to first port 6, third port 8 and open, second port 7 closes, stimulate first syringe 1, promote second syringe 2 simultaneously, inhale the material in the second syringe 2 into first syringe 1, avoided contacting the air, after accomplishing, rotate three-way valve 4 to first port 6 and second port 7 and open, third port 8 closes, inject the receiving area through the syringe needle of first syringe 1; meanwhile, since the first syringe 1 is small in size, more accurate control of the injection amount can be achieved.

As the utility model discloses a further explanation, the utility model provides a three-way valve also can change into the check valve, can avoid manual process of twisting the moving, and easy operation is convenient.
