Abstract

A portable device for transfusing medical fluid accommodated in a collapsible bag is provided. The portable device for transfusing medical fluid bagged in a collapsible bag comprises a container which includes a box-shaped body having a loading port for loading the bag of medical fluid and at least one fluid exit port, and a cove operably coupled to the box-shaped body for selective open/close the load port; a push plate movably disposed in the container and able to be displaced between a first position and a second position, wherein when the push plate is at the first position a space is defined within the container for receiving the bag of medical fluid and when the push plate is at the second position the space is reduced to a degree that the medical fluid in the collapsible bag is substantially discharged; a energy providing unit operably coupled to the push plate for providing energy required from displacing the push plate; and a lock/unluck means mounted to the container for operably locking the push plate at the first position or release the push plate to allow it to move to the second position.

Claims

1. A portable device for transfusing medical fluid accommodated in a collapsible bag comprising:

a container which includes a box-shaped body having a loading port for loading the bag of medical fluid and at least one fluid exit port, and a cove operably coupled to the box-shaped body for selective open/close the load port;

a push plate movably disposed in the container and able to be displaced between a first position and a second position, wherein when the push plate is at the first position a space is defined within the container for receiving the bag of medical fluid and when the push plate is at the second position the space is reduced to a degree that the medical fluid in the collapsible bag is substantially discharged;

a energy providing unit operably coupled to the push plate for providing energy required from displacing the push plate; and

a lock/unlock means mounted to the container for operably locking the push plate at the first position or release the push plate to allow it to move to the second position.

2. A portable device for transfusing medical fluid accommodated in a collapsible bag according to claim 1, wherein the energy providing unit comprises a set of springs which are consisted of at lest one spiral springs.

3. A portable device for transfusing medical fluid accommodated in a collapsible bag according to claim 1, wherein the box-shaped body further comprises a stopping means for stopping the push plate at the second position.

4. A portable device for transfusing medical fluid accommodated in a collapsible bag according to claim 2, wherein the box-shaped body is consisted of a bottom and four sidewalls and has a top opening which serves as a loading port for loading/unloading the collapsible bag.

5. A portable device for transfusing medical fluid accommodated in a collapsible bag according to claim 4, wherein at lest one first spring holding member is provided at the bottom of the box-shaped body for coupling one end of the at least one spiral spring and at lest one first spring holding member is provided at a lower face of the push plate for coupling the other end of the at least one spiral spring.

6. A portable device for transfusing medical fluid accommodated in a collapsible bag according to claim 4, wherein the stop means is designed such that an upper surface of the push plate will be flush with the top face of the sidewalls while the push plate is stopped at the second position by the stop means.

7. A portable device for transfusing medical fluid accommodated in a collapsible bag according to claim 1, wherein the box-shaped body further comprises a first lock member and the cover comprises a second lock member for engaging with the first lock member so as to lock the clove to the box-shaped body while the cover close the loading port of the box-shaped body.
