Abstract

Disclosed is a skin securable therapeutic fluid dispensing device that includes a reservoir adapted to retain therapeutic fluid, a pump driving mechanism, and at least one housing configured to accommodate the reservoir and the pump driving mechanism, with at least a portion of the at least one housing defining at least a portion of the reservoir. The device also includes a shield coupled to the at least one housing, the shield configured to protect, at least in part, the reservoir from application of external forces thereon.

Claims

1. A therapeutic fluid dispenser comprising:

a reservoir for storing a therapeutic fluid;

a pump driving mechanism having a motor;

a dispenser housing configured to accommodate the reservoir and the pump driving mechanism; and

a shield directly coupled to an exterior face of the dispenser housing, the shield having a longest longitudinal length smaller than a corresponding length of the dispenser housing and configured to protect, at least in part, the reservoir from one or more external forces acting on the shield, the shield being spaced from the reservoir to define an air gap therebetween.

2. The dispenser according to claim 1, wherein the dispenser housing comprises at least one protrusion receivable within a corresponding at least one opening provided on the shield to enable proper alignment of the shield.

3. The dispenser according to claim 1, wherein the dispenser housing comprises a frame configured and arranged to support the shield and space the shield at a distance from the reservoir.

4. The dispenser according to claim 3, wherein the frame is further configured to divert the one or more external forces away from the dispenser housing.

5. The dispenser according to claim 1, wherein the dispenser housing defines at least a portion of the reservoir.

6. The dispenser according to claim 1, wherein the dispenser housing defines at least a wall of the reservoir, the air gap being defined between the shield and the wall of the reservoir defined by the dispenser housing.

7. The dispenser according to claim 1, wherein the dispenser housing comprises:

a first housing configured to accommodate at least a portion of the pump driving mechanism; and

a second housing coupleable to the first housing, the second housing being configured to accommodate at least a portion of the reservoir;

wherein the shield is coupleable to at least one of the first housing or the second housing.

8. The dispenser according to claim 1, wherein the dispenser housing is provided with a rim having a contour substantially matching a contour defined by edges of the shield to enable proper alignment of the shield.

9. The dispenser according to claim 1, wherein the shield is further configured to divert the one or more external forces to the cradle.

10. The dispenser according to claim 1, wherein the shield is rigidly attached to the dispenser housing via one or more of:

gluing, laser soldering, ultrasonic welding, and manufacturing the shield as an integral part of the at least one housing.

11. The dispenser according to claim 1, wherein the shield is made of a material selected from a group consisting of metal, polycarbonate, and a combination of the foregoing.

12. The dispenser according to claim 1, wherein the shield is configured to protect the dispenser from radiation.

13. The dispenser according to claim 1, wherein the shield is removable from the dispenser housing.

14. A therapeutic fluid dispenser comprising:

a first part including;

at least a portion of a pump driving mechanism having a motor; and

a first housing configured to accommodate the at least a portion of the pump driving mechanism;

a second part coupleable to the first part, the second part including;

a reservoir for retaining a therapeutic fluid; and

a second housing configured to accommodate the reservoir;

a shield directly coupled to an exterior face of the first housing and having a longest longitudinal length smaller than a corresponding length of a dispenser housing comprising the first housing and the second housing;

wherein the shield is spaced from the reservoir to define an air gap therebetween, and configured to protect, at least in part, the reservoir from one or more external forces thereon when the first part and the second part are coupled.
