Abstract

Elements are provided for absorbing shock, pressure, impact and/or other external forces exerted upon a therapeutic fluid delivery device during use to protect the device from physical and internal damage and, thereby, according to some embodiments, maintain (for example) regulated and continuous administration of therapeutic fluid into the body.

Claims

1. A skin securable fluid dispensing system for regulated delivery of a therapeutic fluid into a body, the system comprising:

a cradle configured for adhesion to a cutaneous region of the body;

a therapeutic fluid delivery device including a pump and a reservoir, the therapeutic fluid delivery device being configured for removable attachment to the cradle; and

at least one shock absorber provided on at least one of the cradle and the therapeutic fluid delivery device so as to be positioned between the cradle and the therapeutic fluid delivery device, and extending at least partly along a periphery between the cradle and the therapeutic fluid delivery device when the delivery device is attached to the cradle;

wherein the cradle defines a first opening to allow a cannula to protrude therethrough, and at least one second opening separate from the first opening to expose therethrough at least a portion of a surface of the therapeutic fluid delivery device to the cutaneous region of the body when the cradle is adhered to the cutaneous region of the body and the therapeutic fluid delivery device is attached to the cradle.

2. The system of claim 1, wherein the at least one shock absorber comprises one or more pads provided by at least one of the cradle and the therapeutic fluid delivery device.

3. The system of claim 2, wherein the one or more pads comprise one or more of an elastomeric material and a spring.

4. The system of claim 1, wherein the at least one shock absorber comprises one or more elastic members and/or is supported by one or more elastic members provided on at least one of the cradle and the therapeutic fluid delivery device.

5. The system of claim 1, wherein the at least one shock absorber comprises one or more elastic gaskets.

6. The system of claim 1, further comprising at least one further shock absorber provided at or adjacent an outlet port of the therapeutic fluid delivery device.

7. The system of claim 1, wherein the at least one shock absorber comprises one or more of an elastomeric material and a spring.

8. The system of claim 7, wherein the elastomeric material comprises rubber and/or silicon.

9. The system of claim 1, wherein the at least one shock absorber is removably coupled to at least one of the cradle and the therapeutic fluid delivery device.

10. The system of claim 1, wherein the therapeutic fluid delivery device comprises:

a disposable part comprising the reservoir; and

a reusable part comprising at least a portion of the pump;

wherein the reusable part is detachably connectable to the disposable part.

11. The system of claim 1, wherein the therapeutic fluid delivery device further comprises one or more buttons for controlling operation of the therapeutic fluid delivery device.

12. The system of claim 1, further comprising a remote control for controlling operation of the therapeutic fluid delivery device.

13. The system of claim 1, wherein the therapeutic fluid comprises insulin.

14. The system of claim 1, wherein the therapeutic fluid delivery device and the cradle include a connection means enabling disconnection and reconnection of the therapeutic fluid delivery device from and to the cradle.

15. The system of claim 14, wherein the connection means includes at least one latch located at the therapeutic fluid delivery device and at least one corresponding groove located at the cradle.

16. The system of claim 1, wherein the at least one shock absorber is configured to buffer physical contact between the therapeutic fluid delivery device and the cradle.

17. The system of claim 1, wherein the at least one shock absorber is configured to absorb external forces exerted by interaction between the therapeutic fluid delivery device and the cradle.

18. The system of claim 17, wherein the external forces include one or more of:

shock, pressure and impact.

19. The system of claim 1, wherein the at least one shock absorber is configured and arranged to prevent ingression of fluids into an interface between the therapeutic fluid delivery device and the cradle when the delivery device is attached to the cradle.

20. The system of claim 1, wherein the at least one shock absorber is placed along a perimeter of the cradle and supported by a cradle wall.

21. The system of claim 1, wherein at least one of the second opening is located between the reservoir of the therapeutic fluid delivery device and the cutaneous region of the body when the cradle is adhered to the cutaneous region of the body and the delivery device is attached to the cradle.
