Abstract

This disclosure teaches a disposable inserter which includes a housing having arranged in a displaceable configuration an inserter assembly comprising a cannula assembly with a cannula, a manually operable member for displacing the inserter assembly from a retracted position to an advanced position in order to manually insert the cannula into the skin of a patient, a locking element for blocking or enabling displacement of the inserter assembly, and a coupling arrangement for coupling the disposable inserter to a reusable inserter for automatically displacing the inserter assembly from the retracted position to the advanced position in order to automatically insert the cannula into the skin of the patient.

First claim

What is claimed is:

1. A disposable inserter, comprising:
a housing;
an inserter assembly moveable relative to the housing from a retracted position to an advanced position, the inserter assembly comprising a cannula assembly with a cannula;
a manually operable member having an exterior surface that is accessible for a user's hand to contact and thereby move the manually operable member by hand relative to the housing, wherein the user manually moving the manually operable member moves the inserter assembly from the retracted position to the advanced position to thereby manually insert the cannula into skin of a patient;
a lock configured to block or enable movement of the inserter assembly; and
a coupling arrangement configured to couple the disposable inserter to a reusable inserter configured for automatically moving the inserter assembly from the retracted position to the advanced position to thereby automatically insert the cannula into the skin of the patient.

2. The disposable inserter according to claim 1 , wherein the housing has an outlet port configured to engage with a baseplate of an infusion system, the baseplate configured to be adhered to the skin of the patient, and wherein the cannula assembly is configured to be placed through the outlet port into a well of the baseplate when the inserter assembly is moved from the retracted position to the advanced position to thereby insert the cannula into the skin of the patient.

3. The disposable inserter according to claim 1 , wherein the lock is configured to block movement of the inserter assembly when the disposable inserter is not engaged with a baseplate of an infusion system, and the lock interacts with the baseplate when the disposable inserter is engaged with the baseplate of the infusion system to enable movement of the inserter assembly.

4. The disposable inserter according to claim 3 , wherein the lock is connected to the housing of the disposable inserter via a torsion joint, wherein the lock is configured to move as a function of whether the disposable inserter engages the baseplate of the infusion system.

5. The disposable inserter according to claim 1 , wherein the inserter assembly includes a needle assembly with a needle, wherein the needle assembly is configured to engage with the cannula assembly, wherein insertion of the cannula into the skin of the patient is facilitated by the needle.

6. The disposable inserter according to claim 5 , wherein the needle assembly is retractable from the advanced position to the retracted position while the cannula remains in the skin of the patient, whereby the needle is retracted from the skin of the patient.

7. The disposable inserter according to claim 1 , wherein the inserter assembly comprises a coupling assembly configured to couple the inserter assembly to the reusable inserter.

8. The disposable inserter according to claim 1 , wherein the housing comprises an elongate body.

9. The disposable inserter according to claim 1 , wherein the manually operable member comprises a manually displaceable sleeve that is displaceable along the housing and engages the inserter assembly to move the inserter assembly from the retracted position to the advanced position.

10. The disposable inserter of claim 1 , wherein when the disposable inserter is coupled to the reusable inserter, the manually operable member is covered by the reusable inserter and is inaccessible for manual operation.

11. The disposable inserter of claim 1 , wherein when the disposable inserter is coupled to the reusable inserter, the disposable inserter is positioned substantially inside the reusable inserter.

12. The disposable inserter of claim 1 , wherein the manual movement of the manually operable member is in the insertion direction of the cannula.

13. The disposable inserter of claim 1 , wherein when the disposable inserter is coupled to the reusable inserter, the manually operable member is inaccessible for manual operation.

14. An insertion system, comprising:
a disposable inserter, comprising:
a housing;
an inserter assembly moveable relative to the housing from a retracted position to an advanced position, the inserter assembly comprising a cannula assembly with a cannula;
a manually operable member configured to move the inserter assembly from the retracted position to the advanced position to thereby manually insert the cannula into skin of a patient; and
a lock configured to block or enable movement of the inserter assembly;

a coupling arrangement; and
a reusable inserter coupleable to the disposable inserter via the coupling arrangement, the reusable inserter configured to automatically move the inserter assembly from the retracted position to the advanced position to thereby automatically insert the cannula into the skin of the patient;
wherein, when the reusable inserter is uncoupled and removed from the disposable inserter, an exterior surface of the manually operable member is accessible for a user's hand to contact and thereby move the manually operable member by hand relative to the housing;
further wherein, when the disposable inserter is coupled to the reusable inserter, the manually operable member is covered by the reusable inserter and is inaccessible for gripping by the user.

15. The insertion system of claim 14 , wherein the reusable inserter comprises a release configured to activate a drive for automatically displacing the inserter assembly from the retracted position to the advanced position.

16. The insertion system according to claim 15 , comprising tensioning equipment configured to tension a drive spring of the drive.

17. The insertion system according to claim 16 , wherein the tensioning equipment comprises a tensioning knob configured to be turned to a predefined angle for tensioning the drive spring of the drive.

18. The insertion system according to claim 17 , wherein the predefined angle is about 360°.

19. The insertion system according to claim 16 , wherein the tensioning equipment includes a return stop.

20. The insertion system of claim 15 , wherein the reusable inserter is coupleable to the disposable inserter before, while or after the drive spring is tensioned.

21. The disposable inserter of claim 14 , wherein when the disposable inserter is coupled to the reusable inserter, the disposable inserter is positioned substantially inside the reusable inserter.

22. A disposable inserter, comprising:
a housing;
an inserter assembly arranged in the housing and moveable relative to the housing from a retracted position to an advanced position, the inserter assembly comprising a cannula assembly with a cannula;
a manually operable member having an exterior surface that is accessible for a user to grip from outside of the housing and thereby move the manually operable member relative to the housing, wherein the user manually moving the manually operable member moves the inserter assembly from the retracted position to the advanced position to thereby manually insert the cannula into skin of a patient;
a lock configured to block or enable movement of the inserter assembly; and
a coupling arrangement configured to couple the disposable inserter to a reusable inserter configured for automatically moving the inserter assembly from the retracted position to the advanced position to thereby automatically insert the cannula into the skin of the patient.

23. The disposable inserter of claim 22 , wherein the manual movement of the manually oper
