Abstract

In a method for selectively enabling or blocking the use of medical equipment made available by a vendor or a system option in the medical equipment, for a customer, wherein the equipment is arranged in a facility of the customer, a compilation is created and stored at a vendor'"'"'s computer from which it proceeds whether the customer is permitted to use the medical equipment overall or which system option of the medical equipment the customer is permitted to use. Given a desired utilization of the medical equipment or a system option of the medical equipment by the customer, a check is made at the vendor'"'"'s computer as to see whether the customer is authorized for the use and whether costs arising from previous use are to be paid. The use is automatically enabled when the authorization still exists and no costs are outstanding, or the use is automatically inhibited when there is no authorization or costs are still outstanding.

Claims

1. A method for selectively enabling or blocking usage of a medical implement selected from the group consisting of medical equipment and a system option in said medical equipment, comprising the steps of:

for a customer of a vendor of said medical implement, said customer having a facility at which said medical implement is located, storing a compilation at a computer of said vendor which designates whether said customer is permitted to use said medical implement and to which extent said customer is permitted to use said medical implement;

when said customer desires to use said medical implement, establishing communication between a computer of said medical implement and said computer of said vendor and communicating usage data from said computer of said medical implement to said computer of said vendor;

based on said usage data, reviewing said compilation at said computer of said vendor to determine whether said customer is authorized to use said medical implement;

additionally reviewing, dependent on said compilation at said computer of said vendor, whether said customer has an economic relationship with said vendor permitting said use of said medical implement; and

automatically enabling said use of said medical implement by said customer by communicating enabling data from said computer of said vendor to said computer of said medical implement when, based on said review, said authorization and said economic relationship exist, and automatically communicating blocking data from said computer of said vendor to said computer of said medical implement if, based on said review, either of said authorization or said economic status does not exist.

2. A method as claimed in claim 1 wherein the step of reviewing whether said economic relationship exists between said customer and said vendor permitting said use by said customer of said medical implement comprises reviewing accumulated costs for said use of said medial implement in said compilation, and determining, at the time said usage data are communicated whether said costs have been paid by said customer.

3. A method as claimed in claim 1 comprising registering, in said compilation, each use of said medical implement by said customer.

4. A method as claimed in claim 1 comprising establishing an account between said customer and said vendor wherein said customer can pre-purchase authorization for a number of uses of said medical implement, and including information representing a status of said account in said compilation.

5. A method as claimed in claim 4 comprising automatically blocking said use of said medical implement by said customer if said information representing said status of said account indicates that said plurality of uses of said medical implement has been consumed.

6. A method as claimed in claim 1 comprising establishing an account between said customer and said vendor wherein said customer can pre-purchase use of said medical implement for a predetermined time duration, and including information representing a status of said time duration in said compilation.

7. A method as claimed in claim 6 comprising automatically blocking said use of said medical implement by said customer if said information representing said time duration indicates that said time duration has elapsed.

8. A method as claimed in claim 6 comprising monitoring elapsing of said time duration at said computer of said vendor.

9. A method as claimed in claim 1 comprising establishing a credit account between said customer and said vendor wherein said vendor extends credit to said customer for said use of said medical implement, and including information in said compilation representing a status of said credit account.

10. A method as claimed in claim 1 comprising periodically checking at said computer of said vendor, independently of said usage data, whether said economic status between said customer and said vendor exists permitting use of said medical implement, and if said economic status does not exist after a periodic check, automatically locking said use of said medical implement by said customer.

11. A method as claimed in claim 1 comprising the additional step of communicating payment data from said customer to said computer of said vendor for costs associated with said use of said medical implement and automatically crediting and account of said customer at said computer of said vendor for said payment.

12. A method as claimed in claim 11 comprising the additional step of after crediting said account of said customer for said payment, automatically communicating a receipt for said payment to said customer from said computer of said vendor.

13. A method as claimed in claim 1 wherein said communication between said computer of said medical implement and said computer of said vendor ensues via a communication network and wherein, upon a disruption of said communication network, repeatedly communicating said usage data from said computer of said medical implement to said computer of said vendor and repeatedly communicating said data for enabling or blocking said use of said medical implement by said customer from said computer of said vendor to said computer of said medical implement.

14. A method as claimed in claim 1 comprising communicating said usage data in a secure form selected from the group consisting of encryption and signing.

15. A method as claimed in claim 1 comprising communicating said data enabling or blocking said use of said medical implement by said customer in a secure form selected from the group consisting of encryption and signing.

16. A method as claimed in claim 1 comprising establishing a graduated cost schedule for said customer at said computer of said vendor for charging said customer for said use of said medical implement dependent on a degree of use by said customer of said medical implement.

17. A method as claimed in claim 1 comprising communicating examination-specific data, in addition to said usage data, from said computer of said medical implement to said computer of said vendor.
