US 12,178,955 B2 · Securing control of settings of wound therapy apparatuses

Abstract

Embodiments of secure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, the apparatus includes a pressure source, a user interface, and a locking mechanism. The locking mechanism can be in one of at least two states, the at least two states including a first state in which the locking mechanism physically prevents user adjustment of one or more operational parameters with the user interface and a second state in which the locking mechanism does not physically prevent user adjustment of the one or more operational parameters with the user interface. The locking mechanism can include an authentication key and a receiver configured to receive an authentication input, which may be compared to the authentication key. Providing a sufficiently matching authentication input can transition the locking mechanism from the first state to the second state, permitting adjustments to the one or more operational parameters.

Dependent claims

A wound therapy apparatus comprising:

a pressure source configured to provide negative pressure via a fluid flow path to a wound dressing and operate according to an operational parameter;
a user interface configured to enable a user adjustment of the operational parameter;
and
a locking mechanism configured to:
operate in at least two states comprising a first state in which a cover of the locking mechanism prevents the user adjustment of the operational parameter with the user interface and a second state in which the cover permits the user adjustment of the operational parameter with the user interface;
and
transition from the first state to the second state by retracting the cover or permitting removal of the cover responsive to a manipulation of the locking mechanism with a physical key or a match between an authentication input and an authentication key.

4 more elements

A method of operating a negative pressure wound therapy apparatus, the method comprising:

at a first time:
providing negative pressure via a fluid flow path to a wound dressing with a pressure source operating according to an operational parameter;
and
with a locking mechanism that comprises a cover, preventing a user adjustment of the operational parameter with a user interface while the locking mechanism is in a first state;
and
at a second time:
determining that an authentication input matches an authentication key;
in response to determining that the authentication input matches the authentication key, transitioning the locking mechanism from the first state to a second state by retracting the cover or permitting removal of the cover;
permitting the user adjustment of the operational parameter with the user interface while the locking mechanism is in the second state;
and
providing negative pressure via the fluid flow path to the wound dressing with the pressure source operating according to the operational parameter after the user adjustment of the operational parameter.
