Abstract

A cover system for selectively blocking insertion of unauthorized objects through an aperture of a restraint mount of a patient support apparatus is provided. The cover system includes a cover and an instrument having an interface. The cover includes a brace and a restrictor coupled to the brace. The brace attaches to the patient support apparatus adjacent to the aperture and the restrictor operates in a restrict mode blocks access to the aperture and a permit mode where the restrictor permits access to the aperture. The cover also includes a lock mechanism, which includes a keeper movable between a locked state where movement of the restrictor is inhibited and an unlocked state where movement of the restrictor is permitted. The keeper moves from the locked state to the unlocked state in response to selective engagement between the interface of the instrument and a receiver of the lock mechanism.

First claim

What is claimed is:

1. A cover system for selectively blocking insertion of unauthorized objects through an aperture of a restraint mount of a patient support apparatus, the cover system comprising:
an instrument having an interface; and
a cover including:
a brace configured for attaching to the patient support apparatus adjacent to the aperture,
a restrictor movably coupled to the brace and arranged for operation between:
a restrict mode where the restrictor is arranged relative to the brace to block access to the aperture of the restraint mount; and
a permit mode where the restrictor is arranged relative to the brace to at least partially permit access to the aperture of the restraint mount, and

a lock mechanism interposed between the brace and the restrictor, the lock mechanism including a receiver shaped to receive the interface of the instrument, and a keeper being movable between:
a locked state to inhibit movement of the restrictor relative to the brace to maintain the restrictor in the restrict mode; and
an unlocked state to permit movement of the restrictor relative to the brace to change operation of the restrictor between the permit mode and the restrict mode,

wherein the keeper of the lock mechanism moves from the locked state to the unlocked state in response to selective engagement occurring between the interface of the instrument and the receiver of the lock mechanism.

2. The cover system of claim 1 , wherein the brace of the cover is shaped to receive at least a portion of the restraint mount of the patient support apparatus.

3. The cover system of claim 1 , wherein the brace of the cover and at least a portion of the restrictor cooperate to block access to the restraint mount in the restrict mode.

4. The cover system of claim 1 , wherein the restrictor is pivotably coupled to the brace for movement about a restrictor axis between the restrict mode and the permit mode; and
wherein the restrictor extends between a first end and a second end, with the keeper arranged at the first end of the restrictor, and with the restrictor axis arranged at the second end of the restrictor such that movement of the restrictor about the restrictor axis in the unlocked state moves the keeper relative to the receiver of the lock mechanism.

5. The cover system of claim 1 , wherein the restrictor is pivotably coupled to the brace for movement about a restrictor axis between the restrict mode and the permit mode;
wherein engagement between the keeper and the restrictor in the locked state inhibits pivoting movement of the restrictor about the restrictor axis;
wherein the keeper is disposed adjacent to the receiver in the locked state; and
wherein the selective engagement between the interface of the instrument and the receiver of the lock mechanism is defined by movement of the interface along the receiver and into abutment with the keeper to move the keeper from the locked state to the unlocked state.

6. The cover system of claim 1 , wherein the brace includes a brace body defining an abutment surface; and
wherein the keeper is operatively attached to the restrictor and includes a resilient finger defining a retention face arranged to contact the abutment surface of the brace body in the locked state to inhibit movement of the restrictor relative to the brace in the locked state.

7. The cover system of claim 6 , wherein the resilient finger further defines a release face arranged adjacent to the receiver in the locked state; and
wherein the selective engagement between the interface of the instrument and the receiver of the lock mechanism is defined by movement of the interface along the receiver and into abutment with the release face of the resilient finger which brings the retention face out of contact with the abutment surface of the brace body to move the keeper from the locked state to the unlocked state.

8. The cover system of claim 6 , wherein the brace body defines an interior with the abutment surface being located at least partially within the interior;
wherein the resilient finger is disposed at least partially within the interior in the lock state and is movable out of the interior in the unlocked state; and
wherein the brace body defines an outer brace surface and a brace aperture formed in the outer brace surface and extending into communication with the interior, with the brace aperture defining the receiver.

9. The cover system of claim 6 , wherein the keeper is further defined as a first keeper and the receiver is further defined as a first receiver shaped to receive a first tab of the interface of the instrument;
wherein the lock mechanism further includes a second keeper movable independent of the second keeper, and a second receiver shaped to receive a second tab of the interface of the instrument;
wherein the first keeper and the second keeper cooperate to inhibit movement of the restrictor relative to the brace in the restrict mode; and
wherein the first and second keepers move from respective locked states to respective unlocked states in response to selective engagement occurring simultaneously between:
the first tab of the instrument and the first receiver of the lock mechanism, and
the second tab of the instrument and the second receiver of the lock mechanism.

10. The cover system of claim 9 , wherein the first keeper is disposed adjacent to the first receiver in the locked state and the second keeper is disposed adjacent to the second receiver in the locked state; and
wherein the selective engagement between the first tab of the instrument and the first receiver of the lock mechanism is defined by movement of the first tab along the first receiver and into abutment with the first keeper to move the first keeper from the locked state to the unlocked state; and
wherein the selective engagement between the second tab of the instrument and the second receiver of the lock mechanism is defined by movement of the second tab along the second receiver and into abutment with the second keeper to move the second keeper from the locked state to the unlocked state.

11. The cover system of claim 1 , wherein the restrictor is pivotably coupled to the brace for movement about a restrictor axis between the restrict mode and the permit mode;
wherein the receiver is pivotably coupled to the brace for movement about a receiver axis between a first receiver position and a second receiver position;
wherein the selective engagement of the interface of the instrument and the receiver of the lock mechanism is defined by rotational torque applied to the receiver from the interface which moves the receiver from the first receiver position to the second receiver position to move the keeper from the locked state to the unlocked state; and
wherein the brace includes a brace body defining a brace strap aperture arranged adjacent to the aperture of the restraint mount of the patient support apparatus in the permit mode, with at least a portion of the restrictor being arranged to block access to the brace strap aperture in the restrict mode to block access to both the brace strap aperture of the brace body and to the aperture of the restraint mount.

12. The cover system of claim 11 , wherein the brace body further defines a guide supporting the keeper of the lock mechanism for movement between the locked state and the unlocked state;
wherein the cover further includes a link operatively attached the receiver for concurrent movement about the receiver axis, the link defining a pivot mount;
wherein the keeper of the lock mechanism is pivotably coupled to the pivot mount such that pivoting movement of the receiver from the first receiver position to t
