Bariatric bed apparatus and methods
View Patent ↗A bariatric hospital bed with full feature capability to enhance the care and treatment of bariatric patients. Among the features are fully adjustable and retractable siderails, bed raise-and-lower features, head-up and leg-down features for converting to a seated position, as well as Trendelenburg and reverse-Trendelenburg features. An integral scale assembly and radioluscent capabilities with a built'in X-ray tray are also provided together with redundant, easy-access controls in a pendant as well as in both siderails. An improved footboard is also provided for use as both a foot-rest and a step.
1. A side rail assembly for a hospital bed, the side rail assembly comprising an adjustment mechanism, wherein the adjustment mechanism is configured to:
maintain the side rail assembly at a first height position;
maintain the side rail assembly at a second height position, wherein the second height position is higher than the first height position;
maintain the side rail assembly at a third height position, wherein the third height position is higher than the second height position;
allow lateral translation of the side rail assembly between a first width position and a second width position when the side rail assembly is at the first height position;
allow lateral translation of the side rail assembly between the second width position and a third width position when the side rail assembly is at the second height position; and
restrict lateral translation of the side rail assembly between the second width position and the third width position when the side rail assembly is at the third height position.
2. The side rail assembly of claim 1 , wherein the adjustment mechanism is configured to allow the side rail assembly to be lowered from the third height position to the second height position when the side rail assembly is in the third width position.
3. The side rail assembly of claim 1 , wherein the adjustment mechanism is configured to allow the side rail assembly to be lowered from the third height position to the second height position when the side rail assembly is in the second width position.
4. The side rail assembly of claim 1 , wherein the adjustment mechanism is coupled to a support frame and wherein the side rail assembly is beneath the support frame when the side rail assembly is in the first height position and the first width position.
5. The side rail assembly of claim 1 wherein the adjustment mechanism comprises a lever configured for manual articulation to lower the side rail assembly from the third height position to the second height position or to lower the side rail assembly from the second height position to the first height position.
6. The side rail assembly of claim 1 wherein the adjustment mechanism comprises a pawl that engages a set of teeth on a shaft.
7. The side rail assembly of claim 1 wherein the adjustment mechanism comprises a ratchet mechanism.
8. A bed comprising:
a support frame;
a side rail assembly coupled to the support frame; and
an adjustment mechanism, wherein:
the adjustment mechanism is configured to maintain the side rail assembly at a first height position, a second height position, and a third height position, wherein the third height position is above the second height position, and wherein the second height position is above the first height position;
the adjustment mechanism is configured to allow the side rail assembly to translate laterally to a first width position when the side rail assembly is in the first height position, wherein the first width position is underneath the support frame; and
the adjustment mechanism is configured to restrict lateral translation when the side rail assembly is in the third height position.
9. The bed of claim 8 wherein the adjustment mechanism is configured to allow the side rail assembly to translate laterally from the first width position to a second width position when the side rail assembly is at the first height position, and wherein the adjustment mechanism is configured to allow the side rail assembly to be raised from the first height position to the second height position when the side rail assembly is at the second width position.
10. The bed of claim 9 , wherein the adjustment mechanism is configured to allow the side rail assembly to be raised from the second height position to the third height position when the side rail assembly is at the second width position.
11. The bed of claim 10 , wherein the adjustment mechanism is configured to allow the side rail assembly to translate laterally from the second width position to a third width position when the side rail assembly is at the second height position.
12. The bed of claim 11 , wherein the adjustment mechanism is configured to allow the side rail assembly to be lowered from the third height position to the second height position when the side rail assembly is in the third width position.
13. The bed of claim 8 wherein the adjustment mechanism comprises a lever configured for manual articulation to lower the side rail assembly from the third height position to the second height position or to lower the side rail assembly from the second height position to the first height position.
14. The bed of claim 8 wherein the adjustment mechanism comprises a pawl that engages a set of teeth on a shaft.
15. The bed of claim 8 wherein the adjustment mechanism comprises a ratchet mechanism.
