Prone Position Bed with Movable Support Racks for Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients in a prone position during surgical operations experience discomfort and breathing difficulties due to constant pressure on their nose, mouth, face, ears, chest, and abdomen, leading to potential pressure sores from existing hospital beds.
Innovation Solution
A prone position ventilation health bed with a rear and front bedstead system, featuring movable support racks and breathable pads, allows for adjustable positioning to prevent direct pressure on the head, face, chest, and abdomen, ensuring comfort and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the patient is placed in a prone position on a conventional bed, then the patient can undergo surgical operations on the back, spine, buttocks or legs, but the patient's nose, mouth, face, ears, chest, and abdomen are pressed by the bed, causing breathing difficulties, discomfort, and pressure sores
Solution Approach 1:
The bed is divided into a head portion and a foot portion that can be independently adjusted. The head portion can be elevated to create a gap between the patient's face and the bed surface, while the foot portion remains at a different angle to maintain proper positioning for surgical access to the back and lower body.
Solution Approach 2:
The bed incorporates adjustable and movable components that allow dynamic repositioning during surgery. The head portion can be elevated or lowered, and the overall bed angle can be adjusted to optimize both surgical access and patient comfort, preventing pressure on sensitive areas while maintaining prone position benefits.
2Object-affected harmful factors
If multiple cushions are used to support the patient's front body to prevent pressure sores, then pressure on cheeks, ears, chest, abdomen, and private parts is reduced, but the patient feels uncomfortable due to constant compression by the cushions
Solution Approach 1:
By elevating the head portion, the invention extracts the patient's face and upper chest away from the bed surface, eliminating the need for cushions in these critical areas. This removes the source of discomfort associated with cushion compression while maintaining pressure sore prevention.
Solution Approach 2:
The adjustable head portion allows dynamic control over the gap between the patient's body and the bed, enabling optimization of both pressure distribution and patient comfort throughout the surgical procedure.
3Stability of the object's composition
If the patient's face and body are constantly pressed by the bed, then the patient remains stable during surgery, but breathing conditions are affected and pressure sores develop
Solution Approach 1:
The bed provides dynamic adjustability where the head portion can be elevated to relieve pressure on the face and improve breathing, while the foot portion and overall bed structure maintain stability for surgical procedures. This allows real-time optimization of both breathing conditions and patient stability.

AI summary
A prone position ventilation health bed includes a front bedstead pivotally connected with a rear bedstead. The frame includes two side bars and a front crossbar connecting the two side bars. Two parallel fixed bars are transversely mounted between the two side bars. A head and face support rack is transversely arranged and movable between the front crossbar and one of the two fixed bars. A left chest and abdomen support rack and a right chest and abdomen support rack are longitudinally arranged between the two fixed bars. The left chest and abdomen support rack and the right chest and abdomen support rack are parallel with each other and are movable between the two fixed bars. Thus, the user's head, face, chest, and abdomen are exposed outward without being pressed when the user is situated at the prone position.
