Description

Technical Field

[0001] The invention relates to the technical field of clinical treatment, in particular to a prone position ventilation multi-position support body position pad for a critical care unit (ICU). Background Art

[0002] Prone ventilation refers to a treatment method in which the patient is transferred from a supine position to a prone position for mechanical ventilation. It improves the patient's oxygenation and reduces the risk of ventilator-associated lung injury, thereby improving the patient's treatment success rate. The support pad can properly support the patient's body to avoid compression of the face, breasts, genitals and other parts, especially providing support for the patient's foot joints and soles, which can greatly reduce the risk of pressure sores in patients.

[0003] Existing prone ventilation multi-position support cushions used in critical care ICUs are usually made of soft, skin-friendly fabrics, such as cotton or synthetic fibers. These fabrics have good air permeability and moisture absorption, which can reduce irritation to the patient's skin and keep the skin dry. However, existing prone ventilation multi-position support cushions have a relatively simple structure and cannot effectively support the patient's feet and other joints. As a result, during prolonged prone ventilation, the feet and other joints are prone to pressure, deformation, poor blood circulation, and other problems, increasing the risk of pressure sores. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a prone ventilation multi-position support cushion for use in critical care units (ICUs), which solves the problem that the existing prone ventilation multi-position support cushion has a relatively simple structure and cannot effectively support the patient's feet and other joints, thereby increasing the risk of pressure sores.

[0012] Preferably, the transmission assembly includes a threaded block, the internal threads of the threaded block are connected to the outer wall of the bidirectional threaded rod, the upper surface of the threaded block is fixedly connected to a connecting plate, the outer wall of the threaded block is slidably connected to the inner bottom wall of the support frame, the outer wall of the connecting plate is slidably connected to the inside of the support frame, the upper surface of the connecting plate is fixedly connected to the lower surface of the head support pad, and the outer wall of the threaded block is fixedly connected to the outer wall of the sliding ring.

[0015] Preferably, the transmission component three includes a gear, the outer wall of the rotating shaft is fixedly connected to the inside of the gear, the tooth end of the gear is meshed with a tooth plate, the upper surface of the tooth plate is fixedly connected to the lower surface of the air cushion, and the outer wall of the tooth plate is slidably connected to the inside of the bed.

[0016] Preferably, the interior of the support block adopts a hollow design.

[0017] Working principle: The support block is used to provide a certain support effect for the patient's foot joints. Since the support block is made of a buffer layer and a gel layer, the excellent elasticity of the buffer layer and the gel layer itself can provide a good support and rebound effect for the patient's foot joints. In addition, its hollow design can effectively disperse the pressure on the foot. Through the mutual cooperation between the hand support pad, head support pad, chest support pad, knee support pad and support block, a certain support is provided to the patient's head, arms, chest, knee joints and feet. At the same time, the hollow design of the support block can effectively reduce the pressure on the bony protrusions, greatly reducing the probability of pressure sores in patients.

[0018] By rotating the cross plate, the bidirectional threaded rod is driven to rotate, which in turn drives the threaded block to move. When the threaded block moves, it drives the connecting plate to slide inside the bed. When the connecting plate slides, it drives the head support cushion to move, thereby achieving the effect of adjusting the position of the head support cushion to meet the needs of patients with different body shapes.

[0019] When the bidirectional threaded rod rotates, it will also drive the first wheel to rotate, further driving the conveyor belt to rotate. When the conveyor belt rotates, it will drive the second wheel to rotate, and then drive the rotating shaft to rotate inside the support frame. When the rotating shaft rotates, it will drive the gear to rotate, and further drive the tooth plate to move up and down. Since the tooth plate and the air cushion are fixedly connected, the movement of the tooth plate will drive the air cushion to move. Through the movement of the air cushion, auxiliary support is provided to the patient's shoulders and neck, thereby improving the patient's comfort.

[0020] The present invention provides a prone position ventilation multi-position support cushion for critical care ICU.

[0021] Beneficial effects:

[0022] 1. The present invention achieves a certain rebound support for the patient's foot joint through the buffer layer, gel layer and hollow design of the support block. The connecting block is pulled upward to drive the sliding column to move, which further drives the baffle to move. When the baffle moves, it will cooperate with the fixed block to compress the spring. When the sliding column moves, it will also drive the connecting column to move. When the connecting column moves to a suitable position, the connecting block is rotated to drive the connecting column to rotate so that it is fixed to the outer wall of the limit block, thereby achieving the effect of unlocking and fixing the support block and the bed. Through the mutual cooperation between the buffer layer, gel layer, connecting block, sliding column, baffle, spring, connecting column and limit block, not only the support effect on the patient's foot is improved, the patient is prevented from suffering from pressure sore symptoms, but also the position of the support block can be adjusted to meet the use needs of patients of different heights.

[0023] 2. The present invention drives the bidirectional threaded rod to rotate by rotating the cross plate, and then drives the threaded block to move. When the threaded block moves, it will drive the connecting plate to move, and the head support pad will move under the drive of the connecting plate, thereby realizing the adjustment of the position of the head support pad to meet the use needs of patients with different head shapes.

[0024] 3. When the bidirectional threaded rod of the present invention rotates, it will drive the first wheel to rotate, and further drive the conveyor belt to rotate. The second wheel will rotate on its own under the drive of the conveyor belt. When the second wheel rotates, it will drive the rotating shaft to rotate, and further drive the gear to rotate. When the gear rotates, it will drive the tooth plate to move up and down. Since the tooth plate and the air cushion are fixedly connected, the movement of the tooth plate will drive the air cushion to move synchronously, thereby achieving a certain auxiliary support effect on the patient's shoulders and neck.
