Description

Technical Field

[0001] The present invention relates to the field of electric hospital beds, and in particular to a four-post ICU electric hospital bed capable of real-time monitoring and early warning. Background Art

[0002] The four-post ICU electric bed is a high-end medical device designed specifically for intensive care units. It aims to provide excellent patient care and convenient operating experience. It combines modern technology and innovative design to meet the complex care needs of critically ill patients and reduce the workload of medical staff. Through the real-time monitoring function of the bed, it can provide early warning of the patient's behavior and promptly inform the doctor of the patient's action status.

[0003] The four-post ICU electric bed with real-time monitoring and early warning is capable of a variety of bed positions. The bed can automatically push up the patient's upper body to allow the patient to sit up, changing the stress points of the patient's body and making it more comfortable for patients to lie in bed for a long time. However, the existing four-post electric beds can only allow patients to lie on their front and it is difficult to provide lateral support for patients. Patients who lie in bed for a long time find it difficult to turn over and are not comfortable enough.

The leg lifting portion 7 can drive one end of the leg support plate 6 to move, fold the two support plates hinged to each other, and lift the patient's knees to allow the patient's body to move, improve blood dynamics and assist body activities.

[0079] The use process of the four-post ICU electric bed capable of real-time monitoring and early warning provided by the present invention is as follows:

[0080] 1. Tilt adjustment at both ends of the bed: Start the hydraulic push rods 11 at both ends of the top surface of the four-column base 1 to tilt the head and foot ends of the electric bed.

[0081] 2. Leg support adjustment: start the drive motor 72 to drive the screw 71 to rotate, and the screw 71 can drive the screw 71 to drive the seat to move, thereby driving the left calf board 611 and the right calf board 621 to move toward the side of the left thigh board 61 and the right thigh board 62. During the movement of the left calf board 611 and the right calf board 621, the left foot board 613 and the right foot board 623 will slide along, so that the thigh board is pushed by the calf board to fold, and the patient's thigh position is lifted.

[0082] It should be noted that: when the calf board applies a thrust to the thigh board, since there is a push seat on the push board on the bottom surface of the calf board, the calf board will be subjected to the thrust applied by the spring 634 to the support plate 632 and the T-shaped slider when rotating. The support plate 632 is used to support the top surface of the side body chassis 2 to apply an upward force to the calf board. When the calf board and thigh board descend, the calf board will apply pressure to the support plate 632 and the T-shaped slider 633, pressing the T-shaped slider 633 to the inner side of the elastic storage tube 631, so that the calf board is in a parallel state. When adjusting the leg support action, the two sets of side body chassis 2 need to be in a parallel state.

[0083] 3. Back lifting adjustment: The electric push rod 84 is started, and the electric push rod 84 is supported on the top surface of the cross bar 83 through the bottom end. The output end of the electric push rod 84 uses the supporting force of the cross bar 83 to push the left horizontal frame 41 and the right horizontal frame 42 of the back support plate 4, and rotates around the hinge point of the side frame 2 hinged with it, thereby realizing the rotation of the back support plate 4, and propping up the patient lying on it to the upper side to put it in a sitting state.

[0084] 4. Sideways tilt and turning adjustment: Start the hydraulic push rods 11 on both sides of the top surface of the four-column base 1 to push upward. At this time, the lifted sideways chassis 2 will move up. During the upward movement of a group of sideways chassis 2, the servo motor 25 inside the upwardly moving sideways chassis 2 will be driven with the upward movement height, and the positioning control gear 26 will be driven to rotate through its output shaft.

[0085] When one group of sideways chassis 2 moves up, the balancing extension frame 3 connected between the two groups of sideways chassis 2 will be subjected to pulling force and rotational driving force, causing the sliding rod 31 to slide toward the outside of the sliding sleeve rod, and due to the upward movement of one group of sideways chassis 2, the transmission gear 34 connected on both sides of the fixed shaft 33 at one end of the sliding rod 31 or the storage sleeve rod 32 will engage with the positioning and regulating gear 26 and rotate. At this time, the driving force provided by the servo motor 25 to the positioning and regulating gear 26 is the rotation stroke of the sliding rod 31 or the storage sleeve rod 32 for tilting and rotating. When one group of sideways chassis 2 is completed to move up, the servo motor 25 will stop driving, and at the same time, the electrical lock shaft component 27 connected to the output end of the servo motor 25 will lock the driving shaft of the servo motor 25, so that the sideways chassis 2 cannot rotate due to its own gravity.

[0086] And due to the rotation stroke provided by the servo motor 25, only the sliding rod 31 and the storage sleeve rod 32 are tilted to provide a rotation stroke for the transmission gear 34. Then, the two sets of side body frames 2 will be in a horizontal state after the lifting is completed, and the middle balance extension frame 3 will be in a tilted state. The back support plate 4, hip support plate 5, and leg support plate 6 connected to the top of the side body frame 2 will also be in a middle tilted state. At this time, the side body tilt adjustment of the ICU electric bed can be completed.

[0087] It should be noted that during the lifting and lowering of the side body frame 2, since the back support plate 4, the hip support plate 5, and the leg support plate 6 all adopt a separated design on both sides, and the middle part adopts a sliding plate and a storage plate structure, after the tilt adjustment of the side body frame 2 is completed, the ICU electric bed can have a middle tilt function for the bed body. At the same time, the side body tilt function can be flexibly used to allow the patient to flip the patient's body to one side when the patient is unable to turn over, so that the patient can complete the turning over.

[0088] It should be noted that when the ICU electric bed is in use, it can protect the patient from turning over through the protective baffles on both sides of the bed. At the same time, when the patient turns over, the built-in camera mechanism and monitoring alarm mechanism inside the protective baffle can monitor the patient in real time and remind the doctor of the patient's physical condition at all times.

[0089] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
