Description

Technical Field

[0001] This utility model relates to the field of intensive care units, specifically a nursing bed for convenient patient transfer in intensive care units. Background Technology

[0002] Traditional ICU beds often rely excessively on manual patient transport, resulting in several drawbacks: Insufficient positional adjustment: Traditional beds only support overall height adjustment or segmented tilting of the headboard and footboard, failing to provide coordinated adjustment for the back and lower limbs. This makes it difficult to easily transfer patients from the side, increasing the risk of sudden changes in position, pain, or secondary injury. Low transfer efficiency: Multiple medical staff are required for operation, especially in confined spaces where collisions between the bed and equipment are likely. Safety deficiencies: Fixed guardrails may hinder transfer operations, while removable guardrails require additional steps and pose a risk of patient falls.

[0003] Therefore, there is a need for a nursing bed that allows for easy patient transfer in the ICU to replace the existing nursing beds. This would solve the problem of patients being difficult to transfer easily from the side of the nursing bed, and would also automatically adjust the patient's back and lower limbs, and be equipped with movable guardrails to address the lack of protection. Utility Model Content

[0004] The purpose of this invention is to provide a nursing bed for convenient patient transfer in the intensive care unit, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nursing bed for convenient patient transfer in a monitoring room, comprising a nursing bed frame, a mechanical shaft rotatably connected to the center of the nursing bed frame, a seat plate fixedly connected to the mechanical shaft within the nursing bed frame, a second rotating shaft rotatably connected to the left side of the seat plate, a back plate fixedly connected to the second rotating shaft, a groove provided at the bottom of the back plate, a drive frame fixedly connected to the left end face of the seat plate below the back plate, a threaded shaft rotatably connected within the drive frame, a threaded slider slidably connected to the drive frame to the left and right, the threaded slider being threadedly connected to the threaded shaft, and a connecting frame fixedly connected to the upper end face of the threaded slider, the back plate being rotatably connected to the threaded shaft. A first rotating shaft is located on the left side of the groove. A connecting rod is rotatably connected between the first rotating shaft and the connecting frame. A third rotating shaft is rotatably connected to the right side of the seat. The third rotating shaft is fixedly connected to the base plate. By rotating the machine shaft, the seat is rotated 90 degrees, and the patient is turned towards the nursing bed frame. Rotating the threaded shaft moves the threaded slider to the left. The connecting rod drives the back plate to rotate around the second rotating shaft, supporting the patient's back. Rotating the third rotating shaft drives the base plate to rotate downward, lowering the patient's lower legs. This allows the patient to safely and quickly switch to a sitting position, improving the efficiency and safety of subsequent transfers.

[0006] The nursing bed frame is fixedly connected to two symmetrical side panels, each of which is slidably connected to an adjustable protective frame. A connecting plate located on the lower side of the nursing bed frame is fixedly connected between the adjustable protective frames. Two symmetrical electric push rods are fixedly connected to the lower end of the nursing bed frame. The electric push rods are poweredly connected to the connecting plate and can drive the connecting plate to move up and down. This allows the adjustable protective frames to move up and down to protect the patient and also allows the adjustable protective frames to be lowered to avoid obstructing the rotation of the seat.

[0007] Preferably, the lower side of the nursing bed frame is provided with two symmetrical fixed base plates. The upper surface of each fixed base plate is fixedly connected with two symmetrical limiting rods. The lower surface of the nursing bed frame is fixedly connected with two symmetrical limiting tubes. The limiting tubes are slidably connected to the limiting rods. A spring located inside the limiting tube is fixedly connected between the upper surface of the limiting rod and the lower surface of the nursing bed frame. A hydraulic cylinder is fixedly connected to the upper surface of each fixed base plate. The hydraulic cylinder is poweredly connected to the nursing bed frame. The hydraulic cylinder can drive the limiting rods to move up and down, thereby sharing the pressure on the hydraulic cylinder through the spring. The spring is always in a compressed state. By lowering the nursing bed frame through the hydraulic cylinder, the patient can be moved down as much as possible and transferred to a wheelchair, avoiding the transfer risks caused by height differences.

[0008] Preferably, a first motor is fixedly connected to the lower end face of the nursing bed frame. The first motor can drive the machine shaft to rotate, thereby driving the patient on the back plate, the seat plate and the bottom plate to rotate to one side of the nursing bed frame.

[0009] Preferably, a second motor is fixedly connected to the left end face of the drive frame, the second motor is poweredly connected to the threaded shaft, the second motor can drive the threaded shaft to rotate, and a machine groove is provided on the right side of the threaded slider, a third motor is fixedly connected in the machine groove, the third motor is poweredly connected to the third rotating shaft, and the third motor can drive the third rotating shaft to rotate;

[0010] Preferably, a cotton sheet is provided on the upper side of the seat board, and three soft mattress cores are wrapped inside the cotton sheet. The sizes of the three soft mattress cores correspond to the back board, the seat board and the bottom board respectively, so as to prevent the patient from slipping when adjusting the posture.

[0011] Preferably, the cotton bed sheet is fixedly connected to the underside of multiple adhesive strips, and the upper surfaces of the back panel, the seat panel, and the bottom panel are respectively fixedly connected to two adhesive strips aligned vertically with the adhesive strips, thereby enabling the cotton bed sheet to be adhered to the back panel, the seat panel, and the bottom panel, preventing the cotton bed sheet and the soft mattress core from slipping off.

[0012] Preferably, an intelligent controller is fixedly connected to the right side of the nursing bed frame. The intelligent controller controls the third motor, the first motor, the second motor, the hydraulic cylinder, and the electric push rod.

[0013] Preferably, the upper end face of the nursing bed frame is fixedly connected with two symmetrical fixed protective frames, which provide further protection for the patient.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a nursing bed frame, a seat, and connecting rods. A first motor drives the seat to rotate, which in turn rotates the backrest and base, allowing the patient to be moved to the side of the nursing bed frame for easy transfer. A second motor drives a threaded shaft to rotate, which in turn moves a threaded slider to the left, using the connecting rods to support the backrest and thus lift the patient's back. A third motor drives the base to rotate downwards at a suitable angle, slowly lowering the patient's lower limbs. This allows the patient to sit up safely and conveniently, avoiding the risk of injury from bumps and falls when a patient is helped to sit up while lying down.

[0016] This invention incorporates an electric push rod, an adjustable protective frame, and a spring. When the patient is on the bed, the adjustable protective frame is at its highest point to prevent the patient from falling. When the patient needs to be transferred, the electric push rod lowers the protective frame to avoid obstructing the rotation of the seat. Simultaneously, the spring remains compressed to share the pressure borne by the hydraulic cylinder, which in turn moves the nursing bed frame up and down. When transferring the patient, the nursing bed frame is lowered to facilitate the transfer to a wheelchair, avoiding any danger caused by height differences. Attached Figure Description

This allows the cotton bed sheet 102 to be adhered to the back panel 104, the seat panel 105, and the bottom panel 106, preventing the cotton bed sheet 102 and the soft mattress core 115 from slipping off.

[0034] Example 2:

[0035] Please see Figure 1-9 To prevent patients from falling off the nursing bed and to facilitate the adjustment of the height of the nursing bed frame 100, an adjustable protective frame 103, a spring 116, and a hydraulic cylinder 112 are provided.

[0036] The nursing bed frame 100 is fixedly connected to two symmetrical side panels 117. Each side panel 117 is slidably connected to an adjustable protective frame 103. A connecting plate 107 located on the lower side of the nursing bed frame 100 is fixedly connected between the adjustable protective frames 103. Two symmetrical electric push rods 108 are fixedly connected to the lower end of the nursing bed frame 100. The electric push rods 108 are poweredly connected to the connecting plate 107. The electric push rods 108 can drive the connecting plate 107 to move up and down, thereby driving the adjustable protective frame 103 to move up and down to protect the patient. The adjustable protective frame 103 can also be lowered to avoid obstructing the rotation of the seat board 105.

[0037] The nursing bed frame 100 has two symmetrically arranged fixed base plates 109 on its lower side. Two symmetrically arranged limiting rods 110 are fixedly connected to the upper surface of each fixed base plate 109. Two symmetrically arranged limiting tubes 111 are fixedly connected to the lower surface of the nursing bed frame 100. The limiting tubes 111 are slidably connected to the limiting rods 110, and springs 116 located within the limiting tubes 111 are fixedly connected between the upper surface of each limiting rod 110 and the lower surface of the nursing bed frame 100. Hydraulic cylinders 112 are fixedly connected to the upper surface of the base plate 109. The hydraulic cylinders 112 are powered to the nursing bed frame 100. The hydraulic cylinders 112 can drive the limiting rod 110 to move up and down. The pressure on the hydraulic cylinders 112 is shared by the spring 116, and the spring 116 is always in a compressed state. By moving the nursing bed frame 100 down by the hydraulic cylinders 112, the patient can be moved down as much as possible and transferred to a wheelchair, avoiding the transfer risks caused by height differences.

[0038] A smart controller 113 is fixedly connected to the right side of the nursing bed frame 100. The smart controller 113 controls the third motor 131, the first motor 114, the second motor 123, the hydraulic cylinder 112, and the electric push rod 108.

[0039] The nursing bed frame 100 has two symmetrical fixed protective frames 101 fixedly connected to its upper end, which provide further protection for the patient.

[0040] Working principle:

[0041] First, place the cotton sheet 102 containing the soft mattress core 115 inside the nursing bed frame 100 and fix it by using the adhesive tape 132 and the adhesive tape 127. Initially, adjust the protective frame 103 to the highest position, and the spring 116 is always in a compressed state. The spring 116 shares the pressure on the hydraulic cylinder 112.

[0042] When a patient needs to be transferred, the caregiver uses the intelligent controller 113 to control the hydraulic cylinder 112. The hydraulic cylinder 112 moves the nursing bed frame 100 down to its lowest position, and through the electric push rod 108, it moves the connecting plate 107 and the adjusting protective frame 103 down, so that the upper surface of the adjusting protective frame 103 is flush with the lower surface of the seat 105. Then, the intelligent controller 113 controls the first motor 114 to rotate the seat 105, backrest 104, and base plate 106 to one side of the nursing bed frame 100. In conjunction with the second motor 123, the threaded shaft 122 rotates, which in turn moves the threaded slider 125. The threaded slider 125 moves the connecting rod 120 to support the backrest 104, which in turn supports the patient. The backrest is rotated by the third motor 131, which drives the third rotating shaft 129 to rotate the base plate 106 slowly downwards, allowing the patient's lower legs to be lowered. This allows the patient to easily and safely switch from a lying position to a sitting position, and with the assistance of a caregiver, can be safely and quickly transferred to a wheelchair for further movement. Conversely, the patient can be transferred to the nursing bed frame 100. The protective frame 103 is adjusted upwards to prevent the patient from falling. The hydraulic cylinder 112 moves the nursing bed frame 100 up and down to adjust its height. The limiting tube 111 and the limiting rod 110 improve the stability of the nursing bed frame 100 during movement, and the spring 116 shares the pressure of the hydraulic cylinder 112, further improving the stability of the nursing bed.
