Description

A new type of monitoring bed Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a novel monitoring bed. Background Technology

[0002] With advancements in medical care, medical monitoring beds have become essential equipment in hospital wards, especially in intensive care units (ICUs), cardiology departments, and postoperative care units for cardiac surgery. Traditional monitoring beds primarily provide simple position adjustments (such as raising and lowering the bed and adjusting the backrest) and basic protective functions. However, for the care of long-term bedridden or postoperative patients (especially those with cardiovascular diseases), existing monitoring beds have the following shortcomings: patient turning, toileting care, and pressure ulcer prevention still rely heavily on manual operation, which is not only inefficient but also highly susceptible to pulling, compressing, or contaminating various life support tubing and monitoring leads during movement, leading to serious risks such as catheter dislodgement, infection, and the induction of arrhythmias. Summary of the Invention

[0003] The purpose of this invention is to provide a novel monitoring bed that solves the problem that patients' turning over, excretion care, and pressure ulcer prevention still rely on a lot of manual operation, which is inefficient and can easily pull, compress, or contaminate various life support lines and monitoring leads during the moving process, leading to serious risks such as catheter dislodgement, infection, and arrhythmia.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a novel monitoring bed, including a bed frame, a turning mechanism above the bed frame, a mattress above the turning mechanism, a defecation port on the mattress, a sealing mechanism below the defecation port, and a bedpan lifting mechanism below the sealing mechanism; a headboard and a footboard are respectively provided on the front and rear sides of the bed frame, and liftable guardrails are provided on both the left and right sides of the bed frame; a base frame is provided below the bed frame, and casters are provided on the base frame; a height adjustment mechanism is provided between the bed frame and the base frame.

[0005] Furthermore, the turning mechanism includes two turning frames symmetrically arranged on the top surface of the bed frame, and each turning frame is provided with a drive component for driving the movement of the turning frame.

[0006] Furthermore, the drive assembly includes a first drive member disposed on the bottom surface of the bed frame, a first movable frame disposed at the working end of the first drive member, a slide rail disposed on the bottom surface of the bed frame, sliders at the left and right ends of the first movable frame moving along the slide rail, a first connecting rod disposed on the first movable frame, a second connecting rod disposed at the other end of the first connecting rod, and the second connecting rod being connected to the turning frame.

[0007] Furthermore, the mattress includes a fixed mattress, and flip-up mattresses are provided on both the left and right sides of the fixed mattress.

[0008] Furthermore, the top surface of the fixed mattress and the flipped mattress is provided with an anti-pressure sore functional layer. The anti-pressure sore functional layer includes multiple independent and controllable pressure adjustment units. The pressure adjustment units are laid flat on the entire upper surface support area of ​​the fixed mattress and the flipped mattress, and the multiple pressure adjustment units are arranged in a matrix array.

[0009] Furthermore, the distribution density of the pressure regulating units is greater in the regions corresponding to the sacrococcygeal region and / or ischial tuberosity than in other regions.

[0010] Furthermore, a turning-over driving layer is provided on the flipping mattress and below the pressure ulcer prevention functional layer, and a physical isolation layer is provided between the turning-over driving layer and the pressure ulcer prevention functional layer; the turning-over driving layer includes a first airbag, a second airbag, and a third airbag arranged along the longitudinal direction of the human body, the first airbag, the second airbag, and the third airbag corresponding to the shoulder, waist, and upper thigh areas of the human body, respectively, the first airbag, the second airbag, and the third airbag being connected to a four-way valve through a first bronchus, a second bronchus, and a third bronchus, respectively, the four-way valve being connected to an air pump through a main air pipe; when the first airbag, the second airbag, and the third airbag are inflated, they are inflated sequentially from the shoulder, to the waist, and then to the upper thigh.

[0011] Furthermore, the sealing mechanism includes a sealing plate that matches the defecation port. A support pad is provided on the top surface of the sealing plate. A limit plate is provided on the bottom surface of the bed frame. A movable plate is slidably mounted on the limit plate. Movable wheels are provided on the left and right sides of the movable plate. Limit grooves that match the movable wheels are provided on the limit plate. A third driving member for driving the movable plate to move is provided on the rear side of the limit plate. A first support frame is provided on the movable plate. A fourth driving member for driving the sealing plate to rise and fall is provided on the first support frame.

[0012] Furthermore, the toilet lifting mechanism includes a second support frame disposed above the base frame, a lifting platform disposed above the second support frame, a fourth link and a fifth link disposed between the lifting platform and the mounting seat located on the top surface of the second support frame, a gear disposed on the hinge shaft between the fourth link and the mounting seat, a limit seat disposed on the top surface of the second support frame, a third movable frame slidably disposed within the limit seat, a rack meshing with the gear disposed on the third movable frame, a threaded rod rotatably disposed on the second support frame, the threaded rod being threadedly connected to the third movable frame, and a rocker arm disposed at the exposed end of the threaded rod.

Each part of the mechanism can work independently or in conjunction, forming an integrated nursing solution covering body position change, pressure ulcer prevention, excretion treatment, safety protection and height adjustment.

[0015] The turning mechanism assists patients in turning over; the pressure-relief functional layer on the top surface of the fixed mattress and the flipping mattress will perform decompression or pressure reduction operations in the corresponding air chambers of the area that needs decompression, causing the mattress surface to sink slightly or soften, thereby reducing local pressure. At the same time, the surrounding air chambers can maintain overall support through coordinated adjustment; the turning drive layer on the flipping mattress, through the sequential inflation and deflation of airbags in the shoulder, waist and leg areas, smoothly and controllably assists patients in completing a full-body position change from supine to lateral.

[0016] The linkage design between the sealing mechanism and the bedpan lifting mechanism enables automatic and smooth opening and closing of the defecation port and precise lifting and docking of the bedpan. Patients can defecate while the bed sheet is flat, making the operation discreet and quick, greatly protecting the dignity of patients, and reducing the workload of bed sheet soiling and frequent changes.

[0020] As shown in Figure 1-13, a novel monitoring bed includes a bed frame 1. A turning mechanism is installed above the bed frame 1, and a mattress 3 is installed above the turning mechanism. A defecation port is provided on the mattress 3, and a sealing mechanism is provided below the defecation port. A bedpan lifting mechanism is provided below the sealing mechanism. A headboard 9 and a footboard 10 are respectively installed on the front and rear sides of the bed frame 1. Liftable guardrails 11 are installed on both the left and right sides of the bed frame 1. A base frame 16 is provided below the bed frame 1, and casters 17 with brake devices are installed on the base frame 16. A height adjustment mechanism is installed between the bed frame 1 and the base frame 16.

[0021] As shown in Figure 4, the turning mechanism includes two turning frames 2 symmetrically arranged on the top surface of the bed frame 1. Each turning frame 2 has a drive assembly below it for driving its movement. As shown in Figure 5, the drive assembly includes a first drive member 4 mounted on the bottom surface of the bed frame 1. A first movable frame 5 is mounted on the working end of the first drive member 4. A slide rail 6 is mounted on the bottom surface of the bed frame 1. The sliders at both ends of the first movable frame 5 move along the slide rail 6. A first connecting rod 7 is hinged to the first movable frame 5, and a second connecting rod 8 is hinged to the other end of the first connecting rod 7. The second connecting rod 8 is connected to the turning frame 2. Specifically, the first drive member 4 can be an existing component such as an electric push rod, a cylinder, or a hydraulic cylinder.

[0022] When the turning frame on one side (e.g., the left side) needs to be activated, the first drive component 4 on that side retracts, driving the first movable frame 5 connected to it to move precisely in a straight line (to the left) along the slide rail 6 mounted on the bottom surface of the bed frame 1. The movement of the first movable frame 5 is transmitted to the first connecting rod 7 through the hinge point. The first connecting rod 7 swings accordingly and pushes the second connecting rod 8 hinged to it. The second connecting rod 8, as the final link in the power transmission, applies the movement to the turning frame 2 connected to it. Under the pull of the second connecting rod 8, the turning frame 2 rotates around its connection point with the bed frame 1 or related support points, thereby achieving the lifting or turning movement, assisting the person on the bed to complete the lateral turning action. The working process of the turning frame 2 on the other side is exactly the same and independently controlled, enabling independent turning on one side or coordinated turning on both sides. By controlling the stroke and direction of the first drive component 4, the turning angle and speed of the turning frame can be precisely adjusted to meet different nursing needs.

[0023] The mattress 3 includes a fixed mattress 301, and flip mattresses 302 are connected to both the left and right sides of the fixed mattress 301.

[0024] Both the fixed mattress 301 and the flip mattress 302 have an anti-pressure sore functional layer installed on their top surfaces. This layer includes multiple independently controllable pressure adjustment units, which are laid flat across the entire upper surface support area of ​​both mattresses. These units are arranged in a matrix array. Each pressure adjustment unit is a columnar, sac-like, or honeycomb-shaped air chamber. The anti-pressure sore functional layer also includes an integrated pressure sensor array for real-time monitoring of the pressure values ​​in the corresponding areas of each pressure adjustment unit. Based on the data from the pressure sensor array, the controller performs targeted pressure reduction operations on the pressure adjustment units corresponding to areas where the pressure consistently exceeds a threshold. For areas requiring pressure reduction, the corresponding air chamber will perform decompression or deflation operations, causing the mattress surface to slightly sink or soften, thereby reducing local pressure. Simultaneously, surrounding air chambers can maintain overall support through coordinated adjustment.

[0025] As shown in Figure 6, the distribution density of the pressure regulating units is higher in the areas corresponding to the sacrococcygeal region and / or ischial tuberosity than in other areas. In areas prone to pressure sores, such as the sacrococcygeal region and / or ischial tuberosity, the system pre-arranges pressure regulating units and sensing units with a higher distribution density. This enables more precise pressure monitoring and more accurate, gentler pressure regulation in these critical areas, significantly improving the protection level of these key areas.

[0026] A turning-over driving layer is disposed on the flipping mattress 302 and below the pressure ulcer prevention functional layer, and a physical isolation layer is disposed between the turning-over driving layer and the pressure ulcer prevention functional layer. The physical isolation layer can be made of high-density slow rebound sponge (memory foam), high-elasticity polyurethane (PU) foam, or high-density hard cotton, which has good vertical support strength, can evenly distribute the pressure of the upper layer, and has sufficient flexibility to adapt to the undulation deformation of the airbags below. The slow rebound characteristics help to further buffer and absorb impact, reduce interference with the pressure sensing of the upper layer. These materials are easy to cut and process, and the cost is controllable.

[0027] As shown in Figure 7, the turning drive layer includes a first airbag 303, a second airbag 304, and a third airbag 305 arranged along the longitudinal direction of the human body. The first airbag 303, the second airbag 304, and the third airbag 305 correspond to the shoulder, waist, and upper thigh areas of the human body, respectively. The first airbag 303, the second airbag 304, and the third airbag 305 are connected to a four-way valve 307 through a first bronchus 308, a second bronchus 309, and a third bronchus 310, respectively. The four-way valve 307 is connected to an air pump through a main air pipe 306. When the controller controls the first airbag 303, the second airbag 304, and the third airbag 305 to inflate, they inflate in the order from the shoulder, to the waist, and then to the upper thigh.

[0028] Multiple pressure regulating units in the pressure ulcer prevention functional layer are laid flat and cover the entire upper surface support area of ​​the flip mattress 302; within the vertical projection area of ​​the first airbag 303, the second airbag 304, and the third airbag 305, the pressure regulating units are spatially and functionally separated from the first airbag 303, the second airbag 304, and the third airbag 305 through the physical isolation layer.

[0029] The air pump starts, and the four-way valve 307 switches to the corresponding working position, connecting the air path to the main air tube 306 of the target side-turning mattress 302. The controller, according to the preset shoulder, waist, and thigh sequence, controls the inflation of the corresponding airbags sequentially through the four-way valve 307. First stage (shoulder lifting): The first airbag 303 inflates preferentially through the first bronchus 308, slowly lifting the patient's shoulder area and initiating the lateral rotation of the upper body. Second stage (lumbar support): Subsequently, the second airbag 304 inflates through the second bronchus 309, providing support in the lumbar region, allowing the midsection of the body to follow the side-turn. Third stage (thigh stabilization): Finally, the third airbag 305 inflates through the third bronchus 310, raising the upper thigh, coordinating the lower body posture with the upper body, completing the entire body's lateral roll and stabilizing at the preset side-lying angle.

[0030] As shown in Figure 8, the sealing mechanism includes a sealing plate 22 that matches the defecation opening. A support pad 23 is installed on the top surface of the sealing plate 22. The support pad 23 is the same height as the mattress 3 and is spliced ​​together with the mattress 3 to block the defecation opening. A limit plate 26 is installed on the bottom surface of the bed frame 1. A movable plate 25 is slidably installed on the limit plate 26. Movable wheels 27 are installed on the left and right sides of the movable plate 25. The limit plate 26 has a limit groove that matches the movable wheel 27. The movable wheel 27 moves along the limit groove. A third driving member 24 for driving the movable plate 25 is installed on the rear side of the limit plate 26. A first support frame 28 is vertically connected to the movable plate 25. Two fourth driving members 29 for driving the sealing plate 22 to rise and fall are installed on the first support frame 28. Specifically, the third driving member 24 and the fourth driving member 29 can be existing components such as electric push rods, cylinders, and hydraulic cylinders.

[0031] When the defecation opening needs to be closed, the third drive unit 24 is activated, driving the connected movable plate 25 to move horizontally. The movable wheels 27 on both sides of the movable plate 25 roll along the limiting grooves on the limiting plate 26, causing the movable plate 25 to move steadily to directly below the defecation opening. Subsequently, the two fourth drive units 29 installed on the first support frame 28 are activated simultaneously, pushing the sealing plate 22 upward vertically. The support pad 23 on the top surface of the sealing plate 22 rises accordingly until its height is flush with the surrounding mattress 3 and it is tightly fitted with the mattress 3, thereby completely sealing the defecation opening and forming a flat bed surface.

[0032] When it is necessary to open the defecation opening, the fourth drive unit 29 reverses its action, driving the sealing plate 22 and the support pad 23 to descend vertically together, creating a defecation space; thereafter, the third drive unit 24 can drive the moving plate 25 to move horizontally away from its original position for subsequent nursing operations.

[0033] The third drive unit controls the horizontal position, and the fourth drive unit controls the vertical lifting, which realizes the precise and stable opening and closing of the sealing plate, ensuring the flatness of the bed surface while reliably opening and closing the defecation port.

[0034] As shown in Figure 9, the toilet lifting mechanism includes a second support frame 30 connected above the base frame 16. A lifting platform 31 is disposed above the second support frame 30. Mounting seats 34 are connected to the top surface of the second support frame 30 near the four corners. A fourth connecting rod 32 and a fifth connecting rod 33 are hinged between the lifting platform 31 and the mounting seats 34 located on the top surface of the second support frame 30. The bottom end of the fourth connecting rod 32 is hinged to the mounting seat 34 through a hinge shaft, and the top end of the fourth connecting rod 32 is hinged to the bottom end of the fifth connecting rod 33. The top end of the connecting rod 33 is hinged to the connecting seat on the lifting platform 31. A gear 37 is installed on the hinge shaft between the fourth connecting rod 32 and the mounting seat 34. A limiting seat 36 is installed on the top surface of the second support frame 30. A third moving frame 35 is slidably installed in the limiting seat 36. A rack 38 that meshes with the gear 37 is installed on the third moving frame 35. A threaded rod 39 is rotatably installed on the second support frame 30. The threaded rod 39 is threadedly connected to the third moving frame 35. A rocker arm 40 is installed on the exposed end of the threaded rod 39.

[0035] When the lifting platform 31 needs to be raised or lowered, the operator rotates the rocker arm 40 clockwise or counterclockwise. The rocker arm 40 drives the threaded rod 39 connected to it to rotate on the second support frame 30. Since the threaded rod 39 is threadedly connected to the third moving frame 35, and the third moving frame 35 is restricted to sliding in the limit seat 36, the rotational motion of the threaded rod 39 is converted into a stable horizontal linear motion of the third moving frame 35. The horizontal movement of the third moving frame 35 drives the rack 38 mounted on it to move synchronously, and the rack 38 drives it to mesh with the third moving frame 35. The gear 37 rotates and is fixedly mounted on the hinge shaft at the bottom of the fourth link 32. The rotation of the gear 37 causes the fourth link 32 to swing around its hinge point with the mounting base 34. The fourth link 32, through its hinge point with the fifth link 33 at its top, pushes the fifth link 33 to move. Since the fourth link 32 and the fifth link 33 together form a linkage mechanism connecting the mounting base 34 and the lifting platform 31, the movement of this mechanism ultimately transforms the rotational swing of the bottom of the fourth link 32 into a smooth vertical lifting motion of the lifting platform 31. By continuously rotating the rocker arm, the height of the lifting platform 31 can be precisely controlled, thereby adjusting the position of the bedpan it carries to coordinate with the opening and closing of the bed's drain opening, completing the receiving or removal operation.

[0036] As shown in Figure 10, the height adjustment mechanism includes a second drive component 20 installed below the base frame 16. A second movable frame 21 is mounted on the working end of the second drive component 20. A swing rod 19 is hinged to the second movable frame 21 and is hinged to the base frame 16. A support rod 18 is hinged above the swing rod 19 and is hinged to the bed frame 1. Specifically, the second drive component 20 can be an existing component such as an electric actuator, a cylinder, or a hydraulic cylinder.

[0037] When the overall height of the bed needs to be adjusted, the second drive unit 20 is activated, and its working end extends or retracts, directly driving the second movable frame 21 fixedly connected to it to move horizontally. The horizontal movement of the second movable frame 21 pushes the lower end of the swing rod 19 hinged to it. Since the middle part of the swing rod 19 is hinged to the base frame 16 (this hinge point constitutes the rotation fulcrum of the swing rod), when its lower end is pushed by the second movable frame 21, the entire swing rod 19 will rotate around the fulcrum. The rotation of the swing rod 19 causes the hinge point above it to produce an arc movement with the support rod 18. The lower end of the support rod 18 moves with this point, and its upper end is hinged to the bed frame 1. The support rod 18 converts the rotation of the swing rod 19 into a lifting or lowering force on the bed frame 1, thereby realizing the overall height adjustment of the bed frame 1 and its upper structure.

[0038] By controlling the stroke of the second drive component 20, the swing angle of the swing arm 19 can be changed precisely and smoothly, thereby steplessly adjusting the final working height of the bed to meet the needs of different care or usage scenarios.

[0039] As shown in Figures 11-13, a fixing plate 12 is connected to both the headboard 9 and the footboard 10. A third connecting rod 13 is hinged to the fixing plate 12. The guardrail 11 is hinged to the other end of the third connecting rod 13. A locking pin 15 is connected to the third connecting rod 13. A locking hook 14 matching the locking pin 15 is installed on the fixing plate 12.

[0040] When the protective function needs to be activated, the guardrail 11, which is in the retracted state, is lifted upwards. The rotation of the guardrail 11 is transmitted through the third link 13, which is hinged to it, causing the third link 13 to rotate synchronously around its hinge point with the fixed plate 12. When the guardrail 11 rotates to the set protective position, the locking pin 15 connected to the third link 13 engages precisely with the locking hook 14 installed on the fixed plate 12, achieving mechanical self-locking. At this time, the guardrail 11 is reliably fixed in the upright position, forming a safety barrier on the side.

[0041] When the guardrail needs to be retracted for easier getting in and out of bed or for nursing procedures, the operator first manually releases the locking hook 14 from the locking post 15. After releasing the lock, downward force is applied to the guardrail 11, causing it, along with the third link 13, to rotate in the opposite direction around the hinge point on the fixed plate 12 until the guardrail 11 smoothly flips downwards to fit against the side of the headboard 9 or footboard 10. In this state, the guardrail does not occupy extra space, and the mechanism returns to its standby state.

[0042] This guardrail mechanism achieves flipping through a connecting rod hinge and fixes its position using the cooperation of a locking hook and a locking post, thus allowing for safe and convenient switching between vertical protection and storage states. Its structure is simple and its operation is reliable.

[0043] A vital signs monitoring system, wherein the sensing elements are integrated into the bed or mattress system; the vital signs monitoring system includes: a weighing sensor integrated into the bed frame, a temperature and respiration sensing unit embedded in the mattress, and a data interface set in the bed for connecting electrocardiogram and blood oxygen monitoring probes.

[0044] The vital signs monitoring system achieves unobtrusive and continuous monitoring of vital signs while the patient is naturally lying down through integration and connection.

[0045] 1. Integrated Automated Monitoring Process: Weight Monitoring: Weighing sensors integrated into key support points of the bed frame operate continuously. After the patient lies down, the system automatically acquires and records their weight data, and can calculate the difference to monitor weight change trends, or trigger an alert to get out of bed when the weight suddenly drops.

[0046] Temperature and respiration monitoring: The temperature and respiration sensing units embedded in the mattress begin working as soon as the patient lies down; the temperature sensing element continuously monitors the body surface temperature, while the respiration sensing unit (usually using piezoelectric or fiber optic principles) continuously collects respiratory rate and rhythm signals by sensing the slight rise and fall of the chest and abdomen. This data is processed and analyzed in real time.

[0047] 2. Connectivity monitoring and data integration process: When more specialized cardiovascular function monitoring is required, medical staff can connect the standard electrocardiogram monitoring probe and blood oxygen saturation monitoring probe to the dedicated data interface set on the bed.

[0048] The electrocardiogram and blood oxygenation signals collected by the probe are transmitted to the system through a data interface.

[0049] The system synchronously collects, processes, and integrates multiple physiological parameters from integrated sensors (weight, body temperature, respiration) and external probes (ECG, blood oxygen) to form a unified vital signs monitoring dataset.

[0050] 3. Data Output and Application: All collected vital sign data are transmitted to the main controller for processing via internal system circuitry, and can be uploaded to the central monitoring system at the nurse station or mobile nursing terminal via wired or wireless means. The system can display waveforms and values ​​in real time, set safety thresholds for abnormal alarms, and store data for historical review and trend analysis, providing objective and continuous decision support for clinical nursing.

[0051] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
