Description

Technical Field

[0001] This invention relates to the field of medical transport flatbed technology, and more particularly to an intelligent medical transport flatbed. Background Technology

[0002] Intelligent medical transport carts are designed for use in hospitals, emergency centers, nursing homes, and other medical facilities. Applications include patient transport between operating rooms and wards, between internal medicine departments within a hospital, and during emergency medical transport. They are particularly suitable for transporting critically ill patients, elderly patients, and patients with limited mobility, aiming to improve the efficiency and safety of patient transport.

[0003] Most existing medical stretchers are manually operated, have limited functions, and lack intelligent control and management, failing to meet the current needs of clinical patient transport. In situations of insufficient medical staff, patient transport faces certain limitations (intelligent transport). When transporting patients, medical staff need to manually adjust the height and angle of the stretcher, which is cumbersome, poses safety hazards, and is laborious (automatic movement), causing discomfort to the patient. Furthermore, traditional stretchers lack wind and rain protection, limiting transport in inclement weather or infectious environments, such as increasing the risk of patient exposure and healthcare worker infection. Traditional stretchers also lack oxygen storage devices, posing a safety hazard. In addition, traditional stretchers lack vital sign monitoring devices, making it impossible to monitor patients' vital signs in real time, hindering emergency response and delaying crucial treatment time. Traditional stretchers with standard IV stands require manual installation and removal, are inconvenient to secure, and are prone to wobbling, presenting limitations. Moreover, traditional stretchers lack insulation functions (medical intelligent temperature-controlled mattresses), often causing patients to feel cold during their return to the ward after general anesthesia, leading to discomfort. The lack of drainage hooks means drainage bags are often left haphazardly, failing to provide effective drainage. The absence of lighting during nighttime patient transport poses a safety hazard. The location of unused stretchers in the operating room is unclear, requiring phone calls to inquire about their location, hindering effective positioning (location system) and wasting medical staff's time. The scanning and camera function can verify patient information by scanning wristbands, improving transport accuracy and preventing errors. The camera can record the transport process, reducing medical disputes. The intelligent voice system is more user-friendly, providing education, comfort, and reminders, making it more patient-friendly and simplifying procedures for medical staff; simple conversations are all that's needed to issue commands. This intelligent medical transport stretcher can be operated by one person, reducing the burden on medical staff and providing patients with a more comfortable and convenient transport service. Therefore, this device provides an intelligent medical transport stretcher. Summary of the Invention

[0014] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0015] Firstly, the medical transport trolley provides patients with a flat transport space; the height adjustment device can be adapted to beds and examination tables of different heights, making it convenient for patients to get on and off and for equipment to be connected; the angle adjustment device can adjust the tilt angle of the trolley to meet the needs of special patients, such as preventing choking and relieving breathing difficulties, thereby improving the comfort and safety of transport.

[0016] Secondly, the infusion support device is located at the front of the flatbed, which can securely suspend the infusion bottle or bag, ensuring that the tubing does not become tangled or fall off during the infusion process. It also has functions such as infusion rate monitoring to ensure the smooth progress of the patient's infusion treatment. The protective device can effectively protect the patient's privacy and avoid the patient's exposure during transportation; it can also prevent the patient from accidentally falling or colliding, playing a safety protection role, especially suitable for patients with impaired consciousness or limited mobility. The wrist intelligent detection device can collect the patient's vital signs data in real time, such as heart rate, blood pressure, and blood oxygen saturation, to help medical staff keep track of the patient's health status at any time, detect abnormalities in a timely manner and deal with them, and provide data support for medical decisions during transportation.

[0017] Thirdly, the intelligent system of this device serves as the core hub, integrating the functions of various devices to achieve automated and intelligent control. For example, it can automatically adjust the height and angle of the flatbed, monitor the infusion status, and receive and analyze data from wrist detection devices. It can also interface with the hospital information system, facilitating medical staff to track the transfer progress and patient information in real time, thereby improving the efficiency and management level of the medical process. As the "brain" of the intelligent medical transport flatbed, the intelligent system 7 achieves intelligent management and efficient collaboration of the equipment through the integration of multiple technologies, providing comprehensive protection for the patient transfer process.

[0018] Fourth, during patient treatment, in order to enable patients to receive better treatment, the angle of the front bed board can be adjusted according to the actual treatment situation and the patient's comfortable position during rest. The angle adjustment function of the head end of the bed (usually in the direction of the patient's head) is an important design of intelligent medical transport trolley, which is the position of the front bed board described in this device. By changing the tilt angle of the head end of the bed (such as raising or lowering), the positional needs of different patients can be met, assisting in treatment and nursing operations.

[0019] Fifth, when the patient needs to be covered by the protective cover, the two protective motors run synchronously, driving the corresponding rotating shaft on the output end of the corresponding protective motor to rotate. The rotation of the corresponding rotating shaft drives the corresponding protective clamp to rotate, and the rotation of the corresponding protective clamp drives the corresponding protective rod to rotate, thereby driving the corresponding protective shaft to rotate, and finally driving the protective cover to cover or fold and store.

[0070] Preferably, the height adjustment device 2 includes a height adjustment cylinder 21, a telescopic rod 22, a moving rod 23, height adjustment blocks 24, height adjustment plates 25, and a support fixing plate 26. The height adjustment cylinder 21 is located at the lower end of the base 11. The telescopic rod 22 is located at the output end of the height adjustment cylinder 21. The moving rod 23 is located at the lower end of the base 11 and is configured to slide left and right. The end of the telescopic rod 22 is connected to the moving rod 23 and is hinged. The moving rod 23 is I-shaped. There are four height adjustment blocks 24, which are respectively located at the four ends of the moving rod 23. There are four height adjustment plates 25, which are respectively located on the corresponding height adjustment blocks 24 and are all rotatably connected. The support fixing plate 26 is square, and the four corners of the support fixing plate 26 are respectively fixed to the upper end of the lead screw height adjustment plate 25. The support fixing plate 26 is fixedly connected to the lower end of the bed frame 12.

[0071] Due to the varying heights of operating tables, emergency resuscitation beds, imaging equipment (such as CT / MRI beds), and ward beds, this device needs to be adjusted to a suitable height to better facilitate patient treatment. This ensures the medical transport trolley 1 is at the same height as the target medical equipment, avoiding secondary handling or jolting during patient transfer due to height differences. This is particularly suitable for scenarios requiring stable transfer, such as for critically ill or post-operative patients. When the height of the bed 13 needs adjustment, it is driven by a remote control or voice-activated intelligent adjustment to operate the height adjustment cylinder 21. The operation of the height adjustment cylinder 21 moves the telescopic rod 22 at its output end forward. The telescopic rod 22's extension and retraction movement drives the moving rod 23 forward, thereby moving several height adjustment blocks 2. 4. Moving forward changes the height of the upper part of several height adjustment blocks 24. After the height of the several height adjustment blocks 24 is adjusted, the corresponding height adjustment plate 25 will be adjusted. The height adjustment of the several height adjustment plates 25 will be adjusted, and the height of the support fixing plate 26 will be adjusted. Ultimately, the height of the bed frame 12 and the bed body 13 are adjusted to adapt to the different heights of operating tables, emergency resuscitation beds, imaging examination equipment (such as CT / MRI beds), and ward beds, so as to better facilitate the treatment of patients. According to the height of medical staff (such as the different operating habits of nurses and doctors), the bed body 13 can be adjusted to a comfortable operating height (such as 60-90cm), which can reduce the physical consumption caused by bending over and raising arms, and reduce the risk of occupational injury.

[0072] Preferably, the angle adjustment device 3 includes an angle adjustment cylinder 31, an angle adjustment frame 32, an angle adjustment shaft 33, and a connecting block 34. The angle adjustment cylinder 31 is disposed at the lower end of the tailstock plate 17. The angle adjustment frame 32 is disposed at the lower end of the tailstock plate 17 and is located beside the angle adjustment cylinder 31. The angle adjustment shaft 33 is disposed on the output end of the angle adjustment cylinder 31. The middle part of the connecting block 34 is rotatably connected to the angle adjustment frame 32. The end of the angle adjustment shaft 33 is disposed at the lower end of the connecting block 34 and is rotatably connected. The upper end of the connecting block 34 is rotatably connected to the lower end of the front bed plate 16.

[0073] During patient treatment, to ensure better care, the angle of the front bed board 16 can be adjusted according to the patient's actual treatment situation and comfortable resting position. The angle adjustment function of the head end of the bed 13 (usually in the direction of the patient's head) is a crucial design feature of intelligent medical transport trolleys. This refers to the position of the front bed board 16 described in this device. By changing the tilt angle of the head end of the bed 13 (e.g., raising or lowering it), the positioning needs of different patients can be met, assisting in treatment and nursing procedures. When adjusting the angle of the front bed board 16, the activation of the angle adjustment cylinder 31 first drives the angle adjustment shaft 33 on the output end of the cylinder 31 to move forward on the angle adjustment frame 32. The forward movement of the angle adjustment shaft 33 drives the connecting block 34 to adjust its angle, thereby causing the front bed board 16 to adjust its angle. The adjustable headboard allows for 16-degree angle adjustment to a suitable position, relieving breathing difficulties for patients with chronic obstructive pulmonary disease (COPD) and those experiencing acute asthma exacerbations. Raising the head of the bed to 30°-45° (semi-recumbent position) reduces pressure on the lungs from abdominal organs, expands the thoracic cavity, promotes diaphragmatic movement, increases vital capacity, and reduces the risk of pulmonary complications such as atelectasis and hypostatic pneumonia. A bed height of 13-15°-30° (modified shock position) promotes venous return to the brain, reduces intracranial pressure, and is suitable for patients with cerebral hemorrhage and cerebral edema. When the head of the bed is raised to 45°-60°, the patient is in a semi-recumbent position, facilitating oral care, suctioning, and endotracheal intubation, reducing the difficulty and physical exertion of these procedures. The angle can be adjusted according to the patient's preference (e.g., some patients prefer a slight 20° elevation) to avoid back pain and pressure sores on the back caused by prolonged lying flat.

[0074] Preferably, the infusion auxiliary device 4 includes an infusion auxiliary block 41, a screw 42, a nut 43, an infusion rod 44, an auxiliary rod 45, an auxiliary knob 46, an infusion stand 47, and infusion hooks 48. The infusion auxiliary block 41 is mounted on the baffle 15. The screw 42 is mounted on the infusion auxiliary block 41 and its end passes through the infusion auxiliary block 41. The nut 43 is sleeved on the end of the screw 42. The end of the infusion rod 44 is sleeved on the screw 42. The auxiliary rod 45 is located inside the infusion rod 44 and is slidably fitted. The end of the auxiliary knob 46 passes through the infusion rod 44 and is located inside it, abutting against the auxiliary rod 45. The auxiliary stand is mounted on the auxiliary rod 45. The infusion stand 47 is provided with a plurality of infusion slots 49, which are arranged equidistantly around each other. A plurality of infusion hooks 48 are provided, and each of the plurality of infusion hooks 48 is respectively located in a corresponding infusion slot 49.

[0075] Intravenous infusion is an essential part of patient treatment. Due to the different medications used, the height of the infusion bag can be adjusted according to the characteristics of the solution to achieve better treatment results. [For example, when mannitol requires rapid infusion, the infusion bag can be suspended at a height of over 1.8 meters to increase the drip rate using gravity]. However, for neonatal infusions, the height should be lowered to 0.8 meters to avoid damage to blood vessels due to excessive hydrostatic pressure. During blood transfusions, the infusion bag height should be maintained at 1.2-1.5 meters to balance the drip rate and safety. Adjusting the height of the infusion rod 44 is also essential during intravenous infusion. When adjusting the height of the infusion stand 47, first adjust the end of the screw 42... Rotate nut 43 to loosen screw 42, then rotate infusion rod 44 to place it in a vertical position. Next, rotate nut 43 again to lock screw 42 back in place. At this point, the height of infusion stand 47 can be adjusted according to the required treatment height. First, rotate auxiliary knob 46 so that the end of auxiliary knob 46 disengages from the surface of auxiliary rod 45. Then, pull auxiliary rod 45 up or down to adjust the height of infusion stand 47. After the height of infusion stand 47 is adjusted, rotate auxiliary knob 46 again so that the end of auxiliary knob 46 abuts back against the surface of auxiliary rod 45 to limit the position.

[0076] Preferably, the protective device 5 includes a protective motor 51, a rotating shaft 52, a protective clamp 53, a protective block 54, a protective rod 55, a protective shaft 56, and a protective cover 57. Two protective motors 51 are provided, symmetrically arranged at the lower end of the tailstock plate 17. Two rotating shafts 52 are provided, each connected to the output end of a corresponding protective motor 51. Two protective clamps 53 are provided, each mounted on a corresponding rotating shaft 52. Two protective blocks 54 are provided, symmetrically arranged on both sides of the tailstock plate 17. A plurality of protective shafts 56 are provided, divided into two groups, with the two groups being opposite to each other. The protective shafts 56 are connected in a gradually decreasing and stacked manner, and each adjacent protective shaft 56 is rotatably connected. Several protective rods 55 are provided, each set on a corresponding protective shaft 56. Two protective clamps 53 are each provided with a clamping groove, which clamps onto the corresponding protective rod 55. The two ends of the protective cover 57 are connected to the corresponding protective rods 55. The protective cover 57 is made of sterile and epidemic-proof material. The protective cover 57 is folded in its retracted state and covers the entire surface when unfolded. The outer surface of the protective cover 57 is a TPU waterproof membrane, and the inner layer is silver ion antibacterial fiber.

[0077] When a patient needs to be covered by the protective cover 57, the two protective motors 51 operate synchronously, driving the corresponding rotating shaft 52 at the output end of the corresponding protective motor 51 to rotate. The rotation of the corresponding rotating shaft 52 drives the corresponding protective clamp 53 to rotate, which in turn drives the corresponding protective rod 55 to rotate, thereby driving the corresponding protective shaft 56 to rotate, ultimately causing the protective cover 57 to either cover the patient or fold it for storage.

[0078] This device features highly efficient automated protection: the protective motor 51 drives the rotating shaft 52, which in turn drives the protective clamp 53, protective rod 55, and protective cover 57 to automatically unfold and retract. Medical staff only need to activate the motor to quickly switch the protective cover 57 from folded to fully covered state. Compared to manually setting up a protective barrier, this significantly improves operational efficiency, making it particularly suitable for emergency transport or the transport of infectious disease patients. It rapidly creates an isolation space, reducing the risk of virus transmission. During patient rest or treatment, the protective cover 57 can be unfolded at any time to cover the patient, quickly establishing an isolation space. For infectious disease patients, it effectively blocks droplet and aerosol transmission, preventing virus spread and protecting medical staff and the surrounding environment. For patients with weakened immune systems, such as post-operative or chemotherapy patients, it isolates external pathogens, reducing the risk of cross-infection. When protection is not needed, the protective cover 57 can be easily folded away, without occupying extra space or affecting the normal operation of medical staff or patient activities, meeting dynamic protection needs in different scenarios.

[0079] With tight isolation and protection: The protective cover 57 is made of sterile and epidemic prevention materials. The outer TPU waterproof membrane can effectively block the penetration of contaminants such as droplets and bodily fluids, preventing the leakage or invasion of pathogens such as viruses and bacteria. The inner silver ion antibacterial fiber can actively inhibit bacterial growth, reduce the risk of infection for patients, and at the same time ensure the safety of medical staff and the surrounding environment. It builds a reliable physical and biological protective barrier for the transportation process. For agitated or unconscious patients, the protective cover 57 can serve as a physical protective barrier to prevent patients from accidentally falling off the bed or getting injured by collision, thus playing a safety protection role. During treatment, it can also prevent patients from unconsciously touching treatment equipment and tubing, ensuring the smooth progress of treatment.

[0080] With flexible adaptability and stable support: Several protective shafts 56 are stacked in a gradually decreasing size and rotated connection, giving the protective device 5 good flexibility and adaptability. When deployed, the coverage area and shape of the protective cover 57 can be flexibly adjusted according to the patient's body size, bed size and transportation needs; the protective block 54 and protective clamp 53 work together to provide stable support for the protective shafts 56 and protective rods 55, ensuring that the protective cover 57 is stable and does not shake during transportation, and continues to play a protective role.

[0081] It is easy to store and reuse: the protective cover 57 can be folded and retracted when not in use, taking up little space and easy to store without affecting the normal use and transfer of the hospital bed; at the same time, its material is durable and easy to clean and disinfect, and can be reused, reducing medical costs and meeting the needs of hospital infection control and efficient use of resources.

[0082] Reducing medical costs and infection risks: The reusable protective shield 57 lowers the cost of medical consumables compared to disposable protective equipment; its convenient folding and storage design reduces storage and management costs. Simultaneously, through effective isolation and protection, it significantly reduces the probability of patient infection, shortens hospital stays, and reduces subsequent treatment costs; it also reduces the occupational exposure risk for healthcare workers, reduces the consumption of medical resources due to infection, and thus reduces overall medical costs and improves the efficiency of medical resource utilization from multiple perspectives.

[0083] Versatile and adaptable to various scenarios: Whether it's preventing cross-infection during the transport of ordinary patients, or providing enhanced protection during the transport of patients with infectious diseases or those with weakened immune systems after surgery, this device is capable of handling the task. With its automated deployment, tight protection, flexible adjustment, and easy storage, it adapts to different medical transport scenarios, providing comprehensive safety for patients and medical staff.

[0084] Preferably, the bed also includes a safety railing 8 to prevent the patient from falling. There are two safety railings 8, which are symmetrically arranged on both sides of the bed 13. Both safety railings 8 are set by a snap-fit ​​method and can be lowered or upright for protection.

[0085] The two guardrails are mainly used to prevent patients from falling out of bed, assist in getting up / turning over, stabilize body posture, and protect tubing safety. Their functional design is closely centered on the safety, comfort, and convenience of medical and nursing operations during patient transfer.

[0086] The two guardrails are typically 30-50 cm high [adjustable according to the patient's body size]. When raised, they form a vertical barrier to prevent the patient from accidentally falling when unconscious, agitated, or turning over [especially suitable for comatose, Alzheimer's disease, and postoperative anesthesia patients].

[0087] Both protective railings are made of soft-covered materials (such as sponge + waterproof PU leather) to prevent secondary injuries from hard impacts (such as when agitated patients struggle and hit the railings). They feature quick locking and releasing: both railings have double-buckle locking devices at the bottom, allowing for quick raising or lowering with a single hand press (operation time < 3 seconds). In emergencies (such as when exposing the patient's chest and abdomen during CPR), they can be completely disassembled with a single button. The outer sides of both railings have multi-position tube clamps (5-10 cm adjustable spacing) to secure IV lines, urinary catheters, and gastric tubes, preventing tangling or dragging (such as when the patient turns over and the tubes become caught on the railings and dislodged). These two protective railings may seem like simple accessories on a hospital bed, but they are actually multi-dimensional guardians ensuring patient safety during transport. Its core value, through a triple design of "physical protection + functional expansion + intelligent linkage," not only solves the single-function limitation of traditional guardrails that "only prevent falls from beds," but also, through scenario-based adaptation (such as pediatric collision prevention, critical patient positioning support, and infectious disease isolation) and intelligent upgrades (such as pressure alarms and pipeline management), it becomes a dual core component of intelligent medical transport flatbeds, serving as both a "safety defense" and a "treatment assistance." In the future, with the aging society and the increasing demand for precision medicine, the guardrail design will place greater emphasis on ergonomics (such as lightweight materials and adaptive height) and humanistic care (such as anti-fear visual design), further enhancing patient experience and medical safety.

[0136] The two safety belts 10 installed on the bed frame 13 [usually equipped on medical beds or special function beds] are mainly used to fix the patient's body and prevent accidental risks caused by changes in body position, loss of consciousness, or treatment needs. The safety belts 10 fix the patient's torso or limbs to the bed frame 13 [such as one for the shoulder and one for the hip], restricting their voluntary or involuntary rolling or sitting-up movements, and avoiding secondary injuries such as fractures and traumatic brain injury from falling off the bed. For ICU patients who become agitated due to discomfort from endotracheal intubation, the use of safety belts 10 in conjunction with sedation can reduce the risk of extubation. Patients with epileptic seizures are fixed during convulsions, which can reduce the risk of injury from the body hitting the bed rails.

[0139] Data Acquisition Layer: Integrates a smart wrist detection device 6, angle sensor, height sensor, infusion monitoring module, etc., to collect multi-source data such as patient vital signs, stretcher posture, and infusion flow rate in real time. For example, a pressure sensor monitors pressure changes in the stretcher height adjustment device 2 to precisely control the lifting height; a photoelectric sensor monitors the fluid flow rate in the infusion tubing in real time to ensure infusion safety.

[0140] Data processing layer: Equipped with a high-performance processor and edge computing module, it performs real-time analysis and processing of collected data. Machine learning algorithms are used to model patient vital sign data and predict disease progression trends; PID control algorithms are employed to precisely adjust the height and angle of the pallet cart, ensuring stability and accuracy.

[0141] Communication Interaction Layer: Supports multiple communication protocols such as 5G, Wi-Fi, and Bluetooth, enabling seamless connection with the Hospital Information System (HIS) and handheld terminals for medical staff. It synchronizes patient transfer information and real-time monitoring data to the hospital database, facilitating remote viewing and management by medical staff; it also receives control commands from terminals to remotely operate various functions of the trolley.

[0142] Core Functions

[0143] Automated control: Based on preset programs or instructions from medical staff, the height adjustment device 2 and angle adjustment device 3 are automatically controlled to operate. For example, when transferring the patient to the operating room, the height of the stretcher is automatically adjusted to be level with the operating table; the angle of the stretcher is automatically adjusted according to the patient's condition to provide a comfortable position for the patient.

[0144] Intelligent monitoring and early warning: Continuously monitors patient vital signs, infusion status, and stretcher operation parameters. Once the data exceeds preset thresholds, it immediately issues early warnings to medical staff through audible and visual alarms and push notifications. For example, when an abnormally high heart rate or an infusion rate that is too fast / too slow is detected, medical staff are promptly alerted to take appropriate action.

[0145] Route planning and navigation: Combining GPS positioning system and hospital map data, it plans the optimal route for transport flatcars, avoiding congested areas and obstacles; it provides navigation guidance to medical staff via voice or display screen, improving transport efficiency. Simultaneously, it can collaborate with the hospital's intelligent logistics system to automatically avoid moving equipment such as logistics robots.

[0146] Equipment Status Management: Real-time monitoring of the operational status of various components of the flatbed cart, such as battery level, braking system, and shock absorption system, to predict equipment failures and issue maintenance reminders in advance, ensuring the normal operation of the flatbed cart. For example, when the charging device's battery level is detected to be below 20%, medical staff are reminded to charge it in time; when an abnormality is detected in the braking system, the flatbed cart is prohibited from moving and an alarm is issued.

[0147] Application advantages

[0148] Enhancing medical safety: Real-time monitoring and early warning functions reduce the risks to patients during transport; automated control ensures the accuracy of stretcher operation and avoids harm to patients due to human error.
