Description

Technical Field

[0001] This invention relates to the field of mattress technology, specifically to a patient body shape adjustment mattress for ultrasonic medical examinations. Background Technology

[0002] Ultrasound medical examinations, with their advantages of being non-invasive, radiation-free, and providing real-time imaging, have been widely used in various clinical departments, including abdominal, cardiovascular, obstetrics and gynecology, and musculoskeletal departments. The accuracy of the examination results is highly dependent on the stability and suitability of the patient's position—it is necessary to ensure that the examination site is fully exposed, the probe is in close contact with the skin, and the patient's body is not excessively stretched or compressed, so as to avoid image artifacts, missed diagnoses, or misdiagnoses caused by improper positioning.

[0003] However, most ultrasound examination mattresses currently used in clinical practice are traditional fixed structures that only provide basic support. In ultrasound examinations, existing examination beds generally suffer from being too hard and lacking sufficient body adjustment capabilities: Firstly, for patients with lumbar or limb fractures, a hard bed can easily cause secondary pressure, and patients cannot adjust their position independently, making it difficult for them to cooperate with the examination; secondly, for patients with sequelae of stroke or elderly patients with limited mobility, their limited physical activity makes it difficult for them to flexibly turn to their side or maintain a suitable position, resulting in poor compatibility between the ultrasound probe and the examination site, which seriously affects the accuracy of the examination measurement results and consequently has an adverse impact on subsequent diagnosis and treatment.

[0004] With the increasing demands for precision in clinical ultrasound examinations and the growing need for more comfortable medical care, traditional fixed mattresses can no longer meet the needs of diverse diagnostic and treatment scenarios. Therefore, there is an urgent need for a device that can help special patients adjust their body shape and improve the adaptability of ultrasound examinations. Summary of the Invention

[0038] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0039] Example 1

[0040] like Figure 1 and Figure 4As shown, a patient body-adjusting mattress for ultrasound medical examination includes a bed frame 1, a mattress body 2, electric actuators 4, adjusting airbags 3, air ducts 5, and an air pump 6. The bed frame 1 supports all components, facilitating stable use of the entire mattress. The bed frame 1 is connected to the support structure of the examination bed, ensuring a stable connection between the mattress and the mattress. The mattress body 2 has, from back to front, a calf adjustment area 01, a thigh adjustment area 02, a lumbar adjustment area 03, a side-lying adjustment area 04, and a neck adjustment area 05. These areas are used to adjust the calves, thighs, waist, side-lying, and neck respectively, thereby assisting medical personnel in conducting efficient examinations of the patient's body. Multiple electric actuators 4 are provided, and they are located at the bottom of the calf adjustment area 01 and the thigh adjustment area 02. The electric actuators 4 are fixed to the bed frame 1 and are used to move the calf adjustment area 01 and the thigh adjustment area 02 up and down, thus facilitating the up and down adjustment of the mattress in these areas and assisting the patient in adjusting their body position. Multiple adjustable airbags 3 are provided. The airbags are designed to facilitate the adjustment of the patient's position by inflating and deflating them. The multiple adjustable airbags 3 are respectively located on the lumbar adjustment area 03, the lateral adjustment area 04, and the neck adjustment area 05. The patient's lumbar, lateral, and neck positions can be adjusted by inflating and deflating the adjustable airbags 3, which facilitates medical staff to conduct rapid examinations on the patient. The air duct 5 is located under the bed frame 1 and is connected to multiple adjustable airbags 3. The air duct 5 can control the inflation and deflation of each airbag. The exhaust end of the air pump 6 is connected to the air inlet of the air duct 5 and is used to inflate the adjustable airbags 3, which facilitates the adjustment of the patient's position and examinations by inflating the adjustable airbags 3.

[0041] like Figure 2 and Figure 3As shown, the upper surface of the bed frame 1 has a placement groove 10 for placing the mattress body 2, ensuring that the mattress body 2 is stable on the top of the bed frame 1, and facilitating stable support of the patient's body. A support frame 11 is provided along the bottom of the placement groove 10 on the bed frame 1, which supports the mattress body 2 and ensures stable placement. The support frame 11 has limiting grooves 12 aligned with the lower leg adjustment area 01 and the thigh adjustment area 02 at the rear end of the mattress body 2 to prevent interference between the mattress body 2 and the bed frame 1. A mounting plate 13 is provided at the rear bottom of the bed frame 1, aligned with the electric push rod 4. The mounting plate 13 has a mounting hole 131 in the middle, which facilitates the installation and stable use of the electric push rod 4. The mounting hole 131 allows the output end of the electric push rod 4 to pass through the mounting plate 13, thus facilitating the electric push rod 4 to adjust the mattress in the lower leg adjustment area 01 and the thigh adjustment area 02 vertically. A through hole 15 is provided near the front end of the bed frame 1; the through hole 15 is to prevent interference between the adjustable airbag 3 and the bed frame 1. A first junction box 14 is provided near the rear end of the bottom of the bed frame 1. The first junction box 14 facilitates simultaneous connection to multiple electric actuators 4, ensuring the stability of the electric actuators 4. Multiple connecting slots 141 are provided on the side of the first junction box 14, facilitating connection between the first junction box 14 and the electric actuators 4. A first wire 142 is provided on the first junction box 14, and a first connector 143 is provided at the end of the first wire 142. The first wire 142 and the first connector 143 facilitate power connection, thereby controlling the operation of the electric actuators 4.

[0042] like Figure 4 As shown, the bottom of the mattress body 2 is equipped with a reinforcing edging 24 to ensure the strength of the bottom of the mattress body 2 and to ensure that the mattress body 2 is stably placed inside the placement slot 10. The calf adjustment area 01 and the thigh adjustment area 02 are separated from the mattress body 2, facilitating the electric push rod 4 to adjust the calf adjustment area 01 and the thigh adjustment area 02 up and down. The bottom surface of the calf adjustment area 01 and the thigh adjustment area 02 is equipped with a support plate 21, which reinforces the bottom of the calf adjustment area 01 and the thigh adjustment area 02, preventing the electric push rod 4 from moving the calf adjustment area 01 and the thigh adjustment area 02 up and down, thus facilitating adjustment of the patient's calves and thighs. The lumbar adjustment area 03 has multiple horizontally arranged... The side-body adjustment area 04 has multiple mounting slots 22 along the edge of the mattress body 2. One of the mounting slots 22 in the lumbar adjustment area 03 and the side-body adjustment area 04 is shared. The neck adjustment area 05 has a mounting slot 22. The bottom surface of the mounting slot 22 has a perforation 23. The mounting slot 22 facilitates the installation of the adjustment airbag 3, which allows for easy adjustment of the patient's position. The perforation 23 allows the bottom of the adjustment airbag 3 to pass through the mattress body 2, facilitating the use of the entire mattress body 2.

[0043] like Figure 5As shown, the mattress body 2 has a three-layer composite structure, consisting of an elastic support layer 201, a breathable cushioning layer 202, and an antibacterial and skin-friendly layer 203 from the inside out. The antibacterial and skin-friendly layer 203 uses medical-grade silicone material containing silver ions, effectively improving the antibacterial effect of the mattress body 2. The breathable cushioning layer 202 adopts a 3D three-dimensional woven structure, enhancing the overall comfort of the mattress body 2 and making it more comfortable for patients to lie on the examination bed. The mattress body 2 integrates flexible heating wires and temperature sensors, enabling temperature adjustment within the range of 32-38℃ and featuring overheat protection. After the user sets the target temperature via the control terminal, the internal MCU controls the relay. The flexible heating wire converts electrical energy into heat energy according to Joule's law, gradually increasing the mattress temperature. Simultaneously, the NTC temperature sensor (with negative temperature coefficient) attached to the mattress body 2 converts temperature changes into resistance-voltage signals, which are transmitted to the MCU in real time. The MCU dynamically controls the heating wire's on / off state by comparing the "actual temperature" with the "set temperature"—heating continues when the temperature is below 32℃, and power is cut off when the target temperature is reached (32-38℃ is the comfortable range for human sleep, balancing warmth and deep sleep needs). It restarts when the temperature drops to the lower limit, forming a closed-loop regulation to maintain temperature stability. If abnormal overheating occurs (such as exceeding 40℃ or heating timeout), the MCU will trigger a software-level emergency power-off. If the fault still exists, the temperature fuse (hardware level) connected in series in the heating circuit will cut off the circuit due to the melting of the alloy sheet. This double protection avoids the risk of burns or fire, ultimately achieving a balance between comfortable temperature control and safety.

[0044] like Figure 6 As shown, the adjustable airbag 3 is folded and positioned inside the mounting slot 22, ensuring its stability within the mattress body 2. A support base plate 31 is located at the bottom of the adjustable airbag 3, ensuring sufficient stability.

The bottom end of the connecting tube 32 passes through a perforation 23 and protrudes from the bottom of the bed frame 1. The connecting tube 32 facilitates connection to the air guide tube 5, allowing for easy air supply to the adjustable airbag 3. A pressure cap 33 is provided on the connecting tube 32, pressing it firmly against the bed frame 1 to ensure the adjustable airbag 3 remains stable within the mounting slot 22, facilitating stable use and retraction of the adjustable airbag 3.

[0045] like Figure 7As shown, the electric actuator 4 has a connecting wire 41 on its side, and a connecting plug 42 at the end of the connecting wire 41. The connecting wire 41 and the connecting plug 42 facilitate electrical connection between the electric actuator 4 and the first junction box 14, making it convenient to use the electric actuator 4. The top of both sides of the electric actuator 4 has a fixing plate 43 with multiple fixing holes 44, allowing the electric actuator 4 to be fixed to the mounting plate 13 by bolts passing through the fixing holes 44. The output end of the electric actuator 4 has a telescopic rod 45, which facilitates height adjustment of the mattress in the calf adjustment area 01 and the thigh adjustment area 02. The top of the telescopic rod 45 has a connecting plate 46 with multiple connecting holes 47 on its edge. The connecting plate 46 is fixed to the support plate 21 by bolts passing through the connecting holes 47, ensuring a stable connection between the output end of the electric actuator 4 and the mattress in the calf adjustment area 01 and the thigh adjustment area 02.

[0046] like Figure 8 As shown, the air duct 5 has multiple branch pipes 51, which facilitate the inflation of each regulating airbag 3. Each branch pipe 51 is equipped with a three-way solenoid valve 52, which is connected to the side of the branch pipe 51. The bottom of the three-way solenoid valve 52 is the exhaust end, which facilitates the discharge of gas from the airbags, thus controlling the inflation and deflation of the regulating airbags 3. The top of the three-way solenoid valve 52 has an external connecting pipe 54, and the top of the external connecting pipe 54 has a connecting cap 55. The connecting cap 55 is connected to the bottom of the connecting pipe 32. The cooperation between the external connecting pipe 54 and the connecting cap 55 facilitates the connection between the three-way solenoid valve 52 and the connecting pipe 32 of the regulating airbag 3. Multiple actuators 53 are located on the side of the three-way solenoid valve 52 for controlling its opening and closing.

[0047] like Figure 9 As shown, the air pump 6 has a support foot 61 at its bottom side, with multiple bolt holes 62. The support foot 61, in conjunction with the bolt holes 62, facilitates the fixing of the air pump 6 to a stable position using bolts. The air pump 6 has a second junction box 63 at its top, with a second wire 64 at one end and a second connector 65 at the other. The junction box 63, wire 64, and connector 65 facilitate power connection to the air pump 6, making its operation and use easier. The air pump 6 has an exhaust pipe 66 at its exhaust end, with an adapter cap 67 at its top. The exhaust pipe 66 and adapter cap 67 facilitate connection to the connecting pipe 32 of the regulating air bag 3, allowing for air supply to the regulating air bag 3. The air pump 6 has an intake port 68 at its intake end, with a filter element 69 at the intake port 68 for filtering dust from the air.

[0057] like Figure 1As shown, the system also includes a control box 7, which is installed at the bottom of the bed frame 1. The control box 7 is electrically connected to the three-way solenoid valve 52, the air pump 6, the electric push rod 4, and the mattress body 2. It is used to control the operation of each component, facilitating the use of the entire mattress and allowing for easy control of the operation of each component through the control box 7, thereby enabling adjustment and use of the patient's position. Furthermore, the bottom of the control box 7 has a power connection slot for connecting to a power supply line, facilitating the operation of the entire device.

[0058] like Figure 10 As shown, the control box 7 has a display screen 71 on its front, which displays operation data for easy viewing. Below the display screen 71 on the front of the control box 7 is a control panel 72, which allows for easy control of the entire mattress and thus convenient control of each adjustment zone.

A positioning plate 74 is located at the top of the back of the control box 7, with multiple positioning holes 75. The positioning plate 74 is fixed to the bottom of the bed frame 1 by bolts passing through the positioning holes 75, ensuring the stability of the control box 7 at the bottom of the bed frame 1 and facilitating its use. The control box 7 contains an MCU controlling relays for controlling the flexible heating wires.

[0059] Working Principle: This ultrasound medical examination patient body adjustment mattress uses a control box 7 as its central control core. It achieves its functions by coordinating and controlling the body position adjustment system and the temperature control system. The specific working principle is as follows: The control box 7 is installed at the bottom of the bed frame 1 and is electrically connected to the three-way solenoid valve 52, air pump 6, electric push rod 4, and mattress body 2. It can receive operating commands and control the operation of each component. Its bottom power socket is connected to the power supply line to power the entire device. Regarding body position adjustment, for the lower leg adjustment area 01 and the thigh adjustment area 02, the electric push rod 4 is fixed through the bed frame 1 mounting plate 13. Its top is connected to the support plate 21 at the bottom of the adjustment area via a connecting plate 46. The control box 7 controls the extension and retraction of the extension rod 45 of the electric push rod 4 through the first junction box 14, thereby moving these two adjustment areas up and down to adjust the patient's lower leg and thigh position. For the lumbar adjustment area 03, the side-lying adjustment area 04, and the neck adjustment area 05, each adjustment area has an adjustment airbag in its mounting slot 22. 3. The exhaust end of the air pump 6 is connected to the air guide tube 5 via the exhaust pipe 66 and the adapter cap 67. The branch pipe 51 of the air guide tube 5 is connected to the connecting pipe 32 of the air bag via the three-way solenoid valve 52, the external pipe 54 and the connecting cap 55. The control box 7 controls the air pump 6 to start and inflate the air bag. Controlling the three-way solenoid valve 52 can deflate the air bag. By adjusting the inflation and deflation of each air bag individually, the patient's waist, side and neck position can be accurately adjusted. The structural design of the bed frame 1 and the mattress body 2 ensures the stable operation of each adjustment component. In terms of temperature regulation, the flexible heating wire integrated inside the mattress body 2 works in conjunction with the NTC temperature sensor. After the user sets the target temperature within the range of 32-38℃ through the control box 7, the MCU controls the relay to energize the heating wire and generate heat according to Joule's law. At the same time, the NTC temperature sensor converts the real-time temperature into a resistance-voltage signal and transmits it to the MCU. The MCU compares the actual temperature with the set temperature. If the temperature is below 32℃, it continues to heat; if the target temperature is reached, it cuts off the power; and if the temperature drops to the lower limit, it restarts, forming a closed-loop regulation to maintain temperature stability. If abnormal overheating occurs, such as exceeding 40℃ or heating timeout, the MCU first triggers a software-level emergency power-off. If the fault is not eliminated, the temperature fuse (hardware level) connected in series in the heating circuit melts and cuts off the circuit, achieving dual overheat protection. At the same time, the antibacterial skin-friendly layer 203, the breathable cushioning layer 202, and the elastic support layer 201 on the surface of the mattress body 2 also provide a comfortable experience for the patient. Ultimately, through the coordinated regulation of body position and temperature, it assists medical staff in carrying out examination work efficiently.

[0060] In summary, compared with the prior art, the mattress body 2 of this application has a lower leg adjustment area 01, a thigh adjustment area 02, a lumbar adjustment area 03, a side-lying adjustment area 04, and a neck adjustment area 05 arranged sequentially from right rear to front. According to the needs of the patient's examination, different positions of the patient's body can be adjusted to assist medical staff in efficiently performing ultrasound examinations on patients. The lower leg adjustment area 01 and the thigh adjustment area 02 use electric push rods 4, while the lumbar adjustment area 03, the side-lying adjustment area 04, and the neck adjustment area 05 use airbags for assistance. The electric push rods 4 can accurately adjust the lower legs and thighs, while the airbags can effectively cushion the patient's body, thereby improving the comfort of adjustment, meeting the requirements of adjustment accuracy, and improving the patient's physical comfort.
