Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an auxiliary device for changing the position of critically ill clinical patients. Background Technology

[0002] ARDS patients, or Acute Respiratory Distress Syndrome (ARDS), are patients with acute and progressive respiratory failure caused by a variety of serious etiologies. The core pathological mechanism is alveolar damage and impaired gas exchange due to lung inflammation. The clinical manifestations are characterized by severe hypoxemia. The disease progresses rapidly and often requires emergency medical intervention, and is frequently seen in critical care settings.

[0003] ARDS patients often need to maintain a prone position for extended periods to meet treatment requirements. However, after prolonged prone positioning, it's necessary to turn them over to reduce pressure and effectively prevent pressure sores. Currently, patient turning is usually done manually by healthcare professionals, which is time-consuming and laborious. Furthermore, the patient's body lacks support after turning, making them prone to changing position. Additionally, prolonged lying down can lead to sweating on the back, resulting in heat rash or other rashes. Therefore, this method still has some limitations.

[0004] Therefore, a postural adjustment device for critically ill patients is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention designs an auxiliary device for changing the position of critically ill clinical patients. This device can be adaptively clamped onto the bed, and through the interchangeable clamping positions, it can assist medical staff in turning the patient over. After turning, the device can also provide support for the patient. Furthermore, the device can be installed on both sides of the bed to ensure the patient's position. Additionally, while supporting the patient, the device can also blow a gentle breeze towards the patient's back, allowing sweat to evaporate quickly and reducing the occurrence of heat rash and rashes.

[0006] To achieve the above-mentioned technical effects, the present invention discloses an auxiliary device for changing the position of critically ill clinical patients, including a base, a support plate, and a support device; the support plate is movably mounted on one side of the upper end of the base via a rotating shaft, and the support device is fixedly mounted on the inner side of the base, while the upper end of the support device is movably connected to the support plate. The support device includes a second motor, a receiving plate, a first bevel gear, a C-shaped plate, a second bevel gear, and a screw. The receiving plate is fixedly installed on the inner side wall of the base. The direction plate is movably installed on one side of the upper end of the receiving plate. The second bevel gear is movably installed below the C-shaped plate. The first bevel gear is movably installed axially on the receiving plate, and the first and second bevel gears mesh with each other. The screw is movably installed in the middle of the second bevel gear via a thread, and the other end of the screw is movably installed on the lower end of the support plate. Meanwhile, the second motor is installed on the side wall of the base, and the output shaft is fixedly installed on the first bevel gear. The forward or reverse rotation of the motor controls the lifting and lowering of the screw, thereby driving the support plate to rotate around the axis. Furthermore, the support plate is provided with several air outlets; and the air outlets are interconnected. At the same time, an air pump is fixedly installed at the bottom of the base, and an air guide pipe is fixedly installed on the air pump. The end of the air guide pipe is connected to the air outlet. Furthermore, support pads are fixedly installed on both sides of the upper end of the base plate; Furthermore, a clamping assembly is movably mounted on the lower end of the base. The clamping assembly includes a clamping plate, a fixing bolt, a slider, a first motor, and a lead screw.

Detailed Implementation

[0011] To address the technical problems of ARDS patients needing to be manually turned over after prolonged prone positions, which is time-consuming and laborious for medical staff, and the lack of back support after turning over makes it easy to change body position, this invention solves the problems of time-consuming and laborious manual turning and unstable body position by coordinating the clamping component 12 at the lower end of the base 1 with the internal support device 15.

[0012] Example 1

[0013] A postural adjustment device for critically ill patients includes a base 1, a support plate 2, and a support device 15. The support plate 2 is movably mounted on one side of the upper end of the base 1 via a pivot, and the support device 15 is fixedly mounted on the inner side of the base 1. The upper end of the support device 15 is movably connected to the support plate 2. The support device 15 includes a second motor 151, a receiving plate 152, a first bevel gear 153, a U-shaped plate 154, a second bevel gear 155, and a screw 156. The receiving plate 152 is fixedly installed on the inner side wall of the base 1. The direction plate is movably installed on one side of the upper end of the receiving plate 152. The second bevel gear 155 is movably installed below the U-shaped plate 154. The first bevel gear 153 is movably installed axially on the receiving plate 152, and the first bevel gear 153 and the second bevel gear 155 mesh with each other. The screw 156 is movably installed in the middle of the second bevel gear 155 through a thread, and the other end of the screw 156 is movably installed on the lower end of the receiving plate 152. At the same time, the second motor 151 is installed on the side wall of the base 1, and the output shaft is fixedly installed on the first bevel gear 153. The forward or reverse rotation of the motor controls the lifting and lowering of the screw 156, thereby driving the receiving plate 152 to rotate around the axis. Specifically, in the aforementioned support device 15, the output shaft of the second motor 151 drives the first bevel gear 153 to rotate. Because the first bevel gear 153 meshes with the second bevel gear 155 below the U-shaped plate 154, the second bevel gear 155 rotates along with it. Since the middle part of the second bevel gear 155 is threadedly connected to the screw 156, the threaded transmission causes the screw 156 to rise and fall axially. The top of the screw 156 is movably connected to the lower end of the support plate 2, ultimately driving the support plate 2 to rotate around the shaft at the upper end of the base 1. When it is necessary to change a prone patient to a lateral position, this device can be installed on the same side of the bed. First, activate one support device 15 on the same side to rotate the support plate 2 upwards to a suitable angle, lifting one side of the patient's body to complete the initial turning. Then, the support plate 2 of the other device supports and fixes the patient's body, realizing the "alternating support on the same side" position conversion process. The entire operation only requires medical staff to control the motor through the control panel 13, eliminating the need to manually lift the patient, significantly reducing the labor intensity of medical staff and solving the problem of time-consuming and laborious manual turning. At the same time, the support plate 2 continues to provide support for the patient's back after turning, and together with the support pads 22 on both sides of the upper end of the base 1 to limit the movement of the body on both sides, it effectively prevents the patient from shifting position due to lack of support, ensuring the stability of ARDS patients after positional changes, and meeting the need to accurately maintain position during treatment.

[0014] In this embodiment, the base 1 is triangular, and a control panel 13 is fixedly installed on the outside of the base 1. The triangular structure of the base 1 provides good load-bearing capacity and anti-tipping performance. When the support device 15 drives the support plate 2 to lift the patient's body, the triangular base 1 can evenly distribute the patient's weight onto the bed, avoiding excessive local force that could cause the device to deform. This further ensures the patient's safety during position changes and solves the problem of the device easily tipping over due to uneven force when supported on one side.

[0015] In this embodiment, the support plate 2 has several air outlets 21 that are interconnected. An air pump 3 is fixedly installed at the bottom of the base 1, and an air guide pipe 31 is fixedly installed on the air pump 3. The end of the air guide pipe 31 is connected to the air outlets 21. The air pump 3 at the bottom of the base 1 is connected to the air outlets 21 via the air guide pipe 31. When the device is in the supported state, the air pump 3 is activated, and the airflow generated by the air pump 3 is delivered to the air outlets 21 via the air guide pipe 31, and then evenly blown onto the patient's back. The airflow speed can be adjusted via the control panel 13 to ensure that the gentle breeze does not cause the patient to feel cold due to excessive wind speed, while effectively accelerating the evaporation of sweat on the back, promptly removing heat from the back, and preventing sweat from remaining on the skin surface for a long time. The air vents 21 are arranged in a linear array and interconnected, allowing airflow to be evenly distributed within the support plate 2152. The airflow from each air vent 21 remains consistent, preventing insufficient local ventilation that could lead to sweat buildup. Simultaneously, support pads 22 are fixedly installed on both sides of the upper end of the base plate. These support pads 22 support the patient's back, creating a suspended effect that allows the airflow generated by the air pump 3 to gently cool the patient's back.

[0016] Specifically, in this embodiment, based on the base 1 described above, a clamping assembly 12 is movably installed at the lower end of the base 1. The clamping assembly 12 includes a clamping plate 121, a fixing bolt 122, a slider 123, a first motor 124, and a lead screw 125. The lead screw 125 is fixedly installed on the output shaft of the first motor 124, and the slider 123 is slidably installed on the lead screw 125. The clamping plate 121 is fixedly installed at the lower end of the slider 123, and the fixing bolt 122 is movably installed at the lower end of the clamping plate 121. The clamping assembly 12 can clamp the device onto the hospital bed. Specifically, when in use, the first motor 124 is started, and its output shaft drives the lead screw 125 to rotate. The lead screw 125 drives the slider 123 to move axially, thereby adjusting the distance between the clamping plate 121 and the edge of the bed. After the clamping plate 121 is in contact with the bed, the fixing bolt 122 is tightened to achieve a firm connection between the device and the bed.

[0017] Specifically, the operating principle of this device is as follows: First, a stable connection with the bed is achieved through the clamping assembly at the lower end of the base. Then, the first motor 124 is started to drive the lead screw to rotate, which drives the slider 123 and the clamping plate 121 to move. After the clamping plate 121 is in contact with the edge of the bed board 4, the fixing bolt 122 is tightened to lock it in place, ensuring that there is no risk of displacement or tipping of the device during the body position change process, and providing a stable foundation for subsequent operations. When it is necessary to turn a prone patient to a lateral position, this device can be installed on the same side or both sides of the bed. Medical staff can start the second motor 151 of the support device through the control panel 13. The output shaft of the second motor 151 drives the first bevel gear 153 to rotate, and the second bevel gear 155, which meshes with the first bevel gear 153, rotates accordingly. Through the threaded transmission, the screw is driven to rise and fall axially, thereby driving the support plate 152 to rotate upward around the rotating axis at the upper end of the base 1. If two devices on the same side are used in combination, the support plate 152 of one device first lifts one side of the patient's body to complete the initial turning, and then the support plate 152 of the other device supports and fixes the patient's body, realizing the position change of "alternating support". There is no need for medical staff to manually lift, which greatly reduces the labor intensity. After the turning is completed, the support plate 152 continues to provide support for the patient's back. Together with the support pads 22 on both sides of the upper end of the base 1, the patient's body is limited on both sides, which effectively avoids the position shift and ensures the positional stability required for treatment. Simultaneously, the internal air pump 3 can be activated. The airflow generated by the air pump 3 is delivered through the air duct 31 to the interconnected air outlets on the support plate 152, forming a uniform breeze that blows onto the patient's back. The support pad can also moderately suspend the patient's back, facilitating airflow, accelerating sweat evaporation, removing heat, and reducing the occurrence of heat rash and rashes. The airflow speed can be adjusted via the control panel 13 to ensure a gentle breeze without the risk of catching a cold, balancing comfort and practicality. The entire usage process integrates body position changing, stable support, and heat dissipation functions through the coordination of the mechanical structure and the electronic control system. Furthermore, the fixed straps 23 and fixed holes 24 can secure the patient, preventing falls during turning. Specifically, as shown... Figure 6 As shown, in Figure 6 In this device, at least one pair of these devices can be placed on each side of the bed frame for turning the patient over. Specifically, they are placed on the inside of the bed frame, clamped to the bed body, without affecting the original structure of the bed body, and can be used directly. They can also be placed together with the bed board, enabling various turning movements for the patient, which is convenient and practical.
