Description

Technical Field

[0001] This utility model relates to the technical field of assisted recovery, and in particular to a multi-angle adjustable prone ventilation support frame. Background Technology

[0002] In the fields of critical care medicine and postoperative care, prone positioning ventilation is an important treatment for improving oxygenation in patients with acute respiratory distress syndrome (ARDS). Traditional prone positioning support devices mostly use a fixed flat structure, requiring multiple people to assist the patient in achieving the prone position, which increases the workload of medical staff and the risk of patient falls. At the same time, existing support devices cannot flexibly adjust the height according to the patient's height and body type, making it more difficult for obese patients or those with limited joint mobility to achieve the prone position. Utility Model Content

Detailed Implementation

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] This utility model relates to a multi-angle adjustable prone ventilation support frame, such as... Figures 1 to 4 As shown, it includes:

[0037] Support mechanism 1 is independently and fixedly installed, and support mechanism 1 has a lifting function, which can adjust the height according to the specific needs of the patient;

[0038] The fixing plate 2 is installed on the support mechanism 1, and the fixing plate 2 is provided with a connector 3. A support shaft 4 is rotatably installed in the inner hole of the connector 3. The fixing plate 2 is used to support the upper body of the patient.

[0039] Fixing member 5 is installed on support shaft 4 and rotates synchronously with support shaft 4. A flip plate 6 is installed on fixing member 5, which is used to support the lower body of the patient.

[0040] The adjustment mechanism 7 is installed on the support mechanism 1 and connected to the support shaft 4. The adjustment mechanism 7 is used to adjust the installation angle of the flip plate 6. The angle of the flip plate 6 can be easily adjusted through the adjustment mechanism 7.

[0041] The locking mechanism 8 is installed on the fixed plate 2. The locking mechanism 8 is used to rotate and lock when the fixed plate 2 and the flip plate 6 are on the same plane, so as to ensure stability during the treatment process.

[0042] The working principle of this device is as follows:

[0043] First, based on the patient's body size and treatment needs, the height of the entire support frame is adjusted to a suitable position using the support mechanism 1. The patient lies face down on the fixation plate 2, providing full support for the patient's chest and abdomen. At this point, the fixation plate 2 provides a stable support base for the patient. Next, the angle of the flip plate 6 is adjusted so that it can support the patient's legs. This step is accomplished by operating the adjustment mechanism 7, which allows the flip plate 6 to rotate around the support axis 4 until it flips to a horizontal position with the fixation plate 2. The locking mechanism 8 is then used to lock the positions of the fixation plate 2 and the flip plate 6, ensuring the stability and safety of the support structure throughout the treatment process.

[0044] The support mechanism 1 is independently fixed and has a lifting function, which can flexibly adjust the height according to the patient's body shape and treatment scenario. The fixing plate 2 is installed on the support mechanism 1 to provide a stable support foundation for the patient's upper body. The support shaft 4, which is rotatably installed in the connector 3, together with the fixing part 5 and the flip plate 6, provides a flexible adjustment structure for the support of the patient's lower body. The adjustment mechanism 7 is connected to the support shaft 4. Medical staff can easily adjust the angle of the flip plate 6 by operating the adjustment mechanism 7 to reduce the difficulty of the patient's prone position. When the fixing plate 2 and the flip plate 6 are on the same plane, the locking mechanism 8 plays a role in rotating and locking the two, effectively preventing the patient from shifting due to the shaking of the support structure during treatment, and greatly improving the stability and safety of the treatment process.

[0045] As a preferred option, such as Figures 1 to 4 As shown, the support mechanism 1 includes:

[0046] The base 11 is configured as a Y-shaped structure, with the opening side of the Y-shaped structure located at the end of the flip plate 6, and a fuma wheel 12 is provided at the bottom of the base 11;

[0047] The guide post 13 is mounted on the base 11, and an extension 14 is slidably mounted in the inner cavity of the guide post 13 along the length direction. The fixing plate 2 is mounted on the extension 14.

[0048] The threaded post 15 is rotatably installed in the inner hole of the base 11, and the threaded post 15 is connected to the threaded inner hole of the extension 14.

[0049] Drive mechanism 16, mounted on base 11, is used to provide rotational force to threaded post 15;

[0050] The Y-shaped base 11, with its opening facing the flip plate 6, provides ample space for patients and medical staff to move around and facilitates operation. The casters 12 at the bottom of the base 11 make the support frame easy to move within the ward and lock in position after being moved to the designated location. The guide column 13, mounted on the base 11, provides precise guidance for the sliding of the extension 14, ensuring that the fixed plate 2 remains stable during lifting and lowering, avoiding swaying or deviation. The threaded column 15 engages with the threaded inner hole of the extension 14, enabling precise adjustment of the height of the fixed plate 2. The drive mechanism 16, mounted on the base 11, provides rotational power to the threaded column 15. Medical staff can easily adjust the height of the fixed plate 2 simply by operating the drive mechanism 16, significantly reducing the difficulty of operation and saving manpower.

[0051] As a preferred option, such as Figures 1 to 4 As shown, the drive mechanism 16 includes:

[0052] The drive shaft 16a is rotatably mounted in the through hole of the base 11, and the drive sprocket 16b is coaxially mounted on the drive shaft 16a.

[0053] Driven sprocket 16c is coaxially mounted on threaded post 15, and chain 16d is meshed on driven sprocket 16c and driving sprocket 16b;

[0054] The adjusting wheel 16e is coaxially mounted on the drive shaft 16a, and a rocker arm 16f is provided on the adjusting wheel 16e;

[0055] An isolator 16g is mounted on the base 11, and the chain 16d is located inside the isolator 16g;

[0056] The drive shaft 16a is rotatably mounted in the through hole of the base 11, providing stable rotational support for the drive sprocket 16b. The chain drive system, consisting of the drive sprocket 16b, driven sprocket 16c, and chain 16d, efficiently transmits the rotation of the drive shaft 16a to the threaded column 15, achieving precise power transmission. This not only ensures the stability of the threaded column 15's rotation but also allows for flexible adjustment of the height adjustment speed and precision through the sprocket's gear ratio. The adjusting wheel 16e is coaxially mounted on the drive shaft 16a and, together with the rocker arm 16f, provides a convenient point of force application for medical personnel. By rocking the rocker arm 16f, medical personnel can easily drive the drive shaft 16a to rotate, thereby adjusting the height of the fixed plate 2. The operation is simple and effortless. The isolation piece 16g installed on the base 11 encloses the chain 16d, effectively preventing accidental contact with the chain 16d and avoiding safety accidents caused by chain operation, ensuring the safety of medical personnel and patients. It also prevents foreign objects from entering the chain drive system, reducing chain wear and extending the service life of the drive mechanism 16.

[0057] As a preferred option, such as Figures 1 to 4 As shown, the adjustment mechanism 7 includes:

[0058] The drive shaft 71 is rotatably mounted in the reserved hole of the extension 14, and a worm gear 72 is coaxially mounted on the drive shaft 71;

[0059] The worm gear 73 is coaxially mounted on the support shaft 4, and the worm 72 is meshed with the worm gear 73.

[0060] The drive wheel 74 is coaxially mounted on the power shaft 71. An extension rod 75 is provided on the drive wheel 74, and the extension rod 75 is eccentrically positioned with respect to the drive wheel 74.

[0061] The drive shaft 71 is rotatably mounted in the pre-drilled hole of the extension 14, providing a stable mounting base for the worm gear 72. The meshing of the worm gear 72 and the worm wheel 73 utilizes the large transmission ratio and self-locking characteristics of the worm gear transmission to not only smoothly and accurately transmit the rotation of the drive shaft 71 to the support shaft 4, enabling precise fine-tuning of the angle of the flip plate 6, but also prevents the flip plate 6 from rotating arbitrarily after adjustment due to its self-locking characteristics. The drive wheel 74 is coaxially mounted on the drive shaft 71, and its extension rod 75 is eccentrically set with the drive wheel 74 to provide driving force for the rotation of the drive shaft 71. This design allows medical staff to simply operate the drive wheel 74 to drive the drive shaft 71 and adjust the angle of the flip plate 6, greatly simplifying the adjustment process.

[0062] As a preferred option, such as Figures 1 to 4 As shown, the locking mechanism 8 includes:

[0063] The positioning pin 81 is slidably installed in the guide groove of the fixed plate 2, and the positioning pin 81 is connected to the limiting groove of the flip plate 6.

[0064] Bolt 82 is installed in the threaded through hole of locating pin 81, and bolt 82 is connected to the assembly hole of fixing plate 2.

[0065] The positioning pin 81 is slidably installed in the guide groove of the fixed plate 2, which facilitates precise alignment with the limiting groove of the flip plate 6. When the flip plate 6 and the fixed plate 2 are on the same plane, the positioning pin 81 is slid into the limiting groove, which can quickly restrict the rotation of the flip plate 6 relative to the fixed plate 2 and achieve initial positioning. The bolt 82 is installed in the threaded through hole of the positioning pin 81 and is connected to the assembly hole of the fixed plate 2. By tightening the bolt 82, the positioning pin 81 can be further firmly fixed on the fixed plate 2 to prevent the positioning pin 81 from accidentally falling out, thereby stably locking the position of the flip plate 6 and the fixed plate 2. This double locking mechanism is not only easy to operate, but also allows medical staff to quickly complete the locking operation without the need for complicated tools, saving treatment preparation time.

[0066] As a preferred option, such as Figures 1 to 4 As shown, auxiliary handles 9 are installed at both ends of the fixing plate 2. The auxiliary handles 9 are used by the patient to grasp and prevent slipping.

[0067] When the patient lies prone on the fixation board 2 for prone ventilation therapy, they can directly grasp the auxiliary handle 9 to provide additional leverage. This design not only allows the patient to maintain a relatively fixed posture during treatment, ensuring the treatment effect, but also provides the patient with a sense of psychological security, making them more relaxed during the treatment process. In addition, the auxiliary handle 9 helps the patient to use leverage when adjusting their position, reducing discomfort caused by changes in position and alleviating the burden on the patient during treatment. It comprehensively meets the patient's support and safety needs during the treatment process, ensuring the smooth progress of prone ventilation therapy.

[0068] As a preferred option, such as Figures 1 to 4 As shown, the surfaces of the fixed plate 2 and the flip plate 6 are covered with pressure-dispersing silicone pads. A flexible pressure sensor array can be configured inside the silicone pads to trigger an alarm when the local pressure intensity is >32mmHg. The fixed plate 2 and the flip plate 6 are each composed of multiple independent adjustable modules, and each module supports 0°-45° angle adjustment.

[0069] Pressure-dispersing silicone pads cover the surfaces of the fixation plate 2 and the flip plate 6. Their excellent flexibility and elasticity effectively disperse the pressure of the patient's body on the support surfaces, reducing the risk of localized pressure concentration and the likelihood of pressure ulcers. The flexible pressure sensor array within the silicone pads can monitor the pressure intensity at the contact points between the patient's body and the fixation plate 2 and flip plate 6 in real time and accurately. Once the localized pressure intensity exceeds 32 mmHg, a critical value that may trigger pressure ulcers, an alarm will be immediately triggered, alerting medical staff to adjust the patient's position promptly to prevent pressure ulcers. Furthermore, the fixation plate 2 and flip plate 6 consist of multiple independent adjustable modules, each with an angle that can be flexibly adjusted within the range of 0°-45°. This design provides the support frame with high flexibility, allowing medical staff to personalize the angle of each module according to the patient's body shape and treatment needs, providing a more body-conforming support, further dispersing pressure, optimizing the treatment experience, and comprehensively ensuring the patient's comfort and safety during prone ventilation therapy, significantly improving treatment effectiveness and the quality of medical care.

[0070] The multi-angle adjustable prone ventilation support frame of this utility model can be installed, connected or set up using common mechanical methods. Any method that can achieve its beneficial effect can be implemented.

[0071] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
