Description

Technical Field

[0001] This invention specifically relates to a prone ventilation aid for ARDS patients. Background Technology

[0002] ARDS is short for Acute Respiratory Distress Syndrome, a type of respiratory failure caused by a variety of diseases that lead to fluid accumulation in the lungs and low blood oxygen levels. Patients experience shortness of breath, usually rapid and shallow breathing, mottled or bluish skin, and abnormalities in the function of other organs such as the heart and brain.

[0003] During the treatment of ARDS patients, prone ventilation is often used to assist their breathing. The purpose of prone ventilation is to optimize the ventilation-perfusion ratio of ARDS patients, improve lung function, and redistribute pulmonary blood flow so that oxygen can be increased from low-ventilation areas to high-ventilation areas, thereby improving the patient's oxygen supply and reducing mortality.

[0004] Currently, when treating ARDS patients with prone ventilation, related devices are needed for assistance. For example, Chinese invention patent No. 202110453369.8 provides a protective device for supporting prone mechanical ventilation. During use, this device can support the patient's head through a head support mechanism to reduce the danger caused by the patient's head movement, and can fix the patient's upper limbs through a fixation mechanism to prevent the patient's body movement and protect the patient.

[0005] However, existing prone ventilation aids still have certain drawbacks in use, such as the inability to adjust the support position according to the patient's supine or prone position, which makes it inconvenient for the patient to undergo prone ventilation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention proposes a prone ventilation assist device for ARDS patients, which solves the technical problem mentioned in the background art: existing prone ventilation assist devices cannot adjust the support position according to the patient's supine or prone position, resulting in certain inconveniences for the patient during prone ventilation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a prone ventilation assist device for ARDS patients, comprising:

[0008] Bed frame;

[0009] A turning board is hinged to the bed frame, and a driving mechanism is provided at the bottom of the bed frame to drive the turning board to flip along its hinge point with the bed frame;

[0010] A support frame, which can be raised and lowered, is mounted on the bed frame, and the support frame is provided with a flexible support ring; and

[0011] The first linkage component is connected to the support frame and the drive mechanism. During the process of the drive mechanism driving the turning board to flip, the first linkage component drives the support frame to rise and fall, causing the support ring to protrude from the surface of the bed.

[0012] In a preferred embodiment, the drive mechanism includes:

[0013] A telescopic motor is fixedly installed on the bottom surface of the bed frame;

[0014] A connecting frame is disposed at the telescopic end of the telescopic motor, and a first drive column is disposed at one end of the connecting frame; and

[0015] The first sliding frame is located at the hinge point between the turning plate and the bed body, and forms an angle with the bed body. The first drive column is slidably engaged in the first sliding frame.

[0016] In a preferred embodiment, the turning plate has a groove, the support frame is disposed in the groove, and the bottom surface of the support frame is provided with a positioning frame. The bottom of the bed is provided with a vertically arranged positioning column, and the positioning frame is slidably sleeved on the positioning column.

[0017] In a preferred embodiment, the first linkage component includes:

[0018] Wedge-shaped blocks are disposed on the connecting frame; and

[0019] A roller is disposed on the bottom surface of the support frame, and the inclined surface of the wedge block abuts against the roller.

[0020] In a preferred embodiment, a positioning frame is provided at the bottom of the bed, and the connecting frame slides through the positioning frame along its axis.

[0021] In a preferred embodiment, the bottom of the bed is provided with a mounting groove, which passes through the hinge axis between the turning plate and the bed, and the first sliding frame is disposed in the mounting groove.

[0022] In a preferred embodiment, the bed is provided with a pillow, the pillow has a ventilation cavity, and the pillow also has a groove that connects the ventilation cavity to the outside. The ventilation cavity is provided with a height-adjustable support pad.

[0023] In a preferred embodiment, the support frame and the support pad are connected by a second linkage component, and the support frame drives the support pad to move in the opposite direction during the lifting and lowering process via the second linkage component.

[0024] In a preferred embodiment, the second linkage component includes:

[0025] A support frame is provided at the bottom of the bed frame;

[0026] The connecting rod has its middle section hinged to the support frame, and its two ends are respectively provided with a second sliding frame and a third sliding frame;

[0027] The second drive column is disposed at the bottom of the support pad and is slidably engaged within the second sliding frame; and

[0028] The third drive column is located at the bottom of the support pad and is slidably engaged within the third sliding frame.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. When using this device, the patient can lie on the bed to rest. In the initial state, the bed, the turning board, and the upper surface of the support ring are on the same plane, thus not disturbing the patient's rest and providing a comfortable resting environment. When the patient needs prone ventilation, the turning board can be driven by the drive mechanism to rotate along its hinge point with the bed to lift one side of the patient's body, assisting the patient in turning over. During the rotation of the turning board, the drive mechanism drives the support frame to rise through the first linkage component, causing the support ring to rise and protrude from the bed surface. The support ring can support the patient's shoulders, hips, etc., and reduce the pressure on the patient's chest and abdomen, so that the support position can be adjusted according to the patient's posture. This makes prone ventilation more convenient and effortless, improving the functionality of the device.

[0031] 2. During the process of supporting the patient in prone ventilation, the patient can place their face in contact with the pillow. As the support frame rises, it drives the second drive column to rise as well. During the rise, the second drive column, in cooperation with the second sliding frame, drives the connecting rod to rotate along its hinge point with the support frame. Through the cooperation of the third sliding frame and the third drive column, it drives the support pad to descend, exposing the ventilation chamber. The patient can then place their mouth and nose in the ventilation chamber for prone ventilation. The ventilator tubing can also be inserted into the ventilation chamber through the tubing slot to supply oxygen to the patient, making prone ventilation more convenient and further improving the functionality of the device.

[0045] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0046] Example:

[0047] like Figure 1 , 3As shown in Figures 4 and 5, the present invention provides a prone ventilation assist device for ARDS patients, including a bed body 101, a hinged turning board 201 on the bed body 101, and a driving mechanism at the bottom of the bed body 101 for driving the turning board 201 to rotate along the hinge point between it and the bed body 101. The driving mechanism includes a telescopic motor 301 fixedly mounted on the bottom surface of the bed body 101, a connecting frame 302 at the telescopic end of the telescopic motor 301, a first driving column 303 at one end of the connecting frame 302, a first sliding frame 203 at the hinge point between the turning board 201 and the bed body 101, the first sliding frame 203 forming an angle with the bed body 101, the first driving column 303 being slidably engaged in the first sliding frame 203, an installation groove 103 at the bottom of the bed body 101, the installation groove 103 passing through the hinge axis between the turning board 201 and the bed body 101, and the first sliding frame 203 being disposed in the installation groove 103.

[0048] In its initial state, the patient can lie on the bed 101 to rest and receive treatment. When prone ventilation is required, the telescopic motor 301 can be activated. The telescopic end of the telescopic motor 301 extends, driving the connecting frame 302 to move. A positioning frame 104 is provided at the bottom of the bed 101, and the connecting frame 302 slides along its axis within the positioning frame 104. The positioning frame 104 provides positioning support for the movement of the connecting frame 302, improving the stability of the device structure. During the movement, the connecting frame 302 drives the first drive column 303 to slide within the first sliding frame 203. Thus, the first drive column 303 and the first sliding frame 203 work together to drive the first sliding frame 203 to move. The mounting groove 103 provides space for the movement of the first sliding frame 203, driving the turning plate 201 to rotate along its hinge point with the bed 101, lifting the patient's side and assisting the patient in turning over, allowing the patient to quickly move to a prone position.

[0049] like Figure 1 , 3 As shown in Figures 5 and 6, in this embodiment, a support frame 401 is provided on the bed 101 in a height-adjustable manner. A flexible support ring 404 is provided on the support frame 401. A groove 202 is provided on the turning plate 201. The support frame 401 is located in the groove 202. A positioning frame 402 is provided on the bottom surface of the support frame 401. A vertically arranged positioning column 102 is provided at the bottom of the bed 101. The positioning frame 402 is slidably sleeved on the positioning column 102.

[0050] In its initial state, the support ring 404 is located within the groove 202, ensuring that the upper surfaces of the bed frame 101, the turning board 201, and the support ring 404 are on the same plane, thus preventing discomfort for the patient when lying supine on the bed. Furthermore, the support frame 401 can be raised and lowered with the cooperation of the positioning frame 402 and the positioning column 102.

[0051] like Figure 2 , 5 As shown in Figure 6, in this embodiment, the support frame 401 and the drive mechanism are connected by a first linkage component. During the process of the drive mechanism driving the turning plate 201 to flip, the support frame 401 is raised and lowered through the first linkage component, causing the support ring 404 to protrude from the surface of the bed 101. The first linkage component includes a wedge block 304 disposed on the connecting frame 302, and a roller 403 is disposed on the bottom surface of the support frame 401. The inclined surface of the wedge block 304 abuts against the roller 403.

[0052] When the telescopic motor 301 starts, it drives the turning board 201 to rotate and simultaneously drives the wedge block 304 to slide. During the sliding process, the wedge block 304 can push the roller 403 to rise through the inclined surface, so that the support frame 401 rises and falls. After the support frame 401 rises, it drives the support ring 404 to protrude from the surface of the bed 101. The flexible material support ring 404 supports the patient's shoulders and hips to reduce the pressure on the chest and abdomen, thereby making prone ventilation more effortless and improving the treatment effect for the patient.

[0053] like Figure 1 , 3 As shown in Figure 4, in this embodiment, a pillow 106 is provided on the bed 101, and a ventilation chamber 107 is formed inside the pillow 106. A channel 108 connecting the ventilation chamber 107 to the outside is also formed on the pillow 106. A height-adjustable support pad 501 is provided inside the ventilation chamber 107. When the patient is in a supine position, their head can be placed on the pillow 106. Initially, the support pad 501 covers the ventilation chamber 107, and the support pad 501 and the pillow 106 are on the same plane, thus facilitating stable support for the patient's head. When prone ventilation is required, the support pad 501 can be lowered to expose the ventilation chamber 107, allowing the patient's mouth and nose to be placed inside the ventilation chamber 107 for breathing. The annular pillow 106 supports the patient's face without affecting their breathing, and the ventilator's air supply tubing extends into the channel 108 to supply oxygen to the patient.

[0054] like Figure 2 , 3As shown in Figures 4 and 6, in this embodiment, the support frame 401 and the support pad 501 are connected by a second linkage assembly. During the lifting and lowering process, the support frame 401 drives the support pad 501 to lift and lower in the opposite direction through the second linkage assembly. The second linkage assembly includes a support frame 105 disposed at the bottom of the bed 101, a connecting rod 503 hinged to the support frame 105 at its middle section, a second sliding frame 504 and a third sliding frame 505 respectively disposed at both ends of the connecting rod 503, a second drive column 405 disposed at the bottom of the support pad 501, the second drive column 405 being slidably engaged in the second sliding frame 504, and a third drive column 502 disposed at the bottom of the support pad 501, the third drive column 502 being slidably engaged in the third sliding frame 505.

[0055] During the process of starting the telescopic motor 301 to rotate the turning board 201 and raise the support frame 401, the second drive column 405 at the bottom of the support frame 401 rises. Through the cooperation of the second drive column 405 and the second sliding frame 504, the connecting rod 503 rotates along its hinge point with the support frame 105. During the rotation of the connecting rod 503, the support pad 501 is lowered through the cooperation of the third drive column 502 and the third sliding frame 505, so that the ventilation chamber 107 and the tube groove 108 are exposed to facilitate the patient's prone ventilation. The patient's face can be supported without the need to install other head and face support devices, and the patient's breathing is not affected.

[0056] Specific usage and beneficial effects of the present invention:

[0057] When in use, the patient can lie on the bed 101 to rest. In the initial state, the bed 101, the turning board 201 and the upper surface of the support ring 404 are on the same plane, so as not to disturb the patient's rest and to provide the patient with a comfortable resting environment. When a patient needs prone ventilation, the extension end of the telescopic motor 301 can be controlled to move the first drive column 303. In turn, the first drive column 303 and the first sliding frame 203 work together to drive the turning plate 201 to flip along its hinge point with the bed 101, lifting one side of the patient's body to assist the patient in turning over. During the flipping process, the telescopic motor 301 simultaneously controls the wedge block 304 to slide. In turn, the wedge block 304 and the roller 403 work together to drive the support frame 401 to rise, causing the support ring 404 to rise and protrude from the surface of the bed 101. The support ring 404 can support the patient's shoulders, hips, and other positions, and reduce the pressure on the patient's chest and abdomen. This allows for adjustment of the support position according to the patient's posture, making prone ventilation more convenient and effortless, and improving the functionality of the device.

[0058] During the process of supporting a patient in prone ventilation, the patient can place their face in contact with the pillow 106. As the support frame 401 rises, it drives the second drive column 405 to rise. During the rise, the second drive column 405, through its cooperation with the second sliding frame 504, drives the connecting rod 503 to rotate along its hinge point with the support frame 105. Through the cooperation of the third sliding frame 505 and the third drive column 502, it drives the support pad 501 to fall, exposing the ventilation chamber 107. The patient can then place their mouth and nose in the ventilation chamber 107 for prone ventilation. The ventilator tubing can also be inserted into the ventilation chamber 107 through the tubing groove 108 to supply oxygen to the patient, making prone ventilation more convenient and further improving the functionality of the device.

[0059] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
