Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and more particularly to a medical multifunctional prone position supporting device and supporting method. Background Art

[0002] Prone position is a method for treating severe hypoxemia in patients with acute respiratory distress syndrome (ARDS). Currently, prone ventilation is increasingly used in clinical practice, especially for patients with dyspnea and difficult-to-correct hypoxemia. Studies have shown that the principles of prone ventilation are as follows: 1) Improve ventilation. During prone position treatment, the pressure of the heart and abdominal cavity on the lungs can be reduced, while the diaphragm moves downward, reducing the force on the lungs, improving lung compliance, increasing alveolar ventilation in gravity-dependent areas, and alveoli tend to re-expand, promoting carbon dioxide discharge, and reducing alveolar hyperventilation in non-gravity-dependent areas; 2) Improve ventilation / blood perfusion ratio. Prone position can limit the movement of the ribs on the chest side, reduce chest wall compliance and pleural pressure gradient, reduce the alveolar compression ratio, and make lung ventilation more uniform; 3) Facilitate drainage. Prone position is conducive to secretion drainage, improves secretion clearance, and reduces the risk of infection; 4) Others. Prone position can also reduce regional shear force and lung stress and reduce lung damage.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0043] The present invention provides Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a medical multifunctional prone position support device is installed at one end of a hospital bed to support the patient's head and face so that the patient can maintain a prone position on the bed. Its main structure includes: a mounting bracket 1, a support plate 2, a ring-shaped airbag headrest 3 and an air pump device 4. The mounting bracket 1 is used to be fixedly installed on the bed, and the mounting bracket 1 is installed on the bed with a detachable connection structure; the support plate 2 is arranged on the mounting bracket 1, and a through hole 21 is opened on the support plate 2. When in use, the patient's face is downward toward the support plate 2. Therefore, it is necessary to open a through hole 21 on the support plate 2 to allow the patient to breathe smoothly. The annular airbag headrest 3 includes an outer ring airbag 31 and at least one inner ring airbag 32. The outer ring airbag 31 and the inner ring airbag 32 are both arranged on the support plate 2. The outer ring airbag 31 is arranged around the outer side wall of the inner ring airbag 32. The inner ring airbag 32 is used to adjust the inner aperture size of the annular airbag headrest 3. The outer ring airbag 31 and the inner ring airbag 32 are both used to support the patient's head. The outer ring airbag 31 and the inner ring airbag 32 are both arranged around the through hole 21; the air pump device 4 is arranged on the support plate 2, and the air pump device 4 is used to inflate or deflate the outer ring airbag 31 and the inner ring airbag 32.

[0044] It should be noted that currently, for prone ventilation, a variety of mattresses and other devices have been put into use, but there are few devices for protecting and fixing the head and face. The existing prone support device is separated from the bed and placed on the ground for movement. This structure takes up a lot of space and is easy to trip, seriously affecting the safety of the patient. Moreover, the head sizes of patients of different age groups are different. The existing prone support device cannot match the patient's head well and cannot provide the patient with the best head support posture.

[0045] The present invention adjusts the inner hole diameter size of the annular airbag headrest 3 by at least one inner ring airbag 32. When the patient's head size is small, the inner ring airbag 32 in the inner hole of the outer ring airbag 31 is inflated, and the bulging inner ring airbag 32 supports the buffer gasket 33, so that the inner hole of the annular airbag headrest 3 becomes smaller, so that it can support the patient's head and face, thereby achieving the technical effect of adapting to patients of different age groups.

[0046] Preferably, the annular airbag headrest 3 includes an outer ring airbag 31 and two inner ring airbags 32. The two inner ring airbags 32 are of different sizes, one of which is arranged in the inner hole of the other, so that the outer ring airbag 31 and the two inner ring airbags 32 are nested in sequence. When the outer ring airbag 31 with an overly large inner hole diameter cannot support the patient's face well, the inner ring airbag 32 is inflated by the air pump device 4 to expand it to support the patient's face. In order to avoid the outer ring airbag 31 from being over-inflated and causing a foreign body sensation on the patient's neck, the outer ring airbag 31 can be appropriately deflated. Therefore, the inflation volume inside the outer ring airbag 31 and the inner ring airbag 32 can be adjusted.

[0047] In some embodiments, a ventilation fan may be provided on the through hole 21 of the support plate 2, and the ventilation fan is used to ventilate the through hole 21 so that air can circulate and allow the patient to breathe more smoothly.

[0048] Further, such as Figure 4 As shown, the upper end surface of the annular airbag headrest 3 is sleeved with a buffer washer 33, which extends around the extension direction of the annular airbag headrest 3, and the buffer washer 33 is covered on the upper end surface of the outer ring airbag 31 and the upper end surface of the inner ring airbag 32. It can be understood that the buffer washer 33 is arranged on the upper end surface of the outer ring airbag 31 and the upper end surface of the inner ring airbag 32, and the buffer washer 33 is used to support the patient's face, which can avoid the fault gap between the outer ring airbag 31 and the inner ring airbag 32 causing a lack of support for the patient's face, affecting the patient's use experience.

[0049] Further, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a cavity 331 is provided in the buffer gasket 33, and the cavity 331 is a closed cavity 331. The cavity 331 extends along the extension direction of the buffer gasket 33, and a plurality of massage airbags 333 are formed in the cavity 331 through a partition layer 332. The plurality of massage airbags 333 are arranged in the circumferential direction of the buffer gasket 33, and the massage airbags 333 are used to massage the patient's head and face. The plurality of massage airbags 333 are all connected to the pipeline of the air pump device 4, and the air pump device 4 can inflate or deflate each massage airbag 333 individually. The air pump device 4 inflates or deflates the plurality of massage airbags 333 according to a preset frequency and a preset sequence.

[0050] It should be noted that by inflating or deflating the multiple massage airbags 333 on the buffer gasket 33 at a preset frequency and in a preset order, the contact position between the patient's head and the buffer gasket 33 can be massaged to avoid pressure injuries caused by prolonged pressure on the local skin and affecting blood circulation.

[0051] Further, such as Figure 3 and Figure 4 As shown, the outer ring airbag 31, the inner ring airbag 32 and the buffer gasket 33 are all provided with a first notch 34, and the first notch 34 is used to avoid the patient's artificial airway and mechanical ventilation pipeline. When in use, the patient's oxygen tube enters the inner hole of the annular airbag headrest 3 through the first notch 34, so as to prevent the patient's oxygen tube from being squeezed by the annular airbag headrest 3 and the patient's face.

[0052] Furthermore, the width of the first notch 34 is adjustable, and a closing airbag 35 is provided at least at one of the outer ring airbag 31, the inner ring airbag 32 and the buffer gasket 33. The closing airbag 35 is connected to the pipeline of the air pump device 4, and the closing airbag 35 has an inflated state that closes the first notch 34, and a deflated state that opens the first notch 34.

[0053] Further, such as Figure 3 and Figure 4 As shown, a second notch 22 is provided on the support plate 2 at a position corresponding to the first notch 34 , and the second notch 22 extends to the through hole 21 .

[0054] Further, such as Figure 3 and Figure 4 As shown, the lower end surface of the outer ring airbag 31 and the lower end surface of the inner ring airbag 32 are provided with a support ring 36, and the outer ring airbag 31 and the inner ring airbag 32 are fixed on the support plate 2 through the support ring 36; a camera 5 is provided near the through hole on the support plate, and the camera 5 is used to shoot the patient's face. It can be understood that in some embodiments, a notch is also provided on the support ring 36, so that the patient's oxygen tube can enter the inner hole of the annular airbag headrest 3 through the notch to prevent the patient's oxygen tube from being squeezed by the annular airbag headrest 3 and the patient's face. The support ring 36 has a large structural strength, and the support ring 36 can effectively support the annular airbag headrest 3 to prevent the annular airbag headrest 3 from partially collapsing. In addition, a camera 5 is provided near the through hole on the support plate, and the facial expression of the patient is photographed by the camera 5, which is conducive to real-time observation of the condition, and rescue measures can be implemented in time when an emergency occurs.

[0055] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting bracket 1 comprises:

[0056] At least two cross bars 11, the two cross bars 11 are respectively arranged at the two ends of the support plate 2, and the ends of the two cross bars 11 away from the support plate 2 are used for detachable connection to the bed rails or bed legs of the hospital bed;

[0057] and at least two diagonal bracing rods 12, the two diagonal bracing rods 12 are respectively arranged at two ends of the support plate 2, and one end of the two diagonal bracing rods 12 away from the support plate 2 is used for detachably connecting to the crossbeam of the hospital bed or fixing to the ground;

[0058] The length of the diagonal support rod 12 is adjustable, and the pitch angle and height of the support plate 2 are adjustable.

[0059] It is understandable that adjusting the length of the diagonal support rod 12 can achieve the effect of adjusting the pitch angle of the support plate 2; when the length of the diagonal support rod 12 and the inclination angle of the cross bar are adjusted at the same time, the effect of adjusting the height of the support plate 2 can be achieved.

[0060] In some embodiments, the ends of the two diagonal support rods 12 and the two cross rods 11 are provided with detachable fixing claws, and can be detachably connected to the hospital bed through the detachable fixing claws.

[0061] It is understandable that the medical staff can adjust the pitch angle and height of the support plate 2 according to the patient's prone position so that the patient can get the most reasonable prone support.

[0062] Furthermore, the air pump device 4 is arranged on a side of the support plate 2 facing away from the annular airbag headrest 3 , and a cushion layer 23 is arranged on the support plate 2 .

[0063] A second aspect of the present application provides a supporting method for a medical multifunctional prone position supporting device based on any one of the first aspects, the supporting method comprising the following steps:

[0064] Step 1: Move the patient to a preset prone position, make the patient's face face the buffer gasket 33 on the annular airbag headrest 3, and keep the patient in the prone position, wherein the annular airbag headrest 3 includes an outer ring airbag 31 and an inner ring airbag 32;

[0065] Step 2: Deflate the closed airbag 35 on the annular airbag headrest 3 through the air pump device 4, so that the first notch 34 on the annular airbag headrest 3 is opened;

[0066] Step 3, moving the patient's artificial airway and mechanical ventilation pipeline into the inner hole of the annular airbag headrest 3 through the first notch 34;

[0067] Step 4: According to the size of the patient's head and face, the inflation amount of the outer ring airbag 31 and the inner ring airbag 32 is adjusted to adjust the inner aperture size of the annular airbag headrest 3 so that the annular airbag headrest 3 matches the patient's face;

[0068] Step five, start the air pump device 4, so that the air pump device 4 inflates or deflates the plurality of massage airbags 333 on the buffer gasket 33 at a preset frequency and in a preset order to massage the patient's head.

[0069] In summary, the present application provides a medical multifunctional prone support device and support method. The scheme of the present invention adjusts the inner aperture size of the annular airbag headrest 3 by at least one inner ring airbag 32. When the patient's head size is small, the inner ring airbag 32 in the inner hole of the outer ring airbag 31 is inflated, and the bulging inner ring airbag 32 supports the buffer gasket 33, so that the inner hole of the annular airbag headrest 3 becomes smaller, so that it can support the patient's head and face, thereby achieving the technical effect of adapting to patients of different age groups. In addition, the massage airbags 333 on the buffer gasket 33 are inflated or deflated at a preset frequency and a preset sequence, and the position where the patient's head contacts the buffer gasket 33 can be massaged, so that the blood at the position where the patient's head contacts the buffer gasket 33 can be unblocked, so that the patient can relax and avoid pressure injuries.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
