Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a prone facial support device. Background Technology

[0002] A growing body of research has demonstrated that prone positioning ventilation can effectively improve oxygenation and reduce mortality in patients. Prone positioning ventilation refers to a therapeutic positioning technique used during mechanical ventilation to help patients assume a prone position in order to improve their oxygenation status. It can significantly improve the oxygenation status of patients with acute respiratory distress syndrome.

[0003] Currently, when patients undergo ventilation therapy in the prone position, it generally takes a relatively long time, during which the patient's face is in a side-lying position. Prolonged side-lying positions can put pressure on the patient's eyes, ears, and facial skin, easily causing pressure injuries. Furthermore, because the patient is in a sedated (anesthetized) state, they cannot change their facial orientation themselves, requiring medical staff to rotate the patient's face every two hours, which is physically demanding for the medical personnel. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a prone facial support device. This device solves the problem that prolonged prone or side-lying positions can easily cause pressure injuries to the affected areas when patients are undergoing supine ventilation to improve oxygenation. However, turning the patient's face requires significant physical exertion from medical staff.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A prone facial support device, comprising:

[0007] A supporting arc plate is provided with a base plate on the outer bottom of the supporting arc plate via a supporting column. The two ends of the supporting arc plate are designated as a head end and a tail end. A through head hole is opened on the inner side of the head end of the supporting arc plate, a face hole is opened on the inner side of the middle part of the supporting arc plate, a through tail hole is opened on the inner side of the tail end of the supporting arc plate, and an avoidance opening is opened on one side of the supporting arc plate for inserting a tube.

[0008] A buffer mechanism, mounted on a support arc plate, is used to alleviate pressure on the patient's head and face. The buffer mechanism includes a head support, a face support, a tail support, and a drive mechanism. The top of the head support passes through a head hole to support the area above the ears; the top of the face support passes through a face hole to support the face; and the tail support passes through a tail hole to support the chin area. The drive mechanism, mounted on a base plate, is used to drive the tops of the head support, face support, and tail support to rise and fall respectively.

[0009] An auxiliary support assembly for supporting the patient's shoulders, thereby reducing pressure on the face.

[0010] The aforementioned prone facial support device uses a drive mechanism to alternately support the patient's head and face with the head support arc pad, tail support arc pad, and face support ring pad. This allows the area above the ear, face, and chin to be relieved and relaxed in turn, preventing pressure injuries caused by prolonged pressure on the patient's facial skin. At the same time, it eliminates the need for medical staff to turn the patient's head over, reducing their workload.

[0011] Furthermore, the head support includes a head tube, a head screw, and a head support arc pad. The bottom end of the head tube is rotatably connected to the base plate, the bottom end of the head screw is threaded into the interior of the head tube, and the top end of the head screw is slidably inserted into the head hole and fixedly connected to the outer bottom side of the head support arc pad. The head support arc pad can move up and down within the head hole.

[0012] Furthermore, the face support component includes a first face screw tube, a face screw rod, and a face support ring washer. The bottom end of the face screw rod is rotatably connected to the base plate. The bottom end of the first face screw tube is threaded onto the outer side of the top end of the face screw rod. The top end of the first face screw tube is fixedly connected to the bottom side of the face support ring washer through a support frame, and the face support ring washer can slide up and down inside the face hole.

[0013] Furthermore, the face support also includes a second face screw tube, a face connecting rod, and a face support arc pad. The bottom end of the second face screw tube is slidably inserted into the inside of the top end of the first face screw tube. The top end of the second face screw tube is fixedly connected to the outer bottom side of the face support arc pad, and the face support arc pad can slide through the inside of the face support ring pad. The bottom end of the face connecting rod is fixedly connected to the top surface of the face screw rod, and the top end of the face connecting rod is inserted into the bottom end of the second face screw tube and threadedly connected. Two guide grooves are respectively opened on the two opposite inner walls of the first face screw tube, and two guide blocks are respectively fixedly provided on the two opposite outer walls of the second face screw tube. The two guide blocks are slidably connected by inserting into the two guide grooves respectively. The thread pitch of the first face screw tube is smaller than the thread pitch of the second face screw tube.

[0014] Furthermore, the tail support includes a tail helical tube, a tail screw, and a tail support arc pad. The bottom end of the tail helical tube is rotatably connected to the base plate, the bottom end of the tail screw is threaded into the interior of the tail helical tube, and the top end of the tail screw is slidably inserted into the head hole and fixedly connected to the outer bottom side of the tail support arc pad. The tail support arc pad can move up and down within the tail hole.

[0015] Furthermore, the driving component includes a motor, a rotating shaft, three first bevel gears, and three second bevel gears. The rotating shaft is rotatably mounted on the base plate via a support seat. The output shaft of the motor is fixedly connected to one end of the rotating shaft. The three first bevel gears are fixedly sleeved on the outer surface of the rotating shaft at intervals. The three second bevel gears are respectively fixedly mounted at the bottom ends of the head screw, face screw, and tail screw, and the three first bevel gears are respectively meshed with the three second bevel gears.

[0016] Furthermore, the auxiliary support assembly includes an auxiliary support block, an inflation valve, and two block-shaped airbags. Both ends of the top of the auxiliary support block are provided with receiving grooves, and the two block-shaped airbags are respectively placed in the two receiving grooves. The inflation valve is connected to the two block-shaped airbags through a Y-shaped air pipe for inflation or deflation.

[0017] Furthermore, the top surface and the four edges of the top surface of the auxiliary support block are bonded with soft pads.

[0018] The beneficial effects of this invention are as follows: This prone facial support device, through the forward and reverse rotation of the motor, allows the head support arc pad, tail support arc pad, and face support ring pad to alternately support the patient's head and face, thereby relieving and relaxing the area above the ears, face, and chin area, preventing pressure injuries caused by prolonged pressure on the patient's facial skin; at the same time, the alternating relaxation of the skin under pressure by the patient's prone and side-lying position eliminates the need for medical staff to turn the patient's head, reducing their workload; and the expansion of the block-shaped airbag lifts the patient's shoulders, reducing pressure on the face.

[0035] 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.

[0036] In the description of this invention, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation and positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific way. Therefore, they should not be construed as limitations on this invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] Please see Figures 1 to 3 The present invention provides a prone facial support device, comprising a support arc plate 10, a buffer mechanism 20, and an auxiliary support assembly 30. A base plate 40 is provided on the outer bottom of the support arc plate 10 via a support column 50. The two ends of the support arc plate 10 are designated as a head end and a tail end. A through head hole 11 is provided on the inner side of the head end of the support arc plate 10, a face hole 12 is provided on the inner side of the middle part of the support arc plate 10, and a through tail hole 13 is provided on the inner side of the tail end of the support arc plate 10. A buffer is provided on one side of the support arc plate 10. The inlet 14 is used for inserting the cannula. The buffer mechanism 20 is set on the support arc plate 10 to relieve the pressure on the patient's head and face. The buffer mechanism 20 includes a head support 21, a face support 22, a tail support 23, and a drive 24. The drive 24 is set on the base plate 40 and is used to drive the top of the head support 21, the face support 22, and the tail support 23 to rise and fall respectively. The auxiliary support assembly 30 is used to support the patient's shoulders, thereby reducing the pressure on the face.

[0039] Specifically, when the head support 21 and tail support 23 provide support, the face support 22 lowers to reduce its supporting force, allowing the facial skin to relax. Subsequently, the head support 21 and tail support 23 lower while the face support 22 rises, relaxing the skin in the area above the ears and chin. This allows the skin under pressure during prone or side-lying positions to relax alternately, preventing prolonged pressure.

[0040] In use, the patient's head is placed prone on the inner side of the support arc plate 10, so that the patient's face is facing left or right. At this time, the intubation tube inserted into the patient's face is inserted into the avoidance port 14 to avoid the prone side position affecting the delivery of gas in the intubation tube. At the same time, the area above the ear is placed at the head port 11, the ear area is placed at the face port 12, and the chin area is placed at the tail port 13. Then, the drive component 24 drives the head support component 21 to support the area above the ear, the face support component 22 to support the ear area, and the tail support component 23 to support the chin area, thus buffering the pressure on the skin and avoiding pressure injury caused by prolonged pressure on the area above the ear, the ear area, and the chin area. Moreover, the alternating relaxation of the skin under pressure by the patient's prone side position means that medical staff do not need to turn the patient's head, reducing the workload of medical staff.

[0041] Please refer to the following: Figure 4 The top of the head support 21 passes through the head hole 11 to support the area of ​​the head above the ears. Specifically, the head support 21 includes a head screw tube 211, a head screw 212, and a head support arc pad 213. The bottom end of the head screw tube 211 is rotatably connected to the base plate 40. The bottom end of the head screw 212 is threaded into the interior of the head screw tube 211. The top end of the head screw 212 is slidably inserted into the head hole 11 and fixedly connected to the outer bottom side of the head support arc pad 213. The head support arc pad 213 can move up and down within the head hole 11. The outer surface of the head screw tube 211 is rectangular, and the bottom of the head hole 11 matches the rectangular outer structure of the head screw tube 211, so that the head screw tube 211 can only move up and down and cannot rotate in a circle. Moreover, the top of the head hole 11 matches the outer shape of the head support arc pad 213, which facilitates the retraction of the head support arc pad 213 into the head hole 11.

[0042] When the drive component 24 drives the head screw 212 to rotate, since the head screw 212 is threadedly connected to the head screw tube 211, the head screw 212 drives the head screw tube 211 to move upward, thereby causing the head support arc pad 213 to press against the area above the patient's ear, lifting it up, thus supporting the patient's head and relieving the pressure on the facial skin.

[0043] The tail support 23 passes through the tail hole 13 to support the chin area. Specifically, the tail support 23 includes a tail screw tube 231, a tail screw 232, and a tail support arc pad 233. The bottom end of the tail screw tube 231 is rotatably connected to the base plate 40. The bottom end of the tail screw 232 is threaded into the interior of the tail screw tube 231. The top end of the tail screw 232 is slidably inserted into the head hole 11 and fixedly connected to the outer bottom side of the tail support arc pad 233. The tail support arc pad 233 can move up and down within the tail hole 13. The outer surface of the tail screw tube 231 is rectangular, and the bottom of the tail hole 13 matches the rectangular outer surface of the tail screw tube 231, allowing the tail screw tube 231 to move only up and down and not rotate in a circle. Furthermore, the top of the tail hole 13 matches the outer shape of the tail support arc pad 233, facilitating the retraction of the tail support arc pad 233 into the tail hole 13.

[0044] When the driving component 24 drives the tail screw 232 to rotate, since the tail screw 232 is threadedly connected to the tail helical tube 231, the tail screw 232 drives the tail helical tube 231 to move upward, thereby causing the tail support arc pad 233 to press against the area above the patient's ear, lifting it up and supporting the patient's chin, thus relieving the pressure on the facial skin; moreover, the head support arc pad 213 and the tail support arc pad 233 simultaneously support the area above the patient's ear and the chin area, thus relieving the pressure on the facial skin.

[0045] Please refer to the following: Figure 5 and Figure 6 The top of the face support member 22 passes through the face hole 12 to support the face. Specifically, the face support member 22 includes a first face screw tube 221, a face screw 222, and a face support ring washer 223. The bottom end of the face screw 222 is rotatably connected to the base plate 40. The bottom end of the first face screw tube 221 is threaded onto the outer side of the top end of the face screw 222. The top end of the first face screw tube 221 is fixedly connected to the bottom side of the face support ring washer 223 through a support bracket 229, and the face support ring washer 223 can slide up and down within the face hole 12. The outer surface of the first face screw tube 221 is rectangular, and the bottom of the face hole 12 matches the rectangular outer surface of the first face screw tube 221, so that the first face screw tube 221 can only move up and down and cannot rotate in a circle. Moreover, the top of the face hole 12 matches the outer shape of the face support ring washer 223, which facilitates the retraction of the face support ring washer 223 into the face hole 12.

[0046] While the driving component 24 drives the head support arc pad 213 and the tail support arc pad 233 to provide support, the driving component 24 also drives the face screw 222 to rotate. Since the face screw 222 is threadedly connected to the first face screw tube 221, the first face screw tube 221 moves downward, thereby causing the face support ring pad 223 to separate from the facial skin, so that the facial skin is relieved of pressure for a period of time. The head support arc pad 213 and the tail support arc pad 233 temporarily support the patient's head.

[0047] Preferably, the face support member 22 further includes a second face screw tube 224, a face connecting rod 225, and a face support arc pad 226. The face connecting rod 225 has external threads on its outer side. The bottom end of the second face screw tube 224 is slidably inserted into the interior of the top end of the first face screw tube 221. The top end of the second face screw tube 224 is fixedly connected to the outer bottom side of the face support arc pad 226, and the face support arc pad 226 can slide through the inner side of the face support ring pad 223. The bottom end of the face connecting rod 225 is fixedly connected to... On the top surface of the face screw 222, the top end of the face connecting rod 225 is inserted into the bottom end of the second face screw tube 224 and threadedly connected. Two guide grooves 228 are respectively opened on the two opposite inner walls of the first face screw tube 221, and two guide blocks 227 are respectively fixed on the two opposite outer walls of the second face screw tube 224. The two guide blocks 227 are slidably connected by being inserted into the two guide grooves 228. The arrangement of the guide blocks 227 and the guide grooves 228 allows the second face screw tube 224 to move only up and down. The internal threads of the first face screw tube 221 and the second face screw tube 224 are opposite, causing the second face screw tube 224 to rise while the first face screw tube 221 descends. Furthermore, the thread pitch of the first face screw tube 221 is smaller than the thread pitch of the second face screw tube 224, resulting in the first face screw tube 221 moving a shorter distance than the second face screw tube 224 within the same time frame.

[0048] When the driving component 24 drives the face support ring pad 223 to move downward, the face screw 222 drives the face connecting rod 225 to rotate simultaneously, causing the face connecting rod 225 to drive the second face screw tube 224 to move upward. At this time, the face support arc pad 226 is only in contact with the skin of the face, so that the patient's face skin has a sense of support and feels comfortable. Moreover, since the face support ring pad 223 is located on the outside of the face support arc pad 226, it has a larger support area, increasing the pressure area of ​​the face skin.

[0049] In this embodiment, a soft pad 35 is adhered to the inner side of the supporting arc plate 10 to cushion the pressure on other pressure areas of the head; at the same time, the soft pad 35 has the same holes at the locations of the head hole 11, face hole 12, and tail hole 13. The head supporting arc pad 213, tail supporting arc pad 233, face supporting arc pad 226, and face supporting ring pad 223 are elastic to conform to the patient's skin.

[0050] like Figure 2As shown, in this embodiment, the driving component 24 includes a motor 241, a rotating shaft 242, three first bevel gears 243, and three second bevel gears 244. The rotating shaft 242 is rotatably mounted on the base plate 40 via a support base 245. The output shaft of the motor 241 is fixedly connected to one end of the rotating shaft 242. The three first bevel gears 243 are fixedly sleeved on the outer surface of the rotating shaft 242 at intervals. The three second bevel gears 244 are respectively fixedly mounted at the bottom ends of the head screw 212, the face screw 222, and the tail screw 232, and the three first bevel gears 243 are respectively meshed with the three second bevel gears 244. The motor 241 is a reversible motor.

[0051] When the starter motor 241 rotates forward, the head support arc pad 213, tail support arc pad 233 and face support arc pad 226 are driven to rise through the transmission of the first bevel gear 243 and the second bevel gear 244, while the face support ring pad 223 falls. When the starter motor 241 rotates in reverse, the above is reversed. Moreover, through the forward and reverse rotation of the motor 241, the head and face areas can be alternately pressed, thereby relieving the pressure on the skin.

[0052] like Figure 1 and Figure 7 As shown, in this embodiment, the auxiliary support assembly 30 includes an auxiliary support block 31, an inflation valve 32, and two block-shaped airbags 33. Both ends of the top of the auxiliary support block 31 are provided with receiving grooves 36. The two block-shaped airbags 33 are respectively disposed within the two receiving grooves 36. The inflation valve 32 is connected to the two block-shaped airbags 33 via Y-shaped air tubes 34 for inflation or deflation. A soft pad 35 is adhered to the top surface and the surrounding edges of the top surface of the auxiliary support block 31, which can cushion the pressure on the area where the patient contacts the auxiliary support block 31. The bottom surfaces of the two block-shaped airbags 33 are fixedly adhered to the inner bottom wall of the receiving grooves 36. The uninflated volume of the two block-shaped airbags 33 is smaller than the volume of the receiving grooves 36, facilitating the expansion of the block-shaped airbags 33.

[0053] When the patient's head and face are supported and lifted, if the height of the shoulders is too low, the pressure on the face will increase. Therefore, the two block airbags 33 are inflated through the inflation valve 32 and the Y-shaped air tube 34, so that the two block airbags 33 expand upward, lifting the patient's shoulders and reducing the pressure on the face. At the same time, the height of the shoulders can be adjusted by inflating and deflating the inflation valve 32.

[0054] The working principle of this invention is as follows: In use, the patient lies prone on the inner side of the support arc plate 10 with their head facing to the left or right. The intubation tube inserted into the patient's face is then inserted into the clearance opening 14 to avoid the patient lying on their side affecting the delivery of gas in the intubation tube. At the same time, the area above the ear is placed at the head hole 11, the ear area is placed at the face hole 12, and the chin area is placed at the tail hole 13. Simultaneously, the two block-shaped air bags 33 are inflated through the inflation valve 32 and the Y-shaped air tube 34, causing the two block-shaped air bags 33 to expand upward and lift the patient's shoulders.

[0055] Next, the motor 241 is started to rotate forward. Through the transmission of the first bevel gear 243 and the second bevel gear 244, the head screw 212, the tail screw 232 and the face screw 222 are driven to rotate forward, causing the head support arc pad 213, the tail support arc pad 233 and the face support arc pad 226 to rise. When the motor 241 stops, the head support arc pad 213 supports the area above the ear, the tail support arc pad 233 supports the chin area, and the face support arc pad 226 is slightly in contact with the facial skin, so that the patient's face is not under pressure for a period of time.

[0056] After a period of time, the motor 241 reverses direction, causing the head screw 212, tail screw 232, and face screw 222 to rotate in the opposite direction. This causes the head support arc pad 213, tail support arc pad 233, and face support arc pad 226 to descend, while the face support ring pad 223 rises, providing support to the facial area around the ears. At this time, the head support arc pad 213 and tail support arc pad 233 detach from the skin, temporarily relieving pressure on the skin above the ears and chin, allowing the skin to relax. This forward and reverse rotation of the motor 241 is repeated over a period of time, alternately relieving and relaxing the patient's upper ear, face, and chin areas.

[0057] The beneficial effects of this invention are as follows: This prone facial support device, through the forward and reverse rotation of the motor 241, allows the head support arc pad 213, the tail support arc pad 233, and the face support ring pad 223 to alternately support the patient's head and face, thereby relieving and relaxing the area above the ears, the face, and the chin area, preventing pressure injuries caused by prolonged pressure on the patient's facial skin; at the same time, by allowing the patient's prone and side-lying position to alternately relax the skin under pressure, medical staff do not need to turn the patient's head, reducing their workload; and the expansion of the block-shaped airbag 33 lifts the patient's shoulders, reducing pressure on the face.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
