Description

Technical Field

[0001] This invention relates to the medical field, specifically to a device and method for correcting sleep posture after otolaryngology surgery. Background Technology

[0002] After ENT surgery, in order to reduce edema in the surgical area, promote drainage of secretions, and prevent aspiration, patients are often asked to rest and sleep in a semi-recumbent position with their upper body elevated (such as 30° to 45°).

[0003] However, maintaining this therapeutic position in clinical practice faces significant challenges. Traditional methods mainly rely on raising the head of a regular hospital bed and placing ordinary pillows or foam pads under different parts of the patient's body to try to prevent the body from sliding down. This approach has inherent drawbacks: First, under the influence of gravity, the patient's body will unconsciously slide along the inclined bed towards the feet, causing the lumbar and sacral regions to bear huge shear forces and pressures. This not only causes pain and discomfort but also forces the patient to change to a supine position to relieve pressure, rendering the therapeutic position ineffective and affecting postoperative recovery. Second, ordinary pillows and other supports have a fixed shape, weak support, and are prone to displacement. They cannot be precisely adapted to individual differences such as the patient's height, shoulder width, and leg length, resulting in poor support, low comfort, and the need for frequent adjustments by medical staff, increasing the workload of nursing care. Although there are some medical mattresses or restraint devices for position fixation in existing technologies, their functions are often singular, focusing only on local restraint, lacking a systematic solution that can address the core need of "anti-slip" and achieve multi-point coordination and mechanical linkage. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for correcting sleep posture after ENT surgery, in order to solve the problems of existing devices having limited functions, failing to address the issue of body slippage, and having poor adaptability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a postoperative sleep posture correction device for otolaryngology, comprising a bed frame and uprights fixedly connected to the upper front and rear sides of the bed frame, wherein a leg support mechanism for supporting the patient's legs is provided on the upper front side of the bed frame, and a trunk support mechanism for supporting the patient's torso is provided on the upper rear side of the bed frame.

[0006] The leg support mechanism includes a support seat two placed on the upper rear side of the bed frame. Above the support seat two, there are internal knee support seats distributed in the left and right directions to keep the patient's knee joint in a slightly flexed state and thus generate downward resistance. Support plates are fixedly connected to both ends of the internal knee support seats. Both support plates are provided with height adjustment devices for adjusting the support height of the internal knee support seats. Both sides of the support seat two are provided with positioning devices two for adjusting the front and rear position of the internal knee support seats.

[0007] The trunk support mechanism includes a support seat 1 that abuts against the rear side of support seat 2. Several electric push rods are hinged to the lower side of the support seat, and the other end of the electric push rods is hinged to the bed frame. Axillary support seats for supporting the patient's axillary area are symmetrically arranged on the upper side of support seat 1. A connecting plate is fixedly connected to the side of the axillary support seats on both sides that are far apart from each other. A width adjustment piece for adjusting the distance between the axillary support seats on both sides is provided on the connecting plates on both sides. Adjustment piece 1 for adjusting the front and back position of the axillary support seats is provided on both sides of support seat 1.

[0008] The width adjustment component, position adjustment component one, height adjustment component and position adjustment component two are all equipped with rotating components for driving and controlling their rotation.

[0009] Furthermore, the rotating assembly includes connecting rods that are fixedly connected to the upper end of the bolt column, one end of the pivot pin, one end of the double-acting screw, and the rotating rod of the bevel gear. Each connecting rod has a seat that rotatably passes through it. Each seat is fixedly connected to the upper wall of the movable arch frame three, the outer vertical wall of the movable arch frame four, the side wall of the support seat, and the side wall of the rear section of the corresponding mounting groove of the support seat one. A movable rod slides through the outer end of the connecting rod. A limiting piece is fixedly connected to a section of the movable rod inside the connecting rod. A spring is sleeved on a section of the movable rod between the limiting piece and the outer end wall of the connecting rod. A frustum is fixedly connected to the inner end of the movable rod. Several T-shaped strips are fixedly connected to the outer circumference of the frustum at equal intervals. Several protrusions slide through the side wall of the connecting rod at equal intervals. The corner of the protrusion located inside the connecting rod and near the frustum is set as an inclined surface. The T-shaped strips are slidably connected to the inclined surface of the protrusion through a keyway structure.

[0010] Furthermore, an annular groove is provided inside the insert at the position corresponding to the protrusion, and the inner wall of the annular groove and the outer end of the protrusion are both made of frosted material.

[0011] Furthermore, the bed frame is fixedly connected to the lower side of the four corners, and the lower end of the support leg is equipped with a caster wheel, which is a universal wheel with a brake structure.

[0012] Furthermore, the height adjustment component includes bolts threaded through the right support plate and vertically distributed, and guide pins slidably through the left support plate and vertically distributed. The bolts are rotatably connected to the right movable arch frame three, and the guide pins are fixedly connected to the left movable arch frame three.

[0013] Furthermore, the second adjusting component includes two mounting grooves symmetrically opened on the sides of the second support. A movable arch frame four is slidably embedded in each of the two mounting grooves. A translation gear is rotatably installed in the right movable arch frame four through a pivot pin. A rack is meshed with the lower side of the translation gear and is fixedly connected in the mounting groove two.

[0014] Furthermore, the width adjustment component includes a cavity opened on the rear side of the support base, a bidirectional lead screw is rotatably installed inside the cavity, and a movable arch frame is symmetrically threaded on the bidirectional lead screw. The upper side of the movable arch frame is bent towards the front and parallel to the surface of the support base. A sliding groove is opened on the upper side of the movable arch frame, and a slider is slidably connected in the sliding groove. The slider is fixedly connected to the connecting plate.

[0015] Furthermore, the adjusting component one includes a movable arch frame two fixedly connected to the side of the slider away from the connecting plate. The support one has mounting grooves one on both the left and right sides. The lower side of the movable arch frame two is folded into the mounting groove two and threadedly connected to the translation screw. The translation screw is rotatably installed in the mounting groove one. The mounting groove one is divided into two sections. A bevel gear one is rotatably installed in the rear section. A bevel gear two is meshed with the outer periphery of the bevel gear one. The bevel gear two is fixedly connected to one end of the translation screw.

[0016] Furthermore, the underarm support and the inner knee support are made of rubber-coated sponge, and both surfaces are covered with elastic pads.

[0017] Furthermore, an elastic support bar is fixedly connected to the upper side of the movable arch frame.

[0018] Furthermore, this invention also discloses a method for correcting sleep posture after ENT surgery, the specific steps of which are as follows:

[0019] Step 1: Initial patient positioning: Position the patient on the device with their buttocks at the junction of support seat 1 and support seat 2;

[0020] Step 2: Trunk angle adjustment: Control the extension of the electric push rod to drive the support seat to rise to the target semi-recumbent angle;

[0021] Step 3: Axillary support adjustment: Adjust the distance between the two axillary support seats by operating the rotating component of the width adjustment piece, so that they can stably support the patient's armpit; adjust the front and back position of the axillary support seat by operating the rotating component of the position adjustment piece, and optimize the support for the upper back.

[0022] Step 4: Knee resistance adjustment: Move the inner knee support back and forth by operating the rotating component of the adjustment device two, so that it is aligned with the patient's knee socket; raise or lower the inner knee support by operating the rotating component of the height adjustment device, so that the patient's knee joint is bent at an angle that generates moderate downward resistance.

[0023] Compared with the prior art, the present invention provides a sleep position correction device and method for postoperative ENT surgery, which has the following beneficial effects:

[0024] 1. This invention, through its unique structural design, integrates adjustable underarm support, electrically adjustable backrest, and adjustable knee resistance mechanisms onto a stable bed frame platform. These three components work together to form an integrated anti-slip mechanical closed loop of "upper support, middle support, and lower resistance." This ensures that the patient's body is stably maintained at a preset angle when in a semi-recumbent position, effectively eliminating pressure on the lumbosacral region and postural instability caused by involuntary slippage. More importantly, the device integrates multiple rapid adjustment modules, operated through a unified stretching and rotating component. This allows caregivers to achieve precise matching of shoulder width, leg length, and knee bend angle in a very short time, based on individual patient differences. This represents a leap from "general support" to "personalized customized fit," significantly improving nursing response speed and the quality of postural correction.

[0025] 2. Another beneficial effect of this invention lies in the significant simplification of clinical operation and the fundamental improvement of overall stability. All fine adjustment functions are completed through intuitive mechanical rotating components, with unified operation logic. No electricity or special tools are required, eliminating potential maintenance problems of complex electronic devices in the clinical environment and reducing training costs. The mechanical self-locking mechanism ensures that any adjustment dimension can be reliably maintained after being set, avoiding the drawbacks of traditional pillow support that is easy to shift and requires repeated adjustments. It provides patients with a continuous and stable therapeutic position. At the same time, the modular integrated design of the device makes it an independent mobile unit that can be flexibly adapted to standard hospital beds. This solves the problem of bed occupation and transportation difficulties caused by fixed equipment or scattered accessories in the past, significantly expanding its applicability in different ward scenarios after ENT surgery, and achieving efficient, stable, and convenient high-quality postoperative care.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] As attached Figure 1 To be continued Figure 7 As shown:

[0038] Example 1:

[0039] The present invention provides a postoperative sleep posture correction device for otolaryngology, including a bed frame 1 and a vertical plate 11 fixedly connected to the upper front and rear sides of the bed frame 1. The upper front side of the bed frame 1 is provided with a leg support mechanism 4 for supporting the patient's legs, and the upper rear side of the bed frame 1 is provided with a trunk support mechanism 3 for supporting the patient's torso.

[0040] The leg support mechanism 4 includes a second support seat 41 laid on the upper rear side of the bed frame 1. Above the second support seat 41, there are internal knee support seats 42 distributed in the left and right directions to keep the patient's knee joint in a slightly flexed state and thus generate downward resistance. Both ends of the internal knee support seat 42 are fixedly connected to support plates 421. Both support plates 421 are provided with height adjustment components 43 for adjusting the support height of the internal knee support seat 42. Both sides of the second support seat 41 are provided with adjustment components 44 for adjusting the front and rear position of the internal knee support seat 42.

[0041] The trunk support mechanism 3 includes a support seat 31 that abuts against the rear side of the support seat 41. Several electric push rods 5 are hinged to the lower side of the support seat 31. The other end of the electric push rods 5 is hinged to the bed frame 1. Axillary support seats 32 for supporting the patient's axillary area are symmetrically arranged on the upper side of the support seat 31. A connecting plate 321 is fixedly connected to the side of the axillary support seats 32 that are far apart from each other. A width adjustment component 33 for adjusting the distance between the axillary support seats 32 is provided on both the left and right connecting plates 321. An adjustment component 34 for adjusting the front and back position of the axillary support seats 32 is provided on both the left and right sides of the support seat 31.

[0042] Working principle: The operator drives several electric push rods 5 under the support seat 31 to extend synchronously and smoothly. The lifting force of the push rods acts on the hinge point of the support seat 31, causing it to rotate around the hinge axis with the bed frame 1, thereby driving the entire trunk support area to gradually rise from the horizontal position until it reaches the preset (such as 30°, 45°, 60°) or manually controlled target semi-recumbent position angle and stops. Compared with manual cranks or raising pillows, electric adjustment is more labor-saving, precise, and repeatable, and can achieve slow and stable position changes, greatly improving patient comfort and safety, especially suitable for weak patients after surgery.

[0043] The width adjustment component 33, the position adjustment component one 34, the height adjustment component 43, and the position adjustment component two 44 are all equipped with a rotating component 6 for driving and controlling their rotation.

[0044] The rotating assembly 6 includes connecting rods 61 that are fixedly connected to the upper end of the bolt post 432, one end of the pivot pin, one end of the double-acting screw 331, and the rotating rod of the bevel gear 341. Each connecting rod 61 has a seat 62 that rotatably passes through it. Each seat 62 is fixedly connected to the upper wall of the movable arch frame 3 431, the outer vertical wall of the movable arch frame 442, the side wall of the support 31, and the side wall of the corresponding mounting groove 312 of the support 31. A movable rod 610 slides through the outer end of the connecting rod 61. The movable rod 610 is located at... A limiting piece 69 is fixedly connected to a section inside the connecting rod 61. A spring 68 is sleeved on a section of the movable rod 610 between the limiting piece 69 and the outer end wall of the connecting rod 61. A frustum 66 is fixedly connected to the inner end of the movable rod 610. Several T-shaped strips 65 are fixedly connected at equal intervals around the outer circumference of the frustum 66. Several protrusions 64 slide through the side wall of the connecting rod 61 at equal intervals. The protrusions 64 are located inside the connecting rod 61 and are set as inclined surfaces at one corner near the frustum 66. The T-shaped strips 65 are slidably connected to the inclined surfaces of the protrusions 64 through a keyway structure.

[0045] The insert 62 has an annular groove 63 at the position corresponding to the protrusion 64. The inner wall of the annular groove 63 and the outer end of the protrusion 64 are both made of frosted material.

[0046] The bed frame 1 is fixedly connected to the lower side of the four corners with support legs 2. The lower end of the support legs 2 is equipped with casters 21, which are universal casters with brakes.

[0047] Working principle: The nurse releases the brake on the moving wheel 21, pushes the entire device to a suitable position next to the bed, and then locks the brake again to fix the device. With the assistance of the nurse, the patient moves from the bed or turns around to sit on the device and adjusts their sitting posture by themselves or with the help of others, so that their buttocks are accurately positioned on the boundary line between support seat 1 31 (torso area) and support seat 2 41 (leg area). This step is the physical basis for all subsequent fine adjustments. The mobility of the device ensures that it can flexibly adapt to different bed environments. The clear partition design of support seat 1 31 and support seat 2 41 allows the patient and operator to quickly make a preliminary positioning.

[0048] The height adjustment component 43 includes a bolt post 432 threaded through the right support plate 421 and vertically distributed, and a guide pin 433 slidably through the left support plate 421 and vertically distributed. The bolt post 432 is rotatably connected to the right movable arch frame 3 431, and the guide pin 433 is fixedly connected to the left movable arch frame 3 431.

[0049] Working principle: The operator locates the rotating component 6, which is located above the knee support seat 42 and connected to the upper end of the bolt column 432, and performs the "stretch → rotate → release" operation. The power drives the bolt column 432 to rotate. Since the bolt column 432 and the right support plate 421 are threadedly engaged, and the left guide pin 433 and the left support plate 421 are slidingly engaged (to prevent rotation), the rotational motion of the bolt column 432 is forced to be converted into its own vertical lifting motion. The lifting of the bolt column 432 drives the entire knee support seat 42 and the two side support plates 421 to lift vertically through the moving arch frame 3 431. When it is raised, the patient's lower leg is lifted, the knee joint is passively bent, the bending angle increases, and the resulting downward resistance also increases accordingly. Adjust to an angle where the patient feels moderate resistance and the knee joint is comfortable (usually 15°-30°), and release the movable rod 610 to lock it.

[0050] By adjusting the height to linearly change the resistance, caregivers can make scientific and personalized settings based on the patient's weight, muscle tone, and comfort feedback.

[0051] The adjusting component 44 includes mounting grooves 411 symmetrically opened on the sides of the support 41. Movable arch frames 442 are slidably embedded in the mounting grooves 411 on both sides. A translation gear 443 is rotatably installed in the right movable arch frame 442 through a pivot pin. A rack 441 is meshed with the lower side of the translation gear 443. The rack 441 is fixedly connected in the mounting groove 411.

[0052] Working principle: The operator locates the rotating component 6 located on the side of the support seat 2 41 and connected to the shaft of the translation gear 443, and performs the "stretch → rotate → release" operation. The rotational power drives the translation gear 443 to rotate. Since the gear meshes with the rack 441 fixed in the mounting slot 2 411, the rotation of the gear will be converted into linear motion of the gear axis (i.e., the entire movable arch frame 442) along the direction of the rack 441. The movable arch frame 442 drives the movable arch frame 3 431 on it and the entire knee support seat 42 assembly (including the support plate 421 and the height adjustment component 43) to move back and forth together. Adjust it until the highest point (protrusion apex) of the knee support seat 42 corresponds to about 2 to 3 centimeters above the popliteal fossa on the back of the patient's knee joint. Release the movable rod 610 to complete the locking.

[0053] The knee protrusion structure, which can move back and forth, can precisely position the resistance application point at the optimal biomechanical position above the popliteal fossa according to the thigh length of different patients, ensuring effective downward resistance rather than simply raising the lower leg.

[0054] The width adjustment component 33 includes a cavity 311 opened on the rear side of the support 31. A bidirectional lead screw 331 is rotatably installed inside the cavity 311. A movable arch frame 332 is symmetrically threaded on the bidirectional lead screw 331. The upper side of the movable arch frame 332 is bent towards the front and parallel to the surface of the support 31. A sliding groove 3321 is opened on the upper side of the movable arch frame 332. A slider 3322 is slidably connected in the sliding groove 3321. The slider 3322 is fixedly connected to the connecting plate 321.

[0055] Working principle: The operator locates the rotating assembly 6, located behind the support 31 and connected to the end of the double-acting lead screw 331. By turning the handle 67, the operator pulls the movable rod 610 outward. The frustum 66 and T-shaped bar 65 at the inner end of the movable rod 610 move accordingly. The T-shaped bar 65 slides along the inclined surface inside the protrusion 64, generating a radial force that forces all protrusions 64 to retract inward, causing the frosted surface at their outer end to disengage from the constraint of the inner annular groove 63 of the insert 62. Maintaining this state and rotating the movable rod 610, the power is transmitted to the double-acting lead screw 331 through the connecting rod 61. The rotation of the double-acting lead screw 331 drives the two movable arch frames 332 in the air. Within cavity 311, synchronous linear movements are performed in opposite directions or out of direction. The moving arch frame 332 drives the slider 3322 (and the connecting plate 321 and the axillary support seat 32) to move synchronously through the sliding groove 3321 on it. When the axillary support seats 32 on both sides move to just contact and lightly support the patient's outer armpit, the movable rod 610 is released, the spring 68 returns to its original position, and the movable rod 610 is pushed inward. The T-shaped strip 65 on the frustum 66 moves in the opposite direction, releasing the radial constraint on the protrusion 64. The protrusion 64 pops outward under the rebound action, and its frosted end face is re-locked in the frosted annular groove 63 of the insert 62, achieving self-locking.

[0056] The adjusting component 34 includes a movable arch frame 343 fixedly connected to the side of the slider 3322 away from the connecting plate 321. The support 31 has mounting grooves 312 on both sides. The lower side of the movable arch frame 343 is folded into the mounting groove 311 and threadedly connected to the translation screw 344. The translation screw 344 is rotatably installed in the mounting groove 312. The mounting groove 312 is divided into two sections. A bevel gear 341 is rotatably installed in the rear section. A bevel gear 342 is meshed around the bevel gear 341. The bevel gear 342 is fixedly connected to one end of the translation screw 344.

[0057] Working principle: The operator locates the rotating component 6 located on the side of the support base 31 and connected to the shaft of the bevel gear 341. The operator performs the same "stretching → rotating → releasing" operation. The power drives the bevel gear 341 to rotate through the connecting rod 61. The bevel gear 342, which meshes with it perpendicularly, rotates accordingly, thereby driving the translation screw 344 to rotate. The rotational motion of the translation screw 344 is converted into the linear movement of the moving arch 343 through the threaded pair. Since the moving arch 343 is fixedly connected to the slider 3322, and the slider 3322 slides in the groove 3321 of the width adjusting component 33 (at this time, the width adjusting component 33 is locked, and the slider 3322 can only move along the direction of the groove 3321, that is, the front and back direction), the entire underarm support base 32 assembly is driven to make a precise front and back translation along the surface of the support base 31 to optimize the specific position of the support point from the upper back to the underarm.

[0058] This design utilizes a bevel gear pair to change the direction of power transmission (from lateral rotation to longitudinal rotation), and then converts the rotational motion into precise linear displacement through a lead screw and nut pair. During adjustment, the sliding groove 3321 between the underarm support 32 and the width adjustment component 33 allows it to slide freely back and forth under the condition that the width is locked. Throughout the process, the width adjustment component 33 and the position adjustment component 34 work independently but collaboratively, realizing the decoupled adjustment of the underarm support in both the "width" and "back and forth" dimensions. The operator can quickly set a suitable width and then finely adjust the back and forth position without interference, achieving personalized and three-dimensional adaptation of the underarm area to meet the needs of patients of different heights and ages.

[0059] Example 2:

[0060] This embodiment is basically the same as the previous embodiment, except that the underarm support 32 and the inner knee support 42 are made of rubber-coated sponge, and both are covered with elastic pads 36.

[0061] Working principle: The underarm and knee support seats are made of a composite material of "rubber-coated sponge". While providing necessary support, it ensures that the contact surface is soft, skin-friendly and breathable, taking into account both therapeutic efficacy and comfort during long-term lying down. The elastic pad 36 can ensure elasticity while allowing for quick cleaning of the underarm support seat 32 and the inner knee support seat 42 when the elastic pad 36 is replaced.

[0062] An elastic support bar 35 is also fixedly connected to the upper side of the movable arch frame 332.

[0063] Working principle: The movable arch frame 332 is covered by the elastic support bar 35 to increase the comfort of the patient's arm.

[0064] The specific steps of the method for correcting sleep posture after ENT surgery are as follows:

[0065] Step 1: Initial patient positioning: Position the patient on the device with their buttocks at the junction of support seat 1 31 and support seat 2 41;

[0066] Step 2: Trunk angle adjustment: Control the extension of electric push rod 5 to drive support seat 31 to rise to the target semi-recumbent angle;

[0067] Step 3: Axillary support adjustment: Adjust the distance between the two axillary support seats 32 by operating the rotating component 6 of the width adjustment component 33 to ensure that they are securely supported under the patient's armpit; adjust the front and back position of the axillary support seat 32 by operating the rotating component 6 of the position adjustment component 34 to optimize upper back support;

[0068] Step 4: Knee resistance adjustment: By operating the rotating component 6 of the adjustment component 2 44, move the inner knee support seat 42 back and forth to align it with the patient's knee crease; by operating the rotating component 6 of the height adjustment component 43, raise or lower the inner knee support seat 42 so that the patient's knee joint is bent at an angle that generates moderate downward resistance.

[0069] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
