Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a mobile, multifunctional, adjustable body positioning frame. Background Technology

[0002] Retinal detachment refers to the separation of the retinal pigment epithelium and neuroepithelium, resulting in the retina's inability to perform its normal physiological functions. With the continuous development of ophthalmic surgery, vitrectomy combined with silicone oil tamponade is becoming increasingly widely used in clinical practice. It is an effective treatment for patients with complex retinal detachment. After this surgery, patients need to maintain a downward-facing position for a long period of time. The main purpose is to use the buoyancy of silicone oil to press against the retina, maintain vitreous cavity pressure, achieve retinal reattachment, and prevent silicone oil from entering the anterior chamber and causing complications such as high intraocular pressure.

[0003] Patients who have undergone silicone oil tamponade surgery need to maintain a face-down position daily for one month post-surgery, gradually shortening this period based on retinal recovery until the silicone oil is removed. However, prolonged maintenance of this specific position can lead to muscle soreness and numbness in the neck, shoulders, chest, arms, and elbows, affecting post-operative comfort. It can also cause discomfort such as chest tightness, difficulty breathing, and insomnia, as well as negative emotions like irritability and anxiety, significantly impacting recovery. Therefore, positioning aids are necessary when providing face-down care. The use of positioning aids can reduce patient discomfort, alleviating common post-operative symptoms such as increased intraocular pressure, eyelid edema, and incision pain, while also lowering the overall incidence of complications such as retinal detachment recurrence, corneal degeneration, cataracts, and glaucoma.

[0004] Existing positioning aids, such as crescent-shaped pillows for prone positioning, filled U-shaped mattresses, inflatable U-shaped pillows, and novel adjustable positioning pads, all rely on the hospital bed and can only meet the patient's comfort needs while in a prone position. They cannot solve the problem of limb support when the patient changes position. At the same time, while adjustable tables can solve the problem of limb support when the patient changes position, the forced alignment of the head and upper limb support plane when the patient is prone causes the shoulder joint to be in a state of abduction and elevation for a long time, resulting in stress concentration in the shoulder. In addition, the lack of an ergonomic shoulder and neck zone support structure makes it impossible to distribute pressure, which can easily cause shoulder impingement syndrome and pressure sores, seriously affecting postoperative recovery comfort and position maintenance compliance. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the positioning adjustment table used after vitrectomy requires the patient to lie prone with the head and upper limb support planes aligned at a forced height, resulting in the shoulder joint being in a state of abduction and elevation for a long time, causing stress concentration in the shoulder.

[0006] To achieve the above objectives, this application proposes a mobile, multi-functional, adjustable body positioning frame, comprising:

[0007] The three-section support platform components include:

[0008] Head support platform;

[0009] Symmetrical pins are hinged to the arm placement platforms on both sides of the head support platform;

[0010] The three-section support base located at the bottom of the arm placement platform includes:

[0011] A first support seat hinged to the arm placement platform away from the arm placement platform at one end; a second support seat disposed at the bottom of the first support seat; and a height adjustment device disposed between the first support seat and the second support seat;

[0012] The crossbeam assembly disposed at the bottom of the head support platform includes: a base frame rigidly connected to and parallel to the bottom of the head support platform; and a crossbeam disposed between the second support seats and connecting the bottom of the rectangular base frame.

[0013] The adjustment mechanism includes: a dovetail guide groove disposed on the top surface of the first support base; and a slider hinged to the end of the arm placement platform and slidably connected to the dovetail guide groove.

[0014] The mobile multi-functional adjustable positioning frame of this application is linked by a head support platform, an arm placement platform hinged by a pin, and a base with an integrated lifting device. While providing head support, the height of the support seat is controlled by an adjustment mechanism to achieve multi-angle adjustment between the upper limb support plane and the head support plane, so that the arm can be placed at a position lower than the level of the head. This solves the problem in the prior art where the shoulder joint is in a long-term state of abduction and elevation due to the forced alignment of the head and upper limb support plane when the patient is prone.

[0015] Furthermore, to facilitate head fixation, the head support platform has an elliptical head opening at its center.

[0016] Furthermore, to improve comfort when placing the head, the edges of the oval head opening are covered with silicone cushioning pads.

[0017] Furthermore, omnidirectional casters are provided at the bottom of the second support base for convenient adjustment.

[0018] Furthermore, to improve comfort when placing the arm, the surface of the arm placement platform is provided with an ergonomic arc-shaped support groove that extends axially to the far end of the platform.

[0019] Furthermore, in order to improve the wear resistance of the adjustment mechanism, the dovetail guide groove is embedded with a polytetrafluoroethylene wear-resistant bushing, and the surface of the slider is plated with hard chrome, with a fitting gap of 0.1-0.3mm.

[0020] Furthermore, in order to fix the adjustment angle by locking the slider, a limiting groove is provided at the bottom of the dovetail guide groove; the slider is provided with a locking bolt that passes through the top and bottom surfaces, which cooperates with the limiting groove to lock the slider.

[0021] Furthermore, in order to prevent the slider from sliding out of the dovetail guide groove, a baffle is provided at the end of the dovetail guide groove near the head support platform.

[0022] Furthermore, a tabletop is connected to the upper edge of the side wall of the head support platform via a hinge shaft assembly, the hinge shaft assembly including a coaxially arranged pivot and a limiting slot. The tabletop can rotate and unfold to a horizontal state around the pivot and is fixed to the top surface of the head support platform via the limiting slot.

[0023] The beneficial effects of this application are as follows:

[0024] 1. The mobile multi-functional adjustable positioning frame of this application is linked by a head support platform, an arm placement platform hinged by a pin shaft, and a base with an integrated lifting device. While providing head support, the height of the support seat is controlled by the adjustment mechanism to achieve multi-angle adjustment between the upper limb support plane and the head support plane, so that the arm can be placed at a position lower than the horizontal position of the head. This solves the problem in the prior art where the shoulder joint is in a long-term state of abduction and elevation compression because the head and upper limb support plane are forcibly aligned when the patient is prone.

[0025] 2. The slider of this application is provided with a locking bolt that passes through the top and bottom surfaces, which cooperates with the limiting groove to lock the slider. After the angle is adjusted, the angle can be quickly fixed. It is easy to operate, simple in structure, and easy to maintain.

[0026] 3. The slider and groove structure of this application is easy to install, and the wear-resistant bushing can extend the maintenance interval.

[0027] 4. The mobile multi-functional adjustable body support frame of this application is equipped with a flip-up table, which makes it convenient for users to eat while avoiding food contamination of the head support platform. Attached Figure Description

[0040] The following will be combined with the appendix Figures 1-4 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] like Figures 1-3 This illustration depicts a mobile, multi-functional, adjustable positioning frame. To address shoulder compression and achieve multi-angle adjustment, the three-section support platform assembly 1 and the three-section support base 2 of this mobile, multi-functional, adjustable positioning frame work together to achieve multi-angle adjustment of the upper limb and head support plane. The head support platform 11 provides support for the patient's head and is hinged to the arm placement platform 12 on both sides via pins, allowing the arm placement platform 12 to rotate flexibly. The three-section support base 2 at the bottom of the arm placement platform 12 has a first support base 21 hinged to the end of the arm placement platform 12 opposite to the head support platform 11, and a second support base 22 located at the bottom of the first support base 21, with a height adjustment device 23 between them. Adjusting the height adjustment device 23 changes the height of the first support base 21, thereby adjusting the tilt angle of the arm placement platform 12. The base frame 31 in the crossbeam assembly 3 is rigidly connected to the bottom of the head support platform 11, and the crossbeam 32 connects the second support base 22 and the base frame 31, ensuring the stability of the overall structure. The dovetail guide groove 41 of the adjustment mechanism 4 is located on the top surface of the first support seat 21. The slider 42 is hinged to the end of the arm placement platform 12 and slides in the dovetail guide groove 41 to finely adjust the angle of the arm placement platform 12 so that the arm can be placed below the level of the head, thus solving the problem of shoulder compression when the patient is prone.

[0043] After angle adjustment, the adjustment mechanism 4 achieves the angle fixing function. The bottom of the dovetail guide slide 41 is provided with a limiting groove 43, and the locking bolt 44 on the slider 42 passes through the top and bottom surfaces. When the slider 42 slides to the appropriate position, rotating the locking bolt 44 to engage with the limiting groove 43 can lock the slider 42 and fix the angle of the arm placement platform 12. At the same time, the baffle 411 near the end of the dovetail guide slide 41 close to the head support platform 44 can limit the sliding range of the slider 42 and prevent it from sliding out of the dovetail guide slide 41, thus improving the safety of the mobile multi-functional adjustable body position frame. When installing the slider 42, it is only necessary to insert the end of the dovetail guide slide 41 without the baffle 411 installed to complete the installation. This method is simple to operate, has a simple structure, and is easy to maintain and replace.

[0044] As a preferred embodiment, the dovetail guide groove 41 is embedded with a polytetrafluoroethylene wear-resistant bushing, and the surface of the slider 42 is plated with hard chrome. The fit between the two is 0.1-0.3mm. While increasing the wear resistance of the dovetail guide groove 41 and the slider 42, the clearance fit can reduce the friction between the two and prevent the possibility of jamming when the two move relative to each other.

[0045] As a preferred embodiment, the dovetail guide groove 41 can be designed with a small opening and strong self-locking geometry.

[0046] In a preferred embodiment, the arc-shaped support groove 121 of the arm placement platform 12 is provided with a removable sweat-absorbing pad made of medical-grade silicone with a thickness of 5±0.5mm, which is fixed to the bottom of the groove by Velcro.

[0047] As a preferred solution, the arc-shaped support groove 121 of the arm placement platform 12 is equipped with a detachable net, which allows the patient's arm to form a non-contact support with the bottom surface of the arm placement platform 12 in the hot summer, which is more conducive to ventilation.

[0048] Furthermore, the bottom of the second support base 22 is provided with universal rollers 221, wherein the universal rollers 221 are universal rollers 221 with locking function, so that the mobile multi-functional adjustable positioning frame can follow the patient when the patient moves, and after moving to the desired position, the mobile multi-functional adjustable positioning frame can be fixed by locking the universal rollers 221.

[0049] Example 2

[0050] like Figures 1-3 This illustration depicts a mobile, multi-functional, adjustable positioning frame. To enhance the comfort of head and arm placement, the head support platform 11 features an elliptical head opening 111 at its center. This opening conforms to the contours of the patient's head, reducing the contact area between the head and the support platform and alleviating pressure. The silicone cushioning pads 112 at the edges of the opening are elastic and soft, further absorbing head pressure and improving patient comfort. Simultaneously, the arc-shaped support grooves 121 on the surface of the arm placement platform 12 are ergonomically designed and extend axially to the distal end of the platform. They conform to the contours of the arm, providing uniform support, reducing arm dangling and pressure, relieving muscle fatigue and soreness, and improving patient comfort.

[0051] As a preferred option, please refer to Figure 4 , Figure 4 The diagram illustrates the connection between the tabletop 5 and the head support platform 11. The upper edge of the side wall of the head support platform 11 is connected to the tabletop 5 via a hinge shaft assembly 6. The hinge shaft assembly 6 includes a coaxially arranged pivot and a limiting slot. When the user is dining, the tabletop 5 can be rotated 90 degrees so that it is placed on the top surface of the head support platform 11. This provides a hard tabletop for the user to use while dining, improving the stability of placing items. On the other hand, the tabletop protects the head support platform from food contamination.
