Description

Technical Field

[0001] This application relates to the field of medical care equipment technology, specifically to an adjustable height patient sitting-up support. Background Technology

[0002] In the fields of medical care and home care, people with limited mobility, such as postoperative patients, people with physical disabilities, and elderly people with disabilities, often face great difficulties in independently sitting up from a seated position and need to use assistive devices to change positions. During this process, the support stability, height adjustment flexibility, and ease of use of the assistive devices directly affect the patient's comfort and safety, and also relate to the efficiency of nursing work. Traditional cushion-type assistive devices can only provide basic soft support. Their loose structure and insufficient support strength make it difficult to stably support the weight of the patient's upper body. They are prone to deformation under pressure, causing the patient's body to tilt, increasing the risk of pressure sores. In addition, the height of the cushion is fixed and cannot be adjusted according to the patient's body shape, rehabilitation stage, or sitting angle needs, making them extremely unsuitable.

[0003] Therefore, this application provides a height-adjustable patient sitting-up support to solve the above problems. Utility Model Content

[0004] This application provides an adjustable height patient sitting-up support bracket, which aims to solve the problem that traditional cushion-type assistive tools proposed in the background art can only provide basic soft support, have a loose structure, insufficient support strength, are difficult to stably support the weight of the patient's upper body, and are prone to deformation due to force, causing the patient's body to tilt.

[0005] To achieve the above objectives, this application provides the following technical solution: an adjustable height patient sitting-up assistive support, including a base frame and a plurality of rollers equidistantly installed at the bottom of the base frame, a seat is fixedly installed at the upper end of the base frame, vertical bars are symmetrically installed at the end of the base frame away from the seat, and a standing handrail is fixedly installed at the upper end of the vertical bars; The base frame is equipped with an auxiliary mechanism; The auxiliary mechanism includes limiting rods symmetrically installed on the base frame. The lower end of the standing handrail is provided with a U-shaped frame that fits with the limiting rods. A threaded rod is rotatably connected to the lower end of the standing handrail. A servo motor is installed on the upper end of the base frame. The upper end of the servo motor is fixedly connected to the lower end of the threaded rod. The threaded rod is threaded into the U-shaped frame. An anti-slip sleeve is fitted on the end of the U-shaped frame away from the threaded rod. This solves the contradiction of traditional patient sitting-up assistive supports lacking protection and easily tipping over, or fixed protective railings occupying space and hindering nursing operations. It allows the protective rods to flexibly switch states according to the actual scenario, improving the scenario adaptability of the support.

[0006] Preferably, the U-shaped frame is symmetrically provided with I-shaped sliding grooves, and a first slider and a second slider are slidably connected inside the two sides of the I-shaped sliding grooves respectively. A hinge seat is installed at the lower end of the first slider, and a protective rod is hinged to the hinge seat.

[0007] Preferably, a positioning block is fixedly installed at the end of the protective rod away from the hinge seat, and a round hole is opened on the second slider. The second slider and the positioning block are detachably connected by a threaded pin, which enhances the structural stability of the protective rod in the unfolded protective state and solves the problem that traditional single-hinged protective rods are easy to loosen and cannot effectively prevent patients from rolling over.

[0008] Preferably, each of the I-shaped slides is provided with a round rod inside, and the surface of the round rod near the first slider is provided with a threaded surface. The round rod is rotatably connected to the inside of the U-shaped frame. The round rod and the first slider are threadedly inserted to realize stepless adjustment of the distance between the protective rod and the patient, adapting to the different needs of patients of different body types for the protection range.

[0009] Preferably, the round rod near the second slider is fixedly connected to the interior of the U-shaped frame, and the round rod passes through the second slider.

[0010] Preferably, the round rod near the first slider passes through the U-shaped frame, and a torsion wheel is fixedly installed at one end of the round rod that passes through the U-shaped frame.

[0011] This auxiliary support uses a servo motor to drive the threaded rod to rotate. Utilizing the characteristics of threaded transmission, the U-shaped frame fitted onto the limiting rod rises and falls vertically, thereby adjusting the height of the standing handrail. The anti-slip sleeve increases the friction when the patient grips it, preventing the hand from slipping off. The servo motor controls the height adjustment, which can match the support height requirements of the patient throughout the entire process from "sitting in the chair" to "standing up".

[0012] After the patient stands up, the auxiliary support uses a hand-cranked torsion wheel to drive the round rod to rotate, thereby adjusting the position of the first slider and the protective rod to ensure that the patient can avoid falling backward or to the side. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] This embodiment provides a height-adjustable patient sitting-up assistive bracket, such as... Figure 1-4 As shown, the auxiliary support includes a base frame 1 and several rollers 11 equidistantly installed at the bottom of the base frame 1. A seat 2 is fixedly installed on the upper end of the base frame 1. Vertical rods 3 are symmetrically installed on the end of the base frame 1 away from the seat 2. A standing handrail 4 is fixedly installed on the upper end of the vertical rods 3. An auxiliary mechanism 5 is provided on the base frame 1; The auxiliary mechanism 5 includes limiting rods 54 symmetrically installed on the base frame 1. The lower end of the standing handrail frame 4 is provided with a U-shaped frame 51 that is sleeved with the limiting rods 54. The lower end of the standing handrail frame 4 is rotatably connected with a threaded rod 53. The upper end of the base frame 1 is equipped with a servo motor 55. The upper end of the servo motor 55 is fixedly connected to the lower end of the threaded rod 53. The threaded rod 53 is threadedly inserted into the U-shaped frame 51. The end of the U-shaped frame 51 away from the threaded rod 53 is fitted with an anti-slip sleeve 52.

[0017] Specifically, the base frame 1 moves and adjusts its position via rollers 11, the seat 2 provides a foundation for patient posture support, the vertical rod 3 vertically supports the standing armrest frame 4, forming a force-bearing structure for patients to grasp when sitting up, and in the auxiliary mechanism 5, the servo motor 55 drives the threaded rod 53 to rotate, using the thread transmission characteristics to make the U-shaped frame 51 sleeved on the limit rod 54 rise and fall in the vertical direction, thereby adjusting the height of the standing armrest frame 4. The anti-slip sleeve 52 increases the friction when the patient grasps it, preventing the hand from slipping off. The servo motor 55 controls the height adjustment, which can match the support height requirements of the patient throughout the entire process from "sitting in seat 2" to "standing up". In the electric drive mode, nursing staff do not need to manually lift or adjust the armrest frame. The servo motor 55 is a 400W, 24V DC servo motor 55, which can be matched with a planetary reducer to output sufficient torque to meet the load-bearing requirements of the armrest frame and the patient when grasping. The threaded rod 53 adopts a trapezoidal thread, which is compatible with the internal thread of the U-shaped frame 51.

[0018] The U-shaped frame 51 is symmetrically provided with I-shaped sliding grooves 512. The first slider 514 and the second slider 515 are slidably connected inside the two sides of the I-shaped sliding grooves 512 respectively. The lower end of the first slider 514 is equipped with a hinge seat 516, and a protective rod 56 is hinged on the hinge seat 516.

[0019] More specifically, the I-shaped groove 512 on the U-shaped frame 51 provides a sliding track for the first slider 514 and the second slider 515, limiting their movement path along the groove direction. The first slider 514 is connected to the guard rod 56 through the hinge seat 516. Utilizing the rotational characteristics of the hinge structure, the guard rod 56 can achieve both open and closed states, forming a certain angle with the handrail to prevent the patient from leaning backward and turning to the side.

[0020] A positioning block 561 is fixedly installed at the end of the protective rod 56 away from the hinge seat 516. A round hole is opened on the second slider 515. The second slider 515 and the positioning block 561 are detachably connected by a threaded pin.

[0021] Furthermore, the positioning block 561 at the end of the protective rod 56 is connected to the round hole on the second slider 515 by a threaded pin, forming a two-point support structure between the hinge seat 516 and the positioning block 561, locking the angle of the protective rod 56 after it is unfolded, and preventing the protective rod 56 from flipping and failing due to loosening of a single hinge when the patient leans on it.

[0022] The interior of each I-shaped slide groove 512 is provided with a round rod 513. The surface of the round rod 513 near the first slider 514 is provided with a threaded surface, and the round rod 513 is rotatably connected to the interior of the U-shaped frame 51. The round rod 513 and the first slider 514 are threadedly inserted.

[0023] Furthermore, a round rod 513 is provided inside the I-shaped slide groove 512. The surface of the round rod 513 near the first slider 514 is machined with a threaded surface. The round rod 513 is rotatably connected to the inside of the U-shaped frame 51. It drives the first slider 514 to move along the I-shaped slide groove 512 through threaded transmission, thereby adjusting the length of the protective rod 56 after it is unfolded. The round rod 513 near the second slider 515 is a smooth rod structure and is fixedly connected to the inside of the U-shaped frame 51, providing guide support for the second slider 515 and preventing it from shifting or derailing in the slide groove.

[0024] The round rod 513 near the second slider 515 is fixedly connected to the inside of the U-shaped frame 51, and the round rod 513 passes through the second slider 515. The round rod 513 near the first slider 514 passes through the U-shaped frame 51, and a torsion wheel 511 is fixedly installed at one end of the round rod 513 that passes through the U-shaped frame 51.

[0025] It should be noted that the round rod 513 near the second slider 515 is fixedly connected to the inside of the U-shaped frame 51, serving as a rigid guide shaft when the second slider 515 slides. This restricts the second slider 515 to move only along the axial direction of the round rod 513, preventing it from tilting or derailing within the I-shaped groove 512. This is especially important when the patient leans against the protective rod 56 and generates lateral force, ensuring the stability of the locking structure of the second slider 515 and the protective rod 56. The threaded round rod 513 passes through the U-shaped frame 51, and the torsion wheel 511 installed at its end provides the nurse with an operating component to manually adjust the position of the first slider 514. By cranking the torsion wheel 511, the round rod 513 is driven to rotate, thereby adjusting the position of the first slider 514 and the protective rod 56, ensuring that the auxiliary support can still be used in special circumstances.

[0026] In use, the servo motor 55 drives the threaded rod 53 to rotate. Utilizing the characteristics of threaded transmission, the U-shaped frame 51, which is sleeved on the limiting rod 54, rises and falls vertically, thereby adjusting the height of the standing handrail 4. The anti-slip sleeve 52 increases the friction when the patient grips it, preventing the hand from slipping off. The servo motor 55 controls the height adjustment, which can match the support height requirements of the patient throughout the entire process from "sitting in seat 2" to "standing up". After the patient stands up, the hand crank torsion wheel 511 drives the round rod 513 to rotate, thereby adjusting the position of the first slider 514 and the protective rod 56 to ensure that the patient leans backward and rolls to the side.

[0027] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
