Description

Technical Field

[0001] The utility model belongs to the technical field of limb care, and in particular relates to a demonstration device for limb care teaching. Background Art

[0002] Nursing is an applied science, divided into home care and paid nursing. Paid nursing must be carried out in accordance with the relevant provisions of the laws and regulations stipulated by the Ministry of Health, the National Health Commission, and the Ministry of Medical Administration. Basic or routine nursing care must be completed in an organized, purposeful, and planned manner. The patient's body weight and basic condition must be observed and understood. Patients should monitor or obtain medical data based on changes in their condition to assist doctors in completing their treatment. Infusion inspections and education should be strengthened. During clinical nursing teaching, instructors use mannequins for demonstrations, but this does not allow students to truly understand the key points of the movements and the patient's feelings during the teaching process.

[0003] Therefore, in order to solve the above problems, in the prior art, a limb nursing demonstration device for clinical nursing teaching is disclosed with the publication number "CN117037581A". The limb nursing demonstration device for clinical nursing teaching includes a fixed pillow, a trunk fixing seat, an upper limb fixing seat and a lower limb fixing seat. One end of the fixed pillow and the trunk fixing seat can be telescopically connected, the two upper limb fixing seats can be rotatably arranged on both sides of the trunk fixing seat, and the two lower limb fixing seats can be rotatably arranged at the other end of the trunk fixing seat. A groove is provided on the upper limb fixing seat, and a groove is provided on the lower limb fixing seat, and an airbag is provided in the groove.

[0004] Regarding the above-mentioned limb care demonstration device for clinical nursing teaching, although it can realize the demonstration of clinical nursing movements, store the demonstration movements, and allow students to lie in the demonstration device to feel the stretching of the patient's limbs when being cared for, and subsequently achieve better care, it still has the following more obvious defects during use: the device contains multiple movable parts and air bags, etc., which may be more complicated to operate and require the user to have certain mechanical operation knowledge, which may increase the difficulty of learning and use. The air bags and other mechanical parts in the device may require regular maintenance and replacement, which may increase long-term maintenance costs. Although the device allows students to lie in it and feel the stretching of the limbs, the details and feelings involved in real nursing operations may not be fully simulated by this device. The device may not adapt to the needs of patients of different body shapes and heights, limiting its scope of application. The device may lack direct interaction with patients, limiting students' opportunities to learn and practice real nursing skills. Summary of the Invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The following is combined with Figure 1-5 To further explain this application,

[0035] The embodiment of the present application discloses a demonstration device for limb care teaching, comprising a variable posture electric wheelchair 1, a lower limb care exercise demonstration mechanism 2, and an upper limb care exercise demonstration mechanism 3.

[0036] The variable posture electric wheelchair 1 can meet the various posture changes of the human body such as sitting, lying and reclining;

[0037] The lower limb care exercise demonstration mechanism 2 includes two swinging plates 21, a connecting plate 22 connecting the two swinging plates 21, a sponge pad 23 located inside the connecting plate 22 and between the two swinging plates 21 for supporting the foot, and a drive box 24 for driving the swinging plates 21 to rotate. The two swinging plates 21 are bound with a strap A25, which, in conjunction with the sponge pad 23, supports the foot. The strap A25, in conjunction with the swinging plates 21 and sponge pad 23, can better support the foot, increase stability, and ensure greater safety and comfort for the patient during the exercise. During the lower limb care exercise, straps B are bound to the two thighs of the human lower limb. Straps B bound to the thighs can secure the lower limbs in place, preventing them from sliding during the exercise, ensuring effective exercise while reducing friction on the patient's skin.

[0038] The adjustable electric wheelchair 1 is provided with a strap C12 that is tied to the outside of the waist of the human body. The strap C12 tied to the outside of the waist can provide additional support to help maintain body stability, especially for patients with weak waist strength;

[0039] The two swing plates 21 rotate respectively on the inner sides of the two support plates 26 on the front side of the variable posture electric wheelchair 1. The drive box 24 is installed on the outer side of one of the support plates 26. The drive box 24 is also provided with a small gear fixedly connected to the motor output shaft and a large gear fixedly connected to the fixed shaft on one of the swing plates 21. The fixed shaft is rotatably connected to the support plate 26. The small gear is driven to rotate by the motor, and the small gear is engaged with the large gear, thereby driving the support plate 26 to swing.

[0040] The swing plate 21 rotates on the inside of the support plate 26, while the drive box 24 is mounted on the outside of the support plate 26, making the entire mechanism more compact and space-efficient. A small gear within the drive box 24 meshes with a large gear, and the motor drives the small gear to rotate, thereby driving the swing plate 26. This gear transmission design provides smooth movement and reduces mechanical noise and vibration.

[0041] The human body sits on the seat 11 of the variable-posture electric wheelchair 1, with both feet placed on the sponge pad 23. The motor in the drive box 24 drives the swing plate 21 to swing, driving the sponge pad 23 to swing and then driving the lower limbs to be repeatedly lifted and lowered for nursing exercise;

[0042] Lower limb care exercise demonstration mechanism 2: The swing plate 21 is driven by the motor in the drive box 24, and the swing plate 21 can generate reciprocating motion. The connecting plate 22 connects the two swing plates 21, and a sponge pad 23 is placed in the middle to support the patient's feet. The drive box 24 contains a motor and other mechanical components for driving the swing plate 21 to move. The electrically driven swing plate 21 can help patients perform repetitive limb movements and improve exercise efficiency. The variable posture electric wheelchair 1 can adapt to the physical conditions of different patients, meet personalized rehabilitation needs, and enable better experience and demonstration teaching work.

[0043] The upper limb care exercise demonstration mechanism 3 includes two pull rings 31, a drawstring 32 connecting the two pull rings 31, and guide wheels that cooperate with the drawstring 32 for guidance. The upper limb care exercise demonstration mechanism 3 also includes a bracket 33, an inverted U-shaped plate 34 mounted below the bracket 33 via a mounting block 37, and guide wheels that are rotatably mounted on the inner side of the inverted U-shaped plate. The guide wheels include two I-shaped wheels A35 rotatably mounted on the inner side of the left and right ends of the inverted U-shaped plate and guided by the drawstring 32 from below, and a plurality of I-shaped wheels B36 rotatably mounted on the inner top wall of the inverted U-shaped plate and guided by the drawstring 32 from above.

[0044] The inverted U-shaped plate and I-shaped pulleys A35 and B36 effectively guide the pull cord 32, ensuring smooth and safe upper limb exercise. The coordinated movement of I-shaped pulleys A35 and B36 in conjunction with the pull cord 32 provides more stable guidance, reduces vibration during exercise, and enhances the effectiveness of the exercise. Alternatively, the patient can pull one pull ring 31 while the caregiver pulls the other, enhancing engagement. This design increases patient-caregiver interaction, fosters a positive doctor-patient relationship, and strengthens patient trust and cooperation. Different patients may have varying strength and range of motion. Caregivers can adjust the pulling force and range of motion based on the patient's specific needs, personalizing the exercise. Controlling the other pull ring 31 by the caregiver can help prevent injury from overstretching or improper movement, especially for patients with limited strength or coordination.

[0045] The two hands of the human body pull the two pull rings 31 respectively, and the pull rope 32 moves along the guide wheel, thereby achieving alternating nursing exercises for the two upper limbs.

[0046] By simulating normal limb movement, the device can help patients regain muscle strength and joint mobility, promoting recovery. It can also serve as a teaching tool, helping caregivers and students learn and understand limb care and exercise methods through practical application. Actively participating in the exercises can increase patients' enthusiasm and motivation for rehabilitation.

[0047] Utilizing a variable-position electric wheelchair 1 as a base platform, an electrically driven mechanical structure enables lower and upper limb nursing exercises. The variable-position electric wheelchair 1 can be adjusted to sit, lie, or recline positions as needed to accommodate various nursing postures. The lower limb nursing exercise demonstration mechanism 2 utilizes a motor within a drive box 24 to rotate a swing plate 21, which in turn swings a sponge pad 23, thereby performing repeated lifting and lowering exercises on the lower limbs. The upper limb nursing exercise demonstration mechanism 3 utilizes a pull cord 32 and guide wheels to achieve alternating upper limb nursing exercises.

[0048] In general, the design of this nursing teaching demonstration device aims to provide a safe, effective and comfortable environment, so that nursing staff can better guide patients or learners to perform physical exercises during the teaching process, and also enable patients to conduct rehabilitation training independently at home.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
