Description

Technical Field

[0001] This utility model relates to the field of assistive devices, and in particular to an assistive device for maintaining a knee-flexed position in a supine position. Background Technology

[0002] The supine position refers to the bed posture adopted by a patient when resting and adapting to medical and nursing needs. Clinically, the supine position is often adjusted according to the patient's condition and treatment needs. A correct supine position plays a positive role in improving patient comfort, treating diseases, alleviating symptoms, preventing complications, and conducting various examinations. Nurses should be familiar with the requirements and methods of various supine positions in clinical nursing work, and assist or guide patients to adopt correct, safe, and comfortable supine positions.

[0003] The supine position with knees bent and the lateral decubitus position are two common lying positions. In the supine position, the patient lies on their back with both knees bent (in a flexed position), both feet flat on the bed, and arms naturally placed at their sides or crossed in front of the chest. If necessary, the patient's legs may need to be separated. Applicable scenarios include abdominal examinations, catheterization, and perineal examinations and treatments. In the lateral decubitus position, the patient lies on their side with the lower leg straight and the upper leg bent (at the knee). Both arms can be extended forward or placed in front of the chest. Applicable scenarios include enemas and rectal examinations and treatments.

[0004] In some scenarios involving the supine or lateral decubitus positions, patients need to maintain a flexed knee position to facilitate examinations or related procedures by the doctor. However, when awake, patients may involuntarily straighten or move their legs due to pain or discomfort during the examination or procedure, making it impossible to maintain a flexed knee position. Under anesthesia, patients may be unconscious or unable to maintain a flexed knee position, causing their legs to unconsciously tend towards a straightening position (especially in the supine position with knees flexed).

[0005] When a patient moves during a medical procedure, it can affect the ongoing examination. For example, the patient's position after movement may no longer meet the optimal requirements for the examination, or the patient's legs may collide with the doctor or related equipment, leading to negative consequences. In severe cases, such as during endoscopy, patient movement may cause injury to the patient. Therefore, when the patient needs to be kept as stably as possible in a flexed knee position in supine or lateral decubitus positions, nurses are usually required to assist in maintaining the patient's position, which requires a relatively large number of personnel. Utility Model Content

[0006] This invention provides an auxiliary brace for maintaining a flexed knee position in a supine position, which can solve the problem of how to maintain a patient's flexed knee position in a supine position in existing auxiliary braces.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figure 1-5As shown in the figure, this utility model provides an auxiliary brace for maintaining a knee-flexed position in a supine position, including a first padding layer 1, a second padding layer 2, a binding member 3, a connecting member 4, and a support member 5. The first padding layer 1 and the second padding layer 2 are preferably made of breathable, flexible cotton material.

[0035] Please see Figure 1-5 In one embodiment of this utility model, a first pad can be provided in the first pad layer 1; the first pad layer 1, i.e. the pad therein, is used to correspond to the patient's knee. The first pad has an arc-shaped structure and is made of sponge material. It can be a flexible sponge layer or a relatively dense rigid sponge layer. It is preferred to be a flexible sponge layer so that the patient has a high degree of comfort.

[0036] Please see Figure 1-5 In one embodiment of this utility model, there are two second pads 2, which are respectively fixedly connected to both ends of the first pad 1. A second protective pad may be disposed within the second pad 2. The second pad 2 and the protective pad within it are used to correspond to the patient's thigh and calf. The second protective pad can be a rectangular structure with an arc-shaped end profile for better fit to the patient's leg. The second protective pad can be a sponge pad. The first protective pad can be a flexible sponge layer or a denser, rigid sponge layer; a denser, rigid sponge layer is preferred for more stable adhesion to the patient's leg during use.

[0037] Please see Figure 1-5 In one embodiment of this utility model, the first padding layer 1 can be a layered structure and can be opened and closed by a zipper. The first pad is disposed inside the first padding layer 1 so that the first pad can be removed. Thus, the first pad can be easily removed when needed. The first padding layer 1 of the outer cover can be directly put into a washing machine for washing, which is convenient and quick, keeps the fixing pad clean and hygienic, prevents bacterial growth, and provides a safe and healthy use environment for patients. Similarly, the second padding layer 2 can also be provided with a zipper structure so that the second pad can be removed.

[0038] Please see Figure 1-5In one embodiment of this utility model, the binding member 3 is fixedly connected to both sides of the second padding layer 2; the binding member 3 is used to bind the second padding layer 2 to the patient's thigh and calf respectively. The binding member 3 can be a Velcro strap of the same length as the second padding layer 2, or it can be multiple straps fixed to both sides of the second padding layer 2. However, since patients' leg thicknesses vary, binding members 3 of the same length as the second padding layer 2 are prone to unstable binding. Using multiple straps is cumbersome and may compress the patient's blood circulation. Therefore, as a preferred example, the binding member 3 is a Velcro strap fixedly connected to both ends of the second padding layer 2. Setting Velcro straps at both ends of the second padding layer 2 can avoid instability caused by different leg sizes. At the same time, using Velcro straps with a certain width facilitates operation, and because of its certain width, it ensures stability while reducing the degree of local pressure on the patient and reducing the impact on the patient's blood circulation.

[0039] Please see Figure 1-5 In one embodiment of this utility model, the connector 4 is fixedly disposed on the side of the second pad 2. Preferably, the connector 4 is disposed on the side outside the patient during use. Multiple connectors 4 can be provided and arranged along the length of the second pad 2. Both ends of the support 5 can be movably connected to the connector 4. During use, the two second pads 2 can be respectively tied to the patient's thigh and calf, and then connected to the connector 4 via the support 5, thereby limiting the posture of the patient's thigh and calf and ensuring that the patient remains stably in a flexed knee position during the examination. During use, the two ends of the support 5 can be connected to the connector 4 at different positions according to needs, such as the patient's body size, knee flexion angle, and desired posture, to adjust the distance between the two second pads 2 and meet different requirements.

[0040] Please see Figure 1-5 In one embodiment of this utility model, since the patient's posture tends to straighten the leg after bending the knee, the support member 5 can be equipped with a traction rope or elastic rope, and its two ends can be configured as hook structures. The connecting member 4 located outside the second padding layer 2 can be configured as a ring structure. The traction rope is hung on the ring structure by the hooks, which provides traction and ensures that the patient remains in a bent knee position.

[0041] Please see Figure 1-5In one embodiment of this utility model, as another example, to ensure stability in limiting the patient's knee flexion position, the support member 5 can also be a rigid rod structure, with both ends configured as hook structures for movable connection to the annular connector 4, or as plug-in structures for push-in connection to the connector 4. As an example, the connector 4 located outside the second padding layer 2 is provided with an arc-shaped push-in sleeve 6 (e.g., Figure 3 The support member 5 has a push-button rod 7 at its end. The space within the push-button sleeve 6 has the same diameter as the push-button rod 7, thus allowing the support member 5 to be movably connected to the connector 4. The portion of the connector 4 located within the second padding layer 2 can be a circular plate structure (e.g., Figure 3 (This is a side view projection), which allows the connector 4 to rotate (the axis of rotation is perpendicular to the surface of the second pad 2).

[0042] Please see Figure 1-5 In one embodiment of this utility model, the support member 5 can be a telescopic rod, thus allowing the length of the telescopic rod to be adjusted according to the patient's specific condition. The telescopic rod may include an outer rod, with inner support rods threaded onto both ends. Rotating the outer rod allows for overall length adjustment of the support member 5. Alternatively, the inner support rod can slide against the outer rod and be locked using a spring pin or other structure, thereby achieving length adjustment of the support member 5.

[0043] Please see Figure 1-5 In one embodiment of this utility model, a connecting part 8 is fixedly provided on one of the second padding layers 2 corresponding to the patient's thigh. The connecting part 8 located outside the second padding layer 2 can be configured as a ring structure or as a snap-fit ​​sleeve 6 structure together with the connecting member 4. By providing the connecting part 8, when it is necessary to limit the posture between the patient's thigh and torso, one end of a traction rope with a hook can be connected to the connecting part 8, and the other end can be hung on the patient's neck, shoulder, or the frame of the bed edge to limit the patient's posture. Alternatively, when the patient is in a supine position with knees bent and the legs need to be kept apart at a certain angle, an additional support rod 9 can be provided, and the two ends of the support rod 9 can be movably connected to the two connecting parts 8 respectively (e.g., Figure 5 This allows for the limitation of the patient's leg-opening angle and posture, ensuring the patient's stability during the examination. The support rod 9 can be connected in the same way as the telescopic rod. The support rod 9 can be configured as an upwardly bent arc-shaped rod structure, thereby providing more operating space between the legs. The support rod 9 can be a telescopic rod with a sliding sleeve connection and its length locked by a spring pin or other structure.

[0044] Please see Figure 1-5In one embodiment of this utility model, at least one side of the first padding layer 1 can be fixedly connected to a protective padding layer 10. That is, the protective padding layer 10 can be disposed on one side or both sides. When disposed on one side, during use, the protective padding layer 10 is located on the side of the knee that the patient needs to protect, generally on the side between the two legs. The length of the protective padding layer 10 is greater than the length of the first padding layer 1, and both ends of the protective padding layer 10 can partially overlap with the binding member 3 and be located inside the binding member 3, that is, during use, it is closer to the patient's skin than the binding member 3. Alternatively, both ends of the protective padding layer 10 can be fixedly connected to the binding member 3. In this way, when the binding member 3 is tied to the patient's leg, it can cause the protective padding layer 10 to conform to the side of the patient's knee, providing protection for that position and protecting the bony prominences on the inner and outer sides of the knee joint from pressure injury. The protective padding layer 10 can be made of a flexible material, a sponge padding layer, or a structure of a sponge padding layer covered with a flexible cotton layer.

[0045] Please see Figure 1-5 In one embodiment of this invention, a memory rebound cushioning layer can be covered on the surface of the second pad 2 that contacts the patient's leg. This cushioning layer is made of slow rebound memory foam, which can automatically shape itself according to the pressure and shape of the patient's leg, disperse pressure, reduce local pressure, reduce the risk of pressure sores, and at the same time enhance the fit between the fixing pad and the legs, further preventing the legs from shifting.

[0046] The first pad 1 and the second pad 2 can be processed separately and then fixedly connected, such as by sewing. Alternatively, they can be directly integrated into a single structure, with fold lines added at appropriate locations for differentiation. The first and second pads within the first and second pads 1 and 2 are respectively designed with curved surfaces and curved contours, making the device ergonomically designed and reducing patient discomfort. Furthermore, the support member 5 and related structures, such as the connectors 4 at both ends, are located on the outer side of the respective pads, avoiding direct contact with the patient's skin and preventing pressure sores or nerve damage. Additionally, the components in this application avoid using metal materials as much as possible, employing plastic or other non-metallic materials to avoid interfering with examination or treatment.

[0047] The working principle of this utility model:

[0048] First, determine the patient's supine position and whether knee flexion needs to be restricted based on the examination items. When the examination requires the patient to maintain a relatively stable position, an auxiliary brace is needed. For example, in the lateral decubitus position, with one leg bent and the other straight, one auxiliary brace is sufficient. If the patient is in a supine position with knees bent and both legs need to be restricted, two auxiliary braces are required. Before or after the patient lies down, align the first pad 1 with the patient's knee, and then align the two second pads 2 at both ends with the patient's thigh and calf, respectively. Then, use the binding 3 to tie the two second pads 2 to the patient's legs. Adjust the patient's posture to the target position, especially the leg posture, and then restrict the patient's knee flexion by adjusting the support 5 to a suitable length or connecting its two ends to the connector 4 at a suitable position. If the patient is in a supine position with knees bent and the angle of the legs needs to be restricted, a support rod 9 of suitable length or a telescopic rod adjusted to an appropriate length can be used, and its two ends connected to the two connectors 8 to restrict the angle of the patient's legs. This allows the patient's legs to remain stable during the subsequent examination without the need for nurses to provide assistance. Once the support brace is set up, the freed-up nurse can help the examiner with equipment handling or other auxiliary tasks. When the examination requires adjusting the patient's posture, the examination equipment is first arranged to ensure that the adjustment process does not affect the patient or the equipment. If the adjustment is minor, the nurse can directly make fine adjustments to the patient's posture. For example, if the knee flexion angle needs adjustment, the position of the connector 4 connected to the support 5 can be adjusted, or the length of the support 5 of the telescopic rod can be adjusted. If the adjustment is significant, one end of the support 5 can be detached first, and then reinstalled after the patient's posture is adjusted to limit the patient's knee flexion and maintain stability during the examination.
