Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a good limb position device for patients with spinal cord injury. Background Art

[0002] Spinal cord injury is a serious disabling disease. Due to long bed rest, it is prone to complications such as pressure sores, spasms, joint contractures, and deep vein thrombosis of the lower limbs. By placing the limbs in a good position, the occurrence of such complications can be effectively reduced. The name of the medical device disclosed in the utility model with application number 201920043749.2 in the prior art is a good limb position for the lower limbs of patients with stroke and / or spinal cord injury, including a bracket part and a connecting device for each joint of the patient. However, this technical solution puts the patient's hemiplegic trunk in a good limb extension position by placing it on each bracket. When the patient's limbs are extended, the support surface provided by this technical solution is relatively scattered and cannot be effectively stressed, and thus cannot assist the patient in turning over. Utility Model Content

[0003] In response to the above technical problems, the technical solution of the utility model proposes a good limb positioning device for patients with spinal cord injury, including a plurality of combinable sub-components, each sub-component being a multi-layer structure with a cavity, comprising a mesh layer and a soft covering layer from the inside to the outside, the mesh layer being provided with a depression suitable for the shape of the limb, the soft covering layer being wrapped around the outside of the mesh layer and extending toward the center of the depression at the edge of the depression.

[0004] As an improvement, the subcomponent includes a head and shoulder supporting portion and an upper limb supporting portion; the mesh layer inside the head and shoulder supporting portion forms a wedge-shaped cavity with a bottom surface and an inclined surface, and a depression suitable for the shoulder joint is provided on the inclined surface of the wedge-shaped cavity.

[0005] As a further improvement, the mesh layer inside the upper limb supporting part forms a cavity with a top surface and a bottom surface, and a protrusion is provided on the top surface on the side close to the patient's head and shoulders. The cavity formed by the mesh layer inside the upper limb supporting part is provided with a through hole, which passes through the protrusion and can accommodate the upper limb to pass through.

[0006] As a further improvement, the subcomponent further comprises a lower limb supporting portion, and the mesh bone layers of the upper limb supporting portion and the lower limb supporting portion are integrally formed.

[0007] As a further improvement, the cavity of the subcomponent is filled with a filler.

[0008] As a further improvement, the surface of the soft coating layer is provided with anti-slip textures or protrusions.

[0009] The above technical solution proposed by the utility model has the following beneficial effects: the cavity structure and the mesh structure make it light in weight and can reliably provide support for the patient's limbs and assist the patient to turn over; multiple sub-components can be assembled into one for use, and each sub-component can also be used separately.

[0012] The significance of good limb positioning for patients with stroke and spinal cord injury is to prevent pressure sores, prevent limb joint spasms, relieve spasms, and maintain good blood circulation. Common lying positions include supine, lateral and prone positions. The patient must be turned over at least once every 2 hours during bed rest. In clinical nursing, in order to maintain the patient's good limb position, a thin pillow is used to support the patient's head so that the height of the thin pillow is equal to the height of one shoulder, a thin pillow is used to support the patient's shoulders to prevent the shoulder joint from retracting, and a soft pillow is used to support the patient's lower body, with the distal end slightly higher than the heart, abducted 45 degrees, the elbow joint is straightened to prevent hyperextension of the elbow joint, and the wrist joint is kept in the dorsiflexion position.

[0013] Next, the content of the utility model is further illustrated by the following examples, but it should not be understood as limiting it. In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0014] Example 1

[0015] The good limb positioning device for patients with spinal cord injury of this embodiment has the following features: Figure 1The structure shown includes a head and shoulder support part 1 (i.e., the first subcomponent) that can be combined, and a subcomponent 2 (i.e., the second subcomponent) that is integrally formed with an upper limb support part and a lower limb support part. Each subcomponent is a multi-layer structure with a cavity (a mesh layer inside and a soft coating layer covering the outside. Based on Example 1, the soft coating layer of some preferred embodiments is a silicone or latex layer, which can play an anti-slip effect). In the head and shoulder support part of Example 1, the mesh layer inside forms a wedge-shaped cavity with a bottom surface and an inclined surface, and a depression 10 suitable for the shoulder joint is provided on the inclined surface of the wedge-shaped cavity. The mesh layer is a mesh skeleton formed by winding or weaving a tough material, and a steel wire woven mesh or a carbon fiber mesh can be used optionally.

[0016] like Figure 1 The upper limb support part 21 has a mesh layer inside the upper limb support part to form a cavity with a top surface and a bottom surface, and the mesh layer inside the upper limb support part is provided with a protrusion 210 on the side close to the patient's head and shoulder. The cavity formed by the mesh layer inside the upper limb support part is provided with a through hole 211 (preferably, its inner wall is also covered with a soft coating layer), and the through hole 211 passes through the protrusion 210 and can accommodate the upper limb (the arm on the pressure-bearing side when the patient lies on his side) to pass through. The upper limb support part is provided with a depression 212 on the outer side of its protrusion to accommodate the patient's palm. Figure 1 The sub-component of this embodiment also includes a lower limb support part 22, wherein the mesh layer of the upper limb support part and the lower limb support part is integrally formed. The lower limb support part 22 is provided with a recess 221 for accommodating and fixing the lower limb, specifically, Figure 1 The recess shown is used to accommodate the fixed lower leg.

[0017] The first subcomponent and the second subcomponent of embodiment 1 are detachably connected by other auxiliary parts such as hook and loop sewn on the outermost layer (fabric layer), and the first subcomponent and the second subcomponent can be separated and used independently when necessary. Preferably, the first subcomponent and the second subcomponent are connected and used at the same time.

[0018] When using the head and shoulder support part of Example 1, place the bottom surface flat on the bed surface. At this time, the patient lies on his side or partially on his side, and the patient's head and shoulders are placed on the inclined surface of the head and shoulder support part, and the patient's shoulder joint is placed at the position corresponding to the depression. After the patient's upper arm is extended, it passes through the through hole of the mesh layer inside the upper limb support part, and the palm is placed in the depression, and the head leans on the protrusion of the upper limb support part. When using the lower limb support part of Example 1, the patient places the lower limb on the side farther from the bed surface when lying on the side into the depression on the lower limb support part. Combined with the accompanying drawings and the explanation of the use of Example 1, it can assist in achieving the lateral and supine positions required for the good limb position placement of patients with spinal cord injury. The inclined surface of the head and shoulder support part helps to assist the patient to turn over.

[0020] Some embodiments are based on embodiment 1, and have the following features: Figure 2 The cross-section of the sub-component includes a mesh layer A, a soft covering layer B, and a fabric layer C from the inside to the outside. The mesh layer A is provided with a recess A1 suitable for the shape of the limb. The soft covering layer B is wrapped around the mesh layer A and extends toward the center of the recess at the edge of the recess (to cushion and fix the limb).

[0021] Based on the above embodiments, the cavity of the sub-components of some embodiments has fillers; the surface of the soft covering layer of some preferred embodiments is provided with anti-slip patterns or protrusions. The fabric layer of some preferred embodiments is an antibacterial fabric layer.

[0022] Although the utility model has been described in detail above by general description and specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the technical solution of the utility model. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the above technical solution all fall within the scope of the protection required.
