Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training restraint device technology, and in particular to a protective blanket for wheelchair functional training. Background Technology

[0002] Neurocritical care patients are often severely ill, experiencing altered consciousness, limb dysfunction, and requiring multiple mechanical ventilations and invasive catheters. They are frequently bedridden, increasing the risk of complications such as hypostatic pneumonia and ICU-AW, significantly impacting their prognosis and post-discharge quality of life. Early ambulation and wheelchair training can promote neuromuscular function recovery and shorten the duration of mechanical ventilation and hospital stay.

[0003] Currently, during early mobilization of critically ill patients undergoing wheelchair functional training, the severity of their condition, impaired consciousness, and the presence of multiple high-risk catheters increase the risk of catheter-related infections. Multiple life support lines (such as intravenous catheters, urinary catheters, and drainage tubes) can slip unintentionally due to the patient's unconscious pulling or changes in position. Furthermore, patients with limb dysfunction or agitated states are prone to falling from the wheelchair, potentially leading to secondary head injuries and severely impacting patient prognosis. Traditional wheelchairs and ordinary blankets offer limited functionality, failing to prevent sputum contamination and lacking both a catheter fixation system and proper body positioning.

[0004] Therefore, we propose a protective blanket for wheelchair function training to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective blanket for wheelchair function training.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Reference Figure 1 and Figure 2 A protective blanket for wheelchair function training includes a blanket body 1. One side of the blanket body 1 has an upper limb fixation liner 2. Below the upper limb fixation liner 2 is a chest fixation elastic band 3. Below the chest fixation elastic band 3 are two symmetrically located lower limb fixation liners 4. The blanket body 1 has two symmetrically located strip-shaped openings 5 ​​running through both sides. Several Velcro straps 6 are located on the sides of the strip-shaped openings 5. The edges of the blanket body 1 are fitted with a connecting mechanism for connection to the wheelchair. The blanket body 1 is fixed to the wheelchair through the connecting mechanism, achieving restraint and fixation of the patient, thereby protecting the patient undergoing wheelchair function training and preventing the patient from slipping and falling.

[0027] For the above example, those skilled in the art should know that when implementing the above technical solution, the entire blanket body 1 is made of cotton cloth and has insulation material inside.

[0028] Neurosurgical critical care patients often experience altered consciousness, limb dysfunction, and restlessness, posing a high risk of self-extubation. By using upper limb fixation liner 2, this can be used when patients are restless. The method of use is to insert both hands into the upper limb fixation liner 2 and tie them together with restraint straps, which can prevent patients from extubating and at the same time maintain the functional position of both upper limbs.

[0029] The two lower limb fixation liners 4 allow the patient's legs to be inserted, thus fixing the lower limbs and maintaining their functional position.

[0030] The combination of the upper limb fixation liner 2 and the two lower limb fixation liners 4 allows the blanket body 1 to maintain the functional position of the limbs, promoting the effectiveness of functional training. At the same time, it provides restraint and protection for the limbs, preventing injury caused by patient extubation.

[0031] The strip opening 5 and several Velcro straps 6 can protect and fix the pipeline wires, prevent the pipeline from slipping, and facilitate pipeline management when used with the blanket body 1.

[0032] For the above examples, those skilled in the art should know that when implementing the above technical solutions, the upper limb functional position refers to the body position in which the upper limb can perform optimal functional activities under a specific posture, and the lower limb functional position refers to the body position in which the lower limb can maintain optimal functional activities under a specific posture.

[0033] As a technical optimization of this utility model, the upper limb fixing liner 2 is provided with a first cotton pad 7 inside, which is used to protect the upper limb. The two lower limb fixing liners 4 are also provided with a second cotton pad 8 inside, which is used to protect the lower limb.

[0034] As a technical optimization of this utility model, the chest-fixing elastic band 3 is horizontally arranged on the blanket body 1, and the length of the chest-fixing elastic band 3 is longer than the width of the blanket body 1. The chest-fixing elastic band 3 can keep the body in a functional position, promote the upper body, especially the lungs, to remain vertical and horizontal, and promote the effectiveness of lung breathing exercises.

[0035] For the above examples, those skilled in the art should know that when implementing the above technical solutions, the upper body functional position refers to the body position in which the upper body can perform optimal functional activities in a specific posture.

[0036] As a technical optimization of this utility model, a waterproof layer 9 is provided on the side of the blanket body 1 away from the upper limb fixing liner 2 and the lower limb fixing liner 4. The edge of one end of the waterproof layer 9 is semi-circular and folded to the other side of the blanket body 1. The waterproof layer 9 facilitates wiping phlegm and prevents contamination.

[0037] For the above example, those skilled in the art should know that when implementing the above technical solution, the waterproof layer 9 is composed of waterproof material.

[0038] As a technical optimization of this utility model, the connecting mechanism includes several straps 10, which are arranged in multiple pairs. A pair of straps 10 is fixedly provided at each of the four corners and on both sides of the blanket body 1. The multiple pairs of straps 10 can fix the blanket body 1 to the wheelchair, thereby achieving the effect of subsequently restraining the patient.

[0039] Reference Figure 3 , Figure 4 and Figure 5 The connecting mechanism also includes two clamping parts, with a connecting rod 11 between the two clamping parts. Both ends of the connecting rod 11 are telescopically connected to telescopic rods 12. Both telescopic rods 12 are fixed with straps 13 that can be tied to the wheelchair. The connecting parts include connecting seats 14. The two connecting seats 14 are fixedly connected to the two connecting rods 11 respectively. Two bent clamping blocks 15 are symmetrically arranged and rotatably connected on the connecting seats 14. An inverted U-shaped block 16 is provided between the two bent clamping blocks 15. The inverted U-shaped block 16 is fixedly connected to the connecting seat 14. A screw 17 is threaded through the inverted U-shaped block 16. A rubber extrusion block 18 is fixed at the lower end of the screw 17. The rubber extrusion block 18 is located between the two bent clamping blocks 15. Rotating the screw 17 of the clamping component moves the rubber compression block 18, causing it to press against one end of the two bent clamping blocks 15. This increases the distance between those ends of the two bent clamping blocks 15 and decreases the distance between the other ends. The reduced distance clamps the blanket body 1, ensuring a stable clamping and positioning effect. The rubber compression block 18 is elastic, effectively pressing against the two bent clamping blocks 15. Once it reaches the desired position, it can no longer press or move, ensuring the two bent clamping blocks 15 remain clamped. The distance between each pair of clamping components can be adjusted via the telescopic rod 12, allowing for flexible selection of the blanket body 1's edge for clamping and positioning. The two straps 13 securely fasten the blanket body 1 to the wheelchair.

[0040] As a technical optimization of this utility model, each of the two bending clamping blocks 15 is provided with a limiting groove on one side opposite to the other. Both ends of the rubber extrusion block 18 are positioned and limited by the limiting groove, which ensures that the rubber extrusion block 18 moves stably.

[0041] In this invention, the working principle of the device is as follows:

[0042] This device serves to stabilize the body and limbs during wheelchair function training, maintaining the limbs in a functional position and securing tubing. Specifically, the blanket body 1 is secured to the wheelchair via multiple pairs of straps 10, restraining and protecting the patient during training and preventing slippage and falls. Alternatively, the blanket body 1 can be clamped along its edge for subsequent wheelchair connection. Rotating the screw 17 of the clamping device moves the rubber compression block 18, which in turn compresses one end of two bent clamping blocks 15, increasing the distance between those ends and decreasing the distance between the other ends. This reduced distance clamps the blanket body 1 in place. The screw 17 has a self-locking function, ensuring stable clamping and preventing detachment. Furthermore, the spacing between each pair of clamping members can be adjusted via the corresponding telescopic rod 12, which not only allows for flexible selection of the edge of the blanket body 1 for positioning and clamping, but also increases the length of the clamping edge to improve clamping stability. The two subsequent straps 13 can then be used to secure the wheelchair.

[0043] Meanwhile, to address the high risk of patients pulling out the tubes themselves, upper limb fixation liners 2 can be used. When the patient is agitated, upper limb fixation liners 2 can be used by inserting both hands into the liners and securing them together with restraint straps. This prevents the patient from pulling out the tubes and maintains the functional position of both upper limbs. The two lower limb fixation liners 4 allow the patient's legs to be inserted, effectively fixing the lower limbs and maintaining their functional position. The combination of upper limb fixation liners 2 and two lower limb fixation liners 4 ensures that the blanket body 1 maintains the functional position of the limbs, promoting the effectiveness of functional training. It also provides restraint and protection for the limbs, preventing the patient from pulling out the tubes and causing injury. The strip-shaped opening 5 and several Velcro straps 6 protect and secure the tubing and wires, preventing slippage. Used in conjunction with the blanket body 1, this facilitates tubing management.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
