Description

Technical Field

[0001] This utility model relates to an auxiliary exercise device for preventing deep vein thrombosis in the lower extremities during the care of patients with traumatic brain injury. Background Technology

[0002] Patients with traumatic brain injury often experience slowed venous blood flow in the lower extremities and a significant hypercoagulable state due to prolonged bed rest and limited limb movement. This makes them highly susceptible to deep vein thrombosis (DVT). Complications of DVT, such as pulmonary embolism (PE), pose a fatal risk, while chronic venous insufficiency severely impacts patients' quality of life. Traditional nursing care relies on manual passive movement, wearing elastic stockings, or anticoagulant drugs, but these methods suffer from low efficiency, reliance on manpower, and significant side effects.

[0003] Most existing lower limb massage devices require patients to remain seated or actively move. However, patients with traumatic brain injury cannot meet these requirements due to impaired consciousness or limb paralysis. For example, some devices require the lower limbs to be placed in a fixed space and raised with a strap, but they lack dynamic massage function and are only suitable for patients who actively move, not for patients who are bedridden. Therefore, we provide a lower limb deep vein thrombosis prevention auxiliary exercise device for the care of patients with traumatic brain injury to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary exercise device for preventing deep vein thrombosis in the lower limbs of patients with traumatic brain injury. This device can drive the patient's lower limbs to perform elliptical reciprocating movements on both sides of the support after being restrained by a fixed structure. It can also assist the patient in performing leg flexion and extension exercises after raising the lower limbs, thereby promoting blood circulation and reducing the intensity of manual massage. This addresses the problems mentioned in the background art regarding the adaptation of traumatic brain injury patients due to impaired consciousness or limb paralysis, as well as the lack of dynamic massage function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A lower extremity deep vein thrombosis prevention and auxiliary exercise device for the care of patients with traumatic brain injury includes a bed, a support is vertically installed at one end of the bed, and fixation structures for binding the patient's lower extremities are respectively installed on both sides of the support.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-6As an embodiment of this utility model, the auxiliary exercise device for preventing deep vein thrombosis in the lower limbs of patients with traumatic brain injury includes a bed 1, a support 2 vertically installed at one end of the bed 1, and a fixing structure for binding the patient's lower limbs installed on both sides of the support 2. The fixing structure includes a foot pedal 3, on which an arc-shaped leg receiving groove 4 for placing the patient's lower limbs is vertically provided, and straps 5 for binding the patient's feet and lower limbs are respectively connected to the foot pedal 3 and the arc-shaped leg receiving groove 4. The support 2 is equipped with a drive mechanism, which drives the patient's lower limb fixation structure to perform reciprocating motion with an elliptical trajectory on both sides of the support 2.

[0022] In this embodiment, during use, the patient lies on the bed 1, and the patient's lower limbs are restrained and fixed by the fixed structure. A drive mechanism is set on the bracket 2, which includes a main shaft 6 and a secondary shaft 7 rotatably mounted on the bracket 2. The secondary shaft 7 is provided with swing arms 12 at both ends. One end of the connecting rod 13 is hinged to the swing arm 12, and the other end is slidably connected to the bracket 2 through a sliding component. A fixed rod 16 is provided on the connecting rod 13, and the foot pedal 3 is fixedly mounted on the fixed rod 16. When the main shaft 6 rotates, it will drive the secondary shaft 7 to rotate synchronously. The rotation of the secondary shaft 7 will drive the swing arm 12 to rotate. The rotation of the swing arm 12 will drive the connecting rod 13 to swing, thereby driving the foot pedal 3 on the fixed rod 16 to swing back and forth, that is, driving the fixed structure to swing back and forth. Thus, the driving mechanism can drive the patient's lower limbs to perform elliptical reciprocating movements on both sides of the support 2 after being restrained by the fixed structure. This elevates the patient's lower limbs and assists the patient in performing leg flexion and extension exercises, promoting blood circulation and preventing deep vein thrombosis in the lower limbs.

[0023] As a further embodiment of this utility model, the foot pedal 3 and the arc-shaped leg receiving groove 4 are both made of flexible materials, and the strap 5 is made of elastic strap.

[0024] In this embodiment, the foot pedal 3 and the curved leg receiving groove 4 are both made of flexible materials, and the strap 5 is made of elastic strap to reduce skin friction and the risk of pressure sores. The curved leg receiving groove 4 adopts a curved biomimetic design to improve comfort.

[0025] As a further embodiment of this utility model, the drive mechanism includes a main shaft 6 and a secondary shaft 7 rotatably mounted on the bracket 2. The main shaft 6 and the secondary shaft 7 are connected by a belt mechanism. When the main shaft 6 rotates, it will drive the secondary shaft 7 to rotate synchronously. The secondary shaft 7 is provided with swing arms 12 at both ends. A connecting rod 13 is provided between the swing arms 12 and the bracket 2. One end of the connecting rod 13 is hinged to the swing arms 12, and the other end is slidably connected to the bracket 2 through a sliding component. A fixing rod 16 is provided on the connecting rod 13, and the foot pedal 3 is fixedly installed on the fixing rod 16.

[0026] In this embodiment, the main shaft 6 rotates, and the transmission between the main shaft 6 and the auxiliary shaft 7 is achieved through a belt mechanism. When the main shaft 6 rotates, it will drive the secondary shaft 7 to rotate synchronously. The rotation of the secondary shaft 7 will drive the swing arms 12 on both sides to rotate synchronously. When the swing arms 12 rotate, one end of the connecting rod 13 is hinged to the swing arm 12, and the other end is slidably connected to the bracket 2 through the sliding component. This will drive the connecting rod 13 to reciprocate. Since a fixed rod 16 is set on 13, and the foot pedal 3 is fixedly installed on the fixed rod 16, it will drive the foot pedal 3 to reciprocate, making a reciprocating motion with an elliptical trajectory.

[0027] It should be noted that the trajectory of the connecting rod 13 is closer to a circle than the end of the swing arm 12, and closer to a straight line than the end of the swing arm 12. The trajectory of the swing arm 12 is close to an ellipse when it is near the middle position.

[0028] As a further embodiment of this utility model, a motor 11 is provided on the bracket 2, and the output end of the motor 11 is connected to the main shaft 6 through a coupling to drive the main shaft 6 to rotate.

[0029] In this embodiment, the motor 11 is electrically connected to an external power source via a wire, and starting the motor 11 will drive the spindle 6 to rotate.

[0030] As a further embodiment of this utility model, the belt mechanism includes a first pulley 8 fixed on the main shaft 6 and a second pulley 9 fixed on the auxiliary shaft 7, and the first pulley 8 and the second pulley 9 are driven by a belt 10.

[0031] In this embodiment, when the main shaft 6 rotates, it drives the first pulley 8 to rotate. The first pulley 8 and the second pulley 9 are driven by the belt 10, which in turn drives the second pulley 9 to rotate, thereby driving the auxiliary shaft 7 to rotate.

[0032] As a further embodiment of this utility model, the sliding assembly includes a slide rail 14 fixed on the bracket 2 and a slider 15 slidably engaged on the slide rail 14, with the other end of the connecting rod 13 hinged to the slider 15.

[0033] In this embodiment, the slider 15 is slidably engaged with the slide rail 14, allowing one end of the connecting rod 13 to slide vertically back and forth on the bracket 2.

[0034] As a further embodiment of this utility model, protective railings 17 are provided on both sides of the bed body 1.

[0035] In this embodiment, the guardrails 17 installed on both sides of the bed 1 can limit the movement of the patient's body on both sides when the patient is lying on the bed 1, preventing the patient from falling off the sides of the bed 1 and improving safety during use.

[0036] In use, the patient with traumatic brain injury lies on bed 1. Caregivers place the patient's feet and legs on footrests 3 and curved leg receiving slots 4 respectively, and then bind and secure them with straps 5. The patient's lower limbs are restrained and fixed using this fixing structure. A drive mechanism is installed on the support 2, comprising a main shaft 6 and a secondary shaft 7 rotatably mounted on the support 2. Swing arms 12 are respectively installed at both ends of the secondary shaft 7. One end of a connecting rod 13 is hinged to the swing arm 12, and the other end is slidably connected to the support 2 via a sliding component. A fixed rod 16 is installed on the connecting rod 13, and the footrests 3 are fixedly mounted on the fixed rod 16. The main shaft 6 rotates. The main shaft 6 and the secondary shaft 7 are connected by a belt mechanism. When the main shaft 6 rotates, it drives the secondary shaft 7 to rotate synchronously. The rotation of the secondary shaft 7 drives the swing arms 12 on both sides to rotate synchronously. When the swing arms 12 rotate, one end of the connecting rod 13 is hinged to the swing arm 12, and the other end is slidably connected to the bracket 2 through a sliding component. This will drive the connecting rod 13 to reciprocate. Since a fixed rod 16 is set on 13, and the foot pedal 3 is fixedly installed on the fixed rod 16, it will drive the foot pedal 3 to reciprocate, making a reciprocating motion with an elliptical trajectory. This helps the patient to perform leg flexion and extension activities after the lower limbs are raised, promotes blood circulation, and prevents deep vein thrombosis in the lower limbs. Thus, the driving mechanism can drive the patient's lower limbs to perform elliptical reciprocating movements on both sides of the support 2 after being restrained by the fixed structure. This elevates the patient's lower limbs and assists the patient in performing leg flexion and extension exercises, promoting blood circulation and preventing deep vein thrombosis in the lower limbs.

[0037] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
