Description

Technical Field

[0001] This utility model relates to the field of medical care, and more particularly to the field of massage devices, specifically a lower limb massage device for bedridden patients. Background Technology

[0002] Prolonged bed rest leads to significantly slowed venous return in patients with limited lower limb mobility, resulting in blood stasis that can induce deep vein thrombosis (DVT). If a thrombus breaks off, it can cause a fatal pulmonary embolism. Simultaneously, continuous pressure on local tissues accelerates pressure ulcer formation, while lack of mechanical stimulation causes disuse atrophy and joint contractures, severely impacting patient recovery. Clinical studies have shown that regular massage intervention of the lower limbs can promote venous and lymphatic return through external mechanical stimulation, relieve muscle spasms, improve local tissue metabolism, and reduce the risk of pressure ulcers. It is a safe, convenient, and inexpensive physical prevention method.

[0003] However, existing nursing methods cannot fully achieve the above-mentioned effects. Manual massage relies entirely on the operation of nursing staff, which is labor-intensive, time-consuming, and difficult to standardize in terms of intensity and frequency, making it impossible to guarantee a continuous and regular intervention effect. Most lower limb massage devices on the market are designed for people who can sit, which has obvious limitations: First, they are bulky and heavy, and cannot be directly adapted to the narrow space of a hospital bed; second, they only massage one area and lack an integrated device that can simultaneously cover the soles of the feet and calf muscles, while the synergistic massage of acupoints on the soles of the feet and calf muscles has a synergistic effect on promoting overall blood circulation; third, the drive structure is complex, and multifunctional devices often require multiple motors to drive them separately, resulting in high power consumption, high noise, and high failure rate; fourth, they lack leg shape self-adaptation ability, and the fixed spacing of the massage heads or rigid supports cannot adapt to the leg shapes of different patients, which not only affects the massage fit, but may also cause discomfort due to improper pressure. Air wave pressure therapy is currently the mainstream auxiliary device for the clinical prevention of deep vein thrombosis. Its core principle is to apply pressure to the air bladder in a gradient manner and compress it as a whole, which has a significant effect on preventing deep vein thrombosis. However, due to its strong enveloping feeling, some patients feel stuffy and uncomfortable, resulting in a poor comfort experience.

[0004] Therefore, there is an urgent need for a compact, bed-fitting lower limb massage device that can simultaneously massage the soles of the feet and calves, has leg shape adaptability, and is easy to operate, so as to systematically and standardizedly replace manual care, effectively prevent lower limb complications in bedridden patients, and reduce the burden of nursing care.

[0023] In a preferred embodiment of this utility model, the foot massage module further includes a base and a plurality of massage beads, the plurality of massage beads being mounted on the base, the base being mounted on a vertical rod, and the vertical rod driving the base to move.

[0024] In a preferred embodiment of this utility model, the leg massage module includes a horizontal rod and a horizontal clamp, the control box also includes a vertical guide groove, the horizontal clamp is installed on the horizontal rod, the horizontal rod is installed on the side of the vertical guide groove, the motor actuation shaft slides up and down in the vertical guide groove, and the horizontal rod supports horizontal reciprocating motion.

[0025] In a preferred embodiment of this utility model, the leg massage module further includes a leg support and a spring guard plate. The spring guard plate is mounted on the leg support, and the leg support is mounted on a horizontal bar. The horizontal bar drives the leg support to move.

[0026] In a preferred embodiment of the present invention, the control box further includes a motor bracket, and the motor is mounted on the motor bracket.

[0027] In a preferred embodiment of the present invention, the device further includes a power supply and a switch. The power supply is installed inside the control box, and the switch is installed on the side of the control box and connected to the power supply.

[0028] In a specific embodiment of this invention, the lower limb massage device for bedridden patients is motor-driven and can simultaneously perform rolling massage on the soles of the feet and calves. The product consists of four parts: a foot massage module, a leg massage module, a power supply, and a control box. The two massage components can move in a fixed direction to achieve the massage purpose.

[0029] The control box contains the mounting and control components of the massage device. Power comes from a motor that drives the massage devices on both sides via bevel gears.

[0030] Firstly, the vertical rod, controlled by a vertical clamp, can only move vertically. The vertical rod and the horizontal guide groove are an integrated structure. Then, the motor actuating shaft rotates along with the fixed motor shaft, sliding within the horizontal guide groove. Due to the vertical clamp, it can only perform vertical up-and-down reciprocating motion, thus driving the base and foot massage beads to massage the soles of the feet. The leg massage module works on a similar principle, except the vertical motion is changed to horizontal reciprocating motion, achieving the purpose of leg massage. Furthermore, considering the varying leg shapes of patients, we designed springs on the connecting rods on both sides of the leg massage beads. This allows the massage beads to adaptively adjust to the patient's leg shape when they place their lower legs on the massage beads, ensuring maximum leg fit and enhancing the patient's massage experience.

[0031] The movement of this device can be divided into two dimensions: horizontal and vertical, both generated by the force produced by the motor actuating shaft. First, let's describe the individual function of each component: Vertical rod: The vertical rod and the horizontal guide groove are integrated into one structure. The vertical rod is a square guide rod that can slide vertically. Vertical clamps: provide a guide groove for fixing the vertical rod and allow it to slide only up and down, secured by two clamps; Horizontal guide groove: When the motor drives the shaft to make a circular motion, it drives the end of the vertical rod to form a horizontal guide groove. In this guide groove, due to the rotation of the shaft, the shaft provides the guide groove with forces in both vertical and horizontal directions. The vertical force forces the vertical rod to slide up and down, while the horizontal force causes the shaft to slide within the guide groove. The motor's fixed shaft rotates in place and is the center of the motor's rotation. Motor arm: Connects the motor fixed shaft and the motor actuating shaft, providing a lever arm for the rotation of the motor actuating shaft; Motor actuation shaft: It moves in a circle with the motor fixed shaft as the center and the length of the motor arm as the radius. Simultaneously, guide grooves connecting the vertical and horizontal bars provide power in two directions for their sliding.

[0032] like Figure 5 As shown, one end of the spring is a fixed seat with a flange structure, and the spring is inserted into the fixed seat; the other end is an L-shaped right-angle sleeve, and the spring is inserted into the right-angle sleeve. Both are sleeve connections.

[0033] This device can massage the lower limbs and perform reciprocating movements in two directions, providing adaptive massage for the calves.
