Device for leg movement of ICU patient

Abstract

The invention discloses a device for leg movement of an ICU patient. A frame body of a bottom plate of the device is provided with a rotating shaft, and two leg movement mechanisms corresponding to the left and right legs of the ICU patient and allowing the legs to curl and stretch are connected with the rotating shaft side by side; the leg movement mechanisms comprise eccentric cams in shaft connection with the rotating shaft, the protruding edges of the eccentric cams are provided with T-shaped sliding grooves around the circumferences of the eccentric cams, the T-shaped sliding grooves areslidably connected with T-shaped sliding blocks, the T-shaped sliding blocks are connected with the lower ends of lifting rods, the upper ends of lifting rods are provided with leg supporting bodies,the lifting rods are further sleeved with guiding cylinders, and the guiding cylinders are fixed on the frame body; the rotating shaft is further in shaft connection with a first gear, the first gearis meshed with a second gear, the second gear is connected with an output shaft of a motor, the motor is fixed on the frame body, and the motor is electrically connected with a power source through amotor controller. The device for the leg movement of the ICU patient can drive the legs of the patient to rhythmically curl and stretch, thereby moving the legs, the structure is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for moving legs of ICU patients. Background technique [0002] ICU patients lie on the hospital bed and keep one posture for a long time (the supine posture is the majority). Because the patient cannot take care of himself and needs to stay in one posture for a long time, the patient lies down for a long time, which will easily affect the blood circulation of the patient's lower limbs, resulting in edema. Time inactivity will lead to atrophy of leg muscles and ligaments, and the internal function of the whole body will also deteriorate, which will also affect the later recovery and normal walking. At present, the nursing staff or the patient's family members usually hold the patient's leg with their hands and repeat the bending movement , and it takes a certain amount of time to be effective, but this requires the nursing staff to consume a lot of physical strength and t...

[0002] ICU patients lie on the hospital bed and keep one posture for a long time (the supine posture is the majority). Because the patient cannot take care of himself and needs to stay in one posture for a long time, the patient lies down for a long time, which will easily affect the blood circulation of the patient's lower limbs, resulting in edema. Time inactivity will lead to atrophy of leg muscles and ligaments, and the internal function of the whole body will also deteriorate, which will also affect the later recovery and normal walking. At present, the nursing staff or the patient's family members usually hold the patient's leg with their hands and repeat the bending movement , and it takes a certain amount of time to be effective, but this requires the nursing staff to consume a lot of physical strength and time, and also requires the nursing staff to grasp the strength to avoid hurting the patient, so this method of artificially assisted movement is more troublesome and not enough Convenient, resulting in high labor intensity for medical staff or patients' families
