Description

Postoperative self-help rehabilitation nursing bed

Technical field:

The invention belongs to the technical field of postoperative patient nursing medical equipment, and in particular relates to a postoperative self-help rehabilitation nursing bed.

Background technique:

Paralyzed patients, vegetative patients and other patients need specially designed products to perform flexion and extension exercises due to long-term bed rest and inconvenient movement, so as to prevent and improve complications such as osteoporosis, decubitus ulcers, and cardiac function decline. The products currently on the market that are used for this group of people to exercise are all standing stands that are used alone and have a relatively single function. During operation, if you want to transfer the patient from the nursing bed to the standing stand, you need a lot of people to help together or to complete it with the help of other transfer equipment. Not only increased the patient's expenses, but also very troublesome in actual operation.

The existing postoperative nursing beds for ordinary patients need to meet the medical configuration required for daily nursing, and provide support for the timely admission or treatment of patients. Such as the mounting required for drip injection, the urine and stool of bedridden patients. However, the current folding beds are lacking in functionality, and generally do not provide horizontal or sitting nursing support. Even if some have sitting and lying functions, the structure is complex, and during the process from lying to sitting, or from sitting to lying, the posture of the human body cannot maintain a comfortable state.

Invention content:

The present invention aims at the troublesome operation and the inability to control the flexion and extension movement of the existing postoperative patient care bed, and provides a postoperative self-service rehabilitation nursing bed that is very simple in operation and can be operated by the patient to realize the flexion and extension of the bed body, thereby Reduce the burden on nursing staff.

Technical solution: A postoperative self-help rehabilitation nursing bed, including a bed main frame, a folding structure and a driving mechanism. The lower end of the bed main frame is provided with front fixed legs and rear movable legs, and the front and rear of the bed main frame There are front extension rods and rear extension rods on both sides of the end respectively, and the front extension rods and the rear extension rods are respectively hinged with a front folding plate and a rear folding plate through pin shafts. The driving arm, the ends of the front driving arm and the rear driving arm are respectively connected to the two ends of the steel wire rope, and the steel wire rope is wound on the winding wheel after being guided by the guide wheel. The winding wheel is fixed on the lower side of the main frame of the bed through the support, and the driving mechanism and the automatic locking mechanism are installed on the winding wheel; the automatic locking mechanism is that a locking disc is set on the rotating shaft of the winding wheel, The locking disc is elastically connected with the fixing seat provided on the main frame of the bed body; the inner surface of the locking disc is connected with a support ring, and the inner end surface of the support ring is provided with anti-skid teeth, and at the same time, there are anti-skid teeth on the end face of the winding wheel. Corresponding annular anti-skid groove, meanwhile, a shaft pushing mechanism is arranged between the rotating shaft and the inner surface of the locking disc; the shaft pushing mechanism is fixed with a shaft pushing active fitting on the rotating shaft along the The outer side of the shaft is provided with a shaft push inclined surface, and the inner surface of the locking disc is provided with a shaft pushed passive fitting. The shaft pushed passive fitting contains a shaft pushed inclined surface chute. Pushing the active fitting can never break away from the shaft pushing inclined plane chute of the shaft pushing the passive fitting.

Movable legs are arranged at the lower end of the main frame of the bed body, and walking wheels are installed under the movable legs. The movable leg is connected with a horizontal sliding rod, and a horizontal sliding sleeve is fixed on the lower side of the main frame of the bed body, and the horizontal sliding rod is set in the horizontal sliding sleeve; A driven pulley is installed coaxially with the gear, and a rack is arranged on the side wall of the horizontal slide bar, and the rack is engaged with the gear; a driving pulley is installed on the rotating shaft of the driving mechanism, and the driving pulley and the The driven pulley is driven by a belt.

Symmetrical pulley blocks are installed inside the horizontal sliding sleeve, and the horizontal sliding block is located between the symmetrical pulley blocks.

An ankle pulley is provided at the end of the front flap. A headrest and a headrest height adjustment mechanism are arranged above the rear folding plate.

The present invention has the following beneficial effects: the present invention can realize the unfolding and folding of the nursing bed through shaking of the hand wheel or electric drive, and only one operation is required. An automatic locking mechanism is set, which can stop and keep locking at any angle, so that the nursing bed can provide self-service operation for postoperative patients. Without the help of medical staff, the patient can easily control the body state and achieve the purpose of body flexion and stretching, which improves the patient's comfort and facilitates rapid recovery. The present invention also provides a synchronous unfolding structure for the bottom traveling wheels. After the entire nursing bed is unfolded, the lower traveling wheels also unfold accordingly, thereby improving the stability of the nursing bed.
