Without the help of medical staff, the patient can also conveniently control the body state by himself, and achieve the purpose of body flexion and extension exercise, thereby improving the patient's comfort and facilitating rapid recovery.

Description

Technical Field

[0001] The invention belongs to the technical field of medical devices for postoperative patient care, and in particular relates to a postoperative self-help rehabilitation care bed. Background Art

[0002] Paralyzed patients, vegetative patients and other patients have difficulty in moving due to long-term bed rest, so they need specially designed products to perform flexion and extension exercises to prevent and improve complications such as osteoporosis, bedsores, and decreased heart function. Currently, the products used for such people to exercise on the market are all single-use standing frames with relatively single functions. When operating, it takes a lot of people to help or use other transfer equipment to transfer the patient from the nursing bed to the standing frame. Not only does it increase the cost of the patient, but it is also very troublesome in actual operation.

[0003] The existing general patient postoperative care beds need to meet the medical configuration required for daily care and provide support for patients' timely admission or treatment. Such as the mounting required for intravenous injections and the urination and defecation of bedridden patients. However, the current folding beds are very lacking in functionality and generally do not provide lying or sitting care support. Even if some have sitting and lying functions, the structure is complicated, and the human body posture cannot maintain a comfortable state during the process of changing from lying to sitting, or from sitting to lying. Summary of the invention

[0004] In view of the problems of cumbersome operation and inability to control the flexion and extension movement of the person on board in the current postoperative patient care beds, the present invention provides a postoperative self-help rehabilitation care bed which is very simple to operate and can realize the flexion and extension movement of the bed by the patient's self-operation, thereby reducing the burden on nursing staff.

A front running wheel can be installed under the front fixed leg 2, or a running wheel is not installed.

[0016] A rear walking wheel should be installed under the rear movable leg 3. The movable leg is connected with a horizontal sliding rod 11, and a horizontal sliding sleeve 10 is fixed on the lower side of the bed main frame 1, and the horizontal sliding rod 11 is sleeved in the horizontal sliding sleeve 10. At the same time, a symmetrical pulley block is installed inside the horizontal sliding sleeve 10, and the horizontal slider is located between the symmetrical pulley blocks.

[0017] A front extension rod 4 and a rear extension rod 5 are respectively arranged on both sides of the front and rear ends of the bed body main frame 1, and the front extension rod 4 and the rear extension rod 5 are respectively hinged with a front folding plate 8 and a rear folding plate 9 through a pin shaft. The front folding plate 8 and the rear folding plate 9 are used as the front and rear bed boards of the nursing bed after unfolding, and can be kept level with the bed body main frame 1. The front folding plate 8 and the rear folding plate 9 are folded to form the downward baffle and backrest of the seat. The front folding plate 8 is provided with a limit baffle 15 at the hinged part to prevent over-turning and play a supporting role.

[0018] The front folding plate 8 and the rear folding plate 9 are respectively provided with a front drive arm 13 and a rear drive arm 14, and the ends of the front drive arm 13 and the rear drive arm 14 are respectively connected to the two ends of the wire rope 25. After the wire rope 25 is pulled, the corresponding front drive arm 13 or rear drive arm 14 can be driven to swing, thereby controlling the flipping action of the front folding plate 8 or the rear folding plate 9.

[0019] The wire rope 25 is guided by the guide wheel and wound on the winding wheel 12. The guide wheels are respectively arranged at the front and rear sides below the bed main frame 1. The winding wheel 12 is fixed to the lower side of the bed main frame 1 through a support, and a driving mechanism and an automatic locking mechanism are installed on the winding wheel 12.

[0020] The driving mechanism for driving the winding wheel 12 to rotate may be Figure 1 The crank shown can also be driven by a motor.

[0021] See also Figure 3 and Figure 4 As shown, the automatic locking mechanism is a locking disc 42 mounted on the rotating shaft of the winding wheel 12, and the locking disc 42 is elastically connected to a fixed seat arranged on the main frame 1 of the bed. The inner side of the locking disc 42 is connected to a support ring, and the inner end surface of the support ring is provided with anti-skid teeth 38. At the same time, an annular anti-skid groove 39 corresponding to the position of the anti-skid teeth 38 is provided on the end surface of the winding wheel 12. At the same time, a shaft pushing mechanism is provided between the rotating shaft and the inner side surface of the locking disc 42.
