Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a three-fold side-turning nursing bed. Background Art

[0002] Nursing beds are generally powered beds, divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, and can be accompanied by family members. They have multiple nursing functions and operation buttons, and use insulated and safe beds. Such as weight monitoring, back-up meals, timed turning alarms, prevention of bedsores, negative pressure urine absorption bedwetting alarms, mobile transportation, rest, rehabilitation (passive movement, standing), infusion and medication, and related prompts. Rehabilitation nursing beds can be used alone or in conjunction with treatment or rehabilitation equipment. They can be used by sick people, severely disabled people, the elderly, and healthy people during hospitalization or home treatment and rehabilitation, in various sizes and forms. Among them, electric nursing beds are more expensive and suitable for patients to control themselves without the help of others; manual nursing beds are moderately priced and require someone to provide simple nursing care.

[0003] Nursing beds can be divided into the following categories according to the number of folding functions of the bed: two-fold, which can realize the long sitting function; three-fold, which can realize the sitting function and can be used as a wheelchair to facilitate the patient's self-movement; four-fold, which can achieve a comfortable sitting position like a chair; with side-folding function, which can realize the side-folding function to avoid the formation of bedsores.

[0004] The side-turning nursing bed is mainly used for patients who cannot move to avoid bedsores. However, conventional side-turning nursing beds have the entire bed surface tilted at a certain angle to achieve the side-turning function. For example, in the invention patent application "A side-turning structure of a hospital bed", application number: CN201510683742.3, the entire upper bed frame is turned sideways by the electric push rod. Even if the side-turning is completed, the patient is likely to fall off the bed, and the patient does not have a comfortable position when turning sideways. Summary of the invention

[0005] The purpose of the present invention is to provide a three-fold side-turning nursing bed, which is used to solve the problems in the prior art that the upper bed frame flips over as a whole, causing the patient to easily fall off the bed and the patient to have no comfortable posture.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A three-fold side-turning nursing bed, comprising a lower bed frame 1 and an upper bed frame, characterized in that: the upper bed frame comprises a pair of three-fold connecting rod mechanisms, the three-fold connecting rod mechanisms comprise a rotating connecting rod 4 and a balancing connecting rod 3 arranged in parallel up and down, both ends of the rotating connecting rod 4 and the balancing connecting rod 3 are connected by a swing connecting seat 5, and the swing connecting seat 5 is rotatably connected to the ends of the rotating connecting rod 4 and the balancing connecting rod 3;

DETAILED DESCRIPTION

[0022] In order to better understand the present invention, the technical solution of the present invention is further described below in conjunction with embodiments.

[0023] like Figure 1-6 As shown,

[0024] A three-fold side-turning nursing bed comprises a lower bed frame 1 and an upper bed frame.

[0025] The upper bed frame includes a pair of three-fold connecting rod mechanisms, which include a rotating connecting rod 4 and a balancing connecting rod 3 arranged in parallel up and down. Both ends of the rotating connecting rod 4 and the balancing connecting rod 3 are connected by a swing connecting seat 5. The swing connecting seat 5 is rotatably connected to the ends of the rotating connecting rod 4 and the balancing connecting rod 3, and together form a parallelogram structure.

[0026] The lower bed frame 1 is provided with a pair of rotating supports 2 arranged symmetrically in the front and rear, and a pair of three-fold connecting rod mechanisms are respectively connected to the corresponding rotating supports 2 (the pair of three-fold connecting rod mechanisms are also arranged symmetrically in the front and rear), wherein the middle parts of the rotating connecting rod 4 and the balancing connecting rod 3 are rotatably connected to the rotating supports 2; the corresponding rotating connecting rods 4 in the front and rear and the swing connecting seats 5 are fixedly connected to the bed board support;

[0027] The two rotating connecting rods 4 in the middle are fixedly connected by two first bed board supports 6, and the two first bed board supports 6 are symmetrically arranged at both ends of the rotating connecting rod 4; the two corresponding swing connecting seats 5 on the sides are fixedly connected by a second bed board support 7.

[0028] The swing connection seat 5 is a triangular structure, and the balancing link 3, the rotating link 4 and the second bed board support 7 are respectively located at three corners.

[0029] It also includes a driving mechanism for driving the rotating connecting rod 4 to rotate, and the driving mechanism is an electric driving mechanism, including an electric push rod 8 and a linkage mechanism; the linkage mechanism includes a linkage rod 9, a first linkage swing arm 10, a second linkage swing arm 11 and a linkage connecting rod 12, and the middle part of the linkage rod 9 is fixedly connected to the first linkage swing arm 10; the lower end of the second linkage swing arm 11 is fixedly connected to the linkage rod 9, the upper end of the second linkage swing arm 11 is rotationally connected to the lower end of the linkage connecting rod 12, and the upper end of the linkage connecting rod 12 is rotationally connected to the first bed board support 6; the lower end of the first linkage swing arm 10 is rotationally connected to the left side of the lower bed frame 1, and the two ends of the electric push rod 8 are rotationally connected to the upper end of the first linkage swing arm 10 and the right side of the lower bed frame 1 respectively. A second linkage swing arm 11 is provided at each end of the linkage rod 9, and the first linkage swing arm 10 is located in the middle of the linkage rod 9.

[0030] The rotation connection can be a shaft connection, a hinge connection, a single-end pin connection, etc.

[0031] The rollover process of a three-fold rollover nursing bed:

[0032] (1) Figure 5 As shown, the electric push rod 8 is located in the middle position, the rotating connecting rod 4, the swing connecting seat 5, the first bed board support 6, and the second bed board support 7 are located in the same horizontal plane, and the nursing bed is in a normal state.

[0033] (2) Figure 4 As shown, the electric push rod 8 is retracted to the shortest state, and the retraction of the electric push rod 8 drives the linkage rod 9 to rotate downward, and the second linkage swing arm 11 also rotates downward, and the linkage link 12 moves downward and the angle between it and the second linkage swing arm 11 is reduced, driving the balancing link 3 and the rotating link 4 to rotate counterclockwise, and the swing connection seat 5 on the left side keeps descending horizontally (wherein, since the balancing link 3 and the rotating link 4 rotate synchronously, the connecting line of the ends on the same side is always vertical, so the swing connection seat 5 will not rotate); in the reverse direction, the swing connection seat 5 on the right side keeps rising horizontally. Flipping to the left is realized.

[0034] (3) Figure 6 As shown, the electric push rod 8 is extended to the longest position, in the opposite direction of (2), to achieve right-side flipping.

[0035] The above description is only an application embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
