Description

Technical Field

[0001] This invention relates to the field of nursing bed technology, and specifically to a nursing bed and its method of use. Background Technology

[0002] In recent years, the aging population has become increasingly apparent, leading to a rise in patients requiring long-term bed rest for treatment and rehabilitation, thus placing greater demands on the functionality of nursing beds. Currently, most nursing beds on the market offer basic functions such as sitting up and turning over, but lack toileting and bathing functions. Even those that do often require complex movement mechanisms and control structures to achieve these functions. Furthermore, most current nursing beds do not consider the actual physical comfort of patients; rigid bed boards hinder blood circulation and prevent patients from maintaining a single posture for extended periods.

[0003] The existing nursing beds generally use a rigid board to support part of the patient's body to complete the turning and sitting up movements. This compresses the blood flow in the back or the side under pressure, making it difficult for the patient to circulate. It is not comfortable for the patient to maintain this position for a long time.

[0004] Furthermore, most traditional bed bathing methods currently on the market involve transferring the patient to an external inflatable bathtub for rinsing. This method is not only time-consuming and laborious but also neglects the patient's physiological privacy. Therefore, a more functional and practically feasible nursing bed needs to be designed. Summary of the Invention

[0005] This invention provides a nursing bed and its method of use to solve the technical problems of redundant functional mechanisms, poor user comfort, and lack of necessary nursing functions in the prior art.

[0006] This invention provides a nursing bed, comprising: a bed frame and a bed board;

[0009] The bed board includes: three interdigitated bed board assemblies connected sequentially from the headboard to the footboard, and connecting assemblies;

[0010] The interdigitated bed board assembly includes: two comb-shaped bed boards and a multi-link support;

[0011] The comb-shaped bed plate includes: two side strips, a first connecting shaft, a second connecting shaft, a first comb tooth plate, a second comb tooth plate, and a rotating motor;

[0012] Two side strips are respectively set on both sides of the bed, and one end of the side strip in the interdigitated bed board assembly near the head and foot of the bed is connected to the top of the telescopic rod of the adjacent telescopic assembly;

[0013] The connecting component connects one end of the side strip in the adjacent interdigitated bed board assembly. The two adjacent interdigitated bed board assemblies can be folded up and the folding angle can be fixed through the connecting component.

[0014] The first connecting shaft is installed inside the edge strip along the length of the edge strip, and the rotating motor drives the first connecting shaft to rotate inside the edge strip;

[0015] One end of the first comb plate is fixedly sleeved on the first connecting shaft, which can drive the first comb plate to rotate circumferentially along the first connecting shaft. The other end of the first comb plate is sleeved on the second connecting shaft. One end of the second comb plate is fixedly sleeved on the second connecting shaft and can rotate circumferentially along the second connecting shaft. Several first comb plates are evenly distributed on the first connecting shaft, and several second comb plates are evenly distributed on the second connecting shaft, forming a comb shape. The second comb plates between the two comb-shaped bed plates intersect to form a forked finger shape.

[0016] A multi-link support is provided at each end of the comb-shaped bed plate. The base of the multi-link support is fixed to the first comb plate, and the support end of the multi-link support is fixed to the second comb plate. The multi-link support supports the second comb plate to rotate circumferentially along the second connecting shaft.

[0017] Furthermore, the second comb plate of the interdigitated bed board assembly located in the middle of the bed board is divided into two sections, which are connected by a connector. The suspended end of the second comb plate can be vertically folded through the connector.

[0018] Furthermore, the multi-link support includes: a base, a connecting block, a support block, a first link, a second link, a third link, and a support link;

[0019] The base includes: a base shell and a motor;

[0020] The base shell is fixed to the first comb plate; the support block is fixed to the second comb plate; two first connecting rods are arranged in parallel, one end of the first connecting rod is connected to the base shell by a shaft, and the other end of the first connecting rod is connected to the connecting block by a shaft; one end of the second connecting rod is coaxially connected to the first connecting rod near the second comb plate on the connecting block, and the other end of the second connecting rod is connected to one end of the third connecting rod by a shaft, and the other end of the third connecting rod is connected to the support block by a shaft; one end of the support connecting rod is coaxially connected to the first connecting rod near the second comb plate on the connecting block, and the other end of the support connecting rod is coaxially connected to the third connecting rod on the support block; the motor is installed inside the base shell, and the motor output shaft is driven by the shaft of the first connecting rod on the base shell.

[0021] Furthermore, the support assembly includes: a telescopic support rod and a support connecting rod; the telescopic support rod is disposed at the four corners of the bottom frame; the top end of the telescopic support rod is connected to one end of the support connecting rod through a connector, and the other end of the support connecting rod is connected to a crossbar; the support connecting rod can rotate along the length of the bed.

[0022] Furthermore, the connection assembly includes a motor and a connector; the motor drives the connector to rotate.

[0023] Furthermore, the connector is a self-locking rotating shaft with a rotation angle.

[0024] Furthermore, the length of the second comb plate is longer than the length of the first comb plate.

[0025] Furthermore, a groove is provided on the inner wall of the long side of the bottom frame along the length of the bottom frame, and a rough-surfaced slide rail is provided in the groove.

[0026] The present invention also provides a method of using a nursing bed, comprising:

[0027] When you need to sit up:

[0028] Raise the height of the two support components at the head of the bed and lower the height of the two support components at the foot of the bed; adjust the connecting components so that the interdigitated bed board assembly at the head of the bed folds upward to the required angle and the interdigitated bed board assembly at the foot of the bed folds downward to the required angle, while keeping the interdigitated bed board assembly in the middle of the bed in a horizontal state.

[0029] When you need to use the restroom:

[0030] First, sit up. Then, fold the second comb plate of the interdigitated bed board assembly in the middle of the bed, which covers the area of ​​the buttocks, downward through the connector to form a hollow area. Finally, place the toilet under the hollow area.

[0031] When you need to take a bath:

[0032] Place the bathtub under the bed board, drive the motor to rotate the first comb plate downwards, push the second comb plate upwards through the multi-link support, control the telescopic component to retract inwards, form the bed board into a "U" shape, and lower the bed board into the bathtub through the support component;

[0033] When you need to turn to the side:

[0034] The second comb plate on one side is pushed upward to the desired angle by the multi-link support;

[0035] When the bed board width needs to be adjusted:

[0036] Control the telescopic component to retract inward to the required width.

[0037] The beneficial effects of this invention are:

[0038] 1. The bed of the present invention utilizes the changes in the shape of the comb-shaped bed board and the bed body supporting components to provide a more functional nursing bed, including sitting up, turning over, toileting, and bathing functions, which solves the problem that the current nursing beds have relatively basic functions and are difficult to cover other needs of patients;

[0039] 2. This invention achieves posture adjustment of the comb-shaped bed board by setting two sets of control motors to control the rotation direction and using multi-link support components for transmission. It can also control the posture adjustment rate and provide a more comfortable adjustment process.

[0040] 3. The multi-link support adopts a combination of multiple links and cranks to achieve a larger flipping angle. The multi-link support realizes the graded control of the comb-shaped bed board. The multi-link support is set outside the bed board, which can not only meet the basic bed board control requirements, but also solves the problem of difficult bed maintenance caused by the current internal control mechanism of the bed board of nursing beds.

[0041] 4. The comb-shaped bed board formed by the cross combination of comb plates has gaps, which solves the problem of poor blood circulation on the pressure side of the user when using rigid boards in current nursing beds; at the same time, the comb-shaped bed board can also be retracted inward, making it easy to adjust the bed width and adapt the bed to more usage environments;

[0042] 5. In realizing the functions of defecation and bathing, the bottom frame of this invention is equipped with a rough-surfaced slide rail. After adjusting the height of the bed, the caregiver can use the rough-surfaced slide rail to push in the bathtub or defecation device, which solves the problem of odor retention caused by the integration of the bed board and defecation device, and also reduces the complexity of the bed structure.
