Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and more particularly to a medical bed with a foldable dining table. Background Art

[0002] For patients who need hospitalization, in addition to injections and medications, they also need meals every day. However, the dining areas in most hospitals are far away from the wards, so the bedside dining table has become an indispensable auxiliary equipment for hospitalized patients to eat.

[0003] At present, some hospital beds do not have matching dining tables. When patients eat, they can only put their meals at the head of the bed, which makes it inconvenient for patients to eat and easily spills soup on the sheets, increasing the cost of cleaning. The beds equipped with dining tables are mainly divided into three categories. The first category is a mobile dining table, which is independent of the bed. Patients can place food on the table when eating, but this type of table takes up a lot of space in the ward, and patients are prone to pile up items other than food on the table, which affects both the operation of medical staff and the activities of patients, increasing the risk of patients falling in the ward; the second category is an independent table board, which is usually placed at the end of the bed and can be freely placed on the bed when eating. After the meal, it can be placed at the end of the bed; the third category is a folding dining table, which is integrated with the bed and is mostly designed at the end of the bed or next to the bed. The second and third categories of dining tables do not take up space in the ward, but patients can usually only eat on the bed, which easily leads to patients relying on the bed, which does not conform to the modern nursing concept of reducing patients' bed rest and increasing the time of activities outside the bed, and is also prone to increase the risk of aspiration due to poor posture during eating. Summary of the invention

[0004] The purpose of the present invention is to provide a medical bed with a foldable dining table, which solves the problem in the prior art that the dining table of the bed easily causes the patient to be dependent on the bed.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A medical bed with a foldable dining table comprises a bed body, a front bracket and two rear pillars are fixed to the bottom side of the bed body, a fixing frame is fixed to one end of the bed body near the end of the bed, a dining table board is arranged inside the fixing frame, one end of the dining table board is rotatably connected to the fixing frame, first slide grooves are provided on both sides of the dining table board, an expansion plate is slidably connected inside the first slide groove, a first spring is fixed between the expansion plate and the dining table board, a side of the expansion plate away from the first spring can be moved to the outside of the first slide groove and clamped with the fixing frame, and the expansion plate abuts against the fixing frame when not moved to the outside of the first slide groove.

[0007] By adopting the above technical solution, when an inpatient needs to eat, he needs to get out of bed and walk to the end of the bed, and then rotate the dining table board so that the dining table board is parallel to the ground. When the dining table board is parallel to the ground, the expansion plates on both sides of the dining table board are separated from the abutment of the fixed frame. At this time, the expansion plate is moved to the outside of the dining table board by the elastic force of the first spring and is stuck on the fixed frame, so that the dining table board can be maintained in a position parallel to the ground, preventing the dining table board from being reset due to gravity, and also expanding the area of ​​the dining table board; the dining table board is set at the end of the bed, so that when the patient needs to eat, he can only get out of bed and walk to the bed to use the dining table board to eat, which can reduce the dependence of inpatients on beds and is in line with modern nursing concepts.

[0008] The present invention is further configured as follows: a first rack is fixed to one end of the two expansion plates close to the first spring, the two first racks are centrally symmetrically arranged, the two first racks are slidably connected in the dining table board, a first gear is rotatably connected in the dining table board, and the first gear is meshed with the two first racks.

[0009] By adopting the above technical solution, when it is necessary to fold the dining table board again, an expansion plate can be pushed into the first slide groove at will, and the expansion plate pushes the first rack fixed to it to slide, and the first rack drives the first gear to rotate, and the first gear drives another first rack to slide, and then drives the other expansion plate into the corresponding first slide groove. When the two expansion plates enter the corresponding first slide grooves respectively, the expansion plates are no longer stuck in the fixed frame, and then the dining table board can be reset, making the operation of folding the dining table board easier.

[0010] The present invention is further configured as follows: a second sliding groove is provided on both expansion plates, a parallel plate is slidably connected in the second sliding groove, a second spring is fixed between the parallel plate and the expansion plate, a first inclined surface is provided at one end of the parallel plate close to the first spring, and a second inclined surface matching the first inclined surface is provided at the open end of the first sliding groove.

[0011] By adopting the above technical scheme, when the expansion plate has not slid out of the first slide groove, the parallel plate is resisted by the inner wall of the first slide groove and is completely located in the second slide groove. When the expansion plate slides out of the first slide groove due to the elastic force of the first spring, the parallel plate is disengaged from the resistance of the inner wall of the first slide groove and is lifted up by the elastic force of the second spring, so that the side of the parallel plate away from the spring and the side of the dining table board where the tableware is placed are located in the same plane, avoiding the situation where the expansion plate and the dining table board are located in different planes and causing the tableware to be unevenly placed; when the parallel plate is lifted to be on the same horizontal plane as the dining table board, the first inclined surface and the second inclined surface overlap with each other. Through such an arrangement, when the dining table board is folded, the first inclined surface of the parallel plate is pressed by the second inclined surface and can smoothly return to the second slide groove.

[0012] The present invention is further configured as follows: a locking bolt is threadedly connected to the fixing frame, and a limiting hole for inserting the locking bolt is opened on one side of the dining table board.

[0013] By adopting the above technical solution, when the patient is not using the dining table board, the locking bolt can be inserted into the limiting hole to limit the rotation of the dining table board.

[0014] The present invention is further configured as follows: a seat is provided on the bottom side of the bed body, and the seat is located between two rear pillars.

[0015] By adopting the above technical solution, when the patient uses the dining table, the chair under the bed can be directly pulled out to eat, which will not occupy too much space in the ward.

[0016] The present invention is further configured as follows: a mounting portion is fixed to the lower side of the bed body, a first rotating shaft is rotatably connected in the mounting portion, a second gear located in the mounting portion is keyed on the first rotating shaft, a second rack is meshed on the second gear, the second rack passes through the mounting portion and is slidably connected to the mounting portion, and an end of the second rack near the end of the bed is fixed to the seat; both ends of the first rotating shaft pass through the mounting portion, and both ends of the first rotating shaft are keyed to the first pulley; two symmetrical slide rails are provided on the side of the dining table board near the bed body, and a third rack is provided on the two slide rails, and the two third racks are inclined to the surface of the bed body, and one end of the third rack can slide and rotate on the slide rail, and the two third racks respectively pass through the rear pillars on the same side thereof, and the third rack is slidably connected to the rear pillars; the second rotating shaft is rotatably connected in the two rear pillars, one end of the second rotating shaft is keyed to the third gear located in the rear pillar, and the end of the second rotating shaft away from the third gear extends outside the rear pillar and is keyed to the second pulley, and the second pulley is connected to the first pulley by a belt.

[0017] By adopting the above technical solution, when the patient pulls out the chair under the bed, the chair drives the second rack to slide, the second rack drives the second gear to rotate, the second gear drives the first rotating shaft to rotate, the first rotating shaft drives the first pulley to rotate, the first pulley drives the second pulley to rotate through the belt, the second pulley drives the third gear to rotate through the second rotating shaft, the third gear drives the second rack to slide, and one end of the second rack located in the slide rail slides and rotates in the slide rail, thereby lifting the dining table board until the dining table board is parallel to the ground, and the expansion plate pops out to limit the dining table board to this position; through such an arrangement, when the patient pulls out the chair, the dining table board is lifted up by the transmission action, which on the one hand improves the dining efficiency and makes the operation of the device more convenient, and on the other hand standardizes the position of the seat, avoiding that the patient puts the dining chair randomly and reduces the available space in the ward; and the two second racks can also play a supporting role for the dining table board, share the pressure of the fixed frame on the expansion plate, and improve the service life of the dining table board.

[0018] The present invention is further configured as follows: the seat is a pneumatic lift chair, four pulleys are installed on the bottom side of the seat, and a handle is fixed on the side of the seat away from the head of the bed.

[0019] By adopting the above technical solution, it is convenient for patients to operate the chair better.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The dining table of the medical bed is set at the end of the bed. When the patient needs to eat, he can only get out of bed and walk to the bed to use the dining table to eat, which can reduce the dependence of hospitalized patients on the bed and conform to the modern nursing concept.

[0022] 2. The medical bed cooperates with the dining table board by setting an expansion plate. When the dining table board is rotated to be parallel to the ground, the expansion plate can pop out and engage with the fixing frame, limiting the dining table board to a position parallel to the ground. At the same time, the expansion plate can expand the area of ​​the dining table board after popping out, so that the usable area of ​​the dining table board is larger, which is convenient for patients to dine; and through the mutual cooperation of the first rack and the first gear, folding the expansion plate is more convenient.

[0023] 3. The medical bed is provided with a parallel plate. When the expansion plate pops out, the parallel plate also pops out from the expansion plate, so that the parallel plate and the dining table plate are located in the same plane, avoiding the situation where the expansion plate and the dining table plate are located in different planes and causing uneven placement of tableware; and through the mutual cooperation of the first inclined surface and the second inclined surface, it is more convenient to fold the parallel plate.

[0024] 4. The medical bed is provided with a seat and a second rack, a third rack and other transmission structures that cooperate with each other, so that when the patient pulls out the seat, the dining table board can be lifted up through the action of these transmission structures. On the one hand, it improves the dining efficiency and makes the operation of the device more convenient. On the other hand, it also standardizes the position of the seat to prevent patients from placing the dining chairs randomly and reducing the available space in the ward. The two second racks can also support the dining table board, share the pressure of the fixed frame on the expansion board, and increase the service life of the dining table board.
