Description

Technical Field

[0001] The present invention belongs to the technical field of nursing beds and relates to a medical multi-functional body position maintaining bed. Background Art

[0002] During the operation or postoperative recovery of patients, a body position maintaining bed is usually required to maintain the patient's body position. A body position maintaining bed is a medical bed specially designed for operating rooms or rehabilitation environments, and its main function is to help the patient maintain a specific body position to ensure the smooth progress of the operation or treatment process.

[0003] Currently, existing body position maintaining beds are usually equipped with various body position pads, such as surgical body position pads. The design and material of these pads are to avoid skin injuries such as pressure sores and bedsores caused by the patient maintaining the same body position for a long time, and at the same time, they can also bring a certain degree of comfort to the patient. These body position pads have different shapes and specifications. For example, a circular head ring is used to support and protect the head, an upper limb concave body position pad is used to protect the elbows and maintain the hand position, a shoulder pad is used to support the shoulders, a semi-circular pad is used to support and protect the knees, and a heel pad is used to protect the heels, etc. However, each time when the body position needs to be maintained, sometimes due to different surgical sites and different postoperative recoveries, different body position pads are required, and the body position pads need to be replaced each time. At the same time, medical staff also need to assist the patient to adjust the body position each time, which is inconvenient to operate and has low efficiency. Summary of the Invention

Specific embodiments

[0031] Reference to an embodiment in this context means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] A medical multifunctional body position maintaining bed, as Figures 1 - 8 shown, includes a base 1, a connecting seat 2, a seat board 3, a leaning board 4, an adjusting mechanism, a side support mechanism and a leg supporting mechanism. The top of the base 1 is connected with the connecting seat 2. The right side of the top of the connecting seat 2 is connected with the seat board 3. The left side of the seat board 3 is rotatably connected with the leaning board 4. When a patient lies on the seat board 3 and the leaning board 4, the legs are placed on the seat board 3 and the back leans against the leaning board 4. An adjusting mechanism for adjusting the inclination angle of the leaning board 4 is provided on the connecting seat 2. A side support mechanism is provided on the leaning board 4. A leg supporting mechanism is provided on the seat board 3.

[0033] As Figure 2 and Figure 3As shown in the figure, the adjusting mechanism includes a driving motor 51, a driving gear 52, a transmission gear 53 and a protective housing 54. Driving motors 51 are installed in the middle of the front and rear sides of the connecting seat 2. Protective housings 54 are installed on both the front and rear sides of the connecting seat 2. The output shaft of the driving motor 51 penetrates into the protective housing 54 and is rotatably connected to the protective housing 54. The connecting shaft of the leaning plate 4 also penetrates into the protective housing 54 and is rotatably connected to the protective housing 54. A driving gear 52 is connected to the output shaft of the driving motor 51. A transmission gear 53 is connected to the connecting shaft of the leaning plate 4. The driving gear 52 meshes with the transmission gear 53, so that the operation of the driving motor 51 can drive the leaning plate 4 to rotate through the driving gear 52 and the transmission gear 53. The driving gear 52 and the transmission gear 53 are both located in the protective housing 54, and the protective housing 54 can protect the driving gear 52 and the transmission gear 53.

[0034] As Figures 4 - 6 shown in the figure, the side support mechanism includes a large support plate 61, a small support plate 62, a connecting rack 63, a connecting gear 64, a lifting cylinder 65, a pushing rod 66 and a pushing block 67. Large support plates 61 are rotatably connected to the front and rear sides of the top of the leaning plate 4. A small support plate 62 is rotatably connected to the large support plate 61. Connecting racks 63 are slidably connected to the right side of the front large support plate 61 and the left side of the rear large support plate 61. The lower parts of the rear side of the right connecting rack 63 and the front side of the left connecting rack 63 are both inclined. A connecting gear 64 is connected to the transmission shaft of the small support plate 62. The two connecting gears 64 are respectively meshed with the two connecting racks 63. Two lifting cylinders 65 are arranged on the left and right sides of the bottom of the leaning plate 4. The two lifting cylinders 65 are arranged front and rear. A pushing rod 66 is connected to the telescopic rod of the lifting cylinder 65. The pushing rod 66 is slidably connected to the leaning plate 4. When the pushing rod 66 moves upward, it can push the large support plate 61 to swing upward. Pushing blocks 67 are connected to the pushing rods 66 at the rear of the right side and the front of the left side. The pushing blocks 67 are located below the inclined surface of the connecting rack 63, so that when the pushing blocks 67 move upward, they can squeeze the connecting rack 63 to move through the inclined surface of the connecting rack 63.

[0035] As Figure 7 and Figure 8As shown, the leg support mechanism includes a connecting plate 71, a main swing plate 72, a secondary swing plate 73, a reduction motor 74, and a connecting sleeve 75. A connecting plate 71 is connected to the left side of the top of the seat plate 3. Reduction motors 74 are installed on both the front and rear sides of the right side inside the connecting plate 71. A connecting sleeve 75 is connected to the output shaft of the reduction motor 74. The main swing plate 72 is rotatably connected to the connecting sleeve 75. The secondary swing plate 73 is rotatably connected to the right side of the main swing plate 72. When the main swing plate 72 swings upward, it will drive the left side of the secondary swing plate 73 to swing upward as well, causing the connection point between the main swing plate 72 and the secondary swing plate 73 to move upward, so as to bend the leg along the popliteal fossa, enabling the patient to change the leg placement form and making the patient more comfortable.

[0036] When the body position maintaining bed needs to be used, this maintaining bed can be used. During the use process, the patient can lie on this bed body. After lying down, the patient's body position can be adjusted according to actual needs. If the patient needs to sit up, the driving motor 51 can be controlled to drive the driving gear 52 to rotate. When the driving gear 52 rotates, it drives the transmission gear 53 to rotate. When the transmission gear 53 rotates, it can drive the leaning plate 4 to rotate, so that the leaning plate 4 stands upright to keep the patient in a sitting body position. If the patient needs to maintain a side-lying body position, the patient can lie on the side according to the direction of the side-lying required. After lying on the side, the lifting cylinders 65 on the front and rear sides are controlled to lift according to which side is closer after lying on the side. For example, if the patient lies on the side close to the front side of the bed body, the telescopic rod of the rear lifting cylinder 65 is controlled to move upward. When the telescopic rod of the rear lifting cylinder 65 moves upward, it can drive the rear pushing rod 66 to move upward. When the rear pushing rod 66 moves upward, it can squeeze the rear large support plate 61 to swing upward, causing the rear large support plate 61 to stand upright. Moreover, when the rear pushing rod 66 moves upward, it can also drive the right pushing block 67 to move upward. When the right pushing block 67 moves upward, it will contact the right connecting rack 63, thereby squeezing the connecting rack 63 to move forward. When the connecting rack 63 moves forward, it will drive the connecting gear 64 to rotate. When the connecting gear 64 rotates, it can drive the front small support plate 62 to stand upright. Through the cooperation of the large support plate 61 and the small support plate 62, the side-lying patient can be supported to keep the patient in a side-lying posture. On the contrary, if the patient lies on the side close to the rear side of the bed body, the telescopic rod of the front lifting cylinder 65 is controlled to extend. During the use process, if the patient's leg needs to be bent, the reduction motor 74 can be controlled to drive the connecting sleeve 75 to rotate. When the connecting sleeve 75 rotates, it can drive the main swing plate 72 to rotate, thereby driving the secondary swing plate 73 to rotate, causing the main swing plate 72 and the secondary swing plate 73 to move upward along their connection point to support the bent leg. In this way, this device can be used to maintain the patient's body posture and can support various body postures according to actual needs, facilitating the patient's use and having a wider range of applications.

[0037] As Figure 9 andFigure 10 As shown, it further includes a support mechanism. The support mechanism includes a support curtain 81, an electric push rod 82, and a connecting rod 83. Electric push rods 82 are installed on the left and right sides inside both small support plates 62. A connecting rod 83 is connected between the telescopic rods of the two electric push rods 82 inside the small support plate 62. A support curtain 81 is connected between the two connecting rods 83. When the patient lies on the large support plate 61 and the small support plates 62, the support curtain 81 is pressed down.

[0038] After the patient lies down well, the whole body lies on the support curtain 81. Subsequently, when the patient stands sideways, the support curtain 81 can support the patient's body. Then, the telescopic rod of the electric push rod 82 can be controlled to extend, driving the connecting rod 83 to move downward. When the connecting rod 83 moves downward, it pulls the support curtain 81 to move, so that the support curtain 81 lifts the patient's body upward, preventing the patient from being oppressed on the large support plate 61 for a long time and causing the body to become numb.

[0039] As Figures 11 - 13 shown, it further includes a leg support mechanism. The leg support mechanism includes a supporting seat 91, a connecting block 92, a locking frame 93, and a locking block 94. A connecting block 92 is slidably connected to the top of the secondary swing plate 73. A supporting seat 91 is rotatably connected to the connecting block 92. A locking structure is provided on the connecting block 92, so that the supporting seat 91 will be stuck after rotating 90 degrees, preventing the supporting seat 91 from rotating excessively. This is prior art and will not be elaborated specifically. A locking frame 93 is installed on the top of the secondary swing plate 73. A locking block 94 is slidably connected to the connecting block 92. The locking block 94 can be stuck on the locking frame 93, thereby lifting the connecting block 92.

[0040] As Figure 14 shown, it further includes a headrest mechanism. The headrest mechanism includes a mounting frame 101, a connecting frame 102, a pushing air cylinder 103, and an arc-shaped supporting plate 104. A mounting frame 101 is connected to the left side of the leaning plate 4. A connecting frame 102 is slidably connected to the mounting frame 101. An arc-shaped supporting plate 104 is connected to the right side of the top of the connecting frame 102. A pushing air cylinder 103 is installed on the mounting frame 101. The telescopic rod of the pushing air cylinder 103 is connected to the connecting frame 102.

[0041] When the patient lies on the side, one side of the large support plate 61 and the small support plates 62 can be pulled to rotate 90 degrees first, so that the large support plate 61 and the small support plates 62 stand up to support the patient's side. Subsequently, the supporting seat 91 is pulled to rotate 90 degrees. After the rotation is completed, the locking block 94 is pulled to slide to the right, so that the locking block 94 is disengaged from the locking frame 93. At this time, the supporting seat 91 is pulled to slide up and down to adjust the height of the supporting seat 91. After the adjustment is completed, the locking block 94 is pulled to be inserted into the locking frame 93. Then, the patient's leg can be placed on the supporting seat 91, so that when lying on the side, the leg can be placed on the supporting seat 91, and the supporting seat 91 supports the leg.

[0042] As shown Figure 15 in the figure, a transmission rod 11 is further included. The transmission rod 11 is inserted between the large support plate 61 and the main swing plate 72, so that when the large support plate 61 swings, it will drive the main swing plate 72 to swing together, without the need to pull the large support plate 61 and the main swing plate 72 to swing separately, which is more convenient in operation.

[0043] When lying on this device alternately, the head can be rested on the arc-shaped supporting plate 104. Subsequently, the telescopic rod of the push cylinder 103 can be extended and retracted to drive the connecting frame 102 to rise and fall, thereby controlling the height of the arc-shaped supporting plate 104 to adapt to patients of different body types. In this way, the head of the patient can be supported.

[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
