Description

Technical Field

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

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

[0003] At present, existing position-maintaining beds are usually equipped with various position pads, such as surgical position pads. The design and materials of these pads are to prevent patients from suffering from skin injuries such as pressure sores and bedsores due to maintaining the same position for a long time, while also providing patients with a certain sense of comfort. These position pads have different shapes and specifications, such as a circular head ring for supporting and protecting the head, an upper limb concave position pad for protecting the elbows and maintaining the position of the hands, a shoulder pad for supporting the shoulders, a semicircular pad for supporting and protecting the knee joints, and a heel pad for protecting the heels. However, each time the position needs to be maintained, sometimes different position pads need to be used due to different surgical sites and different postoperative recovery. The position pads need to be replaced each time. At the same time, medical staff are required to assist the patient in adjusting the position each time, which is inconvenient to operate and inefficient. Summary of the invention

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

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

[0033] like Figure 2 and Figure 3As shown, the adjustment mechanism includes a driving motor 51, a driving gear 52, a transmission gear 53 and a protective shell 54. The driving motor 51 is installed in the middle of the front and rear sides of the connecting seat 2, and the protective shell 54 is installed on the front and rear sides of the connecting seat 2. The output shaft of the driving motor 51 penetrates into the protective shell 54 and is rotatably connected to the protective shell 54. The connecting shaft of the leaning plate 4 also penetrates into the protective shell 54 and is rotatably connected to the protective shell 54. The driving gear 52 is connected to the output shaft of the driving motor 51, and the transmission gear 53 is connected to the connecting shaft of the leaning plate 4. The driving gear 52 is meshed 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 shell 54, and the driving gear 52 and the transmission gear 53 can be protected by the protective shell 54.

[0034] like Figure 4-Figure 6 As shown, 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 push rod 66 and a push block 67. The front and rear sides of the top of the leaning plate 4 are rotatably connected to the large support plate 61, and the small support plate 62 is rotatably connected to the large support plate 61. The right side of the front large support plate 61 and the left side of the rear large support plate 61 are both slidably connected to the connecting rack 63. The lower rear part of the right connecting rack 63 and the lower front part of the left connecting rack 63 are both inclined. The transmission shaft of the small support plate 62 is connected to the connecting gear 64, and the two connecting gears 64 are respectively Meshing with the two connecting racks 63, two lifting cylinders 65 are provided on the left and right sides of the bottom of the leaning plate 4, and the two lifting cylinders 65 are arranged front and back. A pushing rod 66 is connected to the telescopic rod of the lifting cylinder 65, and the pushing rod 66 is slidably connected to the leaning plate 4. The pushing rod 66 moves upward to push the large supporting plate 61 to swing upward. The pushing rod 66 at the rear right side and the pushing rod 66 at the front left side are both connected with a pushing block 67, and the pushing block 67 is located below the inclined surface of the connecting rack 63, so that when the pushing block 67 moves upward, it can squeeze the connecting rack 63 to move through the inclined surface of the connecting rack 63.

[0035] like Figure 7 and Figure 8As shown, the leg supporting mechanism includes a connecting plate 71, a main swinging plate 72, a slave swinging plate 73, a reduction motor 74 and a connecting sleeve 75. The connecting plate 71 is connected to the left side of the top of the sitting plate 3. The reduction motor 74 is installed on the front and rear sides of the right side of the connecting plate 71. The output shaft of the reduction motor 74 is connected to the connecting sleeve 75. The main swinging plate 72 is rotatably connected to the connecting sleeve 75. The right side of the main swinging plate 72 is rotatably connected to the slave swinging plate 73. The upward swinging of the main swinging plate 72 will drive the left side of the slave swinging plate 73 to swing upward as well, so that the connection between the main swinging plate 72 and the slave swinging plate 73 moves upward, so as to bend the legs along the popliteal fossa, so that the patient can change the leg placement mode to make the patient more comfortable.

[0036] When a position-maintaining bed is needed, the present holding bed can be used. During use, the patient can lie on the bed body. After lying down, the patient's position can be adjusted according to actual needs. For example, 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, the transmission gear 53 can drive the leaning board 4 to rotate, so that the leaning board 4 can stand sideways to allow the patient to maintain a sitting position. If the patient needs to maintain a sideways position, the driving motor 51 can be controlled to drive the driving gear 52 to rotate. When the driving gear 52 rotates, the transmission gear 53 can drive the leaning board 4 to rotate, so that the leaning board 4 can stand sideways to allow the patient to maintain a sitting position. The patient lies sideways according to the desired side-standing direction. After lying sideways, the lifting cylinders 65 on the front and rear sides are controlled to rise and fall according to which side the patient lies closer to. For example, if the patient lies sideways and approaches the front side of the bed, the telescopic rod of the lifting cylinder 65 on the rear side is controlled to move upward. When the telescopic rod of the lifting cylinder 65 on the rear side 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, so that the rear large support plate 61 stands up. When the rear pushing rod 66 moves upward, it can also drive the pushing block 67 on the right side to move upward. When the right push 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 small supporting plate 62 on the front side to stand up. Through the cooperation of the large supporting plate 61 and the small supporting plate 62, the patient standing sideways can be supported to keep the patient in a sideways posture. On the contrary, if the patient lies on his side and approaches the back of the bed, the telescopic rod of the lifting cylinder 65 on the front side is controlled It can be stretched, and during use, if the patient's legs need 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 slave swing plate 73 to rotate, so that the main swing plate 72 and the slave swing plate 73 move up along their connection to support the bent legs. In this way, the device can be used to maintain the patient's posture, and can support a variety of postures according to actual needs, so as to facilitate the use of patients and have a wider range of applications.

[0037] like Fig. 9 and Fig.10 As shown, a support mechanism is also included, which includes a support curtain 81, an electric push rod 82 and a connecting rod 83. The electric push rods 82 are installed on the left and right sides of the two small support plates 62. A connecting rod 83 is connected between the telescopic rods of the two electric push rods 82 in the small support plate 62, and 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 plate 62, the support curtain 81 is pressed.

[0038] After the patient lies down, the whole body lies on the support curtain 81. Then when the patient stands on his side, the support curtain 81 can support the patient's body. Then the electric push rod 82 can be controlled to extend the telescopic rod to drive 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 to prevent the patient from being pressed on the large support plate 61 for a long time and causing numbness of the body.

[0039] like Figure 11-13 As shown, it also includes a leg frame mechanism, which includes a supporting seat 91, a connecting block 92, a locking frame 93 and a locking block 94. The connecting block 92 is slidably connected to the top of the swing plate 73, and the 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 ninety degrees to prevent the supporting seat 91 from rotating excessively. This is a prior art and will not be elaborated in detail. A locking frame 93 is installed on the top of the swing plate 73, and 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 propping up the connecting block 92.

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

[0041] When the patient is lying on his side, he can first pull the large support plate 61 and the small support plate 62 on one side to rotate ninety degrees, so that the large support plate 61 and the small support plate 62 stand up to support the patient's side, and then pull the support seat 91 to rotate ninety degrees. After the rotation is completed, pull the locking block 94 to slide to the right so that the locking block 94 is disengaged from the locking frame 93. At this time, pull the support seat 91 to slide up and down to adjust the height of the support seat 91. After the adjustment is completed, pull the locking block 94 to snap into the locking frame 93, and then the patient's legs can be placed on the support seat 91, so that the legs can be placed on the support seat 91 when lying on the side, and the legs are supported by the support seat 91.

[0042] like Fig.15 As shown, a transmission rod 11 is also included. The transmission rod 11 is inserted between the large support plate 61 and the main swing plate 72, so that the large support plate 61 can drive the main swing plate 72 to swing together when it swings. There is no need to pull the large support plate 61 and the main swing plate 72 to swing separately, which is more convenient to operate.

[0043] When lying on the device, the head can be rested on the arc-shaped support plate 104, and then the connecting frame 102 can be raised and lowered by extending the telescopic rod of the push cylinder 103, thereby controlling the height of the arc-shaped support plate 104 to adapt to patients of different body shapes. In this way, the patient's head can be supported.

[0044] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
