DETAILED DESCRIPTION

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0033] A protective restraint bed for agitated patients after surgery, such as Figure 1-Figure 5 As shown, it includes a base frame 1, a scissor-type lifting frame 2, a bed frame 3, a leaning board 4, a bed board 1 5, a bed board 2 6, an arc-shaped restraining plate 71 and a driving mechanism. The scissor-type lifting frame 2 is installed on the top of the base frame 1, and the bed frame 3 is installed on the top of the scissor-type lifting frame 2. The bed frame 3 is installed with leaning boards 4 on both sides. The bed board 1 5 and the bed board 2 6 are each provided with two and are respectively placed on the left and right sides of the bed frame 3. The bed board 2 6 is located on the inner side of the bed board 1 5. The two bed boards 2 6 are hingedly connected to each other and the connection is connected to the middle of the bed frame 3. The bed board 2 6 is fixedly connected to the bed board 1 5 close to it. The front and rear sides of the two bed boards 1 5 are slidably connected with arc-shaped restraining plates 71. The arc-shaped restraining plates 71 can be rotated to the top of the bed board 1 5 and cover the hands and feet of the patient to restrain the patient. The bed board 1 5 is provided with a driving mechanism for driving the arc-shaped restraining plates 71 to rotate.

[0034] like Figure 1 and Figure 2 As shown, a cushion 41 is also included. The two sides of the two leaning boards 4 that are close to each other are connected with the cushion 41, so that the patient can be supported by the cushion 41 when sitting up and leaning, making the patient more comfortable when leaning.

[0035] like Figure 3-Figure 5 As shown, the driving mechanism includes a driving gear 72 and a driving motor 73. The driving motors 73 are installed on the front and rear sides of the two bed boards 5. The driving gear 72 is connected to the output shaft of the driving motor 73. The outer arc surface of the arc-shaped constraint plate 71 is evenly spaced with teeth, and the driving gear 72 is meshed with the teeth, so that the driving motor 73 can drive the arc-shaped constraint plate 71 to rotate through the driving gear 72 and the teeth when in operation.

[0036] When a restless patient after surgery needs to use a hospital bed, the present hospital bed can be used. During use, the patient can lie on the bed board 1 5 and the bed board 2 6 on both sides, and then the drive motor 73 can be controlled to operate to drive the drive gear 72 to rotate. When the drive gear 72 rotates, it can drive the arc-shaped constraint plate 71 to rotate through the tooth groove. After the arc-shaped constraint plate 71 rotates, it can cover the patient's wrists and ankles, thereby restraining the patient and preventing the patient from being restless. When restraining, it is only necessary to control the operation of the drive motor 73, which is more convenient to operate. When the patient needs to get into bed, the scissor-type lifting frame 2 can be controlled to descend first, so that the bed frame 3 moves down, and then the patient can lie on the bed more conveniently. After lying down, the scissor-type lifting frame 2 can be controlled to move up to move the bed frame 3 up. In this way, it can make it more convenient for the patient to get in and out of bed. In this way, the present hospital bed can be used, and when in use, the patient can be restrained by the arc-shaped constraint plate 71.

[0037] like Figure 6 and Figure 7 As shown, it also includes an elastic fixing mechanism, which includes an airbag 81, an air pump 82 and an air pipe 83. The airbag 81 is installed on the inner arc surface of the arc-shaped constraint plate 71, and the air pump 82 is installed on the front and rear sides of the bottom of the two bed boards 5. The air pump 82 and the airbag 81 close to it are connected by an air pipe 83. The air pipe 83 is a telescopic hose. Controlling the operation of the air pump 82 can inject air into the airbag 81 through the air pipe 83, so that the airbag 81 expands.

[0038] When the arc-shaped restraint plate 71 restrains the patient, the air pump 82 can be controlled to operate and inject air into the airbag 81 through the air supply pipe 83, so that the airbag 81 expands. After the airbag 81 expands, it can resist the patient's wrist and ankle to restrain the patient. The restraint by the expansion of the airbag 81 can be performed on patients with different wrist and ankle thicknesses, and the application range is wider. The airbag 81 has a certain elasticity, which can also make the patient more comfortable.

[0039] like Figure 8-Figure 12 As shown, a lifting mechanism is also included, which includes a connecting frame 91, a swing frame 92, a guide rail 93, an electric push rod 94 and a sliding shaft 95. The connecting frame 91 is connected to the left side of the bottom of the right bed board 6, and the bottom of the connecting frame 91 is hingedly connected to the swing frame 92. The right side of the bed frame 3 is connected to the guide rail 93, and the top of the swing frame 92 is connected to the sliding shaft 95. The sliding shaft 95 is slidably connected to the guide rail 93, and the movement of the sliding shaft 95 can be guided by the guide rail 93. An electric push rod 94 is installed on the right side of the bed frame 3, and the telescopic rod of the electric push rod 94 is connected to the sliding shaft 95.

[0040] like Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, a supporting mechanism is also included, and the supporting mechanism includes a rotating rod 101 and a swing rod 102. The right side of the bed frame 3 is rotatably connected to the rotating rod 101, and the front and rear sides of the rotating rod 101 are connected to the swing rod 102. The end of the swing rod 102 is rotatably connected to the bottom of the right bed board 5. After the bed board 5 is lifted, the swing rod 102 will be driven to swing, and the swing rod 102 can assist in supporting the bed board 5.

[0041] Initially, the telescopic rod of the cylinder is in an extended state. When the patient needs to sit, the electric push rod 94 can be controlled to retract the telescopic rod to drive the sliding shaft 95 to move to the right. When moving, the sliding shaft 95 can pull the swing frame 92 to move to the right. When moving to the right, the swing frame 92 can pull the connecting frame 91 to swing. When swinging, the connecting frame 91 can drive the right-side bed board 1 5 and bed board 2 6 to swing upward. When swinging, the right-side bed board 1 5 and bed board 2 6 can drive the swing rod 102 to move upward, and then the swing rod 102 and the rotating rod 101 can be used to resist the bottom of the bed board 1 5, thereby supporting the bed board 1 5, thereby lifting the right-side bed board 1 5 and bed board 2 6, so as to support the patient's sitting, making the patient more comfortable when sitting.

[0042] like Fig.13 As shown, a protective mechanism is also included, which includes a side panel 111, a support rod 112 and a protective frame 113. The lower parts of the front and rear sides of the two leaning boards 4 are connected to the side panels 111, and the upper and lower sides of the side panels 111 are rotatably connected to the support rods 112. Two protective frames 113 are provided, and the two protective frames 113 are rotatably connected between the four support rods 112 on the front side and the four support rods 112 on the rear side, respectively. The protective frames 113 can shield and protect the patients on the bed board 1 5 and the bed board 2 6.

[0043] like Fig.14 and Fig.15 As shown, a locking mechanism is also included, which includes a hook 121, a shaft 122 and an elastic member 123. The lower support rod 112 is connected with the shaft 122. The side plate 111 is rotatably connected with the hook 121. A groove is provided on the hook 121, and the groove can hook the shaft 122 for locking the shaft 122. The groove is located at the moving track of the shaft 122. An elastic member 123 is connected between the hook 121 and the side plate 111, and the elastic member 123 is a torsion spring.

[0044] After the patient lies on the bed, he can pull the protective frame 113 to move up. When the protective frame 113 moves up, it can drive the support rod 112 to move up. When the support rod 112 moves up, it can drive the clamping shaft 122 to move up. When the clamping shaft 122 moves up, it can contact the groove position of the hook 121. Then, the clamping shaft 122 continues to move up, which will push the hook 121 to swing upward, and the elastic member 123 will be deformed until the clamping shaft 122 is aligned with the groove. At this time, the clamping shaft 122 will be stuck in the groove. At this time, the two protective frames 113 are just located at the patient's side. The protective frame 113 can be loosened on the front and rear sides of the bed. Under the action of the elastic member 123, the hook 121 is reset to drive the groove to clamp the clamping shaft 122, and the clamping shaft 122 is fixed, thereby assisting in fixing the protective frame 113 to provide shielding and protection for the patient. When the protective frame 113 needs to be removed, the hook 121 can be pulled upward to disengage the groove from the clamping shaft 122. Under the action of gravity, the protective frame 113 and the support rod 112 swing downward to reset, thereby completing the work of removing the protective frame 113.

[0045] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
