DETAILED DESCRIPTION
[0020] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.
[0021] Embodiment: A posture fixation device for orthopedic postoperative care, such as Figure 1-Figure 5 As shown, it includes a fixed plate 1, a rotating plate 2, a clamping assembly and a lifting assembly. The right end of the fixed plate 1 is rotatably connected to the rotating plate 2. The rotating plate 2 is provided with a clamping assembly for clamping the patient's legs. The fixed plate 1 is provided with a lifting assembly for lifting and flipping the rotating plate 2 upward.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly includes a slider 31, a clamping plate 32, a servo motor 321, a screw 33, a dual-axis motor 34, a signal receiver 35 and a remote control 36. Grooves are symmetrically provided on the right side of the rotating plate 2. The sliders 31 are slidably connected to the two grooves on the rotating plate 2. The clamping plates 32 are rotatably connected to the two sliders 31. The servo motors 321 are embedded in the right parts of the two sliders 31. The output shaft ends of the two servo motors 321 are fixedly connected to the right ends of the adjacent clamping plates 32. The screw 33 is symmetrically embedded and rotatably connected to the part between the two grooves on the rotating plate 2. The two screw rods 33 respectively penetrate the two sliders 31 and cooperate with them through threads. The threads on the two screw rods 33 are in opposite directions. When the dual-axis motor 34 drives the two screw rods 33 to rotate, the two screw rods 33 can respectively drive the two sliders 31 to move closer to or away from each other through thread cooperation. The part located between the two grooves on the rotating plate 2 is also embedded and fixedly connected with the dual-axis motor 34. The ends of the two output shafts of the dual-axis motor 34 are respectively fixedly connected with the ends of the adjacent screw rods 33. A signal receiver 35 is installed on the top right side of the fixed plate 1, and a remote control 36 is placed on the top right side of the rotating plate 2 through magnetic fixation. Figure 1 and Figure 2As shown, the lifting assembly includes an airbag 41, an inflator 42 and an inflation tube 43. The airbag 41 is fixedly connected to the middle of the top of the fixed plate 1, the inflator 42 is installed on the left side of the top of the fixed plate 1, and the inflation tube 43 is connected between the inflator 42 and the airbag 41. The signal receiver 35 can receive signals from the remote control 36 and control the opening and closing of the servo motor 321, the dual-axis motor 34 and the inflator 42 according to these signals.
[0023] When the present embodiment is used, the patient is firstly laid flat on the bed, and then the fixing plate 1 is placed on the bed. Initially, the two splints 32 are both in a horizontal state. The fixing plate 1 is moved so that the right end of the rotating plate 2 is close to the patient's buttocks. At this time, the rotating plate 2 is located below the patient's injured leg. The two servo motors 321 are then started by the remote control 36. The two servo motors 321 respectively drive the two splints 32 to flip upward 90 degrees. The dual-axis motor 34 is then started by the remote control 36. The dual-axis motor 34 drives the two screw rods 33 to rotate, thereby driving the two sliders 31 to slide in a direction close to each other, thereby causing the two splints 32 to gradually clamp the patient's thighs until the patient feels a more comfortable clamping force. The dual-axis motor 34 is turned off, and the inflator 42 is started through the remote control 36. The inflator 42 inflates the airbag 41 through the inflation tube 43, thereby lifting the rotating plate 2 upward and flipping it. After the rotating plate 2 is flipped upward to a suitable angle, the inflator 42 is turned off. At this time, the rotating plate 2 lifts the patient's injured leg upward, which can promote blood return to the patient's leg, and help to reduce swelling and heal the fracture after surgery. When the patient wants to get out of bed and move around, the remote control 36 can be used to reset the rotating plate 2 downward, and then the two splints 32 are opened and restored to a horizontal state. The patient only needs to move his legs horizontally to detach from the rotating plate 2. There is no need to untie the legs, and no assistance from others is required. In this way, the patient's comfort is improved.
[0024] like Figure 1 and Figure 2 As shown, it also includes a fixing seat 51 and a fastening screw 52 . The fixing seat 51 is fixedly connected to the left side of the top of the fixing plate 1 , and the fastening screw 52 is threadedly connected to the fixing seat 51 .
[0025] By providing a fixing seat 51 and a fastening bolt, the fastening bolt is fixedly connected to the rotating plate 2 through a thread, so as to limit the rotation of the rotating plate 2, and facilitate the movement and transfer of the device.
[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a baffle 62 is also included. A slot 61 is symmetrically provided in the middle of the two grooves on the rotating plate 2. The baffle 62 is fixedly connected to the side walls of the two sliders 31 that are close to each other.
[0027] By providing the baffle 62 , the groove formed on the rotating plate 2 can be shielded to prevent debris from falling into the groove, thereby affecting the normal sliding of the slider 31 .
[0028] like Figure 5 As shown, a rubber pad 7 is also included, and a plurality of rubber pads 7 are fixedly connected to the bottom of the fixing plate 1 in an interval manner.
[0029] By providing the rubber pad 7, the friction between the fixing plate 1 and the bed can be increased to prevent the fixing plate 1 from sliding during use.
[0030] 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 may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
