Description

Technical Field

[0001] This utility model relates to the field of assisted turning technology, specifically an assisted turning device for patients with external fixation of pelvic fractures. Background Technology

[0002] The pelvis is a basin-shaped skeleton connecting the spine and lower limbs. It is a complete bony ring formed by the sacrum, coccyx, and the two hip bones at the back. The pelvis not only transfers body weight to the lower limbs and serves as the basis for the free lower limbs' movement, but also supports and protects the abdominal and pelvic organs. Because the center of the fracture site is close to internal organs, external fixators are often used to fix the pelvic fracture site. To prevent displacement of the fracture site, patients need to maintain a supine position for a long period of time.

[0003] In the care of patients with pelvic fractures, in order to prevent pressure sores from developing due to prolonged lying down, it is necessary to turn the patient over regularly. Since the fractured pelvis is fixed with steel pins, the patient cannot move on their own and needs the help of family members or medical staff to turn over, which makes the patient's turning over quite troublesome.

[0004] However, most existing assisted turning devices tilt the entire bed board, leaving the patient's buttocks still in contact with the bed board and bedding. This fails to provide adequate ventilation for the buttocks and still increases the risk of pressure sores. Therefore, those skilled in the art have provided an assisted turning device for patients with external fixation for pelvic fractures to address the problems mentioned in the background section. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an auxiliary turning device for patients with external fixation of pelvic fractures. This addresses the issue that most existing auxiliary turning devices tilt the entire bed board, which leaves the patient's buttocks still in contact with the bed board and bedding, failing to provide ventilation and still easily causing pressure sores.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary turning device for patients with external fixation of pelvic fractures, including a bed frame, a perforated bed board installed on the bed frame, a turbulence fan installed on the perforated bed board, an inclined plate assembly arranged inside the perforated bed board, a limiting hole longitudinally opened in the middle of the perforated bed board, a rotating shaft inserted into the limiting hole, an inclined plate assembly installed on the rotating shaft, and a motor installed on the outer wall of the bed frame.

[0009] Preferably, the inclined plate group is arranged in a staggered manner within the gaps of the hollow bed board.

[0010] Preferably, the motor is connected to the rotating shaft, which is rotatably engaged with the perforated bed board through a limiting hole. The rotating shaft is driven by the motor to rotate, and the rotation of the rotating shaft causes the tilting plate assembly to flip, so that one side of the tilting plate assembly tilts up, thereby assisting the patient in turning over.

[0011] Preferably, the turbulence fans are arranged in two rows longitudinally, with nine turbulence fans in each row. The two rows of turbulence fans are arranged on both sides of the patient's body, covering most of the patient's body. When the tilting plate group is tilted, the turbulence fans under the tilting plate group on the side that is tilted and raised are activated, thereby turbulenting the air on the side where the patient is turning over, increasing the ventilation effect through the bedding, and thus reducing the occurrence of pressure sores.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an auxiliary turning device for patients with pelvic fractures undergoing external fixation, which has the following beneficial effects:

[0014] This practical assisted turning device for patients with internal pelvic fractures and external fixation consists of a bed frame, a perforated bed board, and an inclined plate assembly. Two sets of turbulence fans are longitudinally installed on the perforated bed board, with multiple fans in each set distributed at various positions on the patient's body. When assisted turning is needed, a motor drives a rotating shaft to rotate, which in turn causes the inclined plate assembly to tilt and lift one side, thus assisting in turning the patient. When the inclined plate assembly tilts, the turbulence fan below the relatively raised side of the inclined plate assembly activates, thereby turbulenting the air on the side the patient is turning, increasing ventilation through the blankets, and reducing the likelihood of pressure sores.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: an auxiliary turning device for patients with pelvic fractures undergoing external fixation. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The bed frame includes a bed frame 1, a perforated bed board 2 installed on the bed frame 1, a turbulence fan 3 installed on the perforated bed board 2, an inclined plate assembly 5 inside the perforated bed board 2, a limiting hole 4 longitudinally opened in the middle of the perforated bed board 2, a rotating shaft 6 inserted into the limiting hole 4, an inclined plate assembly 5 installed on the rotating shaft 6, and a motor 7 installed on the outer wall of the bed frame 1.

[0021] Please see Figure 1 , Figure 2 , Figure 3 The inclined plate assembly 5 is set in the gaps of the hollow bed board 2 in an alternating arrangement. The motor 7 is connected to the rotating shaft 6 for driving. The rotating shaft 6 is rotated and engaged with the hollow bed board 2 through the limiting hole 4. The rotating shaft 6 is driven by the motor 7 to rotate. The rotation of the rotating shaft 6 causes the inclined plate assembly 5 to flip, so that one side of the inclined plate assembly 5 tilts up, thereby assisting the patient to turn over. The turbulence fans 3 are arranged in two rows longitudinally, with nine turbulence fans in each row. The two rows of turbulence fans 3 are set on both sides of the patient's body, covering most of the patient's body. When the inclined plate assembly 5 tilts, the turbulence fans 3 under the inclined plate assembly 5 on the relatively tilted and raised side are activated, thereby turbulenting the air on the side where the patient is turning over, increasing the ventilation effect through the bedding, thereby reducing the occurrence of pressure sores.

[0022] This practical auxiliary turning device for patients with external fixation of internal pelvic fractures consists of a bed frame 1, a hollow bed board 2, and an inclined plate assembly 5. Several gaps are opened on the hollow bed board 2, and the inclined plate assembly 5 is installed in the gaps. The hollow bed board 2 is fixedly installed to the bed frame 1. A limiting hole 4 is opened longitudinally in the middle of the hollow bed board 2, and a rotating shaft 6 passes through the limiting hole 4. The rotating shaft 6 is fixedly connected to the inclined plate assembly 5, and a motor 7 is driven to one end of the rotating shaft 6. The motor 7 is fixedly installed to the bed frame 1.

[0023] Two sets of turbulence fans 3 are installed longitudinally on the hollow bed board 2. Each set of turbulence fans 3 has multiple fans, and each set of turbulence fans 3 is distributed in multiple positions on the patient's body. When it is necessary to assist the patient in turning over, the motor 7 drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 causes the tilting plate group 5 to flip, so that one side of the tilting plate group 5 tilts up, thereby assisting the patient in turning over. When the tilting plate group 5 tilts, the turbulence fan 3 under the tilting plate group 5 on the relatively tilted and raised side is activated, thereby turbulenting the air on the side where the patient is turning over, increasing the ventilation effect through the bedding, thereby reducing the occurrence of pressure sores in the patient.
