Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to a medical auxiliary turning device. Background Art

[0002] The contents of this section merely provide background information related to the present application and may not constitute prior art.

[0003] In hospital nursing work, since some patients lie in a supine position for a long time, the bedridden parts of their bodies are prone to pressure sores, and being in the same position for a long time will also make patients feel uncomfortable. Therefore, it is often necessary to turn patients over. Patients who need help to turn over often have poor autonomy, which requires medical staff to expend a lot of effort to complete. However, the vast majority of medical staff in hospital nursing work are women, which brings certain inconveniences to medical staff.

[0004] The Chinese patent document with the authorization announcement number CN217566618U discloses a medical auxiliary turning device, including a pad body, a connecting belt, a movable pulley, and a force belt fixed at the first end. The first end of the connecting belt is connected to the first side of the pad body, the movable pulley is slidably connected to the second side of the pad body, the first side and the second side of the pad body are opposite, so that the force belt and the movable pulley cooperate with each other; during use, the pad body is located under the patient, and one side of the pad body is fixed to the bed by the connecting belt. The staff pulls the force belt to act on the movable pulley, driving the pad body to deflect and achieve the effect of assisting the patient to turn over.

[0005] However, the above-mentioned related technologies have the following defects. In actual use, the pad body still needs to be placed under the patient's body first, and then the force belt can be pulled to drive the pad body to deflect. This requires that the pad body be laid out before the patient lies down. At the same time, in the process of driving the patient to turn over, medical staff still need to pull the pad body hard to deflect it in order to assist the patient to turn over, which still brings a certain physical burden to the medical staff and is inconvenient to use. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the present application is to provide a medical auxiliary turning device, which can effectively facilitate medical staff to assist patients in turning over.

[0007] The purpose of this application is achieved through the following technical solutions:

[0008] A medical-assisted turning device comprises a bed body, a strip hole is opened on the bed body, the strip hole is opened along the length direction of the bed body, there are two strip holes, and the two strip holes are symmetrically distributed on the bed body along the length direction of the bed body, a push plate is rotatably arranged in each strip hole, a baffle is fixedly arranged on the inner wall of the strip hole, the top of the baffle is used to abut against the bottom of the push plate to limit the deflection angle of the push plate, a mounting rod is arranged on the bed body, the mounting rod is located below the push plate, the mounting rod is arranged in a direction perpendicular to the length of the strip hole, a driving rod is connected between the push plate and the mounting rod, one end of the driving rod is hinged to the push plate, and the other end is slidably arranged on the mounting rod along the length direction of the mounting rod, and a driving assembly is arranged on the mounting rod, and the driving assembly is used to drive the end of the driving rod to move on the mounting rod.

[0009] By adopting the above technical solution, in actual use, when it is necessary to assist the patient to turn over, the driving assembly is started, and the driving assembly drives one end of the driving rod to move on the mounting rod. As the driving rod moves on the mounting rod, the push plate can be driven to deflect upward, thereby achieving the effect of assisting the patient to turn over. In this process, there is no need for medical staff to manually apply force to assist the patient to turn over, which significantly reduces the labor intensity of medical staff and effectively facilitates medical staff to assist patients to turn over.

[0010] In some possible embodiments, the driving assembly includes a driving motor and a lead screw, a sliding groove is opened at the top of the mounting rod along the length direction of the mounting rod, a slider is slidably arranged in the sliding groove, the driving motor is arranged on the mounting rod, the lead screw is rotatably arranged in the sliding groove along the length direction of the sliding groove, the slider is threadedly sleeved on the lead screw, the output shaft of the driving motor is transmission-connected to the lead screw, and the end of the driving rod away from the push plate is hinged to the slider.

[0011] By adopting the above technical solution, when it is necessary to drive the push plate to deflect, the driving motor is started, and the driving motor drives the lead screw to deflect. As the lead screw deflects, the slider can be driven to move in the slide groove. As the slider moves, the driving rod can be driven to move along the length direction of the mounting rod away from the push plate. As the driving rod moves, the push plate can be driven to deflect in the direction away from the bed body. In this process, the transmission is carried out through the mutually engaging threads between the lead screw and the slider. While the transmission is more stable and accurate, the thread transmission has a self-locking effect, which can effectively prevent the slider from slipping in the slide groove, thereby improving the reliability of the overall device during actual use.

[0012] In some possible embodiments, two push plates are rotatably arranged in each bar hole, the rotation axes of the two push plates are coaxially arranged, a bar groove is opened at the bottom of each push plate along the length direction of the bar hole, the bar grooves at the bottom of the two push plates in each bar hole are connected to each other, a bar block is slidably arranged in the bar groove, one end of the driving rod away from the mounting rod is hinged to the bar block, a limiting member is arranged on the bar block, the limiting member is used to limit the position of the bar block in the bar groove, and the mounting rod is slidably arranged on the bed along the length direction of the bar hole;

[0013] Furthermore, it also includes a connecting piece, which is used to connect two push plates located in the same strip hole.

[0014] By adopting the above technical solution, in actual use, since there are two push plates, according to the actual needs of the patient, the mounting rod is moved to the bottom of the corresponding push plate, and then the position of the strip block in the strip groove is limited by the limit piece. After the position of the strip block is limited, the drive motor can be started to drive the corresponding push plate to deflect, so as to realize the deflection of the patient's upper or lower body separately. The two push plates located in the same strip hole can also be connected by a connecting piece as needed. At this time, the two push plates can be driven to deflect at the same time. The position of the mounting rod and whether to connect the push plates can be adjusted according to actual needs, which can effectively improve the scope of application of the device.

[0015] In some possible embodiments, the limit member includes a limit pin, a mounting hole is provided on the side wall of the strip block, the limit pin is slidably arranged in the mounting hole, a limit hole for inserting the limit pin is provided on the inner wall of the strip groove, a limit hole is provided in the strip groove of each push plate, an elastic member is provided on the strip block, the elastic member is used to drive the limit pin to move toward the direction of the limit hole, and a driving member is provided on the strip block, the driving member is used to drive the limit pin to move.

[0016] By adopting the above technical scheme, as the strip block moves in the strip groove, after the mounting hole coincides with the limiting hole, the limiting member can be inserted into the limiting hole under the action of the elastic member, thereby being able to limit the position of the strip block in the strip groove. When it is necessary to adjust the position of the strip block in the strip groove, the limiting member is driven by the driving member to move on the strip block, so that the end of the limiting member is separated from the limiting hole. At this time, the position of the strip block in the strip groove can be adjusted. The operation is convenient and quick, and it has good practicality.

[0017] In some possible embodiments, the driving member is configured as a driving plate, and a connecting hole is opened on the strip block along the axial direction of the limit pin, the connecting hole is connected to the mounting hole, and a connecting block is slidably arranged in the connecting hole, and the driving member is slidably arranged on the strip block, one end of the connecting block is fixedly connected to the driving member, and the other end is fixedly connected to the limit pin.

[0018] By adopting the above technical solution, in actual use, by driving the driving plate to move on the bar block, the driving plate drives the connecting block to move in the connecting hole, and then drives the limit pin to move in the mounting hole. For medical staff, the operation is simpler and more convenient, and has better practicality.

[0019] In some possible embodiments, a ball is rollingly embedded in one end of the limiting pin away from the mounting hole, and the ball is used for rolling contact with the inner wall of the strip groove.

[0020] By adopting the above technical solution, when the strip block moves in the strip groove, the limit pin always has a tendency to move toward the limit hole under the action of the elastic member, and the end of the limit pin will always abut against the inner wall of the strip groove. At this time, by embedding a ball at the end of the limit pin, the sliding friction between the end of the limit pin and the inner wall of the strip groove is converted into rolling friction, thereby significantly reducing the friction force between the end of the limit pin and the inner wall of the strip groove, facilitating the movement of the strip block in the strip groove, and also reducing the wear between the end of the limit pin and the inner wall of the strip groove.

[0021] In some possible embodiments, a mounting frame is fixedly provided on the bed along the length direction of the strip hole, a guide groove is opened on the side wall of the mounting frame along the length direction of the mounting frame, a guide block is slidably provided in the guide groove, the guide block is fixedly connected to the mounting rod, a guide rod is fixedly provided in the guide groove along the length direction of the guide groove, and the guide block is slidably sleeved on the guide rod.

[0022] By adopting the above technical solution, in the process of driving the installation rod to move on the bed, the guide block can be driven to move in the guide groove as the installation rod moves. Since the guide block is slidably mounted on the guide rod, the movement of the guide block in the guide groove can be guided between the guide block and the guide rod, and between the outer wall of the guide block and the inner wall of the guide groove, thereby facilitating the movement of the installation rod to a certain extent.

[0023] In some possible embodiments, the connecting member is configured as a connecting sheet, the two ends of the connecting sheet are respectively fixedly connected to the two push plates located in the same strip hole, a first fixing hole is opened at the bottom of the push plate, a second fixing hole is opened on the connecting sheet, a connecting bolt is slidably penetrated in the second fixing hole, and the connecting bolt is threadedly connected to the first fixing hole

[0024] In summary, the technical solution of the embodiment of the present application has at least the following advantages and beneficial effects:

[0025] 1. The driving assembly drives one end of the driving rod to move on the mounting rod. As the driving rod moves on the mounting rod, the push plate can be driven to deflect upward, thereby achieving the effect of assisting the patient to turn over. In this process, the medical staff does not need to manually apply force to assist the patient to turn over, which significantly reduces the labor intensity of the medical staff;

[0026] 2. The transmission is carried out through the mutually engaged threads between the lead screw and the slider. The transmission is more stable and accurate. At the same time, since the thread transmission has a self-locking effect, it can effectively prevent the slider from slipping in the slide groove, thereby improving the reliability of the entire device during actual use;

[0027] 3. Since there are two push plates, the upper or lower body of the patient can be deflected separately according to the actual needs of the patient. The two push plates in the same strip hole can also be connected by a connecting piece as needed, so that the two push plates can be driven to deflect at the same time;

[0028] 4. By embedding a ball at the end of the limit pin, the sliding friction between the end of the limit pin and the inner wall of the strip groove is converted into rolling friction, thereby significantly reducing the friction between the end of the limit pin and the inner wall of the strip groove, facilitating the movement of the strip block in the strip groove, and also reducing the wear between the end of the limit pin and the inner wall of the strip groove.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] The following reference Figures 1 to 6 This application is described in further detail.

[0038] Reference Figure 1 , 2 A medical auxiliary turning device includes a bed body 1, on which a strip hole 11 is provided, the strip hole 11 is provided along the length direction of the bed body 1, two strip holes 11 are provided, the two strip holes 11 are symmetrically distributed on the bed body 1, and are preferably provided along the length direction of the bed body 1. A push plate 12 is rotatably provided in each strip hole 11, and a baffle plate 13 is fixedly provided on the inner wall of the strip hole 11, and the top of the baffle plate 13 is used to abut against the bottom of the push plate 12 to limit the deflection angle of the push plate 12.

[0039] Reference Figure 2 , 3 A mounting rod 2 is provided on the bed body 1, and the mounting rod 2 is located below the push plate 12. The mounting rod 2 is arranged in a direction perpendicular to the length of the strip hole 11. A driving rod 21 is connected between the push plate 12 and the mounting rod 2. One end of the driving rod 21 is hinged to the push plate 12, and the other end is slidably arranged on the mounting rod 2 along the length direction of the mounting rod 2. A driving assembly 3 is provided on the mounting rod 2, and the driving assembly 3 is used to drive the end of the driving rod 21 to move on the mounting rod 2.

[0040] As an implementation method of this application, refer to Figure 3The driving assembly 3 includes a driving motor 31 and a lead screw 32. A slide groove 33 is opened at the top of the mounting rod 2 along the length direction of the mounting rod 2. A slider 34 is slidably arranged in the slide groove 33. The driving motor 31 is arranged on the mounting rod 2. The lead screw 32 is rotatably arranged in the slide groove 33 along the length direction of the slide groove 33. The slider 34 is threadedly sleeved on the lead screw 32. The output shaft of the driving motor 31 is transmission-connected to the lead screw 32. The slider 34 is hinged to the end of the driving rod 21 away from the push plate 12.

[0041] When it is necessary to drive the push plate 12 to deflect, the drive motor 31 is started, and the drive motor 31 drives the lead screw 32 to rotate. As the lead screw 32 rotates, the slider 34 can be driven to move in the slide groove 33. As the slider 34 moves, the end of the drive rod 21 away from the push plate 12 can be driven to move along the length direction of the mounting rod 2. As the drive rod 21 moves, the push plate 12 can be driven to deflect. In this process, the transmission is carried out through the mutually engaged threads between the lead screw 32 and the slider 34. At the same time, the transmission is more stable and accurate. Since the thread transmission has a self-locking effect, it can effectively prevent the slider 34 from slipping in the slide groove 33, thereby improving the reliability of the overall device during actual use.

[0042] Reference Figure 1 , 4 And 5. Two push plates 12 are rotatably arranged in each strip hole 11, and the two push plates 12 are respectively arranged at the front and rear ends in the strip hole 11, and the rotation axes of the two push plates 12 are coaxially arranged. A strip groove 4 is opened at the bottom of each push plate 12 along the length direction of the strip hole 11, and the strip grooves 4 at the bottom of the two push plates 12 in each strip hole 11 are connected to each other. A strip block 41 is slidably arranged in the strip groove 4, and one end of the driving rod 21 away from the mounting rod 2 is hinged to the strip block 41, and a limiting member 5 is arranged on the strip block 41. The limiting member 5 is used to limit the position of the strip block 41 in the strip groove 4, and the mounting rod 2 is slidably arranged on the bed body 1 along the length direction of the strip hole 11.

[0043] In actual use, since two push plates 12 are provided, a mounting rod 2 and a driving assembly 3 used in conjunction with the same may be provided under each push plate 12. Alternatively, only one mounting rod 2 and a driving assembly 3 used in conjunction with the same may be provided in one strip hole 11. A preferred solution is that a mounting rod 2 and a driving assembly 3 used in conjunction with the same are provided under each push plate 12.

[0044] According to the actual needs of the patient, the mounting rod 2 is moved to the bottom of the corresponding push plate 12, and then the position of the strip block 41 in the strip groove 4 is limited by the limit member 5. After the position of the strip block 41 is limited, the driving motor 31 can be started to drive the corresponding push plate 12 to deflect, so as to realize the deflection of the patient's upper body or lower body alone. The two push plates 12 located in the same strip hole 11 can also be connected using the connecting member 7 as needed. At this time, the two push plates 12 can be driven to deflect at the same time. The position of the mounting rod 2 and whether to connect the push plate 12 can be adjusted according to actual needs, which can effectively improve the scope of application of the device.

[0046] As the strip block 41 moves in the strip groove 4, when the mounting hole 51 is aligned with the limiting hole 52, the limiting member 5 can be inserted into the limiting hole 52 under the action of the elastic member 53, so that the position of the strip block 41 in the strip groove 4 can be limited. When it is necessary to adjust the position of the strip block 41 in the strip groove 4, the limiting member 5 is driven by the driving member 54 to move in the strip block 41, so that the end of the limiting member 5 is separated from the limiting hole 52. At this time, the position of the strip block 41 in the strip groove 4 can be adjusted. The operation is convenient and quick, and it has good practicality.

[0047] As an implementation method of this application, refer to Figure 4 , 5 The elastic member 53 is configured as a compression spring, and the elastic member 53 is disposed in the mounting hole 51 .

The driving member 54 is slidably arranged on the strip block 41, and one end of the connecting block 56 is fixedly connected to the driving member 54, and the other end is fixedly connected to the limit pin.

[0049] In actual use, by driving the driving plate to move on the bar block 41, the driving plate drives the connecting block 56 to move in the connecting hole 55, and then drives the limit pin to move in the mounting hole 51. For medical staff, the operation is simpler and more convenient, and has better practicality.

[0050] Reference Figure 4 , 5 A ball 57 is rollingly embedded in one end of the limiting pin away from the elastic member 53 , and the ball 57 is used for rolling contact with the inner wall of the strip groove 4 .

[0051] When the strip block 41 moves in the strip groove 4, the limit pin always has a tendency to move toward the limit hole 52 under the action of the elastic member 53, and the end of the limit pin will always abut against the inner wall of the strip groove 4. At this time, by embedding a ball 57 at the end of the limit pin, the sliding friction between the end of the limit pin and the inner wall of the strip groove 4 is converted into rolling friction, thereby significantly reducing the friction between the end of the limit pin and the inner wall of the strip groove 4, facilitating the movement of the strip block 41 in the strip groove 4, and also reducing the wear between the end of the limit pin and the inner wall of the strip groove 4.

[0052] Reference Figure 3 A mounting frame 6 is fixedly provided on the bed body 1 along the length direction of the strip hole 11, a guide groove 61 is opened on the side wall of the mounting frame 6 along the length direction of the mounting frame 6, a guide block 62 is slidably provided in the guide groove 61, the guide block 62 is fixedly connected to the mounting rod 2, a guide rod 63 is fixedly provided in the guide groove 61 along the length direction of the guide groove 61, and the guide block 62 is slidably sleeved on the guide rod 63.
