Technical Field
[0001] The utility model relates to the medical field, in particular to a turning device for assisting patients in adjusting their body positions. Background Art
[0002] In hospital inpatient departments, beds are a common feature, providing resting areas for patients and facilitating treatment and care by medical staff. The bed's backrest can be adjusted to adjust the patient's position via a rocker at the foot of the bed or an electronically controlled mechanism. This position effectively reduces right cardiac preload, respiratory muscle resistance, and abdominal wall tension, among other therapeutic and nursing benefits, promoting recovery and facilitating other types of care. Adjusting the position can alleviate fatigue or provide massage, and also allows patients to eat and drink in bed.
[0003] However, in the actual posture adjustment process, there are the following problems:
[0004] Due to the influence of body weight, the patient's body can easily slide toward the end of the bed. At this time, family members or medical staff need to drag the patient to put the patient in a suitable posture.
[0005] If the patient slides down too far, the bed needs to be leveled again, the patient needs to be moved back to their original position, and then the patient's upper body needs to be lifted up again. This operation is time-consuming and labor-intensive, reducing the work efficiency of medical staff and affecting the subsequent treatment progress of other patients.
[0006] Therefore, a hospital bed that can adjust the patient's position conveniently and quickly is needed. Utility Model Content
[0007] The purpose of the utility model is to provide a turning device for assisting in adjusting the patient's body position. With only simple operating steps, the patient's body position can be quickly adjusted in a raised-back state, and the upper body and head of the patient can be fully supported in a raised-back state, and treatment and nursing operations can be performed conveniently for the patient in a sideways state.
[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0009] A turning device for assisting in adjusting a patient's body position comprises a bed frame, a mattress, a baffle, an adjustment belt and a control component, wherein the baffle is movably arranged on the side of the bed frame, the adjustment belt comprises a belt body and two transmission shafts, the two transmission shafts are respectively arranged at positions of the bed frame corresponding to the head and foot of the bed, the belt body simultaneously surrounds and is connected to the two transmission shafts, the belt body is located on a side of the mattress away from the bed frame, and the belt body can completely cover the mattress, and the control component is arranged on the bed frame to control the rotation of the transmission shafts.
[0010] Compared with the prior art, the turning device for assisting the patient in adjusting the body position using the above technical solution has the following beneficial effects:
[0011] 1. The turning device of the present invention is used to assist in adjusting the patient's body position. By controlling the rotation of the transmission shaft and the driving effect of the belt body, the patient in a sliding state is dragged toward the head of the bed. There is no need for family members or medical staff to make time-consuming and laborious adjustments, and the purpose of body position adjustment can be achieved quickly and accurately.
[0012] Second, because the coverage area of the belt is much larger than the patient's entire body, the belt can achieve an adjustment effect on the patient's entire body when it moves, thereby further increasing the efficiency and convenience of the position adjustment operation.
[0013] Preferably, the control element includes a servo motor and a control button. The servo motor is connected to one of the transmission shafts, and the control button is connected to the servo motor via an electrical circuit. The transmission shaft can be rotated manually or electronically. The electronically controlled structure offers faster and more accurate adjustments, further improving the work efficiency of medical personnel.
[0014] Preferably, the bed frame is provided with guide rails at the head and foot of the bed, the guide rails being longer than the width of the bed frame. A drive shaft is disposed in the guide rails, and the drive shaft's length matches that of the guide rails. The belt does not exceed the length of the drive shaft. The baffles are rotatably connected to the bed frame via extension plates, and the distance between the baffles on both sides is no less than the length of the guide rails, allowing the belt to move along the length of the guide rails. The guide rails, which extend beyond the width of the bed frame, provide effective support for the belt on both sides of the bed frame. This maintains the belt's supportive function when controlling the belt's left and right displacement, facilitating subsequent repositioning. By controlling the belt's displacement, the limbs of patients lying sideways are prevented from excessively pressing against the rails, thus avoiding discomfort to the patient and facilitating back treatment and care by medical personnel. The baffles, which are appropriately extended outward, provide space for the belt's displacement.
[0015] Preferably, a sleeve is provided on the outside of the transmission shaft, and the inside of the belt body meshes with the sleeve, and the sleeve meshes with the transmission shaft. The meshing of the belt body, sleeve, and transmission shaft does not affect the normal function of driving the belt body, and provides a hard structure between the belt body and the transmission shaft to facilitate the movement of the belt body through the sleeve, thereby avoiding the problem of damage caused by friction between the belt body and the transmission shaft.
[0016] Preferably, both transmission shafts are connected to servo motors. Through the dual-motor structure, sufficient force is applied to the movement of the belt body, and the operation of controlling the movement of the belt body is more accurate and quick.
[0017] Preferably, the mattress is composed of multiple cushions. The cushion near the head of the bed is the upper body cushion. The upper body cushion is movable back and forth along the length of the bed frame and includes a locking structure for limiting the position of the upper body cushion. When standing up, the upper body cushion is controlled to be upward and locked so that it fully cushions the patient's upper body and head, thereby increasing patient comfort and facilitating the patient's recovery effect when standing up.
[0018] Preferably, the locking structure includes a convex tooth portion, a limiting tooth, and an unlocking button. The position of the bed frame corresponding to the upper body cushion is an adjustment plate. The convex tooth portion is provided on the side wall of the upper body cushion facing the adjustment plate. A plurality of limiting teeth are provided, evenly spaced along the length of the adjustment plate, and located on the side of the adjustment plate facing the upper body cushion. The unlocking button is provided on the adjustment plate and is simultaneously connected to the plurality of limiting teeth via a connecting rod. The connecting rod is connected to the interior of the adjustment plate via a return spring. The limiting teeth restrict the convex tooth portion to achieve the purpose of locking between the adjustment plate and the upper body cushion; and the elastic characteristics of the return spring can be used to control the limiting tooth to move away from the convex tooth portion to achieve the purpose of unlocking the upper body cushion.
[0019] Preferably, both the side of the convex teeth facing the head of the bed and the side of the limiting teeth facing the foot of the bed are provided with inclined portions. Utilizing the special structure of the inclined portions, when force is applied to push the upper body cushion, the force of the convex teeth is applied to the limiting teeth and the connecting rod, causing the return spring to contract, thereby pushing the upper body cushion upward to achieve adjustment, further improving the efficiency of the medical staff's adjustment work.

[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] like Figures 1 to 8 The turning device shown in the figure for assisting the patient in adjusting the body position comprises a bed frame 1 , a mattress 2 , a baffle 3 , an adjustment belt 4 and a control part 5 .
[0031] The structure of the bed frame 1 can be similar to existing methods of controlling partial tilting of the frame using cranks or electric control buttons. For example, the XINYUCHEN brand hand-cranked hospital bed utilizes a manual rotation of the rocker at the foot of the bed, which causes a mechanical structure underneath to lift the bedboard to a specific angle, thereby lifting the patient's upper body.
[0032] The baffle 3 is movably arranged on the side of the bed frame 1. The adjustment belt 4 includes a belt body 40 and two transmission shafts 41. The two transmission shafts 41 are respectively arranged at the positions of the bed frame 1 corresponding to the head and foot of the bed. The belt body 40 is simultaneously wrapped around and connected to the two transmission shafts 41. The belt body 40 is located on the side of the mattress 2 away from the bed frame 1, and the belt body 40 can completely cover the mattress 2. The control part 5 is arranged on the bed frame 1 to control the rotation of the transmission shaft 41.
[0033] Regarding the structure of the control component 5, the transmission shaft 41 can be driven to rotate manually, or an electronically controlled structure can be adopted. In this embodiment, the control component 5 includes a servo motor 50 and a control button 51. The servo motor 50 is connected to one of the transmission shafts 41, and the control button 51 is connected to the servo motor 50 through a circuit.
[0034] In order to prevent the patient from being too close to the baffle 3 when lying sideways, the bed frame 1 is provided with guide rails 6 at the positions corresponding to the head and foot of the bed. The length of the guide rails 6 exceeds the width of the bed frame 1. The transmission shaft 41 is arranged in the guide rail 6, and the length of the transmission shaft 41 is adapted to the guide rail 6. The belt body 40 does not exceed the length of the transmission shaft 41.
[0035] In order to match the usage of the guide rail 6, the baffle 3 is rotatably connected to the bed frame 1 through the extension plate 30, and the distance between the baffles 3 on both sides is not less than the length of the guide rail 6, and the belt body 40 can be displaced along the length of the guide rail 6.
[0036] In order to simultaneously meet the transmission belt function of the belt body 40 and the left and right displacement requirements of the belt body 40, a sleeve 7 is provided on the outside of the transmission shaft 41, the inner side of the belt body 40 is engaged with the sleeve 7, and the sleeve 7 is engaged with the transmission shaft 41.
[0037] In addition, in order to enhance the effect of adjusting the patient's body position, both transmission shafts 41 are connected to a servo motor 50 and a corresponding control button 51 .
[0038] In order to fully support the upper body and head when the patient raises his back, the mattress 2 is composed of multiple cushions. The cushion near the head of the bed is the upper body cushion 20. The upper body cushion 20 can be moved back and forth along the length direction of the bed frame 1, and also includes a locking structure 8 for limiting the position of the upper body cushion 20.
[0039] The locking structure 8 includes a convex tooth portion 80, a limiting tooth 81 and an unlocking button 82. The position of the bed frame 1 corresponding to the upper body cushion 20 is the adjustment plate 10. The convex tooth portion 80 is provided on the side wall of the upper body cushion 20 facing the adjustment plate 10. There are multiple limiting teeth 81, and the multiple limiting teeth 81 are evenly spaced along the length direction of the adjustment plate 10, and the limiting teeth 81 are located on the side of the adjustment plate 10 facing the upper body cushion 20. The unlocking button 82 is provided on the adjustment plate 10, and the unlocking button 82 is connected to the multiple limiting teeth 81 at the same time through a connecting rod 83, and the connecting rod 83 is connected to the inside of the adjustment plate 10 through a reset spring 84.
[0040] In addition, in order to facilitate rapid adjustment of the position of the upper body cushion body 20, an inclined portion 9 is provided on the side of the convex tooth portion 80 facing the head of the bed and the side of the limiting tooth 81 facing the foot of the bed.
[0041] The following is how this embodiment is used:
[0042] If the patient's upper body needs to be lifted to a sitting position in bed, the portion of the bed frame 1 where the upper body is located is tilted by a crank or an electrically controlled mechanism. Under the influence of the patient's weight, the patient's body and the bed sheet slide toward the foot of the bed. The control knob 51 rotates the two drive shafts 41. The meshing of the drive shafts 41, the sleeve 7, and the belt 40 causes the belt 40 to move toward the head of the bed, adjusting the patient's position to a suitable posture.
[0043] The upper body cushion body 20 moves toward the end of the bed, and the medical staff can hold the upper body cushion body 20 with their hands and push the upper body cushion body 20 upwards. Figure 8As shown, the inclined portion 9 of the convex tooth portion 80 presses on the inclined portion 9 of the limiting tooth 81, and the force applied by the medical staff to the limiting tooth 81 and the connecting rod 83 causes the return spring 84 to be forced to contract, driving the limiting tooth 81 to temporarily retract into the adjustment plate 10, allowing the upper body pad 20 to move upward smoothly; when the upper body pad 20 moves to the desired position, the upper body pad 20 is released, the return spring 84 is released and pushes the limiting tooth 81 to return to its original position. Since the upper side of the limiting tooth 81 is a flat structure, the convex tooth portion 80 and the upper body pad 20 are limited. If it is necessary to lower the upper body pad 20, the release button 82 can be pressed to cause the return spring 84 to contract, causing the connecting rod 83 and the limiting tooth 81 to move, releasing the restriction of the limiting tooth 81 on the convex tooth portion 80, and then the upper body pad 20 naturally moves downward. When the upper body pad 20 is adjusted to the desired position, the pressure on the release button 82 can be released.
[0044] If it is necessary to apply medicine or other nursing operations on the patient's back, the bed frame 1 can be reset by the crank or the electric control structure, and the patient can be placed in a lying position. When the patient is lying or there is no one on the bed, the sleeve 7 and the belt body 40 can be pushed to form a Figure 5 In the state shown, even if the patient lies sideways, his body is in the middle of the bed, which is convenient for medical staff to perform treatment or care, and the patient's body will not stick to the baffle 3.
[0045] The above is a preferred embodiment of the present invention. Those skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered as within the scope of protection of the present invention.
