Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a rocking bed angle indicating device. Background Art

[0002] At present, most of the hospital beds used in the inpatient department can adjust the lifting angle of the backboard of the hospital bed through the rocker at the end of the bed to adjust the patient's body position, and some hospital beds can also be adjusted through an electric control structure. During daily treatment and nursing, according to the different conditions of patients, the patients are adjusted to a specific body position, which has various therapeutic effects and nursing functions such as reducing the right heart preload, reducing the resistance of respiratory muscle movement, and reducing the abdominal wall tension, and plays a role in promoting the recovery of patients.

[0003] This adjustment method needs to consider the current condition and physical function of the patient, and the lifting angle cannot be blindly adjusted. For example, for pneumonia patients, the most suitable elevation angle of the bed board is between 30 degrees and 45 degrees. If it is lower than 30 degrees, it may endanger the life of the patient; for another example, when the patient eats in bed, if the elevation angle of the bed board is not appropriate, it may cause the patient to have reflux and aspiration, and there will also be danger.

[0004] However, the adjustment structures of most existing hospital beds are manually adjusted, and the current lifting angle of the bed board cannot be determined. Most medical staff use such structures to judge the lifting angle intuitively, and generally family members do not think about the problem of the lifting angle for the recovery of patients, which easily leads to a huge deviation in the actual lifting angle.

[0005] Therefore, a rocking bed angle indicating device is needed that can intuitively display the lifting angle during manual adjustment and can guide family members on what angle should be lifted. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a rocking bed angle indicating device, which can guide the user to lift the hospital bed at the correct angle, can intuitively and real-time display the current angle, and can timely remind and lock when the angle is inappropriate, so as to avoid problems caused by too high or too low lifting angle.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A rocking bed angle indicating device, the hospital bed includes a bed board and a movable board rotatably connected to the bed board. A rocking handle is provided at the foot of the hospital bed, and the rocking handle drives the movable board to flip or fall through an existing rocking bed control structure. It includes an angle board and a pointer. The angle board is provided at the end board of the bed, and the angle board is respectively provided with a plurality of function prompt areas and revolution number prompt marks corresponding to different angle ranges. The pointer is movably connected to the angle board, and the pointer is connected to the rocking handle through a linkage structure. When the rocking handle rotates a specific number of revolutions, the pointer points to the corresponding function prompt area and the position where the revolution number prompt mark is located; the linkage structure includes a driving gear and a driven gear. The driving gear is provided at the rocking handle, the driven gear is provided in the middle of the angle board, and the pointer is connected to the driven gear through a rotating shaft. The driving gear and the driven gear are meshed, and the number of convex teeth on the driven gear exceeds the number of convex teeth on the driving gear; the function prompt area is provided with an angle prompt mark and a disease indication mark applicable thereto; a limiting area is provided on the outer periphery of the angle board, and a sound alarm and a light alarm are provided on the angle board. When the pointer moves beyond the range of the limiting area, the sound alarm and the light alarm operate.

[0009] Compared with the prior art, the rocking bed angle indicating device adopting the above technical scheme has the following beneficial effects:

[0010] 1. By adopting the rocking bed angle indicating device of the present utility model, according to the patient's condition, referring to the function prompt area and the corresponding revolution number prompt mark, the number of rotations required to lift to the current condition angle can be quickly determined, and then the rocking handle can be rotated for the lifting operation, and the lifted angle can be the correct angle, which can effectively avoid a series of problems caused by improper lifting angle.

[0011] 2. And through the linkage structure, the pointer can move synchronously according to the movement of the rocking handle, so that the pointer points to the position corresponding to the angle on the function prompt area, so as to view the current angle situation in real time during the lifting operation, avoid the problem of over-adjustment and the need for resetting, and effectively save the time and energy consumed by the lifting operation; in addition, since the lifted angle situation can be fed back through the function prompt area pointed by the pointer, it is convenient for medical staff to quickly clarify during ward rounds and adjust according to the subsequent condition.

[0012] During the process of driving the pointer to move by using the gear transmission effect, since the number of convex teeth on the driven gear is relatively large, when the rocking handle rotates multiple circles, the pointer only moves a short distance, which conforms to the actual situation of more rotation circles and less lifting angle; and because the convex teeth on the gear are evenly spaced, fine and precise adjustment of the angle can be achieved.

[0013] Through the angle prompt identifier and the corresponding disease identifier, the lifting angle corresponding to the disease identifier can be matched, and then combined with the corresponding number-of-turns prompt identifier to achieve the correspondence among the disease condition, the angle, and the number of turns, which is further convenient for family members and medical staff to understand and clarify, and effectively improves the work efficiency of medical staff.

[0014] Using a variety of auditory and visual feedback methods to maximally remind family members and medical staff. When feedback is given to medical staff, it is convenient for medical staff to quickly locate the bed where the problem occurs. This kind of alarm structure can also maximally improve the work efficiency of medical staff.

[0015] Preferably, a chute is provided on the outer periphery of the angle plate. A lower limit slider and an upper limit slider are provided in the chute, and the angle corresponding to the upper limit slider is larger than the angle corresponding to the lower limit slider. The position of the angle interval between the lower limit slider and the upper limit slider is the limit area. The pointer, the lower limit slider, and the upper limit slider are all made of conductive materials. The sound alarm and the light alarm are respectively connected to the pointer, the lower limit slider, and the upper limit slider through circuits. When the pointer contacts the lower limit slider or the pointer contacts the upper limit slider, the sound alarm and the light alarm operate. Utilizing the conductive characteristics of the pointer, the lower limit slider, and the upper limit slider, when the pointer contacts the lower limit slider or the pointer contacts the upper limit slider, the circuits of the sound alarm and the light alarm can be connected and operated, thereby realizing the matching function of the limit area and the alarm structure.

[0016] Preferably, a support rod is connected to the side of the pointer end facing the chute. A locking device is provided inside the angle plate. There is a slot on the left side of the locking device for the support rod to enter and exit, and a limiting plate is rotatably connected at the slot. A baffle for restricting the leftward movement of the limiting plate is also provided on the left side of the locking device. An unlocking member for controlling the locking device to move away from the support rod is also included. During the displacement of the support rod, at the moment of excessive adjustment (i.e., the moment of excessive displacement of the pointer), the support rod will push open the limiting plate and enter the locking device by itself. And due to the blocking effect of the baffle, the support rod cannot push open the limiting plate in the reverse direction, thereby realizing the restriction of the state of the support rod. When cooperating with the above alarm structure, the operation state of the alarm structure can be maintained, and medical staff can timely and fully admonish and remind family members of how to operate next.

[0017] Preferably, the unlocking member includes a button, a movable rod, and a return spring. The button is movably arranged on the angle plate through the return spring, and the button is connected to the locking device through the movable rod. An opening adapted to the support rod is provided on the side of the locking device facing the pointer. When controlling the displacement of the movable rod through the button, the locking device will displace towards the inside of the hospital bed, and then the support rod can be disengaged from the locking device through the opening to achieve the unlocking purpose, and it is convenient for subsequent repeated use through the return spring.

[0018] Preferably, a plurality of card slots are provided in the sliding groove, and both the lower limit slider and the upper limit slider can be disengaged from or engaged with the card slots. By respectively adjusting the positions of the lower limit slider and the upper limit slider, the purpose of adjusting the limit area is achieved, so as to match the patient corresponding to the current hospital bed and be applicable to the situation of the mobility of inpatients.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] As Figures 1 to 7 shown in the rocking bed angle indicating device, wherein the hospital bed 1 involved in the present application is a commonly used hand-cranked hospital bed 1 in existing hospitals, that is, the hospital bed 1 includes a bed board 10 and a movable board 11 rotatably connected to the bed board 10. A rocking handle 2 is provided at the end of the hospital bed 1, and the rocking handle 2 drives the movable board 11 to flip or fall through an existing rocking bed control structure.

[0029] Regarding the control structure of the rocking bed, the manual or electric control methods of the prior art can be referred to. For example, for the hand-cranked hospital bed 1 of the XINYUCHEN brand, the specific principle is that by manually rotating the rocker at the end of the bed, the mechanical structure under the end of the bed conveys the acting force to the support rod or support crossbeam under the movable plate 11, and the support crossbeam or the longer edge of the bed frame will lift or lower by a corresponding angle, realizing the back-lifting function of the hospital bed 1, so that the upper body of the patient can be lifted under force.

[0030] The rocking bed angle indicating device includes an angle plate 3 and a pointer 4. The angle plate 3 is arranged at the end plate of the bed, and the angle plate 3 can be assembled at the end plate of the bed through a screw or a clamping structure.

[0031] Among them, for the convenience of medical staff or family members to quickly and clearly know the angle to be lifted, the angle plate 3 is respectively provided with a plurality of function prompt areas 5 and revolution number prompt marks 6 corresponding to different angle intervals, and the function prompt area 5 is provided with an angle prompt mark 50 and an applicable disease mark 51.

[0032] In this embodiment, to avoid a large amount of text affecting the viewing of the accompanying drawings of the specification, this embodiment uses a horizontal line to represent the disease mark 51, and in actual use, it is a specific disease description.

[0033] The pointer 4 is movably connected to the angle plate 3, and the pointer 4 is connected to the crank 2 through a linkage structure 7. When the crank 2 rotates a specific number of turns, the pointer 4 points to the corresponding function prompt area 5 and the position where the revolution number prompt mark 6 is located.

[0034] Regarding the linkage structure 7, a gear meshing structure can be adopted, or a rope-pulling structure can be arranged at the movable plate 11 of the hospital bed 1 (when the movable plate 11 is lifted, it drives the pointer 4 to move). In this embodiment, considering the accuracy when gears are meshed, a gear meshing structure is selected, that is, the linkage structure 7 includes a driving gear 70 and a driven gear 71. The driving gear 70 is arranged at the crank 2, the driven gear 71 is arranged in the middle of the angle plate 3, the pointer 4 is connected to the driven gear 71 through a rotating shaft 40, and the driving gear 70 and the driven gear 71 are meshed and connected.

[0035] In order to avoid the problem that the pointer 4 cannot point to the correct angle due to the excessive rotation amplitude of the rotating shaft 40, and to be able to correspond to the angle of the lifted movable plate 11, the number of convex teeth on the driven gear 71 exceeds the number of convex teeth on the driving gear 70, that is, when the crank 2 rotates multiple turns, the rotating shaft 40 only moves a small distance.

[0036] To prevent family members from randomly adjusting the rotation angle of the movable plate 11, avoid the deterioration of the condition caused by incorrect sitting-up postures, and for medical staff to be able to detect this situation in time, this embodiment is also provided with a limit area 8, an alarm structure and a locking structure during adjustment.

[0037] The outer periphery of the angle plate 3 is provided with a limiting area 8. The alarm structure is a sound alarm 30 and a light alarm 31 provided on the angle plate 3. When the pointer 4 moves beyond the range of the limiting area 8, the sound alarm 30 and the light alarm 31 operate. Among them, the sound alarm 30 can adopt a buzzer or a voice player in the prior art, and the light alarm 31 can adopt an LED light strip in the prior art. Batteries can be installed in the sound alarm 30 and the light alarm 31 or they can be charged by an external power supply.

[0038] Regarding the way to trigger the reaction of the alarm structure, the way of transmitting signals through a micro switch can be adopted, or the way of connecting circuits with the conductive material in this embodiment can be adopted, that is, a chute 32 is provided on the outer periphery of the angle plate 3. A lower limit slider 80 and an upper limit slider 81 are provided in the chute 32, and the angle corresponding to the upper limit slider 81 is larger than the angle corresponding to the lower limit slider 80. The position of the angular interval between the lower limit slider 80 and the upper limit slider 81 is the limiting area 8. The pointer 4, the lower limit slider 80 and the upper limit slider 81 are all made of conductive materials (such as iron or copper). The sound alarm 30 and the light alarm 31 are respectively connected to the pointer 4, the lower limit slider 80 and the upper limit slider 81 through circuits. When the pointer 4 contacts the lower limit slider 80 or the pointer 4 contacts the upper limit slider 81, the sound alarm 30 and the light alarm 31 operate.

[0039] The specific locking structure is that a lock 9 is provided inside the angle plate 3. A support rod 41 is connected to one side of the end of the pointer 4 facing the chute 32. A slot 90 for the support rod 41 to enter and exit is provided on the left side of the lock 9, and a limit plate 91 is rotatably connected at the slot 90. A baffle 92 for restricting the leftward movement of the limit plate 91 is also provided on the left side of the lock 9. An unlocking member for controlling the lock 9 to move away from the support rod 41 is also included.

[0040] Among them, the lock 9 is not limited to the one shown in the figure. According to the lifting angles commonly used in hospitals, locks 9 and corresponding unlocking members can be provided corresponding to the lower limit slider 80 and the upper limit slider 81, and the slots corresponding to the slots 90 will also be adjusted adaptively according to the set positions.

[0041] The unlocking member includes a button 93, a movable rod 94 and a return spring. The button 93 is movably provided on the angle plate 3 through the return spring, and the button 93 is connected to the lock 9 through the movable rod 94. An opening adapted to the support rod 41 is provided on the side of the lock 9 facing the pointer 4.

[0042] In addition, to be applicable to patients with different conditions, the positions of the lower limit slider 80 and the upper limit slider 81 can be adjusted, that is, the range and position of the limiting area 8 can be adjusted, that is, a plurality of card slots 33 are provided in the chute 32, and the lower limit slider 80 and the upper limit slider 81 can be disengaged from or clamped in the card slots 33.

[0043] The following is the usage method of this embodiment:

[0044] First, according to the disease suffered by the patient and the current severity of the disease, if the patient is on mechanical ventilation, select the applicable disease mark 51 on the function prompt area 5. For example, if the patient needs to lift the movable plate 11 45°, according to the circle number prompt mark 6 corresponding to the 45° angle prompt mark 50, rotate the crank handle 2 a specific number of circles.

[0045] During the rotation control of the crank 2, if Figure 4 As shown, when the crank 2 and the driving gear 70 rotate counterclockwise, the driven gear 71 and the rotating shaft 40 are forced to rotate clockwise, as shown in FIG. Figure 3 As shown, the rotating shaft 40 drives the pointer 4 to rotate synchronously in the clockwise direction, and the pointer 4 will gradually move in the direction of the 45° angle prompt mark 50.

[0046] At this time, the angle range of the limit zone 8 is between 0° and 60°. When the pointer 4 points to the 45° angle indication mark 50, the current limit zone 8 meets the angle required for this type of patient to raise their back. If the family members do not pay attention and excessively rotate the crank 2, the pointer 4 will continue to move and contact the upper limit slider 81, so that the internal circuit of the sound alarm 30 is connected, the internal circuit of the light alarm 31 is connected, the sound alarm 30 emits a sound to remind the family members and the medical staff on duty, and the light alarm 31 emits a flashing light to remind the medical staff where the bed 1 is.

[0047] At the same time Figure 6 and Figure 7 As shown, since the limit plate 91 is rotatably connected to the slot 90, the support rod 41 at the end of the pointer 4 will push the limit plate 91 into the interior of the lock 9, and due to the obstruction of the baffle 92, the support rod 41 cannot push the limit block in the opposite direction, so that the support rod 41 is locked in the lock 9. After the medical staff discovered the problem, they informed the family of the error and pressed the button 93. Since the button 93 is connected to the lock 9 through the movable rod 94, and the lock 9 is provided with an opening for the support rod 41 on the side facing the pointer 4, the lock 9 will be as shown. Figure 7 The indicated direction displacement causes the support rod 41 to disengage from the locker 9 and controls the pointer 4 to return to the current limit zone 8, so that the internal circuits of the sound alarm 30 and the light alarm 31 are disconnected, and the alarm is released.

[0048] If it is to be suitable for patients with different conditions, the lower limit slider 80 and the upper limit slider 81 can be manually controlled to disengage from the slot 33 and inserted into other slots 33 to form a new limit zone 8.

[0049] The above are the preferred embodiments of the present utility model. For those of ordinary skill in the art, without departing from the principle of the present utility model, several variations and improvements can still be made, which should also be regarded as the protection scope of the present utility model.
