Description

Technical Field

[0001] The present invention relates to a nursing bed, specifically a nursing bed for elderly care and rehabilitation. Background Art

[0002] In the field of elderly care and rehabilitation, as an important auxiliary device, the performance of the nursing bed directly affects the rehabilitation experience of patients and the nursing efficiency. At present, the nursing beds for elderly care and rehabilitation on the market generally have problems of complex structure and cumbersome operation.

[0003] In terms of functions, the existing nursing beds have single functions and lack of integrated design, and cannot meet the needs of patients' cleaning care and conventional medical operations at the same time. For example, when cleaning a patient with inconvenient movement with liquid medicine, an additional stirring device often needs to be equipped, which increases the complexity of the nursing process; and the design of the hanging bracket for medical equipment is unreasonable, and it is difficult to stably hang the infusion device, which poses a safety hazard.

[0004] In addition, in terms of space utilization, the positions of the auxiliary devices of most nursing beds are not adjustable, and they will occupy a large amount of space when not in use, seriously affecting the family members' accompanying and daily care activities, and greatly reducing the practicality and space compatibility of the nursing bed.

[0005] Therefore, the technical personnel in this field have proposed a nursing bed for elderly care and rehabilitation to solve the problems raised in the above background. Summary of the Invention

[0006] The purpose of the present invention is to provide a nursing bed for elderly care and rehabilitation to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A nursing bed for elderly care and rehabilitation includes a bed body. A sliding substrate is slidably connected to the side of the bed body. A support sleeve is fixedly connected to the sliding substrate. The top of the support sleeve is rotatably connected to a top plate. A plurality of hooks are connected below the top plate. An adjusting slider is slidably arranged inside the support sleeve. A threaded shaft is rotatably connected inside the support sleeve. The adjusting slider is threadedly connected to the threaded shaft. A box body is fixedly connected to the adjusting slider. A mixing assembly is arranged inside the box body. A driving assembly for driving the threaded shaft to rotate is arranged below the sliding substrate, and the driving assembly is also used for driving the mixing assembly to mix.

[0009] As a further solution of the present invention: The support sleeve is provided with a first notch and a second notch. The first notch and the second notch are opened along the axial direction of the support sleeve. The second notch is located above the first notch and communicates with the first notch. The corresponding central angle degree of the second notch is greater than the central angle degree of the first notch.

[0010] As a further solution of the present invention: the first notch faces away from the bed body, the corresponding central angle of the second notch is 180°, and when the adjustment slider abuts against the edge position of the second notch, the box body is located above the bed body.

[0011] As a further solution of the present invention: the driving assembly includes a motor, a horizontal driving shaft is fixedly connected to the motor rotor, a first driving bevel gear is fixedly connected to the outside of the horizontal driving shaft, and a first driven bevel gear is fixedly connected to the bottom of the threaded shaft. The first driving bevel gear meshes with the first driven bevel gear.

[0012] As a further solution of the present invention: a spring is sleeved on the outside of the threaded shaft and is located inside the support sleeve. When the adjustment slider moves to the bottommost part and disengages from the threaded position of the threaded shaft, the adjustment slider abuts against the thread of the threaded shaft under the elastic force of the spring.

[0013] As a further solution of the present invention: when the adjustment slider is at the bottommost part, the mixing assembly cooperates with the driving assembly for mixing. The mixing assembly includes a mixing shaft rotatably connected to the box body, mixing blades are arranged on the outside of the mixing shaft, a square hole is opened at the bottom of the mixing shaft, and a transmission unit for driving the mixing shaft to rotate is arranged on the driving assembly.

The one-way transmission mechanism is located between the first driving bevel gear and the second driving bevel gear.

[0015] As a further solution of the present invention: the one-way transmission mechanism includes an outer sleeve ring and an inner rotating ring. An inclined groove is opened on the outer sleeve ring, a driving tooth is rotatably connected to the inner rotating ring through a torsion spring, the driving tooth is matched with the inclined groove, and the outer sleeve ring and the inner rotating ring are respectively connected to both ends of the horizontal driving shaft.

[0016] As a further solution of the present invention: a locking bolt is connected to the sliding substrate, and the locking bolt is used to lock the relative position between the sliding substrate and the bed body.

[0017] As a further solution of the present invention: a water outlet pipe for discharging liquid is connected to the bottom of the box body.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: ① In terms of structure and operation, a simple mechanical transmission design is adopted, with the motor as the core driving source. Through the cooperation of the threaded shaft and the adjustment slider, precise lifting and flexible displacement of the box body are achieved, meeting diverse needs without complex operations, and greatly improving the usability; ② In terms of function expansion, the built-in mixing component can fully stir the liquid medicine evenly, providing professional cleaning and care for patients with limited mobility. At the same time, the design of the top plate hook and the sliding substrate has the function of a conventional medical device bracket, which can firmly hang the infusion device to meet the need of hanging water; ③ In terms of space utilization and user experience, the position of the device can be freely adjusted. It can be flexibly adjusted during use and moved to the end of the bed when not in use, effectively releasing the accompanying space and avoiding affecting daily activities such as family care. Considering both functionality and space compatibility, the practicality and user experience of the elderly care and rehabilitation nursing bed are significantly optimized.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0032] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0033] Embodiment 1: Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6, A nursing bed for the elderly and rehabilitation, comprising a bed body 1. A sliding base plate 2 is slidably connected to the side of the bed body 1. A support sleeve 3 is fixedly connected to the sliding base plate 2. The top of the support sleeve 3 is rotatably connected to a top plate 4. A number of hooks 5 are connected below the top plate 4. Conventional operations such as hanging water can be carried out through the hooks 5. An adjusting slider 6 is slidably arranged inside the support sleeve 3. A threaded shaft 7 is rotatably connected inside the support sleeve 3. The adjusting slider 6 is threadedly connected to the threaded shaft 7. A box body 8 is fixedly connected to the adjusting slider 6. A water outlet pipe 31 for discharging liquid is connected to the bottom of the box body 8. By connecting a hose and a valve, the liquid medicine inside the box body 8 can be controlled more conveniently. A mixing component 9 is arranged inside the box body 8. A driving component 10 for driving the threaded shaft 7 to rotate is arranged below the sliding base plate 2. The driving component 10 is also used to drive the mixing component 9 to mix. After the driving component 10 is started, it drives the threaded shaft 7 to rotate. The rotation direction determines whether the adjusting slider 6 moves upward or downward. The control of the rotation direction is a conventional technical means in this technical field. Pour water and liquid medicine into the box body 8. After the driving component 10 mixes them, it can be reversed, so that the adjusting slider 6 drives the box body 8 to move upward, facilitating the use of the mixed liquid inside the box body 8 to clean the patient.

[0034] A first notch 11 and a second notch 12 are formed on the support sleeve 3. The first notch 11 and the second notch 12 are arranged along the axial direction of the support sleeve 3. The second notch 12 is located above the first notch 11 and communicates with the first notch 11. The central angle corresponding to the second notch 12 is greater than the central angle of the first notch 11. When the driving component 10 rotates to drive the adjusting slider 6 to move upward, the adjusting slider 6 is restricted by the first notch 11 and slides upward. Then when the adjusting slider 6 moves to the position of the second notch 12, under the driving action of the threaded shaft 7, the adjusting slider 6 rotates and abuts against the edge position of the second notch 12. At this time, when the driving component 10 continues to move, the adjusting slider 6 can be made to move upward along the edge position of the second notch 12. When the thread of the threaded shaft 7 is disengaged from the adjusting slider 6, it no longer drives the adjusting slider 6 to move upward. Under the action of gravity, the adjusting slider 6 will abut against the thread outside the threaded shaft 7 to ensure that the driving component 10 can drive the adjusting slider 6 to move downward when it rotates in the reverse direction.

[0035] The first notch 11 faces away from the bed body 1. The central angle corresponding to the second notch 12 is 180°. When the adjusting slider 6 abuts against the edge position of the second notch 12, the box body 8 is located above the bed body 1. By setting the orientation of the first notch 11, the orientation of the box body 8 when it runs to the bottom can be limited. Facing away from the bed body 1 avoids occupying the space above the patient. And the second notch 12 is set to 180°. When the box body 8 moves upward, it will move above the bed body 1. At this time, the mixed liquid medicine inside the box body 8 can be used more conveniently, avoiding the situation of inconvenient cleaning caused by the deviation of the position of the box body 8.

[0036] Embodiment 2: This embodiment specifically discloses an implementation manner of a driving component 10. Please refer to Figure 2 and Figure 3 , the driving component 10 includes a motor 13. A horizontal driving shaft 14 is fixedly connected to the rotor of the motor 13. A first driving bevel gear 15 is fixedly connected to the outside of the horizontal driving shaft 14. A first driven bevel gear 16 is fixedly connected to the bottom of the threaded shaft 7. The first driving bevel gear 15 meshes with the first driven bevel gear 16. The rotation of the motor 13 can drive the threaded shaft 7 to rotate through the first driving bevel gear 15 and the first driven bevel gear 16, and the rotation direction is determined by the rotation direction of the motor 13.

[0037] A spring 17 is sleeved on the outside of the threaded shaft 7 and is located inside the support sleeve 3. When the adjusting slider 6 moves to the bottommost position and disengages from the threaded position of the threaded shaft 7, the adjusting slider 6 abuts against the thread of the threaded shaft 7 under the elastic force of the spring 17. When the motor 13 drives the box body 8 to move downward, it will directly drive the adjusting slider 6 to rotate and abut against the side of the first notch 11, and then slide downward.

[0038] Please refer to Figure 7 and Figure 8 , when the adjusting slider 6 is at the bottommost position, the mixing component 9 cooperates with the driving component 10 for mixing. The mixing component 9 includes a mixing shaft 18 rotatably connected to the box body 8. Mixing blades 19 are arranged on the outside of the mixing shaft 18. A square hole 20 is opened at the bottom of the mixing shaft 18. A transmission unit 21 for driving the mixing shaft 18 to rotate is arranged on the driving component 10. When the adjusting slider 6 moves to the lowermost position, there is no thread on the outside of the lower part of the threaded shaft 7. When the motor 13 drives the adjusting slider 6 to move to the bottommost position, the threaded shaft 7 cannot drive the adjusting slider 6 to move downward continuously. At this time, the spring 17 is in a compressed state, so that the adjusting slider 6 abuts against the thread on the outside of the threaded shaft 7, preventing the threaded shaft 7 from being unable to drive the adjusting slider 6 to move upward when the motor 13 rotates in reverse.

[0039] The driving unit 21 includes a second driving bevel gear 22 arranged at the top of the horizontal driving shaft 14. A square shaft 23 is rotatably connected to the sliding substrate 2. The square shaft 23 is matched with the square hole 20. A second driven bevel gear 24 is fixedly connected to the bottom of the square shaft 23. The second driven bevel gear 24 meshes with the second driving bevel gear 22. A one-way transmission mechanism 25 is arranged outside the horizontal driving shaft 14. The one-way transmission mechanism 25 is located between the first driving bevel gear 15 and the second driving bevel gear 22. When the motor 13 drives the adjusting slider 6 to move to the bottommost position, with the continuous rotation of the motor 13, it will drive the second driven bevel gear 24 to rotate through the second driving bevel gear 22, and drive the square shaft 23 to rotate. The square shaft 23 drives the mixing shaft 18 to rotate, and the mixing blades 19 can be used to mix the mixed liquid medicine inside the box body 8. The cooperation between the square shaft 23 and the square hole 20 can drive the mixing shaft 18 to rotate, or other prism shafts and matching holes can also be used to achieve power transmission. When the box body 8 moves to the bottommost position, it naturally cooperates with the square shaft 23 to realize stirring.

[0040] Please refer to Figure 9 , the one-way transmission mechanism 25 includes an outer sleeve ring 26 and an inner rotating ring 27. An inclined groove 28 is formed on the outer sleeve ring 26. A driving tooth 29 is rotatably connected to the inner rotating ring 27 through a torsion spring. The driving tooth 29 is matched with the inclined groove 28. The outer sleeve ring 26 and the inner rotating ring 27 are respectively connected to both ends of the horizontal driving shaft 14. The one-way transmission mechanism 25 enables the motor 13 to transmit power unidirectionally, that is, when the motor 13 drives the box body 8 to move downward, it will drive the square shaft 23 to rotate and match the mixing shaft 18 to realize mixing. On the contrary, when driving the box body 8 to move upward, the one-way transmission mechanism 25 disconnects the power and no longer mixes.

[0041] It is worth mentioning that during the process of the motor 13 driving the box body 8 to move downward, although the box body 8 will not continue to move downward after moving to the lowermost position, due to the cooperation of the threads, the box body 8 will vibrate up and down, and its stroke is the distance of one thread pitch. This vibration can cooperate with the mixing assembly 9 to greatly improve the mixing effect.

[0042] Embodiment 3: On the basis of the previous embodiment, the following technical content is further disclosed in this embodiment: A locking bolt 30 is connected to the sliding substrate 2. The locking bolt 30 is used to lock the relative position between the sliding substrate 2 and the bed body 1. The position of the sliding substrate 2 can be locked through the locking bolt 30, locked to the most convenient position during use, and when not in use, the locking bolt 30 is loosened, and the sliding substrate 2 can be moved to make the sliding substrate 2 away from the front side of the bed body 1 to avoid occupying space. This technical means is a conventional technical means in this technical field.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
