Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, specifically to an intelligent support armrest structure for a nursing bed. Background Technology

[0002] With the increasing aging of my country's population, the health and quality of life of the elderly have become the focus of social attention. Currently, there are 35 million elderly and disabled people in my country who are completely disabled and whose main mode of living is bedridden and require full-time care. In response to this emerging market demand, many companies at home and abroad have launched intelligent nursing bed products with their own unique features.

[0003] While many nursing beds on the market are touted as "intelligent," their core control mechanisms still rely on traditional electromechanical control methods. A typical example is using PLC control technology to manipulate the bed's form to a limited extent, providing some auxiliary functions for patients, such as assisting with adjusting position and raising / lowering the bed height. However, when focusing on the crucial and private daily care aspect of urination and defecation, many inconveniences become apparent. Although the nursing bed has some transformation capabilities, due to its design limitations, patients often find it difficult to stably align themselves with the bedpan, especially those with lower limb disabilities or extreme weakness, who are almost completely unable to perform this action independently. This inevitably leads to caregivers needing to manually assist patients in ensuring they can urinate and defecate smoothly. This process not only increases the workload and working hours of caregivers but may also cause accidents due to operational difficulties or patient discomfort, such as patients slipping or caregivers spraining their backs. Therefore, we propose an intelligent support armrest structure for nursing beds. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an intelligent support armrest structure for a nursing bed, comprising:

[0005] Deflection assembly, installed on the lower end face of the bed board of the nursing bed;

[0006] An electric actuator is hinged to a deflection assembly, which enables the deflection of the electric actuator. The output end of the electric actuator is hinged to a first mounting base, and a second mounting base can be detachably mounted on the first mounting base.

[0007] Two supporting handrails are connected by a mounting plate between the ends of the two supporting handrails and the second mounting base.

[0008] In some embodiments, the deflection assembly includes a stepper motor and a deflection frame, the output end of the stepper motor is mounted with a connecting shaft, the top end of the deflection frame is connected with a connecting protrusion, and the connecting protrusion is connected to the connecting shaft.

[0009] In some embodiments, a pressure sensor is embedded at one end of the deflection frame near the support armrest.

[0010] In some embodiments, the first mounting base has a groove for receiving the end of the second mounting base, and a guide groove is provided on the inner side wall of the groove. Guide strips that are inserted into and cooperate with the guide groove are fixed on both sides of the second mounting base.

[0011] In some embodiments, the outer wall of the second mounting base is provided with a groove, and a fastening screw that can be screwed into the first mounting base is screwed into the inside of the groove.

[0012] In some embodiments, the support armrest is integrally formed from two sections, with the section furthest from the mounting plate tilting upward to form a blocking portion.

[0013] In some embodiments, the support armrest is covered with a soft sleeve.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. The device is equipped with a deflection component and support handrails. The deflection component allows the electric push rod to move closer to or further away from the bed board. When the electric push rod reaches the position closest to the bed board, the support handrail is extended by the electric push rod to support and fix the patient's body. The patient can sit up to urinate or defecate on their own without the need for assistance from nursing staff. This reduces the labor intensity and working hours of nursing staff and avoids the disadvantages of patients slipping and nursing staff twisting their waists.

[0016] 2. After the deflection frame deflects to the bed board, the pressure sensor senses the pressure and can quickly transmit the signal to the controller. The controller then stops the stepper motor and starts the electric push rod in time to achieve rapid adjustment, effectively preventing mechanical failures or damage to the bed structure that may be caused by excessive rotation of the deflection frame.

[0017] 3. When installing the second mounting base, the end of the second mounting base can be inserted into the groove and the guide strip can be embedded in the guide groove to guide the installation of the second mounting base and avoid misalignment. Attached Figure Description

[0025] 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.

[0026] Example 1

[0027] Please see Figures 1-6 As shown, this utility model provides a technical solution: an intelligent support armrest structure for a nursing bed, including a deflection component 1, an electric push rod 2, and two support armrests 6. The nursing bed is equipped with a controller, and the electric push rod 2 is electrically connected to the controller. The deflection component 1 is installed on the lower end surface of the bed board of the nursing bed, and the electric push rod 2 is hinged to the deflection component 1. The deflection component 1 realizes the deflection of the electric push rod 2. A first mounting seat 3 is hinged to the output end of the electric push rod 2, and a second mounting seat 4 is detachably installed on the first mounting seat 3. The ends of the two support armrests 6 are connected to the second mounting seat 4 through a mounting plate 5. The support armrest 6 is integrally formed from two sections, and the section away from the mounting plate 5 is inclined upward to form a blocking part. When the support armrest 6 supports the bedridden patient from under the armpit, the head of the support armrest 6 is inclined upward, allowing the patient to urinate and defecate in a relatively safe state, greatly reducing the risk of accidental slippage and injury.

[0028] See Figure 2 and Figure 3As shown, the deflection assembly 1 includes a stepper motor 101 and a deflection frame 103. A connecting shaft 102 is installed at the output end of the stepper motor 101. A connecting protrusion 104 is connected to the top of the deflection frame 103. The connecting protrusion 104 is connected to the connecting shaft 102. When the stepper motor 101 is started, the connecting shaft 102 is rotated by the stepper motor 101, which in turn causes the deflection frame 103 with the connecting protrusion 104 to deflect, so that the electric push rod 2 on the deflection frame 103 moves closer to or away from the bed board. When the electric push rod 2 reaches the state closest to the bed board (the end of the deflection frame 103 deflects to abut against the bed board), the support armrest 6 is pushed out by the electric push rod 2 to support and fix the patient's body. The patient can sit up to urinate or defecate on their own without the help of nursing staff, which reduces the labor intensity and working hours of nursing staff and avoids the disadvantages such as the patient slipping and the nursing staff twisting their waist.

[0029] A pressure sensor 8 is embedded at one end of the deflection frame 103 near the support armrest 6. After the end of the deflection frame 103 deflects to abut against the bed board, the pressure sensor 8 senses the pressure and transmits the signal to the controller. The controller then stops the stepper motor 101 in time and starts the electric push rod 2.

[0030] See Figure 4 and Figure 5 As shown, the first mounting base 3 has a groove for accommodating the end of the second mounting base 4. A guide groove 11 is provided on the inner side wall of the groove. Guide strips 9 are fixed on both sides of the second mounting base 4 and are inserted into the guide groove 11. A groove 12 is provided on the outer wall of the second mounting base 4. A fastening screw 10 that can be screwed into the first mounting base 3 is screwed into the groove 12.

[0031] The first mounting base 3 and the second mounting base 4, which are detachably connected, allow for easy replacement of the support armrest 6 on the second mounting base 4 when needed. When installing the second mounting base 4, the end of the second mounting base 4 can be inserted into the groove, and the guide strip 9 can be embedded in the guide groove 11 to guide the installation of the second mounting base 4 and prevent misalignment. This improves the accuracy and efficiency of the installation of the second mounting base 4. Then, it can be tightened using the fastening screws 10 located in the groove 12. In addition, other screws can be provided on the side of the first mounting base 3 for reinforcement, allowing for tightening from two perpendicular directions to ensure stability.

[0032] Example 2

[0033] Please see Figure 2 and Figure 3 As shown, this embodiment is an extension of embodiment 1. Specifically, a soft sleeve 7 is fitted over the outside of the supporting handrail 6.

[0034] The aforementioned soft sleeve 7 is made of high-quality, soft, and elastic material. This special material has excellent cushioning properties. When a bedridden patient needs to urinate or defecate, and the support armrest 6 bears the patient's body weight and applies force under the armpit, the soft sleeve 7 can effectively distribute the pressure and prevent excessive local pressure concentration. Compared to the situation without the protection of the soft sleeve 7, it greatly reduces the pain caused by compression, allowing the patient to experience a more comfortable experience while being supported. At the same time, the surface of the soft sleeve 7 has also undergone special anti-slip treatment, ensuring stable contact between the support armrest 6 and the patient's armpit even when the patient makes some slight struggles or movements, preventing slippage or displacement, further ensuring the patient's safety and comfort when urinating or defecating, and providing a more humane assistance for the entire nursing process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
