Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable medical bed and medical rescue system. Background Technology

[0002] In the modern medical field, medical beds, as fundamental and crucial medical equipment, directly affect the efficiency and safety of patient transfer, nursing, and treatment through their diverse functions and practicality. Currently, most medical beds on the market adopt a vertical lifting design. This design mainly uses an electric or hydraulic drive system to achieve vertical adjustment of the bed height, meeting the needs of patients for daily bed rest and getting up, as well as basic nursing operations for medical staff.

[0003] However, in real-world medical settings, vertically lifting medical beds have significant limitations. For example, when docking the medical bed with an ambulance, the height difference between the ambulance compartment and the hospital floor, coupled with the fixed interior layout of the ambulance, makes it difficult for the vertically lifting medical bed to connect smoothly with the ambulance stretcher. Medical staff often need to use ramps or manually lift the patient for transport, which is not only cumbersome and inefficient but also highly susceptible to secondary injury due to improper handling, increasing patient suffering and treatment risks.

[0004] Furthermore, with the diversification of medical scenarios, such as community healthcare and outdoor emergency rescue, higher demands are placed on the adaptability of medical beds. Medical beds that are fixed in a vertical lifting configuration cannot flexibly adjust their posture according to different terrains and spatial conditions, severely limiting their scope of use and making it difficult to meet diverse medical needs.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0024] Example 1:

[0025] See Figure 1 As shown, this utility model provides an adjustable medical bed, comprising: a base plate 100 and a bed board 500, wherein the base plate 100 and the bed board 500 are spaced apart in the vertical direction; a horizontal drive assembly 200, wherein the horizontal drive assembly 200 includes a first slide 220 that can reciprocate along a first direction X, the first slide 220 being slidably disposed on the base plate 100; and a connecting rod assembly 300, wherein the connecting rod assembly 300 includes a fixed support leg 310 and a telescopic support leg 320 arranged in a cross configuration, one end of the fixed support leg 310 being rotatably connected to the first slide 220, and the other end being rotatably connected to the bed board 500, and being slidably fitted against the bed board 500. The telescopic support leg 320 includes a sleeve 321 and a telescopic rod 322. One end of the sleeve 321 is rotatably connected to the base plate 100, and the sleeve 321 is rotatably connected to the middle of the fixed support leg 310. The telescopic rod 322 is disposed inside the sleeve 321 and is rotatably connected to the bed board 500. The flip drive assembly 400 includes a flip driver 420 and a push rod 430. The flip driver 420 is rotatably connected to the base plate 100. One end of the push rod 430 is connected to the flip driver 420, and the other end is connected to one side of the bed board 500 to drive the bed board 500 to flip.

[0026] Furthermore, the adjustable medical bed described in this embodiment can be raised and lowered or the bed board 500 can be flipped according to actual usage needs. Specifically, it includes, for example... Figure 2The first state shown is characterized by a horizontal surface of the bed board 500, which allows for lifting and lowering via the cooperation of the horizontal drive assembly 200 and the linkage assembly 300. Furthermore, it also includes... Figure 3 The second state shown is in which the surface of the bed board 500 is tilted at an angle to the horizontal direction, and the tilt of the bed board 500 can be adjusted by the flip drive assembly 400 according to actual needs.

[0027] The adjustable medical bed described in this embodiment achieves the effect of converting horizontal driving force into stable lifting and lowering drive by installing a horizontal drive assembly 200 and a connecting rod assembly 300 between the base plate 100 and the bed board 500. Simultaneously, the addition of a flipping drive assembly 400 further enables the bed board 500 to flip. Based on the above structural design, the bed board 500 in this application can freely rise and fall relative to the base plate 100, and its tilt angle can be adjusted to facilitate docking with other rescue equipment or to be applicable to more special scenarios. Compared with conventional medical beds at present, this application has advantages such as flexible use, wide applicability, strong controllability, and ease of operation. It not only facilitates patient movement and improves patient comfort, but also meets the diverse needs of current medical scenarios.

[0028] It should be noted that, for ease of description, in this embodiment, the length direction of the adjustable medical bed is defined as the first direction X, the width direction of the adjustable medical bed is defined as the second direction Y, and the height direction of the adjustable medical bed is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0029] Specifically, in this embodiment, the base plate 100 serves as the basic support structure of the medical bed, directly contacting the ground and providing stable support for the entire bed. The bed board 500 is used to support the patient and is the platform directly used by the patient. The two are spaced apart along the vertical direction, providing space for the installation and operation of the intermediate drive components and connecting rod components 300.

[0030] In this embodiment, the fixed support leg 310 and the telescopic support leg 320 are arranged in a cross manner, and the fixed support leg 310 and the telescopic support leg 320 are connected by a rotating connector 330, thereby forming a stable support structure. The rotating connector 330 is preferably a screw. The middle parts of the fixed support leg 310 and the telescopic support leg 320 are both sleeved on the shank of the screw and can rotate relative to the screw.

[0031] To further improve the stability of this adjustable medical bed, the linkage assembly 300 in this embodiment includes two fixed legs 310 and two telescopic legs 320 symmetrically arranged along the second direction Y, thereby forming two symmetrically arranged scissor-like structures in the second direction Y. Correspondingly, the base plate 100 in this embodiment is provided with two first horizontal modules 110 for sliding connection of the two fixed legs 310. The two fixed legs 310 are respectively connected to both ends of the first slide 220 to ensure its movement stability. Correspondingly, the bottom surface of the bed board 500 in this embodiment is provided with two second horizontal modules 510, and the horizontal drive assembly 200 also includes a second slide 230. The projection of the second horizontal module 510 in the vertical direction extends along the first direction X. The second slide 230 is slidably connected to the second horizontal module 510, and the fixed legs 310 are rotatably connected to the second slide 230. Based on this, the two first horizontal modules 110 provided on the base plate 100 provide stable sliding tracks for the two fixed outriggers 310. When the fixed outriggers 310 are connected to both ends of the first carriage 220 and slide along the first horizontal modules 110, the guiding effect of the horizontal modules can effectively limit the offset and swaying of the fixed outriggers 310 during movement, making the movement of the fixed outriggers 310 more stable and precise. This not only ensures the stability of the connected linkage assembly 300 and the bed board 500 during horizontal displacement, but also avoids discomfort and potential risks to patients caused by unstable movement. For example, when the medical bed is brought close to the ambulance for docking, stable horizontal movement can ensure that the bed board 500 is precisely aligned with the ambulance stretcher, improving the safety of transport.

[0032] The cooperation between the two second horizontal modules 510 on the bed board 500 and the second slide 230 further enhances the stability of the bed structure. The second slide 230 slides along the second horizontal module 510, providing a stable support point for the rotational connection of the fixed support leg 310. During tilting or flipping operations of the bed board 500, the stable cooperation between the second slide 230 and the second horizontal module 510 disperses the force borne by the fixed support leg 310, preventing structural deformation or shaking due to uneven force distribution. This ensures the bed remains stable even under complex operations, providing a safe and reliable environment for patients. Simultaneously, the design of the double horizontal modules and double slides structurally increases the connection points and support structures between the fixed support leg 310 and the bed, resulting in a more uniform force distribution throughout the bed.

[0033] In this embodiment, the horizontal drive assembly 200 further includes a horizontal driver 210. A first horizontal module 110 is provided on the base plate 100. All horizontal drivers 210 are connected to the base plate 100. The first horizontal module 110 extends along a first direction X. A first carriage 220 is slidably connected to the first horizontal module 110. The horizontal driver 210 is located at one end of the first horizontal module 110, and its working end is connected to the first carriage 220 to drive the first carriage 220 to move along the first horizontal module 110. Specifically, the horizontal drive assembly 200 also includes a guide rod 240 and a fixing block 250. The fixing block 250 is disposed on the base plate 100 and located at one end of the first horizontal module 110. One end of the guide rod 240 is connected to the fixing block 250, and the other end extends along the first direction X and passes through the first carriage 220. Preferably, the horizontal driver 210 is a horizontal motor. Compared to traditional vertical lifting medical beds, the horizontal drive function greatly improves the flexibility and applicability of the bed. When docking with an ambulance, the medical bed can be precisely adjusted in position by moving the first carriage 220, thereby reducing the operational difficulty during patient transfer and improving transfer efficiency.

[0034] See Figure 3 As shown, the flip drive assembly 400 is disposed between the two telescopic support legs 320. The flip drive 420 is rotatably connected to the base plate 100, providing power for the flipping operation. One end of the push rod 430 is connected to the flip drive 420, and the other end is connected to one side of the bed board 500. When the flip drive 420 is working, the push rod 430 pushes one side of the bed board 500, causing the bed board 500 to flip around the rotation axis, thereby changing the posture of the bed board 500. Specifically, the flip drive assembly 400 also includes a connecting block 410. The flip drive 420 is rotatably connected to the connecting block 410 to realize the connection between the flip drive 420 and the base plate 100. The upper surface of the base plate 100 and the lower surface of the bed board 500 are both connected to the connecting frame 600. The sleeve 321 is rotatably connected to the connecting frame 600 on the base plate 100, and the telescopic rod 322 is rotatably connected to the connecting frame 600 on the bed board 500. Specifically, in this embodiment, the flipping driver 420 is preferably a linear motor. In different implementations, it can also be configured as other structures or components with a pushing drive function according to actual usage requirements. This utility model does not impose specific limitations on this.

[0035] In this embodiment, the adjustable medical bed further includes a control mechanism, and the horizontal drive component 200 and the tilt drive component 400 are respectively connected to the control mechanism. During actual production and processing, operators can adjust the above structure in real time through the control mechanism, thereby improving the flexibility of the medical bed's use. Parameters can also be preset through the control mechanism, thereby improving the automation level of the medical bed.

[0036] Example 2:

[0037] This embodiment also provides a medical rescue system, which includes the adjustable medical bed described in Embodiment 1.

[0038] In summary, the adjustable medical bed and medical rescue system described in this application, with its various structures working together, expands the functionality of the medical bed from multiple dimensions, effectively solves the limitations of traditional vertical lifting medical beds in practical applications, and has significant advantages in patient transfer, nursing, and rehabilitation training, greatly improving the practicality and safety of the medical bed and meeting the diverse needs of the modern medical industry.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
