Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more specifically, to an emergency support device for patients with severe respiratory illness. Background Art

[0002] During the emergency transfer of critically ill respiratory patients, medical beds must take into account the space limitations of the ambulance and the convenience of patient transfer. Traditional emergency beds mostly use fixed running wheels or independent lifting mechanisms, which have problems such as complex structure and insufficient storage height, resulting in low space utilization when loading the ambulance. In addition, patients often need to adjust their body position during transfer (such as sitting up, turning over), and existing equipment mostly achieves this through manual rockers or separate pads, which has low operating efficiency and is prone to secondary injuries. Some beds with baffles have the defects of protruding deployment mechanisms and inconvenient storage, which are prone to collisions during emergency transfers.

[0003] The Chinese invention patent with publication number CN113730132A discloses a multifunctional cardiac intensive care nursing bed, which adjusts the height of the bed board by setting a lifting mechanism between the base frame and the bed board. However, since the lifting is achieved by using a threaded rod and a threaded sleeve, the lowest height of the bed must be higher than the height of the threaded sleeve, which makes it impossible to use it with an ambulance.

[0004] The Chinese invention patent with publication number CN108175604A discloses a turning and transfer bed, which includes an armrest mounting frame fixed on a bed frame, a base shaft is arranged on the armrest mounting frame, and a first armrest connecting rod is arranged on the base shaft through a bearing sleeve. Since the first armrest connecting rod can only rotate relative to the base shaft, the first armrest connecting rod and the structure arranged thereon cannot be stored, which affects the use range of the transfer bed.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] like Figure 1 , Figure 2 As shown, a first aid support device for patients with severe respiratory diseases includes a bed frame 1 and a bed board 2 arranged on the bed frame 1. A nursing pad 7 capable of absorbing liquid is placed on the bed board 2 to improve the comfort of the patient when using it. The nursing pad 7 can use the nursing pad body structure disclosed in the utility model patent with publication number CN204092337U. A set of lifting mechanisms are arranged on both the front and rear sides of the bed frame 1, and each set of lifting mechanisms includes two unfolding wheel mechanisms 3 arranged symmetrically on the left and right; the state of the first aid support device can be switched by the lifting mechanism. When the unfolding wheel mechanism 3 is folded, it is convenient to enter the ambulance; when the unfolding wheel mechanism 3 is unfolded, it is convenient to move to transfer the patient.

[0024] The wheel-unfolding mechanism 3 includes a connecting rod Ⅰ31, a connecting rod Ⅱ32, a connecting rod Ⅲ33 and a connecting rod Ⅳ34. A linear slide 39 is provided on the bed frame 1. A first slider 35 is slidably provided in the linear slide 39. One end of the connecting rod Ⅱ32 is hinged on the first slider 35. One end of the connecting rod Ⅰ31 is hinged on the bed frame 1. The other end of the connecting rod Ⅰ31 is hinged to the connecting rod Ⅱ32. When the first slider 35 moves horizontally in the linear slide 39, the connecting rod Ⅱ32 is driven to rotate. A sliding arrangement is provided on the connecting rod Ⅱ32 along the length direction. There is a mounting rod 36, and the connecting rod IV34 adopts a telescopic rod. One end of the connecting rod IV34 is hinged to the mounting rod 36, and the other end of the connecting rod IV34 is hinged to the bed frame 1; one end of the connecting rod III33 is hinged to the first slider 35, and the other end of the connecting rod III33 is hinged to the connecting rod IV34; when the first slider 35 moves, the connecting rod IV34 is driven to rotate through the connecting rod III33, and when the connecting rod IV34 rotates, it drives the mounting rod 36 to slide relative to the connecting rod II32 to achieve height adjustment. The lower end of the mounting rod 36 is provided with a walking wheel 37.

[0025] The wheel-unfolding mechanism 3 drives the connecting rod II 32 and the connecting rod III 33 to move simultaneously through the first slider 35, so as to adjust the height of the running wheel 37, and reduce the length of a single connecting rod, so as to facilitate storage. When the wheel-unfolding mechanism 3 is folded, the height dimension is small, so as to facilitate entering the ambulance; and in the folded state, the running wheel 37 still has the function of running.

[0026] The first slider 35 is connected to a first driving mechanism, and the first slider 35 is driven to move by the first driving mechanism. Specifically, the first driving mechanism includes a driving rod 38 and a linear motor Ⅰ4. The driving rod 38 is fixedly connected between the two first sliders 35 of each lifting mechanism. The linear motor Ⅰ4 is arranged between the driving rod 38 and the bed frame 1. The linear motor Ⅰ4 drives the driving rod 38 to move, thereby driving the first sliders 35 on both sides to move horizontally along the bed frame 1 at the same time.

[0027] In order to help patients in need to sit up, the bed board 2 includes a first bed board 21 and a second bed board 22. Correspondingly, two nursing pads 7 are provided. The two nursing pads 7 are respectively provided on the first bed board 21 and the second bed board 22. The two nursing pads 7 are staggered at their ends close to each other. The first bed board 21 is fixedly connected to the bed frame 1, and a back support structure 5 is provided between the second bed board 22 and the bed frame 1. Preferably, as Figure 5 As shown, the back support structure 5 includes a connecting rod V53 and a third slider 55, one end of the connecting rod V53 is hinged to the second bed board 22, a guide rail 54 is arranged on the bed frame 1, the other end of the connecting rod V53 is hinged to the third slider 55, and the third slider 55 is slidably matched with the guide rail 54; the third slider 55 is connected to a second driving mechanism 6 that drives it to move along the guide rail 54. In this embodiment, the second driving mechanism 6 adopts a linear motor II, and the linear motor II directly or indirectly drives the third slider 55 to move, and then the second bed board 22 is lifted up through the connecting rod V53.

[0028] Since the patient's back will move upward relative to the second bed board 22 during the lifting process, in order to reduce the relative movement, such as Figure 3 , Figure 4 As shown, the bed frame 1 is provided with an arc-shaped slide groove 51, and the lower end of the second bed board 22 is fixedly provided with a second slider 52, which is an arc-shaped structure and cooperates with the arc-shaped slide groove 51. When the second bed board 22 is lifted up, the second slider 52 moves relative to the arc-shaped slide groove 51, so that the second bed board 22 can move upward, partially offsetting the relative movement between the patient's back and the second bed board 22, and improving the patient's comfort.

[0029] Preferably, a roller group 56 is provided on the upper arc surface and / or the lower arc of the second slider 52, and the roller group 56 includes at least three rollers, and the rolling surfaces of the rollers are in contact with the arc-shaped slide groove 51. The rollers reduce the friction between the second slider 52 and the arc-shaped slide groove 51.

[0030] like Figure 7 As shown, in order to help patients in need to turn over, a sink 23 is provided on the same side of the first bed board 21 and the second bed board 22. A support airbag 24 is provided in the sink 23, and the support airbag 24 is connected to an inflator. When the patient needs to turn over, the support airbag 24 is inflated to assist the patient in turning over.

[0031] To prevent the patient from falling from the support device, Figures 7 to 9 As shown, baffles are provided on both sides of the bed frame 1. Specifically, a mounting plate 111 is fixedly provided inside the bed frame 1, a guide groove 112 is provided on the mounting plate 111, a fourth slider 15 is slidably provided inside the guide groove 112, a connecting rod 16 is hinged on the fourth slider 15, and a baffle 17 is hinged on the end of the connecting rod 16 away from the fourth slider 15; grooves for the baffle 17 to enter and exit are provided on both sides of the bed frame 1. When the baffle is not needed, the baffle 17 and the connecting rod 16 can be stored in the groove. The guide groove 112 can limit the maximum stroke of the fourth slider 15 to prevent the fourth slider 15 from escaping from the guide groove 112. A vertical socket 18 for inserting the baffle 17 is provided on the bed frame 1, and a boss 110 for limiting the maximum rotation angle of the baffle 17 is provided on the connecting rod 16. When the baffle is needed, pull out the baffle 17 and rotate it to fit with the boss 110 of the connecting rod 16. At this time, the baffle 17 is perpendicular to the connecting rod 16, and the lower end of the baffle 17 is inserted into the vertical insertion hole 18 to ensure the reliability of the baffle 17. A pressing plate 19 is provided on the side of the first bed board 21. The pressing plate 19 is hinged to the first bed board 21. When the pressing plate 19 is under pressure and is parallel to the first bed board 21, the pressing plate 19 restricts the connecting rod 16 from rotating upward, preventing the baffle 17 from being separated from the vertical insertion hole 18.

[0032] The travel wheel 37 is provided with a locking mechanism.

[0033] Embodiment 2:

[0034] A first aid support device for patients with severe respiratory diseases, based on Example 1, the first driving mechanism can be replaced by the following structure: like Figure 6 As shown, the first driving mechanism includes a sprocket 11 and a stepper motor 13, and a driving rod 38 is fixedly connected between the two first sliders 35 of each lifting mechanism. The front and rear ends of the bed frame 1 are rotatably provided with sprockets 11, and the two sprockets 11 are connected by a chain 12. The two driving rods 38 are fixedly connected to the two sides of the chain 12 respectively; one of the sprockets 11 is connected to the stepper motor 13. When the stepper motor 13 drives one of the sprockets 11 to rotate, the two driving rods 38 are simultaneously driven to move in the opposite direction through the chain 12, thereby driving the four first sliders 35 to move, thereby realizing the control of the wheel unfolding mechanism 3.
