Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to the field of medical protective gear, and specifically refers to an adjustable semi-recumbent mattress structure. Background Art

[0002] Semi-recumbent position is one of the commonly used forced positions for the treatment of patients with fundus diseases. The requirement of semi-recumbent position is to raise the head of the bed so that the upper body and the lower body form an angle of 15 to 45 degrees. In clinical nursing work, it is found that when patients take the semi-recumbent position, due to the effect of gravity, the body often slides down, and some even slide to the supine position or fail to reach the required angle, and the treatment effect cannot be achieved. Nurses have to help semi-recumbent patients move to the head of the bed once every 1-2 hours, which consumes the nurses' time and physical strength. The sheets of semi-recumbent patients often slide down with the patient's body, causing wrinkles on the waist and back, and the patients The clothes worn by the patient will roll up due to the body sliding down, causing discomfort to the sheets and clothes under the waist, back and buttocks of the semi-recumbent patient, and prone to pressure injuries, or pain and discomfort in the sacrum and waist. How to reduce the discomfort brought to patients by the semi-recumbent position, especially the failure to meet the semi-recumbent position requirements, affecting the treatment effect and causing pressure injuries to the sacrum and coccyx skin, is currently a common concern of medical staff. The application of adjustable semi-recumbent mattresses in clinical practice has brought good news to patients. The hospital beds currently used by everyone are relatively simple and have some problems:

[0003] During the semi-recumbent position, the bed has no angle scale, which causes the patient to be too high or too low, failing to meet the requirements of the semi-recumbent position, thus affecting the treatment effect. The bed is hard and thin, causing pain and discomfort in the patient's waist, back, sacrum, and even sacrum pressure sores, which not only causes discomfort to the patient, but also causes adverse nursing events. Some patients cannot tolerate the discomfort caused by the semi-recumbent position and shake the bed flat without authorization, which delays the treatment effect and aggravates the condition.

[0050] Please refer to Figure 1 and 5 As shown, the adjustable semi-recumbent mattress structure of the present utility model, wherein the mattress structure includes:

[0051] Frame 1, on which a soft pad 2 is provided. The frame is divided into an upper frame and a lower frame. Among them, the upper frame is a positioning structure with adjustable angle, and the upper frame is provided with power for adjustment and support by a power device 3 arranged at the rear; several magic tapes 4 are provided on the soft pad 2 of the lower frame, and the magic tapes 4 are used for the patient to place a backrest 5 at a special part for blood return.

[0052] As a preferred embodiment of the present utility model, the power device 3 is composed of a connecting rod device, an angle positioning mechanism 6 and a power switching device 7. Among them, the connecting rod device includes a lifting rod 8 and a diagonal brace 9. The lifting rod 8 is arranged at the middle and lower position on the back of the upper frame and is in contact with the back of the upper frame. The diagonal braces 9 are respectively arranged on both sides of the lifting rod 8, and the bottom of the diagonal brace 9 is arranged on the angle positioning mechanism 6. The angle positioning mechanism 6 adjusts the position of the upper frame by controlling the angle of the connecting rod device. The power switching device 7 is used to provide power supply or manual adjustment for the mattress structure for angle adjustment. The angle positioning mechanism 6 and the power switching device 7 are connected by a lead screw 10.

[0053] As a preferred embodiment of the present utility model, the angle positioning mechanism 6 is composed of an angle ruler 6-1 and a positioning ball popping-up device arranged on the diagonal brace 9. The positioning ball popping-up device includes a positioning ball 6-2, a positioning socket 6-3 and a first spring 6-4. The positioning socket 6-3 is arranged at the corresponding positioning angle of the angle ruler 6-1. The first spring 6-4 is used to squeeze the positioning ball 6-2, and when the diagonal brace 9 moves to the corresponding angle, the positioning ball 6-2 pops into the positioning socket 6-3 to complete the positioning process of a special angle.

[0054] As a preferred embodiment of the present utility model, a rotating plug 7-1, a bearing box 7-2, bevel gears 7-3 and a motor 7-4 are arranged on the power switching device 7. At the connection position between the bearing box 7-2 and the bevel gears 7-3, a front linkage 7-5, a rear linkage 7-6, a middle shaft box 7-7, a positioning key 7-8 and a second spring 7-9 are also arranged. Among them, the middle shaft box 7-7 is arranged between the front linkage 7-5 and the rear linkage 7-6. The positioning key 7-8 is arranged in the middle shaft box 7-7, and the second spring 7-9 is arranged below the positioning key 7-8.

[0055] As a preferred embodiment of the present utility model, when the power switching device 7 is in the electric mode, the positioning key 7-8 is in the popped-up state, so that the bevel gear 7-3 drives the lead screw 10 to transmit power; when the power switching device 7 is in the manual mode, by pushing the rotating plug 7-1 to squeeze the positioning key 7-8, the second spring 7-9 contracts, and the positioning key 7-8 is retracted into the bevel gear 7-3. The hexagonal wrench head provided inside the rotating plug 7-1 engages with the hexagonal groove in the rear linkage 7-6. When the rotating plug 7-1 is rotated using a ratchet wrench 12, the connected rear linkage 7-6 drives the middle shaft box 7-7 and the front linkage 7-5, thereby driving the lead screw 10 to rotate, so as to adjust the lifting angle of the mattress structure.

[0056] As a preferred embodiment of the present utility model, a remote controller 11 is further provided on the upper frame. The remote controller 11 is used to control the motor 7-4 to start and enable the user to adjust the angle.

[0057] As a preferred embodiment of the present utility model, the frame 1 includes a basic frame part 1-1 and a bottom frame part 1-2 corresponding to the upper frame. The bottom frame part 1-2 is used to provide frame support for the power device 3.

[0058] In practical applications, please refer to Figures 2 to 4 As shown, the power device mainly consists of a power switching device 7 and an angle positioning mechanism 6. The purpose of the power switching device 7 is to manually switch to the manual mode when there is no power supply. In the electric mode, the positioning key 7-8 is in the popped-up state, so that the bevel gear 7-3 can normally drive the lead screw 10 to transmit power, and the connecting rod device composed of the lifting rod 8 and the diagonal strut 9 is used to achieve the lifting purpose. However, when in a state without a stable power supply, it is necessary to switch to the manual state. As shown in the figure, when the rotating plug 7-1 is pushed, under the thrust, the positioning key 7-8 will be squeezed, causing the spring below to contract, and thus the positioning key 7-8 will be retracted into the bevel gear 7-3. In this way, the middle shaft box 7-7 has no components engaging with the inside of the bevel gear 7-3 due to the retraction of the positioning key 7-8, forming a free rotation state. At the same time, there is a hexagonal wrench head inside the rotating plug 7-1, which engages with the hexagonal groove in the rear linkage 7-6. When the rotating plug 7-1 is rotated using a ratchet wrench 12, the connected rear linkage 7-6 drives the middle shaft box 7-7 and the front linkage 7-5, thereby driving the lead screw 10 to rotate and affecting the lifting of the mattress. When there is a stable power supply clinically, only need to pull out the rotating plug 7-1, and the spring of the middle shaft box 7-7 will pop up the positioning key 7-8, so that the bevel gear 7-3 can work normally.

[0059] The frequently used semi-recumbent angles for semi-recumbent patients are 15°, 30° and 45°. Therefore, we designed an angle positioning mechanism 6. A steel angle ruler 6-1 is used, and positioning pits 6-3 are made at its positioning angles. A positioning ball bouncing device (composed of a positioning ball 6-2, a positioning pit 6-3 and a spring) is installed on the diagonal brace 9. When the diagonal brace rotates to the corresponding angle, the positioning ball 6-2 will bounce into the positioning pit 6-3, and there will be an obvious jamming, so as to achieve the purpose of special angle positioning; when the diagonal brace 9 is rotated continuously, the positioning ball 6-2 will be squeezed into the spring outer sleeve due to the contraction of the spring, and the sliding of the positioning ball 6-2 will not generate much resistance. When the next positioning pit 6-3 is encountered during operation, the positioning ball 6-2 pops out, and there will be an obvious jamming again, so as to achieve the purpose of special angle positioning.

[0060] Please refer to Figure 5 As shown, a plurality of magic tapes 4 are fixed on the patient's mattress, mainly distributed at the patient's knees and hips. The backrest 5 can be placed on the bed at will and can be effectively adsorbed on the magic tape 4 no matter which position it is placed on. In this way, the patient can use the backrest 5, and the backrest 5 will not slide due to friction and affect the patient's use.

[0061] The adjustable semi-recumbent mattress structure of the present utility model is adopted, and an integrated flashlight design is used, which can conveniently switch the power mode and greatly improve its application range. At the same time, according to the clinical use situation, angle positioning devices of 15°, 30°, 45°, 50°, 70° and 80° are added, and the commonly used lying posture angles can be accurately controlled. At the same time, according to the clinical situation, a magic tape-fixed backrest is designed to ensure that cushions can be added to the knee joint, hip joint and back according to the actual situation to improve the comfort of the patient.

[0062] In this specification, the present utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and transformations can still be made without departing from the spirit and scope of the present utility model. Therefore, the specification and drawings should be regarded as illustrative rather than restrictive.
