DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, a nursing mattress for sensing and monitoring when leaving the bed comprises a filling layer 6, a breathable fabric layer 7, and a wrapping layer. The filling layer 6 and the breathable fabric layer 7 are wrapped in the wrapping layer. A pressure sensor 2 and a blast pipe 3 are arranged between the filling layer 6 and the breathable fabric layer 7. The blast pipe 3 is provided with a plurality of air outlet holes 32. One end of the blast pipe 3 is connected to a foot-operated blowing device 5 through a connecting pipe 4.

[0025] When a human body lies on the nursing mattress, the area where the air blowing tube 3 is located corresponds to the back of the human body.

[0026] In the utility model, the pressure sensor 2 is connected to the control device. The control device can be placed at the head of the bed or near the bed. When the patient lies on the nursing mattress, the pressure sensor 2 can detect the patient's pressure signal. When the detected pressure value is greater than the set threshold, it indicates that the patient is on the bed; if the patient accidentally rolls off the bed, the pressure value detected by the pressure sensor 2 is very small, almost zero, and less than the set threshold. At this time, the control device will sound an alarm to remind the surrounding medical staff so that the patient can get quick help and reduce the damage to the patient. The area where the blast tube 3 is located corresponds to the back of the human body. The blast tube 3 set between the filling layer 6 and the breathable fabric layer 7 can improve the air flow between the patient's back and the mattress; the surrounding accompanying personnel can inflate the blast tube 3 by stepping on the foot-operated blast device 5, and the air is discharged through the air outlet 32 ​​on the blast tube 3. The discharged air will pass through the breathable fabric layer 7 with good air permeability and enter the gap between the patient's back and the mattress, thereby improving the air flow of the patient's back, cooling the patient's back, reducing the stuffiness of the back, and improving the patient's comfort.

[0027] Wherein, the filling layer 6 is made of high-density sponge material. The breathable fabric layer 7 is made of highly breathable fabric.

[0028] Two pressure sensors 2 are arranged between the filling layer 6 and the breathable fabric layer 7. When a person lies on the nursing mattress, the two pressure sensors 2 correspond to the back and buttocks of the person, respectively. When the pressure value detected by any one of the two pressure sensors 2 is greater than the set threshold, the patient is still on the bed, and the control device does not sound an alarm; only when the pressure values ​​detected by the two pressure sensors 2 are both less than the set threshold, the control device will sound an alarm; the above method can effectively reduce the probability of false alarms.

[0029] In this embodiment, the pressure sensor 2 is a thin film pressure sensor. The thin film pressure sensor is a prior art, has a relatively thin thickness, is easy to be arranged in the mattress, and does not affect the softness and comfort of the mattress.

[0030] The blast pipe 3 includes a plurality of parallel straight pipe sections 31, the ends of two adjacent straight pipe sections 31 are connected by arc pipe sections 33, and the air outlet holes 32 are arranged on the straight pipe sections 31. One end of the blast pipe 3 is a closed end, and the other end is an open end, and the open end is connected to the connecting pipe 4. The blast pipe 3 is a serpentine tubular structure as a whole.

[0031] The pedal inflating device 5 comprises a piston cylinder 51, in which a piston 53 is arranged, a spring 55 is arranged between the piston 53 and the bottom of the piston cylinder 51, and an air chamber 54 is formed between the piston 53 and the bottom of the piston cylinder 51; the upper end of the piston 53 is connected with a movable rod 56, which passes through the upper end of the piston cylinder 51, and a pedal 57 is arranged on the upper end of the movable rod 56; the upper end of the piston cylinder 51 is provided with a first through hole 52; the piston 53 is provided with a second through hole 58, in which a guide rod 59 is fixedly arranged, and a connecting rib plate 510 is arranged between the upper end of the guide rod 59 and the inner wall of the second through hole 58. The guide rod 59 is slidably connected with a movable valve plate 511, and the center of the movable valve plate 511 is provided with a center hole, and the guide rod 59 passes through the center hole on the movable valve plate 511. The lower end of the guide rod 59 is a restraining end, and the diameter of the restraining end is larger than the diameter of the center hole to ensure that the movable valve plate 511 will not separate from the guide rod 59. The movable valve plate 511 is located below the second through hole 58. One end of the connecting pipe 4 is connected to the air cavity 54. The diameter of the movable valve plate 511 is larger than the diameter of the second through hole 58. A rubber ring 512 is provided at the edge of the upper surface of the movable valve plate 511.

[0032] When the pedal 57 is pressed, the piston 53 moves downward. At this time, the pressure in the air cavity 54 increases, and the movable valve plate 511 moves upward relative to the piston 53 and blocks the second through hole 58. As the piston 53 moves downward, the air in the air cavity 54 will be pressed out of the air cavity 54 and filled into the blast pipe 3 through the connecting pipe 4; when the pedal 57 is released, the piston 53 and the pedal 57 move upward and reset under the action of the spring 55. During the upward movement of the piston 53, the movable valve plate moves away from the piston 53, and a gap is formed between the movable valve plate and the second through hole 58. The outside air can be sucked into the air cavity 54 through the first through hole 52 and the second through hole 58.

[0033] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
