[0043] See also Figure 1 , Figure 4 and Figure 5 In some embodiments, a first restraint belt 120 and a second restraint belt 121 are further included, one end of the first restraint belt 120 and one end of the second restraint belt 121 are detachably connected to form a closed loop, the number of the first restraint belt 120 and the second restraint belt 121 is multiple, the other end of the first restraint belt 120 is arranged on the surface of the armrest board 103, the leg placement board 110 and the backrest 102, the other end of the second restraint belt 121 is arranged on the surface of the armrest board 103, the leg placement board 110 and the backrest 102, one end of the first restraint belt 120 is detachably connected to one end of the second restraint belt 121 by Velcro, a mother-child buckle or a buckle, Velcro is preferably used in this application, an empty slot 125 and a card slot are opened on the surface of the armrest board 103, the empty slot 125 and the card slot are connected, the inner wall of the empty slot 125 is movably connected with a connecting rod 126, the other end of the connecting rod 126 is movably connected with a shell 127, the surface of the shell 127 is provided with a cushion 118, and the shell 127 can be inserted into the card slot.

[0044] In this embodiment, the patient's legs, hands and waist can be restrained by the first restraint belt 120 and the second restraint belt 121 to prevent the seat from tipping over due to the patient's lack of self-control. A pull ring 128 is provided on the surface of the shell 127, and the shell 127 can be pulled by the pull ring 128 to flip along the connecting rod 126 until a corner of the shell 127 is inserted into the slot. When the patient changes his position, the patient's head or waist comes into contact with the cushion 118 on the shell 127, and the force is applied mainly to the top of the cushion 118 on the shell 127. At this time, a downward force is applied to the shell 127, and the corner of the shell 127 is inserted into the slot and cannot continue to move upward, thereby supporting the patient.

[0045] Specifically, the working principle of a safety seat for heart failure patients provided in this application is:

[0046] The patient sits on the cushion 100, and then turns over the armrest board 103, so that the bottom of the armrest board 103 abuts against the top of the fixing frame 101, thereby completing the fixation of the armrest board 103. The patient can place a mobile phone or tablet in the placement slot 104 according to the use needs, and support it through the support plate 105, so as to divert the patient's attention;

[0047] The patient can place his legs on the surface of the leg placement board 110, and at the same time, he can rotate the rotating rod 107 to a suitable angle and then rotate the threaded ring 109 to squeeze the rotating rod 107 through the threaded cone sleeve 108 so that the leg placement board 110 is at a suitable angle to meet the patient's use needs;

[0048] The air storage chamber 112 can be inflated and deflated by the air pump 113 or the inflation hole 114 and the deflation hole 115. The chair reclining angle of the patient can be adjusted by changing the amount of gas in the air storage chamber 112 to adapt to the application of different patients. In addition, since the rubber pad 111 is made of soft material, the probability of pressure sores in patients is reduced.

[0049] The first restraint belt 120 and the second restraint belt 121 can be used to restrain the patient's legs, hands and waist to prevent the seat from tipping over due to the patient's inability to control himself.
