Example two

Referring to fig. 1, 3-10, a multifunctional nursing chair for physical examination center comprises a seat plate 1, a movable backrest 2 is arranged at one side of the upper end of the seat plate 1, the movable backrest 2 is rotatably connected with the seat plate 1 through a rotating shaft 3, wheels 4 are movably mounted at the lower end of the seat plate 1, a lying auxiliary mechanism 5 is arranged at the other side of the upper end of the seat plate 1, a transfusion warning mechanism 6 is arranged at the upper end of the seat plate 1, an emergency blocking mechanism 7 is arranged inside the transfusion warning mechanism 6, the transfusion warning mechanism 6 comprises armrest plates 601, the armrest plates 601 are symmetrically mounted at the left and right sides of the seat plate 1 in an equal number manner, mounting blocks 602 are fixedly mounted at the upper end of the armrest plates 601, vertical sliding grooves 603 are formed in the upper ends of the mounting blocks 602, movable frames 604 are slidably connected inside the vertical sliding grooves 603, return springs 605 are fixedly connected between the lower ends of the movable frames 604 and the bottoms of the vertical sliding grooves 603, a fixed block 606 is fixedly arranged at the lower end of the middle of the mounting block 602, when a medical staff places a medicine bottle on the fixed block 606, the movable frame 604 moves downwards under the action of gravity, then the amount of liquid medicine in the medicine bottle is continuously reduced, the movable frame 604 moves upwards under the action of a return spring 605 to reset in the process of reducing the liquid medicine, a trigger cavity 607 is fixedly arranged at one side opposite to the mounting block 602, a trigger straight rod 608 is movably arranged in the trigger cavity 607, the upper end of the trigger straight rod 608 is fixedly connected with the movable frame 604, a touch switch 609 is fixedly arranged at the upper end of the inner cavity of the trigger cavity 607, alarms of the touch switch 609 are electrically connected through a lead, when the movable frame 604 vertically moves upwards, the trigger straight rod 608 can move upwards and contact the touch switch 609, so that the alarms are automatically sent to the outside, a hanging hook 610 is fixedly arranged at the lower end of the fixed block 606, a rotating disk 611 is movably sleeved outside the fixed block 606, a torsion spring 612 is arranged between the rotating disk 611 and the fixed block 606, and an L-shaped rod 613 is fixedly connected to the lower end of the rotating disk 611.

The working principle is as follows:

during operation, medical personnel can hang the liquid medicine bottle upside down on hanging hook 610, then manual rotatory rotating disc 611, rotating disc 611 makes torsional spring 612 compressed and save elastic potential energy when rotating disc 611 rotates, next, medical personnel can relieve rotating disc 611, subsequently, rotating disc 611 can be rotatory under torsional spring 612's effect, rotating disc 611 makes L shape pole 613 rotate in step when rotating disc 611 rotates, can make the transfer line under the vertical state twine on L shape pole 613 when L shape pole 613 rotates, thereby reached and to have carried out the effect of roll-up to the transfer line before the infusion automatically, can effectively avoid the transfer line overlength to hang on other objects at the in-process that the nursing chair removed.

The movable frame 604 then moves downward under the force of gravity, and the downward movement of the movable frame 604 presses and compresses the return spring 605.

Next, as the amount of the liquid medicine in the liquid medicine bottle is decreased, the movable frame 604 is moved upward by the elastic force of the return spring 605, and the trigger rod 608 is moved upward synchronously while the movable frame 604 is moved upward.

When the liquid medicine in the liquid medicine bottle is about to be exhausted, the movable frame 604 moves to the upper end of the vertical sliding groove 603 under the elastic force of the return spring 605, at the moment, the lower end of the trigger straight rod 608 presses the touch switch 609 and enables the touch switch 609 to be switched on, and the touch switch 609 is electrically connected with the alarm inside through a lead, so that the alarm can give an alarm after the touch switch 609 is switched on.

The patient hears and can close the transfusion valve immediately after the police dispatch sound to call medical personnel and pull out the needle or change dressings the operation, thereby reached and to have reminded patient's liquid medicine automatically and be about to the effect of exhausting, can avoid to a great extent because the liquid medicine exhausts and lead to patient's blood backward flow, thereby improved the security of infusion greatly.

To sum up: according to the invention, through the mutual matching between the rotating disc 611 and the L-shaped rod 613, when the rotating disc 611 rotates under the action of external force, the torsion spring 612 is compressed and accumulates elastic potential energy, when the external force disappears, the rotating disc 611 can rotate reversely under the action of the torsion spring 612, the L-shaped rod 613 can rotate synchronously when the rotating disc 611 rotates, and the infusion tube in a vertical state can be wound on the L-shaped rod 613 when the L-shaped rod 613 rotates, so that the effect of automatically winding the infusion tube before infusion is achieved, and the phenomenon that the overlong infusion tube is hung on other objects in the moving process of the nursing chair can be effectively avoided; in addition, according to the invention, through the mutual matching between the movable frame 604 and the triggering straight rod 608, when the movable frame 604 moves to the upper end of the vertical chute 603 under the action of the elastic force of the return spring 605, the touch switch 609 can be switched on under the action of the triggering straight rod 608, the alarm can give an alarm after the touch switch 609 is switched on, and the patient can immediately close the infusion valve after hearing the alarm sound and call medical personnel to carry out needle pulling or dressing change operation, so that the effect of automatically reminding the patient that the liquid medicine is about to be exhausted is achieved, the blood backflow of the patient due to the exhaustion of the liquid medicine can be avoided to a great extent, and the safety of infusion is greatly improved.
