Description

Program-controlled rejuvenating bed

The invention belongs to programme controlled, as to have medical usefulness furniture class.

As everyone knows, old disease, be unable to leave the bed and lose the people of the ability of standing up,, not only cause fatigue because my unable action is in the oppression state a certain position under the body, and because of thrombosis causes numbness, cause inflammation,

Mashed, form decubital ulcer, painful extremely.Therefore need frequently, periodically to want other people to help to stand up, bring very burden to nursery work.Do not find a kind of nursery work that can replace the people up to now as yet, automatically help patient to finish the bed that stands up action.

The objective of the invention is that a kind of can manually to help patient to sit for sleeping in for the requirement that solves above-mentioned patient designs, but self-timing ground helps patient to finish the left and right bed that stands up action-programme controlled rejuvenating bed again.It can alleviate the nursery work burden, more can alleviate and exempt patient's misery.

The present invention-program control is rejuvenating bed-by bedstead, before and after realizing folding and about folding bed drawer, manually sit up action drive part and form with the drive division branch that stands up action about the relay circuit programme-control.

Fig. 1 is rejuvenating bed structure side view, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the structure chart of a drawer, and Fig. 4 is the B-B cutaway view of Fig. 1, and Fig. 5 is the control principle figure of motor.(1)-bedstead among the figure is equipped with four movable castors under the lower limb of bedstead; (2)-the bed drawer; (3)-pole sits up; (4)-hand crank; (5)-the driving reduction box sits up; (6)-the action stop sits up; (7)-about stand up pole; (8)-stand up the driving shaft of action; (9)-front and back support of driving shaft; (10)-the travel switch support; (11)-travel switch refutes bar; (12)-stand up the driving reduction box; (13)-motor; (14)-sit up the action driving shaft; (15), (16)-about stand up the stop of action; (17), the hinge that (18)-realization sits up and moves; (19), the hinge of action is stood up in (20)-realization.Fig. 6 is the layout drawing of travel switch.Travel switch support (10) is contained on the driving shaft support, on the stroke switch bracket, open two long arc-shaped holes, four travel switches of 1WX～4WX are housed thereon, when the bed drawer is set level, refute bar (11) and point in the pros, push down travel switch 2WX and 4WX, when the bed drawer when electric driving condition left part is upwards dug, refute bar and rotate counterclockwise by the B-B view direction, move to and refute bar when pushing down 1WX, upper left action stops, refute bar and clockwise rotate when upper right digging, upper right action stops when pushing down 3WX.Therefore change the position of 1WX and 3WX, i.e. the stop angle of stirring about may command bed drawer.About the maximum angle that stirs be 78 °.

The patient that the seat ability has been stood up in forfeiture needs other people to help to sit up frequently, with solve food problem or for a change posture help to have a rest, nursing staff's driving mechanism that can handly sit up, its reduction box gear ratio is 1: 30, energy self-locking in transmission.Hand action makes driving shaft (14) rotate after slowing down, and pole (3) is slowly propped the first half (head of a bed part) of bed drawer, because transmission can self-locking, so a drawer can be parked in the position of any needs, the maximum angle that sits up is 90 °.For guaranteeing safety, under the bed drawer, stop is housed.The counter-rotating hand crank can be put back to the bed drawer, when bed drawer top is set level and when contact with bedstead fully, and bed drawer promotion travel switch 5WX, the normal opened contact energized causes the condition that can stand up action.About stand up the action be electronic, but but also programme-control of hand control.Press the upper left button of digging, motor rotates, and rotates through reduction box deceleration rear drive shaft (8), and pole is slowly propped bed drawer left side, can manual control stop, and is also program-controlled by the upper left action of travel switch control stopping to finish.Its reduction box is pass to be slowed down by the two-stage worm gear, and gear ratio is very big, i=1: 2000 it can adopt Archimedes's form or Niemann spiral shell wheel form.Lower-left action can manual beginning is also program-controlled begins after certain time-delay automatically, stops when setting level to resetting fully.The action situation on bed drawer the right is identical with the left side.Fig. 7 stands up the electrical schematic diagram that operation control part is divided.1QA～4QA is the startup knob of upper left, lower-left, upper right, four actions in bottom right: 1TA～4TA is the stop button of four actions.These start and stop buttons can be located at diverse location, but are located at head of a bed patients or nursing staff's operation; Many rejuvenating bed start and stop buttons are drawn the back and are concentrated placement, can realize the centralized Control of many sick beds of hospital.1QC is the catalyst of upper left bottom right action, and 2QC is the upper right catalyst in lower-left.1SJ～4SJ is four time relays, is used for controlling four intervals between the action.Do one and stay for some time after standing up action, be the anthropomorphic dummy in sleep nature stand up action, its each time-delay can be adjusted arbitrarily in 1 hour, four action interludes as required can be different.Its cyclic process of standing up can be summarized as follows: when the action that sits up sets back and travel switch 5WX pushed down, the normally opened contact closure of 5WX, can start 1QC if press 1QA, motor is rotated by assigned direction, use the holding contact self-locking, drawer is upper left digs for bed, and when predetermined angle was refuted bar shake-up travel switch 1WX, upper left action stopped.The open and close contact conversion of 1WX, start the 1SJ time relay, open the closing of contact to predetermined time delay relay length and start 2QC, motor counter-rotating beginning to do lower-left action, 2WX conversion 2QC stops during to recovery, start 2SJ simultaneously, dig by predetermined delayed startup 2QC right part, start 3SJ during the 3WX conversion, do the bottom right action by predetermined delayed startup 1QC, restart 1QC through 4WX and 4SJ left part is dug, so can constantly circulate.

Use the design's rejuvenating bed and general bed or sick bed are compared and can be shown following advantage: 1. compare with general sick bed, it can realize periodically automatically standing up action except having the action of sitting up. 2. the arbitrary control of this energy, simulation nursing staff's operation, it stands up action can be manual. Any start-stop can stop to suitable position as required; The position that exercises stop in programme-control can be adjusted arbitrarily, and the length of the time of staying also can be inserted arbitrarily between each action, and long residence time is 1 hour. 3. internal crucible stand up action can separate unit control, the start-stop button of many beds is drawn and is concentrated placement can realize the centralized Control of many beds. 4. stable action is slow, and patient rolls lentamente, avoids manpower to stand up the sense of the discomfort of moving, frustrating wiping of operation fully, has namely removed the heavy burden of nursing staff, has also increased patient's comfortableness. 5. because stable action, comfortable, patient is automatic turn-over body under clear-headed or sleep state termly, thereby health and bed surface contact site can reduce inflammation, more can avoid bedsore.

The design also can make automatically (sit up to move and also use motor-driven), or other embodiment such as full-automatic and manual (if two all available hand crank drivings that pick out of action when having a power failure).

The design is simple in structure, is easy to make, and can alleviate nursing staff's burden, can remove patient's pain as if, so this programme is subjected to patient and medical personnel's welcome deeply.It can be widely used in hospital, sanatorium and the family.
