Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a leg plate linkage device and a sickbed.
Background
In intensive care, critically ill patients lose self-care ability, are very inconvenient to get up, turn over and lean on, and often need medical care personnel to assist the critical patients. In order to reduce the labor intensity of medical staff, hospitals mostly adopt electric sickbeds with manual or automatic control functions in intensive care units.
Some high-grade electric sickbeds generally mainly comprise components such as a bedstead, 3-4 bed boards, side guardrails, a head foot board, an anti-collision wheel, a back board control motor, a foot board control motor, a caster, a pedal locking device and the like. The user can adjust the back plate, the inclination angle of the thigh plate, the overall height of the bed surface, the front-back inclination angle, the left-right rollover angle and the like by operating the control panel or the liquid crystal touch display and clicking the buttons. More advanced electric sickbeds are provided with leg plates which are composed of thigh plates and lower leg plates, one-key control operation can be carried out aiming at special positions needed clinically, such as Flower positions, special positions, reverse special positions, heart chair positions and the like, the labor intensity of medical staff is greatly reduced, and the electric sickbeds are more and more widely applied.
On the other hand, in the critical care area, good fluid management is of great importance for critically ill patients with hemodynamically unstable conditions. Hypovolemia may lead to organ hypoperfusion, hypoxia and metabolic dysfunction, and overload may lead to pulmonary edema, craniocerebral edema and third interstitial fluid accumulation, both of which may seriously affect patient prognosis. The volume status and the responsiveness to the fluid treatment of the patient can be accurately judged, and the effect of the fluid treatment can be finally determined. The passive leg lifting test (PLR) is a simple and effective method for evaluating the volume responsiveness of a patient, can non-invasively and reversibly reflect heart preload and heart function states comprehensively, and is increasingly applied in clinic. Thus, PLR function was clinically manifested (passive Leg lifting test).
The existing sickbeds mostly adopt the following two structures:
the linkage of the thigh plate and the shank plate is realized by using the chute with the buckle position of the shank plate frame motor, and the method has the defects that two points are large: (1) medical personnel must rise the biggest stroke to shank grillage motor earlier, ensure that patient thigh angle reaches the biggest angle, the spout of manual operation area knot position rises the shank board to be parallel with the thigh board again, the knot position of recycling spout is fixed the spout, just calculate to accomplish an operation, (2) when withdrawing, because the structure of spout self, need slide the spout to the biggest stroke and toward retracting again, put down shank grillage motor after the withdrawal targets in place again, because of the knot position of spout is more weak, it slides to cause the knot position department easily, there is certain danger.
Utilize the motor of installing at last bedstead to promote the shank grillage, make thigh grillage and shank grillage go up and down simultaneously, this method has two great drawbacks: (1) the thigh plate and the shank plate are assembled on the upper bed frame and need to be lifted in parallel, the control requirement on the motor is high, and (2) the structure is not compact, the stroke of the shank plate frame motor is large, and the motor is difficult to select.
