Description

Sick bed convenient to patient vomits

Technical Field

The invention relates to a sickbed, in particular to a sickbed convenient for patients to vomit.

Background

At present, a problem generally exists in a hospital, when a patient vomits, the patient needs to have family or medical care personnel to transfer a vomit cup, particularly, the patient who just has performed an operation and cannot walk freely and be paralyzed, the patient needs to have the family or the medical care personnel to accompany the patient at any time, otherwise, when the patient vomits, the patient does not have the vomit cup to vomit onto a sickbed or underground, the sickbed can be polluted, and meanwhile, peculiar smell generated by vomit can be emitted into the air, so that the rest of the patient in the same sickroom is influenced. Although the medical staff can place the vomit cup beside the patient to facilitate the patient to vomit, the patient is difficult to get up, and the vomit cup is easy to overturn, and the peculiar smell placed beside the patient can influence the rest of the patient.

Patent application CN108670631A sick bed convenient to patient vomits, including the mounting panel, the cushion, place the seat, the vomiting basin, the diaphragm, first slide rail, first slider, including a motor, an end cap, a controller, and a cover plate, first gear, branch, even board, first rack, the fixture block, the bed board, the landing leg, first wheel, the connecting plate, the second slide rail, the second slider, the cutting ferrule, first spring, the connecting rod, corotation button, reversal button and supporting shoe, the mounting panel is installed in the wall left side, mounting panel left side upper portion is connected with the cushion, mounting panel left side middle part slope is connected with places the seat, it is equipped with the vomiting basin to place in the seat. The equipment can move the bed board leftwards through the reverse rotation of the motor, so that a patient can vomit vomitus into the vomit basin, the patient is prevented from vomitus to a sickbed or the ground, and the influence of the vomitus on the environment can be avoided; and the patient lies prone and vomits on the bed board to can avoid patient to fall to the ground, but this in-process needs nurse's switch motor, and nurse's needs accompany always, and if when vomiting, nurse's untimely opening the motor can lead to patient to vomit to the bed, so still there is the inconvenience.

Therefore, how to develop a sickbed which can realize that a patient can get up by himself and automatically transfer a vomit cup to the patient and is convenient for the patient to vomit is the problem to be solved by the patent.
