Description

Special bedsore-resistant hospital bed for hospital

Technical Field

The utility model relates to a hospital bed, in particular to a special bedsore-resistant hospital bed for hospitals.

Background

Bedsore is tissue necrosis and pressure ulcer caused by that the body is pressed for a long time, local tissues are pressed for a long time, and are ulcerated and necrotized due to continuous ischemia, hypoxia and malnutrition, and when blood passes through the skin and subcutaneous fat, the blood is blocked by the continuous pressure of capillary pressure, and can not properly supply nutrition required by the skin and subcutaneous tissues. Is one of the common complications of long-term bedridden patients. The acne is called as "acne" in traditional Chinese medicine, and is caused by abnormal qi and blood circulation and blockage of channels and collaterals due to the deficiency of qi and blood caused by long-term illness, long-term bed rest and local compression, and the skin cannot be nourished, if the treatment is not timely carried out, the flesh, the bone and the dew are combined to be infected, and septicemia is caused in severe cases, so that death is caused.

At present, a mattress on a sickbed in a hospital has many problems, for example, the sickbed generally adopts a bed board and a mattress, the structure is simpler, but the air permeability is poor, and for some patients lying on the sickbed for a long time, bacteria are easily bred on the back of the patients, so that skin bacterial infection is caused; and to some sick heavy patients, can't turn over always, the health is pressed and can appear pressing the sore phenomenon on the mattress for a long time, these patients generally through medical personnel turn over it constantly, can alleviate and press the sore phenomenon, so not only increased medical personnel's work load, to pressing the therapeutical effect that the sore played, because it is too big to turn over the action moreover, probably aggravate patient's state of an illness.

Consequently, some special anti decubital sick beds of hospital have appeared on the market, for example the utility model patent of the grant bulletin number CN206675656U discloses "prevent bedsore's sick bed", the sick bed includes two rows of pivots that set up side by side the level and the bed board that comprises the strip shaped plate that the polylith is parallel to each other, is provided with the eccentric wheel in the every pivot, and is adjacent the eccentric opposite direction of eccentric wheel, the quantity of strip shaped plate equals with the quantity of the epaxial eccentric wheel of commentaries on classics, and each the strip shaped plate supports on two corresponding eccentric wheels, is provided with hand mechanism in the one end of every pivot, drives the pivot through hand mechanism and rotates to drive the vertical motion of strip shaped plate, and the motion opposite direction of two adjacent strip shaped plate, thereby constantly change the impetus of patient's organism, prevent decubital production.

However, the above-mentioned hospital bed has the following disadvantages:

1. although the sick bed can drive the pivot through hand rocking mechanism and rotate to drive the vertical motion of bar shaped plate, with this constant impetus that changes patient's organism, because the position (promptly the impetus) homogeneous phase of bar shaped plate and patient's organism contact at every turn is the same, and is gone down for a long time, the position of patient's organism and bar shaped plate contact also produces the bedsore easily.

2. The hospital bed drives the rotating shaft and the eccentric wheel on the rotating shaft to rotate through the hand-operated mechanism, so that the strip-shaped plate is driven to vertically move, and therefore when the hospital bed is used, medical staff or family members of patients need to be present, and operation is particularly inconvenient.
