Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of weighing sickbeds, in particular to an electronic weighing sickbed for critically ill bedridden patients. BACKGROUND

[0002] In the process of clinical treatment, the body weight change of critically ill bedridden patients is a very important nutritional indicator, which is a key link in the diagnosis and treatment process, and its data directly affects the calculation of drug dosage, the development of nutrition support plan and the assessment of disease changes. During treatment, the body weight of critically ill bedridden patients needs to be measured regularly. At present, due to the fact that critically ill bedridden patients often have consciousness disorders, limited limb movement or unstable vital signs, they cannot independently cooperate with the conventional weighing operation and are not convenient to transfer for weighing, so the critically ill patients lie on the electronic weighing sickbed, which can facilitate the weighing of the patient's body weight while being treated.

[0003] In the prior art, although the traditional electronic weighing sickbed for critically ill bedridden patients can meet the basic needs of weighing, there are still at least the following deficiencies during use: the critically ill bedridden patients lying on the electronic weighing sickbed cannot independently turn over for a long time, which is prone to sweat secretion, urine leakage, body fluid exudation and other situations, resulting in that the mattress is in a wet state for a long time. On the one hand, the wet environment will make the internal filling of the mattress (such as sponge and latex mattress layer) absorb water and increase in weight. If the patient is weighed directly in the wet state, the additional water weight will seriously interfere with the weighing result, further exacerbate the weighing accuracy error, and affect the diagnosis and treatment judgment. On the other hand, the wet mattress is a breeding ground for bacteria and mold, which is prone to cause skin infection and pressure sores in patients. If the mattress is not dried in time for a long time, the incidence of pressure sores in critically ill patients will increase, which not only increases the pain of patients, but also prolongs the hospitalization period and increases the medical cost.

[0004] Therefore, we propose an electronic weighing sickbed for critically ill bedridden patients to solve the above problems. SUMMARY
