Abstract

Aiming at the problem that 180-degree turnover of a large patient is difficult to realize in a medical intensive care sickbed which can easily convert the patient from a supine position to a prone position, namely the existing sickbed has the standard width which is difficult to meet the requirement of 180-degree turnover of the large patient, the invention designs the sickbed which can assist medical care personnel to easily change the body position of the severe patient between the supine position and the prone position, and meanwhile, the two sides of the sickbed can be widened.

Description

Medical bed

Technical Field

The invention relates to the field of medical equipment, in particular to a sickbed.

Background

"diagnosis and treatment of coronavirus pneumonia" protocol (trial seventh edition): for patients with severe Acute Respiratory Distress Syndrome (ARDS), pulmonary reoccurrence is recommended. With sufficient human resources, ventilation should be performed in prone position for more than 12 hours per day. In prone position, poor mechanical ventilation, as conditions permit, should consider extracorporeal membrane oxygenation (ECMO) as soon as possible. Thus, prone position ventilation is an important method of treating ARDS.

Prone position ventilation is mentioned in "diagnosis and treatment of novel coronavirus pneumonia" (trial eighth edition): for administration of transcranial high flow oxygen therapy (HFNC) or non-invasive ventilation (NIV), the PaO2/FiO2 is less than 200 mmHg. Patients receiving HFNC or NIV are recommended to carry out prone position ventilation at the same time under the condition of no contraindication, namely the patient is conscious and is ventilated in a prone position, and the treatment time in the prone position is more than 12 hours. Secondly, the risk of failure of the patient to use HFNC or NIV therapy is high, and close examination of the patient's symptoms and signs is required. If the condition is not good after short-time (1-2 hours) treatment, especially after the prone position treatment, hypoxemia is still not improved, or the respiratory frequency, tidal volume are too large, or the effort of inhaling is too strong, etc., the treatment effect of HFNC or NIV is often poor, and invasive mechanical ventilation treatment should be performed in time. The opportunity for ECMO start-up. Under the optimal mechanical ventilation condition (FiO 2 is more than or equal to 80 percent, the tidal volume is 6 ml/kg ideal body weight, PEEP is more than or equal to 5 cmH2O, no contraindication exists), the protective ventilation and prone position ventilation effects are poor, one of the following effects is met, and ECMO is considered and evaluated as early as possible, wherein (i) PaO2/FiO2 is less than 50 mmHg and exceeds 3 hours; ② PaO2/FiO2 is less than 80 mmHg and exceeds 6 hours; ③ the pH value of the arterial blood is less than 7.25, the PaCO2 is more than 60 mmHg is more than 6 hours, and the respiratory frequency is more than 35 times/minute; fourthly, the respiratory frequency is more than 35 times/time, the pH value of the arterial blood is less than 7.2, and the platform pressure is more than 30cmH 2O; combined with cardiogenic shock or sudden cardiac arrest. Fourthly (patients treated by ECMO) patients who are difficult to maintain oxygenation function or have strong inspiratory effort, have obvious consolidation of two-lung gravity-dependent areas or need active airway secretion drainage can be ventilated in combination with prone position. The patient who is sick to bed is changed position regularly, prevents pressure injury. According to the nursing standard, the nursing of noninvasive mechanical ventilation, invasive mechanical ventilation, artificial airway ventilation, prone position ventilation, sedation and analgesia, extracorporeal membrane lung oxygenation diagnosis and treatment is made.

The problem is that in the ICU ward of the new coronary pneumonia, the patient turns over one body, and 7-8 experienced medical personnel wearing protective clothing are needed. Therefore, we have designed a medical intensive care bed (patent application No. 202120521222.3, patent application No. 202010888136.6) that allows easy conversion of patients from supine to prone positions. However, we have found that for large patients the bed is not wide enough, and we have devised a bed that can be widened.

Disclosure of Invention

The invention aims to design a sickbed which can help medical care personnel to easily change the body position of a severe patient between a supine position and a prone position, and meanwhile, the two sides of the sickbed can be widened.
