Description

A kind of prone position ventilation therapy mattress

【Technical field】

The invention relates to the technical field of medical devices, in particular to a prone position ventilation therapy mattress.

【Background technique】

Prone position ventilation is currently an important method for severe acute respiratory distress syndrome, and has been proven by a large number of studies to improve oxygenation and prognosis in patients with severe acute respiratory distress syndrome. Prone position ventilation can improve the patient's ventilation/blood flow, promote lung recruitment, reduce the patient's respiratory frequency and work of breathing, promote secretion drainage, thereby improving the patient's oxygenation.

Traditional prone position ventilation treatment is generally used for patients with endotracheal intubation, and requires prone position ventilation time of more than 12 hours per day. In addition, it also requires large doses of analgesics and sedative drugs, which increases the risk of unstable circulation, pressure ulcers and various diseases. There is a risk of the tubes being broken or falling off, and the patient needs to be turned over regularly. When turning over, multiple people are required to assist, which increases the workload of medical staff. In addition, it is necessary to use several patient pillows and place the pillows in advance to assist in maintaining the patient's prone position, and its comfort is difficult to guarantee.

In order to facilitate the adjustment of the air pressure gear, the first connecting pipe 51, the second connecting pipe 52 and the third connecting pipe 53 are each provided with a barometer 50 and are respectively provided with a first air valve 56, a second air valve 57 and a third air valve. Valve 58, the air pressure regulating device 5 is provided with a control module 501 electrically connected to the first air valve 56, the second air valve 57, the third air valve 58 and the barometer 50, and a control panel 502 electrically connected to the control module 501, The control panel 502 is provided with control switches for controlling the inflation pressure of the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4. The air pressure adjustment of the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4 can be controlled by operating the control switch on the control panel 502, which is very convenient.

The control switches provided on the control panel 502 correspond to the headrest airbag 2, the thoracoabdominal pillow airbag 3 and the footrest airbag 4 in one-to-one correspondence. When adjusting the headrest airbag 2, adjust the control switch (pressure increase or decrease) corresponding to the headrest airbag 2, the control module 501 controls the first air valve 56 to open, the second air valve 57 and the third air valve 58 to close , the control module 501 controls the air pressure pump 54 to inflate or deflate the headrest airbag 2 through the output pipe 55 and the first connecting pipe 51 (during this period, the air pressure gauge 50 on the first connecting pipe 51 can display the air pressure of the headrest airbag 2 in real time) , thereby adjusting the air pressure of the headrest airbag 2 to a suitable air pressure value. At this time, the control module 501 controls the first air valve 56 to close. When adjusting the thoracoabdominal airbag 3, adjust the control switch (pressure increase or decrease) corresponding to the thoracoabdominal airbag 3, the control module 501 controls the second air valve 57 to open, and the first air valve 56 and the third air valve 58 to close , the control module 501 controls the air pressure pump 54 to inflate or deflate the thoracoabdominal airbag 3 through the output tube 55 and the second connecting tube 52 (during this period, the barometer 50 on the second connecting tube 52 can display the air pressure of the thoracoabdominal airbag 3 in real time. ), thereby adjusting the air pressure of the thoracoabdominal airbag 3 to a suitable air pressure value. At this time, the control module 501 controls the second air valve 57 to close. When adjusting the footrest airbag 4, adjust the control switch (pressure increase or decrease) corresponding to the footrest airbag 4, the control module 501 controls the third air valve 58 to open, and the first air valve 56 and the second air valve 57 to close , the control module 501 controls the air pressure pump 54 to inflate or deflate the footrest airbag 4 through the output pipe 55 and the third connecting pipe 53 (during this period, the air pressure meter 50 on the third connecting pipe 52 can display the air pressure of the footrest airbag 4 in real time. ), thereby adjusting the air pressure of the footrest airbag 4 to a suitable air pressure value. At this time, the control module 501 controls the third air valve 58 to close. Of course, the control panel 502 is also provided with an exhaust switch for simultaneously controlling the deflation of the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4, so that when the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4 are not in use, When pillow air bag 4 is used, its air is evacuated. During emptying, the control module 501 controls the first air valve 56, the second air valve 57 and the third air valve 58 to all open, and controls the air pressure pump 54 to deflate the headrest airbag 2, chest and abdomen pillow airbag 3 and footrest airbag 4. The first air valve 56 , the second air valve 57 and the third air valve 58 are controlled to close until the headrest airbag 2 , thoracoabdominal pillow airbag 3 and footrest airbag 4 are completely emptied.

In order to further improve the comfort of the patient in the prone position, as shown in Figure 3, hand pillows 6 are provided on both sides of the headrest air bag 2 for the patient's hands to rely on. In the same way, the hand pillow 6 can also be configured to be inflatable and have adjustable air pressure like the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4.

In order to facilitate fixing the mattress to the hospital bed to prevent accidental displacement, fixed straps 7 are provided on both sides of the bottom mattress 1 .

The present invention has two uses. When the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4 are completely emptied, the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4 can be accommodated in the first cavity 11 , the second cavity 12 and the third cavity 13, so as to remain flat with the surface of the bottom mattress 1. At this time, the mattress can be used as an ordinary mattress for the patient to lie down and rest normally. When prone treatment is required, there is no need for the patient to change beds, which is very convenient. At this time, the patient is directly turned to the prone position, and the air pressure pump 54 is controlled through the control switch on the control panel 502 to pump the headrest airbag 2, the chest and abdomen pillow airbag 3 and the feet. The pillow airbag 4 is inflated so that the forehead rests on the decompression patch 21 of the headrest airbag 2 (the head is turned to a comfortable position), the chest and abdomen rest on the thoracoabdominal pillow airbag 3, and the feet rest on the footrest airbag 4 , the hand rests on the hand pillow 6. At this time, the patient's knees are bent forward (bottom pad 1), and the patient's overall trunk is in a "bow-shaped" prone position, allowing the collapsed alveoli to recruit and improve the gravity-dependent area. The ratio of ventilation/blood flow can reduce dead space and increase functional residual capacity, improve the movement pattern and position of the diaphragm, facilitate the drainage of secretions, thereby improve oxygenation and clear the airway, reduce the occurrence of ventilator-related lung injury, and reduce the number of patients suffering from oxygen-related injuries. Secondary multiple organ dysfunction and mortality caused by combined disorders. During use, the control switches on the panel 502 can be controlled to adjust the air pressure of the headrest airbag 2, thoracoabdominal pillow airbag 3 and footrest airbag 4 to achieve the optimal prone air pressure for the patient and improve the comfort of use.
