Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a prone position ventilation turning device and a kneeling position supporting method thereof. Background Art

[0002] Prone ventilation is one of the important treatment measures for patients with moderate to severe acute respiratory distress syndrome. It can effectively improve the patient's oxygenation index, improve the imbalance of pulmonary ventilation and blood flow, and re-expand the collapsed alveoli on the dorsal side. At the same time, under the action of gravity, the secretions in the lungs and trachea can be well drained, and it can reduce the pressure of the heart and mediastinum on the sagging lung area. It is a simple, economical and effective treatment method for patients with severe acute respiratory distress syndrome. Prone ventilation of patients needs to be achieved by turning over. Currently, turning over an adult patient requires the cooperation of 3 to 5 people. Specifically, turning sheets are laid on the upper and lower sides of the patient's body and aligned, and both sides are rolled up towards the patient at the same time. Medical staff on both sides cooperate to grab the rolled-up part of the turning sheet and move the patient to one side of the bed. Then the patient is lifted up and turned 180° to complete the turning action. This type of turning method requires laying a turning sheet under the patient in advance, and requires the cooperation of multiple people to operate. It is cumbersome to use. In addition, it can only maintain the standard prone ventilation posture of the patient lying flat. During long-term (not less than 12 hours) standard prone ventilation, the face needs to be kept on the side for a long time, which can easily cause discomfort to the patient. If necessary, sedation and analgesia are also required throughout the process, which is extremely inconvenient to use. Summary of the invention

[0014] The kneeling support method of the prone position ventilation turning device comprises the following steps:

[0015] a. When turning a patient in a supine position for prone ventilation, the turning frame is supported by two sets of walking mechanisms and moved to the bed position, ensuring that the turning frame is moved down to be placed on the bed surface and parallel to the patient. Then, one end of the external plug of the three extension belts is passed under the patient, and the plug is passed under the patient and pulled in the reverse direction to the top of the turning frame. By pulling one end of the external plug of the three extension belts, the patient's body is pulled to the top side of the turning frame. At this time, the patient lies flat on the top side of the turning frame, with the patient's face facing down and placed in the concave hole position of the shoulder support plate, ensuring that the endotracheal tube can be extended along the concave hole to remain unobstructed;

[0016] b. When the patient in the prone position needs to be adjusted to the kneeling ventilation state, the shoulder support is pulled up by the folding assembly, and the lumbar support is driven to turn up by the shoulder support, so that the turning frame is folded into a step shape as a whole.

[0017] c. At the same time, the lifting motor drives the lifting screw to rotate, and the lifting screw drives the lifting block to drive the assembly part and the locking rod to support the shoulder support plate to move up, ensuring that the shoulder support plate is always in a horizontal state. At this time, the waist support plate is folded upward, and the entire turning frame is folded and supported to form a step shape, thereby supporting the patient to lie prone in a kneeling position, reducing the pressure on the abdominal aorta and promoting venous return;

[0018] d. When the prone ventilation is completed and the patient needs to be restored to the supine bed position, the turning motor is used to drive the driving gear to rotate, and the driving gear is engaged with the transmission gear to form a reduction gear mechanism, so that the transmission gear is used to slowly drive the transmission shaft to rotate under the support of the rotating sleeve, and then the transmission shaft is used to support the locking rod to drive the turning frame to rotate as a whole. When the turning frame rotates 90 degrees, the patient is in the lateral position. Then the restraint component on the patient's body is released, and the entire device is disassembled and removed. Then the patient is pushed to continue to turn 90 degrees to achieve supine lying, completing the prone ventilation and turning action.

[0019] The beneficial effect is that: the present invention sets a turning frame as a supporting structure for supporting the patient to perform prone ventilation, uses three sets of extension belts of the restraining components to extend under the patient, and uses the extension belts to pull the patient in the supine position to turn to the top side of the turning frame, so as to quickly realize the patient's prone position conversion action, and does not require multiple people to cooperate with the turning sheet to perform the turning action, which is convenient to use;

When turning a patient in a supine position over for prone ventilation, the turning frame is supported by two sets of walking mechanisms (9) and moved to the bed position, ensuring that the turning frame is moved down to be placed on the bed surface and in parallel with the patient, and then one end of the external plug (403) of the three extension belts (401) is passed under the patient, and the plug (403) is passed under the patient and pulled in the reverse direction to the top of the turning frame, and the patient's body is pulled to the top side of the turning frame by pulling one end of the external plug (403) of the three extension belts (401). At this time, the patient lies flat on the top side of the turning frame, with the patient's face facing downward and placed at the concave hole (103) of the shoulder support plate (1), ensuring that the endotracheal tube can be extended along the concave hole (103) to remain unobstructed; b. When the patient in the prone position needs to be adjusted to a kneeling ventilation state, the shoulder support plate (1) is pulled upward by the folding assembly (5), and the lumbar support plate (2) is turned upward by the shoulder support plate (1), so that the turning frame is folded into a step shape as a whole. During the operation, the traction motor (504) and the lifting motor (601) outside the shoulder support plate (1) work synchronously, and the traction motor (504) is used to drive the traction screw (505) to rotate, and then the traction screw (505) is used to drive the synchronous block (502) to slide along the slide frame (501), and the synchronous block (502) is used to pull the two sets of traction arms (506) to drive the shoulder support plate (1) to slide in the direction close to the leg support plate (3); c.

At this time, the waist support plate (2) is folded upward, and the entire turning frame is folded and supported to form a step shape, thereby supporting the patient to lie prone in a kneeling position, reducing the pressure on the abdominal aorta and promoting venous return; d. When the prone position ventilation is completed and the patient needs to be restored to the supine position in bed, the turning motor (702) drives the driving gear (703) to rotate, and the driving gear (703) is engaged with the transmission gear (804) to form a reduction gear mechanism, so that the transmission gear (804) slowly drives the transmission shaft (801) to rotate under the support of the rotating sleeve (701), and then the transmission shaft (801) supports the locking rod (10) to drive the turning frame to rotate as a whole. When the turning frame rotates 90 degrees, the patient is in the lateral position, and then the restraint component (4) on the patient's body is released, and the entire device is disassembled and removed, and then the patient is pushed to continue to turn 90 degrees to lie supine, completing the prone position ventilation and turning action.
