Description

Technical Field

[0001] The present invention relates to the technical field of respiratory assistance, and in particular to an insertion respiratory assistance device for comatose patients. Background Art

[0002] The respiratory assistance device for comatose patients mainly provides support for patients who cannot breathe independently, ensures the patency of the airway and maintains normal oxygen supply. Depending on the specific situation of the comatose patient, the selection and use of the respiratory assistance device may be different. When the patient is in a coma and cannot breathe independently, endotracheal intubation is a common choice. Endotracheal intubation inserts a tube into the patient's trachea and connects it to a mechanical ventilation device to allow air to enter the lungs and expel carbon dioxide. Endotracheal intubation is usually suitable for patients with a deep coma who cannot maintain effective ventilation. However, when the patient is in a coma, the direction of his face may not be convenient for intubation, especially when medical staff are transporting the patient. Due to the long journey time, the patient needs to be intubated before being transported, and the breathing tube must be kept inserted during the transportation process. The comatose patient in the prior art cannot automatically straighten the patient's face with the inserted respiratory assistance device, and the patient's face cannot be facing up, which is not convenient for intubation.

[0032] The patient's head is located on the headrest 208. Since the patient is in a coma, the patient's face is not necessarily facing upwards. In the initial state, the connecting tube head 203 and the extension tube 202 are not located above the headrest 208, which is convenient for placing the comatose patient on the bed board 110. The controller 105 controls the adjusting motor 211 to rotate. The adjusting motor 211 rotates to drive the motor gear 212 to rotate, and the adjusting worm 215 is driven to rotate through the screw gear 213, thereby driving the worm gear 214, the rotating arc plate 206 and the headrest 208 to rotate. The rotating roller 216 provides guidance for the arc groove 207. The rotation of the headrest 208 drives the patient's head to rotate, so that the patient's face faces upwards. Then the controller 105 controls the steering motor 218 to rotate, thereby driving the eccentric wheel 219 to rotate. When the eccentric column 22 After the ventilator enters the groove of the steering wheel 221, the eccentric column 220 drives the steering wheel 221, the rotating tube 201, the extending tube 202 and the connecting tube head 203 to rotate above the patient's face. At this time, the torsion spring between the rotating tube 201 and the steering sleeve 222 is twisted, and the steering motor 218 stops.

The ventilator passes oxygen into the patient's respiratory tract through the rotating tube 201, the extending tube 202 and the connecting tube head 203. When the use is completed, the steering motor 218 rotates, and after the eccentric column 220 is separated from the groove of the steering wheel 221, the torsion spring between the steering sleeve 222 and the rotating tube 201 is reset, so that the extending tube 202 and the connecting tube head 203 leave the top of the head support 208 again.

[0033] The working principle of an insertable breathing assistance device for a comatose patient disclosed in the present invention is as follows: the comatose patient is placed on a bed board 110, with the patient's head located on a headrest 208. The medical staff holds the handrail 106 and can push the frame 101 and the bed board 110 to move under the action of four walking wheels 104. The controller 105 can control the extension and retraction of the bottom electric cylinder 111, thereby driving the movement of the bottom movable frame 112, thereby driving the rotation of the rotating bending frame 113, thereby driving the vertical rod 114 and the bed board 110 to rise and fall, and the sliding block 115 slides in the bottom sliding groove 116. The upper sliding sleeve 108 and the sliding block 115 provide support and guidance for the bed board 110, so that the bed board 110 always remains parallel to the frame 101. The patient's head is located on the headrest 208. Since the patient is in a coma, the patient's face is not necessarily facing upwards. In the initial state, the connecting tube head 203 and the extension tube 202 are not located above the headrest 208, which is convenient for placing the comatose patient on the bed board 110. The controller 105 controls the adjusting motor 211 to rotate. The adjusting motor 211 rotates to drive the motor gear 212 to rotate, and the adjusting worm 215 is driven to rotate through the screw gear 213, thereby driving the worm gear 214, the rotating arc plate 206 and the headrest 208 to rotate. The rotating roller 216 provides guidance for the arc groove 207. The rotation of the headrest 208 drives the patient's head to rotate, so that the patient's face faces upwards. Then the controller 105 controls the steering motor 218 to rotate, thereby driving the eccentric wheel 219 to rotate. When the eccentric column 22 After the ventilator enters the groove of the steering wheel 221, the eccentric column 220 drives the steering wheel 221, the rotating tube 201, the extending tube 202 and the connecting tube head 203 to rotate above the patient's face. At this time, the torsion spring between the rotating tube 201 and the steering sleeve 222 is twisted, and the steering motor 218 stops. At this time, the medical staff connects the disposable inserted breathing tube to the connecting tube head 203, and then inserts the breathing tube into the patient's nose. The ventilator passes oxygen into the patient's respiratory tract through the rotating tube 201, the extending tube 202 and the connecting tube head 203. When the use is completed, the steering motor 218 rotates, and after the eccentric column 220 is separated from the groove of the steering wheel 221, the torsion spring between the steering sleeve 222 and the rotating tube 201 is reset, so that the extending tube 202 and the connecting tube head 203 leave the top of the head support 208 again.
