A sputum suction tube device for suctioning different positions of the airway

Abstract

The present invention relates to the field of auxiliary sputum suction, and in particular to a sputum suction tube device for suctioning different positions of an airway. The pipeline portion in the present invention is formed by attaching a sputum suction tube and an oxygen supply tube. The oxygen supply tube delivers oxygen to the airway to avoid hypoxemia caused by a reduction in the amount of gas supplied to peripheral lung tissue during sputum suction. A control head is sleeved on the surface of the oxygen supply tube and can rotate relative to the oxygen supply tube. It can be understood that during the sputum suction process, the control head is rotated to allow the sputum suction tube connected to the control head to rotate in the airway, that is, the sputum suction tube can achieve 360° all-round sputum suction in the airway, and can suction secretions in all positions of the entire artificial airway and the respiratory tract, greatly reducing the sputum suction time and eliminating blind spots that cannot be suctioned.

Description

Technical Field

[0001] The invention relates to the field of auxiliary sputum suction, in particular to a sputum suction tube device for suctioning different positions of an airway. Background Art

[0002] Mechanically ventilated patients need airway management, and the key to airway management is to suction secretions in the airway in time. However, there are two problems when suctioning airway secretions: mechanical ventilation requires endotracheal intubation or tracheotomy. Whether it is nasal or oral endotracheal intubation, or tracheotomy, the artificial channel is arc-shaped. When the suction tube passes through the endotracheal intubation or tracheotomy tube, it will stick to the lumen wall on the outer arc side. After exiting the endotracheal intubation or tracheotomy tube, its end can only enter the respiratory tract along the arc. The suction tube cannot reach most positions of the endotracheal intubation or tracheotomy tube and the airway, and cannot clear the airway secretions that have not been reached; at the same time, during suction, since suction uses negative pressure, in addition to suctioning, gas is also sucked out, resulting in a reduction in the amount of gas reaching the peripheral lung tissue, which is prone to hypoxemia; in addition, when there are more airway secretions, the suction time is longer, which will affect the patient's ventilation effect and cause hypoxemia. Summary of the invention

[0003] To solve the above problems, the present invention provides a sputum suction tube device for suctioning airways in different directions, which aims to solve the problems in the prior art that long sputum suction time makes patients prone to hypoxemia and there are blind spots for sputum suction.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a sputum suction tube device for suctioning different positions of the airway, comprising a pipeline part and a control head connected to each other, the pipeline part is in an arc shape, and is characterized in that:

[0005] The pipeline part includes a sputum suction tube and an oxygen supply tube whose ends are fitted to each other, and both ends of the sputum suction tube and the oxygen supply tube are open structures;

[0006] The control head is sleeved on the surface of the oxygen supply tube and can rotate relative to the oxygen supply tube;

[0007] The middle part of the oxygen supply tube is a free end formed by bending.

[0008] Furthermore, the control head includes a rotating handle and a sliding guide rail, the sliding guide rail is circumferentially arranged at the head end of the oxygen supply tube, the rotating handle is provided with a slider slidably connected to the sliding guide rail, and the rotating handle is also connected to the sputum suction tube.

[0009] Furthermore, a side hole is provided at the end of the sputum suction tube, and there are three or more (including three) side holes, and the spacing between every two adjacent side holes is the same.

[0010] Furthermore, a switch is provided on the surface of the sputum suction tube, and the switch is controllably connected to the negative pressure generating device.

[0011] Furthermore, the free end is spiral-shaped.

[0012] The beneficial effects of the present invention are:

[0013] 1. The pipeline part of the present invention is formed by attaching a sputum suction tube and an oxygen supply tube. The oxygen supply tube delivers oxygen to the airway to prevent the patient from suffering from hypoxemia due to a reduction in the amount of gas supplied to the peripheral lung tissue during sputum suction.

[0014] 2. The control head is sleeved on the surface of the oxygen supply tube and can rotate relative to the oxygen supply tube. It can be understood that during the suction process, the control head is rotated to make the suction tube connected to the control head rotate in the airway, that is, the suction tube can achieve 360° all-round suction in the airway, and can suck secretions from all directions of the entire artificial airway and respiratory tract, greatly reducing the suction time and eliminating the blind spots of suction.

[0019] See also Figure 1-2 As shown, the present invention relates to a sputum suction tube device for suctioning different positions of the airway, comprising a pipeline portion and a control head connected to each other, the pipeline portion is in an arc shape, and is characterized in that:

[0020] The pipeline part includes a sputum suction tube 1 and an oxygen supply tube 2 whose ends are fitted to each other, and both ends of the sputum suction tube 1 and the oxygen supply tube 2 are open structures;

[0021] The control head is sleeved on the surface of the oxygen supply tube 2 and can rotate relative to the oxygen supply tube 2;

[0022] The middle portion of the oxygen supply tube 2 is a free end 3 formed by bending.

[0023] In the specific example, an oxygen machine and a negative pressure machine are also provided. The output end of the negative pressure machine is connected to the sputum suction tube 1, and the output end of the oxygen machine is connected to the oxygen supply tube 2. The negative pressure machine extracts sputum in the airway, and the oxygen machine provides oxygen to increase the oxygen concentration of the gas supplied to the peripheral lung tissue.

[0024] The use principle of the present invention is:

[0025] By introducing the end of the pipe portion into the human airway and rotating the control head, the suction tube 1 is rotated so that the suction tube 1 can suck sputum from multiple directions of the airway. It should be noted that in the process of rotating the control head, the free end 3 is deformed along the rotation direction, and the free end 3 is tortuous, then the free end 3 is spirally rotated clockwise or counterclockwise, and the spiral free end 3 is in a passage state.

[0026] It should also be noted that the pipeline portion is a hose made of plastic material.

[0027] Furthermore, the control head includes a rotating handle 4 and a sliding guide rail 5, the sliding guide rail 5 is circumferentially arranged at the head end of the oxygen supply tube 2, the rotating handle 4 is provided with a slider slidably connected to the sliding guide rail 5, and the rotating handle 4 is also connected to the sputum suction tube 1; the above design is a preferred embodiment of the present invention, and the sputum suction tube 1 is rotated along the peripheral direction of the sliding guide rail 5 by rotating the rotating handle 4.

[0028] It should be noted that fixing pads 6 are sleeved on both sides of the sliding rail 5, and the sliding rail 5 is fixed on the oxygen supply pipe 2 through the fixing pads 6;

[0029] It should be noted that the present invention is vertically introduced into the patient's airway.

[0030] Furthermore, a side hole 8 is provided at the end of the suction tube 1, and there are more than three (including three) side holes 8, and the spacing between each two adjacent side holes is the same; the spacing between two adjacent side holes is the same to ensure that when the side hole contacts the bronchial wall and is blocked, the side hole of the suction tube 1 away from the bronchial wall continues to be open; the pipeline of the suction tube 1 must be unobstructed to suck out the sputum in the airway. If the end opening is blocked, the side hole 8 is open to keep the pipeline unobstructed.

[0031] Furthermore, a switch 7 is provided on the surface of the sputum suction tube 1, and the switch 7 is control-connected to the negative pressure generating device; by adopting the above scheme, the negative pressure generating device can be quickly controlled during the sputum suction process.

[0032] Furthermore, the free end 3 is spiral-shaped.

[0033] The use process of the invention is:

[0034] When suctioning a patient with endotracheal intubation or tracheotomy, the suction tube 1 is connected to the negative pressure machine, and negative pressure is generated at the end of the suction tube 1; the direction of the end of the suction tube 1 is adjusted by rotating the handle 4 to ensure that the arc direction of the end of the suction tube 1 is consistent with the arc of the endotracheal intubation tube or tracheotomy tube; when suctioning begins, the tube portion is sent into the airway through the endotracheal intubation tube or tracheotomy tube, and the rotating handle 4 is rotated left and right every time 1-2 cm of the length is sent in to ensure that the end of the tube portion can rotate 360°, so that secretions from all directions of the entire artificial airway and respiratory tract can be suctioned.

[0035] In this specific embodiment, the head end of the sputum suction tube 1 is located inside the rotating handle 4 .
