Description

Technical Field

[0001] The present application relates to the technical field of endotracheal intubation, and in particular to an endotracheal intubation system. Background Art

[0002] Endotracheal tubes are commonly used in medical settings. Their primary function is to ensure a clear airway and provide the necessary oxygen supply. Existing endotracheal tubes are typically used in conjunction with an endoscope. During use, the endoscope is inserted into the endotracheal tube, which is then inserted into the human trachea. The portion of the endoscope that extends into the tube also enters the human trachea along with the tube, posing a risk of cross-infection. After use, the endoscope is cleaned for the next use. However, when an endoscope is used in conjunction with an endotracheal tube, it needs to be reused repeatedly, which can easily lead to cross-infection. To achieve sterilization, the endoscope needs to be cleaned multiple times, making the process complicated. Utility Model Content

[0031] Please refer to Figures 1 to 4 This embodiment provides a tracheal intubation system, including:

[0032] An endoscope 7 includes an operating portion 1 and a scope 2 connected to one side of the operating portion 1;

[0033] The protective conduit 8 includes a disposable tube 4 and a connecting sub-tube 3 connected to one side of the disposable tube 4; the disposable tube 4 and the connecting sub-tube 3 are both sleeved outside the scope body 2, and the connecting sub-tube 3 is detachably connected to the operating part 1;

[0034] The endotracheal cannula 9 includes a handle 5 and a tube body 6 connected to one end of the handle 5; the tube body 6 and the handle 5 are sleeved outside the disposable tube 4, and the handle 5 is detachably connected to the connecting sub-tube 3.

[0035] The endoscope comprises an operating portion 1 and a mirror body 2 connected to one side of the operating portion 1; the operating portion 1 has a hand-held portion, which is covered with a rubber sleeve for easy grasping of the endoscope; a camera 21 is installed at the end of the mirror body 2 away from the operating portion 1, and the curvature and length of the mirror body 2 meet the structural characteristics of the human trachea, so that the tracheal intubation system can enter the human body under visual conditions, and the mirror body 2 is an arc-shaped hard mirror body, which can provide sufficient support for the tracheal intubation system; the disposable tube 4 is a flexible transparent tube, the inner diameter of the disposable tube 4 matches the outer diameter of the mirror body 2, and the disposable tube 4 is replaced after use to reduce the risk of cross infection; a first through hole is opened inside the connecting sub-tube 3, and one end of the disposable tube 4 is inserted into the first through hole The hole is in the hole to realize the connection between the connecting sub-tube 3 and the disposable tube 4. The disposable tube 4 and the connecting sub-tube 3 are both sleeved on the outside of the mirror body 2 to protect the mirror body 2 from damage during use. The end of the connecting sub-tube 3 away from the disposable tube 4 is detachably connected to the operating part 1; the handle 5 is hollow inside, and the outer contour of the handle 5 conforms to ergonomics, ensuring that it is more comfortable to hold and reducing the burden on the hand when holding for a long time; the outer wall of the tube body 6 is in contact with the inner wall of the handle 5, and an air supply pipe 52 extends from the outer wall of the handle 5. The interior of the air supply pipe 52 is connected to the interior of the tube body 6, which is convenient for connecting to the oxygen supply equipment, so that the endotracheal tube 9 can supply air to the human body when it is inserted, thereby ensuring the patient's blood oxygen concentration during treatment.

[0036] When in use, first connect the air supply pipe 52 to the oxygen supply equipment, and then insert the tracheal intubation system into the human body. The endoscope 7 makes the insertion process visual to avoid trauma to the human body. After the tracheal intubation system is inserted into the trachea, the protective catheter 8 and the endoscope 7 can be removed from the tracheal intubation 9, and other instruments (such as therapeutic instruments) can be inserted into the handle 5 of the tracheal intubation 9. In the prior art, the endoscope 7 is directly connected to the endotracheal tube 9, and the portion of the scope 2 that extends into the tube body 6 enters the human trachea together with the tube body 6, resulting in a risk of cross-infection at the end of the scope 2 away from the operating part 1; however, the present application provides a protective catheter 8, and the disposable tube 4 of the protective catheter 8 and the connecting sub-tube 3 completely cover the scope 2. When the endotracheal tube system is inserted into the human trachea, the connecting sub-tube 3 is placed outside the human body, and the portion of the scope 2 that extends into the human trachea is tightly covered by the disposable tube 4, thereby avoiding exposure of the end of the scope 2 away from the operating part 1 to the outside, thereby reducing the possibility of cross-infection.

[0037] In a preferred embodiment, the operating portion 1 has a connector 11 at one end close to the mirror body 2, and a protrusion 12 is provided on the outer wall of the connector 11; a groove 32 is provided on the inner wall of the connecting sub-tube 3, the connecting sub-tube 3 is sleeved on the outside of the connector 11, and the protrusion 12 is clamped in the groove 32.

[0038] Please refer to Figure 2 and Figure 3The end of the operating part 1 close to the mirror body 2 has a cylindrical connector 11, and a second through hole is provided inside the connector 11, and the mirror body 2 is inserted into the second through hole; a protrusion 12 is provided on the outer wall of the connector 11 at the end away from the mirror body 2; a groove 32 is provided on the inner wall of the connecting sub-tube 3 away from the disposable tube 4, and the groove 32 has an opening at the end away from the disposable tube 4, and the shape and size of the groove 32 match the protrusion 12; when assembling the endoscope 7 and the protective catheter 8, the mirror body 2 end of the endoscope 7 is inserted from the side of the connecting sub-tube 3 away from the disposable tube 4, and the mirror body 2 is located in the disposable tube 4, and the protrusion 12 on the connector 11 slides into the open end of the groove 32 and is engaged in the groove 32 to prevent the endoscope 7 and the protective catheter 8 from rotating relative to each other during use.

[0039] In a preferred embodiment, a plurality of first arcuate cuts 61 and second arcuate cuts 62 are alternately provided on the outer wall of the tube body 6 along the extension direction of the tube body 6 , and the bending direction of the first arcuate cuts 61 is opposite to the bending direction of the second arcuate cuts 62 .

[0040] Please refer to Figure 6 The tube body 6 is made of a hard material, such as 304 stainless steel, to prevent the tube body 6 from being deformed due to the material being too soft when it enters the trachea and is compressed; the provision of multiple first arc-shaped cuts 61 and multiple second arc-shaped cuts 62 reduces the rigidity of the tube body 6 to a certain extent, so that multiple gaps are formed on the wall of the tube body 6. The multiple gaps provide the tube body 6 with space that can be extended or contracted, so that the tube body 6 can bend, so that no stress shielding is generated when the tube body 6 enters the human body cavity, thereby avoiding damage to the human body to a certain extent.

[0041] In a preferred embodiment, the central angle corresponding to the first arc-shaped cutout 61 is greater than 180°, and the central angle corresponding to the second arc-shaped cutout 62 is greater than 180°.

[0042] Please refer to Figure 6 The central angles of the first arc-shaped cutout 61 and the second arc-shaped cutout 62 are both greater than 180°, which allows the tube body 6 to have more space for expansion or contraction and can be bent in any direction with a greater degree of bendability.

[0043] In a preferred embodiment, the handle 5 has an insertion channel inside, and the insertion channel includes a first channel and a second channel 51 that are connected to each other. The second channel 51 is a trumpet-shaped structure, and its small-diameter end is connected to the first channel. The end of the first channel away from the second channel 51 is connected to the inside of the tube body 6.

[0044] Please refer to Figure 5The inner diameter of the first channel is consistent with the outer diameter of the tube body 6, and the tube body 6 extends into the first channel; the large-diameter end of the second channel 51 faces the connecting sub-tube 3, and the small-diameter end is connected to the first channel, which facilitates the disposable tube 4 to extend into the tube body 6 or be pulled out from the tube body 6 along the second channel 51 and the first channel, and also facilitates subsequent other instruments to extend into the tube body 6 along the insertion channel.

[0045] In a preferred embodiment, the connecting sub-tube 3 has a cannula connecting portion 33 on the side close to the disposable tube 4. The cannula connecting portion 33 extends into the second channel 51. The outer wall of the cannula connecting portion 33 abuts against the inner wall of the second channel 51. The cross-section of the second channel 51 is elliptical, and the outer contour of the cannula connecting portion 33 is also elliptical.

[0046] Please refer to Figure 8 The cross section of the second channel 51 is elliptical, and the outer contour of the cannula connecting portion 33 is elliptical, and the two are matched. During use, the cannula connecting portion 33 is prevented from rotating relative to the second channel 51, and the protective catheter 8 is prevented from rotating relative to the handle 5, thereby preventing the protective catheter 8 from driving the endoscope 7 to rotate and causing the lens to shift, thereby accurately monitoring the process and position of the tracheal cannula being inserted into the human body.

[0047] In a preferred embodiment, the inner wall of the tube body 6 is spray-coated with a first film 63 .

[0048] Please refer to Figure 7 The first film 63 makes the inner wall of the tube body 6 smooth, making it easy for the disposable tube 4 and other various instruments to be inserted.

[0049] In a preferred embodiment, the outer wall of the tube body 6 is covered with an elastic membrane 64 .

[0050] Please refer to Figure 7 The elastic membrane 64 is used to prevent the tube body 6 from leaking during use, which may cause a decrease in blood oxygen content, and also makes the instrument smoother when inserted into the human body.

[0051] In a preferred embodiment, the end of the tube body 6 away from the handle 5 is spray-coated with a second film inside and outside.

[0052] The end of the tube body 6 away from the handle 5 is the tube head, and the inside and outside of the tube head are sprayed with a second film. The second film is used to ensure that the tube head is smooth and not sharp, and to prevent the tube head from causing trauma to the human trachea during the process of being inserted into the human trachea.
