Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an endotracheal intubation device. Background Art
[0002] Tracheal intubation is a typical means of assisted breathing in an interventional manner. In the prior art, the device for performing tracheal intubation generally includes a catheter and an inflatable balloon attached to the outside of the distal end of the catheter. During the process of performing tracheal intubation, the distal end of the catheter is pushed through the patient's mouth and the proximal end of the trachea to a predetermined position at the distal end of the trachea. Subsequently, the balloon is inflated outside the patient's body using an inflation device so that the balloon is inflated and rests against the wall of the patient's trachea, thereby achieving positioning of the distal end of the catheter and avoiding axial and radial movement of the distal end of the catheter. Another function of the balloon is that the balloon contacts the wall of the trachea to implement a seal, thereby intercepting fluid substances upstream of the balloon (such as secretions such as sputum) from flowing downward along the trachea to the lungs.
[0003] However, there is still a possibility that fluid substances may leak from between the airbag and the wall of the trachea. The reason is that the cross-sectional shape of the airbag after being inflated cannot perfectly match the trachea. The reasons for the inability to perfectly match include: the cross-sectional shapes of the tracheas of different patients are different, while the airbags used are universal airbags with the same cross-sectional shape; the deformation stiffness of the patient's trachea in the front and rear directions is different, while the deformation stiffness of the airbag in all directions is basically the same.

[0036] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.
[0037] like Figures 1 to 5 As shown, an embodiment of the utility model discloses an endotracheal intubation device, which includes: a catheter 20, an expandable component 10, an inflation tube, an inflation device 51, a suction tube and a suction device 52.
[0038] During the intubation process, the distal end of the catheter 20 passes through the patient's oral cavity and the proximal end of the trachea 100 in sequence and is pushed to the distal end of the trachea 100, while the proximal end of the catheter 20 is located outside the oral cavity. The proximal end of the catheter 20 is connected to an oxygen supply device, which is used to provide oxygen to the catheter 20, so that the provided oxygen is directly supplied to the patient's lungs through the catheter 20.
[0039] like Figure 3 and Figure 4 As shown, the expandable component 10 is attached to the distal end of the catheter 20. The expandable component 10 is pushed to the distal end of the trachea 100 along with the distal end of the catheter 20. After being pushed to the distal end of the trachea 100, the expandable component 10 is expanded to contact the inner tube wall of the trachea 100, thereby supporting and positioning the distal end of the catheter 20 to limit the axial and radial movement of the distal end of the catheter 20. In the present utility model, the expandable component 10 includes two airbags, that is, a first airbag 11 and a second airbag 12. The first airbag 11 and the second airbag 12 are connected in series. The first airbag 11 and the second airbag 12 are connected by a connecting sleeve 13. The first airbag 11, the connecting sleeve 13 and the second airbag 12 are all sleeved on the radial outer side of the distal end of the catheter 20 and fixed relative to the catheter 20. The first airbag 11 is located on one side of the proximal end of the second airbag 12.
[0040] The inflation tube includes a first inflation tube 31 and a second inflation tube 32; the middle tube section of the first inflation tube 31 runs in the inner hole of the catheter 20, the proximal end of the first inflation tube 31 passes through the proximal end of the catheter 20 and is located on the outside of the oral cavity, the distal end of the first inflation tube 31 passes through the outside of the catheter 20 and extends into the first airbag 11, the middle tube section of the second inflation tube 32 runs in the inner hole of the catheter 20, the proximal end of the second inflation tube 32 passes through the proximal end of the catheter 20 and is located on the outside of the oral cavity, and the distal end of the second inflation tube 32 passes through the outside of the catheter 20 and extends into the second airbag 12. The proximal ends of the first inflation tube 31 and the second inflation tube 32 are both connected to the inflation device 51, and the proximal end of the first inflation tube 31 is installed with a first switch valve 61, and the upstream of the first switch valve 61 is provided with a first exhaust port 311, and the proximal end of the second inflation tube 32 is installed with a second switch valve 62, and the upstream of the second switch valve 62 is provided with a second exhaust port 321. In this way, after the expandable component 10 is pushed to the distal end of the trachea 100, the first switch valve 61 and the second switch valve 62 are opened, and the inflation device 51 is used to synchronously inflate the first airbag 11 and the second airbag 12 through the first inflation tube 31 and the second inflation tube 32, so that the first airbag 11 and the second airbag 12 are expanded and contact the tube wall.
[0041] After the two airbags are inflated, since the two airbags are arranged in series at intervals, a chamber is formed between the two airbags and the inner tube wall of the trachea 100. In this way, if the sealing effect between the first airbag 11 and the inner tube wall of the trachea 100 is poor, resulting in an undesirable leakage of the fluid material upstream of the expandable component 10 (i.e., upstream of the first airbag 11), the chamber can collect the leaked fluid material. At the same time, the second airbag 12 performs a second sealing and interception on the fluid material, thereby improving the interception effect of the fluid material to a certain extent. In addition, the two airbags in series have better compliance with the direction of the patient's trachea 100, which is conducive to positioning the distal end of the catheter 20 and facilitating the airbag to intercept the fluid material. Since the chamber is used to collect fluid materials, it may be called a liquid storage chamber 14.
[0042] The suction tube includes a first suction tube 41 and a second suction tube 42; the main tube section of the first suction tube 41 is located in the inner hole of the catheter 20, the proximal end of the first suction tube 41 extends out of the proximal end of the catheter 20 and is located outside the oral cavity, the distal end of the first suction tube 41 extends to the position of the liquid storage chamber 14, and radially extends into the liquid storage chamber 14 to be used for sucking the fluid material in the liquid storage chamber 14, the main tube section of the second suction tube 42 is located in the inner hole of the catheter 20, the proximal end of the second suction tube 42 extends out of the proximal end of the catheter 20 and is located outside the oral cavity, the distal end of the second suction tube 42 extends to one side of the proximal end of the first airbag 11, and the end passes through the catheter 20 and faces the proximal wall 111 of the first airbag 11 for sucking the fluid material on the proximal side of the first airbag 11 (i.e., upstream of the expandable component 10). The proximal end of the first suction pipe 41 and the proximal end of the second suction pipe 42 are both connected to the suction device 52. The proximal end of the first suction pipe 41 is installed with a third switch valve 63, and the proximal end of the second suction pipe 42 is installed with a fourth switch valve 64. If the first switch valve 61 is opened, Figure 5 As shown, the suction device 52 can suck the fluid material into the liquid storage chamber 14 through the first suction pipe 41. If the second switch is turned on, as shown in FIG. Figure 4 As shown, the suction device 52 can suck the intercepted fluid material toward the proximal end of the first airbag 11 through the second suction tube 42 .
[0043] The first airbag 11 is provided with a plurality of fluid channels 112, which are arranged circumferentially, the distal end of each fluid channel 112 passes through the liquid storage chamber 14, the proximal end of the fluid channel 112 is covered by the proximal wall 111 of the first airbag 11, and a hard lining tube 1121 is provided in each fluid channel 112 to support the fluid channel 112. The proximal wall 111 of the first airbag 11 and the region corresponding to each fluid channel 112 are provided with a sealing gap 1111, preferably, the sealing gap 1111 is opened at an angle, so that the sealing gap 1111 has a wider sealing surface, and the sealing gap 1111 is opened by elastic deformation based on the pressure difference on both sides.
[0044] The following describes the method for using the above-mentioned endotracheal intubation device.
[0045] The catheter 20 is inserted into the patient's trachea 100, and the distal end of the catheter 20 is pushed to the distal end of the trachea 100, the first switch valve 61 and the second switch valve 62 are opened, and the first airbag 11 and the second airbag 12 are inflated synchronously using an inflating device 51 such as an inflatable kettle, such as Figure 3 As shown, the first airbag 11 and the second airbag 12 are expanded to contact the inner tube wall of the trachea 100 .
[0046] The proximal end of the catheter 20 is connected to an oxygen supply device, and the oxygen supply device is used to actively supply oxygen to maintain the patient's breathing.
[0047] During the period of maintaining the patient's breathing by using the oxygen supply device, fluid substances can be pumped out periodically. The fluid substances can be pumped out in the following two ways.
[0048] First way:
[0049] like Figure 5 As shown, the third switch valve 63 is opened, and the suction device 52 sucks fluid material into the liquid storage chamber 14 between the two airbags through the first suction tube 41. If there is fluid material in the area, the fluid material is removed by the first suction tube 41. At this time, the sealing gap 1111 at the proximal end of the fluid channel 112 is opened to balance the pressure in the liquid storage chamber 14. If there is no fluid material on the proximal side of the first airbag 11, the gas enters the liquid storage chamber 14 through the fluid channel 112 to balance the pressure in the liquid storage chamber 14. If there is fluid material on the proximal side of the first airbag 11, the fluid material enters the liquid storage chamber 14 through the fluid channel 112 and is then removed by the first suction tube 41, thereby also removing the fluid material on the proximal side of the first airbag 11. This method is a necessary suction method during the entire use of the tracheal intubation device.
[0050] Second way:
[0051] like Figure 4As shown, the fourth switch valve 64 is opened, and the suction device 52 sucks the fluid material on one side of the proximal end of the first airbag 11 through the second suction tube 42. This method can only suck the fluid material on one side of the proximal end, but cannot suck the fluid material in the liquid storage chamber 14. This method is an unnecessary suction method during the entire use of the endotracheal intubation.
[0052] Before removing the endotracheal tube device from the patient's trachea 100, first, open the first exhaust port 311 so that the first airbag 11 is first deflated and contracted, and the fluid material (if any) intercepted by the first airbag 11 will flow down into the liquid storage chamber 14, and then, use the first suction tube 41 to suck the fluid material into the liquid storage chamber 14, so as to completely remove the fluid material, and then, open the second exhaust port 321 to allow the second airbag 12 to be deflated and contracted. Since the fluid material in the liquid storage chamber 14 is completely removed, no fluid material will flow back into the lungs. Finally, remove the endotracheal tube device from the trachea 100.
[0053] In some preferred embodiments, the middle portion of the proximal wall 111 of the first airbag and the middle portion of the proximal wall 121 of the second airbag 12 are both axially retracted, so that the edge of the proximal wall 111 of the first airbag is higher than the middle portion, and the edge of the proximal wall 121 of the second airbag 12 is higher than the middle portion. This structure is conducive to the airbag intercepting fluid substances.
