AI Technical Summary
During the tracheal intubation process, it is difficult to accurately determine the depth of the tracheal catheter inserted into the trachea. The existing technologies such as bronchoscopy and X-ray examination have limitations, such as inconvenience to determine the relative position between the catheter and the trachea, high radioactivity, long time consumption, and inability to conduct real-time monitoring.
An ultrasonic positioning tracheal catheter is designed to fix the airbag to the outer side wall of the tube body and the rubber tube and ring sleeve to the inner side wall of the airbag. Ultrasonic waves are used to detect the position of the airbag, and the size of the airbag is adjusted by pulling the linkage rod and pulling rope, thereby realizing the detection of the depth of the catheter insertion.
Ultrasonic positioning of the tracheal catheter can accurately detect the depth of the tracheal catheter inserted into the tracheal, avoiding the limitations of traditional methods, such as no bronchoscopy and X-ray examination, reducing radioactive exposure and examination time, and real-time monitoring is achieved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tracheal tubes, in particular to an ultrasound-positioned tracheal tube. Background Art
[0002] When performing tracheal intubation, medical staff can use a wireless laryngoscope to insert it into the human mouth, place the laryngoscope blade between the epiglottis and the root of the tongue, and then insert the tracheal tube into the human trachea along the groove of the laryngoscope. After the tracheal tube is inserted to the designated position, the medical staff can put the tracheal cannula on the tube and insert the cannula along the tube to the appropriate depth of the trachea. Generally, it is difficult to observe the depth of the tube inserted into the trachea with a wireless laryngoscope, and because the tube is thin, there is a large gap between the tube and the tracheal wall, and the ultrasonic wave is poorly transmitted in the air, resulting in ultrasound equipment, such as B-ultrasound, also difficult to observe the depth of the tube inserted into the trachea. Generally, medical staff confirm the insertion position of the tube through a bronchoscope or X-ray. However, the position of the tracheal tube can be clearly determined through a bronchoscope, but it is inconvenient to determine the relative position of the tube and the trachea, so it is impossible to judge the depth of the tube inserted into the trachea. X-ray examination has problems such as high radioactivity, long time consumption, and inability to perform real-time monitoring, which is relatively inconvenient. Utility Model Content
[0003] The purpose of the utility model is to provide an ultrasound-positioned endotracheal tube to solve the problems raised in the above-mentioned background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] An ultrasonically positioned tracheal catheter comprises a tube body, wherein the tube body is a sealed structure at one end, and an air bag is fixedly connected to one end of the outer wall of the tube body, and a plurality of connecting holes are opened at one end of the outer wall of the tube body, and the interiors of the plurality of connecting holes are all connected to the interior of the air bag.
[0006] Furthermore, the airbag is provided with a plurality of vent holes on opposite sides, a rubber tube is fixedly connected between two vent holes located on opposite sides of the airbag and parallel to each other, the plurality of rubber tubes correspond one-to-one to the plurality of connecting holes, and the interiors of the plurality of rubber tubes are connected to the interiors of two adjacent vent holes.
[0007] Furthermore, a plurality of guide wires are fixedly connected to the inner wall of the tube body.
[0008] Furthermore, the outer side walls of the plurality of rubber tubes are movably sleeved with ring sleeves, one end of the plurality of ring sleeves are fixedly connected with connecting ropes, and one end of the plurality of connecting ropes are fixedly connected to the inner side wall of the airbag.
[0009] Furthermore, a linkage rod is arranged inside the tube body, the other ends of the plurality of ring sleeves are fixedly connected with pull ropes, one ends of the plurality of pull ropes pass through adjacent connecting holes, and one ends of the plurality of pull ropes are fixedly connected to the outer side wall of the linkage rod.
[0010] Furthermore, the outer side walls of the plurality of rubber tubes are fixedly connected to two limiting rings, and the plurality of ring sleeves are slidably clamped between the two limiting rings on adjacent rubber tubes.
[0011] Furthermore, one end of the linkage rod is fixedly connected with a pull plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The method inserts the tube body into the human trachea and then injects physiological saline into the airbag through the opening of the tube body, so that the saline fills the airbag, thereby causing the airbag to expand and block the trachea. The user can then use ultrasound to detect the position of the airbag. The user can then put a sleeve on the tube body, and after inserting the tube body to a designated position in the human trachea, the user pulls a linkage rod, so that the linkage rod pulls a plurality of rings toward the tube body through a plurality of pull ropes, so that the plurality of rings rely on adjacent connecting ropes to pull the airbag to move toward the tube body, making the airbag smaller. The linkage rod is then pulled, so that the plurality of rings pull the adjacent rubber tubes toward the tube body, thereby making the airbag smaller again. The user can then remove the tube body together with the airbag from the inside of the sleeve, so that the insertion depth of the tube body into the trachea can be detected by ultrasound.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 5 In an embodiment of the utility model, an ultrasound-positioned endotracheal tube includes a tube body 100, which is a sealed structure at one end, and an airbag 200 is fixedly connected to one end of the outer wall of the tube body 100, and a plurality of connecting holes 101 are opened at one end of the outer wall of the tube body 100, and the interiors of the plurality of connecting holes 101 are connected to the interior of the airbag 200.
[0022] Specifically, by inserting the tube body 100 into the trachea, the insertion depth of the tube body 100 is determined based on the user's experience, and then a liquid such as physiological saline is injected through the opening of the tube body 100, so that the saline is injected into the airbag 200 through multiple connecting holes 101 to expand the airbag 200, so that the airbag 200 is in close contact with the trachea, and the inside of the airbag 200 is filled with physiological saline, so that it can be detected by ultrasound, and then the user can rely on ultrasonic detection to check the position of the airbag 200 in the human body, so as to facilitate the user to locate the insertion depth of the tube body 100. After the tube body 100 is inserted to the specified depth, the user can put the tracheal tube on the tube body 100 until the tube hits the airbag 200, and then the user can withdraw the airbag 200 together with the tube body 100 from the inside of the tube to complete the tracheal intubation.
[0023] Embodiment 1
[0024] like Figure 3 As shown, in this embodiment, a plurality of ventilation holes 201 are provided on opposite sides of the airbag 200, and a rubber tube 210 is fixedly connected between two ventilation holes 201 which are respectively located on opposite sides of the airbag 200 and are parallel to each other. The plurality of rubber tubes 210 correspond one-to-one to the plurality of connecting holes 101, and the interiors of the plurality of rubber tubes 210 are connected to the interiors of two adjacent ventilation holes 201, and a plurality of guide wires 300 are fixedly connected to the inner wall of the tube body 100.
[0025] In this embodiment, after normal saline is injected into the airbag 200, the airbag 200 blocks the patient's trachea. At this time, the multiple rubber tubes 210 automatically recover due to their own elasticity, so that the multiple rubber tubes 210 automatically recover to a tubular shape to facilitate the flow of air, and the patient can breathe using the rubber tubes 210. The tube body 100 is a hose, and the guide wire 300 is an elastic thin metal wire, which is convenient for the user to use the guide wire 300 to increase the toughness of the tube body 100 and facilitate the insertion of the tube body 100 into the human trachea.
[0026] like Figure 3-5 As shown, in the present embodiment, the outer walls of the plurality of rubber tubes 210 are movably sleeved with a ring sleeve 400, and one end of the plurality of ring sleeves 400 is fixedly connected with a connecting rope 410, one end of the plurality of connecting ropes 410 is fixedly connected to the inner wall of the airbag 200, a linkage rod 430 is provided inside the tube body 100, the other ends of the plurality of ring sleeves 400 are fixedly connected with a pull rope 420, and one end of the plurality of pull ropes 420 passes through adjacent connecting holes 101, and one end of the plurality of pull ropes 420 is fixedly connected to the outer wall of the linkage rod 430.
[0027] During specific implementation, after the tube body 100 is inserted to a specified depth and the tracheal tube sleeve is moved on the tube body 100 to a specified position of the trachea, the user can pull the linkage rod 430, which is an elastic plastic rod. By pulling the linkage rod 430, multiple ring sleeves 400 are driven to move synchronously toward the tube body 100, and multiple ring sleeves 400 pull the outer walls of the airbag 200 toward the tube body 100 through the connecting rope 410, thereby shrinking the airbag 200, and then continue to pull the linkage rod 430, so that the multiple ring sleeves 400 pull the middle parts of the adjacent rubber tubes 210 to bend toward the tube body 100, so that the airbag 200 is further deflated, and then the user can pull the tube body 100 out of the sleeve, thereby facilitating the user to pull out the tube body 100.
[0028] Embodiment 2
[0029] On the basis of the first embodiment, the ring sleeve 400 is limited by providing a limiting ring 211 , so that the ring sleeve 400 first pulls the outer wall of the airbag 200 toward the tube body 100 through the connecting rope 410 .
[0030] like Figure 4-5 As shown, in this embodiment, the outer walls of multiple rubber tubes 210 are fixedly connected to two limit rings 211, multiple ring sleeves 400 are slidably clamped between the two limit rings 211 on adjacent rubber tubes 210, and one end of the linkage rod 430 is fixedly connected to a pull plate 440.
[0031] During specific implementation, the user can pull the linkage rod 430 to move through the pull plate 440, which is convenient for the user to use, and the multiple pull ropes 420 are in contact with one end of the adjacent connecting hole 101, and the adjacent pull ropes 420 are limited by one end inside the connecting hole 101, so that when the linkage rod 430 pulls the pull rope 420, the pull rope 420 can drive the ring sleeve 400 to translate due to the limit of the end of the adjacent connecting hole 101. The ring sleeve 400 is made of rubber material and is not easy to deform due to its own elasticity. The user can control the ring sleeve 400 to be not skewed through the limiting ring 211, so that when the linkage rod 430 is pulled, the multiple ring sleeves 400 will first use the adjacent connecting holes 101 to move horizontally. The rope 410 pulls the outer wall of the airbag 200 to move toward the tube body 100, so that the airbag 200 is initially deflated, and then pulls the linkage rod 430 to make the multiple ring sleeves 400 contact the adjacent rubber tubes 210, and pulls the rubber tubes 210 toward the tube body 100, so that when the airbag 200 deflates again, when the airbag 200 deflates for the first time, the airbag 200 may still be partially blocked in the trachea. At this time, the multiple rubber tubes 210 still remain unobstructed for the patient to breathe, and then when the airbag 200 deflates again, the airbag 200 is not easy to block the trachea. At this time, the rubber tube 210 can be bent to make the airbag 200 smaller again, so that it can be pulled out of the sleeve.
[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
