Abstract
Description
Technical Field
[0001] This utility model relates to the field of bronchoscope technology, specifically to a bronchoscope structure. Background Technology
[0002] Newborns are infants who have been born from the time the umbilical cord is tied until they are less than 28 days old. Some newborns are susceptible to external bacterial infections, such as pneumonia or bronchitis, during which time medical staff need to use bronchoscopy to examine their condition.
[0003] Chinese Utility Model Publication No. CN210408364U discloses a bronchoscope structure, including a tracheal segment inserted into the human body and a handle segment located outside the human body. The tracheal segment and the handle segment are connected end to end and have operating channels that communicate with each other to the end of the tracheal segment and the end of the handle segment. The side of the handle segment is also provided with an outwardly extending side extension, which has an oxygen supply channel. One end of the oxygen supply channel is connected to the operating channel, and the other end is connected to an oxygen supply device that provides oxygen.
[0004] This device improves ease of operation by delivering oxygen. However, when supplying oxygen to the operating channel through the oxygen supply channel in the side extension to provide the patient with the necessary oxygen for breathing, the depth to which the bronchoscope is inserted into the child's trachea varies depending on the child's height, condition, or affected area. When the insertion is shallow, some of the air vents may not be in the child's trachea but in the throat or mouth. As a result, the delivered oxygen flows from the throat into the air and is eventually discharged to the outside, reducing the oxygen utilization rate. Furthermore, the flow of discharged oxygen in the throat increases the child's discomfort. Therefore, its practicality is not very good, and there is room for improvement. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a bronchoscope structure that improves practicality.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a bronchoscope structure, including a tracheal section, with several exhaust holes for delivering oxygen provided on the side wall of the tracheal section, inserted into the trachea of the human body. The tracheal section has a through-tube inside, and a handle is fixedly provided at the end of the tracheal section outside the human body. The handle has a cavity inside, and the cavity and the tube of the tracheal section are through-connected. An extension tube is connected through the side wall of the handle, and one end of the extension tube passes through the cavity of the handle. An oxygen delivery tube is inserted into the extension tube. The oxygen delivery tube passes through the tube of the tracheal section and extends to the end of the tracheal section away from the handle. The oxygen delivery tube passes through the tube and exposes exhaust holes at different positions to deliver oxygen.
[0009] Furthermore, a scale strip is provided on the side wall of the oxygen delivery tube, and the scale strip is coated with a conspicuous color.
[0010] Furthermore, the outer wall of the oxygen delivery tube is attached to the inner wall of the tracheal tube, and the oxygen delivery tube is made of plastic with a low coefficient of friction.
[0011] Furthermore, the side wall of the extension tube is provided with a threaded hole and a bolt is threadedly connected thereto. The lower part of the bolt is rotatably connected to an extrusion plate via a rotating shaft.
[0012] Preferably, the extension tube has a groove inside, the extrusion plate slides in the groove, and the end face of the extrusion plate near the oxygen delivery tube is pressed tightly against the outer wall of the infusion tube.
[0013] Preferably, the oxygen delivery tube is provided with a limiting block, one end face of which is attached to the pipe opening wall of the extension tube, and a pull ring is provided at the lower part of the limiting block.
[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the present invention provides a bronchoscope structure with the following advantages:
[0016] This bronchoscope structure determines the location of the vent hole in the trachea based on the depth of insertion into the child's trachea. Then, by pulling the air supply tube, the tube opening is moved closer to the throat, ensuring that the vent hole in the trachea is not blocked by the oxygen supply tube, while the vent hole in the throat is blocked. In this way, when delivering oxygen, the oxygen in the oxygen supply tube will be delivered to the trachea through the vent hole in the trachea, instead of being delivered to the throat, thus improving the oxygen utilization rate and reducing discomfort, thereby enhancing its practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-7This utility model discloses a bronchoscope structure, including a tracheal section 1. Several exhaust ports 2 for oxygen delivery are provided on the side wall of the tracheal section 1, which is inserted into the trachea of the human body. A through-tube is provided inside the tracheal section 1. A handle 3 is fixedly attached to the end of the tracheal section 1 outside the human body. Medical personnel grasp the handle 3 and then insert the tracheal section 1 into the child's body. A cavity is provided inside the handle 3, and the cavity and the through-tube of the tracheal section 1 are arranged through it. An extension tube 4 is connected through the side wall of the handle 3. One end of the extension tube 4 passes through the cavity of the handle 3 and can communicate with the through-tube of the tracheal section 1. An oxygen delivery tube 5 is inserted into the extension tube 4. The oxygen delivery tube 5 is located in the tracheal section... The oxygen delivery tube 5 travels through the tube 1 and extends to the end of the trachea 1 away from the handle 3. One end of the oxygen delivery tube 5 is inserted from the extension tube 4 into the cavity of the handle 3, and then enters the tube of the trachea 1. The oxygen delivery tube 5 travels through the tube and exposes the exhaust holes 2 at different positions to deliver oxygen. Depending on the depth of the trachea 1 inserted into the child's trachea, grasp the oxygen delivery tube 5 and pull it outward from the extension tube 4 to move the opening of the oxygen delivery tube 5 within the trachea 1. As it moves, the oxygen delivery tube 5 no longer blocks the exhaust holes 2 on the trachea 1. With each pull, the exhaust holes 2 are gradually unblocked, making it easy to keep the exhaust holes 2 in the trachea unblocked, while the exhaust holes 2 in the throat and mouth are blocked by the oxygen delivery tube 5.
[0027] Please see Figure 5 The oxygen delivery tube 5 has a scale strip 6 on its side wall. The scale strip 6 is painted with a bright color. Medical staff can accurately judge the length of the oxygen delivery tube 5 that has been pulled out by the changes in the values on the scale strip 6, and thus determine whether the exhaust port 2 at different positions on the trachea 1 is blocked.
[0028] Please see Figure 2 The outer wall of the oxygen delivery tube 5 is attached to the inner wall of the tracheal section 1 to prevent the oxygen output from the oxygen delivery tube 5 from entering the gap between them and flowing to the blocked exhaust port 2 to be discharged to the outside, without entering the child's trachea. The oxygen delivery tube 5 is made of plastic with a low coefficient of friction to reduce the friction between the oxygen delivery tube 5 and the tracheal section 1, making it easier to pull the oxygen delivery tube 5.
[0029] Please see Figure 1-2 The extension tube 4 has a threaded hole 7 on its side wall and a bolt 8 is threadedly connected to it. The lower part of the bolt 8 is rotatably connected to a compression plate 9 via a rotating shaft. The extension tube 4 has a sliding groove 10 inside, and the compression plate 9 slides in the sliding groove 10. The end face of the compression plate 9 close to the oxygen tube 5 is tightly pressed against the outer wall of the infusion tube. After the length of the oxygen tube 5 is adjusted, the medical staff rotates the bolt 8 in the forward direction. The bolt 8 rotates in the threaded hole 7, which drives the compression plate 9 to move in the sliding groove 10 until it is pressed against the outer wall of the oxygen tube 5, generating a holding force and clamping the oxygen tube 5.
[0030] Please see Figure 6-7 A limiting block 11 is provided on the oxygen delivery tube 5. The limiting block 11 can prevent the oxygen delivery tube 5 from extending into the tracheal section 1. One end face of the limiting block 11 is attached to the tube wall of the extension tube 4. A pull ring is provided at the lower part of the limiting block 11. Medical staff can grab the pull ring and pull it to pull the oxygen delivery tube 5 out of the tracheal section 1 and adjust the length of the oxygen delivery tube 5 pulled out.
[0031] In summary, with this bronchoscope structure, during use, medical staff determine the appropriate insertion depth of the tracheal section 1 into the trachea based on the child's age or the location of the lesion. After insertion, the medical staff can reverse the rotation of bolt 8, causing the compression plate 9 to move within the slide groove 10, away from the oxygen delivery tube 5. Then, they can grasp the puller and pull it outwards, using the graduations 6 on the oxygen delivery tube 5 to determine the length pulled out. The opening of the oxygen delivery tube 5 moves within the tracheal section 1, and as it moves, it no longer obstructs the trachea. When the exhaust port 2 on part 1 is no longer blocked by the oxygen delivery tube 5, stop pulling the oxygen delivery tube 5, turn the bolt 8 in the forward direction, and the bolt 8 rotates in the threaded hole 7, driving the extrusion plate 9 to move in the slide groove 10 until it is pressed against the outer wall of the oxygen delivery tube 5, clamping the oxygen delivery tube 5. Finally, connect an oxygen supply device to one end of the oxygen delivery tube 5 to deliver oxygen into the oxygen delivery tube 5. The oxygen is discharged from the opening of the oxygen delivery tube 5 and then discharged into the child's trachea from the no longer blocked exhaust port 2 for oxygen supply.
