Abstract
Description
Technical Field
[0001] This utility model relates to a nasal compression hemostasis balloon catheter, and pertains to the field of medical device technology. Background Technology
[0002] Nasal packing is a common method for stopping nasal bleeding. Current nasal hemostasis devices are often designed with an emphasis on hemostasis and ease of operation, but lack pre-planning and targeted solutions for problems that may arise in specific usage scenarios. For example, nasal hemostasis balloons can achieve convenient hemostasis, but existing nasal hemostasis balloons are generally straight tubes. After being inserted into the nasal cavity, the breathing tube is compressed by the nasal cavity wall, causing it to bend and deform, reducing the diameter of the breathing tube and obstructing breathing. Utility Model Content
[0003] The purpose of this invention is to design a nasal compression hemostasis balloon catheter that, when inserted into the nasal cavity, will not obstruct breathing.
[0004] This invention includes a breathing tube, a balloon, and a balloon-inflatable tube with its inner end communicating with the balloon. The breathing tube includes a straight section and a curved section that are interconnected. The straight section is connected to an outer port, and the curved section is connected to an inner port. The balloon is disposed on the curved section. The nasal compression hemostasis balloon catheter designed in this manner can prevent the breathing tube from being compressed by the nasal cavity wall, thus avoiding the narrowing of the breathing tube diameter and obstruction of breathing.
[0005] Furthermore, the balloon inflation tubing includes an inner tubing integrally formed with the breathing tubing and an outer tubing disposed outside the breathing tubing; the inner end of the inner tubing communicates with the balloon; its outer end extends to near the outer port of the breathing tubing and connects with the outer tubing fixed to one side of the breathing tubing. The balloon inflation tubing configured in this manner allows the tubing to avoid the mouth, facilitating fixation to the side of the face and preventing disruption to the patient's normal daily life and eating habits.
[0006] Furthermore, the inner end of the breathing tube extends through the balloon, and the outer surface of its inner port is a smooth arc shape. This design of the breathing tube prevents damage to the nasal cavity wall when inserted into the nasal cavity.
[0007] Furthermore, the outer end of the balloon inflation tube is equipped with a one-way valve, and the inner end of the one-way valve is equipped with an indicator balloon that communicates with the balloon inflation tube.
[0008] Furthermore, the indicator balloon is wrapped around a section of balloon inflation tubing and sealed at both ends, indicating that the indicator balloon is connected to the balloon inflation tubing.
[0009] This invention includes a breathing tube, the angle between its straight and curved sections matching the nasal cavity structure. After the balloon is inserted into the nasal cavity, the breathing tube is not compressed by the nasal cavity wall, ensuring unobstructed breathing. In this invention, the outer tube of the balloon inflates to form an angle with the breathing tube in the top view, allowing the outer tube to avoid the mouth and be easily fixed to the side of the face, thus avoiding interference with the patient's normal life and diet.

[0011] by Figure 1 The directions of up, down, left, right, front, and back in this embodiment are defined, with the end closer to the nasal cavity defined as the inner end of this embodiment, and the other end as the outer end of this embodiment.
[0012] As shown in the figure, this embodiment includes a breathing tube 1, which consists of a curved section 2 and a straight section 3 that are interconnected. The straight section 3 is connected to the outer port, and the curved section 2 is connected to the inner port. In use, the patient's nasal cavity can communicate with the outside world through the breathing tube 1. The straight section 2 and the curved section 3 form an angle between 100° and 165°. In this embodiment, the angle between the straight section 2 and the curved section 3 is set to 130°, so that the curvature angle of the breathing tube 1 matches the nasal cavity, thus preventing the breathing tube 1 from changing direction due to pressure, thereby obstructing ventilation.
[0013] A balloon 4 is mounted on the curved section 2. The balloon 4 is fixed to the circumferential surface of the curved section 2 by adhesive bonding, and the balloon 4 is not connected to the curved section 2. The upper and lower end faces of the balloon 4 are arched upwards, matching the curved structure of the curved section 2, so that the balloon 4 is evenly distributed on the curved section 2, which can avoid the phenomenon of pressure compression of the breathing tube 1 due to uneven pressure distribution inside the balloon 4 during use. The inner port of the breathing tube 1 extends out of the balloon 4 and is provided with a guide head 9. The outer surface of the inner end of the guide head 9 is smooth and arc-shaped, which can avoid damage to the inner wall of the nasal cavity when inserted into the nasal cavity. In this embodiment, a metal insert or barium sulfate can be provided at the inner end of the guide head 9, so that the guide head 9 is radiopaque and its position can be observed by X-ray during use.
[0014] A balloon inflation tube 5 is provided in the breathing tube 1. The balloon inflation tube 5 includes an inner tube 6, which is disposed in the wall of the breathing tube 1 and exits integrally with the breathing tube 1. The inner end of the inner tube 6 extends to the inner cavity of the balloon 4 and communicates with the balloon 4 through the first inflation port 8. The tube outside the breathing tube 1 is the outer tube 7, which is located on the right side of the breathing tube 1 and is fixed to the circumference of the breathing tube 1 by adhesive. The outer tube 7 communicates with the inner tube 6. In use, the outer tube 7 can deliver a medium to the balloon 2 to inflate the balloon 2. In this embodiment, the outer tube 7 forms an angle with the breathing tube 1 in the top view, with the angle being between 30° and 70°. In this embodiment, the angle between the outer tube 7 and the breathing tube 1 is 45°. After the balloon 4 is placed in the nasal cavity, the outer tube 7 can avoid the mouth, making it easy to fix on the side of the face and avoiding interference with the patient's normal life and diet.
[0015] A one-way valve 11 is provided on the outside of the balloon inflation channel 5. The inner end of the one-way valve 11 is connected to the balloon inflation channel 5. In this embodiment, the one-way valve 11 adopts existing equipment. It can inject or aspirate the medium by inserting a syringe and automatically closes when the syringe is pulled out. It will not be described in detail here. An indicator balloon 10 is provided between the one-way valve 11 and the balloon inflation channel 5. The inner end of the indicator balloon 10 is fixed to the circumferential surface of the balloon inflation channel 5 by adhesive, and the connection between its left and right ends is sealed. The indicator balloon 10 is connected to the balloon inflation channel 5 and the one-way valve 11. When the medium is delivered to the balloon inflation channel 5 through the one-way valve 11, the pressure status of the balloon 4 can be roughly judged by the indicator balloon 10, and it can be judged whether the balloon 4 has a significant pressure drop in a short period of time, so as to avoid the phenomenon of leakage and detachment of the balloon 4.
[0016] In this embodiment, the endoscope is first inserted through the lumen of the breathing tube 1 and exits through the guide head 9, straightening the breathing tube 1. Hemostatic material is then applied to the surface of the balloon 2. After this, the balloon 2 is placed into the patient's nasal cavity. During insertion, the bleeding point can be observed through the endoscope, and the balloon can be moved to the bleeding point. If there is continuous bleeding, the endoscope can be removed first, and the nasal cavity can be flushed and drained through the breathing tube 1 to dilute and remove the blood, exposing the bleeding point. Then, the endoscope is reinserted, and the balloon is moved to the bleeding point. After the balloon is in place, the endoscope is withdrawn. A syringe is then inserted into the one-way valve 11, and water or air is injected to inflate the balloon 4 for compression hemostasis. During injection, the status of the balloon 4 can be judged by the indicator balloon 10. After the balloon 4 inflates, the syringe is removed, completing the compression hemostasis of the nasal cavity.
