Description

Technical Field

[0001] This utility model relates to a hemostatic balloon, and more particularly to a nasal hemostatic balloon. Background Technology

[0002] Nasal bleeding is a common clinical symptom that can be caused by a variety of factors, such as trauma, nasal inflammation, hypertension, and blood disorders. Currently, commonly used methods for stopping nasal bleeding in clinical practice include nasal packing and the use of nasal balloons. Traditional nasal packing typically uses materials such as petroleum jelly gauze. This method is relatively complex, causes significant discomfort and pain for the patient during packing, and can easily lead to rebleeding when the gauze is removed.

[0003] While some existing nasal hemostasis balloons have improved the patient experience to some extent, they still have some problems, such as: patients cannot breathe through the nose after the balloon inflates; the inflation shape of the balloon is not easy to control, making it difficult to apply pressure evenly to the bleeding site, resulting in poor hemostasis; and the balloon does not fit well in the nasal cavity, making it easy to shift and affecting the hemostasis operation.

[0004] Therefore, a nasal hemostatic balloon is provided to meet the needs of patients. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a nasal hemostasis balloon.

[0006] The purpose of this utility model is achieved as follows:

[0007] A nasal hemostasis balloon includes a ventilation tube, on the surface of which a plurality of balloons are installed at equal intervals. The balloons are located on one side of the ventilation tube and expand towards one side of the ventilation tube when inflated. The plurality of balloons are distributed adjacent to each other along the ventilation tube. A miniature air pump is installed at the bottom of the ventilation tube, and an air guide tube is installed at the output end of the miniature air pump. The air guide tube is connected to each balloon assembly in sequence to supply air and inflate it.

[0008] The balloon assembly has a drug-filled pouch attached to its surface, and the drug-filled pouch is filled with hemostatic drugs.

[0009] Furthermore, all corners of the balloon are rounded.

[0010] Furthermore, a connecting tube is provided at the connection between the air delivery tube and the balloon, through which the air delivery tube is connected to the inner cavity of the balloon, and a solenoid valve is installed in the connecting tube.

[0011] Furthermore, anti-slip strips are provided on the upper and lower sides of the balloon sidewall.

[0012] Furthermore, a barrier net is installed at the top of the vent pipe.

[0013] Furthermore, a fixing component is installed on one side of the lower part of the vent pipe.

[0014] Furthermore, a slide rail is installed at the lower part of the vent pipe, a slider is slidably connected to the surface of the slide rail, and the fixing component is installed on the top of the slider.

[0015] Furthermore, the fixing component includes a connecting rod, a clamping body, and fixing protrusions. The connecting rod has an arc-shaped structure, and the connecting rod is disposed on the top surface of the slider. The other end of the connecting rod is fixedly connected to the bottom end of the clamping body. The clamping body has a U-shaped structure, and several fixing protrusions are installed at equal intervals on the inner side of the U-shape at the front end of the clamping body. The fixing protrusions have a semi-cylindrical structure.

[0016] Furthermore, an electromagnet is installed on one side of the slider, which fixes the position of the slider when energized.

[0017] Advantages of this utility model:

[0018] 1. The technical solution of this application, by setting up a ventilator, can keep the nasal cavity open while stopping bleeding, so that the patient can still breathe through the nasal cavity.

[0019] 2.

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0025] This application provides a nasal hemostatic balloon.

[0026] Example 1, such as Figure 1-3 As shown.

[0027] A nasal hemostasis balloon includes a ventilation tube 1, which is a hollow tubular structure. A barrier net 2 is installed at the tip of the ventilation tube 1 to protect the tip and prevent nasal mucus or other debris from entering and causing blockage. The ventilation tube 1 keeps the nasal cavity clear, allowing the patient to breathe through the nose while achieving hemostasis.

[0028] A plurality of balloons 3 are evenly spaced on the surface of the ventilation tube 1. The balloons 3 are located on one side of the ventilation tube 1 and expand towards that side when inflated. The balloons 3 are arranged adjacent to each other along the ventilation tube 1, with rounded corners at each edge. Hemostasis is achieved by compressing the balloons 3 upon inflation. The size of each balloon 3 is adjusted according to the location of the bleeding point and the physiological structure of the nasal cavity to ensure it fits snugly against the nasal mucosa, generating more uniform pressure on the nasal cavity. This results in better hemostasis and reduces the likelihood of displacement that could affect hemostasis.

[0029] A miniature air pump 4 is installed at the bottom of the ventilation tube 1. An air guide tube 5 is installed at the output end of the miniature air pump 4. The air guide tube 5 is connected to each balloon 3 component in sequence to supply air and inflate it. A connecting tube 6 is provided at the connection between the air guide tube 5 and the balloon 3, and a solenoid valve 7 is installed in the connecting tube 6 to connect the air guide tube 5 to the inner cavity of the balloon 3.

[0030] Each balloon 3 is equipped with a miniature sensor to detect the internal pressure, thereby facilitating control of the balloon's inflation and pressure on the nasal cavity. The miniature air pump 4 inflates and deflates each balloon 3 via the air tube 5 and multiple solenoid valves 7, achieving precise control over each balloon. Deflating simply requires the miniature air pump 4 to draw air. Several switches are installed on one side of the ventilation tube 1 to control the inflation and deflation of the balloons 3.

[0031] The balloon 3 has a drug-filled pouch 8 attached to its surface, and the pouch 8 is filled with hemostatic drugs. The surface of the balloon 3 is coated with exosome vesicles containing various growth factors, which can promote rapid repair of ruptured blood vessels and mucous membranes. When the balloon 3 inflates, it ruptures the drug-filled pouch 8, allowing the hemostatic drugs inside to flow out and cover the surface of the balloon 3. Upon contact with the nasal cavity, these drugs act on the bleeding site to achieve hemostasis.

[0032] The balloon 3 has anti-slip strips 9 on its upper and lower sidewalls, respectively. These anti-slip strips 9 are made of hydrophilic gel material. Hydrophilic gel material has the property of swelling and increasing viscosity upon contact with water. When it comes into contact with moisture in the nasal cavity, the gel quickly absorbs water and swells, becoming softer and more adhesive, allowing it to adhere tightly to the nasal mucosa and providing an anti-slip effect. Furthermore, hydrophilic gel is generally made of medical-grade materials, is safe and non-toxic, and has no adverse reactions to human tissue. The anti-slip strips 9 increase overall stability and prevent shaking during hemostasis.

[0033] A fixing component 12 is installed on one side of the lower part of the ventilation tube 1 to fix the ventilation tube 1 and prevent it from shaking during the hemostasis process, which could lead to hemostasis failure.

[0034] A slide rail 10 is installed at the lower part of the ventilation tube 1, and a slider 11 is slidably connected to the surface of the slide rail 10. The fixing component 12 is installed on the top of the slider 11. An electromagnet 13 is installed on one side of the slider 11, which fixes the position of the slider 11 when energized. During fixing, the slider 11 is first moved up and down to adjust the appropriate position so that the fixing component 12 is aligned with the nasal septum.

[0035] The fixing assembly 12 includes a connecting rod 121, a clamping body 122, and fixing protrusions 123. The connecting rod 121 has an arc-shaped structure, and is disposed on the top surface of the slider 11. The other end of the connecting rod 121 is fixedly connected to the bottom end of the clamping body 122. The clamping body 122 has a U-shaped structure, and several fixing protrusions 123 are evenly spaced on the inner side of the U-shape at the front end of the clamping body 122. The fixing protrusions 123 have a semi-cylindrical structure. During fixing, the U-shaped opening of the clamping body 122 is aligned with the nasal septum and pushed in, clamping the clamping body 122 on both sides of the nasal septum. The fixing protrusions 123 increase friction, making the fixation more secure.

[0036] When using this utility model:

[0037] Insert the airway tube into the base of the nose with the balloon attachment side facing upwards. Activate the micro-air pump to inflate each balloon, causing it to expand and fill the nasal cavity. After inflation, adjust the position by moving the slider up and down to align the fixing component with the nasal septum. Then, align the U-shaped opening of the clip with the nasal septum and push it in, securing the clip to both sides of the nasal septum.
