Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a gel balloon nasal plug for hemostasis. Background Technology

[0002] Currently, commercially available gel-filled nasal plugs for hemostasis mainly consist of an inflatable bladder and a hemostatic gauze strip wrapped around its surface. The surface hemostatic gauze strip forms a gel upon contact with blood or bodily fluids, which can be applied to the wound to stop bleeding, moisturize, and lubricate. The internal bladder is designed to fit the structure of the human nasal cavity, effectively compressing the bleeding site. It is widely used clinically for stopping nasal bleeding and for postoperative hemostasis after nasal and sinus surgeries.

[0003] However, existing balloon-type nasal plugs for hemostasis have significant drawbacks: because no airway is provided at the balloon, relying solely on a single balloon structure, when the balloon is inflated and opened, it can easily completely block the patient's nasal cavity, preventing the patient from breathing through the nasal cavity. This not only causes severe discomfort for the patient but may also lead to the risk of suffocation in severe cases, affecting the patient's treatment experience and life safety. In view of this, we propose a gel-type balloon-type nasal plug for hemostasis. Summary of the Invention

[0004] The purpose of this invention is to provide a gel balloon nasal plug for hemostasis, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gel-filled balloon nasal plug for hemostasis, comprising an inflatable balloon, a hemostatic gel mesh covering its surface, and a rigid ventilation tube disposed at the inflatable balloon. The rigid ventilation tube is divided into an inner layer and an outer layer, the inner layer being movable relative to the outer layer. The front end of the rigid ventilation tube is close to the air inlet end of the inflatable balloon, the outer side of the outer layer is wrapped with the hemostatic gel mesh, and the rigid ventilation tube, the inflatable balloon, and the hemostatic gel mesh are fixedly connected by an elastic element.

[0006] Optionally, the end of the rigid ventilation duct has an upper arc-shaped structure.

[0007] Optionally, the elastic element is a rubber band or other elastic fastener.

[0008] Optionally, the inner and outer layers of the rigid ventilation duct are in a sliding fit, and the inner layer can be completely pulled out to the outside of the outer layer for cleaning.

[0009] Optionally, the inner diameter of the rigid ventilation tube meets the gas flow requirements for normal breathing in the human nasal cavity.

[0010] Optionally, the curvature of the upper arc-shaped structure is adapted to the internal contour of the human nasal cavity.

[0011] Optionally, the end of the inflatable airbag is provided with an air port for inflation to compress and stop bleeding and for removal after deflation.

[0012] Compared with the prior art, the present invention provides a gel balloon nasal plug for hemostasis, which has the following beneficial effects: 1. This gel-filled nasal plug for hemostasis, by adding a rigid air tube to the inflatable nasal bag, ensures that the inflatable nasal bag will not completely block the nasal cavity after inflation. Patients can breathe normally through the air tube, which effectively reduces the discomfort caused by the inability to breathe through the nasal cavity, reduces the risk of suffocation, and improves the safety and comfort of the treatment process.

[0013] 2. This gel-filled nasal plug for hemostasis features a rigid ventilation tube with a removable inner layer that separates from the outer layer. When the rigid ventilation tube is blocked by a foreign object in the nasal cavity, the inner layer can be easily removed for cleaning. After cleaning, it can be reinserted to restore ventilation. The operation is simple and convenient, and there is no need to disassemble the entire hemostatic nasal plug, ensuring the continuity of the hemostasis process.

[0014] 3. The gel-filled nasal plug with a rigid air tube has an upper arc-shaped end that conforms to the shape of the human nasal cavity, avoiding uneven fit between the tube and the nasal cavity wall. For example, the upper end of the rigid air tube may touch the nasal cavity wall while the lower end is far from it, further improving the device's adaptability to the human nasal cavity and reducing irritation to the nasal mucosa.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] according to Figures 1-3As shown, this invention proposes a gel-filled balloon nasal plug for hemostasis, comprising an inflatable balloon 1, a hemostatic gel gauze 2, and a rigid ventilation tube 3. The inflatable balloon 1 is made of medical-grade elastic material, conforming to the structure of the human nasal cavity. An air port 5 is provided at the end of the inflatable balloon 1 for inflation to compress and stop bleeding, and for removal after deflation. The hemostatic gel gauze 2 is made of existing medical hemostatic gauze material, and the hemostatic gel gauze 2 wraps around the outer layer 32 of the inflatable balloon 1 and the rigid ventilation tube 3.

[0019] In this embodiment, the rigid ventilation tube 3 is made of medical-grade rigid material and consists of an inner layer 31 and an outer layer 32. The inner layer 31 and the outer layer 32 are in a sliding fit, and the inner layer 31 can be completely withdrawn outside the outer layer 32. The front end of the tube is close to the air inlet of the inflatable cuff 1. The rigid ventilation tube 3, the inflatable cuff 1, and the hemostatic gel gauze 2 are fixedly connected by an elastic element 4 to ensure a stable connection without affecting the inflation of the inflatable cuff 1. The end of the tube has an upper arc-shaped structure, and its curvature is designed according to the average contour of the human nasal cavity to achieve a good fit with the nasal cavity wall. The inner diameter of the rigid ventilation tube 3 is set to 3-5mm to meet the gas flow requirements of normal nasal breathing.

[0020] As one application of this embodiment: With the inflatable cuff 1 of the hemostatic nasal plug in its uninflated state, slowly insert it into the corresponding position in the patient's nasal cavity where the bleeding site is located. Inflate the cuff 1 through the air inlet 5 until it expands and provides stable pressure to the bleeding site. At this point, the hemostatic gel gauze 2 comes into contact with the wound and begins to exert its hemostatic and moisturizing effects. Simultaneously, the rigid ventilation tube 3 remains unobstructed, allowing the patient to breathe normally through the tube. If ventilation is obstructed during use, the inner layer 31 can be removed from the outer layer 32, any obstructions removed from the inner layer 31, and then reinserted into the outer layer 32 to restore ventilation. After hemostasis is achieved, deflate the air supply through the air inlet 5. Once the inflatable cuff 1 has contracted, slowly remove the hemostatic nasal plug from the nasal cavity.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
