Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a ventilated nasal cavity hemostatic device. Background Technology
[0002] In the medical field, nasal bleeding (epistaxis) is a common clinical emergency with significant research and treatment value. Epistaxis is mostly caused by the rupture of blood vessels in the nasal mucosa, especially in dry environments, after trauma, in patients who have undergone septoplasty, and in patients with hypertension, where the incidence is relatively high. The bleeding site is mostly concentrated in the Little's area of the anterior inferior part of the nasal septum, which is recognized by the industry as a prone-to-bleeding area, characterized by a dense and superficial distribution of blood vessels.
[0003] Currently, traditional methods for stopping epistaxis mainly include packing (such as using cotton balls, gauze strips, or expanded sponges) and chemical cauterization. However, traditional Vaseline gauze strips and gelatin sponges have certain limitations in practical applications. Traditional Vaseline gauze strips are difficult to achieve rapid hemostasis when used to stop bleeding. Furthermore, because they rely on pressure to stop bleeding, they often completely obstruct the patient's nasal cavity, preventing normal breathing and causing severe discomfort and pain.

[0006] A ventilated nasal cavity hemostatic device includes a ventilation mechanism, a hemostatic mechanism at the top of the ventilation mechanism, and a limiting mechanism on the outer wall of the hemostatic mechanism.
[0007] The ventilation mechanism includes a connecting pipe with an air inlet at the bottom end and a one-way air valve inside the connecting pipe.
[0008] A further improvement of this utility model is that: a balloon is fixedly connected to the top end of the connecting tube, the balloon is connected to the connecting tube, and a connecting tube is fixedly connected to the top end of the balloon, the connecting tube is connected to the balloon.
[0009] A further improvement of this utility model is that a connector is fixedly connected to the top end of the connecting pipe, and the connector is connected to the connecting pipe.
[0010] A further improvement of the present invention is that the hemostasis mechanism includes a ventilation tube, which is fixedly installed at the end of the connector. The connector is connected to the ventilation tube, and two airbags are fixedly connected to the two ends of the ventilation tube away from the connector.
[0011] A further improvement of this utility model is that: the two airbags are connected to the ventilation tube, the surfaces of the two airbags are uniformly covered with a microporous structure, and a hollow ventilation tube is fixedly connected inside the two airbags.
[0012] A further improvement of this utility model is that: a spiral support structure is fixedly connected inside the hollow vent tube, a gelatin sponge pad is fixedly connected to the surface of the hollow vent tube, the surface of the gelatin sponge pad is covered with multiple through holes, and an end is fixedly connected to the top of the hollow vent tube, the end being connected to the hollow vent tube.
[0013] A further improvement of the present invention is that the limiting mechanism includes a limiting buckle, the limiting buckle is snapped onto the outer wall of the hollow vent pipe, the number of the limiting buckles is two, and the inner walls of the two limiting buckles are fixedly connected with a transverse limiting rod.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] This invention provides a ventilated nasal cavity hemostatic device. It comprises a ventilation mechanism consisting of a connecting tube, an air inlet, a one-way valve, a balloon, a connecting tube, and a connector; and a hemostatic mechanism consisting of a ventilation tube, a balloon, a gelatin sponge pad, a spiral support structure, a through hole, an end cap, a microporous structure, and a hollow ventilation tube. These two mechanisms work together to enable rapid hemostasis, rapid absorption of blood and coagulation, and optimized airway access. When needed, simply open the one-way valve to allow air to enter through the air inlet, thereby allowing air to flow through the ventilation tube. The air cuff is inflated, and then the air cuff can evenly compress the nasal mucosa to achieve physical hemostasis. At the same time, the surface of the air cuff is covered with a microporous structure that can promote local blood adsorption. Meanwhile, the hollow air tube that enters the patient's nasal cavity has a biodegradable gelatin sponge pad on its surface. The pores on the surface of the gelatin sponge pad quickly absorb blood and coagulate it. At the same time, the hollow air tube is equipped with a spiral support structure that can maintain the nasal ventilation volume (10-15L / min) and prevent collapse. Combined with the air permeability of the gelatin sponge pad (porosity ≥85%), the risk of mucosal hypoxia is reduced. Attached Figure Description

[0020] Example 1
[0021] like Figure 1-2 As shown, this utility model provides a nasal cavity hemostatic device, including a ventilation mechanism 1, a hemostatic mechanism 2 at the top of the ventilation mechanism 1, a limiting mechanism 3 on the outer wall of the hemostatic mechanism 2, a connecting tube 11 with an air inlet 12 at the bottom end, a one-way valve 13 inside the connecting tube 11, a balloon 14 fixedly connected to the top of the connecting tube 11, the balloon 14 communicating with the connecting tube 11, a connecting tube 15 fixedly connected to the top of the balloon 14, the connecting tube 15 communicating with the balloon 14, a connector 16 fixedly connected to the top of the connecting tube 15, the connector 16 communicating with the connecting tube 15, and a ventilation tube 21 fixedly installed at the end of the connector 16, the connector 16 communicating with the ventilation tube 21. Two airbags 22 are fixedly connected to the two ends of the tube 21 away from the connector 16. The two airbags 22 are connected to the ventilation tube 21. The surface of the two airbags 22 is uniformly covered with a microporous structure 27. A hollow ventilation tube 28 is fixedly connected inside the two airbags 22. A spiral support structure 24 is fixedly connected inside the hollow ventilation tube 28. A gelatin sponge pad 23 is fixedly connected to the surface of the hollow ventilation tube 28. The surface of the gelatin sponge pad 23 is covered with multiple through holes 25. An end 26 is fixedly connected to the top of the hollow ventilation tube 28. The end 26 is connected to the hollow ventilation tube 28. The limiting mechanism 3 includes a limiting buckle 32. The limiting buckle 32 is snapped onto the outer wall of the hollow ventilation tube 28. There are two limiting buckles 32. A transverse limiting rod 31 is fixedly connected to the inner wall of the two limiting buckles 32.
[0022] In this embodiment, by setting up a ventilation mechanism 1 consisting of a connecting tube 11, an air inlet 12, a one-way valve 13, a balloon 14, a connecting tube 15, and a connector 16, and a hemostasis mechanism 2 consisting of a ventilation tube 21, an air balloon 22, a gelatin sponge pad 23, a spiral support structure 24, a through hole 25, an end cap 26, a microporous structure 27, and a hollow ventilation tube 28, the two work together to enable the patient to quickly stop bleeding, rapidly absorb blood and coagulate, and optimize the airway. When needed, simply open the one-way valve 13 to allow air to enter the air inlet 12, thereby allowing the ventilation tube 21 to... Inflating the cuff 22 allows it to evenly compress the nasal mucosa, achieving physical hemostasis. Simultaneously, the surface of the cuff 22 is covered with a microporous structure 27, which promotes local blood absorption. Meanwhile, the hollow ventilation tube 28, which enters the patient's nasal cavity, has a biodegradable gelatin sponge pad 23 embedded in its surface. The pores 25 on the surface of the gelatin sponge pad 23 quickly absorb blood and promote coagulation. At the same time, the hollow ventilation tube 28 has a spiral support structure 24 inside, which can maintain nasal ventilation (10-15 L / min) while preventing collapse. Combined with the air permeability (porosity ≥85%) of the gelatin sponge pad 23, the risk of mucosal hypoxia is reduced.
[0023] The working principle of this nasal vasodilator will be explained in detail below.
[0024] like Figure 1-2 As shown, during use, first open the one-way air valve 13 to allow air to enter the air inlet 12, which in turn allows the air tube 21 to inflate the cuff 22. The cuff 22 can then evenly compress the nasal mucosa to achieve physical hemostasis. At the same time, the surface of the cuff 22 is covered with a microporous structure 27, which can promote local blood adsorption. Then, the hollow air tube 28 that enters the patient's nasal cavity has a biodegradable gelatin sponge pad 23 built into its surface. The through holes 25 on the surface of the gelatin sponge pad 23 quickly absorb blood and coagulate it. Meanwhile, the hollow air tube 28 is equipped with a spiral support structure 24, which can maintain the nasal ventilation volume (10-15L / min) and prevent collapse. Combined with the air permeability (porosity ≥85%) of the gelatin sponge pad 23, the risk of mucosal hypoxia is reduced.
