Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nasal compression hemostasis balloon. Background Technology

[0002] Nosebleeds are a common clinical emergency, mainly caused by the rupture of blood vessels in the nasal mucosa. Current routine treatment involves nasal packing for hemostasis, with inflatable balloons being widely used. This technique involves inserting an uninflated balloon through the anterior nasal cavity, positioning it, and then injecting air or liquid to inflate it, using physical pressure to close the bleeding point and achieve mechanical hemostasis.

[0003] Existing technologies often use pear-shaped or elliptical balloons with a straight structure when inflated and a smooth surface. When patients breathe, cough, or sneeze, the balloons are prone to displacement or even complete dislodgement, which not only undermines the hemostatic effect but may also scratch the nasal mucosa, causing secondary damage. Furthermore, existing balloons lack drug synergistic function, and relying solely on physical compression is insufficient to accelerate the coagulation process, resulting in low hemostatic efficiency. Utility Model Content

[0004] The purpose of this invention is to design a nasal compression hemostatic balloon that can better adapt to the human nasal cavity, improve hemostasis efficiency when used with medication, and effectively prevent slippage.

[0005] This utility model includes a catheter with an indicator balloon and a one-way valve. The inner end of the catheter is connected to and communicates with a balloon. The balloon includes a cylindrical first balloon and a second balloon. The first balloon and the second balloon are oriented at an angle. An arc-shaped intermediate balloon connects the adjacent ends of the first balloon and the second balloon.

[0006] Furthermore, the outer surface of the first balloon and / or the second balloon is provided with anti-slip protrusions.

[0007] Furthermore, the anti-slip protrusion is at least one protruding ring surrounding the first balloon or the second balloon.

[0008] Furthermore, the protruding ring is wavy.

[0009] Furthermore, the catheter is connected to the side with the high curvature of the intermediate balloon.

[0010] Furthermore, the first and second balloons are of different lengths.

[0011] The beneficial effects of this utility model are: This invention connects the adjacent ends of a cylindrical first balloon and a second balloon at an angle using an arc-shaped intermediate balloon, forming an L-shaped balloon. The first and second balloons have different lengths, allowing selection of the appropriate length based on clinical needs to achieve uniform hemostasis. Multiple wavy protrusions along the length of the outer surfaces of the cylindrical first and second balloons form anti-slip protrusions, with annular grooves between adjacent protrusions. Hemostatic materials can be placed within these grooves. Thus, the anti-slip protrusions effectively prevent balloon displacement or dislodgement, and the annular grooves store hemostatic materials, improving hemostasis efficiency.

[0012] The first and second balloons both have rounded tips made of a soft material to prevent damage to the nasal cavity. The balloons are connected in sequence to an indicator balloon and a one-way valve via catheters. Both the first and indicator balloons can inflate and deflate simultaneously, allowing the status of the balloons inside the nasal cavity to be determined by observing changes in the external indicator balloon.

Detailed Implementation

[0014] Unless otherwise specified, the inner end of this embodiment is defined as the end facing the nasal cavity; the rear end of the first and second balloons in this embodiment is defined as the end that is adjacent to and communicates with the first balloon, and the front end is the opposite end.

[0015] As shown in the figure, this embodiment includes a catheter 1 with an indicator balloon 5 and a one-way valve 6, and a balloon 2 connected to and communicating with the inner end of the catheter 1. One end of the indicator balloon 5 communicates with the balloon 2 through the catheter 1, and the other end of the indicator balloon 5 is fixedly connected to the one-way valve 6 by threads; the one-way valve 6 is a conventional product in the prior art, which can open when the syringe is inserted to inject or aspirate the medium, and automatically close when the syringe is withdrawn.

[0016] Among them, the indicating balloon 5 is communicated with the balloon 2, and can be simultaneously inflated and deflated, so that the state of the balloon 2 in the nasal cavity can be judged by observing the change of the external indicating balloon 5.

[0017] The balloon 2 in this embodiment includes a columnar first balloon 21 and a second balloon 22. The directions of the first balloon 21 and the second balloon 22 form an included angle. The arc-shaped middle balloon 23 connects the adjacent ends of the first balloon 21 and the second balloon 22. The rear ends of the first balloon 21 and the second balloon 22 are connected through the arc-shaped middle balloon 23 to form a balloon 2 with an included angle, so that the balloon 2 is in a shape similar to an L in its natural state; and the catheter 1 communicates with the large curvature side of the arc-shaped middle balloon 23.

[0018] The front ends of the first balloon 21 and the second balloon 22 are both round heads and are made of a relatively soft material, which is easier to enter the nasal cavity and effectively prevents damage to the nasal cavity; anti-slip protrusions 3 are provided on the outer surface of the first balloon 21 and / or the second balloon 22. The anti-slip protrusions 3 are at least one protruding ring 31 surrounding the first balloon 21 and the second balloon 22, and the protruding ring 31 is wavy.

[0019] In this embodiment, anti-slip protrusions 3 formed by three wavy protruding rings 31 are provided on the outer surfaces of the first balloon 21 and the second balloon 22. An annular groove 4 is formed between each adjacent protruding ring 31; the number of protruding rings 31 of the anti-slip protrusions 3 can be set according to the lengths of the first balloon 21 and the second balloon 22 to ensure effective anti-slip. After injecting air or water as a medium into the balloon 2, the balloon 2 bulges to make the first balloon 21 or the second balloon 22 fit against the bleeding part of the nasal cavity inner wall, and effective anti-slip is achieved under the action of the anti-slip protrusions 3 to prevent the balloon 2 from shifting or slipping out and causing secondary damage to the nasal cavity inner wall.

[0020] Among them, a hemostatic material can be coated on the surface of the balloon 2. The annular groove 4 can store the hemostatic material to increase the coating amount, ensure that the hemostatic material can enter the bleeding part, and ensure the coating area to achieve a better hemostatic effect.

[0021] The lengths of the first balloon 21 and the second balloon 22 are different. The lengths L1 and L2 of the first balloon 21 and the second balloon 22 can be set to be equidistant (L1 = L2) or non-equidistant (L1 > L2; L1 < L2), and the length range is between 2 cm and 10 cm. The first balloon 21 or the second balloon 22 with a suitable length is selected according to clinical needs to achieve the purpose of uniform filling and hemostasis.

[0022] In this embodiment, the balloon 2 and part of the catheter 1 need to enter the nasal cavity. The materials used can be relatively soft materials such as silicone rubber, latex, PVC or PU plastic, etc., to ensure safety and prevent damage to the nasal cavity.

[0023] The catheter 1 is connected to the side with the large curvature of the arc-shaped intermediate balloon 23. After the medium is introduced, the intermediate balloon 23 also inflates, and the balloon 2 gradually forms a C-shape to a straight line. Since the front ends of the first balloon 21 and the second balloon 22 are closed, the pressure is greater. Combined with the anti-slip protrusion 3, the wall thickness of the balloon 2 is thickened to a certain extent, resulting in the deformation of the middle of the balloon 2 being slightly greater than that of the two ends. In addition to maximizing the space for compression in the nasal cavity, it also further prevents the balloon 2 from completely dislodging and causing secondary damage to the nasal mucosa when the patient breathes, coughs, or sneezes.

[0024] In this embodiment, the air inside the balloon 2 is first expelled through the one-way valve 6 connected to the syringe, so that the balloon 2 is airless and in a contracted state, making it easy to insert the catheter 1 into the nasal cavity. The front part of the balloon 2 is rounded and soft, so it will not cause damage to the nasal cavity. When the intended placement position is reached, water or air is filled into the one-way valve 6 as a medium to inflate the balloon 2 and achieve the effect of compression hemostasis. After the catheter 1 is placed, it can be attached to the appropriate position on the patient's face with a medical fixation tape, which, together with the anti-slip protrusion 3, further prevents the balloon 2 from falling out due to external pulling.
