Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a gradually leaking nasal packing water bag. Background Technology

[0002] Endoscopic nasal surgery has become a mainstream procedure in rhinology due to its clear visualization, precision, and minimally invasive nature. However, it often leaves behind wounds that cannot be sutured, posing a challenge in hemostasis. The primary solution is nasal packing. Current packing materials generally include non-absorbable materials such as petroleum jelly gauze, and absorbable materials such as calcium alginate and nanofiber cotton.

[0003] Inserting and removing materials into the nasal cavity can cause significant trauma. While expandable sponges and similar packing materials have a small volume when inserted into the nasal cavity and expand upon absorbing water, they still present challenges. Removal can be painful, and the sudden drop in pressure can cause secondary bleeding. Furthermore, re-insertion of expandable sponges can be even more painful. Absorbent cotton and gelatin sponges can gradually absorb and dissolve over time, but they generally suffer from insufficient pressure, uncontrollable dissolution time, and high cost.

[0004] Inflatable water-filled balloons are widely used for nasal packing due to their advantages such as minimal pain during insertion and removal and sufficient pressure.

[0005] The existing equipment has the following drawbacks: the water bag is too smooth and is easy to shift in the nasal cavity, or even fall out of the posterior or anterior nasal cavity. In particular, falling out of the posterior nasal cavity may cause serious complications such as foreign body obstruction of the throat and suffocation. Also, single-use extraction can easily lead to a sharp drop in pressure and rebound bleeding.

[0006] Therefore, this application proposes a gradually leaking nasal packing water bag to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a gradually leaking nasal packing water-filled balloon to solve the problems of the above-mentioned water-filled balloons being too smooth, easily shifting in the nasal cavity, or even falling out of the posterior or anterior nasal cavity. In particular, falling out of the posterior nasal cavity may cause serious complications such as foreign body obstruction of the throat leading to suffocation, and the problem that single-time removal can easily lead to a sharp drop in pressure and rebound bleeding.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a gradually leaking nasal packing water bag, comprising a water bag for compressing the nasal cavity, and further comprising:

[0009] A liquid storage device is disposed on one side of the water bladder and communicates with the water bladder;

[0010] A regulating valve is provided between the water bladder and the liquid storage device to regulate the rate at which liquid flows out of the water bladder;

[0011] An injection tube is located on one side of the water bladder and is used to supply water into the interior of the water bladder.

[0012] In some embodiments of this utility model, the liquid storage device includes a liquid sac connected to the regulating valve.

[0013] In some embodiments of this utility model, the liquid storage device includes a liquid storage pipe connected to the regulating valve.

[0014] In some embodiments of this utility model, the liquid storage tube is a hollow cylinder with scale lines on its surface.

[0015] In some embodiments of this utility model, a flexible tube valve is provided on the side of the injection tube away from the water bladder.

[0016] In some embodiments of this utility model, a connecting end is provided on one side of the water bladder, and an injection port connected to the regulating valve is provided on the connecting end. A drain pipe connected to the injection pipe is provided at a position below the injection port on the connecting end.

[0017] In some embodiments of this utility model, a nasal airway is provided at the lower end of the connecting end.

[0018] In some embodiments of this utility model, a filter cover is provided on one side of the nasal airway located inside the nasal cavity.

[0019] In some embodiments of this utility model, the surface of the water bladder is provided with anti-slip grooves at intervals.

[0020] In some embodiments of this utility model, the volume of the water bladder is 25-35 mL.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The regulating valve of this invention is a gradually leaking valve, which allows the liquid in the nasal pack to slowly flow from the nasal pack into the reservoir. The nasal pack can gradually shrink to adapt to the physiological process of gradual edema of the surgical area mucosa. The edematous tissue can self-fill and stop bleeding. As the pack gradually shrinks until it falls off on its own, the damage to the nasal mucosa is minimized, avoiding secondary bleeding. The reservoir collects the exudate from the pack through the gradually leaking valve. While preventing the pack from falling off the posterior nasal cavity, the pressure on the nasal ala is evenly distributed, avoiding pressure sores. It can precisely control the rate of liquid outflow from the pack, thereby achieving precise compression of the nasal cavity. This not only improves the treatment effect but also greatly reduces the patient's discomfort. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figure 1-7 This utility model provides a technical solution: a gradually leaking nasal packing water bag, including a water bag 1 for compressing the nasal cavity, and further including:

[0047] Liquid storage device 2 is located on one side of water bladder 1 and is connected to water bladder 1;

[0048] A regulating valve 21 is installed between the water bladder 1 and the liquid storage device 2 to regulate the rate at which liquid flows out of the water bladder 1.

[0049] The injection tube 4 is located on one side of the water bladder 1 and is used to supply water into the interior of the water bladder 1.

[0050] In this embodiment, see Figure 1-5 ,as well as Figure 7 The liquid storage device (2) includes a liquid sac (202) or a liquid storage tube (201) connected to the regulating valve (21).

[0051] In this embodiment, see Figure 1-5 ,as well as Figure 7 A flexible tube valve 6 is provided on the side of the injection tube 4 away from the water bag 1. The addition of the flexible tube valve 6 allows medical staff to precisely control the speed and amount of water flowing into the water bag 1 through the injection tube 4, ensuring that the pressure applied by the water bag 1 to the nasal cavity is neither too tight nor too loose, thereby achieving the best therapeutic effect. When the syringe 5 injects the set amount of water into the water bag 1, the flexible tube valve 6 is closed, and then the syringe 5 is pulled out from inside the flexible tube valve 6. The flexible tube valve 6 prevents water from the water bag 1 from flowing into the injection tube 4.

[0052] In this embodiment, see Figure 1-5The water bag 1 has a connecting end 11 on one side, and an injection port 112 connected to the regulating valve 21 is provided on the connecting end 11. A drain pipe 111, connected to the injection tube 4, is located below the injection port 112 on the connecting end 11. The injection port 112 and drain pipe 111 provide a designated flow direction for the liquid inside the water bag 1, allowing the water to enter and exit the water bag 1 in an orderly manner, achieving bidirectional control of the water flow. By precisely controlling the inflow and outflow of water, medical staff can adjust the amount of water in the water bag 1, thereby achieving precise control of the pressure on the nasal cavity, improving the treatment efficiency of the patient's nasal cavity, and reducing the patient's pain.

[0053] In this embodiment, see Figure 1-6 The lower end of the connecting end 11 is provided with a nasal airway 3. The nasal airway 3 allows the nasal cavity to still be ventilated while the water bag 1 is packed, relieving the nasal congestion and discomfort caused by postoperative packing.

[0054] In this embodiment, see Figure 6 The nasal airway 3 is equipped with a filter cover 31 on one side inside the nasal cavity. The filter cover 31 has evenly spaced openings, which can effectively prevent tissue, blood clots, etc. inside the nasal cavity from blocking the nasal airway 3, keeping the nasal airway 3 open, keeping the nasal cavity open, and relieving the nasal congestion and discomfort caused by postoperative packing.

[0055] In this embodiment, see Figure 1-5 ,as well as Figure 7 The surface of the water-filled balloon 1 is provided with anti-slip grooves 12 at intervals. The anti-slip grooves 12 are multi-directionally arranged blunt silicone protrusions. The design of the anti-slip grooves 12 can increase the friction of the surface of the water-filled balloon 1, making it fit more tightly to the patient's nasal mucosa. This enhanced fixation helps prevent the water-filled balloon 1 from sliding or shifting during treatment, thereby ensuring the stability and continuity of the treatment effect. At the same time, hemostatic powder can be adsorbed on the anti-slip grooves 12 to promote coagulation.

[0056] In this embodiment, see Figure 1-5 ,as well as Figure 7 The volume of the water sac 1 is 25-35 mL, preferably 25-30 mL or 30-35 mL, and most preferably 30 mL. In a specific embodiment, the volume of the water sac 1 is 30 mL, which is high volume and low pressure, has good ductility, and can avoid uneven local pressure in the nasal cavity after injection, which may aggravate discomfort or even cause mucosal necrosis.

[0057] The specific working process of this utility model:

[0058] See Figure 1-5During operation, the water-filled balloon 1 is first inserted into the patient's nasal cavity. The liquid collection device 2 and the regulating valve 21 are placed outside the nasal cavity. Then, the syringe 5 is inserted into one end of the injection tube 4, and liquid is injected into the water-filled balloon 1 through the injection tube 4. After being injected with water, the water-filled balloon 1 expands inside the nasal cavity, and the expansion can compress and stop bleeding points inside the nasal cavity. After the wound inside the nasal cavity has healed for a period of time, the water-filled balloon 1 needs to be removed from the nasal cavity. At this time, the regulating valve 21 is opened. The regulating valve 21 is a gradual leakage valve, which allows the liquid in the water-filled balloon 1 to slowly flow into the liquid collection device 2, further causing the nasal packing water-filled balloon 1 to gradually shrink, adapting to the physiological process of the gradual edema of the surgical area mucosa. The edematous tissue can also play a role in self-filling and hemostasis. At that time, the packing water-filled balloon 1 gradually shrinks until it falls off on its own, so as to minimize damage to the nasal mucosa and avoid secondary bleeding. The liquid collection device 2 collects the liquid seeping out of the packing water bag 1 through the regulating valve 21. While preventing the water bag 1 from falling out of the posterior nasal cavity, it also ensures that the nasal wing is evenly stressed, avoiding pressure sores. It can also precisely control the speed at which the liquid flows out of the water bag 1, thereby achieving precise pressure on the nasal cavity. This not only improves the treatment effect but also greatly reduces the patient's discomfort.

[0059] Example 1

[0060] See Figure 1-2 ,as well as Figure 5 The fluid storage device 2 includes a fluid storage tube 201 connected to the regulating valve 21. The fluid storage tube 201 is a hollow cylinder with graduated lines on its surface. The shape of the fluid storage tube 201 is fixed, and the graduated lines on its surface provide medical staff with an intuitive reference for the amount of fluid. When adjusting the amount of fluid in the water bag 1, medical staff can accurately judge the amount of fluid in the fluid storage tube 201 according to the graduated lines, thereby achieving precise control of the remaining amount of fluid in the water bag 1. This helps to ensure that the nasal cavity receives appropriate pressure, neither too tight nor too loose, improving the treatment effect and patient comfort.

[0061] Example 2

[0062] The difference between Example 2 and Example 1 is that, see reference... Figure 7 The fluid storage device 2 includes a fluid sac 202 connected to the regulating valve 21. As part of the fluid storage device 2, the fluid sac 202 is tightly connected to the regulating valve 21. When the regulating valve 21 is opened, the water in the water sac 1 gradually flows into the interior of the fluid sac 202. The fluid sac 202 gradually becomes larger and can be fixed on the outside of the nasal cavity, which can effectively prevent the water sac 1 from falling from the posterior nasal cavity into the throat.
