[0002] According to the "China Stroke Prevention and Control Report (2023)," the number of stroke patients aged 40 and above in my country has reached 12.42 million, and the onset of the disease is becoming increasingly younger. On average, one person experiences a first-time or recurrent stroke every 10 seconds in my country, and one person dies from a stroke every 28 seconds. Among survivors, approximately 75% suffer from hemiplegia, aphasia, and dysphagia as sequelae, and 40% experience severe disability. Dysphagia refers to difficulty swallowing caused by various factors occurring in different parts of the body. This disorder can affect food intake and nutrient absorption, and may also lead to aspiration of food into the trachea, causing aspiration pneumonia. It significantly impacts the maintenance of nutrition, disease recovery, and improvement of quality of life for patients.

[0003] Traditional water cups require patients with swallowing disorders to tilt their heads back and tilt the cup when drinking, which causes the patient's trachea to open. When the cup is tilted, water can easily flow out, causing aspiration and choking. Therefore, there is an urgent need for a water cup that prevents accidental aspiration. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0022] The following reference Figures 1 to 4 This application describes a water cup designed to prevent accidental aspiration, provided according to some embodiments.

[0023] like Figure 2 As shown, an anti-aspiration water cup provided according to some embodiments of this application includes a cup body 1; a connecting hose 3, disposed within the cup body, the connecting hose 3 being made of medical-grade silicone and capable of being bent freely; a gravity ball 31, disposed at the end of the connecting hose 3; a sucking tube 32, disposed at the end of the connecting hose 3 away from the gravity ball 31, the sucking tube 32 contacting the patient's mouth, the sucking tube 32 and the connecting hose 3 being made of medical-grade silicone; a flow regulating valve 4, disposed between the connecting hose 3 and the sucking tube 32, the flow regulating valve 4 being used to regulate the water flow rate; and a handle 5, fixedly disposed on the outside of the cup body 1.

[0024] In this embodiment, the cup body 1 serves as a liquid container for holding drinking water. When the patient drinks, the cup body 1 is tilted to a suitable angle according to the patient's posture. At this time, the gravity ball 31 moves with the liquid flow to ensure that the liquid can be sucked out. The connecting hose 3 bends with the movement of the gravity ball 31. The patient's lips touch the end of the sucking tube 32 and gently suck, generating negative pressure to draw the liquid out through the connecting hose 3. This method does not require the patient to tilt their head back at an excessive angle, thereby reducing the risk of choking. At the same time, the flow rate can be adjusted according to the patient's swallowing ability by adjusting the flow regulating valve 4, thereby controlling the liquid flow rate and preventing the liquid from accidentally entering the trachea due to excessive flow rate. After drinking, the cup is upright, the gravity ball 31 falls back to the bottom of the cup, and the connecting hose 3 automatically resets.

[0025] In some possible embodiments, such as Figure 2 As shown, it also includes: a cup lid 2, which includes an upper cup lid, a lower cup lid, and a rotating shaft. The rotating shaft causes the upper cup lid to rotate relative to the lower cup lid. The lower cup lid is threadedly connected to the cup body 1. A limiting buckle 21 is provided on the lower cup lid. The upper cup lid has a locking block. The limiting buckle 21 cooperates with the locking block.

[0026] In this embodiment, the lower cup lid is threadedly connected to the cup body 1. When the cup lid 2 is closed, the upper cup lid and the lower cup lid are closed, the limiting buckle 21 engages with the locking block, and completely includes and fixes the sucking tube 32, forming a completely closed state to prevent liquid leakage from the cup body 1. When it is necessary to open the cup lid 2, the limiting buckle 21 is pressed to release the limiting of the locking block, so that the upper cup lid rotates and disengages from the lower cup lid through the rotating shaft, rotating to 120° to expose the position of the sucking tube 32. At this time, the patient can drink water freely. By completely covering the outlet of the sucking tube 32 in the closed state, dust, foreign objects or bacteria are prevented from entering, ensuring safety and hygiene.

[0027] In some possible embodiments, such as Figure 2 As shown, it also includes: two limiting blocks 33, which are respectively disposed on the upper cup lid and the lower cup lid. Each limiting block 33 has an arc-shaped groove, and the sucking tube 32 is placed in the arc-shaped groove.

[0028] In this embodiment, the semi-circular structure of the two arc-shaped grooves matches the outer diameter of the sucking tube 32, ensuring that the sucking tube 32 is stably positioned within its arc-shaped grooves when the cup lid 2 is closed, preventing displacement due to shaking or collision, and generating a clamping force on the sucking tube 32 to ensure that it does not shift and prevent liquid leakage, while also improving the protection of the sucking tube 32 and preventing contamination.

[0029] In some possible embodiments, such as Figure 3As shown, the flow regulating valve 4 includes: two connecting blocks 41, which are threadedly connected to the ends of the suction tube 32 and the connecting hose 3, respectively; two blocking blocks 42, which are disposed on the side of each connecting block 41 away from the suction tube 32 and the connecting hose 3; an adjusting block 43, which is rotatably connected to each blocking block 42, and the adjusting block 43 has anti-slip texture on its exterior; and a blocking plate inside each blocking block 42 and the adjusting block 43.

[0030] In this embodiment, the flow regulating valve 4 is threadedly connected to the end of the suction tube 32 and the connecting hose 3 via the connecting block 41 to ensure a tight seal. A baffle plate is distributed inside the baffle block 42 and the regulating block 43. The patient can adjust the flow rate by rotating the regulating block 43 to change the overlap area between the baffle plate and the liquid channel. This design ensures both structural sealing and ease of operation, allowing for flow rate adjustment based on the patient's swallowing difficulty level, preventing the risk of aspiration due to excessive flow. Furthermore, the flow regulating valve 4, threadedly connected to the suction tube 32 and the connecting hose 3 via the connecting block 41, can be disassembled for cleaning, improving safety during use.

[0031] In some possible embodiments, such as Figure 4 As shown, it also includes: an adjustment belt 51, which is set on the handle 5. The adjustment belt 51 includes multiple through holes and limiting blocks, and the limiting blocks are inserted into the corresponding through holes.

[0032] In this embodiment, the length of the adjustment strap 51 is adjusted according to the hand size or gripping habits of different users. Multiple through holes on the adjustment strap 51 cooperate with the limiting block to improve the versatility of the handle 5. The adjustment strap 51 is made of flexible and wear-resistant material, conforms to the curve of the hand, reduces the pressure and discomfort when gripping, and provides stable gripping support for the patient.

[0033] In some possible embodiments, such as Figure 1 As shown, it also includes: a base 6, which is set at the bottom of the cup body 1, and the bottom of the base 6 has an anti-slip material.

[0034] In this embodiment, the base 6 is located at the bottom of the cup body 1. The bottom of the base 6 has an anti-slip material. The high coefficient of friction and surface texture of the anti-slip material ensure that the cup is not easy to slide or shift when placed. When an external force is applied to the cup, the friction between the anti-slip material and the contact surface cancels out the external force and prevents the cup from tipping over.

[0035] In some possible embodiments, such as Figure 1 As shown, it also includes: a temperature-sensitive coating 7, which is uniformly attached to the outside of the cup body 1, and the thickness of the temperature-sensitive coating 7 ranges from 0.1 to 0.3 mm.

[0036] In this embodiment, the temperature-sensitive coating 7 is uniformly attached to the outside of the cup body 1 and closely fits the curved surface of the cup body 1. The thermochromic material in the temperature-sensitive coating 7 is sensitive to temperature. When the temperature of the liquid inside the cup changes, the molecular structure arrangement of the thermochromic material changes, resulting in a color change. The temperature-sensitive coating 7 corresponds to different temperature sensing ranges and is divided into multiple temperature intervals. Each interval corresponds to a different color display state, which helps users quickly judge the liquid temperature and avoid burns or accidentally drinking cold drinks.

[0037] In some possible embodiments, the cup body 1 is a plastic cup.

[0038] In this embodiment, the patient is generally weak and has little strength. The plastic cup body 1 is made of a lightweight material. When the patient drinks water or takes medicine on their own, the lightweight design can reduce the burden on the arm muscles and improve the comfort of use. In addition, the patient is weak and has difficulty moving, and is prone to falls or collisions. If a traditional glass or ceramic cup is broken, it may cause secondary injuries such as cuts or punctures.

[0039] In some possible embodiments, the density of the gravity ball 31 is greater than that of water.

[0040] In this embodiment, the density of the gravity ball 31 is greater than that of water. No matter how the cup is tilted, the gravity ball 31 will sink to the bottom of the cup due to gravity. In the cup, the gravity ball 31 can ensure that the end of the connecting hose 3 is always in contact with the liquid, avoiding the suction of air due to the tilt of the cup body 1, and improving the user's convenience.

[0041] In some possible embodiments, such as Figure 4 As shown, the handle 5 has an anti-slip texture on the outside.

[0042] In this embodiment, the anti-slip texture increases the friction on the surface of the handle 5, reducing the relative slippage between the hand and the handle 5. It is suitable for situations with wet hands, sweaty hands, or weak hand strength. Patients with weak constitutions, children, the elderly, or Parkinson's patients are prone to slipping when holding a water cup, and the anti-slip texture can significantly reduce this risk.

[0043] When using this anti-aspiration water cup, the patient tilts the cup body 1 to a suitable angle according to their body position. Because the gravity ball 31 is denser than water, it always sinks to the bottom of the cup, ensuring that the end of the connecting hose 3 is in contact with the liquid no matter how the cup body 1 is tilted. The patient gently sucks on the straw 32 to create negative pressure, causing the liquid to be drawn out through the connecting hose 3. Drinking is possible without tilting the head back. The gravity ball 31 ensures a continuous supply of liquid, preventing aspiration due to improper body position. Simultaneously, the patient can adjust the liquid flow rate according to the degree of swallowing difficulty by rotating the adjusting block 43 of the flow regulating valve 4 to change the overlap area between the baffle and the liquid channel, thereby achieving precise flow rate control and preventing excessively fast liquid flow. When not using the cup body 1 for drinking, the upper part of the cup... The upper and lower cup lids are locked together by a limiting buckle 21 and a locking block, completely sealing the sucking tube 32. The limiting block 33 and the arc-shaped groove fix the position of the sucking tube 32 to prevent liquid leakage and external contamination. When drinking water, pressing the limiting buckle 21 releases the limiting, allowing the upper cup lid to rotate 120° to expose the sucking tube 32, so the patient can drink directly. At the same time, the length of the adjustment strap 51 can be adjusted according to the size of the patient's hand to improve the stability of the patient's grip. The base 6 with anti-slip material ensures that the cup body 1 is placed stably to prevent it from tipping over due to external force. The temperature-sensitive coating 7 changes color with the temperature of the liquid in the cup, visually indicating the temperature range and preventing burns or accidental drinking of cold drinks.
