Technical Field

[0001] The present invention relates to the technical field of bedridden care water supply, and more specifically, to a multi-diameter adaptable water supply system for bedridden care and a suction-driven deformation flow rate control method. Background Art

[0002] In the daily care work of bedridden patients, ensuring that patients can safely and conveniently intake water is a basic and crucial task. However, the existing water supply systems have many limitations in design and are difficult to fully meet the special needs of bedridden patients, which are specifically reflected in the following aspects:

[0003] An ordinary mineral water bottle needs to tilt the bottle body to discharge water, which cannot be operated when the patient lies flat; the straw of a traditional straw cup is not long enough and has no fixing device, so it is easy to shift and cause water leakage; the existing straw cup relies on the patient's suction to adjust the flow rate, but patients with weak swallowing ability are prone to choking; although the medical water feeder can adjust the flow rate, its structure is complex and the cost is high. Therefore, we make improvements on this and propose a multi-diameter adaptable water supply system for bedridden care and a suction-driven deformation flow rate control method. Summary of the Invention

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] Example 1, please refer to Figures 1-3, A multi - caliber adaptable water supply system for bedridden care, including a bottle - mouth connector 1. The bottle - mouth connector 1 is used to adapt to the standard mineral water bottle mouth. The bottle - mouth connector 1 is connected to a flow regulating valve 2. The flow regulating valve 2 is connected to an adapter, and the adapter is connected to a hose 4. A fixing member is also provided on the hose 4, and the fixing member is used to fix the hose 4 at the hospital bed; The fixing member includes a fixing clip 7 clamped on the hose 4. A magnet 701 is connected to the fixing clip 7. The water is transported to the patient through the hose 4, and the patient can complete the drinking operation independently without relying on the nursing staff, greatly improving the patient's autonomy and quality of life; The hose 4 can be made of food - grade or medical - grade silicone. The hose 4 made of food - grade or medical - grade silicone not only meets the health and safety standards to ensure the patient's drinking water health, but also has good flexibility, can be bent at will, and can be flexibly adjusted according to the hospital bed environment and the patient's body position to adapt to a variety of complex scenarios;

[0033] The fixing clip 7 with the magnet 701 can be conveniently and firmly adsorbed on the metal guardrail of the hospital bed, fixing the hose 4 at a suitable position within the patient's reach, enabling the patient to drink water easily at any time without calling the nursing staff. This enhances the patient's sense of control over their own life, reduces the psychological pressure and sense of inferiority caused by relying on others, helps the patient maintain a positive attitude, and promotes physical recovery.

[0034] Furthermore, the bottle - mouth connector 1 includes an imitation bottle cap 101. The imitation bottle cap 101 is used to adapt to the standard mineral water bottle mouth. A connecting pipe 102 is fixedly connected to the imitation bottle cap 101. Threaded interfaces 201 are provided at both ends of the flow regulating valve 2, and one of the threaded interfaces 201 is connected to the connecting pipe 102. A sealing gasket 103 is also provided on the imitation bottle cap 101. The sealing gasket 103 can be made of food - grade or medical - grade silicone. Through the sealing gasket 103, the sealing performance of the connection between the imitation bottle cap 101 and the mineral water bottle mouth can be improved; It is not easy to leak when inverted. This not only reduces problems such as the hospital bed being soaked and items being contaminated caused by leakage, keeps the hospital bed and the surrounding environment clean and dry, but also prevents external pollutants such as dust and bacteria from entering the bottle and contaminating the water source, ensuring the health and safety of the patient's drinking water;

[0035] The bottle - mouth connector 1 and the flow regulating valve 2 are detachably connected because the bottle - mouth connector 1 with different types of imitation bottle caps 101 can be replaced to adapt to mineral water bottles of different calibers, achieving multi - caliber adaptation.

[0036] Furthermore, the adapter includes a connecting elbow 3. One end of the connecting elbow 3 is fixedly connected to a threaded joint 302, and the threaded joint 302 is threadedly connected to the other threaded interface 201; Adopting the threaded connection method makes the disassembly and assembly operation between the connecting elbow 3 and the flow regulating valve 2 very convenient. Nursing staff or maintenance personnel can easily complete the disassembly and installation work, facilitating the cleaning or replacement of the corresponding components.

[0037] Further, one end of the connecting elbow 3 away from the threaded joint 302 is fixedly connected with a sleeve 301. The hose 4 is sleeved on the outer surface of the sleeve 301. The connection between the hose 4 and the connecting elbow 3 can be realized through the sleeve 301. The connection method of the hose 4 sleeved on the sleeve 301 is simple and easy to implement. During installation, only need to accurately sleeve the hose 4 on the outer surface of the sleeve 301, without complex operations and professional skills, reducing the installation difficulty.

[0038] Further, a check valve is arranged inside the sleeve 301, and the check valve conducts unidirectionally towards the hose 4 direction. The check valve can reduce the pollution of water backflow; reducing the risk of patients getting diseases caused by drinking polluted water and ensuring the physical health of patients.

[0039] Further, one end of the hose 4 away from the sleeve 301 is connected with a duckbill valve 5. The duckbill valve 5 can be made of silicone material. Under normal conditions, the valve orifice of the duckbill valve 5 is closed. When the patient bites, the valve orifice of the duckbill valve 5 is pressed to open, and it closes by elastic reset after stopping biting, preventing liquid leakage;

[0040] The unique design of the duckbill valve 5 brings an excellent user experience to patients, and at the same time keeps the hospital bed and the surrounding environment clean. The duckbill valve 5 made of silicone material has good elasticity and comfort. Patients will not feel discomfort when biting, and can complete the drinking action easily and naturally; its characteristic that the valve orifice is closed under normal conditions, is pressed to open when the patient bites, and quickly resets and closes by elasticity after stopping biting realizes the precise control of water flow; patients can easily open the water flow with a simple biting action and drink water as needed, without the need to squeeze hard or perform other complex operations, especially suitable for bedridden patients with weak hand strength or inconvenient movement. In addition, the duckbill valve 5 has a certain anti-choking function. Patients can control the biting force according to their own situation, reducing choking caused by too large water flow, and further ensuring the drinking safety and comfort of patients.

[0041] Just screw the bottle mouth of the mineral water bottle together with the imitation bottle cap 101 and then invert it. The fixing clip 7 clamps the hose 4 and adsorbs on the guardrail of the hospital bed through the magnet 701. The duckbill valve 5 extends near the patient's mouth, and the patient can bite the duckbill valve 5 at any time.

[0042] Embodiment 2 further optimizes the multi-caliber adaptable bedridden care water supply system provided in Embodiment 1. Specifically, the flow regulating valve 2 is a mechanical hand-twisting valve, and the user manually rotates it to adjust the flow rate. This application is placed in the area that can be reached by the patient's hand at the bedside table, and the patient's hand can move normally. When drinking, the patient can manually rotate it to adjust the flow rate;

[0043] The mechanical hand-twist valve has a simple structure and is easy to operate. Patients can easily adjust the flow rate by manually turning it, without complex operation procedures and professional knowledge. The mechanical hand-twist valve does not rely on external energy sources such as electricity and has high reliability and stability. It can still be used normally even in special situations such as power outages, ensuring that patients can always adjust the drinking water flow rate and obtain appropriate drinking water.

[0044] Example 3 further optimizes the multi-diameter adaptable water supply system for bedridden care provided in Example 1. Specifically, the flow control valve 2 is a solenoid valve. The flow control valve 2 is connected to a microcontroller, and the microcontroller is connected to a pressure sensor 6. The pressure sensor 6 is coated inside the duckbill valve 5. The pressure sensor 6 is not located inside the cavity of the duckbill valve 5 but is coated inside the material of the duckbill valve 5. When the duckbill valve 5 is bitten, the pressure sensor 6 detects the pressure and transmits it to the microcontroller, and the microcontroller controls the opening degree of the solenoid valve to adjust the flow rate. If the patient bites gently, the opening of the solenoid valve is small and the water flow rate is small. If the patient bites hard, the opening of the solenoid valve is large and the water flow rate is large, thus realizing intelligent control.

[0045] Example 4 further optimizes the multi-diameter adaptable water supply system for bedridden care provided in the above embodiments. Specifically, the imitation bottle cap 101 is connected to a support structure 8. The support structure 8 includes a support ring 801. One side of the top of the support ring 801 is provided with a first support plate 802. The top of the first support plate 802 is fixedly installed with a second support plate 803. The imitation bottle cap 101 is fixed in the middle of the second support plate 803. A third support plate 804 is fixedly installed on the first support plate 802. The top end of the third support plate 804 is fixedly connected to a limiting ring 805 located above the second support plate 803. The support ring 801, the first support plate 802, and the second support plate 803 cooperate with each other to support the mineral water bottle for easy inversion, while the limiting ring 805 and the third support plate 804 cooperate to limit the body of the mineral water bottle to improve its stability.

[0046] Example 5, a suction-driven deformation flow rate control method, uses a multi-diameter adaptable water supply system for bedridden care, including the following steps:

[0047] Install the bottle mouth connector 1 on the mineral water bottle and invert it. Use a fixing piece to fix the end of the hose 4 near the patient's mouth. Set the water flow rate through the flow control valve 2, and the patient can drink through the hose 4.

[0048] Specifically, fit the imitation bottle cap 101 with the sealing gasket 103 and screw it tightly onto the mineral water bottle mouth to ensure that there is no liquid leakage between the bottle mouth connector 1 and the bottle mouth; connect the bottle mouth connector 1 to the threaded interface 201 of the flow regulating valve 2 through the connecting pipe 102 to form a closed water circuit; invert the installed mineral water bottle and stabilize the bottle body through the limiting ring 805 and the support ring 801 of the support structure 8 to prevent it from tipping over; use the fixing clip 7 to clamp the end of the hose 4 and adsorb it to the hospital bed railing through the magnet 701 to ensure that the end of the hose 4 is suspended within the range of 5-10 cm from the patient's mouth;

[0049] If the flow regulating valve 2 is a mechanical hand-twist valve, the patient or caregiver can adjust the opening degree by rotating the valve to achieve a rough adjustment of the water flow rate;

[0050] If the flow regulating valve 2 is a solenoid valve, when the patient gently bites or heavily presses the duckbill valve 5, the pressure sensor 6 inside its material detects the bite force signal, and the microcontroller dynamically adjusts the opening degree of the solenoid valve according to the preset threshold to achieve adaptive control of the flow rate;

[0051] The patient triggers the water flow by biting the duckbill valve 5, and the valve opening elastically closes after stopping biting to prevent liquid dripping.
