Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an oral spray-type drinking water device. Background Art

[0002] Heart failure (HF) is a serious state and terminal manifestation of various cardiovascular diseases. Volume overload is a very important pathophysiological process in the development of HF and is also the main cause of worsening of the condition and re-hospitalization of HF patients. Volume management to limit fluid intake is one of the important non-drug treatment methods for HF patients and is widely used in clinical practice. Fluid restriction therapy for patients with heart failure refers to limiting their intake of various forms of fluid in clinical practice in order to avoid increasing the burden on the heart. Excessive fluid intake will aggravate the symptoms of HF patients. Most re-hospitalizations of HF patients are mainly related to predisposing factors. Studies have reported that fluid retention is the main predisposing factor for decompensated hospitalization of HF patients, and failure to strictly control diet, including high-salt diet and drinking a lot of water, is an important factor leading to fluid retention. Therefore, it is of great significance for HF patients to start volume management as early as possible, and volume management should be carried out throughout the entire process of patient treatment.

[0003] Foreign studies on the fluid intake of patients with heart failure show that regardless of whether the patient is following a prescription to restrict fluid intake or drinking water freely, their daily fluid intake is less than 2000 ml. HF is an irreversible and difficult to cure disease, and standardized and reasonable drinking water is the key to strengthening patient self-management. At present, for critically ill patients who are unconscious, unable to cooperate, and wearing ventilators, it is impossible to obtain cooperation and communication, and the control of the patient's drinking water temperature and amount is more challenging. Mainly include: ① Patients and medical staff cannot accurately measure the amount of water they drink each time, so they cannot accurately control the daily fluid intake. This may cause patients to consume too much water, increase the burden on the heart, and even cause the condition to worsen. ② HF patients often monitor quantifiable indicators such as weight and urine volume to promptly detect changes in fluid balance in the body. The lack of standardized drinking water records can delay the discovery of these changes and delay the adjustment of treatment plans. ③ HF patients require long-term treatment and management. Without standardized drinking fountains and drinking water records, they may not be able to effectively control fluid intake, thereby increasing the risk of complications. All of the above can cause patients to require more medical resources and care, increase medical expenses and social burdens.

[0004] In addition, after various complex major surgeries in clinical practice, especially digestive system surgeries, patients are often required to fast and drink water after surgery. Patients may face a variety of oral problems. Due to fasting and water abstinence, the mouth lacks sufficient water and nutrients, resulting in reduced secretion of the oral mucosa and dry mouth. Dry oral mucosa increases the risk of infection and oral ulcers. Other oral problems include bad breath, increased oral bacteria, and imbalanced oral pH. The occurrence of these problems is related to reduced oral moisture, weakened oral self-cleaning ability, and bacterial growth in the mouth. For patients who need to fast for a long time, these problems may be more prominent. Long-term water abstinence can lead to oral problems such as atrophy of the oral mucosa and tooth loss. It may also cause symptoms such as malnutrition and dehydration, further aggravating oral problems.

[0005] In order to alleviate the oral problems of patients who fast after surgery, measures such as oral moisturizing, oral care, and dietary adjustments can be taken. Appropriate oral moisturizers and oral sprays can help keep the mouth moist, reduce the risk of infection and oral ulcers, and help maintain oral health. At present, hospitals mostly use wet cotton swabs, wet gauze covering the mouth, water in the mouth, gargle, and increase the frequency of oral care to solve the problems of thirst and chapped lips in patients. However, the above methods cannot enable patients to accurately grasp the amount and time of drinking water, and cannot meet the special needs of patients with heart failure and various patients who need to fast.

[0031] like Figure 1 , Figure 8 As shown, there are two structural schematic diagrams of the oral spray drinking water device of the utility model. It can be seen from the figures that the oral spray drinking water device of the utility model includes: a water storage structure for temporarily storing water provided by an external water supplier; a water spray structure connected to the inner cavity of the water storage structure for spraying water in the form of mist or drops; and a pushing structure connected to the water storage structure and used to spray the water temporarily stored therein through the water spray structure.

[0032] Specifically, Figure 1 , Figure 2 , Figure 8As shown, the water storage structure of the utility model includes: a cylindrical water storage pipe 2; a water source connector 10 vertically arranged on the side wall of the water storage pipe for connecting an external water supply device (not shown in the figure) to allow water to flow into the water storage pipe; and a connecting pipe 9 connecting the water source connector to the outer wall of the water storage pipe. The water storage pipe is a quantitative water storage pipe, and its capacity is 10 ml when it is filled with water, and a scale for marking its content is provided on the outer wall of the water storage pipe (not shown in the figure). The water source connector and the connecting pipe form a stepped cylindrical shape, and the diameter of the water source connector is larger than the diameter of the connecting pipe. The inner wall of the water source connector is provided with a thread for connecting to the external thread at the mouth of a mineral water bottle. After the water source connector is connected to the mineral water bottle, the mineral water bottle is inverted to utilize the effect of gravity to make the water in the mineral water bottle flow to the water storage pipe. In order to allow the water in the mineral water bottle to flow smoothly into the water storage pipe, an exhaust member 11 is provided on the connecting pipe, which is connected to the atmosphere to ensure that the water in the mineral water bottle automatically flows to the water storage pipe by gravity and fills the water storage pipe. The structure of the exhaust member provided on the connecting pipe is the same as the structure of the exhaust member used in the infusion bottle during the infusion process in the prior art, and will not be described in detail here.

[0033] The water spray structure of the utility model includes: a water outlet pipe 1 whose rear end is connected to the front end of a water storage pipe and whose front end is closed; a plurality of micro holes 14 arranged at the front end of the water outlet pipe for spraying water in the form of mist or drops. In addition, it also includes a flow direction control component arranged at the outlet pipe near the connection with the water storage pipe for making the water flow flow in one direction, and the flow direction control component includes a one-way valve plate 13 arranged in the water outlet pipe and a flow limiting plate 12 arranged in the water outlet pipe.

[0034] like Figure 5 As shown, the one-way valve plate 13 of the utility model is arranged at the position where the water outlet pipe is connected to the water storage pipe. It adopts a circular thin plate, the outer periphery of which is fixedly connected to the water outlet pipe, and a cross-shaped opening 15 is opened in the center of the thin plate. The cross-shaped opening can be opened under a certain impact of water flow to allow water to flow through, and is in a closed state to block the water flow when the impact force is insufficient.

[0035] The flow limiting plate of the utility model is arranged at the position where the outlet pipe is connected to the water storage pipe, and is slightly spaced from the one-way valve plate. The flow limiting plate is also a circular plate, and its outer periphery is fixedly connected to the inner wall of the outlet pipe. A plurality of concentric arc holes 16 (three or more) are arranged on the flow limiting plate, and the radius of the inner arc of the arc hole is larger than the radius of the cross opening on the one-way valve plate, so as to block the water through the solid part in the center of the flow limiting plate, and make the water flow to the one-way valve plate through the arc hole. When designing, the arc hole on the flow limiting plate can be opened by the following method: Figure 6 The structure is that three arc holes are opened near the edge of the current limiting plate, or the following is adopted: Figure 7 In the structure shown, three arc-shaped portions are cut out from the outer circumference of the flow limiting plate to form an arc-shaped notch, and the arc-shaped notch and the inner wall of the water outlet pipe form an arc-shaped hole.

[0036] When water is stored in the water storage pipe but the pressure is insufficient to open the cross-shaped opening of the one-way valve plate, the water will be in a relatively static state and will not flow toward the outlet pipe. When the pushing structure provides a certain squeezing force for the water in the water storage pipe so that the cross-shaped opening of the one-way valve plate can be opened, the water will flow toward the one-way valve plate through the arc-shaped hole of the flow-limiting plate, and then spray out in the form of mist or drops through the multiple micropores at the front end of the outlet pipe. During design, the aperture of each micropore can be determined according to needs, so that water can be sprayed out in the form of mist or drops as needed.

[0037] The push structure of the utility model is a piston assembly whose front end is placed in the water storage pipe to push the water flowing into the water storage pipe to the water outlet pipe. The front end of the piston rod of the piston assembly extends into the water storage pipe and has an interference fit with the water storage pipe. When designing, the piston assembly can be used as follows Figure 3 , Figure 4 The structure shown includes a piston rod 4, a piston 3 arranged at the front end of the piston rod, a handle 7 arranged at the rear end of the piston rod, and a sealing member 8 arranged on the piston rod along the axial direction of the piston rod and fixed to the piston as a whole. The outer diameter of the piston is equivalent to the inner diameter of the water storage pipe, and the two are interference fit. The length of the sealing member is equal to the length of the piston rod, and is used to block or open the connecting port between the connecting pipe and the water storage pipe when the piston is pushed. The piston is made of a slightly elastic rubber material, and the sealing member is also made of the same material as the piston. The piston rod is cross-shaped (such as Figure 4 , Fig. 9 As shown, the piston rod shape of the prior art syringe can be referred to), and the radius of the circumscribed circle of the cross can be equal to the radius of the piston (such as Figure 4 As shown), it can also be smaller than the radius of the piston (as shown Fig. 9 As shown), the blocking member is a cylindrical body with a cross section of approximately one-quarter of a circle, which is fixedly mounted on the piston rod and can be made integrally with the piston.

[0038] The piston assembly has the following functions: controlling the connection between the water source connector and the inner cavity of the water storage pipe and pushing the water to spray out from the micropores. Figure 1 , Figure 8 As shown in the state shown in the figure, a connecting passage is formed between the water source connector and the water storage pipe, and water can be supplied through a water supply device (such as an inverted mineral water bottle) connected to the water source connector, and the water flows into the water storage pipe through the passage and fills the water storage pipe. Fig.10The plugging piece can disconnect the flow path between the water source connector and the water storage pipe, forming a closed space in the water storage pipe. The mineral water bottle can be placed forward and removed, or the mineral water bottle can be left. By pushing the piston assembly inward, the water in the water storage pipe with a capacity of 10 ml flows to the water outlet pipe. The piston rod is pushed according to the required amount. The speed and pushing capacity can be determined according to the actual situation, so that the water can be sprayed out through the micropores, so as to spray water into the patient's mouth.

[0039] In addition, the utility model also includes a number detector disposed on the piston assembly for detecting and displaying the number of water spraying times, which includes a counting sensor 5 disposed on the handle 7 of the piston assembly for detecting the number of times the piston assembly is pushed forward and a counting display 6 electrically connected to the counting sensor for displaying the number of times the piston assembly is pushed forward. Both the counting sensor and the counting display can adopt the structure capable of counting and displaying in the prior art, which will not be described in detail here.

[0040] The device of the utility model can calculate the total amount of water consumed by counting the number of times, spray water into the oral cavity, keep the oral cavity moist, and drink water in small amounts and multiple times, which has the effect of limiting the amount of water intake, and can control the amount of water consumed and the drinking time of the patient, meeting the special needs of heart failure patients and various patients who need to fast and improve the treatment effect and quality of life of patients. The device is reasonably designed, simple in manufacturing process, low in cost, suitable for large-scale production, and easy to understand in use. Patients can quickly master the use skills, and it is highly feasible. The entire device is small in size (the water storage tube is about 10 ml), easy to carry, and patients can use it anytime and anywhere, without being restricted by time and place, improving the comfort and safety of patients, so that patients can feel caring care during use.

[0041] In summary, the device of the utility model has the following advantages:

[0042] Save consumption: For patients who are thirsty and have dry mouth due to various factors but cannot drink water, this device can be used by one person only, reducing the use of disposable consumables and alleviating the workload of nursing staff.

[0043] Efficient and safe: Compared with the existing method of using cotton swabs or gauze to moisten the lips, this device can moisten the pharynx that cotton swabs or gauze cannot reach, and can prevent accidental aspiration caused by cotton wool falling off, thereby increasing the frequency of oral care.

[0044] Reduce the incidence of complications such as lung infection due to choking: avoid the risk of patients choking when drinking water, reduce patients' pain, reduce the incidence of complications such as lung infection, reduce the extension of patients' treatment and hospitalization days, and reduce the burden on patients.

[0045] Although the utility model is described in detail above, the utility model is not limited thereto, and technicians in this technical field can make modifications based on the principles of the utility model. Therefore, all kinds of modifications made according to the principles of the utility model should be understood to fall within the protection scope of the utility model.
