Description

Technical Field

[0001] This invention relates to the field of fluid delivery devices for the human body, and more specifically, to a device for postoperative dry mouth care for oral patients. Background Art

[0002] Anesthesia is a pre-operative step in surgery. Commonly used anesthetic drugs include atropine. After the use of anesthetic drugs, patients often experience dry mouth. Modern medical research shows that the mechanism of this phenomenon is that anesthetic drugs can reduce saliva secretion and glandular secretion, leading to dryness of the oral mucosa. In addition, some anesthetic drugs may also affect the water regulation mechanism in the central nervous system, further increasing the feeling of thirst. Secondly, surgical procedures such as intubation will lead to the use of endotracheal intubation for mechanical ventilation in patients under general anesthesia, which changes the normal breathing pattern and further accelerates the evaporation of moisture in the oral cavity, causing patients to feel dry mouth after surgery.

[0003] Patent application number CN202411399647.6 discloses a device for caring for dry mouth in anesthetized patients, belonging to the field of fluid delivery devices for the human body. It includes a water storage module, a water delivery module, and an elastic bladder. The inlet end of the water delivery module is connected to the water storage module, and the outlet end is connected to a temporary storage tube. A water-retaining plate is installed inside the elastic bladder, and several seepage holes are provided on the outer surface of the elastic bladder. The elastic bladder and the temporary storage tube are connected by a connecting tube filled with a water-absorbing cotton swab. Along the axis of the connecting tube, one end of the water-absorbing cotton swab is inserted into the temporary storage tube, and the other end is tightly fitted to the water-retaining plate. This application uses the water-absorbing cotton swab and the water delivery module to ensure that the water content of the water-retaining plate located in the patient's mouth is always in a supersaturated state, thereby controlling water to continuously enter the patient's mouth in the form of droplets. It achieves continuous water delivery while controlling the water volume, which not only simplifies the nursing procedure for dry mouth but also keeps the patient's mouth moist for a long time, improving the quality of dry mouth care for anesthetized patients.

[0004] When using the above-mentioned method, at least the following problems were found to remain unresolved. First, this method mainly relies on cotton balls inside the drainage holes to achieve a low-flow-rate dripping. However, when the patient's mouth is extremely dry, the flow rate needs to be increased. Since the cotton balls fill the drainage holes, this hinders the rapid flow of water into the patient's mouth. Second, when the patient does not need throat moisturizing temporarily, someone needs to assist in turning off the flow regulator to stop the dripping, which inconveniences communication between the patient and others. When the patient needs throat moisturizing again, the flow regulator needs to be turned back on, making the entire process extremely cumbersome.

[0005] Therefore, in view of the above-mentioned technical defects, it is necessary to propose a device for postoperative dry mouth care for oral patients. Summary of the Invention

[0006] The present invention aims to address the aforementioned technical deficiencies by proposing a dry mouth care device for postoperative oral patients. This device allows patients to independently control the on / off of the water infusion according to their own situation, thereby avoiding the need for assistance from others to turn off the water infusion. Furthermore, when the mouth is extremely dry, patients can also independently adjust the water output, thus solving the problem of inconvenience in operation of existing devices.

[0007] This invention provides a device for postoperative dry mouth care for oral patients, comprising: a water storage bag body, a water delivery pipe, a connector, and a water storage component;

[0008] The water storage bag is filled with water and has a vent pipe from its upper surface to its interior. The upper end of the water supply pipe is connected to the water storage bag body. One end of the connector is connected to the interior of the water storage component, and the other end of the connector is connected to the water supply pipe.

Fixing plates are spaced apart along the top surface of the inner wall of the connector on the right side of the opening, and a connecting plate is slidably arranged between the fixing plates and the opening. The area of ​​the connecting plate is larger than the area of ​​the opening. A water outlet is formed below the opening, connecting the inner wall of the cavity and the outer side of the connector, and the water outlet is opposite to the connecting plate. A vertical groove is formed along the inner wall of the cavity on the right side of the fixing plate, and the groove is connected to the upper surface of the connector. A baffle is slidably arranged from the middle of the groove to the top of the connector. A water inlet pipe is provided in the cavity, and one end of the water inlet pipe passes through and is fixedly set at the center end of the connecting plate. A water-guiding cotton rod is provided on the inner wall of the water inlet pipe.

[0010] The water storage component is equipped with a water storage plate, and the water storage component has seepage holes from the inside to the outside. The other end of the water inlet pipe is connected to the inside of the water storage plate. The upper and lower surfaces of the water storage component are respectively movably equipped with an upper abutment plate and a lower abutment plate. The upper and lower surfaces of the water storage plate are movably equipped with a pressure plate assembly, and the pressure plate assembly includes multiple seepage cotton balls. The seepage cotton balls are opposite to the seepage holes. The connecting piece and the baffle are connected to the pressure plate assembly. The upper abutment plate and the lower abutment plate are connected to the pressure plate assembly.

[0011] Preferably, the water storage component is a disc-shaped shell, and a support ring is suspended in the middle of the interior of the water storage component. A support block is provided between the outer side of the support ring and the inner wall of the water storage component. The water storage plate is disposed inside the support ring, and a notch is provided on the inner wall of the support ring and the right side. The notch is interconnected with the upper and lower surfaces of the support ring. One end of the water inlet pipe passes through the notch and extends into the interior of the water storage plate.

[0012] Preferably, the pressure plate assembly includes an upper pressure plate and a lower pressure plate, and the diameters of the upper and lower pressure plates are adapted to each other with the inner diameter of the support ring. The upper and lower pressure plates are respectively movably disposed at the upper and lower ends of the water storage plate, and multiple openings are arrayed on the upper and lower surfaces of the upper and lower pressure plates. A sponge layer is disposed in the openings. Water-retaining gauze is disposed on the upper surface of the upper pressure plate and the lower surface of the lower pressure plate. The water-permeable cotton ball is connected to the water-retaining gauze. The upper and lower ends of the inner wall of the water storage component are provided with grooves, and the grooves are corresponding to the upper and lower pressure plates. The water-permeable hole is opened between the inner wall surface of the groove and the outer surface of the water storage component.

[0013] Both the upper and lower abutments are fixedly equipped with connecting rods at the ends facing the water storage component, and one end of the connecting rod is connected to the corresponding upper or lower pressure plate. The upper surface of the water storage component is provided with a spring piece, wherein the upper end of the spring piece abuts against the lower surface of the upper abutment, and the lower end is fixedly connected to the upper surface of the water storage component.

[0014] Preferably, a first support rod and a second support rod are respectively provided on the right side of the upper pressure plate and the lower pressure plate in the horizontal direction. The first support rod and the second support rod are both arranged opposite to the notch. One end of the first support rod is connected to the upper surface of the baffle plate, and one end of the second support rod extends horizontally to the bottom of the connector. A top rod is vertically provided on the upper surface of the second support rod. The upper end of the top rod passes through the inside of the receiving cavity and is connected to the lower surface of the connector plate.

[0015] Preferably, a frame-shaped sealing ring is provided at the upper end of the inner wall of the vertical groove along the circumferential direction, and a first groove and a second groove are respectively provided at the upper and lower ends of the outer wall of the baffle along the circumferential direction, and the first groove and the second groove are respectively arranged opposite to the sealing ring. When the baffle is in the initial state, the sealing ring can be fitted into the second groove, and when the baffle moves downward, the sealing ring can be fitted into the first groove.

[0016] Preferably, when the upper and lower abutments are not compressed, the connecting plate can be opposite to the water outlet, and the water inlet pipe can be offset from the fixing plate;

[0020] Preferably, the lower end of the water supply pipe has a circular connecting groove along its inner wall surface, and the end of the connector facing the water supply pipe has an annular connecting part. In use, the connector can be threadedly connected to the connecting groove of the water supply pipe through the connecting part.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention, through the cooperation of the upper and lower support plates, the water outlet, and the connector, allows patients to independently control the water output of the water storage plate. In actual use, patients can squeeze or release the upper and lower support plates by using oral movements, which will drive the water inlet pipe and connecting plate inside the connector to move. After the movement, the patient can flexibly switch between the normal water delivery mode and the high water volume mode. This design can meet the need for rapid water replenishment when the mouth is extremely dry, and can also restore normal water output when a large amount of water replenishment is not needed, thus accurately adapting to the patient's real-time dry mouth condition.

[0023] 2. The present invention, through the design of the connector, vertical groove and baffle, allows the user to independently cut off the water delivery channel of the water storage plate. In practice, when the patient does not need water delivery, the upper abutment can be squeezed to drive the baffle to slide downward in the vertical groove. After sliding, the receiving cavity in the connector can be closed, thus cutting off the water delivery. Moreover, no assistance from others is required during the cutting process, thereby effectively improving the convenience and autonomy of the equipment. Attached Figure Description

[0043] As attached Figure 1 To the attached Figure 6 A device for postoperative dry mouth care for oral patients includes a water storage bag body 1, a water supply pipe 2, a connector 21, and a water storage component 3. The water storage bag body 1 is filled with water, and a vent pipe 11 is formed from its top end to its top face. A connecting cap is threaded to the upper end of the vent pipe 11. Connecting straps 12 for binding are provided on both sides of the top of the water storage bag body 1. In use, the water storage bag body 1 can communicate with the outside air through the vent pipe 11 to ensure smooth water supply.

[0044] The upper end of the water supply pipe 2 is connected to the lower end of the interior of the water storage bag body 1. The lower end of the water supply pipe 2 has a circular docking groove 271 along its inner wall. One end of the connector 21 is connected to the interior of the water storage component 3, while the other end has a circular docking part 27. In use, the connector 21 and the water supply pipe 2 can be connected by the docking part 27 and the docking groove 271. A water inlet pipe 26 is provided inside the connector 21. One end of the water inlet pipe 26 extends into the interior of the water storage component 3. A water-guiding cotton swab 261 is provided on the inner wall of the water inlet pipe 26. In use, the water inlet pipe 26 can guide the water flow through the water-guiding cotton swab 261.

[0045] In the above structure, when the water storage bag body 1 is suspended on the infusion stand next to the hospital bed by the connecting strap 12, a height difference can be formed with the hospital bed. Then, combined with the ventilation tube 11, it can communicate with the outside atmosphere, so that the water in the water storage bag body 1 can continuously flow to the water delivery tube 2. When the water flows through the water delivery tube 2 and enters the connector 21, it can be introduced into the water storage component 3 through the water-guiding cotton swab 261 in the water-guiding tube 26. Finally, when the patient puts the water storage component 3 into his mouth, the water can enter the oral cavity through the water storage component 3 to moisten the throat.

[0046] The water storage component 3 is a disc-shaped shell, with a support ring 31 suspended in the middle of its interior. A support block for maintaining balance is positioned between the outer surface of the support ring 31 and the inner wall of the water storage component 3. A water storage plate 33 is housed inside the support ring 31. The main body of the water storage plate 33 is made of absorbent sponge. A notch 32 is formed between the right side of the inner wall of the support ring 31 and its right end face. This notch 32 is interconnected with the upper and lower surfaces of the support ring 31. One end of a water inlet pipe 26 passes through the notch 32 and extends into the water storage plate 33. This design allows water to be introduced into the water storage component 3 through a water-guiding cotton swab 261 inside the water inlet pipe 26, thus maintaining its saturation.

[0047] Meanwhile, a disc-shaped upper abutment plate 4 and a lower abutment plate 41 are movably disposed on the upper and lower surfaces of the water storage component 3, respectively. Multiple connecting rods 43 are fixedly disposed at the ends of the upper abutment plate 4 and the lower abutment plate 41 facing the water storage component 3, and one end of each connecting rod 43 extends through into the interior of the water storage component 3. An upper pressure plate 34 and a lower pressure plate 341 are movably disposed above and below the water storage plate 33, respectively. The diameters of the upper pressure plate 34 and the lower pressure plate 341 are adapted to the inner diameter of the support ring 31, and both the upper pressure plate 34 and the lower pressure plate 341 are connected to the connecting rods 43. This design allows the upper abutment plate 4 and the lower abutment plate 41 to be squeezed by closing the mouth or by using the back of the tongue after the water storage component 3 is placed in the patient's mouth. For example, when using it, the user can apply an upward thrust to the water storage device 3 with the back of their tongue. Under the action of the thrust, the back of the tongue and the upper wall of the mouth can squeeze the water storage plate 33 together. After squeezing, the excess water in the water storage plate 33 can be squeezed out, thus stopping the water from flowing out.

[0048] Multiple openings 35 are arrayed on the upper and lower surfaces of the upper pressure plate 34 and the lower pressure plate 341, and a sponge layer 36 for water delivery is provided in the openings 35. Then, several layers of water-retaining gauze 37 are provided on the upper surface of the upper pressure plate 34 and the lower surface of the lower pressure plate 341. The water-retaining gauze 37 is made of medical gauze, and multiple water-permeable cotton balls 38 are arrayed on the end of the water-retaining gauze 37 facing away from the water-retaining plate 33. This design allows the upper pressure plate 34 and the lower pressure plate 341 to be reset when water needs to be dispensed from the water-retaining plate 33. After the reset, the water in the water-retaining plate 33 will gradually become saturated, so the water can flow through the openings 35 and the sponge layer 36 to the water-retaining gauze 37 layer. Finally, the water drips continuously from the water-permeable cotton balls 38, thus achieving the throat-moistening function.

[0049] Furthermore, slots 39 are provided at the upper and lower ends of the inner wall of the water storage component 3, and the slots 39 are corresponding to the upper pressure plate 34 and the lower pressure plate 341. At the same time, seepage holes 391 are arrayed from the inner wall surface of the slots 39 to the outer surface of the water storage component 3, and the seepage holes 391 are opposite to the seepage cotton balls 38. This design allows the two pressure plates to enter the slots 39 in the corresponding positions when the upper pressure plate 34 and the lower pressure plate 341 are reset. Then the seepage cotton balls 38 at the two pressure plates can also be properly embedded in the seepage holes 391, thus ensuring that the water can drip normally from the seepage holes 391 into the mouth.

[0050] Furthermore, multiple spring pieces 42 are provided on the upper surface of the water storage component 3. The upper end of the spring piece 42 abuts against the lower surface of the upper abutment plate 4, while the lower end is fixedly connected to the upper surface of the water storage component 3. This design allows the spring piece 42 to apply an upward elastic force to the upper abutment plate 4. The water outlet state of the water storage component 3 can be precisely controlled by the change in elastic force. For example, when it is necessary to close the water outlet channel of the water storage component 3, both the upper abutment plate 4 and the lower abutment plate 41 need to be squeezed simultaneously; when it is necessary to keep the water storage component 3 discharging water normally, it is not necessary to squeeze the upper abutment plate 4 and the lower abutment plate; when it is necessary to increase the water outlet of the water storage component 3, the lower abutment plate 41 needs to be pushed upward separately.

[0051] Furthermore, to increase bite comfort, the upper and lower abutments 4 and 41 are made of silicone material with a certain degree of hardness and elasticity, avoiding discomfort caused by being too hard or too soft. For example, medical-grade liquid silicone (LSR) material can be used, with a hardness typically between 30-60 Shore A, possessing both appropriate rigidity and flexibility to meet the support requirements during bite without easily deforming, while also exhibiting good elasticity and quick rebound after compression. In addition, to facilitate water flow, the upper and lower abutments 4 and 41 can adopt a hollow structure. This design ensures that water is not obstructed when dripping, allowing the water to quickly come into contact with the oral cavity.

[0052] like Figure 2 , Figures 4 to 6 The connector 21 is a cylindrical tube with a cavity 22 formed on its right side. A rectangular opening 23 is vertically formed on the left side of the inner wall of the cavity 22, extending to its left end. A fixing piece 251 is fixed and spaced along the top surface of the inner wall of the connector 21 on the right side of the opening 23. The lower end of the fixing piece 251 corresponds to the middle of the opening 23. A connecting piece 25 is then attached to and slidably positioned at the adjacent end of the fixing piece 251 and the opening 23. The area of ​​the connecting piece 25 is larger than the area of ​​the opening 23, and one end of the water pipe 26 passes through and is fixedly positioned at the center end of the connecting piece 25. This design allows the connecting piece 25 to move the water pipe 26 up and down.

[0053] A water outlet 24 is provided below the opening 23, extending from the bottom of the inner wall of the receiving cavity 22 to the outer end face of the connector 21. The lower end of the connecting piece 25 is positioned opposite to the water outlet 24. This design allows the water outlet 24 to be blocked when the connecting piece 25 is not in motion. After being blocked, the water can only enter the water storage device 3 through the water-guiding cotton swab 261 in the water-guiding pipe 26. When it is necessary to increase the water output, the connecting piece 25 can be moved, allowing the connecting piece 25 to be moved away from the water outlet 24. After being moved away, the water outlet 24 can be opened to allow the water to quickly enter the water storage device 3. Finally, the water flows to the oral cavity through the seepage hole 391.

[0054] A U-shaped vertical groove 28 is vertically formed on the right side of the fixing plate 251 along the inner wall of the receiving cavity 22. The vertical groove 28 is also connected to the upper surface of the connector 21. Then, a U-shaped baffle 29 is fitted and slidably arranged in the middle of the vertical groove 28 to the top of the connector 21. In use, the downward moving baffle can contact the bottom surface of the inner wall of the receiving cavity 22. After contact, the internal space of the receiving cavity 22 can be sealed, and after sealing, water can be prevented from entering the water storage component 3.

[0055] Furthermore, a frame-shaped sealing ring 281 is provided along the circumference of the upper end of the inner wall of the vertical groove 28. Then, a first groove 291 and a second groove 292 are respectively formed along the circumference of the upper and lower ends of the outer wall of the baffle 29. Both the first groove 291 and the second groove 292 are positioned opposite to the sealing ring 281. In the initial state, the sealing ring 281 can fit into the second groove 292. When the baffle 29 moves downwards, the sealing ring 281 can fit into the first groove 291. This design allows for sealing of the connection between the baffle 29 and the vertical groove 28 through the sealing ring 281 and the grooves, ensuring that water can be stably retained within the connector 21.

[0056] Furthermore, a first support rod 5 and a second support rod 51 are respectively arranged horizontally on the right side of the upper pressure plate 34 and the lower pressure plate 341. Both the first and second support rods 5 and 51 are positioned opposite to the notch 32. One end of the first support rod 5 is connected to the upper surface of the baffle 29, and one end of the second support rod 51 extends horizontally to below the connector 21. A top rod 52 is also vertically arranged on the upper surface of the second support rod 51. The upper end of the top rod 52 passes through the cavity 22 and connects to the lower surface of the connecting piece 25. This design allows the connecting piece 25 and the baffle 29 to move via the first and second support rods 5 and 51 when the user presses the upper and lower pressure plates 41, thus blocking the water supply channel.

[0057] Furthermore, when the upper abutment plate 4 and the lower abutment plate 41 are not compressed, the connecting plate and the outlet 24 are positioned opposite each other, while the water inlet pipe 26 and the fixing plate 251 are offset. When the lower abutment plate 41 is compressed alone, the connecting plate and the outlet 24 are offset, while the water inlet pipe 26 and the fixing plate 251 are positioned opposite each other. When the upper abutment plate 4 and the lower abutment plate 41 are compressed together, the water inlet pipe 26 and the fixing plate 251 are offset, while the baffle plate 29 is positioned opposite the outlet 24. This design allows the closing state of the water inlet pipe 26 and the outlet 24 to be controlled after the upper abutment plate 4 and the lower abutment plate 41 are activated.

[0058] like Figure 1 A flow rate regulator 6 and a drip pot 7 are sequentially installed on the water infusion pipe 2. The structure of the flow rate regulator 6 and the drip pot 7 is exactly the same as that of the flow rate regulator 6 and the drip pot 7 used for intravenous injection in the prior art. This design allows the user to intuitively display the dripping frequency of the water droplets through the drip pot 7, while the flow rate regulator 6 can further adjust the flow rate of the water in the infusion pipe.

[0059] In addition, it should be noted that in order to prevent external dust from entering the water bag, a corresponding dust filter, such as medical-grade sterile gauze, can be installed at the vent pipe 11. In this way, the porous structure of the dust filter can block dust and ensure the circulation with the outside air during use.

[0060] The following is the specific usage process of this invention:

[0061] First, the water storage bag body 1 is suspended on the IV stand next to the hospital bed by the connecting strap 12. After suspension, a certain height difference is formed between the water storage bag body 1 and the hospital bed, which can provide power for the subsequent water flow. Then, the connecting cap is unscrewed to allow the water storage bag body 1 to communicate with the outside atmosphere through the vent tube 11, balance the air pressure inside the water storage bag, and ensure that the water can flow out smoothly.

[0062] When a patient needs to use the device to relieve dry mouth, they first place the water reservoir 3 into their mouth. At this time, the water in the water storage bag body 1 flows to the connector 21 through the water supply pipe 2 under the action of gravity. After entering the connector 21, the water is introduced into the water storage plate 33 in the water reservoir 3 through the water-guiding cotton swab 261 in the water-guiding pipe 26. As water is continuously introduced, the water storage plate 33 gradually reaches saturation. The saturated water permeates through the openings 35 on the upper pressure plate 34 and the lower pressure plate 341, through the sponge layer 36, into the water-retaining gauze 37, and finally seeps out from the water-permeable cotton ball 38 and drips into the patient's mouth through the seepage hole 391 on the water reservoir 3 to relieve the symptoms of dry mouth.

[0063] If the patient feels their mouth is moist and does not need intravenous fluids temporarily, they can close their mouth or use the back of their tongue to squeeze the upper and lower abutments 4 and 41. Under this squeezing action, the upper and lower abutments 4 and 41, via the connecting rod 43, move the upper pressure plate 34 and the lower pressure plate 341 simultaneously toward the water reservoir 33. This allows them to work together to squeeze the water reservoir 33, squeezing out excess water and preventing further water flow. At the same time, the first support rod 5 on the right side of the upper pressure plate 34 will move the baffle 29 downward within the vertical groove 28. After the baffle 29 moves downward, it can seal the inner wall of the receiving cavity 22, preventing water from entering the connector 21 and thus cutting off the intravenous fluid supply.

[0064] When a patient's mouth is extremely dry and they need to increase the amount of water they need, they can use their tongue to push the lower abutment 41 upwards. After moving upwards, the push rod 52 can drive the connecting piece 25 to slide upwards between the fixed piece 251 and the opening 23. This allows the connecting piece 25 to be removed from the water outlet 24. After it is removed, the water can flow directly from the water outlet 24 into the water storage unit 3, which speeds up the flow of water into the mouth and thus meets the patient's need for a large amount of water.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
