Description

TECHNICAL FIELD

[0001] The utility model relates to medical nursing equipment technical field especially, relate to a multifunctional device that relieves patient postoperative dry mouth. BACKGROUND

[0002] Postoperative patients often face dry mouth, thirst, dry throat and other discomfort symptoms during the anesthesia recovery period. These symptoms not only significantly affect the comfort of patients, but also may have adverse effects on postoperative recovery. Due to the effects of anesthetic drugs and the requirement of fasting and water restriction during surgery, the oral mucosa of patients is prone to dryness, leading to difficulty in swallowing, sore throat, and increasing the risk of infection. In addition, if the dry mouth problem is not treated in time, it may cause bacterial proliferation in the oral cavity, thereby affecting the overall health status.

[0003] Currently, clinical treatment mainly relies on manual methods to moisten the oral cavity of patients, such as using a cotton swab to wipe or wet gauze to infiltrate the lips. However, these traditional methods have many limitations:

[0004] Low efficiency: medical staff need to operate frequently, which not only consumes a lot of time, but also is difficult to ensure the consistency and durability of the moistening effect each time.

[0005] Inconvenient operation: for patients in the anesthesia recovery period, they may not be able to cooperate with nursing actions autonomously, increasing the difficulty of nursing; at the same time, manual operation also increases the risk of cross-infection.

[0006] Lack of targeting: the above-mentioned methods can only provide superficial relief, and cannot effectively solve the problem of dryness of the oral mucosa caused by anesthesia, especially for the dryness of the throat, which has little help.

[0007] Insufficient lip care: postoperative patients often have dry and cracked lips, and the existing nursing methods are mostly to apply liquid nursing liquid, but this method often has poor lip moisturizing effect and short retention time due to low viscosity and easy evaporation. More importantly, these nursing measures are usually performed separately, and there is no unified device to deal with multiple symptoms at the same time.

[0008] CN218529059U discloses a mouth patch designed specifically for postoperative patients to relieve dry mouth, which effectively prevents dry mouth and promotes saliva secretion to relieve the thirst of patients by using a specific ointment (such as Yuquan Powder) built-in. However, this patent focuses on relieving dry mouth, a single symptom, and does not provide specific solutions or corresponding nursing measures for other related symptoms commonly seen after surgery, such as dry throat and cracked lips. Therefore, in terms of comprehensively covering the comprehensive nursing needs of postoperative patients, this mouth patch still has room for improvement, especially in terms of integrating multifunctional nursing mechanisms and improving overall nursing effect.

[0009] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when making the utility model, but limited by the size and not all details and contents are listed in detail, but this does not mean that the utility model does not have the characteristics of these prior arts, on the contrary, the utility model has all the characteristics of the prior art, and the applicant reserves the right to add related prior art in the background art. Content of the utility model

[0010] In view of the defects of the prior art, the application provides a multifunctional device for relieving postoperative dry mouth of patients, aiming at solving one or more technical problems in the prior art.

[0011] The utility model provides a multifunctional device for relieving postoperative dry mouth of patients, which comprises a support main body covering the mouth, and the support main body forms a cavity for accommodating a water supply part and a lip moisturizing part between its outer wall surface and inner wall surface, wherein the liquid storage bin of the water supply part is connected with a plurality of spray outlets and a plurality of water dripping outlets in the inner wall surface and opening towards the inside of the oral cavity in the cavity; the paste storage bin of the lip moisturizing part is connected with a plurality of paste outlets in the inner wall surface and opening towards the surface of the lips in the cavity.

[0012] The utility model realizes multi-point output by setting the spray outlet, water dripping outlet and paste outlet, and the three outlets can respectively provide precise nursing for different needs of the inside of the oral cavity and the surface of the lips, ensuring that the liquid and the lip balm can be accurately applied to the required position, and improving the nursing efficiency. Specifically, the spray outlet and the water dripping outlet are respectively applicable to the needs of moistening the throat of the oral cavity and relieving thirst, and provide flexible water supply mode selection. The paste outlet focuses on lip care, ensures that the lip balm is evenly distributed on the lips, and avoids the uneven problem that may be caused by the traditional smearing method. In addition, by setting the water supply part and the lip moisturizing part in the cavity inside the support main body, the space is effectively utilized. This compact integrated design reduces the overall volume of the device, and also simplifies the operation steps in the use process.

[0013] According to a preferred embodiment, the support body extends a ring-shaped dental tray ring from its inner wall surface in a direction towards the inside of the oral cavity, and the side of the dental tray ring away from the inner wall surface forms a plane for configuring the spray outlet and the droplet outlet, wherein the droplet outlet is distributed in the area of the dental tray ring plane close to the corners of the two sides of the mouth, and the spray outlet is distributed between the two droplet outlets. The ring-shaped dental tray ring provides a stable support point for the patient's teeth, ensuring that the device does not easily shift during the entire use process. This design not only improves the comfort of wearing, but also enhances the fixation effect of the device in the oral cavity, reducing the risk of device sliding caused by patient movement or unconscious action. In addition, configuring the droplet outlet near the corners of the two sides of the mouth can help activate the salivary glands in the corner area, further increasing the moisture inside the oral cavity, thereby better relieving thirst; and distributing the spray outlet in the central area between the two corners of the mouth can more widely cover the inside of the oral cavity, suitable for situations that require rapid moistening of the entire oral cavity and throat.

[0014] According to a preferred embodiment, a spray switch is configured on the pipeline between the liquid storage bin and the spray outlet, and a droplet switch is configured on the pipeline between the liquid storage bin and the droplet outlet, wherein the spray switch and the droplet switch are located on the outer wall surface of the support body. By setting the spray switch and the droplet switch on the outer wall surface of the support body, medical personnel or family members can easily access and operate these switches without removing the device or deep into the oral cavity. This design greatly simplifies the nursing process and improves the convenience and efficiency of operation. By clearly distinguishing the spray switch and the droplet switch and arranging them on the outer wall surface, it avoids misoperation caused by confusion of different functions. Especially during the postoperative anesthesia recovery period, the patient's consciousness may not have fully recovered, and this design ensures safe use even in the case of unconsciousness of the patient.

[0015] According to a preferred embodiment, a lip moisturizing ring is configured on the radially outer side of the dental tray ring and attached to the inner wall surface, and a plurality of paste outlets are distributed on the surface of the lip moisturizing ring in contact with the lips, and the paste outlets are connected to the paste storage bin through the delivery pipe. The lip moisturizing ring closely adheres to the surface of the lips, ensuring that the paste outlets can apply lip balm directly to the area that needs to be moisturized. This design avoids the uneven or excessive problems that may occur in traditional application methods, achieving more precise and effective lip moisturizing effect. In addition, the multiple paste outlets are evenly distributed on the lip moisturizing ring, ensuring that the lip balm can be evenly distributed on the entire lip surface, especially some hard-to-reach corners can also be fully cared for, improving the overall lip moisturizing effect.

[0016] According to a preferred embodiment, the lip moisturizing part comprises a motor arranged in the internal cavity of the support body, and the motor is electrically connected with the lip moisturizing switch arranged on the outer wall surface. The telescopic rod of the motor can extend into the internal cavity of the storage chamber, and an extrusion plate is formed at the end away from the motor. The motor can drive the telescopic rod to move towards the side close to the delivery tube, so that the extrusion plate pushes the lip moisturizing cream in the storage chamber into the lip moisturizing ring. Since the motor drives the telescopic rod to move the same distance and at the same speed each time, the amount of lip moisturizing cream pushed each time is accurate and consistent. This avoids the problem of over or under application that may occur when manually applying, and provides more stable and reliable care effect.

[0017] According to a preferred embodiment, the support body comprises a breathing port, which penetrates the outer wall surface and the inner wall surface and is located in the internal region surrounded by the dental tray ring. The design of the breathing port ensures that the patient can breathe normally when wearing the device and does not feel suffocated or have difficulty breathing due to the care equipment in the oral cavity. In addition, the presence of the breathing port reduces the occupation of the internal space of the support body, avoiding unnecessary pressure on the tongue, soft palate and other parts, and improving the comfort during wearing.

[0018] According to a preferred embodiment, the outer wall surface of the support body is arranged with a liquid injection port in an openable and closable manner on the surface of the liquid storage chamber, and an addition port is arranged on the surface of the storage chamber. The openable and closable design of the liquid injection port and the addition port allows medical staff or family members to conveniently supplement liquid or lip moisturizing cream into the liquid storage chamber and the storage chamber without the need to disassemble the entire device or deep into the internal oral cavity. This design simplifies the replenishment process and improves the convenience and efficiency of operation.

[0019] According to a preferred embodiment, the spray outlet is configured as a spray head with a plurality of holes, so that the liquid stored in the liquid storage chamber can be sprayed in the form of water mist. The drop outlet is configured as a single-hole drop head, so that the liquid stored in the liquid storage chamber can be dropped in the form of water drops. By designing two different forms of liquid output, this scheme can meet the different oral cavity moistening needs of postoperative patients. The multi-hole design of the spray outlet allows the liquid to be uniformly distributed in the form of fine water mist particles, which is suitable for situations that require a large amount of moisture or rapid relief of dry mouth. The single-hole design of the drop outlet ensures that only one drop of liquid is released each time, which is suitable for situations that require a small amount of continuous moisture supply.

[0020] According to a preferred embodiment, the periphery of the breathing port is arranged with a hand holding part, which extends outward from the outer wall surface of the support body in a manner that avoids blocking the breathing port. The hand holding part is designed to ensure that the breathing port is completely open and will not be blocked by hands or other objects. This design ensures that the air flow path is not blocked, reducing the risk of breathing difficulties caused by improper wearing or operation of the device, and ensuring the safety of the patient's breathing.

[0021] According to a preferred embodiment, the outer wall surface is provided with a mist indicator lamp and a dripping indicator lamp, wherein the mist indicator lamp is electrically connected with the mist switch, and the dripping indicator lamp is electrically connected with the dripping switch. The mist indicator lamp and the dripping indicator lamp provide intuitive visual signals to help the user confirm the current operation state. When the corresponding switch is activated, the indicator lamp is lit, clearly informing the user which function is running, thereby reducing the possibility of misoperation.

DETAILED DESCRIPTION

[0031] The present application will be described in detail below with reference to the accompanying drawings.

[0032] The present application relates to a multifunctional device for relieving postoperative dry mouth of a patient, such asFigure 1 As shown, it includes a support body 100 that covers the mouth. This support body 100 can be designed as an arc-shaped cover to ensure a close fit to the facial contours without compressing the patient. A sealed cavity is formed between the outer wall surface 101 and the inner wall surface 102 of the support body 100 to accommodate a water supply section 110 and a lip moisturizer section 120. The water supply section 110 can moisturize the patient's mouth and throat with a fine mist and can also provide a small amount of water to relieve thirst and dry throat; the lip moisturizer section 120 can apply lip care products to the patient's lips to prevent chapping.

[0033] Preferably, such as Figures 1-3 As shown, the water supply unit 110 includes two reservoirs 111 for storing drinking water, located inside the cavities at both ends of the support body 100. Each reservoir 111 is designed with an independent, transparent shell, but can be connected to each other through one or more channels to ensure that liquid can flow between the two reservoirs 111, thereby maintaining a balanced drinking water supply to the device. These reservoirs 111 are further connected through one or more independent channels to multiple micro-spray outlets 114 and drip outlets 117 located on the inner wall surface 102, opening towards the inside of the oral cavity. The spray outlets 114 and drip outlets 117 are preferably designed to be evenly distributed on the inner wall surface 102 near the oral cavity to ensure that the liquid can gently and effectively cover the entire oral mucosa, avoiding direct impact on wounds or sensitive areas. This arrangement not only improves the effectiveness of liquid distribution but also enhances patient comfort.

[0034] Preferably, each spray outlet 114 is configured as a nozzle with several micro-holes to ensure that the liquid stored in the reservoir 111 can be sprayed out from the spray outlet 114 in the form of a fine and uniform water mist. The diameter and spacing of each hole in these nozzles are consistent, thus achieving a stable spray effect. The spray outlet 114 can be made of nozzles such as those from the BETE MicroFine series, with a nozzle diameter of approximately 0.25–1.0 mm and an internal spiral guide structure that causes the liquid to rotate before being sprayed, further improving the dispersion and coverage of the water mist, making it suitable for applications requiring fine spraying.

[0035] Preferably, each drip outlet 117 is configured as a single-hole dripper to ensure that the liquid stored in the reservoir 111 can drip out drop by drop. The drip outlet 117 can be, for example, a Lee Company LEEJET series micro-pump nozzle with a nozzle diameter of approximately 0.1–1.5 mm. This drip outlet 117 can provide a small amount of drinking water to relieve the patient's thirst and dry throat.

[0036] Preferably, in order to ensure the safety of the drinking water transmission, all components in contact with the liquid are made of high biocompatibility medical grade materials and are subjected to strict sterile processing, further ensuring the safety and hygiene standards of the device.

These openings are designed with a flip cover, and the flip cover is connected to the support body 100 by a hinge to ensure smooth opening and good sealing. The inside of the flip cover is provided with a silica gel sealing ring to prevent liquid or lip balm from leaking while maintaining a sterile environment. The liquid filling port 112 is equipped with a transparent cap with a scale, which allows medical staff to visually check the liquid level and ensure accurate filling. The additive port 122 is designed with a wide caliber to facilitate the use of standard size syringes or other containers to add lip balm, reducing the difficulty of operation.

[0039] Preferably, as shown in Figure 1 , Figure 4As shown, the support body 100 extends an annular dental tray 140 from its inner wall 102 toward the inside of the oral cavity. The dental tray 140 is designed with an ergonomic arc shape to ensure that the patient's teeth can naturally bite down on it, reducing discomfort. The dental tray 140 is made of soft, medical-grade silicone material, providing good support without compressing or damaging oral tissues. A flat surface is formed on the side of the dental tray 140 away from the inner wall 102 for accommodating the aforementioned spray outlet 114 and drip outlet 117, allowing liquid to flow smoothly from both outlets without stagnation.

[0040] Preferably, such as Figure 4 As shown, the drip outlets 117 are distributed on the surface of the denture ring 140 near the corners of the mouth to provide localized hydration, especially suitable for patients whose corners of the mouth are prone to dryness. The spray outlets 114 are evenly distributed between the drip outlets 117 on both sides, ensuring that the fine mist gently covers the entire oral mucosa, avoiding direct impact on wounds or sensitive areas. This layout not only improves the effectiveness and accuracy of liquid distribution but also enhances patient comfort.

[0041] Preferably, such as Figures 1-3 As shown, a spray switch 113 is installed on the drinking water channel between the reservoir 111 and the spray outlet 114, and a drip switch 116 is installed on the drinking water channel between the reservoir 111 and the drip outlet 117. Both switches are located on the outer wall 101 of the support body 100 and consist of a valve core and a spring. They are used to open and close the corresponding channels, facilitating operation by medical staff to provide oral care to patients as needed, while reducing unnecessary direct contact with the patient's mouth and lowering the risk of cross-infection. The outer wall 101 of the support body 100 is also equipped with a spray indicator light 115 and a drip indicator light 118 to display the real-time operating status of the spray and drip functions. The spray indicator light 115 is electrically connected to the spray switch 113 via a wire, while the drip indicator light 118 is connected to the drip switch 116 via a separate circuit. This design ensures that each indicator light illuminates only when its corresponding switch is activated, providing clear and intuitive operational feedback to medical staff and facilitating rapid and accurate confirmation of the device's operating status in the postoperative care environment.

[0042] Preferably, such as Figures 4-7As shown, the radially outer side of the dental tray ring 140 is configured with a lip moisturizing ring 128 attached to the inner wall surface 102, which is designed as an elliptical structure in line with the natural contour of the lips to ensure close contact with the surface of the lips. A number of lip balm outlets 129 are evenly distributed on the surface of the lip moisturizing ring 128 in contact with the lips, which are connected to the lip balm storage compartment 121 through the delivery pipe 127 arranged in the internal cavity of the support body 100, so that the lip balm can be directly applied to the patient's lips through the lip balm outlets 129 to prevent dryness. The lip moisturizing ring 128 is preferably made of flexible material to ensure that the patient does not feel uncomfortable during use. In addition, the delivery pipe 127 of the lip balm is preferably configured as two, the ends of the two delivery pipes 127 can be connected to the short axis end of the elliptical lip moisturizing ring 128, ensuring that the path is basically consistent, so that the lip balm supplied to each lip balm outlet 129 is more uniform. The delivery pipe 127 is made of medical-grade silicone material, which has good flexibility and anti-aging performance, and can ensure that it does not deform during long-term use. The lip moisturizing ring 128 can be designed to be detachable and connected to the delivery pipe 127, thereby facilitating cleaning and disinfection to ensure the safety and hygiene of the equipment.

[0043] Preferably, as shown in Figure 4 , Figure 6 , the size of the lip balm outlets 129 on the surface of the lip moisturizing ring 128 gradually increases from both short axis ends to both long axis ends, and this gradual design ensures that after the lip balm enters the inner cavity of the lip moisturizing ring 128 from both short axis ends through the delivery pipe 127, it can effectively spread to both long axis ends of the lip moisturizing ring 128 through gravity and extrusion. During the diffusion process, due to the smaller middle lip balm outlets 129 and the larger lip balm outlets 129 on both sides, this design not only promotes the uniform distribution of the lip balm, but also ensures that the outflow speed and amount of the lip product remain consistent throughout the lip moisturizing ring 128.

[0044] Preferably, in combination with Figure 1 and Figure 5 , the lip moisturizing part 120 includes a micro DC motor 124 arranged in the internal cavity of the support body 100, which is electrically connected to the lip moisturizing switch 123 located on the outer wall surface 101 through a flexible cable. The telescopic rod 125 of the motor 124 is made of corrosion-resistant material and can smoothly extend into the inside of the lip balm storage compartment 121 and form a flexible and sealed extrusion plate 126 at the end away from the motor 124. When the operator presses the lip moisturizing switch 123, the motor 124 drives the telescopic rod 125 to move towards the side close to the delivery pipe 127, and the extrusion plate 126 will uniformly push the lip balm in the lip balm storage compartment 121, ensuring that it smoothly enters the lip moisturizing ring 128, thereby realizing automatic lip care.

[0045] Preferably, as shown in Figure 1As shown, the support body 100 comprises a breathing port 130 which penetrates the outer wall surface 101 and the inner wall surface 102 and is located in the internal area surrounded by the dental tray ring 140. The breathing port 130 adopts a circular or oval design, and the edge is rounded to reduce potential irritation to the oral tissue. To ensure the safety of breathing, a filter screen can be arranged inside the breathing port 130 to intercept particulate matter in the air, ensure the sterile state of the treatment environment, and ensure smooth and safe breathing of the patient. The periphery of the breathing port 130 is provided with a hand-held portion 150 which extends outwardly from the outer wall surface 101 of the support body 100 to ensure comfortable and stable holding by medical staff. The hand-held portion 150 is made of anti-slip material to increase the friction force during operation and prevent accidental slipping. In particular, the design of the hand-held portion 150 deliberately avoids the position of the breathing port 130 to ensure that it will not be blocked in any way, so as not to affect the air circulation.
