Description

Technical Field

[0001] This invention belongs to the field of postoperative care device technology, specifically relating to an auxiliary device for improving dry mouth and sore throat after extubation. Background Technology

[0002] General anesthesia surgery requires endotracheal intubation. After extubation, patients commonly experience discomfort such as dry mouth, sore throat, and a foreign body sensation in the throat, with an incidence rate exceeding 70%, severely impacting their postoperative recovery experience. Current nursing care methods mainly include: moistening the lips with cotton swabs dipped in water, patient-administered throat gargling with throat lozenges, and applying ice packs to the neck. A search of existing patents reveals the following shortcomings in disclosed related nursing devices:

[0003] Most existing gargling devices require patients to hold them by hand. Postoperative patients are weak and it is strenuous to hold them for a long time. Moreover, the voluntary gargling action can easily pull on the pharyngeal wound and aggravate the pain. Most throat lozenges are administered at room temperature. Low-temperature lozenges can irritate the pharynx, while high-temperature lozenges can aggravate pharyngeal edema. It is impossible to maintain a constant temperature for continuous administration.

[0004] The cold compress device is a fixed ice pack, which cannot move synchronously with the patient's swallowing and head turning movements. It is easy to shift, resulting in inaccurate cold compress positioning and poor conditioning effect. It does not achieve the linkage between oral gargling and cold compress conditioning. It can only gargle or only apply cold compress, which is a single conditioning method and has limited improvement effect. Therefore, we propose an auxiliary conditioning device to improve dry mouth and sore throat after tube removal. Summary of the Invention

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 This invention provides a technical solution for an auxiliary treatment device to improve dry mouth and sore throat after tube removal: It includes a neck support base 1, which is a U-shaped elastic support with an opening facing forward. A vertical guide rail 2 is fixedly connected to the left outer wall of the neck support base 1. A lifting slider 3 is slidably connected to the vertical guide rail 2. The lifting slider 3 is hinged to an adjustable angle support cantilever 4. An adjustable oral gargling mechanism is connected to the end of the support cantilever 4 away from the lifting slider 3. The adjustable oral gargling mechanism includes a gargling head housing 5, with multiple liquid outlet holes 6 at the bottom of the gargling head housing 5. A flexible liquid-conducting tube 7 is connected, with one end of the flexible liquid-conducting tube 7 connected to a low-speed quantitative drug delivery module. A flexible cooling water bag 8 is embedded in the U-shaped inner side of the neck support base 1, corresponding to the position of the human pharynx. One end of the cooling water bag 8 is fixedly connected to a circulating cooling module. Both the low-speed quantitative drug delivery module and the circulating cooling module are connected to a human-machine interface control module. The neck support base 1 is a U-shaped elastic support with its opening facing forward, fitting snugly around the neck to support the cervical spine and fix the entire device, functioning similarly to a regular medical neck support. Vertical guide rail 2 + lifting slider 3 + supporting cantilever 4 This structure allows for height adjustment by sliding up and down, and also enables rotation to adjust the support angle, precisely positioning the oral gargling mechanism to suit the patient's mouth and adapting to users of different heights and postures. The gargling head housing 5 and dispensing hole 6 are placed inside the mouth, with multiple small holes at the bottom allowing for even dispensing of the conditioning medication, effectively cleaning the mouth, moisturizing the throat, and relieving pain, providing therapeutic gargling for pain relief and cleansing. The flexible liquid guide tube 7 and low-speed quantitative drug delivery module allow the guide tube to deliver the medication from the drug delivery module to the gargling head; the low-speed quantitative dispensing allows for controlled dispensing. The flow rate and dosage of medication are controlled to prevent excessive fluid output from causing choking, ensuring greater safety. The flexible cooling water bag 8 is embedded inside the neck brace, perfectly conforming to the patient's pharynx. It can bend to fit the contour of the neck, constricting blood vessels through cold compresses to reduce pharyngeal swelling and pain after extubation, consistent with the logic of local cold compress analgesia after extubation. The circulating cooling module continuously maintains the water bag at a low temperature, ensuring stable cooling effects. The human-machine interface control module uniformly controls the flow rate of low-speed drug administration and the temperature of the cooling water bag. Users or medical staff can adjust parameters according to the patient's pain level, making operation more convenient.

[0028] Specifically, the low-speed quantitative drug delivery module includes a drug storage chamber 9, with a micro-peristaltic pump 10 connected to the outlet of the drug storage chamber 9. The outlet of the micro-peristaltic pump 10 is connected to a flexible liquid guide tube 7. An electric heating element 11 is embedded in the inner wall of the drug storage chamber 9, and the electric heating element 11 is connected to a human-machine interface control module. The drug storage chamber 9 is a sealed container for storing conditioning / throat-soothing medications. The required medication is pre-filled into this chamber to provide a stable source of medication for continuous drug delivery. The micro-peristaltic pump 10 is the core power control component, connected to the outlet of the drug storage chamber 9 and the flexible liquid guide tube 7. It outputs the medication through peristaltic squeezing. This pump itself... This allows for precise dispensing control at low speed and in small doses, perfectly matching the needs of oral gargling. It prevents the dispensing of too much medication at once, which could cause choking and coughing, fully meeting the requirements of "low-speed, quantitative dispensing." The electric heating pad 11 is embedded in the inner wall of the medication storage chamber 9, which can heat the stored medication and adjust its temperature to a comfortable range close to human body temperature. This avoids cold medication irritating the throat and aggravating pain and discomfort, thus improving the user experience. The electric heating pad 11 is connected to the human-machine interaction control module, meaning that the temperature can be manually adjusted. Medical staff or patients can adjust the temperature to the most suitable level according to their own tolerance, making it more flexible.

[0029] Specifically, the mouthwash head shell 5 is a one-piece molded soft silicone structure. The contour of the mouthwash head shell 5 matches the shape of the human oral vestibule. The diameter of the liquid outlet 6 is 0.8~1.2mm. It is made of medical soft silicone in one piece, which is soft and does not irritate the oral cavity. It is seamless and easy to disinfect. The contour fits the shape of the oral vestibule, so it is stable and does not cause nausea. It is suitable for patients who are unable to fix it after surgery. The liquid outlet 6 will not block the medicine or cause choking due to excessive liquid flow.

[0030] Specifically, the U-shaped opening of the neck support base 1 is connected to two adjustable-length straps 18 at both ends. One strap 18 has a Velcro hook side 19 fixed to its end, and the other strap 18 has a Velcro loop side 20 fixed to its end, forming a detachable wearing and fixing structure. The two can be pressed together to fix it, and can be torn apart to remove it. It is very convenient to wear and remove, and the tightness can be adjusted according to different people's neck circumference. Utilizing the characteristics of Velcro that can be repeatedly opened and closed and is easy to adjust, it can adapt to necks of different thicknesses, and is firmly fixed while being easy to remove and convenient for daily cleaning and disinfection.

[0031] Specifically, the circulating cooling module includes a miniature circulating water pump 12 and an ice storage box 13. The ice storage box 13 is equipped with a heat exchange coil 14. The inlet and outlet of the heat exchange coil 14 are connected to the inlet and outlet of the cold compress water bag 8 through a circulating water pipe 15. The miniature circulating water pump 12 is installed on the circulating water pipe 15 and is connected to the human-machine interface control module. The core is to use ice to achieve continuous cooling. The whole system is a closed-loop water circulation structure: ice is placed in the ice storage box 13 for cooling, and circulating water is circulated through the built-in heat exchange coil 14. The miniature circulating water pump 12 drives the circulating water to flow continuously between the heat exchange coil 14 and the neck cold compress water bag 8, continuously delivering cold energy to the cold compress water bag 8 to maintain the cooling effect. The water pump can also adjust the circulation speed and the cooling range through the control module.

[0032] Specifically, a movable block 16 is fixedly connected to one end of the support cantilever 4, and a movable component 17 is fixedly connected to one end of the lifting slider 3. The movable block 16 is rotatably connected inside the movable component 17. A movable component 17 is fixed on the lifting slider 3, and a movable block 16 is fixed to the end of the support cantilever 4. The movable block 16 is locked in the movable component 17 and can rotate, thereby forming a hinged relationship between the support cantilever 4 and the lifting slider 3, so as to realize the free adjustment of the angle of the mouthwash head, adapt to the needs of different patients' mouth opening angles and wearing heights, and adjust to a more comfortable use position.

[0033] Specifically, the cold compress water bag 8 is a medical-grade elastic silicone water bag. The side of the cold compress water bag 8 closest to the neck skin has a skin-friendly absorbent cotton layer 21. The skin-friendly absorbent cotton layer 21 is detachably bonded to the cold compress water bag 8. It is made of medical-grade elastic silicone, meets medical safety standards, can bend to fit the contour of the neck, has good elasticity and is not easily damaged. The skin-friendly layer close to the skin has a replaceable skin-friendly absorbent cotton layer 21, which can absorb the condensation produced by the cold compress, prevent the skin from getting wet and cold, and improve comfort. The detachable bonding makes it easy to replace, and it is more hygienic to replace it after one person. It is also easy to clean and disinfect the water bag for reuse.

[0034] Specifically, the human-computer interaction control module includes a Bluetooth control unit 22 and a touch screen 23. The Bluetooth control unit 22 can establish a communication connection with a mobile smart terminal to achieve remote control. The core control part has a built-in touch screen 23 and also adds a Bluetooth control unit 22, supporting two control methods: it can be operated directly on the device touch screen, or it can be connected to mobile smart terminals such as mobile phones and tablets to remotely adjust parameters such as drug delivery speed, water temperature, and cold compress temperature. This facilitates remote operation by medical staff and eliminates the need for patients to get up and manually adjust the parameters, thus meeting the postoperative care needs of bedridden patients.

[0035] Specifically, the lower end of the mouthwash head shell 5 is also provided with a reflux hole 24, which is connected to a flexible return fluid tube 25. The other end of the flexible return fluid tube 25 is connected to a waste fluid collection chamber 26 located below the neck support base 1, forming a mouthwash reflux collection structure. The additional reflux hole 24 at the lower end of the mouthwash head allows the used mouthwash waste fluid in the mouth to be directly drained into the waste fluid collection chamber 26 below the neck support base 1 for storage through the flexible return fluid tube 25. This eliminates the need for patients to bend down to spit out waste fluid and prevents waste fluid from flowing out of the mouth and soiling clothes and bedding. It is very friendly to bedridden patients who have had tubes removed. The entire nursing process does not require getting up and does not soil clothes, solving the inconvenience of postoperative patients spitting out fluid on their own.

[0036] Specifically, the waste liquid collection chamber 26 is fixed to the lower side of the neck support base 1 by a detachable buckle 27. The side wall of the waste liquid collection chamber 26 is equipped with a drain valve 28, which is fixed to the lower side of the neck support base 1 by a detachable buckle 27. It is easy to disassemble and assemble. When it is full, it can be directly removed and emptied for cleaning. It is also convenient for disinfection and reuse. The drain valve 28 installed on the side wall allows the waste liquid to be discharged directly by opening the valve. It can be cleaned without completely disassembling the chamber, making the operation simpler and meeting the needs of medical staff for rapid cleaning.

[0037] In this implementation plan, medical staff pre-fill the prepared throat-soothing / conditioning medication into the storage compartment 9 of the low-speed quantitative drug delivery module and close the sealing cap; they then activate the electric heating element 11 via the human-machine interface control module to heat the medication to a preset comfortable human temperature (generally 36-37℃), and automatically maintain the temperature after heating; for cold source preparation, pre-frozen ice is added to the ice storage box 13 of the circulating cooling module, the ice storage box 13 door is closed, and the connection of the circulating water pipe 15 is checked for leaks; for hygiene pretreatment, a brand new skin-friendly absorbent cotton layer 21 is replaced and bonded firmly. Position the cold compress water bag 8 on the skin-friendly side; secure the cleaned waste fluid collection chamber 26 to the underside of the neck brace base 1 using the detachable buckle 27, and close the drain valve 28; after the patient is seated or lying down, the medical staff places the U-shaped neck brace base 1 on the patient's neck, adjusts the position so that the cold compress water bag 8 is aligned with the patient's pharyngeal skin, wraps the two straps 18 around the back of the neck, adjusts the length of the straps 18 according to the patient's neck circumference, press the hook side 19 and the loop side 20 of the Velcro to complete the fixation, the tightness should be such that one finger can be inserted, to avoid compressing the airway; adjust the position of the gargling head by loosening and raising / lowering it. The locking structure of slider 3 allows for sliding adjustment of the overall height of the support cantilever 4 and the mouthwash head housing 5 along the vertical guide rail 2. Once adjusted, slider 3 is locked. Rotating the support cantilever 4 causes the movable block 16 to rotate within the movable part 17, adjusting the pitch angle of the mouthwash head housing 5. Finally, the mouthwash head housing 5 is smoothly placed into the patient's oral vestibule, conforming to the oral cavity contour for positioning, without the patient needing to consciously hold it in their mouth. Parameter selection allows medical staff to directly touch the device's touch screen 23 to set the dispensing rate for low-speed quantitative drug administration (generally 0.5%) based on the patient's degree of dry mouth and sore throat. The target temperature of the cold compress water bag 8 (5-2 ml / min) can also be set remotely via Bluetooth control unit 22 connected to a mobile phone / tablet, without needing to get close to the patient; after the pre-start check settings are completed, a 10-second pre-run is started to check whether the liquid flow is smooth and whether the water circulation is normal. After confirming that there is no jamming or leakage, the formal treatment can begin; the oral gargling treatment micro-peristaltic pump 10 runs at a low speed according to the preset speed, stably delivering the warmed medicine in the medicine storage tank 9 to the gargling head shell 5 through the flexible liquid guide tube 7, with the medicine flowing from a diameter of 0.8-1.The 2mm outlet hole 6 slowly and evenly flows out, continuously moisturizing the patient's mouth and throat, achieving the effects of oral cleaning and pain relief; the pharyngeal cold compress conditioning micro circulating water pump 12 starts according to the preset power, driving the circulating water to circulate in a closed loop between the heat exchange coil 14 of the ice storage box 13 and the cold compress water bag 8. The ice continuously cools the circulating water in the heat exchange coil 14, and the cold energy is continuously delivered to the cold compress water bag 8 that fits the pharynx through the circulating water pipe 15, constricting the pharyngeal blood vessels and reducing edema and pain after intubation. The cooling range can be changed by adjusting the water pump speed; the waste liquid is automatically collected. The used mouthwash in the mouth flows into the return hole 24 along the mouthwash head shell 5, and is automatically drained into the waste liquid collection chamber 26 under the neck support base 1 through the flexible return liquid pipe 25 for storage. The patient does not need to bend over to spit out the liquid, and will not soil clothes and bedding. The entire process can be carried out while maintaining a bed-lying position; when After the waste fluid collection chamber 26 has accumulated a certain amount, medical staff can choose one of two cleaning methods depending on the situation: First, directly open the drain valve 28 on the side wall of the waste fluid collection chamber 26 to drain the waste fluid into the receiving container, then close the drain valve 28 after emptying. This operation is quick. Second, loosen the detachable buckle 27, directly remove the entire waste fluid collection chamber 26 from the neck support base 1, empty the waste fluid, disinfect, and then reinstall and fix it. After the treatment, first turn off the micro-peristaltic pump 10 and the micro-circulating water pump 12, loosen the Velcro hook side 19 and the Velcro loop side 20 to remove the neck support base 1, remove and discard the skin-friendly absorbent cotton layer 21, disconnect all connecting pipes, disinfect and sterilize the mouthwash head shell 5, flexible guide tube 7, flexible return tube 25, and waste fluid collection chamber 26, drain the residual water from the cold compress water bag 8 and the circulating water pipe 15, and store them in a dry place for the next use.
