Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical supplies technology, and in particular to a clean and dirty compartment dual-cup integrated mouthwash pot. Background Technology
[0002] In clinical practice, the incidence of chemotherapy-related oral mucositis in cancer patients ranges from 20% to 80%, with an even higher incidence in hematological malignancy patients and transplant recipients. A crucial measure for preventing stomatitis is the effective implementation of oral hygiene practices. However, actual clinical surveys have revealed that 60-70% of patients have poor oral hygiene habits. Poor oral hygiene easily leads to the rapid proliferation of bacteria in the mouth, causing local inflammation, ulcers, and other oral infections, affecting patients' quality of life and disease recovery. For hematological malignancy patients undergoing chemotherapy and transplant recipients, a daily mouthwash cup is essential. Effective recording of mouthwash acquisition and frequency is crucial, as the disposal of wastewater in the trash can produces odors and an unpleasant experience, also posing a risk of infection. Therefore, there is an urgent need for a mouthwash bottle with a separate clean and dirty compartment to help patients more conveniently, quickly, and comfortably maintain good oral hygiene habits. Utility Model Content
[0003] To address the aforementioned technical deficiencies, this invention provides a dual-cup integrated mouthwash pot with separate clean and dirty compartments, which can seal the clean water cup and the dirty water cup, and can monitor and record the number of times the patient rinses their mouth.
[0004] This utility model discloses a clean and dirty compartment dual-cup integrated mouthwash pot, including a base and a clean water cup and a dirty water cup. The clean water cup and the dirty water cup are arranged side by side on the base. The lids of the clean water cup and the dirty water cup are hinged to the top of the clean water cup and the dirty water cup. The clean water cup and the dirty water cup are provided with buckles on the opposite side of the hinge for locking the lids of the clean water cup and the dirty water cup. The buckles are press-to-open structures. A counter is provided on the outer wall of the clean water cup. The counting button of the counter is located inside the buckle of the clean water cup, and the display area and reset button of the counter are located outside the buckle.
[0005] The buckle has the following structure: it includes a swing rod, the middle part of which is rotatably connected to a connecting seat on a clean water cup and a dirty water cup via a pin. The upper end of the swing rod is provided with a buckle facing the cup lid, and the lower end of the swing rod is a pressing part. The counter button on the clean water cup is located inside the pressing part of the buckle of the clean water cup. When the pressing part is pressed until the cup lid is opened, the counter counts once.
[0006] A connector is provided inside the water cup, and a straw is fixed on the connector. The lower end of the straw extends to the bottom of the water cup. In its natural state, the upper end of the straw extends to the outside of the water cup. When the lid of the water cup is closed, the upper end of the straw is pressed into the inside of the water cup.
[0007] An intermediate body is provided on the base between the clean water cup and the dirty water cup. The intermediate body and the base are an integral structure. A recessed receiving cavity is provided on the top of the intermediate body. A cover is connected to one side wall of the top of the intermediate body by a hinge. A buckle is provided on the opposite side wall of the intermediate body. The buckle is used to lock the cover.
[0008] The middle body and base below the receiving cavity are hollow to form an assembly cavity. A battery and controller are installed in the assembly cavity. A liquid level sensor is installed at the upper end of the sewage cup and a liquid level sensor is also installed at the bottom of the clean water cup. The liquid level sensors are all connected to the controller. A speaker is installed on the side wall of the assembly cavity and is connected to the controller.
[0009] A transparent observation window is provided on the side wall of the water cup, and the transparent observation window is provided with liquid level scale.
[0010] Handles can be provided on the base or the middle section for easy carrying.
[0011] The water cup and the dirty water cup can be different colors for better differentiation.
[0012] In addition, the cup body of the water cup can be made of a temperature-sensitive color-changing material. The water inside the cup keeps the cup body material at the same temperature as the water, and the material displays different colors according to the water temperature. In actual use, if the water temperature is too high, the cup body color can alert the patient to avoid burns. Furthermore, in situations where cold rinsing is necessary, the cold rinsing solution in the cup can also have a color indicator, making it easier for patients to obtain temperature information. For example, in clinical settings such as transplant patients requiring special medications and needing to rinse with ice water, the cup color can be used to monitor the water temperature promptly, preventing burns caused by unintentional actions. Conversely, if the cup contains lukewarm water, and the nurse notices that the cup color is not the color corresponding to ice water, timely educational intervention can be provided.
[0013] The present invention provides a clean and dirty compartment dual-cup integrated mouthwash pot that can detect and record the number of times a patient rinses their mouth. At the same time, the dirty water from rinsing can enter the dirty water cup and be sealed, making it easy for medical staff to empty later. It will not produce odors or breed bacteria in the ward, thus reducing the risk of infection for patients. Attached Figure Description

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0019] Example 1:
[0020] like Figures 1-4 As shown, this utility model discloses a clean and dirty compartment dual-cup integrated mouthwash pot, including a base 1, a clean water cup 2, and a dirty water cup 3. The clean water cup 2 and the dirty water cup 3 are arranged side by side on the base 1. A cup lid 4 is provided on the top of the clean water cup 2 and the dirty water cup 3 through a hinge 10. A buckle 5 is provided on the clean water cup 2 and the dirty water cup 3 on the opposite side of the hinge 10 to lock the cup lid 4 on the clean water cup 2 and the dirty water cup 3. The buckle 5 is a press-to-open structure. A counter 6 is provided on the outer wall of the clean water cup 2. The counting button of the counter 6 is located inside the buckle 5 of the clean water cup 2, and the display area 61 and the reset button 62 of the counter 6 are located outside the buckle 5.
[0021] A clean water cup 2 and a dirty water cup 3 are mounted on a base 1, and the two cups can be plugged into the base 1. The clean water cup 2 contains clean water for patients to rinse their mouths. Both the clean water cup 2 and the dirty water cup 3 have lids 4, which can be fitted with sealing strips. The lids 4 are sealed to the clean water cup 2 and the dirty water cup 3 and locked in place by clips 5. When rinsing, patients simply open the lid 4 of the clean water cup 2 to drink water, and then open the lid 4 of the dirty water cup 3 to spit the dirty water into it. The lid 4 is then closed, allowing the dirty water to remain in the dirty water cup 3. This process prevents odors and bacterial growth in the ward. The dirty water cup 3 can be emptied and cleaned by medical staff afterward. A counter 6 is installed on the side wall of the clean water cup 2 to monitor and record the number of times patients rinse their mouths. For ease of use, the counting button of the counter 6 is located inside the latch 5 of the water cup 2. When the patient opens the lid 4 of the water cup 2 to rinse their mouth, they need to press the latch 5 first to open the lid 4. When they press the latch 5 to open the lid 4, they will simultaneously press the counting button, and the count value on the counter 6 will increase by 1, which is considered as one rinse. The specific structure and principle of the counter 6 are existing technologies, and the counter 6 is a commercially available product. Therefore, this application does not limit the specific structural form of the counter 6.
[0022] Of course, in actual use, a patient might drink water around cup lid 4, and counter 6 will also record one rinsing. Medical staff can therefore consider drinking water as rinsing.
[0023] The buckle 5 has the following structure: it includes a swing rod, the middle part of which is rotatably connected to the connecting seat 9 on the clean water cup 2 and the dirty water cup 3 via a pin. The upper end of the swing rod is provided with a buckle part 51 facing the cup lid 4, and the lower end of the swing rod is a pressing part 52. The counting button of the counter 6 on the clean water cup 2 is located inside the pressing part 52 of the buckle 5 of the clean water cup 2. When the pressing part 52 is pressed until the cup lid 4 is opened, the counter 6 counts once.
[0024] The latch 5 is a swing-type latch, meaning that in its natural state, the latch 51 at the upper end of the swing rod can hook onto the cup lid 4, sealing and locking the cup lid 4 with the clean water cup 2, the dirty water cup 3, etc. The specific forms of the latch 51 and the cup lid 4 are known and not specifically limited here. When the pressing part 52 is pressed inward, the latch 51 moves outward, disengaging from the cup lid 4 and opening it. During this process, the pressing part 52 simultaneously presses inward and simultaneously presses the counting button of the counter 6, causing the counter 6 to count once.
[0025] A connector 13 is installed inside the water cup 2, and a straw 14 is fixed to the connector 13. The lower end of the straw 14 extends to the bottom of the water cup 2, and in its natural state, the upper end of the straw 14 extends to the outside of the water cup 2. When the lid 4 of the water cup 2 is closed, the upper end of the straw 14 is pressed into the water cup 2. With the straw 14 inside the water cup 2, when the lid 4 is open, the upper end of the straw 14 extends to the outside of the water cup 2 due to its own restoring force, making it convenient for the patient to drink and rinse their mouth through the straw 14. When the lid 4 is closed, the straw 14 is inside the water cup 2, preventing water from overflowing.
[0026] An intermediate body 7 is provided on the base 1 between the clean water cup 2 and the wastewater cup 3. The intermediate body 7 is an integral structure with the base 1. A recessed receiving cavity 11 is provided on the top of the intermediate body 7. A cover 8 is connected to one side wall of the top of the intermediate body 7 by a hinge 10. A buckle 5 is provided on the opposite side wall of the intermediate body 7 to lock the cover 8. The receiving cavity 11 is provided inside the intermediate body 7 on the base 1. According to actual needs, a toothbrush, dental floss, etc. can be placed in the receiving cavity 11. This design makes the entire device easy to carry and helps patients develop oral hygiene habits such as brushing their teeth, rinsing their mouths, and using dental floss.
[0027] The intermediate body 7 and the base 1 below the receiving cavity 11 are hollow to form an assembly cavity 12. A battery and a controller are installed in the assembly cavity 12. A liquid level sensor 15 is installed at the upper end of the sewage cup 3 and a liquid level sensor 15 is also installed at the bottom of the clean water cup 2. The liquid level sensors 15 are all connected to the controller. A speaker is installed on the side wall of the assembly cavity 12 and the speaker is connected to the controller.
[0028] A level sensor 15 is installed at the upper end of the wastewater cup 3. When the level sensor 15 detects a high level, it transmits a signal to the controller, which then controls the speaker to issue a prompt such as "Wastewater full" or "Please empty wastewater." It can also emit a simple warning sound to remind patients and medical staff to pay attention to the amount of wastewater in the wastewater cup 3 and empty it promptly. Similarly, a level sensor 15 is installed at the lower end of the clean water cup 2. When the water level in the clean water cup 2 drops to a low level, the level sensor 15 transmits a signal to the controller, which then controls the speaker to issue a prompt such as "Please add clean water." It can also emit a simple warning sound to remind patients and medical staff to add clean water promptly. The battery can be a dry cell battery or a rechargeable battery to provide power to the controller, speaker, and level sensor 15.
[0029] The battery, controller, speaker, etc. inside the assembly cavity 12 in the picture are not shown.
[0030] In other embodiments, a transparent observation window with liquid level markings can be provided on the side wall of the water cup 2. The patient can independently observe the amount of water in the water cup 2, while medical staff can also determine the amount and frequency of rinsing by checking the liquid level markings in the water cup 2, thus determining whether rinsing is thorough.
