Description

Technical Field

[0001] This utility model relates to the field of oral cancer care auxiliary components, specifically to an oral irrigation and collection device. Background Technology

[0002] Oral cancer is one of the most common malignant tumors of the head and neck, ranking sixth among malignant tumors. Most of them are squamous cell carcinomas. In the care of oral cancer, it is necessary to frequently use saline to rinse the patient's mouth because saline has anti-inflammatory and bactericidal effects. For patients with oral cancer, rinsing with saline can effectively relieve the condition and is beneficial for the later treatment of the disease. Moreover, rinsing with saline will not cause too much damage to the oral mucosa.

[0003] Currently, when using saline solution to rinse a patient's mouth, the usual procedure is to first hand the container of saline solution to the patient and pour it into their mouth, or directly assist the patient in injecting it into their mouth. Then, a basin or trash can is used to collect the wastewater after rinsing. This usually requires the participation of medical staff or caregivers at the bedside. The patient's level of self-participation during the procedure is low, making it very inconvenient and difficult to perform oral rinsing care. Utility Model Content

[0004] The purpose of this invention is to provide an oral rinsing and collection device to solve the above problems. By guiding the patient's mouth to the outer end of the flexible tube, physiological saline can be directly injected into the patient's oral cavity for rinsing through the water outlet. After the oral rinsing is completed, the waste liquid can be directly discharged into the waste collection tank through the inlet hopper and collected. This realizes the integration of oral rinsing and wastewater collection operations into one, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0009] Preferably, U-shaped handles are installed on the upper sides of both sides of the sludge storage tank body to facilitate holding and stabilizing the sludge storage tank body.

[0010] Preferably, the oral irrigation assembly includes a water tank body and a water outlet pipe. The bottom sides of the water tank body are detachably fixed above the rear top surface of the waste tank body via the disassembly and assembly assembly. The water outlet pipe is fixedly connected to the lower front part of the water tank body. The water outlet pipe is an L-shaped pipe. The bottom end of the vertical part of the water outlet pipe is suspended above the waste inlet and is coaxially and detachably assembled with a flexible connecting pipe for allowing the patient's mouth to hold the water in. The horizontal part of the water outlet pipe is equipped with a valve for controlling its opening and closing.

[0011] Preferably, the flexible connector is a corrugated pipe made of plastic, and the flexible connector is coaxially and detachably assembled around the bottom of the outlet pipe by means of tensioning.

[0012] Preferably, the top surface of the water tank body is vertically connected to a water injection pipe, and the top of the water injection pipe is coaxially and detachably assembled with a cover for controlling opening and closing. A transparent water level observation window is embedded in the front of the water tank body.

[0013] Preferably, each of the disassembly and assembly components includes a support rod and a fixing block. The support rod is vertically fixed to both sides of the bottom surface of the water storage tank body via a connecting sleeve. The rear outer periphery of the support rods on both sides has a limiting hole along the longitudinal direction near the bottom. The fixing block is vertically fixed to both sides of the rear outer periphery of the sludge storage tank body, and the top surface of the fixing block has a mating slot along the vertical direction. The mating slot corresponds one-to-one with the support rod and slides vertically. The rear outer periphery of the fixing block on both sides has a mounting hole along the longitudinal direction.

[0016] Using the above-mentioned oral irrigation and collection device, specifically in the process of oral cancer care, when rinsing the patient's mouth, since the oral irrigation component is assembled and installed on top of the waste collection component via the disassembly and assembly assembly, after the patient sits up on the bed, both the waste collection tank body of the waste collection component and the water storage tank body of the oral irrigation component are placed in front of the patient, and the sealing cap of the waste storage tank body is opened. By guiding the patient's mouth to the outer end of the flexible connector, physiological saline can be directly injected into the patient's mouth through the outlet pipe for rinsing. Moreover, after removing the sealing cap of the waste inlet, the waste liquid after oral rinsing can be directly ejected into the waste storage tank body through the waste inlet and collected. This combines the oral rinsing operation with the wastewater collection operation into one, increasing the patient's autonomy and reducing the workload of medical staff or caregivers, facilitating smooth rinsing of the patient's mouth. In the nursing operation, specifically regarding the combination and disassembly of the oral irrigation component and the waste collection component, when combining, the oral irrigation component can be detachably fixed to the top of the waste collection component by the vertical sliding engagement of the support rod and the mating slot, and the longitudinal sliding engagement of the limiting rod and the limiting hole. When disassembling, simply pull the handle outward and the limiting rod will disengage from the limiting hole by stretching the spring, allowing the support rod to vertically disengage from the mating slot and the oral irrigation component to be detached from the top of the waste collection component. The combination and disassembly of the oral irrigation component on the top of the waste collection component is simple and easy to implement, facilitating the quick combination of the oral irrigation component on the top of the waste collection component for oral irrigation care, and also facilitating the subsequent disassembly of the oral irrigation component and the waste collection component for their respective cleaning and maintenance.

[0017] The beneficial effects are as follows: 1. This utility model has an oral irrigation component installed on the top of the waste collection component by a disassembly and assembly assembly.

After opening the sealing cover of the waste storage tank body, the saline solution can be directly injected into the patient's oral cavity for rinsing by guiding the patient's mouth to the outer end of the flexible tube. After the oral cavity is rinsed, the waste liquid can be directly discharged into the waste storage tank body through the waste inlet bucket and collected. This realizes the integration of oral cavity rinsing and wastewater collection, which increases the patient's self-participation and reduces the workload of medical staff or caregivers, making it easier to perform oral cavity rinsing and care operations smoothly.

[0018] 2. The oral irrigation component can be detachably fixed to the top of the waste collection component by vertically sliding the support rod and the matching slot, and vertically sliding the limiting rod and the limiting hole. Simply pull the limiting rod out of the limiting hole to allow the support rod to vertically disengage from the matching slot, thus detaching the oral irrigation component from the top of the waste collection component. The assembly and disassembly of the oral irrigation component on the top of the waste collection component is simple and easy to implement. It is convenient to quickly assemble the oral irrigation component on the top of the waste collection component for oral irrigation care, and it is also convenient to disassemble the oral irrigation component and the waste collection component for separate cleaning and maintenance.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-7 As shown, this utility model provides an oral rinsing and collection device, including a waste collection component 3 and an oral rinsing component 1. Specifically, the waste collection component 3 includes a waste storage tank body 301 and a waste inlet hopper 306. The top of the waste storage tank body 301 is provided with a waste inlet hopper 306 for discharging waste liquid, and the waste inlet hopper 306 is coaxially and detachably assembled with a sealing plug 304 for controlling opening and closing. The rear sides of the top surface of the waste storage tank body 301 are both equipped with disassembly and assembly components 2, and the oral rinsing component 1 is detachably assembled to the upper rear side of the top surface of the waste storage tank body 301 through the disassembly and assembly components 2. The oral rinsing component 1 includes a water storage tank body 106 and a water outlet pipe 105. The bottom sides of the water storage tank body 106 are detachably fixed to the waste storage tank body through the disassembly and assembly components 2. Above the rear of the top surface of body 301, a water outlet pipe 105 is fixedly connected to the lower front of the water storage tank body 106. The water outlet pipe 105 is an L-shaped pipe. The bottom end of the vertical part of the water outlet pipe 105 is suspended above the waste inlet hopper 306 and is coaxially and detachably assembled with a flexible connecting pipe 107 for the patient to hold in their mouth to receive water. The horizontal part of the water outlet pipe 105 is equipped with a valve 104 for controlling the opening and closing. The purpose of this arrangement is to allow the patient's mouth to be guided to the outer end of the flexible connecting pipe 107 so that saline can be directly injected into the patient's oral cavity for rinsing by the water outlet pipe 105. After the oral cavity is rinsed, the waste liquid can be directly discharged into the waste storage tank body 301 through the waste inlet hopper 306 and collected. This realizes the integration of oral cavity rinsing and wastewater collection operations.

[0031] See Figures 1-5As shown, disassembly and assembly components 2 are installed on both sides of the rear top surface of the waste collection component 3. The disassembly and assembly components 2 are fixed to the bottom sides of the oral rinsing component 1, and the oral rinsing component 1 is detachably assembled to the upper rear top surface of the waste collection component 3 via the disassembly and assembly components 2. This allows the oral rinsing operation and wastewater collection operation to be combined into one using the waste collection component 3 and the oral rinsing component 1. Each disassembly and assembly component 2 includes a support rod 201 and a fixing block 204. The bottom sides of the water storage tank body 106 are vertically fixed via connecting sleeves 208. The support rods 201 on both sides have longitudinal limit holes 209 on their rear outer periphery near the bottom. The top rear side of the sludge storage tank body 301 has two vertically fixed fixing blocks 204, each with a vertically opening mating slot 205 on its top surface. These slots correspond one-to-one with the support rods 201 and slide vertically. The rear outer periphery of each fixing block 204 on both sides has longitudinally opening mounting holes 206, which are perpendicularly connected to their corresponding mating slots 205 and also connect to their corresponding limit holes. In longitudinal coaxial alignment 209, mounting holes 206 are all longitudinally coaxially fitted with limiting rods 207, and the front ends of the limiting rods 207 on both sides are longitudinally slidably fitted with the corresponding limiting holes 209. The rear ends of the limiting rods 207 on both sides extend out of the outer rear of the corresponding fixing block 204 and are coaxially fixed with handles 202. The portion of the limiting rod 207 located between the corresponding handle 202 and the outer rear of the fixing block 204 is coaxially fitted with springs 203, and the two ends of the springs 203 are respectively fixedly connected to the corresponding handle 202 and the outer rear of the fixing block 204. The purpose of this arrangement is that, by vertically sliding the support rod 201 of the assembly 2 with the mating slot 205 and longitudinally sliding the limiting rod 207 with the limiting hole 209, the oral irrigation assembly 1 can be detachably fixed above the top of the waste collection assembly 3. Only by pulling the limiting rod 207 out of the limiting hole 209 can the support rod 201 be vertically disengaged from the mating slot 205, thus removing the oral irrigation assembly 1 from the top of the waste collection assembly 3. The assembly and disassembly of the oral irrigation assembly 1 above the top of the waste collection assembly 3 is simple and easy to implement.

[0032] See Figures 1-5As shown, the waste collection component 3, oral irrigation component 1, and disassembly / assembly component 2 have been optimized as follows. Specifically, for the waste collection component 3, a drain port 307 is provided on the rear back of the waste storage tank body 301, and a plug 305 for controlling the opening and closing is coaxially and detachably installed on the drain port 307, so that the waste in the waste storage tank body 301 can be discharged to the outside through the drain port 307. At the same time, it is convenient to control the opening and closing of the drain port 307 through the plug 305. Optionally, the waste inlet hopper 306 is funnel-shaped and its top is flush with the top surface of the waste storage tank body 301, and the outer surface of the sealing plug 304 is sealed. The outer contour of the sealing plug 304 is adapted to the inner contour of the sludge inlet 306, and the lower outer periphery of the sealing plug 304 is coaxially and detachably connected to the lower inner periphery of the sludge inlet 306 by means of thread engagement. At the same time, the top surface of the sealing plug 304 is equipped with a force-applying handle 303 for easy gripping and rotating. This setting makes it easy to quickly assemble and disassemble the sealing plug 304 and the sludge inlet 306 by gripping and turning the force-applying handle 303. This allows wastewater to be directly discharged into the sludge storage tank body 301 through the sludge inlet 306 for collection. At the same time, it is easy to seal the sludge inlet 306 with the sealing plug 304 to prevent odor from escaping. Alternatively, U-shaped handles 302 are installed flat on the upper sides of both sides of the sludge tank body 301 to facilitate holding and stabilizing the sludge tank body 301. This arrangement allows patients to hold the U-shaped handles 302 firmly with both hands during use, providing a stable grip during flushing and stabilizing both the sludge tank body 301 and the water tank body 106.

[0033] Specifically, in the oral irrigation component 1, the flexible tube 107 is a corrugated plastic tube, and the flexible tube 107 is coaxially and detachably assembled with the bottom periphery of the water outlet tube 105 by means of tensioning. This design firstly facilitates the flexibility of the flexible tube 107 during use, making it convenient for patients to hold the outer end of the flexible tube 107 in their mouths and inject saline solution. At the same time, it facilitates the quick assembly and disassembly of the flexible tube 107 with the water outlet tube 105, thereby facilitating the replacement and disassembly of the flexible tube 107 for the hygienic use of different patients. Alternatively, a water injection pipe 102 is vertically fixedly connected to the top surface of the water tank body 106, and a cap 101 for controlling opening and closing is coaxially and detachably attached to the top of the water injection pipe 102, so that physiological saline can be added into the water tank body 106 through the water injection pipe 102 and sealed by the cap 101. A transparent water level observation window 103 is embedded in the front of the water tank body 106, so that the liquid level in the water tank body 106 can be viewed through the light-transmitting water level observation window 103. Specifically, regarding the assembly and disassembly assembly 2, the connecting sleeve 208 and the top of the support rod 201 are coaxially assembled by a threaded connection, so as to facilitate the quick assembly and disassembly of the support rod 201 at the bottom of the water tank body 106 using the connecting sleeve 208. Optionally, the mating slots 205 are all blind slots in the vertical direction, and the bottom end of the support rod 201 is in close contact with the bottom end of the corresponding mating slot 205. With this arrangement, as the support rod 201 slides vertically along the mating slot 205, when the limiting hole 209 slides down with the support rod 201 to align with the longitudinally coaxial limit rod 207, a clear indication can be provided by the bottom end of the support rod 201 contacting the bottom end of the corresponding mating slot 205.

[0034] Using the above structure, specifically in the process of oral cancer care, when performing oral irrigation on patients, since the oral irrigation component 1 is assembled and installed on top of the waste collection component 3 via the disassembly and assembly component 2, after the patient sits up on the bed, the waste collection tank body 301 of the waste collection component 3 and the water storage tank body 106 of the oral irrigation component 1 are both placed in front of the patient. After opening the sealing plug 304 of the waste collection tank body 301, by guiding the patient's mouth to the outer end of the flexible connector 107, saline can be directly injected into the patient's mouth for irrigation through the water outlet pipe 105. Moreover, after removing the sealing plug 304 of the waste inlet 306, the waste liquid after oral irrigation can be directly discharged into the waste storage tank body 301 through the waste inlet 306 and collected. This combines the oral irrigation operation with the wastewater collection operation into one, increasing the patient's autonomy and reducing the workload of medical staff or caregivers, making it easier to perform oral irrigation on patients. In the nursing operation, specifically regarding the combination and disassembly of the oral irrigation component 1 and the waste collection component 3, when combining, the oral irrigation component 1 can be detachably fixed to the top of the waste collection component 3 by vertically sliding the support rod 201 of the assembly component 2 with the mating slot 205 and longitudinally sliding the limiting rod 207 with the limiting hole 209. When disassembling, simply pull the handle 202 outward and the limiting rod 207 will disengage from the limiting hole 209 by stretching the spring 203. Then, the support rod 201 can be vertically disengaged from the mating slot 205, thus removing the oral irrigation component 1 from the top of the waste collection component 3. The combination and disassembly of the oral irrigation component 1 on the top of the waste collection component 3 is simple and easy to implement. It is convenient to quickly combine the oral irrigation component 1 on the top of the waste collection component 3 for oral irrigation care, and it is also convenient to disassemble the oral irrigation component 1 and the waste collection component 3 for separate cleaning and maintenance.
