Description

Technical Field

[0001] This application relates to the field of medical supplies technology, specifically a waste liquid collection tank with a liquid level alarm function. Background Technology

[0002] In clinical medical procedures such as surgery, childbirth, and drainage, a large amount of infectious liquid waste is generated. If this waste is not handled properly, it can easily cause environmental pollution and spread viruses. Therefore, special waste collection tanks are needed for safe and sealed collection and temporary storage.

[0003] Currently, most waste liquid collection tanks used in medical institutions have an openable and closable structure. After a collection bag is placed inside the tank, waste liquid is collected. However, once the lid is closed, medical staff cannot promptly observe the volume of waste liquid inside the tank. They must rely entirely on medical staff to frequently open the lid manually to observe and judge the liquid level. This method not only increases the operational burden but also raises the risk of contact with potential sources of infection. At the same time, manual judgment is extremely inaccurate and can easily lead to overfilling and overflow, causing pollution. Therefore, there is an urgent need for a waste liquid collection tank that can achieve non-contact, accurate liquid level monitoring and is safe and convenient to operate. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model discloses a waste liquid collection tank with a liquid level alarm function. This utility model can not only realize accurate automatic early warning of liquid level through pressure sensing and warning light linkage, but also effectively prevent splashing of waste liquid when it is poured, and ensure the airtightness of the tank.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A waste liquid collection tank with a liquid level alarm function includes an outer tank body and further includes:

[0007] The inner barrel is detachably installed inside the outer barrel and is used to hold the collection bags;

[0008] The pressure sensor controller is located at the bottom of the inner cavity of the outer barrel and is used to monitor the total weight of the inner barrel and its contents.

[0009] Warning lights are located on the outside of the outer barrel and are electrically connected to the pressure sensor controller to issue a warning signal when the weight detected by the pressure sensor controller reaches a preset threshold.

[0010] The sealing cap is detachably installed on the upper part of the outer barrel to seal the outer barrel and the inner barrel. The sealing cap has a collection port that communicates with the inner barrel, and an openable and closable cover is provided above the collection port.

[0011] Furthermore, an annular step is provided on the outer edge of the upper end of the inner barrel, and a pressure ring is detachably installed inside the annular step for expanding the opening of the collection bag and pressing it firmly onto the annular step.

[0012] Furthermore, the upper part of the inner wall of the inner barrel has a number of grooves with open tops evenly distributed, and a handle that can be rotatably connected to the groove or flipped out from the open top of the groove.

[0013] Furthermore, multiple buckles are evenly distributed on the upper part of the outer wall of the outer barrel, and multiple hooks are provided on the outer wall of the sealing cap to engage with the buckles one by one.

[0014] Furthermore, the upper end face of the outer barrel is provided with an outer sealing ring surrounding the opening of the outer barrel, and the lower surface of the sealing cover is provided with an annular groove that matches the outer sealing ring.

[0015] Furthermore, the lower surface of the sealing cap is provided with an inner sealing ring that corresponds to and fits the upper end face of the inner barrel and makes an interference fit with the upper end face of the inner barrel.

[0016] Furthermore, the upper surface of the sealing cap is provided with a groove, the collection port is provided on the bottom surface of the groove, and the movable cap is movably installed in the groove.

[0017] Furthermore, a flow guiding mechanism is detachably installed inside the collection port to receive waste liquid and change its flow direction to prevent splashing.

[0018] Furthermore, the diversion mechanism includes:

[0019] A cone-shaped bucket, with its large-diameter end inserted into the collection port;

[0020] The guide plate is located below the small-diameter end of the conical bucket, with its lower end inclined toward the inner wall of the inner barrel.

[0021] The connecting rod has one end connected to the inner wall of the small-diameter end of the conical bucket, and the other end connected to the guide plate.

[0022] Furthermore, a battery for powering the pressure sensor controller and warning lights is embedded in the bottom surface of the outer barrel.

[0023] Compared with the prior art, the beneficial effects of this application are:

[0024] By monitoring the total weight of the inner tank in real time through a pressure sensor controller located at the bottom of the outer tank, the warning light on the outside can be automatically triggered when the waste liquid reaches the preset capacity. This not only achieves non-contact measurement, avoiding direct contact between the sensor and the waste liquid and improving the reliability and lifespan of the system, but also completely changes the outdated method of relying on manual observation, effectively preventing waste liquid spillage accidents, reminding timely replacement, and improving the safety management level of the medical environment.

[0025] By setting up inner and outer sealing rings, a double seal is achieved between the outer and inner barrels, ensuring excellent airtightness of the barrel when closed, and effectively preventing liquid leakage and the spread of harmful odors.

[0026] The combination of the ring step and the pressure ring can quickly and securely fix the opening of the collection bag, preventing it from slipping off.

[0027] The sealing cap with snap fasteners and the handle on the inner tub allow for efficient loading and unloading of the inner tub, facilitating thorough cleaning and disinfection afterwards.

[0028] A detachable flow guiding mechanism is installed inside the collection port, consisting of a conical hopper and an inclined guide plate. After the waste liquid is poured in, it is collected in the conical hopper and then the flow direction is changed by the guide plate, allowing it to flow smoothly down the side wall of the inner tank. This greatly reduces splashing and bubbles generated when the liquid impacts the bottom of the tank, reduces the potential risk of cross-contamination, and keeps the area around the tank clean.

[0029] This invention not only achieves precise automatic early warning of liquid level through pressure sensing and warning light linkage, but also effectively prevents splashing of waste liquid during pouring and ensures the airtightness of the container. Furthermore, this invention significantly improves ease of use, safety, and maintenance efficiency through quick-release sealing caps, flip-up handles, and pressure ring fixing methods, fully meeting the higher requirements of modern medical environments for waste liquid collection and treatment.

[0040] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0041] Please refer to the instruction manual appendix. Figure 1-5 This utility model provides a technical solution:

[0042] Example 1: A waste liquid collection tank with a liquid level alarm function includes an outer tank 1 and an inner tank 2. The inner tank 2 is detachably installed inside the outer tank 1, and the outer diameter of the inner tank 2 is adapted to the inner diameter of the outer tank 1. A collection bag 3 is placed inside the inner tank 2. A pressure sensor controller 1.2 for monitoring the total weight of the inner tank 2 and its contents is provided at the bottom of the inner cavity of the outer tank 1. An alarm light 1 is provided on the outer wall of the outer tank 1, which is electrically connected to and controlled by the pressure sensor controller 1.2. 1. The pressure sensor controller 1.2 reads the pressure sensor data through the microcontroller inside the pressure sensor controller 1.2 and controls the color change of the warning light 1.1. The pressure sensor controller 1.2 monitors the total weight of the inner tank 2 and its contents in real time. As the inner tank 2 collects waste liquid, the weight of the inner tank 2 increases step by step. When the monitored weight reaches the preset threshold, the pressure sensor controller 1.2 sends a control signal, and the warning light 1.1 lights up to issue a warning signal, thereby reminding medical staff to deal with the waste liquid in the inner tank 2 in a timely manner.

[0043] To achieve a seal between the outer barrel 1 and the inner barrel 2, a sealing cover 5 is detachably installed on the upper part of the outer barrel 1. Specifically, multiple buckles 1.5 are evenly distributed on the upper part of the outer side wall of the outer barrel 1, and multiple hooks 5.6 are provided on the outer side wall of the sealing cover 5, which are corresponding to and engage with the buckles 1.5. A groove 5.4 is provided on the upper surface of the sealing cover 5, and a collection port 5.1 corresponding to and communicating with the inner barrel 2 is opened on the bottom surface of the groove 5.4. An openable and closable movable cover 5.2 is provided in the groove 5.4. The movable cover 5.2 can be opened and closed by means of a hinged connection, or it can be opened and closed by means of an existing foot pedal structure, that is, it is connected by a foot pedal linkage mechanism.

[0044] In Example 2, to achieve the snap-fit ​​sealing of the sealing cap 5 with the outer barrel 1 and the inner barrel 2, the upper end face of the outer barrel 1 is provided with an outer sealing ring 1.4 surrounding the opening of the outer barrel 1, and the lower surface of the sealing cap 5 is provided with an annular groove 5.5 that matches the outer sealing ring 1.4. The lower surface of the sealing cap 5 is provided with an inner sealing ring 5.3 that matches the upper end face of the inner barrel 2. As the sealing cap 5 is snapped in, the outer sealing ring 1.4 is press-fitted into the annular groove 5.5, thus sealing the outer barrel 1. The inner sealing ring 5.3 press-fits against the upper end face of the inner barrel 2, thus sealing the inner barrel 2.

[0045] In Example 3, in order to enable the collection bag 3 to expand stably and efficiently within the inner barrel 2, facilitating subsequent collection and treatment of waste liquid, an annular step 2.1 is provided on the outer edge of the upper end of the inner barrel 2. A pressure ring 2.2 is detachably installed inside the annular step 2. When the collection bag 3 is placed inside the inner barrel 2, the bag opening of the collection bag 3 is expanded through the opening of the inner barrel 2, and the outer edge of the bag opening of the collection bag 3 is located on the annular step 2.1. Then, the pressure ring 2.2 is used to lock the bag opening onto the annular step 2.1, thereby pressing and limiting the bag opening of the collection bag 3.

[0046] In Example 4, to facilitate the disassembly of the inner barrel 2, multiple grooves 2.4 with open tops are evenly distributed on the upper part of the inner wall of the inner barrel 2. A handle 2.3 is rotatably connected to the groove 2.4, which can be stored in the groove or flipped out from the open top of the groove 2.4. When the collection bag 3 is installed, the handle 2.3 is flipped over and stored in the groove 2.4. The opening of the collection bag 3 can be smoothly pressed and limited by the pressure ring 2.2. When it is necessary to remove it from the inner barrel 2, simply seal the collection bag 3 and remove it, then flip the handle 2.3 out, and the inner barrel 2 can be quickly pulled out through the handle 2.3.

[0047] In Example 5, when waste liquid is poured into the inner tank 2 through the collection port 5.1, the vertical drop of waste liquid into the inner tank 2 not only causes rebound and splashing, but also affects the stability of the inner tank 2 and the outer tank 1. To prevent splashing, a flow guiding mechanism 4 is detachably installed inside the collection port 5.1 to receive the waste liquid and change its flow direction to prevent splashing. Specifically, the flow guiding mechanism 4 includes a conical bucket 4.1, a connecting rod 4.2, and a guide plate 4.3. The large-diameter end of the conical bucket 4.1 is inserted into the collection port 5.1 to... Ensure that the outer wall of the conical hopper 4.1 fits snugly with the collection port 5.1, and that the inner wall of the collection port 5.1 is parallel to the outer wall of the conical hopper 4.1. The guide plate 4.3 is located below the small-diameter end of the conical hopper 4.1, with its lower end inclined toward the inner wall of the inner barrel 2. One end of the connecting rod 4.2 is connected to the inner wall of the small-diameter end of the conical hopper 4.1, and the other end is connected to the guide plate 4.3. Multiple guide plates 4.3 can be provided so that the waste liquid can flow evenly to the inner wall of the inner barrel 2 through multiple guide plates 4.3 and flow down through the inner wall.
