Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a self-sensing urine collection head and urine collection device. Background Technology

[0002] Urine collectors are primarily used to collect naturally excreted urine, and are particularly suitable for people with limited mobility or who cannot control urination, such as bedridden patients, the elderly, or patients with specific medical conditions. These collectors typically consist of a diaper-like or tubular collection head that fits snugly against the body, and a liquid delivery system that connects to an external storage container. This design effectively guides urine from the user's body into the storage container, avoiding potential skin irritation or other health problems caused by direct skin contact.

[0003] In addition, some high-end products are equipped with a liquid pump system to accelerate the urine transfer process and ensure that urine does not flow back, thus providing a more hygienic and comfortable user experience.

[0004] However, in practical applications, current urine collection devices still face several technical challenges, affecting user experience and product usability. One significant issue is that after collecting urine, the wearer often needs to manually control the pump to initiate the aspiration process. This not only increases the user's workload but is also difficult to achieve in a timely manner, especially for those with limited physical mobility. The inability to initiate aspiration promptly may lead to urine overflow or excessive accumulation inside the collection device, increasing the frequency of replacement and potentially causing health risks such as skin infections. Furthermore, residual urine can become an ideal environment for bacterial growth, further threatening the user's health and safety. Therefore, developing a self-sensing urine collection head and device that can automatically sense and promptly aspire to collect urine is crucial, aiming to address the inconvenience and associated risks of manual control.

[0035] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] It should be noted that the terms center, up, down, left, right, vertical, horizontal, inner, and outer, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when placing the technical product. They are used solely for the convenience of describing the technology and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the technology. Furthermore, the terms horizontal, vertical, and suspended do not mean that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, horizontal simply means that its direction is more horizontal than vertical, not that the structure must be completely horizontal, but can be slightly tilted.

[0039] Please see Figure 1-6 The self-sensing urine collection head includes a soft shell 1 with a surface that allows urine to enter, a suction tube 2 extending into the interior of the soft shell 1, and a liquid sensing unit disposed inside the soft shell 1.

[0040] The liquid sensing unit is located inside the soft casing 1 and is connected to the external main control module via a signal wire. It sends an electrical signal to the main control module after the liquid inside the soft casing 1 comes into contact with the liquid sensing unit. The soft casing 1 can be made of silicone, TPU, or other flexible materials. The suction tube 2 is a rigid or flexible tubular structure, made of medical-grade plastic or rubber, used to connect to an external suction pump. The liquid sensing unit can be an electrode sensor, a humidity sensor, or an optical sensor, etc., which triggers an electrical signal upon contact with urine. The presence of urine is monitored through physical contact. The three components are functionally linked through the spatial arrangement inside the casing: after urine enters the casing through the inlet, it first contacts the liquid sensing unit, triggering a signal, and then is pumped to the urine storage tank 6 through the suction tube 2.

[0041] To prevent urine leakage during collection, a liquid accumulator 3 is installed inside the soft casing 1. The liquid sensing unit is located between the liquid accumulator 3 and the soft casing 1. A transition housing 4 is provided on the surface of the soft casing 1. The transition housing 4 has a channel inside for the signal wire connecting the suction pipe 2 and the liquid sensing unit to pass through. The liquid accumulator 3 can be a sponge layer, porous material, or a reservoir, used to temporarily store urine. The liquid accumulator 3 is installed inside the soft casing 1, with its upper layer communicating with the urine inlet and its lower layer communicating with the suction pipe 2. The liquid sensing unit is embedded in the gap between the accumulator 3 and the casing, or fixed below the accumulator 3 by a bracket, ensuring that the urine will contact the sensing unit when it reaches a preset height. By placing the sensing unit below the accumulator 3, it ensures that the pumping is triggered only after a certain amount of urine has accumulated, avoiding frequent pump starts due to small amounts of urine contacting the sensing unit, reducing energy waste and extending equipment life.

[0042] Considering the electronic components inside the adapter housing 4, to prevent damage to these components due to urine leakage, an isolation plate is provided between the adapter housing 4 and the soft casing 1. This isolation plate forms an independent chamber with the adapter housing 4. The surface of the isolation plate has an adapter unit connected to the liquid sensing unit. This adapter unit can be connected to an external control unit via a signal wire. The adapter housing 4 can be made of rigid plastic or metal, with internal openings or conduits to accommodate the suction tube 2 and the signal wire. The suction tube 2 is connected to the adapter housing 4 via a sealing ring, and the signal wire passes through the channel via a waterproof connector. Centralized management of the outlets of the suction tube 2 and the signal wire through the adapter housing 4 simplifies the external pipeline layout, enhances the sealing between the casing and external equipment, reduces the risk of urine leakage, and improves the overall structural compactness and reliability. The isolation plate can be a plastic partition, metal mesh, or sealing membrane, and is fixed to the adapter housing 4 by clips, screws, or welding.

[0043] To further explain the above technical content, a urine collection system is now disclosed, which includes a self-sensing urine collection device, comprising: a liquid extraction component 5, a urine storage tank 6 communicating with the liquid extraction component, a liquid level sensing component 7 capable of sensing the liquid level height in the urine storage tank 6, and a main control module.

[0044] It also includes a housing 8, the liquid pump is located inside the housing 8, the surface of the housing 8 is provided with an installation groove for the urine storage tank 6 to be installed, and the liquid level sensing component 7 is located in the installation groove.

[0045] Specifically, the liquid extraction assembly 5 includes a liquid extraction tube 2 extending into the interior of the soft housing 1, and a liquid extraction pump whose input end is connected to the liquid extraction tube 2. The pump can be a micro centrifugal pump, a diaphragm pump, or a pneumatic pump. The urine storage tank 6 is connected to the output end of the liquid extraction pump and can be a transparent or opaque container made of PP or PVC.

[0046] The liquid level sensing component 7 can be a common laser liquid level sensor. The urine storage tank 6 has a liquid inlet on its surface and a matching interface adapted to the liquid inlet in the mounting groove. The output end of the pump is connected to the matching interface through a pipe. When the urine storage tank 6 is installed in the mounting groove, the liquid inlet and the matching interface are connected.

[0047] In the above technical solution, the main control module receives a high-level signal from the liquid level sensor and controls the switching or speed of the pump via a relay or PWM. By integrating the functions of liquid extraction, urine storage, and liquid level monitoring, a closed-loop control system is formed. When urine inside the casing triggers the sensing unit to start the pump, the main control module automatically adjusts the extraction frequency or stops the pump based on the liquid level in the urine storage tank 6 and sends an alarm to the outside world to prevent the urine storage tank 6 from overflowing and to remind the wearer, thus achieving fully automated management of the entire process.

[0048] When the urine storage tank 6 is inserted, its inlet port automatically aligns with the outlet port to form a sealed passage. Preferably, the bottom of the urine storage tank 6 is designed with a flange, which triggers the outlet port to eject the sealing ring and complete the seal when inserted into the mounting slot. Through the standardized mounting slot and outlet port design, the urine storage tank 6 can be quickly replaced and sealed, reducing manual wiring or debugging time, while also facilitating cleaning and maintenance, and improving operational efficiency and hygiene.

[0049] The inlet can be a conical connector, flange, or threaded connector, and the mating interface must match the type of the inlet; the pipe can be a flexible hose or a rigid pipe, made of silicone or PVC. One end of the pipe at the output end of the pump is connected to the pump body, and the other end is welded or snapped to the mating interface in the mounting groove; when the urine storage tank 6 is installed, its inlet and mating interfaces can be sealed and connected by thread tightening, snap-fitting, or plugging. The mating interface can be designed as an L-shaped elbow to guide the liquid vertically into the urine storage tank 6.

[0050] In some embodiments, to further accurately sense the urine level in the urine storage tank 6, a liquid level sensor is provided inside the urine storage tank 6. The surface of the urine storage tank 6 and the mounting groove are provided with compatible electrical interfaces. When the urine storage tank 6 is installed in the mounting groove, the liquid level sensor can be connected to the main control module through the electrical interface. Together with the liquid level sensing component 7 outside the urine storage tank 6, the accurate measurement of the urine level can be effectively achieved. At the same time, to ensure accurate control of the urine collection head and reduce the mess of the device signal wires, the liquid extraction tube 2 is provided with an infusion channel for liquid to pass through and a signal wire channel that allows signal wires to pass through. Two-stage isolation and pressure reduction treatment of the signal wires can be selected according to the actual situation.

[0051] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "setup," "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
