Description

Technical Field

[0001] This invention relates to an automatic segmented urine sample collector for disposable urine samples, which is a convenient collector for collecting intermediate urine segments. It belongs to the field of urine collection technology, and specifically relates to a collector that uses a leak-proof device to guide urine flow and prevent urine leakage, and uses an automatic segmented collection device to automatically segment urine segments, making it convenient to collect intermediate urine segments. Background Technology

[0002] When patients need a urinalysis, a handheld disposable urine cup is typically used to collect a urine sample for laboratory testing to determine the condition. During sample collection, because the urethra may contain bacteria and other microorganisms, to avoid contamination, a portion of the urine is usually expelled before the cup is used to collect the remaining urine. Patients need to control the flow of urine to complete the collection, which is inconvenient. Furthermore, the opening of the disposable urine cup is small, often resulting in some urine leakage. Elderly people, children, or patients with mobility issues may find it difficult to accurately control the flow, leading to urine loss or insufficient collection, making the procedure inconvenient and affecting the urine sample analysis.

[0003] Publication No. CN110115600A discloses a segmented urine collection device for nursing use, including an extension bucket and a buffer chamber. The extension bucket is installed at the upper end of the buffer chamber and communicates with the buffer chamber. The opening area of ​​the upper end face of the extension bucket is larger than the inner horizontal area of ​​the buffer chamber. A first receiving bottle and a second receiving bottle are connected to the buffer chamber. The first receiving bottle is installed at the lower end of the buffer chamber, and the second receiving bottle is installed at the side end of the buffer chamber through a connecting pipe. A movable component is provided inside the buffer chamber. The movable component controls the opening and closing of the space above the first receiving bottle under the action of buoyancy. The aforementioned device only collects the initial urine fraction into the first receiving bottle, while the middle and final urine fractions are collected into the second receiving bottle. It cannot distinguish between the middle and final urine fractions, making it inconvenient to collect only the middle urine fraction for urine testing. Urine from different stages needs to enter the buffer chamber. When the initial urine fraction enters the first receiving bottle along the guide plate and movable baffle, some initial urine fraction still enters the second receiving bottle due to the impact force on the movable baffle, causing contamination of the middle and final urine fractions and resulting in low test accuracy. Furthermore, the second receiving bottle has no outlet, and it needs to be removed from the device before testing the middle and final urine fractions, which is complicated and inconvenient. Summary of the Invention

[0004] To improve the above situation, the present invention provides a disposable urine sample automatic segmentation collector that uses a leak-proof device to guide the urine sample to prevent urine leakage, and uses an automatic segmentation collection device to automatically segment the urine sample, making it convenient to collect the middle segment of urine.

Preferably, the height of the liquid guiding ring plate (16) gradually increases from one side to the other. The side of the collection support tube (6) has a front urine outlet (10). Preferably, the initial urine outlet (10) is located at the junction of the liquid guiding ring plate (16) and the inner wall of the collection support cylinder (6). Preferably, the urine outlet (10) and the leak-proof guide plate (1) are located on the same side of the collection support cylinder (6). One end of the front urine delivery tube (2) is connected to the front urine outlet (10) and is in communication with the front urine outlet (10). The other end of the urine delivery tube (2) is placed on the waste bag (3) and connected to the waste bag (3). The front urine outlet (10) is equipped with a miniature flow meter (11).

A signal converter, a data processor, and a controller are located on the side of the acquisition support cylinder (6). The miniature flow meter (11) is connected to the signal converter via a data cable. The miniature automatic telescopic pole (15) is connected to the controller via a data cable. The signal converter is connected to the data processor via a data transmission line, and the data processor is connected to the controller via a data transmission line. The signal converter can convert the electrical signal of the flow data collected by the micro flow meter (11) into a digital signal. The controller can be implemented using one or more application-specific integrated circuits (ASICs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components to execute instructions from a data processing device. The data processor and the signal converter interact with each other. The data processor stores a computer-readable storage medium, and when the computer-readable storage medium is executed, it performs the following steps: The digital signal of the flow data received from the micro flow meter (11) is processed, and the processed digital signal of the flow data is compared with a preset flow threshold. When the digital signal of the flow data is equal to the preset flow threshold, an execution command is sent to the controller. The controller controls the micro automatic telescopic rod (15) to retract downward. The micro automatic telescopic rod (15) drives the urine collection tube (7) to move downward. When the distance moved by the micro automatic telescopic rod (15) reaches the preset distance threshold, that is, when one end of the urine collection tube (7) is aligned with one end of the leak-proof liquid guide plate (1), the controller controls the micro automatic telescopic rod (15) to stop retracting.

The initial urine flows along the leak-proof guide plate (1) into the clearance groove (8), then from the clearance groove (8) into the collection support cylinder (6), flows onto the guide ring plate (16), and flows out from the initial urine outlet (10). It then flows through the initial urine infusion tube into the waste bag (3). The micro flow meter (11) collects the flow data of the initial urine and transmits the collected flow data to the signal converter. The signal converter converts the electrical signal of the flow data into a digital signal and transmits the digital signal of the flow data to the data processor. The data processor processes the received digital signal of the flow data and compares the processed digital signal of the flow data with the preset flow threshold. When the digital signal of the flow data equals the preset flow threshold, it sends an execution command to the controller. The controller controls the micro automatic telescopic rod ( 15) Retract downwards. The miniature automatic telescopic rod (15) drives the urine collection tube (7) to move downwards. When the distance moved by the miniature automatic telescopic rod (15) reaches the preset distance threshold, that is, when one end of the urine collection tube (7) is aligned with one end of the leak-proof guide plate (1), the controller controls the miniature automatic telescopic rod (15) to stop retracting. The mid-section urine enters the urine collection tube (7) along the leak-proof guide plate (1) and flows through the drainage tube (14) to the mid-section urine retention cup (5). The mid-section urine accumulates and rises in the mid-section urine retention cup (5). When the amount of mid-section urine exceeds the outlet (12) of the rear section urine, it is regarded as the rear section urine and flows out from the outlet (12) of the rear section urine. It flows through the rear section urine infusion tube to the waste bag (3). After the sampling is completed, when the urine sample is tested, the sealed outlet (13) is opened and the collected mid-section urine sample flows to the testing device for testing. Example 2

[0012] The difference between this embodiment and embodiment 1 is that: one end of the collection support cylinder (6) is provided with a grip handle (17), the grip handle (17) and the leak-proof liquid guide plate (1) are located on opposite sides of the collection support cylinder (6), and the other end of the grip handle (17) has an L-shaped structure; when in use, the patient can collect urine more stably by gripping the handle (17), reducing urine leakage and making the operation more convenient; Example 3

[0013] The difference between this embodiment and embodiment 1 is that: the urine collection tube (7) has a front urine guide channel (18) on its side, the front urine guide channel (18) corresponds to the clearance groove (8), there are multiple front urine guide channels (18), and the multiple front urine guide channels (18) are arranged equidistantly along the side of the urine collection tube (7); in use, the multiple front urine guide channels (18) can guide the front urine, so that the front urine can flow quickly along the multiple front urine guide channels (18) to the liquid guide ring plate (16); The leak-proof liquid guide plate (1) has a fan-shaped structure. The design of the width of the leak-proof liquid guide plate (1) gradually increases from one end to the other end, which can better prevent urine leakage and concentrate the urine at one end of the narrower leak-proof liquid guide plate (1), which helps the urine to flow quickly into the liquid guide ring plate (16) or the urine collection tube (7). The leak-proof liquid guiding plate (1) has an arc-shaped structure. The height of the leak-proof liquid guiding plate (1) gradually increases from the center to both sides, which allows urine to flow quickly along the center of the leak-proof liquid guiding plate (11) to the liquid guiding ring plate (16) or the urine collection tube (7). A sealing ring is placed between the other side of the liquid guiding ring plate (16) and the side of the urine collection cylinder (7), which can prevent the first part of the urine from entering the liquid guiding ring plate (16) from the relief groove (8) and entering the inner bottom surface of the collection support cylinder (6) through the gap between the other side of the liquid guiding ring plate (16) and the side of the urine collection cylinder (7), resulting in some of the first part of the urine not entering the waste liquid bag (3). The design of the other side of the liquid guiding ring plate (16) contacting the side of the urine collection tube (7) can limit the urine collection tube (7) when the micro automatic telescopic rod (15) moves the urine collection tube (7) downward, preventing the urine collection tube (7) from shaking during the movement. The design of the liquid guiding ring plate (16) with its height gradually increasing from one side to the other helps the first urine to quickly enter the first urine outlet (10) from the liquid guiding ring plate (16) and flow from the first urine delivery pipe (2) to the waste bag (3). When the miniature automatic telescopic rod (15) is not working, the design that the height of the upper end of the urine collection tube (7) is greater than the height of the upper end of the collection support tube (6) can prevent the first part of the urine from entering the urine collection tube (7). The first part of the urine can only flow into the collection support tube (6), enter the first part of the urine outlet (10) from the liquid guide ring plate (16), and flow to the waste liquid bag (3) through the first part of the urine delivery tube (2), thus realizing the automatic segmented collection of urine; The drainage tube (14) is a drainage tube. The other end of the drainage tube (14) is placed on the inner bottom surface of the collection support tube (6) and connected to the mid-section urine retention cup (5). This design allows the drainage tube (14) to extend and retract as the micro automatic telescopic rod (15) moves up and down, and at the same time allows the mid-to-late stage urine to enter the mid-section urine retention cup (5) from the urine collection tube (7). The system aims to prevent urine leakage by guiding the urine sample through a leak-proof device and to facilitate the collection of the middle segment of the urine sample by automatically segmenting the urine sample through an automatic segment collection device.
