Description

Technical Field

[0001] This utility model relates to the field of internal exudate detection technology, specifically an internal exudate abnormality alarm device. Background Technology

[0002] Most surgical patients, including those in hepatobiliary and pancreatic surgery, thoracic surgery, urology, gynecology, proctology, and orthopedics, have drainage tubes placed post-operatively. Internal medicine departments such as respiratory medicine, cardiology, and hepatology may also place drainage tubes depending on the progression of the disease. These tubes drain residual blood, fluid, chyle, bloody secretions, pancreatic juice, or intestinal secretions from the abdominal cavity, pleural cavity, pelvis, or surgical incision. Clinically, the number of drainage tubes varies, as do the volume and color of the drainage fluid. Inconsistent observation and judgment by different medical staff can lead to inconsistencies in medical records, making it difficult to accurately grasp the patient's condition. Depending on the location, composition, and duration of drainage, medical staff need to closely monitor the condition of each drainage tube and observe changes in the color, characteristics, and volume of the drainage fluid to detect disease progression and prevent complications.

[0003] Chinese invention patent CN111603622B discloses a portable drainage tube monitoring device, including a sleeve. The sleeve contains a first shaping part and a second shaping part, both extending along the length of the sleeve. A drainage groove is located between the first and second shaping parts. The sleeve has a first monitoring hole communicating with the drainage groove. A color sensor is installed above the first monitoring hole. The sleeve also has an alarm and a controller, both electrically connected to the controller. The color sensor detects the color of the drainage fluid in the drainage tube in real time. The controller compares the measured drainage fluid color with preset drainage fluid colors. If the measured drainage fluid color is not among the preset drainage fluid colors, the controller activates the alarm to sound an alarm indicating that the patient has been examined. This allows for 24-hour monitoring, with immediate alarms for any abnormalities, timely detection of the condition, and ensuring patient safety.

[0004] Chinese utility model patent CN219870997U discloses an intelligent device for identifying the color of drainage fluid, belonging to the category of medical devices. It includes: a housing with an internal cavity connected to an inlet and outlet; a color detection component including a clamp and a wire, one end of which is connected to the clamp, and the other end of which is located within the cavity; the clamp can move in and out of the inlet and outlet; the clamp is used to fix a drainage tube, and the clamp is equipped with multiple panchromatic light sensors and a multispectral light source, with each multispectral light source corresponding to one of the panchromatic light sensors. When the clamp is fixed to the drainage tube, the multispectral light source and the panchromatic light sensors are located on opposite sides of the drainage tube; and a controller located within the cavity, with both the multispectral light source and the panchromatic light sensors electrically connected to the controller. This device can detect the color of the drainage fluid in real time, providing medical personnel with an objective standard to assist doctors in making correct judgments and treatments.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model discloses an abnormal internal exudate alarm, including an upper connector 1 and a lower connector 2 for clamping a drainage tube. Both sides of the upper connector 1 and the lower connector 2 are provided with elastic extension components, which include a lateral extension mechanism and a longitudinal extension structure. An upper and lower connecting component is provided between the two longitudinal extension structures. An integrated detection component is provided inside the upper connector 1, which is used to detect the color and flow rate of the liquid in the drainage tube.

[0026] Specifically, the lateral extension mechanism includes a lateral extension member 3 and a lateral extension connecting component, the lateral extension connecting component being used to connect the lateral extension member to the upper connecting member 1; the longitudinal extension structure includes a longitudinal extension member 4 and a longitudinal extension connecting component, the longitudinal extension connecting component being used to connect the longitudinal extension member 4 to the lateral extension member 3; an upper and lower connecting component is provided between the longitudinal extension member 4 connected to the upper connecting member 1 and the longitudinal extension member 4 connected to the lower connecting member 2; a flexible cotton for flexible connection with the drainage tube is fixedly connected to the surface of the lateral extension member 3.

[0027] In this embodiment, the gap between the upper connector 1 and the lower connector 2 can be adjusted by using the horizontal and vertical extension connecting components, thereby accommodating drainage tubes of different diameters. Then, the upper and lower connecting components are connected to achieve quick installation and disassembly, making it easy to reuse.

[0028] Specifically, the integrated detection component includes a mounting housing 5, a color sensor 6, a flow rate detector 7, a photoelectric sensor 8, and an alarm 9. The surface of the upper connector 1 has a mounting groove 10 that penetrates the upper connector 1. The mounting housing 5 is movably connected to the inner wall of the mounting groove 10. The color sensor 6, flow rate detector 7, photoelectric sensor 8, and alarm 9 are all installed inside the mounting housing 5 using connecting screws. Inside the mounting housing 5 is a ribbon cable connector 11, into which the leads of the color sensor 6, flow rate detector 7, photoelectric sensor 8, and alarm 9 are plugged. The surface of the upper connector 1 also has a battery slot 12 and a circuit board slot 13. A circuit board 14 is installed inside the circuit board slot 13, and the ribbon cable connector 11 is plugged into the lead socket on the circuit board 14.

[0029] In this embodiment, the mounting housing 5 is placed inside the mounting slot 10. The color sensor 6, flow rate detector 7, photoelectric sensor 8, and alarm 9 are all mounted on the mounting housing 5. A ribbon cable connector 11, similar to a plug structure, is integrated inside the mounting housing 5 to gather the leads of the color sensor 6, flow rate detector 7, photoelectric sensor 8, and alarm 9 into a single socket. When placing the mounting housing 5, the ribbon cable connector 11 is plugged into the lead socket integrated on the circuit board 14, enabling quick installation. This also facilitates easy disassembly and replacement of the sensors when needed.

[0030] Specifically, a cover plate 15 is provided on the top of the mounting shell 5. The mounting shell 5 is fixedly connected to the mounting groove 10 by fixing screws. A transparent plate 16 is connected to the inner side wall of the mounting groove 10. The transparent plate 16 is located at the bottom of the mounting shell 5.

[0031] In this embodiment, the cover plate 15 is used to encapsulate the mounting shell 5. The transparent plate 16 allows the signals emitted by the color sensor 6, flow rate detector 7, and photoelectric sensor 8 to be projected onto the drainage tube, facilitating detection. Additionally, the transparent plate 16 may have a notch, allowing the flow rate detector 7 to extend to the outside and directly contact the drainage tube, thus facilitating flow rate detection using the pressure difference method.

[0032] Specifically, the lateral extension connecting component includes a first T-shaped rod 17, which is fixedly connected to the lateral extension member 3. An insertion groove 18 is provided on the surface of the upper connecting member 1. The surface of the first T-shaped rod 17 is movably connected to the inner wall of the insertion groove 18. A connecting plate 19 is movably sleeved on the surface of the first T-shaped rod 17. The connecting plate 19 is inserted into the upper connecting member 1 through a plug post. A first connecting spring 20 is sleeved on the surface of the first T-shaped rod 17. One end of the first connecting spring 20 is connected to the connecting plate 19.

[0033] In this embodiment, pulling the lateral extension 3 can move the first T-shaped rod 17, compressing the first connecting spring 20. The retraction force of the first connecting spring 20 can provide clamping force, adapting to the diameter of the drainage tube while also increasing friction to prevent detachment. The connecting plate 19 allows for disassembly, and the connecting post is inserted into the connecting piece through an interference fit.

[0034] Specifically, the longitudinal extension connecting component includes a second T-shaped rod 21, which movably passes through the transverse extension 3 and is fixedly connected to the longitudinal extension 4. A second connecting spring 22 is sleeved on the surface of the second T-shaped rod 21, and one end of the second connecting spring 22 is connected to the longitudinal extension 4.

[0035] In this embodiment, the second T-shaped rod 21 and the second connecting spring 22 can realize the vertical extension of the longitudinal extension 4 to adapt to the diameter of the drainage tube.

[0036] Specifically, the upper and lower connecting components include a fixed locking block 23 and a movable hook plate 24. The fixed locking block 23 is fixedly connected to the longitudinal extension 4 connected to the upper connecting component 1, and the movable hook plate 24 is movably connected to the longitudinal extension 4 connected to the lower connecting component 2. The movable hook plate 24 is movably connected to the guide rod 25, and the guide rod 25 is fixedly connected to the longitudinal extension 4 through a connecting block. A third connecting spring 26 is sleeved on the surface of the guide rod 25, and both ends of the third connecting spring 26 are connected to the movable hook plate 24.

[0037] In this embodiment, during installation, the movable hook plates 24 are pressed, causing the two movable hook plates 24 to move towards each other. When the movable hook plates 24 correspond to the fixed block 23, under the reset action of the third connecting spring 26, the movable hook plates 24 are connected to the fixed block 23, thereby achieving the connection and fixation of the upper and lower longitudinal extensions 4.

[0038] The working principle and usage process of this utility model are as follows: When in use, the upper connector 1 and the lower connector 2 are placed opposite each other on both sides of the drainage tube. The diameter of the drainage tube is adapted by adjusting the transverse extension 3 and the longitudinal extension 4. Flexible cotton is fixedly connected to the transverse extension 3, which can contact the drainage tube to increase friction and protect the drainage tube.

[0039] Color sensor 6, flow rate detector 7, and photoelectric sensor 8 detect the liquid in the drainage tube. Photoelectric sensor 8 uses a reflective structure, judging the flow state by changes in the intensity of light reflected from the liquid surface, thus determining whether liquid is flowing through the drainage tube. When liquid flow is detected, a timer on circuit board 14 starts counting and stops when no more liquid flows. Simultaneously, combined with color sensor 6, it can determine whether abnormally colored liquid is flowing and the duration of such flow. If bright red or dark red liquid is detected flowing for more than 30 seconds, alarm 9 will sound. Normal outflowing liquid is pale yellow, pale red, or a small amount of bright / dark red. Based on the duration of continuous flow, the flow rate detected by the flow sensor, and the diameter of the drainage tube, the hourly volume of abnormally colored liquid can be calculated. If the drainage fluid is bright red / dark red and the volume exceeds 100 m³ / h, it indicates possible active bleeding in the abdominal cavity, and alarm 9 will sound.
