Description
Technical Field
[0001] The present application relates to the technical field of medical device production, and in particular to a system for detecting drainage fluid effusion in vivo. Background Art
[0002] Fluid accumulation in the body usually refers to excessive accumulation of fluid in body cavities (such as the thoracic cavity, abdominal cavity, pericardial cavity, etc.) beyond the normal range. This effusion may be caused by a variety of reasons, including inflammation, tumors, bleeding, trauma, obstruction or urinary tract and bile duct leakage. The presence of effusion not only compresses the surrounding tissues and affects organ function, but may also become a "hotbed" for the further development of the disease. In terms of detecting fluid accumulation in the body, the medical community has developed a series of sensitive and reliable diagnostic methods. Extracting effusion for cytological, biochemical, bacteriological and other examinations helps to clarify the nature and cause of the effusion; for example, the captured effusion image is compared with a standard sample paper, which contains effusion images of different properties, quantities and characteristics, as well as corresponding diagnostic information. The comparison process can be achieved through image processing algorithms or manual observation. According to the comparison results, the nature of the effusion (such as transudate, exudate) and other related characteristics (such as color, transparency, etc.) are judged. This information has important reference value for the diagnosis and treatment of the disease.
[0003] At present, the sampling and testing process of effusion generally relies on manual operation. This traditional method is not only inefficient, but also requires the intervention of nurses for each test, which undoubtedly increases the consumption of medical resources and labor costs. In view of this situation, the market urgently needs an innovative instrument that can be operated independently by patients and realize fully automatic sampling and testing. In addition, it is also necessary to pay attention to its detection accuracy to ensure that each sampling and test can achieve medical-level accuracy, thereby providing patients with a reliable basis for diagnosis. Summary of the invention
[0004] The present device provides a system for detecting drainage fluid effusion in vivo, and the specific implementation methods are as follows:
[0005] A system for detecting drainage fluid effusion in vivo, comprising:
[0006] The sampling belt and the comparison belt are arranged in parallel, and the two ends of the two belts are respectively wound on the unwinding roller and the winding roller, and the sampling belt corresponds to the liquid inlet vertically. A number of sampling sheets are equidistantly arranged on the sampling belt. The sampling belt and the comparison belt are driven forward by the winding roller to realize the automatic switching of the sampling sheets during each sampling test;
[0007] The route of the sample piece is divided into the first isolation chamber, the sampling chamber, the detection chamber and the second isolation chamber, which are independent of each other. A camera is provided on the top of the detection chamber, which is used to scan and compare the color difference between the sample piece and the comparison tape.
[0008] A controller is provided with a solenoid valve on the liquid inlet, a winding roller is connected to a driving assembly, and a photoelectric locator for detecting when the sampling piece reaches the sampling position is provided at the bottom of the sampling belt; the signal input end of the controller is electrically connected to the photoelectric locator, and its signal output end is electrically connected to the driving assembly, the solenoid valve and the camera respectively.
[0009] Based on the above technical scheme, by setting the precision sampling belt and the comparison belt on the unwinding roller and the winding roller, it is successfully achieved that the sampling piece can be automatically and efficiently switched during each sampling and detection process, which not only greatly improves the convenience and efficiency of operation, but also ensures the continuity and accuracy of sampling; at the same time, the controller and high-definition camera technology are also integrated to make real-time comparison and detection of samples possible. The comparison and detection principles of the camera are all existing conventional technical means; the photoelectronic positioner and solenoid valve can also automatically select the time for the effusion to fall. The light source inside the positioner emits one or more light signals, which are transmitted to the top of the sampling belt through optical elements. When the light signal encounters the sampling piece, part of the light will be reflected or scattered back, and the light receiver in the positioner receives and determines that the sampling piece has reached directly below the liquid inlet.
[0010] Preferably, it also includes a box body for accommodating the first isolation chamber, the sampling chamber, the detection chamber and the second isolation chamber, the top of the box body is provided with a sampling hopper, and the bottom of the sampling hopper is provided with a liquid inlet connected to the sampling chamber.
[0011] Different from the above technical solutions, a hoisting sampling bag can be directly used to replace the sampling bucket, and the solenoid valve can be installed at the bottom of the sampling bag; a weighing module can be installed between the top of the sampling bag and the hoisting part; or a second camera can be installed on the side of the sampling bag to determine the weight of the liquid in the sampling bag by reading the scale of the sampling bag.
[0012] Preferably, it also includes a purge assembly arranged at the end of the sampling chamber, which is composed of a fan and a vertical air duct. The fan acts on the sampling piece after sampling to remove unabsorbed accumulated liquid.
[0013] Based on the above technical solution, a purge component is added to the conveying path of the sampling belt to achieve accurate cleaning of the residual accumulated liquid on the sampling belt. Taking into account the problem of accumulated liquid that may not be completely absorbed by the sampling piece during the sampling process, the accumulated liquid can be promptly and effectively cleared through the precise operation of the purge component. This also effectively prevents the accumulated liquid from entering the detection chamber, thereby avoiding potential contamination of the camera. As the core component of the detection system, the clarity and stability of the camera are crucial. Once contaminated, it will not only affect the accuracy of the test results, but may also cause damage to the camera itself.
[0014] Preferably, a waste discharge box is provided at the bottom of the sampling chamber for laterally sliding movement, and a liquid accumulation groove opening upward is provided in the waste discharge box at a position corresponding to the liquid inlet; an inclined slope groove opening upward is provided in the waste discharge box at a position vertically corresponding to the purge assembly, an exhaust grille is provided at the upper part of the inclined slope groove, and its lower part is connected to the liquid accumulation groove.
[0015] Based on the above technical solution, by configuring a waste discharge box, the excess liquid scattered from the liquid inlet is collected in a centralized manner, while the liquid removed by the purge component is also properly received, thereby greatly avoiding the risk of disorderly diffusion or overflow of the liquid.
[0016] Preferably, the comparison tape is provided with a plurality of color cards equidistantly along its length direction, and the color cards correspond to the sampling sheets one by one.
[0017] Preferably, the sampling belt is provided with hollow grooves along its length direction and between adjacent sampling pieces for the accumulated liquid to fall.
[0018] Based on the above technical solution, a series of hollow grooves are opened at uniform intervals on the sampling belt to effectively discharge the excess liquid in the front and rear sections during the sampling process. When the hollow grooves on the sampling belt move to the position corresponding to the liquid inlet, the liquid that is not absorbed by the sampling piece can be guided and discharged, thereby avoiding the accumulation and interference of the liquid, and also realizing the sampling of only the liquid in the middle section.
[0019] Preferably, a third isolation compartment for installing a driving assembly is provided at the back of the box body, the unwinding roller and the winding roller are both axially split structures, the axial splits of the winding roller are connected to different driving sources, a coil spring structure is provided between the axial splits of the unwinding roller, the unwinding roller is composed of a first rotating roller rotatably connected to each other and used for winding a sampling tape and a second rotating roller for winding a comparison tape, and the winding roller is composed of a third rotating roller rotatably connected to each other and used for winding a sampling tape and a fourth rotating roller for winding a comparison tape;
[0020] The driving assembly includes a driving sprocket and a driven gear arranged coaxially, the two are slidably connected, the driving sprocket is connected to the fourth rotating roller, and the driving sprocket is also connected to the driven sprocket through a chain, the driven sprocket is connected to the second rotating roller, and the driving sprocket is connected to the output end of the second motor;
[0021] The driven gear is meshed with the driving gear, and the driving gear is connected to the output end of the first motor; a cavity is arranged in the second rotating roller, an extended inner roller is arranged axially in the cavity of the first rotating roller, and interacting raised paddles are equidistantly arranged on the outer circumference of the extended inner roller and the inner circumference of the cavity.
[0022] Preferably, the driven sprocket, the driving sprocket, the driven gear and the driving gear are all rotatably mounted in the third isolation chamber via a mounting frame.
[0023] Based on the above technical scheme, by setting a coaxially arranged driving sprocket and driven gear, the second motor and the first motor can be used to realize normal synchronous feeding and detection of the sampling belt and the comparison belt, and at the same time, the sampling belt can be displaced relative to the comparison belt to realize comparison inspection of different sampling pieces with the same color cards, thereby further improving the accuracy of detection; similarly, according to the exchange of the layout position and the adjustment of the sampling bucket position, the comparison belt can also be displaced relative to the sampling belt, that is, a single sampling piece corresponds to two colorimetric pieces for detection.
[0024] In summary, this application includes the following beneficial technical effects:
[0025] 1. The present invention realizes automatic switching of the sampling strips each time sampling and testing by arranging the sampling strips and the comparison strips on the unwinding roller and the winding roller, and realizes real-time automatic comparison and testing of the samples by using the controller and the camera;
