Description
Technical Field
[0001] The invention belongs to the technical field of medical infusion, and in particular relates to an infusion monitoring device. Background Art
[0002] During medical infusion, medical staff usually need to monitor the infusion speed, infusion volume and abnormal conditions during the infusion process. In the prior art, medical staff mostly rely on manual observation or simple drop count monitoring devices to judge changes in infusion speed and infusion volume. However, this monitoring method has the following problems: on the one hand, manual observation often relies on the experience of medical staff and cannot provide timely warnings for sudden infusion abnormalities; on the other hand, drop count monitoring is easily affected by the patient or the external environment (such as patient movement, accidental pulling of the infusion tube or vibration in the environment, etc.), resulting in unstable monitoring results or large errors.
[0003] In addition, if the infusion bag is exposed to strong light or airflow during use, it may not only cause the temperature of the liquid in the bag to fluctuate or the drip rate to change, but also easily interfere with the measurement results of the weight sensor. For example, when the infusion bag is blown and swings, the data obtained by the weight sensor will fluctuate, making it difficult to stably reflect the actual remaining amount of liquid in the infusion bag. If the patient accidentally pulls the infusion tube during activities, it will directly involve the infusion bag or sensor through the infusion tube, further exacerbating the measurement error, which has not yet been effectively solved in existing infusion monitoring devices.
[0004] Based on this, how to design a device that can reduce the interference of environmental factors (such as wind, light, etc.) and patient misoperation (such as pulling the infusion tube) on the measurement, and can detect infusion abnormalities in real time through weight changes and issue warnings in time, has become an urgent problem to be solved in the current technical field. Summary of the invention
[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an infusion monitoring device, which can realize real-time detection of the weight of the infusion bag during the infusion process and promptly issue an alarm when the weight of the infusion bag changes suddenly, thereby providing medical staff with a more accurate and reliable monitoring method.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: An infusion monitoring device comprises a base, a back of the base is connected to a bracket, and a top of the bracket is connected to an isolation cabin; The isolation cabin is used to place the infusion bag; A weight sensor is connected to the top of the interior of the isolation cabin. During infusion, the infusion bag is hung on the weight sensor; A warning light for warning is connected to one end of the top of the isolation cabin; A heating plate is provided on the inner wall of the isolation cabin; A door is provided on one side of the isolation cabin, and an isolation plate is plugged into the door; One side of the bracket is connected with a supporting piece, and the supporting piece is used to place the drip bucket on the infusion tube; A first hook is provided at the bottom of the weight sensor, and the infusion bag is hung on the first hook. A connecting plate is connected to the top of the weight sensor, and the connecting plate is connected to the inner top of the isolation cabin by screws; The weight sensor includes a strain gauge arranged inside and a signal processing unit electrically connected to the strain gauge. The strain gauge is fixed on a metal elastomer and is used to convert the tiny deformation caused by the weight applied by the infusion bag into a corresponding analog electrical signal; the signal processing unit filters, amplifies and digitizes the analog electrical signal, and compares it with a preset weight threshold range in real time. When the comparison result shows that the weight change of the infusion bag exceeds or quickly deviates from the weight threshold range, the signal processing unit outputs an alarm signal to the warning light, thereby realizing timely reminder of abnormal situations during the infusion process.
[0007] The present invention further defines the technical solution: Furthermore, a fourth through hole is formed at the center of the bottom of the isolation cabin, and the infusion tube passes through the fourth through hole; A first placement groove is formed through the bottom of the isolation cabin, and the first placement groove is connected with the fourth through hole.
[0008] Furthermore, positioning members are arranged on both sides of the exterior of the hatch, and the cross section of the positioning members is arranged to be L-shaped; The isolation plate is inserted between the positioning pieces, an observation window is provided on the side of the isolation plate, and a blocking bar is fixedly connected to the outer side of the top of the isolation plate.
[0009] Furthermore, the bracket includes a receiving frame, the bottom of the receiving frame is provided with supporting legs, and the top of the receiving frame is fixedly connected with an elbow; One end of the elbow is fixedly connected with a connector; The top of the isolation cabin is symmetrically fixedly connected with threaded columns, which are connected to the connecting head through nuts.
[0010] Furthermore, a connecting seat is provided on the top of the isolation cabin, and a warning light is connected to the connecting seat.
[0011] Furthermore, first through holes are formed at equal intervals on the side of the receiving frame, a second hook is provided in the first through hole, a positioning head is provided on one side of the top of the second hook, and the positioning head is inserted into the first through hole.
[0012] Furthermore, a second through hole is formed through the side surface of the supporting leg; The supporting member is configured as a round tube with an opening at the top, and a second placement groove is formed through the side of the supporting member. A connecting arm is fixedly connected to the outer side of the supporting member, and a fixing plate is fixedly connected to one end of the connecting arm. The fixing plate is connected to the second through hole by bolts.
[0013] Furthermore, a third through hole is formed through one side of the bottom of the leg, a threaded groove is formed on one side of the base, and the leg is connected to the base by screws. When connected, the screws pass through the third through hole and are screwed into the threaded groove. Universal wheels are symmetrically arranged on the lower end surface of the base. Beneficial Effects
[0014] The present invention provides a nighttime visual infusion stand with residual liquid alarm. Compared with the prior art, it has the following beneficial effects: Traditional infusion monitoring mostly relies on manual observation or simple drop count, which makes it difficult to detect and alarm abnormalities during the infusion process in a timely manner; this infusion monitoring device sets a weight sensor in the isolation cabin and electrically connects it to the warning light. When the weight of the infusion bag deviates from the preset range, a signal is immediately sent out, allowing medical staff to identify potential problems at the first time.
[0015] When the existing infusion device is affected by the external environment light or airflow, it is easy to cause the infusion bag to shake and cause the weight detection data to fluctuate; the infusion monitoring device forms a relatively closed space by setting an isolation board in the isolation cabin, and sets a heating board on the inner wall of the isolation cabin, which can both block light and stabilize the internal temperature, reduce the interference of the external environment on the infusion process, and improve the accuracy of the detection result.
[0016] When the patient accidentally pulls the infusion tube, the infusion bag will be pulled through the drip bucket and interfere with the measurement of the weight sensor; the infusion monitoring device is provided with a support piece on one side of the bracket for placing the drip bucket. When the infusion tube is pulled by external force, the pulling force is borne by the support piece instead of directly acting on the weight sensor, thereby avoiding errors in the measurement data.
[0017] The base and the bracket are fixed with screws and universal wheels are set at the bottom to facilitate movement and position adjustment in medical facilities; the entire structure maintains high strength with the cooperation of the receiving frame, elbow and connector, and the isolation cabin is stably installed on the top of the bracket with the help of threaded columns, which can not only meet the installation requirements of infusion bags of different capacities but also ensure the accuracy of weight monitoring.

During the infusion process, the weight sensor 6 will sense the weight of the infusion bag in real time. When the weight change of the infusion bag suddenly changes, the weight sensor 6 will send an electrical signal to the warning light 4, causing the warning light 4 to issue a warning, thereby prompting the medical staff in time. The infusion bag is located in a relatively closed space formed by the isolation cabin 3 and the isolation board 5, which can not only shield the infusion bag from light, but also prevent the infusion bag from shaking due to wind, because when the infusion bag shakes, it will affect the measurement data of the weight sensor 6; The drip chamber is placed in the support member 7 to prevent the patient from accidentally pulling the infusion tube during the infusion process, thereby affecting the measurement data of the weight sensor 6; When the patient pulls the infusion tube, the pulling force will be transmitted to the support member 7 through the infusion tube and will not affect the measurement data of the weight sensor 6.
