Description
Technical Field
The utility model relates to an artificial intelligence technical field especially relates to the device that reports to the police and reminds relevant personnel after the infusion or hanging water are accomplished, concretely relates to alarm device that finishes infusing.
Background
Infusion, also known as drip infusion or drip infusion, is a large dose (more than 100ml per administration) of injection infused into the body by intravenous drip. Are usually packaged in glass or plastic infusion bottles or bags and contain no preservatives or bacteriostatic agents. When in use, the dropping speed is adjusted by the infusion apparatus, and the infusion apparatus continuously and stably enters the vein to supplement body fluid, electrolyte or provide nutrient substances.
When the existing transfusion is finished, people need to check and ensure whether the liquid medicine in a drip tank (a transfusion bottle or a transfusion bag) is completely conveyed, and when the liquid medicine in the drip tank is completely conveyed, the drip tank needs to be replaced in time or the transfusion is stopped, so that the blood of a human body is prevented from flowing back to a transfusion device. The residual liquid medicine in the drip tank is checked by people, so that the patient or an attendant generates worry, wastes time and energy, and is easy to be neglected to influence the transfusion treatment. Therefore, it is necessary to monitor the residual liquid medicine in the drip tank by technical means and alarm when the liquid medicine in the drip tank is completely infused.
The Chinese patent invention CN105536103A discloses an induction drip alarm, which comprises a tube body, wherein a spring is arranged at the top end in the tube body, the lower end of the spring is detachably connected with an infusion bottle, and the infusion bottle moves in the vertical direction along with the extension and retraction of the spring; the infusion bottle alarm is characterized in that an infrared sensing device is arranged on the outer side of the tube body and senses an infusion bottle in the tube body, the infrared sensing device is connected with a controller through a line, the input end of the controller is connected with a power supply, the output end of the controller is connected with an alarm, and the alarm is connected with the power supply to form a loop. After the liquid medicine in the infusion bottle is conveyed, the weight of the infusion bottle is reduced, the tension of the spring is reduced, the spring contracts to drive the infusion to be close to the infrared sensing device, the infrared sensing device senses the infusion bottle in the tube body, the infrared sensing device generates sensing signals, the controller is triggered to be conducted through the sensing signals, and the current of the power supply is communicated to the alarm through the controller to give an alarm.
Although the induction drip alarm can roughly detect that the liquid medicine in an infusion bottle is reduced, after the induction drip alarm is used for a long time, the elastic coefficient K of the spring is increased, the length change of the spring is larger under the condition of the same tension, the alarm time is inaccurate, and the weight of an infusion container is not uniform, so that the alarm precision is influenced. In addition, at present, the infusion bag gradually replaces an infusion bottle and becomes a main container for containing liquid medicine, and the induction drip alarm cannot be suitable for the infusion bag and is narrow in application range.
Chinese patent CN102631724A discloses a drip infusion monitoring alarm, which comprises a control box and a drip tank sensor connected with the control box through a flexible lead. The drip cup sensor is made of C-shaped elastic material, and a pair of ultrathin infrared transmitting and receiving diodes are embedded in the drip cup sensor; an electronic circuit board is arranged in the control box, and a microcomputer chip and electronic components for detecting and identifying infrared signals, a toggle switch for switching on or off a power supply, an LED lamp for indication and an alarm buzzer are arranged on the electronic circuit board. When no liquid medicine drips in the drip cup (namely the Murphy dropper) for more than two to three seconds, the control box drives the buzzer to give out an alarm of 'tic, tic and …'; when the alarm is given, if the liquid medicine drips in the drip tank, the alarm is stopped automatically and the monitoring is resumed.
Although the drip infusion monitoring alarm can be suitable for various infusion containers and is not influenced by the weight of the infusion containers, the infrared emission and control box continuously consumes electric energy, the electric energy consumption is large, the continuous work can be realized only by an external power supply, the control box is required to be independently equipped, the occupied space is large, the carrying is inconvenient, an electronic circuit board, a sensor and the like are required to be equipped, the cost is high, and the large-area popularization is difficult.
Therefore, it is urgently needed by those skilled in the art to develop an infusion completion alarm device with simple structure and low cost, which can accurately alarm after the liquid medicine in the infusion container is completely infused, so as to remind the medical staff to replace the medicine bottle, thereby reducing the burden of the medical staff and the family members of the patient.
