New description: [New technical field] This creation is related to a drip level detecting device, especially a device that detects and outputs a signal warning when the liquid in the drip bottle is about to be used up. [Prior Art] • When the human body must supplement the medicine or nutrient, the common medical behavior is supplemented to the human body by intravenous injection in a drip manner. However, the time of supplementing the medicine or nutrient in the drip bottle _ is usually long. The person will go to the observation when the estimated time arrives. If the medicine or nutrient in the drip bottle is about to be used up, the new drip bottle will be replaced. However, it has been found clinically that caregivers have forgotten to replace because they are too busy or expect an incorrect time estimate, causing the air in the drip bottle to be injected into the body, causing medical negligence. In view of this, a warning device for medical drip is disclosed in the prior art to improve this problem. Lu Wei's reference to Fig. 8 is a medical device disclosed in the above prior art. The warning device is combined with the appropriate position of the drip bottle 9. In the warning device, δ has an infrared light source device. The driving circuit 9 is composed of a light source detecting circuit 9 1 which is mounted on one side of the drip bottle 9 and the detecting circuit 9 1 is mounted on the opposite side of the drip bottle 9 When the water level in the drip bottle 9 is high or lower than the warning device, the detecting circuit 9 1 detects the intensity of the light source wavelength of the driving circuit 9 ,, and turns the signal warning 'to immediately replenish the medicine or nutrient in the drip bottle 9 . 3 M394139 The warning device for medical drip disclosed in the prior art mainly detects the liquid level in the drip bottle 9 by the infrared light source device. The main problem is that the drip bottle 9 is filled with a liquid such as a medicament or a nutrient. Turbidity affects the penetration of infrared rays, and its sensitivity is easy to be detected and reduced, resulting in misjudgment; and the conventional warning device uses expensive infrared light source devices, such as each bottle of drip bottle 9 needs to be installed. , it must cost a considerable amount of equipment, which is the focus of this creative work. [New content] One of the purposes of this creation is to solve the above problems and provide a drip level detecting device that can accurately detect and issue a signal warning when the liquid in the drip bottle is about to be used up, and the warning device Immediately notify the person to replace the drip bottle to prevent the air from being injected into the human body due to the use of the liquid in the drip bottle, so that the drip injection is safer. The second purpose of this creation is to use the temperature sensor on the drip bottle to sense the device, which can effectively save the cost of the device for detecting the liquid volume in the drip bottle. For the purpose of the foregoing, the present invention is provided with at least one temperature sensor for detecting the temperature difference in the drip bottle on the side wall of the drip bottle, and is electrically connected to the temperature sensor by at least one alarm, when the drip bottle is inside When the liquid changes due to the use of the liquid, the temperature difference between the liquid and the air causes the temperature sensor to change the resistance value to output a signal and activate the at least one alarm. The above and other objects and advantages of the present invention will become more apparent from the detailed description and the accompanying drawings. The difference, but the choice of the actual _, then: line j has a description, and its construction is shown in the drawing. Stomach, to be evaluated [Embodiment] The person selected for this creation is not selected for patent application. Please refer to Figure 1 to Figure 5 for the structure of the embodiment. Structural limitations. / This creation system - a drip level fine channel, which in the preferred embodiment does not have a drop bottle 第 as shown in Figure 1, where the drop bottle 1 contains a liquid such as a medicament or a nutrient 2 Injecting into the human body by intravenous injection: 'This drip bottle 1 is provided on the bottle close to the bottle σ! 温度-temperature sensor 3' This temperature sensor 3 is electrically connected to at least the "alarm 4". The temperature sensor 3 of the present embodiment is a platinum temperature sensor (ρτ_100) 'which is in the form of a sheet and is relatively thin' for adhering to the drip bottle 1, and the temperature sensor 3 is When the temperature sensor 3 wants to change the position, the temperature sensor 3 can be peeled off and pasted in the position of worrying, thereby achieving the effect of re-adhesive adhesion. As shown in the circuit diagram of FIG. 2, the front end of the temperature sensor 3 of the present embodiment is a power supply area 5, and at the rear end of the temperature sensor 3 is an amplifier 6, via which the temperature sensor 3 is connected. The power supply is supplied, and when the temperature sensor 3 senses the temperature difference, the resistance value changes, and the output voltage changes, and the output voltage changes as a signal, and the amplification signal is amplified by the amplification 5 M394139 6 and Output to the at least one melody 4 as shown in FIG. 3 'The alarm 4 of the present embodiment includes - a light-emitting element 40 and a sound-emitting element 4!, the light-emitting device is an -LED lamp in this embodiment, In addition, the sounding element 4α is a buzzer in this embodiment, thereby serving as a signal wheel (4) for sensing temperature ϋ3, and simultaneously emitting a sound by the light-emitting element 40 and the sounding element 4 to achieve an alarm effect. In addition, the foregoing warning device has the light-emitting element 4 ◦ and the sound-emitting element 4 1 simultaneously present as a warning, but the warning device 4 can also be simplified, only having the light-emitting element 40 to emit light as a warning, or only having the sound-emitting element 4 The sound is emitted as a warning, and the same can achieve the effect of warning. In the embodiment, the warning device 4 is disposed at the remote end, and is disposed at the nursing station. The temperature sensor 3 transmits the signal to the warning device 4 of the nursing station by using a wired or wireless transmission module, even if the care is performed. The person can not immediately observe the state of use of the drip bottle 1 in the ward, and it is still possible to know whether the drip bottle 1 has to be replaced by the sound of the bes 4 shown in the nursing station and the flashing of the light. The temperature sensor 3 of this creation generates a signal by a change in temperature difference. As shown in FIG. 4, the temperature sensor 3 attached to the drip bottle 1 is still located under the liquid level 2 1 of the liquid 2, and the section sensed by the temperature sensor 3 as a whole is still in the liquid 2, so The temperature difference is extremely small, and the temperature sensor 3 does not output a signal to the warning device 4 in this state; as shown in Fig. 5, when the liquid level of the liquid 2 in the drip bottle 1 starts to be lower than the temperature sensor 3 M394139, by the temperature difference between the liquid 2 and the air in the drip bottle 1, the temperature sensor 3 generates a resistance value change 'to turn out the signal and activate the at least one warning device 4' You can go to the replacement of the new drip bottle by knowing the warning. In addition, if the device is in a place where the temperature difference is obvious, two sets of temperature sensors 3 can be set in the drip bottle 1 to increase the stability. The group temperature sensor 3 causes two sets of temperature senses due to the change of the liquid level 2 1 . The detector 3 detects different output voltage changes as signals, and amplifies the signal through the amplifier 6 and outputs the signal to the at least one alarm 4 . When it is implemented, it mainly adheres to the side wall of the drip bottle 1 to detect the change position of the liquid surface. As shown in Fig. 6, the temperature sensors 3 attached to the top and bottom of the drip bottle 1 are located under the liquid 2, and the sections sensed by the two sets of temperature sensors 3 are all located in the liquid 2, The same temperature is measured and the output voltage is also the same, so there is no voltage difference between the two temperature sensors and there is no output signal to the warning device ♦ 4. Further, as shown in FIG. 7, when the liquid level 2 i of the liquid 2 in the drip bottle is lower than the upper temperature sensor 3, the air in the drip bottle 1 is detected by the upper temperature sensor 3. The difference between the temperature and the temperature sensor 3 detected by the lower temperature sensor 3 causes the two sets of temperature sensors 3 to generate different voltage output values, and the voltage difference value detected by the two temperature sensors 3 is the output signal. The at least one alerter 4 is activated, and the caregiver can go to the replacement of the new drip bottle 1 by knowing the warning. 7 M394139 It is not difficult to find out from the above description that the advantage of this creation is that the device can achieve liquid level detection by using a set of temperature sensors 3 in an environment with little difference in room temperature; The same stability can be achieved by using two sets of temperature sensors 3 in a severe environment. The temperature sensor 3 detects the liquid level by the temperature difference between the liquid 2 and the air in the drip bottle 1. Since the detection of the temperature sensor 3 does not optically penetrate the liquid 2, regardless of the drip bottle 1 The liquid turbidity of the liquid 2 is high or low, and does not affect the sensitivity of the temperature sensor 3, so that the liquid level of the drip bottle 1 can be accurately detected, and the nurse is informed of the new bottle through the warning device 4 The replacement is to prevent the air from being injected into the human body due to the use of the liquid 2 in the drip bottle 1, thereby ensuring the safety of the medicament or nutrient in the human body. Moreover, since the price of the temperature sensor 3 is lower than that of the conventional infrared light source device, the temperature sensor 3 is installed as a liquid level sensor on each of the drip bottles 1 to save considerable device cost. . The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, so any change in the numerical value or substitution of equivalent elements should still be the subject of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives, and it has been in compliance with the provisions of the Patent Law and has filed a patent application.
