In
Then, the alarm module 10 includes a visual alarm unit 100 and an audible alarm unit 102, in which the visual alarm unit 100 is a light emission element such as a LED or a lamp to make the light warning, and the audible alarm unit 102 is a sound device such as a buzzer to make the audible warning. In addition, the alarm module 10 has a primary warning mode and an emergency warning mode. When the alarm module 10 is in the primary warning mode, the alarm module 10 will executes the visual alarm unit 100 and the audible alarm unit 102 every minute in a time interval, so that the alarm module 10 has one time warning every minute in the time interval. When the alarm module 10 is in the emergency warning mode, the alarm module 10 will starts the visual alarm unit 100 and the audible alarm unit 102 sustained in the time interval, so that the alarm module 10 has warns continuously in the time interval to attain a more strongly warning for the user.
The setting interface 12 is an operation platform for operating the warning device 1 which includes an adjustment modify unit 120 and a display unit 122. The user can set a total dosage value by using the adjustment modify unit 120 according to the dosage how much the user want to inject, and the total dosage value can be showed on the display unit 122 for the user. The display unit 122 may be a display panel, and the adjustment modify unit 120 may has an increase key button and a decrease key button for adjusting the total dosage value.
The measurement module may be an electronic scale, and further includes or connects to a hanging tool to hang the drip bottle 3 (as shown in the
In other words, when the drip bottle 3 includes the drug therein on the hanging tool, the measurement module 14 will generate an origin voltage according to the weight of the drip bottle 3 which includes the drug therein. The measurement module 14 continuously monitors the voltage changed by changing the weight of the drip bottle 3 includes drug therein. With the dosage slowly drips into the patient's vein, the weight of the drip bottle 3 includes the dosage will be reduced. Thus, the measurement module 14 detects the voltage value which different from the original voltage value so as to a current voltage value is to be generated. It should be illustrated that in one infusion procedure, the initial voltage is defined as a constant value as the start of the infusion. Because there are many detection processes during the infusion process depended on the measuring frequency to generate a plurality of current voltage values.
The control module 16 electrically connects to the alarm module 10, the setting interface 12 and the measurement module 14 respectively. The control module 16 loads the total dosage value from the setting interface 12, and receives the original voltage value and the current voltage value from the measurement module 14 and according to the total dosage value, the original voltage value and the current voltage value that measured in accordance with measurement rules to execute the control module 10 for warning alert actions
Refer to
For example, if the weight of 1 milliliter (ml) of the drug is 1 gram (g), the total weight of 200 ml dosage and drip bottle 3 with the dosage therein is 500 g and before the infusion treatment beginning, the measurement module 14 can detects an original voltage of the drip bottle 3 with the dosage therein which is denoted as the original voltage. The original voltage is transmitted to the control module 16 to calculate the original weight of the drip bottle 3 with the dosage therein is 500 g, which is the sum of the weight of the dosage and the drip bottle 3. Then, the ratio of the voltage and weight of the drip bottle 3 with the dosage therein is to be calculated in step S52, if the dosage of the infusion is 200 ml, the user can set the total dosage value is 200 ml through the setting interface 12 and the control module 16 can load the total dosage value is 200 ml from the setting interface 12.
Then, in a measurement frequency, when the infusion dosage is dipped out off the drip bottle 3 is 10 ml, the measurement module 14 will measure the voltage according to the reduction of 10 ml of the drip bottle 3 containing the dosage therein, and the voltage is the current voltage. At this time, the control module 16 compares the current voltage value with the original voltage in accordance with the step S54 to calculate the voltage difference and the weight difference is 10 g in accordance with the step S55. That is to say, the infusion of dosage is 10 ml. Thus, the residual dosage is 190 ml in the drip bottle 3 according to the step S56, and the residual dosage (190 ml) is larger than the first warning value such that the control module 16 did not execute the alarm module 10 to alarm.
How ever, with more and more of the dosage is dripped out off the drip bottle 3, the residual dosage within the drip bottle 3 is also fewer and fewer. When the residual dosage is lower than the first warning value, the control module 16 will executes the alarm module 10 to be the primary warning mode according to the step S57 to alarm the dosage is to be exhausted and to be replaced or supplement for the user. If the dosage is still dripped out off the drip bottle 3 and the user does not replace a new drip bottle 3 or supplement more dosage into the drip bottle 3, to let the residual dosage is lower than the second warning value such as 5 ml, the control module 16 transforms the alarm module 10 to an emergency warning mode from the primary warning mode to remind the dosage within the drip bottle 3 is to be run out for the user, whereby, by two-stages warning mechanism not only reduces the work loading and burden for the staff and improves the medical service quality of medical facilities can be improved by adding the alarm frequency.
Furthermore, the user may add the additional drug into the drip bottle 3 during the infusion process. At this time, the user can adjust the dosage within the drip bottle 3 by the adjustment modify unit 120 of the setting interface 12 after additional drug is added into the drip bottle 3. The added dosage is added to the total dosage value within the drip bottle 3. For example, if the additional drug is 50 ml, the total dosage value within the drip bottle 3 is adjusted to 250 ml according to above measurement rule. That is to say, the original dosage is 200 ml that is to be changed as the 250 ml, in this way, the additional dosage of the drug will not affect the original timing for warning, to achieve higher compatibility and higher maneuverability.
According to the above embodiments, the warning device 1 containing infusion apparatus further includes a power supply module 18. The power supply module 18 is the power supply for the warning device 1, and electrically connects to the control module 16. The control module 16 compares the surplus power supply value and a power warning value, when the surplus power supply value is lower than the power warning value, the control module 16 will instruct the alarm module 10 to alarm a lower battery message.
Certainly, the surplus power supply value can also display on the display unit 122 of the setting interface 12. Thus, the surplus power supply value of the power supply module can show for the user clearly and convenience for charging. Otherwise, the above alarm message can also show on the display unit 122 of the setting interface 12, and the residual dosage is calculated according to the step S56 within the drip bottle 3 can also be displayed on the display unit 122 of the setting interface 12 to show the residual dosage more clearly for the user.
Accordingly, the warning device can set the desired infusion dosage through the setting interface, the weight of the drip bottle is measured continuously by the measurement module, the residual dosage within the drip bottle is calculated according to the measurement rule of the control module and the control module executes the alarming when the residual dosage within the drip bottle is lower than the emergency warning value such that the work loading and burden for the staff and the quality of medical care of the medical facility can be improved.
