Please refer to FIG. 2, which is a second block diagram of the medical fluid transport device of the present invention. In the figure, the medical fluid transmission monitoring device 10 includes a portable control body 11 and a detachable liquid chemical driving body 12. The portable control unit 11 has a receiving space 111 and a control unit 112. The control unit 112 controls the flow of the liquid medicine. The control unit 112 has a control signal 1121, a pump type detecting unit 1122 and a plurality of liquid chemicals. Transfer mode 1123.

The detachable liquid chemical driving body 12 is installed in the accommodating space 111 of the portable control body 11 by the user, and the power 113 is supplied to the detachable liquid chemical driving body 12 by the portable control body 11. The detachable liquid medicine driving body 12 has an infusion line 121 (the infusion line 121 stores a liquid medicine 1211), a piezoelectric pump 122 and an information transmission module 123. The piezoelectric pump 122 provides power to transmit the liquid 1211 in the infusion line 121, and the pump is controlled by the control signal 1121 to control the flow of the liquid 1211. In this embodiment, the pump can be piezoelectric. Pump 122, but not limited to this.

The information transmission module 123 has a pump model identification unit 124. The pump model identification unit 124 provides a pump type identification code 1241 to a pump model detection unit 1122 to correspond to one of the liquid medicine transmission modes 1123. . Therefore, the pump type detecting unit 1122 in the portable control body 11 starts to obtain one of the model identification codes 1241 provided by the pump model identifying unit 124 in the detachable liquid medicine driving body 12. The model identification code 1241 represents a variety of different pump types (the liquid medicine transmission mode 1123 is roughly divided into the drug operation mode 1126 (and another set of different types of identification code 1241 anesthetics, cardiotonic drugs, etc.) pump type , blood transfusion operation mode 1124 (and then set the different types of different identification code 1241 phase The pump type of the blood of the heteroemia type or the pump type of the drip operation mode 1125 (the other type of different types of identification code 1241 of physiological saline, glucose solution, protein solution or vitamins, etc.), or, Correction information (a calibration reference for the pump at the factory) is available.

The pump type identification unit 124 of the detachable liquid medicine driving body 11 provides one type identification code 1241 of the piezoelectric pump 122, and each type identification code 1241 is connected with a liquid (for example, a liquid storage bag, a liquid storage bottle or a liquid storage) Each type of liquid medicine (various drugs, various types of blood or various types of drip products) is matched to provide a pump type detecting unit 1122 of the portable control body 11 for detecting and discriminating, preventing disease Misuse of inconsistent liquids leads to delays in treatment and even poisoning. The infusion line 121 of the detachable liquid medicine driving body 12 is connected to the liquid supply tube. The embodiment is represented by a liquid storage bag and a connected infusion tube, but not limited thereto (as shown in FIG. 1B). .

According to the user's selection of the required chemical solution 1211 together with the piezoelectric pump 122 that has been engaged, the detachable liquid chemical driving body 12 is installed in the portable control body 11. If the pump model detecting unit 1122 detects that the model identification code 1241 does not match, the control unit 112 issues a warning signal 1127 warning. If the pump type detecting unit 1122 detects that the model identification code 1241 is met, at the same time, the control unit 112 selects the liquid medicine transmission mode 1123 as various drug operation modes, various blood transfusion operation modes 1124, or various types of drip operation modes.

(Continues Dosage) and so on), without complicated settings, when the liquid 1211 is used, it can be discarded along with the medical supplies, so it will not cause the patient to use the same pump to cause infection, and it is convenient for medical personnel. operating.

Please refer to FIG. 3A and FIG. 3B , which are schematic diagrams of third-party blocks of the liquid medicine transmission monitoring device of the present invention and a partial structure diagram of the flow detecting unit. In the drawings, the embodiments of the second embodiment and the first embodiment are substantially the same, and the same elements and functions are not described herein. The difference is that in the second figure, the information transmission module 123 further has a flow detecting unit 125, and the control unit 112 further stores a plurality of flow data 1128. The flow detecting unit 125 generates a flow rate information 1252 of the chemical liquid flow signal 1252 to the control unit 112. When the drug flow signal 1252 corresponds to one of the flow data 1128, the drug flow is normal. When the liquid flow signal 1252 corresponds to one of the flow data 1128, the flow rate of the liquid is abnormal, and the control unit 112 generates a warning signal 1127 for warning the liquid in the infusion line 121 to leak, block, or contain air. And so on.

The flow detecting unit 125 can have a preheater 1251, a plurality of temperature sensors 1253, 1254, and a temperature difference generated by the first temperature sensor 1253 to the second temperature sensor 1254 flowing through the liquid 1211. According to the measurement, the flow rate of the liquid medicine 1211 in the infusion line 121 is measured. In other words, based on the temperature of the first temperature sensor 1253 flowing in, when the flow rate is slow, the liquid 1211 flows through the preheater 1251 and the heating time is prolonged, and the liquid 1211 flows into the second temperature sensing. The device 1254 can sense the temperature and the temperature is greatly increased. Conversely, when the flow rate is fast, the liquid 1211 flows through the preheater. The 1251 is quickly heated for a short period of time, and the liquid chemical flows into the second temperature sensor 1254 to sense that the temperature is slightly increased. (The path between the chemical solution 1211 flowing into the second temperature sensor 1254 and the preheater 1251 is short, so the temperature of the overflow is extremely negligible). Therefore, when the flow rate of the chemical liquid 1211 is large, the temperature difference is small, and when the flow rate of the chemical liquid 1211 is small, the temperature difference is large.

Therefore, when the liquid medicine 1211 is in the flow phase and the infusion line 121 leaks, the liquid medicine 1211 in the pipeline is originally changed from the flow state to the higher-speed flow state, so the temperature of the second temperature sensor temperature is preset. The temperature difference state is changed to a state in which the temperature difference is low. At this time, the control unit 112 generates a warning signal 1127 to alert the medical staff or the patient. When the chemical solution 1211 is in the stationary phase, the preheater 1251 is turned off, preventing the preheater 1251 from continuously heating the medical solution 1211.

When the liquid medicine 1211 is in the flow phase and the infusion line 121 is blocked, the liquid medicine 1211 in the pipeline is originally changed from the flowing state to the stationary state, so the temperature of the temperature sensor will gradually change to a temperature-free state in the temperature difference state. The state, or directly to the temperatureless state, the control unit 112 generates a warning signal 1127 to alert the medical staff or the patient: when the liquid 1211 is in the flow phase, the infusion line 121 contains air, and the air arrives at the preheater 1251. The liquid-free medium acts as a heat-dissipating medium, so the temperature of the temperature sensor in the pipeline will rise sharply. At this time, the control unit 112 generates a warning signal 1127 to alert the medical staff or the patient.

In addition, the portable control body 11 further has a third telecommunication connection point 1113, and the detachable liquid medicine driving body 12 further has a fourth telecommunication connection point 1203. The third telecommunication connection point 1113 (shown as a PIN hole) is in communication with the accommodating space 111, and the third telecommunication connection point 1113 is located in the accommodating space. The space is between two mutually facing two guiding grooves 1111 (as shown in FIG. 1C).

The fourth telecommunications connection point 1203 (shown as a PIN pin) is located within the opening 1201 and between the two mutually facing rails 120. The guiding rail 120 can be inserted into the guiding slot 1111 and the third telecommunication connecting point 1113 and the fourth telecommunication connecting point 1203 are electrically connected to each other, so that the flow detecting unit 125 generates a chemical liquid flow signal 1252 (medicine flow signal) The temperature sensed by the 1252 switching sensor is compared to the flow data 1128 of the control unit 112 (the flow data 1128 is a preset temperature code). (as shown in Figure 1C).

Please refer to FIG. 4, which is a fourth block diagram of the medical liquid transport monitoring device of the present invention. In the drawings, the embodiments of FIGS. 4 and 3 are substantially the same, and the same elements and functions are not described herein. The difference in the figure is that, in the third figure, the portable control body 11 further has a slot 114, and the slot 114 can be freely selected to be inserted into a blood oxygen concentration measuring module 117 (SpO2). In order to prevent the patient from having a fatal side effect or complication in a coma or incapable condition, especially when the drug delivery device 1 is applied to an anesthetic (PCA) surgery, the patient often has hypoxemia and because of hypoxemia. The disease is easy to induce and aggravate the factors of other diseases.

Please refer to FIG. 5, which is a fifth block diagram of the medical fluid transmission monitoring device of the present invention. In the drawings, the embodiments of the fifth and fourth embodiments are substantially the same, and the same elements and functions are not described herein. The difference in the figure is that, in FIG. 4, the portable control body 11 has a wireless/transmission unit 115 and the control unit 112 stores an infusion process. Record information 1129. The infusion history record information 1129 is transmitted to the outside by the wireless/transmission unit 115 (for example, USB, RS232, Wi-Fi, Bluetooth, RFID, 3G, 4G, WiMAX interface/wireless transmission) for further information. For analysis or reading, the above infusion history record information 1129 may include, but is not limited to, a record of the total output of the drug solution, a record of the interval of the drug solution output, a record of the output value of the drug solution per unit time, and a record of the contents of the physiological monitoring measurement, etc. .
