[0024] See attached Figure 1-2, shown is a clip-type dripping rate monitor, the monitor 1 includes a clamping member 2, and a capacitance detection antenna 6, a battery assembly 5 and a main control assembly 4 installed on the clamping member 2; the clamping member 2 includes a first clamping plate 21 and a second clamping plate 22 which are assembled and connected, the first clamping plate 21 and the second clamping plate 22 can be elastically opened and closed to achieve a clamping action, and the inner surface of the clamping end 20 of the first clamping plate 21 is provided with a receiving groove 3 for accommodating an infusion tube drip pot 100; the capacitance detection antenna 6 includes an antenna left pole and an antenna right pole, and the antenna left pole and the antenna right pole are correspondingly distributed on both sides of the receiving groove 3 to detect the capacitance change when the liquid in the drip pot 100 drips; the battery assembly 5 is electrically connected to the main control assembly 4 to provide power for the operation of the monitor; the main control assembly 4 is configured with a communication unit for transmitting data, and the main control assembly 4 is electrically connected to the capacitance detection antenna 6 to analyze the dripping speed in the drip pot 100 according to the capacitance change information fed back by it, and upload the dripping speed information via the communication unit.

[0025] During use, the operating end of the clamping member 2 is applied with force so that the clamping end 20 is opened, and the clamping end 20 is clamped to the infusion tube, and the drip pot 100 is just embedded in the accommodating groove 3 inside the clamping end 20, and the antenna left pole and the antenna right pole symmetrically distributed on both sides of the accommodating groove 3 monitor the liquid dripping in the drip pot 100, so as to learn that the capacitance value changes, and the capacitance value change information is sent to the main control component 4, and the main control component 4 calculates the dripping speed, and usually 50-80 drops / minute is the normal infusion speed. Specifically, when a drop of liquid drips in the drip pot 100, the capacitance value generated by its entry and exit electric field is waveform-changing, and the corresponding waveform curve has frequency, and the fixed frequency corresponds to the fixed dripping speed (this part is the existing principle, and it is not expanded and repeated). After calculating the dripping speed, via the communication unit, the communication modes such as Bluetooth upload this information to the server, so that the medical staff can be informed in time.

[0026] In some embodiments, the middle parts of the first clamping plate 21 and the second clamping plate 22 are connected to each other by means of the longitudinal axis and the axial hole respectively arranged on the two clamping plates, and the longitudinal axis is penetrated by a torsion spring, and the upper leg and the lower leg of the torsion spring are respectively against the first clamping plate 21 and the second clamping plate 22. If the longitudinal axis is installed on the second clamping plate 22, a plurality of axial holes are arranged on the first clamping plate 21, and the longitudinal axis is penetrated by the plurality of axial holes, and force is applied to the operating ends of the first clamping plate 21 and the second clamping plate 22, the first clamping plate 21 rotates along the longitudinal axis, so that the clamping ends 20 of the first clamping plate 21 and the second clamping plate 22 are opened to clamp the drip tube, and at this time, the upper leg and the lower leg of the torsion spring are in an energy storage state under force, so as to apply elastic force so that the clamping end 20 maintains a clamping force of sufficient strength.

[0027] In some embodiments, the second clamping plate 22 is provided with an observation window corresponding to the containing tank 3. Through the observation window, the user can directly see the drip pot 100 in the containing tank 3, so as to observe the dripping condition.

[0028] In some embodiments, the first clamping plate 21 includes an inner bottom plate 210 and an outer cover plate 211, wherein the outer cover plate 211 is buckled onto the inner bottom plate 210, and a receiving cavity is formed therebetween, in which the capacitance detection antenna 6, the battery assembly 5, and the main control assembly 4 are installed. The inner bottom plate 210 and the outer cover plate 211 can be assembled by means of snaps, screws, or other connection methods, and a receiving cavity with a receiving function is formed therebetween, in which the capacitance detection antenna 6, the battery assembly 5, and the main control assembly 4 can be fixed therein by common methods such as nesting, bonding, or screws. An exposed charging port can be provided on the first clamping plate 21, and the charging port is electrically connected to the battery assembly 5 for charging the battery assembly 5.

[0029] In some embodiments, a portion of the inner bottom plate 210 is recessed toward the outer cover plate 211 to form a longitudinally through-going groove body 7, and the top and bottom of the outer cover plate 211 are provided with notches 2110 corresponding to the upper and lower ends of the groove body 7 respectively; the receiving groove 3 is formed at the lower part of the groove body 7. The clamping member 2 is clamped on the infusion tube, the drip pot 100 is embedded in the receiving groove 3, and the tube body connected to the upper end of the drip pot 100 is embedded in the groove body 7, and the notches 2110 at the upper and lower ends can allow the upper and lower tube bodies of the drip pot 100 to pass through. Preferably, the upper part of the groove body 7 is narrower than the lower part (receiving groove 3) to better fit the infusion tube.

[0030] In some embodiments, a capacitive antenna electrically connected to the main control component 4 is disposed on the upper portion of the tank 7 to monitor the capacitance change in the infusion tube at the upper end of the drip pot 100, and to feed back to the main control component 4, so as to analyze whether there is liquid in the infusion tube. The capacitive antenna can be installed in the accommodating cavity to monitor the infusion tube, and the capacitance in the infusion tube will change accordingly according to the presence or absence of liquid, thereby knowing whether there is still liquid in the infusion tube, so that medical staff can know this information.

[0031] Preferably, an electric locking member is disposed on the upper portion of the tank body 7, and the electric locking member is electrically connected to the main control assembly 4, so as to lock and close the infusion tube when there is no liquid in the infusion tube.

In the infusion state, the locking block 80 installed on the output shaft is in a recovery state, and the liquid in the infusion tube flows normally. When it is detected that there is no liquid in the tube, the motor 8 is started to push the output shaft to the drip tube through the window 70, and the drip tube is squeezed closed to prevent the infusion from returning blood. When the infusion is performed again, the motor 8 is started to pull the output shaft back and withdraw the locking block 80. Furthermore, the front end of the locking block 80 has a pointed block. The pointed block has a small contact area with the drip tube, and the squeezing force is greater, which can better close the drip tube.

[0033] The main control component 4 includes a Bluetooth single chip microcomputer, and the Bluetooth single chip microcomputer is equipped with a capacitance detection circuit, and the capacitance detection circuit is electrically connected to the capacitance detection antenna 6. For example, the main control component 4 uses a PCB board, and a Bluetooth single chip microcomputer is arranged on the PCB board. The Bluetooth single chip microcomputer communicates with a high-precision MC12T capacitance detection chip (produced by Minyuan Sensing Technology Co., Ltd.) in the capacitance detection circuit in real time through I2C. The MC12T chip collects the capacitance value change of the drip pot 100 space through the high-precision capacitance detection antenna 6, and feeds the change value back to the Bluetooth single chip through I2C. The Bluetooth single chip microcomputer calculates the dripping speed according to the algorithm.

[0034] In summary, the clip-type drip rate monitor 1 is fixed to the infusion tube by a clamping method, and the drip pot 100 is embedded in the accommodating groove 3 in the clamping posture. The capacitance detection antenna 6 on both sides of the accommodating groove 3 detects the change of the capacitance value in the space of the drip pot 100, and the dripping speed in the drip pot 100 is calculated according to the change, and fed back to the server. The improved drip rate monitor 1 is simple and convenient to operate, and the capacitance monitoring method can quickly and effectively know the infusion status.
