Detailed Description

Embodiments of the present invention will be described in detail below with reference to fig. 1-4.

In one embodiment, as shown in fig. 1, an infusion drip cup 1 is provided with openings at the upper and lower parts, and a dropping liquid 2 can enter the infusion drip cup through the upper opening of the infusion drip cup and flow out of the infusion drip cup through the lower opening of the infusion drip cup to infuse a patient through a needle.

An intelligent transfusion monitoring device comprises a dropping liquid sensor, a controller 4 and a data transmitter 5; the dropping liquid sensor of the intelligent transfusion monitoring device is arranged on the transfusion drip cup 1 and detects the dropping liquid of the transfusion drip cup. The two dropping sensors are respectively a first dropping sensor 3 and a second dropping sensor 6; for triggering and detecting dripping; the controller 4 adopts a single chip microcomputer to realize data acquisition and analysis; the data transmitter 5 is connected with the gateway through a wireless communication technology to realize transmission of the detection data.

The first dropping liquid sensor and the second dropping liquid sensor are arranged on the surface of the transfusion drip cup at a certain distance. The first dropping sensor and the second dropping sensor are respectively provided with a sending end and a receiving end for sending and receiving light beams, and are respectively arranged at two sides of the transfusion drip cup, preferably in a C shape.

Because the dropping liquid is nearly elliptical form accelerated motion downwards, the dropping liquid surface is the curved surface, and first half and lower half light will appear twice refraction, make the receiving terminal can not receive light, only can penetrate the dropping liquid directly at dropping liquid middle part light, and the wave form of production is unstable. When level data are adopted, two level signals generated by the same dropping liquid are avoided; the amount of the dropping liquid passing through is determined by filtering out the redundant primary level signal, and the amount of the dropping liquid passing through is measured by a dropping liquid sensor, so that the waveform appears unstable. As shown in fig. 2, the graph is a comparison graph of the first drop sensor filter, the lower layer is an original waveform graph, and the upper layer is a filtered waveform graph, wherein the wave trough of the original wave corresponds to the wave crest of the filtered wave, and the wave crest of the original wave corresponds to the wave trough of the filtered wave. As can be seen from the original waveform diagram, because the shape of the water drop is random, the waveform formed later by the drop sensor has noise, for example, the fourth, sixth, eighth, and tenth valleys from right to left. And (3) performing condition filtering through the scanning times and the threshold value to obtain an upper-layer filtered waveform diagram which is a square waveform diagram, wherein clutters of a fourth trough, an eighth trough and a tenth trough in the original waveform are successfully filtered, and because the waveform of the clutter of a sixth trough is large, the waveform of the sixth trough cannot be successfully filtered, and an error signal is generated. Thus, the measured drop throughput is not accurate with this filtration method.

The utility model discloses a two dropping liquid sensors, wherein first dropping liquid sensor still is used for triggering the detection of second dropping liquid sensor, through triggering the formula, further guarantees the rate of accuracy that detects the dropping liquid.

Now, the infrared sensor is used for detailed description, when the infusion operation is carried out, firstly, the dropping liquid sensor is arranged on an infusion drip cup, and the corresponding infusion operation is carried out; when the infrared light beam passes through the first dropping liquid sensor, the infrared light beam is refracted under the shielding effect of the dropping liquid, the infrared ray received by the receiving end of the first dropping liquid sensor is changed, the infrared sensor is utilized to convert the optical signal into an electric signal, and the second dropping liquid sensor is triggered to work, and the infrared sensor is also utilized to convert the optical signal into the electric signal; the electric signal at the receiving end of the dropping liquid sensor is collected through a single chip microcomputer, and the electric signal is converted into a level signal after being amplified and shaped; preferably, in the sampling period of the single chip microcomputer, the original waveform is filtered to form a square wave by setting a threshold value of 0-1V analog quantity; and accurately judging whether the dropping liquid passes through by the comparison and analysis of the signals twice; and data transmission is performed through the data transmitter.

As shown in fig. 2 and 3, the waveform diagrams generated by the improved dual-sensor structure are that, because water drops have randomness in the dropping process, the waveform formed by the first drop sensor is different from the waveform formed by the same water drop on the second drop sensor, after the first drop sensor receives the processed square wave, the second drop sensor waits for the square wave, and only two stable square waves are formed in the dropping time, and the drop is determined. If redundant square waves exist at the time, a filtering mode is also adopted, and whether dripping liquid passes through is accurately judged.

In another embodiment, the first drop sensor and the second drop sensor may employ one or more of an infrared sensor, a red sensor, a blue sensor, or a green sensor. The accuracy of the dropping liquid sensor is further improved by the different sensitivity of different lights.

The dropping liquid is detected in the above mode, and the detection result is transmitted through a data transmitter, wherein the data transmitter is preferably a zigbee chip. As shown in fig. 4, each data transmitter is transmitted to the gateway through the ZIGBEE wireless network; then, the infusion data of each sickbed is transmitted to the nursing station monitoring terminal through the gateway. The nurse station monitoring terminal is connected with the hospital network, matches information in the hospital network and matches corresponding patient information, liquid information and other related information. The emergency treatment reminding can be confirmed according to the corresponding information, or the emergency treatment sequencing can be carried out according to the information, and medical care personnel can be reminded to carry out the treatment according to the corresponding sequencing. The monitoring terminal of the nurse station can see the transfusion condition of each sickbed, including flow rate, start time, estimated end time, reminding time and calling

Can also link into the high in the clouds through nurse station guardianship terminal, the user can carry out real time monitoring through modes such as intelligent terminal's little letter applet, little letter APP, little letter public account. For example: the user accesses the cloud data in a form of scanning the two-dimensional code, and the infusion condition is displayed on the mobile phone terminal; including start time, expected end time, etc.; and can set up functions such as reminding, setting up urgent call according to user's demand.

During the transfusion process, the patient adjusts the flow rate automatically; the flow rate is greatly changed, the single chip microcomputer interrupts and records the current time, the reduction amount of the current time is subtracted from the full volume to obtain the residual volume, then the residual time is refreshed and calculated according to the current interrupt time and the current flow rate, and the predicted infusion completion time is dynamically calculated and refreshed through the algorithm; and refreshing and displaying at the corresponding nurse station monitoring terminal and the mobile phone terminal. Nurse station guardianship terminal is provided with alarm device, changes the velocity of flow when the disease is by oneself, because some medicine have the velocity of flow restriction, in time uploads nurse station guardianship terminal to remind relevant medical personnel through alarm device, judge whether need artificial intervention.

Through monitoring the rise and fall of twice level signal to the level signal who uses first dropping liquid sensor and second dropping liquid sensor carries out contrastive analysis, judges whether have the dropping liquid to get into the infusion drip cup, and according to twice level signal's time interval, sets up the flow velocity of dropping liquid. And then, the infusion residual time is pre-estimated by wirelessly outputting the infusion residual time to a gateway through a ZIGBEE chip, and the pre-estimated result is uploaded to a network.

In another embodiment, when the intelligent infusion monitoring device detects the dropping past, the level signal threshold is set to 1; the signal that the dropping liquid sensor sent is received to the singlechip, confirms that there is the dropping liquid to pass through after the contrastive analysis to monitor terminal through ZIGBEE chip conveying digital signal to nurse station after integrating dropping liquid information. Starting timing, for example, counting drops when the time is 12 o' clock and 0 hour and 0 minute; taking 20 drops/ml as an example, assuming 30 drops counted over 30 seconds, the outflow liquid for 30 seconds is 1.5 ml; a bottle of liquid totaling 500ML, then the expected time for complete infusion is 167 minutes, the expected time for complete infusion is 14: 47. the output to the nurse station is 14: the reminder may be set according to the time of the nurse station, for example, 10 minutes in advance, that is, 14: 37 advance notice and alert the medical personnel to proceed with the treatment. In a multi-bed state, the first-delivery dynamic state can be advanced and reminded; meanwhile, the time of finishing the transmission is synchronized to the mobile phone terminal; the corresponding mobile phone terminal can also set reminding time and reminding mode by itself, and set by itself according to the requirements of users, so that the requirements of different users are met.

Because the prior hospital transfusion reagent is a fixed liquid number, each dropping liquid passing through the drip cup is a fixed value and has three specifications of 10 drops/ml, 15 drops/ml and 20 drops/ml; consequently adopt the utility model discloses a calculation dropping liquid finish time that the scheme can be accurate to remind to the unreasonable velocity of flow of special liquid. Meanwhile, the data are uploaded to the monitoring terminal of the nurse station, so that the workload of nurse patrolling is effectively reduced; through the cloud synchronization information to the mobile terminal, relevant personnel can know the liquid condition at any time and set functions such as reminding and the like.
