In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.
Referring to fig. 1, the present invention discloses a real-time monitoring system of an administration feeding set for delivering a liquid such as a drug solution to a patient, including a mounting main body 1 and a tube system 2 of a hose, the tube system 2 being fixed to the mounting main body 1.
Specifically, the piping system 2 is provided with an upstream mounting member 5 and a downstream mounting member 6, the mounting body 1 is provided with a first fixing portion and a second fixing portion, and the upstream mounting member 5 and the downstream mounting member 6 are respectively placed on the first fixing portion and the second fixing portion, thereby mounting the piping system 2 on the mounting body 1.
Still include first sensor 3, first sensor 3 is close to first fixed part and keeps away from the setting of second fixed part for the liquid of the first fixed part annex of induction monitoring. The first sensor 3 is correspondingly connected with the pipe system 2 to sense the flowing condition of the liquid in the pipe system 2, and the corresponding connection can be a contact connection or a non-contact connection, but the non-contact connection also needs to ensure that the target pipe system 2 is within the sensing range of the sensor, so that the sensor can normally monitor the target pipe system 2.
The liquid sensor also comprises a second sensor 4, wherein the second sensor 4 is close to the second fixing part and far away from the first fixing part and is used for sensing and monitoring liquid of the accessory of the second fixing part. Similarly, second sensor 4 is coupled to tubing 2 to sense the flow of fluid within tubing 2, and the coupling may be a contact coupling or a non-contact coupling, but the non-contact coupling also ensures that target tubing 2 is within the sensing range of the sensor, so that the sensor can monitor target tubing 2 properly.
The device further comprises a controller which is electrically connected with the first sensor 3 and the second sensor 4 and used for receiving the sensing data of the first sensor 3 and the second sensor 4. The controller also makes corresponding control decisions based on the sensed data of the first sensor 3 and the second sensor 4. Specifically, the method comprises the following steps:
when liquid flows in the piping system 2, the first sensor sends a first sensing signal by sensing the liquid, and the second sensor continuously obtains the flow parameters of the liquid by sensing the liquid;
when there is no liquid flow in the piping 2, since the first sensor is disposed upstream of the piping 2, there are two cases, one is clogging of the upstream piping 2, and the other is no liquid flow in the piping 2; therefore, the first sensor cannot sense the liquid so as to send out a second sensing signal; the controller sends out a prompt signal that no liquid flows or a first blockage prompt signal according to the second sensing signal; the first occlusion cue signal is typically identified as an upstream tubing 2 occlusion;
when the liquid in the pipe system 2 is blocked, because the blockage can cause various parameters of the liquid in the pipe system 2 to change, such as pressure increase, impurity increase and the like, when the controller judges that the difference value between the circulation parameters acquired by the second sensor exceeds a set threshold value, the pipe system 2 is considered to be blocked; and since the second sensor is disposed downstream of tubing 2, a second occlusion-prompting signal is emitted, which is typically identified as an occlusion in downstream tubing 2.
The first sensor 3 and the second sensor 4 may be ultrasonic sensors, pressure sensors, displacement sensors, or photoelectric sensors, but are not limited to the above-mentioned types of sensors.
In a preferred embodiment, the first sensor 3 is an ultrasonic sensor. When the liquid in the pipeline normally flows, the ultrasonic sensor sends out a high signal. When no liquid exists in the pipeline, the ultrasonic sensor sends a low signal, the signal of the ultrasonic sensor is collected in real time through the controller, when the low signal is sent, the blockage at the front end of the pipeline system 2 can be judged, or the liquid is used up, and correspondingly, the alarm prompt is carried out to warn a guardian.
The second sensor 4 is a pressure sensor. When liquid in the pipeline normally flows, the pipeline system 2 is contacted with the pressure sensor to generate m pressure values; when the lower end of the piping system 2 is blocked, liquid is continuously input into the front end of the piping system, so that the hose is expanded. The expanded hose can extrude the pressure sensor so that the pressure value output by the pressure sensor is increased, and m + n pressure values are output. The controller judges the blockage of the tail end of the pipeline according to the difference of the front pressure value and the rear pressure value. When the blockage is relieved, the pressure value is restored to the initial value again, and the equipment monitors and judges that the liquid normally flows.
The liquid re-piping system 2 is inevitably fluctuated in pressure value, so the size of the difference value of the pressure value is limited, and the blockage is judged only when the difference value exceeds a certain threshold value, otherwise, the liquid re-piping system is considered to be in a normal liquid circulation condition.
In other embodiments, similarly, when the first sensor 3 is a light sensor, the presence or absence of fluid in the tube 2 is detected by the light sensor. When the second sensor 4 is a displacement sensor, it is determined whether or not there is clogging by determining a displacement value of the liquid in the normal flow condition and a displacement value of the liquid in the clogging condition.
Preferably, in the preferred embodiment shown in fig. 1, the first sensor 3 is disposed between the first fixing portion and the second fixing portion, and the second sensor 4 is disposed between the first fixing portion and the second fixing portion, so as to make the structure more compact.
In other embodiments, the first sensor 3 may also be disposed at an end of the first fixing portion away from the second fixing portion; the second sensor 4 may also be disposed at an end of the second fixing portion away from the first fixing portion.
Further, still include revolving part 7, piping 2 passes through first fixed part in proper order, bypasses revolving part 7, passes through the second fixed part setting. The first sensor 3 is arranged between the first fixed part and the rotating part 7 and is correspondingly connected with the pipe system 2 so as to sense the flowing condition of the liquid in the pipe system 2 between the first fixed part and the rotating part 7; the second sensor 4 is arranged between the rotating member 7 and the second fixed part and is correspondingly connected with the pipe system 2 to sense the flowing condition of the liquid in the pipe system 2 between the rotating member 7 and the second fixed part.
Preferably, the first sensor 3 and the second sensor 4 are disposed on the mounting body 1 and are in contact with the piping 2 to sense the flow of the liquid in the piping 2.
In other embodiments, first sensor 3 and second sensor 4 may be in non-contact connection with tubing 2, as long as the flow through tubing 2 can be monitored normally.
Preferably, a flow stop is included and is connected to the piping system 2 for shutting off the flow of the liquid in the piping system 2. The choke is also connected with a controller, and the controller can control the opening of the choke according to the sensing signals of the first sensor 3 and/or the second sensor 4. For example, when a blockage occurs in the piping system 2 or no liquid exists in the piping system 2, even if the flow of the liquid in the piping system 2 is shut off, a failure is prevented.
Preferably, in some preferred embodiments, the first and second fixing portions include a clamping member, and the upstream and downstream mounting members 5 and 6 are clamped by the clamping member so as to be fixed to the first and second fixing portions.
In other preferred embodiments (e.g., the embodiment shown in fig. 1), the first and second fixing portions are recesses, and the upstream and downstream mounting elements 5 and 6 are confined in the recesses so as to be fixed to the first and second fixing portions.
Referring to fig. 2, the present invention also discloses a method for real-time monitoring of an administration feeding set, which is used in the above real-time monitoring system, wherein liquid flows through the piping 2 at the position of the upstream installation part 5, the piping 2 at the position of the rotating part 7 and the piping 2 at the position of the downstream installation part 6 in sequence. The real-time monitoring method comprises the following steps:
when liquid flows in the piping system 2, the first sensor sends a first sensing signal by sensing the liquid, and the second sensor continuously obtains the flow parameters of the liquid by sensing the liquid; the first sensing signal indicates that the liquid flows normally, for example, the first sensing signal is received by the controller and then sends out a prompt which is embodied as a green light indicator lamp.
When no liquid flows in the piping system 2, the first sensor cannot sense the liquid so as to send a second sensing signal; the controller sends out a prompt signal of no liquid circulation or a first blockage prompt signal according to the second induction signal and controls the opening of the flow plug so as to cut off the liquid circulation in the piping system 2. The second sensing signal indicates that the liquid flows abnormally, for example, a user operation interface of the main body 1 displays that the liquid is used up or the front end of the pipeline is blocked, and a red light warning lamp is emitted.
When the liquid in the piping system 2 is blocked, the controller judges that the difference value between the circulation parameters acquired by the second sensor exceeds a set threshold value, and then a second blocking prompt signal is sent out; and controls the opening of the flow stop to shut off the flow of liquid through the piping 2. For example, a user operation interface of the installation main body part 1 displays "the rear end of the pipeline is blocked" and a red light warning lamp is emitted.
For the detection process of the second sensor, the invention provides a preferred embodiment, a three-stage detection method is adopted, 3 values of a, b and c are preset, and when min/max > is detected to be a, the condition that no blockage occurs in the pipe is indicated; when min/max < b is detected, indicating that the pipe is blocked; when min/max > is detected, c indicates that the pipe is blocked continuously. Therefore, when only a and b appear, the normal transfusion state is realized; when the 3 data of a, b and c continuously appear and c continues for a period of time, the end of the pipeline is judged to be blocked.
It should be noted that the above-mentioned flow parameters refer to parameters in the flow process of many liquids, such as pressure value, impurity clarity, displacement value (flow rate), etc.
Preferably, since the liquid re-piping system 2 inevitably has fluctuation of parameters (such as pressure values), the time for shifting the parameters (such as pressure values) needs to be limited, so that the controller determines that the difference value between the circulation parameters acquired by the second sensor exceeds the set threshold value and lasts for more than the preset time period, and then sends out the second blockage prompt signal, otherwise, the liquid re-piping system is regarded as a normal liquid circulation condition.
By the real-time monitoring system and the method, people do not need to be assigned to watch when the liquid normally flows. Only when no liquid exists or the liquid can not flow, the information is sent, human intervention is carried out, and after the problem is solved, the liquid can flow normally.
It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
