Title: System and method of giving an injection of ringer

Description:
BACKGROUND 
     (a) Technical Field 
     The present invention relates to a system and method of giving an injection of Ringer, and more particularly, it relates to a system and method of giving an injection of 
     Ringer which can grasp the living body data of the patient and the Ringer remainder data and automatically control the injection amount or the injection speed of the Ringer, or can inform this to the outside and immediately change the injection condition of the Ringer. 
     (b) Background Art 
     In general, the medicine is injected by using the Ringer bag or the Ringer container in case where a lot of medicine is necessary for the patient in the hospital. Since the Ringer bag recently used is made of vinyl material (Non PVC), there is a disadvantage in that as the Ringer is injected, the void space of the Ringer bag becomes depressurized condition, so that the envelopes of the Ringer bag attach to each other whereby the Ringer injection amount and the remainder amount are not precisely seen. 
     Furthermore, the scale indication spacing differs for each Ringer bag manufacturing company, and the scale does not consist with the Ringer amount so as to present difficulty to the nurse working at the site. 
     The Ringer injection procedure requires long time and in case where the amount of the Ringer injected per unit hour is large, the shock can be generated, and in addition, in case where after all the Ringer is injected, the air flows into the blood vessel, there can be risk detrimental to the patient. Therefore, there is a problem in that the medical team or the protector shall always observe the injection situation of the Ringer and the condition of the patient during the Ringer is injected. 
     Recently, there is the serious nurse lacking phenomenon in the hospital and in such nurse lacking condition, the works such as measuring the body temperature and blood pressure which are not difficult and the works such as replacement and measurement of the Ringer consume the time and the personal are not appropriately used. 
     To remove such inconveniences, in the conventional technologies, many patent applications are presented in which the Ringer injection amount is monitored and adjusted, and when the Ringer injection is completed the warning signal is outputted. 
     However, in such conventional technologies, the Ringer injection to suit the condition of the patient is not carried out based on the living body data of the patient. In addition, in case where the medical team or the protector is not present during the Ringer injection, the Ringer injection condition cannot be immediately changed. Furthermore, there is a problem in that the Ringer remainder limit set value cannot be set, and such set value cannot be warned by step and cannot be informed to the medical team or the protector. 
     Therefore, the present applicant devised the present invention to solve such problems, and there is the Korea registered patent publication 10-1413945 (Title of the invention: the Ringer amount sensing device, published date: 2014/06/30) as the prior art document related thereto.

     Therefore, the system  100  of giving an injection of Ringer according to the present invention can check the Ringer remainder data and the living body data in real time and control, based on this, the opening and closing adjustment section  140  so as to smoothly change the injection amount or the injection speed of the Ringer. 
     In addition, the system  100  of giving an injection of Ringer according to the present invention can further comprise a power supply (not shown) for supplying the electric power necessary for each constructional element. 
     In addition, the system  100  of giving an injection of Ringer according to the present invention can further comprise a display (not shown) for displaying the information on the Ringer or the patient such as the Ringer remainder data, Ringer injection completion expectation time, Ringer injection speed, living body data or the like. 
     By providing a structure of the display in addition to the external instrument  150 , efficient work performance and safety medical service can be provided by enabling the patient, medical team or protector to directly confirm the information on the Ringer or patient visually through the structure of the display. 
       FIG. 3  is a partial perspective view concretely showing the weight estimation section  110 , the control section  130 , and the opening and closing adjustment section  140  by enlarging a portion of  FIG. 1 . As shown in FIG. 3 , the weight estimation section  110  can measure the weight of the Ringer bag  101  or estimate the remainder of the Ringer. The weight estimation section  110  can measure the weight of the Ringer bag  101  and estimate the data of the remainder of the Ringer in real time, and signalize and transmit them to the control section  130 . 
     The system  100  of giving an injection of Ringer according to the present invention can use a weight measurement sensor (not shown) to measure the weight of the Ringer remaining in the Ringer bag  101 . The weight measurement sensor can be provided in the weight estimation section  110 . The weight measurement sensor can be formed in a form of hanging the Ringer bag  101 , or can obtain the weight of the Ringer bag  101  or the Ringer remainder data by being connected to the structure from which the Ringer bag  101  is hung. 
     As the weight measurement sensor, a spring sensor, infrared ray sensor, optical sensor, magnetic field sensor, liquid sensor, camera or load cell (weight sensor) can be used to measure the weight. Therefore, although the present invention uses the load cell to measure the weight of the Ringer bag  101  or the Ringer remainder data, however, is not limited thereto and other sensors can be used in the weight estimation section  110 . 
     The opening and closing adjustment section  140  can comprise a motor  141  actuated according to the Ringer remainder data or the living body data, and a tube opening and closing section  142  which is actuated by the motor  141  and which adjusts the injection amount or the injection speed of the Ringer by pressurizing the Ringer tube  103 . 
     The opening and closing adjustment section  140  can further comprise an auxiliary medicine removal/attachment section  143  providing the medicine or injection necessary for the patient, and the auxiliary medicine removal/attachment section  143  can be controlled through the external instrument  150  or by the medical team, protector, or patient. 
     The opening and closing adjustment section  140  can comprise the motor  141  and the tube opening and closing section  142  to adjust the degree of opening and closing of the fluid passage through which the Ringer of the Ringer tube  103  flows. At this time, in addition to the motor  141  and the tube opening and closing section  142 , the auxiliary medicine removal/attachment section  143  can be installed proximally at one side so as to provide the medicine as necessary according to the condition of the patient and can control this. 
     At this time, the tube opening and closing section  142  is actuated by the motor  141 , so as to control the flow of the Ringer flowing in the Ringer tube  103  thereby control the injection amount or injection speed of the Ringer. 
     In addition, the tube opening and closing section  142  can be formed by a rack-pinion, lead screw, linear compression bar, valve or plate or the like, is not limited to this, and any means which can adjust the flow of the Ringer flowing in the Ringer tube  103  can be used. 
     In the auxiliary medicine removal/attachment section  143 , a syringe which includes an auxiliary medicine which should be injected without fail to the patient in addition to the Ringer can be stored. In case the medical team should inject the auxiliary medicine to the patient, they can set the auxiliary medicine injection time or injection amount through the external instrument  150 . 
     The external instrument  150  can be provided as a radio communication instrument so as to receive the input data set by the protector of the patient or the medical team, or the first communication section  135  or the second communication section  145  can receive the input data and manually adjust the injection amount or injection speed of the Ringer. 
     Therefore, in the present invention, the control section  130  estimates the injection amount or injection speed of the Ringer appropriate to the patient provided by the weight estimation section  110  and the data collection section  120  and automatically adjusts this, or in case where the input data are input by the external instrument  150 , the injection amount or injection speed of the Ringer can be manually adjusted by the medical team or the protector. 
     The first communication section  135 , in case where the Ringer remainder data is equal to or below the primary limit or the secondary limit of the Ringer remainder, can send a warning signal to the external instrument  150  or can receive the input data input by the external instrument  150 . At this time, the data of the injection amount or injection speed of the Ringer changed by the control section  130  can be sent to the second communication section  145 . 
     That is, the second communication section  145  can receive the data of the injection amount or injection speed of the Ringer estimated by the control section  130 . 
     The external instrument  150  receives the Ringer remainder data or the warning signal transmitted from the first communication section  135 , and thereafter the medical team or the protector can input the input data and again send the instruction to the first communication section  135 . 
     Therefore, the system  100  of giving an injection of Ringer according to the present invention transmits in real time the weight data periodically through the communication network upon the decrease of the weight according to the injection of the Ringer, whereby the server can immediately monitor the injection situation of the Ringer. In addition, there is an advantage in that in case where an abnormal injection occurs, the warning signal is generated so that the medical team can efficiently manage the patient. 
     The system  100  of giving an injection of Ringer according to the present invention can further comprise a data storage section  160  for storing the living body data or the Ringer remainder data transmitted by the first communication section  135  or the second communication section  145 . 
     Specifically, the data storage section  160  can store the Ringer related data including the history of injection of the Ringer or the medicine to the patient or the like, the living body data obtained from the patient, or the input data input from the external instrument  150 . Accordingly, the entire confirmation as the contents of personal history of the patient or the injection data becomes possible. 
     The data transmitted or received between the first communication section  135 , the second communication section  145 , and the external instrument  150  can be transferred to the data storage section  160 . The first communication section  135 , the second communication section  145 , and the external instrument  150  can use a ZigBee, radio LAN module, Bluetooth, WIFI, UWB or the like as a radio communication module for collecting the data. 
     The operation of the system  100  of giving an injection of Ringer according to the present invention will be concretely described below. 
     The system  100  of giving an injection of Ringer according to the present invention can set the limit of the Ringer, compare the Ringer remainder and the limit, send the warning signal of the result to the outside by stages. Thereafter, the medical team or the protector confirms this, and then compare the input data and the Ringer remainder data estimated by the weight estimation section  110 , and provide the injection amount or injection speed most preferable for the patient based on the preset information. 
     Therefore, the present invention estimates in real time the data of the injection and sends the warning to the external instrument  150 , so that the medical team or the protector can rapidly adjust or set the injection condition at the external instrument  150  remotely. A priority setting section  131  discriminates the priority among the set input data and the Ringer remainder data, and actuates the opening and closing adjustment section  140  through the discriminated data so as to adjust the injection amount or injection speed of the Ringer to be appropriate to the patient. 
     The control section  130  can set the primary limit or the secondary limit about the Ringer remainder or the remainder weight, and can send the warning signal to the external instrument  150  by stages in case where the Ringer is equal to or below the primary limit or the secondary limit. 
     At this time, the medical team or the protector having received the warning signal can input the input data through the external instrument  150 . Accordingly, the control section  130  can receive the input data transmitted from the external instrument  150 . 
     That is, the control section  130  can generate the first step or second step warning signal about the primary limit or secondary limit and transmit it to the external instrument  150  in case where the remainder of the Ringer or the remainder weight is equal to or below the primary limit or the secondary limit. 
     The primary limit or secondary limit about the remainder of the Ringer or the remainder weight can be flexibly set by the medical team for each patient without limitation of the place or the time according to the experience or the work situation of the medical team or the condition of the patient. In addition, the primary limit or secondary limit about the remainder of the Ringer or the remainder weight can be set as %, cc, weight or time based on the remained Ringer remainder data. 
     The warning signal plays a role of informing the protector or the medical team of the lack of the Ringer remainder, and carries out the warning sound, warning comment or warning indication or provides visually the information on the Ringer remainder. 
     In addition, the control section  130  can immediately set the warning signal to the medical team or the protector in advance in case where the patient is in emergency situation (power failure, instability of the patient&#39;s pulse, or the like) or a problem about the Ringer injection occurs, besides the case where the remainder of the Ringer or the remainder weight is equal to or below the primary limit or the secondary limit. 
     The control section  130  can comprise the priority setting section  131  which receives the input data input to the external instrument  150  by the medical team or the protector and discriminates the priority among the input data or the Ringer remainder data. 
     That is, the control section  130  can comprise the priority setting section  131  which discriminates the priority among the input data input to the external instrument  150  by the medical team or the protector or the Ringer remainder data measured by the weight estimation section  110 . 
     In the system  100  of giving an injection of Ringer according to the present invention, the control section  130 , during the injection of the Ringer, can receive in real time the input data input to the external instrument  150  by the medical team or the protector (manual manner), or receive in real time the Ringer remainder data provided by the weight estimation section  110  (automatic manner). The priority setting section  131  of the control section  130  can discriminate the priority among these data based on the preset information and determine the injection amount or injection speed of the Ringer appropriate to the patient. 
     In the meantime, at the time of generation of the warning signal, the cases may be classified into a case where the medical team or the protector response within the preset time after the warning signal and a case where the medical team or the protector does not response. That is, the operation can be classified into a case where the input data are input and a case where the input data are not input. 
     After the warning signal is generated, the priority setting section  131  can preferentially process the input data directly input by the medical team or the protector in case where the input data are input to the external instrument  150  during the preset time. On the other hand, the priority setting section  131  can automatically close the tube opening and closing section  142  or reduce the injection speed of the Ringer by the control section  130  in case where the input data are not input from the external instrument  150  during the preset time. 
     That is, if the medical team or the protector cannot input the input data through the external instrument  150  within the preset time after the warning signal is sent to the external instrument  150 , the control section  130  can automatically recognize this as an emergency situation and close the tube opening and closing section  142  or reduce the injection speed of the Ringer based on the Ringer remainder data. This can prevent the danger of the air going into the blood vessel after all the Ringer is injected by immediately interrupting by force the Ringer injected to the patient or by reducing the injection speed. 
     Therefore, the system  100  of giving an injection of Ringer according to the present invention can interrupt the injection while all of Ringer is not injected but a certain amount is remained by the warning signal for the primary or the secondary step about the preset primary limit or secondary limit. That is, there is an advantage in that since it is not necessary to remove the syringe needle directly under the condition in which the Ringer remains a certain amount, there is no significant problem in the safety of the patient, and the medical team can treat the more urgent patient or service. 
       FIG. 4  is a drawing showing in detail a screen of the external instrument  150  by enlarging B portion of  FIG. 1 . According to what shown in  FIG. 4 , the living body data of the patient, the remainder amount of the Ringer, the injection speed, the injection completion expectation time or the medical team in charge is displayed on the external instrument  150 , and the protector or the medical team can adjust at least one among the remainder amount of the Ringer, the injection speed of the Ringer, the injection completion expectation time of the Ringer through the external instrument  150 . 
     The external instrument  150  is a radio communication instrument and can be realized by a tablet PC or a smart phone or the like. As shown in  FIG. 4 , the name of the patient, the nurse in charge, the injection rate, the injection speed, the primary and secondary limit of the Ringer, the primary and secondary completion time of the Ringer, the pulse, the blood pressure, the temperature or the like can be set or confirmed at the tablet PC or the smart phone screen being the external instrument  150 . 
     Therefore, the system  100  of giving an injection of Ringer according to the present invention does not require one to go to the hospital room to confirm the Ringer remainder data, the living body data, the injection speed, the injection rate or the injection completion time as well as can adjust the injection speed, the injection rate or the injection completion time while the Ringer is injected by using the external instrument  150 . 
     In addition, if the Ringer remainder amount reach the primary limit or the secondary limit, the external instrument  150  receives the warning signal from the control section  130  and knows this in advance, and inputs the set data according thereto and sends the instruction signal to the control section  130  so as to adjust the injection amount of the Ringer, the injection speed or the injection completion time or interrupt the injection of the Ringer by sending the instruction signal to the control section  130 . 
       FIG. 5  is a flow diagram showing a method S 200  of giving an injection of Ringer according to an embodiment of the present invention. According to what shown in  FIG. 5 , the method S 200  of giving an injection of Ringer using the system  100  of giving an injection of Ringer according to the present invention can comprise: a weight estimation step S 210  for measuring the weight of the Ringer bag or estimating the Ringer remainder by a weight estimation section; a data collection step S 220  for collecting the living body data of the patient by being connected to the body of the patient by wire or wirelessly; a control step S 230  for setting the injection amount or the injection speed of the Ringer by using the data received from the weight estimation step S 210  or the data collection step S 220 ; an actuation step S 240  for adjusting the actuation condition of an opening and closing adjustment section  140  installed at a Ringer tube according to the injection amount or the injection speed of the Ringer estimated by the control step S 230 ; and a setting step S 250  in which the injection amount or the injection speed of the Ringer is set by receiving the input data from an external instrument  150 . 
     The control step S 230  can control the injection amount or the injection speed of the Ringer to suit the patient based on the data obtained by the weight estimation step S 210  or the data collection step S 220 . In addition, the control step S 230  can set a primary limit and a second limit according to the Ringer remainder or the remainder weight. 
     The control step S 230  can comprise a warning step S 270  for warning the external instrument in case where the Ringer remainder or the remainder weight is equal to or below the primary limit or the secondary limit, and a priority discriminating step S 260  for discriminating the priority among the input data set by the setting step S 250  and the Ringer remainder data estimated by the weight estimation step S 210 . 
     The priority discriminating step S 260  can preferentially process the input data input from the external instrument in case where the input data are input from the external instrument during the preset time after the warning step S 270 , and can automatically close the tube opening and closing section or reduce the injection speed of the Ringer by the control step S 230  in case where the input data are not input from the external instrument during the preset time. 
     The method S 200  of giving an injection of Ringer according to an embodiment of the present invention follows the order described below. 
     The medical team inserts the syringe needle to the patient so as to connect the Ringer bag and estimates the Ringer remainder amount data in real time (weight estimation step S 210 ). At this time, a living body data means is connected to the patient by wire or wirelessly and collects the living body data of the patient (data collection step S 220 ). The injection amount or the injection speed of the Ringer is set based on the 
     Ringer remainder data or the living body data and the signal of the injection amount or the injection speed of the set Ringer is sent to the opening and closing adjustment section (control step S 230 ). The injection amount or the injection speed of the Ringer is adjusted by adjusting the opening and closing of the Ringer tube (actuation step S 240 ). As the Ringer is injected, if the Ringer remainder or the remainder weight falls to or below the preset primary or secondary limit, the warning signal is sent to the external instrument (warning step S 270 ). The input data is set which lets the injection amount or the injection speed of the Ringer to be changed if the medical team or the protector receives the warning signal through the external instrument, or through the information usually received in real time (setting step S 250 ). The injection amount or the injection speed of the Ringer is adjusted by discriminating the priority among the input data and the Ringer remainder data (priority discrimination step S 260 ). 
     The present invention has been described with reference to limited embodiments and the drawings thereof, however, the present invention is not limited to the embodiments described above, and it will be appreciated by those skilled in the art that various amendments and changes may be made.
