Description

Ringer Sap End Notification System {Intravenous Sap End Notification System}

The present invention relates to a system for notifying the end of Ringer's infusion, and more particularly, by detecting whether or not Ringer's infusion is injected into each patient, determining and displaying the remaining infusion time, and notifying nurses and caregivers that the end of infusion is imminent. It relates to a Ringer's fluid end notification system that informs and checks whether the injection is normally performed and notifies when a problem occurs.

Infusion of Ringer's fluid is used when injecting drugs into patients in hospitals, and nurses have directly managed from the time of preparation of injection to the end of injection and replacement.

If the infusion is left unattended even after the infusion has been completed, there is a possibility that the patient's blood will flow backward.

However, since the number of patients managed by one nurse is large and the end point of infusion is different for each patient, it is not easy to manage all of them with only one nurse's judgment.

In addition, there is a problem that may occur when the infusion tube is dislodged, clogged or twisted due to carelessness of patients during injection.

As a prior art for solving these problems, Korean Patent Registration No. 10-0922839 [Patent Document 1] is disclosed.

In [Patent Document 1], an infusion injection device including a hanger for fixing by hanging a fixing hook installed on the outside of a fluid storage container containing fluid to be injected to a patient and a transport vinyl plate for fluid inserted into the inlet side of the fluid storage container In the case where the infusion storage container is hung on a fixed hanger, the weight change per unit time of the infusion container is measured using a pressure sensor and a microcomputer installed on the hanger to calculate the injection rate to alert that the injection is too fast or slow than the set value. Disclosed is an intravenous injection state alarm device for an infusion solution comprising an injection amount monitoring device unit that calculates an estimated time for completion of injection and emits a notification signal to the outside when the weight of the container falls below a set reference value.

However, the above-described conventional technology can perform the functions of calculating the residual amount of fluid and sounding an alarm, but when injecting Ringer's fluid to a patient with reduced mobility, a guardian is present in the hospital room to check whether the injection of Ringer's fluid is normally performed. There was the inconvenience of having to reside in the hospital or have a nurse check the status of Ringer's fluid injection.

Figure 2 is a block diagram of the Ringer's infusion termination notification system according to an embodiment of the present invention.

Referring to FIG. 2 , the Ringer's fluid end notification system according to an embodiment of the present invention may include a fluid measuring device 100, a server 200, a display unit 300, and a terminal 400.

Fluid measuring device 100 may measure information about the Ringer's fluid injected into the patient.

The fluid measuring device 100 detects the fall of the Ringer's fluid injected into the instillation chamber 20, calculates information about the Ringer's fluid from the detected information, and transmits the calculated information to the server 200.

Information on the Ringer's fluid measured by the fluid measuring device 100 may include whether or not the Ringer's fluid is injected, the injection rate, the remaining amount, and the remaining time.

Whether or not the Ringer's sap is injected relates to whether the Ringer's sap is being injected into the drip chamber 20 from the Ringer's sap container 10.

This is because it can be seen that when the Ringer's solution is injected into the drip chamber 20 from the Ringer's solution container 10, it is injected into the patient's blood from the injection tube 30.

The infusion rate relates to how much Ringer's solution is injected into the patient's blood vessel per unit time.

The remaining amount relates to the amount of Ringer's Sap remaining in the Ringer's Sap container (10).

The server 200 may be connected to one or more fluid measuring devices 100 and wireless communication method to receive and store information determined from the fluid measuring device 100 in real time.

Each fluid measuring device 100 has a unique number and thus can be distinguished from the server 200, information received from the fluid measuring device 100 can be classified into information corresponding to each unique number.

The wireless communication method may be various as a method for wirelessly transmitting data, and includes Wi-Fi, Bluetooth, Zigbee, Wimax, WCDMA (wideband division multiple access), LTE (long term evolution) ) and the like may be used, and a wireless communication method described below may also be the same method as above.

The display unit 300 may receive information from the server 200 and display information stored in the server 200 .

The display unit 300 may be provided at a location where medical staff including nurses reside so that medical staff including nurses who manage IVF can easily check.

The information displayed on the display unit 300 may include the personal information of the patient to whom each Ringer's fluid is injected, the type and volume of the injected Ringer's fluid, the remaining amount, and the remaining time.

Personal information of the patient may include name and age, and may be pre-entered into the server 200 .

The type and volume of the injected Ringer's sap may also be input to the server 200 in advance before injecting the patient.

The remaining amount of Ringer's sap can be expressed in ml and can be expressed as "remaining amount 300ml".

The remaining time may be displayed in hours and minutes, so that, for example, "remaining time 1 hour 37 minutes" may be displayed.

The terminal 400 may access the server 200, display stored information, and receive notification from the server 200 before a certain time before the end of injection.

The terminal 400 may be a smartphone, PC, laptop, PDA, or a dedicated terminal 400 used in this system, and the terminal 400 may be connected to the server 200 in a wireless communication method.

The terminal 400 may receive information from the server 200 through an application or web page access, and the received information includes the patient's personal information displayed on the display unit 300, the type, volume, and It may include remaining amount and remaining time until completion.

The terminal 400 is portable and can receive information from the server 200 even when it is far away from the server 200 when using a communication network of a communication operator such as WCDMA or LTE rather than short-distance communication.

The server 200 may transmit a notification to the terminal 400 when the end of Ringer's fluid injection is imminent based on the information provided from the fluid measurement device 100 .

The imminent time point can be set in advance, and a plurality of time points can be set in the server 200, for example, "10 minutes before the end of the injection", "5 minutes before the end of the injection", "1 minute before the end of the injection", "1 minute before the end of the injection" A notification may be transmitted to be displayed on the terminal 400, such as "end".

Thereby, the information measured by the fluid measuring device can be provided to the terminal and the display unit, so there is an effect that can be easily grasped.

Figure 3 is a block diagram showing the components of the fluid measuring device of the Ringer fluid end notification system according to an embodiment of the present invention.

Referring to FIG. 3 , the transfusion measuring device 100 may include a sensor unit 110 , a control unit 120 and a display 130 .

The sensor unit 110 may detect whether or not the Ringer's sap is injected in various ways. For example, it is possible to detect whether or not the Ringer's sap is injected through a weight change using a weight sensor, and another example is the sap using a light source. An optical sensor capable of detecting the injection of sap by receiving a reflection signal of a light source reflected from water droplets may be used.

In addition, by detecting the vibration generated when the Ringer's sap is injected from the infusion needle 23 into the drip chamber 20 and falls on the surface of the Ringer's sap present in the instillation chamber 20, the injection of the infusion is detected. You may.

The control unit 120 is connected to the sensor unit 110 and receives injection detection information from the sensor unit 110 to determine the remaining injection time and normal injection.

The remaining injection time may be derived from the controller 120 according to the following process.

First, the Ringer's sap injected into the instillation chamber 20 may fall in the form of water droplets, and the Ringer's sap in the form of one droplet may have a uniform volume.

Information about the volume of Ringer's sap input in advance by the server 200 may be transmitted to the control unit 120, and the control unit 120 determines the falling frequency per predetermined time of the Ringer's sap droplets detected through the sensor unit 110. can figure it out

By multiplying the falling frequency of Ringer's sap droplets per unit time by the volume per Ringer's sap droplet, the volume of sap droplets falling per unit time can be derived.

Therefore, by dividing the initial volume of Ringer's sap by the number of drops of sap falling per unit time, the remaining time until the end can be determined.

For example, when 1L of Ringer's sap is injected into a patient, the process of deriving the remaining time in the control unit 120 is as follows.

The dripping frequency of Ringer's sap can be measured in gtt units, where gtt refers to the number of drops falling per minute.

If one droplet is assumed to be 0.067ml and injected at 14gtt,

With 0.067ml x 14/min = 0.938ml/min,

0.938 ml of Ringer's sap can be infused per minute.

If injected at a constant rate of 14gtt, the remaining time until completion is

0.938ml/분

1066분 (약 17.7시간) 이다.1000ml

0.938ml/min

1066 minutes (approximately 17.7 hours).

During the injection, the injection speed can be changed as much as necessary, and the control unit 120 can also determine the remaining time that varies according to the changing injection speed in real time.

The remaining time can determine the remaining capacity except for the amount of Ringer's sap already injected in the initial capacity, and can be calculated according to the same formula as in the above process from the remaining capacity to derive the remaining time to be changed.

Thus, there is an effect of easily grasping the remaining time through the sensor unit and the control unit.

Whether or not the injection is normal can be determined through whether a weight change is sensed through the sensor unit 110 or whether a water droplet is falling.

The display 130 is connected to the control unit 120 and receives information from the control unit 120 to display the Ringer's fluid injection rate, remaining amount and remaining time, and may be provided outside the fluid measuring device 100.

In addition, fluid measuring device 100 may include a fixing clip (150).

The fixing clip 150 may be made in the form of a clip that allows the fluid measuring device 100 to be fixed to the cradle 60.

Figure 4a, 4b is a perspective view and cross-sectional view of a state in which the infusion measuring device is installed in the Ringer infusion device.

Referring to FIGS. 4A and 4B , the sensor unit 110 may include a light emitting unit 111 and a light receiving unit 112 .

The light emitting unit 111 may be provided outside the drip chamber 20 to emit light.

The emitted light may be light of various wavelengths, but is preferably infrared light having a wavelength of 700 nm to 1 mm, which is less affected by a light source such as a fluorescent lamp or sunlight existing inside a hospital room.

The light receiving unit 112 may be provided at a position facing the light emitting unit 111 outside the drip chamber 20 to detect light emitted from the light emitting unit 111 .

When the Ringer's solution does not exist between the light emitting unit 111 and the light receiving unit 112 in the instillation chamber 20 , light emitted from the light emitting unit 111 may reach the light receiving unit 112 as it is.

However, when Ringer's sap exists between the light emitting unit 111 and the light receiving unit 112, that is, the Ringer's sap droplet injected through the inlet 21 of the drip chamber 20 is injected into the light emitting unit 111 and the light receiving unit 112. At the moment of passing between the light emitted from the light emitting unit 111 may not pass through the droplets of Ringer's sap and consequently may not reach the light receiving unit 112.

The control unit 120 may determine that the drops of Ringer's sap have fallen into the drip chamber 20 from the fact that light is cut off from the light receiving unit 112 for a certain period of time.

This has the effect of detecting whether or not the injection of Ringer's sap and the frequency of injection are possible.

5a and 5b are perspective and cross-sectional views of a state in which two pairs of light emitting units and light receiving units are installed in the transfusion measuring device.

5a and 5b, the sensor unit 110 of the Ringer's infusion termination notification system according to an embodiment of the present invention may include two or more light emitting units 111 and a light receiving unit 112.

The sensor unit 110 including the light emitting unit 111 and the light receiving unit 112 has an effect of detecting whether or not the Ringer's sap is injected and the injection frequency is as described above in the description of FIGS. 4a and 4b.

However, this is an effect that can be exerted in general cases and cannot be applied until special cases.

The sensor unit 110 including only a pair of the light emitting unit 111 and the light receiving unit 112 is configured to pass from the upper side to the lower side or to the lower side as long as a droplet of Ringer's sap passes between the light emitting unit 111 and the light receiving unit 112. whether it passes upwards from the , its direction is undetectable.

Therefore, even if the Ringer's sap falls from the lower side of the drip chamber 20 to the upper side in a state where the Ringer's sap container 10 is upside down for reasons such as the fall of the cradle 60 holding the Ringer's sap container 10, one pair The sensor unit 110 consisting of only the light emitting unit 111 and the light receiving unit 112 of the sensor unit 110 can be detected as being normally injected, which causes a problem.

Accordingly, the sensor unit 110 of the Ringer's infusion termination notification system according to an embodiment of the present invention may be provided outside the drip chamber 20 by a predetermined distance in the vertical direction as shown in Figs. 5a and 5b. Since the light emitting unit 111 and the light receiving unit 112 may be included, it is possible to more accurately detect whether or not injection is normal by considering the falling direction.

When the control unit 120 detects that the Ringer's sap is falling from the lower side to the upper side through the sensor unit 110, the corresponding information is transmitted to the server 200, and the server 200 displays the corresponding information on the display unit 300. and display a notification on the terminal 400 so that prompt action can be taken.

This has the effect of more accurately detecting whether or not the injection of Ringer's sap and enabling rapid response.

6 is a perspective view of a state in which a semi-automatic injection amount controller is installed in the fluid measuring device, and FIGS. 7a and 7b are cross-sectional views showing a state in which the cam of the semi-automatic injection amount controller installed in the fluid measuring device does not press and presses the injection tube.

Referring to Figures 6 and 7a, 7b, the Ringer's fluid end notification system may further include a semi-automatic injection amount controller 140.

The injection amount semi-automatic controller 140 can adjust the injection amount of Ringer's fluid injected per unit time and may be installed in the fluid measuring device 100.

The infusion rate is defined as the amount of Ringer's solution injected per unit time.

Unlike the manual injection amount controller 40, which is operated manually, injection rate information can be input and the injection rate can be controlled semi-automatically.

The semi-automatic injection amount controller 140 may include a cam 141 and a cam control unit 142 .

The cams 141 may be provided in pairs on both sides of the injection pipe 30, and each cam 141 rotates the injection pipe 30 on both sides according to the force transmitted by the rotation axis of the motor (not shown). It can be compressed, and the injection speed of the Ringer's solution injected through the injection tube 30 can be adjusted according to the degree of pressure on the injection tube 30.

As the cam 141 rotates toward the inside of the infusion tube 30 and presses it, the injection speed of the Ringer's sap can be slowed down.

The cam control unit 142 may be provided on an outer surface of the transfusion measuring device 100, and injection speed information may be input to adjust the degree of rotation of the cam 141.

The cam control unit 142 may include an acceleration button 142a and a deceleration button 142b.

Acceleration button (142a) is a button that can speed up the injection of Ringer's sap.

Deceleration button (142b) is a button that can slow down the injection rate of Ringer's sap.

The degree of rotation of the cam 141 can be adjusted through the acceleration button 142a and the deceleration button 142b, so that the injection speed can be adjusted.

Depending on the degree of adjustment, the injection speed and remaining time can be displayed on the display 130 in real time, so that the control can be performed while checking the information displayed on the display 130.

In addition, the cam control unit 142 can be connected to the control unit 120, so that the injection speed can be adjusted by the terminal 400 connected to the server 200.

When injection speed control information is input through an application or web page installed in the terminal 400, the corresponding information can be transmitted from the terminal 400 to the controller 120 via the server 200, and the controller 120 inputs According to the obtained information, the injection speed may be adjusted by enabling the cam control unit 142 to adjust the degree of rotation of the cam 141.

Accordingly, the injection speed can be changed while quantitatively checking the injection speed and the remaining time, and the injection amount of Ringer's sap can be adjusted remotely through the terminal 400.

In addition, the Ringer fluid end notification system may further include a reader (not shown).

The reader (not shown) may receive barcode information and transmit the input information to the control unit 120 in a wireless communication method.

The reader (not shown) may input information about the patient's information and Ringer's fluid to be injected into the patient in the form of a barcode.

The controller 120 may receive patient information and information about Ringer's fluid to be injected into the patient from a reader (not shown) and transmit the received information to the server 200 .

In the server 200 , prescription information of a corresponding patient prescribed by a doctor may be input in advance.

The server 200 compares the pre-entered prescription information with the patient information transmitted from the control unit 120 and the information on the Ringer's solution to be injected into the patient, and if the patient's information or the information on the Ringer's solution to be injected do not match, Through the control unit 120, the cam 141 can be rotated to the inside of the infusion tube 30 as much as possible so that the Ringer's solution is not injected.

In addition, the server 200 can display that the information does not match on the display unit 300, the display 130, and the terminal 400.

This has the effect of preventing the patient from being injected into a patient who does not need Ringer's sap or the patient's prescription and other Ringer's sap from being injected into the patient.

8 is a perspective view showing a state in which the Ringer's infusion termination notification system according to an embodiment of the present invention further includes a color change detection sensor.

Referring to FIG. 8 , the Ringer's infusion termination notification system according to an embodiment of the present invention may further include a color change detection sensor 70 .

The color change detection sensor 70 is a sensor capable of detecting a change in color, and can detect a color change by using the principle that the reflectance of the emitted light varies according to the color, and the injection tube connected to the Ringer needle 50 It may be provided at the inlet of (30).

When the blood pressure is higher than the pressure of injecting Ringer's sap, blood may reflux through the Ringer's needle 50.

If the blood pressure is higher than the pressure at which the Ringer's sap is injected, it may be the case where the Ringer's needle 50 is positioned higher than the Ringer's sap container 10 or the patient's blood pressure is high even though it is not positioned on the upper side.

Even if the blood flows back, the patient does not experience pain, so the state of backflow cannot be recognized until the patient visually checks it.

In order to solve this, a color change detection sensor 70 may be provided in the injection tube 30 connected to the Ringer needle 50.

Normally, only colorless and transparent Ringer's sap passes through the infusion tube 30, but at the time when blood starts to flow backward, it rapidly changes from colorless and transparent to red, so that the color change detection sensor 70 can detect it. .

When the color change detection sensor 70 detects the backflow of blood, the control unit 120 transmits it to the server 200 to display whether or not there is a backflow of blood on the display unit 300, and transmits a notification to the terminal 400. Thus, there is an effect of promptly detecting and notifying the backflow of blood.

9 is an exemplary diagram in which Ringer's fluid measurement information is displayed on a terminal of the Ringer's fluid end notification system according to an embodiment of the present invention.

Referring to FIG. 9 , by using an application installed in the terminal 400 or accessing a web page, information such as the patient's personal information, the rate of IV infusion, the remaining amount, and the remaining time can be provided, and the liquid crystal of the terminal 400 can be provided. can be displayed on

In addition to the information displayed on the liquid crystal of the terminal 400, a message informing of the imminent end of Ringer's solution, a message informing of discrepancy when the barcode of the Ringer's solution prescribed to the patient and another Ringer's solution is read by a reader (not shown), a message informing of blood reflux A message indicating that the injection of Ringer's fluid is detected abnormally in the fluid measuring device 100 is not always displayed and may be displayed on the liquid crystal of the terminal 400 in the form of a pop-up window.

Accordingly, there is an effect that medical staff including nurses can monitor the patient without going directly to the patient.

10 is an exemplary diagram in which Ringer's fluid measurement information is displayed on the display unit of the Ringer's fluid end notification system according to an embodiment of the present invention.

Referring to FIG. 10 , the display unit 300 may display information having the same content as that displayed on the terminal 400 .
