[24] Hereinafter, a preferred embodiment of the invention will be explained in detail with reference to the appended drawings.

[25] FlG. 1 illustrates an intravenous Infusion management apparatus according to an embodiment of the present invention, FlG. 2 illustrates a controller of FlG. 1 in detail, and FlG. 3 is a cross-sectional view of a sensing means illustrated in FlG. 1.

FlG. 7 illustrates a configuration of an intravenous Infusion management apparatus including a multi-control unit according to another embodiment of the present invention, FlG. 8 illustrates a plurality of intravenous infusion management apparatuses including the multi-control unit of FlG. 7 managed by an infusion sensing display unit and a computer, FlG. 9 illustrates a charging system for charging batteries illustrated in FIGS. 1 and 7 according to an embodiment of the present invention, and FlG. 10 illustrates a configuration of an high-efficiency inexpensive intravenous Infusion management apparatus using an accurate intravenous infusion set of a conventional infusion pump system according to an embodiment of the present invention. [26] Referring to FIGS. 1 and 2, an intravenous Infusion management apparatus 100 according to an embodiment of the present invention includes a controller 10 performing a control operation, a sensing means 20 sensing a variation in the level of fluid contained in an intravenous infusion set 1, and a control means 30 for blocking the supply of fluid.

[27] The controller 10 includes a control panel 11 having a low- voltage warning lamp 15 for warning of the change of a battery 40, a sensing lamp 16 for warning of the change of fluid, a power button 17 for deciding the operation of the controller 10, and an alarm-releasing button 18 for canceling the alarm. The sensing means 20 includes a sensor such as a capacitive sensor 22 that generates a predetermined electric signal in response to a variation in the level of fluid contained in the intravenous infusion set 1, which is supplied by free-fall according to the weight of the fluid and gravity. The control means 30 presses a tube 3 connected to the intravenous infusion set 1 in response to a control signal of the controller 10 to block flow of fluid and air.

[28] The battery 40 is located on the flat top of the controller 10 and inserted into a top connecting groove 13b in which a power supply terminal 13c is formed, which is formed on the top of the controller 10, in a sliding manner to be combined with the controller 10. The controller 10 further includes a side connecting groove 13a used to hang the controller 10 on a hanger 4 and a return button 32 for returning the operation of the control means 30 to the original state. The side connecting groove 13a and the return button 30 are formed on the side of the controller 10. Furthermore, the controller 10 includes an alarm output part 14 for outputting the alarm, which is formed at the lower part of the front side of the controller 10.

[29] The controller 10 includes a PCB inside. The PCB compares a signal input to each sensor, which will be explained later, with a predetermined reference value, turns on/ off the warning lamp and the sensing lamp and sounds the alarm. The PCB includes an MPU and a memory. A circuit on the PCB can be easily constructed according to a well-known technique so that a detailed explanation thereof is omitted.

[30] The power supply terminal 13c set in the top connecting groove 13b receives the voltage externally charged in the battery 40 and transmits the voltage to the controller 10. An additional connecting groove cover 12 is provided in order to prevent the side connecting groove 13a and the top connecting groove 13b from being damaged when not used.

[31] The low- voltage warning lamp 15 is turned on in order to warn of the change of the battery 40 when the voltage charged in the battery 40 is lower than an available voltage. The sensing lamp 16 is turned on in order to indicate the change of a ringer bottle 2 or pack when the level of fluid contained in the intravenous infusion set 1, sensed by the capacitive sensor 22 set in the sensing means 20, is lower than a pre- determined level.

[32] The power button 17 controls the operation of the controller 10 and the alarm- releasing button 18 stops the alarm output through the alarm output part 14.

[33] The sensing means 20 is configured of a conventional sensor that generates a predetermined electric signal in response to the quantity of dropping fluid. In the present embodiment, the capacitive sensor 22 senses a variation in the level of fluid contained in the intravenous infusion set 1, converts the sensed value into an electric signal and transmits the electric signal to the controller 10 to indicate a fluid change time.

[34] That is, the intravenous infusion set 1 maintains a uniform fluid level all the time according to the fluid supplied from the ringer bottle 2, and thus the fluid level of the intravenous infusion set 1 is lowered when the supply of fluid from the ringer bottle 2 is reduced. By using this fact, the present invention proposes a simple and sure method that measures the fluid level of the intravenous infusion set 1 to judge the fluid change time.

[35] Referring to FlG. 3, the sensing means 20 includes an insertion hole 21 and the capacitive sensor 22 formed at one side of the insertion hole 21. The intravenous infusion set 1 is pushed and inserted into the insertion hole 21 to be set in the sensing means 20 in close proximity to the capacitive sensor 22.

[36] The capacitive sensor 22 generates an electric signal using an electrical characteristic variation according to the dielectric constant of an object. The present invention constructs the intravenous Infusion management apparatus 100 in such a manner that a reference value based on a predetermined fluid level is set and stored in a memory (not shown) included in the controller 10 and the controller 10 warns of the fluid change time when the electric signal transmitted from the capacitive sensor 22 becomes lower than the reference value.

[37] The control means 30 is located at the lower part of the right side of the controller

10 and presses the tube 3 connected to the intravenous infusion set 1 in response to the control signal of the controller 10 to block or control flow of the fluid and air.

[38] Referring to FIGS. 4 and 5, in the control means 30, the return button 32 and a semicircular blocking protrusion 38 are connected by a moving axis 31 that penetrates a housing 37 including a spring 33 and a retaining groove 36 for fixing a retaining member 35 operating by a solenoid is formed at one side of the moving axis 31.

[39] When the sensing means 20 senses the fluid change time, the controller 10 generates a control signal to operate the solenoid 34. Then, the retaining member 35 is turned upward by the solenoid 34, and thus the moving axis 31 and the blocking protrusion 38 are moved to the left according to the restoring force of the spring 33. As a result, the blocking protrusion 38 presses the tube 3 to block flow of the fluid and air.

[40] When the ringer bottle 2 is replaced with a new one and supply of the fluid is resumed, the return button 32 is pushed. Then, the moving axis 31 is moved to the right to press the spring 33 and the retaining member 35 is turned downward to be caught by the retaining groove 36. Accordingly, the pressure put on the tube 3 by the blocking protrusion 38 is canceled. At this time, the retaining member 35 is freely turned on a hinge so that it is normally tilted downward by gravity and inserted into the retaining groove 36. When the solenoid 34 is operated, the retaining member 35 is instantaneously lifted upward to come out off the retaining groove 36 by the restoring force of the spring 33.

[41] According to another embodiment of the present invention, an additional infusion sensing display unit 60 installed in a nurse station manages a plurality of intravenous infusion management apparatuses 100.

[42] Referring to FlG. 6, the infusion sensing display unit 60 includes a receiving antenna 61 for receiving a radio signal, number pads 62 for visually identifying controllers of the plurality of intravenous infusion management apparatuses, identification lamps 63 for indicating controllers 10 transmitting a fluid change signal, a speaker 64 sounding the alarm and an alarm lamp 65 flicking when the fluid change signal is received, and an alarm button 66 for stopping or resuming the generation of the alarm.

[43] That is, a radio transmitter (not shown) is set in the controller 10, the radio transmitter wirelessly transmits a unique IP signal corresponding to each controller 10 and the fluid change signal, and the infusion sensing display unit 60 indicates the signal transmitted from the radio transmitter such that a nurse can recognize the controller transmitting the signal. Accordingly, the fluid change time for a lot of patients can be clearly managed.

[44] The method of identifying a plurality of controllers in response to their unique IP signals employs the technical contents of Korean Utility No. 302728 entitled ASK wireless calling bell using saw resonator , applied by the present applicant, so that detailed explanation thereof is omitted.

[45] An intravenous Infusion management apparatus capable of simultaneously blocking the supply of fluid and controlling the supply of fluid by improving the controller 10, the sensing means 20 and the control means 30 according to another embodiment of the present invention is illustrated in FIGS. 7 and 8.

[46] Referring to FlG. 7, the intravenous Infusion management apparatus according to another embodiment of the present invention is constructed by adding an additional multi-control unit 50 for controlling a fixed quantity of fluid, a supporting unit 55 and a supporting axis 54 for supporting a ringer bottle 2 or pack, and a setting bar 53 for vertically moving or rotating the intravenous Infusion management apparatus on the basis of the hanger 4 to the intravenous Infusion management apparatus 100 illustrated in FTG. 1.

[47] The multi-control unit 50 includes a plurality of control buttons (not shown) for controlling functions of the controller 10 and an LCD(Liquid Crystal Display) (not shown) for visually displaying the quantity of infusion and other related data values. Furthermore, the multi-control unit 50 can include the function buttons and the indication lamps of the controller 10 in order to directly control the sensing means 20 and the control means 30.

[48] In addition, the multi-control unit 50 includes a battery 40 attached to the side thereof to supply power, a transmission antenna 51 located at the upper part of the right side of the multi-control unit 50 to transmit a radio signal, and an additional emergency call button 52 attached to the lower part of the right side of the multi-control unit 50 to call a nurse in an emergency.

[49] The supporting unit 55 includes a rotary movement preventing member 56 in order to stably support ringer bottles or packs of various sizes and is connected to the bar 53 through the supporting axis 54. The supporting unit 55 includes a capacitive sensor 22 set in close proximity to the ringer bottle 2 to sense the quantity of fluid left in the ringer bottle and transmit the sensed value to the multi-control unit 50 through a cable 57.

[50] The sensing means 20 includes an ultrasonic sensor 23 instead of the capacitive sensor to sense the quantity of fluid dropping into the intravenous infusion set 1 from the ringer bottle 2 in real time and transmit the sensed value to the multi-control unit 50 through the cable 57.

[51] That is, the multi-control unit 50 judges the fluid change time based on an electric signal transmitted from the capacitive sensor of the supporting unit 55 and judges the supply of fluid from an electric signal transmitted from the ultrasonic sensor 23 of the sensing means 20. Accordingly, at the fluid change time, the multi-control unit 50 generates a predetermined control signal and transmits the control signal to the controller 10. Then, the controller 10 operates the control means 30 to block or control the supply of fluid. Here, the fluid is blocked according to the operation of the control means 30 illustrated in FIGS. 4 and 5.

[52] When the quantity of fluid dropping is controlled, a nurse operates a fluid control knob (not shown) set on the tube 3 while visually confirming data values displayed on the LCD of the multi-control unit 50 to maintain a fixed quantity of fluid.

[53] Another embodiment of the present invention improves the control means 30 to automatically control the supply of fluid instead of using the fluid control knob that manually controls the supply of fluid. Specifically, the degree to which the blocking protrusion 38 of the control means 30 is moved to the left (the degree to which the tube is pressed) is finely adjusted (that is, the quantity of movement of the blocking protrusion is controlled) to automatically control the supply of fluid.

[54] A structure for controlling the quantity of movement of the blocking protrusion 38 can be easily constructed through a conventional method using a gear so that a detailed explanation thereof is omitted. The multi-control unit 50 feedback-controls the degree to which the blocking protrusion 38 is moved in response to a variation in a signal value sensed by the ultrasonic sensor 23 to enable infusion of a fixed quantity of fluid.

[55] The setting bar 53 is detachably fixed to a vertical axis of the hanger 4 using a fixing member such as a screw and constructed such that it can be vertically moved or rotated according to the environment where the intravenous Infusion management apparatus is used.

[56] The infusion sensing display unit 60 installed in the nurse station has the same configuration as the infusion sensing display unit 60 illustrated in FlG. 6. Here, the infusion sensing display unit 60 can be connected to an additional computer 70 in order to store and control the infusion management state of the intravenous Infusion management apparatus 100.

[57] FlG. 9 illustrates a charging unit 80 for simultaneously charging the batteries 40 attached to the controller 10 and the multi-control unit 50 according to an embodiment of the present invention. The charging unit 80 can simultaneously charge the multiple batteries 40 and turns on a charging completion lamp 81 when each battery 40 has been charged. The charging unit 80 employs a conventional charging unit so that a detailed explanation thereof is omitted.

[58] The present invention can be applied to a conventional infusion related system or the infusion related system from which a part of its functions is removed. Referring to FlG. 10, a mechanical forced infusion part (not shown) is eliminated from a conventional infusion pump system and only an accurate intravenous infusion set 90 for accurately controlling the quantity of fluid according to the present invention is applied to the infusion pump system.

[59] That is, while the conventional infusion pump system forcibly infuses a fluid in a mechanical manner (motor and finger), the present invention changes the infusion manner to the free-fall manner according to the weight of the fluid and gravity and attaches the accurate intravenous infusion set 90 to the bottom end of the conventional infusion pump system. Accordingly, the mechanical forced infusion part that is an expensive component in the conventional infusion pump system is not used so that the manufacturing cost of the entire system can be remarkably reduced. Furthermore, the accurate intravenous infusion set 90 is added to the conventional infusion pump system to improve the reliability of the system.

[60] Furthermore, the conventional infusion pump system includes a sensor for sensing air in a fluid tube and, when the sensor is not operated, air is forcibly infused into the blood vessel of a patient. However, the present invention overcomes this problem by infusing a fluid in the free-fall manner. That is, air cannot be infused into a blood vessel because of blood pressure in the blood vessel in the free-fall state even when the air sensor is not operated.

[61] Moreover, the present invention allows a medical team to correctly aware of the current infusion state through the LCD 19 to rapidly cope with an emergency.

[62] Furthermore, the present invention can realize a reliable safety apparatus that judges whether a fluid is left using the capacitive sensor 22 for sensing the level of remaining fluid and the ultrasonic sensor 23 for sensing the fluid dropping from the ringer bottle 2 and forcibly blocks the infusion of fluid through the control means 30 when the fluid is not sensed.

[63] Accordingly, if the accurate intravenous infusion set of the infusion pump system is used for the present invention, the intravenous Infusion management apparatus of the present invention can perfectly replace a conventional expensive infusion pump system at a low cost while including most of the functions of the conventional infusion pump system. In addition, the infusion state can be remotely monitored in real time using a radio transmitting and receiving system. Industrial Applicability

[64] The intravenous Infusion management apparatus 100 according to the present invention can secure stability, compatibility and mobility by using the existing intravenous infusion set, ringer bottle or pack and hanger and using free-fall according to the weight of a fluid and gravity, perfectly block air and prevent a patient s blood from flowing backward.

[65] Furthermore, the present invention automatically informs a medical team of the completion of fluid infusion such that a patient or his/her guardian needs not observe the fluid infusing state.

[66] Moreover, a radio transmitter is included in the controller 10 and the infusion sensing display unit 60 including a radio receiver is installed in a nurse station to allow a nurse to recognize and cope with the operating state of the intravenous Infusion management apparatus 100 installed in a ward in real time. This minimizes man power for maintenance and reduces economical cost.

[67] In addition, the multi-control unit 50 feedback-controls the control degree of the control means 30 to supply a fixed quantity of fluid all the time according to the ultrasonic sensor 23 of the sensing means 20 and the capacitive sensor 22 of the supporting unit 55, thereby improving the reliability of the infusion management apparatus.
