Description

Description RINGER INJECTION SAFETY SYSTEM
Technical Field
[1] The present invention relates to a ringer injection safety system which enables the residual amount of a ringer's solution in the ringer being administered to be sensed when an patient is hospitalized so as to provide safety to the patient and comfort to the patient's guardian to safely administer the injection solution to the patient, such that both the patient and his or her guardian can easily stay in the hospital without the necessity of paying attention to the administration of the ringer's solution. Background Art
[2] In general, if a patient is hospitalized, he or she typically is given an injection by a nurse. The patient receives an injection of ringer's solution, starting from the first day when the patient stays in the hospital to the day when he or she is discharged from the hospital.
[3] However, the reception by the patient of the injection of the ringer's solution makes him or her nervous as well as must always be checked by the patient or his/her guardian. At present, when the residual amount of the ringer's solution becomes empty nearly, the patient typically calls a nurse with a telephone installed in the sickroom or visits the nurse station to inform a nurse of it.
[4] In addition, if the patient or his/her guardian does not see the moment when the ringer's solution becomes empty while paying attention to other works, there may occur a risk that air is introduced into a ringer's injection tube through which the ringer's solution flows. If such an emergent situation is extended, blood in the patient's body flows backward so as to flow into the ringer's injection tube.
[5] As such, when air flows into the ringer's injection tube, a nurse suffers from much inconvenience when replacing the ringer injection bottle used with a new one, which gives a harm to the patient. Further, when the blood of the patient flows backward so as to be introduced into the ringer's injection tube, air flows into the ringer's injection tube, which makes it impossible for the backward flowed blood to re-flow into the patient's body.
[6] There are a few possibilities that such a phenomenon occurs during the day, but there is a frequent possibility that it occurs during the night since both the patient and his/her guardian sleeps at night. In order to prevent this situation, the patient's guardian must wake up many times to check the residual amount of the ringer's fluid. However, this causes other anguish to both the patient who is afflicted with disease and his/her guardian. [7] In an effort to address and solve such a problem, various techniques associated with the administration of ringer' solution has been developed, but conventional apparatuses for administration of ringer's solution is impractical and is cost- ineffective. Disclosure of Invention
Technical Problem
[8] Accordingly, the present invention has been made in view of the above problems occurring in the prior art, and it is an object of the present invention to provide a ringer injection safety system which resolves another anguish caused to both the patient who is afflicted with disease and his/her guardian such that they can more comfortably or safely stay in the hospital without the necessity of paying attention to the administration of the ringer's solution. Technical Solution
[9] To accomplish the above object, according to the present invention, there is provided a ringer injection safety system. A ringer injection safety system including: a ringer's solution pressure-recognizing section includes a sensor having a piezoelectric element built therein to sense the internal pressure of the ringer injection pack or the ringer injection bottle to output a sensed signal indicative of the sensed internal pressure, and a warning signal generator for receiving the sensed signal from the sensor and generating a warning signal if the sensed pressure is less than a predetermined threshold pressure based on the sensed signal; a transmission section for converting a numerical value corresponding to the warning signal generated from the warning signal generator into an electrical or radio wave signal and outputting the converted electrical or radio wave signal; a reception section for receiving the electrical or radio wave signal from the transmission section; and a display section for receiving the signal from the reception section to display a numerical value corresponding to the received signal.
[10] Preferably, the piezoelectric element may be inserted into or detached from the ringer's injection tube, and is plated with gold or silver that is not harmful to the human body and does not chemically react with the ringer's solution(fluid) contained in the ringer injection pack or the ringer injection bottle.
[11] Preferably, the transmission section and the reception section may wirelessly or wiredly transmit and receive the warning signal generated from the warning signal generator of the ringer's solution pressure-recognizing section, respectively, by means of a wireless sensor mode or a wired sensor mode.
[12] Preferably, the display section may be configured in the form of an alarm device for emitting the sound of at least one of beep, melody, voice, a flash of an LED indicator lamp. [13] Also preferably, the reception section may include a three-stage switch consisting of a left ON-switch, a middle OFF-switch and a right ON-switch so as to enable the operation of the display section connected thereto to be controlled, and wherein the left On- switch of the three- stage switch serves to allow the display sections installed in both a patient's sickroom and a nurse station to be all operated when being depressed and the right ON-switch of the three- stage switch serves to only allow the display section installed in the nurse station to be operated when being depressed.

[28] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[29] FIG. 3 is a conceptual block diagram illustrating the construction of a ringer injection safety system according to a preferred embodiment of the present invention.
[30] The ringer injection safety system according to the present invention includes a ringer's solution pressure-recognizing section 10 consisting of a sensor 12 fittingly mounted in a ringer injection pack or a ringer injection bottle for sensing the internal pressure of the ringer injection pack or the ringer injection bottle depending on the residual amount of a ringer's solution contained in the ringer injection pack or the ringer injection bottle or whether or not the residual ringer's solution exists at a position where the sensor is installed in the ringer injection pack or the ringer injection bottle and a warning signal generator 14 for generating a warning signal depending on a sensed result of the sensor 12, a transmission section 20 for converting a numerical value corresponding to the warning signal generated from the warning signal generator 14 into an electrical or radio wave signal and outputting the converted electrical or radio wave signal, a reception section 30 for receiving the electrical or radio wave signal from the transmission section 20, and a display section 40 for receiving the signal from the reception section 30 to display a numerical value corresponding to the received signal.
[31] FIG. 4 is a diagrammatic view illustrating a ringer injection safety system according to a preferred embodiment of the present invention applied to a ringer injection pack, and FIG. 5 is a diagrammatic view illustrating a ringer injection safety system according to a preferred embodiment of the present invention applied to a ringer injection bottle.
[32] As shown in FIGs. 4 and 5, there is shown a method in which the conventional intravenous infusion set 1 of FIG. 1 or FIG. 2 and the ringer injection safety system 2 of FIG. 3 are manufactured separately such that they are used along with the ringer injection tube upon the insertion of the ringer's injection tube into the ringer injection pack or the ringer injection bottle.
[33] FIG. 6 is a diagrammatic view illustrating a ringer injection safety system according to a preferred embodiment of the present invention which is incorporated into the conventional intravenous infusion (ringer injection pack) set of FIG. 1, and FIG. 7 is a diagrammatic view illustrating a ringer injection safety system according to a preferred embodiment of the present invention which is incorporated into the conventional intravenous infusion (ringer injection bottle) set of FIG. 2. In FIG. 6 or FIG. 7, there is shown a combination type 3 of ringer injection safety system in which the inventive ringer injection safety system is combined with the conventional intravenous infusion set 1 of FIG. l or FIG. 2.
[34] The ringer's solution pressure-recognizing section 10 includes a sensor 12 and a warning signal generator 14. The sensor 12 has a piezoelectric element built therein to sense the internal pressure of the ringer injection pack or the ringer injection bottle to output a sensed signal indicative of the sensed internal pressure. The warning signal generator 14 receives the sensed signal from the sensor 12 and generates a warning signal if the sensed internal pressure is less than a predetermined threshold pressure based on the sensed signal.
[35] The piezoelectric element may be configured to be inserted into or detached from the ringer's injection tube. Also, the piezoelectric element is preferably plated with the material (gold, silver, etc.) that is not harmful to the human body or a material that does not chemically react with the ringer's solution (fluid) to thereby merely perform a sensing function.
[36] The transmission section 20 and the reception section 30 wirelessly or wiredly transmits and receives the warning signal generated from the warning signal generator 14 of the ringer's solution pressure-recognizing section 10, respectively, by means of a wireless sensor mode or a wired sensor mode.
[37] In addition, the reception section 30 includes a three-stage switch 32 consisting of an ON-switch 34, an OFF-switch 36 and an ON-switch 38. The three-stage switch 32 enables the operation of the display section 40 to be controlled.
[38] When the left On-switch 34 of the three-stage switch 32 is depressed, the display section 40 installed in both a patient's sickroom and a nurse station is all operated. When the right ON-switch 38 of the three-stage switch 32 is depressed, only the display section 40 installed in the nurse station is operated. And when the middle OFF- switch 36 of the three-stage switch 32 is depressed, the display section 40 installed in both the patient's sickroom and the nurse station are not operated.
[39] Therefore, the right ON-switch 38 is maintained depressed at night so as to allow only the display section 40 of the nurse station to be operated. In this case, preferably, the display section 40 of the patient's sickroom is not operated so as to allow the patient and his/her guardian to comfortably sleep.
[40] The display section 40 is provided to both the patient's sickroom and the nurse station. The display section 40 is configured in the form of an alarm device for emitting the sound of beep, melody, voice, etc., in the patient's sickroom, and is configured in the form of an alarm device such as an LED indicator lamp for emitting both the sound of beep, melody, voice, etc., and for indicating the number of each sickroom in the nurse station.
[41] Although the sensor 12 senses that the residual ringer's solution does not exist in the ringer injection pack or the ringer injection bottle and the alarm device of the display 40 is operated, in the case where a patient or his/her guardian (caregiver) shortly naps in his/her seat, a nurse does not hear the indicated content of the sensed LED lamp or an alarm sound while shortly napping in the night shift or pays attention to other works such that she loses the time for the ringer injection pack or bottle used to be replaced with a new one, or the replacement of the ringer injection pack or bottle is delayed due to the distance between the current position of the nurse and the associated sickroom, it is preferably to configure the ringer injection safety system such that the a ringer stopper device (not shown) is operated through the reception of the electrical or radio wave signal indicative of a warning signal from the reception section 30 in order to prevent the introduction of air into the ringer's solution through the ringer's injection tube and the backward flow of the blood of the patient.
[42] The ringer injection safety system according to the present invention as constructed above informs an abnormal situation where air is introduced into the ringer's fluid or the ringer's solution flows into the patient's body and then the blood of the patient re- flows out from the patient's body to the patient/guardian or the nurse through the operation of the display section, and particularly informs such an abnormal situation of the nurse in a wireless or wired mode at night so that the patient or his/her guardian can comfortably and safely sleep.
[43] FIG. 8 is a diagrammatic view illustrating the construction of a sickroom to which a ringer injection safety system according to a preferred embodiment of the present invention is applied, in which the transmission section 20 and the reception section 30 wirelessly or wiredly transmit and receive the warning signal generated from the warning signal generator of the ringer's solution pressure-recognizing section, respectively, by means of a wireless sensor mode or a wired sensor mode.
[44] The wired sensor mode is designed such that the sensor 12 having a piezoelectric element built therein senses the internal pressure of the ringer injection pack or the ringer injection bottle, the warning signal generator 14 generates a warning signal if the sensed internal pressure is less than a predetermined threshold pressure based on a sensed signal from the sensor 12 for application to the transmission section 20, the reception section 30 receives the electrical or radio wave signal from the transmission section 20, and the alarm device of the display section 40 connected with the reception section 30 emits the sound of beep, melody, or voice, an flash of an LED indicator lamp, etc., to call the sickroom or the nurse station. In implementing the wired sensor mode, a conventional wired network may be used which is installed to permit a patient or his/her guardian in the sickroom to inform an emergent situation to the nurse station.
[45] The wired sensor mode is designed such that the ringer's solution pressure- recognizing section 10 applies the warning signal to the transmission section 20, and the reception section 30 receives the electrical or radio wave signal from the transmission section 20 for application to the display section 40 connected with the reception section 30. In this case, for the purpose of smooth signal transmission and reception between the patient's sickroom having the inventive ringer injection safety system installed therein and the nurse station, a wireless antenna sensor 5 may be provided to the sickroom.
[46] FIG. 9 is a diagrammatic view illustrating the construction of a display unit installed in a nurse station to which a ringer injection safety system according to a preferred embodiment of the present invention is applied, in which the electrical or radio wave signal wirelessly or wiredly outputted from the patient sickroom is transmitted to the display section 40 of the nurse station so as to allow the alarm device of the nurse station, i.e., the LED indicator lamp to emit a lamp flash or a sound (beep, melody or voice).
[47] FIG. 10 is a diagrammatic view illustrating the construction of a three-stage switch of a ringer injection safety system according to a preferred embodiment of the present invention.
[48] In FIG. 10, the three-stage switch 32 is additionally included in the reception section 20. When the alarm sounds anytime in the day time or at night despite having an excellent function, damage may be caused to the patient, the guardian and the nurse. Thus, the tree-stage switch 32 is designed to control the operation of the display section 40 in view of the above problem.
[49] When the left On-switch 34 of the three-stage switch 32 is kept depressed during the day, the display section 40 installed in both the patient's sickroom and the nurse station is all operated so as to inform the patient's sickroom and the nurse station of an emergent situation. When the right ON-switch 38 of the three-stage switch 32 is kept depressed at night, the display section 40 installed in the nurse station is operated but the display section 40 is not operated in the patient's sickroom so that the patient and his/her guardian can comfortably sleep.
[50] In other words, the ringer injection safety system according to the present invention is configured such that when the left ON-switch is kept depressed using the three-stage switch in the day time after it has been installed, the sensor 12 senses the internal pressure of the ringer injection pack or the ringer injection bottle or whether or not the residual ringer's solution exists in the ringer injection pack or the ringer injection bottle and the warning signal generator 14 generates a warning signal depending on the sensed result for application to the transmission section 20 which in turn transmits the warning signal in the form of an electrical or radio wave signal to the reception section 30. At this time, the reception section 30 receives the electrical or radio wave signal from the transmission section 20 and transmits it to the display section 40 which in turn informs the received emergent content to the outside by means of the sound (beep, melody or voice) or flash of the LED indicator lamp.
[51] The display section 40 is installed in the patient's sickroom and the nurse station so as to concurrently inform an emergent situation to the patient/guardian and the nurse using the sound (beep, melody or voice) or flash of the LED indicator lamp.
[52] When the right ON-switch 38 of the three-stage switch 32 of FIG. 10 is kept depressed at night, although the sensor senses that the sensed internal pressure of the ringer injection pack or the ringer injection bottle is less than a predetermined threshold pressure, the display section 40 installed in the nurse station is operated but the display section 40 is not operated in the patient's sickroom.
[53] As such, the display section 40 installed in the nurse station is operated at night to emit the flash of the LED indicator lamp or the sound (beep, melody or voice) so that when the ringer's solution is completely injected into the patient's body, the display section 40 informs the nurse of this situation. As a result, although the patient and his/ her guardian sleep deeply, the informed nurse replaces the consumed ringer injection pack or the ringer injection bottle with a new one such that the patient and his/her guardian can sleep sufficiently and all the patients and their guardians can sleep deeply even in case of the patient's sickroom accommodating lots of patients.
[54] While the invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Industrial Applicability [55] As described above, the ringer injection safety system according to the present invention is very useful industrially as it includes a display section for informing the replacement time of the ringer injection pack or bottle depending on a variation in the internal pressure of the ringer injection pack or bottle to the outside.
