Description

  The present invention relates to an infusion monitoring device, and more particularly to an infusion monitoring device that is attached to an infusion tube and senses the infusion state of the infusion.

  In order to replenish the patient with nutrients (that is, sucrose) and injection solution necessary for the treatment and management of the patient, the infusion contained in the infusion container (infusion pack, infusion bottle) is injected into the patient's blood vessel.

  As shown in FIG. 1, a general infusion device includes an infusion container 10 that contains an infusion, a tube 40 that is connected to the infusion container 10 and supplies an infusion to the human body, and the tube 40 and the infusion container. 10, a drip tube 20 for storing the infusion solution, a syringe 50 installed at the end of the tube 40 and injected into a blood vessel of the human body, and a tube 50 installed between the drip tube 20 and the syringe 50 to disconnect the tube. It is comprised with the flow volume regulator 30 which adjusts an area and adjusts the quantity which infusion solution flows into a syringe.

  In such an infusion device, there are inconveniences that nurses and nurses have to stay around the patient to check the amount of the infusion to stop the infusion and replace the infusion container. When the removal and replacement timing of the fluid is missed, there is a risk of air flowing along the tube into which the infusion is injected and a risk of being inflowed into the blood vessel. A sensing device to report is required.

  Various infusion monitoring methods have been developed to solve such problems. Conventional infusion monitoring methods can be broadly classified into the following three methods.

  First, there is a device that attaches a light sensor to the stopper of an infusion container or an infusion hose to detect the infusion of the infusion by changing the light sensor's condition, but this is affected by the color and transparency of the infusion, In the case of an infusion with a small change in preparation due to the presence or absence of an infusion, malfunction may occur.

  Second, there is a method that uses the property that an electric current flows between two electrodes only when an electrode is inserted into the infusion container and there is infusion. This method has a problem that it is exposed to contamination by foreign matter and bacteria due to electrodes inserted in the infusion solution, and the device using the weight change of the infusion solution is not only complicated in structure and easy to install and carry, but also in the infusion container. Since the set value differs depending on the weight, there is a problem that it is inconvenient to use.

  Finally, there is Korean Patent Registration No. 10-0802313 as a form that improves the above-mentioned problems. According to this, when the power source is applied to the light emitting unit, the light emitting unit emits light, and the amount of light collected in the light receiving unit changes depending on the presence or absence of the infusion solution.

  However, since the prior patent monitors the infusion of the infusion while the external light is blocked, a separate sealing device such as an opaque box is required to prevent external light from penetrating.

  As described above, there is a possibility that the optical sensor malfunctions due to the influence of natural light or external light (noise) such as indoor lighting, and there is a problem that accuracy is lowered in determining whether or not the infusion can be exhausted. A monitoring device that is not affected by the layout or ambient lighting is required.

The fluoroscopic window 113 is formed so that the drip tube 1 can be directly checked with the naked eye with the main body 110 installed, and a nurse, a doctor, or the patient himself can directly check with the naked eye that the infusion is being injected. When trying to do so, the internal state of the drip tube 1 can be directly confirmed through the transparent window 113.

  The upper opening of the main body 110 is formed so as to correspond to the outer diameter of the upper end of the infusion tube 1, but the inner diameter of the upper opening of the main body 110 is smaller than the outer diameter of the upper end of the infusion tube 1 by a predetermined length. When the main body 110 is installed in the drip tube 1, the upper side opening pressurizes the upper end portion of the drip tube 1 with a predetermined force so that the coupling state is maintained.

  The lower opening of the main body 110 is formed so as to correspond to the outer diameter of the tube through which the infusion solution moves by connecting the infusion tube 1 and the injection portion inserted into the patient's body. A tube fixing part is formed for coupling with the tube.

  The tube fixing portion fixes the main body 110 so as to be tightly fixed to the tube so that the main body 110 can maintain the combined state in a state in which the main body 110 surrounds the drip tube 1. For this, the tube fixing part includes an auxiliary clamping member 115 installed on the lower inner side of the main body 110 and a clamping member 118 connected to the lower outer side of the main body 110.

At this time, when passing between the light emitting unit 132 and the light receiving unit 133, the light emitted from the light emitting unit 132 is received by the light receiving unit 133 due to the infusion. Either light is not received or light distortion occurs. The light receiving unit 133 transmits a light reception signal to the signal determination unit 134, and the signal determination unit 134 determines whether or not the infusion solution has fallen through the light reception signal of the light reception unit 133.

  At this time, the signal discriminating unit 134 also collects light emission signals irradiated with light from the light emitting unit 132 and applies them to signal discrimination. This is to prevent detection errors due to natural light. However, when natural light is incident through the transparent window 113 or the incision 111, the infusion passes while the infusion passes between the light emitting part 132 and the light receiving part 133. Although the light has been dropped, there is a possibility that a sensing error may occur if light is received by the light receiving unit 133 due to the natural light. Therefore, the signal determining unit 134 generates the light emission signal of the light emitting unit 132 and the light reception signal of the light receiving unit 133 Are coincident with each other, it is determined that the signal of the light receiving signal of the light receiving unit 133 is a normal signal, and only when the light receiving signal is not input while the light emitting signal is input, it is determined that the infusion is falling.

  The signal discrimination unit 134 transmits discrimination information to the information processing unit 140.

  The information processing unit 140 analyzes the infusion volume and the infusion rate based on the information received from the optical sensor 130.

  The analysis information of the information processing unit 140 is transmitted to the control unit 150, and the control unit 150 displays the analysis result through the display 112. Since the control unit 150 is connected to the input unit 114, the setting can be initialized or reset, or the display information displayed on the display 112 can be changed.

  The control unit 150 may be connected to a flow rate control unit 160 for controlling the infusion rate of the infusion solution to automatically control the flow rate. The flow rate control unit 160 is installed in the tube, and can control the flow rate in a form that narrows or widens the internal passage of the tube.

  In addition, information processed by the information processing unit 140 through the wireless communication unit 170 can be transferred to the external administrator terminal 180. The wireless communication unit 170 can apply a wireless communication method such as Bluetooth, Wi-Fi, or beacon, and can transmit information to a portable terminal of an administrator, for example, a smartphone, a tablet PC, or a dedicated terminal. The related information can be transmitted to the PC so that the administrator can check the infusion information without going to the patient directly.

  The wireless communication unit 170 may receive a signal from an administrator's terminal, and the administrator may remotely control the flow rate control unit 160 through the signal.
