  A preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1, 2, and 3, the embodiment of the present invention includes a clamping holder 10, a detection device 20 provided in the clamping holder 10, an alarm device 30 connected to the detection device 20, and A carrier rocking device 40 and the like are included. The holding holder 10 is sandwiched at an appropriate position on the flow rate visible cylinder 52 in the medicine injection device 50, and the flow rate visible cylinder 52 is not deformed by receiving pressure. Generally, the medicine injection device 50 is provided with a medicine container 51, a flow rate visible cylinder 52, a tube 53, a flow rate adjustment controller 54, an injection needle 55, and the like.

  The main body of the holding holder 10 is designed in various ways as needed, and the holding holder 10 is of a type that is inserted or removed from the outside of the flow rate visible cylinder 52, and is easy to operate. Make it reusable. When a spring having an appropriate size and an arc-shaped holding portion are provided on the clip 11 as shown in FIG. 1, the clip 11 is opened and simultaneously fixed to the outside of the flow rate visible cylinder 52. A marking line 13 is provided on the outside of the clip 11 at a horizontal and opposed position between the transmitter 21 and the receiver 22 to provide a simple localization holding position. After the holding, the inside of the flow rate visible cylinder 52 is visually observed. It can be seen how the drug is infused.

  The detecting device 20 is installed at a position where the clips 11 on both sides of the holding holder 10 are opposed to each other, and its detecting function is designed based on the principle of transmitting and receiving general infrared rays. In addition to the infrared rays, it is also possible to use emission and reception of different methods such as a magnetic wave and a laser. The detecting device 20 places the transmitter 21 and the receiver 22 inside the clip 11, respectively, and the transmitter 21 directly radiates the receiver 22 through the transparent flow rate visible cylinder 52. (See FIG. 4). Further, a correlated electronic control line is provided in the alarm device 30 and is controlled by an externally connected switch 31, or data is displayed on a monitor 32, which is used by a user as a reference for operation.

The carrier swinging device 40 is installed below the liquid outlet pipe 521 in the flow rate visible cylinder 52, and there is no particular limitation on the installation method. It is assumed that it is localized. The carrier swinging device 40 is mainly provided with a carrier 41 and a rod structure 42 for causing the carrier 41 to swing. When the medicine drops downward from the liquid outlet pipe 521, one side of the carrier 41. As a result, the carrier 41 shakes due to this principle, and an intermittent blocking effect occurs between the detection devices 20. The structure relationship between the carrier 41 and the Kong structure 42 is designed as required. As shown in FIG. 3, in the present invention, a T-shaped rod 421 extends from below the upper lid 522, and the horizontal rod 422 is The horizontal rod 422 is formed on a left-right symmetric shaft hole 411 provided on the base 41 and serves as a lever shaft when the carrier 41 swings. The carrier 41 is a chip of an appropriate size, swings in the flow rate visible cylinder 52, and the T-shaped rod 421 is not located at the center in the flow rate visible cylinder 52, so that the horizontal rod 422 is The lever to be formed is separated from the center.
In addition, a weight 412 may be provided on one side of the carrier 41, whereby the length of the carrier 41 located on both sides of the horizontal rod 422 is changed, and the balance is maintained in a horizontal state without shaking. A concave groove 413 is provided at the center of the carrier 41 so that the liquid outlet tube 521 has a shape more suitable for receiving the medicine dripping downward. A convex piece 414 is provided on the carrier 41 so that when the carrier 41 swings, it stops on the T-shaped rod 421 so that the swing width of the carrier 41 is too large to be in a vertical state. To In the above-described structure, the lever of the lever structure 42 has the horizontal rod 422 as the pivot. However, the lever is not limited to the horizontal rod 422, but may be designed as having a pivot on both sides. A convex shaft may be provided on each of the two corresponding points on the inner wall, and a carrier corresponding to the shaft frame may be placed on the convex shaft on both sides to form the kong rod structure 42.

At the time of use, as shown in FIGS. 4 and 5, first, when the medicine has not yet dripped from the liquid outlet pipe 521, the carrier 41 is in a horizontal state while maintaining a balance (see FIG. 4). There is no blocking effect between the transmitter 21 and the receiver 22 in the detection device 20. At this time, the electronic control circuit in the alarm device 30 is not yet driven.
The rate of infusion is controlled by the flow control controller 54, which is generally based on the number of drops per minute, for example, six drops per minute or eight drops per minute. Is determined. Therefore, when the drip injection is started, the number of drops of the drug per minute is set by the flow rate controller 54, and then drops below the liquid outlet pipe 521. That is, by hitting the long side of the carrier 41, the long side of the carrier 41 is inclined downward (see FIG. 5).
At this time, the carrier 41 is blocked between the transmitter 21 and the receiver 22, and a frequency such as infrared rays emitted by the transmitter 21 is blocked without being received. In addition, since the drug drips at a stable rate of six drops or eight drops per minute, an appropriate vacant time is created between the drops of the drug one by one, and the carrier 41 receives one drop of the drug and faces downward. After tilting, the dripped drug simultaneously flows downward and leaves the carrier 41, and returns to its original horizontal position when the carrier 41 is not under the force of the drug.

In this way, the state returns to the state in which the transmitter 21 and the receiver 22 are cut off, and the repetition is interrupted at a constant speed with intermittent operation, and the detection device 20 is switched to the open circuit state or the closed circuit state. Become. Also, by installing the electronic control circuit, the number of drops of the medicine in one minute is automatically calculated, or the flow rate and the speed in one minute are calculated. This becomes the set value for detection and is displayed on the monitor 32 of the alarm device 30.
After a certain number of drops and a flow rate per minute are detected and set, and when the number and quantity of the dripping drugs are detected to be abnormal by the detecting device 20, for example, the patient unknowingly detects the tube. Even if the abnormal state continues for a certain period of time due to, for example, pressing the pressure 53, the flow rate controller 54 not working normally, or the time when all the medicines have been used, the normal state is maintained. Otherwise, the electronic control circuit is set so that the alarm device 30 automatically sounds an alarm.

In this manner, the number of drops and the flow rate of the infusion of the present invention are set and detected in one minute, and the amount of the medicine in the medicine container 51 is generally indicated. When the infusion is started, the time at which the infusion ends is predicted in advance, and by inputting the predicted time into the alarm device 30 or displaying the time on the monitor 32, the caregiver can simultaneously provide several caregivers. When performing the infusion, the time when the infusion ends is predicted by the electronic device, which is convenient.
Although the alarm device 30 is connected to the detection device 20, the connection of the lead wire connected therebetween can be set to an appropriate length, which is convenient, and the alarm function of the alarm device 30 is activated by a buzzer or voice. Or LED or flashing lamp, or infrared transmission (IR) or radio transmission (RF), and the alarm signal can be transmitted to other alarms and nurse stations to further improve illness. Nursing efficiency can be improved.
