An automatic sensing and warning device for placing an intravenous drip includes a transmitter unit, a blocking unit, a receiver unit, and a fixing device. The transmitter unit is attachable to an injection site on a patient's hand and is operable to transmit an identification signal. The receiver unit is arranged on the blocking unit and includes a drive circuit and a warning device. The fixing device supports the blocking unit and the receiver unit on the intravenous drip pole. The RF receiver is set at a predetermined vertical distance from a drip chamber and areas above and below the RF receiver are respectively defined as dangerous and safe areas. When the injection site is spaced from the drip chamber by a distance shorter than the predetermined distance, the RF receiver receives the identification signal from the RF transmitter and the drive circuit activates the warning device to issue warnings.

1. An automatic sensing and warning device for placing an intravenous drip, comprising: a transmitter unit, which comprises an encoder circuit and a radio frequency (RF) transmitter that are electrically connected, the encoder circuit comprising a first switch and an encoder integrated circuit (IC)
1. An automatic sensing and warning device for placing an intravenous drip, comprising: a transmitter unit, which comprises an encoder circuit and a radio frequency (RF) transmitter that are electrically connected, the encoder circuit comprising a first switch and an encoder integrated circuit (IC) for setting an identification signal of the transmitter unit, wherein the RF transmitter is operable to transmit out the identification signal and the transmitter unit is adapted to attach to an injection site on a hand of a person;a blocking unit, which comprises a blocking member and a seat, the blocking member being made of a metallic material and mounted on the seat, the seat being adapted to attach to an intravenous drip pole to be substantially perpendicular to the intravenous drip pole, so as to block the identification signal transmitted from the RF transmitter located in one given range of the seat;a receiver unit, which is mounted to the blocking unit, the receiver unit comprising an RF receiver, a decoder circuit, at least one drive circuit, and at least one warning device, the RF receiver being operable to receive the identification signal transmitted from the RF transmitter located in another one given range of the seat, the decoder circuit being coupled to the RF receiver, the drive circuit being coupled to the decoder circuit, the warning device being coupled to the drive circuit, the decoder circuit comprising a second switch and a decoder IC; anda fixing device, which supports the blocking unit and the receiver unit and is adapted to mount to the intravenous drip pole;wherein the blocking member comprises a piece of disk-like tin foil. 2. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the encoder circuit and the RF transmitter of the transmitter unit are mounted on a first circuit board. 3. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the transmitter unit is mounted to a hand ring that is provided with hook and hoop fastening strips in order to allow the hand ring to attach the transmitter unit to the injection site of the hand. 4. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the decoder circuit is coupled to a single-chip, and the single-chip comprises a time delay module for a delay of time in issuing a drive signal to the drive circuit, so as to delay driving the warning device. 5. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the drive circuit comprises a light indication drive circuit and a sound warning drive circuit, the light indication drive circuit being electrically connected to a light emitter, the sound warning drive circuit being electrically connected to a buzzer. 6. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the RF receiver, the decoder circuit, and the drive circuit the receiver unit are mounted on a second circuit board. 7. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the fixing device comprises a C-clip. 8. The automatic sensing and warning device for placing an intravenous drip according to claim 1, wherein the receiver unit comprises a shut-down switch, which is operable to cut off a single transmission circuit of the receiver unit.
