Embodiment Construction

[0019] Such as figure 1 As shown, an infusion tube liquid level detection and alarm device of the present invention comprises:

[0020] The detection unit used to detect the change of the liquid level in the infusion tube includes a light source 1 and a light receiver 2; the light source 1 is a light emitting diode, usually with a current limiting resistor; the light receiver is a photosensitive receiving tube, usually with a voltage divider resistor. The light source 1 and the light receiver 2 can be placed on both sides of the infusion tube 7, or on the same side. Both the transmitting circuit and the receiving circuit are connected to the power supply.

[0021] The electronic control unit used to receive the liquid level change detected by the detection unit, transmit and send an alarm signal, consists of a sending single-chip microcomputer 14 connected with the optical receiver, a receiving single-chip microcomputer 20 connected with the sending single-chip microcomputer ...

Abstract

The invention discloses an infusion tube liquid level detection alarm device which comprises a detecting unit used for detecting the liquid level change in an infusion tube and composed of a light source and a light receiver, an electric control unit used for receiving the liquid level change detected by the detecting unit and transmitting and sending an alarm signal and formed by electrical connection of a sending single-chip microcomputer connected with the light receiver, a receiving single-chip microcomputer connected with the sending single-chip microcomputer and an alerter, a starting switch and a power supply, and a fixing unit used for fixing the detecting unit, the sending single-chip microcomputer of the electric control unit, the starting switch and the power supply on the portion, between an infusion bottle and a Murphy's dropper, of the infusion tube and composed of a shell body provided with a cover plate, a tube groove formed in the shell body, and a clamping spring placed outside the shell body to lock the cover plate of the shell body, wherein a dark spongy cushion layer used for isolating the portion, inside the shell body, of the infusion tube from an outside light source is further arranged between the cover plate in the shell body and the infusion tube. The infusion tube liquid level detection alarm device is not susceptible to outside light, accurate in alarm giving, highly adaptable to infusion types, convenient and easy to use, and capable of being widely used for medical infusion.

Description

technical field [0001] The invention belongs to the technical field of infusion equipment, in particular to a non-contact infusion tube liquid level detection and alarm device which automatically alarms by detecting the liquid level in the infusion tube. Background technique [0002] At present, when the infusion device in the hospital ward and the infusion hall ends the infusion or changes the infusion bottle, the nurse is generally reminded by calling or manually pressing the alarm after being observed by the accompanying staff or the patient. However, if the accompanying personnel or patients do not pay attention, the medical staff will not know after the infusion, so that the infusion tube will enter air or return blood, resulting in unpredictable consequences. Reduce the mental and physical burden of the accompanying staff or patients. Especially in the infusion process at night, this brought physical and mental devastation to the accompanying staff and patients. For ...
