Description

Medical infusion signal indicator

This utility model relates to medical monitoring device, relates in particular to a kind of medical infusion indicator.

The medical infusion indicator is used for the monitoring to transfusion patient of ward and family, and when the liquid in the infusion bottle nearly used up, this alarm function in time sent warning signal, thereby reminds patient or the timely fluid infusion of nursing staff or stop transfusion.

The 560 type transfusion devices of producing as American I VAC company are a kind of device that can monitor the transfusion situation automatically, though its automaticity is very high, function is more, but because it is bulky, fetch long price and need be equipped with the special drip stand of a cover when using, infusion bottle and transfusion catheter and monitoring probe, so in fact be difficult to generally promote, especially be not suitable for being used as in numerous middle and small hospitals and the family conventional infusion set.At above-mentioned situation, domesticly also once manufactured experimently a kind of infusion alarm that is easy to popularize, it utilizes the liquid inductosyn to monitor the position of liquid level in the infusion bottle as probe.But this pick off often has phenomenons such as reporting by mistake or fails to report to take place, so be difficult to be put to practicality for a long time always with respect to the liquid reactions rather unstable of different electrolyte concentrations.

The purpose of this utility model is to provide a kind of medical infusion indicator of responding to sensitivity, dependable performance, reporting to the police, indicate critical liquid level automatically.

Another purpose of the present utility model be to provide a kind of structure small and exquisite, cheap, can be in conjunction with the medical infusion indicator that utilizes ready-made drip stand, infusion bottle and transfusion catheter to infuse and guard.

To achieve these goals, medical infusion indicator of the present utility model comprises body and in order to the bottle supporting frame of holding infusion bottle, described bottle supporting frame is arranged on the top of described body, the bottle supporting ring that described body comprises the warning circuit of the portion of setting within it and is arranged on its bottom, described bottle supporting ring and described bottle supporting chord position are in same axial, and be provided with respectively on the two pairs of side positions in the inboard of described bottle supporting ring and be connected with described warning circuit, in order to the infrared emission component of the emission of the liquid levels in described infusion bottle infrared light with in order to receive from the infrared receiver component of the refractive described infrared light of described liquid level that drops to predetermined altitude.

Medical infusion indicator according to this utility model design, because small and exquisite, the simple structure of its volume, and can utilize apparatuses such as existing drip stand, infusion bottle and transfusion catheter to be used, so cost is low, use flexibly, is not only applicable to hospital, medical station, is suitable for patient yet and uses at home.In addition, according to the medical infusion indicator of this utility model design,, use so be suitable for the infusion bottle of various capacity because of its body and the moulding of bottle supporting frame employing particular structure; And, in order to the infrared emission of surveying liquid level critical localisation in the infusion bottle and the bottom that receiving element is arranged on body, and utilize the liquid level in the infusion bottle to transmit signal, thereby make medical infusion indicator of the present utility model have point-device warning function.

Below in conjunction with drawings and Examples medical infusion indicator of the present utility model is described in further detail.
