Transfusion warning device

Abstract

The infusion alarm includes a tablet-type buzzer equipped with a drive circuit board, characterized in that: the tablet-type buzzer and the drive circuit board are installed in a groove at the front end of an elastic body, and the elastic body It is a case; the end of the case is provided with a film, the film is concave, and the outside of the film is provided with a glue layer; the bottom of the groove is located on the inner side of the case, and a guide point communicating with the drive circuit board is provided, corresponding to the guide point. The film is located on the inner side of the cover body and has a contact point communicating with the drive circuit board; on the side of the cover body, there is a metal edge, and an independent metal sheet corresponding to the metal edge can be fixed on the infusion bag. The invention has the advantages of low cost, convenient use and installation, stable use effect and no restriction on use conditions.

Description

technical field [0001] The invention relates to an infusion alarm, which belongs to the technical field of A61M of IPC classification. Background technique [0002] Infusion, also known as intravenous drip or hanging water, is a common treatment method in medical treatment. A large dose of injection is injected into the patient's body through intravenous drip. As we all know, the infusion takes a long time, and the height of the infusion bag is higher than the height of the human heart during infusion. Heart pressure, so the recipient of the infusion often sits or lies on the bed. The longer the time, the less the recipient of the infusion will notice the condition of the infusion bag. After the liquid in the infusion bag is transfused, the blood pressure in the vein is high, which will lead The patient's blood reflux occurs, endangering the health of the infused person, and even endangering life in severe cases.

[0002] Infusion, also known as intravenous drip or hanging water, is a common treatment method in medical treatment. A large dose of injection is injected into the patient's body through intravenous drip. As we all know, the infusion takes a long time, and the height of the infusion bag is higher than the height of the human heart during infusion. Heart pressure, so the recipient of the infusion often sits or lies on the bed. The longer the time, the less the recipient of the infusion will notice the condition of the infusion bag. After the liquid in the infusion bag is transfused, the blood pressure in the vein is high, which will lead The patient's blood reflux occurs, endangering the health of the infused person, and even endangering life in serious cases

[0003] In response to these problems, some alarms are gradually appearing in medical devices. These alarms use various sensors, such as fluid sensors, infrared sensors, etc., or modify the infusion tube, or directly hang on the infusion tube. There are expensive and cheap ones. , the plug-in type is usually very cheap, the price is between 15 yuan and 20 yuan, but the plug-in type is usually considered from the liquid in the infusion tube, so there are more infrared sensors, and infrared rays are more or less It will be affected by the light, and there will be some restrictions when using it, which makes the stability not good
