Description

A drop container fixing device and a monitoring device equipped with the same {DRIP CHAMBER FIXTURE DEIVCE, AND MONITORING DEVICE HAVING THIS}

The present invention relates to a drop container fixing device, and more particularly, a drop container fixing device for fixing the drop container to an infusion monitoring device capable of preventing safety accidents according to the infusion rate of infusion in advance, and a monitoring device having the same. It is about.

In general, in hospitals, intravenous therapy is used in which an injection needle is inserted and injected directly into a vein to supply fluids, drugs, or blood to the human body. In the intravenous injection therapy, fluid is injected directly into the vein, so that an accurate and rapid effect is obtained.

For intravenous injection therapy, in most hospitals, nurses use an infusion set consisting of an infusion container, infusion dropper, infusion line, flow controller, and injection needle. The infusion rate of the infusion solution was calculated, and the infusion rate of the infusion solution was directly adjusted with the naked eye using the flow controller of the infusion solution set.

However, as the nurse manually controls the infusion rate of the fluid as described above, if the infusion rate of fluid injected into the patient's vein is high, excessive fluid infusion may occur and side effects may occur. Insufficient infusion can significantly reduce the efficacy of the fluid.

In addition, since it is difficult to accurately match the infusion rate according to the prescription due to manual control by a nurse, the infusion rate is not constant depending on the person controlling it, and the medical staff must periodically check the remaining amount of infusion. There was this wasted problem. This is the same when injecting blood or drugs into the patient.

Therefore, in the case of injecting an infusion solution, it is important that the infusion solution is injected at an accurate rate according to the prescription.

As a prior art, FIG. 1 is an overall configuration diagram of an infusion set, and FIG. 2 is a partial perspective view of a monitoring device. 1 and 2, in the infusion device 190, a drop container 192 is provided under the infusion bag 191 containing the infusion solution, and an adjustment roller 196 is provided under the drop container 192. When the flow rate controller 194 to which the flow rate is controlled is disposed, the fluid is supplied into the patient's body through the tube 198.

In addition, the monitoring device 200 is arranged to surround the drop container 192, and the monitoring device 200 includes a main body 210, a cutout 211, and a window 213, and the window ( Through 213), the flow rate of the sap can be displayed.

As described above, a fluid infusion monitoring device has been developed that is mounted directly on the dropper to sense the infusion rate of the fluid and displays it.

Meanwhile, research on a fixing device for fixing various types of drop containers having various sizes or various shapes to the main body of the monitoring device is also being conducted.

The contents described in the background art mentioned above are prepared only to understand the background art of the present invention, and thus may include content other than the known art already known to those skilled in the art.
