Abstract
An automatic stopping infusion set comprises a cork puncturing device, a dripping funnel, a tube, a liquid inlet with a liquid medicine filter having a stop device which can be opened and closed, and an injection needle, wherein all components are connected and communicated with each other. The infusion set also comprises a flow regulator sleeved over the tube. During an infusion process, the stop device is pushed by the gravity of liquid medicine in the tube. After the liquid inlet is opened, liquid medicine runs into the liquid medicine filter. When the liquid medicine in the tube runs out and entirely flows into the liquid medicine filter, the stop device is closed since the gravity of the liquid medicine in the tube no longer exists, thereby preventing air from entering into the liquid medicine filter and from entering into the blood vessel to endanger a patient.
Description
Affiliated technical field
This utility model belongs to medical apparatus and instruments, and especially venous transfusion is used automatically ends the liquid transfusion device.
Background technology
The transfusion device that present venous transfusion is used is after the medical liquid container inner liquid medicine drips off, fail in time to close transfusion device as the nurse with the flow regulator folder, air just can be through transfusion device and intravasation, bring harm to the patient, and have patent 2005800301949 to invent: design safety mechanism in dropping funnel or between dropping funnel and the flexible pipe, after last medicinal liquid is flowed through release mechanism, only close transfusion device, in the dropping funnel of air prevention more than release mechanism, but have between present infusion unit titrimeter and the liquid medicine filter greater than 1.2 meters long pipelines, so just make release mechanism following, be trapped in the pipeline and can't inject in patient's body, cause waste than the more medicinal liquid in the long pipe runs.
Summary of the invention
In order to overcome transfusion device that present venous transfusion uses after the medical liquid container inner liquid medicine drips off, fail in time to close transfusion device as the nurse with the flow regulator folder, air just can be through transfusion device and intravasation, bring harm to the patient, and have patent 2005800301949 to invent: design safety mechanism in dropping funnel or between dropping funnel and the flexible pipe, after last medicinal liquid is flowed through release mechanism, only close transfusion device, air is stoped in the above dropping funnel of release mechanism, but have between present infusion unit titrimeter and the liquid medicine filter greater than 1.2 meters long pipelines, so just make that release mechanism is following to be trapped in the pipeline than the more medicinal liquid in the long pipe runs, can't inject in patient's body and wasting defective.
Automatically the liquid transfusion device that ends of the present utility model: by bottle plug puncture unit, dropping funnel, pipeline, inlet is provided with can be opened and the closed liquid medicine filter that only closes device, entry needle connects perforation, and sheathed flow regulator is formed outside pipeline, only close device in the setting of liquid medicine filter inlet, when medicinal liquid will flow into liquid medicine filter, only closing device opens because of the gravity promotion of liquid in the pipeline, medicinal liquid flows into liquid medicine filter, when no medicinal liquid can flow in medicinal liquid drips off the back pipeline, because of pipeline no liquid, make need that the gravity of liquid promotes to open in the pipeline only close device, will open and closed inlet, stop air admission, thereby make after the medical liquid container inner liquid medicine drips off, the pipeline inner liquid medicine still can inject in patient's body between dropping funnel and the liquid medicine filter, and air is stoped in the front end pipeline that only closes device of liquid medicine filter inlet.After so both can having avoided medicinal liquid to drip off, fail in time to close transfusion device with the flow regulator folder as the nurse, air just can be through transfusion device and intravasation brings harm to the patient, avoided more medicinal liquid to be trapped in the pipeline again, can't inject in patient's body and wasting defective.

The specific embodiment
Join below with accompanying drawing this utility model is specified.
Embodiment:
As scheming: end the liquid transfusion device automatically, by bottle plug puncture unit (1), dropping funnel (2), pipeline (6), inlet (3) is provided with the liquid medicine filter (5) that only closes device (4), entry needle (7) connects perforation, and sheathed flow regulator (8) is formed outside pipeline (6), the gravity of the interior liquid of pipeline during transfusion (6) promotes only closing device (4), open inlet (3), medicinal liquid flows into liquid medicine filter (5), after medicinal liquid drips off, after pipeline (6) liquid all flows into liquid medicine filter (5), only closing device (4) closes because of the promotion of the interior liquid gravity of no pipeline (6), stop air admission liquid medicine filter (5), thereby avoid the air admission blood vessel, bring harm to the patient.
Claims (1)
1. end the liquid transfusion device automatically, be provided with the liquid medicine filter that only closes device, the entry needle that to open with closed by bottle plug puncture unit, dropping funnel, pipeline, inlet and be connected perforation, and sheathed flow regulator is formed outside pipeline, it is characterized in that: the liquid medicine filter inlet is provided with can be opened and the closed device that only closes.
