Embodiment Construction

[0007] The puncturer, the plastic box and the two electrodes are formed into one body through injection molding through the mold; the battery, piezoelectric ceramic sheet, alarm circuit, power switch, indicator light, etc. are connected and put into the box. The needle valve is made of non-toxic polymer plastic with a density lower than that of water; the outer diameter of the counterweight cylinder is smaller than the outer diameter of the dropper connector, but larger than the inner diameter of the connector; the outer diameter of the guide post is smaller than the inner diameter of the connector; The cone valve part is located between the counterweight round bolt and the guide post; the total length of the needle valve is greater than the length of the Murphy dropper. Put the guide post partly into the connector, and insert it into the dropper from the lower opening of the Murphy dropper.

[0008] Assemble the exhaust tube, puncture device with alarm, infusion tube, Murphy ...

Abstract

The invention relates to a disposable medical safe infusion apparatus, which is capable of automatically sounding an alarm when the liquid medicine in an infusion bottle is nearly running out, and automatically closing an infusion catheter when the liquid medicine drops to the bottom of a Murphy pipette, so as to stop the liquid medicine to further flow downwards. The medical safe infusion apparatus is characterized in that: an alarm is arranged on a puncture outfit in order to give an alarm when the liquid medicine is running out; a needle valve able to suspend in the liquid medicine is arranged inside the Murphy pipette, so that the infusion catheter can be automatically closed when the liquid flows to the bottom of the pipette, so as to prevent the liquid from dropping and protect the patients from the dangers of blood backflow and air embolism.

Description

technical field [0001] The invention relates to a medical instrument for infusion, especially a disposable medical safety infusion device which can automatically alarm when the infusion is finished and automatically close the infusion tube when the liquid medicine drops to the bottom of the muphy dropper to prevent the liquid medicine from flowing down further. Background technique [0002] At present, the known infusion set is made up of parts such as puncture device, exhaust pipe, infusion tube, muphyll dropper, regulator. In use, when the infusion is completed and the liquid medicine is not replaced or the needle is pulled out in time, the risk of blood backflow or air embolism may occur to the patient. Contents of the invention [0003] In order to overcome the risk of blood backflow or air embolism that the existing infusion set may cause to patients during use, the invention provides a safety infusion set. The infusion set can automatically alarm when the infusion i...
