Abstract
The utility model relates to an electrode for an electrode type venous transfusion alarm device, which is matched with an alarm device for venous transfusion. The utility model comprises a probe 4 and a probe 5. The probe 4 and the probe 5 are conductive metal to form a pair of electrodes. One end of the utility model penetrates through a bottle cover of a transfusion bottle to immerse in liquid media 1. The other end of the utility model is connected with the input end of a switch circuit. Due to the adoption of the structure, the probe 4 and the probe 5 replace an air exhaust needle head 2 and a transfusion needle head 3 to serve as the input end of an alarm circuit. The short circuit of the electrodes can be effectively prevented. The alarm device has the advantage of stable operation.
Description
This utility model relates to a kind of probe-type electrode, the particularly a kind of and matching used electrode of electric pole type intravenous transfusion alarm.
Chinese patent 91204498.5 discloses a kind of electric pole type intravenous transfusion alarm, two electrodes of warning circuit input are made of the aerofluxus syringe needle 2 and the infusion needle 3 that are immersed in the liquid in infusion bottle medium 1, when aerofluxus syringe needle 2 contacts with infusion needle 3, two electric pole short circuits, alarm lost efficacy, even liquid medium drips off, can not report to the police yet, very easily cause malpractice.
The purpose of this utility model provides a kind of probe-type electrode, replaces aerofluxus syringe needle 2 and infusion needle 3, as the input of warning circuit, effectively prevents electric pole short circuit.
The technical solution of the utility model is as follows:
A kind of electrode that is used for the electric pole type intravenous transfusion alarm, with the supporting use of intravenous transfusion alarm, its structure comprises probe 4 and probe 5, probe 4, probe 5 are conducting metal and constitute pair of electrodes, the bottle cap that the one end penetrates infusion bottle is immersed in the liquid medium 1, and end is connected with the input of on-off circuit in addition.
Described probe 4 and probe 5 are wrapped to one and are insulated cover 7 by an insulation sleeve 7 and separate, the needle point of probe 4 and probe 5 all is exposed at the insulation sleeve outside, be separated with an insulation 8 between the needle point of probe 4 and probe 5, insulation 8 is connected as a single entity with insulation sleeve 7, and its head becomes needle-like, probe 4 links to each other with the input of warning circuit respectively with probe 5, constitutes counter electrode.
Described probe 4 is longer than probe 5, and a cavity is arranged in the probe 5, and probe 4 passes the cavity in the probe 5, is separated with insulating barrier 6 between probe 4 and the probe 5, and probe 4 links to each other with the input of warning circuit respectively with probe 5, constitutes pair of electrodes.
The top of described insulating barrier 6 is higher than or puts down in probe 5.
The outside of described probe 5 also is surrounded by an insulation sleeve 7.
Two relative on the described insulation sleeve 7 positions respectively are provided with a groove 9, and groove 9 is provided with asperities.
Owing to adopt above-mentioned structure, probe 4 and probe 5 replace aerofluxus syringe needle 2 and infusion needle 3, as the input of warning circuit, effectively prevent electric pole short circuit, and alarm work is stable.
Below in conjunction with drawings and Examples this utility model is described in further detail:
