Abstract
The utility model discloses an infusion alarm which belongs to the technical field of medical instruments and consists of an infusion bottle, a dropper, an acoustic alarm circuit, a manual adjuster, an air filter and a needle, which are sequentially connected by a conduit. The alarm switch of the acoustic alarm circuit consists of an alarm switch upper electrode and an alarm switch lower electrode which are both arranged between the infusion bottle and the dropper and form a pair, wherein, the connection and the disconnection of the alarm switch upper electrode and an alarm switch lower electrode are controlled by water level. Due to the adoption of the structure, the utility model has the advantages of simple circuit structure and low production cost.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of infusion alarm of infusing that is used to.
Background technology
At present, still traditional infusion devices that adopt need special nursing staff to nurse more aspect medical transfusion, should in time notify doctor or nurse to handle when medicinal liquid is totally lost, and make troubles for families of patients or nursing staff.If nursing is not good at for the moment, the malpractice that Yi Fashengyin transfusion reason causes.
The content of utility model
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, infusion alarm that cost of manufacture is low is provided.
This utility model comprises that infusion bottle, dropper, audible alarm circuit, hand adjustment device, air filter and syringe needle connect to form in turn through conduit, the alarm switch of described audible alarm circuit is made of the upper and lower electrode of alarm switch of being located at a pair of water level control break-make between infusion bottle and the dropper.
Because of the alarm switch upper/lower electrode is inserted in the infusion syrup, instrument was in the supervision armed state when patient infused, and audible alarm circuit is not worked; When infusion syrup drips to when being lower than the alarm switch top electrode, audible alarm circuit begins to report to the police.
This utility model has the advantage that circuit structure is simple, cost of manufacture is low owing to adopt above structure.
Description of drawings
Fig. 1 is the structural representation of a kind of infusion alarm of this utility model;
Fig. 2 is the warning circuit sketch map of infusion alarm shown in Figure 1.
The specific embodiment
As shown in Figure 1, this utility model comprises that infusion bottle 1, dropper 2, audible alarm circuit, hand adjustment device 3, air filter 4 and syringe needle 5 connect to form in turn through conduit 6, the alarm switch of described audible alarm circuit is made of the upper and lower electrode 7 of alarm switch of being located at a pair of water level control break-make between infusion bottle and the dropper.
As shown in Figure 2, the complementary oscillating circuit that this utility model warning circuit is made up of two audion V1 and V2, upper and lower electrode is in parallel with base stage and the emitter stage of audion V1 respectively, the base stage of V1 is divided into the two-way parallel connection after connecting resistance R 1, receive positive source behind one tunnel series connection R2, connect straight power cathode behind another road series capacitance and a dynamic loudspeaker Y, power supply adopts the 3V unidirectional current.
