A kind of terminal phase of intravenous injection autoalarm

Technical field

This utility model relates to a kind of controlled terminal phase of intravenous injection autoalarm.The alarm that medicinal liquid in a kind of specifically prompting medical worker, patient and the entourage's infusion bottle (bag) is about to use up.

Background technology

Venous transfusion is one of the most frequently used clinical treatment method, is important treatment route of administration.Hospitals at different levels all have a large amount of patients accepting transfusion from the outpatient service to the in-patient department every day, and Murphy's dropper is all adopted in general transfusion.Transfusion finishes and need in time pull out pin or change dressings, otherwise will cause blood back, need aerofluxus again, adverse consequences such as puncture again.Because transfusion time is generally all grown (dozens of minutes is to several hrs), the worry medicinal liquid is totally lost and can not be in time found but patient or entourage want to have a rest, thereby bring mental pressure, influence that patient has a rest and rehabilitation to patient and entourage, and the tour that the nurse must not stop, the especially patient that will manage more for a long time the efficiency of management low, be easy to make mistakes.

At present, though existing various multi-functional infusion pump can realize that transfusion is stopped up, the warning that finishes is sneaked into, infused to bubble on the market, but only lay particular emphasis on the occasion of transfusions such as needing accurate control of infusing such as anesthetis mostly, only just meaningful to the use of only a few patient and special medicine.And the very high use inconvenience of cost.

The technology that lays particular emphasis on terminal phase of intravenous injection autoalarm function then mainly contains several classes such as electrode method, weight method, photoelectric detection method and droplet counting evaluation time method, and they cut both ways: the electrode method need in medicine bottle (bag), insert electrode on the bottle stopper, electrode needs sterilization, brings potential safety hazard; The bigger use inconvenience of weight method error; Photoelectric detection method generally can only be installed in detecting element on the Murphy's dropper, the one, because the deadweight of detecting element is dragged down transfusion device easily from medicine bottle (bag), the 2nd, detection sensitivity is subjected to the influence of medicinal liquid color, the 3rd, find that transfusion residue medicinal liquid liquid level when finishing reduced to dropper, transfusion finishes obtaining of signal inclined to one side evening, unfavorable to changing medicine bottle or pulling out the pin operation; Droplet counting evaluation time method also need convert when using time and easily produce estimation error;

Finish and automatically detect, safety detection probe easy inadequately and may pollute deficiencies such as medicine in order to overcome existing transfusion, proposed this utility model with the use of alarm device.

Summary of the invention

This utility model provides a kind of controlled terminal phase of intravenous injection autoalarm, this device realizes non-contact detection and reports to the police having of transfusion medicine bottle (or medicated bag) inner liquid medicine is incompetent, is not subjected to the influence, safe in utilization, easy to operate and cost is lower of medicinal liquid color, viscosity, medicine liquid ingredient.In order to solve the problem of above-mentioned existence, this utility model adopts following technical proposals.

A kind of controlled terminal phase of intravenous injection autoalarm.Comprise detection probe and probe bearing, self-locking swivel joint, alarm and spring opening clamper, a side that it is characterized in that spring opening clamper connects power supply and alarm, opposite side connects the self-locking swivel joint, and the self-locking swivel joint connects the probe bearing, installation and measuring probe on the bearing.Whole device is fixed on medicine bottle (bag) bottleneck of infusing by the opening clamper, and detection probe places near bottle liquid level that the setting in (bag) outside is reported to the police, and the realization non-contact detection that has or not of transfusion medicine bottle (or medicated bag) inner liquid medicine is also reported to the police.

Described detection probe comprises and detects pole plate, oscillating circuit, amplification and shaping circuit, and all is encapsulated in the tubular protective cover, and pole plate is as sensing element, be in probe foremost.
