Description
[technical field]
The present invention relates to medical instruments training equipment, be specifically related to a kind of number of infusion drops measuring system.
[background technology]
The equipment that Hospitals at Present is used for Hanging type transfusion is mainly divided into two large classes, and a class is infusion pump that is expensive, that provide several functions; One class is then for solving the small-sized infusion alarm paying close attention to transfusion condition at any time.Infusion pump price is high, how to use in intensive care unit, and is not suitable for all sufferers having transfusion to require.Infusion alarm is then paid attention to because cost performance is high, and the research at present for this respect mainly solves dropping liquid measurement problem by the technology of four kinds of principles:
1, check weighing principle: the end being reminded transfusion by the increase and decrease variation of measuring medicinal liquid bottle and whole component weight.But can equipment weight be subject to, because each medicinal liquid bottle, all weight of parts are different, alarm can be caused inaccurate; Also may affect by spring deteriorates, cannot give the alarm accurately
2, acousto-optic principle: by measuring the liquid height in liquid bottle by Photoelectric Detection, converses also surplus how many medicinal liquids, then proposes warning to medical personnel.Current because there will be " bimodal " benefit in the measurements, measure the appearance of inaccurate situation so sometimes there will be.
3, principle of flotation: its principle is similar to the ball float of upper water in household toilet, is introduced in new structure by medicinal liquid, utilizes the buoyancy aid in structure to measure and controls medicinal liquid output, thus the not enough situation of alarm medicinal liquid.But medicinal liquid is rebooted in a structure inevitably contaminated.
4, infrared ray principle: measure drop by infrared transmitter signal, then extrapolates how many medicinal liquids in addition.Shortcoming is when alarm starts, quits work not sure, easily causes managerial confusion, such as emptyly reports to the police; Secondly alarm can only singlely charge, and when hospital uses in a large number, brings the problems such as charge efficiency is low, charge maintenance work is heavy, equipment investment is large.
[summary of the invention]
In order to overcome the deficiencies in the prior art, the invention provides a kind of number of infusion drops measuring system, adopting vibrating sensor to measure number of infusion drops, make use convenient.
A kind of number of infusion drops measuring system, comprises tube for transfusion, murphy ' s dropper, also comprises dropping liquid siren, care station siren.
Dropping liquid siren involving vibrations sensor, microprocessor, control panel, wireless launcher, radio receiver, display device I, buzzer, supply unit.Vibrating sensor is connected with microprocessor, and microprocessor is connected with control panel, and control panel is connected with display device I, wireless launcher, radio receiver, buzzer, supply unit.Display device I comprises display screen, reset key, on & off switch, rise key, down key, buzzer, display screen can show dropping liquid siren sequence number, transfusion time started and transfusion speed, Liquid dropping bottle capacity, can reset after having infused, the sequence number of every platform dropping liquid siren can be arranged by care station siren.
Preferably, dropping liquid siren is arranged on bottom murphy ' s dropper.
Preferably, medicinal liquid selectable capacity selects 50ml, 100ml, 150ml, 200ml, 250ml, 500ml.
The operation principle of dropping liquid siren is: nurse, before starting transfusion, sets medicinal liquid capacity according to infusion bottle medicinal liquid capacity by the rise key of display device I, down key; Vibrating sensor will be collected dropping liquid vibration data and be delivered in microprocessor; Vibration data is compared analysis by microprocessor, distinguishes the vibration that transfusion produces and the vibration produced because patient walks about, and vibration data record of infusing, calculate transfusion speed; Microprocessor goes out medicinal liquid surplus situation and transfusion end time in conjunction with medicinal liquid calculation of capacity; Transfusion speed, medicinal liquid surplus and transfusion end time are transferred on the display screen of display device I by control panel, and the signals such as transfusion speed, medicinal liquid surplus and transfusion end time are transferred to care station siren via wireless launcher.
Preferably, the data comparative analysis of microprocessor is classified as non-dropping liquid data by collecting the large vibration data of amplitude in vibrating sensor, and data little for amplitude are classified as dropping liquid data.
Care station siren comprises microprocessor, control panel, wireless launcher, radio receiver, display device II, buzzer, supply unit.Microprocessor is connected with control panel, and control panel is connected with display device II, wireless launcher, radio receiver, buzzer, supply unit.Display device II comprises display screen, raises key, down key, key of sounding all clear, buzzer, and display screen can show dropping liquid siren sequence number, transfusion time started, transfusion speed, medicinal liquid surplus and transfusion end time.
Preferably, care station siren is by nurse's keeping.
Care station siren operation principle is: care station siren receives the signal of dropping liquid siren by radio system, care station siren can check the transfusion speed of whole dropping liquid siren, medicinal liquid surplus and transfusion end time by the rise key of display device II and down key, care station siren can by wireless launcher by the instruction issue of sounding all clear to dropping liquid siren.
Compared with prior art, the advantage that the present invention program has to detect transfusion drip speed, also by after droplet counting, can go out medicinal liquid surplus situation in conjunction with medicinal liquid calculation of capacity, can also distinguish the vibration that transfusion produces and the vibration produced because patient walks about; The number of infusion drops measuring system of Simplicity in Design had both facilitated medical personnel to observe whole sufferer dropping liquid situation in drip chamber, saved nurses manpower resources costs; Also facilitate sufferer to observe dropping liquid remaining time, patient comfort degree strengthens, and improves patient and family members to medical personnel's satisfaction.
