Abstract
The invention discloses an infusion device with an automatic air embolism alarm function. On the basis of an original disposable infusion device, an ultrasonic air detector and an automatic alarm device are additionally arranged in the system. For one aspect, nurses and accompanying persons are reminded; and for the other aspect, patients are prevented from generating air embolism to avoid medical negligence. The infusion device is convenient to use, beneficial to medical care and has wide application market.
Description
Technical field
The present invention relates to a kind of transfusion device that has the automatic warning function of air embolism, belong to medical instruments field.
Background technology
At present, widely used transfusion device all is a disposable transfusion device, generally all need in the process of transfusion the retinue accompany or the nurse need regularly check, prevent still not pull out pin after liquid is totally lost.If retinue or nurse's carelessness are perhaps forgotten, possibly cause a large amount of air admission patients' body vein to produce air embolism and backflow of blood entering transfusion device.When air through behind the transfusion device vein, blood can not be got in the lung, cause severe depletion of oxygen and cause body dead; As get into heart coronary artery, and can block coronary circulation, cause serious cardiac dysfunction, cause body dead.Gas is if pass through pulmonary artery--pulmonary vein--and left atrium--left ventricle--whole body is tremulous pulse everywhere---corresponding arterial thrombosis, like limb artery embolization, cerebral embolism etc. cause corresponding symptom, consequence is more serious.
Summary of the invention
Take place for fear of this malpractice situation, generally need the people patient next door guard, yet always have carelessness.The design has increased alarm device on the basis of existing disposable transfusion device, can report to the police when flow of liquid is intact, reminds guard's retinue and nurse, has prevented that the patient from producing air embolism.The design adds ultrasonic air detectors at the infusion tube that drips more than the kettle part of transfusion device, according to the different propagation characteristics of ultrasound wave in different medium, through circuit analysis and processing, thereby can distinguish that the medium in the flow duct to be detected is liquid or air.Think that when within a period of time, detecting air all the time the flow of liquid in the infusion bottle is intact.Report to the police through the flicker warning of LED and the tinkle of bells of buzzer, remind nurse and nurse patient's retinue, thus the function that realization is reported to the police automatically.
The present invention solves that its technical problem adopts
Technical schemeBe: ultrasonic air detectors is placed on the mouth place of tube for transfusion near transfusion device; Use the perception device of this detector as detection signal; When having detected air, report to the police through the flicker warning of startup LED and the tinkle of bells of buzzer, realize the design of anti-air embolism automatic alarm transfusion device.
Of the present invention
Beneficial effectBe,, meanwhile, report to the police, notify nurse and retinue easily through the flicker warning of LED and the tinkle of bells of buzzer through adopting the liquid in the ultrasonic testing infusion bottle.Native system is simple in structure, and precision is higher, and the response time is very fast, can realize whole transfusion room is carried out unified management, and then prevent to cause the patient to produce air embolism because carelessness produces serious consequence, fortuitous event occurs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is an overall schematic of the present invention.
1. drop supports among Fig. 1,2. liquid containing bottle, 3. tube for transfusion, 4. ultrasonic monitor (carrying warning).
The specific embodiment
In Fig. 1, liquid containing bottle (2) is fixed on the drop support (1), and tube for transfusion (3) is fixed on liquid containing bottle (1) mouthful place, and ultrasonic monitor (carrying warning) (4) is fixed on tube for transfusion (3) and compares the position near liquid containing bottle (1) mouth.
Pass through tube for transfusion (3) when not having air when ultrasonic monitor (carrying warning) (4) detects, whole system is in normal operating conditions; When detect through tube for transfusion (3) when air is arranged when ultrasonic monitor (carrying warning) (4); Start the warning function of ultrasonic monitor (carrying warning) (4); Realize the function of warning automatically, reach the effect that realizes reminding nurse and nurse patient's retinue.
Claims (1)
1. a transfusion device that has the automatic warning function of air embolism is characterized in that on the basis of general infusion set, having added Ultrasonic Wave Air Detector and alarm device.
