Abstract
The utility model relates to a portable infusion device with automatic alarm and interception, which is composed of a pressure source device, an infusion bottle, a Murphy's dropper, a liquid-level detection alarm device and an electromagnetic interception device, wherein a gas source automatic interception float is arranged in an observing bottle of the Murphy's dropper. The portable infusion device pushes medicine liquid into a human body by gas pressure above the liquid level of the infusion bottle. When the medicine liquid drops to the alarm liquid level, the alarm device can give a sound and light alarm, the electromagnetic interception device can intercept a flow channel of the Murphy's dropper, and the float in the observing bottle can close off the flow channel of the dropper to prevent pressure air from entering the human body. The utility model has the advantage of high infusion safety, and the utility model can be suitable for various environmental conditions.
Description
It is the portable infusion device of transfusion motive force with the pressure air that this utility model relates to a kind of.
The patent No. is 90212519.2 Chinese utility model patent, a kind of transfusion device is disclosed, it is by Murphy type burette, infusion bottle and pressure gas source device constitute, liquid in Murphy type burette and the infusion bottle communicates, infusion bottle liquid level superjacent air space and compressed air source unit are connected, source of the gas automatic-diversion closure float is set in the observation bottle of Murphy type burette, this transfusion device is that the pressure air with liquid level top in the infusion bottle is a motive force, promote medicinal liquid and enter human body, transfusion speed is stable, after medicinal liquid is totally lost, block source of the gas automatically, can use in patient's the way passing on various forms of transport by the float in the observation bottle.The release of this transfusion device has been started the beginning of developing safe transfusion system, for the development of safe transfusion system technology is laid a good foundation.But, this transfusion device is perfect not enough, also exist the place of some shortcomings, the float that only depends in the observation bottle that blocks of first source of the gas is realized, the source of the gas that other is set does not again block measure, in case the imprecision that cooperates of float and observation bottle neck, pressure air will enter human body, cause the accident, so its safety is high not enough.Its two, after the medicinal liquid in the infusion bottle is totally lost, can not in time point out the nursing staff, ask the medical worker to pull out transfusion needle, deal with the aftermath of, the trend that causes adverse consequences to patient is arranged.
The purpose of this utility model is to avoid the prior art weak point and provides a kind of, when the medicinal liquid of infusion bottle will be totally lost, in time sends prompting nursing staff's audible and visible alarm, and blocks the transfusion device of dropper circulation automatically.
This utility model is to succeed in developing on the basis of above-mentioned transfusion device, is the development to this transfusion device, has more complete performance.
Realize the transfusion device of this utility model purpose, comprise by the hand membrane pump, the air filtration film, air storage chamber, the pressure gas source device that the thin film pressure maintaining valve constitutes, Murphy type burette, infusion bottle, Level Detection alarm control unit and electromagnetism cut-off equipment, in the Murphy type burette observation bottle source of the gas is set and blocks float automatically, liquid in the infusion bottle is communicated with Murphy type burette, the liquid level superjacent air space is communicated with the pressure gas source device by conduit, the Level Detection alarm control unit is by liquid level detector, controller dams, audible-visual annunciator and supply unit constitute, the detection signal emitting head of liquid level detector and signal receive a correspondence and are arranged in the outer alarm liquid level horizontal plane of infusion bottle, the signal output interface of liquid level detector is connected with the signal input port of dam controller and audible-visual annunciator respectively, supply unit is respectively to liquid level detector, dam controller and audible-visual annunciator provides power supply, alarm lamp and speaker are connected in the power output interface of audible-visual annunciator, the electromagnetism cut-off equipment is made of the solenoid actuated mechanism and the mechanism of damming, the power interface of solenoid actuated mechanism is connected with the power output interface of the controller that dams, the fore shaft of actuator of damming is positioned at the observation bottle below of Murphy type burette, and Murphy type burette passes from fore shaft.
This utility model also can further be taked following technical measures, then more helps this utility model purpose and realizes:
Solenoid actuated mechanism is made of electric magnet, control stick, support, back-moving spring, control stick and support are hinged, spring is positioned at outside the hinge, one end connects control stick, the other end connects support, control stick is outstanding to be propped up above electric magnet, and with the execution bar phase configuration of actuator, the position of bar is carried out in control.Actuator constitutes by carrying out bar, spring, spring base, moving cutting edge and quiet cutting edge, and spring and moving cutting edge are fixed on the both sides of carrying out the same end of bar, and moving cutting edge is corresponding with quiet cutting edge, constitutes the fore shaft of the actuator of damming.
This utility model in use, when the medicinal liquid liquid level in the infusion bottle drops to the alarm liquid level, the signal that the signal emitting head of liquid level detector sends is received head and receives, be transferred to liquid level detector, through handling, liquid level detector sends alarm signal and dams signal to the audible-visual annunciator and the controller that dams respectively, audible-visual annunciator receives the report for police service behind the signal, through handling, connect the power supply of alarm lamp and speaker, send audible and visible alarm.After the controller that dams is received the signal that dams, through handling, connect the power supply of solenoid actuated mechanism, after the electric magnet energized, electromagnetic force is inhaled control stick down, and it is out of hand to carry out bar, under the effect of other end tension spring, rotate, make the moving cutting edge that is fixed on tension spring opposite one side rely on quiet cutting edge, form the fore shaft that dams, the Murphy type tube pipeline that passes fore shaft is blocked.When the medicinal liquid in the observation bottle will flow, be arranged on the float sealing pore in the observation bottle, prevent that pressure air from entering human body.
In observation bottle of the present utility model, float is not set, can obtains reasonable warning cutout effect yet.
This utility model compared with the prior art, Tu Chu advantage is the most, when the medicinal liquid in the infusion bottle will be totally lost, can in time send audible and visible alarm, the prompting nursing staff ask the medical worker to pull up transfusion needle, deal with the aftermath of.And start the electromagnetism cut-off equipment simultaneously automatically, the runner of sealing Murphy type burette prevents that pressure air from entering human body.When the medicinal liquid in the observation bottle had flowed, float sealed the dropper runner, had increased again to prevent that together pressure air from entering the defence line of human body, used safe especially.For disposable dropper, in order to reduce the cost of transfusion device, this utility model has very high safety equally without float sealing dropper runner.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 be in the accompanying drawing 1 A-A to partial sectional view.
Below in conjunction with the explanation of accompanying drawing drawing, provide an embodiment of the present utility model.
