Abstract

The invention relates to a safe infusion set for hospital clinical transfusion, comprising dripping tube, magnetic floating valve and magnetic induction alarm, which can stop transfusion and alarm automatically when transfusion is accomplished. When transfusion is normal, the magnetic floating valve is floated and the magnetic induction circuit of magnetic induction alarm is opened normally so that the infusion can not give an alarm. When transfusion is accomplished the liquid level of dripping tube is dropped and the magnetic floating valve on the liquid level is also dropped so that the magnetic induction gives an alarm. Subsequently the floating valve is not dropped continuously until it plugs the port of dripping tube and the transfusion is stopped. Liquid in tube is balanced statically so that the possibility that air enters into vein can be avoided and blood returning can not be generated. When an alarm is given sound and light alarm signals are outputted at the same time and calling system in hospital is on. When bottle in transfusion is changed, the floating valve is floated by buoyancy or it is returned manually. The safe infusion set works continuously.

Description

Safe infusion apparatus

Technical field: the present invention relates to a kind of medical apparatus and instruments, especially medical Transfusion device.

Background technology: infusion process often needs accompanying and attending to of patient and family members, takes time and effort, and also brings big workload to medical personnel.And now current mould the also extremely difficult observation of bottle packing and hold artificial warning opportunity, very easily cause accidents such as blood back.

Still there is not the safe infusion apparatus supply in the market.The infusion alarm of patent applied for is mainly three classes, and a kind of is to be changed to the basis with the infusion bottle gravity difference, but because bottle material difference need accurately measure bottle weight before the operation, so practicality is not strong, is difficult to use in practice; The 2nd, insert liquid with electrode needle, but can make medicinal liquid produce ionization like this, the relevant regulations of the technical method violation Ministry of Public Health that this and medicinal liquid directly contact; The 3rd, be means with the sensor measurement of liquid level, but it is very big influenced by the infusion bottle material, and price is higher, be difficult to the marketization and use, and can only report to the police and can not cut off infusion process.More than three kinds of patent achievements be difficult on market, promote, therefore still do not have at present on the market and go for infusing arbitrarily material, operation without any debugging can be cut off infusion process automatically, automatically report to the police, and the reusable safe infusion apparatus of finishing to transfusion.

Summary of the invention: purpose of the present invention, be to provide transfusion device safe, economic, practical, that extensively be suitable for, can when transfusion finishes, end transfusion voluntarily, send sound and light alarm simultaneously automatically, and the hospital care system that is dynamically connected certainly, and the reusable safe infusion apparatus of finishing to transfusion.Its product is not influenced by any infusion bottle matter and medicinal liquid kind, does not have directly with medicinal liquid to contact, have easy and simple to handle, safe and harmless, wide adaptability, economical cheap, the quality of production is easily controlled, fault rate is extremely low, the characteristics that not influenced by infusion process.

Description of drawings:

1, accompanying drawing 1＜safe infusion apparatus 〉, illustrate safe infusion apparatus by drip tube 1, contain the float valve 2 of magnetic, fixedly cingulum or shell 3, magnetic induction warning circuit 11 is formed; The upper and lower displacement of the magnetic-type float valve 2 on the liquid level is partly reported to the police magnetic induction, and float valve 2 continues to descend simultaneously, blocks the mouth of pipe, and infusion process is ended;

2, accompanying drawing 2＜magnetic-type float valve 〉, further specify magnetic-type float valve 2, be built in drip tube 1, its structure and effect are: top cavity part 5 makes float valve 2 float on liquid level; Lower magnet part 4 is in order to opening and closing magnetic conduction circuitry 7, and can seal and block the bottom infusion port; When preventing float valve 2 come-ups, blocks upper limit 6 the top infusion port;

3, accompanying drawing 3＜warning circuit module 〉, warning circuit 11 is described by magnetic induction part 7, on and off switch 10, buzzer and light emitting diode 8, signal output 9 is formed.

The specific embodiment: following contrast description of drawings implementation method:

1, accompanying drawing 2＜magnetic float valve〉in, drip tube 1 (luxuriant Fei Shi pipe can be transformed by the magnetic action requirement), built-in contains the float valve 2 of magnetic, and the magnetic induction warning circuit is put on the side.Float valve 2 is the safety non-toxic material, is preferably planchet shape, and circle is avette, multiple shape such as wedge shape.Float valve 2 is made of cavity part 4 and magnet part 5.When normal infusion, liquid is full in the drip tube 1, and float valve 2 rises to upper limit 6, and warning circuit is not reported to the police; When transfusion finishes, drip tube 1 liquid level descends, and float valve 2 also descends thereupon, and the magnetic induction part 7 in the warning circuit that the displacement of magnet part 4 is put the side produces magnetic action, and warning circuit is reported to the police.When float valve 2 continues to drop to drip tube 1 bottom, block drip tube 1 bottom infusion port at the bottom of its valve, liquid level top tube chamber forms negative pressure in the tube for transfusion, and transfusion is ended.The outer full static balance state that also reaches gradually of transfusion liquid in pipe of patient body's this moment, depletion of blood condensation point in the transfusion needle has effectively been protected patient.After heavily changing dressings, drip tube 1 inner liquid medicine is full, is positioned at buoyancy that the air bubble structure 5 of the float valve 2 of drip tube 1 bottom produces and drives magnet valve and come back to upper limit 6, and transfusion continues.Also can manually overturn and make float valve 2 buoyance lifts.

2, warning circuit 11 minutes magnetic conduction circuitry parts, sound and light alarms partly reach and often open signal port three parts, and control with on and off switch 10.It is often opened segment signal output and can match to comprising or not being included in the alarm circuit.Magnetic induction part 7 refers to utilize magnetic force to produce the electric elements that open and close, and comprises tongue tube, mutual inductor etc., but be not limited to tongue tube and mutual inductor etc.Sound and light alarm part 8 adds light emitting diode including, but not limited to buzzer.Signal output 9 is normal open circuit, connects the original calling system button of hospital.As accompanying drawing 3, magnetic induction part 7 is tongue tube or mutual inductor, and acousto-optic part 8 is alarm buzzer and light emitting diode, and signal output 9 includes but not limited to contact switch and door trip;

3, when float valve 2 descend make magnetic induction part 7 closed circuit after, warning circuit is connected, the 8 luminous warnings of sound and light alarm part are connected the original calling system button of hospital with opening output signal circuit part 9 often, notify nurse on duty automatically.The nurse can be by switch 10 with its power-off restoration.

4, warning circuit 11 can adopt tongue tube or mutual inductor equimagnetic inductive means, and purpose is to utilize magnetic force to make closed the getting final product of component of open circuit originally.Closed circuit is connected the sound and light alarm part, exports an outside connected switch contact signal then.Present this warning circuit module is very general on market, commercialized supply, and according to the principle difference, kind is also a lot, can both be applicable to the warning circuit part of this transfusion device.Therefore no longer specifically narrate the circuit of alarm and form structure.Serve as the letter example with a kind of trigger process of tongue tube alarm circuit only: magnet valve is instantaneous when leaving tongue tube, reed switch contact moment closure, and monostable circuit CP input rises to high level, and its outfan is a high level state by original low level state saltus step.Level output connects sound and light alarm part and output signal part after the concussion leveling.
