Description
Technical field
The present invention relates to medical fields, are a kind of infusion apparatuses being automatically stopped infusion and automatic alarm with infusion-completed.
Background technology
Infusion apparatus is a kind of common medical treatment consumptive materials, by aseptic process, establishes channel between vein and liquid, for quiet
Arteries and veins is infused.Generally by intravenous needle or injection needle, needle-covering cap, infusion tube, liquid medicine filter, flow regulator, drop pot, bottle stopper
Eight part connection compositions such as puncture outfit, air filter, infusion segment device also have injection member, dosing mouth etc..In atmospheric pressure
Under effect, the thinner infusion tube of liquid runs down flows into dropping funnel in bottle, when dropping funnel water column pressure is more than vein pressure, the liquid in bottle
Body flows into vein along hose.Work as infusion bottle（Bag）When middle liquid is finished, need to remove or replace infusion bottle in time（Bag）, no
Then, may cause patient blood flow backwards or air enter in patient body, lead to the generation of malpractice.Therefore, it reminds in time
Medical staff removes or replaces infusion bottle（Bag）, it is desirable to special messenger is responsible for guard and it is necessary to which the moment is noticed that whether to be totally lost, and is
One very a hard row to hoe, urgent need is replaced by automatic alarm for transfusion.
The automatic infusion alarm device invented at present generally uses four kinds of principles：
1, it weighs alarm type：According to liquid in infusion bottle weight, when liquid runs low alarm；But not due to each amount of infusion
Together, it needs to be arranged every time, uses pretty troublesome, and measure also inaccurate, cost is also higher.
2, Photoelectric Detection formula：Whether have liquid flow through, reported once without liquid if being detected in woven hose by photoelectric device
It is alert；It needs very accurate detection device and detection to calculate, wrong report is easy for the high liquid of transparency.
3, condenser type alarm：By detecting capacitance variations out-of-date with/without liquid flow, send out alarm signal, oiliness and
Waterborne liquid is big to capacitance variations difference, needs circuit more complicated, and can not generally be automatically stopped infusion, needs artificially dry
In advance.
4, mechanical：Whether diaphragm type, float-ball type are required for carrying out infusion apparatus larger transformation, and structure all compares
It is more complex, cause cost higher, it is inconvenient for use.
The present invention is according to the determination of foregoing invention, and exploitation one kind is simple in structure, at low cost, it is defeated to start and stop automatically
The infusion apparatus of liquid and the mating alarm that can be reused.
Invention content
The object of the present invention is to provide a kind of control of automatic liquid level, it is automatically stopped the high reliability woven hose of infusion and mating
The simple alarm of the repeatable structure utilized.
A kind of automatic start-stop function infusion apparatus and alarm, it is characterised in that use the tapered magnetic float of column and realize liquid level
Detection and sealing function realize warning function in conjunction with battery, buzzer using tongue tube as external detection original paper；Wherein
Float top half is pyramid type, and lower half portion is H-type, realizes sealing function, small magnet is housed inside float.
Present invention topic is realized using following technical scheme：
A kind of automatic start-stop function infusion apparatus and alarm are made of float, warning clip, drop pot three parts；Wherein on float
Half portion is divided into pyramid type, and lower half is H-type, inside has magnet, float is in drop pot；When liquid side is higher in drop pot, float
It can float, the taper surface on top can close drop pot inlet so that liquid cannot enter；When infusion-completed, liquid in pot is dripped
Face can decline, and when liquid level drops to drop pot liquid outlet tubing port, float lower half H-type structure will together be formed with liquid
Sealing surface avoids gas from entering in woven hose, and realization is automatically stopped infusion function；Float internal magnet can trigger alarm clip at this time
In reed switch conduction circuit, drive buzzer warning.
Preferably, the float shell top half is pyramid type, and lower half portion is H-type, and float is Totally-enclosed-type.
Preferably, the float diameter is more than drop pot radius, is highly more than drop pot diameter.
Preferably, the float shell is made using with drop pot same material, and inside is equipped with magnet.
Preferably, the drop pot inlet, liquid outlet woven hose should be inserted into drop pot certain depth.
Preferably, the alarm clamp circuit is made of button cell, tongue tube and buzzer.
Preferably, the warning clip can be also made of complicated WIFI circuits, CPU, realize remote alarming function.
Description of the drawings
Fig. 1 is front view of the present invention.
Specific implementation mode
Principle according to the present invention, a kind of automatic start-stop function infusion apparatus and alarm：
Example 1
As shown in Fig. 1, a kind of automatic start-stop function infusion apparatus and alarm, by drop pot 1, float 2,5 three parts structure of warning clip
At.Wherein float 2 is mounted in drop pot 1, and warning clip 5 is temporarily installed on drop 1 outlet tube of pot.In order to realize sealing function, drip
The inlet and liquid outlet woven hose of pot 1 are inserted into drop pot certain depth.Wherein float 2 has shell and inner magnet 3 to constitute, alarm
Folder 5 is made of clip and circuit, and wherein circuit is by buzzer 5.1, tongue tube 5.2, the composition of battery 5.3.
Wherein 2 top half of float is pyramid type, and lower half is H-type, inside there is magnet 3, when liquid side is higher in drop pot 1
When, float 2 can float, and the taper surface on top can close 1 inlet of drop pot so that liquid cannot enter；When infusion-completed,
Liquid level can decline in drop pot 1, when liquid level drops to the position (drop pot liquid outlet tubing port) of liquid level 2,2 lower half H-type of float
Structure will form sealing surface together with liquid, and gas is avoided to enter in woven hose, and realization is automatically stopped infusion function；It floats at this time
Magnet 3 in son 2 can trigger 5.2 turning circuit of tongue tube in warning clip 5, and buzzer 5.1 is driven to alarm.
The foregoing describe the basic principles and main features and advantages of the present invention of the present invention.The technical staff of the industry answers
