Description
Technical field
The present invention relates to one kind preventing patient's tumble device, belongs to medical auxiliary apparatus technical field.
Background technology
Currently, important link day of the nursing safety as the important indicator and Medical Dispute Prevention for weighing nursing service quality
Benefit is taken seriously, wherein inpatient adverse events are the important contents of clinical safety management.Tumble is related inpatient report
The most adverse events in road, refer to burst, involuntary, unintentional Body Position Change, fall on the ground or lower plane on.Always
People fell and had become important one of public health problem year, not only influences patient's physical and mental health and viability, increases its pain
Bitter and burden, increases the working strength of medical worker, it is also possible to cause doctor-patient dispute.
Health education is the important composition form prevented Aged In-patientss and fallen, and purpose mainly improves its anti-tumble
Knowledge, strengthen the conviction of anti-tumble, promotion slowly gets up, leans on crutch, handrail, the anti-tumbles such as on-slip shoes, reinforcement nutrition
Healthy behavior, and implement non-slip mat, warning sign, cleaning sundries etc. and improve the measure of environment, to reduce the generation of tumble.
But numerous due to causing the factor fallen, especially gerontal patient often integrates a variety of diseases and symptom, adds
Physical function decline, cerebral function degenerate and recognize cured psychological characteristics, gerontal patient can not fully understand, remember
With the intervening measure for performing effectively fall prevention, however it remains larger fall risk.134 of the investigation such as Ma Hongying fall
In patient, tumble reason is muscular strength deficiency person 76, dizziness and hyperpiesia or too low person 37；The investigation such as Wang Cuixia
In 11 people, suffer from 10 people of coronary heart disease, 8 people of high blood pressure, 9 people of cerebral infarction, 6 people of diabetes.In addition, 60~70 years old the elderly has centainly
Self-care ability, can take care of oneself or partial self-help completely, excessively high to own activity capability evaluation, trouble of being unwilling others, this
It is the reason of gerontal patient's tumble occurs.
Invention content
In view of this, the present invention, which proposes one kind, preventing patient's tumble device, allows patient passively to be helped, incline in body
Tiltedly when can intelligent-induction and play the role of balance body, effectively avoid patient and injured.
For achieving the above object, one kind of the invention prevents patient's tumble device comprising air bag, the peace
It is provided with air bag sensor on full air bag, the air bag sensor is connect with electronic controller, the electronic control
Device controls driving circuit and sends to start signal to gas generator, and gas generator is arranged in gas compartment, and the gas compartment is logical
Filtration core is connected to air bag.
The air bag sensor receives tilt signals, reaches the angle of inclination of setting, and air bag sensor is to electricity
Sub-controller sends out signal.
Sodium azide or ammonium nitrate are housed in the air bag.
Signal discrimination circuit is provided on the air bag sensor, signal discrimination circuit differentiates electricity by signal amplitude
Road, signal width differentiate that circuit and useful/garbage signal differentiate circuit three parts composition,
The air bag sensor is magnetoelectricity acceleration transducer, and air bag sensor is filled using falling weight impact test
It sets and corrects its induction susceptibility to adjust, discharge tup, when with rubber face percussion, the air bag being mounted on above tup senses
Device experiences impact acceleration, and different drop heights correspond to different acceleration, adjust rubber thickness, change signal width, and adjustment is dropped hammer
Highly, change signal amplitude.
The air bag is made of poly- phthalein amine fabric after vulcanizing treatment, and air bag inner wall is coated with coating material
Material.
The gas generator is gaseous type gas generator.
The present invention can allow patient passively to obtain external force support, avoid falling because of factors such as disease, medications.
Tumbler is received the signal that body inclination will fall by air bag sensor, as long as reaching defined intensity,
Sensor, that is, generation acts and sends out signal to electronic controller.After electronic controller receives signal, with its original storage signal
It is compared, if reaching airbag deployment condition, starting letter is sent to from gas generator of the driving circuit into air bag component
Number.Gas generator is connected to pilot gas propellant after signal, generates bulk gas, and air bag is entered after filtering and cooling, is made
Air bag breaks through the rapid expansion of liner within the extremely short time, forms elastic air cushion in the body of patient, and leak, shrink in time,
Impact energy is absorbed, to be effectively protected human body, injury is made it from or mitigates extent of injury.
Air bag mainly applies on automobile at present, and related data has used for reference automobile air-bag system.Air bag
System is known as SRS, and air bag is made of with rubber lined unique fabric nylon, is filled with harmless helium when work.
This patent is activated by an air bag sensor, and the air bag sensor is for monitoring that patient body inclines
Oblique angle.When cutting gradient arrival to a certain degree, air bag starts to inflate, and safety inflated takes around 0.03 second.Safety
Air bag can be inflated particularly significant at a very rapid rate, this can ensure that air bag can be in time and prevent when patient falls
Patient is directly hit on the ground.There are sodium azide (NaN3) or ammonium nitrate (NH4NO3) substance in air bag.When patient's body
Igniter when body tilts to a certain extent in air bag can open rapidly air bag, these substances can occur rapidly point
Solution reaction, generates bulk gas, is full of air bag.If it is high to cut oblique angle changing rate, needs to start air bag, then will put combustion gas
The instruction of capsule passes to gas-bag system.This namely requires air bag system that can accurately incude tumble thing occurred
Therefore；And human brain can be imitated, differentiates whether air bag needs to be unfolded according to actual inclined degree, there is certain flexibility；
And patient's adjustment air bag appropriate of the different bodily forms can be directed to.
Magnetoelectric sensor may be mounted at any position on clothes, as long as the gradient of patient is enough that patient is caused to fall
, trigger signal will be sent out to air bag, deployment balloon protects human body.The signal discrimination circuit of sensor is by three
It is grouped as:Signal amplitude differentiates circuit；Signal width differentiates circuit；Useful, garbage signal differentiates circuit.By to collision alarm
Multi-faceted differentiation is carried out, the tilt signals that control device obtains can be made more comprehensively, the ignition control sent out is more acurrate, to really
The air bag that ensures safety is unfolded in the case of necessary.How to obtain stable impact acceleration signal is research；The key of sensor,
And ensure that sensor accurately obtains the key of collision alarm.Magnetoelectricity acceleration transducer is adjusted using falling weight impact test device
Its induction susceptibility of whole correction.Tup is discharged, when with rubber face percussion, the acceleration or magneto-electric that are mounted on above tup sense
Device will experience impact acceleration.Different drop heights correspond to different acceleration；Rubber thickness is adjusted, signal width can be changed；Adjustment
Signal amplitude can be changed in height of the fall.
This tumbler device, when encountering fortuitous event, meeting instantaneous expansion alleviates the effect of impact force at inflatable balloon-like
It is 5 times of traditional tumble-preventing device safety coefficient；First, area can effectively reduce greatly the shaking of head and neck, second is that air bag
Have certain reaction force when expansion, can reduce that fracture of rib, internal organs that patient is susceptible to be impaired and bruise etc. is existing
As realization avoids 60% or more the accident because of air bag bullet wound cervical vertebra.It is a Gospel for children old man.
Beneficial effects of the present invention are：
1, patient is allowed passively to be helped
2, in body inclination can intelligent-induction and play the role of balance body.
