Detailed description of the invention
Below, in conjunction with accompanying drawing, the arm bending of the present invention is limited device to be described in detail.
The arm bending of the present invention limits device, and its main thought is, limits patient by limiting arm bending degree
The scope that can movable arrive of hands, give the freedom of movement that patient is certain, but patient can not be made to reach, and head arrange intubates, and keeps away
Exempt from tube drawing to occur.The repulsion of the second sleeve is realized by the restriction to the further arm bending of patient by coil.Bending
Degree is reflected by capacitance.If additionally, patient is in restless state, then limiting the arm bending of patient；When patient's
During the too fast bending of arm, then judge that patient is in restless state, repel the second sleeve by coil, limit the curved of patient's arm
Bent.Whether restless judgement, is mainly judged by the pace of change of capacitance, when the pace of change of capacitance is more than predetermined
During value, it is considered as patient and is in restless state.
The arm bending of the present invention limits device, comprising: first sleeve the 10, second sleeve 20, coil 30, control list
Unit, coil driver, capacitor, capacitive detection circuit.
First sleeve 10 includes periphery wall 11 and internal perisporium 12.Periphery wall 11 and internal perisporium 12 are spaced with preset distance, shape
Become to accommodate space.Second sleeve 20 is inserted in the receiving space of the first sleeve 10.
Second end of the second sleeve 20 extends beyond the second end of the first sleeve 10, and the second sleeve 20 is formed with Magnet
21.Magnet 21 can be formed in the first end of the second sleeve, it is also possible to is formed in the part near the first end or middle part, former
It is that Magnet 21 is the best the closer to coil 30 on then.Magnet 21 can be the annular magnet of whole cincture second sleeve 20, it is possible to
It is the symmetrically arranged multiple Magnet of circumference around the second sleeve, as long as all the magnetic pole of Magnet points to coil 30, namely
Saying, captivation or repulsive force between Magnet 21 and coil 30 are maximum, and the magnetic line of force direction of two magnets is consistent or parallel.The
The bottom accommodating space of one sleeve 10 is provided with spring 13, and the first end of spring 13 is connected with the bottom accommodating space, and second
End is connected with the first end of the second sleeve 20, and the i.e. second sleeve is connected to accommodate space bottom by spring.Coil 30 arranges
First end of one sleeve 10, can be formed in the outside of the first sleeve, it is also possible to be formed in periphery wall 11, or inner circumferential
In wall 12, but preferably it is formed at outside the first sleeve 10, and at its outside protective mulch.
The periphery wall 11 of the first sleeve 10 constitutes the first pole plate of capacitor, and internal perisporium 12 constitutes the second pole of capacitor
Plate, can be specifically that periphery wall 11, internal perisporium 12 are made up of metal, or electroplate in the above or be coated with metal level.Second
Sleeve 20 is configured to can be inserted into the electrolyte between the first pole plate of capacitor and the second pole plate, to change the electric capacity of capacitor
Value.Second sleeve 20 can be metal material, it is also possible to be include metal cladding or its wall in be provided with iron core, preferably
Two sleeves 20 are the metal level arranged around it.Also having a kind of situation, Magnet 21 is electric magnet, i.e. as with coil magneticaction
Magnet, again as the electrolyte of capacitor.
First pole plate and second pole plate of capacitor are respectively connecting to capacitive detection circuit；Capacitive detection circuit is used for detecting
The capacitance detected also is sent to control unit by the capacitance of capacitor；Control unit control coil drive circuit makes coil
Energising and produce and there is the magnetic force in predetermined strength and direction.
Capacitive detection circuit is prior art, repeats no more here.Control unit can be realized by single-chip microcomputer.
Make when the arm bending of user the second sleeve to first sleeve contract motion time, as the electricity of capacitor
Second sleeve of medium, owing to inserting in capacitor, changes the capacitance of capacitor, when capacitance detecting value reaches predetermined value, controls
Elementary control line circle drive circuit so that coil electricity and produce the magnetic pole phase of one end of the close described coil with described Magnet
The magnetic force scolded, limits the contractile motion of the second sleeve, thus limits the further bending of arm.
Control unit can connect alarm device, such as buzzer, warning lamp, or connection has wireless module, by wireless
Module is to server or nurse station generation alarm signal, and while limiting patient's arm motion, the very first time notifies nurse,
Make reply further.
During use, first the arm bending of the present invention is limited device and be enclosed within the upper arm of patient so that arm bending limits
First end of device is against at the axillary fossa of patient, and the second end of the second sleeve is beyond the ancon predetermined length of patient.When patient is curved
During bent arm, forearm curves inwardly, and oppresses the second end of the second sleeve so that the second sleeve shrinks in the first sleeve；Now,
The electric capacity of the capacitor making pole plate respectively with the periphery wall of the first sleeve and internal perisporium can be changed as dielectric second sleeve
Value, the capacitance of this capacitor is detected by capacitive detection circuit, and when exceeding predetermined value, control unit control coil drives electricity
Road so that coil produces the power of the close magnetic pole repelling described Magnet, stops arm to bend further.Another situation,
When arm aggressive bend, capacitance drastically changes, and when pace of change exceedes predetermined value, the most whether arm bends to pre-
Determining degree, all judge that patient is in restless state, coil produces repulsive force, stops the second sleeve to shrink further, i.e. stops hands
Arm bends further.
It is that patient has reserved certain arm bending space that the arm bending of the present invention limits device, is also prevented from arm simultaneously
Bend to be enough to the degree of tube drawing, while to patient's humanized nursing, prevent the generation of tube drawing accident as much as possible.
