Embodiment
Below, the arm bending limits device of the present invention is described in detail with reference to accompanying drawing.
The arm bending limits device of the present invention, its main thought is to limit patient by limiting arm bending degree
Hand can the scope that arrive of activity, give the certain freedom of movement of patient, but patient can not be made to reach the intubation of head setting, keep away
Exempt from tube drawing.Limitation to the further arm bending of patient is realized by repulsion of the coil to second sleeve.Bending
Degree is reflected by capacitance.In addition, if patient is in restless state, the arm bending of patient is limited；When patient's
During the too fast bending of arm, then judge that patient is in restless state, second sleeve repelled by coil, limitation patient's arm it is curved
It is bent.Whether restless judgement, mainly judged by the pace of change of capacitance, made a reservation for when the pace of change of capacitance is more than
During value, it is considered as patient and is in restless state.
The arm bending limits device of the present invention, it includes：First sleeve 10, second sleeve 20, coil 30, control are single
Member, 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 with preset distance interval, shape
Into receiving space.Second sleeve 20 is inserted in the receiving space of the first sleeve 10.
Second end of second sleeve 20 extends beyond the second end of the first sleeve 10, formed with magnet in second sleeve 20
21.Magnet 21 can be formed in the first end of second sleeve or be formed adjacent to the part or middle part of first end, former
It is that magnet 21 is better closer to coil 30 on then.Magnet 21 can be a whole annular magnet around second sleeve 20, also may be used
It is the symmetrically arranged multiple magnet of circumference around second sleeve, if the magnetic pole of whole magnet points to coil 30, that is,
Say, the attraction 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 of the receiving space of one sleeve 10 is provided with spring 13, and the first end of spring 13 and the bottom of receiving space connect, and second
End is connected with the first end of second sleeve 20, i.e., second sleeve is connected to receiving space bottom by spring.Coil 30 sets the
The first end of one sleeve 10, the outside of the first sleeve can be formed in or formed in periphery wall 11, or inner circumferential
In wall 12, but the outside of the first sleeve 10 is preferably formed in, and in its outside protective mulch.
The periphery wall 11 of first sleeve 10 forms the first pole plate of capacitor, and internal perisporium 12 forms the second pole of capacitor
Plate, can be specifically that periphery wall 11, internal perisporium 12 are made up of metal, or plating in the above or covered with metal level.Second
Sleeve 20 is configured to can be inserted into the dielectric between the first pole plate and the second pole plate of capacitor, to change the electric capacity of capacitor
Value.Second sleeve 20 can be metal material or cored including being set in metal cladding or its wall, preferably
Two sleeves 20 are the metal level around its setting.Also a kind of situation, magnet 21 are electromagnet, i.e., as with coil magneticaction
Magnet, the dielectric as capacitor again.
The first pole plate and the second pole plate of capacitor are respectively connecting to capacitive detection circuit；Capacitive detection circuit is used to detect
The capacitance detected is simultaneously sent to control unit by the capacitance of capacitor；Control unit control coil drive circuit makes coil
It is powered and produces the magnetic force with predetermined strength and direction.
Capacitive detection circuit is prior art, is repeated no more here.Control unit can be realized by single-chip microcomputer.
When the arm bending of user make it that second sleeve is moved to the first sleeve contract, the electricity as capacitor
The second sleeve of medium is due in insertion capacitor, changing the capacitance of capacitor, when capacitance detecting value reaches predetermined value, control
Elementary control line circle drive circuit so that coil electricity and produce the magnetic pole phase with one end of the close coil of the magnet
The magnetic force of reprimand, the contractile motion of second sleeve is limited, so as to limit the further bending of arm.
Control unit can connect warning device, such as buzzer, warning lamp, or be connected with wireless module, by wireless
To server or nurse station alarm signal occurs for module, while patient's arm motion is limited the very first time notify nurse,
Make further reply.
In use, the arm bending limits device of the present invention is enclosed on to the upper arm of patient first so that arm bending limits
The first end of device is against at the armpit of patient, and the second end of second sleeve exceeds the ancon predetermined length of patient.When patient is curved
During bent arm, forearm curves inwardly, and oppresses the second end of second sleeve so that second sleeve is shunk into the first sleeve；Now,
The electric capacity for the capacitor for making pole plate with the periphery wall and internal perisporium of the first sleeve respectively can be changed as dielectric second sleeve
Value, the capacitance of the capacitor detected by capacitive detection circuit, during more than predetermined value, control unit control coil driving electricity
Road so that coil produces the power for the close magnetic pole for repelling the magnet, prevents arm from further bending.Another situation,
When arm aggressive bend, capacitance drastically changes, when pace of change exceedes predetermined value, no matter now arm whether bend to it is pre-
Determine degree, all judge that patient is in restless state, coil produces repulsive force, prevents second sleeve from further shrinking, that is, prevents hand
Arm is further bent.
The arm bending limits device of the present invention has reserved certain arm bending space for patient, while is also prevented from arm
The degree for being enough tube drawing is bent to, while to patient's humanized nursing, prevents the generation of tube drawing accident as much as possible.
