Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Figs. 1-5, a kind of the elderly's clearing lung-heat expectoration device, including wearable unit, vibration unit and suction sputum unit；Institute
The wearable unit stated includes positioning plate 1 and the package clothing 2 around human chest；The left and right ends for wrapping up clothing 2 are connected by velcro
It connects；The upper and lower ends of package 2 lateral surface of clothing are uniformly fixed with multiple female threads 3 respectively；The upper and lower ends of positioning plate 1 be mounted on
The sub-buckle 4 of 3 corresponding matching of female thread；1 rear end of positioning plate is provided with protective bag 5；It is fixed on the upside of 5 upper end of protective bag and positioning plate 1 to connect
It connects；Several bag of chamber 6 is uniformly sewed in protective bag 5；Shear thickening liquid is filled in bag chamber 6；Front and back is run through and is set on positioning plate 1
It is equipped with multiple threaded holes 7；The vibration unit includes the installing pipe 8 being threadedly coupled with threaded hole 7；Front is solid in installing pipe 8
Dingan County is equipped with electromagnet 9；9 rear end of electromagnet is fixedly connected with pressure spring 10；The rear end of pressure spring 10, which is fixedly connected with, taps column 11；It strikes
The front center for hitting column 11 is vertically installed with the adjusting rod 12 of irony；The suction sputum unit includes tool stand 13 and negative pressure pump
14；13 upper end of tool stand is equipped with suction sputum box 15；The suction end of negative pressure pump 14 is connected to 15 top of suction sputum box；15 top of suction sputum box
It is communicated with sputum aspirator tube 16；The head periphery of sputum aspirator tube 16 is uniformly connected with rubber tube 17；Magnetic powder 22 is filled in rubber tube 17；It adjusts
Pole 12 is threadedly engaged with adjustable column to be connect；Adjustable column front end is fixedly installed with permanent magnet 18；Control is installed on tool stand 13
Panel 19；The control circuit of electromagnet 9 is installed in control panel 19；It is provided on control panel 19 and adjusts pole button 20 and intensity
Knob 21.
In the use of the present invention, patient dresses package clothing 2, connection is clinged using velcro, package clothing 2 is made to fit in human body
Thoracic cavity position, positioning plate 1 are fitted on package clothing 2 by snap fastener 3, and protective bag 5 is compressed in positioning plate 1 and package
Between clothing 2, the shear thickening liquid in bag chamber 6 does shape adaptive change, coincide and is bonded with the shirtfront of patient or back.It needs to shake
When dynamic expectoration, it is coupled vibration unit and suction sputum unit carries out clearing lung-heat expectoration.The filling of shear thickening liquid in bag chamber 6 is thick
Degree, should be by modes such as actual tests, and when receiving to hit to a certain degree, it is thick that the thickness of consolidation zone is greater than filling for control
Degree, when guaranteeing that hitting vibration occurs, the shear thickening liquid of filling can all solidify, preferably transmitting vibration, avoid excessive
Normality under shear thickening liquid reduce vibration transmitting.
Positioning plate 1 can select according to the actual situation model and quantity appropriate to be pacified there are many big ting model
Dress.Installation site appropriate is selected, is connected and fixed positioning plate 1 using sub-buckle 4 and female thread 3.Match respectively in multiple threaded holes 7
Installation vibration unit is closed, pipe 8 is rotatablely installed, makes the percussion column 11 of each position that can squeeze contact protection bag 5, Primary regulation is complete
Cheng Hou, later use is substantially without adjusting or only needs suitably to adjust.When being vibrated, after electromagnet 9 is powered, magnetism is utilized
It is attracting with adjusting rod 12, it taps column 11 and is detached from protective bag 5, and compression press spring 10, electromagnet 9 power off at once, utilize pressure spring 10
Potential energy accelerates knock protection bag 5, and energization power-off repeatedly, then tap column 11 quickly repeatedly can cause to tap to protective bag 5
Vibration.
When impinging upon in protective bag 5 of the quick high frequency of column 11 is tapped, the shear thickening liquid in region is impacted rapid solidification,
The part being bonded at this time with human body still keeps good fitting shape, and vibration is uniformly transmitted to thoracic cavity position, causes inside
The vibration of lung and respiratory tract assists expectoration.
Such as the last dys-expectoration of gerontal patient, endotracheal suction (ets) is carried out using suction sputum unit, sputum aspirator tube 16 is placed in and is suffered from
Person is intratracheal, and can extend to lung orientation, and in vibration unit work, the magnetic force of generation influences the magnetic powder in rubber tube 17
22, cause rubber tube 17 to move, sputum sticky around can be carried out the movement such as to pull, convenient for utilizing negative pressure absorbing sputum.Together
When to it is intratracheal nerve and respiratory mucosa stimulate.Sputum aspirator tube 16 enter when, rubber tube 17 itself is softer, be easy into
Air entering flue injures smaller.
If permanent magnet 18 is installed in 12 front end of adjusting rod, the reversal of magnetism of electromagnet 9 can power-assisted generation absorption and repulsion work
With drive taps 11 percussion vibration of column.
If discomfort needs compressing alleviation occurs in chest position, rotatably mounted pipe 8 drives percussion column 11 to be squeezed
Pressure increases the extruding of 10 pairs of percussion columns 11 of pressure spring, makes to tap at the compressing patient's discomfort of column 11.Similarly positioned using above-mentioned extruding
Mode carries out pressurization fixation to wound circumference, in vibration, does not start electromagnet 9 herein, preferably protects wound.
Using the big ting model of vibration unit difference and be coupled the difference and electromagnet 9 of position and quantity
The difference of installation number and position, while cooperating the regions curing property of shear thickening liquid, the wound site of patient can be avoided.
It can also will be not involved in regions curing transmitting vibration, reduce the biography directly vibrated in the corresponding shear thickening liquid discharge of wound site
It passs.
Tune pole button 20 and brightness knob 21 on control panel 19 and the magnetic pole for regulating and controlling electromagnet 9 and magnetic field are strong
Degree.
The coefficient of elasticity of pressure spring 10 is bigger, then vibration device can shorten accordingly.
