Preferred embodiment is described
Treatment table as shown in Figure 1 has the top for the prostrate platform of patient.
A supporting plate 10 is above the waist arranged at the top of platform, and this supporting plate 10 extends between the side bearing 12 of guide groove sample.Guide groove sample side bearing 12 extends to the total length of treatment table always, but in use, is supporting patient's upper part of the body supporting plate 10 above the waist and keeping motionless." above the waist " be meant the position that the health waist is above.Guide groove sample side bearing 12 extends in the bottom of supporting plate 10 above the waist, and includes the guide rail 14 for roller 19 uses of lower part of the body supporting plate 18.
Lower part of the body supporting plate 18 have horizontal expansion and with the roller 19 of guide rail 14 engagement, this roller can slide with respect to upper part of the body supporting plate 10.In use, lower part of the body supporting plate supports patient's the lower part of the body." lower part of the body " is meant the waist and the following position of waist of health.
Has handle 28 on the treatment table.These handles extend out from framework, and can vertically regulate along framework, and their structure as shown in Figure 4.The bearing 32 that has a plurality of support leading screws 34 in the bearing 30.Crank 36 is used for making leading screw to rotate in bearing.The helical pitch piece 38 of leading screw passes a groove 40 in the bearing 30 and stretches out, and handle 28 promptly is installed on this helical pitch piece.Obviously, rotate crank 36, helical pitch piece and handle just can vertically adjusting along treatment table.
According to Fig. 2 and Fig. 1, have a prestretched cylinder 72 to extend between frame 73 and the hold-down support 69, and hold-down support 69 link together with lower part of the body supporting plate.There is a treatment cylinder 46 to extend between upper part of the body supporting plate 10 and the lower part of the body supporting plate.Cylinder 46,72 is respectively via trachea 80,81 and 82,83 and pass electromagnetic air control valve 85,86 and 87,88 and come air feed.Hydraulic bjuffer 70 and 71 rate travels with the control treatment table are housed respectively on two cylinder assemblies.Controller 90 is given the control input end and the lock 100 output control signals of two valves of each draft cylinder 72.
Controller is accepted the input from strain gauge 42, and this strain gauge 42 is constantly measured the size of the pulling force on the braces that affacts the immobilized patients waist.Controller is also accepted the input from therapist's control station 58.On this control station, the treatment doctor sets the special parameter of the running of adjustment equipment as required, thereby is each patient customized treatment.
In case the treatment technician begins a therapeutic process, controller 90 is just accepted the signal from each parts, and adjusts every automatic function of equipment thus.Described each parts were monitored each stage of therapeutic process, and these parts comprise the spacing indicator on strain gauge 42, decompression and lax timer and cycle counter 57 and the mobile pallet 18.Controller output signal is given electromagnetic valve 85,86 and 87,88, controls to the air flow and the pressure of cylinder and cylinder locking mechanism 100.Monitor 113 produces continuously and is showing the form that writes down the treatment process.Modem 112 has a socket 114 and an interface 116, and socket 114 is connected to telephone system, and interface 116 is connected to outer computer.Controller is connected with memorizer 118 for this two-way communication.
According to Fig. 3, belt 44 is fixed along patient's pelvic area.Belt 44 has two parts 92 and 94, they with fillet belt 96 and 98 and belt fastener 100 and 104 around being fixed on one's body the patient.From belt extend out two drawstrings 106 and 108.As shown in Figure 1, drawstring 106 and 108 is connected on the belt tension dynamometer 42 by drawstring 110.In use, when table top separates, patient's waist is produced draw thereby lower part of the body supporting plate 18 slides backward and form pulling force.If desired, single belt can bring replacement with many root bark.
The design of belt is such, and promptly drawstring links to each other as follows with belt: the drawstring of back is located immediately on patient's the spinal column; The drawstring of front and the connecting portion of belt are positioned on the position of pelvis crista iliaca Ant sup (anterior superior spine of the Iliac crest of thepelvis).
The horizontal tension section of belt is designed to be that the fillet drawstring that relies on two parts 92 and 94 be fixed on belt realizes.
Obviously, also available chest braces is fixed on patient's the upper part of the body on the upper part of the body position of treatment table, but has been found that the patient can be more comfortable if there is not this fixture.Usually, he just can be more lax above the waist the time when the patient fixes it in the mode of independently holding handle on one's body the towing power of being added in because he feels exceeded he TL he can loose one's grip.The mode of this fixedly upper part of the body is an important security feature, and this makes patient's stopped treatment at any time.
When treatment, belt 44 is securely fixed on patient's the waist and pelvis as depicted in figs. 1 and 2 like that, and the patient holds handle 28 simultaneously.Belt links to each other with strain gauge 42 with 110 by drawstring 106,108, and these drawstrings are fixed on the belt, and extend out between patient's two lower limbs in the mode of " wearing diaper ", and they are adjustable, to be fit to each patient.The operator by control station 58 give controller 90 input therapeutic processes cycle-index, be added to the maximum pull on patient's lumbar vertebra control point and be each decompression of unit and the time span of loosening process with the second.
The technician presses prestretched starting button 55 and comes the begin treatment process.The starting of prestretched system makes controller 90 output signal to electromagnetic valve 87 and 88 and unclamp cylinder lock 100, and this makes 72 piston of prestretched cylinder stretch out.The piston movement speed of cylinder 72 is controlled with air mass flow, and the inflow and the delivery flow of air are measured.Hydraulic bjuffer 71 is fitted together with the prestretched cylinder, is beneficial to piston and obtains accurate moving.
When the prestretched cylinder promoted the frame 73 of strain gauge is housed, being added to patient's pulling force had on one's body just increased.One end of drawstring 110 links to each other with strain gauge, the other end be fixed on belt on and the drawstring 106 that extends out therefrom link to each other with 108.Drawstring 110 has been eliminated most sags through technician's initial adjustment.The mobile frame 73 that has promoted to have strain gauge of cylinder 72 makes its towing belt backward.The weight that acts on the patient on the treatment table stops the patient to move, and acts on patient's braces and the growth of hyperpelvic pulling force.
Acting on patient's pulling force on one's body measures with strain gauge 42.Strain gauge 42 sends to measured value controller 90 and monitor 113 continuously.The output of monitor is that unit is presented on the light emitting diode 59 of technician's control station 58 with the pound on the one hand, starts a charting device 60 that the treatment process is continued tracing record on the other hand.This recorder provides the HC hard copy of the following items of each therapeutic process: relation and cycle-index between pulling force, time, these two parameters.
In case prestretched is after stablizing on the basic tension level, controller just starts cylinder locking mechanism 100, makes prestretched cylinder and frame 73 lockings.In decompression and retraction process, the establishment of the control sequence of controller is for keeping the latched position of frame 73 with respect to mobile pallet 18.
The operator presses the system's control knob 56 on the control station 58 subsequently, all automatic functions of beginning starting device, make it begin to enter decompression process and start timer, and send three the tinkle of bells and remind the patient to hold handle 28 to fix above the waist the pulling force that will produce so that treatment-resistant cylinder 46 is promoted mobile pallets 18.The strain gauge frame that links to each other with belt, such as previously described, be link to each other with mobile pallet and be locked in should have locational.
In case press treatment button 56, controller 90 just start electromagnetic air valve 86 and 85 control flow into and flow out treatment cylinder 46 air so that this cylinder stretch, thereby carry out the stretched operation of a draft procedure as described below.
The traction table of standard can cause that usually the reflection flesh of muscle defends and spasm, thereby is worth limited or is not worth having proved aspect the discogenetic disease of treatment lumbar vertebra.In the spinal column axis of non-intervention before decompression method produces, this class disease be to move operating.
Have been found that by using described treatment table to apply to be the pulling force of logarithm, can avoid the reflection flesh of muscle to defend and spasm.In more detail, adopt the following method of operation, treatment table is evident in efficacy: to the starting stage of treatment, by increasing the separating force on the table top, make pulling force begin gently to increase from basic pulling force.Do like this and help loosening of patient, thereby can adapt to the pulling force that is applied, this success to treatment is very important.Preferably, this initial " slow start " will continue for 9 seconds, the increase of power can be the time once or quadratic function, pulling force rises to 50% maximum on the basic pulling force at most.Be that a pulling force is the logarithm stage that logarithm is increased to maximum pull subsequently, preferably make it reach maximum 60 seconds the time by the method that makes independently power on the table top be logarithm to increase.Maximum pull can be set at any value in 50～100 pounds of scopes, on average is set at 70 pounds.
Pulling force will increase at a slow speed by the logarithmic function rule, and its reason thinks to avoid treatment table to run into reactive muscle problem.
After decompression process finished, promptly in the retraction stage of treatment, it is lax linearly that pulling force is, and get back to basic state of tension with the control rate of programmed settings in advance.Preferably whole decompression and retraction process are 90 seconds.If pulling force is lax too fast, or is not to remain on the basic pulling force, the muscle problem of inducing reaction property once more then.Be reduced to basic pulling force linearly with a suitable slope, then can avoid the appearance of this problem.Under the basic pulling force through a rest stage after, just can repeat above-mentioned process.
Have been found that following time-pulling force function can produce the logarithm stage of a satisfaction.Have been found that such logarithm stage can make the malleation that is present in usually on each intercentrum be reduced to remarkable minus negative pressure (sucking).

MaxIn the terminal point moment in-logarithm stage, this moment, pulling force reached maximum.
For example, select that BTi is that 9 seconds, BTn are 15%, In is 8.5% and Ti
MaxBe 60 seconds, N
MaxBe 10, C is 1.06422, then equation becomes:
Exp(1.06422
N×Ln(9))=15％+(N×8.5)。
According to this logarithmic equation, drawn following pulling force-time relationship (coming the formation base pulling force) with 0%:
T=17.10 second when 50% maximum pull
T=20.98 second when 60% maximum pull
T=26.44 second when 70% maximum pull
T=33.91 second when 80% maximum pull
T=44.32 second when 90% maximum pull
After retraction stage began, in initial 5 seconds, pulling force reduced 5% of maximum pull, 10% of per then 2.5 seconds minimizing maximum pulls.
The suitable time is listed among Fig. 5 with forms mode value of thrust, and is drawn among Fig. 6.Wherein 0% pulling force has constituted basic pulling force.
Found that another energy provides the loaarithmic curve of satisfactory result at decompression phase:
Exp(N×Ln?K+Ln(BTi))=BTn+(N×In)
The definition of N, Bti, BTn and In is the same in the formula, and
K=Exp[(Ln?Ti
max-Ln?BTi)/N
max]。
Get BTi and be 9 seconds, BTn and be 15%, In is 8.5%, Ti
MaxBe 60 seconds, N
MaxBe 10 and K be 1.2089, the time of generation is listed in the table of Fig. 5 a value of thrust, and is drawn among Fig. 6 a.
Fig. 6 and Fig. 6 a show that 50% maximum pull has gone over to reach for three/a period of time at decompression phase.Studies show that, the pulling force that will be added on the lumbar vertebra in the mode that changes linearly along with the time continues to increase to 50% maximum pull value, this just will bring out reflection flesh defends, and reflection flesh to defend be can stop the lumbar vertebra body to reach to make required isolating of lumbar intervertebral disc and neuropore decompression.Yet have been found that, if that part of of the basic pulling force of representative above 0% to 50% is straight line on the pull-up curve, but it is close that its controlled rate of rise reaches the rate of increase of logarithmic time/tensile relationship of 50% maximum pull with can guarantee to have gone in 1/3rd in the decompression phase time time, and then decompression still can take place.That section from 50% maximum pull to maximum pull, the increase of power must be followed logarithmic function rule in time, to avoid the reaction of reflexive muscle.
When repeatedly applying when being enough to make the pulling force of waist structure decompression, in order to prevent reflexive muscle contraction (flesh is defended), middle the very important point at decompression phase is to have a cumulative controlled table top separating rate, and this is to guarantee to treat successfully to reach to make the patient comfortable necessary.
In case decompression timer 62 finishes the timing (being set at 40～60 seconds usually) of decompression phase, just notification controller starts electromagnetic valve 85 and 86, these two electromagnetic valves are controlled with the end decompression phase the air of inflow and outflow cylinder 46, and make mobile pallet 18 withdrawals.The air flow of programming Control and exhaust stream are in conjunction with the damping action that is combined in the hydraulic bjuffer in the cylinder assembly, the translational speed of arranging retraction stage mobile pallet 18 together.Through 25～30 seconds, the pulling force that acts on the belt is similar on the basic tension level that rolls back linearly between 20～24 pounds of scopes.
Although pulling force is preferably 25～30 seconds from the time that maximum is reduced to basic pulling force, also allow a shorter or longer turnaround time among a small circle.The short retraction time, tend to cause higher muscle response incidence rate under certain conditions; The long retraction time then makes patient's fatigue easily but can not significantly increase curative effect.
At the terminal point of retraction stage, removable supporting plate 18 lumps together with fixing supporting plate 10.If the pulling force that the prestretched system that this moment, strain gauge 42 recorded applies is above 26 pounds or be lower than 20 pounds, strain gauge 42 just signals to controller 90, cylinder lock 100 is unclamped and start electromagnetic valve 87 and 88, do suitable control with inflow and discharge to air, the pulling force that the prestretched system is applied is adjusted up or down as required, and making it be returned to static pulling force is 20 pounds foundation level.At this moment, controller starts locking mechanism again pulling force is remained on that level.If necessary, this is adjusted function and can work always, so that keep prestretched basis pulling force in each loosens the overall process in stage.In order to make drawstring unlikely lax between circulation, this point is absolutely necessary.Because allow pulling force to be reduced to zero, drawstring will relax.By the cooperative system that controller, table top location, strain gauge feedback, cylinder adjustment and locking mechanism constitute, leniently implement to adjust by programming usually, leave the patient alone to guarantee this automatic function, avoid reflex muscular to defend.
When treatment table is in retraction stage, and reached one predefined, when representing mobile pallet 18 with value of thrust that fixedly supporting plate was closed already, strain gauge 42 notification controllers start and loosen stage timer 62 (being made as usually 40～60 seconds).In the time of when mobile pallet and fixedly on the supporting plate closure, " closure " status lamp of a green is shinny to remind the technician, and simultaneously, the bell sound that controller sends a monophone can release handle with the prompting patient, until the ring signal that sounds once more three, end when representing another circulation beginning.Treatment circulation is loosened the stage by a decompression phase, retraction stage and one and is formed.
In therapeutic process, if patient's slippage handle or braces has unclamped and/or drawstring makes table top advance to its range, a red eye on the control station 58 is shinny, reminds the technician must adjust so that treatment table normally moves.In addition, if carry out prestretched adjustment result in the stage and make the prestretched frame be stretched over its travel limit loosening, this then will be difficult to adjust and obtain suitable basic value of thrust, controller just sends multiple acoustical signal and reminds the therapist must adjust the drawstring of pre-stretching device, keeps suitable basic pulling force with the stage between each circulation.
To sum up said, can see significantly that a treatment circulation continues about 90 seconds, about 40～60 seconds of the interval between the circulation altogether.To circulation carry out timing and the circulation between arranged to loosen the stage, this helps helping the patient to adapt to the strong pulling force of decompression phase, and helps alleviating the fatigue in the therapeutic process.
As shown in Figure 7, be returned to the cyclic process that basic pulling force forms so again from basic pulling force to maximum pull, in therapeutic process, repeat automatically, be generally 15 times by selected cycle-index.
After the last circulation of therapeutic process is finished, pulling force is got back to basic value, the air cock that controller is opened the prestretched cylinder makes the prestretched value be reduced to zero, close timer, make chronocyclograph reset to predefined numerical value, be generally 15, and make the state before all functions are returned to beginning, for next patient's treatment is got ready.Lock onto treatment table and an interval must be arranged between resetting fully from unclamping prestretched, to avoid treating cylinder and the prestretched cylinder shrinks simultaneously, because this will cause pulling force to discharge suddenly and evoke flesh and defend reaction.After all pulling force on the belt were eliminated, the therapist just can separate the patient with strain gauge, at this moment help the patient to remove belt again, gets off from treatment table.
Except can be by the autonomous release handle of patient negatively the stopped treatment process, controller also programmed settings two security functions limit the size that acts on patient's pulling force on one's body.Maximum pull is set at by the operator can not be above 100 pounds.This has just guaranteed that pulling force does not exceed therapeutic domain, and thereby avoids causing muscle contraction and/or soft tissue anxiety.If the pulling force that strain gauge 42 records has reached 100 pounds, controller 90 is locking treatment cylinder just, and the prevention pulling force further increases and remains on that level.
Pulling force is raised to more than 100 pounds and the level that locks onto 110 pounds if the patient pulls at handle, then strain gauge just signals to controller, and controller promptly cuts out whole system, table top is returned, make prestretched be returned to zero, the controller on and off switch lamp that repeats to glimmer, the expression security function starts.In this case, cyclic process just can not have been restarted, and only closes main power switch, has restarted another time therapeutic process.
The retraction speed that the front was described is set by the testing equipment of standard, and this equipment provides a constant resistance in retraction process.In treatment during the patient, especially near the terminal point of retraction stage the time, because organizational slack, pulling force often reduces easily more quickly.Owing to be provided with memorizer and modem section in this equipment, thereby greatly strengthened the operating parameter of remote monitoring decompression table and the ability of its working condition of observation and function.
