The specific embodiment

Now, describe the present invention in conjunction with Figure of description and embodiment.

As shown in Figure 1, be the sketch map of wearable phototherapy device of the present invention.

Among Fig. 1, on the flexible body of making such as mylar or polyimide material, be provided with and many pad and lead formed flexible PCB, the two ends of LED respectively with every pair of pad in positive terminal pad and negative terminal pad be electrically connected, though, LED arranges according to regular hexagon among the figure, but LED also can adopt other forms to arrange, such as rectangle permutation, circular permutation etc., LED on the circuit board all is connected in parallel, drive by the LED driving device, the LED driving device can directly be a battery, or pulse generator.Preferably, can be that pulsewidth can synthetic pulse generator, like this, can adjust the power of LED by adjusting pulse width.

Before the patient uses therapy equipment among Fig. 1, need cut out flexible PCB according to the shape in affected part, like this, when using this therapy equipment, align as long as will install with the affected part, just can not avoid irradiation injury effectively to the unnecessary irradiation of perienchyma.

Fig. 2 is an alternative embodiment of the invention.

Among Fig. 2, whole flexible PCB is made up of a plurality of circuit unit shown in Figure 3 splicings.Each circuit unit is orthohexagonal; Each orthohexagonal circuit unit comprises seven pairs of pads, the wherein a pair of center that is arranged at orthohexagonal circuit unit, and all the other six pairs of pads equate with the distance at described center and open with identical angle intervals with respect to described center.Unit and unitary joint portion are for being connected projection 30, when the connection projection 30 of two adjacent circuit units 10 is superimposed together, with the conduction gim peg, such as peg, insert inner surface and have among the anodal via hole 31a and negative pole via hole 31b of conductive layer, thereby with two unit machineries be electrically connected.Here need to prove, all LED 20 on each circuit unit 10 are connected in parallel, the positive pole of LED20 on each circuit unit 10 is electrically connected with positive terminal pad 41, all positive terminal pad 41 of this circuit unit 10 are electrically connected with anodal via hole 31a by the lead (not shown) that stamps on circuit unit, in like manner, the negative pole of all LED 20 and negative terminal pad 42 are electrically connected, and all negative terminal pad 42 are electrically connected with negative pole via hole 31b by lead.

Like this, the patient just can select to connect some circuit units according to the shape in affected part, thereby forms and the corresponding circuit of affected part shape.

It is pointed out that here the electrical connection between the circuit unit is not limited to being connected projection and conducting electricity gim peg shown in the figure with mechanical connection, can also select other modes, such as inserting mode, snapping mode etc. are as long as can finish the electrical connection and the mechanical connection of adjacent cells.

For the light that LED is sent shines the affected part uniformly, can also lens unit be set on circuit unit, as described in Figure 4 and 5, lens unit comprises lens mount pad 50 and lens 60, lens 60 are convex lens.The position of lens 60 is corresponding with the position of each LED respectively, be positioned at LED directly over.Lens unit can be a circle as shown in FIG., also can be and the corresponding hexagon of circuit unit.Each lens can be mounted in the branch solid on the lens mount pad, and all are supported on the lens on the lens mount pad also can be an integral body.The lens mount pad can be integrally formed with its lens that supported, and also can form respectively.On the flexible body of lens mount pad attached to circuit unit, can be bonding by binding agent, also can be by installing hole being set on flexible body, the insertion foot being set accordingly, fixing the lens mount pad with inserting in the foot insertion installing hole in lens mount pad lower end.

In like manner, also lens unit can be set on the LED of the therapy equipment shown in Fig. 1.

For the ease of using, phototherapy device of the present invention can be attached on the fabric, and this fabric has bindiny mechanism, such as button, and slide fastener, thread gluing, buckle or the like is fixed in phototherapy device in patient's affected part.Like this, in treatment, do not influence the patient and carry out other activities, thus anxiety and anxiety can reduce patient treatment the time.

LED of the present invention can be infrared, blue streak or ultraviolet LED.

Fig. 6 is circuit theory diagrams of the present invention, and each LED 20 is connected in parallel, and is driven by LED driving device 70.

Because wearable phototherapy device of the present invention adopted LED as light source, and array of source is fixed on the flexible printed circuit board, and volume reduces greatly, and flexible body is fixed on whole therapy equipment on the patient's body by the connecting device of tissue layer.And the patient can make it corresponding with the shape in affected part according to the shape of affected part cutting or splicing therapy equipment, like this, maximum possible avoid irradiation damage to perienchyma.And its volume is little, and this instrument is convenient to move and is portable.The patient is can be at home own or dress this therapy equipment by the household, perhaps the patient is after first goes to hospital to be adjusted the power of therapy equipment according to patient's situation by doctor or professional and choose LED unit in the array of source according to the skin area that the patient need treat, patient just needn't go to hospital specially again, can be at home or office treat, saved patient's time.
