Description

A kind of treatment head of Phototherapeutic instrument

This utility model relates to a kind of treatment head of Phototherapeutic instrument.

Phototherapeutic instrument utilizes visible light, the infrared light biological effect that heat effect produced to biological tissue of human body, and by control biological tissue be heated the optical radiation power density power and the irradiation time at place, reaches the purpose to disease treatment.This instrument is made up of hand-held optical therapeutic head and main frame (in establish minisize electromagnetic pump and water tank), and the optical therapeutic head is made up of light source and optical focusing system and light-guide device, cavity etc.Chinese invention patent description CN1099306A discloses a kind of Phototherapeutic instrument, and wherein the bromine tungsten filament lamp in the treatment head is contained on the magnetic holder, and the rear of bromine tungsten filament lamp is a homocentric pencil of rays reflector, and its rear is a water storage case; The place ahead of bromine tungsten filament lamp is a transmission-type high order aspheric surface lens light gathering system, and condenser system is contained in the lens barrel, is annular cooling bath on every side, and Z-shaped water channel is arranged in the cavity, picks out water nozzle and inserts water tank through water pipe.This treats a light path complexity, and the luminous energy loss is big, cools off fully inadequately, and passage stops up easily, and contact reliability is poor, and difficulty of processing is big, and volume is big, deal is heavy, and operator's susceptible is to tired.

The purpose of this utility model is to provide a kind of light channel structure simple, the treatment head of good cooling results.

For achieving the above object, the treatment head of this utility model Phototherapeutic instrument comprises entity light guide, bromine tungsten filament lamp, cavity, and bromine tungsten filament lamp is installed in the cavity, and said entity light guide light-receiving end face is near bromine tungsten filament lamp; Be provided with mouse cage shape water of radiation circulation road in the said cavity, the intake-outlet of this passage and has the water-cooled body of water inlet pipe and outlet pipe to be connected, and the electrode clamping plate are fixed on this water-cooled body; The lamp base of bromine tungsten filament lamp is installed in the metal lamp holder, and this lamp socket contacts with cavity.

Be provided with an inserts between the lamp base of said bromine tungsten filament lamp and the lamp socket, fastening with holding screw.

Technique scheme has following some characteristic: 1, allow entity light guide light-receiving end face be directly adjacent to the bromine tungsten filament lamp bulb as far as possible, simplified the light conducting structure, the power that increases bulb simultaneously is to 300W, and one can make Output optical power reach more than the 50W thus.2, adopt mouse cage shape water of radiation circulation road in the cavity, cooling water can evenly cool off whole heating cavity on the one hand, and cavity volume is dwindled greatly, weight saving, and passage is difficult for stopping up simultaneously, designs simplification, difficulty of processing descends, and material consumption is few.3, because the temperature of bromine tungsten filament lamp is very high, metal partly spread transmission around high temperature not only can reach along lead, and even more serious is promptly can make the lead oxidation in the short time, and influence electrically contacts, be fixed on the water-cooled body electrode clamping plate directly that counter electrode cools off, two kinds of drawbacks are readily solved simultaneously.4, bromine tungsten-arc lamp bulb is adopted metal lamp holder and be aided with can shading and can reduce the inserts of mechanical stress, whole lamp socket all is in the cavity water-cooled scope, has not only solved heat dissipation problem, avoids the lamp base explosion, and has simplified the bromine tungsten filament lamp technique for fixing greatly.

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1 is the treatment header structure sketch map of this utility model Phototherapeutic instrument;

Fig. 2 is that Fig. 1 is along A-A line cutaway view;

Fig. 3 is the lamp socket cutaway view of embodiment shown in Figure 1;

Fig. 4 is the cavity cutaway view of embodiment shown in Figure 1;

Fig. 6 is the cutaway view of Fig. 4 along the B-B line;

Fig. 7 is the cutaway view of Fig. 4 along the C-C line.

As seen from Figure 1, the treatment head of this utility model Phototherapeutic instrument comprises entity light guide 1, bromine tungsten filament lamp 2, cavity 3, and handle 4 is connected with cavity 3, and bromine tungsten filament lamp 2 is installed in the cavity 3, and entity light guide 1 light-receiving end face is near bromine tungsten filament lamp 2; Be provided with mouse cage shape water of radiation circulation road 5 in the cavity 3.Referring to Fig. 2, the intake-outlet of this passage 5 and have water inlet pipe 6 and outlet pipe 6 ' water-cooled body 7 be connected.Electrode clamping plate 8 are fixed on this water-cooled body 7, the end line 9 and 9 on the electrode clamping plate 8 ' connect low-tension supply.The lamp base of bromine tungsten filament lamp 2 is installed in the metal lamp holder 10, bromine tungsten filament lamp 2 is inserted in the cavity 3 lamp socket 10 is contacted with cavity 3.

Referring to Fig. 3, but be provided with a light blocking inserts 11 between the lamp base of bromine tungsten filament lamp 2 and the lamp socket 10, fastening by holding screw 12, like this, inserts both can be fixedly clamped lamp base on lamp socket, can reduce mechanical stress again, and unlikely lamp base breaks.

By Fig. 4, Fig. 5, Fig. 6, Fig. 7 as seen, the mouse cage shape water of radiation circulation roads 5 in the cavity 3 are evenly distributed in the wall of chamber, and the two ends of cavity 3 are with capping 13 and 13 ' and be furnished with sealing ring and seal, and this lid can be with being threaded with cavity 3, and also available screw is fastening.Cavity 14 is placed bromine tungsten filament lamp.The water inlet 15 of mouse cage shape water of radiation circulation road 5 communicates with the water inlet pipe of water-cooled body, and outlet communicates with the outlet pipe of water-cooled body.

The treatment of a this utility model Phototherapeutic instrument cooling principle is as follows: the water inlet pipe 6 of cooling water in water-cooled body 7 flows into the water inlet 15 of mouse cage shape water of radiation circulation road 5, again through the water of radiation circulation road to capping 13 ' direction flow, another water channel of turning back again flows to the direction of capping 13, it is mobile so to turn back, and flows into the outlet pipe 6 ' interior outflow of water-cooled body 7 at last from the outlet of mouse cage shape water of radiation circulation road 5.
