Description

Light quantum treating instrument for blood

The present invention is a kind of medical apparatus and instruments of using ultraviolet radiation blood.

The prior art of this technical field, at China's " patent of invention bulletin " the 8th volume, " light quantum treating instrument for blood " announced for No. 41, application number 92100563.6, it is characterized in that at utility model patent " blood therapeutic equipment ", improve on the basis of the patent No. 88209538.2, adopted micro computer to control automatically, increased detecting function radiation blood light intensity.The weak point that these two kinds of types exist is that the console model volume is big, noise big, the adopting quartz glass cost of container is expensive, and disinfection is difficult for carrying out, and more can not disposablely use.

The objective of the invention is automatically on the basis of control, to dwindle whole apparatus volume, also correspondingly simplify and improve light shielding device and oscillation device at above-mentioned micro computer, and the disposable Blood container after the improvement of the standard of employing transfusion bags.

The present invention mainly forms casing by panel, door, back plate, left plate, right plate, median septum, lamina tecti, lower clapboard, in light source, light shield device and oscillation device are housed, and mix disposable Blood container composition.

The present invention compared with prior art its advantage is one times of volume-diminished, weight saving, adopts disposable Blood container to clean, and also can avoid cross infection.Use in the place that is particularly suitable for no conditions for sterilization such as plateau, outlying district, field army.

Elaborate below in conjunction with accompanying drawing:

Fig. 1 represents front elevational schematic of the present invention.

Sketch map is looked in the left side of Fig. 2 presentation graphs 1.

The A of Fig. 3 presentation graphs 2 is to the local schematic top plan view of light shield device.

Fig. 4 represents the generalized section of facing of Blood container.

The schematic top plan view of Fig. 5 presentation graphs 4.

Profile of the present invention is rectangular solid figure among Fig. 1 and 2, back plate 6, median septum 11, lamina tecti 24, preceding light barrier 25 and lower clapboard 32 are housed between left plate 7 and right plate 9, panel 1 is equipped with in the front, on and off switch 2, fluorescent tube starting switch 3, charactron 12 and button 13 also are housed on it, the automatic control apparatus spare of micro computer is equipped with in its inside, and four footing 14 are equipped with in the bottom.Door 4 is equipped with in the front.Be shaped on passage 5 on the plate 6 of back, central upper portion is equipped with little exhaust fan 8.

Two supports 21, fluorescent tube 22 and reflection shield 23 are equipped with in the inboard of the central upper portion between left plate 7 and right plate 9.

Dark slide 10 is housed on median septum 11, small machine 19 is housed below driving pulley 20, the rope 26 and, median septum 11 by movable pulley 27.Driving pulley 20 be tightly packed in small machine 19 the axle on become drivewheel, be contained in hole 34(Fig. 3 by movable pulley 27) another side, but be screwed rotation on median septum 11.Driving pulley 20 and all be shaped on groove on the movable pulley 27 is loaded onto rope 26, and this forms light shield device.

Pillar 15, connecting rod 16, eccentric shaft 17, disk 18 and rotating disk 30 are housed on lower clapboard 32.Small machine 31 is equipped with in the bottom of lower clapboard 32.Rotating disk 30 is tightly packed on the axle of small machine 31.Disk 18 lower edge are equipped with eccentric shaft 17, and are rotatable.One end of connecting rod 16 is contained on the pillar 15 with screw, and the other end is contained in the edge of disk 18, and connecting rod 16 can be swung, and this forms eccentric oscillation component.

Dark slide 10 1 ends are shaped on screwed hole among Fig. 3, load onto two screws 33, and rope 26 is fixed on the dark slide 10.The center of median septum 11 is shaped on hole 34, and block 35 also is housed on it.

The center, Blood container 29 upper strata of Fig. 4 is shaped on glass support circle 36, is stained with glass 37 in it.

Blood container 29 1 sides of Fig. 5 are shaped on air intake 39 and blood transfusion port 40.

Best way of the invention process is that panel 1 adopts the insulation board machine to add to form.Door 4, back plate 6, left plate 7, right plate 9, median septum 11, footing 14, support 21, lamina tecti 24, front apron 25 and lower clapboard 32 all adopt 1～1.5 millimeter steel or aluminium sheet welding assembly to form, also can be made into frame structure, earlier weld framework, tumble in metallic plate again with angle iron.Float fan 8 adopts standard component.

Dark slide 10 and reflection shield 23 will be stamped to form with 0.5～1 millimeter aluminium sheet.Quartz burner adopts the high voltage mercury lamp of centre wavelength 365nm, power 125W.

Rope 26 adopts finer wire.Drivewheel 20 and follower 27 adopt aluminium bar, and the center car has through hole, and the outside car has half slot, can adorn rope 26.

Pillar 15, connecting rod 16 eccentric shafts 17, disk 18 and rotating disk 30 all adopt the aluminium machine to add and form.

Blood container 29 last slice and on glass support circle 36, adopt medical soft polychloroethylene once injection molded, the flexible plastic tube hot pressing with following sheet edge 41 and air intake 39 and blood transfusion port 40 is integrated again.Last slice center is embedded with glass 37, adopts the good glass of ultraviolet ray transmissivity to make.The profile of Blood container 29 is made circle or ellipse or rectangle.

Switch power supply switch 2 during operation is connected fluorescent tube starting switch 3 again, and the handle 28 that pulls the door open is placed on the disk 18 with the Blood container 29 that is filled with oxygen blood 38 is housed, close the door 4, restart automatic control button 13, after irradiation of blood finishes, dark slide 10 is blocked hole 34, opens the door 4 again, takes out Blood container 29.
