Abstract
The utility model relates to a medical appliance, particularly a fiber-optic needle for irradiating human blood by using laser with lower energy. The utility model is mainly provided with transparent cavities which are respectively and tightly matched with the rear end of a puncture needle tube and the rear shaft of the fiber-optic needle through a front wall hole and a rear wall hole which are concentric, while optical fibers are hung in the transparent cavities and the puncture needle tube. Consequently, the utility model can ensure that the front end of the optical fiber is positioned in the blood of blood vessels and can effectively carry out the irradiation therapy.
Description
This utility model relates to a kind of medical apparatus, especially refers to the optical fiber pin that the low-energy laser irradiation blood of human body is used.
As everyone knows, on the clinical medicine, extensively utilize the irradiation of light quantum to the human vas inner blood, the treatment various diseases especially utilizes low-energy laser, as: the irradiation of He-Ne laser, semiconductor laser etc.
At present, the optical fiber pin that the low-energy laser irradiation blood of human body is used, wherein the direct tight fit of optical fiber or with binding agent be bonded in the puncture needle tubing in, the interior no blood back passage of the needle tubing that promptly punctures, just judge that with operator's experience the bevel needle of puncture needle tubing is whether just in time in human vas, blindness can occur inevitably, even the mistake of treatment occur.
In view of this, the purpose of this utility model is at above-mentioned defective, and a kind of transparent chamber that leaves the slit passage and show blood back between optical fiber and puncture needle tubing is provided, and the bevel needle of puncture needle tubing is in the human vas.
The purpose of this utility model is achieved in that it comprises puncture needle tubing and optical fiber, also be provided with it concentric before cinclides and back cinclides fit snugly in transparent chamber on the rear end axle of puncture syringe rear end and optical fiber pin respectively, and optical fiber is suspended in the transparent chamber and the puncture needle tubing in.
Above-mentioned transparent chamber is lucite or plastic flexible pipe.
The equal coating adhesive in the close-fitting outer face of rear end axle of above-mentioned transparent chamber and puncture needle tubing, optical fiber pin.
Because adopt such scheme: the front end that can guarantee optical fiber is in the blood of blood vessel, carries out effective irradiation treatment.
Below in conjunction with drawings and Examples this utility model is further specified.
The structural representation of Fig. 1 this utility model exemplary embodiments.
Among the figure: 1, puncture needle tubing 11, bevel needle 2, transparent chamber 3, optical fiber 31, rear end axle 32, sleeve pipe
Present embodiment comprises puncture needle tubing 1, transparent chamber 2 and optical fiber 3, as shown in Figure 1, and wherein:
Puncture needle tubing 1 is the hollow rustless steel needle tubing that front end is bevel needle 11, belongs to prior art.
The rear end of optical fiber 3 (single or many optical fiberss) has a rear end axle 31 (thicker than optical fiber 3 section diameters), and the periphery of optical fiber 3 parts except that rear end axle 31 also can a sheathed sleeve pipe 32, to increase the rigidity of optical fiber 3, belongs to prior art.
Before transparent chamber 2 is, be respectively equipped with the cavity of concentric holes on the rear wall, usually make with lucite or plastic flexible pipe, hole on its antetheca closely cooperates with puncture needle tubing 1 rear end, and the rear end axle 31 of hole on the rear wall and optical fiber 3 closely cooperates, transparent chamber 2 can be communicated with pipe 1 endoporus of threading a needle, and optical fiber 3 (except that rear end axle 31) is suspended in the transparent chamber 2 and puncture needle tubing 1 hole in, approximately its front end reaches close bevel needle 11 places of puncture needle tubing 1, this puncture needle tubing 1 endoporus can allow the flow of liquid mistake, in addition, in transparent chamber 2 and puncture needle tubing 1 rear end, the equal coating adhesive in outer face (as: glue etc.) that the rear end axle 31 of optical fiber 3 cooperates increases the sealing that connects.
Claims (3)
1, a kind of optical fiber pin of blood of human body irradiation usefulness comprises puncture needle tubing and optical fiber, it is characterized in that: it also be provided with it concentric before cinclides and back cinclides fit snugly in transparent chamber on the rear end axle of puncture syringe rear end and optical fiber pin respectively, and optical fiber is suspended in the transparent chamber and the puncture needle tubing in.
2, by the optical fiber pin of the described blood of human body irradiation of claim 1 usefulness, it is characterized in that: above-mentioned transparent chamber is lucite or plastic flexible pipe.
3, by the optical fiber pin of the described blood of human body irradiation of claim 1 usefulness, it is characterized in that: the equal coating adhesive in the close-fitting outer face of rear end axle of above-mentioned transparent chamber and puncture needle tubing, optical fiber pin.
