Abstract

The utility model relates to an improvement and an innovation of a weak laser inner irradiation device for blood vessels of the human body. The utility model which can be taken as an accessory is arranged on a laser blood vessel inner irradiation therapeutic apparatus. The device is composed of a laser source, an optical fiber coupler, an optical fiber and a sublingual inserting outer sleeve. The blood irradiation with the wound is changed into the blood irradiation without the wound by using the device. The disposable sublingual inserting outer sleeve can prevent the cross infection.

Description

Weak laser Sublingual blood vessel irradiation unit

Weak laser shines vessel inner blood by optical fibers, is a kind of to the effective modern non-drug medical method of multiple difficult and complicated illness treatment.This utility model is the improvement and the innovation of laser blood illuminator device, can be used as adnexa and is provided on the laser intravascular radiation therapeutic apparatus.

Existing Intravascular Laser Irradiation on Blood blood method is as Chinese patent application number a kind of helium of 93115055 (bulletins)---Ne laser intravascular irradiation therapeutic equipment, application number 94208099 (mandate) laser ultraviolet blood irradiation therapeutic instrument, and employed method in the intravascular laser irradiation document of reporting both at home and abroad, all be after adopting ferrule pin puncture vessel, again laser to be imported blood and shine.This be a kind of have to dig hinder Therapeutic Method.Repeatedly puncturing for patient's blood vessel is a kind of damage and misery, also makes troubles to medical worker's operation.

The design's purpose is a kind of device of design, change existing laser blood illuminator method, promptly create a kind of effective and feasible laser extravascular irradiation hemotherapy, becoming has trauma care to treat into no wound, and this just must have a laser not have the window that wound ground leads to blood of human body, has selected the sublingual vein blood vessel through putting into practice the design, because the sublingual vein blood vessel is more, and be exposed under the very thin mucous layer, laser is good in the light transmission that this enters blood, and loss is little.The capillary vessel in Sublingual is also very abundant in addition, directive mucosa and venous blood tube wall also can not shone the Sublingual blood capillary once more by the scattered beam of blood absorption, make blood absorb luminous energy once more, improve blood illuminator efficient.

To achieve these goals, the design is by LASER Light Source [1], fiber coupler [2], and optical fiber [3], the Sublingual is inserted trocar sheath [4] and is formed.LASER Light Source in the design's the structure [1] can be gas laser, semiconductor laser, solid state laser etc.Fiber coupler [2] is made up of fiber coupler overcoat [5], spring leaf [6], fiber orientation dish [7], bolt [8], lens [9], lens clamp [10].Fiber orientation dish [7] can slide up and down at the end face of the elastic force of spring leaf [6] compressing lower edge lens clamp [10], its slip plane just in time overlaps with the focal plane of lens [9], laser beam can be similar to regards a collimated light beam as, scioptics focus on the back and form very little girdling the waist on the focal planes, being with the optical fiber of insertion when fiber orientation dish [7] moves up and down, make laser beam just in time converge at the center of fiber end face, laser coupled is entered optical fiber, this moment, the other end of optical fiber was exported the laser power maximum, optical coupling efficiency is the highest, then set bolt [8] is screwed, make fiber orientation dish [7] fixing, after this insert again after optical fiber coupling plug [11] is in use transferred to and laser can both be coupled into well optical fiber [3], do not need often to move, regulate fiber orientation dish [7].The other end of optical fiber [3] is with the Sublingual of being made by light transmissive material that one one end seals an end opening and inserts trocar sheath [4], its opening is equipped with the foraminous elastomeric material medicated cap in a center [12], optical fiber [3] is by inserting in the hole, hole diameter is more smaller than optical fiber [3] diameter, can utilize its resilient clamp to live optical fiber [3], and allow optical fiber [3] to move forward and backward, reach the Sublingual and insert top within the trocar sheath [4].Optical fiber [3] utilizes the angle of divergence of optical fiber outlet when moving forward and backward, and regulates irradiated area and power density that trocar sheath [4] top outlet is inserted in the Sublingual.

Compare with existing laser intravascular radiation therapeutic apparatus according to this new pattern laser blood illuminator device that above-mentioned purpose of design is designed, its characteristics be to make original have to dig hinder therapy and become no wound and treat, having reduced patient's blood vessel injury and misery and optical fiber pin repeatedly sterilizes and uses the cross infection that might bring, the pollution that has the wound operation also may bring other, trocar sheath [4] is inserted in the transparent Sublingual of using among the design, cheap can disposablely the use, easy to operate.Existing in addition Intravascular Laser Irradiation on Blood instrument, optical coupling is for the second time arranged between Transmission Fibers and the optical fiber pin, current coupling loss is about 20-30%, reduced current coupling among the design, light transmissioning efficiency is improved, benefit has been tasted the loss of laser on mucosa and blood vessel wall, if the output of corresponding again enhancing laser instrument will reach more effective therapeutic effect.Non-invasive blood irradiation will make thisly up-to-date has the laser blood of good curative effect to apply according to therapy is easier to multiple difficult and complicated illness.

The Figure of description explanation:

Figure one shows the design's connection diagram, and [1] is LASER Light Source, and [2] are fiber coupler, and [3] are Transmission Fibers, and [4] insert trocar sheath for the Sublingual, and [12] are the elastomeric material medicated cap.

Figure two show the design fiber coupler [2] and with the connection layout of optical fiber coupling plug [11].[3] be Transmission Fibers, [5] are the fiber coupler overcoat, and [6] are spring leaf, and [7] are the fiber orientation dish, and [8] are bolt, and [9] are lens, and [10] are lens clamp, and [11] are optical fiber coupling plug.This fiber coupler has half adjustable character.Adjusting fiber orientation dish [7] can make laser converge through lens [9] and enter in the optical fiber [3].

One of better example of the design is:

As shown in the figure, what LASER Light Source [1] adopted is the He-Ne laser instrument, output is below the 5mW, the focal length of lens [9] is 20mm, with a tight waist just in time the dropping on the bottom surface of fiber orientation dish [7] that laser beam converges, fiber orientation dish [7] is being with optical fiber [3] to move up and down, and reaches to make laser beam be coupled into the most effective of optical fiber.Optical fiber [3] is the big core diameter list of Φ 0.6mm core silica fibre, and external diameter is Φ 1.3mm, and fiber lengths is 1200mm.It is long 70mm that trocar sheath [4] is inserted in the Sublingual, external diameter Φ 5mm, the glass tubing of internal diameter Φ 3mm.Can disposable use prevent cross infection.

This weak laser Sublingual irradiation unit is very easy to use, under the non-invasive blood radiation situation, also can obtain multiple treatment of diseases effect, reduce misery to the patient, easy to operate and safe, be easier to promote, can be used as adnexa and be provided on the low-power intravascular irradiation therapeutic equipment, a kind of treatment that increases doctor and patient is selected.
