The axial ecto-entad of described fibre-optical probe is followed successively by the fibre-optical probe seat, optical fiber protective tube and the optical fiber that connect one.
Fibre-optical probe seat outside dimension coordinates with the centre bore of conical seat, and its top and conical seat two horizontal elongated hole para-positions place are designed with groove.
The end face of optical fiber and human contact is hemisphere face.
Optical fiber protective tube is made up of metal material, is sleeved on outside optical fiber, and the hemisphere face end face of optical fiber is exposed to outside optical fiber protective tube.
Another object of this utility model is to provide a kind of light source probe, and the structure of the replaceable probe described in utilization, is equiped with LD light source module and collimating lens from top to bottom in mount pad, and the distance of collimating lens and LD light source module lower end is 1-4mm.
A this utility model again object is to provide a kind of detector probe, and the structure of the replaceable probe described in utilization, is equipped with precise light electric diode and optical filter from top to bottom in mount pad, and upper end and the optical filter of fibre-optical probe are close to installation.
A this utility model also object is to provide a kind of Near-infrared Brain hematoma detector, includes detector body, it is characterized in that, the base of detector body front end is provided with the aforesaid light source probe and detector probe that stretch out downwards.
Described Near-infrared Brain hematoma detector, the spacing of two fiber probe tip of light source probe and detector probe is 3-5cm.
Adopt above design, this utility model sonde configuration is simple, coordinates the replaceable sonde configuration formed to design by conical seat with fibre-optical probe, achieve the replacing of fibre-optical probe consumptive material, and light source probe is identical with the fibre-optical probe in detector probe, without the need to distinguishing during replacing, can exchange.In addition, the probe size quality as consumptive material is small, conveniently carries in a large number as low price consumptive material.

Detailed description of the invention
The inspection of near-infrared hand-held cephalophyma hinder instrument be mainly used in institute before, war is on-the-spot etc. without using in CT situation, traumatic cerebral hematoma can be detected fast in early days, comprise in frontal lobe, temporal lobe, top and occipital lobe cranium brain position dura mater, Subdural space, arachnoidea and Cerebral cortex hematoma, the cephalophyma wounded are given treatment to timely.
Its know-why: the near infrared light of wavelength 600-900nm has good penetrance to skin, skull, based on intracranial hematoma and non-Hemorrhagic location to near-infrared absorption difference of coefficients (usually reaching more than 10 times), by comparing wounded's brain antimere to the absorption characteristic of near infrared light, judge intracranial hematoma risk.
Wherein, Δ OD is both sides optical density difference, I
nfor normal side optical density, I
hfor hematoma sidelight density.
Conventional Near-infrared Brain hematoma detector includes detector body 1, the base of detector body 1 front end is provided with the light source probe 18 and detector probe 19 (shown in composition graphs 1) that stretch out downwards, light source probe 18 is for sending near infrared light, and detector probe 19 returns near infrared light for receiving intracranial and is converted to the signal of telecommunication; The spacing of two fiber probe tip is 3-5cm.Light source probe 18 and detector probe 19 have similar sonde configuration, see Fig. 2 A, include mount pad 2, conical seat 4 and fibre-optical probe 5.Wherein: for light source device probe 18, install LD light source module 6 and collimating lens 8 (see Fig. 3 A) inside mount pad 2, for detector probe 19 (see Fig. 3 B), in dress seat, be equipped with precise light electric diode 7 and optical filter 9.
Shown in composition graphs 2A, Fig. 2 B, Fig. 2 C and Fig. 2 D, show the structure of the replaceable probe of this utility model, mainly comprise mount pad 2, conical seat 4 and fibre-optical probe 5.Wherein: conical seat 4 is arranged in the bottom of mount pad 2 by mode that is bonding or that be threaded, Fig. 2 B shows conical seat 4 inside and is longitudinally provided with through hole, as the installing hole 45 of the fibre-optical probe 5 of fibre-optical probe 5, installation direction is from bottom to top (Fig. 2 C shows installation process).Conical seat 4 has the centre bore 41 of two laterally inwardly convergents at cylinder partial position on the lower side, from the inside to the outside steel ball 43, spring 44 and jackscrew 42 3 parts are installed respectively in centre bore 41, the minimum-value aperture design of centre bore 41 is less than the diameter of steel ball 43, can the outstanding part of elasticity in centre bore 41 with steel ball 43 after jackscrew 42 pretension.Fibre-optical probe 5 interts in installing hole 45.
Continue shown in composition graphs 2D, in this utility model, fibre-optical probe 5 is made up of three parts, axial ecto-entad be followed successively by fibre-optical probe seat 51, optical fiber protective tube 52 and optical fiber 53, three part be bonded as one or one-shot forming, can overallly be convenient to change as consumptive material.Optical fiber protective tube 52 is made for metal or other material, effectively can protect optical fiber 53, and prevents light from directly propagating between two probes, causes measuring unsuccessfully; Optical fiber 53 and human body contact portion's (lowermost end) are designed to hemisphere face to reduce and discomfort during head part's contact skin; Fibre-optical probe seat 51 outside dimension coordinates with the centre bore 41 of conical seat 4, and its top and conical seat 4 two horizontal elongated hole para-positions place are designed with groove 54 for holding the ledge of steel column 43.Fibre-optical probe 5 constructional simplicity of this design can be reliable, and manufacturing cost and technology difficulty are very low, ensure that it becomes droppable low value consumptive material.
Fibre-optical probe 5 and conical seat with the use of, when fibre-optical probe 5 inserts, the groove 54 of its upper design can coordinate with steel ball 43 that can be outstanding with centre bore 41 Elastic of conical seat 4, make fibre-optical probe 5 position be fixed in conical seat 4 and can not drop out, and do not affect the light conduction function of fibre-optical probe self.When after the complete wounded of detection, conveniently can to exert a force downwards drawn optical fiber probe 5 with hands, only need the fibre-optical probe 5 that more renews and light source probe 18 need not be connected or detector probe 19 is together changed.This utility model achieves the replacing of Near-infrared Brain hematoma detector consumptive material by replaceable sonde configuration, greatly saves consumables cost.
