This device comprises a positioning device front terminal (4), a disposable aseptic protector (5), a positioning device back terminal (6), a positioning screw (11), a conical bore (12) and graduation marks (3). This device is small in size and handy and solves the problem being an international trouble for 20-30 years that an imager experiences image shaking with image pressure not easy to control and thus is unable to be popularized and used clinically.
Description
Technical field
The present invention relates to a kind of device stablizing image and control probe to object of observation contact pressure, especially for hands
Hold the one of the circulatory monitoring imager that declines (hereinafter referred to as imager) to stablize image and contact pressure with controlling probe to the object of observation
The device of power, belongs to hand-held microcirculation monitoring device technical field.
Background technology
Microcirculation monitoring technology has weight for early diagnosis treatment and the prognosis of distributivity shock (its representative is sepsis)
Wanting meaning, monitoring microcirculatory method has hand-held cross-polarization spectrum (OPS) imaging technique and more advanced by-pass flow dark ground
(SDF) imaging technique, it is achieved that noinvasive, visual microcirculation are monitored.OPS technical work principle is that light source sends (550 ± 70)
The green glow of nm wavelength, through two mutually perpendicular polarizeies, polarized light is filtered across, and depolarization light enters electricity by polarizer
Lotus coupled apparatus (CCD) and camera imaging, SDF technology is the deriving technology of OPS technology, uses LED to make
For light source, sending (540 ± 50) nm (green) light, CCD sight glass uses the position that blood capillary is enriched by dark field image technology
Carry out dynamic image collection and record.
United States Patent (USP) US8,452,384 B2 discloses the system and method for a kind of by-pass flow dark ground image.(systems
And methods for sidesstream dark field imaging), this hand-held microcirculation by-pass flow dark ground shadow
As imager, it uses SDF technology, can observe the lectin from hemolymph at the positions such as humans and animals privileged sites such as Sublingual, kidney, intracranial
Change, directly observed by screen, it is provided that function capillary vessel number, external caliber and the flow velocity of humans and animals, pass through software
Obtaining related data, this equipment has convenience, can directly experiment bedside at laboratory carry out, and operation is simple, but
It is, the when of using this hand-held microcirculation by-pass flow dark ground video imaging instrument to observe in Sublingual, to be the most all operation
Personnel's hand-held instrument is directly observed, owing to the physiological of people is shaken so that imager is difficult to obtain more stable observation figure
Picture, requires higher to the operating experience of operator；In addition the camera lens of imager directly bears against and observes on skin or mucosa
Time, owing to the pressure of skin is not easy appropriately to hold by hand-held camera lens, so when pressure is excessive when, blood can be affected
Flow velocity, causes the data obtained inaccurate, and the least camera lens making again imager of pressure departs from mucomembranous surface and causes image pole not
Clearly cannot be carried out analyzing.
In order to solve the problems referred to above, article < < improvement of effluent dark-field imaging and the figure that University of Amsterdam delivers
Stable as gathering > > (Improvement of Sidestream Dark Field Imaging with an Image
Acquisition Stabilizer) [1], article discloses employing probe distal end and places a rustless steel sterilizing ring, sterilization
Ring has 20 holes outwards to bleed generation negative pressure, and negative pressure can obtain by using bed side vacuum source and pressure regulator, and negative pressure is led to
Cross 20 hole paths absorption hypoglossis mucous membranes and press close to probe distal end to prevent flating and to keep constant contact pressure, this way
Need vacuum pump, cumbersome, so make what portable equipment became can not use flexibly, vac sorb follows for Sublingual is micro-simultaneously
The naturalness of ring also can be influential, and image and the pressure stability problem of hand-held microcirculation monitoring device never obtain
Well solve, have impact on the clinical practice of this instrument.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of and stablizes image and control probe to object of observation contact pressure
Device, the device of this stable image and control probe contacts pressure includes positioner front end and positioner rear end, this
Individual positioner front end can be fitted in the surface of the object of observation, thus solves above-mentioned two problems.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of image and control probe stablized is to the object of observation
The device of contact pressure, including positioner front end and positioner rear end, it is characterised in that: described positioner front end with
Positioner rear end is arranged in the region of elongate probe radius 100 millimeters of imager, connects with imager main frame, institute simultaneously
The positioner front end stated is connected with positioner rear end, and positioner front end can be fitted in the surface of the object of observation, location
Band dynamic positioning system front end, device rear end can be reciprocating along the direction of imager main frame elongate probe axial direction signal,
Move back and forth regulation through this, have adjusted the work of positioner front end and elongate probe disposable taper protection device leading section
It is fixed on imager main frame after making distance.
Further, described stable image and control are popped one's head in the device of object of observation contact pressure, described location
Device front end is the most porose with positioner back-end central, can allow in imager elongate probe or in the disposable taper of elongate probe
Protection device is passed through from hole.
Further, described stable image and control are popped one's head in the device of object of observation contact pressure, thin at imager
Long probe is upper or has axial distance scale to indicate in elongate probe disposable taper protection device, indicates for positioner front end
Orientation distance.
Further, described a kind of device stablizing image and control probe to object of observation contact pressure, its location
Device front end once property sterile protecting apparatus covers, to prevent cross infection.
Further, described disposable sterilized protection device is middle porose so that imager elongate probe and elongated spy
Property taper protection device can pass from hole for the first time.
Further, described stable image and control are popped one's head in the device of object of observation contact pressure, by positioner
Behind rear end and imager main frame regulation suitably distance, by set screw or other modes positioner front end and positioner
Rear end is fixed with imager main frame relative distance.
Further, described stable image and control are popped one's head in the device of object of observation contact pressure, by positioner
Rear end is connected by electric pushrod connector with electric pushrod, and electric pushrod parent and the fixing connection of imager main frame, motor is just
Invert 2 control knobs and control motor positive and inverse so that electric pushrod moves back and forth, and positioner front end is adjusted to suitably
Position,
Having micromachine and helical structure inside electric pushrod, the control circuit of motor positive and inverse, these technology belong to known skill
Art, repeats no more.
Beneficial effects of the present invention
This stable image is small and exquisite with the device of control probe to object of observation contact pressure and facilitates, and solves puzzlement both at home and abroad
20-30 over many years imager flating and image pressure be not easily controlled, thus problem (this that can not commonly use in clinic
It is that the type instrument can not be comprehensively in one of the major reason of Clinical practice).
