The specific embodiment
For the purpose, technical scheme and the advantage that make this utility model is clearer,, this utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation this utility model, and be not used in qualification this utility model.
Please consult Fig. 1 and Fig. 2 in the lump, the structural representation of the venous pressure measuring probe that its adaptation clinical medicine that provides for this utility model preferred embodiments is used.The venous pressure measuring probe comprises flexible inner bag 1, stiff case 2 and stress transmitting medium (indicating), and wherein, the stress transmitting medium riddles in the inner bag 1, and inner bag 1 is installed on the housing 2.In this embodiment; The stress transmitting medium is liquid normal saline (concentration is 0.9% NaCl aqueous solution); Certainly can also be other liquid medium harmless in other embodiments, as select the methyl-silicone oil (Silicone Oil) etc. of the low coefficient of viscosity and higher resistance to compression for use human non-toxic.
Please combine Fig. 3 and Fig. 4, inner bag 1 comprises support 20, fibre optic compression sensor 4, optic fibre wire 3 and tubular thin film cylinder 26.
Fibre optic compression sensor 4 is between first installation end 11 and second installation end 13; Fibre optic compression sensor 4 is fixed on the optic fibre wire 3 and with optic fibre wire 3 and electrically connects; Refer to that mainly making the optics hot melt connects, optic fibre wire 3 extends the ball top of second installation end 13 via the first optical fiber leadout hole 15.
Tubular thin film cylinder 26 is accommodated support 20; The two ends of thin film cylinder 26 and first installation end 11 and second installation end 13 are fixing; Thin film cylinder 26, first installation end 11 and second installation end 13 form an annular seal space 10; Fibre optic compression sensor 4 is housed in the annular seal space 10, and transmitting medium entrance hole 14 communicates with annular seal space 10.Preferably, thin film cylinder 26 is the polyurethane layer of thickness 0.03mm, is transparence.
It is material that housing 2 adopts titanium, aluminium alloy, and housing 2 comprises end 31, package cover 33 and connects end 31 and package cover 33 and the tubular accepting groove 32 of opening.End 31 is smooth hemisphere head.Package cover 33 can be separated with accepting groove 32 engagings, and it is a variety of that the mode of engaging has, and in this embodiment, adopts the mode of conventional inserting groove 36 engagings.The top of package cover 33 vertically stretches out and becomes to be threaded post 37, and the post 37 that is threaded offers the second optical fiber leadout hole 35 that communicates with accepting groove 32, and the cross section of accepting groove 32 is curved.
The venous pressure measuring probe encapsulates (being 20 ℃ of normal pressure and temperature environment 101325Pa) under normal conditions and gets final product when mounted, and its installation steps are following:
With fibre optic compression sensor 4 and the optic fibre wire 3 that is connected thereof; Inboard from second installation end 13 of internal bladder support 20 outwards passes; The joint portion of pick off 4 and optic fibre wire 3 is fixed on the first optical fiber leadout hole, 15 inboards (in this embodiment; Adopt hot melt material fixing as: high density polyethylene (HDPE)), the gap between hermetic fiber lead 3 and the first optical fiber leadout hole 15 makes pick off 4 place on the axis of second installation end 13 through its optic fibre wire that is connected 3 supports simultaneously;
Tubular thin film cylinder 26 covers are rolled in the internal bladder support 20 that comprises first installation end 11 and second installation end 13, and leveling tubular thin film cylinder 26 also keeps the pellicular front equalization of strain;
Two ports of tubular thin film cylinder 26 are bonding (in this embodiment with first installation end 11 and second installation end 13 of internal bladder support 20 respectively; Bonding medium adopt chemical material as: ECA); Be axial symmetric ball shape after tubular thin film cylinder 26 and internal bladder support 20 are bonding; Its first installation end, 11 places leave transmitting medium entrance hole 14, the second installation ends 13 places and draw optic fibre wire 3;
The stress transmitting medium is annotated 14 through the transmitting medium entrance hole go into inner bag; Reach full state until it; Clog transmitting medium entrance hole 14 then (in this embodiment; Adopt hot melt material as: high density polyethylene (HDPE) filling transmitting medium entrance hole 14), make it form the inner bag 1 with annular seal space 10, the cylinder zone that the annular seal space 10 of this inner bag 1 is filled the stress transmitting medium promptly can be used as test surface (in this embodiment, being the rectangle curved surface);
At this moment, this venous pressure measuring probe installs.In this embodiment; For inner bag 1 can better be stabilized between accepting groove 32; Be provided with viscose between inner bag 1 and the accepting groove 32, certainly in other embodiments, this viscose can not adopt yet; Flexibility and accepting groove 32 self rigidity through inner bag 1 self combine; While can well be firm between inner bag 1 and the accepting groove 32 by end, package cover and accepting groove 32 cooperation each other, can not influence the normal use of this venous pressure measuring probe.
This venous pressure measuring probe in use; With the flexible test surface of this measuring probe, ride over measured vein blood vessel surface by post to parallel mode, and apply applied external force perpendicular to test surface; Promptly measure external force, make the thin film of this flexibility test surface that concavo-convex deformation take place;
When venous pressure was higher than normal pressure, recessed deformation took place in this thin film;
The spatial volume of measuring probe generation deformation and the blood pressure pressure of internal blood vessel are the linear with joint efforts of three kinds of active forces of measurement external force of applying of vein pressure, blood vessel surface tension force and operation; Wherein measuring external force acquires a certain degree; When being the whole pressings of flexible test surface to blood vessel surface; The numerical value of making a concerted effort that measurement is read keeps relative stability; The numerical value of making a concerted effort of above-mentioned three kinds of active forces is outputed to data analysis device (in this embodiment, referring to a kind of digital terminal equipment based on microprocessor control special in the industry), in data analysis device; Through the algorithm routine calculating acquisition internal blood vessel force value of operation by the empirical model design, i.e. venous pressure value.
This venous pressure measuring probe adapts to clinical medicine and uses; It has the liquid medium of identical internal stress; During through the relative pressing of compliant interface after the encapsulation separately, its zone that is in contact with one another overcomes surface tension generation deformation, and deformation causes the medium internal stress to be transmitted and tend to be balanced to low by height.Because the volume of this utility model is small; Can and be deep into inside of human body by medical endoscope and survey position enforcement pressure measurement operation through its biopsy tool passage; Can be used as the critical component of non-invasive venous pressure measuring device, adapt to the inside of human body venous pressure is measured, effective no-invasive property sniffer.
The above is merely the preferred embodiment of this utility model; Not in order to restriction this utility model; Any modification of being done within all spirit and principles at this utility model, be equal to replacement and improvement etc., all should be included within the protection domain of this utility model.
