Description
Technical field
The present invention relates to a kind of pressure measurement probe, especially the pressure measurement probe of optical fiber pressure tester.
Background technology
On clinical medicine, accurately measure body-internal-circulation venous pressure, for medical diagnosis on disease treatment and pathological study, there is very great meaning.
Modern medicine is thought, the major complications of liver cirrhosis is hepatites virus infections person and hepatopathy patient, and its consequence necessarily portal blood pressure is abnormal to be increased, thus causing esophageal varicosis and sudden high-risk bleeding. Esophageal veins blood pressure and portal blood pressure and hepatic vein pressure ladder value linearly related law, measuring esophageal veins blood pressure is clinically for monitoring and judge the effective means of patient's bleeding omen. Clinically by detection esophageal veins pressure, it has also become the important means of auxiliary Clinics and Practices monitoring.
At present, vein pressure measurement, it is generally required to complete by endoscope, detects subject content as internal, and clinical practice mainly has intravenous pressure measurement and two kinds of forms of vein measuring pressure from outside, the former measures blood pressure by fine needle aspiration cirso-, and the latter touches measurement esophageal variceal vein blood pressure. Puncture measurement to be prone to cause hemorrhage and cause infecting, be rarely used in clinic; Touching measurement and have multiple method, detection method observed by conventional have conduit UNICOM detection method and air bag.
Fiber-optic pressure sensor detection is a kind of novel non-invasive venous pressure measuring method, currently clinical medicine expansion application, the vein measuring cell of wherein employing photoelectric measurement principle realization detection and employing Fibre Optical Sensor are new techniques as the application of measuring probe.
In the patented technology that the present inventor has applied for, patent of invention " the venous pressure measuring probe of a kind of clinical medicine application ", ZL201220232221; Patent of invention " a kind of venous pressure measuring probe and installation method, using method ", 2012101605500, sufficient explanation has been done in the design for related vein pressure measurement instrument. But; the measuring probe being used as measurement and collection pressure signal is then the weak link of whole application system; by the restriction of its composition material structure and process conditions, the deficiencies such as the service life of measuring probe is short, certainty of measurement is low, posterior maintenance is difficult, constrain scale and manufacture process.
Summary of the invention
The technical problem to be solved in the present invention is to provide the pressure measurement probe of a kind of optical fiber pressure tester, it is intended to improve measuring probe detection accuracy in clinical practice.
The present invention is achieved through the following technical solutions.
A kind of pressure measurement probe of optical fiber pressure tester, including visiting cylinder, Membrane cover, sealing ring, diaphragm seal, transmitting medium, above-mentioned Membrane cover is the tubular structure of one end open, its opening is sleeved on above-mentioned spy cylinder, above-mentioned Membrane cover side has one section of hollow out and arranges above-mentioned diaphragm seal and be sealed against, above-mentioned sealing ring is arranged in above-mentioned spy cylinder, and above-mentioned spy cylinder, above-mentioned Membrane cover, above-mentioned sealing ring constitute confined space and fill above-mentioned transmitting medium.
Further, above-mentioned Membrane cover is wedge shaped, and the side with above-mentioned diaphragm seal tilts, and above-mentioned Membrane cover is gradually increased by its diameter of end of front end to above-mentioned diaphragm seal.
Further, above-mentioned spy cylinder is that front opening is tapered, the tubular structure of back-end sealing, and longer one end, above-mentioned spy cylinder front end is stretched into above-mentioned Membrane cover and had the side of diaphragm seal.
Further, above-mentioned spy cylinder is provided with in a circle to groove, and the above-mentioned interior spy cylinder diameter limited to groove is in order to spacing to above-mentioned sealing ring.
Further, above-mentioned spy cylinder is provided with interior to concave point, for limiting the parts of assembling in above-mentioned spy cylinder.
Beneficial effects of the present invention:
During use, measuring probe is arranged on the detection catheter proximal end of vein measuring cell, it is touch type pressure measurement apparatus with detection catheter combination, implanted by the guiding of endoscope, and it is positioned at the vein blood vessel surface measurement needing to detect, (such as, when measuring the venous pressure of esophageal varicosis patient, leading gastroscope is detected and determines by inspection vessel position, to be mounted with that the detection conduit that pressure measurement is popped one's head in imports by inspection blood vessel surface by endoscopic biopsy hole again, implement touch type detection operation, last for several seconds, until vein measuring cell display terminal report data or figure tend towards stability after namely complete measure operation. )
Disclosed detection method is, adopts measuring probe and detection conduit integral structure, and probe is directly encapsulated into catheter proximal end, and the detection face of probe is parallel with probe column axis. Time actually used, restriction due to endoscope's inherent structure, the detection face of probe has angle with by inspection blood vessel cylinder, easily produce when mutually touching to touch blind area (region that two curved surfaces do not touch), cause Ink vessel transfusing blood flow pressure can not conduct completely to the detection face of probe and by its perception, affect accuracy of detection. The present invention adopts wedge shape detection Membrane cover, namely Membrane cover side and with its axis be one angle construct one tilt detection face, can solve the problem that probe cylinder is with when being had angle by inspection blood vessel cylinder, detection membrane remains to be formed parallel touching with blood vessel cylinder, ensures the conduction of blood flow pressure non-blind area.
As pressure measurement apparatus matching used with endoscope, it it is the system and device of a kind of repeated application, owing to use procedure can be subject to the pollution of secretions and physiological tissue in the patient, must detect in every example and carry out strict cleaning and sterilizing afterwards, this operation not only process is strictly complicated, and very easily damage probe detection face, cause perception element failure. The measuring probe of present invention design is disposable simple Devices, by filling transmitting medium in advance, disinfects, and carries out sealed storage. By the operation of grafting efficiently and detection conduit compact siro spinning technology during use, fast it is combined as touch type pressure measurement apparatus; Use complete, radioactive content probe need only be extractd, exempt the cleaning and sterilizing process of probe, (detection conduit portion more than probe is owing to being in the biopsy hole of endoscope all the time in use procedure, the degree being subject to internal pollution is relatively low, the operation of corresponding cleaning and sterilizing is relatively easy, and also detection face need not be taked special maintenance measure).
