Abstract
A pressure detecting accessories for ultrasonic probe aims mainly to obtain pressure wave information when performing ultrasonic detecting. When detecting, the filling liquid in an obturation cavity is used as a sound-penetrating widow for ultrasonic detecting and as the conducting medium for pressure detecting, the ultrasonic probe arranged at the top of the sleeve can directly perform ultrasonic detecting. A pressure sensor is arranged at the outer wall of the sleeve to detect the pressure transferred by the conducting medium and to convert the detected signal into output electronic signal. When in use, an elastic film contacts the detected surface, because the deformation of the contact face of the elastic film depends directly on the force to the elastic film, while the deformation is caused by the change of sphygmus wave of human body, and the liquid in the obturation cavity can transfer the pressure to the pressure sensor, so the pressure detecting can be performed.
Description
Technical field
The present invention relates to the biomedical signals measuring field, particularly the pressure at pulse position, vasomotion status detection.
Background technology
Employed ultrasonic frequency is generally 0.5MHz~15MHz in the medical diagnosis, and the ultrasonic wafer that is mostly to be made by the material of piezoquartz one class produces.Ultrasonic probe contacts with human body skin, surveys the internal of human body from human external.When carrying out the seeking and visiting of human body superficial place, image fault for blind area, near field, the reverberation effect avoiding popping one's head in or after organizing pressurized, generally probe with survey usefulness between the position and be full of the plastics water pocket of the water that degass or other liquid as the entrant sound medium, foundation sound window is to improve its display resolution.
Site pressure methods commonly used such as detection pulse are to adopt the pressure-detecting device that comprises piezoelectric element or deformation detectors equal pressure pick off, the part of pressure-detecting device contact skin surface during use, the stress that is added on pressure transducer changes with the displacement of skin surface, and pressure transducer output is with the signal of telecommunication of this STRESS VARIATION.
When the motion of studying pulse, blood vessel etc. and state, need to carry out simultaneously the detection of ultrasound wave and pressure sometimes, to carry out analysis-by-synthesis and diagnosis.But, carry out because the pulse ultrasound examination detects to separate with pulse pressure all the time, can not obtain the information of the ultrasound wave and the pulse at the same position of synchronization, this will bring very big drawback to later subsequent analysis and diagnosis clinically.
Summary of the invention
This utility model provides a kind of additonal pressure checkout gear that is used for ultrasound probe, and main purpose is the pressure wave information that obtains when carrying out ultrasound examination.When detecting, utilize filling liquid in the closed chamber as the sound transmitting window of ultrasound detection and the transmitting medium of pressure detecting, carry out the measurement of ultrasound wave and pressure wave simultaneously.
The technical scheme that its technical problem that solves this utility model adopts is: attachment device is a sleeve, telescopic upper end can be inserted ultrasound probe and be airtight, telescopic lower end is sealed by an elastica, closed chamber of telescopic intermediate formation, the intracavity full of liquid is simultaneously as sound transmitting window and pressure transmitting medium.One side of sleeve wall has tracting pressuring hole, as the passage of pressure transmission.
The ultrasound probe that is installed in the sleeve upper end can directly carry out ultrasound examination.Pressure transducer is installed on telescopic outer wall, is used to detect transmitting medium and transmits next pressure and the conversion of signals that detects is become signal of telecommunication output.Elastica contacts with measured surface during use, and elastica according to the pulse wave of human body corresponding deformation takes place, and causes the variation of cavity pressure, by airtight intracavity liquid pressure is passed to pressure transducer, realizes pressure detecting.
The beneficial effects of the utility model are: carry out ultrasound examination the time, utilize filling liquid in the closed chamber as the sound transmitting window of ultrasound examination and the transmitting medium of pressure detecting, the pressure wave signal of finishing tested position synchronously detects, for follow-up multiple combined signal analyzing and processing and application clinically provide a great convenience.This device can detect position, the especially arterial pulse that the various generations of body surface are beaten.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
1. ultrasound probes in the Figure of description, 2. sleeve, 3. elastica, 4. transmitting medium, 5. tracting pressuring hole, 6. pressure transducer, 7. sealing ring.
The specific embodiment
In the embodiment shown in the Figure of description, sleeve (2) is made by metal material, and ultrasound probe (1) inserts its upper end and seals with sealing ring (7).Ultrasound probe (1) by transmitting medium (4) emission and the reception ultrasound wave that the entrant sound effect is arranged, shows the two-dimensional ct image (ultrasonograph figure) of tested tissue.Built-in transmitting medium (4) is a filling liquid, and tracting pressuring hole (5) is opened in a side of sleeve (2).Elastica (3) is fixed in an end of sleeve (2), and with the sealing of sleeve lower end, the stressed generation deformation of elastica (3) changes the closed chamber internal pressure, passes to pressure transducer (6) by airtight transmitting medium (4) via tracting pressuring hole (5).Pressure transducer (6) detected pressures signal is converted into signal of telecommunication output.
Claims (1)
- A kind of pressure detecting attachment device that is used for ultrasound probe, comprise sleeve, pressure transducer, liquid medium and elastica, it is characterized in that: the main body of attachment device is a sleeve, telescopic upper end can be inserted ultrasound probe and be airtight, telescopic lower end is sealed by an elastica, closed chamber of telescopic intermediate formation, but intracavity is full of the liquid medium that can see through ultrasound wave and conducting pressure, one side of sleeve wall has tracting pressuring hole, links to each other with the pressure transducer that is installed on telescopic outer wall.
