Abstract
The invention relates to a wound radioactivity measuring instrument. The wound radioactivity measuring instrument adopts a small-area detecting probe and simultaneously controls the distance between a detecting sensitive area and a detected surface to realize radioactivity measurement for small-area body surface or wound infection.
Description
Technical field
The present invention is a kind of wound activity meter, is the radiating matter device that a kind of wounded's of measurement body surface, wound are infected with.
Background technology
The wound radioactivity survey is that surface contamination is measured in essence, and existing surface contamination measurement mechanism, detection area is bigger, and measurement result is that the mean value in the search coverage (generally is by 100cm
2Area is average), radiocontamination for small size, even the radiomaterial of being infected with is more, also probably because average in large tracts of land, cause measurement result significantly to reduce, therefore the radiocontamination degree that can not truly reflect tested position, can not satisfy the radioactivity survey requirement of body surface and wound spot contamination.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of small size to survey probe, control simultaneously survey sensitive area with by the distance of side, realize the radioactivity survey that small size body surface or wound are infected with.
The present invention mainly includes probe, main frame and stube cable; Main frame links to each other with probe by stube cable.
Probe is made up of detector and metering circuit, and the sensitive volume area of detector is no more than 10cm
2, detector will receive α and the β particle energy is converted to electric signal, and metering circuit exports main frame to after to signal screening, amplification, shaping.There is the removable aluminized plastic film protection of one deck detector outside, and in the leading edge of probe cover, is provided with the wedge shape pin that sensitive face and tested surface distance are surveyed in control, prevents that detecting area is contaminated.
Main frame is made up of power supply, measurement amplifying circuit, single-chip microcomputer and peripheral circuit, control panel, display screen and shell.Metering circuit is accepted the electric signal of probe output, after amplifying shaping, is presented on the display screen with the form of numeral and mimic diagram.Control panel is provided with power supply and alarm sound gauge tap, function knob, can set duty, type of alarm, sample-out count and the conversion of wound measurement function of main frame.The power unit of main frame is the probe power supply simultaneously.
The beneficial effect that the present invention compared with prior art has is that the region area of surveying is fit to the wound contamination measurement requirement, is difficult for contaminatedly, and measurement result display mode image has reduced the error in the wound radioactivity survey.
Description of drawings
Fig. 1 is a composition synoptic diagram of the present invention, comprising main frame 1, stube cable 2, probe 3 and data communication cable 4.
Fig. 2 is the structural representation of main frame 1.
Fig. 3 is the structural representation (side sectional view) of probe 3.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, wound activity meter main frame 1 is connected with probe 3 by stube cable 2.Probe is sensed the ray particle signal, transfers to host SCM through the amplifying circuit amplification and after comparer examination shaping, is stored in the eeprom chip by processing of single-chip microcomputer counting and record.After measurement is finished, the data of storing connect the computing machine USB interface by data cable 4, start this host communication program and will measure the data transmission of storing to computing machine, preserve with the txt file form.
As shown in Figure 2, the structure of main frame 1 is formed the sheath that mainly contains upper casing, lower casing, display screen LCD, function button, function dial, cable socket, battery compartment and TPE material.
As shown in Figure 3, the main composition of probe 3 has inner PCB circuit board, measuring sonde, outside master collet, front end end cover, screened film, rear end cap and cable socket.
