The ultrasonic testing system of a wireless touch key sets accepted way of doing sthTechnical field
The present invention relates to medical instruments field, particularly relate to B ultrasonic checkout and diagnosis equipment.
Background technology
B ultrasonic checkout and diagnosis instrument produces incident ultrasound wave (transmitted wave) by probe and receives reflection supersonic wave (echo), is used for detecting the diagnostic device organizing organ site, characteristic.B ultrasonic checkout and diagnosis instrument mainly comprises main frame, display, probe and supervisory keyboard, wherein main frame connects probe by cable, cable connects except operation and carries except inconvenience, the length of cable also seriously limits the scope of application of probe, cable in use also easily damages in addition, affects the service life of B ultrasonic checkout and diagnosis instrument.Existing B ultrasonic monitoring device is equipped with multiple different probe usually to meet different detection needs, when needs switch probe, all will arrange on keyboard each time, complex operation, have a strong impact on the detection efficiency of doctor; The cable of multiple probe is easily intertwined simultaneously, uses inconvenience, also can damage cable and cause any property loss time serious.
Summary of the invention
The applicant, for the above-mentioned shortcoming of existing B ultrasonic checkout and diagnosis instrument, provides that a kind of structure is simple, easy to operate, detection range is wide, the ultrasonic testing system of a wireless touch key sets accepted way of doing sth for long service life.
The technical solution adopted in the present invention is as follows:
A kind of ultrasonic testing system of a wireless touch key sets accepted way of doing sth, the display, the manipulation keyboard that comprise main frame, probe and be electrically connected with main frame, probe comprises supersonic generator and ultrasonic receiver, and supersonic generator and ultrasonic receiver are connected with the first outfan of control unit and the second outfan respectively; The outfan connection signal processing unit of ultrasonic receiver, signal is delivered to main frame by plug by signal processing unit; Probe internally provided have power supply, and it also comprises wireless transmission unit, and plug connects radio receiving unit, and signal is sent to plug by wireless transmission unit and radio receiving unit by signal processing unit; Probe is provided with touch pad, touch pad is arranged multiple touch key-press; Touch pad is connected with control unit and plug respectively by switch unit, switch unit comprises decoder, controls latch and switch arrays, the signal output part of decoder is connected with control latch, switch arrays are by controlling latch lockout switching signal, and the outfan of switch arrays exports switching signal to control unit respectively.
Further technical scheme is:
Main frame is connecting valve evaluator also, and on switch identifier, device has switch indication light.
Beneficial effect of the present invention is as follows:
1, the present invention adopts wireless transmission method, improves the convenience of operation, expands the detection range of probe, save due to cable fragile and produce maintenance cost, extend service life of the present invention;
2, owing to arranging touch pad on probe, probe is switched, decrease cable and probe number, avoid stirring between cable, reduce cost, and the touch key-press of touch plate type also has dustproof and waterproof function, substantially prolongs the service life of probe.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1, Fig. 2 and Fig. 3, the display 16, the manipulation keyboard 17 that the present invention includes main frame 15, probe 6 and be electrically connected with main frame 15, probe 6 comprises supersonic generator 8 and ultrasonic receiver 9, and supersonic generator 8 and ultrasonic receiver 9 are connected with the first outfan of control unit 7 and the second outfan respectively; The outfan connection signal processing unit 10 of ultrasonic receiver 9, signal is delivered to main frame 15 by plug 12 by signal processing unit 10; Probe 6 is built-in with power supply 19, and it also comprises wireless transmission unit 11, and plug 12 connects radio receiving unit 18, and signal is sent to plug 12 by wireless transmission unit 11 and radio receiving unit 18 by signal processing unit 10; Probe 6 is provided with multiple touch pad 1, touch pad 1 is arranged multiple touch key-press 1-1; Touch pad 1 is connected with control unit 7 and plug 12 respectively by switch unit 2, switch unit 2 comprises decoder 3, controls latch 4 and switch arrays 5, the signal output part of decoder 3 is connected with control latch 4, switch arrays 5 are by controlling latch 4 locking switch signal, and the outfan of switch arrays 5 exports switching signal to control unit 7 respectively; Connecting valve evaluator 13 gone back by main frame 15, and on switch identifier 13, device has switch indication light 14, and whether switch indication light 14 starts probe 6 for pointing out operator.
When the present invention works, owing to being provided with touch pad 1 on probe 6, when starting one of them touch key-press 1-1 on touch pad 1, signal is exported to control unit 7 by switch unit 2, the ultrasound wave that control unit 7 starts different frequency detects human tissue organ, the signal that probe 6 detects is successively by signal processing unit 10, wireless transmission unit 11, radio receiving unit 18 and plug 12 pass to main frame 15, main frame 15 converts the signal into image and shows on display 16, wherein when probe 6 is in running order, switch identifier 13 start switch indicator 14 on main frame 15, probe 6 has been started to point out operator.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
