Abstract
The utility model discloses an ultrasonic coupling device, comprising an ultrasonic rubber body cushion, wherein the ultrasonic rubber body cushion comprises an elastic latex film and a rubber body wrapped by the elastic latex film. When the ultrasonic coupling device is used, the ultrasonic rubber body cushion can utilize a self-sticking paster to guarantee that the coupling device is well contacted with an object to be detected or treated in an ultrasonic application process. The rubber body cushion needs to be accorded with the shape, such as a cone, a cone frustum, a cylinder or a cuboid, of a matched ultrasonic energy converter; when the ultrasonic coupling device is used, one layer of ultrasonic coupling agent is uniformly coated on the surface of the ultrasonic energy converter and an rubber body coupling cushion is placed above the ultrasonic energy converter; and the rubber body cushion is tightly fixed on the energy converter by a fixing piece. The other side surface of the rubber body coupling cushion needs to be coated with ultrasonic coupling agent to be contacted to the object to be detected or treated. Compared with the prior art, the ultrasonic coupling device is convenient to use and the use range of ultrasonic equipment is expanded, so that the ultrasonic coupling device is particularly suitable for wild or first-aid environments.
Description
Technical field
This utility model relates to a kind of medical ultrasound coupling device, is applied to the coupling device of the transducer of Ultrasonic NDT, medical imaging or treatment.
Background technology
Utilize ultrasound wave propagation characteristic (like reflection, scattering, refraction or Doppler effect) in medium, the health status of architectural feature that can detection material (as whether having bonding strength, corrosion condition, liquid stream between intrinsic crack, structure) or organism (like the tumor in physiological make-up, the internal organs or cancer, VPV).And when sound intensity is big, utilize heat effect or mechanical effect (like acoustic cavitation, acoustic radiation force, acoustic streaming) the application (like external stone crushing, hemostasis, tumor resection, drug release or gene transfer etc.) in clinical treatment of ultrasound wave in organism more and more widely.Because ultrasound wave is a kind of mechanical wave, aerial decay is bigger, therefore need could acoustic energy be transmitted to a distant place from transducer face by coupling medium.In applications of ultrasound, this coupling medium is chosen as degassed water, ultrasonic coupling agent or colloid usually, and coupling device is chosen as tank, water pocket or water band, to reach at utmost ultrasonic energy is passed in the object body of to be detected or treatment.Though it is very simple and ripe, consuming time longer to prepare water degassing technology with vacuum technique, can not uses for a long time, and seek sources of water, prepare and store degassed water in the open air or in the ambulatory environment and all compare difficult.The ultrasonic coupling device volume that degassed water is housed is all bigger, has both needed cleaning-sterilizing to handle to avoid cross infection between the patient, uses also inconvenient.Comparatively speaking, though ultrasonic coupling agent or colloid are easy to use, when transducer dimensions or focal length were big, it was difficult evenly to smear ultrasonic coupling agent or colloid, in extrusion process, also can introduce extra bubble unavoidably.When detecting or treat end, also need remove this material, operation is trouble.Therefore no matter adopt which kind of coupling medium, ultrasonic coupling device all can not be realized quick replacing, has influenced the scope of application of ultrasonic device, especially in the open air or ambulatory environment.
Summary of the invention
The purpose of this utility model pin just is the defective to above-mentioned prior art, a kind of fast changeable is provided, is easy to preserve and the ultrasonic coupling device of disinfectant.
Its technical solution is following: this ultrasonic coupling device comprises ultrasonic colloid pad, and above-mentioned ultrasonic colloid pad comprises elastic emulsion film and the colloid that is wrapped up by above-mentioned elastic emulsion film.
Above-mentioned elastic emulsion film select for use have good sound transmission property in the prior art, the elastic emulsion film of wear-resisting withstand voltage and bio-compatible, above-mentioned colloid is selected the colloid that has good sound transmission property and less acoustic attenuation in the prior art for use.Through vacuum sealing technique,, guarantee that colloid does not dewater to keep good working order in long-time the use with the seamless unoccupied place of latex film parcel colloid.
This utility model in use, the available self-adhering type paster of ultrasonic colloid pad guarantees good contact the between in applications of ultrasound coupling device and to be detected or treatment object.The colloid pad must meet the shape of the ultrasonic transducer that is mated; Like cone, the frustum of a cone, cylinder or cuboid; Evenly smear one deck ultrasonic coupling agent on the ultrasonic transducer surface during use; Again that colloid coupling pad is placed on it, with connecting fixture the colloid pad closely is fixed on the transducer.Ultrasonic coupling agent also need be smeared in the opposite side surface of colloid coupling pad, contacts with object to be detected or treatment.Connect fixture and can adopt mechanical means such as screw thread, bayonet socket, screw, to guarantee tight contact the between ultrasonic transducer and coupling device in use.Therefore this utility model compared with prior art, and is easy to use, expanded the scope of application of ultrasonic device, especially adapts to the environment of field or first aid.

The specific embodiment
Embodiment 1: as shown in Figure 1; A kind of ultrasonic coupling device is used for focused transducer 6; Transducer face is smeared one deck ultrasonic coupling agent 7; Ultrasonic colloid pad is made up of the colloid 8 of inside and the latex thin film 3 of appearance, and concentration ultrasonic acoustic beam 4 can be transmitted to well in colloid and be positioned at the along 1 that ultrasonic coupling agent 2 is smeared on ultrasonic colloid pad surface, and self-adhering type paster 9 can guarantee that object does not depart from ultrasonic burnt territory in detection and therapeutic process.Ultrasonic colloid pad is fixed on the ultrasonic transducer 6 through connector 5.
Embodiment 2: as shown in Figure 2; A kind of ultrasonic coupling device is used for focused transducer 6; But its focus 1 is positioned at outside the ultrasonic colloid pad; Concentration ultrasonic acoustic beam 4 can be propagated in colloid well, and through the ultrasonic coupling agent 2 that smear on ultrasonic colloid pad surface, propagates and converge to be detected or the treatment interior of articles.
Embodiment 3: as shown in Figure 3; A kind of ultrasonic coupling device is used for plane ultrasonic transducer 18; Transducer emitting surface 17 is smeared one deck ultrasonic coupling agent 16; Ultrasonic colloid pad is made up of the latex thin film 13 of colloid of inside 14 and appearance, and ultrasonic wave acoustic beam 12 can be transmitted to well in colloid and be positioned at ultrasonic colloid pad surface and smear ultrasonic coupling agent 11, and self-adhering type paster 19 can guarantee that object does not depart from the ultrasonic wave acoustic beam scope in detection and therapeutic process.Ultrasonic colloid pad is fixed on the ultrasonic transducer 18 through connector 15.
It is pointed out that this utility model includes but are not limited to above embodiment, it also can have other conspicuous variations, needs to do accommodation according to the shape of ultrasonic transducer like ultrasonic colloid pad.
