Description
Technical field
The present invention relates to ultrasonic diagnostic technique fields, and in particular to a kind of application device of ultrasonic wave-coupled agent.
Background technology
Diagnostic ultrasound equipment be by from be built in ultrasonic probe vibrating elements generate ultrasonic pulse, ultrasonic wave
Radiation in continuous wave direction subject, and the ultrasonic wave generated by difference of the vibrating elements by the acoustic impedance because being detected body tissue
Reflection is converted to electric signal, to collect the device of the information in subject in a manner of non-invasive.Ultrasonic diagnosis dress is used
The medical examination set by making ultrasonic probe be contacted with the operation of body surface due to that can easily collect various dynamic images
Data, realtime image data, so being widely used in the morphological diagnosis of internal organs, functional diagnosis.
When ultrasonic examination, the air between probe and patient skin will hinder ultrasonic wave to be passed to human body, to obtain high quality
Image, need fluidity transmitting medium to connect probe and the patient's body surface, this medium is exactly couplant.Use ultrasonic coupling agent
Purpose be first the slight void filled between contact surface, so that these interstitial micro-airs is influenced penetrating for ultrasound;
It is followed by acted on by couplant " transition ", so that the acoustic impedance difference between probe and skin is reduced, exist to reduce ultrasonic energy
The reflection loss at this interface.In addition, also acting as " lubrication " effect, reduce the friction between probe face and skin, keeps probe clever
Sliding living is detected.Fine or not and couplant the uniformity coefficient of couplant and obtained Quality of acoustical image graphic are closely related, generally exist
All it is by being squeezed couplant on the skin, going couplant being put on skin to be measured with probe, do so when use
The disadvantage is that one to smear uniformly, two thickness for carrying out couplant also result in the waste to couplant.Therefore the prior art needs
A kind of application device of couplant has solved defect of the prior art when smearing couplant.
Invention content
The invention is intended to provide a kind of application device of ultrasonic wave-coupled agent, to be coupled when solving prior art ultrasound detection
Uneven and waste defect is smeared in agent.
A kind of application device of ultrasonic wave-coupled agent of the present invention, including fluid reservoir and applying head, the top of the fluid reservoir
Portion is equipped with charge door, and the bottom of the fluid reservoir is connected to applying head, and the applying head includes shell, drive roll and driven voller,
The shell is equipped with fluid reservoir clamping portion, driven voller clamping portion and drive roll clamping portion successively from top to bottom, on the driven voller
Equipped with multiple rows of axially distributed teeth, the shell is equipped with the teeth slot extended towards drive roll engaged with teeth, institute
It states to be equipped at position opposite with teeth on drive roll and squeezes slot, squeeze and be equipped with spring top cap in slot, the spring top cap includes
Plastic lid, key axis and spring, the spring are located in key axis, and plastic lid is located at the top of key axis.
The operation principle of the present invention:The present apparatus includes fluid reservoir and applying head, and wherein fluid reservoir is for loading couplant
, couplant be from charge door feed, exited on applying head by the bottom of fluid reservoir, applying head include shell,
Drive roll and driven voller are equipped with fluid reservoir clamping portion, driven voller clamping portion and drive roll clamping portion successively on the shell, are used for dividing
It Zhuan Zai not fluid reservoir, drive roll and driven voller;Multiple rows of axially disposed teeth are set on driven voller, are provided on shell and tooth
The teeth slot of tooth engagement so that driven voller in the rotation, will not be stopped by shell, be arranged on drive roll and squeeze slot,
It squeezes and spring top cap is set in slot, spring top cap is similar to the form of keyboard, and teeth squeeze plastic lid, and plastic lid squeezes position
In the spring in keyway, so that plastic lid direction is squeezed and moved in slot, the indoor liquid of liquid storage enters drive roll by driven voller
On extruding slot in, smear when, drive roll rolls on the skin of human body, and driven voller also rolls therewith, due to teeth
It is provided in driven voller, so when teeth can only be relied on to rotate from the couplant that fluid reservoir flows out, drive roll is flowed to by teeth slot
Place, and then skin surface is applied to by drive roll;When extruding slot in teeth and drive roll is ratcheting, spring top cap is squeezed by teeth
It is pressed in and squeezes in slot, when teeth eject the couplant in extruding slot under the action of elasticity with spring top cap when slot separates is squeezed
Slot is squeezed, drive roll can be enable to generate couplant in transmission in this way and fill up skin surface and gap, ensure that couplant exists
The uniformity smeared on skin, while also can guarantee that the thickness of couplant is consistent by the rotation of drive roll smearing, it avoids wasting.
Beneficial effects of the present invention:The application device of the ultrasonic wave-coupled agent of the present invention, utilizes drive roll, driven voller, tooth
Tooth, spring top cap and squeeze slot setting, by being rolled in human skin surface so that couplant can smoothly from fluid reservoir into
Enter into the extruding slot of drive roll, and then eject extruding slot because of extruding, so that it is uniformly smeared on the skin, ensure couplant
Thickness it is consistent, avoid wasting.
Further, to be threadedly coupled between the fluid reservoir and fluid reservoir clamping portion, the threaded connection place is equipped with sealing
Gasket.For the ease of loading, realize that the setting of gasket seal is to avoid leakage by being threaded connection.
Further, pressure regulator is equipped in the fluid reservoir.It is indoor that liquid storage is adjusted by the setting of pressure regulator
Pressure accelerates the outflow of couplant.
Further, drive roll clamping portion is equipped with the locking plate of limitation drive roll rotation.When that need not smear
It waits, in order to avoid drive roll rotates so that couplant outflow, is added locking plate limitation drive roll rotation at this time.
Further, the outlet of the fluid reservoir is equipped with heating mantle, and being flowed in the heating mantle has heating fluid.Pass through heating
The flowing of fluid, give couplant heating, winter using when avoid making skin by cold stimulation because temperature is too low.
Further, the outer cover of the drive roll is equipped with sleeve, and the sleeve is equipped with through-hole corresponding with slot is squeezed.
The setting of sleeve is for protecting drive roll.
