技術說明

1.　一種超音波細胞刺激裝置，包括：至少一超音波傳感器，用以產生震波；以及下蓋，具 有第一面以及相對應於該第一面之第二面，該下蓋包括：凹槽，係自該下蓋之該第一面 向內凹陷；及開口，係設於該下蓋之該第二面並連通該凹槽，其中，該開口之直徑係小 於該凹槽之直徑，而於該凹槽之底部形成有抵接部；其中，該至少一超音波傳感器係設 於該下蓋之該凹槽周圍的該第一面上，俾使該震波從該下蓋之該第一面開始傳遞並延伸 進入該抵接部。 2.　如申請專利範圍第1 項所述之超音波細胞刺激裝置，更包括一上蓋，係部分容設於該下 蓋之凹槽內，且該上蓋之側面設有至少一固定部。 3.　如申請專利範圍第2 項所述之超音波細胞刺激裝置，其中，該上蓋之該至少一固定部用 以將該至少一超音波傳感器夾設固定於該至少一固定部及該下蓋之該凹槽周圍的該第一 面之間。 4.　如申請專利範圍第2 項所述之超音波細胞刺激裝置，更包括一玻璃片，係設於該下蓋之 該凹槽內的該抵接部上，而在該震波傳遞進入至該抵接部時，能於該玻璃片上形成均勻 且可控的聲場。 5.　如申請專利範圍第4 項所述之超音波細胞刺激裝置，其中，該下蓋之該凹槽內的該開口 周圍之該抵接部上係凹陷有容置部，以容置該玻璃片。 6.　如申請專利範圍第5 項所述之超音波細胞刺激裝置，其中，該上蓋具有一凸緣，以在該 上蓋容設於該下蓋之該凹槽內時，利用該凸緣之外側所耦接之O 型環將該玻璃片固定於 該容置部。 7.　如申請專利範圍第4 項所述之超音波細胞刺激裝置，其中，該玻璃片為直徑範圍於10 至 40mm 之間、厚度範圍為0.15 至0.4mm 之間的玻璃圓片。 8.　如申請專利範圍第2 項所述之超音波細胞刺激裝置，其中，該上蓋及該下蓋之材質為白 塑鋼或不鏽鋼之高剛性材質。 9.　如申請專利範圍第1 項所述之超音波細胞刺激裝置，其中，該至少一超音波傳感器係透 過黏合方式設於該下蓋之該第一面上。 1. An ultrasonic cellular stimulation device, comprising: at least one ultrasonic transducer configured for generating a vibration wave; and a lower cap having a first surface and a second surface corresponding to the first surface, and comprising: a recess indenting the first surface of the lower cap; an abutment portion located at a bottom of the recess; and an opening formed in the second surface of the lower cap, the opening being in communication with the recess and having a diameter less than a diameter of the recess, wherein the at least one ultrasonic transducer is disposed on the first surface around the recess of the lower cap, such that the vibration wave is conveyed from the first surface of the lower cap into the abutment portion. 2. The ultrasonic cellular stimulation device of claim 1, further comprising an upper cap partially received in the recess of the lower cap and having at least one fixing portion on a lateral surface thereof. 3. The ultrasonic cellular stimulation device of claim 2, wherein the at least one fixing portion of the upper cap is configured for clamping and fixing the at least one ultrasonic transducer between the at least one fixing portion and the first surface around the recess of the lower cap. 4. The ultrasonic cellular stimulation device of claim 2, further comprising a glass piece disposed on the abutment portion in the recess of the lower cap, wherein a uniform and controllable sound field is formed on the glass piece when the vibration wave is conveyed into the abutment portion. 5. The ultrasonic cellular stimulation device of claim 4, further comprising a reception portion concavely formed on the abutment portion around the opening in the recess of the lower cap and configured for receiving the glass piece. 6. The ultrasonic cellular stimulation device of claim 5, further comprising an O-ring, wherein the upper cap has a flange, and the O-ring is coupled to an outer side of the flange and fixes the glass piece to the reception portion when the upper cap is received in the recess of the lower cap. 7. The ultrasonic cellular stimulation device of claim 4, wherein the glass piece is a round glass piece having a diameter ranging from 10 mm to 40 mm and a thickness ranging from 0.15 mm to 0.4 mm. 8. The ultrasonic cellular stimulation device of claim 2, wherein the upper cap and the lower cap are made of a rigid material. 9. The ultrasonic cellular stimulation device of claim 8, wherein the rigid material is white steel or stainless steel. 10. The ultrasonic cellular stimulation device of claim 1, wherein the at least one ultrasonic transducer is adhered to the first surface of the lower cap.
