Abstract
Description
Technical Field
[0001] The present application relates to the technical field of fixing devices, for example, to a fixing device for an ultrasonic electrode treatment head. Background Art
[0002] The ultrasound-coupled patch contains a special ultrasonic conductive medium that effectively transmits ultrasonic energy to the skin and tissue beneath it. This allows the drug to quickly enter the bloodstream and achieve the desired therapeutic effect. Therefore, using the ultrasound-coupled patch in conjunction with an ultrasound drug delivery device can enhance drug penetration and therapeutic efficacy, shortening the patient's recovery time.
[0003] Traditional medical ultrasound coupling patches are typically operated by adhesion. This involves first adhering the ultrasound tip to the patch's central circular hole, then placing a solid gel sheet within the central circular hole. Finally, the patch is adhered to the body surface to begin treatment. However, due to the small adhesion area between the ultrasound tip and the patch, the two can easily become detached during treatment, hindering the smooth progress of treatment.
[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0006] An embodiment of the present disclosure provides a fixing device for an ultrasonic electrode treatment head, which is used to prevent the ultrasonic treatment head from falling off from a patch.
[0007] In some embodiments, the ultrasonic electrode treatment head fixing device includes: a patch for adhering to the surface of human skin, the patch including a circular hole at its center; a cylinder connected to the non-adhesive surface of the patch and coaxially distributed with the circular hole, the cylinder including a notch; a cylinder cover threadedly connected to the cylinder; a spline sleeve rotatably installed at the center of the top wall of the cylinder cover; a spline shaft slidably passed through the spline sleeve, one end of the spline shaft is located inside the cylinder cover, and the other end of the spline shaft is located outside the cylinder cover; a pressure plate installed at one end of the spline shaft located inside the cylinder cover; a spring, sleeved on the spline shaft, and located between the pressure plate and the spline sleeve; a limiting ring installed at one end of the spline shaft located outside the cylinder cover.
[0008] Optionally, the cylinder includes an external thread, which is located on the outer side of the cylinder; the cylinder cover includes an internal thread, which is located on the inner side of the cylinder cover, and the internal thread matches the external thread.

[0010] Optionally, it further includes: a bearing installed between the cylinder cover and the spline sleeve, the outer ring of the bearing abuts against the cylinder cover, and the inner ring of the bearing abuts against the spline sleeve.
[0011] Optionally, it further includes: a first elastic retaining ring, which is clamped on the cylinder cover and abuts against the outer ring of the bearing.
[0012] Optionally, it further includes: a second elastic retaining ring, which is clamped on the spline sleeve and abuts against the inner ring of the bearing.
[0013] Optionally, it further includes: a first metal gasket, which is sleeved on the spline shaft and located between the spring and the spline sleeve.
[0014] Optionally, it further includes: a second metal gasket, which is sleeved on the spline shaft and located between the spring and the pressure plate.
[0015] Optionally, it further comprises: a ring connected to the outer wall of the cylinder and connected to the non-adhesive surface of the patch.
[0016] The ultrasonic electrode treatment head fixing device provided in the embodiments of the present disclosure can achieve the following technical effects:
[0017] An embodiment of the present disclosure provides an ultrasonic electrode treatment head fixing device, comprising a patch, a cylinder, a cylinder cover, a spline sleeve, a spline shaft, a pressure plate, a spring and a limiting ring. The patch is used to adhere to the surface of human skin, and the patch includes a circular hole located at its center, and the circular hole is used to accommodate a solid gel sheet. The cylinder is connected to the non-adhesive surface of the patch and is coaxially distributed with the circular hole, and is used to accommodate the ultrasonic treatment head. The cylinder includes a notch, and the notch is used to pass the connecting cable of the electrode treatment head. The cylinder cover is threadedly connected to the cylinder, and the two are detachably mounted. The spline sleeve is rotatably mounted at the center of the top wall of the cylinder cover and can rotate relative to the top wall of the cylinder cover. The spline shaft is slidably inserted into the spline sleeve and can slide relative to the spline sleeve. One end of the spline shaft is located inside the cylinder cover, and the other end of the spline shaft is located outside the cylinder cover. The pressure plate is installed at one end of the spline shaft located inside the cylinder cover, and is used to abut against the ultrasonic treatment head. The spring is mounted on the spline shaft and located between the pressure plate and the spline sleeve, providing elastic force to ensure that the pressure plate only presses the ultrasonic therapy head. A limit ring is installed on the end of the spline shaft outside the barrel cover to prevent the spline shaft from falling out of the spline sleeve.
[0018] During use, after adhering the patch to the surface of human skin, unscrew the tube cover, and then place the solid gel sheet inside the circular hole, and then place the ultrasonic treatment head inside the cylinder. Then screw on the tube cover. Since the spline shaft and the spline sleeve can slide against each other, the spring can be compressed. Then, under the elastic force of the spring, the pressure plate can press the ultrasonic treatment head tightly, so that the solid gel sheet fits tightly against the human skin and the ultrasonic treatment head, thereby performing treatment and preventing it from falling off. In addition, since the spline sleeve and the tube cover can rotate with each other, the pressure plate will not rotate with the rotation of the tube cover, thereby preventing the ultrasonic treatment head from being worn and damaged. After the treatment is completed, the patch part can be directly discarded and the tube cover part can be continuously used to avoid cross infection.
