Wherein, the bag-shaped body 12 is mushroom-head-shaped and comprises an arc bottom c2 and an arc side wall c1; the bottom of the pouch 12 is provided with a plurality of leakage holes 13, the leakage holes 13 to slowly permeate the coupling medium 40 in the pouch 10 to the skin k of the patient, and the diameter of the leakage holes 13 ranges from 0.1 to 0.001 mm. The bottom of the bag-shaped body 12 can be fully contacted with the skin of a patient, so that air residues are avoided, and burn of ultrasonic waves to the patient is avoided.
In the actual operation process, the leakage holes 13 slowly permeate the liquid coupling medium 40 in the capsule body 10 outwards, and spread along the contact surface of the outer wall of the capsule and the skin k, so that trace air between the skin k and the outer wall of the capsule is expelled;
when the ultrasonic treatment head 50 moves in the liquid coupling medium 40, the liquid coupling medium 40 in the cylindrical body 11 and the bag-shaped body 12 can bidirectionally flow along with the change of the liquid pressure, so that the shape of the mushroom-head-shaped bag-shaped body 12 is kept stable.
The weep holes 13 at the bottom of the pocket 12 are distributed in a plurality of concentric rings, with the density of weep holes distributed on the inner ring being greater than the density of weep holes 13 distributed on the outer ring.
After the coupling medium is filled in the bag body 10, the diameter of the contact area between the bottom of the bag-shaped body 12 and the skin k of the patient ranges from 5 mm to 100mm, and the leakage holes 13 are distributed at the contact part of the bag-shaped body 12 and the skin k of the patient. For the treatment of the diseased organ in the human body, the diameter of the contact area between the bottom of the pouch-like body 12 and the skin k of the patient is preferably controlled to be 10-100mm.
For use in cosmetic devices, the diameter of the contact area is preferably controlled in the range of 5-100mm.
The tapered portion 16 includes an upper constant diameter portion d1 and a lower tapered portion d2, the tapered portion d2 having a diameter smaller than that of the tubular body 11, the tubular body 11 transits to the constant diameter portion d1 through the tapered portion d2, and the constant diameter portion d1 borders the upper edge of the bag-like body 12; the pinch portion 16 facilitates the flow of the liquid coupling medium 40 between the cartridge 11 and the pouch 12.
A shrinkage part 16 is arranged between the cylindrical body 11 and the bag-shaped body 12, after the liquid coupling medium is injected, the bottom of the bag-shaped body 12 can be ensured to be fully contacted with the skin of a patient, and air residues between the outer wall of the bag and the skin are avoided; in addition, the joint surface of the medium bag and the skin can be always larger than the ultrasonic energy emission area of the ultrasonic treatment head, so that the area occupied by high-energy ultrasonic penetrating the skin can be safely covered, and the skin of a patient can be prevented from being burned by ultrasonic energy.
The upper part of the cylinder 11 is provided with a connector d3, and the connector d3 is used for connecting with the ultrasonic treatment head shell. The capsule body 10 is made of silicone rubber, organic polymer material or nano material.
In use, when the ultrasonic treatment head 50 moves in the direction of the skin k, the liquid in the bag-like body 12 is pressed to flow to the upper cylindrical body 11; when the ultrasonic treatment head 50 moves away from the skin k, the liquid in the bag-like body 12 is less pressurized, and the liquid in the cylindrical body 11 is urged to flow toward the bag-like body 12.
An ultrasound treatment method comprising the steps of: 1) The ultrasound-transmitting thin film media bladder 100 is filled with a liquid coupling medium 40; 2) The ultrasound therapy head 50 is placed in the liquid coupling medium 40 of the medium bladder; 3) When ultrasound energy is emitted from the ultrasound therapy head 50 to the lesion of the patient, the liquid coupling medium 40 in the medium bladder slowly permeates through the leakage orifice 13 onto the skin k of the patient during the entire course of the ultrasound therapy.
In operation, the weep holes 13 slowly permeate the liquid coupling medium 40 in the bladder 10 outwardly, spreading along the interface of the bladder outer wall with the skin k, thereby expelling air between the skin k and the bladder outer wall.
When the ultrasonic treatment head 50 moves in the liquid coupling medium 40, the liquid coupling medium 40 in the cylindrical body 11 and the bag-shaped body 12 can bidirectionally flow along with the change of the liquid pressure, so that the shape of the mushroom-head-shaped bag-shaped body 12 is kept stable.
Specifically, the back of the ultrasound therapy head 50 is connected to a mechanical arm k, and the medical staff controls the ultrasound therapy head 50 to work by controlling the mechanical arm k. When the ultrasonic treatment head 50 moves toward the skin, the liquid in the bag-like body 12 is pressed to flow toward the upper cylindrical body 11; when the ultrasound therapy head 50 moves away from the skin, the liquid in the pouch 12 is less pressurized, causing the liquid in the cartridge 11 to flow in the direction of the pouch 12. I.e. the bottom of the pouch 12 can be in full contact with the patient's skin, avoiding air residues and avoiding burn of the patient by ultrasound.
After the liquid coupling medium 40 is filled in the bag body 10, the diameter of the contact area between the bottom of the bag-shaped body 12 and the skin of the patient ranges from 5 mm to 100mm, and the leakage holes 13 are distributed at the contact part of the bag-shaped body 12 and the skin of the patient.
For the permeation holes 13, the bottom of the medium bag is provided with a plurality of permeation holes 13, and the permeation holes 13 slowly permeate the coupling medium 40 in the bag body 10 to the skin k of the patient; the tension of the coupling medium 40 allows for a better fit of the bottom of the medium bladder to the patient's skin, enhances the coupling of the medium water to the patient's skin, avoids the ultrasonic energy from burning the patient's skin, and achieves a better therapeutic experience.
In the description of the present invention, it should also be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "coupled," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The foregoing has outlined rather broadly the principles and embodiments of the present invention in order that the detailed description of the invention may be better understood with respect to the present application in conjunction with an ultrasound-transmitting thin film media balloon and ultrasound therapy device. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
