[0026] Handle portion 61 , probe portion 62 , and detection end 63 . DETAILED DESCRIPTION

[0027] like Figure 1-4 As shown, an ultrasonic isolation sound-transmitting membrane in this embodiment comprises a first membrane segment 1, a second membrane segment 2 and a third membrane segment 3, wherein the second membrane segment 2 and the third membrane segment 3 are located in the first membrane segment 1, the right side of the first membrane segment 1 is open, the left side of the membrane segment is connected to the left side of the second membrane segment 2, the left side of the third membrane segment 3 is connected to the right side of the second membrane segment 2, the right side of the third membrane segment 3 is a contact end 4, the right side of the third membrane segment 3 is sealed, a restraining sleeve 5 is arranged in the first membrane segment 1, and the restraining sleeve 5 is sleeved on the third membrane segment 3 or on the connection between the third membrane segment 3 and the second membrane segment 2;

[0028] The steps of installing the ultrasonic isolation sound-transmitting membrane on the ultrasonic probe 6 are as follows:

[0029] Step S1, inserting the probe part 62 of the ultrasonic probe 6 into the second membrane segment 2 and the first membrane segment 1 in sequence, and before inserting, applying coupling agent to the detection end 63 of the probe part 62;

[0030] Step S2, when the detection end 63 of the probe part 62 abuts against the inner wall of the contact end 4 of the third membrane segment 3, the first membrane segment 1 is pushed to be sleeved on the handle part 61 of the ultrasonic probe 6, and while pushing the first diaphragm, the restraint sleeve 5 is pushed through the first diaphragm, that is, the restraint sleeve 5 can be sleeved on the handle part 61 of the ultrasonic probe 6 through the first diaphragm, so that the first diaphragm is tightly bound to the handle part;

[0031] After the ultrasonic isolation sound-transmitting membrane is installed on the ultrasonic probe 6, the ultrasonic isolation sound-transmitting membrane is expanded to form a columnar flexible sleeve body;

[0032] In this way, when the probe part 62 of the ultrasonic probe 6 is sequentially extended into the second membrane segment 2 and the first membrane segment 1, the left opening of the second diaphragm facilitates air to enter the second diaphragm segment and the third diaphragm segment. At the same time, as the probe part 62 is extended, the opening side of the first diaphragm segment is opened to facilitate air to enter from the opening of the first diaphragm, thereby avoiding the operation being affected by negative pressure, and avoiding the hand from directly contacting the contact surface between the isolation membrane and the human body to cause contamination. Moreover, the first membrane segment 1 can be fastened to the handle part 61 by only pushing the binding sleeve 5, which is convenient to operate.

[0033] The contact end 4 of the third film segment 3 is rounded to improve the smoothness of the end of the third film segment 3 extending into the human body, and the rounded corners make it easier to fit on the detection end 63 of the probe part 62;

[0034] A coupling agent is arranged in the contact end 4 of the third film segment 3. The coupling agent is placed in the third film segment 3 in advance. When the probe part 62 is inserted into the third film segment 3, the coupling agent is smeared on the detection end 63 of the probe part 62 to prevent the coupling agent from adhering to the inner walls of the second film segment 2 and the third film segment 3 when the probe part 62 is inserted into the second film segment 2 and the third film segment 3, thereby causing waste.

[0035] The restraint sleeve 5 is a rubber band;

[0036] The thickness of the first membrane segment 1, the activity of the second membrane segment 2 and the thickness of the third membrane segment 3 are equal, and the thickness of the first membrane segment 1 is 0.02 mm to 0.04 mm;

[0037] The length of the first film segment 1 is 200 mm to 300 mm;

[0038] The caliber of the first membrane segment 1 is smaller than that of the third membrane segment 3, the caliber of the left side of the second membrane segment 2 is equal to that of the first membrane segment 1, and the caliber of the right side of the second membrane segment 2 is equal to that of the third membrane segment 3;

[0039] The first film segment 1 , the second film segment 2 and the third film segment 3 are all made of transparent materials.

[0040] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
