Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to B ultrasonic probe.

Background

The diagnosis of B-ultrasonic is more and more widely used, and a plurality of hidden focuses can be found in advance, so that patients can be treated in time. In hospitals, the best mode of use of the B-ultrasonic probe is to sterilize the B-ultrasonic probe once for a single person, but the mode of use is difficult to implement strictly, and particularly, the B-ultrasonic probe is applied to an extracorporeal probe on the surface of human skin, and specifically comprises the following steps: if the probe is sterilized once, the accumulated time of sterilization may exceed the service time of the probe, which results in the waste of medical resources; secondly, the number of patients can be diagnosed every day is reduced, which is not beneficial to the timely treatment of the patients and the operation in hospitals. Even such an extracorporeal probe, however, would be highly advantageous for preventing cross-contamination between the patient's skin if it could be sterilized on a regular basis, reducing or even eliminating the risk of cross-contamination of the skin.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model discloses a B-ultrasonic probe, including external probe body, external probe body is including acoustic lens 1, matching layer 2, wafer 3, sound absorption block 4, support frame 5 and the handle portion 5a that sets gradually. Acoustic lens 1: is positioned outside the probe and is directly contacted with the skin of a patient after being coated with the coupling agent in use; matching layer 2: the probe is arranged between the acoustic lens 1 and the wafer 3 array, so that the matching between the in-vitro probe body and the load is realized; the wafer 3, the most important part in the probe, is used for receiving the electric pulse and producing the mechanical ultrasonic vibration, finish acoustoelectric and electro-acoustic conversion work; sound absorption block 4: the ultrasonic energy used for attenuating and absorbing the back radiation of the piezoelectric vibrator; the support frame 5 is an outer shell used for wrapping the acoustic lens 1, the matching layer 2, the wafer 3 and the sound absorption block 4; handle portion 5 a: the right support frame 5 extends out of the part for holding a doctor, and a cable connecting clamping piece is arranged inside the right support frame. In the present solution, improvements are mainly made to the acoustic lens 1 and the matching layer 2.

As shown in fig. 2 and 3: the matching layer 2 and the acoustic lens 1 adopt a detachably fixed sliding connection structure. The method specifically comprises the following steps: two opposite arc edges of the inner arc surface 13 (the upper surface in fig. 2) of the acoustic lens 1 close to the matching layer 2 are integrally formed with arc-shaped flange bodies 11 toward the center of the circle, and the inner side walls (the two opposite side walls in fig. 3) of the two arc-shaped flange bodies 11 are both provided with sliding grooves 1a along the length direction.

As shown in fig. 3, the cross-sectional structure of the matching layer 2 and the acoustic lens 1 after sliding connection is shown, the matching layer 2 is slidably fitted between the two arc-shaped flange bodies 11, sliding portions 2a are integrally formed on both long sides of the matching layer 2 close to the acoustic lens 1, the sliding portions 2a are slidably fitted to the sliding grooves 1a, and the sliding portions 2a can slide back and forth along the long direction of the sliding grooves 1 a.

The acoustic lens 1 and the matching layer 2 adopt the structure, so that the acoustic lens 1 and the matching layer 2 can be rapidly disassembled and assembled. And the acoustic lens 1 is taken as a quick replaceable part, and each set of external probe body comprises at least two acoustic lenses 1. Therefore, when a doctor uses the acoustic lens 1 to work in contact with the skin, the other acoustic lens 1 can be cleaned and disinfected without delay. The whole body of the extracorporeal probe is expensive, but the price of the single acoustic lens 1 is not so expensive. Therefore, the acoustic lens 1 which is in direct contact with the skin of a human body can be cleaned and replaced in turn when the acoustic lens 1 is replaced and not used intermittently, so that the problem that the in-vitro probe cannot be sterilized locally and timely is solved, and the problem that too much time is spent in sterilization is solved.

Of course, the number of acoustic lenses 1 is large, and the acoustic lenses 1 should be housed by an outer casing 6 as shown in fig. 4, so as to prevent the acoustic lenses 1 from being damaged. The outer shell 6 comprises at least two concave containing cavities 6a, the containing cavities 6a are matched with the shapes of the acoustic lenses 1, and one containing cavity 6a is used for containing one acoustic lens 1; each of the receiving chambers 6a has a replacement port 6c formed in a side wall thereof for allowing the body of the outer probe to enter therethrough.

It should be noted that: the connection between the acoustic lens 1 and the matching layer 2 in the present case is made in a detachable manner by a sliding connection. Thus, the outer sheath 6 is provided with a replacement opening 6c for passing through the body of the extracorporeal probe. The external probe body directly slides into the containing cavity 6a from the replacing port 6c, and then the connection of the acoustic lens 1 can be completed at one time. For the link structure, as shown in fig. 2, in the present application, another limit structure is further provided to increase the connection speed.

A straight flange body 12 is integrally formed on one straight edge of the acoustic lens 1 close to the inner arc surface 13 of the matching layer 2 in the direction of the center of the circle, and the sliding groove 1a extends to the straight flange body 12. When the in vitro probe body slides through the sliding chute 1a, after the matching layer 2 is abutted to the straight flange body 12, the relative position relationship between the matching layer 2 and the raw lens meets the preset requirement, and the matching layer 2 slides in place. This facilitates a quick mounting of the acoustic lens 1 and the matching layer 2.

We know that: when the existing in-vitro probe body is used, a couplant needs to be smeared on the skin of a human body. In view of the above, the present disclosure is also directed to improvements. As shown in fig. 3 and 4: the bottom of the accommodating cavity 6a is provided with a liquid medicine groove 6b, and the liquid medicine groove 6b can contain a couplant. After the cleaning is completed, the acoustic lens 1 is loaded into the housing chamber 6 a. Since the coupling agent itself has a certain viscosity. Therefore, when the couplant is placed in the chemical liquid tank 6b and the acoustic lens 1 is placed in the housing chamber 6a, the surface (lower surface shown in fig. 3) of the acoustic lens 1 remote from the matching layer 2 is directly contacted with the couplant, so that the couplant sticks to the acoustic lens 1. When the external probe body is provided with the acoustic lens 1, the acoustic lens 1 can be used for kneading the couplant in the sliding process of the acoustic lens 1 relative to the matching layer 2, so that the couplant can be uniformly adhered to the acoustic lens 1, a doctor can smear the couplant during examination, and the B-ultrasonic examination time can be saved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
