Description

Ultrasonic probe and ultrasonic device

Technical Field

The invention relates to the technical field of medical instruments, in particular to an ultrasonic probe and an ultrasonic device.

Background

Various medical ultrasonic devices clinically used utilize the physical characteristics of ultrasonic waves and the difference of acoustic properties of organs and tissues of a part to be tested to display the physiological condition of diseases, in particular to soft tissues. Echocardiography, for example, utilizes the special physical properties of ultrasonic shortwaves to examine the anatomical and functional state of the heart and large blood vessels in the form of waveforms, curves, or images, etc. There are three types of clinical applications: m-mode, two-dimensional, and doppler echocardiography. Echocardiography can also show the velocity and direction of blood flow in a blood vessel using doppler phenomena.

Ultrasound probes are an important component of medical ultrasound equipment. The ultrasonic probe can convert the electric signal sent by the host into an ultrasonic signal with high-frequency oscillation, and also can convert the ultrasonic signal emitted from the organ of the tissue into an electric signal. The collected electric signals of the ultrasonic echo can form corresponding images after being processed by a signal processing device, and the corresponding images are displayed on a display of a host machine. Ultrasound transducers are also an important component of ultrasound probes. The piezoelectric layer in the ultrasonic transducer can generate elastic deformation when being electrically excited, so that ultrasonic waves are generated; in the opposite case, the piezoelectric layer also elastically deforms when ultrasonic waves pass, which in turn causes an electrical signal. Finally, the system processes the electric signals caused by the ultrasonic waves through a signal processing device to finish image exploration of the detected object.

The traditional ultrasonic probe is a rigid structure formed by an ultrasonic transducer, an electrode, a matching layer, a backing layer, a shell and the like, and has a large volume.

When the structure of the part to be detected is probed clinically by the ultrasonic probe, operators such as doctors often need to apply force to the handle of the ultrasonic probe to press the surface of the part to be detected because the surface of the part to be detected is mostly a curved surface, so that the rigid surface of the ultrasonic probe is attached to the surface of the part to be detected, and the probing direction of the ultrasonic probe is controlled. Since an operator is required to operate the positioning on one side when using the ultrasonic probe. Therefore, when the structure of the probing portion is probed for a long time, on one hand, an operator needs to press the surface of the portion to be tested for a long time, and the position of the ultrasonic probe needs to be controlled stably, so that the ultrasonic probe can keep a relatively stable position, and a relatively accurate detection result can be obtained. That is, it is difficult to actually observe the structure of the probe site continuously for a long time clinically, and it is difficult to monitor the patient for a long time by the ultrasonic probe. Moreover, the need for an sonographer to apply force to the handle during the test can also result in deformation and limited movement of the soft tissue, such as the diameter of the vessel and movement of the vessel wall, thereby affecting the results of the investigation.

Referring to fig. 1, fig. 1 shows a schematic view of an ultrasound apparatus in an embodiment of the present invention, an ultrasound apparatus 10 is provided in an embodiment of the present invention, including an ultrasound probe 100, a processor, and an ultrasound imaging and display module. The ultrasonic probe 100 is used for adhering to the surface of the part to be measured, sending ultrasonic signals to the part to be measured and receiving echo signals reflected by the part to be measured. The echo signal may specifically be, for example, an echo signal of a central vascular system and a cardiac reflection ultrasound signal. The processor is used for processing the echo signals fed back by the ultrasonic probe 100. The ultrasonic imaging and display module is used for outputting the detection result of the ultrasonic probe 100. Specifically, the ultrasound probe 100, the processor, and the ultrasound imaging and display module are connected in sequence. After receiving the echo signal from the part to be measured, the ultrasonic probe 100 transmits the echo signal to the processor for processing through the ultrasonic receiving and transmitting circuit. The processor then transmits the processing results to the ultrasound imaging and display module. The ultrasonic imaging and displaying module displays the detection result of the processed ultrasonic probe 100 in the form of images and/or parameters, so as to facilitate visual observation of various parameters of the human body. In the above-described embodiments, parameters that the ultrasound probe 100 can detect may include, but are not limited to, directly measurable vessel diameter, vessel wall movement, and blood flow velocity and direction, etc.; indirectly measurable ejection fraction, blood pressure, blood flow throughput, peripheral vascular resistance, etc.

Referring to fig. 2, in one embodiment, the ultrasonic probe 100 includes an ultrasonic transducer assembly 120 and a fixed base 110, and the ultrasonic transducer assembly 120 is disposed inside the fixed base 110. The fixing base 110 is an adhesive body for fixing the ultrasonic transducer assembly 120 to the site to be measured. The ultrasonic transducer assembly 120 is disposed inside the fixing base 110, and the fixing base 110 is a viscous body, so that the ultrasonic transducer assembly 120 can be kept relatively fixed with respect to the portion to be measured by the fixing base 110. Thus eliminating the need for an operator to control the position of the ultrasonic probe 100 for a long time to reduce the work intensity of the operator. On the other hand, the ultrasonic probe 100 is passively adhered to the surface of the portion to be detected, so that the deformation of soft tissues such as blood vessels of the portion to be detected is not caused, the influence on the detection result due to the soft tissue deformation of the blood vessels can be avoided, and the effectiveness and the accuracy of the detection result are improved.

In one embodiment, the ultrasonic probe 100 is adhered to the surface of the site to be measured for a period of time greater than 48 hours. It should be emphasized that the attachable ultrasonic probe 100 also has a function of continuously detecting a human body parameter for a long time based on its ability to passively adhere to the surface of a site to be detected. That is, the ultrasonic probe 100 can realize long-time monitoring of intensive care patients and other people in need thereof by detecting human parameters for a long time. Specifically, since the ultrasonic probe 100 can be adhered to a certain place on the body surface of the human body for a long time, the blood throughput in a certain place in the human body can be continuously known. Thus, by continuously knowing the blood throughput (i.e., the local blood flow) of a certain portion of the human body, the cardiac output of the target subject can be known and continuously detected. Specifically, the change in the diameter of the venous blood vessel and the change in the diameter of the arterial blood vessel can be continuously observed. The motion change trend of the arterial vessel wall can be used for estimating the change trend of human body fluid and peripheral resistance, so that continuous and multi-parameter quantitative analysis of the whole human body hemodynamics is realized. Parameters such as the trend of the total body fluid change are of great importance in the medical field. Specifically, for example, after a surgical operation, a doctor can know the change trend of body fluid of a patient by observing the change trend of the total blood volume of the patient, and accurately and quantitatively supplements liquid for the patient before, during and after the operation according to the change trend of the body fluid of the patient, so that complications related to the operation are reduced, the success rate of the operation is improved, and the postoperative recovery state of the patient is improved.

The cardiac output refers to the total amount of blood ejected from a side ventricle per minute, is the product of heart rate and stroke volume, and is a key clinical index for describing the functional state of the cardiovascular system. In clinic, particularly in operating rooms, ICU, cardiac or vascular interventions, cardiac output or stroke volume can help medical personnel to learn the heart function of a patient, while continuous monitoring of changes in cardiac output helps to obtain immediate changes in cardiac output, so continuous monitoring and rapid response to cardiac output or stroke volume is of particular importance. The calculation of cardiac output from local blood flow is a more conventional calculation in the medical field and will not be described in detail here.

It should be understood that the length of time that the ultrasonic probe 100 is adhered to the surface of the site to be measured can be adjusted according to actual requirements. Specifically, for example, the ultrasonic probe 100 may be adhered to the surface of the site to be measured for 12 hours, 72 hours, 96 hours, 1 week, or even 2 weeks to achieve long-time monitoring of the target object. Of course, the ultrasonic probe 100 may be adhered to the surface of the portion to be measured for any other period of time, which is not limited herein. It should be understood that the above specific examples regarding the length of time that the ultrasonic probe 100 can be adhered to the surface of the site to be measured are not limiting to the length of adhesion. In particular, in practice, the ultrasonic probe 100 is adhered to the body surface of a patient based on the skin condition, age, and other factors of the patient. Resulting in the ultrasound probe 100 adhering to different patients, the adhering time will also change accordingly. In this embodiment, the length of time that the ultrasonic probe 100 is attached to the surface of the portion to be detected is only required to satisfy the actual monitoring requirement. Specifically, for example, if it is necessary to monitor the parameters of the patient in clinical surgery, the time for the ultrasonic probe 100 to adhere to the body surface of the patient may be longer than the expected time for surgery, or the time for the adhesion may be longer than the expected time for surgery plus the time for post-surgery observation. For example, if the operation time period is expected to take 10 hours and the observation time period is 24 hours after the operation, the adhesion time period of the ultrasonic probe 100 may be set to be longer than 30 hours to satisfy the monitoring requirement. Moreover, the connection monitoring can be realized for a longer time by replacing the ultrasonic probe 100.

It should be understood that the above-described embodiments do not limit the ultrasonic probe 100 to continuously detect only the portion to be detected. The ultrasonic probe 100 may also intermittently detect a portion to be detected and a target object, specifically for example: the ultrasonic probe 100 may be provided only for detecting various parameters and the like of the target object at night. Of course, the ultrasonic probe 100 may be configured to intermittently detect the target object with some other time period as an interval time period according to the actual detection requirement, which is not limited herein.

Referring again to fig. 2, in one embodiment, the stationary base 110 is a flexible body. The skin surface of the human body almost presents a curved surface profile, namely the surface of the part to be measured has a certain bending degree. By setting the fixing base 110 to be a flexible body, the fixing base 110 can be attached to the part to be detected more, so that the stability and the continuity of the detection of the ultrasonic probe 100 are improved relatively.

Referring to fig. 2 in combination with fig. 3, in one embodiment, ultrasonic transducer assembly 120 comprises a multi-element ultrasonic assembly 121. The multi-element ultrasonic assembly 121 includes at least one single-element ultrasonic assembly 122, and the at least one single-element ultrasonic assembly 122 is disposed inside the fixed base 110. The single-element ultrasound assembly 122 is configured to transmit ultrasound signals and receive echo signals. Specifically, when the ultrasonic probe 100 is attached to the surface of the portion to be measured, the at least one single-array element ultrasonic assembly 122 is capable of sending an ultrasonic signal to the portion to be measured and receiving an echo signal reflected back from the portion to be measured. And performing ultrasonic detection on the part to be detected.

Referring again to fig. 2 in conjunction with fig. 3, in one embodiment, the multi-element ultrasound assembly 121 includes a plurality of single-element ultrasound assemblies 122. The plurality of unit ultrasonic assemblies 122 are spaced apart within the stationary matrix 110. By arranging a plurality of single-array-element ultrasonic assemblies 122, the plurality of single-array-element ultrasonic assemblies 122 can be distributed in the fixed base 110 at intervals. In this way, when the ultrasonic probe 100 is attached to the surface of the portion to be tested, the plurality of single-array-element ultrasonic assemblies 122 can cover the surface of the portion to be tested. Thus, the plurality of single-array-element ultrasonic assemblies 122 can transmit ultrasonic signals to the to-be-detected part from different positions, and detect the to-be-detected part from the plurality of positions together. In this way, without moving the ultrasonic probe 100 to repeatedly correct the position of the ultrasonic probe 100 relative to the portion to be detected, a better detection result can be obtained through the multi-position detection of the plurality of single-element ultrasonic assemblies 122.

Further, since the single-array-element ultrasonic assemblies 122 can send ultrasonic signals and receive echo signals relatively independently, by setting the sending time of the ultrasonic signals of different single-array-element ultrasonic assemblies 122, the ultrasonic signals sent by different single-array-element ultrasonic assemblies 122 can reach a certain position of the to-be-detected part at the same time. Thereby realizing ultrasonic focusing of the phased array at the position so as to improve the intensity of ultrasonic signals and echo signals, thereby improving the quality of measurement results and enabling the measured image to have higher resolution. Specifically, for example, one of the single-array element ultrasonic assemblies 122 may first send an ultrasonic signal to the to-be-measured portion, and after a period of time, another or another plurality of single-array element ultrasonic assemblies 122 send an ultrasonic signal to the to-be-measured portion, so that the ultrasonic signals that occur sequentially arrive at the to-be-measured portion at the same time, thereby forming a stacked focus. The sequence of generating the ultrasonic signals and the delay time are determined by the distance and the position relationship between the ultrasonic assembly 122 and the to-be-measured part. The above-described sequence of occurrence of the ultrasonic signals and the above-described time of delay may be calculated by an algorithm used in conjunction with the ultrasonic probe 100.

In connection with the above embodiment, since the multi-element ultrasonic assembly 121 includes the plurality of single-element ultrasonic assemblies 122 that are spaced apart, the single-element ultrasonic assemblies 122 can transmit ultrasonic signals and receive echo signals relatively independently. Thus, by providing the fixed substrate 110 as a flexible body, any one of the multi-element ultrasound assemblies 121 and the single-element ultrasound assembly 122 can be better adhered to the skin surface. That is, each single-element ultrasound assembly 122 can be provided with a suitable detection location.

Referring to fig. 4, in one embodiment, the ultrasound device 10 further includes an ultrasound receive transmit circuit 200. The ultrasonic receiving and transmitting circuit 200 is connected with the ultrasonic probe 100 and the processor, respectively. The ultrasonic receiving and transmitting circuit 200 is used for transmitting an excitation signal to the ultrasonic probe 100 and transmitting an echo signal transmitted by the ultrasonic probe 100 to the processor. Specifically, the ultrasonic receiving and transmitting circuit 200 includes a flexible wire 210, and the plurality of single-element ultrasonic assemblies 122 are electrically connected through the flexible wire 210. Since the plurality of single-element ultrasonic assemblies 122 are electrically connected by wires. Thus, setting the wires as flexible wires 210 can reduce the influence of the plurality of single-element ultrasound assemblies 122 on each other's position. Specifically, when the ultrasonic probe 100 is attached to the surface of the portion to be measured, since the skin surface of the portion to be measured is mostly curved, the use of the flexible wire allows the positional relationship between the plurality of unit ultrasonic modules 122 to be set on the surface of the portion to be measured relatively independently without being affected by each other, as compared with the use of the hard wire. Meanwhile, the limitation effect of the hard wire on the attaching and fixing effect of the fixing base 110 can be avoided, so that the ultrasonic probe 100 can be attached to the surface of the part to be detected for a long time, and long-time detection is facilitated.

Referring to fig. 2 in combination with fig. 3, in one embodiment, the plurality of single-element ultrasonic assemblies 122 may be distributed in a straight line, or the plurality of single-element ultrasonic assemblies 122 may be distributed in a rectangular shape, or the plurality of single-element ultrasonic assemblies 122 may be distributed in a quincuncial shape. By arranging a plurality of single-array element ultrasonic assemblies 122 in a straight line, rectangular, circular or quincuncial distribution, the ultrasonic probe 100 can cover the surface of the part to be detected more comprehensively, so that a better detection result is obtained. It should be understood that the above positional relationships of the plurality of single-element ultrasonic assemblies 122 are not limited to the positional relationships thereof, and the positional relationships are merely illustrated to facilitate understanding of the distribution of the plurality of single-element ultrasonic assemblies 122. The positional distribution relationship of the plurality of single-element ultrasonic assemblies 122 can be set according to different requirements, which is not limited herein. Specifically, for example, a plurality of single-array element ultrasonic assemblies 122 may be arranged to be distributed circularly, or a plurality of single-array element ultrasonic assemblies 122 may be arranged to have different position distribution relations according to the special shape of the detection part, or according to the general distribution of the vascular line to be detected.

Referring to fig. 2 and 3, in one embodiment, the spacing between adjacent two single-element ultrasound elements 122 is less than 10mm. Since the smaller the interval between adjacent two single-element ultrasonic components 122, i.e., the greater the number of single-element ultrasonic components 122 per unit area, in the area covered by the ultrasonic probe 100, the higher the accuracy of the detection by the ultrasonic probe 100. In particular, the spacing between adjacent two single-element ultrasound assemblies 122 may be between 1mm and 5mm. The ultrasonic probe 100 can have high detection accuracy by setting the above-described interval to be less than 5mm. Setting the above-mentioned interval to be larger than 1mm can prevent adjacent two single-element ultrasonic assemblies 122 from affecting each other's position. The position where the two single-element ultrasound assemblies 122 affect each other refers to: although the fixing base 110 and the wire are flexible, in practical application, if the interval between two adjacent single-array-element ultrasonic assemblies 122 is smaller, the fixing base 110 and the wire between them may not be sufficiently deformed within the deformation limit thereof, which may cause the ultrasonic probe 100 to be insufficiently adapted to the skin surface. That is, by setting the interval between the adjacent two single-array element ultrasonic assemblies 122 to be 1mm to 5mm, the ultrasonic probe 100 can be sufficiently attached to the skin surface on the basis of ensuring the detection accuracy of the ultrasonic probe 100, so that the detection accuracy can be further improved. With reference to fig. 2 and 3, it should be understood that the above-mentioned interval refers to the distance in the X direction in fig. 2 and 3.

It should be understood that the intervals between the plurality of single-element ultrasonic assemblies 122 are uniformly distributed, and different intervals between the plurality of single-element ultrasonic assemblies 122 can be set according to actual requirements so as to adapt to the to-be-detected position, which is not limited herein.

Referring to fig. 5, in one embodiment, the ultrasonic transduction assembly 120 includes an ultrasonic transducer 122a, an excitation electrode 122b, and a common electrode 122c. Specifically, in connection with the above-described embodiments, the ultrasonic transduction assembly 120 includes a single-element ultrasonic assembly 122, and the single-element ultrasonic assembly 122 includes the above-described ultrasonic transducer 122a, excitation electrode 122b, and common electrode 122c. Excitation electrode 122b is coupled to ultrasound transducer 122a, excitation electrode 122b being configured to provide an excitation signal to ultrasound transducer 122a to cause ultrasound transducer 122a to generate an ultrasound signal, excitation electrode 122b also being configured to be coupled to a processor. The common electrode 122c is connected to a side of the ultrasonic transducer 122a remote from the excitation electrode 122b, and the common electrode 122c is configured to be connected to a processor to form an electrical circuit with the excitation electrode 122b and the ultrasonic transducer 122a.

In the above embodiment, referring to fig. 4, the ultrasonic receiving and transmitting circuit 200 further includes a control circuit board 220. The control circuit board 220 is connected to the single-element ultrasound assembly 122 via the flexible wires 210 described above. Specifically, the control circuit board 220 is connected to the excitation electrode 122b through the flexible wire 210, and the control circuit board 220 can send electric excitation to the excitation electrode 122b through the flexible wire 210. The excitation electrode 122b transmits the electrical excitation sent by the control circuit board 220 to the ultrasonic transducer 122a. So that the ultrasonic transducer 122a generates an ultrasonic signal under the effect of the electrical excitation and emits the ultrasonic signal toward the site to be detected. The single-element ultrasound assembly 122 can then receive the echo signals from the human body and transmit the echo signals to the processor to complete a single detection. It should be understood that the principle and means of the ultrasonic transducer 122a generating an ultrasonic signal and the single-array element ultrasonic assembly 122 receiving an echo signal are common technical means in the ultrasonic field, and will not be described herein.

Further, in the above embodiment, the single-element ultrasound assembly 122 is capable of relatively independently transmitting an ultrasound signal and receiving a echo signal. The control circuit board 220 is thus able to use the preferred echo signals from the one or more single element ultrasound assemblies 122, either automatically or under the input control of a professional, and communicate the signals to the processor. The processor performs signal processing on the signals to obtain optimal images and measurement parameters. The above-mentioned preferred echo signal refers to a signal which is less disturbed or has a clear and stable detection result in the echo signal.

Referring to fig. 4, in one embodiment, the ultrasound device 10 further includes a conductive adhesive film 230. The conductive adhesive film 230 is connected between the ultrasonic probe 100 and the processor, and the conductive adhesive film 230 is a flexible body. Specifically, the ultrasonic receiving and transmitting circuit 200 includes the conductive adhesive film 230, the conductive adhesive film 230 is used for connecting the flexible wire 210 and the control circuit board 220, and the conductive adhesive film 230 is a flexible body. So set up, for conventional electrically conductive wire, can reduce the influence of electrically conductive wire's adhesion effect to ultrasonic probe 100 through flexible electrically conductive glued membrane 230, make ultrasonic probe 100 can more stable adhesion be in the surface of waiting the position of detecting, be convenient for monitor the people continuously. The conductive adhesive film 230 may be an anisotropic conductive adhesive film 230.

Referring again to fig. 5, in one embodiment, the ultrasonic transduction assembly 120 further includes a sound absorbing layer 122d. The sound absorbing layer 122d is connected to a side of the ultrasonic transducer 122a remote from the site to be measured. In connection with the above embodiment, the ultrasonic transducer 122a generates an ultrasonic signal under the effect of the electric excitation, but since the ultrasonic signal generated by the ultrasonic transducer 122a propagates toward at least the near-to-be-measured site and away from the-to-be-measured site. By providing the sound absorbing layer 122d to be connected to a side of the ultrasonic transducer 122a remote from the site to be measured, a part of the ultrasonic wave can be absorbed, and the ultrasonic wave of the part is prevented from interfering with the ultrasonic signal propagated to the site to be measured and from interfering with the echo signal.

Referring again to fig. 5, in one embodiment, the single-element ultrasound assembly 122 further includes a conductive adhesive layer 122e. The excitation electrode 122b and the ultrasonic transducer 122a are connected by a conductive adhesive layer 122e. The sound absorbing layer 122d is also connected to the ultrasonic transducer 122a by a conductive adhesive layer 122e. The sound absorbing layer 122d has conductivity, and thus a circuit can be formed between the excitation electrode 122b and the common electrode 122c.

Referring to fig. 6, in one embodiment, the sound absorbing layer 122d may not have conductivity. In the present embodiment, by providing the conductive adhesive layer 122e around the sound absorbing layer 122d, a loop can be formed between the excitation electrode 122b and the common electrode 122c.

It should be appreciated that the single-element ultrasound assembly 122 also includes prior art backing layers and acoustic lenses to improve the accuracy of the detection by the ultrasound probe 100 or to reduce interference during the detection by the ultrasound probe 100.

Referring to fig. 2 and 3, in one embodiment, the fixing base 110 includes a first base 111 and a second base 112 connected to the first base 111. The first substrate 111 and the second substrate 112 are flexible bodies, and the first substrate 111 and/or the second substrate 112 are adhesive bodies. By arranging the first substrate 111 and the second substrate 112 to be flexible bodies, the ultrasonic probe 100 can be better attached to the surface of the part to be detected, so as to obtain a more accurate detection result. Further, since the first substrate 111 and the second substrate 112 are connected, it is ensured that the ultrasonic probe 100 can be attached to the site to be measured by using an adhesive body as one of the first substrate 111 and the second substrate 112.

Referring again to fig. 2 and 3, in one embodiment, the ultrasonic transducer assembly 120 is disposed between the first substrate 111 and the second substrate 112. And the projection of the first substrate 111 onto the second substrate 112 can cover the projection of the ultrasonic assembly onto the second substrate 112. In other words, in the present embodiment, by providing the first substrate 111 and the second substrate 112 that are connected to each other, the ultrasonic assembly is provided between the first substrate 111 and the second substrate 112. That is, the ultrasonic transduction assembly 120 is "sandwiched" between the first and second substrates 111 and 112 such that the ultrasonic transduction assembly 120 remains relatively fixed to the first and second substrates 111 and 112. And the first substrate 111 and/or the second substrate 112 are/is made to be an adhesive body, so as to be attached to the surface of the portion to be measured. Thus, the ultrasonic transduction assembly 120 and the part to be measured can be kept relatively fixed, and the working strength of medical staff is reduced. Meanwhile, the passive adhesion fixing mode is adopted, the part to be detected is not required to be pressed, soft tissues such as skin, subcutaneous blood vessels and the like are not deformed, and therefore accuracy of detection results is guaranteed.

Referring again to fig. 2 and 3, in one embodiment, the first substrate 111 is connected to the second substrate 112 for fixing the ultrasonic transducer assembly 120. The second substrate 112 is an adhesive body so that the ultrasonic transducer 120 is fixed relative to the surface of the portion to be measured, and the projection of the second substrate 112 on the surface of the portion to be measured can cover the projection of the first substrate 111 on the surface of the portion to be measured. In other words, in the present embodiment, the second substrate 112 is larger in size than the first substrate 111 in the X-Y plane, and the second substrate 112 is a viscous body. The second substrate 112 may be located at a side of the ultrasonic probe 100 near the to-be-detected portion, so that the size of the second substrate 112 on the X-Y plane is larger than that of the first substrate 111, so that the ultrasonic probe 100 can be more firmly adhered to the skin surface, and the structures such as the multi-array element ultrasonic assembly 121 are kept fixed relative to the to-be-detected portion, so as to facilitate detection. The second substrate 112 may also be located on a side of the ultrasound probe 100 away from the site to be detected, and since the second substrate 112 has a larger size on the X-Y plane than the first substrate 111, a portion of the projection of the second substrate 112 on the X-Y plane that does not coincide with the projection of the first substrate 111 can be used to adhere to the skin surface to fix the ultrasound probe 100 relative to the site to be detected. The above-mentioned X-Y plane can be approximately regarded as the surface of the site to be detected, i.e., the skin surface.

It should be understood that the dimensions of the first substrate 111 and the second substrate 112 may be the same in the X-Y plane, so that the substrate near the portion to be detected of the first substrate 111 and the second substrate 112 is a viscous body. And the other substrate is coupled to the adhesive substrate so that the ultrasonic probe 100 is fixed with respect to the site to be inspected. Of course, the first substrate 111 and the second substrate 112 may be both adhesive bodies, so as to further ensure that the ultrasonic transducer assembly 120 can be firmly adhered to the surface of the portion to be detected, and maintain stable adhesion for a long time.

Referring to fig. 2 and 3, in one embodiment, the stationary base 110 includes a smooth outer surface. Specifically, the first substrate 111 is taken as an example of a substrate near the portion to be detected in the fixed substrate 110. In this embodiment, the fixing base 110 includes a smooth outer surface means: the side of the first substrate 111 close to the portion to be detected and the side of the second substrate 112 far from the portion to be detected are smooth surfaces. The first substrate 111 has a smooth surface on a side close to the portion to be detected, so as to avoid crushing or scratching human skin when being adhered to the surface of the portion to be detected for a long time, and ensure human health and comfort of a patient. The smooth surface on the side of the second substrate 112 far away from the part to be detected can reduce friction with wearing articles such as clothes of a patient, and on one hand, the stability of long-time adhesion of the ultrasonic probe 100 can be ensured; on the other hand, when the ultrasonic probe 100 is attached to the human body for a long time, the degree of freedom of the patient's movement can be increased, and the convenience of the ultrasonic probe 100 can be improved.

Referring to fig. 2 and 3, in one embodiment, the first substrate 111 and the second substrate 112 each have a sheet-like profile. In the case where the ultrasonic probe 100 has the same volume, by providing the first substrate 111 and the second substrate 112 each having a sheet-like profile, the contact area of the fixing substrate 110 with the skin can be increased to improve the stability of the long-time adhesion of the ultrasonic probe 100. Moreover, compared with the ultrasonic probe 100 with a cylindrical outline in the prior art, the first substrate 111 and the second substrate 112 in the shape of the sheet can be more convenient to adapt to the outline of the skin surface, and the ultrasonic probe 100 can be more convenient to adhere to the part to be detected for a long time.

In one embodiment, the first and second substrates 111 and 112 include rounded edges. When the ultrasonic probe 100 is adhered to the skin surface, since the human skin has a certain flexibility, the edges of the first and second substrates 111 and 112 inevitably come into contact with the skin surface when the patient moves. By providing the first base 111 and the second base 112 to include rounded edges, the first base 111 and the second base 112 can be prevented from stabbing the skin when they are in contact with the skin surface. Thereby enabling to improve the comfort of the patient when the ultrasonic probe 100 is adhered for a long time. The edges are referred to by the arrow labeled K in fig. 2.

Referring to fig. 2 and 3 again, in one embodiment, the first substrate 111 and the second substrate 112 may be flexible films with adhesiveness. Specifically, the ultrasonic probe 100 may be formed by disposing the ultrasonic transducer assembly 120 inside a flexible film having an adhesive property, and fixing the ultrasonic transducer assembly 120 with respect to the film by up-and-down encapsulation.

It should be understood that the connection between the first substrate 111 and the second substrate 112 may be adhesive, integrally formed or other connection, which is not limited herein, and an appropriate connection may be selected according to actual requirements.

Referring again to fig. 2 and 3, in one embodiment, the dimension of the ultrasonic transducer assembly 120 is less than 10mm in the direction from the first substrate 111 to the second substrate 112. The cross-sectional area of the ultrasonic transducer assembly 120 is less than 100 square millimeters in a cross-section perpendicular to the direction of the first substrate 111 to the second substrate 112. Referring to fig. 2 and 3, in the present embodiment, the dimension of the single-array element ultrasonic assembly 122 in the Z direction is smaller than 10mm, and may specifically be 8mm, 7mm, 6mm, 5mm and 4mm. The cross section is an X-Y plane, that is, the size of the single-array element ultrasonic assembly 122 on the X-Y plane is less than 10mm by 10mm, specifically, may be 5mm by 5mm, 4mm by 4mm, 3mm by 3mm, and 2mm by 2mm. In other words, the single-element ultrasound assembly 122 is a micro-single-element ultrasound assembly 122. By such arrangement, the ultrasonic probe 100 can be made small in overall size, so as to be easily adhered to the surface of the part to be detected for a long time, and to be convenient for the patient to move. It should be understood that the single-array element ultrasonic assembly 122 may be provided in other sizes, which are not limited herein and may be provided according to actual needs.

In one embodiment, the ultrasound device 10 further comprises a wireless transmission module (not shown, infra) for transmitting the echo signals to the processor. In this way, the influence of the wire on the position of the ultrasonic probe 100 can be reduced, so that the stability of the ultrasonic probe 100 attached to the surface of the part to be detected can be improved. Specifically, the wireless transmission module may be disposed on the ultrasonic probe 100 and the ultrasonic receiving and transmitting circuit 200, respectively, and wireless transmission of the excitation signal (i.e. electrical excitation) and the echo signal is achieved through the wireless transmission module. In this way, the ultrasonic probe 100 can be arranged on the body surface of the patient relatively independently, so that various parameters of the body of the patient can be conveniently detected for a long time, and the influence of the ultrasonic device 10 on the daily activities of the patient can be reduced.

It will be appreciated that the performance of the ultrasound probe 100, such as sensitivity, frequency, bandwidth, etc., can meet the requirements of actual detection. Specific examples are: the blind area of the ultrasonic probe 100 is not more than 5mm, the measurement depth of human tissue is not less than 3cm, and blood vessels with diameters not less than 3mm can be measured.
