Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasonic probe and ultrasonic measuring device. Background Technology

[0002] Doppler ultrasound technology offers the advantages of being non-invasive, real-time, and accurate in monitoring cardiac hemodynamics. When performing non-invasive ultrasound blood flow monitoring using a Doppler probe, the probe needs to be fixed to a specific location on the patient (e.g., neck or wrist). Therefore, before starting monitoring, medical staff need to manually adjust the probe to a suitable monitoring position and secure it for extended monitoring, or apply pressure for brief monitoring. During prolonged monitoring, if the probe or blood vessel position changes, the probe's position needs to be adjusted until a suitable monitoring location is found.

[0003] In related technologies, a butterfly-shaped probe is commonly used, with a narrow square top and sloping smooth surfaces extending from the top to the bottom. However, this probe design makes it inconvenient for medical staff to handle or move, resulting in poor ease of use and comfort, and making it difficult to move the probe to find a suitable monitoring position.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] In existing technologies, butterfly-shaped probes are commonly used, with a narrow, square top and smooth, sloping sides extending from the top to the bottom. However, when manual adjustment of the probe's fixed or monitoring position is required, this design makes it very inconvenient for medical staff to handle or move it. The probe's adjustability and ease of use are poor, making it difficult to move the probe to find a suitable monitoring position. When medical staff need to press the probe for brief monitoring, the narrow, square top of the probe is quite protruding, which can even cause discomfort to the fingers when pressing the probe, and the user posture often involves a twisted wrist, resulting in poor comfort.

[0040] In response to this problem, this utility model proposes an ultrasonic probe to solve the aforementioned issues.

[0041] Reference Figure 1 and Figure 2In one embodiment of this utility model, the ultrasonic probe includes a housing body 10 and an ultrasonic transducer (not shown in the figure); the housing body 10 is provided with a pinching part 11, which is a recessed structure adapted to conform to the shape of a human finger; the ultrasonic transducer is disposed inside the housing body 10 and is adapted to be electrically connected to the ultrasonic host for transmitting and receiving ultrasonic signals. The ultrasonic transducer can be a wafer or a wafer assembly.

[0042] In this embodiment, the ultrasound probe can be used for measuring devices that monitor blood flow, etc., and can be a Doppler ultrasound device or other medical monitoring device, which is not limited here.

[0043] In this embodiment, the shell body 10 is an integral structure, meaning it can be a single component; of course, it can also be a modular structure, assembled from two or more components, which is not limited herein. The recessed structure can be provided on two opposite sides of the shell body 10 away from the ultrasonic transducer to facilitate pinching and pressing operations by the operator.

[0044] It is understood that this invention improves the housing structure of the ultrasound probe. By providing a gripping part 11 with a recessed structure adapted to the shape of a human finger, the comfort and convenience of operating the ultrasound blood flow probe are effectively improved, making gripping, moving, and locating more convenient and efficient. In addition, the recessed structure can also save material usage to a certain extent and reduce the size of the ultrasound probe.

[0045] In one embodiment, primarily referring to Figure 1 and Figure 3 The top surface of the shell body 10 has a first arc 101 at its top along the length direction of the ultrasonic probe (i.e., the X-axis direction shown in the figure). The first arc 101 tends to be low in the middle and high on both sides.

[0046] In other words, viewed from the front of the ultrasound probe shown in the figure, the top surface of the shell body 10 in this embodiment is an arc-shaped surface with a concave center and convex sides. This design helps to increase the contact area between the curved surface of the probe waist and the fingers when using the ultrasound probe, making it easier for medical staff to pinch the probe with their fingers to find a suitable measurement position, while also making the probe more stable to hold and less likely to slip out of their hands.

[0047] In one embodiment, primarily referring to Figure 1 and Figure 4 The top surface of the shell body 10 has a second arc 102 at its top along the width direction (i.e., the Y-axis direction shown in the figure) of the projection contour of the ultrasonic probe. The second arc 102 tends to be high in the middle and low on both sides. In this embodiment, the recessed structure is located on both sides of the first arc 101 and in the middle of the second arc 102.

[0048] In other words, viewed from the side of the ultrasound probe shown in the figure, the height of the front and rear sides of the top surface of the shell body 10 in this embodiment is lower than the height of the central recess. By setting this structure, combined with the aforementioned protrusions on the left and right sides, the curved surface formed by the top surface can better fit the arc formed by the thumb and its joint when the medical staff presses, which is more in line with human mechanics and makes the medical staff more comfortable when pressing. This avoids the need to twist the wrist to perform pressure monitoring, and the pressing is also more stable, making it less likely for the ultrasound probe to shift during the pressing process.

[0049] However, in the existing technology, the probe has an angular shape, which can cause medical staff to hurt their fingers when using such a probe to press, and the operation often requires a twisted wrist posture, making it extremely uncomfortable to operate.

[0050] To further improve operational comfort and prevent the ultrasonic probe's housing 10 from bumping into hands or arms, such as... Figures 1 to 7 In some embodiments, the top edge of the housing body 10 may have a smooth transition with the side edge, i.e., the top edge of the housing body 10 is rounded. This prevents medical personnel from having their fingers pricked by the edge of the probe housing during use. The specific size of the rounded corner can be determined according to the overall size of the ultrasound probe, and is not limited here.

[0051] In one embodiment, primarily referring to Figure 5 and Figure 6 The shell body 10 may have a receiving cavity 10a for accommodating the ultrasonic transducer and a filling cavity 10b for filling the ultrasonic signal transmission medium. In this way, the convenience of assembling the ultrasonic heat exchanger and filling the ultrasonic signal transmission medium can be improved while minimizing the number of parts.

[0052] To facilitate assembly while maximizing the utilization of the internal space of the shell body 10, in one embodiment, referring to... Figures 1 to 7 The shell body 10 may include a first shell 110 and a second shell 120; the first shell 110 is located on the side away from the patient when the ultrasound probe is used, and the pinching part 11 is provided on two opposite sides of the first shell 110; the second shell 120 is connected to the first shell 110 and surrounds the first shell 110 to form a receiving cavity 10a and a filling cavity 10b.

[0053] In this embodiment, a partition 123 connecting the top and bottom of the second housing 120 is inclinedly disposed inside the second housing 120. The first housing 110, the first side plate 121 of the second housing 120, and the partition 123 form an accommodating cavity 10a; the second side plate 122 of the second housing 120 and the partition 123 form a filling cavity 10b. This further improves the utilization rate of the internal space of the housing body 10 and effectively ensures the accuracy of the ultrasonic transducer detection results.

[0054] In existing technologies, coupling agents are typically used as the medium for transmitting ultrasound signals. However, coupling agents are prone to drying out, and once they dry out, the fixed probe needs to be removed, refilled with coupling agent, and then fixed to the patient again, which is inconvenient.

[0055] In this regard, the present invention makes relevant improvements: In one embodiment, as follows Figures 5 to 7 As shown, the ultrasonic signal transmission medium filling the cavity 10b is a block coupling gel, and the shape of the block coupling gel is adapted to the shape of the cavity 10b.

[0056] It should be noted that when the ultrasound probe is fixed in the monitoring position, the gel is in contact with the patient's skin surface. The coupling gel, as a medium for transmitting ultrasound signals, can reduce the attenuation of the ultrasound signal. This invention, by placing a block-shaped coupling gel in the filling cavity 10b, prevents the gel from drying out easily during prolonged monitoring, thus avoiding frequent removal and replacement.

[0057] In addition, in one embodiment, the ultrasonic probe may also include a protective sleeve disposed on the top of the housing body 10, the shape of the protective sleeve being adapted to the shape of the housing body 10.

[0058] In this embodiment, the protective sleeve can be a silicone sleeve, which is used to accommodate the probe. The bottom shape of the silicone sleeve is adapted to the top shape of the probe, so that when the ultrasound probe is placed inside the silicone sleeve, the two can make close contact without gaps. This allows the probe to be moved without removing the silicone sleeve, but by pinching the silicone sleeve.

[0059] In summary, the ultrasound probe of this invention is more comfortable to use and easier to locate when pinching. When used on the wrist, the product's curvature allows medical personnel to press it comfortably. When used on the neck, the bottom filling cavity 10b can confine the gel, preventing it from shifting or falling out. By constructing a shape that conforms to the usage habits of medical personnel and adopting a curved surface that conforms to the shape of human fingers, the ultrasound probe of this invention achieves the technical effects of easy pinching, moving, and locating, making it more comfortable and convenient to use.

[0060] This invention also proposes an ultrasonic measuring device, which can be an ultrasonic blood flow monitoring device, a transcranial Doppler ultrasound device, etc., capable of monitoring the patient's blood flow status information, including blood flow velocity, volume changes, and other information. The ultrasonic measuring device includes an ultrasonic main unit and an ultrasonic probe electrically connected to the ultrasonic main unit. The specific structure of the ultrasonic probe is as described in the above embodiments. Since the ultrasonic measuring device proposed in this invention includes all solutions of all embodiments of the above-described ultrasonic probe, it at least has the same technical effects as the above-described ultrasonic probe, and will not be elaborated upon here.

[0061] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
