[0032] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0033] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. It should be understood that the terms "first", "second" and the like are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, the "first" information can also be referred to as "second" information, and similarly, the "second" information can also be referred to as "first" information.

[0034] As shown in Figures 1-8 The present application provides a nasal ultrasonic examination auxiliary device, which comprises a support plate 1 (made of hard material, such as composite plastic), as shown in Figure 8 A examination hole 11 is provided on the support plate 1, and a flexible sound guide 2 (with good acoustic performance, which can realize ultrasonic transmission) is located below the support plate 1. The upper end surface of the flexible sound guide 2 overlaps with the lower end surface of the support plate 1, and they are connected by adhesive. The vertical projection of the examination hole 11 is located within the vertical projection of the flexible sound guide 2. The flexible sound guide 2 outside the examination hole 11 is connected and fixed to the lower end surface of the support plate 1. The bottom of the flexible sound guide 2 is provided with a concave cavity 211 (for accommodating the nose) matched with the nose. According to the size of the nose of an adult or a child (of different ages), the flexible sound guide 2 with different sizes of concave cavities 211 is provided, so that the size of the concave cavity 211 is matched with the nose of the patient to be examined, and the flexible sound guide 2 is soft (can be stretched and shaped at will), so that the flexible sound guide 2 can be further matched with the surface of the nose of the patient to be examined.

[0035] In the embodiment, the upper surface of the flexible sound guide 2 can maintain a relatively flat surface under the pulling effect of the support plate 1. Without the pulling of the upper surface of the flexible sound guide 2 by the support plate 1, due to the softness of the flexible sound guide 2, when the flexible sound guide 2 is placed on the part to be examined (the nose), the upper surface of the flexible sound guide 2 is difficult to maintain a relatively flat surface, and when the ultrasonic probe is moved along the upper surface of the flexible sound guide 2 for examination, the ultrasonic probe is partially suspended, which causes the suspended area to be unable to be imaged on the display of the color Doppler ultrasound instrument, resulting in poor overall image quality.

[0036] In the embodiment, first, the medical staff lays the patient flat, then places the nasal ultrasonic examination auxiliary part on the patient's nose, and embeds the patient's nose into the concave cavity 211 at the bottom of the flexible sound guide 2, so that the flexible sound guide 2 wraps the nose and is attached to the surface of the nose. Then, the medical staff can move the ultrasonic probe on the upper surface of the flexible sound guide 2 in the examination hole 11, thereby completing the ultrasonic examination of the patient's nose. Because the upper surface of the flexible sound guide 2 is attached to the bottom wall of the support plate 1, under the pulling effect of the support plate 1, the upper surface of the flexible sound guide 2 can maintain a relatively flat surface. The flat contact surface allows the ultrasonic probe to rotate and move freely in the specified area (without the ultrasonic probe being partially suspended during movement), which facilitates the collection of ultrasonic images of the nose from multiple angles, improves the overall quality of the images, and enhances the work efficiency.

[0037] As shown in some embodiments of the present application, Figure 7 The nasal ultrasonic examination auxiliary part further includes a stopper 3 arranged around the edge of the support plate 1, and the stopper 3 is attached to the edge of the support plate 1. The stopper 3 protrudes upward from the upper end surface of the support plate 1, so that the inner side area of the stopper 3 forms a containing groove 31 for containing liquid sound guide medium. The liquid sound guide medium can be water, coupling agent, etc.

[0038] In the specific implementation of the embodiment, in order to further improve the ultrasonic imaging quality, a stopper 3 is arranged on the upper end face of the support plate 1 and surrounds the edge of the support plate 1, so that the stopper 3, the support plate 1 and the flexible sound guide 2 cooperatively form a containing groove 31. The containing groove 31 can be used to contain a certain amount of liquid sound guide medium. When the ultrasonic probe moves close to the upper surface of the flexible sound guide 2, the contact surface between the ultrasonic probe and the flexible sound guide 2 is always immersed in the liquid sound guide medium, so that the air at the contact position between the ultrasonic probe and the flexible sound guide 2 can be effectively removed (ultrasonic waves will rapidly attenuate in the air, so the application of the liquid sound guide medium between the probe and the flexible sound guide 2 can remove the air and enable the ultrasonic waves to smoothly enter the flexible sound guide 2), so that the imaging quality is further improved. At the same time, the liquid sound guide medium can also better reduce the friction between the ultrasonic probe and the upper surface of the flexible sound guide 2 during the movement of the ultrasonic probe on the upper surface of the flexible sound guide 2, facilitate the movement of the ultrasonic probe for scanning, and effectively avoid the wear of the ultrasonic probe and prolong the service life of the ultrasonic probe.

[0039] In some embodiments of the present application, the flexible sound guide 2 and the support plate 1 are detachably connected, which is helpful for subsequent cleaning and disinfection of the support plate 1 and the flexible sound guide 2. Since the support plate 1, the stopper 3 and the flexible sound guide 2 are made of different materials, the cleaning and disinfection processes used after use will also be different. The detachable flexible sound guide 2 is more conducive to subsequent cleaning and disinfection of the nasal ultrasonic examination auxiliary part in a more targeted and scientific manner. At the same time, the detachable connection of the flexible sound guide 2 and the support plate 1 facilitates separate storage of the support plate 1 and the flexible sound guide 2 according to different storage environment requirements, thereby improving the flexibility of the nasal ultrasonic examination auxiliary part.

[0040] In some embodiments of the present application, a detachable connection mode between the flexible sound guide 2 and the support plate 1 is provided, as follows:

[0041] As shown in Figure 2 The flexible sound guide 2 includes a main body part 21 and an extension part 22 protruding outward from the side wall of the main body part 21. The extension part 22 is provided with a plurality of extension parts 22, which are arranged at intervals around the outer periphery of the main body part 21. The upper end face of the extension part 22 is flush with the upper end face of the main body part 21. A clamping part that can move up and down is arranged on the lower end face of the support plate 1. The plurality of extension parts 22 are located between the clamping part and the support plate 1. The clamping part is moved upward to clamp the plurality of extension parts 22 at the bottom of the support plate 1. The clamping part is moved downward to release the clamping of the plurality of extension parts 22.

[0042] When the nasal ultrasound examination accessory needs to be installed on the bottom wall of the support plate 1, the clamping member is moved upward to clamp and position the extension 22 located between the clamping member and the bottom wall of the support plate 1, thereby fixing the main body 21 on the bottom wall of the support plate 1. When the main body 21 needs to be removed from the support plate 1, the clamping member is moved downward to release the clamping and positioning of the extension 22, and the flexible sound guide 2 can be removed from the support plate 1.

[0043] In some embodiments of this application, such as Figure 3 , Figure 4 As shown, the nasal ultrasound examination auxiliary component in this solution also includes a flexible membrane 4 laid in the receiving groove 31. The vertical projection of the receiving groove 31 is located inside the vertical projection of the flexible membrane 4. Since the flexible sound guide 2 is detachably connected to the bottom wall of the support plate 1, and the main body 21 is fixedly connected to the bottom wall of the support plate 1 by clamping the extension 22, a gap inevitably occurs between the upper surface of the main body 21 and the bottom wall of the support plate 1. To prevent leakage of the liquid sound guiding medium (water or coupling agent) in the receiving groove 31, a flexible membrane 4 (a disposable plastic film) is laid in the receiving groove 31. The flexible membrane 4 contacts the bottom wall of the receiving groove 31 (the bottom wall of the receiving groove 31 is composed of the upper surface of the flexible sound guide 2 and the upper end face of the support plate 1), and the edge of the flexible membrane 4 extends outside the receiving groove 31, such as... Figure 3 As shown, the liquid sound-conducting medium is positioned above the flexible membrane 4, effectively preventing leakage caused by gaps between the upper surface of the flexible sound-conducting component 2 and the bottom wall of the support plate 1. In this solution, the flexible membrane 4 can be discarded directly after inspection. In this embodiment, the flexible membrane 4 effectively prevents leakage of the liquid sound-conducting medium on the windward side, and also avoids direct contact between the flexible sound-conducting component 2, the support plate 1, the stop component 3, and the liquid sound-conducting medium, facilitating subsequent cleaning.

[0044] In some embodiments of this application, such as Figure 2 , Figure 5 As shown, the wall of the inspection hole 11 has an inclined surface 111 surrounding the inspection hole 11, which is arranged from bottom to top toward the stop member 3. The inclined surface 111 allows the flexible membrane 4 to extend along the inclined surface 111 from the upper surface of the flexible sound guide member 2 to the upper end surface of the support plate 1 when the flexible membrane 4 is laid, making the transition from the flexible membrane 4 to the support plate 1 smoother and preventing hollowness at the wall of the inspection hole 11.

[0046] As shown in some embodiments of the present application, Figure 1 As shown, the bottom of the guide rod 12 threadedly assembled with the guide hole 51 is provided with a screw handle 121, which helps the medical staff to rotate the guide rod 12 provided with threads and thereby control the up and down movement of the clamping frame 5; in order to avoid the screw handle 121 touching the human face, a layer of flexible rubber sleeve is also wrapped outside the screw handle 121, which plays a protective effect.

[0047] In some embodiments of the present application, the outer side edges of the clamping frame 5 and the stopper 3 are all provided with rounded corners, so as to prevent the nasal ultrasonic examination auxiliary device from being placed on the patient's face 6 and mistakenly contacting the patient's face 6, causing scratches on the patient's face 6, and ensuring safe use.
