Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a medical ultrasound probe device with a protective structure. Background Technology

[0002] Ultrasound probes are widely used in the medical field. They use ultrasound waves to detect lesions and generate images, thereby helping doctors to determine the pathology of the lesions.

[0003] Existing devices typically have a crystal that allows ultrasound to pass through on the detection end face, but they lack protection for the crystal. When the device falls from a height, because the detection end of the device is large and heavy, the detection end face will fall towards the ground. Therefore, the detection end will impact the ground first, causing the crystal fixed on the detection end face to shatter. Summary of the Invention

[0004] The purpose of this invention is to provide a medical ultrasound probe device with a protective structure to solve the technical problem of the lack of protection for crystals in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medical ultrasound probe device with a protective structure, comprising:

[0007] A flow guide channel, wherein the air inlet of the flow guide channel is located on the detection end face, the flow guide channel includes an air inlet section, an acceleration section and an air outlet section, the acceleration section is a gradually narrowing flow channel, and the cross-sectional area of ​​the flow channel decreases from the air inlet section to the air outlet section;

[0008] The compression chamber is connected to the outlet of the guide channel. External airflow enters the guide channel and is accelerated by the acceleration section to guide the gas into the compression chamber, so as to regulate the compression of the gas pressure inside the compression chamber.

[0009] A dynamic deformation shield, which is arranged in a ring coaxially on the detection end face of the body, the dynamic deformation shield includes:

[0010] A protective plate, which is hinged in a scale-like shape on the detection end face, the protective plate includes a hinged end and a movable end;

[0011] An airbag is embedded between the probe end face and the protective plate, and is connected to the compression chamber;

[0012] The dynamically deformable shield is configured as follows:

[0013] Under normal conditions, the protective plate is fitted snugly against the detector end face;

[0014] When the main body falls, the probe is facing downwards, and high-pressure gas is injected into the airbag to inflate and deform the airbag.

[0015] The airbag pushes the protective plate to rotate and tilt around the hinge end until the movable end is higher than the crystal horizontal plane, so that the dynamic deformation shield topology unfolds so that the protective area covers the crystal area.

[0016] Preferably, a guide sleeve and a rotatable compression sleeve are coaxially nested within the body. The guide channel is located between the guide sleeve and the compression sleeve. Centrifugal blades are evenly distributed circumferentially on the outer wall of the compression sleeve at the air inlet section, and rotor blades are evenly distributed circumferentially on the outer wall of the compression sleeve at the air outlet section.

[0017] Preferably, the inner wall of the guide sleeve is circumferentially distributed with stator blades, and the stator blades and rotor blades are arranged axially in an alternating manner to compress the airflow entering the guide channel step by step.

[0018] Preferably, the airbag is filled with aerogel.

[0019] Preferably, the airbag includes a fixed end and a folded end, the folded end is connected to the movable end of the protective plate, and a spring is provided inside the airbag along the extension direction of the folded end.

[0020] Preferably, the impact surface of the protective plate is provided with multiple rubber pads arranged with gaps, and the rubber pads are arranged in a hexagonal honeycomb pattern.

[0021] Preferably, the rubber pads are arranged in a herringbone pattern from the movable end to the hinge end, and the height of each layer gradually increases.

[0022] Preferably, the protective plate is provided with a movable shaft.

[0023] Preferably, the detection end face of the body is embedded with a protective seat arranged in a ring shape, the dynamic deformation shield is set on the protective seat, and the protective seat is circumferentially distributed with rubber blocks and pressure limiting cavities.

[0024] Preferably, the rubber block has a deformation cavity that communicates with the pressure limiting cavity, and the movable shaft is inserted into the rubber block, with the end of the movable shaft away from the protective plate corresponding to the position of the deformation cavity.

[0025] In the above technical solution, the medical ultrasound probe device with a protective structure provided by the present invention has the following beneficial effects:

[0026] This invention, through the design of an airbag, a guide channel, and a protective plate, allows the device to be dropped from a height with its detection end facing downwards. During the drop, airflow enters the intake section through the air inlet of the guide channel located on the detection end face of the main body. From the intake section, the airflow enters the acceleration section, where it is accelerated before flowing into the exhaust section. The accelerated airflow then enters the compression chamber through the exhaust section. As airflow continuously enters the compression chamber, the air pressure inside increases. This pressure, through a connecting pipe between the compression chamber and the airbag, compresses the gas into the airbag, causing it to inflate and expand, thus allowing the gas to pass through. The capsule drives the protective plate to rotate and tilt around the hinge end until the movable end is higher than the crystal's horizontal plane, thereby causing the dynamic deformation shield to unfold topologically. This provides multi-angle protection for the crystal, physically isolating it from the impact load. The pneumatic trigger achieves millisecond-level response during the fall. Through the topological unfolding of the dynamic deformation shield, a full-time-domain protective field is constructed in the crystal area, dissipating the impact energy in real time to non-sensitive areas, thereby reducing the surface stress of the crystal and achieving zero-contact protection throughout the fall. This effectively prevents the probe head from pointing downwards during the fall, which could cause the crystal to shatter upon impact with the ground. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-8 As shown, a medical ultrasound probe device with a protective structure includes:

[0040] Body 1, with a crystal 2 disposed on its detection end face;

[0041] The flow guide channel has its inlet end located on the detection end face. The flow guide channel includes an inlet section, an acceleration section, and an outlet section. The acceleration section is a gradually narrowing flow channel with a cross-sectional area decreasing from the inlet section to the outlet section.

[0042] Compression chamber 5 is connected to the air outlet of the guide channel. External airflow enters the guide channel and is accelerated by the acceleration section to guide the gas into compression chamber 5, so as to regulate the internal air pressure compression of compression chamber 5.

[0043] A dynamic deformation shield, which is arranged in a ring and coaxially on the detection end face of the main body 1, includes:

[0044] The protective plate 3 is hinged in a scale-like shape on the detection end face. The protective plate 3 includes a hinged end and a movable end.

[0045] Airbag 8 is embedded between the detection end face and the protective plate 3, and is connected to the compression chamber 5;

[0046] The dynamic deformation shield is configured as follows:

[0047] Under normal conditions, the protective plate 3 is fitted to the probe end face;

[0048] When the main body 1 falls, the probe end faces downwards, and high-pressure gas is injected into the airbag 8 to inflate and deform the airbag 8.

[0049] The airbag 8 pushes the protective plate 3 to rotate and tilt around the hinge end until the movable end is higher than the horizontal plane of the crystal 2, so that the dynamic deformation shield topology unfolds so that the protective area covers the area of ​​the crystal 2.

[0050] Specifically, when the device falls from a height, because the detector end of the device is large in size and heavy in weight, the detector end will fall towards the ground. Therefore, the detector end will hit the ground first, causing the crystal 2 fixed on the detector end to shatter. Therefore, a dynamic deformation shield is set up to establish a full-time protection field to protect the crystal 2 in real time.

[0051] Furthermore, when the device falls from a height, with its detection end facing downwards, the airflow enters the intake section through the air inlet of the guide channel located on the detection end face of the main body 1, and then enters the acceleration section. Since the acceleration section is a gradually narrowing flow channel, the cross-sectional area of ​​the flow channel decreases from the intake section to the outlet section, following the principle that the flow velocity is small where the cross-section is large and large where the cross-section is small. After the airflow is accelerated in the acceleration section, it flows into the outlet section, thereby achieving efficient airflow acceleration and directional energy conversion, effectively shortening the protection response time and achieving timely protection.

[0052] Furthermore, the accelerated airflow enters the compression chamber 5 through the outlet section. As the airflow continuously enters the compression chamber 5, the air pressure inside the compression chamber 5 increases. This, through the connecting pipe 6 between the compression chamber 5 and the airbag 8, compresses the gas into the airbag 8, causing the airbag 8 to inflate and expand. The airbag 8 then drives the protective plate 3 to rotate and tilt around the hinge end until the movable end is above the horizontal plane of the crystal 2. This causes the dynamic deformation shield to deploy topologically, providing multi-angle protection for the crystal 2 and physically isolating the crystal 2 from the impact load. The millisecond-level response during the fall is achieved through pneumatic triggering. The deployment of the dynamic deformation shield topologically constructs a full-time-domain protection field for the crystal 2 area, dissipating the impact energy in real time to non-sensitive areas. This reduces the surface stress of the crystal 2, achieving zero-contact protection throughout the fall and effectively preventing the probe head from pointing downwards during the fall, which could cause the crystal 2 to shatter upon impact with the ground.

[0053] As a further embodiment of the present invention, a guide sleeve 7 and a rotatable compression sleeve 4 are coaxially nested inside the main body 1. The guide channel is located between the guide sleeve 7 and the compression sleeve 4. Centrifugal blades 14 are evenly distributed circumferentially on the outer wall of the compression sleeve 4 at the air inlet section and rotor blades 12 are evenly distributed circumferentially on the outer wall of the compression sleeve 4 at the air outlet section.

[0054] Specifically, when the device falls from a height, its detection end faces downwards. During the process, the airflow enters the inlet section through the air inlet of the guide channel located on the detection end face of the main body 1, and then enters the acceleration section. Since the acceleration section is a gradually narrowing flow channel, the cross-sectional area of ​​the flow channel decreases from the inlet section to the outlet section, following the principle that the flow velocity is lower where the cross-section is larger and higher where the cross-section is smaller. After being accelerated in the acceleration section, the airflow flows into the outlet section. The airflow enters the guide channel between the guide sleeve 7 and the compression sleeve 4, and flows towards the circumferentially distributed centrifugal blades 14 on the outer wall of the compression sleeve 4, thereby carrying... The dynamic compression sleeve 4 rotates and is mounted on the outer wall of the inner core of the main body 1. Under the push of the centrifugal blades 14, the gas flows along the surface of the centrifugal blades 14 toward the acceleration section, thereby generating a vortex in the airflow under the action of the centrifugal blades 14 and generating a negative pressure in the center region of the vortex of the centrifugal blades 14, thereby drawing in external air and ensuring that enough gas enters to compress the air pressure in the compression chamber 5, so that the airbag 8 can inflate smoothly and quickly, thereby ensuring that the dynamic deformation shield can deploy in time to protect the crystal 2 when the device falls.

[0055] As a further embodiment of the present invention, stator blades 13 are evenly distributed circumferentially on the inner wall of the guide sleeve 7. The stator blades 13 and rotor blades 12 are arranged axially in an alternating manner to compress the airflow entering the guide channel step by step.

[0056] Specifically, the airflow enters the guide channel between the guide sleeve 7 and the compression sleeve 4, and flows to the centrifugal blades 14 evenly distributed circumferentially on the outer wall of the compression sleeve 4, thereby driving the compression sleeve 4 to rotate. The rotation of the compression sleeve 4 causes the rotor blades 12 evenly distributed circumferentially on the outer wall of the compression sleeve 4 located at the outlet section to rotate synchronously. When the airflow passes through the acceleration section and flows into the outlet section, because the stator blades 13 are evenly distributed circumferentially on the inner wall of the guide sleeve 7, and the stator blades 13 and the rotor blades 12 are axially staggered, a multi-stage compression chamber is formed. When the airflow passes through, it undergoes a cycle of acceleration-diffusion-re-acceleration, which increases the gas pressure step by step, thereby improving the gas compression efficiency and further reducing the response time of the airbag 8, thus achieving timely protection response.

[0057] Furthermore, the stator blades 13 and rotor blades 12 are arranged in an alternating manner to disrupt axial symmetry, suppress the generation of large-scale vortices, and enable the airflow to form a stable laminar flow in the compression chamber 5. This ensures that the gas is smoothly injected into the airbag 8, making the airflow compression process continuous and uninterrupted, and ensuring the stable and rapid operation of the triggering system.

[0058] As a further embodiment of the present invention, the airbag 8 is filled with aerogel.

[0059] Specifically, by filling the airbag 8 with aerogel, the nanoscale three-dimensional network structure of the aerogel absorbs impact energy through a triple mechanism of pore collapse, skeleton buckling, and interface friction. The aerogel exhibits significant hardening characteristics under high-speed impact, achieving adaptive stiffness adjustment: for low-energy collisions, flexible deformation absorbs energy, while for high-energy impacts, rigid resistance prevents bottoming out. Thus, when the device falls, after the airbag 8 inflates, the protective plate 3 impacts the ground, and the airbag 8 at the corresponding position receives a high-energy impact. The internal aerogel hardens, preventing bottoming out while effectively reducing the impact force on the crystal 2 area, further improving the protection effect on the crystal 2.

[0060] As a further embodiment of the present invention, the airbag 8 includes a fixed end and a folding end, the folding end is connected to the movable end of the protective plate 3, and a spring is provided inside the airbag 8 along the extension direction of the folding end.

[0061] Specifically, the airbag 8 inflates and deforms, and the folded end extends, thereby driving the movable end of the protective plate 3 to rotate and unfold to protect the crystal 2. Through the spring, it is stretched when the dynamic deformation shield unfolds. As the spring needs to restore its elastic deformation, it gradually pulls the protective plate 3 to automatically reset.

[0062] As a further embodiment of the present invention, the impact surface of the protective plate 3 is provided with a plurality of rubber pads 16 arranged with gaps, and the rubber pads 16 are arranged in a hexagonal honeycomb pattern.

[0063] Specifically, the hexagonal honeycomb structure of the rubber pad 16 absorbs impact energy, thereby further reducing the impact force in the crystal 2 region.

[0064] As a further embodiment of the present invention, the rubber pad 16 is arranged in a herringbone layer from the movable end to the hinge end, and the height of each layer gradually increases.

[0065] Specifically, the 16 layers of rubber pads are arranged in a herringbone pattern to form a multi-directional force transmission path, which disperses the impact energy along the longitudinal direction of the protective plate 3, avoids stress concentration, and thus effectively improves the protective performance of the protective plate 3.

[0066] Specifically, because the height of each layer of rubber pad 16 gradually increases from the moving end to the hinge end, a three-level buffer response is formed:

[0067] Primary buffer (lower layer): absorbs high-frequency, low-energy impacts;

[0068] Secondary buffer (middle layer): dissipates mid-frequency energy;

[0069] Level 3 buffer (high-level pad): resists low-frequency high-energy impacts, prolongs the impact time through large deformation, thereby further improving the buffering capacity of the protective plate 3 and the protective effect on the crystal 2.

[0070] As a further embodiment of the present invention, a movable shaft 15 is provided on the protective plate 3.

[0071] As a further embodiment of the present invention, the detection end face of the body 1 is embedded with a protective seat 9 arranged in a ring shape, a dynamic deformation shield is arranged on the protective seat 9, and rubber blocks 10 and pressure limiting cavities 11 are evenly distributed in the circumference inside the protective seat 9.

[0072] As a further embodiment of the present invention, a deformation cavity 101 communicating with the pressure limiting cavity 11 is provided in the rubber block 10, and a movable shaft 15 is inserted into the rubber block 10, with the end of the movable shaft 15 away from the protective plate 3 corresponding to the position of the deformation cavity 101.

[0073] Specifically, the protective plate 3 is inserted into the rubber block 10 via a movable shaft 15. When the dynamic deformation shield is deployed, the protective plate 3 rotates, thereby driving the movable shaft 15 to rotate within the rubber block 10 and compress the corresponding deformation cavity 101 within the rubber block 10 to contract and deform, thus realizing the rotation and deployment of the protective plate 3. At the same time, the contraction and deformation of the deformation cavity 101 compresses the air pressure within the deformation cavity 101 into the pressure limiting cavity 11, thereby forming air pressure resistance, thus preventing the protective plate 3 from rotating excessively and ensuring that the rotation angle of the protective plate 3 is within the effective protection range.

[0074] Furthermore, the rubber blocks 10 evenly distributed in the inner circumference of the protective seat 9 form a continuous pressure ring, and the impact energy is evenly dispersed through the shear coupling between the rubber blocks 10, thereby improving the uniformity of stress distribution in the crystal 2 region.

[0075] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
