Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and more specifically, it relates to an ultrasound probe sound-conducting cap device. Background Technology

[0002] Ultrasound diagnosis is a diagnostic method that applies ultrasound technology to the human body to measure and understand physiological or tissue structure data and morphology, thereby detecting diseases and providing diagnostic suggestions. Although my country's ultrasound medical imaging equipment industry started relatively late, after years of development, it has formed a complete industrial system with comprehensive professional categories and solid basic technologies.

[0003] However, existing ultrasound detection technologies still have some drawbacks, such as poor coupling between the ultrasound probe and the skin, leading to limited detection range and low image quality. Therefore, a novel ultrasound cap is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a sound-conducting cap device for ultrasound probes.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ultrasonic probe sound-conducting cap device, including a probe cap, a wrapping layer at the bottom of the probe cap, a fixing member at the bottom of the wrapping layer, and a sound-conducting layer inside the probe cap.

[0006] By adopting the above technical solution, the probe cap and wrapping layer are made of elastic material, which can fit the ultrasonic probe well. The fastener is used to fix the ultrasonic probe wiring terminal, and the sound guiding layer can fully cover the top surface of the ultrasonic probe, thereby improving the detection range.

[0007] The present invention is further configured such that a thin film is provided on the top of the probe cap.

[0008] By adopting the above technical solution, the cap top is made of a thin film to minimize the impact of the probe cap on the ultrasonic probe detection.

[0009] The present invention is further configured such that the sound guiding layer is a semi-solid sound guiding layer.

[0010] By adopting the above technical solution, a semi-solid sound-conducting layer made of PDMS (polydimethylsiloxane) is used. This material can maintain its elasticity for a long time in the temperature range of -65 to 200℃. It has excellent electrical and chemical stability. After the ultrasonic probe is installed, it can fit the ultrasonic probe well, ensuring full coverage of the ultrasonic probe detection layer and improving its detection effect.

[0011] The present invention is further configured such that: exhaust micro-holes are provided on both sides of the probe cap.

[0012] By adopting the above technical solution, the exhaust micropores are used to discharge excess gas and semi-solid sound guiding layer when the inner layer of the sound guiding cap is docked and coupled with the surface layer of the probe and the test object.

[0013] The present invention is further configured such that the probe cap is aligned with the wrapping layer.

[0014] By adopting the above technical solution, the probe cap is separated from the wrapping layer. Each time the probe cap and wrapping layer are installed, the probe cap and wrapping layer need to be connected.

[0015] In summary, this utility model has the following beneficial effects:

[0016] Optimized acoustic conduction performance and improved patient experience: The semi-solid acoustic conduction layer (PDMS) in the ultrasound probe cap can be uniformly attached to the probe surface under pressure. Combined with the thin film, it optimizes the coupling effect between the ultrasound probe and the skin, improves acoustic conduction performance, and thus improves imaging quality; it achieves a very good coupling effect without the need to apply a large amount of coupling agent to the patient's examination site.

[0017] It is easy to operate. The wrapping layer and fixing parts do not need to be replaced frequently. Each time you use it, you only need to replace one probe cap and align its bottom with the top of the wrapping layer. The operation is very simple.

[0018] Hygiene and patient experience are guaranteed: A new ultrasound cap is replaced after each ultrasound examination to ensure hygiene and prevent cross-infection. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will be described in detail below with reference to the embodiments.

[0025] Example:

[0026] like Figures 1-3 As shown, an ultrasound probe sound-conducting cap device includes a probe cap 1, a wrapping layer 2 at the bottom of the probe cap 1, a fixing member 3 at the bottom of the wrapping layer 2, and a sound-conducting layer inside the probe cap 1.

[0027] In this embodiment, the surrounding parts, such as the probe cap 1, the wrapping layer 2, and the fixing member 3, are made of transparent silicone. When in use, medical personnel first put the wrapping layer 2 on the handle of the ultrasound probe, fix the ultrasound probe terminal with the fixing member 3, and then put the probe cap 1 on the top of the probe. The probe detection point is close to the inner sound guiding layer of the probe cap 1 to optimize the sound guiding performance.

[0028] The top of the probe cap 1 is provided with a thin film 101.

[0029] In this embodiment, during use, the probe cap 1 has an elastic sound-conducting layer inside. When the probe cap 1 is installed on the ultrasound probe, the sound-conducting layer undergoes elastic deformation during the installation and compression process, tightly adhering to the probe surface. Combined with the thin film on top of the sound-conducting layer, the coupling effect between the existing ultrasound probe and the skin can be optimized, thus improving the detection effect and improving the imaging quality.

[0030] The sound guiding layer adopts a semi-solid sound guiding layer 4.

[0031] In this embodiment, the present invention uses polydimethylsiloxane (PDMS) as a coupling agent (semi-solid acoustic guiding layer 4). PDMS has a very good dielectric constant, which is beneficial for ultrasonic wave transmission. At the same time, PDMS has extremely high transparency and excellent softness and biocompatibility, making it very suitable as a coupling agent for ultrasonic detection that comes into contact with the skin.

[0032] PDMS (polydimethylsiloxane) is a two-component kit consisting of liquid components A and B, including PDMS and a curing agent. The PDMS basic component and curing agent are completely mixed at a weight ratio of 10:1, resulting in a medium-viscosity mixture similar in consistency to SAE 40 silicone oil. After mixing and heating (recommended between 80℃ and 120℃), regardless of thickness, the mixture will cure into a tough, transparent elastomer that maintains its elasticity over a long period within a temperature range of -65℃ to 200℃. It possesses excellent electrical and chemical stability. It is water-resistant, ozone-resistant, weather-resistant, moisture-proof, shock-proof, non-corrosive, physiologically inert, non-toxic, odorless, easy to pour, capable of deep vulcanization, has low linear shrinkage, and is simple to operate. No byproducts are produced during the reaction. It can be applied to surfaces of materials such as PC (polycarbonate), PP, ABS, PVC, and metals. It allows for natural defoaming.

[0033] The probe cap 1 has exhaust micro-holes 102 on both sides.

[0034] In this embodiment, the semi-solid sound-conducting layer 4 is an integral part of the sound-conducting cap 1 and is manufactured during the production process, so it does not need to be installed when in use. When the sound-conducting cap 1 is installed on the ultrasonic probe, the semi-solid sound-conducting layer 4 will be compressed to a certain extent. The exhaust micropores 102 can discharge excess gas and the semi-solid sound-conducting layer 4, so that the probe can be seamlessly connected to the surface of the subject with a complex shape.

[0035] The probe cap 1 is docked with the wrapping layer 2.

[0036] In this embodiment, the probe cap 1 is separated from the wrapping layer 2. Each time the probe cap 1 and the wrapping layer 2 are installed, the probe cap 1 and the wrapping layer 2 need to be connected. Once connected, the installation is successful. At this time, the semi-solid sound guiding layer 4 is evenly spread on the probe under the action of pressure.

[0037] Working principle:

[0038] When using the ultrasound probe, after assembling the wrapping layer 2 and the fixing piece 3 in advance, medical personnel should observe whether the semi-solid sound-conducting layer 4 inside the probe cap 1 is intact. After confirming that it is intact, the probe cap 1 is placed on top of the ultrasound probe. The probe cap 1 should be aligned with the wrapping layer 2, and the gap between the two can be ignored. This indicates that the installation is complete. At this time, the semi-solid sound-conducting layer inside the probe cap 1 is in full contact with the surface of the ultrasound probe. During this process, the exhaust micropores 102 can discharge excess gas and the semi-solid sound-conducting layer 4. This is a single-use procedure. After each ultrasound examination, a new sound-conducting cap 1 can be replaced according to the above procedure to ensure hygiene during each use. The used sound-conducting cap 1 can be recycled and returned to the factory for disinfection and the production of a new sound-conducting cap 1 for reuse, ensuring hygiene while avoiding resource waste.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
