Description

Technical Field

[0001] This utility model relates to the field of medical and sanitary materials and dressings, and in particular to an intracavitary ultrasound probe isolation membrane device. Background Technology

[0002] Traditional intracavitary ultrasound probe diaphragms have the following drawbacks: 1. Structural defects: The single-layer latex membrane lacks support at the connection point with the probe handle, making it prone to slippage and causing displacement or detachment of the diaphragm during operation. 2. Operational defects: The installation process is cumbersome and time-consuming, affecting medical efficiency. Existing improved technologies, such as plastic support rings or ribbon binding methods, attempt to solve these problems, but issues such as insecure fixation and awkward operation still exist, failing to meet clinical needs. Therefore, improvements are necessary. Utility Model Content

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] It is readily understood that, based on the technical solution of this utility model, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meanings of the above-mentioned components within this utility model according to the specific circumstances.

[0027] In some embodiments of this utility model, the following are included: a front-end isolation membrane 1 for wrapping the working part of the probe 5; a rear-end deformable metal membrane 4 connected to the front-end isolation membrane 1 for covering the handle of the probe 5; a connecting structure 2 for fixing the front-end isolation membrane 1 and the rear-end deformable metal membrane 4 together; and a telescopic extension structure provided at one end of the rear-end deformable metal membrane 4 near the handle of the probe 5.

[0028] Specifically, the front-end isolation membrane 1 uses a cylindrical structure to directly wrap the detection working part of the probe 5, and its opening is seamlessly connected to the rear-end deformable metal membrane 4 through the connecting structure 2. The rear-end deformable metal membrane 4 covers the outer periphery of the probe 5 handle, and its end integrates a telescopic extension structure. The connecting structure 2 typically uses a ring-shaped medical strong adhesive tape or heat sealing process to ensure the sealing and mechanical strength of the front and rear connection. The telescopic extension structure is located in the area where the rear-end deformable metal membrane 4 contacts the probe 5 handle, and uses a telescopic design to adjust the fit.

[0029] The front-end isolation membrane 1 is preferably made of latex, with a thickness controlled between 0.1-0.3mm to ensure sufficient elasticity without affecting the transmission of ultrasound signals. Polyurethane or silicone can also be used to meet specific sterilization requirements. Its structure is a closed-end cylindrical shape, with an open rear end connected to the rear deformable metal membrane 4 via heat sealing or adhesive bonding. The rear deformable metal membrane 4 employs a multi-layer composite structure: the outer layer is 0.4-0.6mm thick medical-grade aluminum foil, providing good deformation performance; the middle layer can be spirally wound galvanized iron wire 3 (0.7-0.9mm in diameter) or woven metal mesh as a reinforcing skeleton. The connecting structure 2 preferably uses medical-grade pressure-sensitive tape, employing a spiral winding method to achieve a firm connection between the front and rear ends. Heat sealing can also be used to fuse the front and rear materials together. Specific implementation methods for the telescopic and extendable structure include: a corrugated tube design using medical-grade stainless steel or aluminum; a spiral spring design using elastic metal wire; and a folding accordion design, similar to the pleated structure of an accordion. These designs can achieve both axial expansion and contraction and radial stiffness retention.

[0030] Working principle: During installation, medical personnel insert the working part of probe 5 into the front isolation membrane 1, which automatically wraps around probe 5 due to its own elasticity. Then, the telescopic structure of the rear deformable metal membrane 4 is stretched to cover the handle of probe 5. By moderately squeezing the rear deformable metal membrane 4, the plastic deformation characteristics of aluminum foil and the elastic restoring force of the wire skeleton 3 are used to achieve a tight surface fit with the handle.

[0031] In some embodiments of this invention, the connecting structure 2 is a medical-grade strong adhesive tape. Specifically, the medical-grade strong adhesive tape achieves a full-circumference seal through circular wrapping, completely isolating the gap between the front-end isolation membrane 1 and the rear-end deformable metal membrane 4, preventing contaminants from entering the probe 5. Compared to traditional heat sealing processes or ordinary adhesives, the medical-grade strong adhesive tape does not release harmful substances, ensuring the aseptic requirements of interventional procedures. The tape allows for rapid application and slight positional adjustments (e.g., if the initial application is not perfect, it can be peeled off and reapplied), significantly improving intraoperative efficiency. Compared to heat sealing processes that require specialized equipment, or mechanical clips that require precise alignment, the tape is more suitable for emergency use in operating rooms. The tape can adapt to the connection of films made of different materials (e.g., latex and aluminum foil, polyurethane and metal mesh), and its flexibility can compensate for the deformation differences of different materials, avoiding tearing caused by stress concentration at the connection. Traditional rigid connections (e.g., plastic retainers) are prone to loosening after repeated stretching and contraction, while the elastic adhesive layer of the tape can deform synchronously with the stretching and contraction structure. Medical tape is for single use only and requires no maintenance, avoiding the cleaning and disinfection issues associated with complex connection structures (such as metal clips that may retain stains).

[0032] In some embodiments of this invention, the deformable metal film 4 at the rear end is an aluminum foil layer with a thickness of 0.4-0.6 mm. The 0.4-0.6 mm thick aluminum foil possesses ideal plastic deformation capability, enabling it to tightly conform to the surface of the handle of probes 5 of different diameters. This thickness range of aluminum foil maintains sufficient rigidity while allowing for manual shaping by hand, achieving a surface-to-surface fit with the handle. Medical-grade aluminum foil has a smooth surface, is not prone to contaminant adhesion, and its thickness is moderately costly, making it suitable for single-use.

[0033] In some embodiments of this utility model, the telescopic extension structure is a corrugated folding structure. The corrugated folding structure can flexibly adjust its length by unfolding or compressing, which can adapt to the length requirements of 5 handles for probes of different specifications. The stretching or compression operation can be completed with one hand without the need for other tools or complicated steps. The corrugated material has high fatigue strength, is not easy to break, and has a service life far exceeding that of traditional fixing methods. The corrugated surface is smooth, easy to clean and disinfect, and the dead-angle-free structural design avoids the accumulation of contaminants.

[0034] In some embodiments of this invention, the contact length between the deformable metal film 4 at the rear end and the handle of the probe 5 is 50-100mm. The 50-100mm contact length conforms to the ergonomic grip range (suitable for the width of an adult's palm), and the 50-100mm contact area provides sufficient operational feedback, avoiding the cumbersome feeling caused by being too long or the unstable grip caused by being too short.

[0035] In some embodiments of this invention, the front-end isolation membrane 1 is made of latex. Latex material has excellent elastic recovery, allowing it to tightly conform to the working parts of probes 5 of different diameters, forming a gapless seal and effectively preventing the penetration of body fluids and contaminants. Latex material has ideal acoustic permeability, and its acoustic impedance is close to that of human tissue, ensuring that image quality is not affected. Its low coefficient of friction facilitates probe 5 insertion, and its excellent tear resistance allows it to withstand the mechanical stress of intracavitary operation.

[0036] In some embodiments of this invention, the surface of the deformable metal layer at the rear end is wound with an iron wire 3. The diameter of the iron wire 3 is 0.7-0.9 mm, and the pitch is 3-5 mm. The spirally wound iron wire 3 skeleton provides radial stiffness, the 0.7-0.9 mm diameter iron wire 3 provides sufficient support while maintaining flexibility, and the 3-5 mm pitch design ensures that the aluminum foil layer can achieve 30-50% compressive deformation. This parameter range allows doctors to easily shape it with a single hand grip. The spiral structure allows the deformable metal film 4 at the rear end to shrink uniformly along the circumference of the probe 5 handle, and there is no elastic rebound after it is gripped and fixed.

[0037] In some embodiments of this invention, the extension length of the telescopic structure is 300-500mm. Specifically, the minimum extension length of 300mm ensures the operational requirements of covering the standard probe's five handles (typically 200-250mm). The maximum extension length of 500mm adapts to the needs of extended types and special cavity exploration, perfectly matching the anatomical dimensions of human cavities (such as different application scenarios like rectoscopes and colposcopes).

[0038] This invention achieves surface adhesion by designing a deformable metal film 4 at the rear end to cover the probe 5 and handle, thus preventing slippage; the telescopic extension structure flexibly controls the contact area with the handle by adjusting the extension length, thus avoiding slippage caused by size mismatch.

[0039] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
