Description

Technical Field

[0001] This invention relates to the field of medical electronic equipment technology, and specifically to a medical electronic equipment port and its port cover having an anti-loss, easy-to-operate magnetic structure. Background Technology

[0002] In the medical industry, the reliability, ease of use, and safety of equipment are directly related to patients' lives and health. Especially in environments such as hospitals, operating rooms, and treatment rooms, the port structure, as one of the core control components of medical equipment, not only needs to possess basic functionality but must also meet stringent hygiene and contamination prevention requirements. These devices are frequently exposed to high bacterial loads, high humidity, and frequent cleaning and disinfection operations. Any improper design can lead to equipment malfunction or bacterial growth, thereby affecting patient health and safety. The hygiene and contamination prevention design of push-button switches, input / output interfaces, and ventilation vents in medical equipment requires designers to consider multiple aspects, including material selection, structural design, waterproofing and dustproofing, and antibacterial disinfection, to ensure that push-button switches can operate stably and persistently in harsh medical environments.

[0003] Existing detachable port covers are prone to loss during high-frequency operation, exposing the ports to contaminated environments containing disinfectants, blood, etc., leading to equipment malfunctions or cross-infection. Traditional rotary / snap-on port covers require two-handed operation, delaying action in emergency rescue scenarios. Utility Model Content

[0005] The port base includes a groove, one or more first magnetic suction elements disposed in the groove, and one or more sockets disposed in the groove, wherein the sockets are for inserting corresponding connectors;

[0006] The port cover includes a cover body covering the groove and one or more second magnetic attractors disposed on the cover body. Each second magnetic attractor is opposite to and magnetically connected to the corresponding first magnetic attractor along a magnetic attraction direction perpendicular to the cover surface.

[0007] In some embodiments of this utility model, an anti-detachment unit is provided between the port cover and the port base to prevent them from completely separating.

[0008] In some embodiments of this utility model, the anti-detachment unit includes a flexible connector, one end of which is disposed on the port cover and the other end of which is disposed on the port base.

[0015] In some embodiments of this utility model, the flexible connector is made of elastic silicone or TPU material, and its length is configured to allow the port cover to be flipped up relative to the port base to the maximum opening angle, so that the socket is fully exposed.

[0016] In some embodiments of this utility model, the first magnetic suction member and the second magnetic suction member have T-shaped cross sections, including a large diameter end and a small diameter end. When the port cover is closed, the large diameter end of the first magnetic suction member and the small diameter end of the second magnetic suction member are arranged opposite to each other along the magnetic suction direction.

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Existing medical electronic equipment ports often use a separate port cover 2, and the port cover 2 and the port base 1 are connected by a snap-fit ​​structure. This not only makes it easy for the port cover 2 to be lost, but also requires two hands to open and close, and the sealing is not good, which can easily cause cross-infection.

[0027] Based on the aforementioned issues, please refer to Figures 1 and 2. This embodiment provides a port structure for medical electronic devices. The port structure includes a port base 1 disposed on the outer wall of the electronic device housing and a port cover 2 adapted to the port base 1. The port base 1 includes a groove 11, one or more first magnetic attractors 12 disposed in the groove 11, and one or more insertion ports 13 disposed in the groove 11. The insertion ports 13 are for inserting corresponding connectors. The port cover 2 includes a cover body 21 covering the groove 11 and one or more second magnetic attractors 22 disposed on the cover body 21. Each second magnetic attractor 22 is opposite to and magnetically connected to the corresponding first magnetic attractor 12 along a magnetic attraction direction perpendicular to the cover surface. Please refer to Figures 3 and 4. By providing the first magnetic attractor 12 in the groove 11 of the port base 1, and the first magnetic attractor 12 in the cover body 21 of the port cover 2, the first magnetic attractor 12 is provided in the groove 11 of the port base 1. A second magnetic clasp 22 is provided, and the two are magnetically connected along a magnetic direction perpendicular to the cover surface, enabling quick opening and closing of the port cover 2 and the port base 1. Compared to the traditional snap-fit ​​structure, the opening and closing action can be completed with one hand.

[0028] Furthermore, an anti-detachment unit is provided between the port cover 2 and the port base 1 to prevent complete separation between the two. This anti-detachment design ensures that the port cover 2 remains connected to the device at all times, significantly reducing maintenance costs and contamination risks due to loss. In some embodiments, the anti-detachment unit includes a flexible connector 4, with one end of the flexible connector 4 disposed on the port cover 2 and the other end disposed on the port base 1. This structure is simple and low-cost. The flexible connector 4 has a certain degree of flexibility, which neither affects the normal opening and closing angle of the port cover 2 nor fails to reliably prevent separation between the two.

[0029] In some specific examples, the anti-detachment unit includes a limiting hole 14 disposed in the groove 11 and a flexible connector 4 fixedly connected to the port cover 2; the flexible connector 4 has an extension section and a free end, the extension section extending from the cover 21 toward the limiting hole 14, and the free end forming a protrusion 41. The extension section is slidably inserted into the limiting hole 14, and the protrusion 41 is located on the side of the port base 1 away from the port cover 2, and is axially limited with the limiting hole 14. When the port cover 2 is subjected to a pulling force away from the port base 1, the axial limiting effect of the protrusion 41 and the limiting hole 14 can effectively prevent complete detachment, and the extension section of the flexible connector 4 can be slidably inserted into the limiting hole 14, allowing the port cover 2 to open to a sufficient angle to fully expose the socket 13 without affecting the insertion and removal operation of the connector. In addition, the protrusion 41 is located inside the port base 1, which does not occupy external space, making the appearance of the device simpler and avoiding damage to the limiting structure from external collisions, thus improving the durability of the structure.

[0030] The flexible connector 4 can take the form of, but is not limited to, silicone strips or connecting ropes. In this embodiment, the flexible connector 4 is a silicone strip, with the free end of the silicone strip forming a protrusion such as a mushroom head or a T-shaped block. The limiting hole 14 is a horizontally extending strip-shaped hole. Thus, when opened: the port cover 2 is lifted, the extension slides within the limiting hole 14, and the protrusion 41 moves accordingly but is limited by the strip-shaped hole; when the port cover 2 is excessively stretched, the protrusion 41 abuts against the inner wall of the limiting hole 14, preventing complete detachment.

[0031] In some embodiments of this utility model, the groove 11 and the cover 21 are provided with one or more mounting holes, the inner wall of the mounting hole forms a stepped surface, the first magnetic suction member 12 and the second magnetic suction member 22 are disposed in the mounting hole and form an axial stop with the stepped surface, which can effectively prevent the magnetic suction member from axially loosening or falling off during long-term magnetic attraction and opening and closing, and ensure the stability of the magnetic attraction connection.

[0032] In some embodiments of this utility model, the port cover 2 is a flexible component, and the first magnetic absorbing component 12 and the second magnetic absorbing component 22 are fixed in the groove 11 and the cover body 21 respectively by embedding, in-mold injection molding, or welding. For the port cover 2 made of flexible material, these fixing methods can form a tight bond with the flexible substrate: the embedding method can use the micro-elasticity of the flexible material to wrap the magnetic absorbing component and prevent loosening; in-mold injection molding can make the magnetic absorbing component integrated with the cover body 21 and the groove 11, eliminating gaps and reducing the risk of liquid and dust intrusion; welding, through molecular fusion between materials, makes the magnetic absorbing component firmly connected to the flexible substrate, and can maintain structural stability even under frequent opening and closing or disinfection and wiping operations, which not only meets the requirements of medical environment for equipment sealing and durability, but also does not affect the flexibility and magnetic attraction effect of the port cover 2. In addition, adhesive bonding can also be used.

[0033] Optionally, the flexible connector 4 is made of elastic silicone or TPU material, and its length is configured to allow the port cover 2 to be flipped up to the maximum opening angle relative to the port base 1, so that the socket 13 is fully exposed. Alternatively, the magnet can be modified in shape, not limited to a circle. In addition to a circle, a square magnet can also be used. During installation, a square magnet can better fit with a rectangular mounting hole, reducing shaking and improving the stability of the connection, making it suitable for scenarios with high installation accuracy requirements. An elliptical magnet has better guiding properties, enabling smoother alignment during the docking of the port cover 2 and the port base 1, making it particularly suitable for use in situations where space is limited or the operating angle is not ideal.

[0034] Furthermore, in this embodiment, the first magnetic attractor 12 and the second magnetic attractor 22 use the same type of magnet.

[0035] In some embodiments of this utility model, the first magnetic absorbing element 12 and the second magnetic absorbing element 22 have a T-shaped cross-section, including a large-diameter end and a small-diameter end. After the small end of the T-shape is embedded in the mounting hole of the flexible cover 21 / base 1, the large end forms a mechanical stop with the stepped surface. Combined with in-mold injection molding or adhesive bonding processes, the loosening of the magnetic absorbing element is completely prevented. When the port cover 2 is closed, the large-diameter end of the first magnetic absorbing element 12 and the small-diameter end of the second magnetic absorbing element 22 are positioned opposite each other along the magnetic attraction direction. By positioning the large-diameter end of the first magnetic absorbing element 12 and the small-diameter end of the second magnetic absorbing element 22 opposite each other, the magnetic attraction force is concentrated in the central area, forming a stronger magnetic attraction effect.

[0036] The large-diameter end of the first magnetic suction member 12 is positioned facing the inside of the equipment housing, and the large-diameter end of the second magnetic suction member 22 is positioned facing the outside of the cover 21. The large end faces the non-exposed side, which reduces the direct contact of disinfectant with the magnetic seam and reduces the risk of corrosion.

[0037] For example, the port base 1 provided here has two data ports 13, and two mounting slots are formed on the side of the port base 1 away from the cover 21 for mounting circuit boards.

[0038] It is understood that the port structure mentioned in any of the foregoing embodiments can be used in existing medical electronic devices.
