Description

Technical Field

[0001] This utility model relates to the field of medical disinfection equipment technology, and in particular to a disinfection cabinet. Background Technology

[0002] A TEE (Transesophageal Echocardiography) probe is a medical device specifically designed for examining the structures of the heart and major blood vessels. During use, the insertion of the TEE probe into the esophagus is similar to that of an electronic gastroscopy. After the probe is safely inserted into the esophagus, its depth within the esophagus is adjusted by advancing, retreating, rotating, and bending forward, backward, left, and right, allowing for the examination of the heart and major blood vessel structures from superficial to deep.

[0003] TEE probes are high-precision instruments and are expensive. The main components of a TEE probe include a transducer at the tip, a flexible tube, and a handle. TEE probes are sterilized in a dedicated sterilizer to ensure reusability and prevent cross-infection when different patients use the same probe. Common sterilizers use ultraviolet (UV) light. During sterilization, the TEE probe is placed in the sterilization chamber, the cabinet door is closed, the chamber is sealed, and the UV light illuminates to sterilize the probe.

[0004] Because the transducer at the probe tip and the flexible tube extend into the patient's esophagus during use, their sterilization requirements are high, while the handle, which does not normally come into contact with the patient, has lower sterilization requirements. However, existing sterilization cabinets have uniform light intensity throughout the sterilization chamber, requiring a minimum light intensity to meet the sterilization requirements of the transducer at the probe tip and the flexible tube. This exposes the handle to excessively high-intensity ultraviolet radiation, wasting energy and converting it into heat, thus affecting the lifespan of the sterilization cabinet.

[0037] Please see Figures 1 to 4This utility model proposes a disinfection cabinet 100 for disinfection of medical ultrasound probes, including a cabinet body 11, a cabinet door 12, a primary disinfection module 13, and a secondary disinfection module 14. The cabinet body 11 has a receiving groove 111 on one side. The cabinet door 12 is movably installed on the cabinet body 11 and has a closed state and an open state. In the closed state, the cabinet door 12 closes the receiving groove 111 to form a disinfection chamber 101, which includes a primary chamber 102 and a secondary chamber 103 that are connected to each other. In the open state, the receiving groove 111 is exposed. The primary disinfection module 13 is installed on the wall of the primary chamber 102, and the secondary disinfection module 14 is installed on the wall of the secondary chamber 103.

[0038] The technical solution of this utility model, through the above-described scheme, allows the two parts of the probe to be disinfected, with different disinfection requirements, to be respectively assigned to the primary disinfection module 13 and the secondary disinfection module 14 when the probe to be disinfected is placed in the disinfection chamber 101. The primary disinfection module 13 and the secondary disinfection module 14 can perform disinfection of different intensities according to the disinfection requirements of each area of ​​the probe to be disinfected. This achieves the goal of meeting the disinfection requirements, saving energy, and avoiding the additional heat generated by the operation of the disinfection module from affecting the disinfection cabinet 100, which is beneficial to extending the service life.

[0039] The above-mentioned disinfection modules generally use ultraviolet disinfection lamps. The use of disinfection lamps avoids physical contact and can avoid the risk of cross-infection.

[0040] The primary chamber 102 and the secondary chamber 103 can differentiate disinfection intensity from different aspects, such as the comprehensiveness of disinfection. In some embodiments of this invention, both the primary chamber 102 and the secondary chamber 103 are polyhedral spaces, with the primary chamber 102 having a greater number of edges than the secondary chamber 103. This configuration allows the secondary disinfection module 14 to disinfect the probe from multiple different angles, while the primary disinfection module 13 can disinfect the probe more comprehensively from even more angles, thus achieving disinfection level classification. The secondary chamber 103 is generally a quadrangular prism, but it can also be a pentagonal prism. The primary chamber 102 is generally a hexagonal prism, octagonal prism, etc. Preferably, in some embodiments of this invention, the primary chamber 102 is a hexagonal prism, and the secondary chamber 103 is a quadrangular prism.

[0041] Furthermore, in some embodiments of this utility model, the primary disinfection module 13 includes a plurality of first disinfection lamps 131, which are spaced apart on the walls of the primary chamber 102; the secondary disinfection module 14 includes a plurality of second disinfection lamps 141, which are spaced apart on the walls of the secondary chamber 103; the arrangement density of the first disinfection lamps 131 is greater than the arrangement density of the second disinfection lamps 141. In this way, the primary chamber 102 and the secondary chamber 103 can also distinguish disinfection intensity based on the density of the disinfection lamps, thus achieving disinfection level classification. In addition, the inner part of the cabinet door 12 forms one wall of the primary disinfection chamber 101 and part of the secondary disinfection chamber 101. Although the lamp arrangement density of the primary disinfection chamber 101 is high, the area of ​​the wall located on the cabinet door 12 is small, and the disinfection lamps are more concentrated in the cabinet body 11. This helps to reduce the weight of the cabinet door 12, making the weight distribution of the disinfection cabinet 100 more reasonable.

[0042] There is a tiny gap between the cabinet door 12 and the cabinet body 11, which poses a problem of ultraviolet light leakage. Some disinfection cabinets 100 install sealing strips on the cabinet body 11 or the cabinet door 12 to prevent ultraviolet light leakage. However, the ultraviolet intensity of the disinfection lamp is high, and the sealing strip is at risk of cracking under long-term exposure to high-intensity ultraviolet light.

[0043] Based on the above problems, in some embodiments of this utility model, a first assembly structure is provided on the front side of the cabinet 11, forming a receiving groove 111, and a second assembly structure is provided on the inner side of the cabinet door 12. When the cabinet door 12 is closed, the second assembly structure covers the opening of the receiving groove 111, forming a bent light-leakage-proof gap 15. When the cabinet door 12 is open, the receiving groove 111 is exposed outside the cabinet 11. In this application, the cabinet door 12 corresponds to one side of the hexagonal disinfection chamber 101. After the cabinet door 12 is closed, the first disinfection structure on the cabinet door 12 and the second disinfection structure inside the cabinet 11 cooperate, forming a bent gap at the cooperation point, ensuring that ultraviolet light cannot pass through. The aforementioned light-leakage-proof gap 15 has at least one bend; of course, multiple bends can also be provided to prevent ultraviolet leakage and protect the safety of operators and the surrounding environment.

[0044] There are various specific implementations for the second assembly structure covering the receiving groove 111 to form the light-proof gap 15. For example, the second assembly structure is embedded in the groove of the receiving groove 111. Preferably, in some embodiments of this utility model, the first assembly structure is an assembly groove 112, the receiving groove 111 is opened at the bottom of the assembly groove 112, and the second assembly structure is a convex rib 120. In the closed state, the convex rib 120 is located inside the assembly groove 112. The light-proof gap 15 includes a first gap 151 formed between the assembly groove 112 and the convex rib 120, and a second gap 152 between the front side of the cabinet 11 and the inner side of the cabinet door 12, which provides a better light-proof effect.

[0045] In some embodiments of this utility model, the protruding ridge 120 includes a top ridge 121 and a bottom ridge 122. The bottom ridge 122 is formed on the inner side of the cabinet door 12, and the top ridge 121 is formed on the top surface of the bottom ridge 122 in the protruding direction. In the closed state, the bottom ridge 122 is located in the mounting groove 112, and the top ridge 121 is embedded in the groove of the receiving groove 111. The light leakage prevention gap 15 also includes a third gap 153, which is formed between the top ridge 121 and the groove wall of the receiving groove 111, further improving the light leakage prevention effect.

[0046] Considering that a small assembly gap between the receiving groove 111 and the top edge 121 could easily hinder the opening and closing of the cabinet door 12, while an excessively large assembly gap would reduce the light leakage prevention effect, in some embodiments of this utility model, the groove wall of the receiving groove 111 near the groove opening is extended outward, and the periphery of the top edge 121 is set as a first avoidance slope 1211 to cooperate with the groove opening. In this way, when the cabinet door 12 opens and closes, the top edge 121 will avoid the periphery of the groove opening of the receiving groove 111 when rotating with the cabinet door 12. When the cabinet door 12 is closed, the gap between the top edge 121 and the periphery of the groove opening of the receiving groove 111 can be kept within a small range, so as not to hinder the opening and closing of the cabinet door 12, and not to affect the light leakage prevention effect.

[0047] Similarly, in some embodiments of this utility model, a second clearance slope 1221 is provided around the bottom edge 122, and the second clearance slope 1221 is inclined towards the top edge 121 in the convex direction of the bottom edge 122. This also ensures that the cabinet door 12 can be opened and closed without hindering the light leakage prevention effect.

[0048] To further facilitate user operation, in some embodiments of this utility model, the cabinet door 12 is hinged to one side of the front end of the cabinet body 11, and the receiving groove 111 is opened on the front side of the cabinet body 11, away from the side where the cabinet body 11 and the cabinet door 12 are hinged. In this way, when taking out or putting in the probe, even if the cabinet door 12 is opened at a small angle, the distance between the receiving groove 111 and the cabinet door 12 is large enough to facilitate the user to take out the probe.

[0049] In some embodiments of this utility model, the disinfection cabinet 100 further includes a hanging member 16, a receiving groove 111 extending vertically, a primary chamber 102 located below a secondary chamber 103, and a hanging member 16 provided on the top wall of the receiving groove 111 for hanging the equipment 200 to be disinfected. Thus, during use, the probe can be hung on the hanging member 16, with the end of the probe suspended in the primary chamber 102 and the end of the probe near the handle located in the secondary chamber.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
