Description

Technical Field

[0001] This utility model belongs to the field of flexible endoscope cleaning, specifically relating to a protective air gun drying device for flexible endoscopes. Background Technology

[0002] Flexible endoscopes are widely used in the medical field, such as gastroscopes and colonoscopes. After use, they need to be cleaned and dried to prevent residual liquids and stains from damaging the endoscope and causing infection in patients. Currently, air guns are commonly used to dry flexible endoscopes. However, during the drying process, the airflow from traditional air guns directly impacts the inner surface of the flexible endoscope, and the metal surface of the air gun directly rubs against the endoscope interface, easily causing wear and damage to the endoscope surface, shortening its lifespan, and increasing maintenance costs.

[0003] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a device for protecting the air gun drying of flexible endoscopes.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0026] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0027] like Figure 1 As shown, an embodiment of the present invention provides a protective air gun drying device for flexible endoscopes, including an air gun body 1. An air outlet port 101 is provided on one side end face of the air gun body 1, and airflow is ejected from the air outlet port 101 for drying flexible endoscopes.

[0028] like Figures 1 to 2 As shown, a nozzle assembly 2 and a protective assembly 3 are fixed to the middle end face of the air gun body 1. The appropriate nozzle assembly 2 and protective assembly 3 can be selected according to the different flexible endoscope interface specifications to prevent mismatch with the interface specifications of the flexible endoscope, which would cause air leakage and incomplete drying during use. The outer end face of the nozzle assembly 2 is press-fitted with the protective assembly 3. One side end face of the protective assembly 3 has multiple through holes 3021 that match the air outlet port 101. The airflow is ejected from the air outlet port 101 and delivered to the nozzle assembly 2. It is then delivered to the flexible endoscope through the multiple through holes 3021 on the protective assembly 3 to dry the flexible endoscope and prevent the airflow from blowing directly onto the inner surface of the flexible endoscope.

[0029] like Figure 2As shown, the nozzle assembly 2 includes a connecting part 201 and a nozzle 202. One end face of the connecting part 201 has an external thread, and the middle end face of the air gun body 1 has an internal thread matching the external thread. The connecting part 201 is threadedly connected to the air gun body 1, and the nozzle 202 is integrally formed and connected to the other end face of the connecting part 201. Specifically, the external thread at the rear end of the connecting part 201 is aligned with the internal thread of the air gun body 1, and then tightened clockwise. The thread engagement secures the assembly, and a sealing washer ensures a sealed air passage, improving the drying effect and extending the service life of the flexible endoscope.

[0030] Preferably, the connecting part 201 and the air gun body 1 can be connected by a snap-fit ​​method. The rear end of the connecting part 201 is provided with multiple snap-fit ​​parts, and the middle end face of the air gun body 1 is provided with a matching slot. By pressing the snap-fit ​​parts, the snap-fit ​​parts at the rear end of the connecting part 201 are inserted into the matching slots of the air gun body 1, and the snap-fit ​​is reset and tightened to form a sealed connection, thereby allowing the airflow to be delivered to the endoscope through the connector.

[0031] like Figure 3 As shown, the protective component 3 includes a seal 301 and a nozzle sleeve 302. The outer end face of the connecting part 201 is press-fitted with the seal 301. When in contact with the flexible endoscope interface, the flexible material conforms to the endoscope surface, dispersing contact stress and preventing wear on the surface of the flexible endoscope interface. One end face of the seal 301 is fixedly connected to the nozzle sleeve 302 by reinforcing wires 302. Multiple reinforcing wires 302 are wound around multiple end faces in the middle of the nozzle sleeve 302. Multiple reinforcing wires 302 are all heat-fused to the nozzle sleeve 302, and one end face of multiple reinforcing wires 302 is heat-fused to the seal 301, making the connection between the nozzle sleeve 302 and the seal 301 more stable and preventing the nozzle sleeve 302 from falling off due to airflow during use, which could damage the endoscope. The length of the nozzle sleeve 302 is greater than the length of the nozzle 202 to prevent the metal surface of the nozzle 202 from colliding or rubbing against the inner surface of the flexible endoscope during use. The sealing element 301 has a sealing ring 3011 that matches the end of the nozzle sleeve 302 on one side, so as to achieve a sealed connection with the flexible endoscope interface, ensure thorough drying, and prevent residual liquid from damaging the endoscope.

[0032] like Figure 5As shown, the nozzle sleeve 302 has multiple evenly distributed through holes 3021 on one side end face of the nozzle 202 to disperse the airflow and improve the drying effect. A gas distribution block 3022 is located in the middle of the side end face of the nozzle sleeve 302 that is in contact with the nozzle 202. The gas distribution block 3022 matches the nozzle 202 and is frustoconical in shape. The upper base of the gas distribution block 3022 is smaller than the nozzle hole 2021 to facilitate airflow dispersion. The length of the gas distribution block 3022 is less than the gap between the nozzle sleeve 302 and the nozzle 202 to prevent the nozzle sleeve 302 from clogging the nozzle hole 2021 and affecting the drying effect. Simultaneously, it prevents the airflow from directly blowing onto the inner surface of the endoscope, which could damage the endoscope.

[0033] Specifically, the airflow is blown out from the nozzle hole 2021, the air distribution block 3022 guides the airflow to disperse, and then smoothly enters the flexible endoscope through the through hole 3021.

[0034] like Figures 1 to 5 As shown, when using it, first confirm that the specifications of the flexible endoscope interface match the quick connector. Align the flexible endoscope interface with the nozzle assembly 2 and gently push it to make the two initially connect. A seal can be formed by the sealing ring 3011 on the sealing member 301 that matches the flexible endoscope interface. Then turn on the air gun air source.

[0035] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
