Description

Technical Field

[0001] This utility model relates to the field of endoscope drying technology, and in particular to an endoscope cavity drying device. Background Technology

[0002] Because flexible endoscopes come into direct contact with internal organs and are reusable medical devices, they need to be disinfected and dried after use. Drying is an important process to prevent contamination of digestive endoscopes. The lumen and surface of the endoscope must be thoroughly dried. Insufficient drying can lead to a contamination rate as high as 80%, and it can also accelerate the formation of biofilms.

[0003] The surface drying process of endoscopes is simple. In order to facilitate the simultaneous drying of multiple endoscope lumens and to make the overall size of the drying device small and easy to use, an endoscope drying device (publication number CN109998454B) has been developed. It is equipped with one air inlet pipe and multiple air outlet pipes. Each air outlet pipe is used to connect to one endoscope to blow air into the lumen of the endoscope, so as to achieve simultaneous drying of one or more endoscope lumens and reduce labor intensity.

[0004] Existing endoscope drying devices directly blow gas into the endoscope lumen, using cold air to dry the lumen. The temperature difference between the cold air and the humid air and wall inside the endoscope lumen is small, and the continuous blowing of cold air gradually saturates the air inside the lumen, resulting in a relatively long drying time and affecting drying efficiency. In addition, existing endoscope drying devices have a pressure gauge module for each tube to detect air pressure. The number of pressure gauge modules is large, resulting in high operating costs and hindering the reduction of device size. Utility Model Content

[0005] To address the technical problem in the existing endoscope drying devices described in the background art, which use cold air to dry the lumen, resulting in a relatively long drying time and affecting drying efficiency, this utility model provides an endoscope lumen drying device.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides an endoscope cavity drying device, including a housing, a gas source interface and at least one drying pipeline interface on the housing, and a gas heating module inside the housing, located between the gas source interface and the drying pipeline interface. The gas heating module is connected to the gas source interface and the drying pipeline interface respectively through pipelines. The gas heating module can heat the incoming gas. The hot air can accelerate the evaporation of moisture in the endoscope cavity, which greatly shortens the drying time and improves the drying efficiency compared with cold air drying.

[0008] Preferably, a gas flow sensor is installed on the pipeline between the gas heating module and the gas source interface. The gas flow sensor can monitor the gas flow rate entering the gas heating module in real time, and can achieve precise control of the gas flow rate entering the device, ensuring that the appropriate flow rate of gas enters the heating module, which not only guarantees the drying effect, but also avoids the heating efficiency and drying effect being affected by excessive or insufficient flow.

[0009] Preferably, the housing is equipped with a gas distributor, and the gas heating module is connected to multiple drying pipeline interfaces through the gas distributor. The gas distributor can evenly distribute the heated gas to multiple drying pipeline interfaces, thereby enabling the simultaneous drying of multiple endoscopes, greatly improving the drying efficiency and meeting the needs of processing multiple endoscopes at the same time.

[0010] Preferably, a pressure sensor is installed on the gas distributor. The pressure sensor can monitor the gas pressure in the gas distributor in real time, preventing damage to the endoscope lumen due to excessive pressure or affecting the drying effect due to insufficient pressure. This ensures the safety and stability of the entire drying process. Moreover, installing the pressure sensor only on the gas distributor, compared to installing it separately on each pipeline, can reduce costs, simplify wiring and maintenance procedures, facilitate the reduction of the overall size of the drying device, and also make the pressure monitoring more representative.

[0011] Preferably, the gas distributor is connected to all drying pipeline interfaces through several pipelines. Each pipeline between the gas distributor and the drying pipeline interface is equipped with a solenoid valve and a flow switch. The solenoid valve can control the on / off state of each pipeline, making it easy to individually control whether each drying pipeline interface is working, thus improving the flexibility of the device. When the flow switch detects gas flow, it sends a signal to the control board, which then starts to count the drying time of the endoscopes connected to the corresponding channel. At the same time, the flow switch can monitor the gas flow in each pipeline in real time, ensuring that each connected endoscope receives a suitable flow of drying gas, thus guaranteeing the consistency of the drying effect.

[0012] Preferably, the back of the housing is provided with several mounting holes, which facilitate the installation of the device on the wall, workbench or other locations by means of bolts or other fasteners, so that the device is installed firmly and stably, saving space and making it easy to install and arrange flexibly in different places according to actual needs.

[0013] Preferably, a mounting plate is hinged to the back of the housing, and the mounting plate has several mounting holes, which makes it convenient to hang the device at different heights. The mounting holes increase the diversity of mounting methods, making the device installation more convenient and adaptable to various installation scenarios.

[0014] Preferably, the housing contains a battery and a control board, and the housing is equipped with a display screen and a card reader module. The control board is connected to the battery, gas heating module, display screen, and card reader module. The battery provides power. The control board can control the operation of the entire device, such as controlling the heating temperature of the gas heating module and adjusting the gas flow rate based on sensor data. The display screen can intuitively display the device's operating parameters, such as temperature, flow rate, and pressure, allowing operators to understand the device's working status in real time. The card reader module can be used to record operator information, usage time, etc., facilitating equipment management and traceability.

[0015] Preferably, the housing is equipped with a data export module and a data interface. The data export module is connected to the data interface and the control board respectively. The data export module can export the device operation data recorded by the control board, such as drying time, gas flow rate, temperature change, etc., to an external storage device or computer. This facilitates the analysis of the data later and helps with equipment maintenance, performance optimization, and medical quality traceability.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are:

[0017] 1. Equipped with multiple drying pipeline interfaces, it can simultaneously dry multiple endoscopes, greatly improving drying efficiency and meeting the needs of processing multiple endoscopes at the same time; at the same time, a gas heating module is set between the gas source interface and the drying pipeline interface. The gas heating module can heat the incoming gas, and the hot air can accelerate the evaporation of moisture in the endoscope lumen, greatly shortening the drying time and further improving drying efficiency.

[0018] 2. The pressure sensor can monitor the gas pressure in the gas distributor in real time, preventing damage to the endoscope lumen due to excessive pressure or affecting the drying effect due to insufficient pressure. This ensures the safety and stability of the entire drying process. Moreover, installing the pressure sensor only on the gas distributor, compared to setting it separately on each pipeline, can reduce costs, simplify wiring and maintenance procedures, facilitate the reduction of the overall size of the drying device, and also make the pressure monitoring more representative.
