Description

Technical Field

[0001] The utility model relates to the technical field of disinfection of medical instruments, in particular to a soft endoscope cleaning cavity structure which can be used for cleaning probe-type instruments. Background Art

[0002] In the field of modern medicine, medical probes including transesophageal ultrasound probes and medical endoscopes including gastroscopes, colonoscopes, and colposcopes are often used in the process of examining patients. These medical probes and medical endoscopes, as flexible endoscopes, usually include a functional structure part that contacts the human body and a connecting tube part that connects the functional structure part to the device body.

[0003] In order to prevent cross infection during use, before testing, at least the functional structure part of the equipment that comes into contact with the human body and the part of the tube that extends into the human body need to be cleaned and disinfected. The correct cleaning and disinfection methods can not only reduce the risk of cross infection of patients, but also extend the service life of the equipment.

[0004] In order to improve the cleaning efficiency and cleaning quality, special cleaning equipment is usually used for cleaning the above-mentioned parts. However, most of the existing cleaning equipment is immersion equipment. This type of immersion equipment requires the medical device / parts to be cleaned to be immersed in a cleaning liquid to achieve the cleaning operation, which consumes a large amount of cleaning medium and has high use and maintenance costs. Continuous and long-term immersion can easily cause damage to functional components, and the cleaning effect and efficiency are not as good as rinsing. However, there is no rinsing equipment specially designed for the above-mentioned flexible endoscope instruments and a cleaning chamber structure that cooperates with the rinsing equipment on the market.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0024] See also Figure 1 A preferred embodiment of a cleaning chamber structure of a flexible endoscope is disclosed. In this embodiment, the main part of the cleaning chamber structure is a cylindrical cleaning chamber 1, and the cross-sectional shape of the cleaning chamber 1 is annular, that is, the corresponding inner contour and outer contour of the cylinder are both circular; the top of the cleaning chamber 1 is open, and the opening position is used as an entrance for the part to be cleaned of the probe-type instrument.

[0025] The cleaning chamber 1 is provided with three nozzle assembly seats 2 on the outer diameter of the cylinder structure, and the three nozzle assembly seats 2 are arranged at equal intervals in the height direction of the outer diameter of the cylinder structure. In different embodiments, the nozzle assembly seat 2 can be integrally formed with the cleaning chamber 1 or separately formed for assembly according to actual needs. The nozzle assembly seat 2 in the integrally formed state has better structural stability with the cleaning chamber 1, and the split structure design is convenient for maintenance and function expansion.

[0026] In this embodiment, in order to realize the rapid assembly and disassembly maintenance of the cleaning nozzle 7 assembled on the nozzle assembly seat 2, the nozzle assembly seat 2 and the cleaning chamber 1 are split structures, and are assembled and connected by a detachable assembly method. In order to realize the corresponding detachable assembly function, two vertical guide ribs are formed on the opposite sides of the inner ring surface of the nozzle assembly seat 2, and correspondingly, a vertical guide groove 3 matching the vertical guide ribs and three matching transverse grooves are formed on the outer cylinder surface of the cleaning chamber 1. During assembly, the nozzle assembly seat 2 is inserted into the vertical guide groove 3 through the vertical guide ribs, and is twisted transversely when moved to the corresponding transverse groove position, so that the vertical guide ribs of the nozzle assembly seat 2 are inserted into the transverse groove, and the assembly of the nozzle assembly seat 2 is completed; the three nozzle assembly seats 2 are assembled from bottom to top, and the following is obtained. Figure 1 The assembly structure shown.

[0027] In other embodiments, the detachable assembly method of the nozzle assembly seat 2 on the cleaning chamber 1 can also adopt modular combination assembly, half-joint assembly, limit knot / limit buckle and other annular structures already existing in the prior art on the cylindrical structure.

[0028] A plurality of cleaning nozzles 4 are formed on the nozzle assembly seat 2, and these cleaning nozzles 4 are evenly arranged on the inner annular surface of the nozzle assembly seat 2. The cleaning nozzles 4 are also arranged on the nozzle assembly seat 2 in two ways: integrally formed with the nozzle assembly seat 2 and detachably assembled with the nozzle assembly seat 2. In this embodiment, the cleaning nozzle 4 adopts a split assembly structure that is easy to maintain. The assembly method is to assemble from one side of the cleaning chamber 1 through one of the screw connection, clamping or plug-in methods, and the nozzle assembly seat 2 is formed with an assembly hole at the corresponding position. After the cleaning nozzle 4 is assembled on the cleaning chamber 1, it faces the inside of the cleaning chamber 1, and the direction of the cleaning nozzle 4 (i.e., the extension line of the nozzle axis of the nozzle) maintains an acute angle of 45 to 60 degrees with the axis of the cleaning chamber 1; this acute angle can improve the cleaning effect and cleaning efficiency of the cleaning medium on the surface of the cleaning part to be cleaned during the spraying process, and in order to further optimize the above-mentioned use effect, the corresponding cleaning nozzle 4 can be selected as a wide-angle fan-shaped nozzle with adjustable pressure.

[0029] The cleaning nozzle 4 is supplied with cleaning medium through an external cleaning medium supply pipeline. In different embodiments, the cleaning medium supply pipeline can be directly connected to the corresponding cleaning nozzle 4 on the nozzle assembly seat 2 through multiple branches, or a cleaning medium supply pipeline interface can be provided on the outer ring surface of the nozzle assembly seat 2. The cleaning medium supply pipeline interface is a quick-connect interface that can be quickly assembled and connected with the cleaning medium supply pipeline. In different embodiments, the cleaning medium provided by the corresponding cleaning medium supply pipeline is clean water and / or a cleaning agent, and the corresponding cleaning agent is a combination of any one or more of an enzyme cleaning agent, an alkaline cleaning agent, an acidic cleaning agent, a neutral cleaning agent, and a chlorine-containing disinfectant; and when it is necessary to mix multiple cleaning media, a cavity structure can also be provided in the nozzle assembly seat 2 as a buffer capsule for mixing and temporarily storing the cleaning media, and the buffer capsule is connected to the cleaning medium supply pipeline interface on the outside, and is assembled and connected to the cleaning nozzle 4 on the inside through a leak-proof joint structure; and in order to optimize the reaction conditions of the cleaning agent-type cleaning medium, a heating unit for heating and keeping the cleaning medium warm can also be provided on the corresponding buffer capsule in the nozzle assembly seat 2, and the temperature control of the cleaning process can be achieved through the heating unit, which is used to create reaction conditions that are more conducive to the cleaning media participating in the reaction, including the enzyme cleaning agent, thereby improving the cleaning effect.

[0030] In addition, in order to reduce energy consumption and wastewater discharge, a drainage hole is formed at the bottom of the cleaning chamber 1 to receive the used cleaning medium sprayed from the cleaning nozzle 4. By arranging a container under the drainage hole, the cleaning medium waste liquid generated during the elution process can be recovered, and the recovered cleaning medium waste liquid can be processed and reused to reduce the cleaning cost.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the scope of protection of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the scope of protection defined by the claims attached to this application.
