Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1, a cleaning brush device for a soft bronchoscope according to an embodiment of the present invention includes a brush rod 1, a brush 2, and a sponge brush 3. The front end of the brush rod 1 is detachably connected with a brush 2, specifically, the front end of the brush rod 1 is integrally provided with a clamping block 4, the brush 2 is provided with a plurality of brushes 2, the plurality of brushes 2 are different in size and can be used for brushing biopsy channels with different pipe diameters and aspirator pipelines of catheter hoses, and the brush 2 with smaller size can be specially used for brushing smaller parts such as biopsy inlet valves, aspirator buttons, air and water supply buttons and the like; every brush 2 includes that brush axle 21 and hoop set up in the brush hair 22 of brush axle 21 periphery, and card hole 5 has been seted up to brush axle 21 one end, and card hole 5 is used for cooperateing the joint with fixture block 4, is convenient for change not unidimensional brush 2 under different use scenes, and when brush 2 appears damaged, only with change brush 2 can, practice thrift the cost. The shape and structure of the latch 4 and the latch hole 5 are not particularly limited in the present invention, and may be a ring-shaped latching structure similar to the ball and socket engagement shown in fig. 1. The rear end of the brush rod 1 is provided with the sponge brush 3 for adsorbing residues such as sputum and mucus brushed off from the inner wall of the pipeline by the brush 2 at the front end of the brush rod 1, so that the cleaning is more thorough, and the cleaning quality is improved. The sponge brush 3 can be fixedly arranged on the brush rod 1 or detachably arranged on the brush rod 1, and the specific connection mode of the sponge brush 3 and the brush rod 1 is not limited in the utility model.

In a preferred embodiment, the bristles 22 form a cone around the brush shaft 21, the larger diameter end of the cone being located near the snap hole 5, i.e., the smaller diameter end of the cone being located at the forward most end to facilitate insertion into the flexible bronchoscope tube. Furthermore, the diameter of the larger end of the cone is slightly larger than the inner diameter of the soft bronchoscope tube to be cleaned, which is beneficial to scraping and brushing residues adhered on the inner wall of the tube.

As preferred embodiment, brush hair 22 adopts the nylon material, compares current soft brush hair, and is stronger to gluing thick sputum cleaning force, is difficult to have the residue, washs more thoroughly.

In a preferred embodiment, the sponge brush 3 is made of a high-density sponge material. As known by the technical personnel in the field, the high-density sponge is the sponge with the weight of more than 25 kilograms per cubic meter of sponge, has high density, longer rebound resilience than the common sponge, is not easy to collapse, is more wear-resistant and durable, and has better effect of washing the inner wall of the pipeline. Furthermore, the sponge brush 3 is cylindrical and is sleeved on the brush rod 1, the side wall of the sponge brush 3 is wavy, all surfaces of the inner wall of the pipeline can be washed, the surface area of the side wall of the wavy sponge brush 3 is large, and the adsorption effect is better.

As a preferred embodiment, the cleaning brush assembly further comprises a casing 6, and the casing 6 is sleeved on the brush rod 1. Preferably, the sleeve 6 is made of silica gel, so that the protective effect is achieved, the brush rod 1 is prevented from being scraped with the inner wall of the bronchoscope, the wall of the bronchoscope is prevented from being damaged, and the use cost is increased.

As a preferred embodiment, the length of the hair brush 2 and the sponge brush 3 is 3cm-8cm, which plays a role of fully brushing the inner wall of the soft bronchoscope. The length of the brush rod 1 is 80cm-120cm, and is slightly longer than that of the soft bronchoscope, compared with the existing overlong cleaning brush, the collision between a cleaning device and a pipeline in the cleaning process is reduced, and the abrasion to the front side lens of the soft bronchoscope is avoided.
