Description

TECHNICAL FIELD

[0001] The utility model relates to medical cleaning appliance technical field, concretely is a brush for endoscope cleaning. BACKGROUND

[0002] During endoscopy and surgery, contaminants such as blood, mucus, and tissue debris can easily remain in the endoscope lumen. If not thoroughly cleaned, this can lead to cross-contamination or affect the effectiveness of subsequent diagnostic and therapeutic procedures. Therefore, efficient and thorough endoscope cleaning is an important part of medical procedures.

[0003] Existing endoscope cleaning tools mostly use brush structures that clean through the contact and friction of bristles with the inner wall of the lumen. However, traditional brushes have the following significant shortcomings:

[0004] Insufficient foreign object pushing ability: The roots of the bristles are usually directly connected to the brush rod, lacking a dedicated foreign object pushing structure. When the brush is pulled back and forth, it is difficult to effectively push out large foreign objects or solid residues in the lumen, causing some contaminants to remain.

[0005] Poor liquid circulation: When bristles are densely arranged, liquid flow in the lumen is obstructed, and waste liquid and debris generated during the cleaning process can easily accumulate in the gaps between the bristles, causing blockage and affecting cleaning efficiency and effectiveness.

[0006] Limited bristle adhesion and cleaning power: Traditional bristles are mostly straight or simply forked, unable to closely adhere to the curved inner wall of the endoscope lumen, and the direction of the bristles lacks targeted inclination in the cleaning and pushing direction, resulting in insufficient scraping effect on stubborn stains and often requiring repeated operations.

[0007] Single structure design: The number and distribution of existing brush heads are fixed, making it difficult to adapt to endoscope lumens of different diameters and lengths, resulting in incomplete coverage during a single cleaning, the need for multiple adjustments of brush head positions, and an increased workload for medical staff.

[0008] Although existing technologies have optimized cleaning effects through soft brush petals and multi-stage hardness brush bodies, there is still room for improvement in terms of foreign object pushing, liquid circulation, and the impact of bristle structure on cleaning efficiency. The utility model effectively solves the above problems by setting up an elastic membrane and small holes at the root of the bristles and optimizing the fork angle and inclination direction of the bristles, significantly improving the convenience and thoroughness of endoscope cleaning.

[0030] The utility model will be described in detail below in combination with the drawings.

[0031] In order to make the utility model purposes, technical scheme and advantages more clearly, the following is in combination with the drawings and examples, the utility model is further described in detail.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0032] Example one

[0033] In this embodiment, as shown in Figure 1 A brush for cleaning endoscope includes a brush body and a pole body, the brush body includes a plurality of brush heads, each brush head includes bristles and a film arranged at the root of the bristles, and a plurality of small holes are arranged on the film; the bristles are bifurcated near the brush head, and the bristles are inclined to the cleaning advancing direction; the pole body is connected with the brush body.

[0034] As shown in Figure 1 The brush includes a pole body 1 (length 30 cm, diameter 3 mm) and three brush heads 2 (distributed with an interval of 5 cm). The root of the bristles 3 of each brush head 2 is fixedly connected with a 0.3 mm thick medical silica gel film 4, the film covers 80% of the cross-sectional area of the brush head, and the edge exceeds the root of the bristles by 1 mm. The bristles 3 are made of nylon material, are bifurcated into two strands at a distance of 5 mm from the top end of the brush head, the bifurcation angle is 45°, and the whole is inclined to the advancing direction of the brush head by 30°.

[0035] Application scenario: when cleaning the lumen of a gastroscope (inner diameter 2.8 mm), the film 4 is inserted into the lumen along with the bristles 3, and in the reciprocating pulling process, the film pushes out the blood clots at the bottom of the lumen by flexible deformation.

[0036] Beneficial effects:

[0037] The physical barrier effect of the film 4 improves the foreign matter removal rate; the bifurcation of the bristles increases the contact area of the inner wall of the lumen, and the inclined angle improves the scraping efficiency of mucus.

[0038] Example two

[0039] Further, the film is matched with the inner diameter of the endoscope and is made of elastic material, which can effectively push out the foreign matter in the endoscope during the advancing process.

[0040] The film 4 adopts a medical-grade TPU elastomer (Shore hardness 80A) with a thickness of 0.2 mm. Compared with the silicone film of the comparative example 1, the TPU material has a tensile strength of 40 MPa and an elongation at break of 500%.

[0041] When cleaning the endoscope, the film 4 can be deformed with the lumen bending without creases, thereby avoiding scratching the precise mirror surface.

[0042] The elastic material has a large deformation recovery rate, and still maintains the pushing performance after being used repeatedly for 50 times.

[0043] The flexible contact avoids the mechanical damage of the traditional hard-brush to the mucosa of the endoscope.

[0044] Further, the small holes are uniformly distributed on the film with a pore size of 0.5-2 mm, which facilitates the passage of liquid and prevents blockage.

[0045] The film 4 is uniformly distributed with round holes (hole spacing 2 mm), and the hole diameter can be adjusted according to the type of endoscope: φ0.5 mm hole for pediatric endoscope, and φ2 mm hole for gastrointestinal endoscope.

[0046] The liquid passage rate of the small hole 5 is improved, and the cleaning time is shortened; the hole structure forms a pressure difference on both sides of the film 4, thereby avoiding secondary pollution caused by liquid retention.

[0047] Further, the bifurcation angle of the bristles is 30°-60°, so that the bristles can better fit the inner wall of the endoscope lumen during cleaning.

[0048] The bifurcation angle of the bristles 3 is designed in grades: narrow section (such as common bile duct) brush head: bifurcation angle 30°, single bristle diameter 0.1 mm; wide section (such as stomach cavity) brush head: bifurcation angle 60°, single bristle diameter 0.2 mm.

[0049] The bifurcation design reduces the angle of bristle deflection and improves the wall coverage rate; the multi-bifurcation structure increases the gap between the bristles and reduces the entanglement of hair-like foreign matter.

[0050] Further, the inclination angle of the bristles to the cleaning direction is 15°-45°, which enhances the scraping effect on the residues.

[0051] Primary washing brush head (proximal end): inclination angle 15°, which reduces the irritation to the mucosa;

[0052] Fine washing brush head (distal end): inclination angle 45°, which enhances the peeling force on the biofilm.

[0053] When cleaning the enteroscope, the distal brush head scrapes the folds of the intestinal wall at an angle of 45°, which, in combination with the water flow impact, improves the removal rate.

[0054] The inclination angle causes the contact stress of the bristles to be concentrated on the tip, which enhances the peeling force on the dry and hardened stains; the gradient angle design avoids the “pushing effect” of the traditional straight bristles, thereby preventing the foreign matter from being pushed into the deep lumen.

[0055] Further, the brush head is arranged at 2-5, spaced along the axial direction of the rod body, which can clean the endoscope lumen for multiple times.

[0056] Short endoscope (such as cystoscope, length 40 cm): 2 brush heads (interval 10 cm);

[0057] Long endoscope (such as small intestine mirror, length 200 cm): 5 brush heads (interval 30 cm).

[0058] When cleaning the small intestine mirror, 5 brush heads cover the whole section, and single insertion can complete the cleaning (traditional 3 times insertion and extraction).

[0059] The multi-brush head design improves the lumen coverage rate and avoids the cleaning blind area; the interval distribution reduces the interference between the brush heads and the water flow resistance.

[0060] Further, the rod body is provided with anti-slip lines, which is convenient for medical staff to hold and operate.

[0061] The surface of the rod body 1 is injection molded with medical soft glue to form a diamond-shaped anti-slip line 6, and the holding section length is 8 cm.

[0062] The line design increases the friction coefficient between the glove and the rod body, reduces the operation failure rate; the soft glue material buffers the hand pressure, and reduces the fatigue after continuous operation.

[0063] Further, the rod body and the brush body are detachably connected, which is convenient for replacing the brush head.

[0064] The rod body 1 and the brush body are connected by quick release buckle: the rod body top end is provided with 3 elastic clamping jaws, and the brush body tail part is provided with an annular clamping groove, which can be separated by pressing.

[0065] After the brush head is contaminated, it is replaced within 10 seconds without the need for overall discarding (the traditional brush needs to replace the whole).

[0066] The single use cost is reduced; the modular design supports the interchange of different specifications of brush heads, and adapts to more than 90% of endoscope models.

[0067] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
