Description

Pipeline cleaning tool

Technical Field

The invention relates to an appliance, in particular to a brush body.

Background

Medical endoscopes are used to perform surgical procedures such as biopsy sampling, drug injection, tissue removal, etc. through instrument channels. The instrument channel must be thoroughly cleaned each time after surgery to avoid microbial growth or cross-contamination. Since the instrument channel of the endoscope is very long and thin, a cleaning brush is basically used as a decontamination tool for thorough cleaning during cleaning.

The conventional design of the existing cleaning brush is a metal or plastic long guide wire, and brushes are arranged at two ends or one end of the long guide wire, so that the effect of cleaning residues on the tube wall is achieved by repeatedly washing, brushing and rinsing.

The current common cleaning brushes are generally simple cleaning brushes, namely, the brush and the guide wire are fixedly attached, the brush moves axially along the tube wall under pushing or pulling, the movement track of the brush is single, gaps exist among the bristles, residues on the tube wall are pushed in a single direction, and the overall cleaning effect is poor; meanwhile, the simple cleaning brush needs different manufacturing processes of weaving of the brush and bonding of the end part, and the manufacturing cost is higher.

Therefore, aiming at the existing simple cleaning brush scheme, people also provide various improved schemes to further improve the cleaning effect.

If the existing pipe wall cleaning brush is a brush with a guide wire and an end part, in order to achieve a better cleaning effect, the end part is provided with a metal spring wire structure, the brush can move in multiple directions in the pipe wall under the pushing or pulling action, and the better cleaning effect is achieved.

In addition to the problems of construction and cost, such washing brushes with brushes present a major safety problem during their application. If such a brush-equipped washing brush is used to wash instruments used for highly contagious pathogens, or is not completely sterilized after use, it is itself very likely to form a source of contamination, exposing the next endoscope to the risk of contamination.

The utility model discloses a chinese utility model patent of publication No. CN 21069692U discloses an endoscope cleaning brush, and it includes plastics brush-holder stud and soft brush head, and soft brush head includes a plurality of discoid soft brush lamella, and the coaxial interval of soft brush lamella is fixed in the nearly front position of plastics brush-holder stud. This scheme adopts soft brush head to replace original brush hair, but disk-shaped soft brush lamella must interference fit just can guarantee to seal closely with abluent pipeline wall, when disk-shaped soft brush lamella was used in the pipeline of less diameter, because the circumference compression, the edge can the fold rather than smooth subsides at the pipeline inner wall, influences to strike off abluent effect. The soft brush flap perpendicular to the guide wire can apply axial pushing or pulling force to the tube wall when the foreign matter passes through the soft brush flap, so that the foreign matter with strong adhesiveness is difficult to remove.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

The conventional cleaning brush adopts a design scheme of a hairbrush, has the defects of unsatisfactory cleaning effect, high manufacturing cost and great possibility of becoming a pollution source in the using process. Aiming at the situation, the invention abandons the design concept of the conventional cleaning brush, namely, the cleaning brush is not adopted, but the scrapers arranged at different angles are adopted, so that the effect of removing the residues on the tube wall more efficiently can be achieved in the same operation process compared with the conventional cleaning brush.

As the blade, a soft blade is preferable in the present invention for the purpose of easy use and efficient cleaning by scraping.

Referring to fig. 1, an exemplary embodiment of an embodiment of the present invention is shown.

This example embodiment shows a pipeline cleaning tool 100, which is mainly composed of a guide wire 110, several segments of a first scraper 120, and a second scraper 130.

The plurality of segments of the first scraping plates 120 are vertically arranged on the outer side wall of the front segment of the guide wire 110 according to different angles, and each segment of the first scraping plates 120 is obliquely distributed at a certain angle relative to the axial direction of the guide wire 110, so that a scraping plate area which extends along the axial direction of the guide wire and circumferentially covers the outer side surface of the guide wire is formed at the front segment of the guide wire 110.

In addition, the first scraper 120 in this embodiment is preferably made of a corresponding flexible material, such as a rubber scraper, a silicone scraper, etc., but not limited thereto.

The height of the first scraper 120 can be determined according to actual requirements, and is preferably such that the overall size (e.g., diameter) of the scraper region on the cleaning tool 100 is greater than the inner diameter of the part to be cleaned (e.g., the pipe to be cleaned). To facilitate operation, the overall size (e.g., diameter) of the squeegee field is generally slightly larger than the inner diameter of the member to be cleaned (e.g., the wall of the tube to be cleaned).

The first blade 120 thus provided forms a flexible blade region circumferentially covering the outer surface of the guide wire at the front end of the cleaning tool 100 as a cleaning member. Thus, when the cleaning tool 100 is used, the front section with the flexible scraper region can be integrally inserted into a component to be cleaned (such as a pipe wall to be cleaned), and then the plurality of sections of the first scrapers 120 forming the flexible scraper region respectively deform to a certain extent, and the top end of each section of the first scrapers 120 abuts against and is attached to the inner wall of the component to be cleaned (such as the pipe wall to be cleaned), so that when the cleaning tool is located in the component to be cleaned (such as the pipe wall to be cleaned) to move back and forth, the whole top end of each section of the first scrapers 120 forms relative friction with the inner wall of the component to be cleaned (such as the pipe wall to be cleaned), and then the whole top end of each section of the first scrapers 120 forms a scraping action on the inner wall of the component to be cleaned (such as the pipe wall to be cleaned).

The whole top end of each section of the first scraper 120 is abutted and attached to the inner wall of the part to be cleaned (such as the pipe wall to be cleaned), so that the length of the whole top end of each section of the first scraper 120 forms a corresponding scraping surface, and the inner wall of the part to be cleaned (such as the pipe wall to be cleaned) which is abutted along the scraping surface is scraped and cleaned.

Moreover, because the flexible scraper plate areas formed by the plurality of sections of the first scraper plates 120 circumferentially cover the outer side surface of the guide wire, scraping surfaces formed by the plurality of sections of the first scraper plates 120 forming the flexible scraper plate areas are matched with each other, and a scraping surface capable of continuously covering at least one circle of the inner wall of the part to be cleaned (such as the pipe wall to be cleaned) along the circumferential direction is formed, so that the inner wall of the part to be cleaned (such as the pipe wall to be cleaned) can be continuously scraped and cleaned without gaps along the circumferential direction, and efficient cleaning is realized.

Referring to fig. 2, the first scraper 120 of the present embodiment is specifically configured in a shape of a thin fin with moderate height or a thin fin with thick bottom, preferably a thin fin with thick bottom and thin inner side and thin outer side, so as to ensure that the top side is soft enough, and when the first scraper is inserted into the pipe of the member to be cleaned, the top side is slightly bent to be close to the member to be cleaned (e.g., the pipe wall to be cleaned).

Moreover, the first scrapers of the two sections are arranged oppositely along the direction of the guide wire, and through the simple design, a gapless, multi-angle and multi-direction scraping effect can be provided during brushing, so that efficient cleaning is realized.

The first scraper 120 with such a structure may be produced by injection molding, but is not limited thereto, and any other feasible solution may be adopted according to the needs.

By way of example, the first scraper 120 may be formed as a one-piece injection molded part that is bonded, e.g., glued, to the wire 110 at the ends.

Alternatively, the guide wire 110 may be inserted and bonded when the end of the scraper 120 is injection molded, with the central shaft being hollow.

The following illustrates a configuration scheme in which a plurality of segments of the first scraper 120 form corresponding flexible scraper regions on the outer side surface of the guide wire in the present embodiment.

In this example, each segment of the first scraper 120 is spirally distributed on the outer sidewall of the guide wire 110. The form of the spiral can be determined according to actual requirements.

The plurality of segments of the first scraping plates 120 distributed on the outer side wall of the guide wire 110 in a spiral form are respectively distributed and distributed along the circumferential direction and the axial direction of the guide wire in a matching way.

Specifically, the plurality of first scraping plates are distributed along the circumferential direction of the guide wire, and the plurality of first scraping plates in each section are distributed in a mutually parallel complementary structure and can cover one circumferential surface of the guide wire.

As shown in the figure, in the illustrated embodiment, two

first scrapers

121, 122 are distributed in the first segment, the two

first scrapers

121, 122 are distributed oppositely along the circumferential direction of the guide wire, and are distributed in a mutually parallel structure based on a spiral form of the two

first scrapers

121, 122, so that the scraping surfaces formed by the two

first scrapers

121, 122 are complementary to each other, so as to continuously cover one circumferential surface of the guide wire. In the other distribution layers, the same arrangement is used.

Meanwhile, in the axial direction of the guide wire, a plurality of sections of first scraping plates are sequentially distributed along the axial direction of the guide wire, and the extending directions of the two adjacent sections of first scraping plates relative to the axial direction of the guide wire are opposite.

In the illustrated embodiment, the first scraping plates 121 in the first section and the first scraping plates 123 in the second section are matched end to end along the axial direction of the guide wire, and are distributed in sequence; meanwhile, the spiral extending direction of the first scraper 121 relative to the axial direction of the guide wire 110 is opposite to the spiral extending direction of the first scraper 123 relative to the axial direction of the guide wire 110. Between other distribution layers, and so on. Therefore, through the reverse distribution between the two adjacent sections of the first scraping plates along the axial direction of the guide wire, a gapless multi-angle multi-directional scraping effect can be provided.

It should be noted that the range (e.g., length) of the flexible scraper region formed at the front section of the guide wire 110 may be determined according to practical requirements, and is not limited herein. In the illustrated embodiment, the flexible blade region formed at the front end of the guide wire 110 is provided in accordance with the above-described embodiment, and 2 segments are formed in total, but the present invention is not limited thereto, and 3 or more segments may be used.

On the basis of the above-mentioned configuration of the cleaning tool 100, in this embodiment, a plurality of second scrapers 130 are further disposed at the front section of the guide wire 110 for cooperating with a plurality of first scrapers 120 at the front section of the guide wire 110, so as to improve the scraping effect.

Specifically, the second scrapers 130 are respectively disposed on the outer sidewall of the guide wire perpendicularly to the axial direction of the guide wire, so as to scrape from different angles and directions relative to the first scrapers 120, thereby improving the scraping effect.

Preferably, the second scraper 130 is made of a flexible material, such as a rubber scraper, a silicone scraper, etc., but not limited thereto.

In practical applications, the second scraper 130 preferably has a ring-shaped structure, and can be formed by injection molding, but is not limited thereto, and any other feasible scheme may be adopted as needed.

For example, the annular second scraper 130 is designed as an integral injection molding and can be fixedly combined with the guide wire 110, and the specific combination manner is not limited herein and can be determined according to actual requirements.

The size of the annular second scraper 130 can be determined according to actual requirements, and it is preferable that the overall size (e.g., diameter) of the annular second scraper 130 is larger than the inner diameter of the member to be cleaned (e.g., pipe to be cleaned). For ease of operation, the annular second scraper 130 generally has an overall dimension (e.g., diameter) that is slightly larger than the inner diameter dimension of the member to be cleaned (e.g., the wall of the pipe to be cleaned).

The second scraper blade 130 that sets up from this is inserting along with leading in cleaning means 100 is whole to wait to wash the part (if wait to clean the pipe wall), and certain deformation will take place respectively for the time, and the outside end of every second scraper blade 130 will be pasted closely with the inner wall butt of waiting to wash the part (if wait to clean the pipe wall), can paste the inner wall a week of waiting to wash the part (if wait to clean the pipe wall) by the butt simultaneously. Thus, when the cleaning tool is located in the member to be cleaned (e.g., the pipe wall to be cleaned) to move back and forth, the outer end of each second scraper 130 will form relative friction with the inner wall of the member to be cleaned (e.g., the pipe wall to be cleaned), and then the outer end of each second scraper 130 will form a scraping action for one circle of the inner wall of the member to be cleaned (e.g., the pipe wall to be cleaned).

The outer end of each second scraper 130 is integrally abutted and attached to the inner wall of the member to be cleaned (such as the pipe wall to be cleaned), so that each second scraper 130 forms a corresponding annular scraping surface along the entire outer end thereof, and can be synchronously abutted to the inner wall of the member to be cleaned (such as the pipe wall to be cleaned) for a circle and scraped for cleaning.

In order to ensure the fitting of the part to be cleaned (such as the pipe wall to be cleaned) and the annular second scraper 130, the end of each second scraper 130 is designed with a plurality of openings 131, so that wrinkles generated when the second scraper 130 is fitted with the part to be cleaned (such as the pipe wall to be cleaned) are reduced.

The number of the openings 131 of each second scraper 130 can be determined according to practical requirements, and is not limited herein. The openings 131 in each second scraper 130 are preferably arranged in an evenly distributed manner.

For the second scraper 130 configured in such a manner, the second scraper is preferably disposed at the front of the flexible scraper region formed by the plurality of segments of the first scraper 120, i.e., between the flexible scraper region formed by the plurality of segments of the first scraper 120 and the top end of the guide wire 110.

The number of the second scrapers 130 can be determined according to actual requirements, and the openings 131 between two adjacent second scrapers 130 are arranged in a staggered manner. In the illustrated embodiment, two second scraping plates 130 are provided, and the openings of the two second scraping plates 130 are arranged in a staggered manner, so that no dead angle is formed during scraping and cleaning, and scraping is ensured to be clean.

In addition to the above-mentioned configuration of the cleaning tool 100, the ball 140 is further disposed at the top end of the guide wire 110, and the ball 140 forms a corresponding protective block to prevent the tip of the guide wire from damaging the cleaned tube wall.

It should be noted that other blunt spherical bodies may be used to form the corresponding protective block structure.

Pipeline cleaning tool 100 that this example given forms multiunit circumference continuous distribution's scraping face respectively through the scraper blade (if a set of first scraper blade and a set of second scraper blade) of at least two sets of different design angles and distribution mode, and every group scrapes the face and can both treat cleaning element (if treat clean pipe) inner wall circumference a week and accomplish to scrape off cleanly, treats cleaning element (if treat clean pipe) inner wall then and carries out multiunit circumference continuous synchronous scraping cleanly, guarantees no dead angle, the cleanness of no omission.

The pipeline cleaning tool 100 abandons the design of a conventional brush, innovatively adopts a soft scraper, the whole size is slightly larger than the inner diameter of the pipeline, and after the cleaning brush enters the conduit, the top end of the scraper deforms slightly and is tightly attached to the wall of the conduit. When the cleaning brush is pushed or pulled, the plurality of groups of the scraping plates distributed in different angles, different directions and different modes can carry out circumferential integral cleaning on the inner wall of the part to be cleaned (such as a pipe to be cleaned), thereby achieving the cleaning effect.

In the illustrated embodiment, the front section of the pipe cleaning tool 100 is provided with a plurality of first scrapers 120 along the axial direction, and each first scraper 120 is disposed at an angle along the axial direction of the tool, and the specific distribution is as described above.

When a tool cleans a part to be cleaned (such as a pipe to be cleaned) by the aid of the plurality of sections of first scraping plates 120 distributed in the way, when a certain section of the first scraping plate 120 touches residues on the pipe wall, the first scraping plate 120 is subjected to vertical thrust given by the guide wire, so that friction force tangent to contact surfaces of the first scraping plate 120 and the pipe wall is formed between the first scraping plate 120 and the pipe wall, and the residues on the pipe wall are scraped accordingly; meanwhile, since the first scrapers 120 adjacent to the segment of the first scrapers 120 in the axial direction are distributed in a direction and angle complementary to the segment of the first scrapers 120, if the wall residue passes through two consecutive segments of the first scrapers, the wall residue is subjected to opposite forces. Therefore, the residues can not be adhered to the pipe wall by pushing the tool back and forth, and the effect of cleaning the pipe wall more effectively is achieved.

In conjunction with this, the pipe cleaning tool 100 is further provided with a plurality of annular second scrapers 130 at the ends thereof. Because the second scraper 130 is arranged in the axial direction perpendicular to the guide wire, the scraping force formed by the second scraper 130 on the tube wall is different from that of the first scraper 120, namely, the tube wall residue is subjected to the scraping force in the other direction, so that the scraping effect is improved; meanwhile, the two adjacent second scrapers 130 are arranged in a staggered manner, so that no dead angle exists in the movement process, the residues are taken out of the pipeline, and the pipe wall is scraped clean.

Pipeline cleaning tool 100 adopts the scraper blade in this scheme, does not have the clearance that the brush can't avoid, provides more effectual cleaning. In practical application, a large amount of injection molding production can be carried out by using a mold, the guide wire can be made of metal or plastic products, the production is easy, the manufacturing cost is reduced, the disposable use is convenient, and the cross infection risk is avoided.

Finally, based on the design of the present invention, different angles and different combinations can be adopted for the first scraper 120, and the present invention is not limited to the above embodiment, and can achieve excellent cleaning effect.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
