Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, in particular to a cleaning device for endoscopes in the gastrointestinal department. Background Art

[0002] Digestive endoscopy (endoscopy) is the most effective method for early screening and diagnosis of digestive tract cancer. Qualified disinfection of endoscopes is the premise and basis for safe diagnosis and treatment. Endoscopes are difficult to clean and disinfect due to their complex structure, narrow and long pipes, and their own design problems.

[0003] A major reason for the failure of endoscope cleaning and disinfection is the formation of biofilm. Studies have shown that there are mostly scratches inside the tubes of endoscopic forceps, and microorganisms can easily remain in these gaps, leading to the formation of biofilm. The bacterial biofilm can firmly adhere to the inner surface of the tube, hindering the penetration of the sterilization medium and causing sterilization failure. Therefore, it is particularly important to effectively remove the biofilm in the tube.

[0004] Foreign guidelines point out that the most important step in the endoscope reprocessing process is cleaning, and the scrubbing process in the cleaning is the key step to remove the biofilm in the endoscope channel; however, in actual clinical work, the scrubbing operation is time-consuming and labor-intensive, and the endoscope turnover is fast, which is prone to inadequate scrubbing or missed scrubbing, resulting in unclean cleaning of the endoscope channel, and the residual biofilm in the channel is not completely removed, increasing the risk of hospital infection; therefore, it is necessary to propose a gastroenterology endoscope cleaning device. Utility Model Content

[0005] The utility model aims to provide a cleaning device for gastroenterology endoscopes, which expands an airbag tube by filling it with a non-Newtonian fluid, forms a plurality of small balloons under the limit of a deformed grid, and the small balloons cooperate with rubber protrusions to contact the side wall of an endoscope channel for brushing; utilizes the characteristics of the non-Newtonian fluid, changes the softness and hardness of the airbag tube during brushing by changing the impulse, and performs fixed-point adaptive brushing on the biofilm remaining in the endoscope channel, thereby reducing the occurrence of inadequate brushing or missed brushing and the like.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a digestive endoscope cleaning device, comprising an air bag tube for conveying non-Newtonian fluid, the air bag tube being conveyed into the endoscope channel through a guide wire; a plurality of rubber protrusions are provided on the outer surface of the air bag tube;

[0007] The airbag tube is provided with a plurality of deformable grids; the deformable grids are composed of a plurality of movable polygons, and adjacent movable polygons are hinged to each other; a drawstring for pulling the deformable grid is fixedly connected to the bottom of each deformable grid, and the deformable grid is deformed and contracted under the pulling of the drawstring.

[0008] The following principles and beneficial effects are achieved by adopting the above scheme:

[0009] The balloon tube is guided into the endoscope channel by a guide wire, and the operator delivers a non-Newtonian fluid into the balloon tube. Prior to this, the operator ensures that the front end of the balloon tube is lower than the rear end of the balloon tube. The non-Newtonian fluid can flow to the front end of the balloon tube under the action of gravity. Under the filling of the non-Newtonian fluid, the front end of the balloon tube expands. At this time, the pull rope connected to the deformable grid is pulled, and the deformable grid contracts under the pulling action. Under the contraction action of the deformable grid, the front end of the balloon tube is divided. At this time, the front end of the balloon tube expands and protrudes on the deformable grid, and multiple small balloons are formed on the surface of the deformable grid. , the small balloon cooperates with the rubber protrusion to contact the side wall of the endoscope tube for brushing; in this process, using the characteristics of non-Newtonian fluid, when the impulse of pulling the pull rope is large, the non-Newtonian fluid becomes hard under the action of the large impulse, so that the front end of the airbag tube becomes hard; when the impulse of pulling the pull rope is small, the non-Newtonian fluid is still relatively soft under the action of the small impulse, so that the front end of the airbag tube is still relatively soft; therefore, the user can adjust the hardness of the airbag tube according to the shape and structural characteristics of the part to be brushed, and perform fixed-point adaptive brushing on the biofilm remaining in the endoscope tube. After filling the front end of the airbag tube, the middle, lower middle, and lower parts of the airbag tube can be filled in turn by the above method, and the hardness of different parts of the airbag tube can be changed by the above method. Since the airbag tube is relatively soft compared to rigid materials, it is not easy to scratch the side wall of the inner tube of the endoscope during the brushing process.

[0010] The difference between the utility model and the prior art lies in that: the balloon tube is expanded by filling with non-Newtonian fluid, and a plurality of small balloons are formed under the limitation of the deformed grid, and the small balloons cooperate with the rubber protrusions to contact the side wall of the endoscope channel for brushing; the characteristics of the non-Newtonian fluid are utilized, and the softness and hardness of the balloon tube are changed by changing the impulse during brushing, so that the biofilm remaining in the endoscope channel is brushed adaptively at a fixed point, thereby reducing the occurrence of inadequate brushing or missed brushing.

[0011] Furthermore, different pull cords have different colors to distinguish the deformed grids at different positions.

[0012] Beneficial effect: When cleaning the endoscope channel through the balloon tube, it is necessary to pull the deformed grids at different positions. In order to distinguish the deformed grids at different positions, different pull ropes are set to different colors, so that it is easy for the operator to distinguish.

[0013] Furthermore, the front end of the airbag tube is conical.

[0014] Beneficial effect: Compared with the conventional round-headed front end, the conical front end reduces the diameter of the front end of the airbag tube, making it easier for the front end of the airbag tube to pass through the endoscope channel.

[0015] Furthermore, the rear end of the airbag tube is connected to a gripping portion.

[0016] Beneficial effect: When conveying non-Newtonian fluid into the airbag tube, the airbag tube can be supported by holding the holding portion, and the design of the holding portion increases the contact area between the operator's hand and the airbag tube, thereby improving the stability of the operator when holding the airbag tube.

[0017] Furthermore, anti-slip patterns are engraved on the grip portion.

[0018] Beneficial effect: Compared with conventional smooth surfaces, the anti-slip pattern can increase the friction between the operator's hand and the gripping part, thereby increasing the stability of the operator when holding the gripping part.

[0019] Furthermore, a through hole is formed on the gripping portion, and an end of the pull rope away from the deformable grid passes through the through hole.

[0020] Beneficial effect: Since there are multiple pull ropes, when the pull ropes follow the airbag tube into the endoscope tube, the pull ropes may be entangled and unable to be positioned. Therefore, the pull ropes are passed through the through holes, and the through holes here can limit the pull ropes to a certain extent.

[0021] Furthermore, it also includes a cleaning box, which is composed of a base, and the tops of the two lengthwise side walls of the base are respectively fixedly connected with a support plate and a bracket, and a cleaning pool is fixedly connected between the support plate and the bracket; the bottom of the cleaning pool is connected with a water pipe, and a valve is connected in the water pipe, and one end of the water pipe away from the cleaning pool passes through the support plate;

[0022] A sliding groove is provided on the side wall of the bracket, a sliding rod is provided in the sliding groove for horizontal sliding cooperation, a vertical rod is hingedly connected to the end of the sliding rod away from the sliding groove, and a fixing part for engaging the endoscope is fixedly connected to the end of the vertical rod away from the sliding rod; a nozzle is provided above the sliding groove, and the nozzle is hinged to the side wall of the bracket.

[0023] Beneficial effects: After using the endoscope, place the endoscope in the cleaning pool, and use enzyme-containing washing gauze to wipe the surface of the endoscope; connect the nozzle to the external water source; water flows out through the nozzle, and the nozzle can be turned to change the spray angle of the nozzle. When the cleaning pool is full of water, completely immerse the endoscope and accessories in the water to observe whether there are bubbles. If there is a leak, there is a leak point where the air leaks. Open the valve, drain the water in the cleaning pool, and use the flowing water to rinse the outer surface of the endoscope; when brushing the endoscope pipeline, pass one end of the endoscope through the fixed part in turn, slide the slide bar to straighten the endoscope; brush the endoscope pipeline through the airbag tube. After brushing the endoscope channel and preparing a special cleaning enzyme solution, remove the endoscope from the fixed part, put the cleaning enzyme solution into the cleaning tank, and soak the endoscope and accessories for 3 to 5 minutes; drain the enzyme solution, rinse the endoscope body and accessories in clean water, use an irrigation device to clean the endoscope channel until the enzyme solution disappears completely, use a high-pressure spray gun to blow out excess water, and dry the endoscope to avoid diluting the disinfectant; drain the clean water, fully soak the slightly dried endoscope and accessories in the disinfectant, use an irrigation device to fill the endoscope channel with disinfectant, and clean the disinfectant after 5 to 10 minutes; the operator changes the gloves, drains the disinfectant, takes out the endoscope and accessories, opens the nozzle again, rinses the endoscope with running water, wipes the endoscope body, blows dry, and puts it away for use.

[0024] Furthermore, a plurality of universal wheels are fixedly connected to the bottom of the base.

[0025] Beneficial effect: The universal wheel has strong flexibility, and the cleaning box can be transferred by the universal wheel according to the actual use environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The embodiment is basically as shown in the attached Figure 1-2 As shown:

[0031] A digestive endoscope cleaning device comprises an air bag tube 10 for conveying non-Newtonian fluid, the air bag tube 10 is conveyed into an endoscope channel through a guide wire; a plurality of rubber protrusions are integrally formed on the outer surface of the air bag tube 10;

[0032] The airbag tube 10 is integrally formed with a plurality of deformable grids 13 ; the deformable grids 13 are composed of a plurality of movable polygons, and adjacent movable polygons are hinged to each other; a pull rope 12 for pulling the deformable grid 13 is integrally formed at the bottom of the deformable grid 13 , and the deformable grid 13 is deformed and contracted under the pulling of the pull rope 12 .

[0033] Different pull ropes 12 have different colors and are used to distinguish the deformed grids 13 at different positions. The front end of the airbag tube 10 is conical. The rear end of the airbag tube 10 is connected to a gripping portion 11. The gripping portion 11 is engraved with anti-slip grooves. A through hole is opened on the gripping portion 11, and the end of the pull rope 12 away from the deformed grid 13 passes through the through hole.

[0034] The cleaning box is also included, which is composed of a base 1. The tops of the two lengthwise side walls of the base 1 are respectively fixedly connected with a support plate 2 and a bracket 4 by bolts, and a cleaning pool 3 is fixedly connected between the support plate 2 and the bracket 4 by bolts; a water pipe 9 is connected to the bottom of the cleaning pool 3, a valve is connected to the water pipe 9, and an end of the water pipe 9 away from the cleaning pool 3 passes through the support plate 2;

[0035] A slide groove 5 is provided on the side wall of the bracket 4, and a slide rod 6 is laterally slidably fitted in the slide groove 5. The end of the slide rod 6 away from the slide groove 5 is hinged with a vertical rod, and the end of the vertical rod away from the slide rod 6 is fixedly connected with a fixing part 7 for engaging the endoscope by bolts; a nozzle 8 is provided above the slide groove 5, and the nozzle 8 is hinged to the side wall of the bracket 4.

[0036] The bottom of the base 1 is fixedly connected with a plurality of universal wheels by bolts.

[0037] The specific implementation process is as follows:

[0038] The first step is to place the endoscope in the cleaning tank 3 after use, and wipe the surface of the endoscope with gauze containing enzyme washing solution; connect the nozzle 8 to the external water source, and the external water source of this embodiment can be a water pump; water flows out through the nozzle 8, and the nozzle 8 can be turned to change the water spraying angle of the nozzle 8. When the cleaning tank 3 is full of water, the endoscope and accessories are completely immersed in the water to observe whether there are bubbles. If there is a leak, there is a leak point at the place where the leak occurs.

[0039] The second step is to open the valve, drain the water in the cleaning pool 3, and use the flowing water to rinse the outer surface of the endoscope; when brushing the endoscope channel, pass one end of the endoscope through the fixing part 7 in turn, slide the slide bar 6 to straighten the endoscope; use the guide wire to guide the airbag tube 10 into the endoscope channel, the operator can hold the holding part 11, and convey the non-Newtonian fluid into the airbag tube 10 through the holding part 11. Before that, the vertical rod on one side can be rotated so that the front end of the airbag tube 10 is lower than the rear end of the airbag tube 10. The non-Newtonian fluid flows to the front end of the airbag tube 10 under the action of gravity. Under the filling of the non-Newtonian fluid, the front end of the airbag tube 10 expands, pulling the pull rope 12 connected to the deformable grid 13. The deformable grid 13 shrinks under the pulling action. Under the contraction of the deformed grid 13, the front end of the airbag tube 10 is divided; at this time, the front end of the airbag tube 10 expands and protrudes on the deformed grid 13, and a plurality of small balloons are formed on the surface of the deformed grid 13. The small balloons cooperate with the rubber protrusions to contact the side wall of the endoscope tube for brushing; in this process, by utilizing the characteristics of the non-Newtonian fluid, when the impulse of pulling the pull rope 12 is large, the non-Newtonian fluid hardens under the action of the large impulse, thereby hardening the front end of the airbag tube 10; when the impulse of pulling the pull rope 12 is small, the non-Newtonian fluid is still relatively soft under the action of the small impulse, thereby making the front end of the airbag tube 10 still relatively soft; therefore, the user can adjust the hardness of the airbag tube 10 according to the shape and structural characteristics of the part to be brushed, and perform fixed-point adaptive brushing on the endoscope tube.

[0040] After filling the front end of the airbag tube 10, the middle, lower middle, lower and other positions of the airbag tube 10 can be filled in turn by the above method, and the hardness of different positions of the airbag tube 10 can be changed by the above method.

[0041] The third step is to brush the endoscope channel in the above manner, prepare a special cleaning enzyme solution, remove the endoscope from the fixing part 7, put the cleaning enzyme solution into the cleaning tank 3, and soak the endoscope and accessories for 3 to 5 minutes; drain the enzyme solution, rinse the endoscope body and accessories in clean water, use an irrigation device to clean the endoscope channel until the enzyme solution disappears completely, use a high-pressure spray gun to blow out excess water, and dry the endoscope to avoid diluting the disinfectant; drain the clean water, fully soak the slightly dried endoscope and accessories in the disinfectant, use an irrigation device to fill the endoscope channel with disinfectant, and clean the disinfectant after 5 to 10 minutes; the operator changes the gloves, drains the disinfectant, takes out the endoscope and accessories, opens the nozzle 8 again, rinses the endoscope with running water, wipes the endoscope body, blows dry, stores it, and sets it aside.
