Description

Technical Field

[0001] The present invention belongs to the technical field of sanitary cleaning equipment, and in particular relates to a gastrointestinal tract cleaning device. Background Art

[0002] Gastrointestinal cleansing devices are primarily used to clean the lining of the gastrointestinal tract. They are suitable for preparation before endoscopic examinations and preoperative cleansing of the gastrointestinal tract. They can be used in situations such as constipation and intestinal obstruction, as well as in the treatment of poisoning or drug overdose. By injecting a cleaning fluid and combining it with negative pressure suction, the device effectively removes residual or harmful substances from the gastrointestinal tract, while ensuring a clear field of view during subsequent endoscopic examinations, potentially bringing significant socioeconomic benefits.

[0003] However, in actual use, due to individual differences in the patient's intestines, a narrow area of the intestine may be encountered, causing obstruction. This prevents the irrigation tube from passing through the obstruction and continuing to properly clean the intestine. In this case, the device can only clean the part of the intestine before the obstruction and cannot effectively clean the intestine after the obstruction, thus limiting the device's application scenarios and effectiveness.

DETAILED DESCRIPTION

[0028] like Figures 1 to 5 As shown, a gastrointestinal cleaning device includes: a main flushing tube 20, an auxiliary flushing tube 30 and a flushing driver 60, the main flushing tube 20 is provided with a first flushing chamber 21, an active chamber 22 and a lubricant storage chamber 25, the lubricant storage chamber 25 is located above the active chamber 22, and an oil outlet hole 251 is provided on the side wall of the lubricant storage chamber 25, the lubricant storage chamber 25 is connected with the active chamber 22 through the oil outlet hole 251, and a lubricating layer is provided on the side wall of the active chamber 22, the auxiliary flushing tube 30 is movably arranged in the active chamber 22, and a second flushing chamber 32 is provided in the auxiliary flushing tube 30, the output end of the flushing driver 60 is connected to the first flushing chamber 21 through a flushing water inlet pipe 40, the flushing water inlet pipe 40 is also provided with a flushing branch pipe 41, and the second flushing chamber 32 and the flushing water inlet pipe 40 are connected through the flushing branch pipe 41.

[0029] During use, the input end of the flushing driver 60 draws cleaning fluid and delivers it to the first flushing cavity 21 of the main flushing tube 20 and the second flushing cavity 32 of the auxiliary flushing tube 30 through the flushing water inlet pipe 40 and the flushing branch pipe 41, respectively. When there is no obstruction, the cleaning fluid flows out of the first flushing cavity 21 and the second flushing cavity 32, simultaneously cleaning the same area within the gastrointestinal tract. When an obstruction is encountered, the main flushing tube 20 cannot continue to penetrate into the gastrointestinal tract. By pushing the auxiliary flushing tube 30 toward the gastrointestinal tract, the outer surface of the auxiliary flushing tube 30 contacts the lubricating layer on the side wall of the active cavity 22, allowing the auxiliary flushing tube 30 to slide smoothly within the active cavity 22. The medical silicone oil in the lubricant storage cavity 25 can be discharged to the outer surface of the auxiliary flushing tube 30 through the oil outlet 251, ensuring that the movement of the auxiliary flushing tube 30 is always smooth, thereby smoothly bypassing the obstruction and continuing to extend into the gastrointestinal tract, allowing the auxiliary flushing tube 30 to clean areas within the gastrointestinal tract that the main flushing tube 20 cannot clean. Through the above-mentioned arrangement, the reliability, flexibility and adaptability of the gastrointestinal cleaning device during cleaning are increased, and the blind spots in cleaning are reduced. At the same time, it can also cope with complex situations in the gastrointestinal tract and ensure the continuity and effectiveness of the cleaning process. It should be noted that the flushing driver 60 is a peristaltic pump, which squeezes the hose through a rotating roller or a pressure block, causing the liquid in the hose to flow forward. The squeezing action of the peristaltic pump is relatively gentle, which prevents the cleaning liquid flowing out of the first flushing cavity 21 and the second flushing cavity 32 from causing excessive impact force and damaging the gastrointestinal tract. The above-mentioned lubricating layer is a medical silicone oil lubricating layer. Medical silicone oil is mild in nature and will not react with the liquid or tissue in the gastrointestinal tract, and will not irritate the patient's gastrointestinal tract.

[0030] Preferably, Figure 5 and Figure 7 As shown, the main flushing tube 20 further defines an oil replenishment chamber 26, which extends through one end of the main flushing tube 20. A block 27 is provided within the oil replenishment chamber 26 to seal the oil replenishment chamber 26. The block 27 defines an oil injection hole 271 that communicates with the lubricant storage chamber 25. If the secondary flushing tube 30 becomes stuck while being pushed within the movable chamber 22, medical personnel can use a syringe to inject medical silicone oil into the lubricant storage chamber 25 through the oil injection hole 271 to replenish the lubricant storage chamber 25. The block 27 also isolates the silicone oil from the outside world, preventing external dust from entering the lubricant storage chamber 25 and contaminating the medical silicone oil.

[0031] Preferably, Figure 5 and Figure 7As shown, the gastrointestinal tract cleaning device also includes: an inflation driver and an inflation ring 80, the inflation ring 80 being connected to the inflation driver via an air tube; a bearing 24 being installed in the movable chamber 22, the outer surface of the inflation ring 80 abutting against the inner surface of the bearing 24, and the secondary flushing tube 30 being sleeved on the inner surface of the inflation ring 80. Specifically, the surface of the main flushing tube 20 further defines an installation cavity 29, which is in communication with the movable chamber 22 and has a diameter greater than that of the movable chamber 22. The bearing 24 is disposed in the installation cavity 29, and the outer surface of the bearing 24 is connected to the side wall of the installation cavity 29. To enhance the gastrointestinal cleansing effectiveness of the auxiliary flushing tube 30, an inflatable ring 80 is inflated using an inflatable driver. When the inflatable ring 80 expands, its inner surface clamps the auxiliary flushing tube 30, forming a secure connection between the auxiliary flushing tube 30, the inflatable ring 80, and the shaft. When the auxiliary flushing tube 30 is rotated, the bearing 24 rotates with the pipe, thereby changing the flushing angle of the auxiliary flushing tube 30 and achieving a better flushing effect. The bearing 24 reduces resistance during rotation of the auxiliary flushing tube 30, allowing it to rotate smoothly.

[0032] Preferably, Figure 2-Figure 4 As shown, the gastrointestinal tract cleaning device further includes: a liquid pumping driver 61 and a liquid storage tank 10. The liquid storage tank 10 defines a liquid storage chamber 12 and a collection chamber 11. The main flushing pipe 20 further defines a first liquid pumping chamber 23, and the auxiliary flushing pipe 30 further defines a second liquid pumping chamber 31. The input end of the liquid pumping driver 61 is connected to the first liquid pumping chamber 23 via a liquid pumping drainage pipe 50. The liquid pumping drainage pipe 50 is also provided with a liquid pumping branch pipe 51. The second liquid pumping chamber 31 is connected to the liquid pumping drainage pipe 50 via the liquid pumping branch pipe 51. The input end of the flushing driver 60 is connected to the liquid storage chamber 12 via a liquid suction pipe 70, and the output end of the liquid pumping driver 61 is connected to the collection chamber 11 via a liquid discharge pipe 71. The flushing driver 60, in conjunction with the flushing water inlet pipe 40 and the flushing branch pipe 41, can transport the cleaning liquid in the liquid storage chamber to the first flushing chamber 21 and the second flushing chamber 32. The cleaning liquid then flows out of the first flushing chamber 21 and the second flushing chamber 32 to clean the gastrointestinal tract. The liquid extraction driver 61 cooperates with the liquid extraction drainage pipe 50 and the liquid extraction branch pipe 51 to extract the waste liquid after cleaning through the second liquid extraction chamber 31 and the first liquid extraction chamber 23, and then discharges the waste liquid into the collection chamber 11 through the output end of the liquid extraction driver 61. The cycle is repeated to complete the cleaning of the gastrointestinal tract.

[0033] Preferably, Figure 2-Figure 4As shown, the gastrointestinal cleaning device also includes: a drug delivery driver 62, a drug liquid chamber 13 is further provided in the liquid storage tank 10, a first drug delivery chamber 28 is further provided in the main flushing pipe 20, and a second drug delivery chamber 33 is provided in the auxiliary flushing pipe 30. The output end of the drug delivery driver 62 is connected to the first drug delivery chamber 28 through a drug delivery water inlet pipe 53, and a drug delivery branch pipe 54 is further provided on the drug delivery water inlet pipe 53. The second drug delivery chamber 33 is connected to the drug delivery water inlet pipe 53 through the drug delivery branch pipe 54. The input end of the drug delivery driver 62 is connected to the drug liquid chamber 13 through a liquid suction pipe 72. When cleaning the intestine, it is usually necessary to use it with drugs to enhance the cleaning effect of the gastrointestinal tract. For example, in the case of drug poisoning or gastrointestinal infection or inflammation, the drug delivery driver, in conjunction with the drug delivery water inlet pipe 53 and the drug delivery branch pipe 54, can deliver the drug liquid in the drug liquid chamber 13 into the first drug delivery chamber 28 and the second drug delivery chamber 33 and then discharge it into the gastrointestinal tract, thereby adjusting and assisting the cleaning of the gastrointestinal tract. It should be noted that the drug delivery driver 62 is a peristaltic pump.

[0034] Preferably, Figure 6 、 Figure 8 and Figure 9 As shown, in one embodiment, the gastrointestinal tract cleaning device further includes a mounting block 90, wherein a mounting hole 34 is defined in the flushing branch tube 41, and an internal thread 341 is defined on the sidewall of the mounting hole 34. The outer surface of the mounting block 90 is provided with an external thread 91, and the internal thread 341 is threadedly connected to the external thread 91. The mounting block 90 defines a mounting cavity 93, within which an illumination fiber 99, a camera 97, and a power supply module 98 are disposed. The camera 97 and the illumination fiber 99 are both electrically connected to the power supply module 98. The mounting block 90 is made of medical rubber to reduce irritation to the intestine when the secondary flushing tube 30 enters the intestine. The gastrointestinal tract cleaning device further includes a device housing 1, within which a control module and a display screen 2 are disposed. The control module is electrically connected to the power supply module 98 and the display screen 2. During use, the illumination fiber 99 illuminates the interior of the gastrointestinal tract, the camera 97 captures real-time images of the gastrointestinal tract, and the display screen 2 can display the images captured by the camera 97 in real time, allowing medical personnel to adjust cleaning strategies based on the conditions within the gastrointestinal tract. By providing the internal thread 341 and the external thread 91, the camera 97 in the placement block 90 can be conveniently installed in the auxiliary flushing pipe 30. It should be noted that displaying the image captured by the camera 97 through the control module in conjunction with the display screen 2 is a common method used by those skilled in the art, so its implementation principle and structure are not described in detail.

[0035] Preferably, Figure 8 and Figure 9As shown, a sealing ring 92 is provided within the placement cavity 93. An illumination fiber 99, a camera 97, and a power supply module 98 are all disposed between the sealing ring 92 and the inner wall of the placement cavity 93. The sealing ring 92 is a transparent structure. The sealing ring 92 prevents fluid from the gastrointestinal tract from entering the placement cavity 93, thereby preventing the fluid from the gastrointestinal tract from damaging the camera 97, illumination fiber 99, and power supply module 98 within the placement cavity 93.

[0036] Preferably, the diameters of the first pumping chamber 23 and the second pumping chamber 31 gradually decrease from one end to the middle thereof, and gradually increase from the middle to the other end thereof. The above arrangement allows the channels within the first pumping chamber 23 and the second pumping chamber 31 to first change from large to small and then from small to large, thereby forming a narrow channel in the middle of the first pumping chamber 23 and the second pumping chamber 31. When waste liquid flows from a large-diameter channel to a small-diameter area, the flow rate increases and the pressure decreases. When the waste liquid flows from the narrow middle area to the wider end, the flow rate slows down and the pressure increases, thereby increasing the suction force of the first pumping chamber 23 and the second pumping chamber 31, thereby improving the effect of sucking out waste liquid.

[0037] Preferably, Figure 3 and Figure 4 As shown, the gastrointestinal tract cleaning device further includes a backflush tube 63, the output end of which is connected to the flushing water inlet pipe 40, and the input end of which is connected to the side wall of the second liquid extraction chamber 31. When the liquid extraction driver 61 cooperates with the second liquid extraction chamber 31 to extract waste liquid, and solid impurities in the waste liquid clog the second liquid extraction chamber 31, the liquid extraction driver 61 is shut down, and water is pumped into the second liquid extraction chamber 31 via the backflush tube 63, thereby flushing the solid impurities in the waste liquid out of the second liquid extraction chamber 31. The liquid extraction driver 61 is then restarted to continue extracting waste liquid, ensuring a stable extraction process.

[0038] Preferably, the gastrointestinal tract cleaning device further comprises: a two-way valve and a connecting tube, wherein the output end of the two-way valve is connected to the input end of the backflushing tube 63, one end of the connecting tube is connected to the output end of the two-way valve, and the other end of the connecting tube is connected to the side wall of the second liquid extraction chamber 31. The two-way valve is a two-position two-way solenoid valve, which can control the flow of the connecting tube, thereby flexibly controlling the opening and closing of the connecting tube according to whether the second liquid extraction chamber 31 needs to be backflushed, thereby avoiding interference with the liquid extraction driver 61 cooperating with the second liquid extraction chamber 31 to extract waste liquid.

[0039] It should be noted that the first end of the main flushing tube 20 is fixedly mounted within the device housing 1, and the second end of the auxiliary flushing tube 30 passes through the first end of the main flushing tube 20 and exits the second end of the main flushing tube 20. The first end of the auxiliary flushing tube 30 is spaced a distance from the first end of the main flushing tube 20, thereby providing space for the auxiliary flushing tube 30 to move within the mounting cavity 29. The main flushing tube 20 and the auxiliary flushing tube 30 are coiled within the device housing 1. When used by medical personnel, they can pull the second end of the main flushing tube 20 to pull the main flushing tube 20 and the auxiliary flushing tube 30 out of the device housing 1. This allows main flushing tubes 20 and auxiliary flushing tubes 30 of different lengths to be used for cleaning the gastrointestinal tract, and then whether to push the first end of the auxiliary flushing tube 30 is determined based on whether obstruction is encountered. It can be seen that the cleaning device of the present application has components such as liquid delivery and flushing, and is flexible and reliable in operation, with high controllability and cleaning efficiency.

[0040] It should be noted that after completing the cleaning of the gastrointestinal tract and removing the main flushing tube 20 from the patient's body, the placement block 90 is first removed from the auxiliary flushing tube 30 and cleaned separately, and then the auxiliary flushing tube 30, the flushing water inlet pipe 40, the flushing branch pipe 41, the liquid extraction and drainage pipe 50, the liquid extraction branch pipe 51, the drug administration water inlet pipe 53, the drug administration branch pipe 54, the backflush pipe 63, the liquid suction tube 70, the liquid discharge pipe 71 and the liquid suction drug tube 72 are disassembled and cleaned and disinfected before being put into use again.
