Description

Technical Field

[0001] The invention relates to the technical field of cleaning, and in particular to a cleaning device for digestive tract cleaning by digestive endoscopy. Background Art

[0002] With the development of modern medical technology, endoscopy has become an important means of diagnosing gastrointestinal diseases. Digestive endoscopy can directly observe the situation in the digestive tract and help medical staff diagnose diseases. However, before performing an endoscopic examination, the patient's digestive tract usually needs to be fully cleaned to ensure a clear field of vision and accurately identify the diseased area in the digestive tract. At present, commonly used methods of digestive tract cleaning include oral cleaning solution, irrigation, or local flushing through the perfusion channel of the endoscope attachment.

[0003] Although these cleaning methods can achieve certain effects in some cases, they have some problems. For example, the irrigation process is easy to be incomplete, especially in the curved or narrow parts of the digestive tract, the cleaning effect is poor, affecting the accuracy of the examination. In order to solve this problem, some digestive tract cleaning devices have been designed to improve the cleaning efficiency by adding a cleaning function during the endoscopic examination.

[0004] However, some of the existing more complete cleaning devices still have a significant technical problem, that is, the cleaning pipe is large in size and difficult to pass through narrow parts of the digestive tract. Especially during the cleaning process of small or curved parts, it is easy for the cleaning pipe to have difficulty in smoothly entering the target part, especially the water outlet part. If a large cleaning range and good effect are required, the size of the nozzle needs to be increased, which is more likely to cause difficulty in pipe insertion. If the size is to be reduced, it will affect the cleaning effect of the digestive tract. It is difficult to have both. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a digestive tract cleaning device for digestive endoscopy examination, which solves the problems of the cleaning effect and the inability to adapt the device size of the existing digestive tract cleaning device.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a digestive tract cleaning device for digestive endoscopy, comprising an integrated box and a through-tube installed on the outside of the integrated box, a water supply mechanism installed inside the integrated box, a flushing component for digestive tract cleaning connected to the free end of the through-tube, the water supply mechanism is communicated with the flushing component, an adjusting component for adjusting the size of the flushing component is installed inside the flushing component, a waste pipe for discharging is passed through and connected inside the through-tube, a terminal is fixedly installed on the outside of the free end of the waste pipe, a negative pressure mechanism is installed inside the integrated box, and a collection component that cooperates with the negative pressure mechanism to collect waste is installed on the outside of the integrated box.

[0007] Preferably, the flushing assembly includes an infusion cavity opened inside the through tube, an inflatable rubber airbag connected between the through tube and the end, and a water outlet opened in the middle of the rubber airbag, a water collecting cavity is opened inside the rubber airbag, and a water inlet pipe is installed on the outside of the integrated box for conveying flushing liquid to the infusion cavity.

[0008] Preferably, the regulating component includes an air injection tube opened inside the penetration tube, and an inner air bag separating the rubber air bag and the waste discharge pipe, the inner air bag and the waste discharge pipe form an air collecting cavity, and when air is injected into the air collecting cavity, the inner air bag expands to act on the flushing component.

[0009] Preferably, a plurality of groups of tie nets are connected between the inner airbag and the waste discharge pipe, and when the adjustment component is not working, the tie nets provide the force for the inner airbag to retract.

[0010] Preferably, a crushing plate is fixedly mounted on one end of the end head away from the through-tube, and a vibrator is installed inside the end head to drive the end head to vibrate.

[0011] Preferably, a plurality of groups of crushing fins are fixedly mounted on the inner wall of the end, and the thickness of the crushing fins is thicker and wider as they go deeper into the end.

[0012] Preferably, the collection assembly includes a box cover installed on the outside of the integrated box and a connecting pipe connected to the negative pressure mechanism. The bottom of the box cover is detachably connected to a waste collection box, and the end of the waste discharge pipe away from the end penetrates the box cover and extends to the bottom of the waste collection box.

[0013] Preferably, a camera for detection and processing and a lighting lamp for illumination are also fixedly connected to the outside of the end.

[0014] A digestive endoscopy method comprises the following steps:

[0015] S1, digestive tract cleaning, insert the unexpanded tube of the rubber balloon into a specific position inside the digestive tract, start the integrated box to transport the flushing liquid into the infusion cavity, and the flushing liquid is sprayed out from the water outlet to clean the digestive tract;

[0016] S2. Adjust the flushing water flow and inject gas into the gas injection tube. The gas enters the gas collecting cavity to expand the inner air bag and drive the rubber air bag to expand together to adapt to the digestive tract with different inner diameters.

[0017] S3, waste liquid collection, after step S2, the flushing liquid and the waste are mixed into waste liquid, at this time, the negative pressure mechanism inside the integrated box is driven to make the inside of the waste collection box in a negative pressure state, the end is aimed at the waste liquid, and the waste liquid enters the waste collection box along the waste discharge pipe;

[0018] S4, waste crushing, the vibrator drives the end head to vibrate, and the end head position is adjusted to make the crushing plate contact with the large pieces of waste, and the waste is crushed by vibration. The waste entering the middle of the end head is crushed by the crushing fins;

[0019] S5. Insert a digestive endoscope to examine the digestive tract.

[0020] Working principle: In the initial state, the rubber airbag is not inflated. It shrinks and sticks to the outside of the tube under the action of its own material and the tie net. The tube and the end are inserted from the entrance of the digestive tract. After the rubber airbag reaches the flushing location, the flushing liquid is transported to the infusion cavity through the water supply mechanism inside the integrated box. The flushing liquid enters the water collecting cavity and is sprayed out from the water outlet to flush the digestive tract. At this time, the water pressure is adjusted by changing the delivery intensity. Because the rubber airbag is not inflated in this state, the water outlet only produces a water column horizontally toward the periphery, and the flushing effect is weak. It is only suitable for narrower areas with less waste. When it reaches the large space position, gas is injected into the air injection pipe, and the gas enters the air collecting chamber from the air injection pipe and accumulates. At this time, the internal pressure of the air collecting chamber increases, which acts on the inner air bag to make the inner air bag expand. When the inner air bag expands outward, the rubber air bag expands outward synchronously under the action of water pressure. When the rubber air bag expands, the direction of the water outlet also changes, and the rubber air bag can be sprayed in all directions, which expands the spray range and improves the cleaning effect. The rubber air bag can form two states of expansion and contraction, which is convenient for entering the digestive tract while also ensuring the cleaning effect of the respiratory tract.

[0021] Secondly, after flushing is completed, the flushing liquid and waste are mixed into waste liquid. At this time, the inlet end of the end head is contacted with the waste liquid, and the negative pressure mechanism inside the integrated box is activated to form a negative pressure inside the waste collection box. At this time, the waste liquid enters the waste collection box from the waste discharge pipe for collection. During the waste liquid collection process, the vibrator can also be driven to drive the entire end head to vibrate, and the crushing plate also vibrates synchronously. When encountering larger waste in the waste liquid, the crushing plate contacts the waste and can crush the waste under the action of vibration to facilitate waste discharge. At the same time, the crushed waste will be affected by the vibration of the crushing fins when entering from the end head inlet, and will be divided into small waste again for better discharge.

[0022] The present invention provides a digestive tract cleaning device for digestive endoscopy examination. It has the following beneficial effects:

[0023] 1. The present invention uses a shrinkable and expandable rubber airbag and an inner airbag, which shrink when entering the digestive tract to reduce the outer diameter of the entire pipeline for better entry. When cleaning is required, the rubber airbag is expanded by injecting air into the air collecting cavity to increase the volume of the rubber airbag. At the same time, the expansion of the rubber airbag changes the direction of the water outlet to increase the flushing range.

[0024] 2. The present invention installs a crushing plate and crushing fins at the end position for crushing waste. When encountering large-volume waste, the crushing plate contacts the waste, and then drives the end to vibrate through the vibrator to crush the waste. The waste that has been initially crushed by the crushing plate will be crushed again by the crushing fins when entering the end, so as to further facilitate the discharge of the waste.

The free end of the through-tube 2 is connected to a flushing component for cleaning the digestive tract. The water supply mechanism is connected to the flushing component. The water supply mechanism transports the flushing liquid to the flushing component, and the digestive tract is cleaned by the flushing component. The flushing component includes an infusion cavity 5 opened inside the through-tube 2, a rubber airbag 6 connected between the through-tube 2 and the end 3 and expandable, and a water outlet 9 opened in the middle of the rubber airbag 6. A water collection cavity 8 is opened inside the rubber airbag 6. The flushing liquid can enter the water collection cavity 8 from the infusion cavity 5, and then spray out from the water outlet 9 to complete the cleaning of the digestive tract. A water inlet pipe 19 is installed outside the integrated box 1 for transporting flushing liquid to the infusion cavity 5. The outer end of the water inlet pipe 19 is connected to the external flushing liquid, and the inner end is connected to the input end of the water supply component.

[0033] Please see attached Figure 2 -Attached Figure 3 , an adjusting component for adjusting the size of the flushing component is installed inside the flushing component, the adjusting component includes an air injection tube 11 opened inside the penetration tube 2, and an inner air bag 7 dividing the rubber air bag 6 and the waste discharge pipe 4, the inner air bag 7 and the waste discharge pipe 4 form an air collecting chamber 12, when air is injected into the air collecting chamber 12, the inner air bag 7 expands to act on the flushing component, when it is necessary to clean the digestive tract with a larger space, it is necessary to first inject gas into the air injection tube 11, the gas accumulates after entering the gas collecting chamber 12, the pressure inside the gas collecting chamber 12 increases, and the inner air bag 7 is acted on, so that the inner air bag 7 expands, and when the inner air bag 7 expands outward, the rubber air bag 6 expands outward synchronously under the action of water pressure, and when the rubber air bag 6 expands, the direction of the water outlet 9 changes synchronously, and the rubber air bag 6 can be sprayed in all directions, thereby expanding the cleaning range of the digestive tract and ensuring the cleaning effect. A plurality of groups of tie nets 10 are connected between the inner air bag 7 and the waste discharge pipe 4. When the adjustment component is not working, the tie nets 10 provide the force for the inner air bag 7 to retract. Through the contraction of the tie nets 10 and the inner air bag 7 themselves, the rubber air bag 6 and the inner air bag 7 can be retracted to the outside of the through pipe 2, thereby reducing the overall volume of the cleaning pipe of the pipe to facilitate entry and discharge. At the same time, when the rubber air bag 6 and the inner air bag 7 retract, the water inside the water collection chamber 8 will also be discharged to avoid accumulation of flushing liquid.
