Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to a gastric lavage device. Background Art

[0002] Gastric lavage is an important rescue measure in which a gastric lavage tube is connected to the patient in a side-lying position, and a gastric lavage fluid of a certain composition is poured into the stomach cavity, mixed with the stomach contents, and then drawn out. This is repeated many times to remove unabsorbed toxins in the stomach or clean the stomach cavity. During the operation, a gastric tube is inserted from the nasal cavity or oral cavity, through the esophagus to the stomach, and the toxins are first sucked out and then the gastric lavage fluid is injected, and the stomach contents are discharged to achieve the purpose of eliminating the toxins. During nursing, care should be taken to avoid gastric tube contamination and gastric tube prolapse. The existing gastric lavage equipment is inserted into the patient's stomach during actual use. A gastric tube continuously introduces gastric lavage fluid into the patient's stomach. The gastric lavage fluid and the patient's stomach contents need to be fully mixed before extraction. This process needs to be repeated many times until the extracted liquid has a high degree of clarity. During this process, since the patient is always in a lateral decubitus position and does not move, the gastric lavage fluid entering the stomach and the stomach contents are not mixed enough each time, so the process is repeated many times, which makes the patient feel uncomfortable and causes reflux, vomiting, drooling, etc. Therefore, it is necessary to provide a gastric lavage device that can fully mix and improve the comfort of the patient during the gastric lavage process. Summary of the invention

[0003] The present invention is intended to provide a gastric lavage device, so as to provide a gastric lavage device which can mix sufficiently and improve the comfort of the patient during the gastric lavage process.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a gastric lavage device, comprising a gastric lavage device and a gastric tube connected to the gastric lavage device, a mixing unit is provided at the end of the gastric tube, the mixing unit comprises a connecting tube, a rotating part and a one-way part, the connecting tube is fixedly connected to the gastric tube, the rotating part is annular and comprises an outer ring and an inner ring, the outer ring of the rotating part is rotatably connected to the end of the connecting tube, a fan blade part is rotatably provided between the inner ring and the outer ring of the rotating part, the fan blade part rotates when the fluid passes through the fan blade part, the one-way part is fixed in the inner ring of the rotating part, the one-way part is opened when the mixture is inhaled, and is closed when the gastric lavage fluid is output.

[0005] The beneficial effects of this program are:

[0006] Through the above arrangement, when the gastric lavage device introduces gastric lavage fluid into the gastric tube, the one-way portion is in a closed state, and the fluid can only enter the patient's stomach through the fan blade portion arranged at the end of the connecting tube. When the fluid passes through the fan blade portion, the fan blade portion rotates, and the rotation of the fan blade portion drives the outflowing fluid to rotate. When the one-way portion is closed, the cross-sectional area through which the fluid can flow is reduced, and the flow rate is increased, so that the gastric lavage fluid entering the patient's stomach has a certain flushing force. At the same time, driven by the rotation of the fan blade portion, the gastric lavage fluid can be fully mixed with the contents of the patient's stomach, greatly increasing the contact area between the gastric lavage fluid and the gastric contents, promoting the full mixing of the liquid and the contents in the stomach, and at the same time being able to flush the stomach wall, thereby improving the efficiency of gastric lavage, avoiding multiple repeated operations due to insufficient liquid mixing in traditional gastric lavage methods, and reducing gastric lavage time, thereby achieving an all-round cleaning effect. If the flow rate of the gastric lavage solution is simply increased to flush the stomach wall, the patient may feel uncomfortable and vomit during the cleaning process. The present technical solution can achieve sufficient mixing while not significantly increasing the flushing pressure, making the patient feel more comfortable. When the mixture in the patient's stomach is extracted, the one-way portion is opened. On the one hand, there is some solid mixture in the stomach during extraction, and the one-way portion opening alone can help extract the above mixture. On the other hand, the cross-sectional area through which the fluid can pass during extraction is larger, which also helps to improve the efficiency of extraction. After extraction to a certain extent, the step of introducing gastric lavage solution into the stomach tube is repeated.

[0007] This technical solution reduces the number of repeated operations by optimizing the mixing and extraction process of gastric lavage fluid and gastric contents, thereby alleviating the discomfort of patients during gastric lavage and avoiding the physiological phenomena of nausea, vomiting, etc. in patients that are easily caused by multiple and repeated injections and extractions in traditional gastric lavage methods. The fan blades, rotating parts, and one-way parts in this technical solution are simple in design and operate automatically during the injection and extraction process, reducing the complexity of operations for medical staff and improving the ease of use of the device.

[0008] Preferably, as an improvement, it further comprises an air bag portion, which comprises an annular air bag and a trachea connected to the air bag, and the air bag is fixed to the inner wall of the connection part between the connecting tube and the stomach tube.

[0009] The beneficial effect is that when the gastric lavage fluid is pushed forward, the gastric lavage fluid injected into the stomach is further pressurized by filling the air bag with gas, thereby increasing the flow rate of the gastric lavage fluid in the gastric tube, so that the liquid reaches the patient's stomach in a shorter time, thereby speeding up the entire gastric lavage process.

[0010] Preferably, as an improvement, the one-way portion includes a fixed ring and a plurality of blades, the blades are evenly distributed circumferentially on one side of the fixed ring close to the gastric tube, the blades are rotatably connected to the fixed ring via a hinge, the fixed ring is fixedly connected to the inner ring of the rotating portion, the blades close when gastric lavage fluid is injected, and the blades open when the fluid flows in the opposite direction.

[0011] The beneficial effects are: during the injection of gastric lavage fluid, the blades will close so that the gastric lavage fluid enters the patient's stomach through the fan blade part. When the mixture in the stomach needs to be extracted, the reverse flow of the fluid will push the blades open, causing them to open automatically, thereby increasing the fluid channel area, allowing the mixture in the stomach to flow out quickly and smoothly, making the device more suitable for frequent fluid exchange processes and reducing the number of operations.

[0012] Preferably, as an improvement, the fan blade portion includes a rotating shaft and a plurality of fan blades circumferentially distributed on the rotating shaft, the fan blades are all tilted and fixed on the rotating shaft, and the rotating shaft is rotatably sleeved on the inner ring.

[0013] Preferably, as an improvement, the rotating part further includes a connecting strip, the outer ring and the inner ring are connected by the connecting strip, and the inner side wall of the outer ring of the rotating part cross section is conical.

[0014] The beneficial effects are as follows: the inner wall of the outer ring is conical, so that the gastric lavage fluid entering the stomach is guided along the conical inner wall, thereby achieving outward dispersion of the fluid so that the gastric lavage fluid can flow evenly around the stomach wall instead of concentrating in a certain place in the stomach cavity, reducing local impact and cleaning the stomach cavity more effectively, thereby better diluting and flushing the residues in the stomach and improving the efficiency of gastric lavage.

[0015] Preferably, as an improvement, the gastric lavage device includes a medicine liquid unit, a propulsion part and a collecting unit, the medicine liquid unit includes a medicine liquid propulsion barrel and a medicine liquid configuration box connected to the medicine liquid propulsion barrel, the medicine liquid propulsion barrel and the collecting propulsion barrel are both connected to the gastric tube, the collecting unit includes a collecting propulsion barrel and a collecting box connected to the collecting propulsion barrel, a medicine liquid push rod is provided in the sliding seal in the medicine liquid propulsion barrel, a collecting push rod is provided in the sliding seal in the collecting propulsion barrel, a screw part is provided between the medicine liquid push rod and the collecting push rod, the screw part includes a screw, a slider slidably connected to the screw and a guide rod for guiding the slider, a clamping disk is fixed to the end of the medicine liquid push rod and the collecting push rod, a clamping groove is provided on one side of the clamping disk, electric latches are provided on both sides of the slider, and the electric latch can be telescopically inserted into a corresponding clamping groove.

[0016] The beneficial effect is as follows: through the above arrangement, when the gastric lavage liquid is first used, the liquid medicine push barrel is filled with gastric lavage liquid, an electric latch on the slider is extended and inserted into the clamping groove on the liquid medicine push rod, the screw rod rotates to drive the slider to slide, and drives the liquid medicine push rod to push and inject the gastric lavage liquid into the patient's body; when the gastric lavage liquid injected reaches the set value, the collection push barrel should be empty at this time, the electric latch is retracted, and another electric latch is started to be inserted into the clamping groove of the collection push rod, and the screw rod rotates in the opposite direction to extract the gastric mixture after the reaction. Through the above arrangement, on the one hand, by controlling the rotation of the screw rod, it is possible to achieve precise control of the injection of gastric lavage liquid and the extraction amount of gastric contents by adjusting the rotation distance of the screw rod, and at the same time, the injection and extraction pressures can be adjusted by adjusting the rotation speed of the screw rod. On the other hand, the gastric mixture and the gastric lavage liquid are placed separately and do not share a barrel, which can avoid the gastric mixture from being re-injected into the stomach, resulting in an increase in the number of repeated cleanings, shortening the time of the entire gastric lavage process, reducing the pain of the patient, and improving the efficiency and hygiene of the gastric lavage process.

[0017] Preferably, as an improvement, it also includes multiple check valves and solenoid valves, the ends of the medicine liquid propulsion barrel and the collection propulsion barrel are connected to the first connecting tube through the solenoid valve, the first connecting tube is provided with a check valve, the flow directions of the two check valves are opposite, and the ends of the two first connecting tubes are connected to one end of the gastric tube through a three-way joint.

[0018] The beneficial effects are as follows: the ends of the medicine liquid propulsion barrel and the collection propulsion barrel are respectively provided with check valves with opposite flow directions, thereby ensuring that the medicine liquid propulsion barrel is only used to inject gastric lavage fluid into the stomach, and the collection propulsion barrel is only used to extract gastric contents, effectively preventing the liquid from flowing back during operation, avoiding the cross flow of medicine liquid or gastric contents, and improving the safety of the gastric lavage process.

[0020] The beneficial effects are as follows: through the above arrangement, when the collection push rod slides to extract the mixture, the solenoid valve on one side of the liquid medicine push barrel is closed, and the pumping pump pushes the gastric lavage solution into the liquid medicine push barrel in one direction for the next injection, so that the liquid medicine push rod returns to the initial position, and when the gastric lavage solution is injected, the contents in the collection push barrel are discharged; when the liquid medicine push barrel completes one gastric lavage solution injection, the pumping pump automatically replenishes the liquid medicine in the liquid medicine configuration box to the liquid medicine push barrel, ensuring that the next gastric lavage does not require manual re-addition of liquid medicine, shortening the gastric lavage preparation time, and the liquid medicine can be continuously supplied without interrupting the operation, which helps to achieve the continuity of the gastric lavage process.

[0025] The figure marks in the drawings of the specification include: gastric tube 1, connecting tube 2, outer ring 3, inner ring 4, rotating shaft 5, fan blade 6, connecting strip 7, blade 8, fixing ring 9, hinge 10, air bag 11, trachea 12, medicine liquid propulsion barrel 13, medicine liquid configuration box 14, collection propulsion barrel 15, collection box 16, medicine liquid push rod 17, collection push rod 18, screw 19, slider 20, clamping plate 21, stirring rod 22, clamping groove 23, electric latch 24, check valve 25, solenoid valve 26, first connecting pipe 27, second connecting pipe 28, pumping pump 29, bevel ring 30.

[0026] Example 1

[0027] Example 1 is basically as Figure 1-Figure 3 As shown, Figure 1A gastric lavage device shown includes a gastric lavage device and a gastric tube 1 connected to the gastric lavage device. A mixing unit is provided at the end of the gastric tube 1. The mixing unit includes a connecting tube 2, a rotating part and a one-way part. The connecting tube 2 is fixedly connected to the gastric tube 1. The rotating part is annular and includes an outer ring 3 and an inner ring 4. The outer ring 3 of the rotating part is rotatably connected to the end of the connecting tube 2. A fan blade 6 is rotatably provided between the inner ring 4 and the outer ring 3 of the rotating part. In this embodiment, the fan blade 6 includes a rotating shaft 5 and a plurality of fan blades 6 circumferentially distributed on the rotating shaft 5. The fan blades 6 are all obliquely fixed on the rotating shaft 5. The rotating shaft 5 is rotatably sleeved on the inner ring 4. The rotating part also includes a connecting strip 7. The outer ring 3 and the inner ring 4 are connected by the connecting strip 7. The inner side wall of the outer ring 3 of the rotating part cross section is conical. The inner wall of the outer ring 3 is conical, so that the gastric lavage fluid entering the stomach is guided along the conical inner wall, thereby achieving outward dispersion of the fluid so that the gastric lavage fluid can flow evenly around the stomach wall instead of concentrating in a certain place in the stomach cavity, reducing local impact and cleaning the stomach cavity more effectively, thereby better diluting and flushing the residue in the stomach and improving the efficiency of gastric lavage.

[0028] like Figure 2 As shown, the one-way portion includes a fixed ring 9 and a plurality of blades 8. A bevel ring 30 is also fixed to the inner side of the inner ring 4. The bevel ring 30 is provided so that the blades 8 will not be flipped to be perpendicular to the bottom surface when flipped upward. In this way, when the fluid flows from top to bottom, there is an oblique component force that pushes the blades 8 to cover the fixed ring 9. The blades 8 are circumferentially evenly distributed on the side of the fixed ring 9 close to the gastric tube 1. The blades 8 are rotatably connected to the fixed ring 9 through a hinge 10. The fixed ring 9 is fixedly connected to the inner ring 4 of the rotating portion. When the gastric lavage fluid is injected, the blades 8 are closed, and the blades 8 are opened when the fluid flows in the reverse direction. During the injection of the gastric lavage fluid, the blades 8 will close so that the gastric lavage fluid enters the patient's stomach through the fan blades 6. When the gastric mixture needs to be extracted, the reverse flow of the fluid will push the blades 8 away, causing them to open automatically, thereby increasing the channel area of ​​the fluid, so that the gastric mixture can flow out quickly and smoothly. Through the above-mentioned arrangement, when the fluid passes through the fan blades 6, the fan blades 6 rotate, and the one-way part is fixed in the inner ring 4 of the rotating part. The one-way part is opened when the mixture is inhaled and closed when the gastric lavage fluid is output; when the gastric lavage device introduces gastric lavage fluid into the gastric tube 1, the one-way part is in a closed state, and the fluid can only enter the patient's stomach through the fan blades 6 arranged at the end of the connecting tube 2. When the fluid passes through the fan blades 6, the fan blades 6 rotate, and the rotation of the fan blades 6 drives the outflowing fluid to rotate. When the one-way part is closed, the cross-sectional area through which the fluid can flow is reduced, and the flow rate is increased, so that the gastric lavage fluid entering the patient's stomach has a certain flushing force. At the same time, driven by the rotation of the fan blades 6, the gastric lavage fluid can be fully mixed with the contents of the patient's stomach, greatly increasing the contact area between the gastric lavage fluid and the gastric contents, promoting the full mixing of the liquid and the contents in the stomach, and at the same time being able to flush the stomach wall, thereby improving the efficiency of gastric lavage.

[0029] The device further comprises an airbag 11, which comprises an annular airbag 11 and a trachea 12 connected to the airbag 11, and the airbag 11 is fixed to the inner wall of the connection between the connecting tube 2 and the gastric tube 1; when the gastric lavage fluid is pushed forward, the gastric lavage fluid injected into the stomach is further pressurized by filling the airbag 11 with gas, thereby increasing the flow rate of the gastric lavage fluid in the gastric tube 1, so that the liquid reaches the patient's stomach in a shorter time, thereby speeding up the entire gastric lavage process.

[0030] like Figure 3 As shown, the gastric lavage device includes a liquid medicine unit, a propulsion unit and a collection unit. The liquid medicine unit includes a liquid medicine propulsion barrel 13 and a liquid medicine configuration box 14 connected to the liquid medicine propulsion barrel 13. The liquid medicine propulsion barrel 13 and the collection propulsion barrel 15 are both connected to the stomach tube 1. The collection unit includes the collection propulsion barrel 15 and a collection box 16 connected to the collection propulsion barrel 15. A liquid medicine push rod 17 is provided in the liquid medicine propulsion barrel 13 for sliding sealing. A collection push rod 18 is provided in the collection propulsion barrel 15 for sliding sealing. A screw rod 19 is provided between the liquid medicine push rod 17 and the collection push rod 18. The screw rod 19 is provided between the liquid medicine push rod 17 and the collection push rod 18. Part 19 includes a screw rod 19, a slider 20 slidably connected to the screw rod 19, and a guide rod for guiding the slider 20. The ends of the liquid medicine push rod 17 and the collection push rod 18 are fixed with a clamping disk 21, and a clamping groove 23 is opened on one side of the clamping disk 21. Electric latches 24 are provided on both sides of the slider 20, and the electric latches 24 can be telescopically inserted into a corresponding clamping groove 23. In this embodiment, a shell is provided on the outside of the liquid medicine propulsion barrel 13 and the collection propulsion barrel 15. The two ends of the screw rod 19 are rotatably connected to the shell, and a motor is provided inside the shell to drive the screw rod 19 to rotate. Through the above arrangement, when the use starts, the liquid medicine push barrel 13 is filled with gastric lavage liquid, an electric plug 24 on the slider 20 is extended and inserted into the clamping groove 23 on the liquid medicine push rod 17, and the screw rod 19 rotates to drive the slider 20 to slide, and drives the liquid medicine push rod 17 to push and inject the gastric lavage liquid into the patient's body; when the gastric lavage liquid reaches the set value, the collection push barrel 15 should be empty at this time, the electric plug 24 is retracted, and another electric plug 24 is started to be inserted into the clamping groove 23 of the collection push rod 18, and the screw rod 19 rotates in the opposite direction to extract the gastric mixture after the reaction. Through the above arrangement On the one hand, by controlling the rotation of the screw rod 19, the injection of the gastric lavage solution and the amount of gastric contents extracted can be accurately controlled by adjusting the rotation distance of the screw rod 19. At the same time, the injection and extraction pressures can be adjusted by adjusting the rotation speed of the screw rod 19. On the other hand, the gastric mixture and the gastric lavage solution are placed separately and do not share the same bucket, which can avoid the gastric mixture from being re-injected into the stomach, resulting in an increase in the number of repeated cleanings, shortening the time of the entire gastric lavage process, reducing the patient's pain, and improving the efficiency and hygiene of the gastric lavage process.

[0031] It also includes multiple check valves 25 and solenoid valves 26. The ends of the medicine liquid propulsion barrel 13 and the collection propulsion barrel 15 are connected to the first connecting pipe 27 through the solenoid valve 26. The first connecting pipe 27 is provided with a check valve 25. The flow directions of the two check valves 25 are opposite. The ends of the two first connecting pipes 27 are connected to one end of the gastric tube 1 through a three-way joint. The ends of the medicine liquid propulsion barrel 13 and the collection propulsion barrel 15 are respectively equipped with check valves 25 with opposite flow directions, thereby ensuring that the medicine liquid propulsion barrel 13 is only used to inject gastric lavage liquid into the stomach, and the collection propulsion barrel 15 is only used to extract gastric contents, effectively preventing the liquid from flowing back during operation, avoiding the cross flow of medicine or gastric contents, and improving the safety of the gastric lavage process.

[0032] The liquid medicine configuration box 14 is provided with a stirring rod 22, and a feeding port and a liquid injection port are provided on the upper surface of the liquid medicine configuration box 14. Through the above arrangement, when the collecting push rod 18 slides and extracts the mixture, the liquid medicine configuration box 14 is provided with a stirring rod 22, and a feeding port and a liquid injection port are provided on the upper surface of the liquid medicine configuration box 14. The electromagnetic valve 26 on one side of the liquid propulsion barrel 13 is closed, and the pumping pump 29 pushes the gastric lavage liquid into the liquid propulsion barrel 13 in one direction for the next injection, so that the liquid push rod 17 returns to the initial position. When the gastric lavage liquid is injected, the contents in the collection propulsion barrel 15 are discharged; when the liquid propulsion barrel 13 completes a gastric lavage liquid injection, the pumping pump 29 automatically replenishes the liquid in the liquid configuration box 14 to the liquid propulsion barrel 13, ensuring that the next gastric lavage does not require manual re-addition of liquid, shortening the gastric lavage preparation time, and the liquid can be continuously supplied without interrupting the operation, which helps to achieve the continuity of the gastric lavage process. A stirring rod 22 is set in the liquid configuration box 14, which helps to evenly mix the liquid components, ensure that the concentration of the gastric lavage liquid injected each time is consistent, improve the effect of the gastric lavage liquid, and enable the liquid to be quickly and evenly configured as needed, avoiding the effect of gastric lavage affected by uneven liquid concentration.

[0033] The specific implementation process is as follows:

[0034] Through the above arrangement, when the gastric lavage device introduces gastric lavage fluid into the gastric tube 1, the one-way portion is in a closed state, and the fluid can only enter the patient's stomach through the fan blades 6 arranged at the end of the connecting tube 2. When the fluid passes through the fan blades 6, the fan blades 6 rotate, and the rotation of the fan blades 6 drives the outflowing fluid to rotate. When the one-way portion is closed, the cross-sectional area through which the fluid can flow is reduced, and the flow rate is increased, so that the gastric lavage fluid entering the patient's stomach has a certain flushing force. At the same time, driven by the rotation of the fan blades 6, the gastric lavage fluid can be fully mixed with the contents of the patient's stomach, greatly increasing the contact area between the gastric lavage fluid and the gastric contents, promoting the full mixing of the liquid and the contents in the stomach, and at the same time being able to flush the stomach wall, thereby improving the efficiency of gastric lavage, avoiding multiple repeated operations due to insufficient liquid mixing in traditional gastric lavage methods, and reducing gastric lavage time, thereby achieving an all-round cleaning effect. If the flow rate of the gastric lavage solution is simply increased to flush the stomach wall, the patient may feel uncomfortable and vomit during the cleaning process. The present technical solution can achieve sufficient mixing while not significantly increasing the flushing pressure, making the patient feel more comfortable. When the mixture in the patient's stomach is extracted, the one-way portion is opened. On the one hand, there is some solid mixture in the stomach during extraction, and the one-way portion opening alone can help extract the above mixture. On the other hand, the cross-sectional area through which the fluid can pass during extraction is larger, which also helps to improve the efficiency of extraction. When extraction reaches a certain level, the step of introducing gastric lavage solution into the stomach tube 1 is repeated.

[0035] The technical solution reduces the number of repeated operations by optimizing the mixing and extraction process of the gastric lavage solution and the gastric contents, thereby reducing the discomfort of the patient during the gastric lavage process and avoiding the physiological phenomena of nausea, vomiting, etc. in the traditional gastric lavage method, which are easily caused by multiple and repeated injections and extractions. The fan blade 6, the rotating part and the one-way part in the technical solution are simple in design and automatically operate during the injection and extraction process, which reduces the complexity of the operation of medical staff and improves the ease of use of the device.

[0036] Example 2

[0037] The difference between Example 2 and Example 1 is that a sliding flat clamp is fixedly connected to one side of the slider 20. The trachea 12 in this embodiment is a hose, and the sliding flat clamp is slidably sleeved on the rear end of the trachea 12. When the gastric lavage solution is injected, the slider 20 drives the sliding flat clamp to slide along the trachea 12, pushing the gas in the trachea 12 into the airbag 11. When the slider 20 slides in the opposite direction, the gas in the airbag 11 returns to the trachea 12. Through the above arrangement, when the gastric lavage solution is injected, the airbag 11 gradually inflates and slowly increases the pressure to flush the contents in the stomach. When the contents are extracted, the gas in the airbag 11 flows out to slow down the extraction speed, further improving the patient's comfort during the extraction process.

[0038] Example 3

[0039] The difference between Example 3 and Example 1 is that the other end of the trachea 12 is connected to an air pump. When the gastric lavage process is completed, gas is introduced into the airbag 11 through the air pump, so that the airbag 11 is inflated to seal the end of the gastric tube 1, and the stomach environment and the gastric tube 1 are isolated. At this time, when the collection push rod 18 is pulled, the residual liquid in the gastric tube 1 can be sucked out without sucking out all the remaining liquid in the stomach, causing stomach discomfort to the patient. At this time, the gastric tube 1 will become deflated, which is convenient for medical staff to take out the gastric tube, and the patient's rejection reaction will be smaller; at the same time, the end of the gastric tube will undergo a certain deformation after the airbag 11 is inflated. When taking out the gastric tube 1, the operator can judge to what position the gastric tube 1 slides by the smoothness of the sliding of the end of the gastric tube 1 in the esophagus, thereby achieving better control of the operation process.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
