[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment: As Figures 1 - 6 shown, the present invention provides a technical solution for an enema administration device for treating colitis, which is characterized in that: the enema administration device for treating colitis includes a working box 1, a medicine administration cylinder 2 is installed in the working box 1, an outlet baffle 3 and an inlet baffle 4 are respectively installed at both ends of the medicine administration cylinder 2, a push plate 5 is slidably installed between the inlet baffle 4 and the outlet baffle 3, a screw rod 6 is installed at one end of the push plate 5 close to the inlet baffle 4, the screw rod 6 penetrates through the inlet baffle 4, a servo motor 11 and a gear mounting plate 10 are installed in the working box 1, a driving gear 12 is installed on the output shaft of the servo motor 11, a driven gear 13 is rotatably installed on the gear mounting plate 10, the driven gear 13 meshes with the driving gear 12, the driven gear 13 is in threaded cooperation with the screw rod 6, a medicine administration hole 7 is opened on the outlet baffle 3, a medicine administration tube 8 is installed on the medicine administration hole 7, the medicine administration tube 8 penetrates through the working box 1, an external connector 9 is installed at the end of the medicine administration tube 8, a control knob 14 is installed outside the working box 1, and the control knob 14 is electrically connected to the servo motor 11.

[0036] When enema administration is required for a patient, rotate the control knob 14 to drive the servo motor 11 to operate. The output shaft of the servo motor 11 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate through gear meshing. When the driven gear 13 rotates, it drives the screw rod 6 to move toward the side close to the inlet baffle 4 due to the threaded cooperation. When the screw rod 6 moves, it drives the push plate 5 to move synchronously. Through the transmission, the screw rod 6 drives the push plate 5 to move synchronously, and the push plate 5 will push the liquid medicine to flow out from the external connector 9 along the medicine administration tube 8 to achieve administration. By controlling the administration through the screw rod 6, the administration speed can be controlled, the administration efficiency and quality can be improved, and thus the treatment effect can be improved.

[0037] Limiting grooves 15 are opened on both sides of the driven gear 13. Four support plates 17 are symmetrically installed on the gear mounting plate 10. The support plates 17 and the limiting grooves 15 are connected by limiting columns 16. The limiting columns 16 are in rotational cooperation with both the limiting grooves 15 and the support plates 17.

[0038] The limiting post 16 can prevent the driven gear 13 from moving during transmission, which affects the transmission effect on the screw rod 6. Moreover, the rotational installation of the limiting post 16 can reduce the friction on the transmission gear 2307, reduce losses, and extend the service life of the parts.

[0039] A medicine storage box 19 is installed in the working box 1. A medicine inlet 21 is opened on the outlet baffle 3. The medicine storage box 19 is connected to the medicine inlet 21 through a liquid extraction pipe 20. A distance sensor 18 is installed on the inlet baffle 4.

[0040] In the initial state, the push plate 5 is close to the side of the outlet baffle 3. Before administering the enema liquid to the patient, turn the control knob 14 to start the servo motor 11. The output shaft of the servo motor 11 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate through gear meshing. When the driven gear 13 rotates, due to the thread fit, the screw rod 6 moves towards the side away from the inlet baffle 4. When the screw rod 6 moves, it drives the push plate 5 to move synchronously. The volume of the space between the push plate 5 and the outlet baffle 3 increases, and the pressure decreases. The liquid medicine is drawn out from the medicine storage box 19 and flows into the medicine administration cylinder 2. After the medicine extraction is completed, the control knob 14 can be turned to control the screw rod 6 to reverse for the medicine administration operation;

[0041] A liquid level display is installed outside the working box 1. The liquid level display is electrically connected to the distance sensor 18. Whether the medicine is being fed into the medicine administration cylinder 2 or administered outwards, the amount of medicine can be controlled through the data fed back by the distance sensor 18, which can improve the safety of medicine administration and further improve the medicine administration effect.

[0042] A temperature control component 22 and a cleaning component 23 are arranged in the working box 1. The temperature control component 22 is close to the side of the outlet baffle 3, and the cleaning component 23 is close to the side of the inlet baffle 4.

[0043] As Figure 1 、 Figures 3 - 4 and Figure 8 shown, the temperature control component 22 includes a temperature measurement port 2201, a temperature measurement column 2202, a temperature measurement gas 2203, a movable column 2204, a temperature measurement mounting plate 2205, a rotating seat 2206, a rotating ring 2207, a driving rod 2208, a driven rod 2209, a temperature adjustment seat 2210, a shielding arc block 2211, a photosensitive controller 2212, and a heating ring 2213;

[0044] The working box 1 is connected to the outlet baffle 3 through a temperature measuring mounting plate 2205. A temperature measuring column 2202 is installed on the temperature measuring mounting plate 2205. A temperature measuring port 2201 is provided on the medicine delivery tube 8. The end of the temperature measuring column 2202 extends into the temperature measuring port 2201. A movable column 2204 is slidably installed in the temperature measuring column 2202. A temperature measuring gas 2203 is injected into the space between the movable column 2204 and the bottom of the temperature measuring column 2202. A rotating seat 2206 is installed on one side of the working box 1 close to the outlet baffle 3. A rotating ring 2207 is rotatably installed on the rotating seat 2206. A driving rod 2208 and a driven rod 2209 are installed on the rotating ring 2207. The driving rod 2208 is located above the movable column 2204. A temperature adjusting seat 2210 is installed on one side of the outlet baffle 3 close to the temperature measuring mounting plate 2205. Three photosensitive controllers 2212 are installed on the temperature adjusting seat 2210. A shielding arc block 2211 is installed at the end of the driven rod 2209. A heating ring 2213 is sleeved outside the medicine delivery cylinder 2. The heating ring 2213 is electrically connected to the photosensitive controller 2212.

[0045] In the initial state, the shielding arc block 2211 shields the photosensitive controller 2212, and the heating ring 2213 does not work at this time. When administering medicine to a patient, the medicine liquid flows through the medicine delivery tube 8. When the temperature of the medicine liquid becomes lower, the volume of the temperature measuring gas 2203 decreases, and the movable column 2204 moves downward. Since the driving rod 2208 rests on the movable column 2204, the driving rod 2208 will move downward synchronously. The downward movement of the driving rod 2208 will drive the rotating ring 2207 to rotate clockwise, so that the driven rod drives the shielding arc block 2211 to also move downward. The shielding arc block 2211 will cancel the shielding of the photosensitive controller 2212. The photosensitive controller 2212 emits an electrical signal to control the heating ring 2213 to heat the medicine liquid in the medicine delivery cylinder 2, ensuring that the medicine liquid is always at a temperature suitable for the human body, preventing stress caused by too low temperature to the patient, and being able to improve the patient's medical experience and treatment effect.

[0046] Both the driving rod 2208 and the driven rod 2209 are fixed on the rotating ring 2207, and the length of the driving rod 2208 is less than the length of the driven rod 2209.

[0047] When the temperature change is small, the volume change of the gas is also relatively small. Therefore, the rotation amplitude of the driving rod 2208 will also be small. When the length of the driven rod 2209 is greater than that of the driving rod 2208, the movement amplitude of the driven rod 2209 will become larger, which is convenient for controlling the heating of the medicine liquid.

[0048] The three photosensitive controllers 2212 are arranged vertically along the temperature adjusting seat 2210, and the arc length of the shielding arc block 2211 is greater than the maximum distance between the three photosensitive controllers 2212.

[0049] Three photosensitive controllers 2212 correspond to different heating intensities of the heating ring 2213. When the temperature drops significantly, the downward movement amplitude of the shielding arc block 2211 becomes larger, the number of photosensitive controllers 2212 blocked becomes smaller, and the heating intensity of the corresponding heating ring 2213 becomes larger, which can heat the liquid medicine faster. The heating of the liquid medicine at different intensities can timely adjust the temperature of the liquid medicine, further ensuring that the liquid medicine is always at a temperature suitable for the human body.

[0050] As Figures 1 - 7 and Figures 9 - 11 shown, the cleaning assembly 23 includes a steam generator 2301, a steam channel 2302, a steam pipe 2303, a turntable 2304, an arc-shaped air duct 2305, air outlet holes 2306, a transmission gear 2307, a swing gear 2308, a transmission column 2309, a swing plate 2310, a mounting column 2311, a swing rod 2312, a linkage column 2313, a sleeve rod 2314, a cleaning arc plate 2315, a top spring 2316, a sewage outlet 2317, and a collection box 2318;

[0051] The steam generator 2301 is installed in the working box 1. The steam generator 2301 is electrically connected to the distance sensor 18. A steam channel 2302 is opened in the screw rod 6. The steam channel 2302 is connected to the steam generator 2301 through a steam pipe 2303. Air outlet holes 2306 are opened in the push plate 5. A turntable 2304 is rotatably installed in the push plate 5. An arc-shaped air duct 2305 is opened in the turntable 2304. The arc-shaped air duct 2305 is communicated with the steam channel 2302. A transmission gear 2307 is installed on the turntable 2304. A plurality of swing gears 2308 are rotatably installed on the push plate 5. All the plurality of swing gears 2308 are engaged with the transmission gear 2307. A transmission column 2309 is installed on the transmission gear 2307. The transmission column 2309 penetrates through the push plate 5. A swing plate 2310 is installed at the end of the transmission column 2309. A linkage column 2313 is eccentrically installed on the swing plate 2310. A swing rod 2312 is installed at the end of the linkage column 2313. A mounting column 2311 is installed on the push plate 5. The swing rod 2312 is rotatably installed on the mounting column 2311. A sleeve rod 2314 is slidably sleeved on the swing rod 2312. A cleaning arc plate 2315 is installed at the end of the sleeve rod 2314. A sewage outlet 2317 is opened in the inlet baffle 4. A collection box 2318 is installed in the working box 1.

[0052] When the screw 6 pushes the push plate 5 to move away from the side of the inlet baffle 4, and the steam generator 2301 determines that the device starts the drug administration operation according to the data transmitted back by the distance sensor 18, the steam generator 2301 fills the inside of the push plate 5 with high-temperature steam through the steam channel 2302. The high-temperature steam needs to flow out of the turntable 2304 from the arc-shaped air duct 2305 to enter the turntable 2304. Due to the special shape of the arc-shaped air duct 2305, when the high-temperature steam sprays out of the turntable 2304, it will push the turntable 2304 to rotate. When the turntable 2304 rotates, it drives the transmission gear 2307 to rotate synchronously. Due to the gear meshing effect, the transmission gear 2307 drives the swing gear 2308 to rotate. The swing gear 2308 drives the swing plate 2310 to rotate synchronously through the transmission column 2309. When the swing plate 2310 rotates, it drives the linkage column 2313 to rotate around the center of the swing plate 2310. Since the linkage column 2313 is eccentrically installed on the swing plate 2310, when the linkage column 2313 rotates, it will drive the sleeve rod 2314 and the cleaning arc plate 2315 to reciprocate around the mounting column 2311 through the swing rod 2312. When the cleaning arc plate 2315 reciprocates, it will clean the inside of the drug administration cylinder 2. At the same time, after the high-temperature steam sprays out of the turntable 2304, it is discharged into the drug administration cylinder 2 from the air outlet 2306. When the high-temperature steam contacts the wall surface of the drug administration cylinder 2, it will disinfect the wall of the drug administration cylinder 2 at high temperature and condense into water. The condensed water droplets will enhance the cleaning effect of the cleaning arc plate 2315 on the cylinder wall. By cleaning the inner wall of the drug administration cylinder 2 after drug administration with high-temperature steam and the cleaning arc plate 2315, the residue of the liquid medicine on the cylinder wall can be reduced, the inside of the drug administration cylinder 2 can be kept clean, and the continuous use of the subsequent equipment can be facilitated.

[0053] When the drug administration cylinder 2 pumps liquid again, when the push plate 5 moves toward the side of the inlet baffle 4, the push plate 5 will push the sewage out of the sewage outlet 2317 and flow into the collection box 2318, and a one-way valve is installed at the sewage outlet 2317 to prevent foreign substances from entering the drug administration cylinder 2.

[0054] The sleeve rod 2314 is connected to the end of the swing rod 2312 through a tightening spring 2316.

[0055] When the cleaning arc plate 2315 reciprocates, the distance between it and the swing rod 2312 will change. The tightening spring 2316 can make the cleaning arc plate 2315 always close to the wall of the drug administration cylinder 2 as the cleaning arc plate 2315 moves, further improving the cleaning effect.

[0056] The working principle of the present invention:

[0057] When enema fluid needs to be administered to a patient, rotate the control knob 14 to drive the servo motor 11 to operate. The output shaft of the servo motor 11 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate through gear meshing. When the driven gear 13 rotates, it drives the screw rod 6 to move towards the side close to the inlet baffle 4 due to thread fit. When the screw rod 6 moves, it drives the push plate 5 to move synchronously. Through the transmission, the screw rod 6 drives the push plate 5 to move synchronously, and the push plate 5 will push the liquid medicine to flow out from the external joint 9 along the medicine delivery tube 8 to achieve drug administration. By controlling the drug administration with the screw rod 6, the drug administration speed can be controlled, the drug administration efficiency and quality can be improved, and thus the treatment effect can be improved.

[0058] The limit post 16 can prevent the driven gear 13 from moving during transmission and affecting the transmission effect on the screw rod 6. Moreover, the rotational installation of the limit post 16 can reduce the friction on the transmission gear 2307, reduce losses, and extend the service life of the parts.

[0059] In the initial state, the push plate 5 is close to the side of the outlet baffle 3. Before enema fluid needs to be administered to a patient, rotate the control knob 14 to start the servo motor 11. The output shaft of the servo motor 11 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 13 to rotate through gear meshing. When the driven gear 13 rotates, it drives the screw rod 6 to move towards the side away from the inlet baffle 4 due to thread fit. When the screw rod 6 moves, it drives the push plate 5 to move synchronously. The volume of the space between the push plate 5 and the outlet baffle 3 increases, the pressure decreases, and the liquid medicine is drawn from the medicine storage box 19 and flows into the medicine delivery cylinder 2. After the medicine drawing is completed, the control knob 14 can be rotated to control the screw rod 6 to reverse for drug administration operation;

[0060] A liquid level display is installed outside the working box 1. The liquid level display is electrically connected to the distance sensor 18. Whether the medicine is being fed into the medicine delivery cylinder 2 or being administered outward, the amount of medicine can be controlled through the data fed back by the distance sensor 18, which can improve the safety of drug administration and further improve the drug administration effect.

[0061] In the initial state, the shielding arc block 2211 shields the photosensitive controller 2212, and the heating ring 2213 does not work at this time. When administering medicine to a patient, the liquid medicine flows through the medicine delivery tube 8. When the temperature of the liquid medicine becomes low, the volume of the temperature-measuring gas 2203 decreases, the movable column 2204 moves downward, and the driving rod 2208 is stopped on the movable column 2204, so the driving rod 2208 will move downward synchronously. The downward movement of the driving rod 2208 will drive the rotating ring 2207 to rotate clockwise, so that the driven rod drives the shielding arc block 2211 to also move downward. The shielding arc block 2211 will cancel the shielding of the photosensitive controller 2212, and the photosensitive controller 2212 sends an electrical signal to control the heating ring 2213 to heat the liquid medicine in the medicine cylinder 2, ensuring that the liquid medicine is always at a temperature suitable for the human body, preventing stress caused by too low temperature to the patient, and improving the patient's medical experience and treatment effect.

[0062] When the temperature change is small, the volume change of the gas is also relatively small, so the rotation amplitude of the driving rod 2208 will also be small. When the length of the driven rod 2209 is greater than that of the driving rod 2208, the movement amplitude of the driven rod 2209 will become larger, which is convenient for controlling the heating of the liquid medicine.

[0063] The three photosensitive controllers 2212 correspond to different heating intensities of the heating ring 2213. When the temperature drops significantly, the downward movement amplitude of the shielding arc block 2211 becomes larger, the number of photosensitive controllers 2212 shielded becomes smaller, and the corresponding heating intensity of the heating ring 2213 becomes larger, which can heat the liquid medicine faster. The heating of the liquid medicine at different intensities can timely regulate the temperature of the liquid medicine, further ensuring that the liquid medicine is always at a temperature suitable for the human body.

[0064] When the screw 6 pushes the push plate 5 to move away from the inlet baffle 4, and the steam generator 2301 determines that the device starts the drug administration operation according to the data transmitted back by the distance sensor 18, the steam generator 2301 fills the inside of the push plate 5 with high-temperature steam through the steam channel 2302. The high-temperature steam needs to flow out of the turntable from the arc-shaped air duct 2305 to enter the turntable 2304. Due to the special shape of the arc-shaped air duct 2305, when the high-temperature steam sprays out of the turntable 2304, it will push the turntable 2304 to rotate. When the turntable 2304 rotates, it drives the transmission gear 2307 to rotate synchronously. Due to the gear meshing effect, the transmission gear 2307 drives the swing gear 2308 to rotate. The swing gear 2308 drives the swing plate 2310 to rotate synchronously through the transmission column 2309. When the swing plate 2310 rotates, it drives the linkage column 2313 to rotate around the center of the swing plate 2310. Since the linkage column 2313 is eccentrically installed on the swing plate 2310, when the linkage column 2313 rotates, it will drive the sleeve rod 2314 and the cleaning arc plate 2315 to reciprocate around the mounting column 2311 through the swing rod 2312. When the cleaning arc plate 2315 reciprocates, it will clean the inside of the drug administration cylinder 2. At the same time, after the high-temperature steam sprays out of the turntable 2304, it is discharged into the drug administration cylinder 2 from the air outlet 2306. When the high-temperature steam contacts the wall of the drug administration cylinder 2, it will disinfect the wall of the drug administration cylinder 2 at high temperature and condense into water. The condensed water droplets will enhance the cleaning effect of the cleaning arc plate 2315 on the cylinder wall. By using high-temperature steam and the cleaning arc plate 2315 to clean the inner wall of the drug administration cylinder 2 after drug administration, the residue of the liquid medicine on the cylinder wall can be reduced, the inside of the drug administration cylinder 2 can be kept clean, and it is convenient for the subsequent continuous use of the device. When the drug administration cylinder 2 pumps liquid again, when the push plate 5 moves towards the side close to the inlet baffle 4, the push plate 5 will push the sewage out of the sewage outlet 2317 and flow into the collection box 2318, and a one-way valve is installed at the sewage outlet 2317 to prevent foreign substances from entering the drug administration cylinder 2.

[0065] When the cleaning arc plate 2315 reciprocates, the distance between it and the swing rod 2312 will change. The pressing spring 2316 can make the cleaning arc plate 2315 always close to the wall of the drug administration cylinder 2 as the cleaning arc plate 2315 moves, further improving the cleaning effect.
