Description

Technical Field

[0001] The invention relates to the technical field of enema, in particular to a refined anti-splashing enema mechanism. Background Art

[0002] Enema is a medical procedure, mainly used to treat certain intestinal diseases, such as intestinal obstruction or severe constipation. During enema, the doctor will inject a special enema solution or saline solution into the patient's intestines to help clean the intestines and solve the problem of fecal accumulation. During enema, the patient needs to take a specific posture, such as left lateral position or supine position, so that the enema solution can flow smoothly into the intestines. The doctor will use appropriate enema equipment to inject the enema solution into the intestines. Enema has certain risks and precautions. Patients need to confirm whether they are suitable for enema. For example, patients with intestinal inflammation, intestinal ulcers, etc. should not undergo enema. The selection and use of enema solution needs to be determined according to the patient's specific situation. The temperature and concentration of the enema solution also need to be adjusted according to the patient's physical condition.

[0003] During the enema process, the flow rate and pressure of the enema solution are usually controlled by the doctor to ensure that the enema solution can flow into the intestine slowly and evenly. The patient needs to stay relaxed and avoid excessive tension and contraction of the intestine to avoid affecting the flow and treatment effect of the enema solution. The enema solution will stimulate intestinal peristalsis to help defecation. The enema solution usually needs to stay in the intestine for a period of time before being discharged from the body. When the patient receives enema treatment for the first time, he or she will usually feel nervous. When the enema solution stimulates defecation, he or she may not be able to hold it back, which will cause the enema solution and feces to splash out, causing certain pollution. For this reason, we propose a refined anti-splash enema mechanism. Summary of the invention

[0010] Preferably, guiding blocks are fixedly installed on both sides of each clamping piece. Guiding grooves for limiting the guiding blocks are arranged on the inner walls on both sides of each chute. Each guiding block is slidably installed in the corresponding guiding groove.

[0011] Preferably, rubber heads are fixedly installed at one end of each anal tube. A number of liquid outlet holes for assisting the input of enema liquid are arranged on the rubber heads.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When the anal tube of the present invention is pulled out, the rubber head compresses the sliding block into the compression groove, driving the second pull rope to pull the clamping block into the clamping groove, releasing the limit of the clamping block on the clamping part. The elastic force of the torsion spring drives the roller shaft to wind up the first pull rope, unfolds the absorption pad, and attaches the absorption pad to the patient's buttocks through the cushion plate to absorb the splashes generated during the enema process of the patient, preventing splashing and causing pollution.

[0019] The present invention uses a pressure sensor to detect the hydraulic pressure of the enema solution in the catheter. When the pressure changes, the patient may feel discomfort, and the position of the anal tube can be adjusted in time, and the amount of enema solution injected is recorded to prevent too much or too little enema solution from being injected. The flow rate of the enema solution in the catheter is controlled by the threaded kit and the collar and the wedge-shaped block, preventing the enema solution from being input too fast or too slow and causing discomfort to the patient.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 10, the present invention provides a technical solution: a refined anti-splash enema mechanism, including a liquid storage bag 1, a catheter 4 fixedly installed at the bottom of the liquid storage bag 1, a liquid injection port 2 provided at the upper end of the liquid storage bag 1, two hanging ropes 3 fixedly installed on the liquid storage bag 1 for hanging it at a high place, a communicating vessel 39 fixedly installed at one end of the catheter 4, an anal tube 5 fixedly installed on the communicating vessel 39, rubber heads 6 fixedly installed at one end of each anal tube 5, and a plurality of liquid outlet holes 7 for assisting the input of enema liquid provided on the rubber heads 6. A pressure tube 8 is fixedly installed on the catheter 4, both ends of the pressure tube 8 are communicated with the catheter 4, a first funnel 9 and a second funnel 10 are fixedly installed inside the pressure tube 8, and the pressure tube 8, the first funnel 9 and the second funnel 10 are all made of elastic materials. When the first funnel 9 and the second funnel 10 are not squeezed, it does not affect the passage of enema liquid. When the anal tube 5 is blocked or the pressure in the catheter 4 is insufficient and the enema liquid cannot be input into the body, squeeze the pressure tube 8. The enema liquid in the pressure tube 8 flows towards both ends. After the first funnel 9 is squeezed, the lower end of it is pushed by the enema liquid and deforms upward, so that the opening at the lower end of the first funnel 9 is blocked, and the enema liquid in the upper liquid storage bag 1 no longer enters the pressure tube 8. The second funnel 10 deforms downward, which does not affect the flow of enema liquid. The enema liquid in the pressure tube 8 all flows downward, increasing the flow rate at the anal tube 5. When the pressure tube 8 is released, it restores itself through its own elasticity, and the enema liquid in the catheter 4 at both ends is sucked into the pressure tube 8. When the enema liquid at the lower end moves upward, it pushes the second funnel 10 upward to close it, preventing the enema liquid that has been injected into the body from being sucked back. At the same time, the first funnel 9 returns to its original state, so that the enema liquid in the upper liquid storage bag 1 is sucked into the pressure tube 8. A threaded kit 11 is fixedly installed on the catheter 4, and a collar 12 that cooperates with it is threadedly installed on the threaded kit 11. A plurality of rotating grooves 13 are provided on the threaded kit 11, and a wedge-shaped block 14 is rotatably installed in each rotating groove 13. When the collar 12 is rotated downward, the collar 12 gradually compresses the wedge-shaped block 14 into the threaded kit 11, squeezing the catheter 4 and reducing the internal flow rate. When the collar 12 is rotated upward, the collar 12 releases the limit on the wedge-shaped block 14, and through the elastic force of the catheter 4 itself, the wedge-shaped block 14 is pushed up, increasing the flow rate in the catheter 4. The edge of each wedge-shaped block 14 is set to a smooth circular arc to prevent the catheter 4 from being cut and scratched, resulting in liquid leakage. And when several wedge-shaped blocks 14 are combined, they will prevent the enema liquid in the catheter 4 from flowing through. A pressure sensor 40 for detecting the hydraulic pressure of the enema liquid in the catheter 4 is fixedly installed at the bottom of the liquid storage bag 1. When the pressure changes, it indicates that the patient may be uncomfortable and the position of the anal tube 5 needs to be adjusted in time. And the pressure sensor 40 can record the amount of enema liquid injected, preventing the patient from being uncomfortable due to excessive injection of enema liquid, or not achieving a good treatment effect due to too little injection;

[0033] A backing plate 15 is slidably mounted on the anal tube 5. The backing plate 15 is arranged in an arc shape conforming to the shape of the human buttocks. The backing plate 15 is made of an elastic material. An adhesive 16 is fixedly mounted on one side edge of the backing plate 15. An absorbent pad 17 for absorbing splashes is also mounted on the backing plate 15. The absorbent pad 17 is made of a flexible material, and one end of it is fixedly connected to the backing plate 15. When sliding the backing plate 15 onto the anal tube 5, the absorbent pad 17 needs to be wound up first so that it does not hinder the extrusion of the anal tube 5 for infusion. Then, the anal tube 5 is inserted into the human body to input the enema fluid, and the backing plate 15 is fixed to a suitable position on the human body through the adhesive 16. Two device grooves 18 are symmetrically arranged on the backing plate 15. A sleeve 20 is fixedly mounted in each device groove 18. A roller shaft 21 is slidably mounted in each sleeve 20. A torsion spring 22 is fixedly mounted at one end of each roller shaft 21. One end of each torsion spring 22 is fixedly connected to the corresponding roller shaft 21, and the other end is fixedly connected to the inner wall of the corresponding device groove 18. Connecting pieces 25 are fixedly mounted on both sides of one end of the absorbent pad 17. A first pull rope 23 is fixedly connected between each connecting piece 25 and the corresponding roller shaft 21. Each first pull rope 23 is made of a flexible material. An elastic rod 26 is fixedly mounted on each connecting piece 25. A clamping piece 27 is fixedly mounted at the lower end of each elastic rod 26. Two sliding grooves 19 are arranged on the backing plate 15, and the sliding grooves 19 correspond to the clamping pieces 27 one by one. Guide blocks 28 are fixedly mounted on both sides of each clamping piece 27. Guide grooves 24 for limiting the guide blocks 28 are arranged on the inner walls of both sides of each sliding groove 19. Each guide block 28 is slidably mounted in the corresponding guide groove 24. When the absorbent pad 17 is wound up, it drives the connecting pieces 25 at both ends to move synchronously. The connecting pieces 25 at both ends stretch the first pull ropes 23 at both ends. When the first pull ropes 23 are stretched, the roller shaft 21 drives one end of the torsion spring 22 to rotate. While the roller shaft 21 rotates, it moves towards the inside of the sleeve 20, so that the torsion spring 22 is stretched. Through the limitation of the guide blocks 28 by the guide grooves 24, the connecting pieces 25 at both ends drive the corresponding elastic rods 26 and the corresponding clamping pieces 27 to move along the corresponding sliding grooves 19;

[0034] On the inner wall of each chute 19, a limiting groove 30 is provided. A clamping block 32 is slidably installed in each limiting groove 30. Each clamping member 27 is provided with a clamping groove 29 that cooperates with the clamping block 32. Each clamping block 32 is configured as a wedge shape, with one side being an inclined surface and the other side being a right-angle surface. The inner wall of each clamping groove 29 is a right-angle surface. One end of each clamping block 32 is fixedly installed with a spring 31. One end of each spring 31 is fixedly connected to the inner wall of the limiting groove 30. When the clamping member 27 moves along the chute 19 and contacts the inclined surface of the clamping block 32, it will cause the clamping block 32 to move into the limiting groove 30 and compress the corresponding spring 31. When the clamping groove 29 moves to the position of the clamping block 32, the clamping member 27 releases the limitation on the clamping block 32. The clamping block 32 is ejected by the elastic force of the spring 31. Through the cooperation between the right-angle surface of the clamping block 32 and the inner wall of the clamping groove 29, the clamping block 32 fixes the clamping member 27. After the absorbent pad 17 is completely wound up, both side clamping members 27 are fixed by the corresponding clamping blocks 32. A fixing ring 34 is fixedly installed on the backing plate 15. A compression groove 36 is provided on the fixing ring 34. The compression groove 36 penetrates through the fixing ring 34 and extends into the backing plate 15. A sliding block 37 is slidably installed in the compression groove 36. One end of the sliding block 37 is fixedly installed with an elastic column 38. One end of the elastic column 38 is fixedly connected to the inner wall of the compression groove 36. Second pull ropes 33 are symmetrically and fixedly installed on both sides of the sliding block 37. One end of each second pull rope 33 is fixedly connected to the corresponding clamping block 32. Each second pull rope 33 is made of a flexible material and is in a taut state. A cleaning cloth 35 is slidably installed on the fixing ring 34. One end of the cleaning cloth 35 is located inside the fixing ring 34, and the other end is stacked outside the fixing ring 34. The diameter of the rubber head 6 is larger than the diameter of the fixing ring 34. When the enema fluid injection is completed, the anal tube 5 needs to be pulled out from the patient's body. When pulling out, the anal tube 5 passes through the fixing ring 34. Since the diameter of the rubber head 6 is larger than the diameter of the fixing ring 34, when the rubber head 6 passes through the fixing ring 34, the rubber head 6 is deformed by extrusion and closely adheres to the inner wall of the fixing ring 34. The end of the rubber head 6 will drive one end of the cleaning cloth 35 to move together and pull the cleaning cloth 35 out of the fixing ring 34. The stacked end of the cleaning cloth 35 will be unfolded and gradually wrap around the rubber head 6 as the rubber head 6 moves, preventing the dirt remaining on the rubber head 6 from contaminating the backing plate 15. When the rubber head 6 is pulled out, it contacts the inclined surface of the sliding block 37, causing the sliding block 37 to drive the second pull ropes 33 on both sides into the compression groove 36 and compress the elastic column 38. The second pull ropes 33 on both sides respectively pull the corresponding clamping blocks 32 into the limiting groove 30, causing the clamping blocks 32 to release the limitation on the clamping members 27. The corresponding rollers 21 are reset by the elastic force of the torsion springs 22 at both ends, and the first pull ropes 23 on both sides are wound up, driving the connecting member 25 and the elastic rod 26 and the clamping member 27 to reset along the chute 19, so that the absorbent pad 17 unfolds to collect the splashed splashes. After the rubber head 6 is pulled out, the elastic column 38 drives the sliding block 37 to reset again.The spring 31 also pushes the clamping block 32 to reset, and the second draw ropes 33 on both sides remain in a taut state.

[0035] Specifically, before use, the absorbent pad 17 needs to be wound up first so that it does not hinder the extrusion of the anal tube 5 for infusion. Then, the backing plate 15 is slidably installed on the anal tube 5, and the anal tube 5 is inserted into the human body. The backing plate 15 is fixed to a suitable position on the human body through the adhesive 16. When the absorbent pad 17 is wound up, the connecting members 25 at both ends thereof move synchronously. The connecting members 25 at both ends thereof stretch the first draw ropes 23 at both ends. When the first draw ropes 23 are stretched, the roller shaft 21 drives one end of the torsion spring 22 to rotate. While the roller shaft 21 rotates, it moves into the sleeve 20, causing the torsion spring 22 to be stretched. Through the limitation of the guide block 28 by the guide groove 24, the connecting members 25 at both ends drive the corresponding elastic rods 26 and the corresponding clamping members 27 to move along the corresponding sliding grooves 19. When the clamping member 27 moves along the sliding groove 19 and contacts the inclined surface of the clamping block 32, the clamping block 32 will be pushed into the limiting groove 30, and the corresponding spring 31 will be compressed. When the clamping groove 29 moves to the position of the clamping block 32, the clamping member 27 releases the limitation on the clamping block 32. The clamping block 32 is ejected by the elastic force of the spring 31. Through the cooperation of the right-angle surface of the clamping block 32 and the inner wall of the clamping groove 29, the clamping block 32 fixes the clamping member 27. After the absorbent pad 17 is completely wound up, the clamping members 27 on both sides are fixed by the corresponding clamping blocks 32;

[0036] Before the anal tube 5 is inserted into the human body, the collar 12 should be located at the bottom of the threaded kit 11. Through the limitation of the wedge block 14 by the collar 12, the wedge block 14 is combined to prevent the enema fluid from flowing. After the anal tube 5 is inserted into the human body, the collar 12 is slowly rotated upward. The collar 12 releases the limitation on the wedge block 14. Through the self-elastic force of the catheter 4, the wedge block 14 is pushed up, increasing the flow rate in the catheter 4. When the anal tube 5 is blocked or the pressure in the catheter 4 is insufficient, resulting in the enema fluid being unable to be infused into the body, the pressure tube 8 is squeezed. The enema fluid in the pressure tube 8 flows to both ends. After the first funnel 9 is squeezed, the lower end thereof is pushed upward by the enema fluid and deforms, blocking the opening at the lower end of the first funnel 9. The enema fluid in the upper storage bag 1 no longer enters the pressure tube 8. The second funnel 10 deforms downward, not affecting the flow of the enema fluid. The enema fluid in the pressure tube 8 all flows downward, increasing the flow rate at the anal tube 5. When the pressure tube 8 is released, it restores itself through its own elasticity. The enema fluid in the catheters 4 at both ends is sucked into the pressure tube 8. When the enema fluid at the lower end moves upward, the second funnel 10 is pushed upward and closed, preventing the enema fluid that has been injected into the body from being sucked back. At the same time, the first funnel 9 returns to its original state, sucking the enema fluid in the upper storage bag 1 into the pressure tube 8;

[0037] When the enema fluid injection is completed, the anal tube 5 needs to be pulled out from the patient's body. When the anal tube 5 is pulled out, it passes through the fixing ring 34. Since the diameter of the rubber head 6 is larger than the diameter of the fixing ring 34, when the rubber head 6 passes through the fixing ring 34, the rubber head 6 is squeezed and deformed and adheres to the inner wall of the fixing ring 34. One end of the cleaning cloth 35 will be driven to move together with the end of the rubber head 6, and the cleaning cloth 35 will be taken out from the fixing ring 34. The piled-up end of the cleaning cloth 35 will be unfolded and gradually wrap around the rubber head 6 as the rubber head 6 moves, preventing the dirt remaining on the rubber head 6 from contaminating the backing plate 15. When the rubber head 6 is pulled out, it contacts the inclined surface of the sliding block 37, causing the sliding block 37 to drive the second pull ropes 33 on both sides into the compression groove 36, and the elastic column 38 is compressed. The second pull ropes 33 on both sides respectively pull the corresponding clamping blocks 32 into the limiting groove 30, so that the clamping blocks 32 release the limitation on the clamping member 27. Driven by the elastic force of the torsion springs 22 at both ends, the corresponding roller shafts 21 are reset, and the first pull ropes 23 on both sides are wound up, driving the connecting member 25 and the elastic rod 26 and the clamping member 27 to reset along the sliding groove 19, so that the absorption pad 17 is unfolded to collect the splashed substances. After the rubber head 6 is pulled out, the elastic column 38 drives the sliding block 37 to reset again, and the spring 31 also pushes the clamping block 32 to reset, and the second pull ropes 33 on both sides remain in a taut state.
