Description

Technical Field

[0001] This invention relates to the field of enterostomy teaching model technology, and in particular to a multifunctional enterostomy teaching model. Background Technology

[0002] The use of enterostomy teaching models is a crucial component of clinical skills training, its necessity stemming from ethical requirements in medical education, risk control, and the need to improve teaching efficiency. This is especially true for the installation of ostomy bags, which directly impacts patients' quality of life and comfort. Allowing inexperienced trainees to practice directly on patients increases the risks of pain, infection, and leakage, disrespecting patient safety and dignity. Furthermore, different patients have different stoma shapes and characteristics, including whether the stoma is protruding, flat, or retracted. Handling these varying situations is a fundamental skill for healthcare professionals, but previous teaching models featured fixed stoma positions and shapes, hindering medical education on stoma care.

[0008] Preferably, the drive assembly includes a vertical double-suction pump fixedly installed at the lower end of the storage tank. A connecting pipe is fixedly installed between one port of the vertical double-suction pump and the water tank, and a T-shaped pipe is fixedly installed at the other port of the vertical double-suction pump.

[0011] Preferably, the rotating shaft of the sealing sheet passes through the upper and lower sides of the pull tube, the two sets of openings are staggered, the openings communicate with the pull tube, and the upper and lower ends of the torsion spring are respectively inserted into the disc and the pull tube.

[0012] Preferably, the vertical double-suction pump is connected to an external electrical control device for the electric control valve, and the water guide pipe is connected to the cylinder at the position corresponding to the liquid chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By opening the two sets of water inlet caps, liquid and pigment can be added to the water tank and pigment tank respectively, which facilitates subsequent teaching and simulation work on the model by medical staff. When in use, by operating the vertical double suction pump, in conjunction with opening the electric control valve on the second hose side and closing the electric control valve on the water guide pipe side, liquid can be introduced into the tube and flow out from the rubber stoma piece to simulate excretion. Opening the electric control valve on the water guide pipe side and closing the electric control valve on the second hose side will increase and extract liquid on the inner wall of the liquid chamber, thereby driving the displacement component.

[0015] 2. When guiding liquid in the tube, push out the sealing plate and rotate it, which will drive the connected disc and disc to rotate. The disc will cause the two sets of ports to overlap, and the lower disc will twist the torsion spring. At the same time, the first tube will introduce the pigment into the liquid in the tube, which will adjust the color of the liquid to make it more like real excrement and make it easier for the operator to observe.

[0016] 3. When infusing or aspirating fluid into the liquid cavity through the water inlet pipe, the sealing ring is pushed or pulled back, and the pull tube moves inside the inner ring. At the same time, the first spring is squeezed. The pull tube and several sets of sliders pull or push one end of the rubber stoma piece and the L-shaped ring respectively, sliding along the sliding opening. This allows for adjustment of the length of the rubber stoma piece protruding outward from the model body or pulling it back to flatten or indent it, simulating the operator's handling of different stoma states.

[0017] 4. Since the shape of the stoma varies depending on the patient, when the rubber stoma piece protrudes from the outside of the model body, pressing is performed through the textured area on the outside of the rubber stoma piece to push the corresponding deformation rod to rotate along the connecting shaft. The connection between the deformation rod and the connecting shaft pushes the locking block downwards, pushing the control rod backwards. The upper block squeezes the second spring. After rotating to a suitable angle, the compressed second spring pushes the control rod, which pushes the first movable opening and locks into the corresponding set of slots. This positions one side of the rotated deformation rod while stretching the elastic band, and the other side squeezes the rubber stoma piece. Pressing several textured areas according to the simulated irregular stoma allows for deformation adjustment of the rubber stoma piece at different positions. By pulling the tube and slider, the lower block and control rod are pulled. After the control rod is pulled to move a certain distance, the other lower block pulls the sliding opening. When the control rod is pulled first, the locking block moves downwards, unlocking the deformation rod. Under the elastic action of the elastic band, the deformation rod returns to its original state, facilitating subsequent work. Attached Figure Description

[0029] Please see Figures 1-8An embodiment of the present invention provides a multifunctional enterostomy teaching model, comprising a model body 1, a storage box 2 fixedly mounted on the upper end of the model body 1, two sets of displacement components 3 disposed inside the model body 1 near the front inner wall, a marking component 4 disposed on the rear side of each of the two sets of displacement components 3, and a driving component 5 disposed on the rear side of each of the two sets of marking components 4, the storage box 2 including a water tank 21 fixedly mounted on the upper end of the model body 1 near the rear side, a paint tank 22 fixedly mounted on the front side of the water tank 21, and a water filling cap 23 fixedly mounted on the upper side of both the water tank 21 and the paint tank 22, the displacement components 3 including a fixing ring 31 fixedly mounted on the front inner wall of the model body 1, a cylinder 32 fixedly mounted inside the fixing ring 31, and an inner... A limiting ring 34 is fixedly installed on the inner side of the inner ring 33 near the rear side of the inner ring 33. A liquid cavity 35 is provided between the inner ring 33 and the limiting ring 34. A movable cavity 36 is provided between the limiting ring 34 and the inner wall of the rear side of the cylinder 32. A pull tube 37 is movably installed on the inner side of the cylinder 32 and the inner ring 33. A sealing ring 38 is fixedly installed on the outer side of the pull tube 37 at one end of the limiting ring 34. A first spring 39 is sleeved between the sealing ring 38 and the inner wall of the movable cavity 36. A rubber venting piece 310 is fixedly installed on one end of the pull tube 37 and the cylinder 32. A sticking tube 311 is fixedly installed on the outer side of the pull tube 37 at the front end of the inner ring 33. Six sets of sliding mouths 312 are opened on the outer side of the sticking tube 311. A slider 313 is fixedly installed on the outer side of the pull tube 37 at the corresponding positions of the six sets of sliding mouths 312.

[0030] The inner ring 33 and the tube 311 are attached to the outside of the pull tube 37. The pull tube 37 passes through the rear side of the cylinder 32. The sealing ring 38 is attached to the inner wall of the movable cavity 36. The rubber sprue 310 is made of soft memory rubber material. The rubber sprue 310 passes through the inner wall of the model body 1. The outer side of the rubber sprue 310 is provided with six sets of textured areas. The slider 313 is slidably disposed in the slide 312.

[0031] When fluid is infused or aspirated from the liquid chamber 35 through the water pipe 55, the sealing ring 38 and the pull tube 37 are pushed or pulled back to move inside the inner ring 33, while the first spring 39 is squeezed. The pull tube 37 and several sets of sliders 313 pull or push one end of the rubber stoma piece 310 and the L-shaped ring 314 respectively, sliding along the sliding opening 312, so as to adjust the length of the rubber stoma piece 310 protruding outward from the model body 1 or pull it back to flatten or indent it, simulating the operator's handling of different stoma states.

[0032] An L-shaped ring 314 is fitted around the outer side of the pull tube 37 near the front end of the slider 313. Six sets of mounting seats 315 are fixedly installed on the outer side of the L-shaped ring 314. A first movable opening 316 is opened on the inner side of the mounting seat 315. A locking block 317 is slidably installed inside the first movable opening 316. A second movable opening 318 is opened inside the front side of the mounting seat 315. A third movable opening 319 is opened inside the rear side of the mounting seat 315. A control rod 320 is slidably installed inside the second movable opening 318 and the third movable opening 319. The upper end of the control rod 320 corresponds to the third movable opening 319. A top block 321 is fixedly installed at position 19. A second spring 322 is fixedly installed between the top block 321 and the inner wall of the rear side of the third movable opening 319. Two sets of bottom blocks 323 are fixedly installed on the rear side of the control rod 320. A connecting shaft 324 is fixedly installed at one end of the slide 312 corresponding to the upper position of each set of mounting bases 315. A deformable rod 325 is rotatably installed inside the connecting shaft 324. An elastic band 326 is fixedly installed between the deformable rod 325 and the slide 312. Five sets of slots 327 are opened on the lower side of the connection between the deformable rod 325 and the connecting shaft 324.

[0033] The first movable opening 316 has an arc-shaped opening on its inner side. The upper side of the locking block 317 is arc-shaped. The locking block 317 is engaged in the locking groove 327. The control rod 320 passes through the inner opening of the locking block 317. The front side of the control rod 320 is inclined to correspond to the position of the second movable opening 318. The control rod 320 passes through the rear side of the sliding opening 312. The rear one of the two sets of lower blocks 323 is in contact with the rear end of the slider 313. The other set of the two sets of lower blocks 323 is located at a partial position on the front side of the sliding opening 312. The front side of the deformation rod 325 is provided with three sets of round shafts corresponding to the textured area on the rubber sprue 310.

[0034] Since the shape of the stoma varies depending on the patient, when the rubber stoma piece 310 protrudes outside the model body 1, pressing is applied through the textured area on the outer side of the rubber stoma piece 310 to push the corresponding deformation rod 325 to rotate along the connecting shaft 324. The connection between the deformation rod 325 and the connecting shaft 324 pushes the locking block 317 downward, pushing the control rod 320 to move backward. The upper block 321 compresses the second spring 322. After rotating to a suitable angle, the compressed second spring 322 pushes the control rod 320, which in turn pushes the first movable opening 316, locking it into a set of corresponding slots 327. The deformable rod 325 is positioned on one side and stretches the elastic band 326 at the same time. On the other side, it squeezes the rubber stoma sheet 310. According to the simulated irregular stoma, several sets of textured areas are pressed to adjust the deformation of the rubber stoma sheet 310 at different positions. The lower block 323 and the control rod 320 are pulled by the pull tube 37 and the slider 313. After the control rod 320 is pulled and moved a certain distance, the other set of lower blocks 323 pulls the slide 312. When the control rod 320 is pulled first, the locking block 317 will move downward and unlock the deformable rod 325. Under the elastic action of the elastic band 326, the deformable rod 325 returns to its original state, which facilitates subsequent work.

[0035] The marking assembly 4 includes a hollow shell 41 fixedly disposed on the rear side of the pull tube 37. A first flexible tube 42 is fixedly disposed between the hollow shell 41 and the paint box 22. A sealing plate 43 is rotatably disposed inside the pull tube 37 corresponding to the position of the hollow shell 41. A side baffle 44 is fixedly disposed on the inner wall of the pull tube 37 on the side that is in contact with the sealing plate 43. A disc 45 is fixedly disposed on the upper side of the rotating shaft of the sealing plate 43. An opening 46 is provided inside the disc 45 near the rear side and on the upper side of the pull tube 37. A circular piece 47 is fixedly disposed on the lower side of the rotating shaft of the sealing plate 43. A torsion spring 48 is sleeved between the circular piece 47 on the outer side of the rotating shaft of the sealing plate 43 and the pull tube 37.

[0036] The rotating shaft of the sealing plate 43 passes through the upper and lower sides of the pull tube 37. The two sets of ports 46 are staggered and communicate with the pull tube 37. The upper and lower ends of the torsion spring 48 are inserted into the disc 47 and the pull tube 37 respectively.

[0037] When the liquid is guided through the tube 37, the sealing plate 43 is pushed out and rotated, which drives the connected disc 45 and disc 47 to rotate. The disc 45 drives the two sets of ports 46 to overlap, and the lower disc 47 twists the torsion spring 48. At the same time, the first tube 42 introduces the pigment into the liquid in the tube 37, which adjusts the color of the liquid to make it more like real excrement and makes it easier for the operator to observe.

[0038] The drive assembly 5 includes a vertical double-suction pump 51 fixedly installed at the lower end of the storage tank 2. A connecting pipe 52 is fixedly installed between one port of the vertical double-suction pump 51 and the water tank 21. A T-shaped pipe 53 is fixedly installed at the other port of the vertical double-suction pump 51. An electric control valve 54 is fixedly installed on both sides of the T-shaped pipe 53. A water guide pipe 55 is fixedly installed between one side of the T-shaped pipe 53 and the cylinder 32. A second flexible hose 56 is fixedly installed between the other side of the T-shaped pipe 53 and the rear side of the pull pipe 37.

[0039] The vertical double-suction pump 51 is connected to the external electrical control equipment of the electric control valve 54, and the water guide pipe 55 is connected to the cylinder 32 at the position corresponding to the liquid chamber 35.

[0040] By opening the two sets of water inlet caps 23, liquid and pigment can be added to the water tank 21 and pigment tank 22 respectively, which facilitates subsequent teaching and simulation work by medical staff on the model body 1. In use, by operating the vertical double suction pump 51, in conjunction with opening the electric control valve 54 on one side of the second hose 56 and closing the electric control valve 54 on the side of the water guide pipe 55, liquid can be introduced into the inside of the pull tube 37 and flow out from the rubber stoma piece 310 to simulate excrement. Opening the electric control valve 54 on the side of the water guide pipe 55 and closing the electric control valve 54 on the side of the second hose 56 will increase and extract liquid on the inner wall of the liquid chamber 35, thereby driving the displacement component 3.

[0041] Working principle: First, by opening the two sets of water inlet caps 23, liquid and pigment are added to the water tank 21 and pigment tank 22 respectively, facilitating subsequent teaching and simulation work by medical personnel on the model body 1. During use, the vertical double-suction pump 51, in conjunction with opening the electric control valve 54 on one side of the second hose 56 and closing the electric control valve 54 on the side of the water guide pipe 55, allows liquid to be introduced into the pull tube 37, flowing out from the rubber stoma piece 310 to simulate excrement. Opening the electric control valve 54 on the side of the water guide pipe 55 and closing the electric control valve 54 on the side of the second hose 56 increases and decreases the liquid inside the liquid chamber 35, driving the displacement component 3. Additionally, liquid is introduced into the pull tube 37... When guiding the liquid, the sealing plate 43 is pushed out and rotated, causing the connected disc 45 and disc 47 to rotate. The disc 45 causes the two sets of openings 46 to overlap, and the lower disc 47 twists the torsion spring 48. At the same time, the first hose 42 introduces the pigment into the liquid in the pull tube 37 to adjust the color of the liquid, making it more like real excrement and easier for the operator to observe. Secondly, when infusing or drawing liquid into the liquid chamber 35 through the water guide tube 55, the sealing ring 38 and the pull tube 37 are pushed or pulled back to move inside the inner ring 33, while the first spring 39 is squeezed. The pull tube 37 and several sets of sliders 313 pull or push one end of the rubber stying plate 310 and the L-shaped ring 314 respectively, sliding along the sliding opening 312 to realize the rubber stying. The length of the rubber stoma piece 310 protruding outward from the model body 1 can be adjusted by pulling it back to become flat or recessed, simulating the operator's handling of different stoma states. Since different patients' stomas have different protruding shapes, when the rubber stoma piece 310 protrudes outside the model body 1, pressing is applied through the textured area on the outer side of the rubber stoma piece 310, pushing the corresponding deformation rod 325 to rotate along the connecting shaft 324. The connection between the deformation rod 325 and the connecting shaft 324 pushes the locking block 317 downward, pushing the control rod 320 backward. The upper block 321 compresses the second spring 322. After rotating to a suitable angle, the compressed second spring 322 pushes the control rod 320, which in turn pushes the first movable opening 316, engaging the corresponding... In a set of slots 327, one side of the rotated deformable rod 325 is positioned, while the elastic band 326 is stretched, and the other side is squeezed to compress the rubber stoma sheet 310. According to the simulated irregular stoma, several sets of textured areas are pressed, and the rubber stoma sheet 310 is deformed and adjusted at different positions. The last lower block 323 and control rod 320 are pulled by the pull tube 37 and the slider 313. After the control rod 320 is pulled to move a certain distance, the other set of lower blocks 323 pulls the slide 312. When the control rod 320 is pulled first, the locking block 317 will move downward and unlock the deformable rod 325. Under the elastic action of the elastic band 326, the deformable rod 325 returns to its original state, which facilitates subsequent work. Through the overall multi-functional switching, the simulation variability is improved.
