[0027] Example 1
[0028] Reference Figures 1-6An enema bag includes a bag body 1 with a base plate 2 on one side. The bag body 1 is attached to the patient's body via the base plate 2. The base plate 2 can be attached to the patient's anus for connection, enabling the bag body 1 to collect feces, such as for patients with diarrhea who are unable to care for themselves or patients with severe fecal incontinence in the ICU. A connecting seat 3 is attached to the other side of the bag body 1, and a connecting tube mechanism is fitted onto the connecting seat 3. The connecting tube mechanism includes a plastic film tube 4 fixed to the connecting seat 3, which communicates with the interior of the bag body 1 and has an enema mechanism.
[0029] For the above example, those skilled in the art should know that when implementing the above technical solution, the chassis 2 can also be set to correspond to the stoma of the stoma patient, and the chassis 2 can be cut and adjusted according to the size of the stoma.
[0030] The bottom of the bag 1 is equipped with a drain port, and a valve 15 is installed on the drain port. The valve 15 is detachably connected to a negative pressure suction tube 16. The valve 15 is used to open the drain port, and the negative pressure suction tube 16 is used to connect to an existing negative pressure drainage bottle for negative pressure drainage of excrement. This ensures the cleanliness of the hospital bed, avoids direct contact between medical staff and excrement, effectively reduces air odor, keeps the patient's skin clean and dry, prevents skin irritation from excrement leading to incontinence dermatitis, and avoids fecal contamination of wounds.
[0031] The enema device includes a sleeve 5, which is coaxially and sealed to the outer end of a plastic film tube 4 away from the bag body 1. A first spray pipe 6 and a second spray pipe 7 are fixed inside the sleeve 5. The cross-sections of the first spray pipe 6 and the second spray pipe 7 are semi-circular, and they are arranged vertically together. An arc-shaped clamp 27 for holding the sleeve 5 is fixed to the side of the bag body 1. The sleeve 5 can be connected to an existing water injection pipe to perform liquid injection operations using the first spray pipe 6 and the second spray pipe 7. When not in use, the sleeve 5 can be bent and clipped onto the arc-shaped clamp 27, avoiding the occupation of excessive space.
[0032] A first spray head 8 is fixed to the end of the first spray pipe 6, and a second spray head 9 is fixed to the end of the second spray pipe 7. The second spray head 9 is annular and coaxially sleeved on the first spray pipe 6. Both the first spray head 8 and the second spray head 9 are surrounded by several spray holes. The spray holes of the first spray head 8 are inclined towards the base plate 2, and the spray holes of the second spray head 9 are inclined towards the sleeve 5. The radii of the first spray head 8, the second spray head 9, and the sleeve 5 are all the same. After water is passed through the first spray pipe 6 and the second spray pipe 7, the corresponding first spray head 8 and second spray head 9 can spray water. During an enema, the first spray head 8 and the second spray head 9 are inserted into the patient's body through the sleeve 5 to perform the water enema.
[0033] One end of the sleeve 5 opposite to the connecting seat 3 is threadedly connected to a first sealing cap 10. The first sealing cap 10 has a through hole inside, and a first graphite filter layer 11 is fixed to one end of the through hole. A sealing plate 12 is horizontally inserted into the side of the first sealing cap 10. The sealing plate 12 is connected to the first sealing cap 10 through two elastic telescopic rods 13. The elastic telescopic rod 13 includes a sleeve rod and a telescopic rod. The telescopic rod is telescopically disposed inside the sleeve rod, and a spring is provided inside the sleeve rod to connect the telescopic rod and the sleeve rod. The sealing plate 12 has a circular hole 14 corresponding to the through hole. Under the action of the elastic telescopic rods 13, the sealing plate 12 of the first sealing cap 10 keeps the through hole of the first sealing cap 10 closed. The first sealing cap 10 can block the sleeve 5. When the sleeve 5 is needed, the first sealing cap 10 can be removed. Furthermore, when the first sealing cap 10 is installed on the sleeve 5, the sealing plate 12 can be pressed and pushed when the bag body 1 is inflated, so that the round hole 14 of the sealing plate 12 is aligned with the through hole of the first sealing cap 10. At this time, the bag body 1 can be vented, and the gas is filtered through the first graphite filter layer 11, which effectively reduces the odor.
[0034] The working principle is as follows:
[0035] This device can be used for normal excrement collection operations. It can be installed at the anus of the patient to collect excrement and perform enemas, such as for diarrhea patients who cannot take care of themselves, patients with severe fecal incontinence in the ICU, and patients with ostomy bags. When an enema is required, i.e., when using the cannula 5, first remove the first sealing cap 10. Then connect the cannula 5 to the existing water injection pipe. Next, insert the first spray head 8 and the second spray head 9 into the middle of the base plate 2 through the cannula 5, and finally slowly insert it into the patient's body 7-10 cm. After that, the water enema operation can be performed by injecting no more than 500 ml of 0.9% saline or 0.5%-1% soap water into the first spray pipe 6 and the second spray pipe 7. The liquid is retained in the body for about 5-10 minutes. After removing the cannula 5, defecation will be induced, and the stool will flow into the bag 1. Then, the valve 15 can be opened. The negative pressure suction pipe 16 is pre-connected to the existing negative pressure drainage bottle for negative pressure drainage of excrement. The above operation can ensure the cleanliness of the bed, avoid medical staff's direct contact with excrement, effectively reduce air odor, and keep the patient's skin clean and dry, avoiding skin irritation from excrement and the formation of incontinence dermatitis.
[0036] During the enema, since several nozzles of the second spray head 9 are inclined towards the cannula 5, the patient can also be cleaned during the enema, i.e., rinsed and cleaned from the inside out. After the enema is completed, the cannula 5 can be removed, and the first spray head 8 and the second spray head 9 can be used for spraying. Since several nozzles of the first spray head 8 are inclined towards the base plate 2, and several nozzles of the second spray head 9 are inclined towards the cannula 5, the front and rear inner walls of the bag body 1 can be rinsed, achieving a uniform rinsing effect.
[0037] Meanwhile, when the sleeve 5 is not in use, a first sealing cap 10 needs to be installed, and the sleeve 5 can be bent and snapped onto the arc-shaped clip 27 to avoid occupying too much space. In the case of the bag body 1 being inflated, the sealing plate 12 can be pressed and pushed so that the round hole 14 of the sealing plate 12 is aligned with the through hole of the first sealing cap 10. At this time, the bag body 1 can be deflated, and the gas is filtered through the first graphite filter layer 11, which effectively reduces the odor.
[0038] Example 2
[0039] Reference Figure 7 and Figure 8
[0040] The connecting tube mechanism also includes a threaded seat 17 disposed on the connecting seat 3. The threaded seat 17 has a slot communicating with the bag body 1, and a plastic film is coaxially disposed in the slot. The plastic film has a cross hole, and the cross hole of the plastic film can only be exposed when pressure is applied, so the plastic film has a certain liquid sealing effect. The threaded seat 17 can be threadedly connected to a first knob 18, and the first knob 18 is coaxially fixedly connected to an enema tube 19, which can be set to insert the enema tube 19 into the patient's body. That is, the enema tube 19 passes through the slot of the threaded seat 17, squeezes through the cross hole of the plastic film, extends into the inside of the bag body 1, and finally is inserted into the patient's body from the middle of the base 2, while the first knob 18 is threadedly and sealed and tightened on the threaded seat 17. The threaded seat 17 is threadedly connected to a second knob 20, which is coaxially fixedly connected to a nozzle tube 21. The nozzle tube 21 can be inserted into the bag body 1, that is, the nozzle tube 21 passes through the slot of the threaded seat 17 and is squeezed through the cross hole of the plastic film, extending into the interior of the bag body 1. The second knob 20 is threadedly and tightly tightened onto the threaded seat 17. The threaded seat 17 is also threadedly connected to a second sealing cap 22, which has a second graphite filter layer 23. After the second sealing cap 22 is installed on the threaded seat 17, the second graphite filter layer 23 can filter the gas.
[0041] One end of the enema tube 19 passes through the first knob 18 and is fitted with a first sealing plug 24. One end of the nozzle tube 21 passes through the second knob 20 and is fitted with a second sealing plug 25. The first sealing plug 24 and the second sealing plug 25 serve to seal the tube. Both the enema tube 19 and the nozzle tube 21 can be connected to existing injection tubes. The other end of the nozzle tube 21 is connected to a spherical spray head 26. The spherical spray head 26 has several evenly distributed spray holes, which can achieve a uniform and comprehensive spray rinsing effect on the inside of the bag 1.
[0042] The working principle is as follows:
[0043] During enema, the enema tube 19 is installed, passed through the slot of the threaded seat 17, and squeezed through the cross hole of the plastic film to extend into the bag body 1. Finally, it is slowly inserted into the patient's body from the middle of the base 2. The first knob 18 is then screwed into the threaded seat 17 for a threaded seal. Afterward, the enema tube 19 is connected to the existing injection tube to perform the enema operation. After the enema and drainage of stool, the enema tube 19 is removed, and the nozzle tube 21 is installed. The nozzle tube 21 is passed through the slot of the threaded seat 17, and squeezed through the cross hole of the plastic film to extend into the bag body 1. The second knob 20 is then screwed into the threaded seat 17 for a threaded seal. Afterward, the nozzle tube 21 is connected to the existing injection tube, allowing the spherical spray head 26 to provide a uniform and comprehensive spray rinsing effect to the inside of the bag body 1.
[0044] After completing the above operations, install the second sealing cap 22. When the bag body 1 inflates, press the bag body 1; the cross holes of the plastic film will be compressed and exposed, allowing the gas to be filtered through the second graphite filter layer 23 before being discharged. The installation of the second sealing cap 22 and the threaded seat 17 effectively reduces the space occupied.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
