Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a Chinese medicine retention enema device for patients with intestinal stoma. Background Art

[0002] Chinese medicine retention enema has significant efficacy in the treatment of radiation enteritis and has few side effects. Chinese medicine retention enema is generally injected into the anus through an anal tube. For some special patients with colostomy, if traditional enema is used to treat colostomy, the following problems will occur: ① Because the diameter of the anal tube is relatively thick and not soft enough, the intubation is irritating, which will increase the patient's pain and is not suitable for colostomy enema. Some scholars have also proposed the use of anal tube substitutes (disposable urinary catheters or disposable suction tubes). For example, scholar Zhang Feng proposed "The Application of Suction Tubes in Enema" and scholar Chen Hui proposed "Research on the Application of 50ml Syringe Connected to Disposable Urinary Catheter Small Dose Retention Enema". Although the above scheme can solve the problems of tube diameter and softness, the cost is relatively high; and it is not easy to control the enema speed and pressure by push injection. ② When patients with colostomy receive enema, they need to remove the stoma bag and perform open enema. Because the stoma itself has no anal sphincter, the enema liquid and feces will flow out at any time during the enema, causing the patient to feel uncomfortable. The nurse should always be careful not to contaminate the bed unit and incision dressing. At the same time, the odor is strong, which affects the patients in the same ward and causes the patient to have an inferiority complex.

[0003] Therefore, further research is needed on how to improve enema devices for these special patients with colostomy in terms of alleviating patient pain, improving patient comfort, reducing pollution, reducing nursing pressure, and reducing costs. Utility Model Content

[0043] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0044] Embodiment 1:

[0045] like Figure 1 - Fig.12 As shown, this embodiment proposes a Chinese medicine retention enema device for patients with colostomy, which mainly includes a liquid filling component and an anti-fouling component. The following is a further explanation of these two parts:

[0046] Part I:

[0047] The liquid filling assembly includes an enema bag 11 and an infusion tube 8 connected to the enema bag 11, and the infusion tube 8 is provided with a Maofei dropper 10 and a flow regulator 9; the infusion tube 8 is an ordinary disposable infusion set, the needle part of the infusion set is removed, and the liquid filter is removed with sterile scissors, and the tail end of the infusion set can be cut into a round and blunt shape with sterile scissors before use to reduce stimulation, and the other parts are retained. Regarding the enema bag 11, a transparent and scaled infusion bag is used in this embodiment, and of course an infusion bottle can also be used. In this embodiment, an infusion bag is preferably used, which is transparent and scaled, with a capacity of 500ml, 250ml, 100ml, and 50ml. If 300ml or 200ml doses need to be filled, it is still accurate, and the remaining amount is easy to observe; and one side of the infusion bag has been cut open near the top corner, which is convenient for measuring the temperature of the liquid medicine and adding the liquid medicine at any time. Because the opening is on the side of the infusion bag and is covered by the top corner, the liquid medicine is not polluted by dust in the air. The infusion set is transparent, and has a Maofei dropper 10 and a flow regulator 9, so that the infusion speed and pressure are easy to control.

[0048] In this embodiment, the bottom of the bag body 1 is provided with a sewage outlet, and a sealing clip 4 is provided at the sewage outlet.

[0049] Part II:

[0050] The anti-fouling component includes an ostomy bag, which includes a bag body 1 and a chassis 2; the chassis 2 is provided with a through hole 3, the size of which can be cut by the user; a mounting hole 5 is also provided on the bag body 1 corresponding to the through hole 3, and a sealing member 6 is provided in the mounting hole 5, and the sealing member 6 is connected to the bag body 1; an insertion channel for inserting an infusion tube 8 is provided in the sealing member 6, and the end of the infusion tube 8 enters the intestinal stoma through the insertion channel. The mounting hole 5 can be formed by cutting with sterilized scissors or by a dedicated puncher. The sealing member 6 is a split modular structure, which can be detachably connected. When installation is required, the sealing member 6 is arranged in the mounting hole 5, and a communication channel between the inside of the bag body 1 and the outside of the bag body 1 can be constructed by using the insertion channel of the sealing member 6, so as to facilitate the insertion of the enema pipeline.

[0051] In this embodiment, the sealing member 6 adopts the following structure:

[0052] The seal 6 includes a fixed pressure plate 65, and a sleeve 62 is coaxially fixedly connected to one side of the fixed pressure plate 65; the sleeve 62 can be adapted and plugged with the mounting hole 5, and when in use, the sleeve 62 can be inserted into the mounting hole 5; the sleeve 62 is threadedly connected with a detachable movable pressure plate 61, and the movable pressure plate 61 and the fixed pressure plate 65 clamp and fix the bag wall of the bag body 1, and the two can be used to achieve assembly with the bag body 1; the fixed pressure plate 65 and the movable pressure plate 61 are both annular structures, and a second rubber ring 66 is provided inside the fixed pressure plate 65, and the second rubber ring 66 can be adapted and plugged with the infusion tube 8 or other enema pipelines to form an inner sealing layer. The fixed pressure plate 65 is provided with a groove along the inner wall of the hole in the center for installing the second rubber ring 66 to facilitate positioning and installation.

[0053] As a feasible embodiment, weight-reducing holes are provided on the surface of the movable pressure plate 61 and / or the fixed pressure plate 65 to reduce weight, lower the load, and improve the comfort of the patient when wearing it.

[0054] Considering that the infusion tube 8 needs to be pulled out after the enema is completed, the internal insertion channel of the seal 6 cannot be sealed, and it can only be sealed with other items, such as using an empty stopper bottle to plug into the seal 6 to achieve the closure of the insertion channel to prevent the enema liquid or feces from splashing or flowing out. Although this method is feasible, it is still not convenient enough. For this reason, further optimization is made:

[0055] A flexible tube 7 for guiding and sealing is also sleeved on the infusion tube 8. The diameter of the flexible tube 7 is larger than that of the infusion tube 8. One end of the flexible tube 7 penetrates the insertion channel of the seal 6 and extends into the intestinal stoma, and the other end is arranged outside the seal 6; a sealing structure is formed between the flexible tube 7 and the insertion channel; the infusion tube 8 enters the intestinal stoma through the guiding effect of the flexible tube 7, and at this time, the second rubber ring 66 cooperates with the flexible tube 7 to seal. In this embodiment, the flexible tube 7 is a silicone tube or a latex tube. When in use, after expanding the stoma with the index finger, one end of the flexible tube 7 is placed in the stoma, and the other end passes through the insertion channel of the seal 6 and extends to the outside of the seal 6. In this way, when enema is performed, the cavity inside the flexible tube 7 is used as a guiding channel, and it can be conveniently and smoothly inserted into the stoma, and the flexible tube 7 also acts as a protective sleeve to reduce the stimulation to the inner wall of the stoma when the infusion tube 8 is inserted.

[0056] Embodiment 2:

[0057] Continue to refer to the attached Figure 1 - Fig.12 Considering that the seal close to the second rubber ring 66 may be not tightly sealed, and there is a risk of leakage of enema liquid or feces, further optimization is made on the basis of the above embodiment:

[0058] In this embodiment, one end of the sleeve 62 is also threadedly connected with a gland 63, and a center hole is set in the center of the gland 63. The center hole is larger than the outer diameter of the flexible tube 7 to facilitate the insertion of the flexible tube 7; the end of the sleeve 62 is fitted with a first rubber ring 64. When the gland 63 is tightened on the sleeve 62, the first rubber ring 64 is squeezed and deformed, so that the inner wall of the first rubber ring 64 is tightly fitted with the outer wall of the flexible tube 7 to form an outer sealing layer; the inner sealing layer and the outer sealing layer together form a sealing structure, so that a double-layer sealing system is constructed, which can effectively prevent the outflow of enema liquid or feces and the dissipation of odor. In addition, by screwing the gland 63 to a certain degree of tightness, different deformation amounts of the first rubber ring 64 can be achieved. The tighter the screwing, the greater the deformation amount of the first rubber ring 64, which not only achieves a high seal of the flexible tube 7, but also increases the resistance and plays a certain clamping and positioning role. The second rubber ring 66 has less resistance to the flexible tube 7 and lower sealing, which makes it easier to insert the tube. When the tube is inserted, the pressure cap 63 is screwed on, and the first rubber ring 64 is squeezed and deformed on the flexible tube 7 by tightening the pressure cap 63, so as to achieve a close fit. While the first rubber ring 64 achieves high sealing, it also has greater resistance to the movement of the flexible tube 7, which is equivalent to achieving a clamping and positioning function.

[0059] Directions:

[0060] 1. Material preparation: disposable infusion set, flexible tube 7, clamps, infusion bags, sterilized scissors, Chinese medicine enema solution (prepare according to doctor's orders), liquid paraffin, pre-processed seals 6, etc.

[0061] 2. Production and operation methods:

[0062] 2.1. Use sterile scissors to cut a 3-4cm hole near the top corner of the empty infusion bag, and pour the enema solution into the empty infusion bag from here. Remove the needle part of the infusion set, and use sterile scissors to remove the liquid filter. The tail end of the infusion set can be cut blunt with sterile scissors before use to reduce irritation, and the other parts can be retained.

[0063] 2.2. Open a hole at a suitable position of the bag body 1 of the ostomy bag to form the installation hole 5 and then install the seal 6. During installation, the fixed chuck and the sleeve 62 enter the bag body 1 from the through hole 3 of the bottom plate 2, the sleeve 62 is inserted into the installation hole 5, and the movable chuck is screwed on to clamp the bag wall of the bag body 1 to ensure sealing.

[0064] 2.3. In order to obtain the appropriate temperature of the liquid medicine, a sterilized thermometer can be inserted into the opening of the infusion bag to measure the temperature of the enema liquid medicine, which is generally controlled at around 38°C.

[0065] 2.4. Prepare all the necessary supplies and bring them to the bedside, and use a screen to protect the patient's privacy; explain the purpose and method of enema to the patient's family and obtain their cooperation.

[0066] 2.5 Hang the infusion bag filled with enema solution on the lifting infusion stand, insert the disposable infusion set into the bottle stopper, and close the infusion set after exhausting all the air.

[0067] 2.6. Place a disposable mattress on the bed, wear disposable gloves, lubricate the end of the infusion tube 8, expand the stoma with your index finger, place one end of the flexible tube 7 in the stoma, and after the other end passes through the seal 6, stick the stoma bag to the stoma; slowly insert the infusion set into the stoma through the inner cavity of the flexible tube 7. If the insertion is not smooth, loosen the regulator and use the guiding effect of the liquid to rotate left and right to slowly insert. If the dripping is not smooth, increase the height of the enema bag 11 and adjust the insertion depth. During the enema process, pay attention to observe whether the patient has palpitations, abdominal pain and other discomforts. If there is any abnormality, report it to the doctor in time.

[0068] 2.7. After the enema is completed, the infusion tube 8 is pulled out, and the flexible tube 7 is still placed in the stoma. To prevent the enema liquid from overflowing, an empty stopper bottle can be inserted into the other end of the flexible tube 7 to block the tube opening. After the enema is completed, it should be kept for more than 1 hour. It should be noted that the flexible tube 7 can also be clamped by a clip to achieve the blocking of the tube opening.

[0069] Application results:

[0070] Based on the actual situation, this scheme has developed a closed enema structure for the enema needs of patients with colostomy. By simply modifying the existing ostomy bag and configuring an adaptive seal 6, it is convenient to insert the enema pipeline, and can achieve effective sealing between the enema pipeline and the seal 6 and the ostomy bag, which can prevent the enema liquid or feces from spraying out and avoid making the patient feel uncomfortable. The closed structure can reduce the odor and reduce the impact on patients in the same ward. The ostomy bag has the functions of buffering and storing feces, and establishes the functions of secondary leakage prevention and feces connection, which can effectively avoid environmental pollution and related secondary cross-infection. In addition, the infusion tube 8 is used in this scheme instead of the anal tube. Compared with the suction tube or the urinary catheter, it is more convenient to obtain materials, economical and low-cost; and the diameter of the infusion tube 8 is thin and soft, and the irritation and damage are less than the traditional enema method, which can reduce the patient's discomfort.

[0071] Embodiment three:

[0072] Reference Fig.13 - Fig.15 On the basis of the first or second embodiment, the other side of the fixed pressure plate 65 is further connected to a plug 12, which is in the shape of a nipple; a cross opening 121 is provided at the head of the plug 12; the plug 12 can be inserted into the colostomy to form a blocking structure after the enema is completed. In this embodiment, the plug 12 is made of silicone. The plug 12 can be made by cutting a nipple. The plug 12 can cover the colostomy to avoid leakage and contamination caused by the backflow of the enema liquid, thereby improving the enema effect and reducing the workload of the nursing staff.

[0073] When the infusion tube 8 is inserted, the cross opening 121 is stretched open, and the infusion tube 8 can smoothly pass through the head of the plug 12; when the infusion tube 8 is pulled out, the cross opening 121 is closed to form a closed structure, which plays a shielding role.

[0074] The method of using this solution is the same as above. Before enema, just insert the plug 12 into the enterostomy. The plug 12 can serve as a guide for the flexible tube 7. After the infusion tube 8 is removed, the head of the plug 12 closes automatically to play a blocking role.

[0075] The above scheme has the following advantages:

[0076] ①Simple operation, convenient and quick to use.

[0077] ②The ostomy bag is clean and transparent, making it easy to observe the stoma condition.

[0078] ③ All discharges are in the ostomy bag, with little odor, avoiding pollution, improving patient comfort, maintaining the hygiene of the ward environment, and reducing the workload for nurses and their families.

[0079] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
