Description

Technical Field

[0001] This utility model relates to the field of medical care device technology, and in particular to an enterostomy dilation device. Background Technology

[0002] An enterostomy is an artificial opening made in the abdominal wall by a surgeon to treat certain intestinal diseases (such as rectal cancer, ulcerative colitis, etc.). A section of the intestine is pulled out of the opening, turned inside out, and sutured to the abdominal wall, thus forming an enterostomy. Its function is to replace the original perineum and anus to perform defecation.

[0003] In wards today, for patients who have undergone enterostomy surgery, medical staff will attach an ostomy bag to the stoma to collect the patient's excrement. This bag needs to be changed frequently. As the granulation tissue and scar tissue shrink, the initially appropriately sized stoma gradually narrows and worsens. Therefore, the enterostomy needs to be observed when changing the ostomy bag. For narrow enterostomies, medical staff need to manually dilate them. However, the following problems arise during this process:

[0004] 1. Enterostomy: Because it is a condition that is different from that of normal people, patients regard it as their own privacy. After medical staff change the pockets, they also have to insert their fingers into the enterostomy to widen it. The above behavior makes patients feel resistant, making it difficult to carry out the care work. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide an enterostomy dilation device, which aims to solve the problem of patients' psychological resistance to medical staff inserting their hands into the enterostomy to dilate the enterostomy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An enterostomy dilation device includes a base, an mounting ring fixed to the periphery of the base, a cover disposed on the mounting ring, a mounting assembly disposed on the lower side of the cover, and an dilation assembly movably disposed on the cover for opening the enterostomy.

[0008] The expansion assembly includes a height-adjusting sleeve that runs through the central axis of the casing and is movable along the height direction, a connecting plate that is detachably located at the lower end of the height-adjusting sleeve, several support rods fixed below the connecting plate, a support plate located below the connecting plate and fixedly connected to the lower ends of each support rod, an expansion airbag fixed between the support plate and the connecting plate, and a push rod that is movable along the height direction at the central axis inside the height-adjusting sleeve and is used to expand the expansion airbag in all directions to open the enterostomy.

[0009] The cover is provided with a threaded sleeve along the height direction, and the outer wall of the height adjustment sleeve is threadedly connected to the inner wall of the threaded sleeve.

[0010] The lower part of the push rod is provided through the connecting plate, and the upper side wall of the push rod is provided with a limiting track. The upper end of the height adjusting sleeve is fixed with a limiting ring that is embedded in the limiting track and can move.

[0011] More preferably, a connecting sleeve is fixedly provided on the upper edge of the connecting plate, and the connecting sleeve is threadedly connected to the lower end of the height adjusting sleeve.

[0012] More preferably, the upper end of the height adjusting sleeve is fixedly provided with a rotating handle, and the upper end of the push rod is fixedly provided with a pressing handle.

[0013] More preferably, a reset spring for moving the push rod upward is fixed between the upper side of the limiting ring and the upper side of the inner wall of the limiting track.

[0014] More preferably, a pair of mounting grooves are symmetrically provided on the left and right sides of the bottom of the mounting ring channel along the central axis of the mounting ring channel. The mounting assembly includes a pair of anti-slip members respectively provided on the lower sides of the cover and passing through the mounting ring channel along the corresponding mounting grooves, and a pair of rotating columns respectively rotatably provided on the upper side of each anti-slip member and fixedly connected to the bottom of the cover.

[0015] More preferably, the bottom of the installation ring is provided with a plurality of limiting grooves arranged at intervals along the circumference, and the bottom of the cover is provided with a plurality of limiting posts embedded in the corresponding limiting grooves.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model allows patients to perform stoma dilation themselves without the assistance of medical staff after the stoma bag installed on the base is removed, cleaned, and disinfected. The patient then rotates the height adjustment sleeve, causing the connecting plate at the lower end to move towards the inside of the stoma until the expansion balloon, fixed below the connecting plate, is fully inserted into the stoma. The patient then pushes down on the push rod, causing it to slide downwards and press against and squeeze the center of the expansion balloon. This causes the gas in the center of the expansion balloon to flow outwards, resulting in the balloon expanding outwards and pushing the inner wall of the stoma outwards, thus dilating the stoma. This allows patients to perform stoma dilation themselves without the assistance of medical staff, thereby resolving the patient's psychological resistance to stoma dilation by medical personnel.

[0018] 2. This utility model uses a threaded connection between a connecting sleeve and a height adjusting sleeve, so that a new expansion balloon can be fixed to the connecting plate each time the colostomy is dilated, thereby preventing the reused expansion balloon from causing bacterial infection of the colostomy.

[0019] 3. When installing the cover, the anti-slip component is aligned with the mounting groove, and then the cover is pushed down so that the lower part of the cover is embedded in the mounting ring, and each limiting post is embedded in the corresponding limiting groove. Then the anti-slip component is rotated so that the upper side of the anti-slip component abuts against the bottom of the outer wall of the mounting ring, thereby restricting the movement of the cover and achieving quick installation.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 and Figure 2 As shown, an enterostomy dilation device of this embodiment includes a base 1, an installation ring 2 fixed to the periphery of the base 1, a cover 3 disposed on the installation ring 2, an installation component 4 disposed on the lower side of the cover 3, and an dilation component 5 movably disposed on the cover 3 for dilating the enterostomy.

[0028] The expansion assembly 5 includes a height adjusting sleeve 51 that passes through the central axis of the housing 3 and is movable along the height direction; a connecting plate 52 that is detachably disposed at the lower end of the height adjusting sleeve 51; a number of support rods 53 fixed below the connecting plate 52; a support plate 55 disposed below the connecting plate 52 and fixedly connected to the lower ends of each support rod 53; an expansion airbag 56 fixed between the support plate 55 and the connecting plate 52; and a push rod 57 that is movable along the height direction at the central axis inside the height adjusting sleeve 51 and is used to expand the expansion airbag 56 to the surrounding area to open the enterostomy.

[0029] A threaded sleeve 6 is provided inside the cover 3 along the height direction, and the outer wall of the height adjusting sleeve 51 is threadedly connected to the inner wall of the threaded sleeve 6.

[0030] The lower part of the push rod 57 is set through the connecting plate 52, and the upper side wall of the push rod 57 is provided with a limiting rail 7. The upper end of the height adjusting sleeve 51 is fixed with a limiting ring 8 that is embedded in the limiting rail 7.

[0031] When using this product, the cover 3 is installed in the installation ring 2. Then, the patient adjusts the position of the height adjustment sleeve 51, which causes the lower expansion balloon 56 to slide down to the appropriate position. Then, the patient presses the push rod 57, causing the lower end of the push rod 57 to abut against the middle of the expansion balloon 56 and causing the expansion balloon 56 to expand in all directions. This pushes the inner wall of the enterostomy outward, thus achieving the effect of dilating the enterostomy and solving the patient's psychological resistance to medical staff dilating the enterostomy.

[0032] like Figure 2 As shown, a connecting sleeve 9 is fixedly provided on the upper edge of the connecting plate 52, and the connecting sleeve 9 is threadedly connected to the lower end of the height adjusting sleeve 51.

[0033] When using this product, each time expansion care is needed, rotate the connecting sleeve 9 to remove the connecting plate 52, and then replace it with a new one.

[0034] like Figure 1 and Figure 2 As shown, a rotating handle 10 is fixedly provided at the upper end of the height adjusting sleeve 51, and a pressing handle 11 is fixedly provided at the upper end of the push rod 57.

[0035] When using this product, rotating the handle 10 causes the height adjustment sleeve 51 to move along the thread direction, which makes it easy for the patient to adjust the depth of the expansion balloon 56 inserted into the enterostomy. When pressing the push rod 57, hook the handle 10 with your fingers and press the handle 11 downward with your palm, thereby causing the push rod 57 to slide downward, thus preventing pressure from being applied to the base 1 during the pressing process, which would cause discomfort to the patient's abdomen.

[0036] like Figure 1 and Figure 2As shown, a reset spring 12 for moving the push rod 57 upward is fixed between the upper side of the limiting ring 8 and the upper side of the inner wall of the limiting track 7.

[0037] When using this product, after pressing to the bottom, release the hand holding the pressing handle 11. Under the reset thrust of the return spring 12, the push rod 57 moves upward, causing the push rod 57 to move upward and disengage from the contact point with the dilator 56. This causes the dilator 56 to be squeezed inward by the enterostomy, thus restoring the shape of the dilator 56. Repeating the pressing and releasing operation of the pressing handle 11 achieves the effect of repeatedly dilating the enterostomy.

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a pair of mounting grooves 13 are symmetrically arranged on the left and right sides of the bottom of the mounting ring 2 along the central axis of the mounting ring 2. The mounting assembly 4 includes a pair of anti-slip parts 41 respectively located on the lower sides of the cover 3 and passing through the mounting ring 2 along the corresponding mounting grooves 13, and a pair of rotating columns 42 respectively rotatably located on the upper side of each anti-slip part 41 and fixedly connected to the bottom of the cover 3.

[0039] When using this product, align the bottom of the cover 3 with the mounting ring 2, and rotate the anti-slip parts 41 on both sides until they are aligned with the mounting groove 13. Then, insert the lower part of the cover 3 into the mounting ring 2, with the anti-slip parts 41 extending out of the mounting groove 13. Then rotate the anti-slip parts 41 to make the upper side of the anti-slip parts 41 abut against the bottom of the outer wall of the mounting ring 2, thereby completing the installation.

[0040] like Figure 3 and Figure 4 As shown, the bottom of the installation ring 2 is provided with several limiting grooves 14 arranged circumferentially, and the bottom of the cover 3 is provided with several limiting posts 15 embedded in the corresponding limiting grooves 14.

[0041] When using this product, each limiting post 15 is aligned with its corresponding limiting groove 14 for installation. This ensures that after the limiting post 15 is embedded in the limiting groove 14, the cover 3 is restricted by the limiting groove 14 and cannot move in the circumferential direction, thus achieving a stable installation effect.

[0042] The working principle of this device is as follows:

[0043] Step 1: Medical staff remove the stoma bag from the base 1 and disinfect and clean the enterostomy area. The patient aligns the bottom of the cover 3 with the installation ring 2, with each limiting post 15 at the bottom of the cover 3 corresponding to each limiting groove 14. The anti-slip parts 41 on both sides are rotated until they are aligned with the installation groove 13. Then, the lower part of the cover 3 is inserted into the installation ring 2, so that each limiting post 15 is inserted into each limiting groove 14, and the anti-slip part 41 extends out of the installation groove 13. Then, the anti-slip part 41 is rotated to make the upper side of the anti-slip part 41 abut against the bottom of the outer wall of the installation ring 2, thus completing the installation.

[0044] Step 2: The patient rotates the handle 10, which causes the height adjustment sleeve 51 to rotate, thereby moving along the thread direction of the threaded connection with the threaded sleeve 6. This causes the height adjustment sleeve 51 to move down synchronously with the connecting plate 52 connected to it, until the expansion balloon 56 below the connecting plate 52 moves into the enterostomy.

[0045] Step 3: At this time, the patient hooks the rotating handle 10 with their fingers and presses the handle 11 downwards with their palm, thereby causing the push rod 57 to slide downwards. This causes the lower end of the push rod 57 to pass through the connecting plate 52 and abut against the middle of the expansion balloon 56, squeezing the middle of the expansion balloon 56. This causes the air in the middle of the expansion balloon 56 to flow to all sides, causing the expansion balloon 56 to deform and expand around itself, adhering to the side wall of the enterostomy and pushing the side wall of the enterostomy away from the central axis of the connecting plate 52, achieving the expansion effect. After pressing to the bottom, the patient releases the hand pressing the handle 11. Under the return thrust of the return spring 12, the push rod 57 moves upwards, causing the push rod 57 to move upwards and disengage from the abutment of the expansion balloon 56. This causes the expansion balloon 56 to be squeezed inwards by the enterostomy, and the expansion balloon 56 to deform and return to its original shape. Repeating the pressing and releasing of the handle 11 achieves the effect of repeatedly expanding the enterostomy.

[0046] Step 4: After the dilation care is completed, rotate the anti-slip part 41 to align with the installation slot 13, and then remove the cover 3 outward. After cleaning, the medical staff will install a new stoma bag and separate the connecting sleeve 9 from the height adjustment sleeve 51 by rotating the connecting sleeve 9. Replace the connecting sleeve 9 with a new dilation airbag 56 for the next care.

[0047] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
