Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a stoma device. Background Art
[0002] Globally, bladder cancer ranks 10th among malignant tumors in incidence, 6th among men and just after 10th among women, with the 12th highest mortality rate. In my country, approximately 92,000 new cases of bladder cancer and 43,000 deaths are expected in 2022. Bladder cancer ranks 8th among malignant tumors in men and just after 10th among women. In my country, approximately 42,900 deaths are expected in 2022, ranking 14th among systemic malignancies. Approximately 32,400 deaths will occur in men, ranking 11th, and approximately 10,500 deaths will occur in women, ranking 16th. For muscle-invasive or high-grade bladder cancer, radical cystectomy remains the preferred treatment option. Following bladder removal, patients may require urinary diversion. The classic and safest surgical approach currently used is ileal conduit surgery, which involves harvesting the terminal ileum, anastomosing the proximal end to the ureter, and creating an abdominal stoma distally to create a bladder replacement, requiring a lifelong urine collection bag.
[0003] Early postoperative complications can reach 48%, and contamination of urinary diversion and stoma sites can cause retrograde infection, including urinary tract infection, pyelonephritis, etc.; with the increase of postoperative follow-up time, complications increase accordingly, with 5-year complications being 45% and 15-year complications reaching 94%, among which the incidence of upper urinary tract hydrops and urinary tract urolithiasis in patients reaches 50% and 38% respectively. The current methods to combat such infections mainly rely on systemic medication such as oral or injection. Utility Model Content

[0036] The following further describes the present utility model in detail with reference to the embodiments in the drawings.
[0037] Referring to Figure 1 , after a stoma operation, a base 100 is installed at the intestinal substitute bladder stoma of the patient. An opening 101 is provided on the base 100. Excreta such as urine produced by the patient's intestine is discharged through the opening 101 on the base 100. The drug carrier rack is installed on the base 100 and extends towards the inside of the stoma, so as to penetrate the drugs on the drug carrier rack into the intestinal substitute bladder at the stoma of the patient, and continuously administer drugs to the substitute bladder of the patient by using the drugs in the drug carrier rack, thereby realizing the functions of continuous antibacterial and sterilization. By setting the drug carrier rack, the problem of retrograde infection of the intestine at the stoma after the existing operation is effectively solved.
[0038] In this embodiment, the drug carrier rack can be integrally formed with the base 100 (not shown in the figure), or can be separately provided from the base 100. When separately provided, it is convenient to separate the drug carrier rack from the base 100 to replace the drug carrier rack or disassemble the drug carrier rack. The following takes the separately provided method as an example to describe the specific structure of the drug carrier rack in detail:
[0039] In this embodiment, the drug carrier includes a drug delivery part 200 extending towards the patient's stoma, a connecting part 300 detachably connecting the drug delivery part 200 and the base 100. The drug delivery part 200 is used to set drugs, and its shape can be strip-shaped, columnar, sheet-shaped or other shapes. Limited by the size of the stoma at the patient's stoma, in this embodiment, the drug delivery part 200 is preferably cylindrical. Its upper end is connected to the connecting part 300, and its lower end carries drugs to extend into the intestinal bladder.
[0040] In this embodiment, the drug delivery part 200 and the connecting part 300 can be integrally formed or movably arranged. The structure of the connecting part 300 will be described in detail below:
[0041] Refer to Figure 1 , as the first embodiment of the connecting part 300, the connecting part 300 includes at least one support rod 310 circumferentially arranged around the upper end of the drug delivery part 200. The upper end of the support rod 310 is hinged to the upper end of the drug delivery part 200, and its lower end is provided with a plug 311. The support rod 310 can be inserted into the annular groove 110 through the plug 311. The plug 311 and the annular groove 110 can be inserted in such a way that the plug 311 is made of an elastic and compressible material. By using the interference fit formed between the plug 311 and the inner wall of the annular groove 110, the support rod 310 can be detachably connected to the base 100.
[0042] In this embodiment, the plug 311 can be made of rubber or silica gel material, and its shape can be mushroom-shaped or other shapes. As long as it can form a clamping fit with the annular groove 110 to detachably install the connecting part 300 on the base 100. Of course, it can also be made of non-elastic material. For example, sockets are provided at the bottom of the annular groove 110 or on the base 100, and the plug 311 is directly inserted into the sockets, and then the connecting part 300 and the base 100 can be connected and fixed.
[0043] In this embodiment, the upper end of the support rod 310 is hinged to the upper end of the drug delivery part 200. The advantage of this is that the support rod 310 can rotate along its hinge with the drug delivery part 200, so that multiple support rods 310 can be opened in an umbrella shape or folded together with the drug delivery part 200, which is convenient for the storage of the entire drug carrier.
[0044] Refer to Figure 2 , as the second embodiment of the connecting part 300, the connecting part 300 can be a connecting belt 380. One end of the connecting belt 380 is fixed to the upper end of the drug delivery part 200. The connecting belt 380 has a certain flexibility, and along the length direction of the connecting belt 380, there are several clamping heads that form a snap fit with the annular groove 110 of the base 100. After the clamping heads are snapped with the annular groove 110 of the base 100, the drug delivery part 200 is fixed and positioned on the base 100.
[0045] In this embodiment, in order to facilitate adjusting the insertion depth of the drug delivery part 200 into the stoma of the patient, a pre-breaking groove 381 can be provided between adjacent chucks. In this way, according to the depth requirement of the drug delivery part 200 inserted into the stoma, the connecting belt 380 can be intercepted to a predetermined length through the pre-breaking groove 381, so as to meet the adjustment of the drug delivery depth of the drug delivery part 200 and the stoma, and to solve the problem that the drug delivery part 200 cannot accurately deliver drugs when the intestinal infection depth at the stoma is too large.
[0046] Preferably, in the two embodiments of the above-mentioned connecting part 300, the number of the support rods 310 and the connecting belts 380 is preferably three. The three support rods 310 or the connecting belts 380 are arranged around the drug delivery part 200 at intervals. In this way, after the connecting part 300 is connected to the base 100, the structural stability of the drug delivery part 200 arranged at the stoma can be improved.
[0047] Refer to Figure 4 , as the third embodiment of the connecting part 300, the connecting part 300 is a ring 352 arranged at the upper end of the drug delivery part 200. The inside of the ring 352 is hollow, and its bottom is provided with an opening. The inner diameter of the opening forms a clearance fit or an interference fit with the outer periphery of the base 100. The drug delivery part 200 is located at the center of the ring 352. The inner wall of the ring 352 and the drug delivery part 200 can be connected through a plurality of connecting rods 351, so that the drug delivery part 200 and the connecting part 300 are integrally formed. When the drug carrier needs to be installed at the stoma of the patient, the entire ring 352 can be covered on the base 100, so that the extension part can be inserted into the stoma of the patient.
[0048] In this embodiment, preferably, in order to avoid the influence of the setting of the connecting rod 351 on the installation of the ostomy bag on the annular groove 110 of the base 100, a recessed part can be provided on the connecting rod 351 at the position corresponding to the annular groove 110. The inner wall of the annular groove 110 is attached through the recessed part to avoid the connecting rod 351 from hindering the connection between the ostomy bag and the base 100.
[0049] Refer to Figure 5 , as the fourth embodiment of the connecting part 300, different from the third embodiment, the diameter of the ring 352 matches the diameter of the annular groove 110, and the bottom of the ring 352 extends downward by a certain distance, so that the ring 352 can be directly buckled into the annular groove 110 to realize the connection between the drug carrier part and the base 100.
[0050] In this embodiment, the thickness of the ring 352 can be less than the depth of the annular groove 110, so as to avoid affecting the setting of the ostomy bag when the patient wears the ostomy bag.
[0051] Based on the third and fourth embodiments of the above-mentioned connecting portion 300, in the above two embodiments, the connecting portion 300 and the administering portion 200 are integrally formed. Of course, it is conceivable that a slot can be provided at the end of the administering portion 200, and then a buckle can be provided at the end of the connecting rod. In this way, the connecting portion 300 and the administering portion 200 can be detachably separated by cooperating with the buckle and the slot bracket. Of course, in this embodiment, the ring 352 and the ring 352 and the administering portion 200 can also be detachably separated by bolts, glue or other means, which will not be elaborated here.
[0052] In this embodiment, the shape of the ring 352 is adapted to the shape of the base 100. When the base 100 is rectangular, the ring 352 and the ring 352 are rectangular structures, and their shapes are not limited to ring structures.
[0053] Reference Figure 6 As a fifth embodiment of the connecting portion 300, the connecting portion 300 includes an elastic telescopic rod 370 and a clamping block 371. The elastic telescopic rod 370 is provided with at least one, and this embodiment takes three as an example. The three elastic telescopic rods 370 are spaced around the upper end of the dosing portion 200. One end of the elastic telescopic rod 370 is fixed to the dosing portion 200 (the two can also be detachably connected by bolts or other fastening methods). The other end of the elastic telescopic rod 370 is provided with a clamping block 371. The clamping block 371 has an arc surface 3711, and the arc surface 3711 can form a buckle or fit with the inner wall of the opening 101 of the base 100. When the elastic telescopic rod 370 is subjected to pressure along its length, it will elastically contract and reset after the external force is removed. In this way, when the medicine loading rack needs to be installed on the base 100, the block 371 is first squeezed toward the medication part 200, and then the elastic telescopic rod 370 is forced to contract, allowing the block 371 and the elastic telescopic rod 370 to enter the opening 101 of the base 100. Then, the squeezing force on the block 371 is removed, and the elastic telescopic rod 370 is reset and contacts the arc surface 3711 of the block 371 to form a clamping fit with the opening 101 of the base 100, thereby realizing the connection between the medicine loading rack and the base 100.
[0054] In this embodiment, the elastic telescopic rod 370 can be a conventional spring telescopic rod 340, which includes a large tube and a small tube movably inserted in the large tube. A spring is provided between the inner wall of the large tube at the end of the small tube. The small tube is compressed or reset by the spring, thereby driving the small tube to expand and contract in the large tube, thereby realizing the elastic expansion and contraction of the elastic telescopic rod 370. Of course, the elastic telescopic rod 370 can also be a rubber block, a compression spring or other elastic material. As long as the elastic telescopic rod 370 can be contracted to allow it to enter the opening 101 when the block 371 is plugged into the opening 101, and can touch the block 371 and form a buckle with the opening 101 after resetting, it will not be elaborated here.
[0055] Based on the above embodiments, in order to facilitate the connection between the connecting portion 300 and the upper end of the drug delivery portion 200, a fixing block 210 is further provided at the upper end of the drug delivery portion 200, and the drug delivery portion 200 is connected to the connecting portion 300 through the fixing block 210.
[0056] Based on the above embodiments, since the situations of stoma infections in different patients are different, and the infection areas and depths of the intestines at the stoma are different, in order to accurately adjust the depth of the drug delivery portion 200 inserted into the stoma intestine, the relative position of the drug delivery portion 200 and the base 100 can be adjustable to meet the drug delivery depth of the drug delivery portion 200 in the stoma. The specific adjustment method can be that the position of the connecting portion 300 and the base 100 is adjustable, or the position of the drug delivery portion 200 and the connecting portion 300 is adjustable, so as to adjust the drug delivery position of the drug delivery portion 200 inserted into the stoma. The following uses the above-listed embodiments to illustrate the adjustable drug delivery depth of the drug delivery portion 200 and the stoma;
[0057] Refer to Figure 3 In Figure (A) of , as an embodiment where the position between the drug delivery portion 200 and the connecting portion 300 is adjustable, an adjustment structure 400 can be provided between the drug delivery portion 200 and the connecting portion 300. The adjustment structure 400 can be a screw rod, and the screw rod is screwed on the fixing block 210. The fixing member is connected to the strut 310 or the telescopic rod 340 of the connecting portion 300. The lower end of the screw rod is connected to the drug delivery portion 200, and an adjustment knob is provided at the upper end. In this way, by rotating the adjustment knob on the fixing block 210, the drug delivery portion 200 can be driven to change its relative position to the base 100 in the vertical direction, so as to realize the adjustment of the drug delivery depth of the drug delivery portion 200 and the stoma.
[0058] Refer to Figure 3 (B) Figure, as an embodiment where the position between the connecting portion 300 and the base 100 is adjustable, the connecting portion 300 can be a telescopic rod 340. When the lower end of the telescopic rod 340 is hinged to the above-mentioned plug 311 (the specific hinge structure is not shown in the figure, and the specific hinge structure can be realized by existing universal rollers, hinge shafts or other structures to hinge the two), the upper end of the telescopic rod 340 is hinged to the upper end of the drug delivery portion 200 (or on the fixing block 210). Then, when the telescopic rod 340 is combined with the base 100 through the plug 311, by squeezing the fixing block 210 to move downward, the telescopic rod 340 is contracted, so that the drug delivery portion 200 moves downward, thereby changing the drug delivery depth of the drug delivery portion 200 and the stoma.
[0059] As another embodiment where the position between the drug delivery portion 200 and the base 100 is adjustable, specifically refer to Figure 2 , which is described in the second embodiment of the connecting portion 300 in this application, and will not be elaborated here.
[0060] In the above embodiments, the positions of the drug delivery part 200 and the connecting part 300 are adjustable, and the position between the connecting part 300 and the base 100 is also adjustable, all for the purpose of adjusting the drug delivery depth of the drug delivery part 200 at the stoma of the patient. Its two specific implementation manners can be used alone or in combination according to different embodiments. For example, referring to Figure 3 Figure (B) in
[0061] Based on the above embodiments, in order to improve the recycling rate of the entire drug carrier, the drug delivery part 200 is also provided with an openable drug storage cavity for storing drugs. The specific structure of the openable drug storage cavity is as follows: The inside of the drug delivery part 200 is hollow, and there are drug permeation holes on the surface. One end away from the fixed block 210 is provided with an opening communicating with its interior. Then the drug is stuffed into the drug storage cavity, and then the opening is closed, thus realizing the design of the openable drug storage cavity. Of course, the openable form of the drug storage part can also be a structure similar to a drawer. The drug is replaced by a drawer that can be plugged and unplugged on the drug delivery part. Of course, according to the different shapes of the drug delivery part 200, the openable drug storage cavity provided on the drug delivery part can also be other structures, which will not be specifically described here.
[0062] Based on the above embodiments, for the setting method of drugs on the drug carrier, according to the shape of the drug and the different drug use methods, the drugs can also be set on the drug delivery part 200 by means of smearing, adhesion or other setting methods.
[0063] Generally, a urinary catheter is set in the stoma of a patient undergoing a stoma operation. In order to avoid the urinary catheter being accidentally pulled out when a person changes the urine bag, the stoma device further includes a limiting member, which can be connected to the base 100 or arranged on the connecting part 300. By cooperating with the base by the limiting member, the position between the urinary catheter coiled on the base 100 and the base 100 is locked, thus avoiding the urinary catheter being accidentally pulled out when the patient changes the urine bag daily.
[0064] Referring to Figure 4, as an embodiment of the limiting member provided on the connecting portion 300, the recessed portion described in the third embodiment of the connecting portion 300 above is an embodiment of the limiting member; of course, the connecting member can also be provided on the base 100, and it can be a buckle, a magic tape, a tape or other structures that can be connected to the base 100 and can limit the catheter coiled in the annular groove 110. As long as the relative fixation between the catheter and the base 100 can be achieved to prevent the catheter from being accidentally pulled out of the patient's stoma, the catheter can also be of other structures, which can be provided on the connecting portion 300 or on the base 100, and will not be elaborated here.
[0065] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various changes and modifications can be made to the present invention for those skilled in the art.
