Description

Technical Field

[0001] The utility model belongs to the technical field of medical nursing tools, and in particular relates to a feces collecting device which can be used for drainage and enema. Background Art

[0002] For patients with common diarrhea and fecal incontinence in gastroenterology, especially severe patients with ulcerative colitis and dysbacteriosis, diarrhea and fecal incontinence can easily cause moisture in the perianal skin, which in turn causes physical and mental discomfort in patients. In addition, the continuous stimulation of the perianal skin by fecal water can easily cause incontinence dermatitis. At the same time, in the clinical nursing process, improper, repeated and frequent cleaning and wiping of the perianal skin can easily lead to perianal skin damage, and the damaged skin can easily be contaminated by fecal water, further aggravating skin damage and the occurrence of infection.

[0003] For patients with diarrhea and fecal incontinence, in addition to systemic medication, local enema treatment is also a major treatment measure. However, repeated intubation during enema operation can easily cause serious intestinal perforation, delaying the patient's disease recovery process and increasing the patient's economic burden. In this regard, a Chinese patent with authorization announcement number CN219462060U discloses a drainage device for diarrhea patients. By setting an inner tube and an outer surface, enema is performed through the inner tube during enema operation. Although it solves the problem of drainage and enema single channel and preventing the drainage device from falling off, it cannot manage the enema fluid in stages.

[0004] The characteristic of the human rectum structure is that the rectum is not straight, but forms two obvious bends on the sagittal plane, namely the rectosacral flexure and the rectoperineal flexure. When encountering resistance during enema insertion, the action should be gentle, and care should be taken to avoid damaging the intestinal wall. In addition, the defecation receptors are the mucosa at the lower end of the rectum and the skin of the anal canal, which play a vital role in the defecation process, so they are called defecation switches.

[0005] Based on this, the utility model intends to design a device that can be used for both drainage and enema, which can not only realize the enema operation, but also more easily adapt to the physiological structure of the human body and is convenient to be fixed in the rectum of the human body.

[0098] Further preferably, in this embodiment, the straight side wall of the first inner tube 23 and the straight side wall of the second inner tube 24 are close to and abut against each other, so that the left end of the first inner tube 23 and the left end of the second inner tube 24 form a cylindrical structure.

[0099] A first drainage joint 26 is provided at the right end tail of the first inner tube 23, and a second drainage joint 27 is provided at the right end tail of the second inner tube 24. A first one-way valve (not marked in the figure) is installed on the first drainage joint 26, and a second one-way valve (not marked in the figure) is installed on the second drainage joint 27. Through the first one-way valve (not marked in the figure) and the second one-way valve (not marked in the figure), the flushing liquid can flow from the first drainage joint 26 at the right end of the first inner tube 23 into the first inner tube 23, and the flushing liquid can flow from the second drainage joint 27 at the right end of the second inner tube 24 into the second inner tube 24 without backflow.

[0100] Furthermore, the distance between the leftmost end of the first inner tube 23 and the connection between the outer tube 21 and the end cover is smaller than the distance between the leftmost end of the second inner tube 24 and the connection between the end cover.

[0101] like Figure 1 , 2 As shown, the front side wall, the rear side wall and the lower side wall of the outer tube 21 are provided with a plurality of first Murphy's eye rows 28 near the left end of the head, and the front side wall, the rear side wall and the lower side wall of the outer tube 21 are provided with a plurality of second Murphy's eye rows 29 between the first air bag 31 and the second air bag 32;

[0102] Each first row of Murphy's eyes 28 and each second row of Murphy's eyes 29 are arrays formed by a plurality of Murphy's eyes of blunt structure, and the first row of Murphy's eyes 28 and the second row of Murphy's eyes 29 avoid the first airbag 31, the second airbag 31, the first airbag catheter 34, the second airbag catheter 35 and the sensor wire 33;

[0103] The first row of Murphy's eyes 28 and the second row of Murphy's eyes 29 correspond to the parts of the colon and the rectum, respectively.

[0104] A first arc-shaped limiting ring 211 and a second arc-shaped limiting ring 212 are provided on the inner wall of the middle tube penetration cavity 215 near the right opening. The first limiting ring 211 and the second limiting ring 212 are symmetrically arranged on the upper inner wall and the lower inner wall of the middle tube penetration cavity 215; preferably, the sum of the vertical widths of the first limiting ring 211 and the second limiting ring 212 is equal to the vertical width of the gap between the middle tube 22 and the middle tube penetration cavity 215;

The first abutment ring 221 and the second abutment ring 222 are symmetrically arranged at the top and bottom of the outer wall of the middle tube 22.

[0106] The sum of the vertical widths of the first abutment ring 221 and the second abutment ring 222 is equal to the vertical width of the gap between the middle tube 22 and the middle tube penetration cavity 215; by abutting the first abutment ring 221 on the right side of the first limiting ring 211 and the second abutment ring 222 on the right side of the second limiting ring 212, the relative position between the middle tube 22 and the outer tube 21 can be limited when the middle tube 22 extends from the opening at the right end of the outer tube 21 into the middle tube penetration cavity 215;

[0107] Specifically, by adjusting the bonding position between the first inner tube 23 and the side wall of the middle tube 22, and the bonding position between the second inner tube 24 and the side wall of the middle tube 22, the distance between the leftmost end of the first inner tube 23 and the connection between the outer tube 21 and the end cover is smaller than the distance between the leftmost end of the middle tube 22 and the connection between the outer tube 21 and the end cover, and the distance between the leftmost end of the second inner tube 24 and the connection between the end cover is larger than the distance between the leftmost end of the middle tube 22 and the connection between the outer tube 21 and the end cover, that is, the left end of the first inner tube 23 partially extends out from the left end of the middle tube;

[0108] Further preferably, in this embodiment, by adjusting the bonding position of the first inner tube 23 and the side wall of the middle tube 22, and the bonding position of the second inner tube 24 and the side wall of the middle tube 22, the leftmost end of the first inner tube 23 corresponds to the position of the first Murphy's eye row 28 of the outer tube 21, and the leftmost end of the second inner tube 24 corresponds to the position of the second Murphy's eye row 29; the drainage of the flushing liquid and the intestinal fluid is facilitated;

[0109] In addition, drainage notches 223 are provided on the front and rear side walls of the middle tube 22 at positions corresponding to the leftmost end of the second inner tube 24 to facilitate drainage of flushing liquid and intestinal fluid after flushing from the second inner tube 24 .

[0110] The fixing mechanism includes an adhesive sheet and two fixing devices; the adhesive sheet is detachably connected to the outer tube 21 through the two fixing devices;

[0111] The adhesive sheet includes a circular bottom plate 41 and a plurality of lace strips 42 arranged on the outer periphery of the bottom plate 41. A through hole is provided in the center of the bottom plate 41 for the outer tube 21 to pass through. Both the bottom plate 41 and the lace strips 42 are provided with adhesive that can fit the human skin.

[0112] Each fixator includes a first positioning strip 43, a second positioning strip 44 and an adhesive block 45, and the two fixators are symmetrically arranged at the upper and lower ends of the outer surface of the outer tube 21; specifically, the two fixators are close to the opening at the right end of the outer tube 21; further preferably, the distance between the two fixators and the second airbag 32 corresponds to the distance between the upper side of the human anal canal and the anus;

[0113] The second positioning strip 44 is provided with an insertion hole, and the bottom plate 41 is provided with a long strip through hole 46 for the first positioning strip 43 to pass through. The end of the first positioning strip 43 and the adhesive block 45 are provided with Velcro that can be tightly attached to each other. The end of the first positioning strip 43 can pass through the insertion hole and the long strip through hole 46 on the bottom plate 41 in turn, and be bonded to the adhesive block 45.

[0114] Since the distance between the anus and the perineum is about 2-4 cm, which is relatively short, there are 7 lace strips 42 in this embodiment. The 7 lace strips 42 are fixed to the front end, rear end and bottom end of the outer periphery of the base plate 41, and no lace strip 42 is set at the position corresponding to the perineum of the human body.

[0115] When in use, the outer tube 21 can be inserted through the through hole in the center of the bottom plate 41, and the relative positions of the outer tube 21 and the adhesive sheet can be adjusted until the two fixers are moved to correspond to the positions of the bottom plate 41. At this time, the first positioning strip 43 is located on the left side of the bottom plate 41, and the adhesive block 45 is located on the right side of the bottom plate 41.

[0116] Then the base plate 41 and the lace strip 42 are fixed to the patient's anus, and the position on the base plate 41 where the lace strip 42 is not set is opposite to the middle part of the patient's anus and perineum. Then, the end of the first positioning strip 43 passes through the insertion hole on the second positioning strip 44 and the long strip through hole 46 on the base plate 41 in sequence, and is bonded to the adhesive block 45, thereby realizing the connection between the outer tube 21 and the adhesive sheet, which plays a role in proper fixation.

[0117] The utility model can achieve the dual purposes of drainage and enema by arranging the nested structure of the outer tube 21, the middle tube 22, the first inner tube 23 and the second inner tube 24.

[0118] The use principle of the utility model is:

[0119] Before use, first, the left end of the sensor wire 33 is passed from the opening at the right end of the outer tube 21 to the left into the catheter insertion cavity 214, and electrically connected to the CMOS micro image sensor 2 in the end cap, and the right end of the sensor wire 33 is electrically connected to an external data acquisition device, and then the end cap is installed on the left end of the outer tube 21, and the first one-way valve and the second one-way valve are closed;

[0120] Then, the middle tube 22 is inserted from the right end of the middle tube insertion cavity 215, and abutted against the right side of the first limiting ring 211 through the first abutting ring 221, and the second abutting ring 222 abuts against the right side of the second limiting ring 212, so that when the middle tube 22 extends from the opening at the right end of the outer tube 21 into the middle tube insertion cavity 215, the relative position between the middle tube 22 and the outer tube 21 is limited;

[0121] Then, the outer tube 21 is inserted through the through hole in the center of the bottom plate 41, and the relative positions of the outer tube 21 and the adhesive sheet are adjusted until the two fixers are moved to correspond to the positions of the bottom plate 41. Then, the bottom plate 41 and the lace strip 42 are fixed to the patient's anus. The position on the bottom plate 41 where the lace strip 42 is not provided faces the middle part of the patient's anus and perineum. Then, the end of the first positioning strip 43 passes through the insertion hole and the long strip through hole 46 on the bottom plate 41 in sequence, and is bonded to the adhesive block 45, thereby realizing the connection between the outer tube 21 and the adhesive sheet.

[0122] When in use, the first inflation one-way valve and the second inflation one-way valve are first opened to deflate the first airbag catheter 34 and the second airbag catheter 35, and then the tube body is inserted into the human rectum from the human anus. During the insertion process, the rectal position is observed by the CMOS micro image sensor 2 to determine the insertion position. When the first airbag 31 is moved to the position corresponding to the sigmoid part of the rectum and the second airbag 32 is moved to the position above the anal canal, the first inflation one-way valve and the second inflation one-way valve are opened to inflate the first airbag 31 and the second airbag 32 to fix the relative positions of the first airbag 31 and the second airbag 32 and the rectum. At the same time, the air pressure is detected by the first pressure detection mechanism and the second pressure detection mechanism. When the predetermined air pressure is reached, the first inflation one-way valve and the second inflation one-way valve are immediately closed.

[0123] Then, the adhesive on the lace strip 42 is used to fix the fixing mechanism around the human anus and keep the relative position between the tube body and the human rectum fixed;

[0124] At this time, the first one-way valve is opened, and the enema solution is filled into the first inner tube 23 and passed through the first Murphy's eye row 28 to perform enema on the upper part of the rectum sigmoid; or the second one-way valve is opened, and the enema solution is filled into the second inner tube 24 and passed through the second Murphy's eye row 29 to perform enema on the rectum above the anal canal;

[0125] Anti-backflow valves 25 are provided at the left end of the first inner tube 23 near the opening and at the left end of the second inner tube 24 near the opening to prevent fecal water from flowing back into the first inner tube 23 and the second inner tube 24;

[0126] After enema, the enema liquid refluxed from the rectum flows from the middle tube 22 into the anti-backflow drainage bag 6 for collection, thereby achieving the dual purpose of enema and drainage.

[0127] In specific clinical operations, for example, when the lesion of a patient is mainly in the colon and a small-dose retention enema is performed with a drug, the first airbag 71 can be inflated and blocked first, and the first one-way valve can be closed to prevent drainage. Then, a flushing liquid with a suitable temperature is flushed into the colon cavity to allow the drug liquid to fully contact the colon cavity. After a certain time requirement, the second airbag 72 is inflated, and then the first one-way valve is opened. The first airbag 71 is evacuated, and the drug liquid and intestinal fluid are immediately drained out of the body, thereby preventing the liquid from leaking out through the anus.

[0128] For example, if the lesion is only in the rectum, when a small-dose retention enema is performed, the first one-way valve and the second one-way valve on the first airbag 71 and the second airbag 72 can be closed to prevent the drug solution from moving to the colon and the anus, and then the drug solution at a suitable temperature is flushed into the rectum. After a certain period of time, the first one-way valve of the first airbag 71 is opened, and the drug solution and intestinal fluid are immediately drained out of the body, and leakage of the liquid through the anus is also avoided. By controlling the first one-way valve and the second one-way valve, the enema liquid is managed in stages.

[0129] The advantages of the device of the utility model are:

[0130] 1. The utility model adopts a double-airbag design, which can effectively improve the fixing effect of the entire device in the rectum; the utility model can also achieve phased management of enema liquid by inflating and deflating the first airbag 31 and the second airbag 32.

[0131] 2. The utility model adopts an end cap installed on the left end of the head, and a photometric head 1 and a CMOS micro-image sensor 2 structure are arranged inside the end cap, which can realize visual operation during the intubation process and effectively avoid the occurrence of intestinal perforation.

[0132] 3. The fixing mechanism of the present invention can effectively fix the tube body externally by adjusting the setting position of the lace strip 42 on the outer periphery of the bottom plate 41, thereby avoiding the problem of irregular skin structure at the pasting site and being aesthetically pleasing.

[0133] 4. The utility model adopts a dual design of internal fixation of the first inner tube 23, the second inner tube 24 and the middle tube 22 and internal fixation of the middle tube 22 and the outer tube 21 + external fixation of the fixing mechanism, which can effectively reduce the risk of catheter slippage.

[0134] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
