Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical nursing, in particular to a stoma bag. Background Art
[0002] After an abdominal drainage tube is inserted, due to various reasons, the drainage fluid may not flow out from the drainage tube but from the abdominal wall sinus tract, soaking the abdominal wall skin and causing irritant dermatitis. Moreover, as the leakage fluid increases, the wound dressing is permeated many times, increasing the workload of doctors. Currently, a one-piece urinary stoma bag is used for collection. The one-piece urinary stoma bag generally includes a chassis, an outer bag body and an inner bag body. The inner bag body is located inside the outer bag body. The chassis has a stoma hole. The collected liquid first enters the inner bag body through the stoma hole, and then flows into the outer bag body through two anti-reflux ports (similar to one-way valves) of the inner bag body that are connected to the inside of the outer bag body, and can be discharged from the discharge port of the outer bag body.
[0003] When the existing one-piece urinary stoma bag is used for collecting abdominal drainage fluid, the following problems exist: that is, since the abdominal drainage fluid is relatively viscous, the abdominal drainage fluid often does not flow smoothly when flowing out of the anti-reflux port. Therefore, when operating, the nurse needs to insert a finger through the stoma hole of the chassis into the bag body, pull out the inner bag body, cut a round hole with a diameter of about 2 cm on the inner bag body, damage the inner bag body, and place the drainage tube into the round hole so that the abdominal drainage fluid directly flows into the outer bag body. The disadvantages are: time-consuming, cumbersome operation, and waste of sterile scissors. Content of the Utility Model

At this time, the abdominal fluid directly enters the outer bag body 10 through the abdominal drainage tube, avoiding the problem of unsmooth flow when the abdominal fluid passes through the anti-reflux port 23 of the inner bag body 20, preventing the abdominal drainage fluid from being blocked and the drainage being unsmooth in the ostomy bag 100, effectively collecting the abdominal drainage fluid, preventing skin maceration dermatitis, and reducing the workload of doctors for dressing change; when it is used for collecting urine and the like, the first inlet 22 can be kept sealed by the sealing piece, and it can be used by passing through the stoma hole 31 of the chassis 30, the second inlet of the inner bag body 20, the second cavity 21 and each anti-reflux port 23 into the outer bag body 10 in sequence; and the first inlet 22 is provided at a position on the inner bag body 20 close to the stoma hole 31, so that the sealing piece at the first inlet 22 can be torn off more conveniently during use; it is applicable to a variety of usage scenarios, saving time, simple in operation, and without the need to use a sterile scissors, reducing consumables.
[0040] Among them, regarding the inner bag body 20 and the outer bag body 10:
[0041] In an alternative embodiment of the present invention, preferably, the sides of the inner bag body 20 and the outer bag body 10 away from the chassis 30 are both made of transparent materials. The sides of the inner bag body 20 and the outer bag body 10 opposite to the chassis 30 are made of transparent materials, which is convenient for observing the liquid conditions in the inner bag and the outer bag body 10, ensuring stable and safe use.
[0042] Specifically, there are two cases for the formation of the inner bag body 20. First, the inner bag body 20 can be an independent and complete bag body formed by itself; second, it can also be only a film layer, which is formed by covering the inner side wall of the outer bag body 10 with the chassis 30 (this is a common formation case); when the inner bag body 20 is in the first case, the second inlet of the inner bag body 20 is located on the side of the inner bag body 20 close to the chassis 30; when the inner bag body 20 is in the second case, the second inlet of the inner bag body 20 is located on the side of the outer bag body 10 with the chassis 30.
[0043] Specifically, taking the inner bag body 20 being composed of two pieces, namely the first film layer and the fourth film layer, and the outer bag body 10 being composed of two pieces, namely the second film layer and the third film layer, as an example to illustrate the first situation above: The first film layer and the fourth film layer of the inner bag body 20 are spliced relatively, and a second cavity 21 is formed inside; the second film layer and the third film layer of the outer bag body 10 are spliced relatively, and a first cavity 11 is formed inside, and the chassis 30 is fixed on the third film layer; the inner bag body 20 is located inside the first cavity 11, and the fourth film layer is located on the side of the first film layer close to the third film layer; at this time, the second inlet is arranged on the fourth film layer, and corresponding through holes are also arranged on the third film layer of the outer bag body 10, and the second inlet, the through holes and the stoma hole are communicated in sequence, and their sizes are the same.
[0044] Specifically, taking the inner bag body 20 as the first film layer and the outer bag body 10 being composed of two pieces, namely the second film layer and the third film layer, as an example to illustrate the second situation above: The second film layer and the third film layer of the outer bag body 10 are spliced relatively, and a first cavity 11 is formed inside, and the chassis 30 is fixed on the third film layer; the first film layer of the inner bag body 20 adheres to the side of the third film layer in the first cavity 11 away from the chassis 30, and the inner walls of the first film layer and part of the third film layer together form a second cavity 21, and the second inlet is arranged on the third film layer at this time, and the second inlet and the stoma hole are communicated in sequence.
[0045] Specifically, the anti-reflux port 23 on the inner bag body 20 is a one-way flow port that can only allow the liquid in the second cavity 21 of the inner bag body 20 to flow into the first cavity 11 of the outer bag body 10, and its formation method is the prior art and will not be elaborated here.
[0046] Specifically, the closing piece of the inner bag body 20 can cover the first inlet 22 in a bonded form, or can be located on the first inlet 22, and the circumferential edge of the closing piece is hermetically connected to the inner edge of the first inlet 22 in sequence. The closing piece is connected to the first inlet 22 in an easily tearable manner. When not in use, the closing piece seals and plugs the first inlet 22. When in use, the operator can tear off the closing piece to make the first inlet 22 in an open state.
[0047] Specifically, a raised piece can also be fixedly provided on the closing piece. When the operator needs to tear off the closing piece, the operator can hold the closing piece by gripping the raised piece.
[0048] Specifically, the closing piece can be arranged at a position on the inner bag body 20 opposite to the stoma hole 31, so as to facilitate finding the closing piece more quickly through the stoma hole 31 and tearing off the closing piece during use.
[0049] Specifically, the size of the first inlet 22 can be set according to the size of the abdominal drainage tube. For example, the size of the first inlet 22 is about 2 cm in diameter. Moreover, the size of the sealing piece can also be determined according to the size of the first inlet 22 and the matching manner with the first inlet 22. For example, when the first inlet 22 is about 2 cm in diameter, the sealing piece can be a tearable waterproof sticker with a diameter of about 2.5 cm. When collecting urine, there is no need to tear off the sealing piece. When collecting abdominal drainage fluid, the sealing piece is torn off, and there is no need to cut the inner bag body 20 with a sterile scissors.
[0050] In an alternative embodiment of the present invention, preferably, as Figure 1 shown, at one end of the outer bag body 10 away from the chassis 30, a first discharge port 12 is further provided. The first discharge port 12 communicates with the first cavity 11. A first plug 13 capable of blocking the first discharge port 12 is provided on the first discharge port 12. The arrangement of the first discharge port 12 and the first plug 13 can facilitate the timely discharge of the liquid collected in the outer bag body 10 and reduce the gravity burden of the patient wearing the ostomy bag 100.
[0051] In an alternative embodiment of the present invention, preferably, as Figure 1 shown, a flushing port 14 is further provided on the outer bag body 10. The flushing port 14 communicates with the first cavity 11, and a flushing plug 15 capable of blocking the flushing port 14 is provided on the flushing port 14. The arrangement of the flushing port 14 can facilitate the cleaning of the outer bag body 10 with a disinfectant or other cleaning liquid, so as to extend the service life while ensuring safe use, reduce the cost of medical equipment and the treatment cost of patients.
[0052] In an alternative embodiment of the present invention, preferably, as Figure 1 shown, a second discharge port 16 is further provided on the outer bag body 10. The second discharge port 16 communicates with the first cavity 11. A second plug 17 capable of blocking the second discharge port 16 is provided on the second discharge port 16. The first discharge port 12 is located at the lowest position of the outer bag body 10 in the patient's standing position. The second discharge port 16 is located at the lowest position of the outer bag body 10 in the patient's lying position. The arrangement of the second discharge port 16 and the second plug 17 facilitates the discharge of the liquid in the outer bag body 10 whether the patient is standing or lying, reduces the backflow of the liquid, and is beneficial to the recovery of the patient's condition.
[0053] Specifically, whether the second discharge port 16 is on the left or right side of the outer bag body 10 can be set according to the actual situation. For example, the urinary stoma and the hepatobiliary drainage tube are both on the right abdomen of the patient. Therefore, the corresponding second discharge port 16 is provided on the right side of the outer bag body 10.
[0054] In an alternative embodiment of the present invention, preferably, as Figure 1As shown, a scale line is provided on the side of the outer bag body 10 away from the chassis 30. The scale line provided on the outer bag body 10 can facilitate medical staff to more clearly understand the liquid discharge volume of the patient and timely understand the patient's condition.
[0055] Specifically, the scale line is a volume scale line 18, which is convenient for recording the drainage volume.
[0056] Among them, regarding the chassis 30:
[0057] In an alternative embodiment of the present invention, preferably, as Figure 1 shown, a backing paper 32 is adhered to the bonding part of the chassis 30. The backing paper 32 corresponds to the shape of the chassis 30, and the backing paper 32 includes multiple segments. The multiple segments together form a complete backing paper 32, and an easy tear line 323 is provided between adjacent segments. The backing paper 32 is composed of multiple segments, and an easy tear line 323 (similar to the easy tear line 323 provided on toilet paper rolls) is provided between adjacent segments. When removing the backing paper 32 to paste the chassis 30 on the part to be pasted of the patient, the segments can be gradually removed, and the corresponding pasting parts on the chassis 30 can be gradually bonded, reducing the risk of uneven pasting, wrinkling, and even the liquid from the stoma hole 31 flowing out from the pasting part of the chassis 30 caused by directly pasting the whole chassis 30 after removing the whole backing paper 32.
[0058] Specifically, the easy tear line 323 is a radially arranged easy tear break point, and its quantity can be set according to actual needs.
[0059] In an alternative embodiment of the present invention, preferably, as Figure 1 shown, a holding protrusion 322 protruding from the edge of the chassis 30 is provided on each segment. The holding protrusion 322 provided on each segment makes it easier to hold and pinch the corresponding segment during use, so as to perform the removal operation on the corresponding segment.
[0060] In an alternative embodiment of the present invention, preferably, as Figure 1 shown, a plurality of stoma reference circumference lines 321 are provided on the backing paper 32. The setting of the stoma reference circumference lines 321 facilitates guiding the appropriate cutting of the stoma hole 31 size on the chassis 30 according to the stoma size during use.
[0061] In an alternative embodiment of the present invention, preferably, the chassis 30 is made of a flexible material. The chassis 30 made of a flexible material can be fully attached to the part to be pasted of the patient, ensuring the pasting sealing effect and improving the comfort of the pasting part of the patient.
[0062] Specifically, the material of the chassis 30 and the material of the backing paper 32 can both be any existing material, which will not be elaborated here; thus making the chassis 30 softer, increasing its affinity with the skin, improving the comfort of the patient during use, and reducing the pain of the patient.
[0063] Among them, the descriptions of other relevant settings are as follows:
[0064] Specifically, a micro rapid discharge device can be added to the first row of outlets and the second row of outlets of the outer bag body 10. Since the abdominal drainage fluid is relatively viscous, the added micro rapid discharge device is used to increase the discharge speed of the abdominal drainage fluid in the outer bag body 10 and reduce the residue of the abdominal drainage fluid in the outer bag body 10; the micro rapid discharge device can be any existing small device or equipment that cooperates with the first row of outlets and the second row of outlets to discharge the abdominal drainage fluid in the outer bag body 10.
[0065] Specifically, to ensure that the micro rapid discharge device stably discharges the abdominal drainage fluid in the outer bag body 10 without causing suction effect on the patient's stoma, the flushing port 14 provided on the outer bag body 10 can be opened synchronously, or an additional air inlet can be added to the outer bag body 10; when using the micro rapid discharge device to aspirate and discharge the abdominal drainage fluid in the outer bag body 10, a sterile gas device can be connected to the flushing port 14 or the air inlet used in cooperation, so as to ensure that the gas in the outer bag body 10 does not affect the patient's stoma.
[0066] Specifically, the size of the flushing port 14 on the outer bag body 10 can be set according to actual needs. For example, when a syringe is used for flushing operation, the size of the flushing port 14 is the same as the size of the end outlet of the syringe barrel, and the flushing port 14 can have a certain depth so that the end outlet of the syringe barrel can be inserted and fixed at the flushing port 14.
[0067] Specifically, the provided air inlet can also be used in combination with the flushing port 14, that is, after cleaning, the ostomy bag 100 can be made flatter, reducing the wrinkles generated in the bag body after cleaning and discharging.
[0068] In the present utility model, specific examples are used to elaborate the principle and implementation manner of the present utility model. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
