Description

Bowel contents transfer device for ostomy patients

[0001] The present invention relates to a device for delivering intestinal contents for an ostomy patient.

[0002] When the digestive or urinary organs are damaged due to an accident or illness, preventing the smooth passage of stool or urine, an artificial colostomy can be used to remove waste from the body. The artificial anus, exposed to the outside for this purpose, is commonly referred to as a stoma.

[0003] Total parenteral nutrition (TPN) can be administered to patients with ostomy tubes who are unable to consume oral nutrition. TPN is a mixture of over 40 substances, including glucose, amino acids, lipids, electrolytes, trace elements, and vitamins. It is typically administered intravenously using a large-bore needle or catheter.

[0004] However, TPN is approximately 5-6 times more concentrated than blood, which can damage peripheral veins and lead to complications such as phlebitis. Furthermore, intravenous TPN administration is difficult for patients with weak blood vessels, such as pediatric ostomy patients.

[0005] Therefore, there is a need for a technology to minimize intravenous TPN administration.

[0006] The present invention provides an intestinal contents delivery device for an ostomy patient, which is inserted into the ostomy and delivers intestinal contents from an upper ostomy to a lower ostomy for patients who have difficulty in receiving intravenous TPN.

[0007] In addition, the present invention provides an intestinal contents delivery device for an ostomy patient, which has a shape that does not cause damage to the patient's ostomy when supplying TPN through the ostomy.

[0008] In addition, the present invention provides an intestinal contents delivery device for an ostomy patient, which is inserted into the ostomy to deliver intestinal contents from the upper ostomy to the lower ostomy and is easily attached to the patient's skin.

[0009] Meanwhile, the technical tasks to be achieved in the present invention are not limited to the technical tasks mentioned above, and other technical tasks not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which the present invention belongs from the description below.

[0010] An intestinal contents delivery device for an ostomy patient according to an embodiment of the present invention includes a nutrient delivery tube having a nutrient delivery passage that is inserted into the ostomy of the patient to deliver intestinal contents between an upper ostomy and a lower ostomy, and a nutrient supply tube that is connected to one side of the nutrient delivery tube so as to be in communication with the nutrient delivery passage.

[0011] The nutritional delivery tube may include an upper stoma insertion tube that is provided to be insertable into an upper stoma, has a first nutritional delivery passage, and has at least one first opening formed at one end thereof to allow intestinal contents existing in the upper stoma to flow in, and a lower stoma insertion tube that is provided to be insertable into a lower stoma, has a second nutritional delivery passage that communicates with the first nutritional delivery passage, and has at least one second opening formed at one end thereof to allow intestinal contents delivered from the upper stoma through the first opening and the first nutritional delivery passage to be delivered to the lower stoma.

[0012] The above nutritional supply tube can be formed to communicate with the first nutritional delivery passage and the second nutritional delivery passage between the upper ostomy insertion tube and the lower ostomy insertion tube.

[0013] In addition, the intestinal contents delivery device for an ostomy patient according to an embodiment of the present invention may further include a check valve provided at a connection between the nutrient supply tube and the nutrient delivery tube to prevent backflow of a medication injected through the nutrient supply tube.

[0014] The above check valve may be configured to open to allow the drug solution injected through the nutrient supply tube to flow into one of the first nutrient delivery passage and the second nutrient delivery passage, and to block the other of the first nutrient delivery passage and the second nutrient delivery passage.

[0015] The above check valve can be opened when the drug is injected, so that the drug is in contact with the inner surface of the lower stoma insertion tube, preventing the drug from flowing into the lower stoma insertion tube, and allowing the drug to be supplied to the stoma through the upper stoma insertion tube.

[0016] Both ends of the above nutritional delivery tube may be provided in a hemispherical closed shape to prevent damage to the user's stoma.

[0017] The length of the above nutrient delivery tube may be 6 cm or more and 10 cm or less.

[0018] The feeding tube inserted into the stoma may further include at least one adhesive portion having an adhesive surface that is attached to the user's skin to prevent the feeding tube from being detached from the user.

[0019] The above adhesive portion can be formed to be connected to a connection portion between a nutrient supply tube and a nutrient delivery tube.

[0020] The material of the above nutrient delivery tube and nutrient supply tube may be synthetic resin.

[0021] According to an embodiment of the present invention, an intestinal contents delivery device for an ostomy patient can be provided that is inserted into the ostomy to deliver intestinal contents from an upper ostomy to a lower ostomy for patients who have difficulty in receiving TPN through a vein.

[0022] In addition, according to an embodiment of the present invention, it is possible to provide an intestinal contents delivery device for an ostomy patient having a shape that does not cause damage to the patient's ostomy when supplying TPN through the ostomy.

[0023] In addition, according to an embodiment of the present invention, it is possible to provide an intestinal contents delivery device for an ostomy patient that can be inserted into an ostomy to deliver intestinal contents from an upper ostomy to a lower ostomy to help with nutrient absorption in the lower intestine, and at the same time, can be easily attached to the patient's skin.

However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals designate like elements throughout the specification. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0033] FIG. 1 is an exemplary diagram showing an intestinal contents delivery device for an ostomy patient according to an embodiment of the present invention, FIG. 2 is a front view of an intestinal contents delivery device for an ostomy patient according to an embodiment of the present invention, FIG. 3 is an exemplary diagram for explaining the operation of a check valve according to an embodiment of the present invention, FIG. 4 is an exemplary diagram for explaining the operation of a check valve according to an embodiment of the present invention, and FIG. 5 is an exemplary diagram for explaining the operation of a check valve according to an embodiment of the present invention.

[0034] Referring to FIGS. 1 to 5, an intestinal contents delivery device for an ostomy patient according to an embodiment of the present invention may include a nutrition delivery tube (100), a nutrition supply tube (200), and a check valve (300).

[0035] A nutritional delivery tube (100) may be inserted into a user's stoma and may have a nutritional delivery passage (101, 102) for delivering intestinal contents between an upper stoma (1) and a lower stoma (2).

[0036] Here, a stoma refers to an artificial opening surgically created to secure a portion of the intestine to the abdominal wall to facilitate the excretion of stool when normal stool excretion is disrupted. Nutrients can refer to intestinal contents digested in the patient's upper intestine and excreted through the upper stoma (1).

[0037] In addition, the upper stoma (1) refers to a resected portion of the intestine that digests nutrients earlier than the lower stoma (2) in the digestive process, and the lower stoma (2) refers to a resected portion of the intestine that digests nutrients later than the upper stoma (1) in the digestive process.

[0038] The nutritional delivery tube (100) may include an upper stoma insertion tube (110) and a lower stoma insertion tube (120).

[0039] An upper stoma insertion tube (110) may be provided so as to be insertable into an upper stoma (1). The upper stoma insertion tube (110) may be provided with a first nutrient delivery passage (101).

[0040] Additionally, the upper stoma insertion tube (110) may have at least one first opening (111) formed at one end thereof to allow nutrients present in the upper stoma (1) to flow in.

[0041] Here, the term "end" refers to the end of the upper ostomy insertion tube (110) that is not in communication with the lower ostomy insertion tube (120). That is, the term "end" of the upper ostomy insertion tube (110) and the term "end" of the lower ostomy insertion tube (120) refer to both ends of the nutrition delivery tube (100).

[0042] Accordingly, the first opening (111) can be arranged at one end of the upper stoma insertion tube (110) so that the medicine introduced into the first nutrient delivery passage (101) is provided to the upper stoma (1) without flowing out of the user's body.

[0043] The first opening (111) can be formed in the side wall of the upper stoma insertion tube (110) so that the first nutrient delivery passage (101) and the upper stoma (1) are connected.

[0044] By this, nutrients introduced through the first port (111) can be delivered to the second nutrient delivery channel (102) through the first nutrient delivery channel (101). In addition, the medicinal solution introduced into the first nutrient delivery channel (101) of the upper stoma insertion tube (110) can be supplied to the upper stoma (1) through the first port (111).

[0045] In addition, since the first hole (111) is formed on the side wall of the upper stoma insertion tube (110), the flow rate of the medicine introduced into the first nutrient delivery passage (101) can be slowed down in the process of moving to the upper stoma (1) through the first hole (111).

[0046] This can reduce the stimulation that the medicinal liquid exerts on the user's intestines due to the rapid flow rate when the medicinal liquid is introduced into the upper stoma (1).

[0047] The length of the first opening (111) may be 0.6 cm to 1 cm. If it is less than 0.6 cm, the amount of medicine flowing out through the first opening (111) is reduced, so the time for supplying the medicine is prolonged. If it is more than 1 cm, the stress of the upper stoma insertion tube (110) is reduced, so that the upper stoma insertion tube (110) may bend because it cannot withstand the pressure applied by the inner wall of the upper stoma (1).

[0048] A lower ostomy insertion tube (120) may be provided so as to be insertable into a lower ostomy (2). The lower ostomy insertion tube (12) may be provided with a second nutrient delivery passage (102) communicating with the first nutrient delivery passage (101).

[0049] Additionally, the lower stoma insertion tube (120) may have at least one second port (121) formed at one end thereof to deliver nutrients delivered from the upper stoma (1) through the first port (111) and the first nutrient delivery passage (101) to the lower stoma (2).

[0050] A second opening (121) can be formed in the side wall of the lower stoma insertion tube (120) so that the second nutrient delivery passage (102) and the lower stoma (2) are connected.

[0051] In addition, since the second hole (121) is formed on the side wall of the lower stoma insertion tube (120), the flow rate of the medicine and / or nutrients introduced into the second nutrient delivery passage (102) can be slowed down in the process of moving to the lower stoma (2) through the second hole (121).

[0052] This can reduce the stimulation to the user's intestines due to the rapid flow of the medicine and / or nutrients when the medicine and / or nutrients are introduced into the lower stoma (2).

[0053] The length of the second hole (121) may be 0.6 cm to 1 cm. If it is less than 0.6 cm, the amount of medicine flowing out through the second hole (121) is reduced, so the time for medicine supply is prolonged. If it is more than 1 cm, the stress of the lower stoma insertion tube (120) is reduced, so that the lower stoma insertion tube (120) may bend because it cannot withstand the pressure applied by the inner wall of the lower stoma (2).

[0054] Both ends of the nutritional delivery tube (100) may be provided in a hemispherical closed shape to prevent damage to the user's stoma.

[0055] Additionally, the length value (L) of the nutrient delivery tube (100) may be 6 cm or more and 10 cm or less. However, this is not necessarily limited to the length value (L) of the preferred nutrient delivery tube (100) according to the embodiment of the present invention.

[0056] If the length value (L) of the nutrition delivery tube (100) is less than 6 cm, the length at which the nutrition delivery tube (100) is inserted into the stoma (1, 2) becomes short, and the medication injected into the nutrition supply tube (200) may leak out of the user's body.

[0057] In addition, if the length value (L) of the nutritional delivery tube (100) is 10 cm or more, the length that must be inserted into the stoma (1, 2) becomes longer, which may cause irritation to the intestines of a pediatric stoma patient with weak blood vessels.

[0058] The nutrient supply tube (200) can be connected to one side of the nutrient delivery tube (100) so as to be in communication with the nutrient delivery passage (101, 102).

[0059] Specifically, the nutritional supply tube (200) can be formed to communicate with the first nutritional delivery passage (101) and the second nutritional delivery passage (102) between the upper ostomy insertion tube (110) and the lower ostomy insertion tube (120).

[0060] By this, the drug solution injected into the nutritional supply tube (200) can be introduced into the upper stoma (1) and / or the lower stoma (2) through the first nutritional delivery passage (101) and / or the second nutritional delivery passage (102).

[0061] The nutrition delivery tube (100) and the nutrition supply tube (200) may be made of an elastic material. Accordingly, the angle at which the nutrition delivery tube (100) and the nutrition supply tube (200) are connected may be modified depending on the location and / or shape of the user's stoma (1, 2).

[0062] For example, the material of the nutrient delivery tube (100) and the nutrient supply tube (200) may be synthetic resin. Specifically, the material of the nutrient delivery tube (100) and the nutrient supply tube (200) may be latex or PVC (Polyvinyl Chloride), but is not necessarily limited thereto.

[0063] A check valve (300) may be provided at the connection between the nutrient supply tube (200) and the nutrient delivery tube (100) to prevent backflow of the drug solution injected through the nutrient supply tube (200). For example, the check valve (300) may be positioned so as to be in contact with the inner surface of the nutrient supply tube (200).

[0064] By this, the check valve (300) can block the user's stoma (1, 2) from the outside of the user's body when no medication is injected into the nutritional supply tube (200).

[0065] The check valve (300) can be configured to open so that the drug solution injected through the nutrient supply tube (200) can flow into one of the first nutrient delivery passage (101) and the second nutrient delivery passage (102), and to block the other one of the first nutrient delivery passage (101) and the second nutrient delivery passage (102).

[0066] For example, the check valve (300) can be opened to contact the inner surface of the lower stoma insertion tube (120) when the drug is injected, thereby preventing the drug from flowing into the lower stoma insertion tube (120), while allowing the drug to be supplied to the upper stoma (1) through the upper stoma insertion tube (110).

[0067] At this time, the check valve (300) can be opened and closed by being coupled to the first point (A) to allow the injected drug to flow into the first nutrient delivery passage (101).

[0068] Conversely, the check valve (300) may be opened to contact the inner surface of the upper stoma insertion tube (110) upon injection of the drug solution, thereby preventing the drug solution from flowing into the upper stoma insertion tube (110) and allowing the drug solution to be supplied to the lower stoma (2) through the lower stoma insertion tube (120).

[0069] At this time, the check valve (300) can be opened and closed by being coupled to the second point (B) to allow the injected drug to flow into the second nutrient delivery passage (102).

[0070] The check valve (300) can be opened and closed by being coupled to either the first point (A) or the second point (B). The way in which the check valve (300) is coupled to the first point (A) and / or the second point (B) may be a hinge coupling, but is not necessarily limited thereto.

[0071] The operation of the check valve (300) will be described below.

[0072] When the medicine is injected through the nutrient supply tube (200), the check valve (300) positioned to contact the inner surface of the nutrient supply tube (200) can be opened by the weight of the injected medicine and / or the injection pressure.

[0073] At this time, when the check valve (300) is connected to the first point (A) and opens and closes, the check valve (300) can be opened to come into contact with the inner surface of the lower ostomy insertion tube (120).

[0074] By this, the drug can be shielded so that it flows into the first nutrient delivery passage (101) and does not flow into the second nutrient delivery passage (102).

[0075] The medicinal solution introduced into the first nutrient delivery channel (101) can be introduced into the upper stoma (1) through the first opening (111).

[0076] As another example, when the check valve (300) is connected to the second point (B) and opens and closes, the check valve (300) can be opened to come into contact with the inner surface of the upper ostomy insertion tube (110).

[0077] By this, the drug can flow into the second nutrient delivery passage (102) and be shielded from flowing into the first nutrient delivery passage (101). The drug introduced into the second nutrient delivery passage (102) can flow into the lower stoma (2) through the second opening (121).

[0078] When no force is applied to the check valve (300), the check valve (300) can be positioned to contact the inner surface of the feeding tube to block the stoma (1, 2) from outside the user's body.

[0079] This can prevent air and / or foreign substances outside the user's body from entering the stoma.

[0080] Additionally, when there is no force applied to the check valve (300), the check valve (300) may be placed in contact with the inner surface of the nutrient supply tube (200) so that the first nutrient delivery passage (101) and the second nutrient delivery passage (102) are connected.

[0081] Through this, the check valve (300) can move the medicinal solution introduced into the upper stoma (1) to the lower stoma (2) and be absorbed after the absorption is completed.

[0082] This can improve the absorption rate of the injected medicine compared to the case where the nutrients of the injected medicine are absorbed using only the upper stoma (1).

[0083] Specifically, when no force is applied to the check valve (300), nutrients introduced through the first hole (111) can be delivered to the second nutrient delivery passage (102) through the first nutrient delivery passage (101).

[0084] At this time, nutrients are not introduced into the nutrient supply tube (200) by the check valve (300), but are introduced into the lower stoma (2) through the second hole (121) and can be absorbed.

[0085] This can reduce the hassle of refeeding, which was previously performed to increase the absorption rate of medication in the user's body. Refeeding refers to the process of recovering medication injected into the upper stoma (1) and then re-injecting it into the lower stoma (2).

[0086] FIG. 6 is a perspective view of an intestinal contents delivery device for an ostomy patient according to another embodiment of the present invention, and FIG. 7 is an exemplary view for explaining a state of use of an intestinal contents delivery device for an ostomy patient according to another embodiment of the present invention.

[0087] Referring to FIGS. 1 to 7 together, an intestinal contents delivery device for an ostomy patient according to another embodiment of the present invention may further include an adhesive portion (400).

[0088] The adhesive portion (400) may have an adhesive surface that is attached to the user's skin to prevent the nutritional delivery tube (100) inserted into the stoma (1, 2) from being detached from the user.

[0089] The adhesive portion (400) may be formed to be connected to a connection between a nutrient supply tube (200) and a nutrient delivery tube (100). This allows the user to easily attach the intestinal contents delivery device to the patient's skin while simultaneously supplying nutrients through the stoma (1, 2).

[0090] There may be at least one adhesive member (400). Preferably, the number of adhesive members (400) may be two, but this is not necessarily limited. When there are two adhesive members (400), they extend in different directions, allowing the intestinal contents delivery device to be more stably fixed so that it does not detach from the stoma (1, 2).

[0091] While specific embodiments of the present invention have been described so far, it is to be understood that various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims set forth below but also by their equivalents. Although the present invention has been described with reference to limited embodiments and drawings, it is not limited to the above-described embodiments, and various modifications and variations may be made by those skilled in the art based on this description. Therefore, the spirit of the present invention should be understood solely by the claims set forth below, and all equivalent or equivalent modifications thereof are deemed to fall within the scope of the present invention.
