Description

Technical Field

[0001] The invention relates to the field of oral feeding devices, in particular to a capsule oral feeding device. Background Art

[0002] In clinical practice, there is a type of patient whose swallowing function has not been completely lost and who still has an interest in food. However, due to physical weakness or advanced age, they cannot complete a complete meal by relying on their own swallowing function. The usual practice is to place a gastric tube in such patients, but there are several disadvantages to placing a gastric tube: first, it will affect the patient's appearance and cause the patient to have appearance anxiety; second, it will block one side of the nasal cavity, causing discomfort and mouth breathing in the patient; third, long-term placement of a gastric tube will destroy the closing function of the epiglottis and the structure of the gastroesophageal junction, increasing the risk of reflux aspiration; fourth, it is not conducive to maintaining the patient's remaining swallowing function and cannot improve swallowing ability. With long-term placement of a gastric tube, the patient's swallowing function will gradually be lost, which may aggravate swallowing disorders.

[0003] Currently, some hospitals are trying to use oral feeding tubes. The tube is intermittently placed into the esophagus through the oral route as needed, and liquid nutrients are injected into the esophagus through the tube to provide nutritional support. However, existing oral feeding tubes are mostly made of polyurethane materials, and their shape and structure are similar to gastric tubes, but they are shorter and made of harder materials, which makes patients feel very uncomfortable during use.

[0004] To this end, we proposed a capsule oral feeding device. Summary of the invention

[0005] The invention provides a capsule oral feeding device.

[0006] To achieve the above object, the present invention provides the following technical solution: a capsule oral feeding device, comprising a first oral feeding injection tube, the first oral feeding injection tube is soft, one end of the first oral feeding injection tube is provided with an injection structure, and the other end of the first oral feeding injection tube is provided with a quick-dissolving capsule that can be swallowed into the esophagus by the patient;

[0007] The injection structure comprises a second oral feeding injection tube arranged at one end of the first oral feeding injection tube, and the second oral feeding injection tube is sleeved on the inner wall of the first oral feeding injection tube; when the patient has insufficient swallowing ability, the patient can swallow the instant capsule, so that when swallowing, the first oral feeding injection tube inside the instant capsule will unfold along the esophagus to form a channel, so as to facilitate the injection of liquid food and the patient's calorie intake. At the same time, because the first oral feeding injection tube is soft, when swallowing, the patient is more comfortable when using it compared with the existing oral feeding tube, thereby improving the patient's comfort.

[0008] Preferably, a first oral feeding injection tube is placed inside the instant capsule, the first oral feeding injection tube is evenly folded and placed inside the instant capsule, one end of the first oral feeding injection tube is connected to the inner wall of the instant capsule through a first connecting block, the other end of the first oral feeding injection tube passes through a groove and extends to one side of the instant capsule, and the groove is provided on the side wall of the instant capsule; after the patient swallows the instant capsule into the esophagus, the instant capsule will move along the esophagus under the action of gravity, and the first oral feeding injection tube will form a channel in the esophagus due to the injection of food, so as to facilitate the subsequent injection of liquid food into the patient's body.

[0009] Preferably, the inner wall of the groove is provided with a protrusion, which can reduce the friction between the first oral feeding tube and the protrusion when the first oral feeding tube extends out of the instant capsule, so that the first oral feeding tube can slide more conveniently on the inner wall of the groove.

[0010] Preferably, a second connection block is provided on one side of the raised portion close to the first oral feeding tube, and the second connection block is placed on the outer wall of the first oral feeding tube to fix the first oral feeding tube; when the instant capsule is swallowed into the esophagus, the liquid inside the esophagus will dissolve the second connection block, thereby separating the first oral feeding tube from the instant capsule; when the instant capsule continues to move, the first oral feeding tube can be pulled out from the inside of the instant capsule to form a channel in the esophagus, so as to facilitate the subsequent injection of liquid food.

[0011] Preferably, the first connecting block and the second connecting block are both made of soluble edible substances; when the first connecting block and the second connecting block come into contact with liquid, they can melt quickly, and the pungent taste produced during melting can improve the patient's compliance and pleasure.

[0012] Preferably, a guide head is fixedly mounted on one end of the second oral feeding tube close to the first oral feeding tube, and the guide head is arranged in an inclined shape; it can play a guiding role when the first oral feeding tube and the second oral feeding tube are connected together, and it is convenient to embed the guide head into the interior of the first oral feeding tube, so as to expand the first oral feeding tube, thereby facilitating the connection of the first oral feeding tube and the second oral feeding tube.

[0013] Preferably, an annular protrusion is fixedly installed on the outer wall of the second oral feeding injection tube, and an annular slider is arranged on the side of the annular protrusion away from the first oral feeding injection tube, and the annular slider is slidably installed on the outer wall of the second oral feeding injection tube; when the first oral feeding injection tube and the second oral feeding injection tube are connected, the first oral feeding injection tube can be stretched open so that the annular protrusion is embedded in the inner wall of the first oral feeding injection tube, and then the annular slider is pushed to one side of the annular protrusion, and the end of the first oral feeding injection tube is clamped between the annular protrusion and the annular slider, so that the first oral feeding injection tube and the second oral feeding injection tube are fixed, avoiding the problem that when injecting liquid food, since the first oral feeding injection tube is in a normal state, the liquid food will squeeze the first oral feeding injection tube and stretch the first oral feeding injection tube, and when the first oral feeding injection tube is stretched, resistance will be generated, thereby easily causing the first oral feeding injection tube to separate from the second oral feeding injection tube, thereby improving the stability of the device.

[0014] Preferably, the cross-sectional shape of the first oral feeding injection tube in a normal state is rectangular, and the cross-sectional shape of the first oral feeding injection tube in an open state is circular; when the cross-sectional shape is rectangular, the first oral feeding injection tube is similar to a rope and can be more conveniently passed through the esophagus, thereby avoiding the problem that the first oral feeding injection tube is circular when entering the esophagus, which may cause compression to the patient's esophagus and cause the patient to feel very uncomfortable during use, thereby improving the patient's comfort.

[0015] Preferably, the minimum distance between the two protrusions is greater than the distance between the two sides of the first oral feeding injection tube in a normal state; when the first oral feeding injection tube is unfolded, the liquid in the esophagus can enter the interior of the instant capsule along the gap between the first oral feeding injection tube and the protrusion, thereby contacting the first connecting block, so that the first connecting block is dissolved, and at the same time, the liquid enters the interior of the instant capsule, so that the contact surface between the liquid and the instant capsule is larger, thereby accelerating the dissolution rate of the instant capsule.

[0016] Preferably, the outer wall of one end of the instant capsule is sleeved with a capsule sleeve; before use, the capsule sleeve can be sleeved on the outer wall of the instant capsule, so as to protect the first oral feeding injection tube extending out of the outer wall of the instant capsule; when in use, the capsule sleeve is removed from one end of the instant capsule, and then the first oral feeding injection tube is connected to one end of the second oral feeding injection tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention enables the patient to swallow the instant capsule and the first oral feeding tube into the esophagus by himself with the remaining swallowing ability. After entering the esophagus, it expands to form a channel, and the fluid diet can be injected through this channel. When using it, the patient can first eat orally to satisfy the appetite and exercise the chewing and swallowing functions. After fatigue, the capsule oral feeding tube can be used to complete the calorie intake of the meal, thereby improving the comfort of the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-9 , a capsule oral feeding device is shown in the figure, including a first oral feeding injection tube 3, the first oral feeding injection tube 3 is soft, one end of the first oral feeding injection tube 3 is provided with an injection structure, and the other end of the first oral feeding injection tube 3 is provided with a quick-dissolving capsule 2 that can be swallowed into the esophagus by the patient, wherein the cross section of the first oral feeding injection tube 3 can be changed, and the first oral feeding injection tube 3 can exist in two states, the first is a normal state when there is no filler inside, the first oral feeding injection tube 3 is contracted as a whole, and the cross section of the first oral feeding injection tube 3 is a rectangle, and the second is when there is filler inside, it is also That is, when the liquid food is injected into the first oral feeding injection tube 3, the cross section of the first oral feeding injection tube 3 is circular. In addition, the first oral feeding injection tube 3 is soft, so it can be bent accordingly according to the different positions of the patient's esophagus. At the same time, when the first oral feeding injection tube 3 is placed inside the capsule sleeve 1 and the quick-dissolving capsule 2, it can also be folded inside the capsule sleeve 1 and the quick-dissolving capsule 2, so that the first oral feeding injection tube 3 can be stored inside the capsule sleeve 1 and the quick-dissolving capsule 2, so that the first oral feeding injection tube 3 can be swallowed by the patient along with the quick-dissolving capsule 2, and can also be unfolded after swallowing. , forming a channel for injecting liquid food, wherein the length of the first oral feeding injection tube 3 placed inside the quick-dissolving capsule 2 is 20-25CM, and this length can form a 20-25CM after the first oral feeding injection tube 3 is swallowed into the esophagus. This length is set according to the length of the human esophagus. Therefore, for special groups, such as children, a first oral feeding injection tube 3 with a length corresponding to the esophagus of children of different ages can be used. The length of the first oral feeding injection tube 3 placed inside the capsule sleeve 1 is 5-10CM. The length at this point is mainly to prevent the quick-dissolving capsule 2 from entering the esophagus. After the patient enters the esophagus, the end of the first feeding tube 3 can be in the patient's oral cavity, or outside the cavity, so as to facilitate the operation of injecting liquid food. The material of the quick-dissolving capsule 2 is made of gelatin, which can dissolve quickly, but will not dissolve just after being put into the oral cavity, which can well avoid the first feeding tube 3 inside the quick-dissolving capsule 2 from unfolding before entering the esophagus, resulting in the first feeding tube 3 not being able to smoothly enter the esophagus. The first feeding tube 3 is similar in softness to a balloon and similar in thickness to a plastic bag. The specific material can be selected according to actual conditions;

[0032] The injection structure includes a second oral feeding injection tube 7 arranged at one end of the first oral feeding injection tube 3. The second oral feeding injection tube 7 is sleeved on the inner wall of the first oral feeding injection tube 3. Liquid food can be injected into the first oral feeding injection tube 3 through the second oral feeding injection tube 7, thereby entering the esophagus, so that the patient can be injected with liquid food when he / she has no swallowing ability, thereby ensuring the patient's daily calorie intake;

[0033] In this embodiment, when the patient's swallowing ability is insufficient, the patient can swallow the instant capsule 2, so that when swallowing, the first oral feeding injection tube 3 inside the instant capsule 2 will expand along the esophagus to form a channel, so as to facilitate the injection of liquid food and the patient's intake of calories. At the same time, because the first oral feeding injection tube 3 is soft, when swallowing, the patient is more comfortable when using it compared with the existing oral feeding tube, avoiding the problem that the patient is very uncomfortable during the use of the existing oral feeding tube because the oral feeding tube is a tube with a shape and structure similar to the gastric tube, but is shorter than the gastric tube and is made of a harder material, thereby improving the patient's comfort.

[0034] See also Figure 3-6 In the figure, a first oral feeding injection tube 3 is placed inside the instant capsule 2. The first oral feeding injection tube 3 is evenly folded and placed inside the instant capsule 2. One end of the first oral feeding injection tube 3 is connected to the inner wall of the instant capsule 2 through a first connecting block 8. The other end of the first oral feeding injection tube 3 passes through a groove 10 and extends to one side of the instant capsule 2. The groove 10 is provided on the side wall of the instant capsule 2. The first oral feeding injection tube 3 is folded in the instant capsule 2. The drawings in the specification are only one embodiment. The specific folding method can be the folding method shown in the figure, or other methods can be used, such as circling inside the instant capsule 2, or other methods can be used.

[0035] In this embodiment, after the patient swallows the instant capsule 2 into the esophagus, the instant capsule 2 will move along the esophagus under the action of gravity. When the instant capsule 2 moves, it will pull the first oral feeding injection tube 3 to move downward. At this time, the liquid secreted in the patient's oral cavity will dissolve the second connecting block 11. Therefore, when the instant capsule 2 moves downward, it will drive the first oral feeding injection tube 3 to move downward, and pull the first oral feeding injection tube 3 inside the instant capsule 2, so that the first oral feeding injection tube 3 inside the instant capsule 2 moves to the instant capsule 2. The first oral feeding injection tube 3 will form a passage in the esophagus due to the injection of food. When the first oral feeding injection tube 3 inside the instant capsule 2 is completely pulled out, the liquid inside the patient's body will enter the inside of the instant capsule 2 along the groove 10, causing the first connecting block 8 to melt, thereby disconnecting the first oral feeding injection tube 3 from the instant capsule 2. The instant capsule 2 continues to enter the patient's stomach under the action of gravity, and the first oral feeding injection tube 3 forms a passage inside the esophagus for injecting liquid food, which is convenient for injecting liquid food into the patient's body later.

[0036] Working principle: In the process of using the device, the capsule sleeve 1 is first removed from the outer wall of the instant capsule 2, and then the first oral feeding injection tube 3 inside the capsule sleeve 1 is unfolded, one end of the first oral feeding injection tube 3 is found, and one end of the first oral feeding injection tube 3 is opened, and then the guide head 4 is embedded into the inner wall of the first oral feeding injection tube 3, and the first oral feeding injection tube 3 is expanded so that the first oral feeding injection tube 3 wraps the annular protrusion 5, and then the annular slider 6 is pushed to make the annular slider 6 slide along the outer wall of the second oral feeding injection tube 7 until the annular slider 6 clamps the first oral feeding injection tube 3 between the annular protrusion 5 and the annular slider 6, thereby fixing the first oral feeding injection tube 3 and the second oral feeding injection tube 7 together, and then the patient is allowed to swallow the instant capsule 2. When the instant capsule 2 is swallowed into the esophagus, the first oral feeding injection tube 3 will be driven into the esophagus. At this time, the liquid in the esophagus will contact the second connecting block 11, so that the second connecting block 11 is dissolved, so that the first oral feeding injection tube 3 and the instant capsule 2 are connected. When the first oral feeding tube 3 is pulled, the instant capsule 2 moves downward along the esophagus, thereby pulling the first oral feeding tube 3 out of the instant capsule 2. When the first oral feeding tube 3 is pulled, the instant capsule 2 moves downward until the instant capsule 2 moves to the patient's stomach. At this time, the first oral feeding tube 3 forms a channel in the patient's esophagus. At this time, only the first connecting block 8 is connected between the instant capsule 2 and the first oral feeding tube 3. However, during the process of the first oral feeding tube 3 being drawn out from the interior of the instant capsule 2, the liquid in the esophagus will enter the interior of the instant capsule 2 along the groove 10. On the basis of accelerating the melting of the instant capsule 2, the liquid can also contact the first connecting block 8, causing the first connecting block 8 to melt, thereby causing the instant capsule 2 to be separated from the first oral feeding tube 3. Finally, the liquid food is injected into the second oral feeding tube 7. The liquid food will enter the patient's stomach along the second oral feeding tube 7 and the first oral feeding tube 3 to provide the patient with daily calorie intake.

[0037] After the feeding is completed, the second oral feeding injection tube 7 can be pulled so that the second oral feeding injection tube 7 drives the first oral feeding injection tube 3 to be detached from the patient's esophagus, and then the entire device is treated as medical waste.

[0038] Example 2

[0039] See also Figure 3 and Figure 8 This embodiment further explains Example 1. In the figure, a protrusion 9 is provided on the inner wall of the groove 10. The cross section of the protrusion 9 is an arc. The arc can be a circular arc or other arcs. It only needs to ensure that the contact surface between the protrusion 9 and the first oral feeding tube 3 is an arc surface.

[0040] In this embodiment, when the first oral feeding injection tube 3 extends out of the instant capsule 2, the friction between the first oral feeding injection tube 3 and the protrusion 9 can be reduced, so that the first oral feeding injection tube 3 can slide on the inner wall of the groove 10 more conveniently.

[0041] See also Figure 3 and Figure 8 In the figure, a second connection block 11 is provided on one side of the raised portion 9 close to the first oral feeding tube 3. The second connection block 11 is placed on the outer wall of the first oral feeding tube 3 to fix the first oral feeding tube 3. The second connection block 11 mainly fixes the first oral feeding tube 3 and the quick-dissolving capsule 2. At the same time, when entering the patient's body, the second connection block 11 can be dissolved to loosen the first oral feeding tube 3 and the quick-dissolving capsule 2, so that the first oral feeding tube 3 can be easily separated from the inside of the quick-dissolving capsule 2.

[0042] In this embodiment, when the fast-dissolving capsule 2 is swallowed into the esophagus, the liquid inside the esophagus will dissolve the second connecting block 11, so that the first oral feeding injection tube 3 is separated from the fast-dissolving capsule 2. When the fast-dissolving capsule 2 continues to move, the first oral feeding injection tube 3 can be pulled out from the inside of the fast-dissolving capsule 2 to form a channel in the esophagus, which is convenient for the subsequent injection of liquid food.

[0043] See also Figure 4 , Figure 5 and 8 In the figure, the first connecting block 8 and the second connecting block 11 are both made of soluble edible substances; the specific material needs to be selected according to the patient's physical condition. Preferably, the first connecting block 8 and the second connecting block 11 can add different edible flavors that stimulate the taste buds. The addition of the flavor can be selected according to the patient's taste. At the same time, the material for producing the flavor also needs to be adjusted according to the patient's actual situation to avoid the flavor material causing other effects on the patient's body.

[0044] In this embodiment, the first connecting block 8 and the second connecting block 11 can melt quickly when they come into contact with liquid, and the pungent smell produced when melting can improve the patient's compliance and pleasure.

[0045] See also Figure 2 and Figure 7 In the figure, the cross-sectional shape of the first feeding injection tube 3 in a normal state is rectangular, and the cross-sectional shape of the first feeding injection tube 3 in an open state is circular; when the cross-sectional shape is rectangular, the first feeding injection tube 3 is similar to a rope, and can enter the esophagus more conveniently, avoiding the problem that the first feeding injection tube 3 is circular when entering the esophagus, which will cause compression to the patient's esophagus and make the patient very uncomfortable during use, thereby improving the patient's comfort.

[0046] See also Figure 8 In the figure, the minimum distance between the two protrusions 9 is greater than the distance between the two sides of the first oral feeding injection tube 3 in a normal state; when the first oral feeding injection tube 3 is unfolded, the liquid in the esophagus can enter the interior of the instant capsule 2 along the gap between the first oral feeding injection tube 3 and the protrusion 9, thereby contacting the first connecting block 8, so that the first connecting block 8 is dissolved, and at the same time, the liquid enters the interior of the instant capsule 2, so that the contact surface between the liquid and the instant capsule 2 is larger, thereby accelerating the dissolution speed of the instant capsule 2.

[0047] See also Figure 1 and Figure 3 In the figure, the outer wall of one end of the instant capsule 2 is sleeved with a capsule sleeve 1; before use, the capsule sleeve 1 can be sleeved on the outer wall of the instant capsule 2, so as to protect the first oral feeding injection tube 3 extending out of the outer wall of the instant capsule 2. When in use, the capsule sleeve 1 is removed from one end of the instant capsule 2, and then the first oral feeding injection tube 3 is connected to one end of the second oral feeding injection tube 7.

[0048] Example 3

[0049] See also Figure 2 , Figure 4 and Figure 7 In the figure, a guide head 4 is fixedly installed at one end of the second feeding injection tube 7 close to the first feeding injection tube 3, and the guide head 4 is arranged in an inclined shape; it can play a guiding role when the first feeding injection tube 3 and the second feeding injection tube 7 are connected together, and it is convenient to embed the guide head 4 into the inside of the first feeding injection tube 3, so as to open the first feeding injection tube 3, thereby facilitating the connection of the first feeding injection tube 3 and the second feeding injection tube 7 together.

[0050] See also Figure 2 , Figure 4 and Figure 7In the figure, an annular protrusion 5 is fixedly installed on the outer wall of the second oral feeding injection tube 7, and an annular slider 6 is arranged on the side of the annular protrusion 5 away from the first oral feeding injection tube 3. The annular slider 6 is slidably installed on the outer wall of the second oral feeding injection tube 7; when the first oral feeding injection tube 3 is connected to the second oral feeding injection tube 7, the first oral feeding injection tube 3 can be opened, so that the annular protrusion 5 is embedded in the inner wall of the first oral feeding injection tube 3, and then the annular slider 6 is pushed to one side of the annular protrusion 5, and the end of the first oral feeding injection tube 3 is clamped between the annular protrusion 5 and the annular slider 6, so that the first oral feeding injection tube 3 and the second oral feeding injection tube 7 are fixed, avoiding that when injecting liquid food, because the first oral feeding injection tube 3 is in a normal state, the liquid food will squeeze the first oral feeding injection tube 3 and open the first oral feeding injection tube 3, and when the first oral feeding injection tube 3 is opened, resistance will be generated, which will easily cause the first oral feeding injection tube 3 to separate from the second oral feeding injection tube 7, thereby improving the stability of the device.
