Description

Technical Field

[0001] This utility model relates to the field of devices for feeding food or oral medication, and in particular to a visual gastric tube. Background Technology

[0002] A gastric tube is a medical device used in special circumstances to help patients who cannot swallow to deliver necessary water and food. It is widely used in clinical practice for procedures such as gastrointestinal decompression, nutritional support, and drug administration. The retention time of gastric tubes varies depending on the material. Among them, polyurethane gastric tubes, with their good biocompatibility and durability, allow them to remain in the patient's body for approximately 2-3 months.

[0003] However, in actual use, liquid food delivered to patients through a gastric tube usually has a certain viscosity, which makes it easy for food to stick to the inner wall of the gastric tube, increasing the risk of microbial growth and potentially affecting the effectiveness of subsequent treatment. To solve this problem, the routine practice is to inject flushing water into the gastric tube to remove the adhered food residue.

[0004] However, because patients can only take in a limited amount of water each day, and the viscosity of liquid food decreases as the water content increases, even after rinsing, some food residue may still remain on the inner wall of the gastric tube. Utility Model Content

[0005] This invention provides a visible gastric tube to solve the problem that, due to the limited daily water intake of patients and the decrease in viscosity of liquid food with increasing water content, some food residue may still remain on the inner wall of the gastric tube even after rinsing.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0009] Furthermore, it also includes a drive mechanism; the drive mechanism includes a housing and a drive wheel; the housing is fitted onto the irrigation tube and slidably connected to the irrigation tube, and the outlet of the housing is connected to the inlet of the gastric tube; the drive wheel is rotatably mounted inside the housing and partially protrudes from the housing, the drive wheel abuts against the irrigation tube, and by rotating the drive wheel, the length of the irrigation tube extending out of the housing is changed.

[0010] Furthermore, the drive mechanism also includes a driven wheel; the driven wheel is rotatably mounted inside the housing and abuts against the drive wheel; the flushing pipe is located between the drive wheel and the driven wheel; the drive wheel drives the driven wheel to rotate, so that the flushing pipe moves along the housing.

[0012] Furthermore, the strip-shaped pressure regulating hole is inclined and includes an open end and a closed end; when the drive wheel is at the closed end, the drive wheel abuts against the driven wheel to clamp the flushing tube, thereby preventing the flushing water in the flushing tube from entering the gastric tube; when the drive wheel moves from the closed end to the open end, it gradually moves away from the driven wheel, so that the flushing tube gradually springs back, and the flow rate of the flushing water in the flushing tube gradually increases from small to large and flows into the gastric tube.

[0013] Furthermore, the strip-shaped pressure regulating hole is inclined and includes an open end and a flow-limiting end; when the drive wheel is located at the flow-limiting end, the drive wheel abuts against the driven wheel to compress the flushing tube, thereby causing the flushing water in the flushing tube to flow into the gastric tube at a set flow rate; when the drive wheel moves from the flow-limiting end to the open end, it gradually moves away from the driven wheel, causing the flushing tube to gradually spring back, thereby gradually increasing the flow rate of the flushing water flowing into the gastric tube in the flushing tube.

[0014] Furthermore, the drive mechanism also includes a guide pin; the guide pin is connected to the housing and located inside the housing, for guiding the flushing pipe to move within the housing.

[0015] Furthermore, the gastric tube includes a tube body and a feeding socket; one end of the tube body away from the human body is connected to the feeding socket; the drive mechanism also includes a connecting seat; one end of the connecting seat is connected to the housing, and the other end is inserted into the feeding socket; the connecting seat is fitted onto the rinsing tube and is slidably connected to the rinsing tube.

[0016] Furthermore, the drive mechanism also includes a lubrication sleeve; the lubrication sleeve is inserted into the housing and slidably fitted with the flushing pipe to reduce the friction between the flushing pipe and the housing.

[0017] Furthermore, the rinsing pipe is provided with multiple rinsing holes; all of the multiple rinsing holes are located on the side of the rinsing pipe and are arranged in a ring array around the axis of the rinsing pipe.

Detailed Implementation

[0029] Because patients can only take in a limited amount of water each day, and the viscosity of liquid food decreases as the water content increases, even after rinsing, some food residue may still remain on the inner wall of the gastric tube.

[0030] In view of this, this solution provides a visual gastric tube, including a gastric tube 100 and an irrigation mechanism 200.

[0031] The following combination Figures 1-5 A detailed description of the structure and shape of the visible gastric tube is provided:

[0032] The rinsing mechanism 200 includes a rinsing tube 210 and a camera component 220; the rinsing tube 210 is inserted into the gastric tube 100 and is slidably connected to the gastric tube 100; the camera component 220 is installed at the end of the rinsing tube 210 inserted into the gastric tube 100; the rinsing tube 210 drives the camera component 220 to move along the gastric tube 100 so that the camera component 220 can acquire images of the inner wall of the gastric tube 100 and confirm the location of the adhesive material, and then the rinsing tube 210 outputs rinsing water to peel off the adhesive material.

[0033] In this embodiment, the camera component 220 is moved along the gastric tube 100 by the flushing tube 210 so that the camera component 220 can acquire images of the inner wall of the gastric tube 100 and confirm the location of the adhesive material. Then, the flushing tube 210 outputs flushing water to peel off the adhesive material, effectively reducing the amount of water required to peel off the adhesive material.

[0034] To enable the acquisition of images of the inner wall of the gastric tube 100 by the imaging component 220 to confirm the location of the adhesion material:

[0035] The visual gastric tube also includes a display; the display is connected to a camera component 220; the camera component 220 transmits the acquired image of the inner wall of the gastric tube 100 to the display, and the operator confirms the location of the adhesive material on the inner wall of the gastric tube 100 based on the image on the display, and at the same time confirms the distance between the flushing tube 210 and the adhesive material.

[0036] In order to achieve the purpose of outputting flushing water from flushing pipe 210 to peel off the adhesive substances:

[0037] The visual gastric tube also includes a fluid supply device; the outlet of the fluid supply device is connected to the inlet of the flushing tube 210; the fluid supply device supplies constant pressure flushing water into the flushing tube 210.

[0038] To accommodate the flushing requirements of adhesive substances present at different angles on the inner wall cross-section of the gastric tube 100:

[0039] like Figure 3 As shown, the flushing pipe 210 has multiple flushing holes 211; the multiple flushing holes 211 are all located on the side of the flushing pipe 210 and are arranged in a ring array around the axis of the flushing pipe 210.

[0040] In this embodiment, multiple flushing holes 211 are opened on the side of the flushing tube 210, and the multiple flushing holes 211 are arranged in a ring array around the axis of the flushing tube 210. This allows the flushing water in the flushing tube 210 to be output through the flushing holes 211, so that the flushing tube 210 covers part of the cross-sectional area of ​​the inner wall of the gastric tube 100 in a static state. This adapts to the flushing requirements of adhesive substances at different angles on the cross-section of the inner wall of the gastric tube 100.

[0041] To drive the flushing mechanism 200 to move along the gastric tube 100:

[0042] like Figures 3-5 As shown, it also includes a drive mechanism 300; the drive mechanism 300 includes a housing 310 and a drive wheel 320; the housing 310 is fitted onto the rinsing tube 210 and is slidably connected to the rinsing tube 210, and the outlet of the housing 310 is connected to the inlet of the gastric tube 100; the drive wheel 320 is rotatably mounted inside the housing 310 and partially protrudes from the housing 310, and the drive wheel 320 abuts against the rinsing tube 210, and by rotating the drive wheel 320, the length of the rinsing tube 210 extending out of the housing 310 can be changed.

[0043] In this embodiment, the portion of the drive wheel 320 protruding from the housing 310 drives it to rotate along its own axis. The rotating drive wheel 320 drives the rinsing tube 210 to move, thereby changing the length of the rinsing tube 210 extending out of the housing 310, thus driving the rinsing mechanism 200 to move along the gastric tube 100.

[0044] To reduce the wear rate of the flushing pipe 210 as it passes through the drive wheel 320:

[0045] like Figures 4-5 As shown, the drive mechanism 300 also includes a driven wheel 330; the driven wheel 330 is rotatably mounted inside the housing 310 and abuts against the drive wheel 320; the flushing pipe 210 is located between the drive wheel 320 and the driven wheel 330; the drive wheel 320 drives the driven wheel 330 to rotate, so that the flushing pipe 210 moves along the housing 310.

[0046] In this embodiment, the drive wheel 320 drives the driven wheel 330 to rotate, thereby driving the flushing water located between the drive wheel 320 and the driven wheel 330 into the gastric tube 100 in order to control the flushing water in the flushing tube 210 to enter the gastric tube 100.

[0047] like Figure 5 As shown, a strip-shaped pressure regulating hole 311 is provided on the housing 310; the drive wheel 320 is inserted into the strip-shaped pressure regulating hole 311 and can move along the strip-shaped pressure regulating hole 311; the drive wheel 320 moves along the strip-shaped pressure regulating hole 311 to change the distance between the drive wheel 320 and the driven wheel 330.

[0048] In this embodiment, by driving the drive wheel 320 to move along the strip-shaped pressure regulating hole 311, the distance between the drive wheel 320 and the driven wheel 330 is changed, thereby changing the squeezing pressure received by the flushing tube 210, thus changing the effective diameter of the channel inside the flushing tube 210, so as to control the flushing water in the flushing tube 210 to enter the gastric tube 100.

[0049] The first embodiment of the strip-shaped pressure regulating orifice 311 is as follows:

[0050] like Figure 5 As shown, the strip-shaped pressure regulating hole 311 is inclined and includes an open end and a closed end; when the drive wheel 320 is at the closed end, the drive wheel 320 abuts against the driven wheel 330 to clamp the flushing tube 210, thereby preventing the flushing water in the flushing tube 210 from entering the gastric tube 100; when the drive wheel 320 moves from the closed end to the open end, it gradually moves away from the driven wheel 330, so that the flushing tube 210 gradually rebounds, and the flow rate of the flushing water in the flushing tube 210 gradually increases from small to large and flows into the gastric tube 100.

[0051] In this embodiment, when the drive wheel 320 is located at the closed end of the strip-shaped pressure regulating hole 311, the drive wheel 320 abuts against the driven wheel 330 to clamp the flushing tube 210, thereby preventing the flushing water in the flushing tube 210 from entering the gastric tube 100, thus controlling the flushing tube 210 to close.

[0052] When the drive wheel 320 moves from the closed end to the open end, the drive wheel 320 gradually moves away from the driven wheel 330, so that the flushing pipe 210 gradually rebounds under the action of flushing water pressure, thereby changing the effective diameter of the channel inside the flushing pipe 210, so that the flushing water flow rate inside the flushing pipe 210 gradually increases from small to large and flows into the gastric tube 100, thereby controlling the opening of the flushing pipe 210 while adjusting its output flushing water flow rate and pressure.

[0053] The second embodiment of the strip-shaped pressure regulating hole 311 is as follows:

[0054] like Figure 5As shown, the strip-shaped pressure regulating hole 311 is inclined and includes an open end and a flow-limiting end. When the drive wheel 320 is at the flow-limiting end, the drive wheel 320 abuts against the driven wheel 330 to compress the flushing tube 210, thereby causing the flushing water in the flushing tube 210 to flow into the gastric tube 100 at a set flow rate. When the drive wheel 320 moves from the flow-limiting end to the open end, it gradually moves away from the driven wheel 330, so that the flushing tube 210 gradually rebounds, thereby gradually increasing the flow rate of the flushing water flowing into the gastric tube 100 in the flushing tube 210.

[0055] In this embodiment, when the drive wheel 320 is at the flow-limiting end, the drive wheel 320 abuts against the driven wheel 330 to compress the flushing pipe 210, thereby causing the flushing water in the flushing pipe 210 to flow into the gastric tube 100 at a set flow rate. The flushing water flowing in the gastric tube 100 forms a wetting film between it and the flushing mechanism 200, thereby avoiding damage to the inner wall of the gastric tube 100 during the cleaning process.

[0056] When the drive wheel 320 moves from the flow-limiting end to the opening end, the drive wheel 320 gradually moves away from the driven wheel 330, so that the flushing pipe 210 gradually rebounds under the action of flushing water pressure, thereby changing the effective diameter of the channel inside the flushing pipe 210, so that the flow rate of flushing water flowing into the gastric tube 100 in the flushing pipe 210 gradually increases, thereby controlling the flushing pipe 210 to adjust the flow rate and pressure of the output flushing water.

[0057] To prevent the flushing tube 210 from curling inside the housing 310:

[0058] like Figure 5 As shown, the drive mechanism 300 also includes a guide pin 340; the guide pin 340 is connected to the housing 310 and located inside the housing 310, and is used to guide the flushing pipe 210 to move within the housing 310.

[0059] In this embodiment, the flushing tube 210 is guided and constrained to move within the housing 310 by the guide pin 340, thereby preventing the flushing tube 210 from curling within the housing 310 and reducing the probability of the moving flushing tube 210 getting stuck within the housing 310.

[0060] In order to connect the outlet of the housing 310 with the inlet of the gastric tube 100:

[0061] like Figure 2 and Figure 5 As shown, the gastric tube 100 includes a tube body 110 and a feeding socket 120; one end of the tube body 110 away from the human body is connected to the feeding socket 120; the drive mechanism 300 also includes a connecting seat 350; one end of the connecting seat 350 is connected to the housing 310, and the other end is inserted into the feeding socket 120. The connecting seat 350 is fitted onto the rinsing tube 210 and is slidably connected to the rinsing tube 210.

[0062] In this embodiment, when rinsing is required, the connector 350 is inserted into the feeding socket 120 so that the outlet of the housing 310 is connected to the inlet of the gastric tube 100, and then the connector 350 guides the rinsing tube 210 into the gastric tube 100; when the rinsing is completed, the connector 350 is pulled out from the feeding socket 120, and at the same time, the rinsing mechanism 200 is quickly pulled out from the gastric tube 100.

[0063] To reduce the wear rate of the flushing pipe 210 during its entry into the housing 310:

[0064] like Figure 5 As shown, the drive mechanism 300 also includes a lubrication sleeve 360; the lubrication sleeve 360 ​​is inserted into the housing 310 and slides in a sleeve with the flushing pipe 210 to reduce the friction between the flushing pipe 210 and the housing 310.

[0065] In this embodiment, the flushing pipe 210 enters the housing 310 through the lubrication sleeve 360. During this process, the lubrication sleeve 360 ​​reduces the friction force borne by the flushing pipe 210 through its own material properties. The material of the lubrication sleeve 360 ​​includes, but is not limited to, polytetrafluoroethylene.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
