Description

Technical Field

[0001] This utility model relates to the field of gastrostomy technology, and more specifically, to a button-type gastrostomy tube. Background Technology

[0002] Gastrostomy is a medical and nursing technique that involves percutaneous placement of a gastrostomy tube under endoscopic guidance to achieve enteral nutrition. It is primarily suitable for patients who are unable to eat independently for various reasons and require long-term nutritional support, such as those with swallowing dysfunction or those who are bedridden due to neurological disorders. Gastrostomy is simple to perform, safe, and has few complications, making it a commonly used nutritional support method in clinical practice.

[0003] However, many patients now go home to recuperate after undergoing gastrostomy. After prolonged use of the gastrostomy tube, the material may age (the tube body is prone to aging) and infection may occur (bacteria grow on the inner wall of the tube, causing infection). Therefore, the gastrostomy tube needs to be replaced regularly, which is inconvenient to go to the hospital for replacement multiple times. At the same time, the existing gastrostomy tubes are of fixed length. If the gastrostomy tube used on the patient is too long, it is difficult to fix and it is easy to get stuck. If there is any scraping, the tube can easily be pulled out, which will increase the risk of secondary injury.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a button-type gastrostomy tube with a detachable supply head and positioning sleeve at one end of the tube. This allows the gastrostomy tube to be suitable for different populations, while ensuring that the tube length is appropriate and preventing it from being scraped or pulled out during the process.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a button-type gastrostomy tube, comprising a tube body and a balloon fixedly disposed at one end of the tube body, a partition plate disposed inside the tube body, a feeding channel and a water inlet channel forming on both sides of the partition plate, the water inlet channel communicating with the balloon, a detachably connected supply component disposed at the end of the tube body away from the balloon, the supply component comprising a supply head inserted into the tube body and a positioning sleeve sleeved outside the tube body, the supply head being provided with a positioning tube communicating with the feeding channel and the water inlet channel, the positioning sleeve corresponding to the positioning tube, the difference between the inner diameter of the positioning sleeve and the outer diameter of the positioning tube being less than the thickness of the tube body wall.

[0007] Preferably, the positioning tube is provided with two mutually symmetrical fan-shaped pipes, which are respectively located in the feeding channel and the water inlet channel. The gap between the two fan-shaped pipes has a trapezoidal cross section, and the gap between the ends of the two fan-shaped pipes is less than the thickness of the partition plate.

[0008] Preferably, the positioning sleeve end has a plurality of positioning plates arranged in a ring array, and the plurality of positioning plates are provided with a retaining plate arranged radially along the positioning sleeve, and the positioning tube end has a retaining groove corresponding to the retaining plate.

[0009] Preferably, the supply head is provided with a food inlet and a water inlet that are respectively connected to two fan-shaped pipes, and a cover plate for sealing the food inlet is provided on one side of the supply head.

[0010] Preferably, the positioning sleeve is fitted with an annular baffle that slides along its length.

[0011] Preferably, the positioning sleeve is provided with a toothed snap-fit ​​groove, the toothed cross section of the snap-fit ​​groove is a right-angled triangle, the annular baffle is provided with an extension plate corresponding to the snap-fit ​​groove, and the extension plate is provided with a snap-fit ​​plate corresponding to the snap-fit ​​groove.

[0012] In summary, this utility model has the following beneficial effects: 1) When it is necessary to replace the gastrostomy tube, medical staff remove the gastrostomy tube used on the patient, measure its length, and then cut the new tube to the same length as the used one. Then, the positioning sleeve is put on the tube, and the positioning tube of the supply head is inserted into the tube, so that the positioning tube is connected to the feeding channel and the water channel. Then, the tube is placed between the positioning sleeve and the positioning tube. Since the difference between the inner diameter of the positioning sleeve and the outer diameter of the positioning tube is less than the thickness of the tube wall, the tube wall is compressed, thereby achieving a sealing effect. The tube is then inserted into the patient's body. Due to the partition plate inside the tube, the tube is divided into the feeding channel and the water channel. Water is supplied to the water channel through the supply head, causing the balloon to inflate, thereby fixing the gastrostomy tube to the patient.

[0013] 2) Because the cross-section of the gap between the two sector tubes is trapezoidal, and the gap between the ends of the two sector tubes is less than the thickness of the partition plate, when the partition plate is set between the two sector tubes, the two sector tubes squeeze the partition plate to form a seal. At the same time, medical staff inject water into the water inlet through the water inlet, so that the balloon can expand and food can be injected into the feeding channel through the feeding inlet.

[0014] 3) The positioning sleeve and the positioning tube are connected by a number of positioning plates with corresponding slots, so that the positioning sleeve and the positioning tube are mutually restrained to prevent them from falling off.

[0015] 4) An annular baffle that slides along the length of the positioning sleeve is provided so that after the gastrostomy tube is installed on the patient's body, the annular baffle can be slid close to the patient's skin to fix the gastrostomy tube. At the same time, the toothed locking groove can support the locking plate on the extension plate to prevent the annular baffle from sliding back and forth. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A button-type gastrostomy tube, such as Figures 1 to 4 As shown, the device includes a tube body 1 and a balloon 2 fixedly installed at one end of the tube body 1. A partition plate 3 is provided inside the tube body 1, and a feeding channel 4 and a water inlet channel 5 are formed on both sides of the partition plate 3. The water inlet channel 5 is connected to the balloon 2. A detachable supply component 6 is provided at the end of the tube body 1 away from the balloon 2. The supply component 6 includes a supply head 7 inserted into the tube body 1 and a positioning sleeve 8 sleeved outside the tube body 1. The supply head 7 is provided with a positioning tube 9 that is connected to the feeding channel 4 and the water inlet channel 5. The positioning sleeve 8 corresponds to the positioning tube 9, and the difference between the inner diameter of the positioning sleeve 8 and the outer diameter of the positioning tube 9 is less than the thickness of the wall of the tube body 1.

[0020] As described above, in practical applications, when it is necessary to replace the gastrostomy tube, medical staff remove the gastrostomy tube used on the patient's body, measure the length of its tube body 1, and then directly cut the new tube body 1 to the same length as the used tube body 1. Then, the positioning sleeve 8 is put on the tube body 1, and the positioning tube 9 of the supply head 7 is inserted into the tube body 1, so that the positioning tube 9 is connected to the feeding channel 4 and the water inlet channel 5. Then, the tube body 1 is placed between the positioning sleeve 8 and the positioning tube 9. Since the difference between the inner diameter of the positioning sleeve 8 and the outer diameter of the positioning tube 9 is less than the thickness of the tube body 1 wall, the tube body 1 wall is compressed, thereby achieving a sealing effect. The tube body 1 is inserted into the patient's body. Due to the partition plate 3 inside the tube body 1, the tube body 1 is divided into the feeding channel 4 and the water inlet channel 5. Water is supplied to the water inlet channel 5 through the supply head 7, causing the balloon 2 to inflate, thereby fixing the gastrostomy tube to the patient.

[0021] According to the above embodiment, it is further configured as follows: the positioning tube 9 is provided with two mutually symmetrical fan-shaped through pipes 10, the two fan-shaped through pipes 10 are respectively set in the feeding channel 4 and the water inlet channel 5, the gap between the two fan-shaped through pipes 10 has a trapezoidal cross section, and the gap between the ends of the two fan-shaped through pipes 10 is less than the thickness of the partition plate 3. The supply head 7 is provided with a feeding inlet 14 and a water inlet 15 respectively communicating with the two fan-shaped through pipes 10, and a cover plate 16 for sealing the feeding inlet 14 is provided on one side of the supply head 7.

[0022] As described above, in practical applications, since the gap between the two sector-shaped tubes 10 has a trapezoidal cross section and the gap between the ends of the two sector-shaped tubes 10 is less than the thickness of the partition plate 3, when the partition plate 3 is placed between the two sector-shaped tubes 10, the two sector-shaped tubes 10 squeeze the partition plate 3 to form a seal. At the same time, medical staff inject water into the water inlet channel 5 through the water inlet port 15, so that the balloon 2 can expand and inject food into the feeding channel 4 through the feeding inlet port 14.

[0023] According to the above embodiment, it is further configured that: the end of the positioning sleeve 8 has a plurality of positioning plates 11 arranged in a ring, and the plurality of positioning plates 11 are provided with a card plate 12 arranged radially along the positioning sleeve 8, and the end of the positioning tube 9 has a card groove 13 corresponding to the card plate 12.

[0024] As described above, in practical applications, the positioning sleeve 8 and the positioning tube 9 are connected by a number of positioning plates 11 with corresponding slots 13, so that the positioning sleeve 8 and the positioning tube 9 are mutually restrained to prevent them from falling off.

[0025] According to the above embodiment, it is further configured as follows: the positioning sleeve 8 is fitted with an annular baffle 17 that slides along its length direction, the positioning sleeve 8 is provided with a rack-shaped snap-fit ​​groove 18, the tooth cross section of the snap-fit ​​groove 18 is a right-angled triangle, the annular baffle 17 is provided with an extension plate 19 corresponding to the snap-fit ​​groove 18, and the extension plate 19 is provided with a snap-fit ​​plate 20 corresponding to the snap-fit ​​groove 18.

[0026] As described above, in practical applications, an annular baffle 17 that slides along the length of the positioning sleeve 8 is provided, so that after the gastrostomy tube is installed on the patient's body, the annular baffle 17 can be slid close to the patient's skin to fix the gastrostomy tube. At the same time, the toothed locking groove 18 can support the locking plate 20 on the extension plate 19 to prevent the annular baffle 17 from sliding back and forth.

[0027] In summary: When a gastrostomy tube needs to be replaced, medical staff remove the existing tube, measure its length (tube body 1), and then cut a new tube body 1 to the same length as the old one. A positioning sleeve 8 is then fitted onto the tube body 1, and the positioning tube 9 of the supply head 7 is inserted into the tube body 1, connecting it to the feeding channel 4 and the water channel 5. The tube body 1 is then positioned between the positioning sleeve 8 and the positioning tube 9. Because the difference between the inner diameter of the positioning sleeve 8 and the outer diameter of the positioning tube 9 is less than the thickness of the tube body 1 wall, the tube body 1 wall is compressed. Simultaneously, the cross-section of the gap between the two fan-shaped tubes 10 is trapezoidal. The tube body 1 is shaped such that the gap between the ends of the two fan-shaped tubes 10 is less than the thickness of the partition plate 3. When the partition plate 3 is placed between the two fan-shaped tubes 10, the two fan-shaped tubes 10 squeeze the partition plate 3 to form a seal. After the tube body 1 is inserted into the patient's body, the medical staff inject water into the water inlet 5 through the water inlet 15, so that the balloon 2 can expand. Food is injected into the feeding channel 4 through the feeding inlet 14 to feed the patient. This allows the gastrostomy tube to be adapted to different people. At the same time, after cutting, the tube body 1 is fixed together with the supply head 7, so that the length of the gastrostomy tube is appropriate and the tube body is prevented from being scraped and pulled out during the process.
