Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable suction conversion joint. Background Art

[0002] The disposable suction connecting tube is an auxiliary consumable specially designed for connecting nasogastric tubes and other medical devices in medical environments. It is usually used to connect nasogastric tubes and suction devices to suction the accumulated fluid, food residue or gas in the patient's stomach or esophagus when necessary.

[0003] However, after the existing disposable suction connecting tube is connected to the gastric tube, it cannot be connected to the syringe again, which causes inconvenience for patients with gastric retention or active bleeding before or during gastroscopy. At the same time, the fixing effect of the connecting tube and the gastric tube is not good, and the tubes are easily detached, which makes it difficult to meet the usage requirements.

After the combination part is completely connected with the gastric tube, the limiting ball can be reset and enter the positioning groove, and the first limiting ring can enter the first limiting groove, so that a good fastening effect can be provided for the gastric tube and the conversion joint after being connected. At the same time, the first friction part can increase the connection between the gastric tube and the combination part. The friction force makes the connection more secure, and the side holes on the surface of the gastric tube can increase the surface area for gas exchange, which helps to distribute oxygen or air more evenly to the lower respiratory tract, improve the oxygen supply efficiency and gas exchange capacity. When the suction tube is connected to the conversion joint, the suction tube can be inserted into the top surface of the conversion joint, and at the same time, the inner wall of the limiting tube can contact the outer surface of the suction tube, so that the inside and outside of the suction tube can be tightened, and the second friction part can further increase the friction force, and the second limiting ring can enter the second limiting groove, so as to improve the limiting effect of the suction tube, ensuring that it is not easy to separate and fall off during use.

DETAILED DESCRIPTION

[0020] See also Figure 1-4 , a disposable suction conversion joint, comprising a suction tube 1 and a stomach tube 2, a conversion joint 3 is arranged above the stomach tube 2;

[0021] The conversion joint 3 is used to connect with the suction tube 1 and the stomach tube 2, and can also be connected to an external syringe, making it more convenient to use before and during gastroscopy.

[0022] The surface of the conversion joint 3 is connected with a connecting pipe 4, a combination part 5 is arranged below the conversion joint 3, a limiting pipe 6 is fixed above the surface of the conversion joint 3, a first friction part 7 is provided on the surface of the combination part 5, a first limiting ring 8 is fixed on the surface of the combination part 5, a plurality of receiving grooves 10 are provided on the surface of the combination part 5, a limiting ball 11 is slidably connected to the inner wall of the receiving groove 10, a first limiting groove 9 and a positioning groove 12 are provided on the inner wall of the stomach tube 2, a second friction part 15 is provided above the surface of the suction tube 1 and on the inner wall of the limiting tube 6, a second limiting ring 13 is fixed on the inner wall of the limiting tube 6, a second limiting groove 14 is provided on the surface of the suction tube 1, and a plurality of side holes 17 are provided on the surface of the stomach tube 2;

[0023] The connecting tube 4 is used to connect with the syringe, and the combination part 5 is used to connect with the gastric tube 2. When the combination part 5 enters the inner wall of the gastric tube 2, the limiting ball 11 can be squeezed and deformed and move toward the inside of the receiving groove 10. After the combination part 5 is completely connected with the gastric tube 2, the limiting ball 11 can be reset and enter the positioning groove 12, and the first limiting ring 8 can enter the first limiting groove 9, so as to provide a good fastening effect after the gastric tube 2 and the conversion joint 3 are connected. At the same time, the first friction part 7 can increase the friction force at the connection between the gastric tube 2 and the combination part 5, making the connection more firm, and the side hole on the surface of the gastric tube 2 17 can increase the surface area for gas exchange, help oxygen or air to be more evenly distributed to the lower respiratory tract, improve oxygen supply efficiency and gas exchange capacity, when the suction tube 1 is connected to the conversion joint 3, the suction tube 1 can be inserted into the top surface of the conversion joint 3, and at the same time, the inner wall of the limiting tube 6 can contact the outer surface of the suction tube 1, so that the inside and outside of the suction tube 1 can be tightened, and the second friction portion 15 can further increase the friction force, and the second limiting ring 13 can enter the second limiting groove 14, so as to improve the limiting effect of the suction tube 1 and ensure that it is not easy to separate and fall off during use.

[0024] Furthermore, the first friction portion 7 and the second friction portion 15 are both provided with annular tooth structures;

[0025] The serrated pattern can increase the contact area and bite force, thereby improving the connection effect between the gastric tube 2 and the conversion joint 3. At the same time, the serrated pattern can resist loosening caused by vibration by increasing the contact friction, thereby improving the shock resistance of the gastric tube 2 and the conversion joint 3 after connection.

[0026] Furthermore, a limiting portion 16 is provided on the inner wall of the receiving groove 10, and the limiting ball 11 is made of rubber;

[0027] The setting of the limiting portion 16 can block the limiting ball 11, making it difficult for it to escape from the storage slot 10, and setting the limiting portion 16 to be made of rubber material ensures that it can be compressed and deformed.

[0028] Furthermore, the receiving grooves 10 and the limiting balls 11 are distributed in a circular array on the surface of the combination part 5, and the number and position of the positioning grooves 12 are adapted to the limiting balls 11;

[0029] The provision of a plurality of receiving grooves 10 and limiting balls 11 means that the stomach tube 2 and the conversion joint 3 can be better fastened after being connected, so that the stomach tube 2 and the conversion joint 3 are not easy to be separated.

[0030] Furthermore, a flaring guide portion is provided at the top of the stomach tube 2;

[0031] The provision of the flaring guide portion can reduce the difficulty of connecting the conversion joint 3 with the stomach tube 2 , making it easier to place the combination portion 5 into the stomach tube 2 .

[0032] Furthermore, the first limiting ring 8 and the second limiting ring 13 are both made of medical silicone;

[0033] Medical silica gel has excellent biocompatibility and is soft. It can ensure that the first limiting ring 8 and the second limiting ring 13 can be deformed while reducing the occurrence of rejection reactions.

[0034] Furthermore, the side holes 17 are distributed on the surface of the stomach tube 2 in a circular array;

[0035] The circular distribution can ensure that the nutrient solution is more evenly distributed to the esophagus and stomach, reducing the discomfort caused by concentrated inflow and promoting digestion and absorption.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
