Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a spiral connector for a nasogastric explosion-proof tube. Background Art

[0002] Nasogastric tube feeding is a method of delivering nutrients to the stomach through the nasal cavity. It is often used for patients who cannot take food orally or cannot eat normally. The nasogastric tube feeding operation process includes preparation, nasogastric tube insertion, confirmation of position, feeding, and ending the operation. The original operation is to first grind the food with a grinder, connect the stomach tube connector to the feeding port with a syringe, and after the connection is firm, manually pressurize the push rod piston to pump water and food into the patient's stomach to help patients who cannot swallow independently provide water and food to maintain metabolism, weight and nutrition in the body.

[0003] In order to save medical costs, syringes are generally used multiple times. After being used multiple times, the connection between the syringe and the nasogastric tube is prone to become slippery due to contact with grease. When the food is thick, the syringe needs to be pushed vigorously, which can easily cause the connection between the nasogastric tube and the injection tube to fall off. This not only increases the difficulty of feeding for the operator, but also causes food contamination and waste, and increases the patient's fear of eating during the retention period. In addition, after repeated feedings, the stopper on the connecting head of the nasogastric tube becomes unstable and easy to loosen due to food grease residue. Utility Model Content

[0004] The utility model aims to provide a nasogastric explosion-proof tube spiral connector which can prevent the tube from falling off and food from leaking during nasogastric tube feeding and can firmly close the nasogastric tube.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] The spiral connector of the explosion-proof tube for nasogastric feeding comprises a connecting tube and an abutment block. The upper surface of the connecting tube is provided with a groove, the inner wall of the groove is provided with an external thread, the outer surface of the groove is provided with a side block, the bottom of the side block is provided with a slot, the outer surface of the abutment block is connected with an insertion rod, and the insertion rod is adapted to the slot. The outer surface of the insertion rod is provided with arc-shaped teeth, and the outer side of the side block is provided with a fixing mechanism fixedly matched with the arc-shaped teeth.

[0007] It can be seen that by pressing the abutment block against the lower end of the connecting tube of the nasofeeding tube and inserting the insertion rod into the slot, the insertion rod is fixed by the fixing mechanism on the arc-shaped teeth, so that the nasofeeding tube and the connecting tube maintain a stable connection state and will not fall off, and the upper end of the nasofeeding tube connecting head is tightly abutted against the outer surface of the connecting tube, which can also play a sealing role. Subsequently, the connector of the spiral syringe is tightened with the external thread to ensure the stable connection of the spiral syringe, thereby avoiding the tube from falling off and food leakage during nasofeeding tube feeding.

[0008] Furthermore, the fixing mechanism includes a U-shaped plate installed on the outer surface of the side block, a slide plate is slidably installed on the inner side of the U-shaped plate, a guide rod is connected to the outer surface of one side of the slide plate, and the end of the guide rod passes through the outer side of the U-shaped plate, a spring is sleeved on the outer surface of the guide rod, and the two ends of the spring are respectively abutted against the inner walls of the slide plate and the U-shaped plate, and an arc-shaped tooth block is installed on the other side of the slide plate, and the end of the arc-shaped tooth block passes through the interior of the slot.

[0009] When the insertion rod is inserted into the slot, the arcuate surface on the arcuate tooth contacts and squeezes the arcuate surface at the end of the arcuate tooth block, thereby driving the arcuate tooth block to move sideways and push the slide plate to compress the spring. When the abutment block abuts against the connecting tube of the nasogastric tube, the insertion rod can be directly loosened, and the arcuate tooth block is inserted between the two arcuate teeth under the push of the spring. The plane on the lower side of the arcuate tooth abuts against the plane on the upper side of the arcuate tooth block, so that the insertion rod cannot be pulled out and can only move deeper into the slot for unidirectional movement, thereby achieving the purpose of fixing the insertion rod.

[0010] Furthermore, a connecting belt is connected to the outer surface of the connecting pipe, a sealing cap is arranged at the end of the connecting belt, and an internal thread is arranged on the inner wall of the sealing cap.

[0011] After feeding, tighten the sealing cap onto the external thread. Through the threaded connection, the nasogastric tube can be firmly closed to avoid loosening.

[0012] Furthermore, a mounting rod is installed on the outer surface of the sealing cap, a sleeve is sleeved on the outer surface of the mounting rod, and the sleeve is connected to the connecting belt.

[0013] By arranging the mounting rod and the collar, when the sealing cap is tightened on the external thread, the mounting rod rotates inside the collar, thereby preventing the connection belt from twisting.

[0014] Furthermore, four silicone rings are evenly arranged on the outer surface of the lower end of the connecting pipe.

[0015] When the lower end of the connecting tube is inserted into the connecting head of the nasogastric tube, the silicone ring can fill the gap between the connecting tube and the inner wall of the connecting head to achieve a sealing effect, thereby further reducing food leakage.

[0016] Furthermore, a pull block is installed at the end of the guide rod.

[0017] By setting the pulling block, it is convenient to pull the guide rod outwards and drive the arc-shaped tooth block to move, so that the insertion rod can be smoothly drawn out of the slot. BRIEF DESCRIPTION OF THE DRAWINGS

The upper surface of the connecting tube 100 is provided with a groove 101, and the inner wall of the inner side of the groove 101 is provided with an external thread 102. The outer surface of the groove 101 is installed with a side block 103, and the bottom of the side block 103 is provided with a slot 104. The outer surface of the abutment block 105 is connected with a plug rod 106, and the plug rod 106 is adapted to the slot 104. The outer surface of the plug rod 106 is provided with arc teeth 107, and the outer side of the side block 103 is provided with a fixing mechanism 200 fixedly matched with the arc teeth 107.

[0025] When in use, first insert the lower end of the connecting tube 100 into the connecting head of the nasogastric tube, and then insert the insertion rod 106 into the slot 104, so that the abutment block 105 is tightly pressed against the connecting head of the nasogastric tube, and the arc-shaped teeth 107 are fixedly matched by the fixing mechanism 200 to fix the insertion rod 106, so that the nasogastric tube and the connecting tube 100 maintain a stable connection state and will not fall off. Then use the spiral syringe to extract food, and then tighten the joint of the spiral syringe with the external thread 102 to ensure the stable connection of the spiral syringe. Push the piston of the spiral syringe to push the food into the nasogastric tube, avoiding the tube from coming off and food leakage during nasogastric tube feeding.

[0026] Specifically, the fixing mechanism 200 includes a U-shaped plate 201 installed on the outer surface of the side block 103, a slide plate 202 is slidably installed on the inner side of the U-shaped plate 201, a guide rod 203 is connected to the outer surface of one side of the slide plate 202, and the end of the guide rod 203 passes through the outer side of the U-shaped plate 201, and a spring 204 is sleeved on the outer surface of the guide rod 203, and the two ends of the spring 204 are respectively abutted against the inner walls of the slide plate 202 and the U-shaped plate 201, and an arc-shaped tooth block 205 is installed on the other side of the slide plate 202, and the end of the arc-shaped tooth block 205 passes through the interior of the slot 104. When the insertion rod 106 is inserted into the slot 104, the arc-shaped tooth block 205 is inserted into the slot 104. The arcuate surface on the tooth 107 contacts and squeezes the arcuate surface at the end of the arcuate tooth block 205, thereby driving the arcuate tooth block 205 to move sideways and push the slide plate 202 to compress the spring 204. When the abutment block 105 abuts against the connecting tube of the nasogastric tube, the insertion rod 106 can be directly loosened, and the arcuate tooth block 205 is inserted between the two arcuate teeth 107 under the push of the spring 204. The plane on the lower side of the arcuate tooth 107 abuts against the plane on the upper side of the arcuate tooth block 205, so that the insertion rod 106 cannot be pulled out and can only move unidirectionally into the slot 104, thereby achieving the purpose of fixing the insertion rod 106.

[0027] Specifically, the outer surface of the connecting tube 100 is connected to a connecting belt 300, and a sealing cap 301 is provided at the end of the connecting belt 300. The inner wall of the sealing cap 301 is provided with an internal thread 302. After feeding, the sealing cap 301 is tightened onto the external thread 102.

Through the arrangement of the mounting rod 400 and the ring 401, when the sealing cap 301 is tightened on the external thread 102, the mounting rod 400 can be rotated inside the ring 401 to avoid twisting of the connecting belt 300.

[0029] Specifically, four silicone rings 500 are evenly arranged on the outer surface of the lower end of the connecting tube 100. When the lower end of the connecting tube 100 is inserted into the connecting head of the nasogastric tube, the silicone ring 500 can fill the gap between the connecting tube 100 and the inner wall of the connecting head to achieve a sealing effect and further reduce food leakage.

[0030] Specifically, a pull block 600 is installed at the end of the guide rod 203 . The pull block 600 facilitates the guide rod 203 to be pulled outward and drives the arc-shaped tooth block 205 to move, so that the insertion rod 106 can be smoothly drawn out of the slot 104 .
