Description

Technical Field

[0001] This utility model relates to the field of nasogastric tube technology, specifically to a nasogastric tube for postoperative care to prevent dislodgement. Background Technology

[0002] Most patients admitted to the Intensive Care Unit are those who have undergone surgery and require close monitoring. These patients are mostly unable to eat on their own and need to be fed through a nasogastric tube. Medical staff will then feed the patients nutritious liquid food or water directly into their stomachs through the tube to provide nutritional support and enhance their immunity.

[0003] Currently, most nasogastric tubes used in clinical practice are fixed by directly attaching them to the patient's face with tape. This method of fixation can easily tear the patient's facial skin, causing discomfort. Therefore, in clinical practice, an expandable element in a medical nasogastric tube fixation device (publication number CN204910148U) is also used for fixation by inserting it into the nostril. However, the position of the expandable element inserted into the nostril cannot be changed in this method, which makes it unsuitable for short nasogastric tubes and limits its application.

[0004] Furthermore, food often gets stuck in the inner wall of the nasogastric tube, which can easily cause blockage after prolonged use. Clinically, cleaning the nasogastric tube often requires removing it from the patient's body. Repeatedly inserting and removing the nasogastric tube can easily cause discomfort to the patient. Alternatively, water can be directly injected into the nasogastric tube, which can cause the patient to drink too much water and easily cause bloating. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a nasogastric tube for postoperative care to prevent dislodgement. It utilizes a ring-shaped balloon to restrict the position of the nasal plug on the outer wall of the outer tube, thereby adjusting the length of the outer tube inserted into the patient's body and expanding the scope of application. The balloon b seals the opening at the tail end of the inner tube, allowing the water filled inside the inner tube to flow out through the connector tube, thus cleaning the inner tube and preventing blockage. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a nasogastric tube for postoperative care of patients to prevent dislodgement, comprising a nasogastric tube body, wherein the nasogastric tube body comprises an outer tube and an inner tube with an opening at the tail end, the inner tube being disposed inside the outer tube, the tail end of the outer tube having multiple through holes a, and the end of the inner tube near the opening having multiple through holes b.

[0007] The nasogastric tube is provided with an insertion and fixing mechanism at its external end to fix the nasogastric tube body in the patient's body. The insertion and fixing mechanism includes a balloon a, which is fixed on the outer wall of the tail end of the outer tube. After the balloon a is inflated, it is stuck in the esophagus to fix the outer tube.

[0008] An air bladder b is fixed to the inner wall of the outer tube tail end. After the air bladder b is inflated, it squeezes the inner tube to seal the opening at the tail end of the inner tube. The clean water poured into the inner tube enters the space between the outer tube and the inner tube through the through hole b to clean the inner wall of the inner tube.

[0009] Preferably, the outer end of the outer tube is connected to a nasal plug for inserting into the patient's nostril, and a plurality of equally spaced annular airbags are fixed to the outer wall of the first end of the outer tube. After being inflated, the annular airbags are placed behind the nasal plug to restrict the position of the nasal plug and to fix the outer tube. The diameter of the inflated annular airbags is smaller than the inner diameter of the nostril, so they will not compress the nostril and cause discomfort to the patient.

[0010] Preferably, ear loops are fixed to both sides of the nasal plug, and an earring is fixed to the end of the ear loop away from the nasal plug. Both the ear loops and the earrings are made of rubber and are elastic and deformable.

[0011] Preferably, the top end of the outer tube is fixed with a tube connector for connecting a syringe;

[0012] The tube connector includes an outer connector fixed to the top of the outer tube, and an inner connector fixed inside the outer connector. The bottom end of the inner connector is connected to the top end of the inner tube for injecting food and water into the inner tube. The top end of the inner connector is plugged with a rubber stopper to seal the opening at the top end of the inner connector.

[0013] Preferably, a connector tube is fixed to both the front and rear sides of the external connector, the interior of the connector tube is connected to the cavity between the external connector and the internal connector, and a cap for sealing one end opening of the connector tube is threaded to the outer end of the connector tube.

[0014] Preferably, airbag a, annular airbag, and airbag b are all inflated via an inflation assembly. The inflation assembly includes an inflation tube a and an inflation tube b. One end of the inflation tube a and one end of the inflation tube b are inserted between an outer tube and an inner tube. The end of the inflation tube a inserted into the outer tube is connected to the interior of airbag a. The outer end of the inflation tube a is fixedly connected to a plurality of short tubes for inflating the annular airbag. The end of the inflation tube b inserted into the outer tube is connected to the interior of airbag b for inflating airbag b.

[0015] Preferably, both the end of the inflation tube a located outside the outer tube and the end of the inflation tube b located outside the outer tube are fixedly connected to an inflation connector. Both the outer ends of the inflation tube a and the outer ends of the inflation tube b are fitted with tube clamps. The inflation connectors can be easily connected to inflation equipment.

[0016] Preferably, the length of the inner tube is shorter than the length of the outer tube, and the liquid food flowing out through the opening at the tail end of the inner tube and through hole b passes through through hole a and enters the patient's stomach.

[0017] Compared with the prior art, this utility model provides a nasogastric tube for postoperative care to prevent dislodgement, which has the following beneficial effects:

[0018] 1. By using an annular airbag fixed to the outer wall of the outer tube to restrict the position of the nasal plug on the outer wall of the outer tube, the length of the outer tube inserted into the patient's body can be adjusted, making this utility model applicable to patients of different body types and expanding the scope of application of this utility model.

[0019] 2. By using the inflated air bladder b to block the opening at the end of the inner tube, the clean water filled in the inner tube can enter between the outer and inner tubes through the through hole b, and then flow out through the connector tube, thus achieving the effect of cleaning the inner wall of the inner tube and preventing blockage of the inner tube. At the same time, it will not cause the patient to drink too much water, achieving two goals at once. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] To address the shortcomings of existing technologies, such as Figure 1 As shown, this utility model provides a nasogastric feeding tube for postoperative care of patients to prevent dislodgement, including a nasogastric tube body 1. The nasogastric tube body 1 includes an outer tube 11 and an inner tube 12 with an opening at the tail end. The inner tube 12 is located inside the outer tube 11. The tail end of the outer tube 11 has multiple through holes a13. The end of the inner tube 12 near the opening has multiple through holes b14. The length of the inner tube 12 is shorter than the length of the outer tube 11, so that the liquid food flowing out through the tail end opening of the inner tube 12 and the through holes b14 can pass through the through holes a13 and enter the patient's stomach, achieving the effect of nasogastric feeding in clinical postoperative care.

[0033] A tube connector 2 for connecting a syringe is fixed to the top of the outer tube 11, specifically, as follows: Figure 3-5 As shown, the tube connector 2 includes an outer connector 21 fixed to the top of the outer tube 11. An inner connector 22 is fixed inside the outer connector 21. The bottom end of the inner connector 22 is connected to the top end of the inner tube 12. A rubber stopper 23 is inserted into the top end of the inner connector 22 to seal the opening at the top end of the inner connector 22. In use, by connecting the top end of the inner connector 22 to the syringe outlet, food and water are injected into the inner tube 12 using a syringe. The food and water then enter the inner tube 12 through the inner connector 22, and then enter the outer tube 11 through the opening and through hole b14 at the tail end of the inner tube 12. Finally, they enter the patient's stomach through the through hole a13 at the tail end of the outer tube 11. When not in use, the rubber stopper 23 can be directly inserted into the opening at the top end of the inner connector 22 for sealing.

[0034] After the nasogastric tube 1 is inserted into the patient's body through the patient's nostril, in order to prevent the nasogastric tube 1 from falling out, this utility model provides an insertion fixing mechanism 3 at the outer end of the nasogastric tube 1 to fix the nasogastric tube 1 in the patient's body.

[0035] The specific structure of the cannula fixing mechanism 3 is as follows: Figure 2-6The device includes an airbag a31, which is fixed to the outer wall of the tail end of the outer tube 11. A nasal plug 33 for inserting into the patient's nostril is inserted into the outer end of the outer tube 11. Ear loops 34 are fixed on both sides of the nasal plug 33, and an earring 35 is fixed to the end of the ear loop 34 away from the nasal plug 33. In use, first, the end of the outer tube 11 with the airbag a31 is passed through the patient's nostril and esophagus into the patient's stomach. Then, the nasal plug 33 is moved along the outer wall of the outer tube 11 until it is inserted into the patient's nostril. Then, the ear loop 35 is hung on the patient's ear. To further fix the position of the nasal plug 33, this utility model has multiple equally spaced annular airbags 32 fixed on the outer wall of the first end of the outer tube 11. Then, air is inflated into the airbag a31 so that it can be stuck in the esophagus to initially fix the outer tube 11. At the same time, air is inflated into the annular airbag 32 so that the inflated annular airbag 32 can block the back of the nasal plug 33, thereby restricting the position of the nasal plug 33. With the combined action of the ear loop 34 and the annular airbag 32, the position of the outer tube 11 is further fixed to achieve the effect of preventing it from falling off.

[0036] After use, food inevitably gets stuck to the inner wall of the inner tube 12. To ensure the cleanliness of the inner wall of the inner tube 12, such as... Figure 4-6 As shown, this utility model has an airbag b37 fixed to the inner wall of the tail end of the outer tube 11. Connector tubes 38 are fixed to both the front and rear sides of the outer connector 21. The interior of the connector tube 38 communicates with the cavity between the outer connector 21 and the inner connector 22. A cap 39 for sealing one end opening of the connector tube 38 is threaded to the outer end of the connector tube 38. When it is necessary to clean the inner wall of the inner tube 12, the cap 39 at the outer end of the connector tube 38 can be opened, and air can be inflated into the airbag b37. Located in front of through hole a13 and behind through hole b14, airbag b37, when inflated, can compress inner tube 12 to block the opening at the tail end of inner tube 12. Then, clean water poured into inner tube 12 through one end opening of inner connector 22 will enter between outer tube 11 and inner tube 12 through through hole b14, and then flow out through connector tube 38, achieving the effect of cleaning the inner wall of inner tube 12. At the same time, the cleaning water will not flow into the patient's stomach and will not cause the patient's stomach bloating.

[0037] During the above process, airbags a31, annular airbag 32, and airbag b37 are all inflated by the inflation assembly 36, the structure of which is as follows: Figure 4-6As shown: This includes an inflation tube a361 and an inflation tube b363. One end of the inflation tube a361 and one end of the inflation tube b363 are inserted between the outer tube 11 and the inner tube 12. The end of the inflation tube a361 inserted into the outer tube 11 communicates with the interior of the airbag a31. Multiple short tubes 362 for inflating the annular airbag 32 are fixedly connected to the outer end of the inflation tube a361. The end of the inflation tube b363 inserted into the outer tube 11 communicates with the interior of the airbag b37. Furthermore, at the end of the inflation tube a361 located outside the outer tube 11... Both the inflation tube b363 and the end of the inflation tube b363 located outside the outer tube 11 are fixedly connected to an inflation connector 364. The outer ends of the inflation tube a361 and the inflation tube b363 are fitted with tube clamps 365. The inflation connector 364 can be conveniently connected to an inflation device, such as an air cylinder. When it is necessary to inflate the airbag a31 or the annular airbag 32, the inflation device can be directly connected to the inflation connector 364 at the top of the inflation tube a361. The inflation device can then be used to inflate the annular airbag 32 and the airbag a31, causing them to expand.

[0038] Similarly, when it is necessary to inflate the airbag b37, the inflation device can be directly connected to the inflation connector 364 at the top of the inflation tube b363, allowing the inflation device to inflate the airbag b37 and make it expand. Furthermore, to prevent the air inside the inflated annular airbag 32 from leaking out through the inflation tube a361, the clamp 365 at its outer end can be squeezed after inflation to block the inflation tube a361 and prevent leakage.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
