Description

Technical Field

[0001] This utility model relates to the field of therapeutic tube feeding, and in particular to a nasoenteric tube assembly for preventing unplanned extubation. Background Technology

[0002] A nasoenteric tube is a medical device used in clinical medicine, particularly in the treatment of gastrointestinal diseases and nutritional support for critically ill patients. It is inserted through the nasal cavity, passes through the esophagus and stomach, and finally reaches the duodenum or upper jejunum to deliver nutritional fluids or medications, helping patients maintain their nutritional status or treat related diseases.

[0003] Patent document CN202211000602.8 discloses a nasoenteric tube placement method, which inserts and places the nasoenteric tube using a traction device. Traditional nasoenteric tube designs are relatively simple, mainly consisting of a long, thin tube with an open end for fluid delivery. However, this design has several drawbacks. First, due to the lack of effective guidance and positioning devices, insertion is difficult, easily causing damage to the patient's nasal cavity and gastrointestinal tract, increasing patient discomfort. Second, the lack of a fixation device during use makes unplanned removal of the tube common, leading to treatment interruption and potentially serious complications. Furthermore, the soft material of the nasoenteric tube makes it prone to kinking or blockage within the body, affecting fluid delivery. Utility Model Content

[0042] Liquid food can be fed into the patient's intestines through tube 1 and outlet 11;

[0043] The limiting bladder structure 2 includes a water injection channel 21 and a water bladder 22. The water bladder 22 is fixedly installed on the outer periphery of the tube body 1. The two ends of the water injection channel 21 are respectively connected to the water bladder 22 and the second connector. Water is injected into the water injection channel 21 and the water bladder 22 through the second connector.

[0044] Water inlet channel 21 is connected to pipe body 1 in a parallel arrangement;

[0045] Water inlet channel 21 can be embedded in pipe body 1 for integrated design;

[0046] The water bladder 22 is disposed between the input end of the tube body 1 and the output hole 11, and the water bladder 22 is disposed close to the output hole 11;

[0047] A guide wire 7 is inserted into the tube body 1. The guide wire 7 is made of a metal material that can be bent and deformed. The guide wire 7 is mainly used to insert into the flexible tube body 1, thereby providing a certain guiding force and support force to the tube body 1 and preventing the tube body 1 from swinging at will. The guide wire 7 is a commonly used device in the field of internal tubes. The specific structure and principle will not be described here.

[0048] Multiple output ports 11 are arranged in a row;

[0049] The diameter of output hole 11 is set to 0.5-1.5cm;

[0050] The counterweight 5 is provided with grooves 51, and multiple grooves 51 are provided and arranged in a mutually arranged manner;

[0051] The tube body 1 is also provided with an output hole 11 corresponding to the position of the groove 51;

[0052] The groove 51 allows liquid food to be discharged from the outlet hole 11 at the groove 51 position into the tube 1, preventing food from accumulating at the end of the tube 1.

[0053] Counterweight 5 is made of titanium, alloy or ceramic materials;

[0054] In some specific embodiments of this utility model, reference is made to Figure 3 , Figure 4 The fixator 3 includes a nose pad 31, an elastic limiting clip 32 and a support wing plate 33. Two support wing plates 33 are provided and symmetrically arranged on the outer sides of the two nostrils of the nose pad 31. The elastic limiting clip 32 is arranged on the nostril side of the nose pad 31.

[0055] Furthermore, the elastic limiting clamp 32 is made of elastic material. During installation, the sleeve 6 of the pipe body 1 is inserted into the limiting clamp for limiting and fixing.

[0056] In some specific embodiments of this utility model, reference is made to Figure 6 As shown, the binding mechanism 4 includes a connecting rope 41 and an elastic band 42. The support wing plate 33 of the fastener 3 is provided with a rope hole. One end of the connecting rope 41 is connected to the rope hole, and the other end is connected to the elastic band 42. There are two sets of connecting ropes 41. The two ends of the elastic band 42 are respectively connected to the two connecting ropes 41.

[0057] Furthermore, the elastic band 42 is configured as a hook and loop fastener structure, comprising a male and female hook and loop that are glued together, and the male and female hook and loop are respectively connected to different connecting ropes;

[0058] Specifically, the connecting rope and the elastic band are connected by sewing;

[0059] In some specific embodiments of this utility model, the first connector and the second connector are commonly used connectors for connecting catheters and syringes. Their specific function is to facilitate the connection between the syringe and the tube body 1 and the water injection channel 21, and at the same time, they are in a closed state when not in use, thereby keeping the tube body 1 and the water injection channel 21 isolated from the external environment.

[0060] In practical use, measure the required length of tube 1, cut off the excess part from the first end, and then insert the end with the counterweight 5 into the patient's nasal cavity through the nostril. Guided by the guide wire 7, it passes through the stomach and enters the pylorus, allowing the water balloon 22 to enter the pylorus as well. Then, stop the insertion, install the tube sleeve 6 onto tube 1, and then install the first connector on the first end of tube 1. After inserting the tube sleeve 6 into the limiting clamp of the fixator 3, the fixator 3 is bound to the user. Then, water can be injected into the second connector to inflate the water balloon 22, which is then fixed below the pylorus.

[0061] Specifically, this utility model, by setting a counterweight 5, enables the nasoenteric tube to pass more smoothly through the nasal cavity and gastrointestinal tract during insertion, reducing damage to the patient and ensuring the smooth insertion and positioning of the tube body 1.

[0062] Meanwhile, the counterweight 5 is provided with a groove 51 and a corresponding output hole 11 to prevent liquid food from accumulating at the position of the counterweight 5.

[0063] The tube body 1 is designed as an integrated semi-enclosed structure to prevent the counterweight 5 from detaching from the tube body and falling into the human body;

[0064] By setting up a limiting sac structure 2 and injecting water into the water sac 22 through the water injection channel 21, the water sac 22 expands, thereby fixing it below the pylorus and preventing the nasoenteric tube from shifting inside the body. The binding mechanism 4 binds the fixator 3 to the patient's head through the connecting rope 41 and the elastic band 42, further enhancing the fixation effect of the nasoenteric tube. The synergistic effect of these structures effectively solves the problem of unplanned extubation that is common with traditional nasoenteric tubes, improving the safety and reliability of the treatment.

[0065] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
