[0001] This utility model relates to the field of medical device technology, specifically a dual-guidewire multifunctional transnasal tube. Background Technology

[0002] Nasoenteric tube feeding is a safe and effective method of enteral nutrition therapy. Nasoenteric tube feeding involves inserting a tube through the nasal cavity, through the pharynx, esophagus, and stomach, into the duodenum or jejunum for the delivery of enteral nutrition.

[0003] Some patients require both a gastric tube and a nasoenteric tube during treatment. The gastric tube is used to relieve abdominal distension and the nasoenteric tube is used to administer enteral nutrition. Having two tubes inserted into the patient's nasal cavity at the same time inevitably increases the patient's suffering. Utility Model Content

[0004] The purpose of this invention is to provide a dual-guidewire multifunctional transnasoenteric tube to solve the problem mentioned in the background art where some patients need to have both a gastric tube and a nasoenteric tube inserted at the same time during treatment. The gastric tube is used for abdominal distension and decompression, while the nasoenteric tube is used for enteral nutrition. The patient has two tubes inserted into their nasal cavity at the same time, which inevitably increases the patient's pain.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-guidewire multifunctional transnasoenteric tube includes a catheter with decompression cavities and nasoenteric cavities on both sides, a feeding cavity in the middle, and a connector at the top. Several sets of equidistant side holes are formed on the lower surface of one side of the catheter, the inner cavities of which communicate with the inner cavities of the feeding cavities. Equidistant pressure relief holes are formed on the upper middle surface of one side of the catheter. A connecting tube is inserted into the surface of the connector, one end of which communicates with the inner cavity of the nasoenteric cavity. An extension tube is connected to the surface of the connector, one end of which communicates with the decompression cavity, and the other end of which is connected to a decompression connector.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a dual-guidewire multifunctional transnasoenteric tube, including a catheter 100. A decompression chamber 107 and a nasoenteric cavity 109 are respectively opened on both sides of the catheter 100. A feeding cavity 108 is opened in the middle of the catheter 100. A connector 103 is connected to the top of the catheter 100. Several sets of equidistantly arranged side holes 101 are opened on the lower surface of one side of the catheter 100, and the inner lumens of the side holes 101 are connected to the inner lumens of the feeding cavity 108. Equidistantly arranged pressure relief holes 102 are opened on the upper surface of one side of the catheter 100, and the pressure relief holes 102 are connected to the decompression chamber 107. When the catheter 100 is inserted into the human body, the pressure relief holes 102 are located in the stomach. A connecting tube 106 is inserted into the surface of the connector 103, and one end of the connecting tube 106... The tube 106 is connected to the inner lumen of the nasoenteric cavity 109. The other end of the connecting tube 106 is connected to the nasoenteric cavity connector 116. The nasoenteric cavity 109 opens at the tip of the catheter 100. The surface of the connector 103 is connected to the extension tube 104. One end of the extension tube 104 is connected to the decompression chamber 107, and the other end of the extension tube 104 is connected to the decompression connector 113. Through the setting of the decompression chamber 107 and the feeding chamber 108, the decompression chamber 107 can aspirate the gas and liquid accumulated in the stomach. The feeding chamber 108 is used for enteral nutrition infusion, which solves the problem of providing enteral nutrition support through jejunal feeding. When the patient has two treatment needs at the same time, the clinical needs can be met simultaneously, avoiding the patient having two tubes, namely a gastric tube and a nasoenteric tube, at the same time, thereby reducing unnecessary pain for the patient.

[0022] Furthermore, a second guidewire 110 is inserted into the lumen of the nasoenteric cavity 109. One end of the second guidewire 110 is fixedly connected to a temperature-sensitive metal wire 112. The length of the second guidewire 110 is more than twice that of the nasoenteric cavity 109. The surface of the second guidewire 110 is provided with graduation lines 111. With the setting of the second guidewire 110, the catheter 100 can be replaced in a very short time, reducing the pain caused to the patient by re-inserting the catheter 100 and facilitating clinical operation. Moreover, when the second guidewire 110 passes through the front part of the nasoenteric cavity 109 during use, the temperature-sensitive metal wire 112 connected to one end of the second guidewire 110 is affected by the temperature and automatically bends into a U-shape, which will not cause damage to the intestinal mucosa, making it safe and convenient to use.

[0023] Furthermore, the catheter 100 has a hydrophilic layer 115 on its wall, and the catheter 100 is made of polyurethane material. Through the setting of the hydrophilic layer 115, the catheter 100 wall has a hydrophilic layer 115, which is mainly made of one or more of polyvinylpyrrolidone, hyaluronic acid, polyethylene glycol, chitosan, etc. The hydrophilic layer 115 makes the catheter insertion process smoother and more convenient to operate, suitable for clinical use, and meets the needs of a wide range of clinicians.

[0024] It is worth noting that a first guidewire 105 is inserted into the feeding cavity 108. The first guidewire 105 provides support for the feeding cavity 108, facilitating the placement of the nasoenteric tube.

[0025] A connecting tube is inserted into the surface of the connector 103. One end of the connecting tube 118 is connected to the inner cavity of the feeding chamber 108, and the other end of the connecting tube 118 is connected to the feeding connector 117. Medical staff can inject the prepared nutrient solution into the feeding chamber 108 through the feeding connector 117.

[0026] Preferably, the surface of the catheter 100 is provided with scale markings 114 to facilitate medical staff in understanding the length of the catheter 100 inserted into the patient's body.

[0027] Working principle;

[0028] The catheter 100 is inserted through the nasal cavity, through the pharynx, esophagus, and stomach, and into the duodenum or jejunum. Nutrient solution is injected into the feeding cavity 108 and flows out through the side holes 101, which are spaced 1 cm apart. Multiple side holes are provided to reduce the risk of obstruction of the feeding cavity 108. The pressure relief hole 102 is located in the patient's stomach to relieve abdominal distension and can also be used to administer medications injected into the stomach. The decompression cavity 107 acts as a gastric tube. When the feeding cavity 108 is blocked, the second guidewire 110 is inserted into the nasoenteric cavity 109, extending beyond the tip of the catheter 100. The second guidewire 110 is held in place, and the catheter 100 is pulled out along the second guidewire 110. The second guidewire 110 is then inserted into another catheter 100, and the catheter 100 is reinserted into its original position along the second guidewire 110. Furthermore, a temperature-sensitive metal wire 112 is fixedly connected to one end of the second guidewire 110. When the second guidewire 110 is used to replace the nasoenteric cavity 109, the guidewire is in a straight state due to the limitation of the lumen. When the guidewire passes through the front end of the nasoenteric cavity 109, the temperature-sensitive metal wire 112 automatically bends into a U-shape due to the temperature effect, which will not damage the intestinal mucosa.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
