Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a balloon guidewire gastric tube. Background Technology

[0002] In clinical practice, disposable gastric tubes are widely used for critically ill patients requiring gastrointestinal decompression and drainage or those dependent on enteral nutrition for life support due to impaired self-feeding ability. However, currently used gastric tubes have several shortcomings in practical application. On the one hand, gastric contents often reflux along the tube and subsequently invade the trachea. This situation, due to improper tube design, significantly increases the incidence of ventilator-associated pneumonia. On the other hand, there is a lack of ideal fixation methods after successful insertion. This makes the tube prone to complete or incomplete detachment, adversely affecting drainage and overall treatment outcomes. Currently, most gastric tubes are fixed to the nasal skin with adhesive tape after insertion. This fixation method not only affects aesthetics but also increases patient discomfort, especially for patients allergic to adhesive tape. Furthermore, the available tube diameters are limited, and the openings are small with few side holes, making tube blockage prone to occur during drainage. Meanwhile, some gastric tubes are made of overly soft materials, making successful insertion on the first attempt more difficult, especially for comatose or uncooperative patients. To address these issues, some researchers have improved existing gastric tubes. For example, the balloon guidewire gastric tube disclosed in Chinese utility model patent CN201375679Y solves some of the aforementioned problems to a certain extent. However, this balloon guidewire gastric tube presents the problem of inconvenience in replacement after a period of use, which still requires further optimization in practical clinical applications.

[0019] The usage of this utility model is as follows: This utility model has a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, firstly, the guidewire 6 is inserted into the gastric tube body 1, so that the cone clamp 4 is located in the clamping hole 5. Then, the fixing inflation device 9 is tightly connected to the left opening of the gastric tube body 1. The left side of the guidewire 6 is fixed in the cone hole 92 by the elastic clamp 93 and the locking screw 94, thereby ensuring the relative position stability of the guidewire 6 and the gastric tube body 1. Then, the gastric tube body 1 is inserted into the patient's body through the nasal cavity until the appropriate position is reached. Regarding the placement of the gastric tube, the guidewire 6 can be used to improve the accuracy of the insertion, especially for comatose or uncooperative patients. The guidewire 6 helps to complete the insertion procedure more smoothly. After the gastric tube 1 reaches the predetermined position, keep the position of the gastric tube 1 fixed, and then use the air pump 95 to inflate it. The gas passes through the valve chamber 99 (the ball 910 in the valve chamber 99 overcomes the elastic force of the spring 911 under gas pressure, allowing the gas to enter the trachea 7 through the porous cover 914) to inflate the cuff 2, causing the cuff 2 to expand, thereby placing the gastric tube 1 into the gastric tube. 1. Fixed inside the stomach to prevent displacement of the gastric tube 1. During inflation, the inflation pressure can be monitored using a pressure gauge 96 (digital pressure gauge) to avoid excessively high or low pressure affecting the fixation effect or causing harm to the patient. When gastrointestinal decompression is required, a negative pressure suction device can be connected through the left opening of the side tube 11. Stomach contents can be suctioned out through the through-holes 3 around the right side of the gastric tube 1. If enteral nutritional support is required, nutrients can be injected through the left opening of the side tube 11. The nutrients reach the stomach through the gastric tube 1 without causing... When in use, the left opening of the side tube 11 can be sealed with the cap 10 to prevent foreign objects from entering or liquid from leaking. When the gastric tube needs to be replaced, the gas in the air bladder 2 can be released through the vent screw 97 to make the air bladder 2 contract. Then, the locking screw 94 can be loosened to separate the elastic sleeve 93 from the guide wire 6. Then, the gastric tube body 1 and the fixed inflation device 9 can be slowly pulled out. At this time, the end of the guide wire 6 is located in the patient's stomach, which makes it easy to replace the new gastric tube body 1 along the guide wire 6, thus improving the convenience of use and preventing inaccurate positioning.
