Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of drainage tube, in particular to a double-lumen tube for esophageal flushing, anti-aspiration and gastrointestinal decompression and drainage. BACKGROUND
[0002] In the prior art, for achalasia patients (whose pathophysiological characteristics are that the lower esophageal sphincter is not relaxed, and a large amount of food residues are accumulated in the lower esophageal segment), if the preoperative esophageal preparation is not sufficient, esophageal mucosal edema and perforation are prone to occur during the operation, which not only leads to prolonged operation time of the patient, but also is prone to postoperative complications such as bleeding and infection. The preoperative use of physiological saline to repeatedly flush the lower esophageal segment has been used and recognized in clinical practice many times. The flushing removes food residues and clears the intraoperative endoscopic field, which is not only beneficial to the smooth operation, but also prevents aspiration risk during anesthesia induction and prevents postoperative complications. At present, for achalasia patients, a gastric tube is placed into the esophagus (30-35 cm) to perform repeated esophageal flushing, 4 to 6 times a day, to remove esophageal food residues. However, during the gastric tube flushing process, most patients cannot tolerate repeated flushing with the gastric tube placed in the esophagus and require extubation, which increases the frequency of repeated intubation, and the patients feel very uncomfortable during this process. In addition, part of the flushing liquid enters the stomach during flushing and cannot be drained in time. At the same time, the wall of the gastric tube used in the clinic does not have a specific scale to the esophagus, which needs to be measured externally, thereby increasing the clinical workload. In addition, the gastric tube is easily pulled out when inserted into the esophagus, and improper operation during esophageal flushing can also cause aspiration. SUMMARY

[0033] Example 1
[0034] As Figures 1 to 5As shown, the present application provides a double-lumen tube for esophageal flushing and aspiration prevention and gastrointestinal decompression and drainage, which comprises a first inner tube 1, and further comprises: a second outer tube 2 fixedly sleeved at the end of the first inner tube 1, the first inner tube 1 and the second outer tube 2 can fully clean the esophagus without repeated pulling, realize the double-lumen flushable esophagus, and effectively prevent the reflux of gastric lavage fluid and gastric contents, and prevent aspiration. The scale line range on the first inner tube 1 and the second outer tube 2 adopts 0cm to 100cm. The distance between one end of the second outer tube 2 and one end of the first inner tube 1 is 35cm. The first inner tube 1 and the second outer tube 2 adopt a medical silica gel tube with a length of 60cm to 100cm. The medical silica gel tube is a pipeline product commonly used in the medical field, mainly made of high-quality silicone rubber (silica gel) material. As a kind of biocompatible synthetic material, silica gel is widely used in medical devices. The application of silica gel tube in medicine is mainly because of its unique physical and chemical properties, such as high stability, softness, transparency and non-toxicity. A plurality of first flushing holes 11 are opened at one end of the first inner tube 1, a plurality of second flushing holes 21 are opened at one end of the second outer tube 2, and a gas bag 3 is sleeved at the middle part of the second outer tube 2. The gas bag 3 with a spherical structure can better adhere to the esophageal wall after being inflated with gastric lavage fluid, thereby better preventing the reflux of gastric lavage fluid and gastric contents and preventing suffocation. The first inner tube 1 and the second outer tube 2 are provided with corresponding scale lines 121. The scale line 121 refers to a line or scale on a measuring tool or instrument used to indicate the unit of measurement. When the first inner tube 1 and the second outer tube 2 are placed in the esophagus and stomach, the length of the first inner tube 1 and the second outer tube 2 placed in the esophagus and stomach can be known by checking the scale line 121 in real time, avoiding the trouble caused by advance measurement; the gas bag tube 4 and the esophageal flushing tube 6 corresponding to each other are arranged at the other end of the second outer tube 2. The gas bag tube 4 is a device that controls the position and fixation mode of the drainage tube by inflating or deflating according to the principle of gas bag. The esophageal flushing tube 6 mainly helps to clean the esophagus, remove accumulated secretions or food residues, or is used for drug or liquid infusion during treatment; the top tube 5 is fixedly connected to the other end of the first inner tube 1, and the two ends of the top tube 5 are fixedly connected with end heads 51. The end heads 51 can be clamped on the arc-shaped clamping sleeve 7 of the bite block mechanism, avoiding the arc-shaped clamping sleeve 7 from sliding out of one end of the top tube 5, and the bite block mechanism can only be taken out by elastic tension of the rubber elastic belt 8. The bite block mechanism is movably sleeved on the top tube 5.
[0035] Further, the bite block mechanism comprises a pair of arc-shaped clamping sleeves 7 clamping the top pipe 5, the outer wall of the arc-shaped clamping sleeve 7 is fixedly connected with a pair of support sleeve rods 73, the end of the support sleeve rod 73 away from the arc-shaped clamping sleeve 7 is slidably connected with a telescopic insertion rod 91, the outer wall of the arc-shaped clamping sleeve 7 is provided with a clamping tooth top rod 9 fixedly connected with the telescopic insertion rod 91, the middle portion of the outer wall of the clamping tooth top rod 9 is fixedly connected with a finger pressing plate 92 for pinching with fingers, the finger pressing plate 92 is manually pressed to drive the clamping tooth top rod 9 to move, so that the spacing between the clamping tooth top rods 9 becomes smaller, and finally the clamping tooth top rod 9 is put into the oral cavity of the patient of different sizes, and then the elastic pushing force of the reset spring 74 can make the clamping tooth top rod 9 suitable for different sizes of oral cavity. The spherical head 93 is arranged at both ends of the clamping tooth top rod 9 to avoid scratching the oral cavity, the reset spring 74 is fixedly connected in the inner portion of the support sleeve rod 73, and the end of the reset spring 74 away from the inner wall of the support sleeve rod 73 is fixedly connected with the end portion of the telescopic insertion rod 91.
[0036] The bite block mechanism further comprises a tooth bite block 71 fixedly connected to the arc-shaped clamping sleeve 7, and the tooth bite block 71 is fixedly connected with a protective pad 72 for biting teeth, the protective pad 72 is made of medical rubber material, which can not only protect teeth from clenching, but also can buffer and reduce shock. The middle portion of the arc-shaped clamping sleeve 7 is fixedly connected with a pair of rubber elastic bands 8, the rubber elastic band 8 is used to make the pair of bite block mechanisms suitable for pipes of different thicknesses, so that the bite block mechanism can be installed on pipes of different thicknesses. The pair of bite block mechanisms are symmetrically arranged with the rubber elastic band 8 as the center.
[0037] Secondly, the inner portion of the air bag pipe 4 is provided with a first lumen 41 in communication with the second flushing hole 21, the inner portion of the esophageal flushing pipe 6 is also provided with a second lumen 61 in communication with the second flushing hole 21, and the inner portion of the second outer pipe 2 is provided with an outer cavity 22 in communication with the second flushing hole 21, the first lumen 41 and the second lumen 61.
[0038] Further, the inner portion of the first inner pipe 1 is provided with an inner cavity 12 in communication with a plurality of first flushing holes 11, and the end of the first inner pipe 1 away from the top pipe 5 is provided with a drainage suction port 111 in communication with the first flushing hole 11 and the inner cavity 12.
[0039] In the embodiment, when the esophageal flushing anti-aspiration and gastrointestinal decompression drainage double-lumen tube needs to be used, as shown in FIG. 1, the first inner pipe 1 is connected with the second outer pipe 2, and the second outer pipe 2 is connected with the air bag pipe 4, and the air bag pipe 4 is connected with the esophageal flushing pipe 6. Figure 1As shown, the double-lumen balloon tube has a length of 60cm to 100cm medical silica gel tube inserted into the esophagus and stomach cavity from the oral cavity or nasal cavity of the human body, and the inner cavity 12 is connected with the negative pressure drainage device. In this way, the stomach is cleaned and the negative pressure drainage is achieved through the inner cavity 12, and the esophagus is flushed through the outer cavity 22. The double-lumen structure of the inner cavity 12 and the outer cavity 22 effectively realizes the flushing, negative pressure and drainage of the esophagus and stomach, effectively prevents the reflux of the flushing material during the flushing of the esophagus or stomach, and prevents suffocation. At the same time, it can also reduce the discomfort of the patient, facilitate the clinical operation and fixation, and facilitate the work of the clinical nurses. When the first inner tube 1 and the second outer tube 2 are inserted into the esophagus and stomach cavity, the end of the second outer tube 2 with the balloon tube 4 and the esophageal flushing tube 6 will approach the oral cavity. At this time, a pair of clamping tooth top rods 9 can be pulled in the opposite direction, and the rubber elastic band 8 connected with the end of the arc-shaped clamping sleeve 7 has elasticity, so that a pair of arc-shaped clamping sleeves 7 are moved to a segment of the second outer tube 2 placed in the oral cavity. Then, only the pair of clamping tooth top rods 9 need to be loosened, and the pair of arc-shaped clamping sleeves 7 can be fixed in the specified position through the elastic tension of the rubber elastic band 8. At this time, the patient can use the upper and lower teeth to bite the protective pad 72 on the corresponding tooth bite block 71, and the clamping tooth top rod 9 is clamped firmly on the upper and lower teeth through the elastic pushing force of the reset spring 74 at the end of the corresponding telescopic rod 91. When the pair of arc-shaped clamping sleeves 7 are firmly sleeved on the second outer tube 2 through the elastic tension of the rubber elastic band 8, the clamping tooth top rod 9 does not come out of the oral cavity, so that the first inner tube 1 and the second outer tube 2 cannot come out of the esophagus and stomach.
[0040] Example 2
[0041] The difference between this embodiment and example 1 is that the arc-shaped clamping sleeve 7 and the rubber elastic band 8 are removed, and the nose protection sleeve 10 is sleeved on the second outer tube 2 between the balloon 3 and the balloon tube 4, so as to reduce the pressure injury to the nasal mucosa during nasal insertion, so that the double-lumen drainage tube suitable for oral insertion is suitable for nasal insertion, and the use mode is changed.
[0042] The preferred embodiments of the above application are only used to help explain the application. The preferred embodiments do not describe all the details and limit the application to the specific embodiments. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and describes these embodiments in order to better explain the principles and practical applications of the application, so that those skilled in the art can well understand and utilize the application. The application is limited by the claims and their entire scope and equivalents.
