Description

Catheter for inserting a gastrointestinal tract {Catheter for inserting into a gastric}

The present invention relates to a catheter for insertion of the gastrointestinal tract, and more particularly, it can be easily inserted into the gastrointestinal tract along the esophagus through the oral cavity or nasal cavity, and selectively expands the diameter of the catheter directly below the body, which is the boundary region of the esophagus and stomach. The present invention relates to a catheter for inserting a gastrointestinal tract, which can prevent the catheter from easily falling out in the reverse direction and also efficiently maintain the insertion state of the catheter.

In general, there are a variety of situations in which the catheter needs to be inserted into the body for the treatment of a patient, especially when it is necessary to place an artificial airway, such as an endotracheal tube, into the body's respiratory system, or Such catheters are used when it is necessary to administer a drug into the gastrointestinal tract, or to remove or acquire the contents of the gastrointestinal tract.

For example, the main function of artificial airways during surgical operations is to keep the patient's airways open so that adequate lung gas exchange can be maintained during the surgical procedure. Alternatively, for many patients it is important that airway secretions are removed regularly if the tracheal tube is in place to maintain mechanical respiration for long periods of time. This can generally be achieved by using an inhalation catheter for respiration, and after insertion of the inhalation catheter, negative pressure is applied to the inside of the catheter to allow the discharge of sputum or other secretions from the respiratory system to the outside.

The catheter inserted into the gastrointestinal tract is used to remove gas and secretion in the gastrointestinal tract, extract gastric contents necessary for the examination, directly administer food and drugs into the gastrointestinal tract, and to wash the stomach when bleeding the upper gastrointestinal tract. It is then inserted into the gastrointestinal tract through the esophagus and branch.

However, such a catheter can be easily inserted into the gastrointestinal tract along the esophagus through the oral cavity or nasal cavity, but it is frequently detached, so that the catheter can not be efficiently inserted. Since the catheter must be inserted, there are disadvantages that cause a lot of inconvenience to the patients. In addition, since the insertion of the catheter should be performed while the therapists are artificially maintained, there is a problem in that efficiency or competitiveness is deteriorated because additional labor is required for the intern, resident doctor or other therapists.

The catheter for insertion of the gastrointestinal tract of the present invention includes a first open portion 14 for discharging (or inflow of gastric contents) from the tubular body 11 at one end of the tubular body 11 and the other end. The part is provided with a second open portion 13a for the inflow (or outflow of gastric contents) into the tubular body 11, and the second open portion 13a is provided with a removable stopper 30.

A fluid inlet tube 12 is further provided for introducing a fluid such as gas through a fluid inlet 12a branched from the tubular body 11 near the second open portion, and the fluid inlet tube 12 is a tubular body. Located in (11), it is made so that the bulge (balloon) 20 is located at the junction of the esophagus and stomach, and the length from the balloon to the end of the tip (tip) of the tubular body (11) is long. In the present invention, the length from the balloon to the tip of the tip (tip) of the tubular body 11 may be made to be about 20 cm.

That is, as shown in Figures 1 to 4, the catheter 10 according to the present invention is integrally along the longitudinal direction so that the fluid injection tube 12 and the first passage 13 in the interior of the body each have a space independent of each other The tubular body 11 is formed, and the rear end of the tubular body 11 has a fluid inlet 12a that is delivered from the fluid injection tube 12 and a second open portion that is extended from the first flow passage 13 ( 13a) are branched from each end, respectively, and a stopper 30 capable of opening and closing the second open portion is detachably attached to the second open portion 13a, and a radial direction is provided on the outer peripheral side of the tip side of the tubular body 11. Inflated portion 20 is formed integrally to enable a volume expansion. In this case, the fluid inlet 12a may be made of a material in which the inlet is automatically opened by elasticity when the nozzle for air injection is inserted, and the inlet is forcibly closed by the restoring force when the external nozzle is separated.

The tubular body 11 is a first flow path for the flow of the liquid or gas flows in and out through the front and rear ends, respectively, the front end and the rear end of the body is opened as shown in Figs. (13) is formed in the longitudinal direction inside the body. The tip end of the tubular body 11 is formed in a closed state in a closed shape, and the first open part 14 for outflow and inflow of the fluid is opened on the side of the tip end side of the tubular body 11. In addition, the tubular body 11 has a connecting passage 15 connecting the inner space of the inflating part 20 and the inner space of the fluid injection tube 12 to the side of the portion where the inflating part 20 is located. 4 and 5c and 5d are formed so that the fluid supplied through the fluid injection tube 12 can be supplied into the inflation portion 20.

The fluid injection tube 12 is provided in the tubular body 11 to supply the fluid necessary for adjusting the internal pressure of the bulging portion 20 through the inside of the tubular body 11 as shown in FIGS. 5A to 5D. It is integrally formed along the longitudinal direction, and the fluid inlet tube 12 supplies the fluid (for example, air) necessary for adjusting the internal pressure of the inflating part 20 to the air inlet 12a of the rear end of the tubular body 11. It is formed from the rear end of the tubular body 11 to the swelling portion 20 so as to be supplied through.

The inflated portion 20 is integrally formed in a form surrounding the outer circumferential surface of the tubular body 11 as shown in FIGS. 5B to 5D, and when the volume is increased by the internal pressure, the diameter may be expanded in the radial direction. It is preferably made of an elastic member so that the internal space 21 in its expanded state is formed to be expandable in a spherical shape. This will prevent the tip of the tubular body 11 from being detached toward the upper esophagus by expanding the diameter of the swelling portion 20. In particular, the inflated portion 20 is formed at a position spaced a predetermined distance from the tip of the tubular body 11, as shown in Figures 3 and 4, the inflated portion 20 is the body (pyloric) between the esophagus and the stomach It is preferable to be formed about 10 cm away from the tip of the tubular body 11 by the distance from the bottom (frontal vestibule) to the powder in the stomach to be located directly below.

Figure 6 is a reference diagram illustrating a state in which the bulging portion is expanded immediately below the powder in the state in which the catheter is inserted into the gastrointestinal tract, the operation of the gastrointestinal insertion catheter of the present invention configured as described above and the effects thereof Explain.

First, the catheter 10 according to the present invention is inserted into the bottom of the gastrointestinal tract through the esophagus by inserting the distal portion 20 into the oral cavity or the nasal cavity while the inflated portion 20 is not expanded as shown in FIGS. 1 and 3. Then, when a fluid such as air is injected into the fluid injection tube 12 through the fluid injection port 12a at the rear end of the catheter, the fluid injected along the fluid injection tube 12 is inflated 20 and the fluid injection tube 12. Through the connecting passage (15) formed between the can be introduced to the inside of the inflated portion (20). Accordingly, as the volume of the fluid flowing into the swelling portion 20 increases, its internal pressure gradually increases, and the swelling portion 20 made of an elastic member increases its surface due to the increase of the internal pressure thereof. As shown in FIGS. 2 and 4, the diameter extends radially from the outer circumferential surface of the tubular body 11, and a spherical inflated portion 20 can be formed. Therefore, when using the catheter according to the present invention, it is possible to expand the inflated portion 20 of the catheter 10 in a state located directly below the body between the esophagus and the stomach as illustrated in FIG. 6.

When using a catheter inserted into the gastrointestinal tract in this state, the catheter does not have to be removed from the gastrointestinal tract, so that gas and secretion of the gastrointestinal tract is removed, gastric contents required for examination, or food and drugs are directly administered into the gastrointestinal tract. In the event of bleeding from the upper gastrointestinal tract, gastric lavage or the like can be safely performed. The treatment operation such as extraction or administration can be made through the first passage 13 formed inside the tubular body 11 in a state where the stopper 30 is opened and the second open portion 13a is opened. Since the tip end of the tubular body 11 is formed in a closed state in a round shape, and the first open part 14 for the inflow and outflow of fluid is formed at the front end side of the tubular body 11, the end of the tubular body is formed in the gastrointestinal tract. Even when placed in contact with the bottom, the bottom of the gastrointestinal tract does not block the first open portion 14 of the tubular body.

Then, when the catheter is to be removed after being inserted into the oral cavity or the nasal cavity, the fluid injected into the swelling portion 20 is opened through the fluid inlet 12a that is addressed to the end of the fluid inlet tube 12. ) And fluid inlet tube (12) By discharging in the opposite direction as in the injection, the diameter of the swelling portion 20 can be reduced to its original state, and thus can easily detach the catheter inserted into the gastrointestinal tract through the esophagus and the powder.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible. Accordingly, it is intended that the scope of the invention be defined by the claims appended hereto, and that all equivalent or equivalent variations thereof fall within the scope of the present invention.
