Description

Tracheal catheter blocking device

Technical Field

The utility model relates to a endotracheal tube stifled pipe technical field especially relates to an endotracheal tube stifled ware suitable for metal endotracheal tube.

Background

A prior art metal endotracheal tube is shown in fig. 1. The metal tracheal catheters have different specifications, the inner diameters and the outer diameters of the metal tracheal catheters with various specifications are different, and the inner diameters of the metal tracheal catheters are usually 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm and the like.

The patient with the tracheal catheter needs to take out the tracheal catheter during rehabilitation. Before the tracheal catheter is taken out, whether the patient can breathe normally after the tracheal catheter is taken out needs to be tested, and the adopted method is to seal the tracheal catheter.

At present, few special pipe blocking devices are used clinically, and nurses can only block pipes by self-making plugs, for example, the size matched with the inner hole of the tracheal catheter is cut by wood, and then the tracheal catheter is plugged in to block the pipes. This approach is obviously cumbersome. If the corresponding plug is manufactured according to the inner diameter of the tracheal catheter for standby, many plugs with different specifications need to be stored, which is also inconvenient.

ZL201720321509.5 discloses a pipe blocking device of a tracheal cannula, in particular a tracheal catheter. The device is including being the echelonment body, and the diameter of body is from last to descending in proper order, thereby because the body has the endotracheal tube that multiple diameter can be used to multiple diameter. As shown in fig. 1, the endotracheal tube has only a small section which is straight and then curved, so that the length of the tube cannot be excessively long, otherwise the lowermost tube interferes with the curved portion of the endotracheal tube when the uppermost section of the tube is used. Every section of pipe body of the endotracheal tube blockage device can be stably inserted into the endotracheal tube only by a certain length, and the endotracheal tube blockage device is small in size of the adaptive endotracheal tube, or the endotracheal tube blockage device is not capable of being stably inserted into the endotracheal tube only due to the fact that every section of pipe body is short, and the endotracheal tube blockage device is easy to separate.

Zl201920200105.x discloses a tracheotomy tube blocking cap, which is also a tracheal catheter tube blocking device. The plugging cap has two tapered plugging caps so that endotracheal tubes of various diameters can be inserted. However, the tapered plug cap requires a large deformation of the plug cap by force to be inserted into the cylindrical endotracheal tube hole, which is inconvenient to insert and is easily removed after insertion.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: provides a tracheal catheter blocking device which is suitable for metal tracheal catheters of different specifications.

The technical scheme adopted for solving the problems is as follows: the endotracheal tube blocking device comprises a hexahedral tube blocking device main body, six surfaces of the tube blocking device main body are connected with plugs, and the diameters of the plugs are different.

Further, the method comprises the following steps: two vent grooves are symmetrically arranged on the plug, the sectional area of the vent grooves is gradually reduced from the top to the bottom of the plug, and a distance is reserved between the bottom of the vent grooves and the bottom of the plug.

Further, the method comprises the following steps: the pipe blocking device main body is provided with a diameter mark corresponding to the diameter of the plug.

Further, the method comprises the following steps: the pipe blocking device main body is of a hollow structure.

Further, the method comprises the following steps: the pipe blocking device main body is made of hard plastics, and the plug is made of rubber.

Further, the method comprises the following steps: the endotracheal tube blocking device comprises a connecting rope and a clamp, wherein the connecting rope is connected with the blocking device main body and the clamp.

The utility model has the advantages that: 1. the utility model discloses have the end cap that six diameters are different, consequently the endotracheal tube of adaptable six specifications makes things convenient for the hospital to carry out the trachea stifled pipe.

2. Each plug can have a proper length and is cylindrical, can be well matched with the hole of the tracheal catheter, and is not easy to fall off; the length of the plug is not too long, and the plug cannot interfere with the bending section of the tracheal catheter.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 2 to 5, the endotracheal tube blocking device comprises a hexahedral tube blocking device body 1, wherein plugs 2 are connected to six faces of the tube blocking device body 1, and the diameters of the plugs 2 are different.

When the tube is blocked, as shown in fig. 6, a plug 2 matched with the inner diameter of the tracheal catheter 5 is selected to be inserted into the tracheal catheter 3, so that the tube can be blocked. A tracheal catheter blocking device is provided with six plugs 2 with different diameters, so that the tracheal catheter blocking device can adapt to tracheal catheters 3 with six specifications. The two different endotracheal tube blocking devices are provided with twelve blocking heads 2 with different diameters, and can basically adapt to the existing endotracheal tubes 3 with all specifications.

The first endotracheal tube blocking device shown in fig. 2 and 3 can only directly and completely block the tube. When the tracheal catheter is blocked, a small part of ventilation area is blocked, then the blocking area is gradually increased until the blockage is completed, and the tolerance of a patient is tested step by step. Therefore, the utility model discloses can further map 4 and the improvement of fig. 5, the symmetry is provided with two air channel 21 on second kind endotracheal tube's end cap 2 promptly, and air channel 21 reduces from end cap 2 top to bottom sectional area gradually, has the distance between air channel 21 bottom and end cap 2 bottom.

The plug 2 of the second endotracheal tube should be longer than the plug 2 of the first endotracheal tube. When the tracheal catheter is used, the plug 2 is partially inserted into the tracheal catheter 3, the vent groove 21 is not completely covered by the tracheal catheter 3, and the vent groove 21 can be used for ventilation, so that partial blockage of the catheter is realized. The insertion depth of the plug 2 is gradually increased, and the area of the pipe plug is gradually increased because the sectional area of the vent groove 21 is gradually reduced from the top to the bottom of the plug 2. Finally, the plug 2 is completely inserted into the tracheal catheter 3 to completely plug the catheter.

In order to facilitate the medical staff to quickly select a proper plug 2, as shown in fig. 2 and 4, the pipe plugging device body 1 is provided with a diameter mark 11 corresponding to the diameter of the plug 2.

The stopper body 1 is preferably of hollow construction, so as to reduce the weight of the stopper 2. The occluder body 1 is preferably made of rigid plastic and the plug 2 is preferably made of rubber.

Although the utility model discloses relative background art the endotracheal tube blocking device of two patents is difficult more drops when using. However, for convenient insertion, the fitting between the plug 2 and the endotracheal tube 3 should not be too tight, and if the patient coughs, the airflow may flush out the endotracheal tube plug. In order to avoid falling after endotracheal tube blocking device breaks away from and contaminated or be difficult to look for, endotracheal tube blocking device is including connecting rope 3 and clip 4, connects rope 3 and is connected with blocking device main part 1 and clip 4. The clamp is clamped on the clothes of the patient, so that the tracheal catheter blocking device cannot fall to the ground even if being separated from the tracheal catheter 3.
