BRIEF DESCRIPTION OF THE FIGURES

[0029] To better understand what has been set forth above, several drawings schematically depicting a practical embodiment only by way of non-limiting example are attached.

[0030] FIG. 1 shows a perspective view of the medical device for the insertion of a tube object of the invention.

[0031] FIG. 2 shows a cross-sectional view of the medical device in the use position in a patient, when the tube is inserted through the mouth.

[0032] FIG. 3 shows a cross-sectional view of the medical device in the use position in a patient, when the tube is inserted through the nose.

DETAILED DESCRIPTION

[0033] As seen in FIGS. 1, 2 and 3, of a preferred embodiment of the invention, the medical device enables the introduction of a tube 5 from an oral or nasal cavity to the oesophagus 62 of a patient 6, and comprises tubing 1 and an inlet body 2, wherein the inlet body 2 has a conical shape and is joined to the tubing 1 at a point in the lower half of the referred-to vertical dimension of the tubing 1; both elements further being in connection through a through hole 3 which communicates them internally.

[0034] Specifically, FIG. 1 shows that along the entire vertical axis of the device, both in the tubing 1 and the inlet body 2, there is a slotted channel 4 through which the withdrawal of the assembly from the body of the patient is facilitated. Another noticeable detail in FIG. 1 is that the tubing 1 has a bending point 11 located in the vertical dimension thereof above the inlet body 2, which enables the tubing 1 to be bent or flexed, thus facilitating the location thereof when it is introduced by a specialist orally into a patient.

[0035] Moreover, both FIG. 2 and FIG. 3 show the device located in the body of a patient 6 between the posterior pharynx 61 and the upper third of the oesophagus 62. For this reason, both figures show how the device occupies the anatomical vacuum in the body of the patient, being capable of adapting to the anatomy of said region.

[0036] Thus, FIG. 2 shows in detail the device and the position occupied by a tube which has been introduced into a patient through the mouth to the oesophagus 62 through the device. In this case, as shown in this figure, the tube 5 is inserted into the device along the entire tubular cross section of the tubing 1, since the introduction of this tube 5 has been through the upper end of the tubing 1 or end of the tubing 1 protruding from the oral cavity of the patient 6. Therefore, in this figure it can be seen how by means of the device, the patient 6 is protected internally, from the posterior pharynx 61 to the oesophagus 62, from the possible damage that a tube 5 can produce when it is introduced from the oral cavity.

[0037] Moreover, FIG. 3 shows the representation of the device located in the body of a patient 6, and wherein it shows the position of a tube 5 through the device of the invention, which is introduced from the nose of the patient 6. In this representation, it is observed that the tube 5 is inserted into the device through the inlet body 2 of the device, which is communicated with the tubing 1 by means of a common through hole 3, such that when the tube 5 is introduced through the nasal cavities of the patient 6, this tube 5 is inserted into the device through the inlet body 2 to the end of tubing 1, which is housed in the oesophagus of the patient 62 or the lower end of the tubing 1. For this reason, in this figure it is seen how by means of the device, the patient 6 is protected internally, from the posterior pharynx 61 to the oesophagus 62, from the possible damage produced by a tube 5 when it is introduced from the nasal cavity.

[0038] Next, the operation of device 1 is described.

[0039] The device is introduced into the patient 6 through the oral cavity, sliding it over the surface of the hard palate, and once it has gone beyond the inlet body 2, it is deployed in the oropharynx, specifically between the posterior pharynx 61 and the upper third of the oesophagus 62. Once the device is in this position, the tube 5 can be introduced through the upper end of the tubing 1 or through the nasal cavity.

[0040] When introducing the tube 5 through the upper end of the tubing 1, the specialist moves it through the inside of the tubing until it reaches the lower end, where it comes out and is housed in the oesophagus 62. Before introducing it into the device, the tube 5 can be lubricated to facilitate the insertion thereof and movement through the tubing 1.

[0041] When the tube 5 is introduced through the nasal cavity, it runs through said cavity until it reaches the posterior portion of the pharynx where it is received by the inlet body 2. Once inside, the conical shape of the inlet body 2 guides the tube 5 to the through hole 3 in order to introduce it into the tubing 1. Once the tube 5 is introduced into the tubing 1, it continues the movement thereof until it reaches the lower end, through which it comes out and is housed in the oesophagus 62.

[0042] The device can be removed from inside the patient 6 without the tube 5 positioned in the oesophagus 62 needing to be removed. To do so, the device elastically deforms so that the slotted channel 4 enables the tube 5 to pass through it.
