Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a silica gel nasopharyngeal ventilation tube. Background Art

[0002] The nasopharyngeal airway is a simple silicone ventilation device. It only needs to be correctly inserted into the nasal cavity to effectively solve the problem of nasal congestion, so that the patient can breathe smoothly. In order to avoid the nasopharyngeal airway entering the patient's nose, especially the nose of patients with larger nostrils, which will bring unnecessary trouble to the treatment process, the tube opening of the nasopharyngeal airway needs to be enlarged, that is, the diameter of the tube opening is increased. The traditional method of enlarging the hole is mainly to turn the hole. The so-called turning the hole is to turn the tube opening outward to increase the diameter of the tube opening. Although the operation is simple, the enlargement range is limited, and the safety improvement effect is not obvious. Based on this situation, how to enhance the enlargement effect of the tube opening of the nasopharyngeal airway, thereby enhancing the safety of the use of the nasopharyngeal airway, is becoming an increasingly urgent problem that relevant technical personnel need to solve.

[0018] In order to make the description clearer, a silicone nasopharyngeal ventilation tube of the utility model is further described in conjunction with the accompanying drawings of the specification.

[0019] A silicone nasopharyngeal ventilation tube includes a tube body 2, characterized in that: a base 1 is set at one end of the tube body 2, the base 1 and the tube body 2 are an integral structure, the base 1 is equal to the diameter of the tube body 2 at the end close to the tube body 2, and the base 1 is an annular cylinder with a diameter greater than the diameter of the tube body 2 at the end away from the tube body 2, and the diameter of the base 1 gradually increases from the end close to the tube body 2 to the end away from the tube body 2.

[0020] Furthermore, the cross-sectional shape of the edge of the base 1 is an arc shape.

[0021] Further, the design parameters of the tube body 2 include an outer diameter and an inner diameter. The design parameters of the tube body 2 and the base 1 as a whole are the overall length. The outer diameter of the tube body 2, the inner diameter of the tube body 2, and the overall length are set as the overall design parameters. The overall design parameters are fixed combinations, and the overall design parameters include the following combinations: 4.0, 3.0, 77, 4.7, 3.5, 90, 5.3, 4.0, 110, 6.0, 4.5, 114, 6.7, 5.0, 120, 7.3, 5.5, 130, 8.0, 6.0, 135, 8.6, 6.7, 145, 9.3, 7.0, 150, 10.0, 7.5, 160, 10.7, 8.0, 175, 11.2, 8.5, 185, 12.0, 9.0, 190, the unit of each parameter is mm, and the diameter of the annular column position of the base 1 is 30 mm.

[0022] Furthermore, the dimensional tolerances of the outer diameter and the inner diameter of the tube body 2 are both ±0.2 mm.

[0023] Furthermore, one end of the tube body 2 away from the base 1 is beveled, the bevel angle of the bevel is 45°, and the dimensional tolerance of the bevel angle is ±10°.

[0024] The working principle of the silicone nasopharyngeal ventilation tube of the utility model is as follows: after selecting the nasopharyngeal ventilation tube of the appropriate size according to the size of the patient's nostrils, slowly insert the end of the tube body 2 away from the base 1 into the patient's nasal cavity. The bevel design of this end allows the insertion process to proceed smoothly, and the insertion is continued until the outer wall of the base 1 fits the patient's skin. The large diameter of the annular column position of the base 1 keeps the nasopharyngeal ventilation tube stable and will not accidentally enter the patient's nasal cavity. The base 1 gradually increases in diameter and has an arc-shaped cross-section, so that the patient's skin at the contact position with the outer wall of the base 1 remains comfortable, and then the medical staff can proceed to the next medical action.

[0025] The above are only specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
