Abstract
The utility model relates to the field of medical instruments, in particular to a tracheal cannula with a rotatable connector.
Description
Technical Field
The utility model relates to the field of medical instruments, in particular to a tracheal cannula with a rotatable connector.
Background
At present, when a hospital establishes an artificial airway for a patient, a used tracheal cannula and a joint of a respiratory system are connected at the air inlet end of the tracheal cannula through one-time compression molding and cannot rotate at the air inlet end of the tracheal cannula, and the tracheal cannula inserted into a trachea can rotate when the body position of the patient changes or a pipeline at the end of the respirator rotates, so that tracheal secretions in the lung are increased, and the effect of establishing the artificial airway is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems and provides a tracheal cannula with a rotatable connector, which reduces the negative influence on a patient caused by rotation of the tracheal cannula.
In order to achieve the purpose, the utility model adopts the following technical scheme.
A rotatable-joint trachea cannula comprises a trachea cannula group (2), wherein a rotary joint group (1) is permanently installed at the air inlet end of the trachea cannula group (2), the rotary joint group (1) is composed of a rotary joint seat (11), a rotary joint (12), a clamp spring (13) and a sealing ring (14), the rotary joint seat (11) is permanently installed and connected with the air inlet end of the trachea cannula group (2), the rotary joint (12) is inserted into the rotary joint seat (11) to be matched and rotated, the clamp spring (13) is clamped in a clamp spring groove in a cylindrical surface where the rotary joint (12) and the rotary joint seat (11) are matched and rotated, and the sealing ring (14) is installed in a sealing ring groove of the rotary joint (12) and attached to an inner cylindrical surface of the rotary joint seat (11).
In the scheme, the clamp spring (13) is clamped in a clamp spring groove on a cylindrical surface where the rotary joint (12) and the rotary joint seat (11) are matched and rotated, so that the rotary joint (12) is prevented from axially moving and being separated, and the rotary joint (12) cannot be completely withdrawn after being inserted into the rotary joint seat (11) due to the radial elasticity of the clamp spring (13).
In the scheme, the sealing ring (14) is arranged in a sealing ring groove of the rotary joint (12) and is attached to the inner cylindrical surface of the rotary joint seat (11) to form sealing to low-pressure gas, and meanwhile, the rotary joint (12) is not prevented from rotating in the rotary joint seat (11) in a matching mode.
The rotatable trachea cannula with the connector has the advantages that:
(1) the trachea cannula can not rotate due to the connection of the breathing system pipeline when the body position of a patient changes;
(2) the utility model reduces the psychological pressure caused by the fear that the patient leans to the side to rotate the tracheal cannula when the patient enters deep sleep, and is beneficial to health recovery;
(3) the utility model has simple and reliable structure, and the possibility that parts fall off and fall into the air passage is avoided when in use;

fig. 2 is a partially enlarged schematic view of the rotary joint set of the present invention.
The reference numerals in the figures are respectively:
1. rotating the joint set; 2. a tracheal cannula set; 11. rotating the joint base; 12. a rotary joint; 13. a clamp spring; 14. and (5) sealing rings.
Detailed Description
The following detailed description of the rotatable endotracheal tube of the present invention is made with reference to the accompanying drawings.
Referring to fig. 1-2, in the joint rotatable tracheal cannula of the present invention, a rotary joint set 1 is permanently installed at an air inlet end of a tracheal cannula set 2, the rotary joint set 1 is composed of a rotary joint seat 11, a rotary joint 12, a clamp spring 13 and a seal ring 14, the rotary joint seat 11 is permanently installed and connected with the air inlet end of the tracheal cannula set 2, the rotary joint 12 is inserted and installed in the rotary joint seat 11 to rotate in a matching manner, the clamp spring 13 is clamped in a clamp spring groove on a cylindrical surface where the rotary joint 12 rotates in a matching manner with the rotary joint seat 11, and the seal ring 14 is installed in a seal ring groove of the rotary joint 12 to be attached to an inner cylindrical surface of the rotary joint seat 11.
Referring to fig. 1-2, the snap spring 13 is clamped in a snap spring groove on a cylindrical surface where the rotary joint 12 and the rotary joint seat 11 rotate in a matching manner, so that the rotary joint 12 is prevented from moving axially and being disengaged, and the rotary joint 12 cannot be completely disengaged after being inserted into the rotary joint seat 11 due to the radial elasticity of the snap spring 13.
Referring to fig. 1-2, the seal ring 14 is mounted in the seal ring groove of the rotary joint 12 and is fitted to the inner cylindrical surface of the rotary joint seat 11 to form a seal against low-pressure gas, while not interfering with the cooperative rotation of the rotary joint 12 in the rotary joint seat 11.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
Claims (3)
1. The rotatable-joint trachea cannula comprises a trachea cannula group (2) and is characterized in that the rotary joint group (1) is permanently installed at the air inlet end of the trachea cannula group (2), the rotary joint group (1) is composed of a rotary joint seat (11), a rotary joint (12), a clamp spring (13) and a sealing ring (14), the rotary joint seat (11) is permanently installed and connected with the air inlet end of the trachea cannula group (2), the rotary joint (12) is inserted into the rotary joint seat (11) to be matched and rotated, the clamp spring (13) is clamped in a clamp spring groove in a cylindrical surface where the rotary joint (12) and the rotary joint seat (11) are matched and rotated, and the sealing ring (14) is installed in a sealing ring groove of the rotary joint (12) and attached to an inner cylindrical surface of the rotary joint seat (11).
