Description

Technical Field

[0001] The present application relates to a medical device, and in particular to an oxygen inhalation tube. Background Art

[0002] At present, the commonly used oxygen tubes in clinical practice are Figure 4 As shown, it mainly includes a main pipeline 10, a first end of the main pipeline 10 forms a ring pipeline 11 for being put on the patient's head, and two oxygen outlet nozzles are formed on the ring pipeline 11 for being inserted into the patient's nostrils; the second end of the main pipeline forms a trumpet-shaped plug connector for being put on the conical connector of the oxygen flow meter on the wall of the ward where the patient is located.

[0003] Since the oxygen tube is relatively long, in order to keep the bed unit tidy, the main line is usually coiled and bent and hung on the flow meter when the patient does not need oxygen. Since the oxygen tube is a plastic tube, it is easy to form a dead fold after coiling and bending. Once a dead fold is formed, the main line is partially concave and the cross-section becomes smaller, affecting the oxygen flow rate. The most likely place for a dead fold to form is the rear end of the bell-shaped plug connector. In addition, the bell-shaped plug connector and the tapered connector of the flow meter often loosen, causing oxygen leakage, and even the main line falls off from the tapered head. Utility Model Content

[0004] In view of the above problems, the present application aims to provide an oxygen tube, which is not easy to form a dead fold at the bell-shaped plug joint; the present application also aims to provide an oxygen tube, whose bell-shaped plug joint is not easy to loosen from the conical head of the flow meter; the present application also aims to provide an oxygen tube, which is not easy to form a dead fold on the main pipe.

[0005] The oxygen inhalation tube of the present application comprises a main pipe, a first end of which is formed with a ring-shaped pipe; a second end of which is formed with a bell-shaped plug connector, which is used to be inserted into the conical connector of the oxygen flow meter;

[0006] A first elastic component is installed on the outside of the bell-mouth-shaped plug connector of the main pipeline; the first elastic component includes a first solenoid spring, a fixing ring, and a plurality of claws; the first solenoid spring is sleeved on the outer periphery of the main pipeline near the bell-mouth-shaped plug connector; the fixing ring is fixed on the outer peripheral surface of the middle part of the first solenoid spring; the claws are made of elastic metal; the lower ends of the plurality of claws are fixed on the fixing ring; the upper ends of the plurality of claws extend toward the upstream of the bell-mouth-shaped plug connector; a clamping head protruding toward the axial direction of the bell-mouth-shaped plug connector is formed on the upper end of each clamping head; the clamping head is located upstream of the bell-mouth-shaped plug connector and is used to be clamped in the annular recessed portion of the conical connector of the oxygen flow meter.

[0007] Preferably, a second elastic member is disposed in the wall of the main passage; the second elastic member is formed as a second solenoid spring; the second solenoid spring is located between the inner wall and the outer wall of the main passage and surrounds the inner wall of the main passage.

[0008] Preferably, the second solenoid spring is distributed along the entire length of the main line.

[0009] Preferably, the number of the plurality of claws is 3; the 3 claws are evenly distributed along the circumference of the fixing ring.

[0010] The oxygen inhalation tube of the present application, through the first elastic component, can prevent the formation of dead folds at the bell-mouth-shaped plug connector on the one hand, and can be buckled into the annular recessed portion of the conical head of the oxygen flow meter through claws on the other hand, thereby increasing the connection stability between the bell-mouth-shaped plug connector and the conical head of the oxygen flow meter; in addition, the second elastic component arranged in the main pipeline can prevent the formation of dead folds at other positions of the main pipeline.

[0015] Below, the oxygen absorption tube of the present application is described in detail with reference to the accompanying drawings.

[0016] The oxygen inhalation tube of the present application comprises a main pipe 10, a first end of which is formed with a ring pipe 11; a second end of the main pipe 10 is formed with a bell-shaped plug connector 12 for inserting on a conical connector of an oxygen flow meter. These are the same as the oxygen inhalation tubes in the prior art.

[0017] The oxygen breathing tube of the present application is different in the following aspects.

[0018] A first elastic member 20 is mounted outside the bell-mouth-shaped plug connector 12 of the main pipe 10 .

[0019] The first elastic member 20 includes a first solenoid spring 22 , a fixing ring 21 , and a plurality of claws 23 .

[0020] The first solenoid spring 22 is sleeved on the outer periphery of the main pipe 10 near the bell-shaped plug connector 12; the fixing ring 21 is fixed on the outer periphery of the middle part of the first solenoid spring 22; the claws 23 are made of elastic metal, and the lower ends of the multiple claws 23 are fixed on the fixing ring 21; the upper ends of the multiple claws 23 extend toward the upstream of the bell-shaped plug connector 12; the upper end of each claw 23 is formed with a clamping head protruding toward the axial direction of the bell-shaped plug connector; the clamping head is located upstream of the bell-shaped plug connector 12, and is used to clamp in the annular recessed part of the conical connector of the oxygen flow meter, increase the bonding force between the bell-shaped plug connector 12 and the conical connector of the oxygen flow meter, and prevent the bell-shaped plug connector 12 from being disengaged from the conical connector of the oxygen flow meter as much as possible. The number of the multiple claws is 3; the 3 claws are evenly distributed along the circumference of the fixing ring.

[0021] A second elastic member 30 is disposed in the wall of the main passage 10; the second elastic member 30 is formed as a second solenoid spring; the second solenoid spring is located between the inner wall and the outer wall of the main passage 1- and surrounds the inner wall of the main passage. The second solenoid spring is distributed along the entire length of the main passage.

[0022] By disposing the first solenoid spring and the second solenoid spring, a dead bend is not easily formed at the corresponding position.

[0023] When in use, the operator holds the fixing ring of the first elastic member, and puts the first elastic member and the bell-shaped plug connector together on the conical connector of the oxygen flow meter, and the clamping head of the clamping claw is clamped in the concave part of the conical connector of the oxygen flow meter. At this time, the fixing ring pushes the bell-shaped plug connector toward the conical connector of the oxygen flow meter, so that the bell-shaped plug connector is tightly attached to the conical connector of the oxygen flow meter; because the first solenoid spring and the second solenoid spring provide strength to resist bending when the corresponding positions of the main pipe are bent, and provide elastic force to restore the original state, it is not easy to form a dead bend on the main pipe.
