DETAILED DESCRIPTION
[0033] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.
[0034] The embodiment of the present application discloses an adjustable disposable humidified oxygen inhalation tube. Referring to Figures 1 to 5, including a main pipe 1 and a set of branch pipes 2. One end of the main pipe 1 is used to communicate with the humidified oxygen source, and the other end of the main pipe 1 is provided with a shell 3; one end of the branch pipe 2 is used to insert into the patient's nostril, and the other end of the branch pipe 2 is provided with a ring seat 4. The ring seat 4 is sleeved on the shell 3, and the ring seat 4 is rotatably connected with the shell 3. A gas supply cavity 31 is formed in the shell 3, and the gas supply cavity 31 is in communication with the main pipe 1. A set of gas supply holes 32 are formed in the shell 3, and the gas supply holes 32 are in communication with the gas supply cavity 31. A gas guide cavity 41 is formed in the ring seat 4, and the gas guide cavity 41 is in communication with the branch pipe 2. A gas guide hole 42 is formed in the ring seat 4, and the gas guide hole 42 is in communication with the gas guide cavity 41. One of the gas guide holes 42 is used to be opposite to one of the gas supply holes 32, and the other gas guide hole 42 is used to be opposite to the other gas supply hole 32. A sealing gasket 5 is arranged between the ring seat 4 and the shell 3, the sealing gasket 5 is pasted on the inner ring wall of the ring seat 4, and the sealing gasket 5 is used to close the gas supply hole 32.
[0035] When the ring seat 4 is rotated, and the gas guide hole 42 on the ring seat 4 is opposite to the gas supply hole 32, the gas guide cavity 41 in the ring seat 4 is in communication with the gas supply cavity 31. When the humidified oxygen enters the gas supply cavity 31 along the main pipe 1, the oxygen in the gas supply cavity 31 enters the gas guide cavity 41 which is in communication with the gas supply cavity 31, and the oxygen in the gas guide cavity 41 flows to the patient along the branch pipe 2 which is in communication with the gas guide cavity 41. When the ring seat 4 is rotated, and the sealing gasket 5 on the ring seat 4 covers the gas supply hole 32, the gas guide cavity 41 in the ring seat 4 is cut off from the gas supply cavity 31. When the humidified oxygen enters the gas supply cavity 31 along the main pipe 1, the oxygen in the gas supply cavity 31 cannot enter the gas guide cavity 41 which is cut off from the gas supply cavity 31, and the gas guide cavity 41 which is cut off from the gas supply cavity 31 cannot supply oxygen to the patient. When the gas guide hole 42 on one of the ring seats 4 is opposite to one of the gas supply holes 32, and the gas guide hole 42 on the other ring seat 4 is opposite to the other gas supply hole 32, the two gas guide cavities 41 are in communication with the gas supply cavity 31, and the effect of the patient using two branch pipes 2 to inhale oxygen at the same time is realized. When the patient only uses one branch pipe 2 to inhale oxygen, by rotating the ring seat 4, the gas guide hole 42 on one of the ring seats 4 is opposite to one of the gas supply holes 32, and the sealing gasket 5 on the other ring seat 4 covers the other gas supply hole 32, so that only one gas guide cavity 41 is in communication with the gas supply cavity 31. The situation of oxygen escaping from the other branch pipe 2 is reduced, the oxygen is not wasted, and the cost of the patient inhaling oxygen is reduced.
[0036] In order to realize the dynamic sealing between the ring seat 4 and the shell 3, refer to Figures 1 to 5The upper sealing ring groove 511 is filled with sealing filler to form an upper packing layer 51, and the outer wall of the shell 3 and the inner wall of the upper sealing ring groove 511 are in close contact with the upper packing layer 51. The lower sealing ring groove 521 is formed on the side of the ring seat 4 facing the shell 3, and the lower sealing ring groove 521 is located below the air guide hole 42. The lower sealing ring groove 521 is filled with sealing filler to form a lower packing layer 52, and the outer wall of the shell 3 and the inner wall of the lower sealing ring groove 521 are in close contact with the lower packing layer 52. The upper packing layer 51 and the lower packing layer 52 realize dynamic sealing between the ring seat 4 and the shell 3, and reduce the escape of oxygen between the ring seat 4 and the shell 3.
[0037] Referring to Figures 1 to 5 A set of threaded inner sleeves 61 are sleeved on the shell 3, and the threaded inner sleeves 61 are integrally formed with the shell 3. A threaded outer sleeve 6 is sleeved on the threaded inner sleeve 61, and the threaded outer sleeve 6 is threadedly connected with the threaded inner sleeve 61. Connection sleeves 62 are rotatably arranged on opposite sides of the threaded outer sleeve 6, and the connection sleeves 62 are sleeved on the shell 3. Sliding blocks 7 are mounted on the side of the connection sleeves 62 facing the shell 3, and a plurality of sliding grooves 71 are formed in the outer wall of the shell 3. One of the sliding blocks 7 is slidingly arranged in one of the sliding grooves 71, and the other sliding block 7 is slidingly arranged in the other sliding groove 71. Insert rods 8 are integrally formed on opposite sides of the connection sleeves 62, and the ends of the insert rods 8 away from the connection sleeves 62 face away from the ring seat 4. Through holes and cut-off holes are formed in the back of the ring seat 4, and the insert rods 8 are inserted into the through holes and the cut-off holes. When the threaded outer sleeve 6 is rotated, the shell 3 and the connection sleeves 62 are relatively rotated with the threaded outer sleeve 6, and at the same time, the threaded outer sleeve 6 drives the connection sleeves 62 to move relative to the shell 3, so that the insert rods 8 on the connection sleeves 62 move relative to the ring seat 4. When the insert rods 8 are separated from the ring seat 4, the ring seat 4 is relatively rotatable with the shell 3. When the insert rods 8 are inserted into the through holes, the ring seat 4 and the shell 3 remain relatively stationary, and at this time the through cavity is in communication with the gas supply cavity 31. When the insert rods 8 are inserted into the cut-off holes, the ring seat 4 and the shell 3 remain relatively stationary, and the through cavity is cut off from the gas supply cavity 31.
[0038] Referring to Figures 1 to 5 The outer walls of the threaded outer sleeve 6 and the connection sleeves 62 are wrapped with rubber layers 9, and the rubber layers 9 increase the friction of the outer walls of the threaded outer sleeve 6 and the connection sleeves 62. A plurality of anti-slip ribs 91 made of rubber are integrally formed on the outer wall of the rubber layer 9, and the anti-slip ribs 91 increase the friction of the outer wall of the rubber layer 9.
[0039] The implementation principle of the adjustable disposable humidification oxygen inhalation tube is as follows: when the air guide holes 42 on the ring seats 4 are rotated to be oppositely arranged with the air supply holes 32, the air guide cavities 41 in the ring seats 4 are communicated with the air supply cavities 31; after the humidified oxygen enters the air supply cavities 31 along the main pipe 1, the oxygen in the air supply cavities 31 enters the air guide cavities 41 communicated with the air supply cavities 31, and the oxygen in the air guide cavities 41 flows to the patient along the branch pipes 2 communicated with the air guide cavities 41. When the sealing pads 5 on the ring seats 4 are rotated to cover the air supply holes 32, the air guide cavities 41 in the ring seats 4 are cut off from the air supply cavities 31; after the humidified oxygen enters the air supply cavities 31 along the main pipe 1, the oxygen in the air supply cavities 31 cannot enter the air guide cavities 41 cut off from the air supply cavities 31, and the air guide cavities 41 cut off from the air supply cavities 31 cannot supply oxygen to the patient. When the air guide holes 42 on one of the ring seats 4 are oppositely arranged with one of the air supply holes 32, and the air guide holes 42 on the other ring seat 4 are oppositely arranged with the other air supply hole 32, the two air guide cavities 41 are communicated with the air supply cavities 31, and the effect that the patient simultaneously uses two branch pipes 2 to inhale oxygen is realized. When the patient only uses one branch pipe 2 to inhale oxygen, the air guide holes 42 on one of the ring seats 4 are oppositely arranged with one of the air supply holes 32 by rotating the ring seats 4, and the sealing pads 5 on the other ring seat 4 cover the other air supply hole 32, so that the effect that only one air guide cavity 41 is communicated with the air supply cavities 31 is realized. The situation that the oxygen escapes from the other branch pipe 2 and is wasted is reduced, and the oxygen inhalation cost of the patient is reduced.
