Technical Field

[0001] The utility model belongs to the field of medical devices, and in particular relates to an improved nasopharyngeal airway. Background Art

[0002] The nasopharyngeal airway is an artificial airway inserted into the pharynx through the nasal cavity. It is used to be inserted into the pharynx through one side of the nasal cavity to displace the soft tissue of the pharynx to achieve the purpose of upper respiratory tract ventilation, and to relieve or alleviate the patient's upper respiratory tract ventilation or obstruction. The nasopharyngeal airway is generally made of soft silicone or plastic material. It is a slightly curved cylindrical tube, similar to an uncuffed endotracheal tube, but shorter, with a thinner and softer tube wall, moderate hardness, and its length increases with the increase of the inner diameter.

[0003] When the existing nasopharyngeal airway is disassembled and cleaned, the connection structure between the nasopharyngeal airway and the equipment is inconvenient for the staff to disassemble, thereby reducing the disassembly efficiency of the nasopharyngeal airway and failing to meet the staff's needs for the connection structure.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] See also Figure 1-5 As shown, in this embodiment, an improved nasopharyngeal airway is provided, comprising a fixing block 1, a device output tube 2 is provided on one side of the fixing block 1, a ventilation tube 3 is provided on the other side of the fixing block 1, and a fixing device is installed inside the fixing block 1;

[0029] The fixing device includes a U-shaped push rod 6, which slides in the interior of the fixed block 1. The interior of the fixed block 1 is slidably fitted with two pull rods 9. The surface of the pull rod 9 is equipped with a support block 13. The interior of the fixed block 1 is equipped with a limit block 15. The limit block 15 slides with the pull rod 9. A spring 2 14 is installed between the limit block 15 and the support block 13. The spring 2 14 is sleeved on the outside of the pull rod 9. Two placement grooves 7 are provided in the interior of the fixed block 1. An arc-shaped splint 5 is installed at one end of the pull rod 9 extending to the interior of the placement groove 7, and a fixing rod 10 is installed on one side of the arc-shaped splint 5.

[0030] The application of one aspect of this embodiment is as follows: when in use, first, the staff places the device output tube 2 inside the placement groove 7, and the staff pushes the device output tube 2 so that the device output tube 2 conflicts with the U-shaped push rod 6, thereby moving the U-shaped push rod 6. When the U-shaped push rod 6 moves out of the limiting groove 16, the limit on the pull rod 9 can be released. Under the action of the spring 2 14, the pull rod 9 moves the arc splint 5, and the movement of the arc splint 5 drives the fixed rod 10 to move. When the arc splint 5 contacts the device output tube 2, the fixed rod 10 passes through the adapter hole on the device output tube 2. It is clamped in the inside of the slot 11, and the fixing method of the vent pipe 3 and the fixed block 1 is the same as above. If the equipment output pipe 2 is to be disassembled, the staff pulls the pull rod 9. When the limit groove 16 on the pull rod 9 moves to correspond to the U-shaped push rod 6, the U-shaped push rod 6 can be clamped into the inside of the limit groove 16 under the action of the spring 12, so that the pull rod 9 can be limited. The movement of the pull rod 9 drives the arc-shaped splint 5 to move, and the movement of the arc-shaped splint 5 drives the fixing rod 10 to disengage from the inside of the slot 11, thereby releasing the fixation of the equipment output pipe 2. The disassembly method of the vent pipe 3 and the fixed block 1 is the same as above.

[0031] In this embodiment, the placement slot 7 is internally mounted with an arcuate fixing plate 4, which has a slot 11 defined on its surface. A fixing rod 10 engages with the slot 11. A pull rod 9, under the action of a spring 14, moves the arcuate clamping plate 5, which in turn moves the fixing rod 10. When the arcuate clamping plate 5 contacts the device output tube 2, the fixing rod 10 engages within the slot 11 through a matching hole in the device output tube 2.

[0032] The interior of the fixed block 1 of this embodiment is provided with two limiting blocks 2 17, and the limiting blocks 2 17 are slidably matched with the U-shaped push rod 6. By providing the limiting blocks 2 17, the limiting blocks 2 17 can be limited to maintain stability during operation.

[0033] In this embodiment, the fixed block 1 is provided with a venting groove 8, and the pull rod 9 is provided with a limiting groove 16. The U-shaped push rod 6 slides within the limiting groove 16. A fixing plate 18 is installed within the fixed block 1, and a spring 12 is installed between the fixing plate 18 and the U-shaped push rod 6. When a worker pulls the pull rod 9, when the limiting groove 16 on the pull rod 9 moves to correspond with the U-shaped push rod 6, the U-shaped push rod 6, under the action of the spring 12, can be engaged with the inside of the limiting groove 16, thereby limiting the position of the pull rod 9. The movement of the pull rod 9 drives the arcuate clamping plate 5 to move. The movement of the arcuate clamping plate 5 drives the fixing rod 10 to disengage from the inside of the clamping groove 11, thereby releasing the fixation of the device output pipe 2.

[0034] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
