[0030] As described in the background section, the production process of nasal oxygen cannulas requires inserting a three-way valve into the catheter. In existing technologies, this assembly is almost entirely done manually. This consumes a significant amount of time and labor, resulting in low production efficiency and increased manufacturing costs for nasal oxygen cannulas.

[0031] This utility model provides a nasal oxygen cannula alignment device, which can effectively clamp and align the cannula to facilitate the subsequent insertion of the three-way tube into the cannula, thereby improving the success rate and efficiency of cannulation.

[0032] See Figure 1 The nasal oxygen cannula alignment device of this utility model includes an alignment frame, an upper driver 150 and a lower driver 160, as well as an upper alignment clip 200 and a lower alignment clip 300. The alignment frame includes a base plate 110, a pair of side plates 120, an upper cylinder fixing plate 130, and a lower cylinder fixing plate 140. The pair of side plates 120 are installed on both sides of the base plate 110, and the upper cylinder fixing plate 130 and the lower cylinder fixing plate 140 are both installed between the pair of side plates 120.

[0033] The upper actuator 150 and the lower actuator 160 can be various types of driving devices, including but not limited to cylinders, electric cylinders, etc., preferably three-axis cylinders. The upper actuator 150 is mounted on the upper cylinder fixing plate 130 and is used to drive the upper guide clamp 200 to move downward; the lower actuator 160 is mounted on the lower cylinder fixing plate 140 and is used to drive the lower guide clamp 300 to move upward, thereby cooperating with the upper guide clamp 200 to clamp the guide tube.

[0034] Both the upper guide clamp 200 and the lower guide clamp 300 include a clamp fixing seat and multiple inserts mounted on the clamp fixing seat. The multiple inserts form slots 240, and the inserts have corresponding notches 221 for clamping the catheter. When the upper driver 150 and the lower driver 160 drive the upper guide clamp 200 and the lower guide clamp 300 to move closer to each other, the inserts on the upper guide clamp 200 and the lower guide clamp 300 insert into each other's slots 240, clamping and guiding the catheter located in the notch 221.

[0035] In some embodiments, the upper positive guide clip 200 and the lower positive guide clip 300 have different structures. Please refer to [link / reference]. Figure 2 The upper guide clip 200 consists of an upper clip fixing seat 210, a pair of first inserts 220, and a pair of second inserts 230. The upper clip fixing seat 210 is T-shaped. The pair of first inserts 220 are respectively disposed on both sides of the upper clip fixing seat 210, and a slot 240 is formed between them. The pair of second inserts 230 are respectively disposed on the outer side of the pair of first inserts 220. The lower end of the first insert 220 protrudes from the second insert 230, and a notch 221 is formed at the lower end of the first insert 220.

[0036] See Figure 2-3 There can be multiple notches 221, which are evenly distributed along the length of the first insert 220. In this embodiment, there are four notches 221 on the first insert 220. Preferably, the notches 221 are triangular in shape. More preferably, a semi-circular notch 222 for accommodating the conduit is formed at the included angle of the notches 221.

[0037] The second insert 230 has an insert block 231 corresponding to the notch 221. The insert block 231 is formed by protruding from the lower end face of the second insert 230, and the shape of the insert block 231 is adapted to the notch 221. Preferably, the insert block 231 is triangular. More preferably, a semi-circular notch 222 for accommodating the conduit is also formed at the apex corner of the insert block 231.

[0038] See Figure 4 The lower guide clip 300 comprises a lower clip fixing base 310, a third insert 320, and a pair of fourth inserts 330. The third insert 320 is located in the middle of the lower clip fixing base 310, and the pair of fourth inserts 330 are located on both sides of the lower clip fixing base 310, forming a slot 240 between the third insert 320 and the pair of fourth inserts 330. In some embodiments, the third insert 320 is integrally formed with the lower clip fixing base 310.

[0039] The upper ends of the third insert 320 and the fourth insert 330 are both provided with notches 221. The position of the notches 221 is the same as that of the notches 221 on the first insert 220, and the shape is also the same. They will not be described in detail here.

[0040] In some embodiments, a cylinder connecting plate 250 is fixed on the upper clamping plate fixing seat 210, and the cylinder connecting plate 250 is fixedly connected to the piston rod of the cylinder. Therefore, the upper driver 150 can drive the upper guide clamping plate 200 to move up and down through the cylinder connecting plate 250.

[0041] In some embodiments, the nasal oxygen cannula alignment device further includes a clamping mechanism 400, which is disposed on the lower alignment clip 300 and corresponds to the position of the notch 221. The clamping mechanism 400 is used to clamp the head of the cannula, thereby better clamping and alignment.

[0042] See Figure 5 The clamping mechanism 400 includes a chuck mounting plate 410, a first half-chuck 420, a linear slide rail 430, a sliding mounting plate 440, a second half-chuck 450, and a clamping cylinder 460; wherein, the chuck mounting plate 410 is fixed on the fourth insert 330, and the first half-chuck 420 is mounted on the chuck mounting plate 410 and corresponds to the position of the notch 221 on the fourth insert 330.

[0043] The linear slide rail 430 is fixed to the lower clamping plate fixing seat 310 and is located below the fourth insert 330. The sliding mounting plate 440 is fixed to the linear slide rail 430, and the second half-clamp 450 is fixed to the sliding mounting plate 440. The clamping cylinder 460 is connected to the sliding mounting plate 440 through the cylinder connecting block 470. Therefore, by the clamping cylinder 460 driving the sliding mounting plate 440 to move along the linear slide rail 430, the second half-clamp 450 can approach the first half-clamp 420, thereby clamping the guide tube head.

[0044] In this embodiment, the clamping mechanism 400 further includes a clamping cylinder fixing plate 480, which is fixed on the lower clamping plate fixing seat 310, and the clamping cylinder 460 is installed on the clamping cylinder fixing plate 480.

[0045] Furthermore, in some embodiments, the clamping cylinder fixing plate 480 is fixedly connected to the piston rod of the lower driver 160, so that the lower driver 160 can drive the clamping mechanism 400 and the lower guide clamping plate 300 to move up and down as a whole.

[0046] In summary, the nasal oxygen cannula alignment device of this utility model can clamp the cannula by driving the upper alignment clip 200 and the lower alignment clip 300 to move closer to each other. Combined with the clamping mechanism 400, it can better align the cannula, making it easier to insert the three-way tube into the cannula, thereby improving the success rate and efficiency of cannula insertion.
