Description

Technical Field

[0001] This utility model relates to the field of oxygen production equipment technology, and more specifically, it relates to a positioning device for oxygen supply equipment. Background Technology

[0002] Oxygen supply equipment typically uses nasal cannulas to deliver oxygen. Nasal cannulas are medical supplies made of soft polyvinyl chloride and silicone rubber, consisting of a bell mouth, a nasal plug, etc., which extend directly into the user's nasal cavity for easy oxygen inhalation.

[0003] Previously, when using nasal oxygen tubes on the market, after putting on the nasal plug, the two tubes were wrapped around behind the ears and then extended to the chin. The tubes were then tightened and limited by the tube sleeves, so that the nasal inhalation connector could be stably connected to the nasal cavity. However, since the tubes were held by the ears, prolonged use could easily compress the blood vessels behind the ears, causing discomfort to the user. In addition, the clamping effect on the tubes varied depending on the user's ear shape, and there was a possibility that the clamping could be unstable and the tubes could fall off. Utility Model Content

[0024] Please see Figure 1-6 The present invention provides the following technical solution:

[0025] A positioning device for an oxygen supply equipment includes a rear band 1 that fits against the back of the user's head. Connecting components 1 and 2 are provided at both ends of the rear band 1. A front band 3 is connected to both connecting components 1 and 2. The length of the front band 3 can be adjusted by the connecting components 1 and 2 to fit against the user's forehead. A top band 4 is connected to both sides of the front band 3. Connecting components 2 and 5 are connected to both top bands 4. The length of the two top bands 4 can be adjusted by the connecting components 2 and 5 to fit against the top of the user's head, thus fixing the positioning device on the user's head. The length of each structure can be flexibly adjusted according to the user's comfort, improving comfort while ensuring stability. A hanging ear 6 is provided below the connecting components 1 and 2 for attaching the nasal cannula of the oxygen supply equipment. The length of the nasal cannula extending beyond the hanging ear 6 on both sides is adjustable.

[0026] The connecting component 2 includes a connecting block 21, which is fixed to both ends of the rear hoop 1. A sliding groove 22 is provided through the connecting block 21, and both ends of the front hoop 3 are slidably connected to the sliding groove 22. An installation groove 23 is provided on the connecting block 21, which is connected to the sliding groove 22. A pressure plate 24 is slidably connected in the installation groove 23, and the pressure plate 24 can abut against the front hoop 3. A connecting rod 26 is provided on the side of the pressure plate 24 away from the front hoop 3. The connecting rod 26 extends out of the connecting block 21, and a spring piece 25 is sleeved on the connecting rod 26. One end of the spring piece 25 is fixed to the bottom of the installation groove 23, and the other end of the spring piece 25 is connected to the pressure plate 24.

[0027] The front hoop 3 is pressed tightly against the groove wall of the slide groove 22 by the pressure plate 24 to fix its length. When the length needs to be adjusted, the connecting rod 26 is pulled outward, and the pressure plate 24 overcomes the elastic force of the spring piece 25 and disengages from the front hoop 3, so that the front hoop 3 can be moved easily.

[0028] The top hoop 4 has a compression groove 42 on the side facing the user's head. A through groove 41 is provided on the bottom of the compression groove 42. The through groove 41 passes through the top hoop 4. The width of the compression groove 42 is greater than the width of the through groove 41. The connecting component 2 5 can abut against the compression groove 42.

[0029] The connecting component 2 5 includes a connecting block 2 51. Adjusting the length of the top hoop 4 allows the connecting block 2 51 to fit against the top of the user's head. A sliding groove 2 52 is provided through the connecting block 2 51. The top hoop 4 is slidably connected to the sliding groove 2 52. A spring 54 is installed inside the connecting block 2 51. The spring 54 is perpendicular to the sliding groove 2 52. A pressure plate 2 53 is connected to the spring 54. The pressure plate 2 53 can press against the bottom of the pressing groove 42, thereby fixing the top hoop 4 to the connecting block 2 51.

[0030] A pressure block 55 is slidably connected to the connecting block 2 51. The pressure block 55 is slidably connected to the through groove 41. The pressure block 55 passes through the through groove 41 and extends to the pressure plate 2 53. When it is necessary to adjust the length of the top hoop 4, the pressure block 55 is pressed down, so that the pressure plate 2 53 moves down against the elastic force of the spring 54. The pressure plate 2 53 is disengaged from the extrusion groove 42, and the length of the top hoop 4 can be easily adjusted.

[0031] The ear loop 6 includes a connecting block 3 61, which is fixed on the connecting component 1 2. A through hole 62 is provided on the connecting block 3 61. A shrink ring 63 is provided on one side of the through hole 62. The shrink ring 63 is frustoconical. The large diameter end of the shrink ring 63 is connected to the opening on one side of the through hole 62. The small diameter end of the shrink ring 63 extends into the through hole 62. Several shrink grooves are provided on the shrink ring 63 along the axial direction. The shrink ring 63 is used to connect the nasal oxygen tube. A locking ring 64 is threaded to the other end of the through hole 62. One end of the locking ring 64 extends into the through hole 62 and abuts against the outer wall of the shrink ring 63.

[0032] The diameter of the contraction ring 63 is equal to the outer diameter of the nasal oxygen tube. The length of the nasal oxygen tube extending out of the loop 6 is adjustable. After adjustment, tighten the locking ring 64. The locking ring 64 pushes the contraction ring 63 to contract a certain distance in the axial direction, thereby locking the nasal oxygen tube and fixing its length.

[0033] Specifically, the positioning device is designed as a headband, with the front band 3 and the rear band 1 connected by a connecting component 1 2. Two top bands 4 are connected to the front band 3, and the ends of the two top bands 4 are connected by a connecting component 2 5. The bottom of the connecting component 1 2 is provided with a hanging ear 6. The head circumference can be adjusted by the connecting component 1 2, and the height of the front band 3 and the rear band 1 on the head can be adjusted by the connecting component 2 5, so that the device can be stably worn on the user's head. The nasal oxygen tube passes through and is fixed on the hanging ear 6, and the length can be flexibly adjusted according to the usage needs, making it more comfortable to use and with a good fixing effect.
