Embodiment 1

[0020] A double-lumen nasal catheter for oxygen inhalation and breath sampling, such as figure 1 As shown, it includes a carbon dioxide collection tube 1 and an oxygen suction tube 2, a separation mechanism 3 is arranged between the carbon dioxide collection tube 1 and the oxygen suction pipe 2, and a carbon dioxide collection tube standard interface 6 is provided at the end of the carbon dioxide collection tube 1 away from the separation mechanism 3, The end of the oxygen inhalation tube 2 far away from the separation mechanism 3 is provided with an oxygen inlet joint 7, and the end of the carbon dioxide collection pipe 1 far away from the separation mechanism 3 is provided with a length adjustment block 5, and two through holes are opened inside the length adjustment block 5 for carbon dioxide collection. The pipe 1 and the oxygen suction pipe 2 pass through two through holes respectively.

[0021] In this embodiment, the carbon dioxide collection tube 1 and the oxygen sucti...

Embodiment 2

[0025] In actual use, the carbon dioxide collection tube 1 and the oxygen inhalation tube 2 are easy to cause falling off when worn, which affects the use of patients. Therefore, we make improvements on the basis of embodiment 1, such as Figure 4 As shown, the middle part of the carbon dioxide collection tube 1 and the oxygen inhalation tube 2 is provided with a clamping mechanism 4, the clamping mechanism 4 includes a clamping chamber 41, and an upper pressing block 42 is arranged above the inside of the clamping chamber 41, and the upper pressing block 42 A lower pressing block 43 is arranged below, two clamping holes 44 are provided between the upper pressing block 42 and the lower pressing block 43, a spring 431 is arranged at the bottom center of the lower pressing block 43, and a pressing hole 43 is arranged on the top of the clamping chamber 41. Rod 45, the top of the pressure rod 45 is tightly welded with a pressure plate 451, the bottom of the pressure rod 45 runs thr...

Abstract

The invention relates to the technical field of nasal catheters, in particular to a double-cavity nasal catheter for oxygen inhalation and exhalation sampling. The double-cavity nasal catheter comprises a carbon dioxide collection tube and an oxygen inhalation tube. A separation mechanism is arranged between the carbon dioxide collection tube and the oxygen inhalation tube. A dioxide collection tube standard interface is arranged at one end, away from the separation mechanism, of the carbon dioxide collection tube. An oxygen inlet joint is arranged at one end, away from the separation mechanism, of the oxygen inhalation tube. The separation mechanism comprises a connecting block. Access ends are arranged symmetrically at two ends of the connecting block. Two connecting channels are arranged inside the connecting block. A threaded hole is formed in the top surface of the other end of each connecting channel. Two nasal tubes are arranged symmetrically at the top of the connecting block.The double-cavity nasal catheter of the invention has the advantages of simple structure and convenient use, the separation mechanism can ensure that the device collects the carbon dioxide gas exhaledfrom nasal cavities of a patient at the time of oxygen inhalation so that the work flow is saved, and a clamping mechanism enables the two catheters to clamp the head of different sizes, so that thedevice does not fall off easily.

Description

technical field [0001] The invention relates to the technical field of nasal catheters, in particular to a dual-chamber nasal catheter for oxygen inhalation and breath sampling. Background technique [0002] The traditional double-nasal oxygen inhalation catheter is one of the most commonly used oxygen inhalation devices in clinical practice. It has the characteristics of convenient operation, high patient comfort, low requirements for oxygen inhalation equipment, and high safety. However, when used for oxygen inhalation in surgery, it only has the function of inhaling oxygen, and cannot take into account the collection function of exhaled gas. The monitoring and analysis of exhaled gas has been widely used in the monitoring of endotracheal intubation patients, and has important clinical significance. It has been reported that the monitoring of end-tidal partial pressure of carbon dioxide is used to monitor non-tracheal intubated patients, and has achieved good results in c...
