Description

A mask and pipeline for inhaling nitric oxide

Technical Field

The utility model relates to a mask and a pipeline for nitric oxide inhalation, belonging to the technical field of medical equipment.

Background Art

In recent years, inhaled nitric oxide (iNO) therapy has been widely used in critically ill patients, especially those with acute respiratory distress syndrome (ARDS) or pulmonary hypertension. In pathological conditions, pulmonary circulation and oxygenation are severely affected, leading to life-threatening conditions for patients, and iNO is considered an effective treatment. Nitric oxide (NO) is the main regulator of vascular smooth muscle tone, and it has been confirmed that it is the endothelium-derived relaxing factor (EDRF); the decrease in pulmonary vascular resistance after birth is mediated by NO; and very little NO is absorbed into the blood and enters the body, with a biological half-life of only a few seconds, and has a very strong affinity for hemoglobin (1500 times that of carbon monoxide). In the past few years, research on inhaled nitric oxide therapy has made significant progress, especially in understanding the mechanism of action of nitric oxide and optimizing treatment options; studies have shown that iNO can promote pulmonary vascular relaxation, selectively dilate pulmonary blood vessels, lower pulmonary artery pressure, reduce intrapulmonary shunt, and improve ventilation/perfusion ratio by increasing the level of cyclic guanosine monophosphate (cGMP) in pulmonary artery endothelial cells, thereby improving lung function and oxygenation; in addition, iNO also has the effect of inhibiting inflammatory response and reducing lung damage, which is particularly important for the treatment of ARDS patients.

As the understanding of iNO therapy continues to deepen, clinicians have begun to realize its potential application value in different types of patients. In addition to patients with invasive mechanical ventilation, some patients with non-invasive mechanical ventilation can also benefit from iNO therapy. These patients may suffer from chronic lung diseases, such as chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) or cystic fibrosis (CF); or respiratory failure caused by acute ventilation-perfusion ratio imbalance, such as acute pulmonary embolism, atelectasis, etc.

Therefore, there is an urgent need in this field to develop a mask and tube specifically for nitric oxide inhalation therapy, to provide effective treatment options for more patients, and to hopefully improve patients' recovery and survival rates.

Summary of the invention

The purpose of the utility model is to solve the problem of lack of masks and pipelines required for nitric oxide inhalation treatment in the prior art.

In order to achieve the purpose of solving the above-mentioned problems, the technical solution adopted by the utility model is to provide a mask and pipeline for nitric oxide inhalation, including a mask body, a mask one-way exhalation valve, a NO delivery interface end and an oxygen delivery conduit are arranged on the outside of the mask body, and the NO delivery interface end is connected to the NO delivery connecting pipe; a NO concentration monitoring interface end is arranged inside the mask body, and the NO concentration monitoring interface end is connected to the NO concentration monitoring connecting pipe.

Preferably, in the mask body, an adjustable damping slide rail is also provided at the position of the patient's nasal cavity to help ensure the fit and stability of the monitoring channel with the patient's nasal cavity and body position.

Further preferably, the NO concentration monitoring interface end is arranged on an adjustable damping slide rail.

Preferably, a detachable filtering device is provided inside the mask body at a position opposite to the NO concentration monitoring interface end.

Preferably, the mask body is also provided with a three-point adjustable headband to ensure that the mask fits tightly between the patient's mouth and nose.

Preferably, a multifunctional extension tube is provided between the mask body and the NO delivery interface end.

Further preferably, the multifunctional extension tube is provided with an interface which can also be used for aerosol inhalation treatment.

Preferably, a flow monitoring probe for monitoring the flow of inhaled gas is provided at the lower portion of the NO delivery interface end.

Further preferably, the oxygen delivery conduit is arranged below the flow monitoring probe.

Compared with the prior art, the utility model has the following beneficial effects:

1. It is easy to implement in clinical practice, with simple operation, cheap consumables, and light appearance. By adjusting the position of the NO concentration monitoring interface, the target NO concentration can be obtained more accurately, which can provide better quantitative significance for the therapeutic dose and improve monitoring accuracy. It can also save the use of consumables and save costs for patients, and has strong clinical practicality.

DETAILED DESCRIPTION

In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

As shown in Fig. 1 and Fig. 2, the utility model provides a mask and pipeline for nitric oxide inhalation. When in use, the mask body 1 is worn on the patient's face, and the NO concentration monitoring interface end 3 and the three-point adjustable headband 7 on the adjustable damping slide rail 2 are adjusted to match the patient's nasal cavity and body position. The patient inhales NO and oxygen through the NO delivery connecting tube 10, the NO delivery interface end 9, the detachable filter device 5 used for atomization inhalation treatment arranged on the NO delivery interface end 9, and the oxygen delivery conduit 12, and exhales gas through the mask's one-way exhalation valve 6; the treatment personnel monitor the nitric oxide concentration inhaled by the patient in real time and accurately through the flow monitoring probe 11 and the NO concentration monitoring connecting tube 4 to ensure that the patient receives an appropriate treatment dose, and the relative distance between the NO delivery end and the monitoring end is maintained through the multifunctional extension tube 8, and the interface on the multifunctional extension tube 8 can also be used for atomization inhalation treatment.

The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model.
