Description

Technical Field

[0001] The invention relates to the technical field of non-invasive masks, and in particular to a bronchoscope non-invasive mask. Background Art

[0002] Non-invasive masks are divided into nasal masks, oronasal masks, nasal pillow masks, full-face masks, oral masks and helmet masks, which are generally composed of a mask body, a sealing pad, a suffocation valve, an air inlet, a brow support, and a fixed headband. The mask body is connected to the sealing pad. When the mask is used, the sealing pad contacts the patient's face. There is an air inlet in the middle of the bottom of the mask body, which is connected to the ventilator pipeline. There are four headband fixing grooves on the mask, two on the brow support, and the other two on the quick-release buckles. The four straps of the headband pass through the fixing grooves from the inside to the outside. After the ventilator is prepared and connected to the breathing pipeline, the mask is buckled on the patient's face, and the fixed headband is adjusted to a comfortable position. The mask sealing pad is close to the patient's face to ensure no gaps. The ventilator pipeline is connected to the mask interface. The suffocation valve is located near the interface. Turn on the ventilator to start treatment. If it is a dual-circuit ventilator, there is no need for a leak hole on the mask. If it is a single-circuit ventilator, a leak hole is required on the mask.

[0003] Since the interface of the existing non-invasive mask connected to the ventilator pipeline is generally an arc-shaped right-angle interface, there is no small hole on the interface that can be opened or closed for the entry and exit of the bronchoscope, and there is no such small hole on the main body of the non-invasive mask that can be used for bronchoscope. Therefore, there is no non-invasive mask that can be used for bedside bronchoscopy in the intensive care unit. When the patient with a more serious condition in the intensive care unit cannot be separated from the non-invasive ventilator, if the patient has a lot of airway secretions and needs a bedside bronchoscopy under intravenous anesthesia, there is no suitable non-invasive mask that can be used directly for bronchoscopy. If the patient is replaced with a nasal cannula or high-flow, the patient's oxygen and vital signs are difficult to maintain stability during the bronchoscopy, and the risk is relatively high. If a bronchoscopy is performed under general anesthesia, there is a risk of difficulty in extubation;

[0004] Since there are no small holes or cracks on the non-invasive mask for placing a gastric tube, when patients with indwelling gastric tubes wear non-invasive masks, a large amount of air leakage at the compression point of the gastric tube often causes the ventilator to stop supplying air, which is very dangerous in clinical practice. Some medical staff will therefore tighten the fixed headband, causing patients to have headaches, facial pressure sores and other problems;

[0005] There is no non-invasive mask that is compatible with both single-circuit non-invasive ventilators and dual-circuit non-invasive ventilators. Some non-invasive masks have leak holes and can only be used with single-circuit non-invasive ventilators. When used with dual-circuit ventilators, it is clinically necessary to cover the leak holes with tape to prevent leakage. Other non-invasive masks do not have leak holes and can only be used with dual-circuit non-invasive ventilators. When used with single-circuit non-invasive ventilators, an additional leak valve is required.

[0006] In summary, the existing non-invasive masks are due to design limitations, insufficient consideration of patient experience and safety, and insufficient foresight of the diversity of clinical needs. The inability to be used with a bronchoscope makes it difficult to perform bedside bronchoscopy on patients in the intensive care unit who are seriously ill and cannot be weaned off the ventilator. The lack of a small hole for placing a gastric tube makes it easy for patients with indwelling gastric tubes to leak when using a non-invasive mask, increasing clinical risks and patient discomfort. In addition, there is a lack of masks on the market that are compatible with both single-circuit and dual-circuit non-invasive ventilators, which requires additional processing or accessories during use, increasing the complexity of clinical operations. For this reason, we propose a bronchoscope non-invasive mask. Summary of the invention

[0007] The purpose of the present invention is to solve the problems of existing non-invasive masks due to design limitations, insufficient consideration of patient experience and safety, and insufficient foresight of the diversity of clinical needs. It cannot be used with a bronchoscope, which makes it difficult for patients in the intensive care unit who are seriously ill and cannot be separated from the ventilator to undergo bedside bronchoscopy. The lack of a small hole for placing a gastric tube makes it easy for patients with indwelling gastric tubes to leak when using a non-invasive mask, increasing clinical risks and patient discomfort. In addition, there is a lack of masks on the market that are compatible with both single-circuit and dual-circuit non-invasive ventilators, which requires additional processing or accessories during use, increasing the complexity of clinical operations.

[0015] Furthermore, the annular contact pad is made of elastic silicone material, and the inner wall of the gastric tube perforation is fixedly connected with a circle of contact soft rubber.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention provides a mask body that is worn at the patient's mouth.

[0018] 2. The present invention provides an annular contact pad that contacts the patient's face to improve the sealing between the edge of the mask body and the patient's face. In addition, the gastric tube crack and gastric tube perforation are provided, so when used for patients with gastric tubes, the annular contact pad is removed, the gastric tube is inserted into the gastric tube perforation, and then re-inserted into the contact pad holder to maintain the sealing of the contact position between the gastric tube and the gastric tube perforation, thereby reducing a large amount of air leakage at the gastric tube compression point caused by the patient with a gastric tube wearing a non-invasive mask, which is beneficial for the ventilator to more accurately monitor the patient's spontaneous breathing airflow, is not easily disturbed by non-permitted air leakage, ensures the stability of the non-invasive ventilator airflow, and does not cause excessive air delivery or automatic suspension of the ventilator due to a large amount of air leakage, which is beneficial for improving the cooperation between the patient and the ventilator and reducing the occurrence of clinical risks.

[0019] 3. The leakage hole of the present invention is located in the middle of the bottom of the mask body, and a covered breathing valve is provided on the leakage hole. When a single-circuit non-invasive ventilator is used, the covered breathing valve is opened, the leakage hole is exposed, and the patient can exhale through it. When a dual-circuit non-invasive ventilator is used, the covered breathing valve is closed, and the leakage hole is covered by the covered breathing valve, so that no air can leak.
