Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a breathing mask for anesthesia bronchoscopy. Background Technology
[0002] Bronchoscopy is performed by a physician who inserts a thin, fiberoptic bronchoscope through the nose or mouth into the patient's lower respiratory tract, passing through the glottis into the trachea and distal bronchi. Even when performed under anesthesia, the procedure can still cause severe coughing, often accompanied by secretions. At this time, the respiratory tract and mouth are open, which can lead to the spread of respiratory bacteria or viruses, easily causing cross-infection among the medical staff performing the procedure.
[0003] While there are protective masks specifically designed for bronchoscopy available on the market, they only have an opening at the nasal cavity and are only suitable for conscious patients. However, for patients under intravenous anesthesia, the patient is in anesthetized state during the procedure. If the patient has a lot of oral secretions during the procedure, even after removing the mask, it is difficult to insert the suction catheter into the patient's oropharynx for suction, increasing the risk of aspiration and coughing, and increasing the probability of pneumonia. Furthermore, if the patient has nasal damage or edema, making nasal access unsuitable, and the procedure can only be performed through the mouth, the patient must bite down on a mouthguard. In this case, only a nasal cannula can be used for oxygenation, which cannot effectively prevent the spread of secretions (i.e., respiratory viruses or bacteria) produced during coughing, increasing the risk of cross-infection for medical staff.
[0004] Therefore, there is a need in the field for a new type of oxygen supply mask to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a breathing mask for anesthesia bronchoscopy, which provides oxygen to the patient by covering the patient with the mask body, and the mask body is provided with a first protruding ring and a first mounting hole at the corresponding positions of the mouth and nose, respectively, so that the more suitable method can be selected to operate on the patient according to the different conditions of the patient.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a breathing mask for anesthesia bronchoscopy, including a mask body and a mouth pad. The mask body has a first mounting hole at the position corresponding to the mouth. The surface of the mask body has a convex shell, which corresponds to the position of the nose. The lower surface of the convex shell has a first convex ring for inserting the bronchoscopy. The upper surface of the convex shell has a first air inlet ring. The first convex ring and the first air inlet ring are connected to the inner side of the mask body. The mouth pad is adapted to the first mounting hole and extends into the mask body from the first mounting hole.
[0007] Furthermore, the breathing mask also includes a first sealing socket, which is inserted into the first protruding ring and sealed.
[0008] The first sealing socket end face has a clearance groove, and the bottom of the clearance groove is provided with a bronchoscope inlet.
[0009] Furthermore, a limiting ring is formed on the outer peripheral surface of the first sealing socket, and the limiting ring abuts against the lower surface of the first convex ring.
[0010] Furthermore, a first sealing annular groove is formed on the circumferential surface of the first sealing socket, and a sealing ring is disposed in the first sealing annular groove.
[0011] Furthermore, the breathing mask also includes a guide device. The convex shell surface is provided with a through hole. The guide device includes a guide metal wire. One end of the guide metal wire passes through the through hole and is provided with a guide ring inside the mask body. The guide ring is sleeved on the outer periphery of the bronchoscope.
[0012] Furthermore, the guide metal wire is sealed to the through hole.
[0013] Furthermore, the mouth pad is a cylindrical tube, and a limiting protrusion is formed on the outer periphery of the outer end of the mouth pad, which is locked to the end face of the mask body.
[0014] Furthermore, the mouth gasket is sealed to the first mounting hole.
[0015] Furthermore, a plug-in sealing plug is provided at the opening on the outward side of the mouth gasket.
[0016] Furthermore, the mouth pad has an annular groove formed on the outer peripheral surface of the inner side of the mask body, and a flexible bite sleeve is provided in the annular groove.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention provides a breathing mask for bronchoscopy under anesthesia, which is simple in structure, easy to operate, and comfortable to wear. The mask body has a first mounting hole, and a mouth pad is placed at the first mounting hole. Before performing bronchoscopy under anesthesia, the mask body is placed over the patient's mouth and nose using a securing strap, and the mouth pad is placed into the patient's mouth. The patient bites down on the mouth pad, and the mask body is then secured before anesthesia is administered. During bronchoscopy under anesthesia, the bronchoscope can be directly inserted into the patient's nasal cavity through the first convex ring for examination (when the bronchoscope enters the mask body, the opening of the first convex ring needs to be blocked). This ensures sufficient oxygen concentration and, because the mouth and nose are within the mask, reduces the transmission of respiratory bacteria or viruses, lowering the cross-infection rate among medical staff. If excessive oropharyngeal secretions occur during anesthesia, the obstruction at the mouth pad can be removed directly through the mask body, and a suction catheter can be inserted for suction, reducing the incidence of aspiration. Furthermore, if nasal edema or other conditions prevent nasal access after the bronchoscope is inserted into the nasal cavity under anesthesia, the bronchoscope can be directly inserted through the mouth pad of the mask body to perform the relevant examination. While ensuring the above advantages, the examination can be performed directly without waiting for the patient to wake up and the mouth pad to be reinserted, which increases both patient comfort and examination efficiency.

[0029] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0030] Example 1
[0031] like Figures 1-5 As shown, this embodiment provides a breathing mask for anesthesia bronchoscopy 6, including a mask body 1, a mouth pad 2, a first sealing socket 3, and a fixing strap.
[0032] The mask body 1 has a first mounting hole 11 at the position corresponding to the mouth. The mouth pad 2 is adapted to the first mounting hole 11 and extends into the mask body 1 from the first mounting hole 11. Specifically, the mouth pad 2 is a cylindrical tube with an elliptical cross section. A limiting protrusion ring 21 is formed on the outer periphery of the outer end of the mouth pad 2. The limiting protrusion ring 21 is locked with the end face of the mask body 1. The mouth pad 2 and the first mounting hole 11 are sealed together. This is achieved by setting a sealing ring between the first mounting hole 11 and the mouth pad 2.
[0033] Preferably, the mouth pad 2 has an annular groove 22 formed on the outer peripheral surface of the inner side of the mask body 1, and a flexible bite sleeve 221 is provided in the annular groove 22. The flexible bite sleeve 221 is made of silicone material, and the design of the flexible bite sleeve 221 can make the patient feel more comfortable when biting down.
[0034] The mouth pad 2 has a pull-out sealing plug at its outward-facing opening. When not in use, the mouth pad 2 is sealed with the sealing plug to prevent air leakage. The sealing plug is removed only when examination or suctioning is required through the mouth pad 2. In another embodiment, to prevent a decrease in oxygen content inside the mask body 1 due to the sealing plug being removed, an insertion hole can be made on the surface of the sealing plug. This insertion hole is adapted to either the outer diameter of the bronchoscope 6 or the outer diameter of the suction tube, depending on the situation. Since the outer materials of the bronchoscope 6 and the suction tube are both rubber or elastic plastic, they remain sealed when inserted through the insertion hole.
[0035] The mask body 1 has a convex shell 12 on its surface, which corresponds to the nose position. A first convex ring 121 is provided on the lower surface of the convex shell 12. The first convex ring 121 is used to allow the bronchoscope 6 to be inserted. A first air intake ring 122 is provided on the upper surface of the convex shell 12. The first convex ring 121 and the first air intake ring 122 are connected to the inner side of the mask body 1. The first air intake ring 122 is used to connect with the oxygen supply tube.
[0036] The first sealing socket 3 is inserted into the first protruding ring 121 and sealed. Specifically, a first sealing annular groove is formed on the circumferential surface of the first sealing socket 3, and a sealing ring is provided in the first sealing annular groove. The end face of the first sealing socket 3 has a clearance groove, and two bronchoscope inlets are provided at the bottom of the clearance groove. The two bronchoscope inlets correspond to the two nasal inlets respectively. When not in use, the two bronchoscope inlets need to be plugged with plugs. The reason for providing two bronchoscope inlets is that the appropriate bronchoscope inlet can be selected for operation according to the patient's condition, making it more adaptable. When the bronchoscope 6 is inserted into the nasal cavity through the bronchoscope inlet, the bronchoscope 6 is in a sealed state during the insertion process because the outer material of the bronchoscope 6 is rubber or plastic with a certain degree of elasticity. A limiting ring platform 31 is formed on the outer circumferential surface of the first sealing socket 3, and the limiting ring platform 31 abuts against the lower surface of the first protruding ring 121.
[0037] The mask body 1 has fixing seats 4 on both sides of its surface. The fixing seats 4 have fixing holes. The fixing strap is an elastic band. The two ends of the fixing strap pass through the fixing holes and are locked on the fixing seats 4. The mask body 1 is fixed by pulling the elastic band and putting it on the back of the patient's head.
[0038] Working principle: Before performing bronchoscopy 6 under anesthesia, the mask body 1 is placed over the patient's mouth and nose using a fixing strap, and the mouth pad 2 is placed in the patient's mouth. After the patient bites down on the mouth pad 2 and the mask body 1 is fixed, anesthesia is administered. During bronchoscopy 6 under anesthesia, the bronchoscope 6 can be directly inserted into the patient's nasal cavity through the first convex ring 121 for examination. The tube of the bronchoscope 6 passes through the bronchoscope inlet of the first sealing socket 3, and the detection end of the bronchoscope 6 is located in the relief groove of the first sealing socket 3. Then, the first sealing socket 3 is inserted into the first convex ring 121. This process ensures sufficient oxygen concentration, and because the mouth and nose are within the mask, it also reduces the transmission of respiratory bacteria or viruses, reducing the cross-infection rate of medical staff. If there is excessive secretion in the oropharynx during anesthesia, the obstruction at the mouth pad 2 can be removed directly through the mouth pad 2 of the mask body 1, and a suction catheter can be inserted for suction, which can reduce the incidence of coughing and aspiration. Furthermore, if nasal edema or other conditions prevent the bronchoscope from entering the nasal cavity after anesthesia, the bronchoscope can be directly inserted through the mouth pad 2 of the mask body 1 to perform relevant examinations. While ensuring the above advantages, the examination can be performed directly without waiting for the patient to wake up and re-insert the mouth pad 2, which increases patient comfort and improves examination efficiency.
[0039] Example 2
[0040] like Figures 5-9 As shown, the difference between this embodiment and Embodiment 1 is that the breathing mask in this embodiment also includes a guide device 5. The surface of the convex shell 12 is provided with two through holes 123, which correspond to the two bronchoscope inlets respectively. The guide device 5 includes a guide metal wire 51, and a rubber sleeve is provided on the outer periphery of the guide metal wire 51. The guide metal wire 51 passes through the through hole 123. One end of the guide metal wire 51 located inside the mask body 1 is provided with a guide ring 52. The guide ring 52 is sleeved on the outer periphery of the bronchoscope 6. By pulling or pushing the guide metal wire 51, the bronchoscope 6 can be controlled to enter the nasal cavity at a more suitable angle.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope.
