Description

Technical Field

[0001] This invention relates to the field of medical respiratory equipment technology, specifically to a multifunctional anesthetic ventilation mask. Background Technology

[0002] In clinical anesthesia and emergency care, ventilation masks are core non-invasive devices for maintaining airway patency and providing anesthetic gases and oxygen. Their performance directly affects anesthetic efficacy and patient safety. Currently, existing anesthetic ventilation masks generally have limited functionality, making it difficult to meet the needs of complex clinical scenarios. Traditional ventilation masks only have basic ventilation functions and lack an effective airway support structure. When patients are under anesthesia and sedation, the tongue is prone to fall back and block the airway, resulting in poor ventilation. In severe cases, it may lead to the risk of hypoxia. At the same time, some masks do not have a chin fixation mechanism, and the patient's head posture is prone to shift, which further aggravates the risk of airway obstruction and increases the workload of medical staff. Regarding sealing, existing masks mostly achieve facial fit through edge padding, but the fit is greatly affected by the differences in the patient's facial contours, which can easily lead to gas leakage. This not only reduces the utilization rate of anesthetic gases but may also affect the surrounding environment and the health of medical staff. Furthermore, the sealing structure at the connection between the ventilation tubing and the mask is simple, and air leakage is prone to occur when rotating and adjusting, affecting ventilation stability. In view of this, we propose a multifunctional anesthetic ventilation mask to solve the existing problems. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional ventilation mask for anesthesia to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional ventilation mask for anesthesia, comprising a mask, a connector, a connecting tube, a carbon dioxide detector, a sealing element, an oropharyngeal ventilation tube head section, an installation element, an installation groove, a chin support, a connector, a connecting chamber, an oropharyngeal ventilation tube tail section, a groove, and a sliding sleeve. The mask has a connector on its upper side, and the mask is movably connected to the connecting tube through the connector. A connecting chamber is provided on one side of the mask, and a sealing element is provided inside the connecting chamber. The sealing element adopts a soft rubber elastic sealing structure. The oropharyngeal ventilation tube head section is detachably connected to the connecting chamber through the sealing element. An oropharyngeal ventilation tube tail section is provided on one side of the oropharyngeal ventilation tube head section, and the oropharyngeal ventilation tube tail section has an arc-shaped structure.

[0005] Preferably, an installation component is provided below the mask, and an installation groove is provided in the installation component. A detachable chin support seat is provided in the installation groove. The chin support seat adopts an arc-shaped support structure and a buffer pad is provided on the surface of the chin support seat. A carbon dioxide detector is provided on one side of the connecting compartment.

[0006] Preferably, the tail section of the oropharyngeal airway has symmetrically formed grooves on the outer wall near the head section of the oropharyngeal airway. The grooves extend axially along the tail section of the oropharyngeal airway. A sliding sleeve is fitted on the groove, and a limiting protrusion is provided on the inner side of the sliding sleeve corresponding to the position of the groove. The limiting protrusion slides in cooperation with the groove.

[0007] Preferably, the face mask is symmetrically fixed with connectors on both sides. The connectors are of the ring-type structure and are detachably connected with elastic ropes made of medical elastic material.

[0008] Preferably, the mask edge is integrally formed with a sealing edge, and an annular groove is formed on the inner side of the sealing edge.

[0009] Preferably, a rotary sealing joint is provided at the connection between the connector and the connecting pipe, and a sealing gasket is provided on the inner side of the rotary sealing joint.

[0010] Preferably, the mounting groove has a positioning hole, and a positioning pin is provided at the connection between the chin support and the mounting groove, the positioning pin being able to be inserted into the positioning hole of the mounting groove.

[0011] Preferably, the end of the connecting pipe away from the connector is provided with a standard interface, which is compatible with the ventilation tubing of existing anesthesia machines and ventilators.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. Medical staff can select a suitable chin support seat according to the patient's age and facial size. By cooperating with the positioning pin and the positioning hole of the mounting slot, it can be detachably installed in the mounting part under the mask. The arc-shaped support structure of the chin support seat fits closely to the patient's chin. The medical sponge cushion on the surface can effectively reduce pressure, stabilize and support the chin, help maintain the patient's head posture, avoid airway obstruction due to head displacement, and significantly improve ventilation stability. The ring-type connectors on both sides of the mask are equipped with medical elastic cords with adjustment buckles. After the elastic cord is wrapped around the patient's head, the tightness can be precisely adjusted by adjusting the buckle to achieve a firm fixation of the mask and prevent displacement or fall off. The breathable cotton layer on the surface of the elastic cord can reduce pressure and friction on the patient's scalp and improve wearing comfort, especially suitable for patients who need long-term ventilation.

[0013] 2. Medical staff install the oropharyngeal airway tip into the connecting chamber using a sealing element. The sealing element employs a soft, elastic sealing structure. The end of the oropharyngeal airway tip is aligned with the pre-cracked seal of the sealing element and inserted inward. Under pressure, the soft rubber material undergoes elastic deformation, and the gap in the pre-cracked seal expands as the oropharyngeal airway tip is inserted, forming a ring-shaped wrapping surface that tightly adheres to the outer wall of the oropharyngeal airway tip. After insertion, the elastic force of the soft rubber continues to act on the outer wall of the oropharyngeal airway tip, achieving detachable fixation between the oropharyngeal airway tip and the connecting chamber, while also forming a double seal. The oropharyngeal airway tail section is made of medical-grade silicone, with an arc-shaped structure that precisely adapts to the physiological curves of the patient's oral cavity and pharynx. The oropharyngeal region effectively opens the airway, preventing the tongue from falling back and obstructing the airway, ensuring unobstructed ventilation. The groove on the outer wall of the oropharyngeal airway tail section slides in conjunction with the limiting protrusion on the inner side of the sliding sleeve. Medical staff can adjust the position of the sliding sleeve according to the depth of the patient's oral cavity to precisely limit the effective insertion length of the airway, avoiding excessive insertion that could damage the pharyngeal mucosa or insufficient insertion that could affect the ventilation effect. The elastic rubber anti-bite pad on the outer side of the sliding sleeve not only effectively prevents the patient from unconsciously biting the airway under anesthesia, but its anti-slip texture also increases the friction with the patient's oral cavity, further fixing the position of the airway. At the same time, the elastic material can buffer the biting force and improve the patient's oral comfort.

[0014] 3. The end of the connecting tube furthest from the connector is quickly connected to the ventilation tubing of the anesthesia machine or ventilator via a standard interface. It is highly adaptable and requires no additional adapters. The anesthetic gas and oxygen mixture from the anesthesia machine or ventilator flows smoothly into the mask through the corrugated connecting tube and connector. The corrugated structure of the connecting tube can be freely bent and adjusted, facilitating adjustments to the tubing layout by medical staff. The anti-condensation coating on the inner wall effectively prevents gas condensation and water droplets from entering the patient's airway and causing choking, ensuring smooth ventilation. The sealing edge of the mask fits snugly against the patient's face, and the medical elastic sealant in the inner annular groove fills gaps in the facial contours, significantly enhancing the seal and preventing gas leakage. The flexible protective edge on the outer side of the sealing edge can be changed to different thicknesses to further adapt to various facial contours, especially suitable for patients with facial trauma, edema, or deformities. The rotary sealing joint and fluororubber sealing gasket at the connection between the connector and the connecting tube maintain good sealing even when the tubing is rotated, preventing leakage and ensuring a stable flow of the mixed gas into the patient's airway.

[0015] 4. The carbon dioxide detector on one side of the connecting chamber has a probe that extends directly into the mask, allowing for real-time and accurate monitoring of the carbon dioxide concentration exhaled by the patient. The data is simultaneously displayed on a screen on the detector's surface, enabling medical staff to intuitively understand the ventilation effect and the patient's respiratory status. When the carbon dioxide concentration exceeds the preset safety range, an alarm device automatically sounds and flashes, reminding medical staff to adjust the parameters of the anesthesia machine or ventilator in a timely manner to prevent hypoxia or over-ventilation, ensuring the safety of the anesthesia ventilation process. A pressure sensor on the mask surface monitors changes in air pressure inside the mask in real time, displaying pressure data and carbon dioxide concentration data simultaneously. Medical staff can combine these two data points to determine if the ventilation system is operating normally, promptly identifying and addressing issues such as tube blockage or leakage. The transparent medical PC material mask allows medical staff to easily observe the position of the ventilation tube inside the patient's mouth, the state of the tongue, and the condition of the facial skin. The antibacterial coating on the inside effectively inhibits bacterial growth, reducing the risk of cross-infection and providing a safer ventilation environment for the patient.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0019] like Figures 1-5As shown, the present invention proposes a multifunctional ventilation mask for anesthesia, comprising a mask 1, a connector 2, a connecting tube 3, a carbon dioxide detector 4, a sealing element 5, an oropharyngeal ventilation tube head section 6, a mounting element 7, a mounting groove 8, a chin support 9, a connector 10, a connecting chamber 11, an oropharyngeal ventilation tube tail section 12, a groove 13, and a sliding sleeve 14. The mask 1 is provided with a connector 2 on its upper side, and the mask 1 is movably connected to the connecting tube 3 through the connector 2. The mask 1 is provided with a connecting chamber 11 on one side, and a sealing element 5 is provided inside the connecting chamber 11. The sealing element 5 adopts a soft rubber elastic sealing structure. The oropharyngeal ventilation tube head section 6 is detachably connected to the connecting chamber 11 through the sealing element 5. The oropharyngeal ventilation tube tail section 12 is provided on one side of the oropharyngeal ventilation tube head section 6, and the oropharyngeal ventilation tube tail section 12 has an arc-shaped structure.

[0020] In an optional embodiment, a mounting component 7 is provided below the mask 1, and a mounting groove 8 is provided in the mounting component 7. A detachable chin support seat 9 is provided in the mounting groove 8. The chin support seat 9 adopts an arc-shaped support structure and a buffer pad is provided on the surface of the chin support seat 9. A carbon dioxide detector 4 is provided on one side of the connecting compartment 11. The carbon dioxide detector 4 connected to one side of the connecting chamber 11 can monitor the concentration of carbon dioxide exhaled by the patient in real time. Medical staff can judge the ventilation effect and the patient's respiratory status based on the monitoring data, and adjust the parameters of the anesthesia machine or ventilator in a timely manner to ensure the safety of the anesthesia ventilation process.

[0021] In an optional embodiment, the tail section 12 of the oropharyngeal airway is provided with symmetrical grooves 13 on the outer side wall near the head section 6 of the oropharyngeal airway. The grooves 13 extend along the axial direction of the tail section 12 of the oropharyngeal airway. A sliding sleeve 14 is fitted on the groove 13, and a limiting protrusion is provided on the inner side of the sliding sleeve 14 corresponding to the position of the groove 13. The limiting protrusion slides in cooperation with the groove 13. Medical staff install the oropharyngeal airway head section 6 into the connecting chamber 11 through the sealing piece 5. The oropharyngeal airway tail section 12 has an arc-shaped structure that can adapt to the physiological curve of the patient's oral cavity and pharynx. After being inserted into the patient's oropharynx, it can effectively open the airway, prevent the tongue from falling back and blocking the airway, and ensure that the ventilation channel is unobstructed. The groove 13 on the outer wall of the oropharyngeal airway tail section 12 slides and engages with the limiting protrusion on the inner side of the sliding sleeve 14. Medical staff can slide and adjust the position of the sliding sleeve 14 according to the depth of the patient's oral cavity to limit the effective insertion length of the airway and avoid insertion that is too deep or too shallow, which would affect the ventilation effect.

[0022] In an optional embodiment, connectors 10 are symmetrically fixed on both sides of the mask 1. The connectors 10 have a ring-type structure and elastic cords are detachably connected to the connectors 10. The elastic cords are made of medical elastic material.

[0023] In an optional embodiment, the mask 1 has an integrally formed sealing edge, and an annular groove 13 is provided on the inner side of the sealing edge.

[0024] In an optional embodiment, a rotary sealing joint is provided at the connection between the connector 2 and the connecting pipe 3, and a sealing gasket is provided on the inner side of the rotary sealing joint.

[0025] In an optional embodiment, a positioning hole is provided in the mounting groove 8, and a positioning pin is provided at the connection between the chin support 9 and the mounting groove 8, the positioning pin being able to be inserted into the positioning hole of the mounting groove 8. Medical staff can detachably install the chin support 9 into the mounting piece 7 below the mask 1 by engaging the positioning pin with the positioning hole of the mounting slot 8. The arc-shaped support structure of the chin support 9 fits the patient's chin, and the cushioning pad on the surface can reduce the pressure and play a role in stabilizing and supporting the chin, helping to maintain the patient's head posture and improve ventilation stability. The ring-type connectors 10 on both sides of the mask 1 are equipped with elastic cords made of medical elastic material. By wrapping the elastic cords around the patient's head and adjusting the tightness, the mask can be firmly fixed and prevented from shifting.

[0026] In an optional embodiment, the end of the connecting pipe 3 away from the connector 2 is provided with a standard interface, which is compatible with the ventilation tubing of existing anesthesia machines and ventilators. Connect the end of the connecting tube 3 away from the connector 2 to the ventilation tubing of the anesthesia machine or ventilator through a standard interface. The anesthetic gas and oxygen mixed airflow output by the anesthesia machine or ventilator enters the mask 1 through the connecting tube 3 and connector 2. The sealing edge of the mask 1 fits snugly against the patient's face. The annular groove 13 on the inner side of the sealing edge can enhance the fit and seal, preventing gas leakage. The rotary sealing joint and sealing gasket at the connection between connector 2 and connecting tube 3 further ensure the airtightness of the ventilation process and ensure that the mixed airflow is stably delivered into the patient's airway.

[0027] The working principle of this invention is as follows: When using this device, medical staff first select a suitable chin support 9, flexible protective edge 18, and anti-bite pad 15 based on the patient's age, weight, facial contours, etc. The chin support 9 is then detachably installed in the mounting component 7 below the mask 1 by engaging the positioning pin with the positioning hole of the mounting groove 8. The elastic washer between the positioning pin and the positioning hole enhances the connection stability. The arc-shaped support structure of the chin support 9 conforms to the patient's chin, and the medical sponge cushioning pad on the surface reduces pressure, stably supports the chin, helps maintain the patient's head posture, and improves ventilation stability. A protective edge of appropriate thickness is selected according to the patient's facial contours to ensure a good seal and comfort. The mask 1 is fitted with medical elastic cords with adjustable buckles on the ring-type connectors 10 on both sides. The elastic cords are wrapped around the patient's head, and the tightness is precisely adjusted using the buckles to securely fix the mask 1. The breathable cotton layer on the surface of the elastic cords reduces pressure on the patient's scalp. Medical personnel install the oropharyngeal airway head section 6 into the connecting chamber 11 via the sealing piece 5. The oropharyngeal airway tail section 12 is an arc-shaped medical silicone structure, adapted to the physiological curve of the patient's oral cavity and pharynx. After insertion into the patient's oropharynx, it effectively opens the airway and prevents the tongue from falling back and obstructing the airway. The position of the sliding sleeve 14 is adjusted according to the depth of the patient's oral cavity. The insertion length of the airway is adjusted through the cooperation of the limiting protrusion and the groove 13. Precise positioning and the anti-bite pad 15 on the outer side of the sliding sleeve 14 prevent patients from biting and damaging the ventilation tube, while also improving oral comfort. The end of the connecting tube 3 furthest from the connector 2 is connected to the ventilation line of the anesthesia machine or ventilator via a standard interface. After rotating the connecting tube 3 to the appropriate direction, the angle of the rotary sealing joint is fixed by adjusting the knob 17 to prevent the tube from rotating arbitrarily. The anesthetic gas and oxygen mixed airflow from the anesthesia machine or ventilator enters the mask 1 through the connecting tube 3 and connector 2. The sealing edge of the mask 1 fits snugly against the patient's face. The elastic sealant in the annular groove 13 and the flexible protective edge 18 on the outside enhance the seal, preventing gas leakage. The rotary sealing joint and sealing gasket further... To ensure airtightness during ventilation, the carbon dioxide detector 4 monitors the concentration of carbon dioxide in the patient's exhaled breath in real time, and the pressure sensor 16 monitors the changes in air pressure inside the mask 1. Both data are displayed on the screen simultaneously. When the carbon dioxide concentration exceeds the preset range, the alarm device emits an audible and visual alarm, and medical staff can adjust the parameters of the anesthesia machine or ventilator in a timely manner. The transparent mask 1 allows medical staff to observe the inside of the patient's mouth and facial condition. The antibacterial coating on the inside inhibits bacterial growth and reduces the risk of cross-infection. After use, medical staff disassemble the elastic cord, oropharyngeal airway assembly, chin support 9, and other components in sequence for cleaning, disinfection, or replacement for the next use.
