Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a 3D printed personalized assembly anesthesia mask. Background Art

[0002] Anesthesia induction is the first stage of general anesthesia. It is the process of using anesthetic drugs, including sedatives, analgesics, intravenous or inhaled anesthetics, and muscle relaxants, to allow the patient to move from a conscious state to an anesthetized state where surgical operations can be performed. During the inhalation anesthesia induction process, an anesthesia mask is required to assist. During the anesthesia process, the anesthesia mask is an important device used to deliver anesthetic gas or oxygen to the patient.

[0003] Traditional anesthesia masks usually adopt standard sizes. Although they can meet the basic sealing requirements in terms of functionality, they often cannot provide the best comfort and sealing for every patient due to the lack of personalized design. In addition, during use, the gas produced by the patient's breathing will produce water vapor due to the difference between the ambient temperature and the temperature inside the anesthesia mask. The condensed water vapor can easily flow to the patient's face and mouth and nose, causing discomfort to the patient and easily being inhaled into the respiratory tract by the patient, causing safety hazards. At the same time, due to different ways of pressing the mask, the force of the bottom of the mask acting on the patient's face is different, which can easily cause gas leakage. Therefore, the present application provides a 3D printed personalized assembly anesthesia mask to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a 3D printed personalized assembly anesthesia mask to solve the problem that the existing anesthesia masks lack personalized design and cannot provide the best comfort and sealing for each patient. Moreover, during use, the gas generated by the patient's breathing will produce water vapor due to the difference between the ambient temperature and the temperature inside the anesthesia mask.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a 3D printed personalized assembly anesthesia mask, including a mask base 1, a base pad mechanism 2, a connecting mechanism 3, a fixing mechanism 4 and a drainage mechanism 5, the base pad mechanism 2 is arranged at the bottom end of the mask base 1, and a connecting ring seat 13 is fixedly connected to the bottom surface of the mask base 1, the base pad mechanism 2 is made by 3D printing, and is used to fit the patient's face to seal the bottom end of the mask base 1, the connecting mechanism 3 is arranged at the top of the mask base 1, the connecting mechanism 3 is used to connect the oxygen supply and anesthesia gas delivery pipes, the fixing mechanism 4 is arranged on both sides of the connecting mechanism 3, the fixing mechanism 4 is used to tie the mask strap to tie and fix the entire mask, the drainage mechanism 5 is arranged on the outer wall of the base pad mechanism 2, and the drainage mechanism 5 is used to discharge the liquid inside the base pad mechanism 2.

[0039] The mask base 1 equipped with the bottom pad mechanism 2 is buckled and covered on the patient's mouth and nose. The bottom pad mechanism 2 made by 3D printing can perfectly match the patient's facial contour, and cooperate with the mask base 1 to cover and seal the patient's mouth and nose, thereby meeting the anesthetic gas delivery requirements for induced anesthesia. The connecting pipe mechanism 3 arranged at the top of the mask base 1 facilitates the connection and locking of the conduit for delivering anesthetic gas or oxygen, thereby improving the tightness of the connection between the entire anesthesia mask and the anesthesia air supply pipe. The fixing mechanisms 4 arranged on both sides of the connecting pipe mechanism 3 facilitate the use of the binding belt to cooperate with the fixing mechanism 4 to fix the entire anesthesia mask to the patient's head during the use of the anesthesia mask. The drainage mechanism 5 arranged on the outer wall of the bottom pad mechanism 2 facilitates the discharge of the water vapor accumulated in the anesthesia mask due to the patient's breathing due to long-term use, thereby reducing the amount of water vapor inside the anesthesia mask, thereby improving the comfort of the patient in wearing the anesthesia mask.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, the base pad mechanism 2 includes a mask base pad 14 which is snap-fitted to the bottom end of the connecting ring seat 13, a buckle slot 29 is provided on the top surface of the mask base pad 14, the connecting ring seat 13 is located inside the buckle slot 29, and an expansion cavity 15 is provided inside the mask base pad 14. The buckle slot 29 provided on the top surface of the mask base pad 14 facilitates quick plugging of the connecting ring seat 13, thereby completing the quick connection between the base pad mechanism 2 and the mask base 1, and the expansion cavity 15 provided inside the mask base pad 14 facilitates the use of the expansion cavity 15 to improve the overall softness of the mask base pad 14, and then when using the anesthesia mask, the mask base pad 14 can be more adapted to the patient's facial contour after being compressed, so that it can fit closely to the patient's face to avoid gas leakage.

[0041] like Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, a pressing piece 16 is fixedly connected to the top of the expansion cavity 15, and the pressing piece 16 is V-shaped and inclined toward the outer wall of the mask base pad 14. The two ends of the top of the pressing piece 16 are respectively located on both sides of the inner wall of the buckle groove 29, and plug-in grooves 23 are provided on both sides of the connecting ring seat 13. The top of the pressing piece 16 is clipped inside the plug-in groove 23, and the bottom of the pressing piece 16 is fixedly connected to an elastic piece 22. The elastic piece 22 is C-shaped, and the top of the elastic piece 22 is fixedly connected to a filling strip 27 at one end away from the pressing piece 16. The pressing piece 16, the elastic piece 22 and the filling strip 27 are an integrated structure. The pressing piece 16 fixedly connected to the top of the expansion cavity 15 is convenient for applying to the top of the mask base pad 14. The pressure is transmitted to the surface of the elastic sheet 22 at the bottom of the pressing sheet 16 through the pressing sheet 16, so that the elastic sheet 22 is used to guide the downward pressure generated by the entire anesthesia mask. The downward pressure of the pressing sheet 16 can be guided by the filling strip 27 fixedly connected to the top of the elastic sheet 22 away from one end of the pressing sheet 16, so that the downward pressure is evenly guided to the surface of the elastic sheet 22, thereby avoiding uneven force on the mask base pad 14, which is prone to excessive tilting, and the mask base pad 14 cannot fit the patient's face tightly. At the same time, the pressing sheet 16 with the two ends of the top located on both sides of the inner wall of the buckle groove 29 can generate a clamping force to improve the firmness between the connecting ring seat 13 and the plug groove 23.

[0042] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the bottom end of the pressing sheet 16 is provided with a guide groove 17, the outer wall of the mask bottom pad 14 is provided with a drainage hole 18, the guide groove 17 and the drainage hole 18 are connected to each other, a liquid storage tank 24 is provided at the connection between the top of the connecting ring seat 13 and the inner wall of the mask base 1, and a drainage groove 25 is provided at the bottom of the liquid storage tank 24. A liquid through hole 26 is provided at the bottom end of the buckle groove 29, and the liquid through hole 26 and the drainage groove 25 are connected to each other. The bottom end of the liquid through hole 26 is located inside the pressing sheet 16, and is connected to the top of the connecting ring seat 13 and the inner wall of the mask base 1 The opened liquid storage tank 24 can store the liquid condensed on the inner wall of the mask base 1 due to the temperature difference when the patient breathes. The liquid is discharged into the drainage tank 25 through the liquid storage tank 24, and then discharged into the groove body of the pressing plate 16 in the expansion cavity 15 through the liquid through hole 26. The pressing plate 16 inclined toward the outer wall of the mask base pad 14 is used to guide the liquid, and the liquid is discharged through the drainage hole 18 opened on the outer wall of the mask base pad 14. The V-shaped pressing plate 16 can store liquid inside, thereby increasing the collection and storage capacity of the entire mask liquid.

[0043] like Figure 1 and Figure 3As shown, the connecting mechanism 3 includes a ventilation tube 8 and an expansion tube 9 fixedly connected to the top of the mask base 1, the expansion tube 9 is located on the outside of the ventilation tube 8, and a fastening nut 11 is installed on the surface of the expansion tube 9 by thread rotation, and a pressure strip 10 is fixedly connected to the inner wall of the expansion tube 9. By inserting the anesthetic gas delivery tube on the surface of the ventilation tube 8 and then rotating the fastening nut 11, the fastening nut 11 is moved along the thread of the surface of the expansion tube 9 to tighten the expansion tube 9, thereby clamping the anesthetic gas delivery tube so that it fits tightly to the ventilation tube 8 to avoid the situation where the anesthetic gas delivery tube connection is easily detached. At the same time, the pressure strip 10 fixedly connected to the inner wall of the expansion tube 9 can apply pressure to the local part of the anesthetic gas delivery tube, thereby increasing the pressure at the joint between the anesthetic gas delivery tube and the ventilation tube 8, thereby further improving the sealing effect between the anesthetic gas delivery tube and the ventilation tube 8.

[0044] like Figure 1 , Figure 5 and Figure 6 As shown, the drainage mechanism 5 includes a drainage hose 19 fixedly connected to the outer wall of the mask base pad 14, one end of the drainage hose 19 is interconnected with the drainage hole 18, and the other end of the drainage hose 19 is fixedly connected to the liquid storage bag 20. A flow regulator 21 is installed on the outer wall of the drainage hose 19. By fixing the drainage hose 19 on the outer wall of the mask base pad 14, the liquid discharged from the drainage hole 18 can be discharged into the liquid storage bag 20 through the drainage hose 19. The flow regulator 21 installed on the outer wall of the drainage hose 19 facilitates the use of the flow regulator 21 to adjust the flow of the drainage hose 19, thereby discharging the liquid into the liquid storage bag 20. When it is necessary to discharge the liquid in the liquid storage bag 20, the flow regulator 21 can be used to intercept and close the drainage hose 19, thereby avoiding gas leakage in the mask when discharging the liquid in the liquid storage bag 20.

[0045] like Figure 1 and Figure 3As shown, the fixing mechanism 4 includes two groups of positioning rods 6 fixedly connected to the top of the mask base 1, the two groups of positioning rods 6 are respectively located on both sides of the expansion tube 9, and the tops of the two groups of positioning rods 6 are fixedly connected with rubber soft plates 7, and the tops of the rubber soft plates 7 are installed with extension rods 12 through mounting holes. Through the arrangement of the two groups of positioning rods 6, it is convenient to tie the straps used to fix the entire anesthesia mask, so that the medical staff can wear the anesthesia mask on the patient's head. At the same time, the rubber soft plates 7 located at the tops of the two groups of positioning rods 6 are convenient for medical staff to grab the anesthesia gas delivery tube and the ventilation When the connection of tube 8 applies pressure to the entire anesthesia mask, the palm of the medical staff is supported, thereby improving the comfort of the medical staff in taking the anesthesia mask, and the downward pressure generated by the medical staff pressing down the anesthesia mask can be evenly transmitted to the entire surface of the anesthesia mask. The extension rod 12 installed through the mounting hole on the surface of the rubber soft plate 7 can be used to induce anesthesia for child patients, and ornaments used to soothe children's fear can be hung to reduce the fear of the child patients about the anesthesia mask. The extension rod 12 installed by the buckle can be disassembled when not in use.

[0046] like Figure 2 As shown, the inner wall of the mask base 1 is fixedly connected with a water-repellent film 28, and the water-repellent film 28 is transparent. The water-repellent film 28 fixedly connected to the inner wall of the mask base 1 can utilize the water-repellent effect of the water-repellent film 28 to avoid excessive condensation of liquid on the inner wall of the mask base 1, which causes liquid dripping and causes discomfort to the patient. At the same time, the water-repellent film 28 can make the liquid condensed on the inner wall of the mask base 1 flow along the water-repellent film 28 to the liquid storage tank 24, thereby timely removing the water vapor inside the mask base 1.

[0047] The working principle provided by the present invention is to scan the facial contour of the patient by using 3D printing technology, and then print out the mask base 1 and the base pad mechanism 2 that are personalized to the patient's facial contour by using the 3D printing device. The connecting ring seat 13 at the bottom end of the mask base 1 can be engaged through the plug-in groove 23 opened at the top of the mask base pad 14 to complete the connection and assembly between the mask base pad 14 and the mask base 1. When the entire anesthesia mask is used, the anesthesia gas delivery tube to be connected is first buckled on the surface of the ventilation tube 8 at the top of the mask base 1, and then the fastening nut 11 is rotated to fasten the nut. 11 moves along the thread on the surface of the expansion tube 9 to tighten the expansion tube 9, thereby clamping the anesthetic gas delivery tube so that it fits tightly against the ventilation tube 8 to complete the connection of the anesthetic gas delivery tube, and then buckles the anesthesia mask on the patient's face, applies slight pressure to the anesthesia mask, so that the base pad mechanism 2 fits tightly against the patient's face to meet the anesthetic gas supply conditions, and at the same time, according to actual use requirements, the straps used to fix the anesthesia mask are tied to the two sets of positioning rods 6 fixedly connected at the top of the mask base 1 near the expansion tube 9, so that medical staff can wear the anesthesia mask on the patient's head.

[0048] During the use of the entire anesthesia mask, water vapor generated inside the mask base 1 due to temperature changes during breathing will condense into liquid on the surface of the mask base 1. Under the water-repelling effect of the water-repelling membrane 28, the liquid slides along the water-repelling membrane 28 into the liquid storage tank 24 on the top of the connecting ring seat 13 for storage, thereby preventing the liquid from dripping onto the patient's face, causing discomfort to the patient, and preventing the patient from inhaling liquid and causing tracheal and lung infections. When a certain amount of liquid is accumulated in the liquid storage tank 24, the gas flowing during the patient's breathing process causes a slight pressure to be generated inside the mask base 1, and the liquid can be discharged through the liquid storage tank 24, the drainage groove 25 and the liquid through hole 26 into the pressing plate 16 groove body inside the expansion cavity 15, and then the liquid can be discharged into the expansion cavity 15 by the liquid storage tank 24. The inclined pressing piece 16 on the outer wall of the mask base pad 14 guides the liquid and discharges the liquid through the drainage hole 18 opened on the outer wall of the mask base pad 14. The V-shaped pressing piece 16 can guide and store the liquid inside, which further facilitates the centralized collection of the liquid and also increases the collection and storage capacity of the liquid. When a certain amount of liquid is stored inside the V-shaped pressing piece 16, the liquid is discharged into the liquid storage bag 20 through the drainage hose 19 by adjusting the flow regulator 21 installed on the outer wall of the drainage hose 19. When the liquid in the liquid storage bag 20 needs to be discharged, the flow regulator 21 can be used to intercept and close the drainage hose 19, thereby avoiding gas leakage in the mask when discharging the liquid in the liquid storage bag 20.

[0049] When the mask is in use, the expansion cavity 15 opened inside the mask base pad 14 facilitates the use of the expansion cavity 15 to improve the overall softness of the mask base pad 14, and then when the anesthesia mask is used, when the mask base pad 14 is compressed, it can better adapt to the patient's facial contour, so that it can fit the patient's face closely to avoid gas leakage. The pressing piece 16 fixedly connected to the top of the expansion cavity 15 facilitates the pressure applied to the top of the mask base pad 14 to be transmitted to the surface of the elastic piece 22 through the pressing piece 16, so as to use the elastic piece 22 to generate downward pressure on the entire anesthesia mask. The force distribution is carried out to improve the uniformity of the force at the bottom of the mask base pad 14. The downward pressure of the pressing plate 16 can be distributed through the filling strip 27 fixedly connected to the top of the elastic plate 22 away from one end of the pressing plate 16, so that the downward pressure is evenly distributed to the surface of the elastic plate 22, thereby avoiding uneven force on the mask base pad 14 and prone to excessive tilting, so that the mask base pad 14 cannot fit the patient's face tightly. At the same time, the pressing plate 16 with the two ends of the top located on both sides of the inner wall of the buckle groove 29 can generate a clamping force to improve the firmness between the connecting ring seat 13 and the plug-in groove 23.

[0050] The rubber soft plate 7 located at the top of the two groups of positioning rods 6 makes it convenient for the medical staff's palm to be supported when the medical staff grabs the connection between the anesthetic gas delivery tube and the ventilation tube 8 to apply pressure to the entire anesthesia mask, thereby improving the comfort of the medical staff in taking the anesthesia mask, and also allows the downward pressure generated by the medical staff pressing down the anesthesia mask to be evenly transmitted to the entire surface of the anesthesia mask. The extension rod 12 installed through the mounting hole on the surface of the rubber soft plate 7 can be used to induce anesthesia for child patients, and can be used to hang ornaments for soothing children's fear, thereby reducing the fear of children of the anesthesia mask, and the extension rod 12 installed by the buckle can be disassembled when not in use.
