Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a 3D-printed personalized anesthesia mask. BACKGROUND

[0002] Anesthesia induction is the first stage of general anesthesia, which is the process of using anesthetic drugs, including sedatives, analgesics, intravenous or inhaled anesthetics, and muscle relaxants, to convert patients from a conscious state to an anesthetized state for surgical operation. During the inhaled anesthesia induction process, an anesthesia mask is needed to assist in the completion. During the anesthesia process, the anesthesia mask is an important device for delivering anesthetic gas or oxygen to the patient.

[0003] Traditional anesthesia masks are usually of standard size, although they can meet the basic requirements of sealing in terms of function, they often cannot provide the best comfort and sealing for each 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, and the condensed water vapor is easy to flow to the patient's face and mouth, causing the patient to be uncomfortable and also easy to be inhaled into the respiratory tract, causing safety hazards. At the same time, due to different ways of pressing the mask, the force of the bottom end 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 anesthesia mask to meet the needs. SUMMARY

By fixing the liquid discharge hose 19 to the outer side wall of the mask bottom pad 14, the liquid discharged from the liquid discharge hole 18 can be discharged into the liquid storage bag 20 through the liquid discharge hose 19, and the flow regulator 21 detachably installed on the outer wall of the liquid discharge hose 19 facilitates the flow regulation of the liquid discharge hose 19 by the flow regulator 21, so as to discharge 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 cut off the flow of the liquid discharge hose 19, so as to avoid the leakage of gas in the mask when the liquid in the liquid storage bag 20 is discharged.

[0045] As shown in Figure 1 and Figure 3As shown, the fixing mechanism 4 includes two groups of positioning rods 6 fixedly connected to the top end of the mask base body 1, and the two groups of positioning rods 6 are located on both sides of the inflation pipe 9, and the top end of each of the two groups of positioning rods 6 is fixedly connected with a rubber soft plate 7, and the top of the rubber soft plate 7 is provided with an extension rod 12 through the installation hole plug buckle, and through the arrangement of the two groups of positioning rods 6, the binding belt for fixing the whole anesthesia mask is conveniently bound, so that the medical staff can wear the anesthesia mask on the head of the patient, and the rubber soft plate 7 located at the top end of the two groups of positioning rods 6 can conveniently support the palm of the medical staff when the medical staff grab the connection between the anesthesia gas delivery pipe and the ventilation pipe 8, and thus the comfort degree of the medical staff in taking the anesthesia mask is improved, and the downward pressure generated by the medical staff in pressing the anesthesia mask can be uniformly transmitted to the surface of the whole anesthesia mask, and the extension rod 12 installed on the surface of the rubber soft plate 7 through the installation hole plug buckle can be used to hook the pendant for comforting the fear of children when the child patient is induced anesthesia, so as to reduce the fear of the child patient to the anesthesia mask, and the plug-buckled extension rod 12 can be detached when not in use.

[0046] As shown in the figure, Figure 2 As shown, the inner wall of the mask base body 1 is fixedly connected with a water-repellent film 28, and the water-repellent film 28 is transparent, and through the water-repellent film 28 fixedly connected with the inner wall of the mask base body 1, the water-repellent effect of the water-repellent film 28 can be utilized to avoid the condensation of too much liquid on the inner wall of the mask base body 1, so that the patient is not uncomfortable due to the liquid drop caused by the condensation of too much liquid on the inner wall of the mask base body 1, and the water-repellent film 28 can make the liquid condensed on the inner wall of the mask base body 1 flow along the water-repellent film 28 to the liquid storage groove 24, so as to timely remove the water vapor inside the mask base body 1.

[0047] The working principle provided by the present application utilizes the 3D printing technology to scan the face contour of the patient, and then prints the mask base body 1 and the bottom pad mechanism 2 which are personalized according to the face contour of the patient through the 3D printing equipment, the extension rod 12 is installed on the surface of the rubber soft plate 7 through the installation hole plug buckle, the extension rod 12 can be used to hook the pendant for comforting the fear of children when the child patient is induced anesthesia, so as to reduce the fear of the child patient to the anesthesia mask, and the plug-buckled extension rod 12 can be detached when not in use.

[0048] The whole anesthesia mask, during use, the water vapor generated in the mask base body 1 due to temperature difference change during breathing can condense into liquid on the surface of the mask base body 1, and the liquid is affected by gravity under the water removal effect of the water removal film 28 and slides into the liquid storage tank 24 at the top of the adapter ring seat 13 for storage, thereby avoiding liquid drops to the patient's face, causing discomfort to the patient and avoiding the patient inhaling liquid causing tracheal and lung infection. When a certain amount of liquid is accumulated in the liquid storage tank 24, the gas flowing during the patient's breathing can cause a slight pressure in the mask base body 1, which can discharge the liquid from the liquid storage tank 24 into the pressure plate 16 groove in the expansion cavity 15 through the liquid discharge groove 25 and the liquid passage hole 26. The liquid is guided by the pressure plate 16 inclined to the outside of the mask bottom pad 14, and the liquid is discharged through the liquid discharge hole 18 opened in the outer wall of the mask bottom pad 14. The V-shaped pressure plate 16 can guide and store liquid, further facilitating the collection of liquid, and also increasing the storage capacity of the liquid. When a certain amount of liquid is stored in the V-shaped pressure plate 16, the flow regulator 21 installed on the outer sleeve buckle of the liquid discharge hose 19 is adjusted, and the liquid is discharged into the liquid storage bag 20 through the liquid discharge hose 19. When it is necessary to discharge the liquid in the liquid storage bag 20, the flow regulator 21 can be used to close the liquid discharge hose 19, thereby avoiding the leakage of gas in the mask when discharging the liquid in the liquid storage bag 20.

[0049] When the mask is used, the expansion cavity 15 opened in the mask bottom pad 14 facilitates the use of the expansion cavity 15 to improve the overall softness of the mask bottom pad 14, and the pressure plate 16 fixedly connected to the top end of the expansion cavity 15 can be used to transmit the pressure applied to the top end of the mask bottom pad 14 to the surface of the elastic sheet 22 through the pressure plate 16, thereby guiding the downward pressure generated by the whole anesthesia mask to the surface of the elastic sheet 22, improving the uniformity of the stress on the bottom of the mask bottom pad 14. The pressure plate 16 can be guided by the pressure plate 16, so that the downward pressure is uniformly guided to the surface of the elastic sheet 22, avoiding uneven stress on the mask bottom pad 14, which can cause excessive lateral inclination, thereby preventing the mask bottom pad 14 from closely fitting the patient's face. At the same time, the pressure plate 16 at the top of the two ends is located in the two sides of the insertion slot 29, which can generate clamping force and improve the firmness between the adapter ring seat 13 and the insertion slot 23.

[0050] The rubber soft plate 7 at the top of the two groups of positioning rods 6 facilitates the palm of the medical staff to be placed when the medical staff presses the whole anesthesia mask at the connection between the anesthesia gas delivery pipe and the ventilation pipe 8, thereby improving the comfort of the medical staff to take the anesthesia mask, and the downward pressure generated by the medical staff pressing the anesthesia mask can be uniformly transmitted to the surface of the whole anesthesia mask. The extension rod 12 installed on the surface of the rubber soft plate 7 through the mounting hole buckle can be used to hook the pendant for comforting the fear of children when the child patient is induced anesthesia, so as to reduce the fear of the child patient to the anesthesia mask, and the extension rod 12 installed by the buckle can be detached when not in use.
