Abstract
Description
[Technical Field]
[0001] This invention relates to the field of medical device technology, and in particular to a manufacturing process for an integrated non-invasive oxygen mask. [Background Technology]
[0002] In the field of medical devices, oxygen masks are widely used. For this purpose, the invention patent with announcement number CN102238976B discloses a shield for non-invasive ventilation of patients, including a receiving body, the receiving body having at least one light-transmitting portion and a collar, and the collar being sealably fitted to the patient's neck, with the patient's head being received in the shield. The shield also includes an annular body on which a pad is heat-sealed or fixed and can be associated around the neck and fixed to the receiving body. The annular body fixed to the receiving body is substantially rigid and adapted to be used together with the pad as an abutment for the collar.
[0003] The aforementioned invention patent has the following problems: the detachable connection between the pad and the receiving body results in many parts, high manufacturing costs, complicated assembly, poor patient experience, and a significantly reduced sealing of the receiving body due to the detachable connection between the parts. Furthermore, the pad is installed by relying on a ring body, and the size of the inner ring not only affects the user's wearing and removal but also affects the direction of the pad's expansion, greatly reducing the distance of the pad's expansion protrusion towards the user's neck. Consequently, the pad cannot seal the collar tightly against the patient's neck, resulting in insufficient sealing of the receiving body.
[0004] Therefore, existing technology cannot meet our needs. [Summary of the Invention]
[0005] To address the above problems, this invention provides a manufacturing process for an integrated non-invasive oxygen mask with high manufacturing efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0015] S8, manufacture a barrel-shaped side circumference by welding the two ends of the oxygen mask side circumference sheet together, so that the oxygen mask side circumference sheet forms a hollow barrel-shaped side circumference. The neck is located inside the barrel-shaped side circumference, so that several connecting parts and several extrusion spaces are distributed in a ring shape inside the barrel-shaped side circumference.
[0016] S9, Welding the leak-proof barrier sheet: Weld the two ends of the leak-proof barrier sheet together along its length and weld it to the upper end of the neck warmer or the side panel of the oxygen mask and above the inner wall surface of the upper end of the neck warmer.
[0017] S10, making a receiving body for accommodating the patient's head: the top layer sheet of the oxygen mask is fused to the end of the side sheet of the oxygen mask away from the neck, so that the top layer sheet of the oxygen mask and the side sheet of the oxygen mask form a hollow receiving body for accommodating the patient's head.
[0018] S11, Equipped with an inflation / deflation device: A device for inflating and deflating the neck warmer is connected to the neck warmer's air nozzle, thereby adjusting the size of the airbag protrusion and the compression space.
[0019] As a preferred embodiment, the method is further defined as follows: the method includes the following step between step S3 and S4:
[0020] Assemble the shoulder straps: Fix several Velcro straps to the outer circumferential surface of the oxygen mask side panel, and attach the two ends of the shoulder straps to the two Velcro straps respectively.
[0021] As a preferred embodiment, it is further defined as follows: the shoulder strap is divided into a first straight section, an arc section and a second straight section along its length direction. When the first straight section and the second straight section are respectively connected to the Velcro, the shoulder strap is U-shaped after connection and the shoulder strap is tilted, so that the arc length of the side line located on the lower side of the arc section is greater than the arc length of the side line on the upper side, thereby making the arc section fan-shaped.
[0022] As a preferred embodiment, it is further defined as follows: in step S4, the injection molding machine forms one or more rows of air bladder protrusions and air bladder grooves from the flat third raw material through vacuum forming, and a connecting part is also provided between the bottoms of two rows of adjacent air bladder protrusions so that a compression space is formed between the two rows of adjacent air bladder protrusions.
[0023] As a preferred embodiment, the device is further defined as follows: the inflation / deflation device includes an air tube, an inflation bladder for inflating the air bladder cavity, and a regulating valve body disposed between the air tube and the inflation bladder for releasing gas from the air bladder cavity; one end of the air tube is sealed to the neck warmer nozzle, and the other end of the air tube is sealed to the regulating valve body.
[0024] As a preferred embodiment, it is further defined that: the first raw material, the second raw material and the third raw material are all made of TPU, wherein the TPU is thermoplastic polyurethane elastomer rubber.
[0025] As a preferred embodiment, the gas connector includes a first plastic nozzle and a second plastic nozzle formed by injection molding. The first plastic nozzle is used to supply gas to the container body, and the second plastic nozzle is used to discharge gas from the container body. A metal nozzle is also fitted onto the second plastic nozzle.
[0026] As a preferred embodiment, the gas connector is further defined as follows: the gas connector is made of TPU particles by injection molding.
[0027] As a preferred embodiment, it is further defined as follows: the leak-proof barrier sheet includes a leak-proof barrier sheet body and a skirt that is disposed on the upper end of the leak-proof barrier sheet body and expands outward to form a disc. The skirt can fit against the upper surface of the neck warmer. The end of the skirt away from the leak-proof barrier sheet body is connected to the inner wall surface of the oxygen mask side panel. The leak-proof barrier sheet body can fit against the protrusion of the airbag. The leak-proof barrier sheet body extends out of the opening of the receiving body along its axial direction, so that one side of the leak-proof barrier sheet fits against the patient's neck, and the other side of the leak-proof barrier sheet covers the connecting part and the compression space.
[0028] As a preferred embodiment, it is further defined as follows: the air-proof barrier sheet is also provided with a rope strip for fixing and surrounding the outer periphery of the air-proof barrier sheet, a rope wrapped inside the rope strip, and a press-type rope buckle for the two ends of the rope to pass through.
[0029] The beneficial effects of this invention are: This invention is simple and quick to manufacture, low in cost, and highly efficient. Once manufactured, it is assembled as a single unit, eliminating the need for patient self-assembly. Patients can simply remove it and put it on immediately when needed. Furthermore, the top layer of the oxygen mask, the side panels of the oxygen mask, the neck warmer, and the leak-proof barrier are all integrally connected, greatly improving the airtightness of the oxygen mask. The neck warmer requires no installation; when the patient manually presses the regulating valve to release the gas inside the neck warmer, it shrinks, allowing the patient to quickly remove the oxygen mask. Because the neck warmer is in a shrunken state, it can be easily fitted regardless of the patient's head circumference. When the patient manually presses the inflation bladder to inflate the neck warmer, each bladder protrusion expands and bulges inward, causing the leak-proof barrier to fit tightly against the patient's neck, thus creating a sealed space inside the oxygen mask. This provides excellent airtightness and makes wearing and removing the mask simple and quick. [Attached Image Description]

Detailed Implementation Methods
[0051] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0052] As attached Figure 1 To be continued Figure 21 As shown, a manufacturing process for an integrated non-invasive oxygen mask includes the following steps:
[0053] S1, cut the first raw material 11 and the second raw material 12 required for manufacturing the oxygen mask: select the first raw material 11 and the second raw material 12. The first raw material 11 is a transparent plastic sheet or a transparent rubber sheet, and the second raw material 12 is a flexible sealing material. Cut the first raw material 11 into the top layer sheet 1 of the oxygen mask, the side sheet 2 of the oxygen mask, and the bottom sheet 3 of the neck warmer. Cut the second raw material 12 into the leak-proof barrier sheet 4.
[0054] S2, opening air inlets and outlets: several air inlets 21 and air outlets 22 are opened on the side sheet 2 of the oxygen mask.
[0055] S3, Assemble and fix the gas connector 6: Insert the gas connector 6 into the side air inlet 21 and the side air outlet 22, and weld the gas connector 6 to the oxygen mask side sheet 2.
[0056] S4, Manufacturing scarf fabric 50: Select a third raw material 501, which is a plastic sheet or a rubber sheet. Place the third raw material 501 on a vacuum forming machine. The vacuum forming machine forms the flat third raw material 501 into a raised airbag protrusion 56 with several spaced intervals on one side and a corresponding airbag groove 51 on the other side. A connecting part 57 is provided between the bottoms of two adjacent airbag protrusions 56 so that a compression space 58 is formed between the two adjacent airbag protrusions 56.
[0057] S5, Manufacturing the scarf 5: The scarf base 3 and the scarf fabric 50 are welded together on one side of the airbag groove 51 by a welding machine, so that all the airbag grooves 51 are connected and form an airbag cavity.
[0058] S6, Welding neck air nozzle 52: Make a neck air nozzle hole on the neck 5, pass the neck air nozzle 52 through the neck air nozzle hole, and use a welding machine to weld the neck air nozzle 52 onto the neck 5.
[0059] S7, Integrated fixed neck warmer 5: The neck warmer bottom piece 3 of the neck warmer 5 is fused to the lower end of the oxygen mask side panel 2, so that the connecting part 57 and the compression space 58 face away from the oxygen mask side panel 2.
[0060] S8, manufacture a barrel-shaped side circumference by welding the two ends of the oxygen mask side circumference sheet 2 together, so that the oxygen mask side circumference sheet 2 forms a hollow barrel-shaped side circumference. The neck circumference 5 is located inside the barrel-shaped side circumference, so that a number of connecting parts 57 and a number of compression spaces 58 are distributed in a ring shape inside the barrel-shaped side circumference.
[0061] S9, Welding the leak-proof barrier sheet 4: Weld the two ends of the leak-proof barrier sheet 4 together along its length and weld it to the upper end of the neck warmer 5 or the oxygen mask side panel sheet 2 and above the inner wall surface of the upper end of the neck warmer 5.
[0062] S10, making a receiving body for accommodating the patient's head: the top layer sheet 1 of the oxygen mask is fused to the end of the side sheet 2 of the oxygen mask away from the neck 5, so that the top layer sheet 1 of the oxygen mask and the side sheet 2 of the oxygen mask form a hollow receiving body 100 for accommodating the patient's head.
[0063] S11, Attach an inflation / deflation device: Connect a device for inflating / deflating the neck warmer 5 to the neck warmer nozzle 52, thereby adjusting the size of the airbag protrusion 56 and the compression space 58.
[0064] Furthermore, in step S6, the neck warmer nozzle 52 can be fused to the neck warmer base plate 3 or to the airbag protrusion 56 of the neck warmer fabric 50. In this embodiment, the neck warmer nozzle 52 is fused to the neck warmer base plate 3, and the neck warmer nozzle 52 also protrudes through the oxygen mask side panel 2. The neck warmer nozzle 52 is also fused together with the oxygen mask side panel 2, which facilitates the assembly of the inflation / deflation device. Of course, the neck warmer nozzle 52 can also be located at the lower end of the airbag protrusion 56, so that the neck warmer nozzle 52 is not blocked by the oxygen mask side panel 2 and is directly exposed. The inflation / deflation device can be directly assembled. This technical solution is a replacement for step S6 and is also included in the protection scope of this invention.
[0065] Furthermore, in step S7, the neck warmer bottom piece 3 of the neck warmer 5 is connected to the side of the oxygen mask side panel 2 opposite to the side connected to the gas connector 6. The neck warmer 5 and the left and right ends and the bottom end of the oxygen mask side panel 2 are aligned. Of course, it can also be set so that the bottom ends are not aligned. This technical solution is a replacement for step S7 and is also included in the protection scope of this invention.
[0066] Furthermore, in step S9, the upper end of the leak-proof barrier sheet 4 is welded to the outer periphery of the neck warmer 5 or the inner wall of the oxygen mask side panel sheet 2 using a welding machine. The welding machine is a high-frequency plastic welding machine or an ultrasonic welding machine. The welding and welding of the welding machine makes the connection tight, and there are no gaps between the neck warmer 5 and the oxygen mask side panel sheet 2, avoiding air leakage. This ensures that the oxygen mask side panel sheet 2 can only communicate with the outside world through the space formed by the leak-proof barrier sheet 4, and cannot communicate with the outside world through the neck warmer 5 or the oxygen mask side panel sheet 2, thus improving the airtightness of the housing body 100 and effectively protecting the patient's personal safety.
[0067] Furthermore, not only can the leak-proof barrier sheet 4 be welded using step S9, but the following welding and assembly method can also be used: after fixing the neck warmer 5 in step S7, the leak-proof barrier sheet 4 is directly fused to the upper end of the neck warmer 5 or the oxygen mask side panel sheet 2 and is higher than the inner wall surface of the upper end of the neck warmer 5. This allows the leak-proof barrier sheet 4 to be fused together at both ends along its length in step S8, and then the left and right ends of the oxygen mask side panel sheet 2 to be fused together. This technical solution is a replacement for step S8 and is also included in the protection scope of this invention.
[0068] As attached Figure 1 To be continued Figure 6 and attached Figure 19 As shown, in this embodiment, the following steps are also included between steps S3 and S4: assembling the shoulder strap 8: fixing several Velcro straps 7 on the outer peripheral surface of the oxygen mask side panel 2, and attaching the two ends of the shoulder strap 8 to the two Velcro straps 7 respectively.
[0069] This invention is simple, quick, low-cost, and highly efficient to manufacture. Once manufactured, it is assembled as a single unit, eliminating the need for patient assembly. Patients can simply remove it and put it on immediately when needed. Furthermore, the top layer of the oxygen mask (1), the side panels (2), the neck warmer (5), and the leak-proof barrier (4) are integrated into a single unit, significantly improving the airtightness of the oxygen mask. The neck warmer (5) requires no additional installation; when the patient manually presses the regulating valve (55) to release the gas within the neck warmer (5), the airbag protrusion (56) shrinks, and the compression space (58) expands. The patient can quickly remove the oxygen mask, and because the neck warmer 5 is in a reduced state when put on, it can be easily slipped on regardless of the patient's head circumference. When the patient manually presses the inflatable bladder 54 to inflate the neck warmer 5, the bladder protrusion 56 enlarges, the compression space 58 shrinks, and each bladder protrusion 56 expands and bulges inward, so that the bladder protrusion 56 presses the leak-proof barrier sheet 4 tightly against the patient's neck, thereby forming a sealed space within the housing 100. It has good sealing performance and is simple and quick to put on and take off.
[0070] As attached Figure 9 To be continued Figure 19 As shown, in this embodiment, the shoulder strap 8 is divided into a first straight section 81, an arc section 82, and a second straight section 83 along its length. When the first straight section 81 and the second straight section 83 are connected to the Velcro 7, the shoulder strap 8 is U-shaped and tilted after connection, so that the arc length of the lower side of the arc section 82 is greater than the arc length of the upper side, thus making the arc section 82 fan-shaped.
[0071] Furthermore, the Velcro 7 is made of TPU injection molding, and the shoulder strap 8 is made of TPU injection molding or cloth. Both ends of the shoulder strap 8 are attached to the outer peripheral surface of the receiving body via Velcro 7, that is, fixedly connected to the outer peripheral surface of the oxygen mask side panel 2, allowing for quick assembly and disassembly. The shoulder strap 8 is an optional feature, and it is included with the product. It can be assembled together with the oxygen mask after manufacturing, or the manufactured shoulder strap 8 can be placed together with the oxygen mask in the packaging box. Patients can choose to use it with or without the shoulder strap depending on their actual situation. Using it with the shoulder strap can prevent the receiving body from moving axially, prevent the oxygen mask from falling off, and ensure the safety of the patient. In addition, the fan-shaped design of the shoulder strap 8 conforms to ergonomic design, thereby increasing the comfort of the patient when wearing it.
[0072] As attached Figure 14 To be continued Figure 15 As shown, in this embodiment, in step S4, the injection molding machine forms one or more rows of airbag protrusions 56 and airbag grooves 51 from the flat third raw material 501 through vacuum forming. A connecting part 57 is also provided between the bottoms of two rows of adjacent airbag protrusions 56 so that a compression space 58 is formed between the two rows of adjacent airbag protrusions 56.
[0073] Furthermore, when each scarf 5 is manufactured individually, only one row of air bladder protrusions 56 and air bladder grooves 51 need to be vacuum-formed from the third material 501. When multiple scarves 5 are manufactured together, only one row of air bladder protrusions 56 and air bladder grooves 51 need to be vacuum-formed from the third material 501. When multiple scarves 5 are manufactured together, after manufacturing the scarf 5 in step S5 or after welding the scarf air nozzle 52 in step S6, the composite of the manufactured scarves 5 needs to be cut to form several individual scarves 5, and one of the scarves 5 is used for fixing in step S7. In this embodiment, steps S3 to S6 involve manufacturing several scarves 5 together. Manufacturing several scarves 5 together can quickly achieve mass production, reduce production costs, save human resources, improve production efficiency, and provide timely material supply for step S7, ensuring normal and continuous production.
[0074] Furthermore, as shown in the attached document Figure 14 The neck warmer 5 can be configured to have a row of air bladder protrusions 56 and air bladder recesses 51; as shown in the attached figure. Figure 15 The neck warmer 5 can also be configured to have multiple rows of airbag protrusions 56 and airbag grooves 51. When cutting, it is only necessary to cut the composite of multiple neck warmers 5 into the desired neck warmer with one or more rows of airbag protrusions 56 and airbag grooves 51. The product is highly adaptable. The neck warmer 5 has multiple rows of airbag protrusions 56 and airbag grooves 51, which enhances the compression effect on the anti-leakage barrier sheet 4 and further enhances the airtightness of the housing body 100.
[0075] As attached Figure 4 To be continued Figure 6 and attached Figure 18 To be continued Figure 19 As shown, in this embodiment, the inflation / deflation device includes an air tube 53, an inflation bladder 54 for inflating the airbag cavity, and a regulating valve 55 disposed between the air tube 53 and the inflation bladder 54 for releasing gas from the airbag cavity. One end of the air tube 53 is sealed to the neck warmer nozzle 52, and the other end of the air tube 53 is sealed to the regulating valve 55. When the user manually presses the regulating valve 55 to release the gas from the neck warmer 5, the airbag protrusion 56 shrinks, allowing the user to quickly remove the containing body. Furthermore, because the neck warmer 5 is in a shrunken state when worn, it can be easily slipped on regardless of head circumference. When the user manually presses the inflatable bladder 42 to inflate the neck warmer 5, each bladder groove 51 expands and bulges inward, causing the bladder protrusion 56 to press the leak-proof barrier sheet 4 tightly against the user's neck, thus forming a sealed space within the enclosure. This provides excellent sealing, making it easy and quick to put on and take off, ensuring the oxygen mask is safe and hygienic. The adjusting valve 55 has a simple structure and ingenious design, resulting in high deflation efficiency. This facilitates timely putting on and taking off by doctors or patients, effectively protecting the patient's safety. Furthermore, the adjusting valve 55 and the inflatable bladder 54 are manually pressable, allowing the patient to adjust the tightness of the neck warmer 5 according to their needs, ensuring comfortable wear.
[0076] As attached Figure 19 As shown, in this embodiment, the first raw material 11, the second raw material 12, and the third raw material 501 are all made of TPU, which is thermoplastic polyurethane elastomer rubber. The TPU material makes the top layer sheet 1 of the oxygen mask and the side sheet 2 of the oxygen mask transparent, allowing doctors and family members to observe the patient's condition in a timely manner, and the patient can also see the outside world clearly. In addition, the TPU material is soft and skin-friendly, comfortable to contact with the patient's skin without adverse effects, hygienic and safe, and protects the patient's safety.
[0077] As attached Figure 2 To be continued Figure 9 As shown, in this embodiment, the gas connector 6 includes a first plastic nozzle 61 and a second plastic nozzle 62 formed by injection molding. The first plastic nozzle 61 is used to supply gas to the container body, and the second plastic nozzle 62 is used to discharge gas from the container body. A metal nozzle 63 is also fitted onto the second plastic nozzle 62. The gas connector 6 is made of TPU particles by injection molding. The gas connector is made of TPU material, which is hygienic and safe. The metal nozzle 63 is also fitted onto the second plastic nozzle 62, which facilitates quick and easy disassembly and connection of the oxygen tube, thereby preventing damage to the second plastic nozzle 62 caused by frequent disassembly and assembly.
[0078] As attached Figure 2 To be continued Figure 6 and attached Figure 17 To be continued Figure 21 As shown, in this embodiment, the leak-proof barrier sheet 4 includes a leak-proof barrier sheet body 41 and a skirt 42 disposed on the upper end of the leak-proof barrier sheet body 41 and expanding outward to form a disc. The skirt 42 can fit against the upper surface of the neck warmer 5, and the end of the skirt 42 away from the leak-proof barrier sheet body 41 is connected to the inner wall surface of the oxygen mask side panel 2. The leak-proof barrier sheet body 41 can fit against the airbag protrusion 56. The leak-proof barrier sheet body 41 extends outward along its axial direction. The opening of the housing body allows one side of the leak-proof barrier sheet 4 to fit against the patient's neck, while the other side of the leak-proof barrier sheet 4 covers the connecting part 57 and the compression space 58. This ensures that there are no gaps between the neck warmer 5 and the oxygen mask side panel 2, preventing air leakage. As a result, the oxygen mask side panel 2 can only communicate with the outside world through the space formed by the leak-proof barrier sheet 4, and cannot communicate with the outside world through the neck warmer 5 or the oxygen mask side panel 2. This improves the airtightness of the housing body 100 and effectively protects the patient's personal safety.
[0079] As attached Figure 2 To be continued Figure 6 and attached Figure 17 To be continued Figure 21 As shown, in this embodiment, the air-proof barrier sheet 4 is further provided with a rope strip 43 for fixing and surrounding the outer periphery of the air-proof barrier sheet 4, a rope 44 wrapped inside the rope strip 43, and a press-type rope buckle 45 for the two ends of the rope 44 to pass through.
[0080] Furthermore, the skirt hem 42 can fit against the upper surface of the neck warmer 5, and the end of the skirt hem 42 away from the leak-proof barrier sheet body 41 is connected to the inner wall surface of the oxygen mask side panel 2. The leak-proof barrier sheet body 41 can fit against the airbag protrusion 56. The leak-proof barrier sheet body 41 extends out of the opening of the receiving body along its axial direction. In use, each airbag protrusion 56 expands and protrudes towards each other, thus... The leak-proof barrier sheet body 41 fits snugly against the patient's neck and can also protrude upwards to fit the skirt 42 snugly against the patient's chin or lower face. During use, the rope 44 is stretched to the appropriate length by manually pressing the snap-on buckle 45. After releasing, the snap-on buckle 45 locks the rope 44 to the appropriate length. The operation is simple and convenient for users. The rope 44 further snugs the leak-proof barrier sheet body 41 against the patient's neck, further increasing the airtightness of the oxygen mask.
