Abstract
Description
Technical Field
[0001] This invention relates to the field of air reservoir manufacturing technology, and more specifically, to an anesthesia air reservoir and its manufacturing apparatus and method. Background Technology
[0002] Anesthesia reservoirs are typically made of materials such as silicone rubber, natural rubber, and natural latex. They consist of a reservoir and connectors and are used to store gas in the respiratory system of anesthesia machines to regulate the gas supply. Commonly used anesthesia reservoirs are spindle-shaped, with a larger middle and smaller ends. One end has a tail and the other end is open, connecting to a standard interface.
[0003] The production method of air reservoirs generally involves immersing a mold into a mixed emulsion to form a film, which is then vulcanized to obtain the air reservoir. Since the air reservoir is produced by directly bonding it to the mold, and the mold is narrow at the top and wide at the bottom, manual demolding is required. This results in low demolding efficiency, and people need to walk under the mold, which is inconvenient.
[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an anesthesia reservoir bag and its production device and method, which has the advantage of easy demolding.

The first substrate is made of silicone rubber or fluorinated rubber, and nano-silica hydrophobic modified particles are dispersed in the first substrate. The outer layer is a gas barrier layer, and the gas barrier layer includes a second substrate, which is made of natural latex or chloroprene latex. The gas barrier layer is coated with a halogenated butyl rubber barrier layer on the outside, and the hydrophobic interface layer and the gas barrier layer are chemically bonded together by co-vulcanization or an interface crosslinking agent.
[0007] An apparatus for producing an anesthesia reservoir, comprising: A frame, wherein a conveyor belt is provided on the top surface of the frame; The mold is set on the conveyor belt, and its surface configuration matches the shape of the capsule, including two sets of concave curved surfaces symmetrically arranged along the long axis and two sets of convex arc surfaces symmetrically arranged along the short axis. The impregnation tank is provided with several tanks, which are respectively used to carry the first mixed latex that forms the hydrophobic interface layer and the second mixed latex that forms the gas barrier layer; The vulcanization drying tunnel enables the formation of chemical bonds between the inner and outer layers of the capsule. The water spray demolding mechanism is mounted on a frame and includes two centrally symmetrical spraying units and a drive structure for controlling the movement of the spraying units within the frame. Each spraying unit includes several first nozzles and second nozzles. The first nozzles face the concave curved surface, and the second nozzles face the convex arc surface. The first nozzles and the second nozzles form an acute angle with the concave curved surface and the convex arc surface, respectively. The two spraying units and the first and second nozzles perform asymmetrical scouring on the mold surface, that is, the flow rate and velocity of the first nozzles and the second nozzles are inconsistent. A temperature controller is located on the side of the frame and is connected to the injection unit; The collection mechanism, located below the frame, is used to collect the water from the capsules and the spray, and to separate the capsules from the water.
[0008] The present invention is further configured such that the temperature controller includes: The low-temperature circuit supplies 20-30℃ cooling water to the second nozzle; The high-temperature circuit supplies 40-50℃ hot water to the first nozzle; The present invention is further configured such that: the driving structure includes a horizontal plate and a lifting rail, the lifting rail is fixedly connected to the frame and located on the side of the conveyor belt, the horizontal plate is slidably connected to the lifting rail, and the lifting rail is driven by a motor.
[0009] The present invention is further configured such that: the collection mechanism includes a receiving groove and a filter frame, the receiving groove is inclined to one side of the filter frame, a wastewater treatment tank is provided below the filter frame, and a squeezing plate is slidably connected inside the filter frame.
[0010] The present invention is further configured such that the impregnation tank is slidably connected to the inside of the frame via a cylinder.
[0011] The present invention is further configured such that: a rapid cooling air curtain is provided at the outlet of the vulcanizing oven tunnel, so that the surface temperature of the mold is reduced to room temperature before entering the water spray demolding mechanism.
[0012] A method for manufacturing an anesthesia reservoir, characterized by comprising the following steps: S1. Mold pretreatment: Clean and preheat the mold; S2. Impregnating the hydrophobic interface layer: Immerse the mold in an impregnation tank containing the first mixed latex (silicone rubber or fluorinated rubber latex containing nano-silica hydrophobic modified particles) for 10-30 seconds. After removal, perform preliminary drying to form a hydrophobic interface layer precursor. S3, Pre-curing: The mold and hydrophobic interface layer precursor obtained in S2 are subjected to preliminary heat treatment at a temperature of 60-80℃ for 1-3 minutes, so that the hydrophobic layer is partially cross-linked but the surface still has a certain activity. S4. Impregnating the outer layer: Immerse the mold treated in S3 into an impregnation tank containing the second mixed latex (natural latex or neoprene latex) for 5-20 seconds. After removal, perform preliminary drying to form the outer layer precursor. Utilize the surface activity of the partially cross-linked hydrophobic layer formed in step S3 to achieve good interfacial bonding with the wet outer layer precursor. S5. Coating a halogenated butyl rubber barrier layer: A halogenated butyl rubber solution is uniformly coated on the surface of the wet outer layer precursor obtained in S4. The thickness of the wet film is controlled so that the thickness of the halogenated butyl rubber barrier layer after final drying and curing is 1-3 micrometers. S6. Co-curing molding: The coated mold is sent into the curing oven and cured at 100-130℃ for 15-30 minutes, so that the hydrophobic interface layer, outer layer and barrier layer can be cross-linked and cured simultaneously, and a chemical bond is formed between the hydrophobic interface layer and the outer layer. S7. Water-cooled demolding: S7.1 Start the water spray demolding mechanism and set the water temperature of each first nozzle and second nozzle using the temperature controller; S7.2 Initial demolding section: Set the water temperature to 40-50℃, increase the spray flow rate and / or pressure of the first nozzle, and adjust the spray head angle to focus on rinsing the groove area. Utilize the softening effect of warm water and directional rinsing force to achieve non-destructive peeling of the bladder in the groove. S7.3 In the subsequent demolding section, the water temperature of the second nozzle is set to 20-30℃, the spray flow rate is less than that of the first nozzle, and the spray head angle is mainly aimed at the flat area of the mold body for cooling and initial peeling. S7.4. Based on the mold position and demolding status, adjust the position of the corresponding spray structure through motor drive to optimize the rinsing effect; S8. Collection and post-processing: After demolding, the capsules fall into the collection mechanism, where moisture is separated and necessary cleaning, drying, and quality inspection are carried out.
[0013] In summary, the present invention has the following beneficial effects: The inner layer uses silicone rubber or fluorinated rubber as the first matrix. Its hydrophobicity can effectively prevent anesthetic gas from condensing in the capsule. The surface micro-protrusion structure formed by the nano-silica hydrophobic modified particles dispersed in it further reduces the interfacial contact area, reduces the adhesion between the capsule and the mold, makes the demolding process smoother, and improves production efficiency. The hydrophobic interface layer and the gas barrier layer are chemically bonded together by co-sulfurization or an interface crosslinking agent, which enhances the tightness of the interlayer bonding, avoids the problem of interlayer delamination during use, and significantly extends the service life of the airbag. Two centrally symmetrical spraying units form an asymmetrical scouring effect through the acute angle between the first and second nozzles. Combined with the high and low temperature circuit of the temperature controller, the high temperature water softens and directionally scours the groove area to achieve non-destructive peeling, while the low temperature water cools the flat area to assist in demolding. With the flexible adjustment of the spraying position by the drive structure, demolding can be completed efficiently while protecting the capsule from damage to the greatest extent.

[0016] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0019] An anesthetic reservoir, such as Figures 1-2 As shown, the device includes a capsule 1, which comprises an outer layer 101 and an inner layer 102. The inner layer 102 is a hydrophobic interface layer, which includes a first substrate. The first substrate is made of silicone rubber or fluorinated rubber. The silicone rubber or fluorinated rubber provides hydrophobicity to prevent anesthetic gas condensation during use. Nano-sized hydrophobic modified silica particles are dispersed within the first substrate. These nano-sized hydrophobic modified silica particles form a micro-protrusion structure on the surface, reducing the interfacial contact area and decreasing the adhesion between the capsule 1 and the mold 3. High demolding efficiency; the outer layer 101 is a gas barrier layer, which includes a second matrix. The second matrix is made of natural latex or chloroprene latex, providing elasticity and biocompatibility to the main body. A halogenated butyl rubber barrier layer is laminated on the outside of the gas barrier layer to form a molecular-level barrier network, reducing the permeability of anesthetic gases. The hydrophobic interface layer and the gas barrier layer are chemically bonded together through co-vulcanization or interface crosslinking agents, which improves the tightness of the connection between the inner layer 102 and the outer layer 101, avoids interlayer delamination, and extends the service life of the airbag.
[0020] An apparatus for producing an anesthesia reservoir, used to produce an anesthesia reservoir, such as... Figures 2-5 As shown, the machine includes a frame 2, a conveyor belt 201 on the top surface of the frame 2, a mold 3 on the conveyor belt 201, and the surface configuration of the mold 3 matches the shape of the capsule 1. It includes two sets of concave curved surfaces 301 symmetrically arranged along the long axis and two sets of convex arc surfaces 302 symmetrically arranged along the short axis, which ensures that the wall thickness of the capsule 1 after impregnation is uniform and reduces stress concentration points. When demolding, the capsule 1 at the concave curved surface 301 can be removed first, so that the capsule 1 can be suspended at the position of the concave curved surface 301, which facilitates the removal of the capsule 1.
[0021] Several impregnation tanks 4 are provided, which are used to hold the first mixed latex that forms the hydrophobic interface layer and the second mixed latex that forms the gas barrier layer. The impregnation tanks 4 are slidably connected to the inside of the frame 2 by a cylinder. The operator can flexibly select the impregnation tank 4 to be used according to the different performance requirements of the capsule 1 in actual production, and can accurately control the impregnation time of the mold 3 in the impregnation tank 4. In this way, the formation of each layer of the capsule 1 is accurately realized, ensuring the quality stability of the capsule 1, and also improving the flexibility and adaptability of production.
[0022] The vulcanizing oven 5 enables the formation of chemical bonds between the inner layer 102 and the outer layer 101 of the capsule 1, promoting interlayer chemical bonding. The outlet of the vulcanizing oven 5 is equipped with a rapid cooling air curtain 501, which reduces the surface temperature of the mold 3 to room temperature before entering the water spray demolding mechanism. This rapid cooling treatment can effectively prevent the capsule 1 from being affected by excessive heat aging, and also provides a suitable temperature window for subsequent water spray demolding, ensuring that the demolding process can proceed smoothly.
[0023] The water spray demolding mechanism is mounted on the frame 2 and includes two centrally symmetrical spraying units and a drive structure for controlling the movement of the spraying units within the frame 2. The spraying unit includes several first nozzles 601 and second nozzles 602. The first nozzles 601 face the concave curved surface 301, and the second nozzles 602 face the convex arc surface 302. The first nozzles 601 and the second nozzles 602 form an acute angle with the concave curved surface 301 and the convex arc surface 302, respectively, so that the two spraying units and the first nozzles 601 and the second nozzles 602 can perform asymmetrical scouring on the surface of the mold 3. That is, the flow rate and flow velocity of the first nozzles 601 and the second nozzles 602 are inconsistent. This asymmetrical scouring can apply different scouring forces according to the structural characteristics of different parts of the mold 3, thereby more effectively demolding the capsule 1 while avoiding damage to the capsule 1. The temperature controller 7 is located on the side of the frame 2 and is connected to the spraying unit. The temperature controller 7 includes a low-temperature circuit and a high-temperature circuit. The temperature controller 7 works in conjunction with the first nozzle 601 and the second nozzle 602. The high-temperature circuit supplies 40-50℃ hot water to the first nozzle 601 to soften the capsule 1, making it easier for the capsule 1 located at the concave curved surface 301 to deform and demold. After being softened, the capsule 1 can undergo elastic deformation after receiving a strong impact and is not easily damaged. Therefore, the first nozzle 601 with strong impact force is used to impact this area, so that the capsule 1 can be quickly demolded. The low-temperature circuit supplies 20-30℃ cooling water to the second nozzle 602 to cool the capsule 1 located at the convex arc surface 302 and make it more resilient. When impacted by the second nozzle 602, the capsule 1 is not easily deformed. The thermal difference contraction effect is used to assist in the overall demolding, making the capsule 1 easy to be impacted and dropped. By distinguishing the impact temperatures of the two locations, efficient water spray demolding can be achieved while ensuring the quality of the capsule 1.
[0024] The drive structure includes a horizontal plate 8 and a lifting rail 9. The lifting rail 9 is fixedly connected to the frame 2 and is located on the side of the conveyor belt 201. The horizontal plate 8 is slidably connected to the lifting rail 9. The lifting rail 9 is driven by a motor 10. The motor 10 can drive the horizontal plate 8 to move on the lifting rail 9, thereby adjusting the position of the spraying unit to adapt to the needs of the mold 3 in different positions and different demolding states, and optimize the flushing effect.
[0025] A collection mechanism, located below the frame 2, is used to receive the capsule 1 and the sprayed water, and to separate the capsule 1 from the water. The collection mechanism includes a receiving trough 11 and a filter frame 12. The receiving trough 11 is inclined towards the filter frame 12. A wastewater treatment tank is provided below the filter frame 12. A squeezing plate 13 is slidably connected inside the filter frame 12. This inclined design allows the capsule 1 and water to flow smoothly into the filter frame 12 under the action of gravity. The wastewater treatment tank below the filter frame 12 facilitates the centralized treatment of wastewater after spraying. The squeezing plate 13 is slidably connected inside the filter frame 12. By sliding the squeezing plate 13, the capsule 1 falling into the filter frame 12 can be squeezed, further separating the residual water in the capsule 1 and improving the efficiency of subsequent treatment.

Impregnating hydrophobic interface layer: Immerse mold 3 into impregnation tank 4 containing first mixed latex (silicone rubber or fluorinated rubber latex containing nano-silica hydrophobic modified particles), and control the impregnation time to 10-30 seconds. After taking it out, it is preliminarily dried to form a hydrophobic interface layer precursor. S3, Pre-curing: The mold 3 and the hydrophobic interface layer precursor obtained in S2 are subjected to preliminary heat treatment. The temperature is controlled at 60-80℃ and the time is 1-3 minutes, so that the hydrophobic layer is partially cross-linked but the surface still has a certain activity. S4, Impregnating the outer layer 101: The mold 3 treated in S3 is immersed in the impregnation tank 4 containing the second mixed latex (natural latex or neoprene latex) for 5-20 seconds. After removal, it is preliminarily dried to form the precursor of the outer layer 101. The surface activity of the partially cross-linked hydrophobic layer formed in step S3 is used to achieve good interfacial bonding with the wet outer layer 101 precursor. S5. Coating a halogenated butyl rubber barrier layer: A halogenated butyl rubber solution is uniformly coated on the surface of the wet outer layer 101 precursor obtained in S4. The thickness of the wet film is controlled so that the thickness of the halogenated butyl rubber barrier layer after final drying and curing is 1-3 micrometers. S6. Co-curing molding: The coated mold 3 is sent into the curing oven 5 and cured at 100-130℃ for 15-30 minutes, so that the hydrophobic interface layer, outer layer 101 and barrier layer are cross-linked and cured simultaneously, and a chemical bond is formed between the hydrophobic interface layer and the outer layer 101. S7. Water-cooled demolding: S7.1 Start the water spray demolding mechanism, and set the spray water temperature of each first nozzle 601 and second nozzle 602 using the temperature controller 7; S7.2 Initial demolding section: Set the water temperature to 40-50℃, increase the spray flow rate and / or pressure of the first nozzle 601, and adjust the spray head angle to focus on rinsing the groove area. Utilize the softening effect of warm water and directional rinsing force to achieve non-destructive peeling of the bladder 1 in the groove. S7.3 In the subsequent demolding section, the water temperature of the second nozzle 602 is set to 20-30℃, the spray flow rate is less than that of the first nozzle 601, and the spray head angle is mainly aimed at the flat area of the main body of the mold 3 for cooling and initial peeling. S7.4. Based on the position of mold 3 and the demolding state, adjust the position of the corresponding section of the spray structure by driving motor 10 to optimize the rinsing effect; S8. Collection and post-processing: After demolding, the capsule 1 falls into the collection mechanism, and after the moisture is separated, it is cleaned, dried and inspected as necessary.
