Description of the invention (1) Background of the invention 1. Scope of the invention The present invention relates to components of a beer suction circuit and in particular to components of an exhalation arm for a breathing circuit. 2. Summary of previous techniques In order to aid breathing in medical applications, a gas containing a high relative humidity is supplied and a gas containing a high relative humidity is supplied and returned through a relatively restricted size tube. Such high humidity often causes accumulation of condensation with the inside wall of the catheter. Previous techniques have attempted to reduce the adverse effects of such condensation by reducing the degree of condensation or setting a collection point on the conduit to vaporize the condensed liquid from the conduit. Condensation reduction is usually achieved by maintaining and increasing the temperature of the gas flow and / or the temperature of the duct wall to reduce the formation of condensation. SUMMARY OF THE INVENTION The object of the present invention is to provide a component, which is particularly applicable to the exhalation limbs of the respiratory circuit, which is at least partially improved over the aforementioned devices or provides useful options for the general public and medical professionals. According to a first characteristic aspect, the present invention includes a breathing circuit assembly including an air inlet, an air outlet, and a boundary gas channel between the air inlet and the air outlet. At least one area of the wall is configured to allow water vapor to pass through but not Made of materials that allow liquid water or breathing gas to pass. In still another characteristic aspect, the present invention includes a device for forming a breathing circuit catheter, comprising: a formed part on which a tubular wall can be deposited, and the deposited tubular wall is advanced in the advance direction in advance The total paper size deposited for the axis rotation applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ^ Read Now! ? ?

Description of Invention (2) The wall, the forward speed and the rotation speed together define a pitch. At least one film laying head deposits a film on the forming part. The width of the film combination deposited by the film laying head is wider than the pitch, so the adjacent turns of the film are laid. Overlaid to form overlapping joints, a bead laying head is used for the film laying head, each of the bead laying heads lays reinforcing beads on the overlapping joints, I an axis laying head, the axis laying head Fitted on and sleeved over the shaped part and carrying multiple wire feeders, each of which allows the wire to be pulled from the storage, and a rotator to rotate the axis at substantially the same speed as the expected speed of the tube Laying head. Materials that allow the passage of water vapor but not the passage of liquid water or breathing gas in the description are described as "breathable materials". Materials become breathable due to the combination of material composition and physical structure. Those skilled in the art of the present invention may make various changes to the structure and broadly-varying specific embodiments and applications of the present invention without departing from the scope of the present invention as defined in the attached patent application 1.

Description of the invention (5) The space between the-flow, when used, water vapor but non-liquid water is transmitted from the beer gas channel to the suction gas channel. Another useful component encompassed by the present invention is a catheter hub. The application of the present invention to a catheter hub is described with reference to FIG. 13. In addition, one or more longitudinal sections (lengths) of the guide are made of breathable material; or the isolation area of the duct wall is made of this material. However, the specific embodiment described here is preferable because it is obviously simple to manufacture and can be made linearly, through continuous stitching, gluing, or dazzling, and by common rubbing or winding on the formed part. • In view of the material cost, the wall of the preferred duct is made to a relatively thin thickness, so the wall film is not strong enough to support itself. Referring to Figures 2, 6, 9a to 9i, 7 and 8, the spiral or helical inner (or outer) stiffener or series of ring stiffeners can be placed outside (or inside) the tube to provide support. The helical, helical or loop-shaped support member may be made of, for example, a polymer plastic material such as a material for a catheter wall (rather than a breathable area material) 'or a metal wire support member such as a rolled steel wire. The catheter shown in Figure 2 can be selected by one of several methods. For example, the tube can be supplied in a continuous tube. Alternatively, it can be supplied in a band, which results in the catheter of Fig. 6. The film is supplied in the form of an extruded belt, and the film is spirally wound on the forming part....

Description of the invention (6) Another extruded plastic mold strip or tape formed on the duct of the formed part. The extra saddle has multiple effects and effects. The sheath layer 83 provides additional strength, reinforcement, and protection, for example, by selecting an appropriate material or by selecting an appropriate material thickness. The material is made of, or aspirable material, such as the basis of the inner duct wall, or it can be made of a less expensive non- 乂 permeable material. In this case, a series of holes or perforations 85 may be provided along the strip or band 84 to provide water vapor or an access for collecting condensed water. Holes or perforations # The holes 85 are preferably formed by piercing the holes of the belt 84 with a heating spear during the forming process. The plastic film shrinks away from the heated spear to produce a uniform and appropriately sized hole. The lip of the hole has a stack of material to provide reinforcement. The sheath 83 treatment provides reinforcement and protection of the inner duct, and also provides a barrier to the airflow on the inner duct to obtain an insulation effect. The insulation effect is larger where the sheath 83 penetrates without perforations 85. According to Figures 9a-9i, it is found that one of the difficulties in using breathable parts such as Simpates is its low elastic drop. In this way, under the action of longitudinal force, the Simpates film is easily stretched inelastically, resulting in loss of aesthetics and narrowing of the tube diameter. The multiple wall specific embodiments described with reference to FIG. 6 can slightly overcome this difficulty as a second layer Breathable material. In addition, in the form of perforation, the outer plastic film can be made of a plastic material with a higher elasticity and drop strength than that of Jiajia Spartas. Another structure can be used as the longitudinal reinforcement of the tube. The reinforcement is preferably provided in the form of an additional sheath with an open or screen structure. For example, the sheath may be provided by a plurality of parallel extruded polymer wires parallel to the catheter shaft, the plurality of extruded polymer wires are braided or arranged in a similar manner around the catheter with its substantially axial composition provided in its direction, or Formed or continuously formed line network.I I ---- I ^ III III I--II (¾ ^ ¾ ^ on the back; please fill in this page for items of interest) 9 Intellectual Property Bureau Employee Consumer Cooperatives Printing 513318 A7 ^ ~ _ V. Description of the Invention (7) Provided as a method of manufacturing a sheath in a manner similar to the method of forming a respirable wall. Such screen materials can be manufactured by forming individual polymer wire meshes that are non-woven or woven, or by expanding micro-perforated sheets to produce enlarged screens, or by other suitable methods. Some methods or methods can be performed while using a screen to form a sleeve, or just before forming a rhyme sleeve. A variety of other embodiments of reinforced sheaths, such as other catheters introduced into the sheath as previously described, illustrate the first figure. Two other forms of ㈣ are illustrated in Figures 7 and 8. These specific embodiments have a number of advantages and disadvantages. Referring to Fig. 9a, the catheter is made of a pressure-spreading tape 200 spirally wound around a formed part to form a breathable wall. The screen sheath 20 is made of a Xue mesh belt spirally wound around the outside of the breathable member 200. The overlapping edges of the screen mesh belt and the breathable membrane belt are overlapped, and the molten plastic beads 201 are laid along these edge edges. The molten beads preferably excite the thermal bonding of all four overlapping layers, including two " u * clJi and two polymer screens. It is important to understand that the polymer screen can be on the inside or outside of the breathable element. However, it is preferred that the inner surface of the catheter wall is smooth, so that the preferred mesh belt can be applied to the outside of the breathable membrane. It must be understood that each turn of the screen belt can be directly applied to each turn of the breathable membrane, so the edge of the adjacent turn overlaps the edge of the screen, and passes between the edges of each turn of the breathable membrane band. Alternative. It must also be understood that either or both of the breathable membrane bands and the screen bands can be formed simultaneously with the catheters formed from them; the screens and membranes can be joined to their parts by heat from the beads 201 in addition to bonding, or All contact surfaces. The reference figure 9b shows a catheter having the same structure as that of the breathable membrane 200, the screen 200, and the beads 201. In addition, another breathable piece 203 sheath can be applied to the outside of the catheter, and the edge adjacent to the turn 203 is pressed and joined to the outside of the bead 201. This paper size applies the Chinese National Standard (CNS) A4 specification (2) 0 X 297 (Mm) " —--f ^ ----------------- (τ is called ¾ ^ on the back; it matters and then fill out this page) 513318 A; B: Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperation print 5. Inventory Note (8). This provides additional thermal insulation while allowing dehumidification between the inner and outer walls. Referring to Figure 9c, the catheter of Figure 9a is shown with a breathable membrane wall 200, a sieve sheath 202, and beads 201. In the specific embodiment of FIG. 9c, a further breathable membrane sheath 204 is disposed on the screen sheath 202. The effect is to encapsulate the screen 202 'to provide an improved aesthetic appearance and a more acceptable exterior surface. The disadvantage of this narrowing is that the heat from the beads 201 needs to be heated and bonded to multiple layers. This type of construction requires additional local heating, thermal fusion films 2000, 202, and 204® adjacent to the overlapping edges of the turns. A modified example of the specific embodiment shown in FIG. 9c will be described with reference to FIG. 9d. In this specific embodiment, the outer breathable membrane 205 is inflated outward by the screen member 202. As shown in FIG. 9c, the outer breathable membrane 202 faces away from or engages the screen member 202. In Fig. 9d, the breathable membrane 205 is supported away from the lower members 200 and 202 by the inflatable band 211. This example can be regarded as a modification of Fig. 9b, in which the beads 201 are entirely disposed outside the catheter. The multiple layers adjacent to the edge cause the same forming difficulties as in the specific embodiment of FIG. 7 (:). Referring to FIG. 9e, a section of the catheter in which the screen sheath is arranged to be separated from the breathable membrane catheter 璧 200.

If the beer suction film and one or more layers of green ducts of the division network are formed at the same time, the #layer 2 () 7 and the joint can be joined across part or all of the contact area. This concrete example provides the forming advantages of Figure 9e and a structure with similar quality to Figure% e. Referring to Fig. 9g 'in a further embodiment, the additional breathable membrane is placed in the embodiment of Fig. 9f across the multiple beads 2 () 1 and the outside of the screen 2007. To assist in joining and further strengthening the mesh # 2, additional beads 209 may be provided outside the second breathable layer 208. Referring to FIG. 9h, another specific embodiment is shown. This example is a modified example of the specific embodiment shown in FIG. In the specific embodiment of FIG. 9h, the second breathable film layer 210 is disposed on the outside of the second bead 209. Instead of the specific embodiment shown in the figure, the second breathable layer 208 is provided between the second bead 209 and the screen layer 207. This provides a large enclosed air space between the breathable layers 202 and 210, and at any time only double the thickness of the polymer, film, or screen is required to join the beads 201 or 209. Fig. 9m of a tea photo shows still another specific embodiment. This example is a modified example of the specific embodiment of the first figure. In the specific embodiment of FIG. 9i, the screen layer 200 is not flattered, collapsed, or decompressed as shown in FIGS. 9f-9h, and the screen layer 206 is in the manner of FIG. between. In this way, a pair of air spaces are provided between the breathable layers 200 and 20, and the screen layer 206 can suppress the free air flow between the layers. However, the disadvantage of this structure is that the freely suspended screen 206 will help to isolate water from the enclosed spaces between the breathable membranes 200 and 210, so that liquid water can be kept inside the spiral wall cavity. All the structures just described provide additional longitudinal reinforcement, each with its own advantages and disadvantages.

Invention Description (i〇) has been specified. Some or all of the layers are formed, for example, between the breathable membrane and one or more beads, between the beads and the screen, and between the screen and the breathable film. Such a preferred compatible material is used for each construction element. For example, although silk melt polyacetate beads can be fully mechanically bonded to nylon or polypropylene mesh, they may develop brittleness and / or prevent the beads from bonding to adjacent layers of polyester-based breathable membranes, such as Section 93 Figure specific embodiment. The results are better. All three components have the same base material, for example, polyester beads and screens are better for the polyacetate-based product Simpates. Further changes in the foregoing specific embodiments include replacing the outer breathable layer with a perforated non-permeable layer in the outer, c, d, g, h & i diagrams. However, this change does not provide a complete insulation effect while maintaining the transmission of liquid vapor from the insulated space, allowing further transmission through the conductor wall. A shaping device suitable for manufacturing the respiratory tube product of the specific embodiment shown in Figs. 9a-9i is shown, for example, at _. In particular, a device for forming a catheter of a gadolinium or% map is shown. The device comprises a shaped part 300, preferably of a known type, comprising a plurality of rotating rods arranged around a central branch pole. Each rod is extended outward from the gear box inside the frame 301 and rotated by the gear box. At least in the tube forming area, the rotating rod follows a spiral path. The pitch angle of the rod relative to the support rod controls the pitch angle of the tube. Such a machine is, for example, a helical pipe mandrel from OLMAS SRL. The tube formed on the formed article is rotated by the movement of the rotating rod and advances in the direction of arrow 303. The advancement speed of the shaped part is selected relative to the rotation speed, so that the spiral pitch of the tuning band placed on the shaped part 300 is slightly smaller than the width of the strip, so there is a narrow overlap of adjacent turns. The first extruder 304 extrudes a strip 314 of breathable polymer material.

Description of the Invention (11) Three books 14 are deposited on the formed article 300 in a spiral manner by the action of the formed article. ▼ The spiral and spiral forming pitch of 314 is slightly smaller than the width of 314. The spiral-like deposits with ... form the thin, breathable walls of the catheter. A second press 3305 extrudes beads 315 made of polymer material. Beads 315 are deposited on the formed part at the joints or overlaps between the neighborhoods 3M of each zone, and join along to form raised beads 201. The reinforced film strip 316 is unrolled from the reel 306, and its edges are deposited on the neighboring beads 201. The spirally deposited reinforcing strip 316 forms a reinforcing layer 206. A third extruder 3007 forms a second molten polymer bead?. The beads are deposited helically along the overlap between the reinforcing strips 316 adjacent to each turn. The fourth extruder 308 squeezes the second breathable polymer strip 318. The second breathable polymer belt 318 is deposited on the shaped part 300 and overlaps the adjacent beads 3 and 7 adjacent to each turn. The adjacent belt 318 overlaps, and at the same time is fully melted and fused to the second bead. On this page, an external respirable sheath is formed on top of 209. 2 10 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition to the application of molten beads to join the film overlap, other active fusion techniques can also be applied. It can be used in particular for a layer of longitudinal reinforcement or linen adjacent to a breathable membrane. Active methods include hot air welding, hot rolls or radio-frequency welding. When the hot air is connected, a stream of hot air is blown onto the overlap of the breathable membranes adjacent to the ®, melting or fusing adjacent edges. This approach was a success. It is used for thermal light welding, and the contact overlap portion after heating is rolled to fuse the thin pieces together. Similar to hot air welding, hot roll welding relies on direct local heating of the film stack. For RF welding, the film acts as an insulation between a pair of boards. An electric current is applied between the plates to melt and fuse the overlapping portions of the plastic film. The plate can be in the form of a pair of rollers. One turn of the field heavy line. The paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm). 14 A7 B: V. Description of the invention (12) Reported on the inside of the tube and the other It is placed on the outside of the tube or in the form of a light and formed part of a rotating rod. Setting the rod as a pro (or stiffening and forming mandrel) allows the radio frequency to be continuously performed, and has similar advantages to hot air welding and hot roll welding. In another variation of the manufacturing method, the breathable membrane tube can be manufactured with a longitudinal connection. Instead of forming a continuous spiral strip. In such a specific embodiment, it can be wrapped around the mandrel when the wider diaphragm is pressed or unrolled from the reel. The longitudinal edges are coincident and any of the aforementioned methods are used to make the seam material. Then the rotary press is used to squeeze the reinforced beads on the plastic film. The further strengthening layer or film layer and the spiral beads can be applied by extra wrapping and then rotating the extruder if necessary.

A preferred method for forming a tube according to the specific embodiment of Fig. 8 will be described with reference to the apparatus of Fig. J 2. Especially for the machine of Fig. 12, the breathable tube 3 50 is made by spirally wrapping a breathable polymer strip 360 to be formed into a strip or a strip formed on a rotationally formed part 370. The strip 360 is unrolled by the short axis 373. Adjacent turns of breathable polymer 360 overlap. The overlapping edges are fused by thermal fusion. The heat-welding system is performed continuously by hot-air-melting joint 375. The rotating and advancing of the shaped part 37 passes through the seams adjacent to each of the turns 370 over the head 375. The beads 363 are extruded by the extruder 381 on the overlapping portions of the breathable belts 362 adjacent to each other, thereby forming spiral reinforcing beads 353. The freely rotatable wire laying head 376 is located on the formed part behind the bead extruder 381. The rotating head 376 carries a plurality of short tubes 379 and holds a reinforcing wire 351.

A: 5. Description of the invention (15) is wound on the tube or catheter assembly. Referring to Figure 3, other types of catheters such as those shown in Figure I can be made by co-pressing a breathable material (here the material is a suitable pressure-adjustable material) and a plastic material that forms the rest of the catheter wall. A suitable common broadcasting die 9 is illustrated in FIG. 3, in which a pair of die opening peripheral sections 7 have a breathable plastic material squeezed through them, and the remaining sections 8 of the ring-shaped extrusion opening have non-permeable plastic wall material. Squeeze through it. The purpose of the breathable area of the catheter wall is to allow water vapor to diffuse from the expiratory limb along the path of the respiratory catheter regardless of the specific drainage location. This eliminates the need for the humidified gas to dry as it flows through the extremity, allowing condensation to accumulate inside the extremity. This further reduces the humidity of the gas reaching auxiliary equipment such as filters, vents, etc., reduces the risk of condensation water accumulation, and improves its operation. According to yet another characteristic aspect of the present invention, and Figures 4 and 5 illustrate by way of example, a catheter incorporating one or more long breathable membranes is further incorporated into a coaxial breathing circuit as a passive humidification device. With particular reference to the sectional view of Fig. 4, the coaxial breathing circuit includes an outer catheter 1 and an inner catheter 10. Preferably, due to the heat transfer factor, the inner gas 10 carries a suction current in the space 12. The expiratory air flow is preferably contained in the intermediate space 13 between the inner duct 10 and the outer guide 11. This airflow configuration is indicated by arrows 20 and 19 respectively in FIG. 5. The inner catheter 10 has been described with reference to Figures 1, 2 and 3 on the wall 1 to form one or more longitudinal strips 2 and 3 of the respiratory membrane. The humidity of the expiratory space 13 passes through the respirable membrane segments 2 and 3 to humidify the inhaled sulfur of the inspiratory space 12. The breathable membrane exerts its effect according to the relative partial pressure of water vapor, and can achieve substantially passive humidification of the suction air when flowing in a countercurrent configuration.

Description of the invention (16) Referring to Fig. 5, it shows a circuit configured to include the coaxial circuit of Fig. 4. Wang Xian is a circuit configured to include the coaxial circuit of Figure 4. In this circuit, the official has a patient-side connector 15 and a vent-port connector ι6 having an inhalation port 17 and an exhalation port 18. Inhalation 20 and exhalation 19 flow in opposite directions to each other. With coaxial guides, the vents do not cause air leakage from the internal ducts. This type of leak may cause a short circuit for the patient, indicating that the patient cannot be supplied with sufficient oxygen. This short circuit can be detected by setting a sensor on the patient side. Alpha is better sensed. Can be seated on the patient 鳊 connector 丨 5. A short circuit closer to the vent will cause the patient to continuously breathe close to the patient's air volume. As a result, the approach of the catheter can be detected by a carbon monoxide sensor directly detecting an increase in carbon dioxide concentration at the patient's end. Such sensors may include any number of sensors as currently available on the market. In addition, this repeated beer suction can be detected by monitoring the patient's connector 端 gas temperature. A temperature rise above a predetermined level indicates repeated breathing. In addition to the aforementioned reduction or elimination of the formation of condensate in the inner tube or outer tube ⑺ or crotch 'and maintaining the average temperature of the gas flow through the duct, it can be installed inside the gas space 12 or 13 or in the duct A heater device such as a heater resistance wire is provided inside the inner tube or the outer tube inside the wall itself. One possibility is that the heating H-line also serves as a reinforcing support (spiral line 25 in Fig. 4). The support is located inside the inner conduit 10 or inside the conduit outside the coaxial conduit. Another type of breathing circuit component applicable to the present invention is a catheter seat. The catheter hub is connected between the patient interface components such as mouthpieces, nasal masks, or the dual limbs of the endotracheal tube and the breathing circuit. The connection to the double limbs of the beer suction circuit is usually through the M3318 A7 B7. V. Description of the invention (17) The connection through the wye connector. Depending on the patient's inspiratory and expiratory cycles, the limbs of the breathing circuit each play a different role, with one limb acting as an inspiratory catheter and the other limb acting as a beer catheter. The catheter hub plays a dual role of calculating inhaled and exhaled gas. There are significant disadvantages to this type of catheter hub. A certain amount of exhaled air remains between the exhaled and inhaled air at the catheter hub. This part of the air was re-used by the patient. Although not unacceptable, repetitive respiration is generally not desired, and the need for enhanced oxygen supply is required when significant repetitive respiration may occur. In a well-managed ventilation system, the air system inhaled by a patient is delivered under conditions where the humidity is close to saturation and the body temperature is usually ^ it to "its temperature. This temperature is maintained by the heater in the suction duct to the air Enter the catheter seat at this point. The gas exhaled by the patient is completely saturated and returned as it flows through the catheter seat. It is further cooled. Although there is a little condensation on the inner wall during the patient's inspiration, a significant degree of condensation occurs when the patient exhales. "Condensation or rain falling inside the guide seat" is particularly harmful because it is close to the patient. Patients breathing or inhaling condensed water may cause coughing or other discomfort. The catheter hub of the present invention is illustrated in FIG. 13. The catheter seat is connected to the Weiyi joint at the vent end. The inner catheter 455 extends coaxially with the outer catheter 456. The patient end of the inner catheter is supported on the inner catheter connector 457, which in turn is supported by a support post 458 from the patient end connector 459. The other end of the inner duct 455-is supported by the inner duct joint 460, which forms a part of the vent end joint 461. In the catheter seat of FIG. 13, the vent and the inner pipe joint 46 are in communication with the suction pipe joint 462. At least part of the outer tube 456 is made of respirable paper, and it also complies with the Chinese National Standard (CNS) A4 specification (21CU 297 mm) (-V first ^^ on the back; please fill in this page on the first page) it clothing -------- Order ------ —— Line Φ-. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 20 513318 V. Invention Description (is) Made of materials. The preferred catheter 456 is entirely made of breathable material, and also includes lateral reinforcements (spiral reinforcement beads 467) and longitudinal reinforcements (axially oriented lines 490) on its outer side. When constructed in the manner described above with reference to Figures 12 and 8, the spiral beads 467 are laid between successive turns of the extruded belt and assist in the fusion and reinforcement of the overlapping portions without being crushed. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, when used, the catheter according to Figure 3 has a suction air flow through the catheter holder, as indicated by arrow .470. The inspiratory air flows through the inner catheter and is sent to the patient via the patient end connector 450, as indicated by arrow 471. When the patient exhales, whether by relying on auxiliary exhalation or otherwise exhaling, the exhausted gas enters the space around the inner catheter 455 through the joint 459, as indicated by arrow 472. These gases pass along the inside of the wall of the outer tube 456, as indicated by arrow 473; and are expelled through the expiratory tube connection 463 of the ventilation connector 46 !, as indicated by the connection. When passing through the catheter seat inside the space between the inner duct ⑸ and the outer wall 456, water vapor passes through the water vapor permeable portion of V 笞 4 5 6. It is better to breathe the entire outer catheter * $ 6 (except for the ribs). In this way, although the beer gas may slightly decrease in temperature when passing through the catheter holder to the breathing circuit connector 463, with this / decrease, the humidity decreases as the water gas passes through the breathable part of the outer tube. This can reduce the relative saturation of the expiratory air flow and reduce the "falling rain" phenomenon. The catheter seat incorporating the features of the present invention includes inspiratory and expiratory branches flowing through the catheter seat, significantly reducing repeated breathing. By lowering the temperature of the exhaled gas, even when the temperature of the gas is reduced, the humidity is reduced and the rain phenomenon is reduced. Although certain specific embodiments of the invention have been described above with reference to better and specific advantages over other specific embodiments, a variety of other combinations have also proven to be commercially useful.
