Description

DIAPHRAGM FLOW CONTROL ASSEMBLY BACKGROUND OF THE INVENTION Field of the Invention This invention relates to a diaphragm fluid flow control assembly that seals against leakage of fluid prior to insertion of, during insertion, and while inserting, and after removal of, a tube. Hollow blunt plastic or needle.

Discussion of Related Art The storage of fluids in sterile containers, and the removal of fluids from containers, while maintaining fluid sterility, is an important part of the treatment of patients by the physician or by medical personnel. Traditionally, sharp pointed objects, such as needles, have served for the. extraction of fluids. Recently, there has been much concern in the medical field of an inadvertent sting from both patients and medical personnel. Recently, different mechanisms and insurance devices have been developed that contain sharpened protected or enclosed. The focus of these products has been an element of mechanical insurance.

The vast majority of these devices use sharp pointed needles. There has been relatively little attention to the use of blunt or moderately sharp needles. To use a blunt needle, a pre-punched seal is required. Currently, a seal is available consisting of an extended rubber rubber stopper that fits into, and is compressed by, the walls of a hollow tube. A portion of the plug can be formed in such a way that it fits around the end of the hollow tube. This plug is bulky, and derives compressive forces to close the central hole when squeezed when it is inserted into the tube. However, to use this seal, the user must simultaneously keep an insurance mechanism open, while forcing a blunt plastic tube through an extended section of the tube occupied by the rubber rubber seal. The extended stretch of this seal requires significant force to push a blunt tube or needle through it.

COMPENDIUM OF THE INVENTION This invention overcomes the drawbacks of conventional diaphragms currently available. With the diaphragm of this invention, during the entire time the tube is inserted, the diaphragm is in a sealing coupling with the external surface of the tube, while a free flow of a liquid inside the hollow tube occurs. The diaphragm functions as a seal for containers typically used in medical applications, such as vials, syringes, and intravenous bags. These containers can be loaded with quantities of fluids that are extracted when the diaphragm is penetrated. The diaphragm serves as a leak-proof seal that maintains the sterility of the container containing fluid, and yet allows a desired amount of fluid to be easily removed while maintaining the sterility of the fluid content during extraction. The diaphragm assembly can be effectively combined as a component of a fluid transfer or control system when a separate mechanical safety mechanism is used that secures a device, which contains the tube to be inserted through the diaphragm, with the structure that contains fluid inside of which the diaphragm is mounted. It is a feature of this invention to provide a fluid-proof self-sealing perforated diaphragm that can be easily penetrated by a plastic tube or moderately sharp or blunt end needle to form a fluid-tight seal with the tube or needle when it is inserted through the diaphragm. For the purposes of this invention, a tube or needle has a blunt tip when the plane of the opening of the tube or needle is at an angle of substantially 90 ° with the outer surface of the tube or needle. Another feature of the invention is to provide a perforated self-sealing diaphragm, in such a way that, after removing the tube or needle inserted through the diaphragm, the diaphragm closes and forms a fluid-tight seal. Yet another feature of the invention is to provide a self-sealing, penetrable, and reusable diaphragm assembly for serving as a cap for retaining fluid within medicine bottles, pre-filled syringes, intravenous bags, and the like. A further feature of the invention is to provide a self-sealing and reusable diaphragm assembly, and a conduit serving as the female insert for coupling and securing with a quick-connect fluid coupling assembly that serves as the basic building block in a unified system for fluid transmission in the fields of medical care and health care. These and other features and advantages of the invention are provided by a diaphragm assembly comprising a perforated circular disk of rubber or other suitable material; a plastic conduit or tube segment having an inner surface with a circumferential shoulder or step; and a snap ring that fits into the plastic conduit or tube segment, which stops the circular disk inside the tube, squeezing the circular disk against the internal shoulder of the conduit, and creating compression forces directed inward toward the shaft duct core, to form a fluid-tight seal. Preferably, the compression forces created when the snap ring presses the edges of the perforated circular disk against the inner shoulder of the conduit, deform the circular disk into a domed or domed form, having a concave side and a convex side, Such a way that the disc is sealed against the flow of liquid from the volume of the duct that limits the convex side of the disc to the volume of the tube that limits the concave side of the disc. It is preferred that the difference between the inner and outer diameters of the snap ring be greater than the distance from the inner surface of the plastic conduit to the shoulder or step end, measured along a normal line to the inner surface of the conduit . The diaphragm is preferably engaged and secured within a quick connect coupling assembly. The coupling assembly comprises a primary body including a centrally disposed elongated channel extending therethrough coaxially to the longitudinal axis thereof, a non-flexible central portion, a flexible retention portion, and a portion integrally joining the portion not flexible with the flexible portion; and a hollow cylindrical shaped needle that pierces the diaphragm incorporated in and coaxial with the longitudinal axis of the primary body, having the outer surface of the needle integrally attached to the surface of the non-flexible portion of the primary body, which has the outer surface of the needle integrally attached to the surface of the non-flexible portion of the primary body, and extending longitudinally beyond the non-flexible portion by a length sufficient to terminate inside the flexible portion of the primary body. By using the diaphragm assembly of this invention, it is possible to construct a fully assembled unified fluid system wherein all of the gates of the system are the gates of this invention, or a combination of the gate of this invention and other conventional gates, depending of the applications in which the system is placed.

DETAILED DESCRIPTION OF THE INVENTION Referring to Figures 1 and 3, the complete diaphragm assembly 100 is shown in a cross-sectional side view, comprising a domed or dome-shaped diaphragm 1, having a perforation 14, a pressure or retaining ring 13, and a plastic conduit 15, having an elongated channel 121 centrally disposed along a longitudinal axis, and having a circumferential shoulder or internal surface step 101, which surrounds the longitudinal axis. In Figure 2 a top view of the diaphragm assembly 100 is shown, as seen towards the concave surface 103 of the diaphragm 1. Figure 3 shows the diaphragm 1 and the retaining ring 13 mounted inside the conduit 15, in a coupled position, with a blunt plastic needle or conduit 27. The Figure 1 shows the diaphragm assembly in the decoupled or at rest position, either before the insertion of the conduit 27, or after removing the conduit 27. The diaphragm 1 has a convex surface 102, a concave surface 103, and is held in place. its position inside the conduit 15 between the pressurized or retaining ring 13 and the shoulder of the tube 101. The diaphragm 1 divides the space 1 inside the conduit 15 in the two volumes 22 and 21, the volume 21 being joined with the convex surface of the diaphragm 102, and the volume 22 joining with the concave surface of the diaphragm 103. The front surface 113 of the retainer ring 13 is positioned at a distance 114 from the proximal end 115 of the tube 15. The front surface 116 of the shoulder 101 is located at a distance 117 from the end of the tube 115. Referring to Figure 5, the tube or conduit 15 having a distal end 120 opening to a fluid container or reservoir in the form of an intravenous bag 110, a syringe 111, or a bottle of medicament 112. There are compression forces 24 and 25 inside the diaphragm 1, and serve to seal the perforation 14 in the absence of a conduit, to form a fluid-tight seal with the outer surface of the duct 27, and to form the diaphragm 1 in a dome shape, with the concave surface 103 and the convex surface 102. The forces 24 and 25 are created when the ring 13 is pressed in the tube 15, trapping and squeezing the diaphragm 1 around the periphery against the front surface 116 of the internal shoulder 101 of the conduit 15. The perforation 14 may be in the form of a straight line cut, two cross cuts of a straight line, a circular shape, or want different suitable geometric shapes. The dimension machine of the perforation 14 is usually slightly smaller than the outer diameter of any tube or conduit 27, but can be of any size, to form a leak-proof seal around the external surface of the conduit 27. Referring to the Figure 4, the radial width of the snap ring 13 is shown as 104, and the radial width of the shoulder 101 is shown as 105. The radial width of the ring 104 exceeds the radial width of the shoulder 105. When the latex, rubber, elastomer, The thermoplastic stock or any other suitable material for the diaphragm 1, seeks to expand against the tightness of the ring 13, can expand only in the region 106, where the shoulder 101 is not present. The expansion in the direction 107 forms the diaphragm 1 in a dome-shaped surface, and which creates compression forces 24 and 25. Before being squeezed between the ring 13 and the shoulder 101, the diaphragm 1 is in the shape of a circular disc ado contained essentially in a plane. The tightening by the ring 13 of the diaphragm 1 against the front surface 116 of the shoulder 101, causes the diaphragm to change shape from a circular disc to a circular dome shape having a concave surface 103 and a convex surface 102. The penetration of the Diaphragm 1 is made by moving the duct or blunt needle 27 in the direction 30 towards the concave side 103 of the diaphragm 1, and passing through the diaphragm 1 from the volume 22 to the volume 21. When the conduit 27 passes through the diaphragm 1 , and remains in the coupled position shown in Figure 3, the compression forces 24 and 25 force the surface of the diaphragm 1 to a sealing engagement with the external surface 28 of the conduit 27. When the plastic conduit or tube is removed 27 , the forces 24 and 25 cause the perforation 14 to close, again causing the diaphragm 1 to provide a fluid-free leak-free surface. Figures 5 (a) -5 (c) show the diaphragm assembly as a part of an intravenous bag 110, a syringe 111, and a bottle of medicament 112. In Figures 5 (a) -5 (c), the external surface 130 of the conduit 15 is shown having a protruding detent member 131 with an inclined surface 132 facing the end of the proximal conduit 115, and a vertical surface 133 that faces the distal end of the conduit 120, completely surrounding the conduit 115. The arresting member 131 is designed to be coupled with an insurance mechanism, such as that described in the United States of America Number 5,221,273, the disclosure of which is incorporated herein by reference. Referring to Figures 6 and 7, the complete quick connect coupling assembly 210, comprising a quick connect primary body 212 in a coupled position, with a diaphragm assembly and conduit 238 is shown. Figure 7 shows the body primary 212 of the connector by itself, without engaging the conduit of the diaphragm assembly 238. The primary body 212 of the connector 210 is formed of a flexible retaining end portion 214, a non-flexible central portion 216, and an end portion. opposite 218. A central hollow axial tubular structure 220, such as a needle, extends from a location 222 in proximity to the distal end 224 of the flexible retaining end portion 214, through and along the longitudinal axis of the primary body 212. , to a location 434 in proximity to the distal end 400 of the flexible end portion 218. The tubular structure 220 is integral with the primary body in s central portion 216. An outer wall 230 joins, supports, and separates the flexible retaining end portion from the non-flexible central portion of the primary body by a fixed separation distance, with two similar opposite openings 226 appearing in the wall 230 as shown in FIG. sample. The particular portions of the wall 230 that form the connection between the central portion 216 and the end portion 214, are identified as the side walls 256 and 258. There is a similar and opposite end structure at the opposite end portion 218, which it connects to, and is separated by a fixed distance from, the central portion 216 by the same external wall 230. The outer wall 230 at this end also has two similar opposite openings 228 formed from the wall. The tubular structure 220 contains an axial central passage 232 running lengthwise through the tubular structure, and suitable for fluid transmission. The two end segments of the tubular structure 220 consist of sharp, slightly sharp, or blunt ends 234, suitable for piercing a diaphragm made of latex or other similar material. The relative positions of the retaining member 214 and the conduit 238 before, during, and after the insertion of the conduit 238 into the primary body of the connector, are illustrated and explained below with reference to Figures 8, 9, and 10. , respectively. In Figure 8, connector 210 and conduit 238 are shown prior to insertion. The conduit 238 is pushed in a direction 278, and inserted into the connector 210 with the central axis 280 of the conduit 238 coinciding with the central axis 2100 of the connector 210. The end 244 of the conduit 238 incorporates the diaphragm 14. Figure 9 illustrates the two components of the connector during insertion, where forces 264 and 262 are exerted on the wall 256 and 258, respectively, and the walls 252 and 254 react moving outward, so that the distance of the separation between walls increases from 251 to 251 '. The distance 251 'slightly exceeds the maximum diameter 248 of the stopping member 242, thereby allowing the stopping member to pass through the flexible retaining end portion 214. As the leading edge 239 of the conduit 238 enters the the flexible retaining end portion 214, and meets the end 234 of the tubular structure 220, the diaphragm 14 incorporated in the front edge of the duct is pierced. As the conduit 238 continues to be urged in a direction 278 and into the primary body 212, the trailing edge 282 of the stop member 242 passes the surface edge 240 of the flexible retaining end portion 214 of the connector. When this occurs, forces 262 and 264 are removed, and end portion 214 returns to the condition and shape initially indicated in Figure 8, prior to insertion. Figure 10 shows that, after insertion, the edge of the connector 240 and the edge of the stop member 282, abut and press firmly against each other, such that the conduit 238 is securely held in place, and The primary body 212 is secured at the same time. A fluid leakage proof seal has been formed at 284, where the diaphragm 1 surrounds the tubular structure 220. An important aspect of this invention is illustrated in Figure 11: the use of a blunt needle, tube, or conduit 27 within connector 210. The use of a blunt needle is made possible by the pre-perforated diaphragm 1 of this invention. Only a slight push of the blunt needle 27 into the bore 14 previously formed in the diaphragm 1 is required for the operation. Figure 11 shows the blunt needle 27 and the diaphragm 1 before the insertion of the blunt needle 27 into the diaphragm 1. Although the blunt needle 27 is contained within the duct 210, as shown in Figure 6, only the blunt needle 27 is illustrated in Figure 11. The opening 301 of the blunt needle 27 is contained within the plane 37, which is substantially perpendicular to the external surface 368 of the blunt needle 27. Figure 12 shows a blunt-tipped needle 27 partially inserted in the perforation 14 of the diaphragm 1. The blunt front edge 301 of the needle 27 gently opens the perforation 14 without cutting on the surface 380 of the perforation. The needle 27 moves in the direction of arrow 381 during insertion, and in the direction of arrow 382 during removal. During insertion and removal of the needle 27 from the diaphragm 1, the surfaces 380 of the perforation 14 remain in a sealing contact with the needle, preventing the leakage of fluids, air, or foreign matter into or from the sealed container or conduit by the diaphragm 1. As shown in Figure 13, when the needle 27 is fully inserted through the perforation 14 of the diaphragm 1, the surface 380 of the perforation is pressed tightly pressed against the external surface 368 of the needle. 27, forming a tight seal. The outer diameter 374 of the blunt needle 27 will be from about 2,032 millimeters to 3,048 millimeters, the internal diameter 374 will be from 1,016 millimeters to 1,397 millimeters. These dimensions will vary depending on the type of needle, tube, or conduit used in the particular application in which the assembly is used. Figures 14 to 18 demonstrate the superiority of the combination of the blunt needle and the predrilled diaphragm of this invention, on the conventional sharp needles used with the diaphragm assembly of this invention. Figure 14 shows the sharp pointed needle 451 and the diaphragm 1, prior to the insertion of the needle 451 into the diaphragm 1. The leading edge 401 of the needle 451 is contained within the plane 470, which makes an angle 471 with the outer surface of needle 472. In a blunt needle according to this invention, angle 471 is substantially equal to 90 °. Figure 15 shows a sharp pointed needle 451 partially inserted into the diaphragm 1, to approximately the same depth shown in Figure 12. Figure 16 shows the sharp pointed needle 451 inserted further through the diaphragm than in the Figure 15, but not all the way. Figure 17 shows the needle 451 completely inserted into the perforation of the diaphragm 1, and passed through it. Figure 18 shows needle 451 and diaphragm 1 after a complete removal of the diaphragm needle. As you can see starting from Figure 15, the insertion of the sharp pointed needle 451 to the depth 551, causes the front edge 456 of the needle to cut into the piercing wall 380, thereby cutting or lacerating a piece of the diaphragm 1. In Figure 12, in FIG. In contrast, the front edge of the blunt needle 27 slides past the perforation wall 380, without damaging the diaphragm. Figure 16 shows the additional damage caused by the sharp needle 451 as it continues into the perforation of the diaphragm. When the length of the front edge 463 of the needle 451 exceeds the thickness 464 of the diaphragm 1, there is a two-way leakage path 465, 466, as the needle is being inserted, which allows the blood or other fluid to leak inwards or from the container or conduit sealed by the diaphragm 1. In contrast, the blunt needle 27 shown in Figure 12 essentially does not have a forward edge portion, since its front edge 301 lies in a plane perpendicular to the external surface of the blunt needle, so that a two-way leak can not occur in a diaphragm pierced with a blunt needle. Figure 17 shows the residual effects of damage caused by the use of a sharp needle. Even though the two-way leakage shown in Figure 16 is not a significant problem, there remains a trajectory for leakage in areas where material 454 has been removed from the perforation walls by the passage of the sharp needle. Removal or cementing of material decreases the restoration force of the diaphragm rubber to fill in the gaps between the perforation wall and the outer surface of the needle, thus allowing fluid, air, and bacteria to escape , through the perforation of the diaphragm. This means that, once a sharp pointed needle has been used with the diaphragm assembly of this invention, the diaphragm is useless to reseal a container due to an unacceptable leakage. This problem worsens as the diaphragm reseals. Figures 12 and 13 show that this problem does not exist when using a blunt-tipped needle, - the diaphragm remains completely intact, thereby providing a release surface for a fluid or conduit container. The diaphragm assembly of this invention, in combination with the blunt-tipped needle, tube, or conduit, described herein, is suitable for use with many conventional securing systems, since its external configuration can be easily adapted to be coupled with well-known commercial sluice gates like the SAFSITEMR, CLAVEMR, and BAXTERMR gates. The modification is the same for each of these gates, that is, the addition of a stop member adapted for the given gate, such as the stop member 131 shown in FIG. 5 (a). The SAFSITE gate in use with the assembly of this invention is illustrated in Figure 19. The connector 210 is shown in a position coupled with the commercially available modified SAFSITE gate 530. A tubular structure carrying a blunt needle 220 contacts the the SAFSITE valve component 532, when the connector 210 engages the stop member 531, which is added to the commercially available gate. The valve component 532 presses on the membrane 533, allowing the flow of fluid. When the connector 210 of the gate 530 is decoupled, the membrane 533 returns to a closed position. Figure 20 shows the assembly of this invention in combination with a modified KEY gate 630. The tubular structure of the blunt needle 220 enters gate 630, forming a fluid-tight seal at 632 with gate member 633. The structure Conical gate 634 enters the blunt needle structure 220, forming a fluid passage when the connector 210 is engaged and secured with the stop member 631, which has been added to the commercially available KEY gate. When connector 210 is decoupled, the gate sealing member 633 closes to form a fluid-tight seal. Figure 21 shows the assembly of this invention in combination with a modified BAXTER gate 730. The tubular structure of the blunt needle 220 enters gate 730, forming a fluid-proof seal at 733. The blunt needle structure 220 goes to through the thick sealing diaphragm 732, forming a fluid passage when the connector 210 is engaged and secured with the stop member 731, which has been added to the commercially available BAXTER gate. When the connector 210 is decoupled, the diaphragm 733 closes to form a fluid-tight seal. In the embodiment of Figure 22, which describes the use of the diaphragm flow control assembly in a universal fluid control and application system, the gate of the diaphragm flow control assembly 100 containing the diaphragm 1 is prepared by the manufacturer as a fluid gate 15 on any of the components shown, including the bag 901, the syringe 903, the bottle 907, the pipe 909, and the catheter 911. The double male connector 210 of FIG. 7 could be worn in the pockets of the health care worker, and could be used immediately on the site to quickly and easily make any desirable connection between the different components of the system. The diaphragm fluid flow control assembly of this invention works equally well if the fluid gate 15 is replaced with the SAFSITER, CLAVER, or BAXTERR gates of Figures 19, 20, and 21, respectively. The double male connector 210 remains unchanged, so that any combination of fluid gate 15 or the SAFSITER, CLAVER, or BAXTERR gates, with the connector 210, can be used within the universal fluid control and application system of the Figure 22. Figures 23 (a) and 23 (b) illustrate an alternative embodiment, wherein the diaphragm 1 is held in place by an instantaneous adjustment or plastic cover 920, which, when adjusted in place, causes the diaphragm 1 is deformed so as not to have a dome shape. Figure 23 (a) shows the diaphragm 1 and the plastered instantaneous adjustment cover 920, whose end 921 fits in the groove 922 when it is pushed into the conduit 923. Figure 23 (b) shows the diaphragm 1 formed in a coupler after the plastic cover 920 has been adjusted in place in the groove 922. Although the present invention has been fully described by way of example with reference to the accompanying drawings, it should be understood that those skilled in the art will be able to see different changes and modifications. Accordingly, unless those changes depart from the spirit of the invention as defined by the specification and the claims, they should be construed as included therein.
