INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present disclosure relates to a needleless connector, and more particularly to a positive displacement needleless connector. C 4 Chair; 3 BACKGROUND OF THE INVENTION Thieves medical treatment often requires a medical professional to introduce or withdraw fluid from a patient. For example, a patient may need a treatment that requires a medical professional to separately withdraw urine or blood from the urethra or vein. Conversely, medical professionals may need to introduce drugs or nutrients into the patient's vein (i.e., intravenously). In order to create a fluid flow path into or from the patient, one of the methods requires the medical practitioner to use the catheter, wherein one end of the catheter is inserted into the patient. The other end of the catheter is connected to the intravenous bag via a 1V wire (IV bag) needleless connector uses a valve that allows the medical practitioner to not remove or add to the catheter (eg, 'IV bag). An embodiment of the pin-receiving connector is shown in Figures 1A and 1B. Figure 1A is a cross-sectional view of the now needle-free connector 1A. The needle-free connector 100 includes a housing 120' at the proximal end There is a female Luer fitting 101; a base 130 having a male luer fitting 1〇2 at the distal end; and a valve element 103' seated within the outer casing 120 and on the top end of the base no. 120 and the base 130 are made of a hard plastic (usually polycarbonate), and the valve element 103 is made of liquid polyfluorene, so that it is elastic and foldable. When in use, the male luer fitting 102 Connected to, for example, a catheter or female luer, and female Ruhr 201249488 fitting 101 is attached to a fluid reservoir (eg, IV bag) or male luer. Female Ruhr fitting 101 is via a second male luer fitting 106 (which has a hollow member (as shown in Figure 1B) and via the female Ruhr accessory ι The top end of 1 is inserted into the fluid reservoir. The insertion of the male luer 106 folds the valve element 103 down into the volume 104 to break the seal and create a fluid flow path. The figure shows the male Luer 106 After being inserted into the female luer 1〇1, the collapsible valve element 103 is in a folded position. The male luer 106 delivers fluid (eg, from a bag) that flows into the male luer fitting 102 around the valve element 103. The passageway and the inlet conduit or the female luer. There is a gap (or spacing, no display) in the valve element 103, which is filled with air. The needleless connector 1 is a positive displacement device, so when When a new connection is made at the female Luer fitting 101, the device 1〇〇 draws fluid from the male side of the valve (ie, adjacent the side of the male luer fitting 102). When disconnected at the female Ruhr fitting 1〇1, the device 100 pushes the fluid from the female side (ie, the side adjacent the top end of the female Luer fitting 101). The advantage of positive displacement is that when disconnected, the device 1 〇〇 discharges the fluid out of the male Luer fitting 1G2 and effectively aligns the + conduit In contrast, some devices on the market today have negative displacements. When the Dangdang _ (for example, the male Luer 1〇6) is disconnected, the device sucks a small amount of liquid from the side of the public rudder. When inhaling from the male Luer 1〇2 of the catheter attached to the venous patient When liquid is in use, blood may be drawn into the guide cavity' and if the blood remains in the lumen of the catheter, it can condense into pieces and cause health problems to the patient. The positive displacement connector is used by the male Luer (eg 'public Luer 1G6) pushes the fluid out when it is disconnected from the needleless connector, and its foldable from its Fold® state to its unfolded “avoid this problem. Fluid cleaning (from positive displacement connection ϋ) Helps prevent blood from entering the catheter tip 201249488 and thus prevents clotting/contamination and, therefore, bloodstream infection. (Second tr' when the needle-free connector 1_ female end is taken by the male luer, the valve member 103 is sufficiently flexible that it can bend the moving path k and then return after the female end is disconnected The reason for this is that the 'needle-free connector (10) itself is resealed and formed into a flat surface, and the (four) swab can be sterilized at the top surface Φ1Η). ▲ ▲Before connecting the unit to the unit using the needleless connector (10), the needleless connector _ will contain some lines. Remove this air before using the PIN pin connector _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In terms of money, in order to remove this gas, the medical practitioners 倒 缺 录 (4) that includes the recording ejector attached to the needleless connector. Then, the salt solution is pushed through the needleless connector&apos; so that air is expelled from the connector. (This method is known as perfusion (ΡΗ_)' and the minimum volume required to remove all air from the needle-free connector is known as the perfusion volume.) Some medical practitioners prefer to choose a smaller perfusion volume. The needle is attached to the connector to reduce the delay in drug delivery. After the needle-free connector is priming, the medical practitioner typically connects the male end 102 to the catheter (no _. The medical practitioner connects the male luer (no display) from the ιν bag to the needle-free connection. The medical practitioner connects the end of the syringe 106 to the female Luer fitting (9) as shown in Figure 1B. The needle-free connector 1 is referred to as the outer casing 120, the base 13 and the valve element 103. The valve element 1〇3 has a flange 1〇5 which is a portion having an outer diameter larger than the body of the valve element 103. The outer casing m has a shoulder yang, and its 201249488 is similar to the flange 105. 1〇5 is firmly placed between the base 13〇 and the shoulder 107, thus creating a seal between the flange 1〇5 and the base 13〇. The reason for the seal is such that the air in the space can be discharged without There is air entering the fluid flow path from the male luer 106 to the male luer 1 〇 2. Although not shown herein, in the y-axis direction extending from the threaded portion of the base 130 to the valve element 1 〇 3 There are two venting holes (which allow air in and out), which serves as the valve element 103 Compressed and uncompressed without mixing with the fluid. Once combined, the outer casing 120 is in close contact with the base 130 at the interface 115. The flange 105 increases the overall width of the valve element 103, and the connector 1〇〇 allows fluid to pass around the flange 105 flows, thus causing the connector 〇() to become self-contained. As a result, the connector 100 can look large when compared to a catheter (not shown), particularly when the connector 100 is placed against the newborn's skin. A typical use of the connector 1 is to tape the guide to the patient's skin at a location near the catheter coupling to the connector 1 . However, the wide shape of the connector 100 can cause the connector 100 to be uncomfortably In addition, the width of the connector 1 可 can cause a large perfusion volume. SUMMARY OF THE INVENTION [0007] A number of specific examples include a connection state having a valve element fixed to a base. For example, in a specific In an example, the embodiment valve member is flush with the base, wherein the two members are mated. In another embodiment, the base and the valve member are coupled to each other to produce a housing having a maximum outer diameter that is less than the outer casing. Combination of inner diameters. A number of specific examples reduce or eliminate the flange so that the overall width of the valve element and connector 201249488 can be reduced (when compared to the solution previously shown in Figure 1A &amp; 1B), A common technique for eliminating the flange and securing the valve member to the base includes the use of a snap fit that mates the valve member to the base, although other embodiments may use other techniques. Other specific examples include making a connection.

Fig. 3A is a cross-sectional view, whereas Fig. 3B shows the exterior of the connector 2, and both of the 3A and 3B shows that the base 21 is fixed to the valve member 22 (). In this particular example, base 21 and valve member 220 are coupled together using an internal lock male/female fitting 250 (referred to herein as a snap fit for convenience). The top end of the valve member 220 (which is the female portion of the snap fitting 25A) is made sufficiently small to have a tight sealing pressure at a corresponding portion of the base 210 that forms the male portion of the snap fitting 25〇 squeeze. In many embodiments, the seal at the snap fitting 250 is airtight (at least at normal operating temperatures and pressures) to maintain air and fluid separation in the connector 200. During manufacture, the base 210 and valve member 220 can be solidified by pushing them together by hand or by machine. In some embodiments, about one pound of force is sufficient to make the connection and about two pounds are sufficient to break the connection, although multiple specific examples may vary. Although Figures 3A and B show a snap fitting 250, the scope of the specific example is not so limited. For example, other specific examples may use different types of solid fittings such as threaded combinations or other fittings. In a typical embodiment of Figures 3A and 3B, the outer surface of the base 21 and valve member 220 are flush at the snap fitting 250. For real-world devices, it is to be understood that the outer surfaces of valve element 220 and base 210 will be less precisely flushed 'but that in some embodiments, some tolerance (eg, about 2%) is acceptable. Brahman. Accordingly, the connector 200 replaces the flange of the conventional positive displacement device (e.g., the flange 105 of Fig. 1A) with the snap fitting 250 and the outer surface that is flush shown in Figs. 3A and 3B. Thus, the shape of the valve member 22A has a narrower appearance of 201249488 and can be used in a narrower appearance connector. The base 210 is secured to the valve member 220 to form a combination that fits into the outer casing 230. The connector 200 mates the base 210 with the outer casing 230 using a slightly "v" shaped fitting. The complementary surfaces 211 and 233 are substantially v-shaped but have a slight curvature and are disposed together to properly hold the base 210 when the base 210 is inserted into the outer casing 230. When inserted into the base 210, the complementary surfaces 211, 233 are automatically aligned with the base 210 in line with respect to the outer casing 230, acting as a cam. Thus, if the pedestal 210 is inserted at any arbitrary number of angles from the straight line, the &apos;complementary surfaces 211, 233 (the contact) will transfer the susceptor 210 into position. As a result, the base 210 is accurately seated, and after the close, when the end flow passage 213 is connected to the male luer output of the base 210, the air vent 212 will be able to vent to the atmosphere. In this specific example, the end flow passage 213 and the air venting opening 212 are perpendicular to each other. Therefore, one of the two air vent holes 212 is shown in Fig. 3B, however the end flow path 213 is shown in cross section in Fig. 3A. Flow and exhaust are shown in more detail in Figure 4. Fig. 4 is a perspective view of a typical connector 200 according to a specific example when in use. In Fig. 4, the flow system is from the male luer connector 41 (which is engaged with the female luer fitting 231), via the outer casing 230' via the male luer output port of the base 21 and into the female luer fitting 402. And transfer. This embodiment may include transferring fluid from the IV bag (not shown) into the patient's commercial stream. While Figure 4 shows inflow into a patient, it is to be understood that various embodiments of the invention also facilitate fluid flow from the patient. When there is no connection at the female luer fitting 231, the valve element 230 is in the female luer

This seal prevents fluid from flowing through the connector 2 when not in use. Likewise, the seal at the proximal end of the fitting 231 creates a smudgeable Hush surface. The seal at the proximal end of the female Luer fitting 23 1 and at the shoulder 234 is shown in Figure 5. During use, the male luer fitting 401 folds the valve element 220 and breaks the seal at the shoulder 234 and at the proximal end of the fitting 231. The fluid then flows freely around the valve element 230 and through the outer casing 230 via the proximal flow passage 403 (which forms the inner surface of the outer casing 230). The close contact at the surfaces 211, 233 blocks the fluid so that the fluid flows around the v-shape and into the end flow channel 213, wherein the fluid is directed through the male luer output of the susceptor 210. Air from the space 221 is vented to the atmosphere via the air venting opening 212 and into the threaded compartment 404 (which is part of the male luer fitting formed by the base 210 and the outer casing 230)*. The air passage is defined by the venting opening 212 and the inner surface of the outer casing 230, and the sealing at the surfaces 211, 233 creates a seal that keeps the air flow separate from the fluid flow. The threaded compartment 404 is not airtight (even when engaged with the female component 402), thus allowing the spacing 221 to communicate with the surrounding atmosphere when the valve element 220 is compressed (as in Figure 4) or not compressed. Fig. 5 is a cross-sectional view of a typical connector 200 according to a specific example, which is rotated ninety degrees from the sections of Figs. 2A, B and 3A, B. Note that in Figure 5, the air passage from the interval 221 to the atmosphere. The air passage includes a single exhaust hole 501 (formed in the base 210) and a vent hole 212. The single row of vents 501 and venting holes 212 form a substantially "Y" shaped air passage. This is compared to the previous design (no display) which includes two or more separate vents formed in the y-axis direction ("axial") that connect the atmosphere directly to the space. 201249488 During the prior art manufacturing process, using injection molding techniques, and using long, thin pins inserted into the mold cavity (when the material is hot) produces two or more separate rows when the mold is opened, In addition to the long, thin inspection, two or more separate vent holes are formed. However, long, thin plugs have a tendency to break during use. The general rule is that the shorter and thicker plugs last longer. In contrast, the susceptor 210 has relatively short and short venting holes 212 that can be formed in the mold by metal sheets of corresponding shapes. The air passage has a triangular width in each of the vent holes 212 from the central axis to the outer surface of the base 210. Correspondingly shaped metal sheets (not shown) are longer and thinner than conventional techniques, and therefore less susceptible to breakage. The single channel 5〇1 is made relatively wide and placed in a portion of the base 210 (which corresponds to the male portion of the snap fitting 250). Again, because the single channel 501 does not have to traverse the entire length from the spacing 221 to the threaded compartment 404, it avoids clamping the fluid flow path. In addition, the single channel 501 is not made of any long, thin pins. Figure 6 is an illustration of a typical connector 200 that is combined and ready for use in accordance with one embodiment. The outer casing 230 can be made of a material including polycarbonate, polystyrene, and acrylonitrile butadiene styrene. The outer casing 230 includes a female luer fitting 231 that, in certain embodiments, conforms to the standard 594. Similarly, in some embodiments, the male luer configuration at the distal end of the outer casing 230 and with the base 210 conforms to ISO standard 594. Valve element 220 is disposed within outer casing 230 and may be fabricated from an elastomeric material such as polyoxyxene rubber which is deformable and biocompatible.

In the slot and key configuration, the base 71 has a protrusion (key) that is sized to fit into a slot in the inner surface of the housing 730 (or vice versa). During manufacture, the base 710 and valve element 220 are inserted into the housing 730 and rotated until the slot mates with the key. Then, the base 710 is brought into close contact with the outer casing 730. The scope of the specific examples is not limited to slots and key fittings or v-shaped fittings, and various techniques for mating the base and the outer casing may be used in various embodiments. Figure 8 is an illustration of a typical method 800 for fabricating a positive displacement needleless connector, according to one embodiment. Method 800 can be performed, for example, by a human and/or one or more machines. In block 801, the distal end of the valve member is secured to the proximal end of the base. The - is fixed between the valve member and the base to create a seal that separates the spacing from the fluid flow path between the first and second luer fittings. Block 801 produces a combination comprising a valve element and a mating pedestal (such as shown in Figure 3A). In one embodiment, the valve element and base are mated using snap fittings, although other securing techniques may be used in other embodiments. In block 802, the valve element and base are disposed within the housing. For example, a v-shaped fitting (such as shown in Figures 3A and 3B that automatically aligns the base to the housing) can be used, although other accessories such as 'keys and slots can be used. When the valve and base are disposed within the housing, the proximal end of the valve member creates one or more seals at the proximal end of the housing. In block 803, the base and outer casing are permanently secured. A variety of techniques can be used in block 803, such as ultrasonic welding, coating adhesives, and the like. In this embodiment, the base and the outer casing are tightly disposed together to create a seal that separates the air discharge path from the fluid flow path after the base is permanently secured to the outer casing. A plurality of specific examples are not limited to the method of the second embodiment, as may be added, omitted, rearranged or modified. Some specific examples may have one or more advantages over previous solutions. In one point of view, the size of the flange reducing component and the ϋ (4) are sequentially eliminated. With the sister tilting connector, the connector usually has a smaller perfusion volume. Similarly, it reduces fluid and waste and is more visually appealing to health care professionals.
