Referring to fig. 1-2, an exemplary endoscope 100 and system 200 are depicted that can include an elongate shaft 100a that is inserted into a patient. The light source 205 supplies illumination light to the distal portion 100b of the endoscope 100, and the endoscope 100 may house an imager (e.g., a CCD or CMOS imager) (not shown). The light source 205 (e.g., a lamp) is housed in the video processing unit 210, and the video processing unit 210 processes the signal input from the imager and outputs the processed video signal to a video monitor (not shown) for viewing. The video processing unit 210 also serves as a component of the air/water circuit by housing a pressurizing pump 215, such as an air supply pump, in the unit.
The endoscope shaft 100a can include a distal tip 100c disposed at a distal portion 100b of the shaft 100a, and a flexible curved portion 105 proximal of the distal tip 100 c. The flexible bending portion 105 may include an articulation joint (not shown) to assist in steering the distal tip 100 c. On the end face 100d of the distal tip of the endoscope 100 is a gas/lens cleaning nozzle 220 for supplying gas for blowing the inside of the patient at the treatment area and for supplying water for cleaning the lens covering the imager. An irrigation opening 225 in the end face 100d supplies irrigation fluid to the treatment area of the patient. An illumination window (not shown) for delivering illumination light to the treatment area and an opening 230 extending along the axis 100a for passage of tools to the working channel 235 of the treatment area may also be included on the face 100d of the distal tip 100 c. Working channel 235 extends along shaft 100a to proximal channel opening 110 distal to operating handle 115 of endoscope 100. The access opening 110 may be sealed with a biopsy valve 120 to prevent unwanted fluid outflow.
The operating handle 115 may be provided with a knob 125 for providing remote 4-way steering of the distal tip via a wire connected to an articulation joint in the bendable flexible section 105 (e.g., one knob controls up-down steering and the other knob controls side-to-side steering). A plurality of video switches 130 for remotely operating the video processing unit 210 may be arranged on the proximal side of the handle 115. In addition, the handle is provided with a double valve well 135 that receives a gas/water valve 140 for operating the blow-in gas and lens water supply operations. The gas supply line 240a and the lens purge supply line 245a run distally along the shaft 100a from the gas/water valve 140 and converge at the distal tip 100c proximal of the gas/purge nozzle 220 (fig. 2). The other valve well 135 receives a suction valve 145 for operating a suction operation. Suction supply line 250a travels distally along shaft 100a from suction valve 145 to an engagement point in fluid communication with working channel 235 of endoscope 100.
The operating handle 115 is electrically and fluidly connected to the video processing unit 210 via a flexible umbilicus 260 and a connector portion 265 extending therebetween. The flexible umbilicus 260 has a gas (e.g., air or CO 2 ) Supply line 240b, lens wash supply line 245b, suction supply line 250b, lavage supply line 255b, light guides (not shown), and electrical signal cables. The connector portion 265 connects the light source 205 in the video processing unit with the light guide when inserted into the video processing unit 210. The light guide travels along the length of the umbilicus 260 and endoscope shaft 100a to transmit light to the distal tip 100c of the endoscope 100. The connector portion 265 also connects the air pump 215 to the air supply line 240b in the umbilicus 260 when inserted into the video processing unit 210.
A water reservoir 270 (e.g., a water bottle) is fluidly connected to the endoscope 100 through the connector portion 265 and the umbilicus 260. A length of gas supply tubing 240c passes from one end in an air gap 275 positioned between the top 280 (e.g., a bottle cap) of the reservoir 270 and the remaining water 285 in the reservoir to a detachable gas/lens purge connection 290 external to the connector portion 265. The gas supply line 240b from the umbilicus 260 branches in the connector portion 265 to fluidly communicate with the gas supply piping 240c at the detachable gas/lens wash connection 290 and the gas pump 215. When the gas supply pipe 240c is on the connector portion 265, a length of lens wash pipe 245c, one end of which is positioned at the bottom of the reservoir 270, passes through the top 280 of the reservoir to the same detachable connection 290. In other embodiments, the connectors may be separate and/or apart from each other. The connector portion 265 also has a detachable irrigation connection 293 for an irrigation supply tubing (not shown) that runs from an irrigation water source (not shown) to the irrigation supply line 255b in the umbilicus 260. In some embodiments, the irrigation water is supplied via a pump (e.g., peristaltic pump) from a water source (not shown) separate from the water reservoir 270. In other embodiments, the lavage supply tubing and the lens wash tubing 245c may obtain water from the same reservoir. The connector portion 265 may also include a detachable suction connection 291 for fluidly connecting a vacuum source (e.g., hospital room suction) (not shown) to the suction supply line 250b and suction supply line 250a of the umbilicus 260 and endoscope 100.
The gas supply line 240b and the lens purge supply line 245b are fluidly connected to the valve well 135 of the gas/water valve 140 and are configured such that operation of the gas/water valve in the well controls the supply of gas or lens purge to the distal tip 100c of the endoscope 100. Suction supply line 250b is fluidly connected to valve well 135 for suction valve 145 and is configured such that operation of the suction valve in the well controls suction applied to working channel 235 of endoscope 100.
Referring to fig. 2, an exemplary operation of an endoscope system 200 including an endoscope, such as the endoscope 100 above, is explained. Air from the air pump 215 in the video processing unit 210 flows through the connection portion 265 and branches to the air/water valve 140 on the operating handle 115 through the air supply line 240b in the umbilical tube 260, and reaches the water reservoir 270 through the air supply pipe 240c via the connection 290 on the connector portion 265. When the air/water valve 140 is in the neutral position, air is allowed to flow from the valve to atmosphere if the user's finger is not on the valve. In the first position, the user's finger is used to block the vent to atmosphere. Gas is allowed to flow from the valve 140 along the gas supply line 240a and out the distal tip 100c of the endoscope 100, for example, to insufflate a treatment area of a patient. When the air/water valve 140 is depressed downward to the second position, the blocking air leaves the valve, allowing the pressure of the air passing from the air pump 215 to rise in the water reservoir 270. The supply of pressurized water forces water out of the lens wash tubing 245c, through the connector portion 265, the umbilicus 260, through the air/water valve 140, and along the lens wash supply line 245a, converging with the gas supply line 240a before exiting the distal tip 100c of the endoscope 100 via the gas/lens wash nozzle 220. The air pump pressure may be calibrated to provide lens washing water at a relatively low flow rate compared to the supply of washing water.
The magnitude of the flow rate of the lens wash is determined by the gas pressure in the water reservoir 270. When the gas pressure in the water reservoir 270 begins to drop, the air pump 215 replaces the lost air supply in the reservoir 270 as water is pushed out of the reservoir 270 through the lens wash tubing 245c to maintain a substantially constant pressure, which in turn provides a substantially constant lens wash flow rate. In some embodiments, a filter (not shown) may be placed in the path of the gas supply piping 240c to filter out unwanted contaminants or particulates from entering the water reservoir 270. In some embodiments, an outflow check valve or other one-way valve configuration (not shown) may be placed in the path of the lens wash supply tube to help prevent water from flowing back into the reservoir 270 after the water passes through the valve.
Irrigation water generally requires a relatively high flow rate compared to lens cleaning because the primary purpose is to remove debris in the treatment area within the patient that obstructs the user's view. Lavage is typically achieved using a pump (e.g., peristaltic pump), as described. In embodiments having a separate water source for irrigation, tubing placed at the bottom of the water source passes through the top of the water source and is threaded through the head on the upstream side of the pump. The piping 255c on the downstream side of the pump is connected to the lavage supply line 255b in the umbilicus 260 and the lavage supply line 255a of the endoscope 100 via the lavage connector 293 on the connector portion 265. When irrigation water is needed, fluid is pumped from the water source and flows through the irrigation connection 293 by operating the irrigation pump, such as depressing a foot switch (not shown), through the irrigation supply line 255b in the umbilicus and along the irrigation supply line in the shaft 100a of the endoscope to the distal tip 100c. To equalize the pressure in the water source as the water is pumped out of the lavage supply tube, a vent (not shown) may be included in the top 280 of the water reservoir 270. The vent holes allow atmospheric air to enter the water source, preventing negative pressure build-up in the water source, which may create a vacuum that draws unwanted substances from the patient's body through the endoscope toward the water source. In some embodiments, a configuration (not shown) similar to the outflow check valve or other one-way valve of the lens wash tubing 245c may be placed in the path of the lavage supply tubing to help prevent backflow of water into the reservoir after the water passes through the valve.
Fig. 3A-3D are schematic diagrams illustrating the operation of an embodiment of a mixing system 300 in which supply tubing for lavage and lens cleaning is connected to and aspirated from a single water reservoir. The mixing system 300 includes a single water reservoir 305, a cap 310 for the reservoir, a gas supply pipe 240c, a lens wash supply pipe 245c, an irrigation pump 315 having a foot switch 318, an upstream irrigation pipe 320, and a downstream irrigation supply pipe 255c. Cap 310 may be configured to be sealingly attached to water reservoir 305 by a typical threaded arrangement. The cap may include a gasket for sealing the cap 310 to the reservoir 305. The gasket may be an O-ring, flange, collar, etc. and may be formed of any suitable material. A plurality of through holes (325 a, 325b, 325 c) in the cap 310 are provided to receive the gas supply pipe 240c, the lens cleaning supply pipe 245c, and the upstream lavage supply pipe 320, respectively. In fig. 3A-3D, the system depicted includes separate tubing for gas supply, lens cleaning, and irrigation.
In other embodiments, the gas supply piping 240C and the lens cleaning piping 245C may be combined in a coaxial arrangement, as will be described in more detail below, such as described with respect to fig. 11A-11C and 14A-14B. For example, the gas supply tubing 240c may define a cavity of a diameter large enough to contain a smaller diameter lens wash tubing coaxially received in the gas supply tubing, and to provide air to a water source in an annular space around the lens wash tubing to pressurize the water reservoir (see, e.g., gas and lens wash supply tubing 240c, 245 c). The lens wash supply tubing may be configured in any suitable sealing manner, such as, for example, a bore, fitting, collar, etc. cavity defined by the coaxial gas supply tubing to transition from a coaxial arrangement to a side-by-side arrangement at a detachable gas/lens wash connection to an endoscope connector portion (e.g., connector portion 265 of fig. 2).
In various embodiments, different configurations of valves (not shown) may be incorporated into the various embodiments disclosed herein, including the piping of the systems 200, 300. For example, an inflow check valve may be provided in the path of the gas supply piping 240c to help prevent backflow into the gas pump 215. In this way, the pressure established in the water reservoirs 270, 305 creates a pressure differential between the water source and the gas supply piping 240c, helping to maintain a positive pressure in the water source, even when a large amount of water may be removed from the water source during the lavage function. This arrangement compensates for any time lag in the air delivered from the air pump 215 to the water reservoirs 270, 305, which would otherwise result in a negative pressure vacuum in the water reservoirs. Similarly, outflow check valves, such as one-way valves having inlet/outlet and valve inserts, may be incorporated into the lens wash supply piping 240c, the upstream lavage supply piping 320 and/or the downstream lavage supply piping 225c to help prevent backflow of water from either or both of the lens wash and lavage piping in the event of a negative pressure condition. One or more of these techniques are described in more detail below, such as described with respect to fig. 14A and 14B.
More generally, in many embodiments, a check valve may refer to any type of configuration that causes fluid to flow in only one direction in a passive manner. For example, the check valve may include or refer to one or more of a ball check valve, a diaphragm check valve, a swing check valve, a swash plate check valve, a flapper valve, a stop check valve, a lift check valve, a pass-through check valve, a duckbill valve, a pneumatic one-way valve, a reed valve, a flow check valve. Thus, a check valve as used herein is intended to be separate and distinct from an active valve (e.g., stop cock valve, solenoid valve, peristaltic pump) that operates in a binary manner as an on/off valve or switch to allow flow to be initiated or to allow flow to be closed.
During operation of the system of fig. 3A-3D, the flow of water for irrigation may be achieved by operating the irrigation pump 315. The water flow for lens cleaning may be achieved by depressing a gas/water valve 140 on the operating handle 115 of the endoscope 100. These functions may be performed independently of each other or simultaneously. When lens washing and lavage are operated simultaneously, when fluid is removed from the water reservoirs 270, 305, the pressure in the system can be controlled to maintain the lens washing supply piping 240c substantially at the pressure required to achieve a lower flow rate of lens washing while compensating for the pressure drop in the water reservoirs 270, 305 due to the supply of a high flow rate lavage. When the pressure in the water reservoir is reduced by using the lens washing function, the lavage function, or both, the reduced pressure can be compensated for by the air pump 215 via the gas supply pipe 240 c.
The schematic arrangement in fig. 3A to 3D has been highlighted to show different flow paths with a mixing system 300, the mixing system 300 having supply piping for lavage 320 and lens cleaning 240c connected to and aspirated from a single water reservoir 305. As shown in fig. 3A, endoscope 100 is in a neutral state with air/water valve 140 in an open position. The neutral state delivers neither gas to the distal tip of the endoscope nor lens cleaning. Conversely, gas (pressure) is delivered from the pressurized air pump 215 along path a and is exhausted to atmosphere via connector portion 265 through gas supply line 240b in umbilicus 260 and through the gas/water valve. Since the system is open at the vent hole in the air/water valve 140, there is no accumulation to pressurize the water reservoir 305 and thus no pushing of water through the lens wash supply pipe 240c.
As shown in fig. 3B, the endoscope 100 is in a gas delivery state with the gas/water valve 140 in a first position. When gas is needed at the distal tip 100c, for example, to clean the end face 100d of the distal tip or to blow the patient's body in the treatment area, the user closes the vent in the gas/water valve 140 with a thumb, finger, or the like (first position). At this stage, gas (pressure) is delivered from the air pump 215 along path B and flows through the gas supply line 240B in the umbilicus 260 via the connector portion 265. The gas continues through the gas/water valve 140 to the gas supply line 240a in the endoscope shaft 100a and exits the gas/lens cleaning nozzle 220 at the distal tip 100 c. Since the system is open at the air/lens water nozzle 220, there is no accumulation to pressurize the reservoir, and therefore no water is pushed through the lens wash supply pipe 240c.
As shown in fig. 3C, endoscope 100 is in a lens wash delivery state with air/water valve 140 in a second position. When lens cleaning is required at distal tip 100c, for example, to clean end face 100d of distal tip 100c, the user holding the vent in the air/water valve closed depresses valve 140 to its furthest point in valve well 135. The second position blocks the supply of gas to atmosphere and gas supply line 240a in the endoscope and opens gas/water valve 140 to allow lens wash water to pass through to lens wash supply line 245a in endoscope shaft 100a and out of gas/lens wash nozzle 220 at distal tip 100 c. In this state, the gas (pressure) is sent from the gas pump 215 along the path C, passes through the branch line in the connector portion 265, and leaves the gas supply piping 240C to the water reservoir 305. The gas (pressure) pressurizes the surface of the remaining water 285 in the reservoir 305 and pushes the water up the lens wash supply tube 245c to the connector portion 265. The pressurized lens wash water is further pushed through the lens wash supply line 245b in the umbilicus 260 and through the air/water valve 140. Since the system 300 is closed, the gas pressure is allowed to build up and maintain a calibrated pressure level in the water reservoir 305, rather than venting to atmosphere or being delivered to the patient. This pressure, along with the endoscope supply and supply lines and external tubing, translates into a range of lens cleaning flow rates.
As shown in fig. 3D, the endoscope 100 is in an lavage delivery state. This may be performed at the same or different time as the delivery of the gas and/or lens purge. When irrigation is desired at the distal tip 100c, for example, if visibility in the treatment area is poor or blocked by debris, etc., the user activates the irrigation pump 315 (e.g., by depressing the foot switch 318) to deliver water along path D. Upon activation of the pump 315, water is drawn out of the water reservoir 305 through the upstream lavage supply tubing 320 and pumped along the downstream lavage supply tubing 255c to the connector portion 265. The irrigation pump head pushes irrigation water further through the irrigation supply line 255b in the umbilicus 260, through the irrigation supply line 255a in the endoscope shaft 100a, and out the irrigation opening 225 at the distal tip 100 c. The lavage pump pressure can be calibrated, along with the endoscope lavage supply and supply lines and external tubing, to deliver a range of lavage fluid flow rates.
FIG. 4 is a schematic diagram illustrating another embodiment of a hybrid system 400, the hybrid system 400 including video processingUnit 210, connector portion 265, peristaltic lavage pump 315, water reservoir 405 and top 407, coaxial gas and lens wash supply tubing 410, upstream and downstream lavage supply tubing 320, 255c, and replacement gas supply tubing 415 (e.g., CO 2 ). A length of replacement gas supply piping 415 passes from one end in an air gap 275 between the top 407 of the water reservoir 405 and the remaining water 285 in the reservoir through an additional opening 420 in the top of the reservoir to a supply of replacement gas (e.g., CO 2 Hospital gas source) and a detachable connection 425. When an alternative gas supply is required, such as CO 2 When gas is present, the gas pump 215 on the video processing unit 210 may be turned off and the CO 2 Gas, rather than air, flows from there to the water reservoir 405, pressurizing the surface of the water. In the neutral state, CO 2 The gas flows back up the gas supply pipe 240c to the connector portion 265, up the gas supply line 240b and is exhausted to atmosphere through the gas/water valve 140. In the first position, the user closes the vent in the air/water valve 140 and the CO 2 The gas flows through the gas/water valve to the gas supply line 240a in the endoscope shaft 100a and out the gas/lens cleaning nozzle 220 at the distal tip 100 c. In the second position, the user depresses the valve 140 to the bottom of the valve well 135, thereby keeping the vent hole in the air/water valve closed. The second position blocks CO to atmosphere and to the gas supply line 240a in the endoscope 100 2 The gas is supplied and the gas/water valve 140 is opened to allow the lens wash water to pass through to the lens wash supply line 245a in the endoscope shaft 100a and out of the gas/lens wash nozzle 220 at the distal tip 100 c. The gas (pressure) in the reservoir 405 is replaced by a gas (e.g., CO 2 ) The transport gas of the supply pipe 415 is maintained. The lavage function may be implemented in a similar manner as described above with respect to fig. 3D.
In accordance with the principles of the present invention, and with reference to fig. 5-11C and 14-15, in one embodiment, a water reservoir, bottle, container, etc. (such terms are used interchangeably and are not intended to limit or otherwise convey different meanings or intents) and a tubing assembly or set (such terms are used interchangeably and are not intended to limit or otherwise convey different meanings or intents) may be integrally formed such that the water container and one or more tubes are permanently and inseparably coupled to one another (e.g., the tubes cannot be disconnected from the container (e.g., caps of existing devices are eliminated)). Collectively referred to herein as an integrated vessel and tube set. It should be appreciated that one or more tubes of the integrated container and tube set may be removably coupled to the container without departing from the scope of the invention.
In an embodiment formed in accordance with the principles of the present invention, a container and tube set are combined into an integrated container and tube set, wherein one or more of the tubes are combined or merged with a container filled with a fluid, such as H 2 O and air, such as, for example, air, CO 2 Etc. For example, in one embodiment, the container and tube may be formed or molded simultaneously. Alternatively, in one embodiment, the tube may be initially formed or molded, and the container may be formed or molded around the tube, to the tube, or the like. The integrated container and tube set may then be filled with water and sealed to create a sterile container for use in endoscopic surgery. Such an arrangement provides an improved fluid and gas container that reduces the likelihood of infection. In addition, the integrated container and tube set provides more flexibility and fewer parts to the manufacturer. In one embodiment, the integrated container and tube set may be configured as a single-use item (e.g., a disposable single-use item intended to be discarded after use), however in one embodiment the integrated container and tube set may be refillable and thus reusable. In one embodiment, the integrated container and tube set may be provided in an off-the-shelf sterile container to supply fluids and/or gases to the endoscope during endoscopic surgery.
In one embodiment, the integrated container and tube set may replace (e.g., replace) the water reservoir and cap of the system described above in connection with fig. 1-4. That is, during use, the integrated container and tube set may be used in conjunction with (e.g., coupled to) an endoscope to supply fluid and/or gas to the endoscope, for example, for lavage, lens cleaning, and insufflation during endoscopic procedures. For this purpose, inIn one embodiment, the integrated water reservoir and tube set includes a plurality of tubes (e.g., lumens) for supplying fluid (e.g., water) and/or gas (e.g., CO) to the endoscope 2 Air, etc.) to accommodate various endoscopic procedures as previously described. For example, in one embodiment, the integrated container and tube set may include a first lavage supply tube, a second lens wash supply tube, and a third gas supply tube. Further, the integrated vessel and tube set may include a fourth alternative gas supply tube. So arranged, as previously described in connection with fig. 1-4, upon actuation of the endoscope system, the integrated container and tube set may be arranged and configured to (i) supply a gas (e.g., air or CO 2 ) To blow the patient; (ii) Supplying fluid to flush or clean the lens of the endoscope, and (iii) supplying fluid to perform irrigation (e.g., perform flushing and/or aspiration of the working channel). During use, as previously described in connection with fig. 1-4, depending on the user's manipulation of valves and other corresponding foot pedals and connectors on the endoscope, the delivery of fluid or gas to the endoscope is provided in a desired manner (e.g., supplying high pressure/volume of fluid for lavage, supplying fluid for lens cleaning, or supplying air/gas for insufflation of the patient).
Aspects of the present invention may result in a more efficient and/or environmentally friendly endoscope system in many embodiments formed in accordance with the principles of the present invention. In several embodiments, integrating the container and tube set may reduce waste, such as by facilitating reusability. For example, a fill port may be included to replenish the liquid supply in the container. The fill port may additionally allow for the use of different fluids, such as to support multiple endoscopic procedures. In some embodiments, integrating the containers and the tube sets may reduce the associated logistics and storage costs. For example, the integrated container may be collapsible to reduce the volume required to store or package the integrated container and tube set. In various embodiments, integrating the container and tube set may reduce manufacturing complexity. For example, integrally forming one or more components may reduce assembly steps. In many embodiments, the integrated container and tube set may include a container having one or more interfaces configured to enable the container to be used in connection with various systems and configurations. In various embodiments, the components of the integrated container and tube set may include features for reducing cleaning and/or treatment time (such as between procedures). For example, the coaxial tubing may reduce the amount of surface area that must be cleaned. Additionally or alternatively, the integrated container and tube set may include a container designed and shaped to improve efficiency and flexibility. For example, the container may include features, such as a neck at the gas tubing connection port, to reduce or prevent flow of liquid into the gas tubing. In another example, the container may be designed such that the irrigation supply tubing is coupled at a lower point of the reservoir, such as to facilitate the flow of liquid from the container to the irrigation supply tubing.
Additionally and/or alternatively, in one embodiment, each of the tubes may be sealed to maintain a sterile environment (e.g., to seal the container and tube) prior to use. Additionally and/or alternatively, each of the tubes may include, for example, a one-way valve to prevent backflow into the container during use. For example, in one embodiment, each of the tubes may include a one-way valve in the second end of the tube to prevent backflow of fluid into the container during use. Additionally and/or alternatively, one or more of the tubes may include a connector or adapter, such as, for example, a Tuohy Borst connector, an adjustable connector, such as, for example, a stop-cock adapter, a split connector, such as, for example, a coaxial split connector or a mirror adapter, arranged and configured to couple to an endoscope or the like. In use, the adapter may be arranged and configured in a normally closed position to maintain a sterile environment prior to use. After that, during use, a user may move one or more of the adapters from the closed position to the open position as desired to enable fluid and/or gas to flow as desired.
Turning now to the drawings, various embodiments of integrated containers and tubing sets are shown for use with the disclosed and described information examples and are not intended to limit the invention in accordance with the broad principles described herein. Fig. 5-7 illustrate one embodiment of an integrated container and tube set 500 formed in accordance with various principles of the present invention. As previously mentioned, the integrated container and tube set 500 may be used in place of the water reservoir 270 (e.g., water bottle) described above in connection with fig. 1-4. As shown in fig. 5-7, the integrated container and tube set 500 includes a container (e.g., water bottle, reservoir, etc.) 520 and a plurality of tubes 530 associated with the container 520. In one embodiment, each of the plurality of tubes 530 includes an outer wall that is continuous with the container 520. That is, the plurality of tubes 530 may be integrally formed with the container 520 (e.g., the tubes 530 may be permanently and inseparably molded to the container 520 such that there is no interconnected removable cap between the tubes and the container, such as, for example, caps or tops 280, 310).
In one embodiment, as shown, the container 520 may be arranged and configured as a rigid (e.g., incompressible) container made of any suitable material now known or later developed, including, for example, plastic, elastomer, etc. As shown, the container 520 may have a generally rectangular shape, however this is only one configuration, and the container 520 may have other shapes, such as, for example, square, cylindrical, etc. The container 520 includes a bottom 522 arranged and configured to hold, receive, store, etc., a fluid, such as, for example, H 2 O; and a top (e.g., air gap) 524 arranged and configured to hold, receive, store, etc. a gas, such as, for example, air, CO 2 Etc., such that fluid or gas may be supplied to the endoscope as desired, depending on the operation of the endoscope as previously described, including, for example, actuation of the endoscope valve and/or foot pedal by a user.
According to aspects of the present invention and as previously mentioned, the tube 530 may be integrally formed with the container 520 such that the container 520 and the tube 530 may be provided as a single fluid delivery device. The integrated container and tube set 500 may be integrally formed by any suitable method now known or later developed. For example, in one embodiment, the tube 530 may be formed simultaneously with the container 520 using, for example, a moldable plastic, elastomer, or the like. For example, the container 520 may be molded to each of the plurality of tubes 530. Alternatively, the tube 530 may be formed initially and the container 520 may then be molded around the pre-existing tube 530, thereby creating an integral assembly. In this way, the tube 530 may be made of a different material than the container 520.
In either case, once properly manufactured, the integrated container and tube set 500 may be filled with a fluid, such as, for example, H, in its bottom 522 2 O and is filled with a gas, such as, for example, air, in its top 524. The integrated container and tube set 500 may then be sealed or capped. In one embodiment, the container 520 may be filled using one or more of the manifold 530 (e.g., a fluid and/or gas may be inserted into the container 520 through the second end of the manifold 530). Alternatively, in one embodiment, the container 520 may include a supply port 526 (fig. 3) for injecting fluid therein. That is, in one embodiment, the container 520 may include a supply port 526, such as, for example, in a bottom surface thereof, that is arranged and configured to couple with a fluid supply to supply fluid into the container 520. In either case, the integrated container and tubing set 500 may then be sealed or capped and subsequently sterilized, thereby creating a sealed integrated sterile container and tubing set 500 (e.g., sealing the fluid from the surrounding atmosphere). That is, as will be described in more detail below, each of the tubes 530 may be sealed or capped to prevent air or the like from entering the integrated container and tube set 500.
As previously mentioned, the integrated container and tubing set 500 may include a plurality of tubes 530. For example, referring to fig. 5 and 7, in one embodiment, the integrated container and tubing set 500 may include first, second, third, and fourth tubes 540, 550, 560, 570, however this is only one configuration and more or fewer tubes may be provided, such as one, two, three, etc., depending on the medical procedure being performed. As shown, the first tube 540 may include a first end 542, a second end 544, and a first cavity 546 extending from the first end 542 to the second end 544. As previously mentioned, in one embodiment, the first tube 540 is integrally formed with the container 520 (e.g., the first tube 540 includes an outer wall that is continuous with the container 520). In the case where the first tube 540 passes through the container 520, the first tube 540 Is disposed and configured to be in fluid communication with the bottom 522 of the container 520, while the second end 544 of the first tube 540 is disposed and configured to extend outwardly from the container 520 such that the second end 544 is positioned outside of the container 520. So arranged, the first tube 540 is arranged and configured to supply fluid to the endoscope. In one embodiment, as described above in connection with fig. 1-4, the first tube 540 may be arranged and configured to be operably coupled to a pump (e.g., a peristaltic pump) such that fluid may be drawn from the container 520 to provide irrigation (e.g., a lower pressure, higher volume of water may be provided by drawing water from the container 520 with the pump). That is, the second end 544 of the first tube 540 can be operably coupled to a pump (e.g., peristaltic pump) such that the first lumen 546 is arranged and configured to be fluidly coupled to an irrigation channel of an endoscope to provide fluid (e.g., H 2 O) is supplied from the container 520 to the lavage channel of the endoscope. In this manner, the first tube 540 may also be referred to as an lavage supply tube.
In one embodiment, the integrated container and tube set 500 may further include a second tube 550 including a first end 552, a second end 554, and a second lumen 556 extending from the first end 552 to the second end 554. As previously mentioned, in one embodiment, the second tube 550 is integrally formed with the container 520 (e.g., the second tube 550 includes an outer wall that is continuous with the container 520). With the second tube 550 passing through the container 520, the first end 552 of the second tube 550 is disposed and configured to be in fluid communication with the bottom 522 of the container 520, while the second end 544 of the second tube 550 is configured to extend outwardly from the container 520 such that the second end 544 of the second tube 550 is positioned outside of the container 520. So arranged, the second tube 550 is arranged and configured to supply fluid to the endoscope. In one embodiment, as described above in connection with fig. 1-4, depending on the surgeon's actuation of various valves on the endoscope, the second tube 550 may be arranged and configured to wash, clean, etc., the lens of the endoscope (e.g., to provide fluid across the imaging lens of the endoscope). In this way, the second tube 550 may also be referred to as a lens cleaning supply tube.
In one embodiment, the container and tube set are integrated500 may also include a third tube 560 including a first end 562, a second end 564, and a third cavity 566 extending from the first end 562 to the second end 564. As previously mentioned, in one embodiment, the third tube 560 is integrally formed with the container 520 (e.g., the third tube 560 includes an outer wall that is continuous with the container 520). With the third tube 560 passing through the container 520, the first end 562 of the third tube 560 is disposed and configured to be in operable communication with the top 524 of the container 520, and the second end 564 of the third tube 560 is disposed and configured to extend outwardly from the container 520 such that the second end 564 is positioned outside of the container 520. So arranged, the third tube 560 is arranged and configured to supply air to the endoscope. For example, in one embodiment, as described above in connection with fig. 1-4, the third tube 560 may be operably coupled to a pump (e.g., an air pump). In one embodiment, the third tube 560 may be arranged and configured to work in conjunction with the second tube 550. That is, depending upon, among other things, the surgeon's actuation of a valve on the endoscope, air may be supplied from the pump to the reservoir 520 via the third tube 560 to pressurize the reservoir 520 to push fluid through the second lumen 550 to the lens wash. Alternatively, air may be supplied from the pump to the endoscope via the third tube 560 to insufflate the patient with air, depending inter alia on the surgeon's actuation of a valve on the endoscope. Thus, in one configuration, in use, the second and third tubes 550, 560 (e.g., the second and third chambers 556, 566) may be used to pressurize the container 520 with air to force the fluid (H 2 O) is supplied to the endoscope for cleaning the lens (e.g., lens cleaning). Alternatively, in another configuration, in use, the third tube 560 (e.g., the third lumen 566) may be used to supply air to the patient for insufflation. So arranged, the third tube 560 may be referred to as a gas supply tube.
In one embodiment, as best shown in fig. 7, the second or lens wash supply tube 550 and the third or gas supply tube 560 (e.g., second and third lumens 556, 566) may be combined into a single multi-lumen tube. So arranged, in one embodiment, the second chamber 556 may be coaxial with the third chamber 566. For example, the second chamber 556 may be disposed or positioned within the third chamber 566. Alternatively, however, the second and third cavities 556, 566 may be disposed adjacent to one another, for example, in side-by-side relationship. For example, in one embodiment, the multi-lumen tube may include an inner wall extending along its length between the second lumen 556 and the third lumen 566.
So arranged, the second lumen 556 is arranged and configured to extend from the second end of the multi-lumen tube to the first end of the multi-lumen tube such that the second lumen 556 is arranged and configured to be in fluid communication with the bottom 522 of the container 520. The third lumen 566 is arranged and configured to extend from the second end of the multi-lumen tube toward the first end of the multi-lumen tube. However, the third cavity 566 is disposed and configured in operative communication with the top 524 of the container 520 (e.g., the third cavity 566 does not extend longitudinally as far into the container 520 as the second cavity 556).
With continued reference to fig. 5-7, in one embodiment, the integrated container and tubing set 500 may further include a fourth tube 570 having a first end 572, a second end 574, and a fourth chamber 576 extending from the first end 572 to the second end 574. As previously mentioned, in one embodiment, the fourth tube 570 is integrally formed with the container 520 (e.g., the fourth tube 570 includes an outer wall that is continuous with the container 520). With the fourth tube 570 passing through the container 520, a first end 572 of the fourth tube 570 is disposed and configured to be in operable communication with the top 524 of the container 520, and a second end 574 of the fourth tube 570 is disposed and configured to extend outwardly from the container 520 such that the second end 574 is positioned outside the container 520.
In use, in one embodiment and as described above in connection with fig. 1-4, the fourth lumen 576 can be arranged and configured to cooperate with the third lumen 566. For example, in one embodiment, the fourth chamber 576 may be operatively coupled to a gas source such as, for example, CO with the pump coupled to the gas supply tube 560 turned off 2 A source. Thereafter, in the case where the air pump is turned off, CO can be supplied 2 From CO via fourth pipe 570 2 The source is supplied to the vessel 520 to use CO 2 Pressurizing the vessel 520, CO 2 Can then be supplied to the endoscope via the gas supply tube 560 to enable CO 2 Through an endoscope into a target space in a controlled mannerBy CO 2 Insufflating a patient (e.g., CO with a pump coupled to the gas supply tube 560 in a closed position) 2 Can be derived from CO via fourth pipe 570 2 The source is supplied to the vessel 520, which pressurizes the vessel 520, resulting in CO 2 Is supplied to the endoscope via a third or gas supply tube 560). So arranged, the fourth tube may be referred to as a substitute gas supply tube (e.g., CO 2 )。
With continued reference to fig. 5-7 and as will be described in greater detail below, in one embodiment, each of the plurality of tubes 530 may be sealed, capped, etc. to maintain a sterile environment prior to use. For example, each of the plurality of tubes 530 may include a seal 580 formed in or along its second end to prevent fluid, moisture, air, etc. from entering the container 520. Additionally, one or more tubes of other embodiments, such as those described with respect to fig. 11A-11C and/or 14A-14B, may incorporate one or more of the aspects and/or components to maintain a sterile environment without departing from the invention.
Additionally and/or alternatively, each of the plurality of tubes 530 may include, for example, a one-way valve 585 in a second end thereof. In use, the one-way valve 585 prevents backflow of fluid into the container 520. That is, incorporating the check valve 585 into each of the second ends 544, 554, 564, 574 of the first, second, third and fourth tubes 540, 550, 560, 570 ensures that the tubes are sealed from the surrounding environment, thereby ensuring that the container 520 remains sterile until operation. In one embodiment, the check valve 585 may take the form of, for example, a Tuohy Borst adapter. In one embodiment, as will be described in greater detail below, in use, the check valve 585 may be arranged and configured to puncture or pierce a seal 580 formed in the tube 530 when the check valve 585 is coupled thereto. For example, the one-way valve 585 may include a piercing or piercing member for piercing the seal 580. So arranged, in use, the coupling of the one-way valve 585 to the second ends 544, 554, 564, 574 of the first, second, third and fourth tubes 540, 550, 560, 570 pierces a seal 580 formed in the tubes.
Additionally and/or alternatively, as shown, the second end of one or more of the plurality of tubes 530 may include, for example, an adapter, connector, or the like 588 coupled directly or indirectly to the second end thereof via, for example, a one-way valve 585. That is, in one embodiment, the adapter 588 may be directly coupled to one or more of the second ends of the tubes. Alternatively, in one embodiment, the adapter 588 may be coupled to one or more of the check valves 585, which may be coupled to one or more of the second ends of the tubes. In one embodiment, in use, the adapter 588 may be arranged and configured to puncture or pierce a seal 580 formed in the tube 530 when directly coupled thereto. For example, the adapter 588 may include a piercing or piercing member for piercing the seal 580. So arranged, in use, the coupling of the adapter 588 to the second end of the tube may pierce a seal 580 formed in the tube.
In one embodiment, the adapter 588 may take the form of, for example, an adjustable connector. For example, in one embodiment, as shown, the adapter 588 may take the form of a stop-cock adapter. In use, the stop-cock adapter may be directly or indirectly coupled to the second end of one or more of the tubes 530. For example, as shown, in use, the replacement gas supply tube 570 may comprise a shut off tap adapter. In use, the shut off tap adapter may be manipulated by a user from a closed position to an open position. So arranged, a user may enable gas and/or fluid to flow through the respective tube by manipulating the stop-cock adapter between the closed and open positions. For example, in connection with the illustrated embodiment, a user may move the stop-cock adapter from a closed position to an open position to allow a gas (e.g., CO 2 ) Can be supplied from CO via a substitute gas supply pipe 570 2 A source fluid is flowed into vessel 520 to pressurize vessel 520.
Alternatively, in one embodiment, the adapter 588 may be in the form of a coaxial split connector 590 directly or indirectly coupled to a tube. For example, in connection with the illustrated embodiment, the coaxial split connector 590 may be coupled directly or indirectly to the second end of the multi-lumen tube (e.g., the lens wash supply tube 550 and the gas supply tube 560) such that the second and third lumens 556, 566 may be coupled to the endoscope via the coaxial split connector 590. So arranged, in use, the coaxial disconnect connector 590 is arranged and configured to be coupled to an endoscope such that fluids and gases may be exchanged with the endoscope. For example, in one embodiment, the coaxial split connector 590 may be arranged and configured to supply fluid and/or gas from the container 520 to the endoscope via the second and third lumens 556, 566, however this is only one configuration. In one embodiment, the coaxial split connector 590 may be arranged and configured as, for example, a T-connector. The coaxial split connector 590 may be arranged and configured as a flexible or plastic end connector to enable the second end of the tube to be coupled to, for example, an endoscope, a gas source, etc., as desired. Alternatively, in one embodiment, the coaxial split connector 590 may be overmolded onto a tube or the like.
Thereafter, in use, the integrated container and tube set 500 is coupled to an endoscope, a gas (CO) 2 ) In the case of sources, air pumps, etc., the surgeon may operate, open, etc., one-way valves, etc., to allow fluid and/or gas flow. Subsequently, when needed by the endoscope (e.g., when the surgeon actuates one or more of the various valves on the endoscope, as described above in connection with fig. 14), fluid and/or gas may be supplied to the endoscope, depending on the procedure being performed.
Referring to fig. 8A, an alternative embodiment of an integrated container and tubing set 600 is disclosed. In accordance with one or more aspects of the present invention, the integrated container and tube set 600 is substantially similar to the integrated container and tube set 500 disclosed above in connection with fig. 4-7, except as outlined herein. Accordingly, a detailed description of similar elements is omitted herein for brevity.
In accordance with one or more aspects of the present invention, the integrated container and tube set 600 includes a container 620 and a plurality of tubes 630. However, in contrast to the container 520 described above in connection with fig. 5-7, the container 620 may be arranged in a non-rigid configuration (e.g., the container 620 may be arranged and configured as a compressible container). For example, the container 620 may take the form of a bag, pouch, or other soft fluid container similar to a saline bag (such terms may be used interchangeably and are not intended to be limiting or otherwise convey a different meaning or intent). So arranged, the non-rigid container 620 may be referred to herein as a bag. According to this embodiment, tube 630 may be molded to bag 620 while bag 620 is being manufactured. So arranged, the pouch 620 and tube 630 may be fabricated from a suitable homogeneous material, including, for example, plastic, elastomer, or any other suitable material now known or later developed. Alternatively, in one embodiment, the pocket 620 may be formed separately from the tube 630. For example, in one embodiment, tube 630 may be formed, and bag 620 may be subsequently molded around tube 630. So arranged, a composite assembly can be manufactured. In this embodiment, the bag 620 and tube 630 may be made of a suitable uniform material. Alternatively, the pouch 620 and tube 630 may be manufactured from different materials.
Alternatively, referring to fig. 8B, in one embodiment, tube 630 may be manufactured separately from bag 620. That is, the tube 630 may be reversibly coupled to the bag 620 (e.g., the tube 630 is arranged and configured to be inserted into the bag 620 and may be removable therefrom in one embodiment). For example, in one embodiment, each of the tubes 630 may include a first end 632 that includes a piercing or penetrating member 634 arranged and configured to pierce a film or surface of the bag 620 when the tube 630 is inserted, pressed, etc. into the bag 620 to enable fluid and/or gas flow, as previously described. That is, in use, the first end 632 of the tube 630 may include a piercing or penetrating member 634, such as, for example, a sharpened tip or the like. So arranged, in use, an operator may insert one or more tubes 630 into the pocket 620 to supply fluid and/or gas to the endoscope as desired.
Additionally and/or alternatively, in one embodiment, the plurality of tubes 630 may be arranged and configured as multi-lumen tubes. For example, the first lavage supply tube, the second lens wash supply tube, the third gas supply tube, and the optional fourth substitute gas supply tube may be arranged and configured as a single tube at least along a first end thereof (e.g., walls of each of the tubes may be coupled to each other or integrally formed with each other). Alternatively, the first lavage supply tube, the second lens wash supply tube, the third gas supply tube, and the optional fourth substitute gas supply tube may be formed separately and coupled together, or may remain separate and distinct from each other.
In accordance with one or more aspects of the present invention, the bag 620 may be filled during a molding operation or a post-molding operation. Thereafter, similar to the integrated container and tube set 500 previously described, the bag 600 including the container 620 and tube 630 may be used in place of the water reservoir 270 (e.g., a water bottle) described above in connection with fig. 1-4.
Referring to fig. 9-10B, an alternative embodiment of an integrated container and tube set 700 is disclosed. In accordance with one or more aspects of the present invention, the integrated container and tube set 700 is substantially similar to the integrated container and tube set 500 disclosed above in connection with fig. 4-7, except as outlined herein. Accordingly, a detailed description of similar elements is omitted herein for brevity.
In accordance with one or more aspects of the present invention, the integrated container and tube set 700 includes a container 720 and a plurality of tubes 730. As shown, each of the tubes 730 may include a first end 732 disposed within the container 720 and a second end 734 positioned outside of the container 720. In accordance with one or more aspects of the present invention, the second end 734 of the tube 730, such as, for example, the second ends of the first lavage supply tube, the second lens wash supply tube, the third gas supply tube, and the optional fourth substitute gas supply tube, can be capped, closed, sealed, etc. 780 (such terms can be used interchangeably, without intending to limit or otherwise communicate different meanings or intentions) during manufacture to create a permanently sealed assembly. Thereafter, in use, the second end 734 of the tube 730 may be pierced by, for example, a piercing or penetrating member. For example, in one embodiment, the piercing or penetrating member may take the form of one or more of a one-way valve, a connector, a coaxial split connector, etc., coupled to the second end 734 of the tube 730. For example, in one embodiment and as schematically illustrated in fig. 10A and 10B, the coaxial split connector 590 may be arranged and configured to pierce or penetrate the sealing portion when the coaxial split connector 590 is coupled to the second end 734 of the tube.
The capping or sealing portion 780 may be configured along any length of the tube 730. For example, in one embodiment and as generally shown, the capping or sealing portion 780 may be positioned near an end of the second end 734 of the tube 730 or at some point inside the tube 730. In use, the valve, connector, adapter, etc. may be arranged and configured to be coupled to the tube 730 via any suitable mechanism or method now known or later developed. For example, a valve, connector, or adapter may be press fit onto tube 730. Alternatively, anchoring methods may be utilized, such as luer fittings, threaded connections, and the like. In either event, once coupled to the tube 730, the valve, connector, or adapter is arranged and configured to create a seal with the tube 730 to prevent leakage at the puncture point.
Referring to fig. 11A-11C, various embodiments of an integrated container and tube set 1100A, 1100B, 1100C are disclosed. According to one or more aspects of the present invention, the integrated vessel and tube set 1100A, 1100B, 1100C may be substantially similar to the integrated vessel and tube set 500, 600, 700, 1400A, 1400B disclosed in connection with fig. 4-10A and 14A-14B, except as outlined herein. Similarly, in accordance with one or more aspects of the present invention, one or more components or features of integrated container and tube sets 1100A, 1100B, 1100C may be substantially similar to one another, except as outlined herein. Accordingly, a detailed description of similar elements may be omitted herein for brevity.
In general, fig. 11A-11C illustrate an integrated vessel and tube set (i.e., 1100A, 1100B, or 1100C) that includes a gas/lens purge connection 1190, a coaxial tubing 1110, a vessel (i.e., 1120A, 1120B, or 1120C), an upstream lavage supply tubing 1119, a lavage pump 1115, a downstream lavage supply tubing 1155C, a lavage connection 1193, a substitute gas supply tubing 1170, and a substitute gas connection 1125. Some embodiments may not include an alternative gas supply piping 1170 or an alternative gas connection 1125 (see, e.g., fig. 11C). As shown in fig. 11A and 11B, a gas/lens purge connection 1190 and an lavage connection 1193 may be removably coupled to the connector portion 1165.
In many embodiments, connector portion 1165 may be the same as or similar to connector portion 265, such as shown in fig. 2 and 4. In some embodiments, the gas/lens purge connection 1190 may include a coaxial split connector having first and second openings. In some such embodiments, the first opening is in fluid communication with an inner tube of the coaxial tube (e.g., lens wash supply piping 1145 c) and the second opening is in fluid communication with an outer tube of the coaxial tube (e.g., gas supply piping 1140 c).
In fig. 11A, a container 1120a may include an upper half 1143a, a lower half 1147a, and an interface 1160a, 1160b. In fig. 11B, the container 1120B may include an upper half 1143B, a lower half 1147B, and interfaces 1171a, 1171B. In fig. 11C, the container 1120C may include an upper half 1143C, a lower half 1147C, and an interface 1180. More generally, the upper half of the container may include a fill port 1102. In many embodiments, the fill port 1102 may be resealable. For example, the fill port 1102 may include a removable cap or an openable valve. In some embodiments, the fill port 1102 may include a check valve, such as in a removable cap. More generally, in various embodiments, a check valve may be included in the upper half of a container configured to be equal to atmospheric pressure. For example, when a rigid container is utilized, a check valve may be included to prevent or limit negative pressure differential to the atmosphere. A coaxial tubing 1110 and a replacement gas supply tubing 1170 may be coupled to the upper half. In many embodiments, the outer tube of the coaxial tubing 1110 (e.g., gas supply tubing 1140 c) may be coupled to and terminate in the upper half of the container (e.g., 1143a of fig. 11A), while the inner tube of the coaxial tubing 1110 (e.g., lens wash tubing 1145 c) may extend to and terminate in the lower half of the container (e.g., 1147a of fig. 11A).
In various embodiments, one or more portions of the coaxial tubing 1110 and/or the replacement gas supply tubing 1170 may be integrally formed with the container. An upstream lavage supply tube 1119 can be coupled to the lower half. In some embodiments, one or more portions of the irrigation supply tubing may be integrally formed with the containers 1120a, 1120b, 1120 c.
The liquid in the bottom 1122 of the container may flow into the upstream lavage supply tube 1119 or the lens wash tube 1145 c. In many embodiments, gas may be introduced into the top 1124 of the container, such as via gas supply tubing 1140c or alternative gas connection 1125, to force liquid into the lens wash tubing 1145 c. In some embodiments, irrigation pump 1115 may be used to draw liquid from the container via upstream irrigation supply tubing 1119 and pump liquid to irrigation connection 1193 via downstream irrigation supply tubing 1155 c. In many embodiments, the lavage pump 1115 can comprise a peristaltic pump. In some embodiments, the upstream lavage supply tube 1119 may be more rigid or stronger than the downstream lavage supply tube. For example, the upstream lavage supply tubing may be more resistant to collapse than the downstream lavage supply tubing.
Referring specifically to fig. 11A, the container 1120a may be shaped such that the upstream lavage supply tubing is coupled to the container at a lowest point. The reservoir 1120a may also include a downward wedge shape to facilitate fluid flow into the lavage supply tubing. In some embodiments, the container 1120a may include a width that is greater than its depth. For example, the width may be selected to match the width of another component (e.g., an lavage pump, video processing unit, or cart) and a narrower profile to provide an efficient and space-saving construction. In many embodiments, the container shape is selected based on the component or components to which the interface is configured to be coupled. The container 1120a may include one or more interfaces to couple with one or more of a stand, cradle, and rest. For example, the interfaces 1160a, 1160b may comprise flat hooks that may be coupled to another component, such as a pump, video processing unit, or cart.
Additionally, the container 1120a may include a neck where the gas supply tubing 1140c and the alternative gas supply tubing 1170 are coupled to the container 1120a. In various embodiments, the neck may reduce or prevent liquid 1122 from flowing from the container 1120a into the gas supply tubing 1140c and the replacement gas supply tubing 1170. In some embodiments, the container 1120a may be made of a rigid material. In another embodiment, the container 1120a may be made of a flexible material. In another such embodiment, the container 1120a may be collapsible. In many embodiments, the neck may be made of a material that is more flexible than the rest of the container 1120a.
Referring specifically to fig. 11B, the container 1120B may include one or more interfaces to couple with one or more of a stand, cradle, and rest. For example, the interfaces 1171a, 1171b may include a ring or handle that may be used to hang the container 1120b, such as from an Intravenous (IV) stand. In many embodiments, the interfaces 1171a, 1171b may be integrally formed with the container 1120 b. In the illustrated embodiment, the interfaces 1171a, 1171b are symmetrically disposed about a centerline of the container 1120 b.
Referring specifically to fig. 11C, the container 1120C may include one or more interfaces to couple with one or more of a stand, cradle, and rest. For example, the interface 1180 may include a ring or handle that may be used to hang the container 1120c, such as from an IV pole. In many embodiments, the interface 1180 may be integrally formed with the container 1120 c. In some embodiments, the fill port 1102 of the container 1120c may be on the face. In some such embodiments, positioning the fill port 1102 on the front face may reduce the height required to refill the container 1120c and/or promote the collapsibility of the container 1120c, such as by making it fold more flat. In many embodiments, the container 1120c is made of a flexible material. For example, the container 1120c may be similar to an IV bag.
FIG. 12 depicts a container 1220 in a first state 1250-1 and a second state 1250-2 according to one embodiment of the present invention. The container 1220 may be collapsible. Thus, state 1250-1 may represent an expanded state and state 1250-2 may represent a collapsed state. As mentioned previously, the collapsibility may reduce the need for storage space. Further, the collapsibility may reduce the need for storage space without sacrificing fluid retention capacity. More generally, the containers described herein may include a capacity in excess of 1 liter. For example, the container may have a capacity of between 3 and 5 liters. In another example, the container may have a capacity of up to 8 liters. As mentioned previously, one or more of the containers described herein may be flexible and/or collapsible. In some embodiments, the curved design of the neck may reduce or prevent the flow of liquid from the container into a gas supply tube connected to the container.
Fig. 13 depicts a container 1320 having a neck according to one embodiment of the invention. In various embodiments, the staged design of the neck may reduce or prevent flow of liquid into a gas supply tube connectable thereto. For example, the neck in the upper half of the container 1320 gradually or stepwise decreases in diameter. In some embodiments, the interface may be integrated into the neck. In one embodiment, the interface may include threads in the neck. For example, threads may be used to couple with an interface of an endoscope system.
Referring to fig. 14A and 14B, embodiments of an integrated vessel and tube set 1400A, 1400B are disclosed. According to one or more aspects of the present invention, the integrated vessel and tube set 1400A, 1400B may be substantially similar to the integrated vessel and tube set 500, 600, 700, 1100A, 1100B, 1100C disclosed above in connection with fig. 4-11C, except as outlined herein. Similarly, according to one or more aspects of the present invention, one or more components or features of the integrated vessel and tube sets 1400A, 1400B may be substantially similar to each other, except as outlined herein. Accordingly, a detailed description of similar elements may be omitted herein for brevity.
In general, fig. 14A and 14B show an integrated container and tube set (i.e., 1400A or 1400B) that includes a connector portion 1465, a coaxial tubing 1410 having a gas supply tubing 1440c and a lens wash tubing 1445c, a gas source supply tubing 1469, containers 1420A, 1420B having an upper half 1443 and a lower half 1447, an upstream lavage supply tubing 1419, a lavage pump 1415, and a downstream lavage supply tubing 1455c. Additionally, containers 1420a, 1420b may include fill port 1402 and interface 1490. In many embodiments, connector portion 1465 may be the same as or similar to connector portion 265, such as shown in fig. 2 and 4. The integrated container and tube set 1400A includes features for maintaining a gas pressure within at least a portion of the container 1420A. The integrated container and tube set 1400B includes features for facilitating rapid pressure build-up within at least a portion of the container 1420B. In many embodiments, these features may be used alone or in combination to reduce hysteresis in the lens cleaning function provided via the lens cleaning tubing 1445 c. For example, maintaining gas pressure within at least a portion of the vessel reduces the amount of gas that must be introduced into that portion of the vessel (e.g., into the top 1424) in order for liquid (e.g., in the bottom 1422) to flow up the lens cleaning tubing 1445c, out of the vessel, and out of the lens cleaning outlet (e.g., gas/lens cleaning outlet 220 of fig. 2). Thus, various embodiments may have a response time for the lens wash function of five seconds or less, such as one second. In various embodiments, the response time may refer to the amount of time from activating the lens wash function (e.g., by depressing the air/water valve 140 of fig. 2) until the liquid begins to flow out of the endoscope system (e.g., via the air/lens wash outlet 220 of fig. 2).
In fig. 14A, a check valve 1499a is included, wherein a gas supply pipe 1440c is coupled to the container 1420a. In various embodiments, the check valve 1499a may prevent gas from escaping from the top 1424 of the container 1420a. In other words, the check valve 1499a may only allow the flow of air from the gas supply pipe 1440c (e.g., air from the connector 1465 or CO from the gas source supply pipe 1469 2 ) Into the interior of container 1420a. In many embodiments, the pressure inside the top 1424 may remain closer to the pressure necessary to force the liquid in the bottom 1422 up the lens cleaning tubing 1445c and out of the container 1420a due to the check valve 1499 a. Thus, the lens purging function may be more responsive than the pressure in the container that must accumulate from a lower pressure (e.g., the pressure may be vented to atmosphere when the physician does not need air nor does it need to purge the lens with an air/water valve on the endoscope). For example, the check valve 1499a may maintain the pressure of the container 1420a between 1 and 8psi (above atmospheric pressure) rather than falling back to atmospheric pressure.
Additionally, in the integrated vessel and tube set 1400A, gas may be supplied via a gas source supply piping1469 are provided instead of via the connector portion 1465 or via alternative gas supply tubes as described above. In some such embodiments, the gas source supply tubing 1469 may actually be identical to the alternate gas supply tubing, the only difference being that gas may not be provided via a connector portion, such as from the booster pump 215 of the endoscope system 200. More generally, the various embodiments described herein may function in this manner without departing from the scope of the invention. In some such embodiments, a booster pump separate from the connector 1465 may be attached to the gas source supply piping 1469. In other such embodiments, a pressurized tank (e.g., air, oxygen, CO 2 Etc.) may be attached to the gas source supply piping. Similarly, the integrated vessel and tube sets 1400A, 1400B may utilize connector portions 1465 and/or alternative gas supply tubes without departing from the scope of the invention.
In some embodiments, a coaxial split connector may be used to couple coaxial tubing 1410 with container 1420a. The coaxial split connector may enable the use of standard check valves. Alternatively, an umbrella check valve may be used while the gas supply pipe 1440c and the lens cleaning pipe 1445c remain coaxial.
In FIG. 14B, container 1420B includes a first chamber 1437-1 and a second chamber 1437-2. The first chamber 1437-1 may be connected to the second chamber 1437-2 via a side channel 1433. The side passage 1433 may include a check valve that only allows flow from the second chamber 1437-2 to the first chamber 1437-1. Container 1420b may include a first chamber 1437-1 to provide a small volume in which pressure is established by introducing gas through gas supply tubing 1440c, but at the same time container 1420b facilitates achieving a larger total volume of available liquid in chamber 1437-2.
In many embodiments, with a much smaller first chamber 1437-1, the volume of air used to build up pressure to deliver lens wash is small, even if the water level has dropped to a low level, e.g., less than one quarter of the second chamber 1437-2. In this way, an undesirably long response time between requiring lens cleaning and delivery to the mirror is prevented.
In several embodiments, once the pressure in chamber 1437-1 drops sufficiently low, the head created by having a higher level of fluid in chamber 1437-2 may create a flow from second chamber 1437-2 into first chamber 1437-1 to refill first chamber 1437-1 back to a level equal to second chamber 1437-2. Additionally or alternatively, when the container is sufficiently flexible, the second chamber 1437-2 may be manually squeezed to force water from the second chamber 1437-2 into the first chamber 1437-1. Thus, container 1420b may be flexible and/or collapsible. In some embodiments, a second check valve may be included, such as described in relation to fig. 14A. In some such embodiments, umbrella check valves may be used in the coaxial tubing 1410. The fill port 1402 in the second chamber 1437-2 allows the chamber to be refilled. In many embodiments, fill port 1402 is the same as or similar to fill port 1102. If container 1420b is sufficiently flexible, the pressure in second chamber 1437-2 may be reduced by operating lavage pump 1415 to collapse second chamber 1437-2 without affecting the pressure in first chamber 1437-1. If the container 1420b is more rigid and no collapse of the container is required, a one-way vent (e.g., as part of the fill port 1402) may be included in the second chamber to allow atmospheric air to be drawn into the chamber when the lavage pump is operated, thereby maintaining the pressure at a level where the second chamber does not collapse. In either case, the pressure in the first chamber is not affected because the check valve 1199b prevents the drawing of liquid from the first chamber into the second chamber.
In the illustrated embodiment, the side channel 1433 includes a U-shaped connection between the first chamber 1437-1 and the second chamber 1437-2. However, the side channels 1433 may be configured in various ways without departing from the scope of the invention. For example, the side channel 1433 may be positioned against or within the bottom wall of the container 1420 b. In another example, the side channel 1433 may include an opening in a wall separating the first and second chambers 1437. In such an example, the check valve 1499b may be disposed in an opening in the wall. In many embodiments, the side channel 1433 may be integrally formed with the container 1420 b. In one embodiment, the side channels may not be included. For example, each chamber may have a separate fill port. In some embodiments, a side channel 1433 may be included along with separate fill ports for the two chambers to provide different ways for refilling the first chamber 1437-1. In one embodiment, the first chamber 1437-1 may have a capacity between 0.5 and 2 liters, such as 1 liter, and the second chamber 1437-2 may have a capacity between 1.5 and 8 liters, such as 4 liters.
