Abstract

Devices, systems, and methods for a fluid supply for an endoscope. An expandable gas chamber presses against a saline chamber, allowing for the supply of pressurized saline to both a lens wash line and an irrigation line. As the saline chamber is emptied and decreases in volume the gas chamber receives more gas and increases in volume to maintain the fluid pressure.

Claims (15)

  1. 1. A multi-chamber fluid container for a medical device, comprising: a fluid chamber in fluid communication with a first fluid outlet and a second fluid outlet; and a gas chamber in mechanical contact with the fluid chamber, the gas chamber receiving gas to apply pressure to the fluid chamber in order to maintain fluid pressure within the fluid chamber.
  2. 2. The fluid container of claim 1, wherein the fluid chamber is a bag comprising a flexible material such that the bag decreases in volume as fluid flows out of the first and second fluid outlets.
  3. 3. The fluid container of any of claims 1 to 2, wherein the gas chamber is a bag comprising a flexible material such that the bag increases in volume as the gas chamber receives gas to apply pressure to the fluid chamber.
  4. 4. The fluid container of any of claims 1 to 3, comprising a pole mount suitable for hanging the container on a conventional pole for an intravenous fluid supply bag.
  5. 5. The fluid container of any of claims 1 to 4, wherein the gas chamber is in fluid communication with a gas cartridge.
  6. 6. The fluid container of any of claims 1 to 5, further comprising a rigid body containing the fluid chamber and the gas chamber, the rigid body defining a volume that does not expand or contract in response to fluid flow into or from the chamber.
  7. 7. The fluid container of claim 6, wherein the rigid body includes an openable portion for replacement of the saline chamber.
  8. 8. The fluid container of any of claims 1 to 7, further comprising a saline source in fluid communication with the saline chamber.
  9. 9. The fluid container of claim 8, wherein the saline source is an intravenous saline supply bag configured to supply a saline drip to the saline chamber.
  10. 10. The fluid container of any of claims 1 to 9, further comprising an air pump in fluid communication with the gas chamber.
  11. 11. The fluid container of claim 10, wherein the air pump is a user-actuated bellows pump.
  12. 12. The fluid container of claim 11, wherein the user-actuated bellows pump has a greater air capacity than the gas chamber.
  13. 13. The fluid container of any of claims 1 to 12, wherein the fluid chamber contains saline.
  14. 14. An endoscopic surgical device, comprising: an endoscopic probe having a lens wash feed line and an irrigation feed line; and the fluid container of any one of claims 1 to 13, wherein the first fluid outlet supplies fluid to the lens wash feed line and the second fluid outlet supplies fluid to the irrigation feed line.
  15. 15. The device of claim 14, further comprising a first valve actuated by a user to open the lens wash feed line, and a second valve actuated by a user to open the irrigation feed line.

Description

LENS WASH AND IRRIGATION FOR ENDOSCOPY CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63/517,533 filed on August 3, 2023, the disclosure of which is incorporated herein by reference. TECHNICAL FIELD [0002] This disclosure relates generally to valve assemblies and methods, and particularly to liquid supply during endoscopy BACKGROUND [0003] A wide variety of intracorporeal medical devices and systems have been developed for medical use, for example, for endoscopic procedures. Some of these devices and systems include guidewires, catheters, catheter systems, endoscopic instruments, and the like. These devices and systems are manufactured by any one of a variety of different manufacturing methods and may be used according to any one of a variety of methods. Of the known medical devices, systems, and methods, each has certain advantages and disadvantages. There is an ongoing need to provide alternative medical devices and systems as well as alternative methods for manufacturing and using medical devices and systems. SUMMARY [0004] This disclosure provides design, material, manufacturing method, and use alternatives for medical devices and medical systems. In a first example, multichamber fluid container for a medical device, can include a fluid chamber in fluid communication with a first fluid outlet and a second fluid outlet and a gas chamber in mechanical contact with the fluid chamber, the gas chamber receiving gas to apply pressure to the fluid chamber in order to maintain fluid pressure within the fluid chamber. [0005] Alternatively or additionally to any of the examples above, the fluid chamber can be a bag comprising a flexible material such that the bag decreases in volume as fluid flows out of the first and second fluid outlets. [0006] Alternatively or additionally to any of the examples above, the gas chamber can be a bag comprising a flexible material such that the bag increases in volume as the gas chamber receives gas to apply pressure to the fluid chamber. [0007] Alternatively or additionally to any of the examples above, the gas chamber can further include a pole mount suitable for hanging the container on a conventional pole for an intravenous fluid supply bag. [0008] Alternatively or additionally to any of the examples above, the gas chamber can be in fluid communication with a gas cartridge. [0009] Alternatively or additionally to any of the examples above, the fluid container further includes a rigid body containing the fluid chamber and the gas chamber, the rigid body defining a volume that does not expand or contract in response to fluid flow into or from the chamber. [0010] Alternatively or additionally to any of the examples above, the rigid body can include an openable portion for replacement of the saline chamber. [0011] Alternatively or additionally to any of the examples above, the fluid container can further include a saline source in fluid communication with the saline chamber. [0012] Alternatively or additionally to any of the examples above, the saline source can be an intravenous saline supply bag configured to supply a saline drip to the saline chamber. [0013] Alternatively or additionally to any of the examples above, the fluid container can further include an air pump in fluid communication with the gas chamber. [0014] Alternatively or additionally to any of the examples above, the air pump can be a user-actuated bellows pump. [0015] Alternatively or additionally to any of the examples above, the user-actuated bellows pump can have a greater air capacity than the gas chamber. [0016] Alternatively or additionally to any of the examples above, the fluid chamber can contain saline. [0017] In another example, an endoscopic surgical device an endoscopic probe having a lens wash feed line and an irrigation feed line and a fluid container according to any of the examples above, wherein the first fluid outlet supplies fluid to the lens wash feed line and the second fluid outlet supplies fluid to the irrigation feed line. [0018] Alternatively or additionally to any of the examples above, the device can further comprise a first valve actuated by a user to open the lens wash feed line, and a second valve actuated by a user to open the irrigation feed line. [0019] These and other features and advantages of the present disclosure will be readily apparent from the following detailed description, the scope of the claimed invention being set out in the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS [0020] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate various embodiments and together with the description serve to explain the principles of the present disclosure.
