The present invention relates, in general, to a suction adapter device. Specifically, to a surgical suction adapter device that enables a user to control the amount of suction within the device.
Human surgery entails incisions into human tissue or organs which lead to bleeding by the patient or release of bodily fluids into a surgical area. Such a release of blood or other bodily fluids hamper the surgery as they obscure the surgeon's view of the surgical site or area and thus lengthen the surgery while also placing the patient in danger. As such, surgeons have used suction devices to aspirate blood, bodily fluids and/or semi-solid biological material away from the surgical site or area. However, these suction devices tend to not have any way to effectively vary the amount of suction applied at the surgical site. In addition, some suction devices tend to clog up with tissue and other contaminants. Further still, these suction devices, by way of their many parts, enable further clogging because of the many parts of these devices and tend to be difficult to operate during surgery.
Accordingly, there is a need for a suction device adapter that would allow for a user to vary the amount of suction coming through the device. There is also a need for a device that, while enabling user variation of suction, prevents the device from being clogged with biological particles and/or other materials during the surgery. Further still, there is a need for a suction device adapter that is simple in its construction thereby reducing or eliminating the risk of it becoming clogged with tissue and other particles or materials.
Aspects of embodiments of the present invention contemplate a suction adapter which may include a nozzle configured to connect with suction tubing where the suction tubing may be connected with a suction source, a drain end, structurally configured to connect the adapter with a drain tube, where the drain tube may be used to aspirate a surgical site, a channel within the adapter, where the channel enables flow of fluid from the drain end through the nozzle of the adapter, and a fenestration extending from the channel to the adapter's external surface.
In an aspect of an embodiment of the present invention, the fenestration of the adapter may have multiple regions.
In an aspect of an embodiment of the present invention, the fenestration of the adapter may have first, second, third and fourth regions.
In an aspect of an embodiment of the present invention, the first region of the fenestration may be adjacent to the second region and where the second region may be adjacent to the third region and where the third region may be adjacent to the fourth region.
In an aspect of an embodiment of the present invention, the different regions may be contiguously adjacent to each other. For instance, the first region may be contiguously adjacent to the second region which may be contiguously adjacent to the third region and the third region may be contiguously adjacent to the fourth region.
In an aspect of an embodiment of the present invention, the first region of the fenestration the first region may be semi-circular in shape. In another aspect of an embodiment of the present invention, the second region may be rectangular in shape. In another aspect of an embodiment of the present invention, the fourth region may be circular in shape. In another aspect of an embodiment of the present invention, the third region may be of shape that enables it to provide a contiguous intermediate region between the second and fourth regions of the fenestration. In one aspect of an embodiment of the present invention, the third region may be any one of: trapezoidal, rectangular, or triangular in shape.
In another aspect of an embodiment of the present invention, the fenestration may enable user flow increase through the channel (or may be structurally configured to do so), enabling a user to progressively increase fluid flow through the channel where a user may do so by progressively closing the first through fourth regions of the fenestration. This may be done by having the user slide his or her finger first across the fenestration starting from the first region of the fenestration leading up to the fourth region while maintaining the closing of each region during the sliding process. It should be noted that this fluid flow increase control could also be implemented by having the user slide his or her finger the other way round—first from the fourth region and progressively to the first region.
In another aspect of an embodiment of the present invention, the fenestration may enable user flow reduction control (or may be structurally configured to do so), enabling a user to progressively decrease fluid flow through the channel where a user may do so by first closing the entire fenestration and progressively opening the fourth through first regions of the fenestration. This may be done by having the user first cover or close the entire fenestration and then slide his or her finger progressively from the fourth through the first regions of the fenestration. It should be noted that this fluid flow decrease control could also be implemented by having the user slide his or her finger the other way round—first from the first region and progressively to the fourth region.
In another aspect of an embodiment of the present invention, the walls of the fenestration may be angularly slanted in relation to the channel.
In another aspect of an embodiment of the present invention, the walls of the fenestration may be perpendicular in relation to the channel.
Additional aspects, objectives, features and advantages of the present invention will become apparent from the following description of the preferred embodiments with reference to the attached drawings.
