HAND-OPERABLE VACUUM DEVICE
This patent relates to devices that can be manipulated by a user to expel or draw in a material. In one example, a hand-operable vacuum device can include an interface portion configured to contact a material. The hand-operable vacuum device can also include a deformable portion that extends along an axis that passes through the interface portion and wherein the deformable portion includes at least one longitudinally-oriented resilient structure that extends generally parallel to the axis.
The accompanying drawings illustrate implementations of the concepts conveyed in the present application. Features of the illustrated implementations can be more readily understood by reference to the following description taken in conjunction with the accompanying drawings. Like reference numbers in the various drawings are used wherever feasible to indicate like elements. Further, the left-most numeral of each reference number conveys the figure and associated discussion where the reference number is first introduced (where feasible).
The present description relates to hand-operable vacuum devices. In some cases, hand-operable vacuum devices can be manipulated by a user to draw material (e.g., solid, liquid, gas) into the device and/or expel material from the device. In some cases, hand-operable vacuum devices can be used to create a vacuum force or suction without necessarily drawing material into the device, and/or to pressurize gases or liquids within the device. The hand-operable vacuum device can be constructed such that a user can squeeze and deform the device and then the device is resiliently biased to return to an original configuration. The construction of the hand-operable vacuum device can include generally longitudinally arranged resilient outwardly-biasing structures that bias the device back to its original configuration more effectively than existing technologies. This effective bias can create relatively strong vacuum forces for drawing material into the hand-operable vacuum device.
ExamplesIn some cases, the hand-operable vacuum device 100 can be thought of as having a deformable portion 102 and an interface portion 104 that can include a nozzle 105. The deformable portion 102 can extend along a long axis that runs parallel to the x-reference axis. The deformable portion can be generally elongated, spherical, or other shape. The deformable portion can include one or more resilient outwardly-biasing structures 106. In some implementations the resilient outwardly-biasing structures can be longitudinally oriented (i.e., parallel to the long axis). In this case, the hand-operable vacuum device includes a pair of resilient outwardly-biasing structures 106(1) and 106(2).
The deformable portion 102 can be manipulated or squeezed by a user as indicated by arrows 402 and 404 to deform or squish the deformable portion. The squishing can bend the resilient outwardly-biasing structures as can be seen by comparing
The example implementations above include a pair of outwardly-biasing structures 106(1) and 106(2).
In other configurations, the hand-operated vacuum device 2000 can be manufactured and filled with a liquid, such as a wound cleansing antiseptic solution or a mouthwash. The removable cap can then be added to maintain the integrity of the liquid until use. A user can remove the removable cap and propel the liquid from the nozzle by squeezing the deformable portion 2002.
In some implementations, the vent 2212 can be an alternative opening to the nozzle 2210 for air to flow in and out of the hand-operated vacuum device 2200. The vent 2212 can be ergonomically positioned on the hand-operated vacuum device 2200 such that a user can place their thumb or finger over the vent 2212. The ridges 2214 can provide friction to make the hand-operated vacuum device 2200 easier to grasp by the user. The constriction ring 2216 can be a separate part. The constriction ring can be designed with a size and shape such that the constriction ring lies flush against an outer end of the nozzle while the hand-operated vacuum device 2200 is being used. Other shapes and/or configurations of vents, ridges, and/or constriction rings can alternatively or additionally be utilized.
The hand-operated vacuum device 2200 can be made in a variety of sizes. For example, the hand-operated vacuum device 2200 could be offered in relatively “small,” “medium,” and “large” sizes. The sizing of the hand-operated vacuum device 2200 can correspond to a diameter of the nozzle 2210 and/or the constriction ring 2216. For instance, an outer diameter of the constriction ring can range from approximately 1⅜ inches to 1⅝ inches for the various sizes, while an inner diameter of the constriction ring can range from 13/16 inches to 1⅛ inches. An overall length of the hand-operated vacuum device 2200 can also vary accordingly. Other dimensions and/or sizing options are contemplated for the various hand-operated vacuum devices.
In some implementations, when employed as a dental squirt pick intended for use by an adult, an overall length of hand-operated vacuum device 2600 can be approximately 6 inches from an end of the deformable portion 2602 to a far end of the nozzle 2610. Where the hand-operated vacuum device is intended for use a dental squirt pick by a child, the overall length could be less than that intended for use by the adult, such as eighty percent less, or approximately 5 inches. Other lengths and/or other dimensions are contemplated.
Hand-operated vacuum devices can be manufactured utilizing various techniques and/or materials. For instance, in some implementations the hand-operated vacuum devices can be formed via a molding process, such as injection molding or blow molding. Various materials can be utilized including but not limited to various polymers. In some cases, a portion of a hand-operated vacuum device can be made from a different material than another portion. For instance, the interface portion can be made from a hard plastic. In another instance, referring to hand-operated vacuum device 4500 shown in
In some cases the hand-operated vacuum devices can be manufactured as a single piece, yet the interface portion can be thicker than the deformable portion so that the interface portion is relatively rigid while the deformable portion is readily deformed by a user. For instance, such a configuration can be achieved by blow molding where the polymer is introduced at the interface end of the hand-operated vacuum device. In one such example, the deformable portion can have an average thickness of 0.1-0.3 millimeters while the interface portion has an average thickness of 0.3-0.6 millimeters. In other examples, the hand-operated vacuum devices can be manufactured as multiple pieces.
In summary, hand-operable vacuum devices are described that can allow great vacuum (and/or expulsion) forces to be created by a user. The hand-operable vacuum devices can be inexpensively manufactured and can be disposable and/or reusable. In some instances, the hand-operable vacuum devices can be manufactured and/or packaged so that the devices are sterile until the packaging is opened. Further, the hand-operable vacuum devices lend themselves to construction from materials that can be transparent so that the user can see the contents (if any).

Rather, the specific features are disclosed as exemplary forms of implementing the claimed statutory classes of subject matter.
