This application claims priority under US Patent Provisional Application No. 61 / 141,540 filed on December 30, 2008.
The present application relates to devices and methods for fluid application.
Patient preparation for various medical procedures, such as surgery, typically involves the application of a topical solution (or fluid), such as a disinfectant, to clean the area of interest for the medical procedure. The topical solution is applied to the area of interest by impregnating a material such as a sponge with the solution and using a handheld device, such as a pair of forceps or hemostats, to apply the soaked sponge to the area of interest. May be applied. The sponge or foam material is typically immersed in a fluid placed in an open dish or other container.
<p num="0004"> In some cases, existing devices used to apply solutions present various drawbacks. For example, a typical applicator uses a sponge that does not effectively retain the fluid, resulting in leakage. As a result, preparing the area to be disinfected and cleaned is a cumbersome procedure. In addition, leakage of various fluids onto areas outside the area of interest can lead to pools of various fluids that may cause irritation, discomfort, and / or other unwanted symptoms.</p><p num="0005"> Another example of the drawback is related to the difficulty of delivering the desired amount of fluid to the area of interest. During fluid application, in some cases it may be desirable to control the amount of fluid delivered by the applicator, eg disinfectant. However, because existing applicators distribute fluids inefficiently, it can be difficult to determine to deliver the correct amount of solution to the area of interest. This may result in more or less solution than desired being applied to the area of interest. In addition, typical applicators use foam and / or fluid delivery systems that are unable to deliver the correct amount of fluid in a timely manner. For example, some applicators with internal ampoules that store the fluid take time to soak the fluid into the sponge and thus become available for application to the patient. This can lead to unpredictable and inaccurate delivery of the desired solution.</p>

The term headings used herein are for the purpose of summarizing only and are not construed to limit the subject matter described. All documents cited in this application, including but not limited to patents, patent applications, literature, books, and treatises, are expressly incorporated by reference in their entirety for any purpose.
The disclosed applicator is configured to dispense / apply any liquid that passes through the disclosed device and has a suitable viscosity to allow it to be dispensed by the disclosed device. You may. In some embodiments, the disclosed applicator may be utilized to dispense / apply the disinfectant fluid. As used herein, the term "disinfecting fluid" refers to, in certain embodiments, a liquid that may be used to clean an area in preparation for various medical procedures.
Here, the reference to the drawing is made in detail. If possible, the same reference numbers will be used throughout the drawings to refer to the same or similar parts.
FIG. 1 illustrates an exploded view of the system 10 for applying fluid. As shown in FIG. 1, system 10 may include packets 12 configured to contain fluid. In addition, the system 10 may include an applicator device 14 configured to apply a fluid to the surface. The applicator device 14 may include a handle 16. The handle 16 may include a receptacle 18 at the proximal end 20 and a base 22 at the distal end 24. The applicator device 14 may also include an applicator pad 26 coupled to a base 22. The applicator device 14 may further include a lid 28 configured to enclose the packet 12 within the receptacle 18.
packet As shown in FIG. 1, the packet 12 may include a proximal end 30 and a distal end 32, with the distal end 32 of the packet 12 oriented towards the distal end 24 of the handle 16 and the receptacle. It may be configured to be inserted into 18. The fluid in packet 12 ruptures packet 12 (eg, in the destructible region), allowing (or forcing) the fluid to flow distally through the base 22 into the applicator pad 26. It may be discharged by applying an external force to the packet 12.
Packet 12 may be formed in any suitable shape. In some embodiments, packet 12 may have a substantially circular shape, as shown in the accompanying drawings. Packet 12 may be configured to fit within a receptacle 18, which may also be substantially circular as shown, and generally correspond to the shape of the receptacle 18. In some embodiments, the packet 12 may include an orientation mechanism to facilitate assembly of the components of the fluid coating system 10. For example, the packet 12 may have a shape corresponding to the fitting shape of the receptacle 18. In some embodiments, the mating shape may be asymmetric in order to orient the packet 12 with respect to the receptacle 18.
In certain embodiments, where the packet 12 and the receptacle 18 have a substantially circular mating shape (eg, as shown in FIG. 1), the orientation mechanism deviates from the substantially circular shape of the receptacle 18. It may include a structure on the receptacle 18 and a corresponding structure on the packet 12 that deviates from the substantially circular shape of the packet 12. For example, the orientation mechanism may include an asymmetric shape (forming a teardrop shape) such as the corresponding protrusions on the receptacle 18 and packet 12, as shown in FIG. That is, in some embodiments, the applicator device 14 may include a packet protrusion 36 on the packet 12 configured to be oriented with the corresponding receptacle mechanism 34 on the receptacle 18.
Asymmetric mating shapes, such as teardrops, may only facilitate assembly by making it easy to see how packet 12 and receptacle 18 are aligned with each other. It also guarantees that the destructible region of packet 12 is oriented towards the distal end of applicator device 14 so that the fluid released from packet 12 can easily flow to the applicator pad 26. May be done. For example, in certain embodiments, the receptacle 18 may be configured such that the packet 12 is oriented with the packet protrusion 36 located towards the base 22. In such an embodiment, the packet protrusion 36 may include a destructible region of the packet 12. The positioning of this destructible region (ie, towards the base 22) is to crush packet 12 when the destructible region is breached, for example by gravity and / or to eject fluid from packet 12 and receptacle 18. May allow fluid to easily flow from packet 12 towards base 22 (through base 22) into the applicator pad 26.
As shown in FIG. 2A, packet 12 may include opposing side portions 38 that define a sealed space 40 between which fluid may be filled. Either or both of the opposing side portions 38 may be deformable. The fluid in packet 12 opposes packet 12 with an external force that ruptures packet 12 and allows (or forces) the fluid to flow distally into the applicator pad 26 through base 22. It may be discharged by applying it to the side portion 38.
The destructible region of packet 12 may be configured to break and open when a reasonable activation force is applied (eg, by crushing / compressing packet 12). The destructible area may be configured to break and open when a force is applied by the user, but packets 12 containing the destructible area should be handled to prevent leakage or accidental opening. , May be configured to maintain structural integrity during storage, etc.
The packet 12 may be made of any type of material suitable for forming a fluid retention packet with a destructible region. For the purposes of the present disclosure, the term "destructible" is configured to be destructible, rupturable (as in the case of flexible packets), or otherwise destroyed. It means that it will be done. In some embodiments, the destructible region may be part of a packet prepared to have lower strength than the rest of the packet. For example, in certain embodiments, the destructible seal may be created by sealing the area where it is desired to be destructible at a temperature lower than the temperature required for maximum sealing strength. In other embodiments, the destructible seal may be provided by forming a destructible region with a specially formulated "peelable" film that has essentially lower adhesion.
The packet 12 may be self-excreting with a two-sided configuration that allows one side to smoothly flip into the other when the packet 12 is compressed. For example, as shown in FIGS. 2A and 2B, packet 12 may include a first packet side 42 and a second packet side 44. The first packet side portion 42 and the second packet side portion 44 may be sealed to each other by a sealing portion 46 near the peripheral portion of the packet 12. As shown in FIGS. 2C and 2D, packet 12 is configured so that when compressed, the first packet side 42 flips into the second packet side 44, thus crushing the sealed space 40. You may. Packet 12 may be configured to be completely crushed (and, in some embodiments, remain crushed) so as to exclude substantially all fluid from packet 12.
Packet 12 is such that the first packet side 42 of packet 12 is shown in FIGS. 2A and 2B so that when packet 12 is compressed, the previously sealed space 40 is substantially completely crushed.
