Abstract
An ultrasound probe is disclosed including a body (102), a lens included on head portion (44) of the body, a stabilizing portion (146) extending from the body and configured to stabilize the body on a skin surface of a patient without user assistance, and a finger-grip portion (110) configured to enable a user of the ultrasound probe to grasp and maneuver the ultrasound probe during use thereof with no more than two or three fingers on a single hand of the user. The ultrasound probe may further include a cable conduit (194) and a cable boot (195) configured to house a distal-end portion of a power-and-data cable and to keep the cable away from the head portion. The stabilizing portion may include a latitudinal channel (147) that reduces a surface area of the stabilizing portion intended to face the skin surface of the patient, in order to facilitate movement of the ultrasound probe across the skin surface and to reduce suction hen gel is present and the ultrasound probe is removed from the patient.

DESCRIPTION
[0098] Before some particular embodiments are disclosed in greater detail, it should be understood that the particular embodiments disclosed herein do not limit the scope of the concepts provided herein. It should also be understood that a particular embodiment disclosed herein can have features that can be readily separated from the particular embodiment and optionally combined with or substituted for features of any of a number of other embodiments disclosed herein.
[0099] Regarding terms used herein, it should also be understood the terms are for the purpose of describing some particular embodiments, and the terms do not limit the scope of the concepts provided herein. Ordinal numbers (e.g., first, second, third, etc.) are generally used to distinguish or identify different features or steps in a group of features or steps, and do not supply a serial or numerical limitation. For example, “first,” “second,” and “third” features or steps need not necessarily appear in that order, and the particular embodiments including such features or steps need not necessarily be limited to the three features or steps. Labels such as “left,” “right,” “top,” “bottom,” “front,” “back,” and the like are used for convenience and are not intended to imply, for example, any particular fixed location, orientation, or direction. Instead, such labels are used to reflect, for example, relative location, orientation, or directions. Singular forms of “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise.
[0100] With respect to “proximal,” a “proximal portion” or a “proximal-end portion” of, for example, a catheter disclosed herein includes a portion of the catheter intended to be near a clinician when the catheter is used on a patient. Likewise, a “proximal length” of, for example, the catheter includes a length of the catheter intended to be near the clinician when the catheter is used on the patient. A “proximal end” of, for example, the catheter includes an end of the catheter intended to be near the clinician when the catheter is used on the patient. The proximal portion, the proximal-end portion, or the proximal length of the catheter can include the proximal end of the catheter; however, the proximal portion, the proximal-end portion, or the proximal length of the catheter need not include the proximal end of the catheter. That is, unless context suggests otherwise, the proximal portion, the proximal-end portion, or the proximal length of the catheter is not a terminal portion or terminal length of the catheter.
[0101] With respect to “distal,” a “distal portion” or a “distal-end portion” of, for example, a catheter disclosed herein includes a portion of the catheter intended to be near or in a patient when the catheter is used on the patient. Likewise, a “distal length” of, for example, the catheter includes a length of the catheter intended to be near or in the patient when the catheter is used on the patient. A “distal end” of, for example, the catheter includes an end of the catheter intended to be near or in the patient when the catheter is used on the patient. The distal portion, the distal-end portion, or the distal length of the catheter can include the distal end of the catheter; however, the distal portion, the distal-end portion, or the distal length of the catheter need not include the distal end of the catheter. That is, unless context suggests otherwise, the distal portion, the distal-end portion, or the distal length of the catheter is not a terminal portion or terminal length of the catheter.
[0102] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art.
[0103] Embodiments disclosed herein are generally directed to an ultrasound probe for use with an ultrasound imaging system. In particular, the ultrasound probe is sized and configured so as to be supported and readily used with one or more fingers on a single hand of a user of the ultrasound imaging system, such as a clinician. This configuration enables remaining fingers on the hand of the user to be employed for other purposes, including applying traction to the skin surface of the patient proximate the imaging site, providing touch comfort to the patient, etc. With it supported by as little as a single finger, the ultrasound probe can easily be positioned by the user in a proper orientation against the skin surface during imaging procedures.
[0104] Further, the ultrasound probe is configured in one embodiment to enable the user's hand to be positioned substantially horizontally with respect to (i.e., parallel to) the skin surface of the patient, thus enabling relatively accurate ultrasound-probe positioning (e.g., lifting, placing, pressing, etc.) and scanning operations to be performed.
[0105] In one embodiment, the ultrasound probe also includes a stabilizing portion to assist in maintaining stability of the ultrasound probe while on the skin surface.
[0106] In one embodiment, the ultrasound probe is configured to be supported and manipulated by a single finger, with the finger positioned directly over a lens portion of the ultrasound probe. Such a position enables the user to easily and accurately move the ultrasound probe on the skin surface as to position the ultrasound probe with subtle movements as desired.
[0107]
[0108] In one embodiment, an optional cap including a hydrogel insert can be removably attached to the head 44 of the ultrasound probe 40 so as to cover a lens portion thereof. The hydrogel insert provides an ultrasonically transparent interface between the ultrasound-probe head 44 and the skin surface. A needle guide can also be included with the cap to assist with guiding needles through the patient's skin and into the vessel being imaged by the ultrasound imaging system 10. In another embodiment, the needle guide is included on the ultrasound probe itself. Further details regarding the ultrasound-probe cap, hydrogel insert, and needle guide can be found in U.S. Publication No. 2011/0313293 and U.S. Pat. No. 9,788,812, each of which is incorporated herein by reference in its entirety. In yet another embodiment, a sheath or cover can be removably placed over the ultrasound probe 40 to provide a sterile barrier. Note that other ultrasound imaging devices and ultrasound imaging systems that differ from that shown here can also benefit from the embodiments described herein.
[0109]
[0110] In operation of the ultrasound imaging system 10, a lens portion of the head 44 of the ultrasound probe 40 is placed against the skin of the patient so as to ultrasonically image a cross-sectional slice of a vessel, such as a vein, or other internal body tissue of the patient below the surface of the skin. Indeed, a target location of the vessel imaged by the ultrasound probe 40 is disposed a substantially vertical depth below the end of the ultrasound probe. The vessel is imaged by the ultrasound imaging system 10 in preparation for accessing the vessel with a needle in preparation for inserting a catheter into the vessel, in one embodiment. Though shown here as a vessel, the target location can be any one of various subcutaneous locations within the body.
[0111]
[0112] In the present embodiment, the ultrasound probe 40 includes a finger-grip portion 110 configured to enable the user of the ultrasound probe to grasp, support, and handle the ultrasound probe with one or more fingers of a single hand of the user while leaving one or more fingers of the user's hand free to be used in other ways. In the present embodiment, the finger-grip portion 110 includes two angled, protruding elements 114 extending from the opposing lateral surfaces 102A of the ultrasound-probe body 102. Each of the protruding elements 114 defines, together with a proximate portion of the lateral surface 102A of the ultrasound-probe body 102, a concavely shaped grip surface 118 into which a user's finger is received in order to support and move the ultrasound probe 40 during system operation.
[0113] In the present embodiment, the ultrasound probe 40 is placed between a forefinger (index finger) and a middle finger of a single hand of the user such that an inside portion of the forefinger engages one of the grip surfaces 118 and an inside portion of the middle finger engages the other grip surface on the opposing side of the ultrasound probe. In this way, the user is able to lift, maneuver, slide, and otherwise move the ultrasound probe 40 with only two fingers during operation of the ultrasound imaging system 10. Note that other fingers of the user's hand can alternatively be used to hold the ultrasound probe 40. This further enables the remaining three fingers of the user's hand to be employed in other ways during ultrasonic imaging by the ultrasound probe 40. These other ways include, for instance, applying traction to the skin surface, touching the patient in order to impart comfort, establishing or marking a physical reference point etc.
[0114] Note that the engagement of the ultrasound probe 40 by the hand of the user is such that the user's hand is positioned substantially parallel with respect to the skin surface of the patient, i.e., horizontally, in a typical imaging procedure. This in turn enables the user to move the ultrasound probe accurately and easily, with relatively small movements across the skin surface, which results in improved imaging results. Note also that the ultrasound-probe body 102 in this and other embodiments includes a suitable material, such as a thermoplastic. In one embodiment, the material includes R-5100 polyphenylsulfone.

[0116] In one embodiment, the size of the ring 124 can be configured such that the user's finger can be inserted varying distances through the ring in order to encounter a fit suitable for moving and handling the ultrasound probe 40. As such, the ring 124 can be sized in one or more of varying diameters. In another embodiment, an insert can be removably fitted in to the ring 124 to adjust the size of the ring opening to accommodate differently sized fingers. Note that in one embodiment, all or part of the finger-grip portion can be flexible/resilient so as to deform to a user's finger. Note also, that the ultrasound probe 40 in the embodiment illustrated in

[0119] In one embodiment, the size of the hook 134 can be configured such that different portions of the user's finger can be inserted into the hook in order to encounter a fit suitable for moving and handling the ultrasound probe 40. As such, the hook 134 can be sized in one or more of varying sizes. In another embodiment, an insert can be removably fitted in to the hook 134 to adjust the size thereof to accommodate differently sized fingers.

[0124] In one embodiment, the size of the cylindrical ring 154 can be configured such that the user's finger can be inserted varying distances through the ring in order to encounter a fit suitable for moving and handling the ultrasound probe 40. As such, the cylindrical ring 154 can be sized in one or more of varying diameters. In another embodiment, an insert can be removably fitted in to the cylindrical ring 154 to adjust the size of the ring opening to accommodate differently sized fingers. In yet another embodiment, the cylindrical ring 154 can have a varying diameter, such as being relatively wider at either end, so as to introduce freedom of movement for a finger inserted therein.
[0125] The ultrasound probe 40 of the embodiment of
[0126] Reference is now made to
[0127] As shown, the finger-grip portion 110 includes the cylindrical ring 124 extending from the body 102 of the ultrasound probe 40. The cylindrical ring 154 is sized in one embodiment to receive a finger of the user, such as the forefinger or middle finger. To that end, an inner cylindrical surface of the cylindrical ring 154 serves as the grip surface 118 against which the user's finger rests to enable the finger to handle and control movement of the ultrasound probe 40. It is thus noted that the finger-grip portion 110, i.e., the cylindrical ring 154 in the present embodiment, further serves as one example of a retention portion to retain engagement of the ultrasound probe 40 with the user's finger(s).
[0128] In one embodiment, the size of the cylindrical ring 154 can be configured such that the user's finger can be inserted varying distances through the ring in order to encounter a fit suitable for moving and handling the ultrasound probe 40. As such, the cylindrical ring 154 can be sized in one or more of varying diameters. In another embodiment, an insert can be removably fitted in to the cylindrical ring 154 to adjust the size of the ring opening to accommodate differently sized fingers.

As such, the cylindrical ring 154 can be sized in one or more of varying diameters. In another embodiment, an insert can be removably fitted in to the cylindrical ring 154 to adjust the size of the ring opening to accommodate differently sized fingers.
[0135] The ultrasound-probe body 102 further defines a protrusion 164 and a saddle 168 to provide a second grip surface 118 on which a second finger of the user's hand, such as the forefinger, can rest to further support and handle the ultrasound probe 40. Thus, two fingers of a user's single hand can be employed in the present embodiment to support and use the ultrasound probe 40. The saddle 168 enables the user's finger to be positioned substantially co-linearly above and in a spaced-apart relationship with respect to the lens 108 of the ultrasound-probe head 44. This enables the user to impart relatively fine amounts of pressure, or traction, to the skin surface via pressing down the ultrasound probe 40 thereon, and provides enhanced control over the ultrasound probe.

[0147]
[0148] The cable conduit 194 extends from the ultrasound-probe body 102 and two finger-grip portions 110 are included, namely, two channels 210 that are defined by the body and are disposed adjacent the cable conduit so as to provide two concavely shaped grip surfaces 118. Two fingers of a single hand of the user, such as the forefinger and middle finger, can be received into the channel 210 to support and handle the ultrasound probe 40, while enabling other fingers of the user's hand to be used for other purposes. These and other ultrasound probe body shapes and finger-grip portion configurations are therefore contemplated.
[0149] Note that the ultrasound probes discussed herein are further configured to enable a sterile cover to be thereover and for elastic bands to be used to secure the cover to the ultrasound probe. The ultrasound probes herein are also configured to be symmetrical along at least one midline axis so as to enable both left-handed and right-handed use.
[0150] In one embodiment, it is appreciated that icons/symbols may be placed on the ultrasound probe body 102 to assist a user in knowing where to place finger(s) for use of the ultrasound probe 40.
[0151]
[0152] As shown, the ultrasound probe 40 includes a body 102, a lens 108, a stabilizing portion 146 of the body 102, and a finger-grip portion 110 of the body 102. As best seen in
[0153] The body 102 of the ultrasound probe 40 can be formed of a molded thermoplastic such as polyphenylsulfone. Indeed, at least a top portion of the body 102 shown in
[0154] A head portion 44 of the ultrasound probe 40 is designated by at least the lens 108 disposed in the cutout or molded latitudinal hole of the body 102. The lens 108 is configured to pass ultrasound signals therethrough. The ultrasound signals include emitted ultrasound signals emitted by an array of piezoelectric transducers within the ultrasound probe 40 behind the lens 108. The ultrasound signals also include reflected ultrasound signals reflected into the ultrasound probe 40 such as from a tissue being imaged.
[0155] The stabilizing portion 146 of the ultrasound probe 40 is composed of a longitudinal extension of the body 102 extending away from the head portion 44 of the ultrasound probe 40. The stabilizing portion 146 is configured to stabilize the ultrasound probe 40 on a skin surface of a patient without assistance from a user of the ultrasound probe 40.
[0156] The stabilizing portion 146 of the ultrasound probe 40 includes a latitudinal channel 147 extending from side to side of two longitudinal sides of the ultrasound probe 40. The latitudinal channel 147 reduces a surface area of a generally flat surface of the stabilizing 146 portion intended to face the skin surface of the patient. The reduced surface area of the stabilizing portion 146 facilitates movement of the ultrasound probe 40 across the skin surface of the patient by reducing contact area between the surface of the stabilizing portion 146 and the skin surface of the patient. The reduced surface area of the stabilizing portion 146 also reduces suction between the surface of the stabilizing portion 146 and the skin surface of the patient when gel is therebetween and the ultrasound probe 40 is removed from the patient. In addition, the latitudinal channel 147 provides a space between the ultrasound probe 40 or the stabilizing portion 146 thereof and the skin surface of the patient into which a finger can be inserted for lifting the ultrasound probe 40 from the skin surface of the patient when removing the ultrasound probe 40 therefrom.
[0157] The finger-grip portion 110 of the ultrasound probe 40 is composed of a generally transverse extension of the body 102 extending away from the head portion 44 of the ultrasound probe 40. The finger-grip portion 110 is configured to enable the user to grasp and maneuver the ultrasound probe 40 during use thereof with no more than two or three fingers of a single hand. For example, the two fingers can be a thumb and an index finger. The finger-grip portion 110 of the ultrasound probe includes a concave grip surface 118 opposite a generally flat surface. The grip surface 118 is an extension of a concave surface of the stabilizing portion 146 of the ultrasound probe 40 intended to face away from the skin surface of the patient. In other words, the concave surface of the stabilizing portion 146 is opposite the generally flat surface of the stabilizing portion 146 intended to face the skin surface of the patient.
[0158] The ultrasound probe 40 includes a cable conduit 194 composed of a curved extension of the body 102 of the ultrasound probe 40 extending away from both the stabilizing and head portions of the ultrasound probe 40. The cable conduit 194 is configured to house a distal-end portion of a power-and-data cable such as the cable 104 for connecting the ultrasound probe 40 to the console 20. The cable conduit 194 is also configured to keep the power-and-data cable away from the head portion 44 of the ultrasound probe 40, thereby reducing interference by the power-and-data cable when using the ultrasound probe 40. As shown in
[0159] The ultrasound probe 40 includes a cable boot 195 having a distal-end portion disposed in an opening of the cable conduit 194. The cable boot 195 is configured to house the distal-end portion of the power-and-data cable proximal of the cable conduit 194. The cable boot 195 is also configured to keep the power-and-data cable farther away from the head portion 44 of the ultrasound probe 40. The cable boot 195 is also configured to attenuate a bending radius of the power-and-data cable about the opening of the cable conduit 194. Attenuating the bending radius of the power-and-data cable reduces a risk of damaging the power-and-data cable at the opening of the cable conduit 194 where the power-and-data cable is most likely to overbend from moving the ultrasound probe 40 when using the ultrasound probe 40.
[0160]
[0161] As shown, each ultrasound probe 40 includes a body 102, a head portion 44 of the body 102, and a finger-grip portion 110 of the body 102. Each ultrasound probe 40 is bilaterally symmetrical about a plane of symmetry of the ultrasound probe 40.
[0162] The body 102 of each ultrasound probe 40 can be formed of a molded thermoplastic such as polyphenylsulfone.
[0163] The head portion 44 of each ultrasound probe 40 is designated by at least a lens 108 disposed in a cutout or molded hole of the body 102. The lens 108 is configured to pass emitted and reflected ultrasound signals therethrough.
[0164] The finger-grip portion 110 of each ultrasound probe 40 is composed of a thimble-type structure of the body 102 of the ultrasound probe 40. The finger-grip portion 110 is configured to enable a user to insert, for example, an index or middle finger therein for maneuvering the ultrasound probe 40 during use thereof. The finger-grip portion 110 includes a grip surface 118 as set forth above.

Methods
[0166] A method of the ultrasound probe 40 includes an obtaining step of obtaining the ultrasound probe 40. For example, the obtaining step can include obtaining the ultrasound probe 40 of
[0167] The method also includes a connecting step of connecting the power-and-data cable of the ultrasound probe 40 to the console 20 of the ultrasound imaging system 10. The cable 104 extends from the cable conduit 194 and the cable boot 195 of the ultrasound probe 40. Again, the cable conduit 194 and the cable boot 195 is configured to keep the power-and-data cable away from the head portion 44 of the ultrasound probe 40 when using the ultrasound probe 40.
[0168] The method can include an applying step of applying an ultrasound gel to a skin surface of a patient before placing the ultrasound probe 40 on the skin surface of the patient.
[0169] The method also includes a grasping step of grasping the ultrasound probe 40. The grasping step includes placing at least one of an index finger or a middle finger on the concave grip surface 118 of the finger-grip portion 110 of the ultrasound probe 40, as well as a thumb on the opposing, generally flat surface of the finger-grip portion 110. The grasping step orients a palm of the single hand to which the foregoing fingers belong substantially parallel to the skin surface of the patient.
[0170] The method also includes a placing step of placing the head and stabilizing portions of the ultrasound probe 40 on the skin surface of the patient.
[0171] The method also includes an enabling step of enabling probing ultrasound signals to be emitted into the patient from the array of piezoelectric transducers within the ultrasound probe 40 for ultrasound imaging. The method also includes another enabling step of enabling reflected ultrasound signals to be reflected from the patient into the array of piezoelectric transducers within the ultrasound probe 40 for conversion into electrical signals for corresponding ultrasound images. The enabling of the foregoing enabling steps can include turning on the console 20, selecting one or more imaging modes of the ultrasound imaging system 10, or initiating ultrasound imaging with the ultrasound probe 40 by activating a start button or the like on the console 20.
[0172] The method also includes a moving step of moving the ultrasound probe 40 for the ultrasound imaging by the finger-grip portion 110 of the ultrasound probe 40 using no more than the foregoing two or three fingers of the single hand. The moving step does not overbend the power-and-data cable due to attenuation of the bending radius of the power-and-data cable by the cable boot 195.
[0173] The method also includes a removing step of removing the ultrasound probe 40 from the skin surface of the patient. Again, the stabilizing portion 146 of the ultrasound probe 40 includes the latitudinal channel 147 extending from side to side of the two longitudinal sides of the ultrasound probe 40. The latitudinal channel 147 reduces the surface area of the generally flat surface of the stabilizing portion 146, thereby reducing gel-induced suction between the surface of the stabilizing portion 146 and the skin surface of the patient during the removing step. In addition, the latitudinal channel 147 provides a space between the ultrasound probe 40 and the skin surface of the patient into which, for example, the index finger can be inserted for lifting the ultrasound probe 40 when removing the ultrasound probe 40 from the skin surface of the patient.
