The present invention relates to medical devices and, in particular, to medical devices providing irrigation and suction.
Living beings such as humans and animals produce fluids as part of normal bodily functions. In some cases, the fluids are secretions from the nose or the mouth. In other cases, the fluids are accumulations of secretions that may change form over time, such as ear wax. Oftentimes, removal of the fluids is medically necessary or preferred. For example, fluids may be removed from the upper airway (i.e., the nose and/or mouth) of a baby, child or adult to aid in respiratory functionality. In another example, fluid such as blood may be removed from a body cavity prior to a medical procedure. In another example, ear wax or other fluid may be removed to aid in auditory functionality.
Manual or automated suction devices are conventionally used to remove fluids. Because the suction device must be placed in close proximity to or inside of the body cavity during suction, injury and trauma to the body and/or body cavity often results due to the design of the nozzle 40 portion of the suction device. Accordingly, there is a need for a suction device designed such that the likelihood of injury to the body and/or body cavity during use is relatively low.
Further, the fluid to be removed from the body cavity may be of a consistency making suction uncomfortable for the patient on which suction is performed. To make the fluid thinner and suction more comfortable, conventional approaches include irrigating the body cavity by depositing solution in the body cavity and then suctioning the fluid and the solution from the body cavity. This process, however, is quite cumbersome as the primary caregiver, whom may be holding or restraining a baby or other patient with one arm and hand, must with the other hand, retrieve an irrigation source, irrigate the body cavity, replace the irrigation source to its original position, retrieve the suction device, suction the body cavity and replace the suction device to its original position. The process may alternately disadvantageously require the assistance of a secondary caregiver to provide the irrigation to and suction of the body cavity while the primary caregiver holds or restrains the patient. The process is, in either case, unnecessarily time-consuming, which may be detrimental to the patient, especially in life-threatening medical emergencies. Accordingly, there is a need for a combination irrigation and suction device that may be operated by a single hand of a primary caregiver such that the primary caregiver may operate the device to perform irrigation and suction with one hand and may perform other medical duties such as holding or restraining a patient with another hand.
One or more embodiments of the present invention include a finger-controlled handpiece for combined irrigation and suction. The handpiece includes: a shaft having a first end and a second end distal from the first end. The shaft also has a channel disposed from the first end of the shaft to the second end of the shaft for allowing suction through the shaft. The handpiece also includes a nozzle coupled to the first end of the shaft; and an inlet disposed through an exterior surface of the shaft and in operable communication with the channel, the inlet being disposed to be manually covered and uncovered by one or more fingers of a single hand of a primary caregiver for control of suction through the shaft. The handpiece also includes a conduit having a first end disposed to receive a volume of irrigation solution after one or more fingers of the single hand of the primary caregiver act upon an irrigation source proximate to the conduit.
In some embodiments, the conduit is coupled to the exterior surface of the nozzle. In some embodiments, the first end of the conduit is coupled to the exterior surface of the shaft in communication with the channel. In some embodiments, the nozzle includes pliable material. In some embodiments, the shaft includes a rigid material.

In some embodiments, the system also includes a receptacle coupled to the second end of the shaft and being disposed to receive and retain fluid suctioned through the shaft. In some embodiments, the system also includes a suction mechanism coupled to the second end of the shaft and being disposed to provide suction force through the shaft.
One or more embodiments of the present invention is a finger-controlled handpiece for suctioning a body cavity. The handpiece includes: a shaft having a first end and a second end distal from the first end, the shaft also having a channel disposed from the first end of the shaft to the second end of the shaft for allowing suction through the shaft. The handpiece also includes a nozzle coupled to the first end of the shaft, the nozzle being pliable; and an inlet disposed through an exterior surface of the shaft and in operable communication with the channel, the inlet being disposed to be manually covered and uncovered by one or more fingers of a single hand of a primary caregiver for control of suction through the shaft.
In some embodiments, the nozzle is comprised of rubber. In some embodiments, the nozzle includes an end portion having a substantially flat configuration.
The handpiece 10 includes a shaft 15, a nozzle 40, an inlet 50 and a conduit 70. The shaft 15 includes a first end 20 and a second end 30 distal from the first end 20. The shaft 15 also includes a channel 35 disposed from the first end 20 of the shaft 15 to the second end 30 of the shaft 15 for allowing suction force through the shaft 15 between the first end 20 of the shaft 15 and the second end 30 of the shaft 15. In various embodiments, the first end 20 and/or the second end 30 may have a smooth or ribbed exterior surface facilitating attachment of one or more other components or devices to the shaft 15.
The shaft 15 may be composed of a rigid material, including but not limited to, hardened plastic or glass. Although the embodiment of the handpiece 10 shown illustrates the shaft 15 as elongated and tubular, other designs are possible and are envisaged within the scope of this patent application. In one or more embodiments, the shaft 15 may be any number of shapes that may be held in a single hand of a single caregiver and finger-controlled, including, but not limited to, cube- or dome-shaped.
The handpiece 10 also includes a nozzle 40 coupled to the first end 20 of the shaft 15. The nozzle 40 may be permanently or temporarily coupled to the first end 20 of the shaft 15 through any number of suitable methods. In various embodiments, the nozzle 40 may be welded, joined with adhesive or telescopically coupled to the shaft 15. Additionally, the nozzle 40 may include ridges on the interior of its surface for coupling to ridges of shaft 15.
The nozzle 40 is pliable. In various embodiments, the nozzle 40 is composed substantially of rubber, soft plastic or other pliable material. The nozzle 40 is generally conical-shaped. In various embodiments, the conical-shape may be more slender or less slender. The nozzles may be any of a number of sizes, including those suitable for premature or very low birth-weight babies (e.g., less than 3 pounds), normal birth weight and age or for normal sized babies (e.g., greater than 6-7 pounds). Accordingly, an angle from an end portion 60 of the nozzle 40 to a point on the exterior surface of the nozzle 40 may vary depending on the design of the nozzle 40 and all such variations are envisaged. The nozzle 40 may be coupled to the shaft by any suitable methods, including, but not limited to, welding, screw-on attachment or telescopic attachment.
A channel 42 of the nozzle 40 is located through the nozzle 40 wherein the first end 44 of the channel 42 of the nozzle 40 is in communication with the channel 35 of the shaft 15 and the second end 46 of the channel of the nozzle 40 is positioned near the end portion 60 of the nozzle 40 thereby creating a path for flow of suction force from the second end of the shaft 15 to the end portion of the nozzle 40.
The end portion 60 includes an end portion inlet (not shown) through the end portion 60 from the channel 42 to the outside environment. The end portion inlet in the end portion 60 of the nozzle 40 may be any number of diameters that can provide adequate suction and allow fluids of thick consistency, such as meconium secretions, to travel through the nozzle 40 and into the channel 35 of the shaft 15. Accordingly, when the end portion of the nozzle 40 is provided in close proximity to a body cavity, suction force may be provided to the body cavity through the end portion 60 of the nozzle 40.
The diameter of the end portion 60 and/or the exterior of the nozzle 40 generally may be any number of diameters. Accordingly, a nozzle 40 may be selected according to its design wherein the caregiver may take into account the age and/or medical condition of the patient.
In various embodiments, the end portion 60 may be of any design such that the end portion may meet with a body or body cavity and the likelihood of injury is relatively low. In various embodiments, the end portion 60 is substantially round or substantially flat in configuration. The substantially round and substantially flat configurations may be designed with curvature of various degrees such that one end portion 60 may be designed to be more circular or more angular than other configurations. Similarly, the flat configuration may be somewhat convex, concave or otherwise.
The handpiece 10 also includes an inlet 50 in the exterior surface of the shaft 15. The inlet 50 is in operable communication with the channel 35 of the shaft 15. The inlet 50 is shown located approximately midway between the first end 20 and the second end 30 of the shaft 15 but may be located at any position along the shaft 15 allowing a primary caregiver to cover the inlet 50 with one or more fingers of the single hand of the primary caregiver. The inlet 50 is disposed to be manually covered and uncovered by one or more fingers of a single hand of a primary caregiver for control of suction through the shaft 15. When the inlet 50 is substantially covered, suction commences through the end portion 60 of the nozzle 40 and into the body cavity. When the inlet 50 is substantially uncovered, suction through the end portion 60 of the nozzle 40 is removed or reduced.
While the inlet 50 is shown as a raised structure relative to the exterior surface of the shaft 15, in various embodiments of the present invention, the inlet 50 may be flush or depressed relative to the exterior surface of the shaft 15. Additionally, while the inlet 50 shown includes a flap 62 surrounding the inlet 50, the inlet 50 need only be an aperture in communication with the channel 35 of the shaft 15 and therefore need hot include the flap 62.
The handpiece 10 also includes a conduit 70. The conduit 70 includes a first end 80 and a second end 90 distal from the first end 80. The conduit 70 may be of any number of lengths or diameters. In one embodiment, the conduit 70 is of a diameter comparable to that of a 5 French feeding tube. In some embodiments, a connector 95 is coupled to the conduit 70. The connector 95 may provide a path from the conduit 70 to an irrigation source (not shown). The connector 95 may be any mechanism for coupling the conduit 70 to an irrigation source.
The conduit 70 is disposed to receive in a first end 80 of the conduit 70 an irrigation solution and to output a received irrigation solution from the second end 90 of the conduit 70. The conduit 70 has a first end 80 disposed to receive a volume of irrigation solution after one or more fingers of the single hand of the primary caregiver act upon an irrigation source proximate to the conduit 70.
The conduit 70 may be coupled to the exterior surface of the nozzle 40. The conduit 70 may be coupled to the nozzle 40 through any suitable method, including, but not limited to, a mechanical coupler (not shown), welding (not shown) or adhesive (not shown). Additionally, the conduit 70 may be connected in a temporary or permanent fashion to the nozzle 40.
Accordingly, when the conduit 70 is positioned near the body cavity of a patient, it may be used to irrigate the body cavity with an irrigation solution. The conduit 70 may be positioned in substantially the same direction as the nozzle 40 such that when the nozzle 40 is inserted into the body cavity of the patient, the conduit 70 provides a path for irrigation through the conduit 70 into the body cavity of the patient.
Although in the embodiment shown, the conduit 70 is coupled to the exterior of the nozzle 40, the conduit 70 may be coupled to the exterior of any portion of the handpiece 10 such that a body cavity is able to be irrigated using the conduit 70.
The nozzle 40 and conduit 70 are disposed to be inserted into one or more of a nose, a mouth, an ear or any other suitable body cavity. Accordingly, the primary caregiver may select and apply a nozzle 40 and/or conduit 70 having dimensions appropriate for the patient being treated. For example, the selected nozzle 40 may be a nozzle 40 appropriate for insertion into a body cavity of a baby (premature, neonate or otherwise), a child or an adult.
Accordingly, the device advantageously provides separate passageways for irrigation and suction such that the irrigation solution is not tainted by the fluid suctioned through the channel 35 of the shaft 15. Accordingly, the device reduces the likelihood of re-introduction of contaminated fluid into the body cavity of the patient.
The irrigation source 200 has a first end 210 and a second end 220 distal from the first end 210. The first end 210 of the irrigation source 200 is coupled to the first end of the conduit. In some embodiments, the irrigation source 200 is coupled to the first end of the conduit via connector 95. The connector 95 may be any mechanism for coupling the conduit to an irrigation source 200. The irrigation source 200 is disposed to contain irrigation solution used to irrigate the body cavity.
In some embodiments, the irrigation source 200 is formed of a material allowing the irrigation source 200 to be manipulated with one or more of other fingers on the single hand of the primary caregiver for controlling injection of irrigation solution with the handpiece 10. In one embodiment, the irrigation source 200 is composed of a material that is easily depressed with human fingers. In some embodiments, acting upon the irrigation source 200 includes depressing the irrigation source 200 with one or more fingers of the single hand of the primary caregiver. The irrigation source 200, upon being depressed, decreases in volume and causes irrigation solution to escape from the first end 210 of the irrigation source 200.
In some embodiments, the irrigation source 200 is an ampule disposed to contain a volume of irrigation solution. The ampule may be a 5 milliliter (ml) round or a 5 ml rectangle ampule. The ampule may be a 3-5 ml plastic container. In some embodiments, the irrigation solution is saline solution. The irrigation solution may be a solution of 0.9% saline, which is often referred to as a “normal saline” solution. The irrigation solution may be a solution that is approximately the same the human body's saline concentration. The ampule may be composed of a substantially transparent material allowing the primary caregiver to observe the amount of irrigation solution injected into the conduit, whether any irrigation solution is in the irrigation source 200 or if the irrigation source 200 is empty.
In some embodiments, the irrigation source 200 contains saline solution. In other embodiments, the irrigation source 200 may contain any fluid suitable for irrigating a body cavity, including, but not limited to, water, gases or aerosols.
In some embodiments, the irrigation source 200 may be integrally formed with the handpiece 10. In some embodiments, the irrigation source 200 may include a dispensing mechanism (not shown) disposed to be coupled to the first end 210 of the irrigation source 200 to provide one or more of a spray, droplet or stream of the irrigation solution. The dispensing mechanism may be coupled to the irrigation source 200. Accordingly, the dispending mechanism may provide a spray, droplet or a stream of fluid with the handpiece 10 as decided by the caregiver.
In some embodiments, the system includes a receptacle 230. In one embodiment, the receptacle 230 includes a first port 240 disposed to be coupled to the second end 30 of the shaft 15 and a second port 250 disposed to be coupled to a suction mechanism 260. The receptacle 230 is disposed to receive through its first port 240 fluid suctioned through the shaft 15 and to retain such suctioned fluid. In various embodiments, the receptacle 230 includes only a single port. In one embodiment, the receptacle 230 is coupled to the second end of the shaft 15 with one or more connectors (not shown). Accordingly, suction may be provided along a path from a suction mechanism 260 coupled to the second port 250 of the receptacle 230 through the receptacle 230 through the nozzle of the handpiece 10 and from the body cavity of the patient (not shown).
In embodiments of the receptacle 230 having a first port 240 and a second port 250, the first port 240 and the second port 250 may be positioned to be at different heights along the exterior surface of the receptacle 230 such that fluid may fall into the receptacle 230 and be maintained therein and not be suctioned into the suction mechanism 260. In one embodiment, the receptacle 230 includes a first port 240 that is lower in height than a second port 250 wherein the first port 240 is coupled to the handpiece 10 and the second port 250 is coupled to the suction mechanism 260. In various embodiments, the receptacle 230 may be a specimen cup, a sputum tap, a luki tube or any container for receiving and retaining fluid suctioned through the shaft 15.
Accordingly, the system may be used to retrieve and retain fluid for laboratory testing. For example, nasal secretions may be collected for identification of disease organisms. Generally, samples may be collected for culture and sensitivity tests.
In some embodiments, the system includes a suction mechanism 260. In one embodiment, the suction mechanism 260 is coupled to the second end 30 of the shaft 15. The suction mechanism 260 may be coupled to the shaft 15 with a tube. In some embodiments, the suction mechanism 260 is connected directly to the shaft 15. The suction mechanism 260 may be any machine disposed to provide suction force. The suction mechanism 260 may be electric or pneumatic powered. The suction mechanism 260 may provide 80-100 cm H2O suction pressure.
The handpiece 100 also includes a conduit 70′. The conduit 70′ includes a first end 80′ and a second end 90′ distal from the first end 80′. The second end 90′ of the conduit 70′ is coupled to a second inlet 75 in the shaft 115 of the handpiece 100 such that the channel of the shaft 115 is in communication with the conduit 70′.
With reference to
The conduit 70′ is disposed to receive in a first end 80′ of the conduit 70′ an irrigation solution and to output the received irrigation solution from a second end 90′ of the conduit 70′. The conduit 70′ has a first end 80′ disposed to receive a volume of irrigation solution after one or more fingers of the single hand of the primary caregiver act upon an irrigation source (not shown) proximate to the conduit 70′.
Accordingly, the conduit 70′ may deliver irrigation solution along a path from the second inlet 75 of the shaft 115 through the nozzle 140 and into the body cavity. Accordingly, a primary caregiver can provide irrigation and suction using the fingers of a single hand of the primary caregiver.
The nozzle 140 is disposed to be inserted into one or more of a nose, a mouth, an ear or any other suitable body cavity. Accordingly, the primary caregiver may select and apply a nozzle 140 having dimensions appropriate for the patient being treated. For example, the selected nozzle 140 may be a nozzle 140 appropriate for insertion into a body cavity of a baby (premature, neonate or otherwise), a child or an adult.
Accordingly, the device advantageously provides fast irrigation and suction of a body cavity using only the single hand of a primary caregiver.

The dispensing mechanism may be coupled to the irrigation source 400. Accordingly, the dispending mechanism may provide a spray, droplet or a stream of fluid with the handpiece 100 as decided by the caregiver.
In some embodiments, the system includes a receptacle 430. In one embodiment, the receptacle 430 includes a first port 440 disposed to be coupled to the second end 130 of the shaft 115 and a second port 450 disposed to be coupled to a suction mechanism 460. The receptacle 430 is disposed to receive through its first port 440 fluid suctioned through the shaft 115 and to retain such suctioned fluid. In various embodiments, the receptacle 430 includes only a single port. In one embodiment, the receptacle 430 is coupled to the second end 130 of the shaft 115 with one or more connectors (not shown). Accordingly, suction may be provided along a path from a suction mechanism 460 coupled to the second port 450 of the receptacle 430 through the receptacle 430 through the nozzle 140 of the handpiece 100 and from the body cavity of the patient (not shown).

The suction mechanism 460 may be electric or pneumatic powered.
A method of using the embodiments of the finger-controlled irrigation and suction systems and devices of
The suction mechanism is coupled to the second end of the handpiece and turned on to provide suction force in the handpiece. The first end of the conduit is coupled to the irrigation source such that the irrigation source is positioned to output a volume of irrigation solution with the handpiece after the irrigation source is depressed.
The nozzle of the handpiece is placed in close proximity to the body cavity at which irrigation and suction is desired. At the option of the primary caregiver, the nozzle may be placed inside the body cavity to a desired depth.
The primary caregiver uses a finger of the hand in which the handpiece is positioned to depress the irrigation source thereby injecting a volume of irrigation solution with the handpiece. The irrigation solution travels into the body cavity of the patient. Accordingly, the body cavity of the patient is irrigated. The consistency of the fluid may change in response to the type of the irrigation solution. For example, when the irrigation solution is a saline solution, the fluid may develop a consistency that is thinner than the consistency that the fluid prior to irrigation.
The primary caregiver uses a finger of the hand in which the handpiece is positioned to cover the inlet thereby causing suction to occur at the nozzle of the handpiece. Accordingly, fluid is suctioned from the body cavity that is in close proximity to the nozzle. The primary caregiver removes the finger of the hand in which the handpiece is positioned thereby uncovering the inlet to reduce or substantially remove suction at the nozzle. The primary caregiver may also partially cover or uncover the inlet to vary the amount of suction pressure at the nozzle.
Accordingly, the device allows a primary caregiver to perform irrigation and suction with a single hand and without the aid of a secondary caregiver. Therefore, a primary caregiver can hold a baby, infant or child with one arm and hand and provide both irrigation and suction with the other hand without the aid of a secondary caregiver. Further, simple finger control of the irrigation and suction device allows a primary caregiver to provide irrigation and suction in a short amount of time. Additionally, the primary caregiver can vary the amount of irrigation provided to the body cavity by taking into account one or more of the following factors: an appropriate amount of pressure depending on the volume of irrigation solution in the irrigation source or the length or diameter of the conduit.
The foregoing steps may be performed in any order at the discretion of the primary caregiver. For example, the primary caregiver may position the nozzle in close proximity to the body cavity with the inlet covered, uncovered or partially covered.
The handpiece 510 is a portable device disposed to provide suction of a body cavity. The handpiece 510 is disposed to be held and easily manipulated in the hand of a primary caregiver. The handpiece 510 may be held in a first hand of the primary caregiver while the primary caregiver holds or restrains a patient with a second hand of the primary caregiver.
The handpiece 510 includes a shaft 515, a nozzle 540 and an inlet 550. The shaft 515 includes a first end 520 and a second end 530 distal from the first end 520. The shaft 515 also includes a channel 535 disposed from the first end 520 of the shaft 515 to the second end 530 of the shaft 515 for allowing suction force through the shaft 515 between the first end 520 of the shaft 515 and the second end 530 of the shaft 515. In various embodiments, the first end 520 and/or the second end 530 may have a smooth or ribbed exterior surface facilitating attachment of one or more other components or devices to the shaft 515.
The shaft 515 may be composed of a rigid material, including but not limited to, hardened plastic or glass. Although the embodiment of the handpiece 510 shown illustrates the shaft 515 as elongated and tubular, other designs are possible and are envisaged within the scope of this patent application. In one or more embodiments, the shaft 15 may be any number of shapes that may be held in a single hand of a single caregiver and finger-controlled, including, but not limited to, cube- or dome-shaped.
The handpiece 510 also includes a nozzle 540 coupled to the first end 520 of the shaft 515. The nozzle 540 may be permanently or temporarily coupled to the first end 520 of the shaft 515 through any number of suitable methods. In various embodiments, the nozzle 540 may be welded, joined with adhesive or telescopically coupled to the shaft 515. Additionally, the nozzle 540 may include ridges on the interior of its surface for coupling to ridges of shaft 515.
The nozzle 540 is pliable. In various embodiments, the nozzle 540 is composed substantially of rubber, soft plastic or other pliable material. The nozzle 540 is generally conical-shaped. In various embodiments, the conical-shape may be more slender or less slender. Accordingly, an angle from an end portion 560 of the nozzle 540 to a point on the exterior surface of the nozzle 540 may vary depending on the design of the nozzle 40 and all such variations are envisaged. The nozzle 540 may be coupled to the shaft 515 by any suitable methods, including, but not limited to, welding, screw-on attachment or telescopic attachment.
A channel 542 of the nozzle 540 is located through the nozzle 540 wherein the first end 544 of the channel 542 of the nozzle 540 is in communication with the channel 535 of the shaft 515 and the second end 546 of the channel of the nozzle 540 is positioned near the end portion 560 of the nozzle 540 thereby creating a path for flow of suction force from the second end 30 of the shaft 515 to the end portion 560 of the nozzle 540.
The end portion 560 includes an end portion inlet (not shown) through the end portion 560 from the channel 542 to the outside environment. The end portion inlet in the end portion 560 of the nozzle 540 may be any number of diameters that can provide adequate suction and allow fluids of thick consistency, such as meconium secretions, to travel through the nozzle 540 and into the channel 535 of the shaft 515. Accordingly, when the end portion of the nozzle 540 is provided in close proximity to a body cavity, suction force may be provided to the body cavity through the end portion 560 of the nozzle 540.
The diameter of the end portion 560 and/or the exterior of the nozzle 540 generally may be any number of diameters. Accordingly, a nozzle 540 may be selected according to its design wherein the caregiver may take into account the age and/or medical condition of the patient.
In various embodiments, the end portion 560 may be of any design such that the end portion 560 may meet with a body or body cavity and the likelihood of injury is relatively low. In various embodiments, the end portion 560 is substantially round or substantially flat in configuration. The substantially round and substantially flat configurations may be designed with curvature of various degrees such that one end portion 560 may be designed to be more circular or more angular than other configurations. Similarly, the flat configuration may be somewhat convex, concave or otherwise.
The handpiece 510 also includes an inlet 550 in the exterior surface of the shaft 515. The inlet 550 is in operable communication with the channel 535 of the shaft 515. The inlet 550 is shown located approximately midway between the first end 520 and the second end 530 of the shaft 515 but may be located at any position along the shaft 515 allowing a primary caregiver to cover the inlet 550 with one or more fingers of the single hand of the primary caregiver. The inlet 550 is disposed to be manually covered and uncovered by one or more fingers of a single hand of a primary caregiver for control of suction through the shaft 515. When the inlet 550 is substantially covered, suction commences through the end portion 560 of the nozzle 540 and into the body cavity. When the inlet 550 is substantially uncovered, suction through the end portion 560 of the nozzle 540 is removed or reduced.
While the inlet 550 is shown as a raised structure relative to the exterior surface of the shaft 515, in various embodiments of the present invention, the inlet 550 may be flush or depressed relative to the exterior surface of the shaft 515. Additionally, while the inlet 550 may include a flap 562 surrounding the inlet 550, the inlet 550 need only be an aperture in communication with the channel 535 of the shaft 515 and therefore need not include the flap 562.
A method of using the finger-controlled suction device includes the following steps. The primary caregiver holds the handpiece in a first hand of the primary caregiver such that the primary caregiver has at least one finger that can be manipulated to cover the inlet in the exterior surface of the shaft. The suction mechanism is coupled to the second end of the handpiece and turned on to provide suction force in the handpiece. The nozzle of the handpiece is placed in close proximity to the body cavity from which suction is desired. At the option of the primary caregiver, the nozzle may be placed inside the body cavity to a desired depth. The primary caregiver uses a finger of the hand in which the handpiece is positioned to cover the inlet thereby causing suction to occur at the nozzle of the handpiece. Accordingly, fluid is suctioned from the body cavity that is in close proximity to the nozzle. The suctioned fluid may be received and retained by a receptacle in some embodiments. The primary caregiver removes the finger of the hand in which the handpiece is positioned thereby uncovering the inlet to reduce or substantially remove suction at the nozzle. The primary caregiver may also partially cover the inlet to vary the amount of suction pressure at the nozzle.
The foregoing steps may be performed in any order at the discretion of the primary caregiver. For example, the primary caregiver may position the nozzle in close proximity to the body cavity with the inlet covered, uncovered or partially covered.
Accordingly, the finger-controlled suction device allows a primary caregiver to perform suction with a single hand and without the aid of a secondary caregiver. Therefore, a primary caregiver can hold a baby, infant or child with one arm and hand and provide suction with the other hand without the aid of a secondary caregiver. Further, simple finger control of the finger-controlled suction device allows a primary caregiver to provide suction in a short amount of time. Additionally, the primary caregiver can vary the amount of suction pressure to an appropriate amount of pressure depending on the age or medical needs of the patient.
The height from the bottom of the channel of the shaft to the lower portion of the flap, B, is 16. The height from the bottom of the channel of the shaft to the higher portion of the flap, G, is 19. A finger rest 700 is provided for resting the hand of the primary caregiver in order to hold the handpiece in a stable position.
