The present invention relates generally to the field of syringe injector devices. More specifically, the present invention relates to a device that utilizes a screw-like thread component to depress the plunger on a syringe to administer medication at a consistent rate. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices and methods of manufacture.
By way of background, this invention relates to improvements in syringe injector devices. Generally, medications containing hyaluronidase are administered as an injection into fatty tissue, typically in the abdomen, over five minutes. However, because of the viscosity of the medication and variations between nurses giving the medication, the rate of delivery over the five minutes varies. Further, self-administration may not be possible for patients, as they may not be receiving the benefits of the medication, if improperly administered.
Additionally, even nurses and other healthcare professionals can apply to much force to the injector of a syringe, causing the prescribed does to be exceeded or to be injected too fast. These problems can lead to medical accidents. In addition, when the conventional drug injector is pulled outward instead of pressurizing the pressurizer, the drug flows back into the case so that the drug is not quantitatively injected or the patient's blood flows back.
Accordingly, there is a demand for an improved syringe injector device that allows users to rotate a screw-like thread to depress a plunger and administer medication at a consistent rate. More particularly, there is a demand for a syringe injector device that includes different thread patterns to accommodate various application rates and medication volumes.
Therefore, there exists a long felt need in the art for a syringe injector device that allows users to rotate a screw-like thread to depress the plunger on the syringe and administer medication at a consistent rate. There is also a long felt need in the art for a syringe injector device that offers a better and more effective way for nurses and other healthcare professionals to accurately administer medication through subcutaneous injections. Further, there is a long felt need in the art for a syringe injector device that provides users with a syringe injector designed to make it much easier for administering medications containing hyaluronidase. Moreover, there is a long felt need in the art for a device that includes different thread patterns that can be altered to accommodate various application rates and medication volumes. Further, there is a long felt need in the art for a syringe injector device that prevents medical accidents of injecting too much medication or injecting the medication too fast. Finally, there is a long felt need in the art for a syringe injector device that allows for a consistent, measured rate of subcutaneous injections via the rotations of the screw.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a syringe injector device. The device is a syringe injector for administering more viscous medications such as those containing hyaluronidase. The syringe injector device comprises a body component that is configured to retain a standard syringe. The body component also comprises a screw-like thread component that can be rotated to depress a plunger of the standard syringe. Specifically, the body component resembles a caulking gun which retains a syringe. The screw-like thread component is rotated during use. As the screw-like thread component is rotated, it depresses the plunger on the syringe, thus injecting the medication into the subcutaneous space. Further, by calculating the rotational distance and volume, a consistent administration rate can be achieved. For example, one rotation every 20 seconds would result in 15 ml over 5 minutes. Further, the thread pattern can be altered to accommodate various rates/volumes. Accordingly, the syringe injector device allows for a consistent, measured rate of subcutaneous injections via the rotations of the screw-like thread component.
In this manner, the syringe injector device of the present invention accomplishes all of the forgoing objectives and provides users with a device that administers medication at a consistent rate. The device provides a syringe injector to administer medication through subcutaneous injections. The device includes different thread patterns.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some general concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a syringe injector device. The device is a syringe injector for administering more viscous medications such as those containing hyaluronidase. The syringe injector device comprises a body component that is configured to retain a standard syringe. The body component also comprises a screw-like thread component that can be rotated to depress a plunger of the standard syringe. As the screw-like thread component is rotated, it depresses the plunger on the syringe, thus injecting the medication into the subcutaneous space. Accordingly, the syringe injector device allows for a consistent, measured rate of subcutaneous injections via the rotations of the screw-like thread component.
In one embodiment, the syringe injector device is a screw-type injector which may be used for pumping or injecting a liquid, and is particularly suitable for pumping a thick, viscous liquid medication, such as but not limited to, hyaluronidase and medications containing hyaluronidase. The syringe injector device comprises a body component and a screw-like thread component which retain a standard syringe.
In one embodiment, the syringe used with the syringe injector device is a standard syringe as is known in the art and comprises a barrel with a plunger. Specifically, the barrel of the syringe has a distal end and a proximal end, wherein the distal end refers to the end that is distal to the patient in use and the proximal end refers to the end that is proximal to the patient in use, wherein the proximal end may be connected to a needle and the distal end comprises a handle component that a user can grip to depress the plunger. In this embodiment, a needle is detachably connected to the proximal end of the barrel, for injecting medication from the syringe.
Further, the plunger has an external radial seal which forms a seal with the inner wall of the syringe barrel during use. Additionally, the plunger has a connecting end and an operating end, the connecting end penetrates into the syringe barrel through the distal end and is adjacent to the proximal end, the operating end is kept outside the syringe barrel and includes a push component suitable for a user to operate and push the plunger to slide into the barrel of the syringe. Further, the radial seal is located at the connecting end and creates a piston assembly that is disposed at the connecting end and which acts to slide with the plunger in the barrel. Thus, the piston assembly slides in the barrel when the plunger moves axially, and suction can be performed when the plunger moves towards the distal end.
In one embodiment, the syringe injector device comprises a body component and a screw-like thread component. The screw-like thread component is detachably connected to the body component and once threaded in position, contacts the push component of the plunger. As the screw-like thread component is rotated, it depresses the plunger on the syringe and injects the medication within the syringe into the subcutaneous space.
In one embodiment, the body component of the syringe injector device is configured in a half-pipe design with an open cavity for retaining the syringe. Thus, the body component is formed in a cylindrical shape, with a receiving space formed therein for receiving a conventional syringe. Specifically, the body component resembles a caulking gun, as is known in the art. The body component can be any suitable shape and size as is known in the art, as long as it acts to retain a syringe. The body component can also be available in different sizes to accommodate different sizes of syringes.
In one embodiment, the body component comprises a distal end and a proximal end. The proximal end comprises a threaded sleeve fitting for accepting the screw-like thread component. The distal end comprises a semi-circular retaining component that releasably secures the syringe via contact with the handle component of the barrel. Thus, the handle component of the barrel is slid between the semi-circular retaining components, to retain the syringe within the body component. Further, the threaded sleeve fitting is threadedly engaged with the screw-like thread component and allows the screw-like thread component to be detachably connected to the proximal end of the body component. Rotating the screw-like thread component within the body component, contacts the push component of the plunger and drives the plunger to slide in an axial direction of the barrel.
In one embodiment, the screw-like thread component is configured in a screw-like design with a gripping head and a threaded shank that threads into the threaded sleeve fitting. The screw-like thread component can be any suitable shape and size as is known in art, as long as the thread component allows a user to comfortably grip and turn the thread component during use. Further, the thread pattern can be altered to accommodate various rates/volumes, depending on the wants and/or needs of a user. For example, one rotation every 20 sections would result in 15 ml of medication dispensed over 5 minutes. In one embodiment, different screw-like thread components with differing thread patterns can be included with the body component for use. Thus, the different thread patterns can be altered to accommodate various application rates and medication volumes.
In use, a syringe is filled with medication and the plunger pulled out, creating negative pressure in the barrel of the syringe. It should be noted that, if the liquid is thick, a large negative pressure is formed in the syringe. The filled syringe is then positioned in the body component and secured via the handle component of the barrel secured within the semi-circular retaining component. The screw-like thread component is then screwed into the threaded sleeve fitting, such that the threaded shank contacts the push component of the plunger. Rotation of the screw-like thread component depresses the plunger on the syringe, injecting the medication into the subcutaneous space. Thus, the device allows for a consistent, measured rate of subcutaneous injections via the rotations of the screw-like thread component. Further, the thread pattern of the thread component can be altered to accommodate various application rates and medication volumes. By calculating the rotational distance and volume, a consistent administration rate can be achieved, even if the injection is performed at home and/or by a user who is not a trained medical professional.
In one embodiment, the syringe injector device is a reusable component that can be utilized over and over with different syringes, as needed. In another embodiment, the syringe injector device is disposable after use. Further, the device can be manufactured from common molding processes and made of heat-sealable plastic or polymers, such as polypropylene or acrylonitrile-butadiene-styrene (ABS), or any other suitable material as is known in the art, such as but not limited to, acrylic, polycarbonate, polyethylene, polyethylene terephthalate, polyvinyl chloride, polystyrene, etc. Generally, the syringe injector device is also manufactured from a material that is water resistant or waterproof, or the body component comprises a coating that is water resistant or waterproof. Furthermore, the device can be made of antibacterial or antimicrobial material or the body component comprises a coating that is antibacterial or antimicrobial.
In one embodiment, a locking member is positioned on the threaded shank of the screw-like thread component. The locking member serves to prevent reverse rotation of the screw-like thread component. Thus, the locking member prevents the thread component from being reversely rotated, during use. In one embodiment, the screw-like thread component is rotated in one direction to advance the plunger of the syringe. By employing the locking member, reverse rotation is prevented and the plunger is not drawn up the syringe barrel and medication is prevented from flowing back up in the syringe.
In yet another embodiment, the syringe injector device comprises a plurality of indicia.
In yet another embodiment, a method of administering medication at a consistent rate via a syringe is disclosed. The method includes the steps of providing a syringe injector device comprising a body component and a screw-like thread component that retain a syringe and plunger. The method also comprises filling a syringe with medication. Further, the method comprises inserting the filled syringe into the body component. The method also comprises rotating the screw-like thread component which contacts the plunger and depresses it. Finally, the method comprises injecting the medication at a consistent, measured rate via the rotation of the screw-like thread component.

The syringe injector device 100 comprises a body component 102 and a screw-like thread component 104 which retain a standard syringe 106.
As shown in
Furthermore, the plunger 108 has an external radial seal 122 which forms a seal with the inner wall 124 of the syringe barrel 112 during use. Additionally, the plunger 108 has a connecting end 126 and an operating end 128, the connecting end 126 penetrates into the syringe barrel 112 through the distal end 114 and is adjacent to the proximal end 116, the operating end 128 is kept outside the syringe barrel 112 and includes a push component 130 suitable for a user to operate and push the plunger 108 to slide into the barrel 112 of the syringe 106. Further, the radial seal 122 is located at the connecting end 126 and creates a piston assembly 132 that is disposed at the connecting end 126 and which acts to slide with the plunger 108 in the barrel 112. Thus, the piston assembly 132 slides in the barrel 112 when the plunger 108 moves axially, and suction can be performed when the plunger 108 moves towards the distal end 114.
Additionally, the syringe injector device 100 comprises a body component 102 and a screw-like thread component 104. The screw-like thread component 104 is detachably connected to the body component 102 and once threaded in position, contacts the push component 130 of the plunger 108. As the screw-like thread component 104 is rotated, it depresses the plunger 108 on the syringe 106 and injects the medication 110 within the syringe 106 into the subcutaneous space.
Generally, the body component 102 of the syringe injector device 100 is configured in a half-pipe design with an open cavity 200 for retaining the syringe 106. Thus, the body component 102 is formed in a cylindrical shape, with a receiving space 200 formed therein for receiving a conventional syringe 106. Specifically, the body component 102 resembles a caulking gun, as is known in the art. The body component 102 can be any suitable shape and size as is known in the art, as long as it acts to retain a syringe 106. The body component 102 can also be available in different sizes to accommodate different sizes of syringes 106, depending on the needs and/or wants of a user.
Furthermore, the body component 102 comprises a distal end 202 and a proximal end 204. The proximal end 204 comprises a threaded sleeve fitting 206 for accepting the screw-like thread component 104. The distal end 202 comprises a semi-circular retaining component 208 that releasably secures the syringe 106 via contact with the handle component 120 of the barrel 112. Thus, the handle component 120 of the barrel 112 is slid between the semi-circular retaining components 208, to retain the syringe 106 within the body component 102. Further, the threaded sleeve fitting 206 is threadedly engaged with the screw-like thread component 104 and allows the screw-like thread component 104 to be detachably connected to the proximal end 204 of the body component 102. Rotating the screw-like thread component 104 within the body component 102, contacts the push component 130 of the plunger 108 and drives the plunger 108 to slide in an axial direction of the barrel 112.
Additionally, the screw-like thread component 104 is configured in a screw-like design with a gripping head 210 and a threaded shank 212 that threads into the threaded sleeve fitting 206. The screw-like thread component 104 can be any suitable shape and size as is known in art, as long as the thread component 104 allows a user to comfortably grip and turn the thread component 104 during use. Further, the thread pattern 214 can be altered to accommodate various rates/volumes, depending on the wants and/or needs of a user. For example, one rotation every 20 sections would result in 15 ml of medication dispensed over 5 minutes. In one embodiment, different screw-like thread components 104 with differing thread patterns 214 can be included with the body component 102 for use. Thus, the different thread patterns 214 can be altered to accommodate various application rates and medication volumes.
As shown in
In one embodiment, a locking member 400 is positioned on the threaded shank 212 of the screw-like thread component 104. The locking member 400 serves to prevent reverse rotation of the screw-like thread component 104. Thus, the locking member 400 prevents the thread component 104 from being reversely rotated, during use. In one embodiment, the screw-like thread component 104 is rotated in one direction to advance the plunger 108 of the syringe 106. By employing the locking member 400, reverse rotation is prevented and the plunger 108 is not drawn up the syringe barrel 112 and medication 110 is prevented from flowing back up in the syringe 106.
In use, a syringe 106 is filled with medication 110 and the plunger 108 pulled out, creating negative pressure in the barrel 112 of the syringe 106. It should be noted that, if the liquid is thick, a large negative pressure is formed in the syringe 106. The filled syringe 106 is then positioned in the body component 102 and secured via the handle component 120 of the barrel 112 secured within the semi-circular retaining component 208. The screw-like thread component 104 is then screwed into the threaded sleeve fitting 206, such that the threaded shank 212 contacts the push component 130 of the plunger 108. Rotation of the screw-like thread component 104 depresses the plunger 108 on the syringe 106, injecting the medication 110 into the subcutaneous space. Thus, the device 100 allows for a consistent, measured rate of subcutaneous injections via the rotations of the screw-like thread component 104. Further, the thread pattern 214 of the thread component 104 can be altered to accommodate various application rates and medication volumes. By calculating the rotational distance and volume, a consistent administration rate can be achieved, even if the injection is performed at home and/or by a user who is not a trained medical professional.
