The present disclosure generally relates to catheter guide and a method for operating the same.
Central venous catheter is a catheter that is placed into a large vein. Typically, the process involves at least one individual identifying a target location in a patient's body using various imaging techniques, such as, but not limited to, ultrasound imaging. Once the target location in the patient's body is located, the individual may guide the catheter towards the target location. This process typically involves continually monitoring the location of the catheter at various points in the patient's body. This allows the individual to ensure that the catheter is on a correct path towards the target location.
In some embodiments, an apparatus is disclosed herein. The apparatus includes a first portion and a second portion. The first portion has a cylindrical body. The cylindrical body includes a first opening formed therethrough. The opening configured to receive a catheter. The second portion includes a body. The body includes a top surface and a bottom surface. The top surface is substantially parallel to the bottom surface. The bottom surface is configured to contact a skin of a patient. The body includes a second opening formed therethrough. The second portion is coupled with the first portion such that a forty-five degree angle is formed therebetween. The first opening and the second opening form an uninterrupted opening through the apparatus.
In some embodiments, an apparatus is disclosed herein. The apparatus includes a first portion and a second portion. The first portion has a cylindrical body. The cylindrical body includes a first opening formed therethrough. The opening is configured to receive a catheter. The second portion has a body. The body includes a second opening formed therethrough. The second portion is coupled with the first portion such that a forty-five degree angle is formed therebetween. The first opening and the second opening are in fluid communication.
In some embodiments, a method of inserting a catheter is disclosed herein. A user identifies a first location of a target area within a patient's body. The user identifies a second location on a surface of the patient's body based on the first location. The first location is a given depth from the second location. The user identifies a third location on the surface of the patient's body. A distance from the third location to the second location is equal to the depth from first location to the second location. The user positions an apparatus on the surface of the patient's body at the second location. The user inserts the catheter into the first opening of the apparatus. The catheter object enters the patient's body at a forty-five degree angle at the second location.
So that the manner in which the above recited features of the present disclosure can be understood in detail, a more particular description of the disclosure, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrated only typical embodiments of this disclosure and are therefore not to be considered limiting of its scope, for the disclosure may admit to other equally effective embodiments.
To facilitate understanding, identical reference numerals have been used, where possible, to designate identical elements that are common to the figures. It is contemplated that elements disclosed in one embodiment may be beneficially utilized on other embodiments without specific recitation.
One or more techniques described herein are directed to an apparatus for guiding a catheter towards a target located within a body of a patient. As provided above, conventional approaches to placing a catheter within the body of the patient involves a “guess and check” process, by which the individual administering the catheter leverages imaging techniques throughout the process to ensure that the catheter is on a correct path towards the target. Such approach suffers from several limitations. For example, as apparent to those skilled in the art, such process, if performed by a single individual, would involve the individual to operate two different instruments simultaneously. In another example, if the process is performed by two individuals (i.e., one individual administering the catheter and a second individual operating the imaging device), two caretakers are now dedicated to the task at hand. Still further, the guess and check method is not accurate and depends on the individual choosing the correct starting point and starting path towards the target.
The one or more techniques described herein eliminate the above referenced limitations by providing an apparatus that simplifies the catheter administration process. For example, the apparatus disclosed herein provides a means for guiding the catheter towards the target and into the patient's body at a predefined angle. By defining this angle, an operator may be able to identify the insertion point on a surface of the patient's body, such that, when inserted, the catheter is already on a correct path towards the target.
Second portion 104 may include a body 110 having a top surface 112 and a bottom surface 114. In some embodiments, top surface 112 may be substantially parallel with bottom surface 114.
As illustrated, second end 108 of first portion 102 may be coupled with top surface 112 of second portion 104. In some embodiments, first portion 102 may be integral with second portion 104, thus forming a single continuous body 118. For example, apparatus 100 may be three-dimensionally printed as a single unitary apparatus. In another example, apparatus 100 may be formed as a single unitary apparatus using various molding and/or extruding techniques. Generally, first portion 102 may be coupled with top surface 112, such that an angle 116 is formed therebetween. In some embodiments, angle 116 may be approximately 45°.
In some embodiments, apparatus 100 may be formed from a plastic material. For example, apparatus 100 may be formed from a plastic material that is safe for contact with skin. Generally, apparatus 100 may be formed from any material, as long as that material may be safe for contact with skin.
In some embodiments, opening 202 may be sized to receive catheters ranging from about 2.0 mm in diameters to about 9.0 mm in diameter. For example, opening 202 may have a diameter of at least 2.0 mm. Generally, opening 202 may have a maximum diameter. For example, diameter of opening 202 may be sized, such that a catheter, when placed in opening 202, cannot stray from the path defined by opening 202. In some embodiments, diameter of opening 202 may be variable. For example, diameter of opening 202 may taper (e.g., gradually decrease) from first end 106 to second end 108.
In some embodiments, opening 204 may be sized to receive catheters ranging from about 2.0 mm in diameters to about 9.0 mm in diameter. For example, opening 204 may have a diameter of at least 2.0 mm. Generally, opening 204 may have a maximum diameter. For example, diameter of opening 202 may be sized, such that a catheter, when placed in opening 202, cannot stray from the path defined by opening 204.
In some embodiments, opening 202 and opening 204 may include the same diameter. In some embodiments, opening 202 and opening 204 have diameters, such that a diameter of uninterrupted opening 206 tapers from first end 106 to bottom surface 114.
A user may utilize an imaging device 310 to locate target 308 in body 302. In some embodiments, imaging device 310 may be an ultrasound imaging device. By using imaging device 310, a user may be able determine the location and/or depth of target 308 in body 302. Using this information, a user may determine a location 312 on surface 304 that is directly above target 308. Further, the user may determine a depth (“d”) of target 308 in body 302.
Using the depth of target 308, a user may identify an insertion point 314 on surface 304. In some embodiments, a distance, d′, between location 312 and insertion point 314 may be substantially equal to depth, d, of target 308. By identifying insertion point 314 having a distance d′=d, the user now has two sides of a right triangle. Further, by using apparatus 100, the user may ensure that catheter 316 is inserted at insertion point 314 at a specified angle (e.g., 45°). This insertion may create a path 318 from insertion point 314 directly to target 308.
In some embodiments, to aid in identifying a right angle between location 312 and target 308, a user may position imaging device 310 on a skin or surface of the individual, such that imaging device 310 lays flat.
Recall, conventional approaches to placing a catheter involve a user (or another user) to continually monitor the progress of the catheter as it enters the patient's body to ensure that the catheter is on the correct path towards a target in the patient's body. Often times, this results in a user having to guess and check the location of the catheter during its path to a target. The above approach using apparatus 100 eliminates the need for this continual monitoring. Imaging only needs to be performed in the initial stages to identify a location and depth of target 308. This allows the user to use both hands in inserting catheter 316. Further, should a user want to check the trajectory of the catheter, apparatus 100 aids in ensuring that the catheter will pass at least through a field of view of imaging device 310, eliminating any need for the user to guess a current location of the catheter.
Referring back to
In some embodiments, bottom surface 114 may father include a measuring component 404. Measuring component 404 may be representative of a measuring tape that can be folded up and stored within a part of second portion 104.
At step 602, a user may identify a location of a target within a body of a patient. For example, the user may utilize various imaging techniques (e.g., ultrasound imaging) to identify the target within the patient's body. In some embodiments, identifying the location of the target may include identifying a depth (d) of the target from a second location on surface of the patient's body (e.g., skin).
At step 604, the user may identify a third location based on the location of the target and the second location on the surface of the patient's body. For example, the third location may be a distance (d′) from the second location, such that d′=d. In other words, the distance from the second location to the target is approximately equal to the distance from the second location to the third location.
At step 606, the user may position apparatus 100 on the surface of the patient's body at the third location. For example, the user may position apparatus 100 at the third location, such that opening 204 is positioned at the third location.
At step 608, the user may insert an object into opening 202 of apparatus 100. For example, the user may insert the catheter into opening 202 when apparatus 100 is correctly positioned on the patient's body. In this manner, apparatus 100 may ensure that the object enters the patient's body at a pre-specified angle (e.g., 45°).
