Abstract
A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.
Description
- This application is a continuation of U.S. patent application Ser. No. 16/578,072, entitled “ONE-TIME PRIMING IV INFUSION EXTENSION SET,” filed Sep. 20, 2019, the disclosure of which is incorporated herein by reference in its entirety.
- The present disclosure relates generally to IV extension sets for conveying at least two medicinal fluids to a patient independently from one another. More specifically, the present disclosure relates to an IV extension set having multiple tubing branches capable of being simultaneously primed.
- Infusion IV sets are generally used in infusion therapy in order to deliver medication from a pre-filled container, e.g., an IV bag containing the desired medication, to a patient. Generally, the IV tubing is connected to a catheter which is inserted into the localized area to be treated. In some cases, there is a need to deliver multiple medications to the patient in potentially differing dosages, thereby causing the need for an IV extension set having multiple branches of tubing through which the multiple medications may be dispensed to the patient.
- The description provided in the background section should not be assumed to be prior art merely because it is mentioned in or associated with the background section. The background section may include information that describes one or more aspects of the subject technology.
- Before infusion of medications through an IV extension set, it is desirable to prime each of the multiple tubings of the IV extension set in order to remove air from the inside of the tubing that may end up producing air bubbles in the medication to be delivered. It is desirable to remove air from inside the tubing because the air could become trapped as air bubbles in the medicinal fluid, thereby causing incorrect (e.g., too little) dosages of medication to be dispensed to the patient through the tubing.
- Due to the multiple branches of tubing in many IV extension sets, for example the IV extension set illustrated in
FIG. 1 described below, the practitioner connects a syringe to the adapters of each of the branches of tubing, one at a time, in order to prime each of the multiple tubings (one at a time as well). Since each of the branches of tubing of the traditional IV extension set is primed individually (one at a time), the priming process can be time consuming, especially if the extension set has several branches. As a result, the overall priming process of the some multi-tubing IV extension sets (e.g., illustrated inFIG. 1 below) may be somewhat inefficient.
Accordingly, there is a need in the field for a one-time priming IV extension set, which is configured such that a syringe having priming fluid only need be connected to one of the multiple tubing branches in order to prime all tubing branches of the extension set at once.
In accordance with various embodiments of the present disclosure, a multi-tubing intravenous (IV) extension set may include an outlet tubing, a primary inlet tuning, at least one secondary inlet tubing, and a slide clamp positioned on the outlet tubing. The outlet tubing may have a proximal end fluidly coupled to a primary multi-tubing connector and a distal end configured to be fluidly coupled to a vascular device for patient. The primary inlet tubing may have a proximal end having an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The at least one secondary inlet tubing may have a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. The slide clamp may be configured to restrict fluid flow between the proximal and distal ends of the outlet tubing in a closed configuration to cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction and flow into the at least one secondary inlet tubing via the primary multi-tubing connector. - In accordance with some embodiments, a method of simultaneously priming a plurality of tubing branches of a multi-tubing intravenous (IV) extension set having a primary inlet tubing fluidly coupled to a primary multi-tubing connector, at least one secondary inlet tubing fluidly coupled to the primary multi-tubing connector, and an outlet tubing fluidly coupling the primary multi-tubing connector to a vascular device is disclosed. The method may include connecting a syringe to an adapter of the primary inlet tubing, and pinching, bending, or otherwise folding a slide clamp positioned on the outlet tubing to block fluid flow between the proximal and distal ends of the outlet tubing. The method may further include depressing a plunger of the syringe in order to force priming fluid from the syringe downstream through the primary inlet tubing and into the outlet tubing via the primary multi-tubing connector, and reversing flow of the priming fluid to flow back upstream through the primary multi-tubing connector and into the at least one secondary inlet tubing. Air existing in the at least one secondary inlet tubing may thus be vented out of the at least one secondary inlet tubing by flowing the priming fluid therethrough.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the subject technology as claimed. It is also to be understood that other aspects may be utilized, and changes may be made without departing from the scope of the subject technology.

Various aspects of the subject technology will now be disclosed according to particular but non-limiting examples. Various embodiments described in the present disclosure may be carried out in different ways and variations, and in accordance with a desired application or implementation.
- The present invention is generally directed to tubing extension sets used in the administration of fluids to a patient that are commonly referred to as intravascular (“IV”) extension sets. More particularly, various embodiments of the present disclosure are directed to a one-time priming IV extension set, which is configured such that a syringe having priming fluid only need be connected to one of the multiple tubing branches in order to prime all tubing branches of the extension set at once. Furthermore, various embodiments of the present disclosure are directed to an IV extension set having an air stop membrane that can be included within or otherwise attached to the IV extension set prevent air bubbles from accumulating in the multiple tubing branches of the IV extension set. An IV extension set according to the various embodiments of the present disclosure is used broadly herein to describe tubing sets, which may be used in the arterial, intravenous, intravascular, peritoneal, and non-vascular administration of fluid. Additionally, the IV extension sets of the various embodiments described herein may be used to administer fluids to other locations within a patient's body.
- One common method of administering a plurality of fluids into a patient's blood flow is through an IV set having a plurality of tubing branches, as illustrated in
FIG. 1 . As depicted inFIG. 1 , the IVset 10 generally includes a plurality oftubing branches tubing branches connector 12 for attachment to a catheter (not shown) that may be positioned intravenously in the patient. As illustrated inFIG. 1 , the IV extension set 10 may also includeadapters individual tubing branches - Before infusion of the medications through the IV extension set, it is desirable to prime each of the multiple tubings of the IV extension set in order to remove air from IV sets such as the IV extension set 10, which access a patient's blood flow. This is desirable for example, because air from the inside of the tubing branches may end up producing air bubbles in the medication to be delivered, thereby causing incorrect dosages of medication to be dispensed to the patient through the tubing. While this is a concern when accessing arterial blood, it is also a concern when accessing the venous side. Specifically, if air bubbles are allowed to enter a patient's blood stream while receiving the intravenous administration of fluids, the air bubbles can form an air embolism and cause serious injury to a patient.
- For the majority of the adult population, the right atrium and the left atrium may be completely separated from each other so that the blood and air bubbles are moved from the right atrium, to the right ventricle, and then to the lungs where the air bubbles may be safely vented. The bubble-free blood may then be returned to the left atrium, where the blood is moved to the left ventricle and then sent throughout the body. However, in some cases, such as with infants and in a portion of the adult population, the right atrium and left atrium are not completely separated. Consequently, air bubbles travelling along with the medicinal fluid in each of the
tubing branches - In spite of the importance of removing air bubbles while priming an IV set for use in the intravenous administration of fluids, the complete removal of air bubbles can be a time consuming process. For example, due to the multiple branches of tubing in traditional IV extension sets, for example the IV extension set illustrated in
FIG. 1 described below, the practitioner connects a syringe to each of theadapters respective tubing branches tubing - The priming process using a conventional IV set such as the IV extension set 10 may also lead to contamination of the IV set by inadvertently touching a sterile end of the IV set. Typically, when the IV set 10 is primed, clamps 27 may be closed to prevent fluid from moving from a drip chamber (attached to the IV bag) through the
individual tubing branches clamp 27 on therespective tubing branch individual tubings end 14 of the IV set 10. - This conventional priming process, however, typically leads to the aforementioned air bubbles being trapped in the
tubing branches tubing branches tubes tubing respective tubing - Additionally, air bubbles may be generated as drops of fluid strike the surface of the pool of fluid within the drip chamber. These air bubbles can be pulled into the tubing of the IV set from the drip chamber. This problem may be aggravated in pediatric applications where the drip orifice may be smaller which may result in increased turbulence.
- To remove air bubbles from the IV set, fluid from the IV bag or bottle is allowed to flow through the
tubing tubing - Another debubbling method is to directly remove air bubbles from the IV set. For example, if the IV set includes connectors, e.g.,
connector 25 along the length of thetubing connector 25 using a syringe. - In some examples, in order to address the difficulties of removing bubbles from an IV set, various prior art IV set designs have employed a membrane for filtering air from the fluid as it flows through the IV set. For example, oftentimes a membrane may be placed in the bottom of the drip chamber so that fluid flowing out of the drip chamber must pass through the membrane. The membrane can be configured to allow the passage of fluid while blocking the passage of air. In this way, bubbles are restricted or prevented from passing into the tubing leading to the patient. Similarly, a membrane can be included in the connector that couples the tubing to a catheter to block any air present in the tubing from passing into the patient's vasculature.
- The use of air filtering membranes in these prior art IV set designs have been beneficial. However, even with the use of these membranes, various drawbacks still exist. For example, if an IV fluid bag is allowed to empty, all of the fluid within the IV set will pass through the IV set and into the patient leaving the IV set full of air. Once this occurs, the IV set will have to be re-primed to remove the air from the IV set before a new fluid bag can be administered. To avoid having to re-prime the IV set, clinicians will therefore have to be present as a fluid bag is emptying to ensure that the fluid bag can be replaced before the drip chamber empties. Also, if the clinician does not notice that air has entered into the tubing, he or she may fail to re-prime the IV set when connecting a new fluid bag. This may result in air passing into the patient once the new fluid bag is administered.
- The one-time priming IV extension sets 100, 200, and 300 and associated methods of the various embodiments described herein overcome the shortcomings of traditional or conventional IV sets such as the IV extension set 10 described above. For example, various embodiments of the present disclosure are directed to providing a one-time priming IV extension set, which is configured such that a syringe having priming fluid only need be connected to one of the multiple tubing branches in order to prime all tubing branches of the extension set at once. Accordingly, all branches of tubing may be simultaneously primed, leading to a quicker, more efficient priming process. Furthermore, various embodiments of the present disclosure are directed to an IV extension set having an air stop membrane that can be included within or otherwise attached to the IV extension set to prevent air bubbles from accumulating in the multiple tubing branches of the one-time priming IV extension set. Accordingly, the IV extension sets 100, 200, and 300 of the various embodiments described herein advantageously allow for venting of air bubbles which may be present in the multiple tubing branches without the potentially disadvantageous result of contamination of the tubing occurring as described above with respect to priming the traditional or conventional IV extension sets.

FIG. 2A illustrates a one-time priming multi-tubing IV extension set 100 that includes ahydrophobic filter 110 in a body of anadapter 120 ofsecondary tubing FIG. 2A , a multi-tubing intravenous (IV) extension set 100 for conveying at least two medicinal fluids independently from one another may include aprimary inlet tubing 126 having a proximal end coupled to anadapter 140 for connection to a syringe 150 (illustrated inFIG. 2B ) containing a fluid such as a priming or medicinal fluid. Theprimary inlet tubing 126 may further include a distal end coupled to a primarymulti-tubing connector 118. The primarymulti-tubing connector 118 in the various embodiments described herein serves the purpose of fluidly connecting theprimary inlet tubing 126 and any additional secondary inlet tubing, e.g., inlet tubings 122 and 124 to acommon outlet tubing 128 leading to the patient. In particular, in some embodiments, theoutlet tubing 128 may have a proximal end coupled to an end of the primarymulti-tubing connector 118 which is opposite to the end to which theprimary inlet tubing 126 and thesecondary inlet tubings outlet tubing 128 may also have a distal end configured to be fluidly coupled to a vascular device for patient (not shown). Accordingly, theoutlet tubing 128 may be coupled to adistal end adapter 130, for example a Luer adapter, which connects to an IV catheter (not shown) to be inserted at a target region on the body of a patient for delivery of the medicinal fluids. -
FIG. 2A depicts a configuration having more than onesecondary inlet tubing secondary inlet tubings multi-tubing connector 118 via a secondarymulti-tubing connector 116. In particular, thesecondary inlet tubings intermediate tubing 117 via the secondarymulti-tubing connector 116. Theintermediate tubing 117 may have a proximal end coupled to a distal end of the secondarymulti-tubing connector 116 and a distal end coupled to the proximal end of the primarymulti-tubing connector 118. In particular, as depicted, distal ends of thesecondary inlet tubings intermediate tubing 117 via the secondarymulti-tubing connector 116. - However, the various embodiments described herein are not limited to the aforementioned configuration. Instead, in some embodiments, the multi-tubing IV extension set 100 may include only one secondary inlet tubing. In these embodiments, the sole secondary inlet tubing may be directly coupled to the primary multi-tubing connector 118 (i.e., without the need for a secondary
multi-tubing connector 116 to be interposed therebetween) for fluid communication with theoutlet tubing 128. - In accordance with various embodiments, the at least one
secondary inlet tubing adapter 120 for receiving a medicinal fluid. For example, each of thesecondary inlet tubings adapter 120, as previously described above. As such, the medicinal fluid may be dispensed from the IV bag or syringe to thesecondary inlet tubing adapter 120. In some embodiments, eachadapter 120 of the at least onesecondary inlet tubing tubular body 121 including anouter surface 123 and an inner surface defining a lumen therethrough. Thus, theadapter 120 may be in the form of a hollowtubular body 121. As depicted, thebody 121 of theadapter 120 may include at least oneair vent 110 disposed thereon and extending from the inner surface to theouter surface 123 of the body.
