The present invention relates generally to medical equipment holders, and more particularly, to a universal holder for safely supporting, securing and organizing a variety of anesthesia and critical care equipment on a single device.
During a variety of medical and/or surgical procedures it is necessary to place a patient under anesthesia to enable performing the procedure, optimize conditions for the surgeon and for the comfort and safety of the patient. In order to do so, it is necessary to utilize a number of different types of anesthesia equipment and accessories. Such equipment may include an invasive pressure monitoring system to monitor the patient's heart and blood pressure, breathing circuits to maintain proper oxygenation and ventilation to the patient and various types of manifolds with multiple ports to control the flow of the medications and hydrating fluids into the heart and blood stream of the patient.
Complications can arise in trying to safely position, organize and secure all the necessary anesthesia equipment in a relatively small area around the head of the surgical operating table supporting the patient and at the intensive care unit critical care bed. For example, the use of invasive pressure monitoring systems having a plurality of pressure transducers is a critical and necessary piece of equipment to monitor a patient's regional and systemic blood pressures. The invasive pressure transducers are typically mounted on a vertical rectangular plate attached to a vertical metal pole or similar structure. The pole and the plate are each and independently, height adjustable to position level to hold and “set” the pressure transducer(s) at a “heart level” of a patient to sample the pressures at the only correct position—at level “CERO”. Put differently, the invasive pressure transducers need to be always “calibrated” at the level of the heart. Any other level position (other than “CERO”) will lead to pressure sampling errors and patient mismanagement. The invasive pressure transducer system (vertical pole, vertical plate and transducers) is attached to the lateral rail of the surgical operating table, which warranties an approximate height of the transducers to be at “heart level” following any height (up or down) change of the operating table. This approximate height level is less accurate if the surgical operating table changes to a steep incline position, head down or head up. The invasive pressure transducer(s) vertical plate can also be free-standing, tedder and unsecured from and over the surgical operating table or ICU bed or attached to a separate structure. In this case, every time the position of the surgical operating table or the hospital ICU bed is adjusted to any position (height or level of inclination), the position of the pressure transducer(s) needs to be continuously readjusted to maintain the pressure transducer at the correct heart level. Failure to do this will cause significant sampling errors, misinterpretations, and mismanagement. Lastly, each separate component of the invasive pressure transducer system (metal clips, vertical pole and vertical plate) may be missing at the time of urgent/emergency assembly or malfunction or brake, disabling the whole system.
The administration of anesthesia also requires the use of an anesthesia breathing circuit composed by a long corrugated breathing tube, filters and varied diameter union connections, including one to the endotracheal tube of the patient. The breathing circuit is typically supported and secured on a “tree” type holder structure that is held and stabilized under the surgical mattress of the operating table. Any change of the surgical operating table position, (height, level of inclination) the “tree” holder structure will move with it while securing the breathing circuit to prevent any tension on the union connections or prevent kinks that may cause a sudden obstruction. Without the tree type holder structure any position change of the operating table, especially extreme inclinations or side rotations needed for robotic surgery, will cause undue tension at multiple points of the breathing circuit, including the vital connection with the endotracheal tube. Furthermore, the malposition or misuse of the tree holder structure can be the cause of endotracheal tube dislodgement despite appropriate means to secure it.
Additionally, complex surgeries such as open cardiac surgery or hybrid surgical procedures such as minimal invasive cardiac procedures with radiology and ultrasound imaging, typically require the use of a transesophageal echocardiography or “TEE.” This continuous imaging modality requires an ultrasound probe which is inserted through the mouth into the esophagus behind the heart. The US probe has a control handle to manipulate various features, including distal maneuvering of the probe like flexion/extension. Thus this control handle has a ring attached to use as a “hanger” to any desired structure which usually is located on a separate intravenous pole adjacent to the surgical operating table. The control handle is typically mounted on a fork clamp holder or a self-made soft aluminum stylet hook or taped to an intravenous pole. Again, if the OR surgical operating table is moved in any direction too far from the control handle when is mounted not in use by the practitioner, the probe will withdraw from the esophagus and completely dislodge from the patient's mouth, which is often difficult to reinsert during the ongoing surgical procedure already with the sterile drapes barrier on and over the patients head.
Critically ill patients requiring surgery and postoperative care in the Intensive Care Unit, often depends upon multiple life-supporting medications at once. It is not uncommon to have limited venous access points to the patient, having the need to use manifolds with multiple ports as a standard to facilitate the delivery of drugs, usually through an indwelling central venous line (CVL) catheter going directly to the heart with a point of entry at the neck. There are many types of manifold designs; nevertheless, all of them can cause significant tension by pulling the CVL when connected to it with all and each of the ports in used with multiple medication lines coming from medical pumps. To resolve this problem and prevent the major complication of suddenly pulling out the CVL, the manifolds are taped to the surgical table mattress, which is ineffective after the tape becomes wet or due to the hours of tension its subjected-to. Also, the manifolds may be secured by an additional clamp mounted on an adjacent IV pole which adds to the overall cost.
In addition to each individual limitation of the above anesthesia equipment relating the patient's position on the surgical table or critical care bed, then, if conjoint together, the risk of interfering or becoming entangled with each other causes further complications.
Accordingly, there is a need for solutions to the aforementioned problems. For instance, there is an established need for a single device that can efficiently and effectively organize and maintain all the necessary anesthesia equipment in a central position close to the head of the patient on the surgical operating table or the ICU hospital bed. There is a further established need for a single device that can be attached to a hospital bed or surgical operating table and is automatically adjustable to compensate for any movement of the hospital ICU bed or surgical operating table to maintain the transducers in the correct position relative to a patient's heart level and to prevent the equipment from becoming dislodged from the patient's trachea and/or esophagus during the procedure.
The present invention is directed to a universal holder for safely supporting a number of anesthesia and critical care equipment in an organized manner on a single device. The universal holder includes a principal structure or main vertical plate having an upper or top portion, a center or middle portion defining a notched channel and a lower portion. Another vertical receiver plate perpendicular to the longitudinal axis of the main plate is movably mounted on the middle portion of the main plate and is vertically adjustable within the notched channel of the main plate to a desired height. The receiver plate includes a plurality of structures for mounting pressure transducers and manifolds. A posterior latch mechanism is provided to secure the receiver plate in a vertical position on the main plate. A transesophageal echocardiogram “TEE” probe mount is provided and is removably attachable to the posterior side of the receiver plate to secure the TEE probe control handle to the universal holder. The universal holder includes a self-adjusting rotational hook to attach the universal holder to a hospital transport stretcher bed and intensive care unit bed. The universal holder also includes a foldable base plate to support and secure the universal holder between the mattress and the frame of the operating surgical table. The upper portion of the main plate includes lateral arms defining gaps for securing breathing circuits, while the bottom portion of the main plate includes projections to hang pressure infusion bags on the universal holder.

The self-adjusting hook or arm 120 is rotatably mounted on the main vertical plate 110 and is provided to be attached to a handrail of a hospital transport stretcher bed or critical intensive care unit bed. The self-adjusting arm 120 rotates relative to the main vertical plate 110 as the handrail moves with the back or upper body portion of the hospital bed, when is raised and lowered in an incline angle. This allows the horizontal receiver plate 112, mounted on the main vertical plate 110, to remain leveled in a proper position relative to a heart of a patient positioned on the hospital bed as also discussed in more detail hereinbelow.
As noted hereinabove, the universal holder 100 is provided to hold a variety of necessary medical anesthesia equipment in a safe and organized manner during a surgical procedure and postoperative care in the critical intensive care unit. For example, the universal holder 100 is designed to primarily hold the horizontal receiver plate 112 to receive invasive pressure transducers 510, a variety of manifolds 800, vital safety sensitive equipment such as breathing circuits 600 and a transesophageal echocardiogram probe handle 700 (not shown). The universal holder 100 may additionally hold multiple infusion pressurized bags as part of the medical equipment needed for invasive pressure monitoring of the patient.
For example, as shown, the horizontal receiver plate 112 contains a plurality of clips 180 as receiver docks for pressure transducers 510 having associated stopcocks 512 with pressurized fluid tubes 514. The breathing circuits 600 may include at least one corrugated breathing hose 610. The variety of manifolds 800, for example, manifold 800 includes separate ports 812 attached to a backing or mounting plate 814 and a tubes or hoses 816 extending between and from the ports 812. The infusion bags 900 include pressure bags 910 having support loops 912 for mounting the pressure bags 912 on the universal holder as discussed hereinbelow.
The main vertical plate 110 is the primary vertical support for the horizontal receiver plate 112 and generally includes a top portion 122 mounting the self-adjusting rotating arm 120, a middle portion 124 defining the notched channel 114 and mounting the horizontal receiver plate 112 and a bottom portion 126 mounting the horizontal base plate 118 when extended. The main vertical plate 110 further includes an extension plate 128 extending from the bottom portion 126 of the main vertical plate 110. A pivot tube 130 is formed between the bottom portion 126 of the main vertical plate 110 and the extension plate 128 of the main vertical plate 110.
As noted hereinabove, the base plate 118 is pivotally mounted to the main vertical plate 110. This allows the base plate 118 to be folded up against the main vertical plate 110 when not in use (see
As shown, the bottom portion 126 of the main vertical plate 110 includes a projecting medial hook 134 extending outward from the bottom portion 126. The medial hook 134 is provided to hold a pressurized infusion bag similar to infusion bags 900. The extension plate 128 also has a pair of projecting lateral hooks 136 and 138 to support the infusion bags 900. Specifically, the lateral hooks 136 and 138 of the extension plate 128 of the main vertical plate 110 are provided to receive the support loops 912 of the pressurized infusion bags 900.
