Description
- This application is a continuation of co-pending U.S. application Ser. No. 10/858,275, filed on Jun. 1, 2004, which is a continuation of U.S. application Ser. No. 10/350,920, filed on Jan. 24, 2003, which is set to issue as U.S. Pat. No. 6,743,017 on Jun. 1, 2004, which claims priority to U.S. Provisional Patent Application No. 60/393,286, filed Jul. 2, 2002. Each of the foregoing applications are hereby incorporated herein by reference.
- The present invention relates to a device for holding a patient's mouth in an open position during medical, dental and surgical procedures.
- Medical professionals frequently perform procedures that require the patient's mouth to be held in an open position. For example, a patient's mouth must be held open during endoscopic procedures to provide clearance for an endoscope and other instruments. A patient's mouth must also be held in an open or semi-open position when dental bite-wing x-ray images are taken. A similar need exists in trauma evaluation and diagnosis of spinal injuries.
- Spinal injuries require prompt evaluation by emergency health care providers. Early recognition of possible cervical spine injury (CSI) is of critical importance. Spinal injury may be difficult to diagnose in patients who are uncooperative, have altered mental status, or other distracting injuries. In such cases, it is difficult to obtain radiographic imagery to make a proper evaluation of the patient. During the initial assessment, great care must be taken to adequately stabilize the patient's spine and undertake cervical spine radiography for optimal patient evaluation. Obtaining proper cervical spine films, particularly the open-mouth odontoid view (OMV), in the pediatric and adult populations can be a challenging experience even under the best patient circumstances. Patient-related concerns include inability to cooperate during the procedure, repeat films, excessive radiation exposure, and delays in care.
- Data from the National Spinal Cord Injury Statistics Center (NSCISC) reports that approximately 10,000 new cases of cervical spine injury (CSI) occur annually, with 1,100 of these cases occurring in children. Boys sustain injury more often than do girls and the most common type of CSI is a combined fracture and dislocation injury. The primary mechanism by which children sustain this serious injury involves blunt trauma from motor vehicle crashes, falls and sports-related accidents. Children with congenital anomalies such as Trisomy 21, Klippel-Feil syndrome, mucopolysaccharidosis are at a greater risk for CSI due to bony abnormalities of the spine and laxity of the neck and spine ligaments.
- Although CSI in children is rare, it generally carries a greater degree of morbidity and mortality in the younger pediatric population with associated head trauma. Spinal trauma in the young child often occurs in the higher cervical spine area (C1-C3) due to the child's larger head-to-body ratio and laxity of their ligaments. As the pediatric spine matures, it approaches adult-like configuration by around eight years of age, as described in Herman, M. et al., Cervical Spine Disorders in Children, Orthop. Clin. Nor. Amer. 1999, 30(3): 457-465. Although the adult spine can distribute traumatic forces more evenly throughout the cervical vertebrae, they generally have a higher incidence of CSI than children, and sustain primarily lower C-spine injury below the C3 level, as described in Manary, M. et al., Cervical Spine Injuries in Children, Ped. Ann. 1996, 25(8): 423-428.
- It is estimated that 10-25% of patients with CSI suffer extension of their injuries (paralysis or death) from delays in diagnosis, or unwarranted manipulation in the emergency department (ED) setting. Failure to adequately diagnose CSI promptly can lead to severe neurologic disability and morbidity. Two of the more common errors are failure to obtain adequate C-spine roentgenograms and difficulty in x-ray interpretation.
- According to the American College of Radiology Appropriateness Criteria and the American College of Surgeons, the “golden standard” for trauma evaluation of the cervical spine area is the three-view x-ray that includes the lateral, the anteroposterior (AP), and the OMV. See American College of Radiology, ACR Appropriateness, Criteria for Cervical Spine Trauma, 1995: 243-246; American College of Surgeons, Advanced Trauma Life Support (ATLS) Manual, 1997: 217-229. Proper cervical spine x-rays for the evaluation of neck pain and neck injury in both children and adults are critical. However, obtaining the OMV x-rays can be technically difficult and time consuming for both the patient and the emergency health care provider. See Buhs, C. et al., The Pediatric Trauma C-spine: Is the Odontoid View Necessary? J. Ped. Surg. 2000, 35(6): 994-997; Bonadio, W., Cervical Spine Trauma in Children: Part 1. General Concepts, Normal Anatomy, Radiographic Evaluation, Am. J. Emerg. Med. 1993, 11(2): 158-165; Schwartz, D. Introduction to Radiology, “In: Emergency Radiology”, New York: McGraw-Hill, 2000,1-7, 291; Swischuk, L. et al., Is the Open-Mouth View Necessary in Children Under 5 Years?, Ped. Rad. 2000, 30:186-189. Depending on the patient's condition, it may be very difficult to have the patient open their mouth and keep the mouth open while radiography is performed. Problems may be attributed to the patient's age, the patient's mental impairment, unconsciousness, pain or injury that distracts the patient, inability to open the patient's mouth, and difficulties in positioning the patient.
- Accordingly, it is desirable to provide a comfortable oral device that may used in a variety of applications, including radiography, to securely hold a patient's mouth in an open position.
- In light of the foregoing, the present invention relates to a device for maintaining a patient's mouth in an open position during a diagnostic, surgical or other medical procedure. The invention may be used in various applications, including but not limited to, radiology, endoscopy, dental treatment and surgical procedures. In radiology, for example, the invention can be used to facilitate OMV x-rays for spinal trauma evaluation. One or more components of the device are formed of radiolucent materials. In this way, the device may be used in applications such as radiography without visually obstructing x-ray images.
- One or more inner flanges may be provided on the device that extend into the mouth. The inner flange or flanges may engage the interior of the mouth and teeth to hold the mouth in an open position. Grooved or serrated surfaces may be provided on the inner flanges so that the inner flanges are less prone to sliding or slipping as they contact the patient's teeth. The device may also have one or more outer flanges. In one embodiment of the invention, the outer flange or flanges form loop handles that assist in placing the device in a patient's mouth. In another embodiment of the invention, the outer flange or flanges include rests or tabs that support the patient's lips while the device is inserted in the patient's mouth.
- One or more wings may extend from the device to help keep the device in the patient's mouth. In one embodiment of the invention, the wings have solid faces and contain an adhesive pad. The adhesive pad adheres to skin around the patient's mouth when the device is inserted in the patient's mouth to keep the device in place. In another embodiment of the invention, the wings have hollow apertures. Adhesive tape may be wrapped through the apertures and applied to the skin around the patient's mouth to keep the inserted device in place. Alternatively, a flexible strap may be inserted through the apertures and pulled over the patient's head to assist in holding the inserted device in place. The invention will be more fully described by reference to the following drawings.

FIGS. 1-11 generally, andFIG. 1 in particular, a mouth positioning device in accordance with the present invention is shown and designated generally byreference number 10. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts. -
FIG. 1 is a perspective view of themouth positioning device 10. Thedevice 10 is configured to support and maintain a patient's mouth in an open position to permit completion of various medical, dental and surgical procedures. Thedevice 10 may be used in a number of applications, including but not limited to, radiology, endoscopy, dentistry and surgery. In radiology, thedevice 10 can be used in emergency trauma rooms or in free-standing radiology suites. - Referring now to
FIGS. 1-2 , thedevice 10 comprises abody portion 12. The body portion is formed of one or more radiolucent materials that permit passage of radiation or x-rays. In this way, radiographic images can be obtained with the device in place, with minimal obstruction or visible interference from the device. A variety of radiolucent materials may be used, including but not limited to composites and thermoplastics. - The
body portion 12 is formed of a soft, light-weight radiolucent material, such as a soft polymer, composite or thermoplastic. As mentioned above, plastics are radiolucent, which permits them to be used in radiography. Soft plastics also provide sufficient rigidity to support a patient's jaw while offering some flexibility to reduce the stresses that may be exerted on the patient's mouth. Lighter-weight plastic materials also reduce the potential for tooth chipping or damage that could occur when thedevice 10 is inserted quickly, such as in an emergency procedure. Preferably, thedevice 10 is formed of an inexpensive and disposable material, such as polyethylene. - In
FIG. 1 , thebody portion 12 comprises a pair of crescent-shapedwings 14 connected by aloop handle 16. Thewings 14 form a rounded orifice orpassage 17 through which instruments may be inserted during medical procedures. A pair ofinner flanges 20 extend from thewings 14 in a direction that is generally normal to the orientation of the wings. Theinner flanges 20 face one another in a generally symmetrical and oval-shaped configuration that surrounds thepassage 17. As such, theinner flanges 20 are configured to be inserted into the open mouth of a patient. Thebody portion 12 accommodates the insertion of instruments having various sizes. Thepassage 17 may provide an opening up to 80 millimeters wide and accommodate a maximum French size greater than 60. Preferably, thepassage 17 provides an opening that is at least 60 millimeters wide and accommodates a maximum French size of at least 60. - The
inner flanges 20 are configured to contact a patient's teeth in a stable and comfortable position after thedevice 10 is inserted into the patient's mouth. Thedevice 10 is structured so that the patient's teeth engage or clamp down on theinner flanges 20. Preferably, theinner flanges 20 comprise surfaces that grip the patient's teeth and minimize sliding or shifting of thedevice 10 in the patient's mouth. Slide resistant surfaces may be formed in a number of ways. For example, theinner flanges 20 may be molded to provide a contoured or textured surface that frictionally engages the patient's teeth. InFIG. 1 , theinner flanges 20 are shown with a series of ridges orserrations 22 that provide resistance to sliding against the patient's teeth. Alternatively, theinner flanges 20 may be contoured withocclusal recesses 23 that conform generally to the patient's teeth, as shown inFIG. 3 . - Referring again to
FIGS. 1-2 , the loop handle 16 provides a mechanism for handling the device and guiding thedevice 10 into a patient's mouth. In this way, the medical professional avoids direct handling of theinner flanges 20 and other components that are inserted into the patient's mouth. The loop handle 16 forms arounded opening 18 that permits insertion of one or more human fingers. Thedevice 10 may have oneloop handle 16, as shown inFIGS. 1-2 . However, the present invention may also be provided with more than one loop handle. Referring toFIG. 4 , analternate device 110 is shown. The components ofdevice 110 that are similar to components of thedevice 10 are identified by the same reference number plus 100.Device 110 has two loop handles 116 that provide a mechanism for handling and guiding thedevice 110 into a patient's mouth. - For some patients, such as small children, the patient's mouth may be smaller than the outer periphery of the
inner flanges 20. Referring again toFIG. 2 , the loop handle 16 provides a flexible bridge that can be bent to permit insertion of thedevice 10 into the patient's mouth. Thehandle 16 is formed of a thin radiolucent material that flexes to adjust the size of the device as it is inserted into a patient's mouth. More specifically, thehandle 16 is formed of a resiliently flexible material, such as plastic, that bends to permit thewings 14 to be compressed or squeezed together. In this way, thewings 14 andinner flanges 20 can be compressed inwardly as necessary so that the inner flanges fit into a patient's mouth opening. When compressive force is released from thewings 14, the resiliency of the loop handle 16 creates a restoring force that restores the handle, wings andinner flanges 20 to their original positions. Preferably, the resiliency of the loop handle provides a relatively weak restoring force that can be overcome by the jaw strength of most patients. In this way, the loop handle 16 provides a snug fit in the patient's mouth without causing the inner flanges to bear harshly against the sides of the patient's mouth. - Referring again to
FIG. 1 , thedevice 10 is configured to be inserted into a patient's mouth so that thebody portion 12 contacts the facial area around the patient's mouth. Thedevice 10 may be secured in the patient's mouth to prevent the patient from spitting out or removing the device during the performance of medical procedures. This may be desirable in cases where the device is inserted in the mouth of a traumatized or uncooperative patient in need of prompt medical evaluation. Referring toFIG. 2 , thewings 14 comprise a pair ofapertures 15 that extend through the wings. Theapertures 15 may be used with a variety of materials to hold and maintain thedevice 10 securely in the patient's mouth.
