Patent Application
20210330918
This disclosure generally relates to the field of medicine, and, in particular, to an intubation chamber to prevent the contamination of medical personnel.
The claims of this patent, when issued, will be licensed by the inventors and Texas Torque for a nominal royalty payable to Texas Torque. Texas Torque is an organization dedicated to encourage high school students to pursue technical careers. Infectious diseases are commonly spread through direct contact between an infected person and a healthy person through handshaking or kissing, or by indirect contact such as breathing, coughing or sneezing wherein particulates from the infected person are transferred to the healthy person. In an ambulance transferring an infected person to a hospital, or in a hospital, medical procedures such intubations are performed to aid a person who is in respiratory distress to get air into their lungs.
Intubation is a process of inserting a tube, called an endotracheal tube through either the infected person's or patient's mouth or through a cut in the front of the neck into that patient's trachea and securing the tube in place. This is done so that the patient who is in respiratory distress can be placed on a ventilator to assist that patient with breathing. The terms tracheostomy or trach may be used to refer to both the surgical procedure and to the opening created by the procedure.
Often times during the intubation process the patient coughs or sneezes, or even the act of breathing may cause bodily fluids or particulates to be propelled into the air during the insertion of the tube into the patient's trachea dispersing infectious particulates into the atmosphere which can put the ambulance personnel or the doctors performing the intubation at risk of contracting the patient's infectious disease.
Conventional chambers used to prevent the spread of infection during patient intubation are typically a box type device made of polycarbonate or other transparent material, that is placed over a patient with arm ports for a doctor or medical technician to perform an intubation procedure. The disadvantage of this box type design is that a doctor or medical technician is unable to get close enough to the patient to observe the interaction of the laryngoscope or other instruments with the tongue, epiglottis, larynx, vocal cords, trachea and airways of the patient in order to easily perform the intubation process.
Embodiments of the disclosure may be better understood by referencing the accompanying drawings
The description that follows includes example systems, methods, and techniques that embody embodiments of the disclosure. However, it is understood that this disclosure may be practiced without these specific details. For instance, this disclosure refers to the use of an intubation chamber to prevent the spread of infectious diseases from an infected patient to medical personnel using angled sides and/or in illustrative examples. However, depending on the manufacturing procedures embodiments of this disclosure can also be used wherein the edges are curved using for example blow molding. In other instances, well-known manufacturing processes, protocols, structures and techniques have not been shown in detail in order not to obfuscate the description.
While the aspects of the disclosure are described with reference to various implementations and exploitations, it will be understood that these aspects are illustrative and that the scope of the claims is not limited to them. Many variations, modifications, additions, and improvements are possible.
Example embodiments include a device that can be placed over a patient so that the infectious particulates expelled by the patient during the tracheostomy or intubation process are contained and not transmitted to ambulance personnel or the doctors performing an intubation or tracheostomy.
Referring to the drawings,
In some embodiments, intubation chamber 10, and in particular enclosure member 30 may comprise a back member 100 comprising a sealable opening 60 with a curtain 61. Back member 100 may be coupled to upper member 90. In some embodiments, the angle between back member 100 and upper member 90 is ninety (90) degrees. In other embodiments the angle between back member 100 and upper member 90 may be greater than 90 degrees. The sealable opening 60 seals against the torso of the patient that is being intubated using gasket 63 or other sealable means such as an inflatable seal, curtains and the like. Curtain 61 can be composed of plastic, preferable a transparent plastic, though other sealable materials may also be used. Enclosure member 30 may further comprise a left side wall 70. Left side wall 70 may comprise a nozzle 71, preferable with a back flow preventable valve, that is used to couple to a suction pump, not shown, to maintain a negative pressure within the intubation chamber 10. This negative pressure creates a vacuum within intubation chamber 10 to suck out of the intubation chamber 10 any infectious particulates that may contaminate the medical personnel performing the intubation procedure.
In some embodiments of the intubation chamber 10, the enclosure member 30 further comprises a right side wall 50. In some embodiments, the left side wall 70 and the right side wall 50 are inwardly bent at an angle of less than 90 degrees and preferably 85 degrees with the base of intubation chamber 10 as shown in
In some embodiments, the bottom end of the intubation chamber 10 comprises a bottom end gasket 80 to seal the intubation chamber 10 to a gurney or table, not shown. In particular, the bottom end of intubation chamber 10, i.e., the left sidewall 70, right side wall 50 and vertical member 20, will have a gasket to seal with the gurney or table. In some embodiments, gasket 63 of sealable opening 60 of back member 100 of the intubation chamber 10, seals against the body of a patient that is being intubated using an inflatable seal. The bottom end of the intubation chamber 10 is open so that the chamber can be lifted and placed onto a patient that is lying on a table or gurney. The material used for gasket 63 and gasket 80 may be elastomeric materials or other well-known sealable materials. In some embodiments, the seal between intubation chamber 10 and the patient may be accomplished by coupling one or more straps, not shown, from the intubation chamber 10 to the table. In other embodiments, the strap may be passed from the intubation chamber 10, under a patient's body, or under the table on which the patient is laying and coupling the strap to the other side of intubation chamber 10 so that the gasket 63 fits snugly to the torso of the patient being intubated. Thus, the bottom end of gasket 80 coupled with gasket 63 of the intubation chamber 10, and/or curtain 61 forms a seal around the patient so that any infectious airborne particulates are suctioned out through nozzle 71 of intubation chamber 10, thereby keeping the medical personnel performing the intubation from being infected.
In some embodiments, the vertical member 20 has dimensions of approximately ‘h’=11.5 inches height. In some embodiments, the minimum height of the vertical member 20 is limited by the diameter of arm ports 21. In some embodiments, the arm port 21 is at least 3 inches in diameter. In some embodiments, the width ‘w’ of the intubation chamber 10 is limited by the width of the gurney or table on which the patient lays during the intubation procedure. In some embodiments, the width ‘w’ is 30 inches. In some embodiments, the length 1′ of the intubation chamber 10 is 22.5 inches.
The enclosure member 30 can include an upper member 90 coupled to back member 100 and to transparent angled member 40. In some embodiments, the angle Theta Θ between the upper member 90 and the transparent angled member 40, as shown in
In some embodiments, the left side wall 70, and the right side wall 50 of enclosure member 30 has inwardly sloping walls. As shown in
In some embodiments, the left side of vertical member 20 has a handle 72, and/or one or more bar handles 75 coupled thereon. Correspondingly, the right side of vertical member 20 may have a handle 52, and/or one or more bar handles 55 coupled thereon. In some embodiments, the bar handles couple the vertical member 20 to the back member 100 to enable a single individual to lift and move the intubation chamber 10 as necessary.
In some embodiments, the enclosure member 30 is coupled to vertical member 20 and transparent angled member 40 using methylene chloride based acrylic cement or plastic solvent. In other embodiments, the blow molding technique may be used to form the integrated enclosure member 30 comprising one or more of the discrete parts that includes upper member 90, back member 100, left side wall 70, right side wall 50, vertical member 20, and transparent angled member 40. In some embodiments, vertical member 20 and back member 100 may be inwardly sloped for example, to ensure stacking of multiple units for storage or shipping. In some embodiments, transparent angled member 40 may be coupled with the integrated enclosure member 30 using means well known in the art for example methylene chloride based acrylic cement or plastic solvent, hook and slots, press fitting, etc. In some embodiments, integrated enclosure member 30 may include angled member 40 so long as the angle Theta as described above is maintained. In some embodiments, the transparent angled member 40 and upper member 90 may have tabs and slots that are alternately spaced between the transparent angled member 40 and upper member 90 to prevent bowing or sagging as is well known in the art. Tabs and slots or other stiffening means may be employed between other members as well to prevent bowing or sagging.
In some embodiments, the transparent angled member comprises a lens for example a convex lens, or a Fresnel lens see
Vertical member 20 can include handles 72 and 52 on the left and right side respectively of vertical member 20 as shown. Bar handles 75 and 55 extend backwardly from vertical member 20 toward the back member 100, not shown, and make it possible for a single individual to lift and move intubation chamber 10.
At block 802, the intubation chamber 10 (having a transparent angled member 40 coupled to a vertical member 20, and an enclosure member 30) is placed over a patient. Operations of the flowchart 800 can include coupling a suction pump, not shown, to a nozzle 71 on the intubation chamber 10. The nozzle 71 can prevent the air from a suction pump to back flow into the intubation chamber 10.
At block 803, a determination is made of whether the suction pump is connected to the nozzle 71. If the suction pump is not connected, operations of the flowchart 800 continue at block 804. Otherwise, operations of the flowchart 800 continue at block 805.
At block 804, the suction pump is connected to nozzle 71. Operations of the flowchart 800 continue at block 805.
At block 805, the suction pump is activated.
At block 806, a determination is made of whether the pressure within the intubation chamber has been reduced to at least a threshold level. For example, the threshold level can be the atmospheric pressure outside the intubation chamber. In some embodiments, the threshold level can be a negative pressure such that any contaminants within the intubation chamber 10 removed the intubation chamber via the suction pump. This also ensures a vacuum seal between the intubation chamber, the patient, the users of the intubation chamber, and the table on which the patient is laying. In some embodiments, the inflatable seal referred to in
At block 807, intubation is started. For example, intubation can be started by a user reaching through the vertical member 20 via one or more arm ports 21 to intubate the patient.
