Abstract
Description
- In medical situations, it is sometimes necessary to isolate a patient to prevent medical personnel or the environment at large from being contaminated by the patient. For example, victims of chemical or biological attacks, and certain infectious diseases require isolation. This isolation system may be in the form of a pod, with gloves provided therein to allow access by the medical worker without risk of contamination. However, these gloves may require replacement due to failure or contamination. A related replacement operation is illustrated in
FIGS. 9A and 9B . During normal operation, aglove 102 is provided in awall 100 of an isolation device, and is disposed on the inside of the isolation device, where a patient is located. Theglove 102 is attached to aflap 104, which is made of a flexible material. During replacement, theglove 102 is pulled to the outside, and portions of theflaps 104 are pulled together below theglove 102 and tied with a rubber band or other sealing member, so that contaminants within the isolation system do not escape to the outside. Theglove 102 is separated from theflap 104, and anew glove 102 is attached to theflap 104. - There are several disadvantages to this operation. First, the
glove 102 and theflap 104 may contain contaminants, yet these elements are exposed to the outside during replacement. Thus, workers must be extremely careful to avoid contamination. This may require protective clothing or modified breathing. However, such preventative measures may not be sufficient. Furthermore, the seal formed by tying theflaps 104 may not be sufficient to prevent contaminants from escaping, especially in light of the small size of biological microorganisms and chemical molecules. Also, this operation is cumbersome and time consuming because it requires several steps (tying anduntying seals 104, removing and replacing gloves 102). In life and death situations, when time is of the essence, patient safety is compromised. Finally, a thick glove is required, degrading the tactile feel sensed by the worker. - To possibly address the above concerns and/or different concerns, the inventors propose an apparatus to interface between an inside and an outside of a sealed environment, including an outer port, and an inner port, disposed in the outer port to provide a seal between the inside and the outside. The inner port is replaceable by a replacement inner port while maintaining the seal during a replacement operation.
- To possibly address the above concerns and/or different concerns, the inventors also propose a chemical or biological containment apparatus having a seal to contain contaminants in an inside thereof from passing to an outside. The apparatus includes an outer envelope, a port disposed in the envelope, the port including an outer portion having a circumferential portion extending away from the envelope and a flange extending from the circumferential portion and attached to the envelope, and an inner portion. The inner portion includes a circumferential surface corresponding to the circumferential portion, a plurality of grooves formed in the circumferential surface, and a plurality of O-rings respectively received in the grooves to form the seal with the outer portion.
- To possibly address the above concerns and/or different concerns, the inventors also propose a method including providing a first inner port to create a first seal between an inside and an outside of a biological or chemical containment device, and replacing the first inner port with a second inner port. The replacing includes pressing the first inner port with the second inner port while maintaining the first seal, and creating a second seal with the second inner port while maintaining the first seal.

-
FIG. 1 is an isometric perspective view of an isolation system 1 including the port system according to one aspect of the invention. The isolation system 1 includes a plurality ofaccess holes 9 to allow access between an inside and outside thereof.Port systems 10 are in theholes 9 and provide for the insertion of devices such asglove 35, which allows a medical worker to operate on a patient. InFIG. 1 , the isolation system 1 is shown as having theglove 35 inserted therein. However, as will be discussed below, a bag, motor, or medical evaluation apparatus may also be inserted in theport systems 10. Furthermore, other devices to allow communication between the inside and outside of the isolation system 1 may be inserted, as well as other devices which allow for the operation of the isolation system 1. Furthermore, the structure of the isolation system 1 is for illustrative purposes only, and the present embodiments of theport systems 10 may be applied to isolation systems 1 having different designs, or other devices which maintain a sealed environment. For example, although the bottom of the isolation system 1 is shown as being formed of different pieces material, it is certainly possible that a single piece of material could function as both the top and bottom. - A patient is placed within the isolation system 1 in order to prevent the spread of an infectious disease or other hazard. Although the isolation system 1 is shown as being open, the system 1 is closed during actual operation. A positive or a negative pressure may be maintained, depending on the nature of the isolation. The outer port may be made of PVC, polyurethane or similar materials.
-
FIG. 2 is a perspective view of anouter port 12 of theport systems 10. Theouter port 12 includes aflange 14 which is in contact with theholes 9, and awall 16 extending outward from theholes 9. Although theholes 9 andouter port 12 are illustrated as having a substantially circular shape, it is noted that different shapes are also possible, provided the integrity of the seal between the inside and outside is maintained. Disposed in thewall 16 arealignment holes 20 which allow for alignment as discussed below. Also in thewall 16 are threadedholes 18 which provide for connection, as discussed below.Slots 22 are also in thewall 16 for alignment, as discussed below. -
FIG. 3 is a perspective view of aninner port 24 of theport systems 10 ofFIG. 1 . Theinner port 24 has an external circumference generally corresponding to the inner circumference of thewall 16 of theouter port 12, to be inserted therein. Theinner port 24 includes a retainingstop 26 in the form of a step, which allows thelock unit 34 to rest against and seal theglove 35 between thelock unit 34 and theinner port 24 at all times. - The
inner port 24 further includes a plurality of grooves 32, each of which receives an O-ring 33. The O-rings 33 contact the inner circumference of thewall 16 and theinner port 24, forming a seal therebetween. As discussed below with respect to the replacement operation, the O-rings 33 are spaced such that this seal is not broken during a replacement operation. Theinner port 24 further includes aslot 30 which aligns with one of the threadedholes 18 to receive a screw, bolt, or other threaded fastening unit passing through the threaded holes 18. Analignment hole 28 is aligned with one of the alignment holes 20 of theouter port 12. -
FIG. 4 is an exploded view illustrating the arrangement of theouter port 12,inner port 24 and theglove 35. Theglove 35 fits between theinner port 24 and alock unit 34, illustrated herein as a locking ring. Thelock unit 34 rests against thestop 26 and there is a very tight fit creating a seal between theglove 35 and the inside wall of theinner port 24. AlthoughFIGS. 1 and 4 illustrate theglove 35 disposed between thelock unit 34 and theinner port 24, other flexible elements may also be inserted therein, possibly to provide communication between the inside and the outside of the isolation system. Another example of such a flexible element is abag 48, as illustrated inFIG. 8 . Thebag 48 includes first andsecond seals bag 48 will be discussed below. -
FIG. 5 illustrates another embodiment of aninner port 36, which may be inserted into theouter port 12. Theinner port 36 is in the form of a solid plug. Thus, asolid face 45 spans acircumferential wall 37. Thesolid plug 36 may be used to seal any of theholes 9 which are not in use. Alternately, as shown inFIG. 5 , medical monitoring equipment (i.e., to measure pulse rate or body temperature) may pass through or be mounted on the face. Similarly, other devices which allow for communication between the inside and the outside (i.e., IV, O2, suction or blood sample lines, or defibrillation lines) may also be mounted on or pass through theinner port 36. - The solid plug may be modified to include two motors in the bottom wall thereof to pressurize/depressurize the isolation system 1. As shown in
FIGS. 6A, 6B , 7A and 7B, a motor and filterport 38 corresponds to the shape of theouter port 12 and includes a similar arrangement of grooves and O-rings on an outside thereof to maintain the seal. The motor and filterport 38 includes anupper half 41 and alower half 39.Holes 40 pass through thelower half 39 and theupper half 41 to receive a bolt or other fastening unit. Thelower half 39 includes amotor cavity 46, wherein a fan motor (not shown) or other type of air-driving unit is disposed.Holes 44 receive a battery (not shown) which drives the fan motor. The battery may have a stepped outer circumference, thus a pill bottle or other cup-shaped element may be inserted into theholes 44 so that the overall shape of theholes 44 and cup conform with the battery, thereby preventing the battery from being inserted backwards. A pressure release valve (not shown) fits into ahole 47 to maintain relative pressure between the inside and the outside of the system 1, for example, in the event of airplane cabin depressurization, or simply to maintain the desired positive or negative pressure under normal circumstances. - As shown in
FIGS. 7A and 7B , theupper half 41 also includes theholes airflow cavity 42 to receive air driven by the fan motor. Afilter hole 43 is provided with a filter (not shown), which filters the air driven by the fan motor. The filter may be either an intake or an exhaust filter. The filter may be a standard HEPA filter or other biological or chemical filter. As shown more clearly inFIG. 7B , thefilter hole 43 may be threaded, so that the filter may be screwed therein with a seal on the bottom surface of the filter. The seal may be rubber or a similar material. The top half may also have grooves and O-rings. - A replacement operation according to the embodiments of the present invention will now be described. As an illustrative example, the replacement of the
inner port 24/glove 35 combination will be discussed. However, the replacement of the other embodiments is similar. The operation begins with the state illustrated inFIG. 1 , in which theglove 35 is already inserted into the isolation system 1, with a seal already existing. It may become necessary to replace theglove 35 with anotherglove 35, for example, if theold glove 35 becomes worn. In such a case, a replacement module is provided, which includes theinner port 24, thelock unit 34 and thereplacement glove 35 all assembled in one unit. The replacementinner port 24 is simply pressed against theinner port 24 that is already in place until the originalinner port 24 drops inside of the isolation system 1. The spacing of the O-rings 33 is such that at some point during the replacement operation, O-rings 33 of bothinner ports 24 are providing seals. Thus, when the seal created by the originalinner port 24 is lost, the replacement seal has already been established. Thus, theglove 35 can be replaced without compromising the seal, or exposing theoriginal glove 35 to the outside environment. Thus, any contaminants on theoriginal glove 35 are not exposed to the outside. Finally, a thinner glove may be used, thereby improving the tactile feel. - With respect to the
bag 48, a similar pressing operation takes place. After thebag 48 is in place, an object (not shown) may be passed to the inside of the system 1 therethrough. Theseal 52 is opened from the outside, and the object is placed between theseals seal 52 is re-sealed, and theseal 50 is opened from the inside (with the glove 35) to introduce the object to the inside. - The invention has been described in detail with particular reference to preferred embodiments thereof and examples, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
- For example, similar continuous seal replacement methods may be employed in connection with glove boxes in nuclear, chemical or biological laboratories, portable laboratories for chemical analysis, incubators, or when working behind protective glass for explosives or lasers.
