Description

[Technical Field]

[0001] The present invention relates generally to personal protection systems. More particularly, the present invention relates to a personal protection system. The system includes a helmet and a removable hood. The hood is attached to the system. The device has buttons that are actuated to control its operation. [Background technology]

[0002] During medical and surgical procedures, medical personnel use assemblies known as personal protective systems. This type of assembly may include a helmet. However, it is placed over the helmet to at least cover the wearer's head. A garment that extends to or below the waist is sometimes called a hood. The garment in question is called a gown or toga. The fabric forming the garment is designed to protect the healthcare worker from the surrounding environment. The face shield is designed to provide a barrier between the patient and the operating room. It is the transparent part of this barrier that allows you to see where it is being used.

[0003] Barriers provide benefits to both patients and healthcare professionals. Barriers can occur during surgery. Virtually eliminates the possibility of healthcare personnel coming into contact with fluids or solid particles from the patient. Every healthcare professional inevitably encounters microscopic and near-microscopic necrotic skin cells, sweat droplets, and saliva. The barrier provided by the personal protective system is This virtually eliminates the possibility of the material being deposited on the patient's normally concealed tissues. Limiting the exposure of a patient's internal tissues to the material so that the material does not cause infection in the tissue This will similarly reduce the likelihood of this happening.

[0004] If a healthcare worker simply wears a garment over their head, the inevitable impact on their breathing will be felt. As a result, carbon dioxide and water vapor will inevitably accumulate within the garment. Even so, medical personnel, especially those performing surgery, are subject to the adverse effects of excessive carbon dioxide exposure. If moisture vapor accumulates in the garment, it will travel to the face. These droplets will condense on the inside of the face shield. This may reduce visibility into the

[0005] The undesirable accumulation of carbon dioxide and water vapor within the garment of a personal protective system To avoid undesirable results, the fan is attached to the helmet of the personal protection system. The fan blows fresh air into the space within the garment, specifically around the head of the person wearing the system. This air contains carbon dioxide and water vapor. The system forces the air out of the wearer's head. An example of such a system is US Pat. These are described in references 1 and 2, both of which are incorporated herein by reference. All of these personal protection systems shall be fitted with a protective device around the wearer of the system. Provides a barrier to prevent unwanted buildup of carbon dioxide and water vapor within the garment It has become.

[0006] The personal protection system shall have at least one or more control buttons or switches. At a minimum, most personal protective systems have a control that is depressed by the wearer of the system. A button is provided that allows the wearer to control the speed of the fan. This is desirable because the wearer usually needs the fan to ensure the environment inside the hood is You want to set the fan to run at a high enough speed that it is comfortable for you. At the same time, the wearer may notice that the noise generated by the fan significantly reduces their ability to concentrate on the ongoing operation. You don't want to set the fan to run at such a high speed that it interferes with the operation. A supplementary device may be attached to the helmet of the personal protection system. The wearer may be exposed to the light source during some procedures. It has been found to be useful for illuminating tissue in the surgical field. One reason it is useful is that it allows you to observe the color of tissue and determine the type and / or health of the tissue. The helmet of the personal protection system Another type of auxiliary unit that may be attached to a computer is a unit with a microphone. Some of these units are radio transceivers. Therefore, the person wearing the personal protective system must not be exposed to other personnel in or outside the operating room where the surgery is being performed. This is useful because it allows communication with the person wearing the personal protection system. When used, the presence of a hood over the wearer makes it difficult to speak loudly to be heard. As an alternative unit with a microphone, an amplifier and a loudspeaker. The user can speak through the hood to the surrounding environment. Even if a person wearing a personal protection system talks by normal voice, the sound will not be heard around the head of the person wearing the system. Other means can be provided to ensure that the device can be heard through the existing hood. Cut.

[0007] Each of these devices typically requires the wearer of the personal protective system to determine the operational status of the device. It has one or more buttons so that it can be controlled. The fan includes at least one control button for controlling the speed of the fan. If the helmet is equipped with a light source, a button for controlling the on / off state of the light source is provided. If the helmet transmits speech as radio waves or simply amplifies and transmits the speech, If your device has a built-in controller, it will typically have a button that controls the on / off state of this assembly. It will be established.

[0008] Also, as disclosed in Patent Document 3, some personal protection unit helmets: These documents are incorporated herein by reference. These cooling means are typically one or more Peltier cooling modules. When this type of helmet is worn, the heat dissipation part of the cooling module The module is designed to be adjacent to, if not in contact with, the wearer's skin. When the clothing is moved, it takes away the heat energy from the wearer. The personal protection system can easily maintain the wearer's body temperature within a comfortable range. When a system includes one or more of these cooling modules, the system typically One or more devices that allow the wearer to customize the rate at which the module removes heat from the wearer. It has multiple buttons.

[0009] In one current practice, one or more buttons associated with a personal protection system are Once the personal protection system is donned, the button It will be covered by the hood portion of the garment. Patent Document 4, which is related to a personal protection system in which a control button is attached to the outer surface of a helmet, More specifically, these buttons are positioned above and in contact with the helmet wearer's ears. The helmet is attached to the rear of the helmet. When the wearer wishes to press the ear, the wearer must move the hand outside the sterile field to a position above the ear. (The sterile field is generally the anterior space between the waist and neck of the person wearing the garment.) If the button is located near a suspended device such as a light source, when you move your hand to the button, Care must be taken to ensure that the hand does not inadvertently come into contact with the light source. If this occurs, the wearer's hands, even if gloved, cannot be considered sterile. This would result in an interruption in the operation as the gloved person puts on the gloves again.

[0010] Having to position your hand in that way to press the button creates additional discomfort. This occurs because these buttons are located adjacent to the ears. This is because the helmet is out of the wearer's line of sight, making it difficult to accurately press the button. This means that the wearer cannot rely on visual cues to position themselves in the right position. When this type of system is used, some surgeons prefer to have the procedure performed by a circulating nurse outside the sterile field. This may involve pressing a control button to adjust the operational status of the personal protective system. This will help the surgeon who must focus on proper hand placement to perform the procedure.

[0011] The lack of these visual cues also makes it difficult for the surgeon to automatically press the desired control button. This potential confusion can make it difficult to press the button with confidence. The limited number of control buttons that tend to be mounted on the helmet of the protection system A limited number of buttons limits the number of control options available to the wearer of the system. Limited.

[0012] The aforementioned patent document 2, which is incorporated herein by reference, discloses a method for manufacturing a chin bar having a button at the bottom portion of the chin bar. The present invention discloses a personal protection system that can be attached to a chin bar that extends downward from the shell. Helmets typically have a U-shaped structure, with the chin bar on either side of the face when worn. The chin bar is designed to extend downwardly from a position spaced outward and forward of the The device includes an at least semi-rigid beam that is positioned in front of the wearer's chin and somewhat The primary purpose of the chin bar is to provide structural support for the face shield. More specifically, the chin bar prevents the face shield from contacting the face of the user wearing the personal protective system. It is a structural element of the helmet that prevents it from sliding inwards relative to the The system has fastening elements attached to the face shield that temporarily hold the garment to the helmet. Many of these personal protection systems are designed to be integral with the chin bar. The fastening elements engage complementary fastening elements attached to the face shield of the garment. , is designed.

[0013] When the control button is attached to a chin bar, the button is often located below the wearer's chin. The button is located within the web of the bar. The wearer who wishes to press the button must Press the button by lifting your face and pressing on the part of the garment that covers the button. The advantage of positioning the control button in this way is that the wearer wishing to press the button The advantage is that the hands are not moved to positions that are clearly outside the sterile field. The hand is substantially in front of the wearer's face during the process, so that the hand is within the wearer's field of vision. Relying at least in part on vision, the user must quickly and accurately position their hands and You can press the target button.

[0014] Considering its relative accessibility, it is recommended to use a control button mounted on the chin bar. Personal protection systems are generally easier to use alternatives to their predecessors. Nevertheless, in some surgical procedures, significant amounts of fluid are expelled from the patient toward the wearer. These fluids may contain irrigation fluids contaminated with blood and other fluids. Small tissue particles may also be expelled from the patient. When this material is expelled, If the system functions as intended, the fluid will not come into contact with the skin or clothing of the person wearing the system. Instead, it attaches to the garment. The wearer wishes to press a button attached to the chin bar. The problem is that the part of the garment that has fluid on it must be pressed. Such pressure from the thumb or fingers may also allow fluids or other contaminants to penetrate the garment. To ensure this, it is actually much easier than some traditional commercial garments. The garment must be made from a less permeable material. They are less breathable than traditional garments. This loss of breathability can be felt over time. Over time, this can cause discomfort to the wearer of the personal protective system. This material is more expensive than the materials used to make prior art garments. Constructing the garment from this expensive material increases the cost of the garment.

[0015] Additionally, some personal protection systems require the user to connect a battery pack to the helmet. The fan is configured to be activated as soon as the garment is attached to the helmet. This occurs even if the fan is not positioned over the head and the seat. This will result in unnecessary noise and the operation of the fan will not serve any useful purpose. This will result in a loss of charge stored in the stem battery. [Prior art documents] [Patent documents]

They are in emotional contact.

[0045] The user first installs the personal protection system of the present invention by putting the helmet 32 ​​on his or her head. Prepare the helmet 30 for use. If necessary, connect the battery 86 to the helmet. The garment 102 is then placed over the helmet 32 ​​and at least the user's head. Again, in the case of the toga style garment 102, the garment is placed around the arms. The garment will cover the user and extend at least to the waist. As part of the garment, the face shield is folded around the front of the shell rim 36. 10, garment magnets 148a, 148b, and 148c are respectively connected to complementary helmet magnets. By pressing against the stones 64a, 64b, 64c, the device is releasably fixed to the helmet. will be done.

[0046] The magnets 64a, 64b, 64c and 148a, 148b, 148c are arranged in contact with each other. Since these are made of a magnetic material, the magnet pairs that come into contact with each other An electrical connection is made between the pair of magnets, optionally magnets 64c and 148c. This shows the garment 102 being releasably attached to the helmet. As a result, the buttons 120 and 134 are connected to the conductors 124, 128, and 144, and the magnets 148 and 144. , and via conductor 82, electrical connection to detector 85 has been achieved. .

[0047] Thus, the user can operate the system 30 by pressing buttons 120 and 134. In this aspect of the invention, the user can touch button 120 by touching button 134, the motor / fan speed is reduced. Motor / Fan Speed ​​Increased. The user can increase the speed of the fan 94. When a user wishes to activate the button, the user moves the finger towards one of the buttons, optionally button 120. The face shield 110 on which the disk 122 and ring 126 of the button 120 are formed The presence of the finger on this area changes the dielectric constant characteristics between the disk 122 and the ring 126. This changes the capacitance of the button 120. Again, the detector 85 detects the The variation in the characteristics of the signal across the conductive disks and rings that form each of the channels 120, 134 The face shield 110 is continuously monitored for changes in the face shape and the amount of pressure applied to the face shield 110. When the capacitance changes as a result of the button being pressed, the disk 122 and ring A change in the characteristics of the signal crossing the loop 126 occurs. In response, detector 85 outputs a signal to controller 88 indicating that this signal has occurred. The controller 88 receives this signal to allow the user to control the speed of the fan 94, and in fact the speed of the motor 92. This allows the controller 88 to adjust the motor, and therefore , and the energization signal applied to the motor 92 to rotate the fan 94 at a higher rotation speed. This will reconfigure the characteristics of the system.

[0048] In this aspect of the invention, the user presses the button 134 in the area of ​​the face shield where it is formed. Placing a finger nearby will decrease the fan speed. The change in capacitance across the disk 136 and ring 142 is detected by the detector 85. This would be interpreted as an indication that the speed of the data processor 92 should be reduced.

[0049] When a user of the system 30 of the present invention desires to set a system state, he or she presses the appropriate button. The user presses against the area of ​​the face shield that forms the garment 120 or 134. In other words, there is no need to press on the fabric part to change the system state. The user places their fingers on the non-porous components of the face shield 110. The liquid is released by pressing a finger on the button to change the system state. There is no need to worry about the material seeping into the porous parts of the ment. The user must press the button when there is body fluid on the part of the body that covers the area where the button is pressed. This similarly eliminates the reluctance to have to move.

[0050] In many embodiments of the present invention, signal detector 85 applies a signal across each button resulting in This results in less than 100mW of power dissipation across the button. The current across the button is 50 As a result, the signal across the button is relatively low power. and typically, the buttons 120, 134 or the conductors 124, 136 extending toward the buttons. There is no need to provide an insulating layer covering either 28 or 144. One benefit of this is that the cost of providing this layer is avoided. Another advantage of not having this insulating layer is that it can be added to the face shield. The purpose of face shields is to add an additional visual discontinuity. Face shields are ideally completely transparent. It should be understood that there should be minimal visual discontinuity with the face shield. By doing so, these discontinuities will not affect the user wearing the personal protective system or the personal protective equipment. Minimize the amount of distraction to other parties watching the user wearing the protective system. can be done.

The headband 182 is attached to the rear of the headband 182. When the fan is activated, it draws air through the garment and into the top of the shell 184. The air is discharged through the front bellows 186 and the rear bellows 218, respectively. The air flowing through the front bellows 186 is directed toward the face of the user wearing the system. The air flowing through the rear bellows 218 is discharged before the rear nozzle 220. The rear nozzle 220 is positioned so as to open below the headband 182. The air discharged from the rear nozzle 220 is directed at the neck of the user wearing the system. Discharged to the rear.

[0053] The front nozzle 188 of the helmet 180 is provided with a block 185. 5 is part of a nozzle 188 attached to the headband 182 or In the illustrated embodiment of the invention, the block is an integral component of the helmet 180. 185 is attached to a strap 183 that is part of the headband 182 .

[0054] The front nozzle 188 is also formed with a tab 216. The tab 216 , projecting upward from the leading edge of the nozzle. As shown in FIGS. 10 and 12, block 19 0 protrudes outward from the top surface of the front nozzle 188. The block 190 has a tab 216 In FIG. 10, the base of the tab 216 below the block is cut away. 190 and related components behind the tab. The front surface of the block 190 is formed with three slots 192. A contact 198 is disposed within each of the slots 192. Each contact 198 is made of a conductive, flexible material. The contacts 198 are in the form of thin metal strips. The contacts 198 are curved outward. More specifically, the contacts , which is formed to extend forward of the block 190. Typically, the helmet 180 When the garment is not placed over the helmet, the contact points rest against the rear surface of the tab 216. Although not shown, in some aspects of the present invention, A plate of metal and a series of webs are placed over the block 190. The shaft is configured to retain the contacts 198 within the slots 192 .

[0055] The helmet 180 includes the detector 85 and control device described with respect to the first embodiment of the present invention. Although not shown, in this embodiment of the invention, a conductor similar to conductor 82 is provided. It should be understood that connects each contact 198 to the detector 85.

[0056] The helmet 180 includes a chin bar 224 that extends downward from the front of the headband 182. The chin bar 224 is attached to two posts 226 that extend from either side of the headband 182. A beam 228 extends between the opposing free ends of the posts 226. The chin bar 224 is configured such that the beam 228 is positioned under and above the chin of the user wearing the system 178. The beam 228 is formed so as to be positioned somewhat forward. Two magnets 234 (one shown) are attached to the chin bar 224. Each magnet 234 is positioned adjacent to the outer end of the beam 228 of the jaw bar 224. It is placed.

[0057] The face shield 240 is formed in the shell 238 of the garment 236 (part numbered The face shield 240 is attached to the front (not shown) of the face shield 240 as shown in FIG. The face shield 240 has the same general shape as the previously described shield 110. The face shield 240 is attached to an opening formed in the shell 238 of the face shield 240. A rectangular opening 242 is further formed below the upper end of the field. The opening 242 is shaped to receive the tab 216 integral with the helmet 180. The face shield 240 is secured to the face shield such that two magnets 246 extend inward from the inner surface of the face shield 240. The components of this aspect of the invention are attached to helmet tab 21. 6 is seated within the face shield opening 242 and the face shield 240 bends around the chin bar 224. When lifted, each of the face shield magnets 246 abuts and engages a complementary one of the magnets 234. They are designed to work together to stop

[0058] The aforementioned buttons 120 and 134 are formed on the inner surface of the face shield. Although not shown, the disk 122 and ring 126 form the button 120, and the disk 136 and ring 142 form button 134. Similar to conductor 124, and substantially identical Extending from the disk 122 is a conductor 252 having a shape similar to the conductor 128. Conductors 254 having substantially the same shape extend from the rings 126 and 142. A conductor 256, similar to the conductor 144 and having substantially the same shape, is attached to the disk 13. 6. Conductors 252, 254, and 256 are connected at the following points: 52, 254, and 256 each cover a portion of the face shield that defines the perimeter of the opening 242. The conductors 124, 128, and 144 differ in that they have terminal ends located at the ends of the conductors 124, 128, and 144. As shown in FIG. 11A, the termination of the conductor 252 defines the upper periphery on the right side of the opening 242. The electrical conductor 254 terminates over the area of ​​the face shield that defines the opening 242. The electrical conductors 256 terminate over the area of ​​the face shield that defines the upper portion. It terminates over an area of ​​the face shield that defines the upper peripheral portion of the left side of the opening 242 .

[0059] The components that form this aspect of the system include a helmet tab that opens onto a face shield opening 242. When fully seated within the contact 198, the end of each of the conductors 252, 254, and 256 contacts the contact 198. They are constructed in cooperation with each other so that they line up in a straight line.

[0060] To use the system 178, the helmet 180 is first placed on the user's head. The garment 236 is initially placed over the user's face. The helmet has a tab 216 that is integral with the helmet and is positioned against the face when the garment is turned toward the face. The face shield is positioned so that it rests within the opening 242 in the face shield. and is forced into the space between block 190 and tab 216, resulting in The terminal end of each of the conductors 252, 254, 256 is connected to an associated part of the helmet 180. 12 shows a single conductor, optionally a It shows how the current bodies 254 abut the associated contacts 198 .

[0061] Once the face shield 240 is seated over the tab 216, the garment shell 2 38 shows the helmet 180 (which the system is intended to cover) and the user's anatomy. The face shield 240 is also bent around the helmet. More specifically, the face shield 240 includes a magnet 246 integral with the face shield. is bent to releasably engage a complementary magnet 236 integral with the helmet 180. As a result of this engagement of the magnets 236, 246, the face shield 240 The face shield will have a shape that curves left and right around the head. This curved design increases the field of view outside the face shield for users wearing the system. The curvature of the lower portion of the face shield allows for a more even fit between this area of ​​the face shield and the chin. It is limited by the abutment of the bar 224 with the integral beam 228 .

[0062] The engagement of the conductors 252, 254, and 256 with the contacts 198 causes the buttons 120, 134 It should be understood that electrical connections are established between the detector 85 and the system. This mode functions the same as the first mode of the system. If the user changes the fan speed If control is desired, the user presses the appropriate button 120 or 134. In response to the change in capacitance caused by the actuation, the detector 85 sends an appropriate signal to the controller. The controller 88 then adjusts the motor speed based on which button was pressed. This will be the case.

[0063] A further benefit of this system 178 of the present invention is that it has two functions: The components necessary to provide the physical and electrical connection of the face shield to the The system 178 also reduces the cost of installing the helmet 180. To simplify centering of a face shield (240).

[0064] [II. Second Alternative System] Figure 13 shows three control buttons 120, 134, 262, and 136 mounted on the face shield. 13, the electrical components of the present invention are shown together with the buttons 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 16 34, 262, and 264 are located on both sides of the face shield. Respective contacts integral with the helmet and face shield 240 connect the button to the detector 85a. In this aspect of the invention, the helmet includes a light source 26 in addition to the fan motor 92. 6, a communication unit 268, and a cooling strip 272. The light source 266 is typically , attached to the helmet so as to project a beam of light out of the face shield 240. The communication unit 268 may be an RF transceiver. Alternatively, the communication unit 268 The communication unit may also include an amplifier with a speaker. Typically, the microphone is a helmet-mounted microphone 267. 267 is typically attached to the chin bar. Cooling strip 272 is typically attached to the The protective system consists of components that allow heat to be transferred away from the skin of the wearer. One such strip is disclosed in US Provisional Patent Application No. 62 / 221,266. The contents of this document are incorporated herein by reference. The control device 88a in the same way controls these subassemblies 92, 266, 268 of the system. , 272.

[0065] In this aspect of the invention, each one of buttons 120, 134, 262, and 264 is used to Adjust the operating state of each of the stem motorized subassemblies 92, 266, 268, and 272. Optionally, the controller 88a may be configured to detect that the button 120 has been pressed. When a signal indicating this is received, the speed of the fan motor 92 is increased. When the button 120 is pressed while rotating at high speed, the controller 88a Resets the energization signal applied to the motor 92 to rotate at the minimum speed. Button 134 Based on the pressing of the button 262, the control device 88a controls the light source 266 to be turned on or off. Based on whether it has been pressed, the control unit may then select a transceiver or amplifier that is integral with the communication unit 268. Upon pressing the button 264, the control device turns the cooling strip 2 The voltage level across the active components of the strip 272 is set to set the heat dissipation capability of the strip 272. Set the rule.

[0066] Thus, the buttons of the system of the present invention are used to power the personal protection system other than the fan motor. It should be understood that the present invention may also be used to control electrically active components. In some embodiments, depending on the type of power assembly that is integrated with the helmet, the assembly A single button on the face shield may be sufficient to control the assembly. do.

[0067] [IV. Third Alternative System] FIG. 14 illustrates how a garment-mounted memory 292 is incorporated into a personal protection system 290 of the present invention. 14 shows the electrical components of the system 290. These components are not only compatible with this alternative helmet and garment of the present invention, but also with the previously mentioned It is understood that the system 30, 178 may be attached to helmets and garments. The system 290 includes the aforementioned face seal secured to a garment (not shown). The face shield includes a button 110. A single button 120 is formed on the face shield.

[0068] Also attached to the face shield 110 is a memory 292. The memory 292 stores the system 15 shows the memory 29. 2 shows the type of data stored. Field 302 contains data identifying the minimum fan speed. Field 304 contains data representing the minimum fan speed. The flags area 306 indicates some kind of electrically active component to be included in this particular Includes a flag that is set to indicate whether the helmet is suitable for use with For example, some helmets are equipped with a light assembly that emits ultraviolet light. On the other hand, some garments, such as face shields, do not adequately transmit ultraviolet light. In this type of garment, one of the flags in the area is If the garment contained an ultraviolet light source, when this garment was placed over the helmet, This may be set to indicate that the light source should not be activated when

[0069] The memory 292 also includes a usage history area 308. The usage history area is an area where the memory is integrated. It contains data indicating whether the garment has already been used. The usage history field 308 may be a single bit flag field. The data in the usage history area 308 is stored in each of the memory areas. is set to indicate that it is not in use.

[0070] The memory 292 is a thin film memory label adhesively secured to the inner surface of the face shield 110. In FIG. 14, memory 292 is connected to a contact, optionally to contact 148a. A single conductor 294 is shown connecting the memory. It will be appreciated that it may be necessary to read / write to memory 292 via multiple pins in the system. In these aspects of the invention, to ensure that each memory pin is connected to a contact, To achieve this, the face shield must provide a sufficient number of contact points.

[0071] The helmet of the system 290 includes the aforementioned magnet 64, which acts as an electrical contact, the detector 85, and a control device 88. The system 290 includes only a fan motor 92. The system 290 may include other electrically active components. It should be understood that the helmet of the system 290 also includes a memory interface 312. The memory interface 312 reads data from the memory 292 and The memory interface 312 is configured to write data to the memory 292. , connected to the control device 88. Based on an instruction from the control device 88, the memory reader 8 8 reads the data in the memory and sends this data to the control device. Based on the instruction from the device 88, the memory reader writes the data to the memory 292. Writing of this information usually involves setting a flag in the usage history area 308.

[0072] The system 290 of the present invention also includes an alarm 314. The alarm 314 is typically The alarm is a device capable of emitting a short audible pop. Connected to an alarm for selective activation.

[0073] In the system 290, the memory 292 is connected to a complementary magnet 64 integral with the helmet. The components that support this are magnets 148a and 148b.

[0074] The system 290 of the present invention is similar to other embodiments of the personal protection system of the present invention. The helmet is then placed over the user's head. The garment is worn over the helmet and head. As a result, the respective contacts integral with the helmet and face shield are detected as buttons 120. These contacts establish an electrical connection between the garment and the integral memory 292. and the memory interface 312.

[0075] FIG. 16 shows a flow chart of the process steps performed by the controller 88. These process steps are performed by the system 290 when it is ready for use and the control equipment is This occurs after the device 88 is activated (controller activation steps not shown). Step 322 indicates the initial reading of data in memory 292 by controller 88. Although not explicitly shown, as part of step 322, memory 292 is To determine whether to If no memory is detected, the memory reader will output a message indicating this fact. The control device 88 receives this notification and generates an alarm 314. The alarm 314 is activated when the garment has no memory or has only one memory. The garment is placed on the helmet so that the memory card 92 is securely connected to the memory reader 312. This will result in a notification indicating either that the

[0076] The memory interface reads the data in the memory 292 in step 322. Once the data is read and transmitted to the control device 88, in step 324, The data is analyzed by the control device. The data is evaluated to determine whether it is suitable for use with a helmet. In step 324, the control device determines whether the garment is being identified based on the data in the garment identification area 302. The device 88 determines whether the garment is compatible with the helmet. Based on the data in 08, the control device 88 determines whether the garment has already been used. If this evaluation test is positive, the garment is no longer sterile. and is considered unsuitable for use.

[0077] Step 326 is performed by the controller 88 based on the evaluation of step 324 to determine whether the garment is in use. The reasons why a garment is unsuitable for use include: The nature of the material forming the shell or filter ensures that the fan blows sufficient air into the garment. The garment features do not match the helmet features. Or, data in the usage history area may indicate that the garment has already been used. Regardless of the reason, if, as part of step 326, the garment is If it is determined that the device should not be used with the controller, then in step 330, 88 activates an alarm 314.

[0078] In most cases, the evaluation in step 326 is to ensure that the garment is compatible for use with a helmet. In this case, the controller 88 proceeds with the process and returns to step 33. Execute 2.

[0079] In many aspects of the present invention, the controller 88 continues to perform step 330 after step 330 is performed. 332 because, in these aspects of the invention, the system The garment is designed to only provide a notice that the garment is unsuitable for use, and Alternatively, the system 290 may be configured to If the system is not suitable for use, it may be configured not to allow operation of the system. In these embodiments, the controller 88 does not take any further action after the alarm is activated. No.

[0080] In step 332, the controller 88 and memory interface 312 Write data to garment memory 292 indicating that the garment should be considered for use. In the described embodiment of the invention, in step 332, a memory interface 312 performs this by setting an appropriate flag in the usage history area of ​​memory 292. Execute the process.

[0081] In step 334, the controller 88 determines whether the helmet is to be used with the particular garment. In the described embodiment of the invention, step 334 sets the fan motor Setting the low speed base signal to the speed specified in the minimum fan speed region 304 This process is carried out by: If the garment is made of a relatively porous filtering material, If the data in area 304 consisted of It will be shown that other garments are constructed from relatively low-porosity filtering materials. If the system is to function with this garment, the minimum fan speed is When a garment made of filtration material is attached to a helmet, it is set to a higher velocity than when the garment is attached to a helmet. For this garment, area 304 contains data indicating this fact. There is.

[0082] In some embodiments of the present invention, as part of step 334, the controller 88 Activate 2.

[0083] One benefit of the system 290 of the present invention is that the controller 88 and alarm 314 are The stem is not suitable for use with certain garments worn over the helmet. If so, the method is configured to provide notification of that.

[0084] A further advantage of the system 290 is that it is based on a memory that is integral to the garment, and the controller: The control is to set up the system for use with the garment. This includes setting the minimum speed of the motor. Alternatively, if the light source emits a variable intensity light source, If possible, this control should be based on the radiated light source transmitted through the face shield material properties. This may include setting minimum, maximum, and / or target intensity of the light.

[0085] [V.Alternative contact] The present invention is directed to a face shield in which conductors extending from the button releasably hold the face shield to the helmet. is limited to personal protection systems adapted to extend to one or more fastening features Typically, but not exclusively, the conductors are located below the face shield. the position of the face shield, i.e., the position of the face shield when it is fixed to the helmet. It is sufficient that the contacts extend at least as far as they are aligned with the complementary contacts. The face shield is removably attached to the helmet, resulting in one Alternatively, electrical connections may be established between the buttons and electrical components integral with the helmet. This will ensure that:

[0086] In aspects of the invention where the face shield conductors do not terminate in a fastening feature, a complementary helmet connection may be used. The points do not have to be integral with the helmet securement features that engage with the face shield securement features. It should be understood that the face shield conductor may be adjacent to or not adjacent to the face shield conductor. When terminating at a location spaced apart from the shield securing feature, the helmet contacts are spring-loaded contacts. or pogo pin-like contacts. Each of these contacts is At one time, the conductive pin of the contact is positioned to abut the appropriate face shield conductor. This will happen.

[0087] In all aspects of the present invention, the face shield fixation features do not necessarily have to be part of the face shield guide. It is not necessary for the face shield to also function as a conductive contact for the electrical body. The face shield fastening features that serve as conductive contacts for the face shield conductors are often are believed to constitute a preferred configuration of the invention. For this purpose, they are considered face shield fixation features. For example, a faceplate defining an opening for receiving a complementary helmet fastening feature. The area of ​​the shield is considered a face shield fixation feature. Specifically, the opening in FIG. The area of ​​face shield 240 defining 242 is, for purposes of the present invention, considered to be a face shield fixation area. Please understand that this is considered a symptom.

[0088] The securing features, which are also conductive, are restricted to the openings that define the area of ​​the magnet and face shield. An alternative dual function fastening assembly is a hook-and-loop fastening assembly. In this case, both components of this assembly are Another dual function assembly is a terminal component consisting of two pairs of connectors. One connector has a magnet and a contact. The second connector is attracted to the magnetic field. These connectors have a unique resistance to magnets. The contacts are arranged to contact each other by the etching effect. The flexible locking features include conductive snaps.

[0089] In aspects of the invention where the securing features rely on magnetic attraction, the helmet and garment face shield Both the field and the field do not necessarily have to be fixed features that are both electrically conductive and emit a magnetic field. Therefore, in some aspects of the invention, only one of the helmet or face shield is used. The face shield or helmet has a conductive magnet (which acts as a retainer and conductor). The other end of the met is provided with the aforementioned disk 149 which serves as a complementary fixture and conductive contact. It is available.

[0090] The contacts of the present invention, i.e., the signals are transmitted between the contacts and the buttons and / or The contacts that transmit signals between the memory and the memory are components that transmit signals by the physical transmission of electron flow. For purposes of this invention, helmet contacts and garment contacts are , from the garment-mounted components and the helmet-mounted components It can also be thought of as a component that facilitates the electromagnetic inductive transmission of signals.

[0091] One such assembly is shown in Figure 17, where the main coil 354 is The signal is a constant frequency AC signal that is also part of the helmet. A voltage is applied to the main coil from a voltage source 352. Adjacent to the main coil 354 is a regenerative coil. A detector 360 monitors the characteristics of the signal across the regenerative coil. Detector 360 detects a particular change in the signal across regenerative coil 358. The control unit 88 is configured to output a signal indicating that a change in the value of the voltage Vcc has been detected.

[0092] In this embodiment of the invention, secondary coil 370 is located on face shield 110. The secondary coil 370 is configured such that when the garment is fastened to the helmet, the secondary coil is The main coil 354 and the regenerative coil 358 of the , positioned. Electrical conductors 372 connect both ends of the secondary coil to the button. Although not shown, one electrical conductor 372 may be connected to the disk 122 of the button 120. It should be understood that the second conductor is connected to the ring 126 of the button 120. become.

[0093] When this embodiment of the personal protection system of the present invention is operated, voltage source 352 generates an AC signal is applied across the main coil 354. The proximity of the coils 354, 358, and 370 A signal across coil 354 induces a signal across coil 370. Thus, button 1 This results in a signal traversing the disks 122 and rings 126 forming 20.

[0094] The user can activate the button in the same way as in other aspects of the present invention. Activate button 120 by placing your thumb or finger on the area of ​​the face shield that is The presence of this finger causes the disk 122 and ring 126 that form the button to move across. The capacitance changes, which in turn changes the characteristics of the signal across the coil 370. In response to the detection of this change, the output device 360 ​​sends a signal indicating that the button has been pressed to the control device 8. 8. The controller 88 then selects the appropriate power accessory based on the activation of the button 120. Assembly, in this case, resets the operational state of fan 92.

[0095] In aspects of the invention where the contacts are designed to allow inductive signal transmission, the face seal The memory attached to the card may be an RFID tag. The face shield contact is an antenna integral with the memory attached to the face shield. The helmet contacts are connected to the helmet via a tag antenna for inductive signal exchange. It is.

[0096] [VI. On / Off Control System] As previously discussed with respect to step 334 of FIG. 16, the personal protection system of the present invention Only after the helmet is attached does the controller 88 activate the motor 92 and thus the The fan 94 may be configured to output a signal that causes the fan 94 to operate. , associated with a personal protection system having a fan that is activated before the garment is placed on the helmet One drawback that should be eliminated in this way is that the fan 94 The problem is that the fan 84 makes noise when it serves no useful purpose. A second drawback associated with the motor 92 spinning when not in use is the battery drain caused by the motor. This is the loss of charge in the battery 86.

[0097] Thus, in the process described with respect to FIG. 16, the system draws power from the battery 86. It should be understood that the system operates in two states due to the different currents drawn. When activated, a relatively low current is drawn. Included are a controller 88 and associated input / output components, namely, a detector 85 and memory The only current required is to activate the interface 312. The fan will only operate when the lume is installed over the lume. It should be understood that higher currents will be drawn from the battery 86 when the

[0098] In another aspect of the system of the present invention, the garment is only attached to the helmet when the fan is turned on. A different subassembly is provided to ensure that the motor 92 rotates to operate the motor 94. In one such configuration of the invention, the system may include a controller 88 is configured not to output a command signal that will cause the fan to operate when it is first activated. The controller detects a signal indicating that one of the buttons 120 or 134 has been pressed. The fan is activated only when a signal is received from the receiver 85.

[0099] Figure 18 illustrates the components of an alternative system 390 of the present invention. System 390 includes: A modification of the system of FIG. 4. System 390 is provided so that a single button 120 is provided. Instead of a second button, system 390 is configured such that electrical conductor 392 is The magnet 148b is configured to be disposed on the shield 110. The conductor 392 is configured to be disposed on the magnet 148b. 148c. In these aspects of the invention, detector 85 detects these magnets. Configured to monitor magnets 64b, 64c to detect the presence of an open / closed circuit across them Thus, in these aspects of the invention, detector 85 detects signals traversing magnet 64b. It will output the number.

[0100] When the helmet of the system 390 is first placed on the user's head and activated, detection Only the detector 85 and the control device 88 are active. If an open circuit exists across the magnets 64b and 64c, Therefore, the detector 85 sends a signal to the control device indicating that this is the state of the system 390. Therefore, the control device 88 outputs a control signal to energize the fan motor 92. It will not exist.

[0101] When the garment is fitted to the helmet, the garment's face shield and integral conductor 3 92 closes the connection between magnets 64b and 64c. Detector 85 detects these two The closure of the circuit between magnets 64b and 64c is detected. In response to detecting this change in circuit state, The detector sends a signal to the controller 88 indicating that the system is in this state. Only when this signal is received by the controller 88 will the controller 88 send a signal to the fan motor 92. The actuator outputs a command signal that causes the application of an electrical signal.

[0102] In this embodiment of the invention, removal of the garment from the helmet removes magnets 64b, It should be understood that the circuit between 64c is reopened. Upon detection of this reopening of the circuit, , the detector outputs a signal to the controller 88 informing it that the system is in this state. The controller 88 receives notification that the system 390 has returned to the garment detachment state. In response to this, the application of the energization signal to the fan motor 92 is terminated. A further feature of these configurations of the system is that the garment is removed from the helmet and the fan When use of the motor 92 is no longer required, the fan automatically shuts off.

[0103] Another means of detecting the presence or absence of a garment is shown in Figures 19 and 20. 1 shows a portion of a helmet 32a based on the helmet 32 ​​described above. Instead of having a magnet as a fixture, fixture 4 is conductive and attracted to a magnetic field. The helmet 32 ​​is partially different from the helmet 32 ​​in that it has the following components: 402a, 402b, and 402c. A sensor 404 is disposed adjacent to the fixture 402b. The sensor 404 detects a magnetic field The sensor 404 outputs a signal that changes state based on the presence or absence of the Hall effect sensor. In some aspects of the invention, the sensor 404 is a switch. It should be understood that the open / closed state of the switch is a function of the presence or absence of a magnetic field. , attached to the inside of the shell 36. This is why the sensor 404 is depicted in FIG. This is the reason shown by the lines.

[0104] The signal output by the sensor 404 is output to the control device 88. This signal is Alternatively, the signal may be applied directly to the controller, as shown at 20. 5. Thus, the detector of this aspect of the invention, upon receiving this signal, and outputting a signal to the control device indicating that the garment has been attached to the helmet. , is composed of.

[0105] In these aspects of the invention, the complementary fastening elements integral with the garment are similar to those of the face shield described above. It is a ring magnet 148.

[0106] This aspect of the invention follows the same basic steps as other aspects of the invention when prepared for use. According to this aspect of the invention, the helmet is prepared for use using the following steps: Therefore, only the detector 85 and the control device 88 are activated. a magnet 148a integral with the garment face shield 110 for releasably attaching to the 148b, 148c are respectively attached to the fixing members 402a, 402b, 402c of the helmet 32a. 2c. The magnet 148a is positioned adjacent to the sensor 404. The generated magnetic field flows around the sensor. The sensor 404 then detects the presence of this magnetic field. If the sensor 404 is a switch, it will output a signal indicating the presence of a magnetic field. Depending on this signal output by the sensor, the switch is closed or opened. The controller 88 sends a signal to the motor 92 to operate the motor 92 and rotate the fan 94. The application of the energization signal is started.

[0107] Alternatively, a sensor that outputs a signal indicating whether the garment is worn on the helmet. This switch 404a may be the switch 404a in FIG. Physical displacement when the garment is donned or removed from the helmet In this aspect of the invention, the sensor 404a has a spring-loaded pin. The switch may be a switch that activates the garment when it is attached to the face shield. The garment is attached to the helmet in a position that displaces the pin when the garment is kicked. Typically, the switch is positioned so that the garment is attached to the face when worn over the helmet. Either the shield or a component attached to the face shield abuts against the pin, and the pin This displacement of the pin activates the switch. The state of the controller 88 is changed. The state of the switch indicates whether the garment is worn over the helmet. Based on this switch state information, In this case, the control device adjusts the application of the energization signal to the fan motor 92.

[0108] Thus, in the above-described embodiment of the invention, the portion of the garment that depresses the switch on sensor 404a It is understood that the sensor acts as a garment mark to indicate the presence of a garment adjacent to the sensor. In FIG. 21A, this is illustrated by area 110a of face shield 110. is shown formally.

[0109] In some embodiments of the personal protection of the present invention, the garment may be attached to a helmet or not. Based on the information indicating whether other electrically powered assemblies integral with the personal protective system are operating, the control device The control unit therefore determines whether the appropriate garment is fitted to the helmet. Depending on whether the optical assembly 266, the communication unit 268, or the cooling strip The operation of one or more of the taps 272 may be inhibited.

[0112] The particular features of the invention may vary from those described herein.

[0113] For example, the control buttons attached to the face shield of this system are For example, in some aspects of the invention, the buttons and the helmet may be different. The integral complementary component reduces the button resistance that results from placing a thumb or finger on the button. In aspects of the invention where the button is sensitive to changes in resistance, Preferably, the conductive material forming the buttons is attached to the exterior surface of the face shield. In other aspects, for other reasons, the conductive features of the button as well as the face shield conductors themselves may be The body may also be placed on the exterior of the face shield.

[0114] Additionally, in some aspects of the present invention, the button may include a moving component. Typically, this type of button has at least one moving component that activates the button. The button is designed to be physically displaced relative to the other components of the button to allow for a One such button is a membrane button or switch. The flexibility of the membrane allows the circuit of the associated button to be closed. You will be chained.

[0115] In all aspects of the present invention, the buttons do not necessarily have to be adjacent to one or both sides of the face shield. These buttons do not need to be located adjacent to the top and / or bottom of the face shield. It may be placed close to the

[0116] Regardless of their form, the buttons of the present invention are intended to be actuated by the depression of a gloved finger. It should be understood that in a medical or surgical environment, the system of the present invention This is because clothed users typically wear gloves on their hands.

[0117] The button of the present invention can also be attached to a garment that includes one or more peel-off lenses. The peel-away lens may be adhesively secured to the exposed outer surface of the face shield. This lens is covered by a material that blocks the view of the face shield. This lens is removed when the garment is worn. , at least for a short period of time, the face shield is not obstructed by the material covering it. This removable shield allows the user to have full view of the buttons. will be exposed.

[0118] Furthermore, in some embodiments of the present invention, when the garment is worn over a helmet, and positioning the components such that electrical contacts integral with the helmet contact complementary contacts integral with the button. In these aspects of the invention, the electrical contacts of the face shield are preferably positioned The benefit of this aspect of the invention is that the face shield is spaced from the button. The advantage of this is that there is no need to provide the face shield with conductors extending to the cold contacts.

[0119] Alternative units that can be attached to personal protection systems include video and / or audio recorders. The button can activate this system.

[0120] Also, in some aspects of the invention, the face shield may include complementary helmet securing features. The locking feature may not be included to engage with the locking feature.

[0121] In some aspects of the invention, the buttons and / or face shield conductors extending to the buttons It may be desirable to place an insulating layer over the

[0122] It is understood that the sensor that outputs a signal based on the presence or absence of a garment may take other forms. It should be understood that Figure 21B shows an alternative sensor 404b that is an optical recognition sensor. The sensor (shown in FIG. 21B as a bar 410 on a portion of the face shield 110) 410 a face shield or a visually perceptible mark attached to the face shield This mark 410 can be a bar code or a colored tile. Based on the presence or absence of the appropriate markings, the sensor determines whether the face shield is A signal is generated to indicate whether the lumet is attached or not. The control device 88 selectively activates one or more of the electrically powered assemblies integral with the personal protection system. This will result in the following:

[0123] As previously described in some embodiments of the present invention, the NOVRAM or RFID tag Such a memory device may be attached to the face shield. The memory interface that reads data from the memory is attached to the face shield. It functions as a sensor to detect the presence or absence of a memory. Unless the memory interface receives data as a result of a write request issued by The control unit is designed to prevent personal protection systems from In response to a write request, the memory interface reads data from the memory. When the face shield is received, the control unit determines that the face shield is attached to the helmet. Only when the system is in this state will the helmet be able to operate the powered components of the system. This will activate one or more of the components.

[0124] The personal protection system of the present invention also generally provides a means for protecting a medical practitioner from a medical or surgical procedure. Although intended to provide a barrier between the patient and the device, its use is not limited to such Personal protection should provide a barrier between the user and the environment. It is within the scope of the present invention that the system of the present invention may be used in other endeavors. One alternative approach that is recommended is to identify hazards in the user and the environment in which they work. Examples of use cases include those where it is desirable to provide a barrier between the device and the material.

[0125] Additionally, the form of the conductive material forming the buttons and conductive traces on the face shield is conductive. In some aspects of the invention, these conductive structures are not limited to tracks. The elements may be formed from conductive ink applied to the face shield. The conductive components may be formed from a conductive layer applied to the face shield. Once applied to the face shield, these conductive layers are then bonded together to form the individual conductive components. Therefore, the film is selectively etched.

[0126] Furthermore, a unique feature of the personal protection system of the present invention is that the key aspects of the system described above Personal protection excluding the complete helmet and head-covering garment illustrated in For example, the minimum personal protection system of the present invention may be incorporated into a fan and a helmet that does not have a top-mounted shell to which a motor is attached. The garment should consist only of a face shield that is attached to this helmet. In this aspect of the system, the assembly described above includes a face shield attached to a headband. Prohibits the use of a motorized assembly attached to the headband, depending on whether it is attached or not.
