FI117043B - Respirator with sensor - Google Patents

Description

BACKGROUND OF THE INVENTION The invention relates generally to the use of an electronic sensor in a personal and medical device.

A personal protective device is herein a patented protective device intended for use by a single user 10 which is intended to protect the user from environmental hazards. A typical personal protective device is a gas mask or general protective device to protect the user against gaseous, particulate contaminants in the ambient air. Figure 1 shows the technique t; a respirator 100 having a face part 101 and a fan part 102, already having a chute 103. The fan part 102 has a fan 104 which sucks through filters 105 attached to the lint and blows your filtration through the air hose 103 to the face part 101. exhalation valve 106.

20 Respiratory protection and other personal protective equipment should be maintained at regular intervals and strictly limited in their use in order to ensure safe use. For example, s uses only a certain number of hours. A particular protective device can also be unambiguously 9 and in many cases advantageous to the use history of the protective device \ X \ 25 in planning its future use. In addition, you should ensure that: V: the user in the operating environment is equipped with a protective device, j '; in that particular environment.

Of course, for identification purposes, the protective device can be marked * · 30 la. Protective equipment and its parts may also be marked with a drive. . and / or other chemical exposure and aging that affect use. It is a further object of the invention to provide for easy modification of identification information and use history.

The objects of the invention are achieved by integration into a personal memory.

The respirator according to the invention is characterized in that it has a memory for storing information about the respirator.

Satellite memory is an electronic device known per se, which means a better entity as an electronically readable identifier. A single memory is only a certain amount of non-volatile memory with a connector for connecting a read and write head, which can be read with 15 read and write devices, and can be modified by a more versatile memory. It is possible to modify the contents of the memory circuit without the need for a reading and positioning head that links to the circuit or the connection to it.Memory memories have been used to track, among other things, industrial products aiming at 20 millimeters. Another typical escapade is the attachment of an accessory memory to a machine tool blade (typically, a unique identifier and information for the tool can be stored in the v: 'accessory memory • ψ

This unpredictable advantage is related to the specific properties of respirators or general personal protective equipment and requires respiratory protection consisting of parts that may be combined to allow only certain types of parts to be used, to ensure that the respirator is only approved for use by others. In addition, in laboratories, industrial plant 10, in environments known in advance to have a particular respirator in a particular space, may be provided with an entrance sensor array that only allows a user whose readings from the respiratory tract to indicate that he is defective.

The invention will now be described in more detail with reference to the preferred embodiments and the accompanying drawings, in which Fig. 1 shows a known respirator, Fig. 2 shows a respirator according to the invention, Fig. 3 shows another respirator according to the invention.

♦ · · 999 m 9: 25 Figure 4 illustrates the preferred use of the respirator shown in Figure 3.

Above, in connection with the description of the prior art, reference is made to Figure 1, and in the description of the invention and its preferred embodiments, reference is made to 9 to 9. The same reference numeral 30 is used in the figures for similar parts. . Figure 2 illustrates a respirator 200 consisting of a plastic insert as such, whereby the accessory memory may be placed in a mold. Naturally, the boot memory, which is completely surrounded by the plastic material, can be read and the hedgehogs can only be 5 in the case of a remote memory equipped with a boot memory. This memory is very well protected from mechanical and chemical stress vs the invention does not limit whether it is seamlessly visible or hidden inside the housing part or part of the wall.

10 If the respirator shown in Figure 2 is considered to have a separate <at each of the locations marked in the figure, a cooking mode is used which uses a non-volatile memory to ensure that only legitimate parts are connected. Prior to using the combination, spoofs may, with a device that can be programmed to indicate whether all 15 memories have a tag that identifies a part of the approved one with other parts in the same respirator. On the other hand, the parts shown may include, in addition to or instead of the random access memory, a car device which reads the other parts connected to the same combination s to indicate to the user whether the parts are compatible with the read contents of the random memory.

Fig. 3 illustrates a respirator 300 having only one flap memory, while flare flap 301 is located in a flap 1 where filters 303 are directly connected to the face without a separate air tube. The memory 301 (as well as one or more images 205) may store individual respirator information about the manufacturer, the manufacturing site and the date of manufacture, as well as: V: quality inspections, information on maintenance and repairs performed, »1 30 suitable respirator and / or other respirator and its k. . relevant information. Reads and / or writes data to the boot memory <5 301 and reads the type of environment in which the boot protection is intended. The reading device 402 does not allow the opening of the electric lock 403; readings indicate breathing on the user's head! of the type or its most recent service has elapsed more than k 5 days or that any other condition for allowing the door to open does not function in some way as a key to the access control system associated with type j respiratory protection; previous usage history.

The invention as such does not limit how immaculately placed the breaths, how the reading device is positioned near the door of an object of importance for access control. The arrangement of Fig. 4 achieves serviceability because the reader reads the access memory when breathing in a valid operating position, and the user does not necessarily even need the access path in the ventilator used and the door 401 is slid into position.

The above embodiments of the invention are, of course, only ancillary and have no limiting effect on the invention.
