Introduction

Oxygen supplementation can be used as part of the management of patients with chronic, acute to chronic, and acute respiratory disorders. The supplemental oxygen content depends on Based on the needs of each patient in different conditions. The health management team usually pre-determines the endpoint of treatment, for example, the target value of oxygen saturation. The amount of supplemental oxygen can be controlled by the flow rate. The purpose of long-term oxygen therapy is to keep the oxygen saturation of patients who need supplemental oxygen greater than 90%. The flow should correspond to rest, exercise and sleep Sleep is adjusted separately to meet the needs of individual patients under these different conditions. Ideally, the oxygen flow is adjusted to the patient's resting The state can maintain the pulse oximeter indicating SpO2 >90%. Supplemental oxygen can be provided by different oxygen sources. medical gas pipeline system, oxygen concentrator, oxygen cylinder and liquid oxygen. Headquarters The specific requirements for the basic safety and basic performance of the oxygen concentrator are sub-specified. Oxygen concentrator produces oxygen-enriched air from ambient air for delivery For patients who need oxygen therapy. The most common oxygen concentrator uses a molecular sieve bed to screen and filter oxygen from ambient air to produce oxygen. The gas concentration is generally 82% to 96%. The main component of this type of oxygen concentrator is molecular sieve, which can adsorb nitrogen from the air Gas, to produce gas, typically a mixture of 95% oxygen and 5% other gases. The periodic adsorption and discharge of nitrogen is called pressure swing adsorption. Attached process. Medical electrical equipment-Part 2-69: Oxygen concentrator Special requirements for basic safety and basic performance 201.1 Scope, purpose and related standards In addition to the following, Chapter 1 of GB 9706.1-2020 is applicable. 201.1.1 Scope The 1.1 of GB 9706.1-2020 is replaced with. This part specifies the special requirements for the basic safety and basic performance of oxygen concentrators and their accessories. The concentration of gas oxygen delivered to a single patient. This type of oxygen concentrator is usually used in home care environments, including in any private transportation, public transportation It can be operated by a single patient when transferred to an environment including a commercial aircraft.

Note 1: This type of oxygen concentrator can also be used in professional health care institutions. This section applies to oxygen concentrators that can be operated during transfer and those that can be operated during non-transfer. This section applies to integration with or with other medical An oxygen concentrator used with medical equipment, ME equipment or ME systems. Example 1: Oxygen concentrator with oxygen saving device [10] or humidifier [3]. Example 2: Oxygen concentrator used with a separate flow meter. Example 3: An oxygen concentrator used in an anesthesia system [6] used in an area with limited power and logistics supply of anesthetic gas. Example 4: Oxygen concentrator with liquid oxygen tank or gas cylinder filling system. This section also applies to those who are expected to be connected to the oxygen concentrator, and its characteristics affect the basic safety and basic performance of the oxygen concentrator Attachments. This section does not specify the requirements for oxygen concentrators used in medical gas piping systems, see YY 1468 for their requirements. If a chapter or article only applies to ME equipment, or only to ME systems, the title and content of the chapter or article will explain. Otherwise, this chapter or this article applies to related ME equipment and ME systems at the same time. In addition to 7.2.13 and 8.4.1 of the general standard, the expected physiological effects of the ME equipment or ME system within the scope of this part are caused by There are no specific requirements for hazards in this section.

The purpose of this section is to specify the basic safety and basic performance specific requirements for oxygen concentrators [see definition in.201.3.203] and its accessories. Note. The accessories are included in the standard range, because it is necessary to ensure that the oxygen concentrator and accessories are fully safe when used together. The attachment may be for the oxygen concentrator Basic safety and basic performance have an important impact. 201.1.3 Parallel standards 1.3 of GB 9706.1-2020 applies, adding. This section refers to Chapter 2 of the General Standards and applicable parallel standards listed in.201.2 of this section.

1 Scope

YY 9706.269 is the mandatory Chinese standard for oxygen concentrators, the devices that produce oxygen from room air for patients on long-term oxygen therapy at home. It sets the particular requirements for basic safety and essential performance on top of the general medical electrical safety standard, covering the oxygen concentration actually delivered and how it is monitored, the flow accuracy, the alarms that warn when concentration falls, the fire risk inherent in an oxygen-enriched atmosphere, and the behaviour on power failure. Concentrators are sold in China both as prescribed medical devices and, less controllably, direct to consumers, and demand rose sharply during the pandemic years. Being a YY standard without the /T suffix, compliance is compulsory. It took effect in May 2023.
