Medical Devices and COVID-19

有关使用Laerdal吸入单元（LSU）和Laerdal紧凑吸入单元4（LCSU 4）时患有细菌或病毒感染患者的信息。有关莱德尔动力吸力装置排气的信息。

The Laerdal Suction Unit (LSU) and Laerdal Compact Suction Unit 4 (LCSU 4) are suitable for suctioning patients with a proven viral or bacterial infection because patient fluid is contained in a canister.

The LSU and LCSU 4 canisters have mechanisms that that are designed to safely contain patient fluids. When the LSU or LCSU 4 are used as intended no fluids will enter the suction unit. The LSU and LCSU 4 will stop suctioning if the canister is full or the suction unit tips over. Aerosol filters in LSU and LCSU 4 prevent fluids or aerosols from entering into the suction unit.

Exhaust from the suction units is not an aerosol. The exhaust is not expected to transmit bacteria or virus, such as COVID-19 which are transmitted in aerosols. If the suction unit is contaminated with fluids the exhaust can also be contaminated. If fluids come into the suction unit, the unit should be removed from use and treated as contaminated equipment in accordance with local protocols.

All suctioning must be carried out using a suction catheter. The suction catheter is not provided by Laerdal.

Please note: COVID-19 is reported to be between 0.06 and 0.14 um in diameter. According to current knowledge, COVID-19 is transmitted via respiratory droplets, aerosols and by surface contact[1]. The filters used in LSU and in N95 masks have similar filtering efficiency. N95 masks, which are commonly recommended for protection against viruses such as COVID-19 shall block minimum 95% of all particles.

继Covid-19爆发世界卫生组织（世卫组织）发布了以下关于环境清洁的信息：

Environmental cleaning in healthcare facilities or homes housing patients with suspected or confirmed 2019-nCoV infection should use disinfectants that are active against enveloped viruses, such as 2019-nCoV and other coronaviruses. There are many disinfectants, including commonly used hospital disinfectants, that are active against enveloped viruses. Currently WHO recommendations include the use of:

70％乙醇在用途之间消毒可重复使用的专用设备（例如，温度计）。
次氯酸钠在0.5%(武器装备valent 5000ppm) for disinfection of frequently touched surfaces in homes or healthcare facilities

Use a cloth or sponge that is dampened with a mild detergent (hand dishwashing liquid or similar) to clean the external surfaces of the LSU.

使用与材料图表中列出的材料兼容的洗涤剂，并遵循洗涤剂制造商的说明。

Use a cloth or sponge dampened with water and wipe the surfaces again.

使用清洁布或纸巾干燥表面。

In light of the current WHO recommendations Laerdal has reviewed its recommendations for cleaning. Laerdal has not tested the LSU using 70% Ethyl alcohol or Sodium hypochlorite at 0.5%.

Specific parts for LSU with Serres Canister

特定部件属于LSU W / Serres吸袋

For canister parts refer to DFU (part no. 20-15830), p.11-12

面罩和口袋面罩有过滤器，Technostat T-150（+）/ 15。此过滤器仅用于单次患者使用。该过滤器旨在保护救援人员免受细菌和病毒的保护，病毒和细菌效果≥99％。

Bemis Canister (88 30 00) and patient tube (78 04 12)

For the LSU Bemis (catalog number 78 00 20 01) the single-use canister (catalog number 883000 ) contains a filter in the lid. This filter has been tested for its viral and bacterial efficacy and is found to have 99.9% viral and bacterial filtration efficiency.

LSU BEMIS（78 00 20 01）配有高效滤波器套件（78 04 13 34）

The LSU Bemis can be used with the high-efficiency filter kit (catalog number 78041334 ). The bidirectional hydrophobic Intervene 7 Filter from Pall Medical* meets HEPA standards** with a filter efficiency of 99.97% down to 0.3µm and may be used together with ***Laerdal Suction Unit to reduce the risk of contamination from the exhaust air of the suction pump.

**HEPA (High-Efficiency Particulate Air) claims for the Intervene 7 filter are documented by Pall Medical.
***莱德拉尔抽吸装置，用户指南，第3.2.3段测试

78 12 00 Aerosol Filter for LSU Reusable Canister (left) and LSU (78 00 00 xx) with aerosol filter fitted (right)

The reusable LSU (catalog numbers 78 00 00 xx) must be used with the aerosol filter (catalog number 781200 ). The Aerosol Filter protects the LSU by preventing aerosols from entering the pump unit. It is not intended for microbiological or for particle filtration. The Aerosol Filter is not designed for decontamination. It is recommended that the Aerosol Filter be replaced after each use or at least once every shift.

All Serres suction bags are equipped with a hydrophobic filter. The hydrophobic filter acts as a combined bacterial filter and overflow protection. The filter closes suction automatically when it comes in contact with fluids preventing liquid and particles dissolved in the liquid entering the vacuum source.

The bacteria filtration efficiency (BFE) is on average 99,97%. (Staphylococcus aureus, ASTM F2101, Nelson Laboratories, LLC)

>99,9% of particles size 0,4μm or greater are filtered from the air. (independently tested by VTT Finland, data available on request)

Serres还提供病毒过滤器（REF 57702）。但是，在使用Serres罐时，不可能将该过滤器连接到劳埃尔达抽吸单元。

LCSU 4 300 mL罐（目录号886100）具有内部过滤器，该内部过滤器是为了防止液体进入泵单元，如果倾斜或罐装。该过滤器尚未测试其病毒或细菌疗效。

LCSU-4 800 ml canister, patient tube and vacuum tube

来自BEMIS的LCSU 4 800ml罐（目录号886102）在盖子内部具有机械阀，该机械阀在罐满时防止液体进入泵单元。罐盖还包含Aerostat®细菌过滤器，以防止污染。

LCSU-4 800毫升的高效过滤器套件

The LCSU 4 800 ml has an optional high-efficiency filter kit (catalog number 886116 ). The filter is HEPA rated with an efficiency of 99.97% down to a particle size of 0.3 μm. The use of the kit will reduce the airflow and battery run time.

衣物硅氧烷复苏器（LSR）和袋子II不提供过滤器。

We recommend that you use an HMEF filter between the patient valve and the mask, the ET or Supraglottic tube. This is a standard filter that is widely available. A filter with a 22F/15M connector will fit both the Laerdal Silicone Resuscitator and The BAG II. Currently, Laerdal does not supply this type of filter.
