General device description: The pre-amendment (original) Laerdal™ Suction Unit (LSU) was developed in 1969. It consisted of functional components equivalent to most other portable electrically-operated suction devices on the market, i.e., operational controls and circuits, suction pump with motor, and a disposable or reusable collection canister with tubing. However, the LSU was intended for portable use, in emergency application environments, where conventional AC house current was typically unavailable. Therefore, the LSU was powered by rechargeable batteries, all above components were kept to minimum size and weight, and the entire apparatus housed in a rugged carrying case with built-in handle.
Configuration: The suction pump component assembly is connected to the collection canister component by means of collapse-resistant suction tubing. A longer piece of (patient) suction tubing is also connected to the canister. The latter is the means of conveyance of secretions from the patient to the collection canister. All cited predicate devices are constructed of components and assemblies arranged in the same fashion.
1
Operating and scientific principals: When the assembled unit is switched "On", the circuits direct electrical current from the battery to the pump/motor assembly. The pump operates to evacuate air from the collection canister. The resulting subatmospheric condition causes air to flow upward from the distal end of the patient suction tubing and into the canister. Thus, when called upon to do so, secretions can be carried through the tubing (suctioned from the patient) and then deposited into the canister. Small features e.g., increased diameter of suction tubing and addition of a shoulder-carrying strap, and others, were taken into LSU production in efforts toward continuous improvement.
Predicate device improvements: In 1984, the Laerdal™ Suction Unit was somewhat redesigned to meet new user needs for extended operating time, larger collection canister and the provision of a suction regulator with gauge. These 510(k) K840110 versions remain in common use.
The 1995 device (LPSU) was a design with fewer parts to assure more rational manufacturing, and an equally effective suction pump at a lower cost. The LPSU design incorporates user convenience features, i.e., direct access controls and tubing storage, and meets user needs for specified performance relating to airflow, vacuum and battery operation time. These 510(k) K950698 versions remain in common use
Subiect device description: The 1999 device (LSU4000) is a new more modern, unique solid design witch added benefits of more user-friendly controls, a batery level indicator, and a built in AC adapter. LSU performance is virtually the same as for its predicate designs and configurations.
Components: The subject LSU consists of a high-speed piston pump powered directly by an electric motor, an internal 12 V sealed lead-acid rechargeable battery, an electronic circuit board with controls and signalling light-emitting diodes. All components are assembled into a custom plastic cabinet. The 12 V battery and 8,4 V motor make it possible to both operate and charge the unit from any 12 - 28 VDC, 4 Amp source. Charging may also take place utilizing the internal 110-230 VAC power adapter.
Collection canister: The LSU utilizes a single patient use, standard disposable suction canister that is injection molded in a transparent plastic material. The canister sidewall has graduation marks, which indicate volume of contents. The lid has properly marked connection ports, internal bacterial filter and overflow protection mechanism.
Instruction for use: Directions for use are virtually the same as for the predicate LPSU. Users of a suction device should also be well trained in the safe and proper use of medical suction equipment.
Indications for use: Indications for use are identical for the predicate products cited, and also more than 20 others sold in the US market, i.e., to remove obstructing secretions, blood or vomits from a patient's airway, to keep air passages to lungs open to allow ventilation.

Preparation for use: The LSU4000 will be provided assembled and ready for the first use. Operator/device self-orientation, and unit charging as directed, are the prerequisites to use.
To use: The rescuer/user extends the suction tubing, switches the unit on and sets the desired suction level of 80,120, 200, 350, or 500+. The patient end of the tubing, with or without an optional suction tip, is ready to suction blood or vomits from a patient's mouth and airway.
Suctioning: The high velocity of the airflow will suction liquid and particles through the tubing and into the canister. Lower suction and airflow is sometimes desired to reduce the potential for tissue damage on children or when performing tracheal suctioning. This can be obtained by adjusting the vacuum regulator appropriately.
Preparation for re-use: After every use the LSU4000 exterior surfaces must be wiped clean, the unit refitted with a new disposable canister and suction tubing, and be connected to a 12 - 28 VDC or 100 -230 VAC /50-400 Hz power source for recharging of the internal battery. This is the same procedure as for predicate devices.
Technological comparison with predicate Laerdal devices:
Similarities:
Materials are selected to provide a durable unit with equivalent performance to other Laerdal devices. All active pump parts are injection molded. The unit can be operated from its internal rechargeable battery, or from almost any 12-28V DC power source. The 12-28V DC also provides power to facilitate charging of the internal battery.
Differences:
The LSU pump is a high-speed piston pump. Predicates are moderate-speed piston, highspeed piston or high-speed diaphragm types. LSU operates from a sealed lead-acid battery. One predicate utilizes a nickel-cadmium type battery. The LSU4000 can be operated or charged directly from 110 / 230V AC power. All predicates need an external AC power supply. The LSU4000 is a 5-speed pump. Two predicate is a single-speed pumps, another is a two-speed pump. The LSU 4000 apparatus utilizes a combination cabinet/carrying case of size and design different from its predicates. The LSU 4000 has electronics to control flow, vacuum, battery charging and self-test functions. Predicates have mechanical vacuum regulators. For the LSU, the actual vacuum level will be displayed using an LED bar-graph display. Predicates use analogue mechanical vacuum gauges. The battery of LSU can easily be replaced w/o the use of tools. For the predicate devices, tools are required.
