ASPIRATORS, THORACIC

Purpose

Uterine aspirators provide constant high-vacuum suction (at least 400 mm Hg) and high flow through a fine

curet to evacuate fluid and tissue from the uterus. Uterine aspiration is used primarily for dilation and evacuation

(D & E) therapy for terminating early pregnancies (up to 12 weeks), treatment of incomplete spontaneous

abortions, and removal of retained afterbirth.

Aspiration is also used in diagnostic dilation and curettage (D & C) procedures in hospitals and in endometrial biopsy procedures in physician offices to remove the outermost layers of the endometrium (uterus lining) so that

further microscopic examination can be performed.

Principles of operation

A basic uterine aspirator consists of a vacuum pump, a vacuum regulator and gauge, vacuum curets, a curet

handle, two collection bottles, and an optional bacterial filter. Plastic tubing connects these components,

completing an open-ended system that continuously draws tissue and fluid from the patient’s uterus into the

collection bottles. The gauge allows the user to set a safe limit for suctioning, to assess the performance of the

vacuum pump, and to detect leaks or blockages. Units are either portable or mounted on a stand or cart for

mobility.

Vacuum pumps

A single or double vacuum pump creates suction within the system.

Double-pump systems operate in synchrony, with both pumps

contributing to the suctioning capacity and increasing the airflow. The

three types of pumps used in uterine aspirators are rotary vane,

diaphragm, and cylinder piston.

In a rotary-vane pump, a rotor is mounted off-center in relation to

Figure 1. Rotary-vane pump

the inside diameter of the pump housing (see Figure 1).

As the rotor turns, sliding vanes that fit into notches in

the rotor follow the contour of the housing. Air that is

trapped between a set of vanes is compressed and

expelled through the pressure outlet. As rotation

continues, the space between the vanes expands, and the

pressure of the air trapped between the vanes drops,

creating suction. Several rotary-vane models use graphite

vanes because of the friction between the vanes and the

chamber wall and the need to achieve airtight contact.

In a diaphragm pump, a mechanical drive flexes a

rubber diaphragm back and forth in a chamber,

alternately increasing and decreasing the chamber

volume (see Figure 2). As the chamber volume decreases,

air is compressed and directed out through the one-way exhaust valve; as it increases, a vacuum draws air into

the one-way intake valve.

Uterine aspirators that use cylinder pistons to create suction operate similarly to diaphragm pumps; however,

the pistons slide in a reciprocating motion within the pump cylinder to alternately increase and decrease chamber

volume and pressure. One-way valves respond to pressure differences to draw air from the patient end of the

tubing.

Vacuum curets

Uterine aspirators apply suction to the patient’s uterus through vacuum curets that are available in various

types, sizes, and tip designs. Rigid curets are made of plastic or metal (stainless steel or chrome plated) and are

either curved or straight (a curved shaft reduces the risk of perforating the uterus). Semirigid and flexible curets

are made of nylon or plastic. Plastic curets are often transparent to allow maximum visibility during suctioning. A

stylet can be placed inside a flexible curet to give it rigidity during insertion. Many manufacturers can also

custom-design curets for specialized procedures.Most curets are 15 to 31 cm (6 to 12 in) in length and 2 to 16 mm (0.078 to 0.63 in) in outer diameter. In some

uterine aspirators, the outer diameter of the curet varies within a specified range based on whether the curet is

rigid, semirigid, or flexible. The type of curet used

depends on the procedure, the size of the patient’s

cervix, and the type of material being aspirated.

Most curets have a single opening located at the top

or on the side of the shaft to allow the passage of

aspirate from the patient; some curets have a dual-

sided opening, while others have two separate

openings. Regardless of the type and size, all curets

have a tapered base that fits into a dedicatedhandle/hose assembly, which swivels to allow free

movement within the uterus during aspiration. In

addition to being controlled by the regulator, suction

can also be controlled through the use of a footswitch,

use of an on/off switch in the handle/hose assembly, or

placement of a finger over holes in the shaft of the curet

to increase suctioning power.

Collection bottles

Aspirate from the curet passes through the tubing and into the collection bottle. Most manufacturers have

moved away from use of reusable glass collection containers toward use of plastic disposable units, which save

cleaning time and prevent cross-contamination among patients and hospital personnel. If the aspirator utilizes a

glass bottle, it must be emptied, cleaned, and sterilized after use on each patient.

When large volumes of tissue and fluid are removed from the uterus, aspirate can collect within the bottles

quickly. As a result, most uterine aspirators use two collection bottles connected in series. The bottle closest to the

curet collects aspirate primarily for later microscopic examination or disposal. Gauze sacks can be attached within

this bottle to collect the specimens. The second bottle, called a “trap,” collects the overflow from the first bottle,

allowing the operator to postpone emptying it in response to the rising level of aspirate.

Most uterine aspirators have an overflow-protection assembly in

the cap of the second bottle to prevent large amounts of fluid from

overflowing into the pump and valves. Some units feature a third

bottle to collect overflow. Most uterine aspirators use a float

mechanism as overflow protection. As aspirate collects in the

second bottle, a ball or other mechanical device floats to the top,

covering the opening leading to the suction source and cutting off

suction, thereby alerting the user that the collection bottle is full.

This overflow mechanism cannot be totally relied upon to prevent

pump contamination; often, some fluid passes through the tubing

to the pump before the float blocks the opening. As a result, most

aspirators also include a disposable in-line hydrophobic filter

between the trap bottle and the pump. This filter prevents fluid or

aerosol contaminants from flowing back into the vacuum pump; it

can be reused several times, provided that no overflow has

occurred. Although most units have these overflow-protection

features, the user should check the collection bottles frequently and

not allow them to fill above the caution line.In some systems, a special filter/specimen container fitted

between the curet handle and the hose leading to the collection

bottle is used in place of a gauze sack to collect uterine samples for

microscopic examination. This container has a filter to trap solid aspirate (tissue fragments) yet allows fluid to

pass through the tubing and into the collection bottle. When an adequate sample has been obtained, the container

is removed and capped.

Reported problems

Perforation, hemorrhage, or infection of the uterus from aspiration can result in unanticipated surgery.

Perforations of the uterine wall—such as those caused by overinserting a curet or applying too much vacuum to

increase the airflow—are rare when trained personnel aspirate the patient and when an appropriately sized curet

is used. In addition, curets can rupture an artery, a vein, or a capillary, causing hemorrhaging. Unsterilized curets

can introduce pathogens into the uterus, thereby producing infections that complicate the recovery process.

Bacterial endometritis, a common inflammatory condition, can occur following aspiration. Failed abortion can

result if improper aspiration techniques are used or if the curet is too small.

Factors affecting pump operation can also alter aspiration. Aspirate that overflows beyond the second bottle

and filter can enter the pump and clog the valves; a clogged pump can jam and be difficult to restart. A pump

containing aspirated fluid can also be a source of contamination.

Purchase considerations

ECRI Institute recommendations

Included in the accompanying comparison chart are ECRI Institute’s recommendations for minimum

performance requirements for uterine aspirators. Units should have an adjustable vacuum range with at least a

400 mm Hg maximum vacuum level and a flow rate higher than 30 L/min at maximum vacuum, as well as some

type of vacuum-level regulator. Vacuum level should be displayed in mm Hg. Collection canisters should hold at

least 1.5 L of liquid and have overflow protection or another anticontamination mechanism. Because uterine

aspirators are used in potentially wet environments, they should be impervious to fluid spills. Manufacturers

should specify methods to clean and disinfect units.

Other considerations

The aspirator should be easy and intuitive to turn on, adjust, and operate. Emptying and exchanging reusable

canisters should be uncomplicated and without significant risk of instrument or operator contamination.

Discarding disposable canisters and their contents should be easy, with minimal risk of spills or contamination.

Some manufacturers offer disposable collection containers. The cost of disposables should be weighed againstthe cost, time, and infection risks associated with the disinfection of reusables. Most units with disposable

containers can accept alternative manufacturers’ containers. These standard containers may be more convenient

to order and offer the user a choice of suppliers. However, installed filters supplied with the canisters will differ;

some may severely limit airflow rates.

Some manufacturers have incorporated higher suction rates so that their units can also be used to perform

general-purpose suction. Some units are also being used for liposuction procedures.

Cost containment

Because uterine aspirators entail ongoing operational costs, the initial acquisition cost does not accurately

reflect the total cost of ownership. Therefore, a purchase decision should be based on issues such as life-cycle cost

(LCC), discount rates and non-price-related benefits offered by the supplier, and standardization with existingequipment in the department or hospital (i.e., purchasing all aspirators and/or collection containers from one

supplier).

An LCC analysis can be used to compare high-cost alternatives and/or to determine the positive or negative

economic value of a single alternative. Because it examines the cash-flow impact of initial acquisition costs and

operating costs over a period of time, LCC analysis is most useful for comparing alternatives with different cash

flows and for revealing the total costs of equipment ownership. One LCC technique—present value (PV)

analysis—is especially useful because it accounts for inflation and for the time value of money (i.e., money

received today is worth more than money received at a later date). Conducting a PV/LCC analysis often

demonstrates that the cost of ownership includes more than just the initial acquisition cost and that a small

increase in initial acquisition cost may produce significant savings in long-term operating costs. The PV is

calculated using the annual cash outflow, the dollar discount factor (the cost of capital), and the lifetime of theequipment (in years) in a mathematical equation.

The following represents a sample seven-year PV/LCC analysis for a uterine aspirator.

Present Value/Li fe-Cycle Cost An alysis

Assumptions

Operating costs are considered for years 1 through 7.

Dollar discount factor is 5%.

400 procedures are performed per year with single-use disposable collection containers, PVC

(polyvinyl chloride) tubing, and Yankauer tips.

Capital Costs

Aspirator with charger = $2,000

Total Capital Costs = $2,000

Operating Costs

Disposable collection containers = $3,200/year

Disposable PVC tubing = $2,400/year

Disposable Yankauer catheters = $400/year

Total Operating Costs = $6,000/year

PV = ($39,148)

Other costs not included in the above analysis that should be considered for budgetary planning include those

associated with the following:

Other disposables and accessories, such as bacterial filters, as well as optional accessories Contributions to overhead

As illustrated by the above sample PV/LCC analysis, the initial acquisition cost is only a fraction of the total

cost of operation over seven years. Therefore, rather than making a purchase decision based solely on the

acquisition cost of a uterine aspirator, buyers should consider operating costs over the lifetime of the equipment.

Prices for disposable tubing and catheters vary greatly depending on a number of factors, including type, size,

material, and manufacturer, as well as bulk-rate discounts. Many of these disposables can be used with a number

of manufacturers’ uterine aspirators. Disposables are usually more relevant to an LCC analysis for aspirators than

is the device itself—many device models can be used with various manufacturers’ disposables.

For further information on PV/LCC analysis, customized analyses, and purchase decision support, readers

should contact ECRI Institute’s SELECT™ Group.

Stage of development

Uterine aspiration is a mature and well-accepted technology. Advancements have included improved curet

design and ultrasound guidance to facilitate clearance and reduce injury to the uterine wall.
