Mouthpieces

One resin, however, can be considered as an exception to this. Although rarely recognised as a plastics material it can be fabricated into pipe mouthpieces, cigarette holders and various forms of jewellery. It may also be compression moulded and extruded. It is the fossil resin amber. 

Amber has been a much prized gem material for many millennia and has been found at Stonehenge, in Mycenaen tombs and in ancient European lake dwellings. In modern times it is u.sed for beads and other ornaments, cigarette holders and pipe mouthpieces. 

At one time the small fragments of amber produced during the fabrication and machining operations were used to produce varnishes. In 1880 they were first used in the production of Ambroid. This is made by pressing the fragments in a hydraulic press at temperatures somewhat above 160°C. The moulded product has a close resemblance to amber. A form of extrusion has also been used to produce amber rods for subsequent conversion into pipe and cigarette-holder mouthpieces.

Race the mouthpiece in your mouth and turn on the nebulizer. 

If the nurse is responsible for administering the medication by nebulization, it is important to place the patient in a location where he can sit comfortably for 10 to 15 minutes. The compressor is plugged in and the medication mixed as directed, or the prepared unit dose vial is emptied into the nebulizer. Different types of medication are not mixed without checking with the physician or the pharmacist. The mask or mouthpiece is assembled and the tubing connected to the compressor. The patient is placed in a comfortable, upright position with the mask over the nose and mouth. The mask must fit properly so that the mist does not flow up into the eyes. If using a mouthpiece instead of a mask, have the patient place the mouthpiece into the mouth. The compressor is turned on and the patient instructed to take slow, deep breaths. If possible, the patient should hold his breath for 10 seconds before slowly exhaling. The treatment is continued until the medication chamber is empty. After treatment, the mask is washed with hot, soapy water, rinsed well, and allowed to air dry. 

To properly instruct the patient in administration of drug via a metered-dose inhaler, the nurse must be aware of general instructions for use for all metered-dose inhalers and three common methods of rise holding the lips around the mouthpiece, holding the inhaler away from the mouth, and rising a spacer or extender. 

Place the mouthpiece into the mouth, close the lips tightly or position the mouthpiece 2 to 3 finger-widths from open mouth and tilt the head back. 

Rinse the extender and mouthpiece, if applicable, daily in warm water and store them away from heat. / To monitor the amount of drug remaining in the canister, test the canister by placing it in a container of water. 

Inhale as deeply as you can and then place your lips arcund the mouthpiece, making sure that you have a tight seal. Exhale asfordbly and as quickly as possible in one large huff. ... 

Corticosteroid Inhaled Powder—Hold the inhaler upright and twist off the cover. Twist the grip to the right as far as it will go, listen for the click, and then twist it back. Exhale and place the mouthpiece between lips slightly tilt head back and inhale deeply and forcefully. Remove inhaler from the mouth and hold breath for about 10 seconds. Rinse the mouth with water after each use to help reduce dry mouth and hoarseness. 

Describes equipment such as compressor, filter, tubing, aerosol cup, and mask or mouthpiece to be used for therapy, including rationale for use and need for electrical power source. 

BS7309 Mouthpiece assemblies for respiratory protective devices. 

A holder for a blowing tube can be made out of wire. This fits round the operator s neck, and holds the mouthpiece near the mouth. It is useful when engaged in complex operations which require the use of both hands for a long time. 

D NOTE Inhaled dry powder capsules require a different inhalation technique. To use a dry powder inhaler, it is important to close the mouth tightly around the mouthpiece of the inhaler and to inhale rapidly. 

The blowpipe is a metallic tube with a small nozzle and mouthpiece used to investigate minerals. Air is blown through the nozzle into the flame of a gas burner, causing the mineral sample to be heated to very high temperatures. 

Organic Lead. Following a single exposure to vapors of tetraalkyl lead compounds (approximately 1 mg/m3 breathed through a mouthpiece, 10-40 breaths of approximately 1 L volume) in four male subjects, 37% and 51% of inhaled tetraethyl and tetramethyl lead, respectively, were initially found in the respiratory tract, but a considerable percentage of these volatile compounds was lost through exhalation (Heard et al. 1979). Approximately 60-80% of the deposited tetraalkyl lead was absorbed by the lungs. 

Take care when handling sharps. When practical, use a mouthpiece or other ventilation device as an alternative to mouth-to-mouth resuscitation.

In a study designed to gather pharmacokinetic data, two healthy human volunteers were exposed to HFC-134a at 4,000 ppm delivered via a mouthpiece (Vinegar et al. 1997). The exposures were scheduled to last for 30 min. Blood samples were collected throughout the exposures. The exposures were abruptly terminated following an unexpected and uncontrollable rise in pulse rate in one subject and a drop in pulse rate and blood pressure and loss of consciousness in the second. This vasovagal response is sometimes observed... 

The metered dose inhalers consist of four basic functional elements, container, metering valve, actuator and mouthpiece. 

A mouthpiece. The mouthpiece may be used to control the direction of the aerosol cloud in the mouth and throat, in order to reduce drug deposition in the oropharyngeal cavities. De Boer et al. [55] use a so-called sheath flow to reduce mouth deposition. 

Open the dust cap of the HandiHaler by pulling it upwards, then open the mouthpiece. 

Firmly close the mouthpiece until a click is heard, leaving the dust cap open. 

Hold the HandiHaler dey ce with the mouthpiece upwards, press the piercing button completely in once, and release. This makes holes in the capsule and allows the medication to be released. 

Breathe out completely. Do not breathe into the mouthpiece at any time. 

Raise the HandiHaler dey ce to mouth and close lips tightly around the mouthpiece. 

After finishing taking the daily dose of tiotropium, open the mouthpiece again. Tip out the used capsule and dispose. Close the mouthpiece and dust cap for storage.
