Syringe, disposable

As liquids in disposable cartridges or disposable syringes diat contain a specific amount of a drug in a specific volume, for example, meperidine 50 mg/ mL. After administration, die cartridge or syringe is discarded. 

The physician orders diazepam 5 mg IM. The drug is available as a 2-mL disposable syringe labeled 5 mg/mL. 

Whenever the dose to be administered is different from that listed on the label, the volume to be administered must be calculated. To determine the volume to be administered, die formula for liquid preparations is used. The calculations are die same as tiiose given in the preceding section for parenteral dru s in disposable syringes or cartridges. 

Add wood furnish (384 g, moisture content 6.02%) to the bowl of a rotary blade paddle mixer (such as a Kitchen-Aid KSM90) and agitate at the lowest speed setting. Add Mondur 541 (7.39 g, 1.9% w/w, a polymeric diphenylmethane diisocyanate of 31.5% NCO, Bayer) dropwise over a 5-min period using a disposable syringe. Continue blending for an additional 10 min and then transfer the blend to an 8 x 8 x 2 -in. metal form at the bottom of which is a metal plate which fits inside. The resin-coated furnish is evenly spread inside the form and another metal plate is placed on top. All parts of the form and plates are presprayed with mold release. The completed form assembly is placed into a hydraulic press (such as a model PW-22 manufactured by Pasadena Hydraulics) with platens heated at 350°F. The furnish is then pressed between the two form plates to a thickness of j in. Press controls are used to ensure consistency of board thickness. The assembly is heated for 4 min. before demolding the cured wood panel. 

Details are given of ways of obtaining energy from the pyrolysis of disposable syringes. The waxy product was chemically modified with maleic anhydride and tested in the processing of PP/LLDPE blends in a rheometer or twin-screw extruder. Compatibility of components in binary or ternary blends and DSC results are discussed. 35 refs.

Attach a 25-mm Acrodisc nylon Alter cartridge to the LuerLok fitting of a 10-mL disposable syringe, and transfer approximately 5 mL of filtrate to the syringe barrel. 

Salmona et al. [66] used El and CIMS to identify benzothiazole derivatives leached into injections by rubber plunger seals from disposable syringes. One of the compounds was used as a rubber vulcanisation accelerator, and four others were formed during syringe sterilisation with ethylene oxide. Applications of hyphenated chemical impact mass-spectrometric techniques are described elsewhere GC-MS (Section 7.3.1.2), for polar and nonpolar volatile organics, SFC-MS (Section 13.2.2) and TLC-MS (Section 7.3.5.4). 

After 30 h from inoculation, NaOH solution (4 p, 40 ml) was injected into the Wavebag with a sterile disposable syringe. 8.8 g of fluvastatin-Na was dissolved in 88 mL of methanol. At 48, 74, 120, and 192 h after inoculation with spores, fluvastatin solution (22 mL) was supplemented to the culture via the sampling port and a sterile disposable 50 mL syringe. The degree of conversion was measured by analytical RP18-HPLC with diode array detection. ... 

Increasingly there is a need to evaluate simple physical properties such as solvent imbibition in a more rapid manner for high-throughput materials studies, or for real-time evaluation. Recently this issue has been addressed and a very elegant solution developed [75] based on earher work [76, 77]. In this a polypropylene disposable syringe containing a known mass of polymer is suspended from a microbalance and the balance reading set to zero. A reservoir of the solvent to be inves-...

The submitter used a balloon attached by 1" of rubber pressure tubing to the barrel of a plastic disposable syringe bearing a 2"-needle through the septum. 

Novolin is available in four formulations Regular (R), NPH (N), Lente (L), and Novolin 70/30. They correspond to the several formulations of Humulin. Novolin 70/30, Novolin N, and Novolin R are supplied in prefilled cartridges and in prefilled disposable syringes. Velosulin BR is a sterile solution of human insulin (rDNA origin) in a phosphate buffer.

Using a sterile, nonpyrogenic disposable syringe and needle, inject 5.0 ml of pyrogen-free water to reconstitute the reagent. Reconstitution is more rapid if reagents are at room temperature. 

Rubber Stoppers, cap liners, and bulbs for dropper assemblies used in the pharmaceutical industry are made form rubber. The rubber stopper is used primarily for multiple-dose vials and disposable syringes. The rubber polymers most commonly used are natural, neoprene, and butyl rubber. As certain performance expectations... 

Urine (5 ml) urine spiked with 0.2% (v/v) isopropylamine is placed in a screw-capped 15-ml vial [28]. Pelleted potassium hydroxide (3 g) is added before sealing the vial with an airtight polytetrafluoroethylene-lined septum cap. Potassium hydroxide raises the pH of the sample to ensure that the amines are present as volatile bases. The vial is heated in an aluminium block at 90 C for 20 min. While still in this block, 2 ml head-space gas is withdrawn through the septum with a disposable syringe and injected immediately on the gas chromatography column. The operating temperatures of the column, injector port and detector unit are 70 C isothermal, 150 C and 200 C, respectively, with nitrogen carrier gas at 60 ml/min. This allows quantification of TMA and other amines. TMA N-oxide is measured after quantitative reduction into TMA. For this, titanous chloride (30%, w/v 0.2 ml) is added to 2 ml urine in a screw-capped vial and incubated for 30 min at room temperature. The sample is then diluted ten-fold with distilled water and analysed as described above. The result represents the sum of TMA and TMA N-oxide present in the sample. 

Further, they can be used for medical purposes, such as press-through packages, disposable syringes, liquid medicine vials, and infusion bags. They are suitable for electric or electronic materials, such as wire coating. In addition, packaging films, such as wrapping films, stretch films, shrink films, and blister packs can be produced.
