Abstract

The utility model relates to a disposable plastic liquid transferring pipe. The utility model is composed of a liquid storing pipe and a suction ball which are made of plastic and are made into a whole. The liquid storing pipe can be made into a thick pipe, or a slim pipe, or a miniature pipe; scales can be arranged on the pipe, and can be not arranged on the pipe. The suction ball forms various shapes such as acylindrical shape (a cask shape), or a spherical shape, or an ellipsoidal shape, etc. The plastic is polyethylene material. The utility model has the characteristics of easy fabrication, low material consumption, no leakage, disposable use, hygiene and safety, etc., transportation damage and cross contamination are avoided, and the utility model is free from the influence of corrosion.

Description

The disposable plastic pipette

The utility model relates to pipette, also claims suction pipe, is widely used in hospital clinical check, isotope and puts and exempt from and the usefulness of R﹠D institution's sampling.

Put and exempt from hospital clinical check, isotope, and do the experiment sampling in the enterprises and institutions such as R﹠D institution or relevant chemical industry, food, mine, pipette, or title suction pipe are a kind of indispensable apparatus.Existing pipette mainly is made up of the rubber bulb pump that glass liquid storage tube and glass liquid storage tube match, and its feature is repeated multiple times to use, but the major defect of its existence is: rubber ball is easily by acid and alkali corrosion, and is aging; Clean trouble, be difficult for cleaning; Glass tube is damaged easily, and especially when transportation, loss is big; Be easy to generate seepage at glass tube and rubber ball junction.

The purpose of this utility model is that designing a kind of is raw material with plastics, overall structure, and material consumption is low, disposable pipette easy to manufacture.

The technical scheme of the utility model disposable plastic pipette is: be made up of liquid storage tube and suction ball, it is characterized in that the liquid storage tube made from plastics and inhaling ball is an integral body.

Disposable plastic pipette of the present utility model is spherical transition or chamfered transition at liquid storage tube with the junction of inhaling ball.

Disposable plastic pipette of the present utility model, its so-called suction ball is cylinder or different shapes such as spheroid or spheroid, so-called plastics are polyethylene raw materials.

The utility model discloses a kind of plastics and make the pipette of unitary construction.Compared with the prior art, have rational in infrastructurely, easy to manufacture, material consumption is low, avoids transportation damaged, can seepage, and disposable use, safe and sanitary are avoided cross pollution, are not subjected to characteristics such as corrosion influences.

Below in conjunction with Fig. 1 one Fig. 5 embodiment of the present utility model is done detailed explanation.

The utility model relates to pipette, i.e. suction pipe is that hospital clinical check, isotope are put and exempted from or the common tool of scientific experiment sampling.Existing products is that glass tube and two of rubber balls link, and existing is raw material with plastics, is raw material by polyethylene mainly, and single injection-molded is processed laborsavingly, and shape is random, the big suction amount of plain edition extra heavy pipe as shown in Figure 1, and there is metering scale 6 on the surface; As Fig. 2, elongated tubular shown in Figure 3, there is metering scale on the surface, or does not establish scale, but can be very long, draws the liquid in the contour container in the bottle end; Also can be made into miniature tube, get sample usefulness, therefore make a series of different lengths and difform product as Fig. 4.The basic structure of pipette is to be divided into liquid storage tube 2 and to inhale ball 4, and the shape to liquid storage tube 2 is described above, and the shape of inhaling ball is generally drum shape, and appearance is cylindrical, and an end is a spheroid, and the other end is connected spherical 7 transition of employing or inclined-plane 3 transition with pipe.Inhale ball if not drum (or claiming cylinder) shape, also can be made into other different shapes such as sphere, elliposoidal.The 1st, the liquid storage tube cavity volume, the 5th, inhale the ball cavity volume, the 8th, long tube closes up.

Claims

1, disposable plastic pipette is made up of liquid storage tube and suction ball, and it is characterized in that the liquid storage tube made from plastics (2) and inhaling ball (4) is an integral body.
