Abstract

The utility model relates to a medical device. The utility model aims to solve the shortcomings of inaccurate sucked in or discharged liquid (such as blood) quantity, low inefficient performance, inconvenient storage of the existing rubber hollow ball type straw. The combined straw is composed of a straw with a scale, a non-toxic latex tube with a large expansion and shrinking force and a test tube whose one end is provided with an opening. An inner hole at one end of the latex tube matches with an external diameter of the straw with a scale in a sliding way, an inner hole at the other end matches with an external diameter of the test tube with an opening in a stationary way, and the straw with a scale can pass through the latex tube and is inserted into an inner cavity of the test tube. The combined straw which has the advantages of reasonable structural design and convenient operation can be operated with a single hand, can suck in or discharge the accurate liquid quantity, and is easy to be placed and kept.

Description

A kind of Combine suction tube

This utility model relates to medical apparatus and instruments, especially is the Combine suction tube of a kind of laboratory through need metering liquid (as: blood) commonly used.

At present, the hollow rubber ball formula suction pipe that hospital, laboratory are used, one termination of this suction pipe is a hollow rubber bulb that matches with the suction pipe internal diameter, utilize the hand distortion (forming positive and negative pressure in the hollow ball changes) of hollow rubber bulb, make the liquid in the vessel enter in the suction pipe or its discharge along the suction pipe inlet.The weak point of this suction pipe: 1, the amount of liquid in vessel sucks liquid and is difficult for grasping after a little while, and the liquid of urgently needed accurate quantification needs spended time long, and just operating rate slows down; 2, the rubber bulb of this suction pipe is what to separate with suction pipe, gives to deposit and makes troubles.

The purpose of this utility model provide a kind of suck or drain quantity is accurate, operating rate is fast, use, carry, deposit Combine suction tube easily.

Formation of the present utility model:

This Combine suction tube is by being with graduated suction pipe, the big latex tubing of nontoxic harmomegathus power, and open test tube three parts of an end constitute, and the measuring pipette lower end is provided with suction inlet, and the upper end is an opening, and a side on post surface, garden is provided with calibration data; Latex tubing is a both ends open, between the external diameter of lower ending opening and graded tube for being slidingly matched, between the external diameter of the endoporus of upper end open and test tube opening end for stationary fit, during assembling, the upper end of graded tube (opening) should and the closed end of test tube between a segment distance is arranged.The lower end of graded tube (tip) is the suction inlet of liquid, liquid can be in graded tube, left alone without helply between the upper port of pipe and the test tube inner chamber put upside down stagnate or flow, the forefinger of hands and mother refer to promote up and down test tube, test tube slides up and down along latex tubing lower end endoporus, makes in the top of its pipe intracavity produce positive/negative pressure and reaches and suck or drain.

Embodiment during this utility model is incited somebody to action in conjunction with the accompanying drawings further specifies:

Fig. 1 is a kind of population structure allocation plan of Combine suction tube,

Fig. 2 is the test tube structure chart in a kind of Combine suction tube,

Fig. 3 is the latex tubing structure chart in a kind of Combine suction tube,

Fig. 4 is the graded tube structure chart in a kind of Combine suction tube,

In the diagram zero, parts and position sequence number thereof:

1, suction pipe, 2, most advanced and sophisticated mouthful of the imbibition of suction pipe, 3, the opening of suction pipe, 3 ', the meter liquid scale of suction pipe, 4, latex tubing, 5, test tube, 6, the opening end of test tube.

This Combine suction tube is made of suction pipe 1, latex tubing 4, test tube 5; Suction pipe 1 is provided with most advanced and sophisticated mouthful 2 of imbibition, opening 3, and the two ends of latex tubing 4 are opening, and it is uncovered 6 that an end of test tube 5 is provided with, and the other end is a sealed end; For being slidingly matched, be stationary fit between the external diameter of the other end endoporus of latex tubing 4 and the opening end 6 of test tube 5 between the one end endoporus of the outer garden cylinder of suction pipe 1 and latex tubing 4, suction pipe 1 can pass in the inner chamber that latex tubing 4 is inserted into test tube 5.

One side of the outer garden cylinder of said suction pipe 1 be provided with meter liquid scale 3 '.

The imbibition of suction pipe 1 can be inserted in the open-top receptacle of liquid for most advanced and sophisticated mouthful 2, and when the imbibition body, the right hand is vertically held suction pipe 1, promotes test tube 5 up and down with thumb and forefinger, just can accurately suck or discharge required amount of liquid.

This Combine suction tube reasonable in design, easy to use, one-hand operation can suck or discharge more accurate liquid (as: blood) amount, and easily place and take care of.
