Abstract
Disclosed is a sucker with a floater arranged inside, pertaining to the medical examination device. Wherein, a floater 3 is arranged inside the sucker 1; a through-hole 7 is arranged in the center of the floater 3. When the sucker sucks liquid, the upper surface of the floater 3 is tangent with the concave liquid surface 2; a cover 5 is arranged on the top of the sucker 1; a sucking hole 4 is arranged on the cover 5; a calibration line 6 is arranged on the outer surface of the sucker 1.The utility model solves the problem that the ordinary sucker is often disturbed by the bubbles on liquid when the ordinary sucker sucks the liquid, thus making the operations of measuring and moving the liquid become more simple and accurate.
Description
This utility model belongs to the medical test apparatus, a kind of interior float suction pipe.
At present, common suction pipe is an elongated cylindrical, and mouth transition gradually is the glass tubing that conical external surface has graduation mark.Its major defect is: 1 at amount liquid with move and disturbed by bubble, and 2, when reading the suction pipe scale, influenced by concave meniscus and error is often arranged.
In order to overcome above defective, the purpose of this utility model is a kind of interior float suction pipe of design, can and move the interference of getting rid of bubble and concave meniscus in the liquid process effectively at amount liquid.
In order to realize the foregoing invention purpose, this utility model adopts following technical scheme:
Float suction pipe 1 outer surface has graduation mark 6 in described, and float 3 is housed in it, and there is through hole 7 in float 3 central authorities, and float 3 upper surfaces and concave meniscus 2 are tangent during imbibition, and suction pipe 1 top covers 5, and the hole 4 of suction is arranged on the lid 5.
During use, sucker mouth is stretched in the reagent, air-breathing from inhaling hole 4 with inhaling ball, reagent promptly holds up float 3 after entering suction pipe 1, bubble then along through hole 7 or and float 3 and the slit of suction pipe wall float to concave meniscus more than 2.During reading, concordant institute is as the criterion to graduation mark 6 with float 3 lower edges, and does not use suction pipe mouth amount liquid.
Owing to adopt above technical scheme, the utlity model has following superiority:
The float suction pipe can and move in the process of liquid and get rid of the interference of bubble and concave meniscus effectively at amount liquid in described, and does not use suction pipe mouth amount liquid, thereby has improved the accuracy of operation to a great extent.
Below in conjunction with the description of drawings specific embodiment:
Fig. 1: interior float suction pipe overall structure sketch map.
As shown in the figure: the 1-suction pipe; The 2-concave meniscus; The 3-float; 4-inhales the hole; The 5-lid; The 6-graduation mark; The 7-through hole.
As Fig. 1: suction pipe 1 is made by glass, the calibrated graduation mark 6 that marks, lid 5 and on suction hole 4 be the plastics integrally casting, float 3 is made for low-density cork, get through 7 backs, hole and in its outer surface and through hole 7, use red plastics liquid plastic-blasting, cork is completely enclosed within the plastic film.Float 3 is packed in the suction pipe 1, and closing the lid 5 gets final product again.
Claims (1)
1, a kind of interior float suction pipe, suction pipe 1 outer surface has graduation mark 6, it is characterized in that: in the suction pipe 1 of float suction pipe float 3 is housed in described, there is through hole 7 in float 3 central authorities, float 3 upper surfaces and concave meniscus 2 are tangent during imbibition, and suction pipe 1 top covers 5, and the hole 4 of suction is arranged on the lid 5.
