Abstract
The utility model relates to the field of medical instruments, in particular to an uncapping prevention type elastomer piston used for blood sampling. The uncapping prevention type elastomer piston comprises an elastomer piston. The elastomer piston is composed of a piston cap, a piston neck and a piston tongue, and is characterized in that the piston neck is divided into an upper piston neck and a lower piston neck, and elastomer saw teeth are arranged on the upper piston neck and the lower piston neck, and are uniformly distributed along a cylindrical surface circumference of the outer side of the piston neck. By the aid of the elastomer saw teeth arranged on the outer side of the piston neck, basic functional requirements of sealing can be met by the elastomer piston, the elastomer piston is not easy to fall from a blood sampling tube and has the function of uncapping prevention, and accordingly pollution and waste are avoided. The uncapping prevention type elastomer piston is particularly applicable to laboratories and blood analysis rooms in hospitals, and is simple in structure and convenient to use.
Description
Technical field
The utility model relates to medical instruments field, refers to particularly a kind of anticreep shape for hat blood-sample withdrawal elastic piston.
Background technology
At present, in various laboratories or the blood-sample withdrawal elastic piston that uses of hospital analysis room, because piston body adopts circular configuration, elastic piston is come off from heparin tube, cause polluting or waste, cause certain difficulty operating for the user of service.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, and a kind of anticreep shape for hat blood-sample withdrawal elastic piston is provided.
The technical solution of the utility model is: a kind of anticreep shape for hat blood-sample withdrawal elastic piston, it comprises the yielding movable cock body, described yielding movable cock body is made of cock cap, plug neck and plug tongue, it is characterized in that: described plug neck comprises plug neck top and plug neck bottom, and being equipped with the elastic body sawtooth on described plug neck top and plug neck bottom, described elastic body sawtooth distributes along the cylinder even circumferential in the plug neck outside.
Elastic body sawtooth described in the utility model and elastic piston one-shot forming in forming process do not need other adhesion.
The utlity model has simple in structurely, easy to use, it can make elastic piston satisfy the basic function requirement of sealing, and be difficult for coming off from heparin tube, have anti-function of raising one's hat, thereby avoid polluting and waste, be specially adapted to laboratory and hospital's blood analysis chamber use.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
As shown in Figure 1, a kind of anticreep shape for hat blood-sample withdrawal elastic piston, comprise yielding movable cock body 1, yielding movable cock body 1 is made of cock cap 2, plug neck 3 and plug tongue 4, described plug neck 3 comprises plug neck top and plug neck bottom, outer upper at plug neck 3 is provided with elastic body sawtooth 5.1, is provided with elastic body sawtooth 5.2 in the outer lower portion of filling in neck 3, and elastic body sawtooth 5.1 and the 5.2 cylinder even circumferentials along plug neck 3 outsides distribute.
Elastic body sawtooth 5.1 in the present embodiment and 5.2 and yielding movable cock body 1 one-shot forming in forming process does not need other adhesion.
The elastic body sawtooth of present embodiment by being provided with in the piston body neck outside, can make the elastic piston body satisfy the basic function requirement of sealing, and be difficult for coming off from heparin tube, has anti-function of raising one's hat, thereby avoid polluting and waste, be specially adapted to laboratory and hospital's blood analysis chamber use, and simple in structure, easy to use.
