Abstract

The utility model discloses a water quality microorganism detection sampler which comprises a scale vacuum container, a sample feeding pipe, a side wall sample feeding port for a sample feeding needle, a sample feeding end grid sample feeding port, and a protection sleeve for the sample feeding needle, and is characterized in that the side wall sample feeding port for the sample feeding needle is arranged on the side wall of a needle point. In the utility model, the sample feeding needle capable of penetrating through a container stopper for one time is arranged on one end of the sample feeding pipe; a round opening is arranged on a point end near to the side wall of the needle, thus not only avoiding blocking during insertion, but also avoiding puncture of the container stopper; a plurality of sample feeding holes are arranged on the other end and the side wall, thus not only being capable of feeding, but also being capable of filtering so as to prevent a pipeline from blocking. When water samples are collected, pollution on the water quality during sampling process can be effectively avoided by means of negative pressure action of the vacuum container and the structure features of the sample feeding pipe.

Description

A kind of water quality Micro biological Tests sampling thief

Technical field: the utility model relates to the sampling apparatus of a kind of water examination in medical sector, the environmental administration, directly relates to water quality Micro biological Tests sampling thief.

Background technology: water quality Micro biological Tests aseptic technique is strict especially.Sampling thief promptly is the special container that a kind of health and epidemic prevention, environmental administration are used for doing water examination.And the sampling thief that is used for the water quality Micro biological Tests has more singularity, and that is exactly aseptic, pollution-free, more will all will guarantee sterile working from sampling, censorship, the whole flow process of check, avoids water sample to pollute.Traditional sampling has plenty of the vacuum of utilization machine sample container is vacuumized, and connects aseptic water pipe to (as well water, sewage, tap water etc.) under water and takes a certain amount of water sample; Having plenty of direct filling of manual operations gets.But there is certain defective in these methods, and equipment is heavy, carry inconvenience, need charged source, vacuum machine, connect water pipe and be difficult for sterilization, easily vessel port are caused artificial pollution etc. in the operation.And above-mentioned drawback has been avoided in invention use of the present utility model, has improved work efficiency.

Summary of the invention: the purpose of this utility model will provide a kind of water quality Micro biological Tests sampling thief exactly, and it can effectively avoid in the sampling process pollution to water quality, and can be fit to the collection at various water sources.

A kind of water quality Micro biological Tests sampling thief has scale vacuum Container, sample introduction pipe, sample introduction needle sidewall injection port, sample introduction end grid injection port, sample introduction needle protective jacket.It is characterized in that sample introduction needle sidewall injection port is located at the needle point sidewall.

The utility model had both guaranteed the smooth sampling of the sample introduction mouth of pipe, had guaranteed the sterile working requirement of whole sampling process again.

Description of drawings: Fig. 1 is the structure principle chart of the utility model vacuum Container; Fig. 2 is the structure principle chart of sample introduction pipe; Fig. 3 is the mechanism principle figure after sample collecting finishes.The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment: accompanying drawing shows the structure of a kind of water quality Micro biological Tests of the utility model sampling thief.A kind of sampling thief has disposable band scale vacuum Container 1, sample introduction pipe 2, sample introduction needle sidewall injection port 3 and injection port other end sidewall and establishes netted sample introduction osculum 4, sample introduction needle protective jacket 5.The course of work of the present utility model is that disposable sample introduction water inlet tube mouth end 4 is put into earlier needs the sample underwater.Other end sample introduction needle is pulled up protective jacket and is penetrated the vacuum Container from the bottle stopper recess, sucks the q.s water sample by negative pressure, waits to observe and pulls up sample introduction needle after having gathered, and packs up the sample introduction pipe, finishes aseptic sampling process.

Claims

1. water quality Micro biological Tests sampling thief, have scale vacuum Container (1), sample introduction pipe (2), sample introduction needle sidewall injection port (3), sample introduction end grid injection port (4), sample introduction needle protective jacket (5), it is characterized in that sample introduction needle sidewall injection port (3) is located at the needle point sidewall.
