An object of the utility model is to provide a inhale put with integrative microorganism inoculator of coating integrates the design with imbibition burette and spreader integration to improve strain inoculation operating efficiency, reduce the inoculation pollution risk that many apparatus used and bring. The utility model discloses can absorb and drip quantitative fungus liquid to the coating head that becomes through flexible body of rod bending shape is with even coating of fungus liquid.

A suction-release and coating integrated microorganism inoculator comprises an inner pipe and an outer pipe, wherein the inner pipe comprises a front part, a middle part and a tail part which are integrally connected; the front part is a conical hollow dripper, the middle part is a hollow columnar rod body, and the tail part is an extrudable dropper cap; the upper end and the lower end of the columnar rod body are respectively provided with a first bulge and a second bulge;

the upper part of the outer pipe is provided with a bayonet structure for sheathing the bulge on the inner pipe; the middle part of the spiral fold is provided with a bendable spiral fold, the upper part of the spiral fold is provided with a sharp mouth bayonet which is vertical to the outer tube and used for limiting the lower part of the spiral fold after the spiral fold is bent.

When the spiral fold is used for coating after being bent, the two ends of the spiral fold form 90 degrees.

The length of the columnar rod body in the inner pipe is larger than that of the dripper, so that a certain amount of bacteria liquid can be absorbed.

The length of the inner tube is longer than that of the outer tube.

The microorganism spreader is made of PP materials and is disposable and comprises an inner tube and an outer tube.

The length of the outer tube under the spiral folds is more than 3 cm.

The lower part of the spiral fold on the outer pipe is provided with a longitudinal notch for clamping the sharp mouth bayonet after the spiral fold is bent.

The utility model discloses a flexible design unites two into one required pipettor and coating rod in the operation with traditional inoculation, and operation labour saving and time saving is convenient and reduce the potential pollution risk of many apparatus operation, improves experimental efficiency, overcomes the operation defect of current experimental apparatus, but extensively is applicable to in the microorganism cultivation operation in biochemistry, molecular biology, health inspection field.

Detailed Description

A suction-discharge and coating integrated microorganism inoculator comprises an inner pipe and an outer pipe.

As shown in fig. 1, the inner pipe is composed of a front part, a middle part and a tail part which are integrally connected; the front part is a conical hollow dripper 1, the middle part is a hollow columnar rod body 2, and the tail part is an extrudable dropper cap 3; the upper end and the lower end of the columnar rod body 2 are respectively provided with a first bulge 4 and a second bulge 5.

The length of the columnar rod body in the inner pipe is larger than that of the dripper.

As shown in fig. 2, the upper part of the outer tube is provided with a bayonet structure 6 for sheathing the bulge on the inner tube; the middle part of the spiral fold is a bendable spiral fold 8, and the upper part of the spiral fold is provided with a sharp-mouth bayonet 7 which is used for limiting the lower part of the spiral fold after the spiral fold 8 is bent.

Because the sharp mouth bayonet 7 is perpendicular to the outer tube, when the spiral fold 8 is bent for coating, the two ends of the spiral fold are at 90 degrees, as shown in fig. 4.

The lower part of the spiral fold on the outer pipe is provided with a longitudinal notch for clamping the sharp mouth bayonet after the spiral fold is bent.
