Aiming at the defects of the prior art, the utility model provides a highly pathogenic sample sampling device.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a highly pathogenic sample sampling device comprises a handle, a sleeve, a needle tube, an air bag, a sampling liquid bottle, a notch, a swab mounting slot, a vent nozzle and a swab, wherein the handle is provided with the sleeve; the rear end of the needle tube is fixedly provided with an air bag, and the rear end of the air bag is provided with a vent nozzle; the sampling liquid bottle is detachably arranged on the sleeve and is communicated with the needle tube; the front half part of the sleeve is provided with a gap, and the gap divides the front half part of the sleeve into an upper valve and a lower valve; the swab mounting slot is arranged at the front half part of the sleeve and is coaxial with the needle tube; the swab is arranged in the swab mounting slot; the center of the sampling rod of the swab is provided with a transfusion channel in a penetrating way; the swab is provided with a needle tube which is inserted into the infusion channel.

The utility model has the innovation points that the swab for sampling the virus is installed by adopting a special device, and the swab head can be safely and hygienically wetted during sampling, so that the virus sampling can be conveniently carried out on places needing to be detected in public places, the condition that the detection effect of insufficient virus adhesion caused by the drying of the swab head is not obvious is avoided, the condition that workers directly hold the swab is also avoided, and the infection risk is reduced.

Furthermore, the cross section of the swab mounting slot is arc-shaped, and the radius of the arc-shaped is 0.2-0.5 mm smaller than that of the sampling rod of the swab, so that the swab is clamped by the swab mounting slot after being inserted, and the swab is prevented from falling off.

Furthermore, the outer diameter of the needle tube is 1.0mm, and the needle tube is mainly used for conveying the sampling liquid into the infusion channel, so that the sampling liquid can flow to the swab head along the channel.

Furthermore, the length of the gap is the same as that of the swab mounting slot, so that the processing and the production are convenient, and the installation of the swab is also convenient.

Furthermore, the liquid in the sampling liquid bottle is normal saline which is usually used for preserving and transporting the virus and can keep the activity of the virus.

The utility model has the advantages that: the swab head can be wetted by the sampling liquid as required, so that virus sampling can be conveniently and quickly carried out on dry places in public places; staff (especially non-medical staff or prevention and control staff) do not need to directly hold the swab for sampling in a close distance, and the infection risk is reduced.

Detailed Description

The utility model is described in detail below with reference to the accompanying drawings:

in the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "front" and "rear" and the like are based on the directions or positional relationships shown in the drawings or the directions or positional relationships which are usually placed when the products of the present invention are used, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or the element to be referred must have a specific direction and a specific direction configuration and operation, and thus, the present invention is not to be construed as being limited.

As shown in fig. 1-3, a highly pathogenic sample sampling device comprises a handle 1, a cannula 2, a needle tube 3, an air bag 4, a sampling liquid bottle 5, a gap 6, a swab mounting slot 7, a vent nozzle 8 and a swab 9, wherein the cannula 2 is arranged on the handle 1, the needle tube 3 with the outer diameter of 1.0mm is arranged on the central line of the cannula 2, the rear end of the needle tube 3 is flush with the rear end of the cannula 2, and the length of the needle tube 3 is two thirds of the length of the cannula 2; the length of the sleeve 2 can be designed to be different according to the needs. The rear end of the needle tube 3 is fixedly provided with an air bag 4, the rear end of the air bag 4 is provided with a vent nozzle 8, when the air bag is used, the thumb presses the vent nozzle 8 to extrude, and the air bag 4 can automatically recover after being loosened.
