It should be noted that, the grinding ring 21 may be an integral structure with the first connecting rod 2, or may be an independent structure sleeved on the first connecting rod 2; the grinding ring 21 may also be spirally distributed on the surface of the first connecting rod 2.

Specifically, stretch into the sampling pipe through the in-process of breaking to S type connecting rod 3 through breaking groove 32, first connecting rod 2 supports the sampling pipe mouth of pipe, and the setting of grinding ring 21 can increase first connecting rod 2 and the orificial frictional force of sampling pipe, and then can further improve the rupture efficiency, realizes the quick rupture of S type connecting rod 3 to save sampling head 1 in the sampling pipe fast.

Referring to fig. 5, a schematic cross-sectional view of a throat swab sampling head 1 according to an embodiment of the present application is shown. As shown in fig. 5, the sampling head 1 has an arc surface on the side close to the second connecting rod 4, and the sampling head 1 has a flat surface on the side far from the second connecting rod 4.

Specifically, the sampling head 1 is in a water drop shape, one end of the sampling head is connected with the first connecting rod 2, and the other end of the sampling head is a sampling end. During sampling, the position of the sampling head 1 is lower than that of the second connecting rod 4, and one side far away from the second connecting rod 4 is used for contacting with the pharynx of a person to be sampled. One side of the sampling head 1 far away from the second connecting rod 4 is set to be a flat surface, so that the contact area between the sampling head 1 and the pharyngeal portion of a sampled person can be increased, more body fluid samples can be obtained, and the probability of successful sampling is increased.

Referring to fig. 3 and 4, a cross-sectional view and a bottom view of a throat swab sampling head 1 according to an embodiment of the present application are shown. As shown in fig. 3 and 4, the flat surface of the sampling head 1 is provided with a plurality of concave portions.

The arrangement of the concave part can improve the convenience of storing the pharyngeal body fluid sample of the sampled person during sampling.

In the embodiment of the application, the surface of the sampling head 1 is provided with a sampling layer 11, and the sampling layer 11 is concave in a concave part to form a liquid storage groove 12.

Specifically, the sampling layer 11 may be absorbent cotton, the surface of the sampling head 1 may be provided with protrusions, the absorbent cotton is wrapped on the surface of the sampling head 1, and the protrusions on the surface of the sampling head 1 enhance the connection between the absorbent cotton and the sampling head 1; the absorbent cotton may also be adhered to the surface of the sampling head 1. At the position of the concave part of the sampling head 1, absorbent cotton is pressed into the concave part by external force to form a liquid storage groove 12. In the sampling process, when the sampling layer 11 contacts the pharyngeal portion of the sampled person, the sampled person needs to apply force to rub the pharyngeal portion so as to be stained with the body fluid of the pharyngeal portion of the sampled person to the surface of the sampling layer 11, and when the force application of the sampled person is smaller, the body fluid sample stained with the surface of the sampling layer 11 is less, and the sampling failure can be caused. Under the condition that the force applied by the sampling personnel is small, the liquid storage groove 12 can provide more storage space for the body fluid sample, so that the body fluid sample amount is increased, and the sampling reliability is improved.

In the embodiment of the application, the rear end of the second connecting rod 4 is also connected with a holding handle 5, and the holding handle 5 is flat.

In practical application, in order to ensure the sanitation and safety of sampling personnel, the sampling personnel generally wear protective gloves with both hands, and at this time, the flexibility of hand operation can be influenced. Because the area of the holding handle 5 is larger than that of the holding part of the common swab rod, sampling staff can conveniently draw the pharyngeal swab from the pharyngeal swab packaging bag when wearing the protective glove, and the pharyngeal swab can be held more stably when sampling work is carried out.

Specifically, the handle 5 is perpendicular to the flat surface of the sampling head 1. When the sampling personnel hold the handle 5 with fingers, in order to meet the sampling requirement, the throat swab needs to be stretched into the throat of the sampled personnel under the condition that the sampling head 1 is kept below the second connecting rod 4, and at the moment, the flat surface of the sampling head 1 can be attached to the throat of the sampled personnel. The handle 5 is held with the setting that 1 flat face of sampling is mutually perpendicular, makes sampling personnel under the nature state of holding, just can satisfy sampling head 1 and be in the second connecting rod 4 below, and the laminating of 1 flat face of sampling head is by the sampling demand of sampling personnel pharyngeal, has improved sampling personnel and has held the comfort level of pharyngeal swab.

In summary, in the embodiment of the application, the S-shaped connecting rod is arranged on the throat swab, one end of the S-shaped connecting rod is connected with the sampling head through the first connecting rod, and the other end of the S-shaped connecting rod is connected with the second connecting rod. When the pharyngeal swab extends into the pharyngeal portion of a person to be sampled for sampling, the second connecting rod is positioned above the tongue of the person to be sampled, the first connecting rod and the sampling head are positioned below the second connecting rod, the S-shaped connecting rod is more fit with the pharyngeal portion of the person to be sampled, and the influence of the tongue and the chin of the person to be sampled in the sampling process is avoided; in addition, as the sampling head and the second connecting rod are in a parallel state, the risk of breakage of the swab rod when sampling force is applied by sampling personnel is reduced, and the sampling failure probability is reduced.
