Technical field

The utility model relates to the field of oral cavity sampling devices, in particular to a throat swab sampling device.

Background technique

Respiratory infections are usually spread through the respiratory tract, and the pharynx is where most viruses accumulate. When confirming the virus type, throat swab specimens are usually collected for bacterial culture or virus isolation to quickly confirm the virus type. Existing throat swab sampling cotton swabs are usually medical sterile cotton swabs, which are dipped in oral and nasal secretions from the subject's throat to collect throat swab specimens. The anatomy of the posterior wall of the oropharynx is an arc structure, and the base of the tongue is a convex arc shape. However, the existing sampling rod head is straight, short and narrow and cannot contact the posterior pharyngeal wall to the maximum area. If the collection depth is not enough, the patient's posterior pharyngeal wall will not be collected. Secretions that cannot be detected, resulting in test failure or weakly positive test results; in order to collect a sufficient amount of viral vectors for testing, it can only be collected by increasing the number of repeated wipes; oral mucosal lesions and deformities of the posterior oral wall after oral surgery In patients with fragile oral mucosa, repeated wiping increases the chance of infection. For infants and young children, due to the incomplete physical development of children, children's bite muscles and mandibles cannot support the mouth opening for a long time, or they are unable to fully cooperate with the doctor due to fear of making noise. Secondly, the oral mucosa is relatively soft, especially for infants. The oral capacity of young children is small, and using conventional adult sampling cotton swabs can easily damage the oral mucosa of infants and young children.

The maximum diameter of the bottom end of the anti-pressure part is larger than the diameter of the tooth's biting part. The diameter of the hand-held part is larger than the maximum diameter of the bottom end of the anti-pressure part. Preferably, the hand-held part also includes anti-slip particles. In addition, when necessary, an external light source can be shined into the through hole of the anti-bite piece to achieve visual sampling.

As shown in Figure 5, the anti-bite piece of this embodiment is suitable for use by infants and young children of different ages. As shown in Figure 5A, when the infant is young, the anti-bite piece is put into the mouth, and the baby puts the anti-bite piece into the mouth. It is used as a pacifier for sucking, but due to the overall hardness of the anti-bite piece, the baby cannot suck the anti-bite piece flat in a short time, giving the sampling brush a space to operate, while ensuring that the pharynx is exposed without interference from the tongue. The top of the anti-bite piece is a through hole and hollow design. In addition to allowing the sampling brush to have room to operate, it also allows the operator to see the baby's pharynx, making it easier to operate. Insert the sampling brush into the mouth through the anti-bite piece, place the brush head in the pharynx, clean the pharynx and sample, then take out the sampling brush, press the push rod, so that the brush head falls off and falls into the storage tube. The anti-pressure part of the anti-bite piece in this embodiment is longer than the pacifier, so as to expose the baby's pharynx.

As shown in Figure 5B, when using an anti-bite piece for older infants or younger children, you can bite the bite part with your teeth and place your tongue under the anti-pressure part, and use the anti-bite piece to assist them. Open and hold, and also insert the sampling brush into the mouth through the anti-bite piece to sample the pharynx. When using the anti-bite piece here, you can also slightly move the position of the top of the anti-bite piece so that you can see the pharynx and sample. shall prevail. Insert the sampling brush into the mouth through the anti-bite piece, place the brush head in the pharynx, clean the pharynx and sample, then take out the sampling brush, press the push rod, so that the brush head falls off and falls into the storage tube.
