IMPROVED DISPOSABLE THROAT SWAB

Technical Field

The utility model relates to the technical field of biomedical devices, and more particularly

relates to an improved disposable throat swab.

Background

Throat swab samples are collected by using medical swabs to dip a small amount of

secretions from pharynxes of human bodies. Because the human body breaths and eats food

through the oral cavity, various bacterial parasites are caused in the oral cavity. Moreover,

viruses transmitted by the respiratory tract are most likely to gather in the throat of the human

body. Virus types can be detected conveniently, rapidly and accurately by using the throat swab.

Therefore, collecting the samples by the throat swab is very important in etiological diagnosis.

At present, two common types of disposable throat swabs are used. One disposable throat

swab adopts an integrated design structure of a collecting rod and a collecting tube. However,

since the throat is deep, this collecting rod is relatively short, which is very inconvenient to

operate. Moreover, this throat swab cannot put two collecting rods into a same tube after the

collection, so that the experimental requirements cannot be met. Another throat swab adopts a

structure where the collecting rod and the collecting tube are separated. The collecting rod of this

throat swab is relatively long, so that the sample is convenient to collect. However, the throat

swab needs to be broken before being placed into the collecting tube; and moreover, some throat

swabs are difficult to break, thereby bringing about great inconvenience to the experiment. Some

throat swabs are provided with a breaking port, but if the patient suddenly coughs or vomits

during the collection, there will be a risk of breaking the collecting rod in the mouth; and

moreover, there may be risks such as splashing and pollution when the throat swab is broken for

being put into the tube.

Therefore, to provide an improved disposable throat swab which is convenient to operate,

convenient to collect samples and capable of effectively avoiding the breaking risk is a problem

to be urgently solved by those skilled in the art.

Description

Summary

In view of this, in order to solve the technical problems in the prior art that the throat swab

is inconvenient in collection and easy to break, the utility model provides an improved

disposable throat swab, which is simple in structure, reasonable in design, convenient to operate,

convenient to collect samples and capable of effectively avoiding the breaking risk.

To realize the above purpose, the utility model adopts the following technical solutions:

The improved disposable throat swab includes a throat swab body. The throat swab body

includes a swab stick and a collecting tube used to collect the swab stick. The swab stick

includes a handheld portion, a sampling portion, a connecting portion and a cotton ball. The

sampling portion is a hollow reducing tube structure. The bottom diameter of the sampling

portion is greater than the top diameter. The cotton ball is fixed to the bottom of the sampling

portion. The bottom of the handhled portion is clamped on the top inner wall of the sampling

portion and can slide along the inner wall of the sampling portion. Both ends of the connecting

portion are fixedly connected respectively with the handheld portion and the sampling portion,

which is used to prevent the handheld portion from being separated from the sampling portion.

It can be seen from the above technical solution that compared with the existing technical

solution, the utility model provides the improved disposable throat swab. Through a clamping

structure between the bottom of the handheld portion and the top of the sampling portion, the

handheld portion can be received inside the sampling portion, thereby realizing a telescopic

function of the swab stick. After the throat sample of the patient is collected by using the throat

swab, the swab stick does not need to be broken, and the handheld portion of the swab stick can

be pressed into the sampling portion by using a top cover of the collecting tube to press the

handheld portion of the swab stick, thereby reducing the length of the swab stick, so that the

swab stick is easier to place into the collecting tube, and the breaking risk and breaking

inconvenience of the throat swab collecting rod in the prior art can be avoided; and meanwhile,

the throat swab is convenient and rapid for collecting the sample. With the connecting portion,

the separation risk between the handheld portion and the sampling portion of the swab stick can

be avoided effectively, thereby further improving the safety of the throat swab in the operation

Description

process. The improved disposable throat swab of the utility model is not only simple in structure,

reasonable in design and simple in operation, but also convenient for collecting samples, capable

of effectively avoiding breaking risk, high in operation safety and good in application prospect.

Further, each collecting tube can receive two or more swab sticks.

The above technical solution has the beneficial effect that the manufacturing cost of the

throat swab can be reduced greatly.

Further, a divergent structure is formed at the bottom of the handheld portion. Clamp bulges

extending outwards are formed on the outer side all of the divergent structure. Slots are formed

on the top inner wall of the sampling portion. The clamp bulges are detachably connected into

the slots. Both ends of the connecting portion are fixed respectively on the divergent structure

and the sampling portion.

The above technical solution has the beneficial effect that the bottom of the handheld

portion of the swab stick can be ensured to have good contraction performance. In a case where

the sample is collected, the clamp bulges of the handheld portion are clamped in the slots of the

sampling portion, thereby being convenient for the operation personnel to collect the pharyngeal

sample. After the collection, the divergent structure is folded inwards under the action of an

external force, so that the clamp bulges can be separated from the slots, the handheld portion can

slide downwards along the hollow sampling portion, and the handheld portion is received into

the sampling portion, thereby realizing the contraction function of the swab stick.

Further, a plurality of clamp bulges are arranged. The plurality of clamp bulges are

distributed uniformly on a same circumferential surface along the outer side wall of the divergent

structure.

Further, a plurality of slots are arranged. The plurality of slots and the plurality of clamp

bulges have the same number and are arranged correspondingly.

The above technical solution has the beneficial effect that the frictional force at a junction

between the handheld portion and the sampling portion is increased, thereby avoiding the

separation or contraction of the handheld portion and the sampling portion in the operation

process.

Description

Further, the connecting portion is a connecting wire. Both ends of the connecting wire are

fixed respectively on the middle portion of the divergent structure and the bottom wall of the

sampling portion.

The above technical solution has the beneficial effect that the connecting portion is small in

occupied space, and the design reasonability of the throat swab is improved, so that the handheld

portion and the sampling portion are ensured not to separate easily in the operation process.

Further, the connecting wire is one of a nylon wire, a carbon wire and a PE wire.

The above technical solution has the beneficial effect that the connecting wire is high in

strength, so that the separation risk of the handheld portion and the sampling portion in the

operation process can be avoided, thereby further improving the stability of the overall structure

of the throat swab.
