Description

Negative pressure type throat swab sampler

Technical Field

The utility model belongs to the field of medical detection equipment, and particularly relates to a negative pressure type throat swab sampler.

Background

The normal oral cavity normal flora is cultured in the pharyngeal isthmus of a normal person, no pathogenic bacteria grow, the bacteria in the pharyngeal portion generally come from the outside, no disease is caused under normal conditions, but the disease is caused by the reduction of the systemic or local resistance of a body and other external factors such as infection and the like. The bacteria culture of the pharyngeal swab can separate out pathogenic bacteria, and is helpful for diagnosing diphtheria, suppurative tonsillitis, acute pharyngolaryngitis and the like. When taking secretion from pharynx and tonsil for bacterial culture or virus isolation, using a long sterilized cotton swab in the culture tube to wipe secretion from the palatine arches on both sides and pharynx and tonsil with a sensitive and gentle motion for sampling. Therefore, in order to detect the respiratory disease virus type, the virus type can be detected conveniently, quickly and accurately by using the pharyngeal swab.

In order to obtain a higher sampling positive rate, besides the skilled sampling skill of the sampling doctor, a cotton swab is required to collect more bacteria or viruses so as to improve the detection rate. The traditional cotton swab has no adsorption capacity, and after the wet cotton swab is smeared, bacteria or virus collection can be influenced due to the fact that liquid on the surface of the cotton swab is saturated or oral and throat body fluid exists, so that the detection of the positive rate is too low, or a false negative conclusion appears after detection, and therefore the infection prevention and control and clinical diagnosis are influenced.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a negative pressure type throat swab sampler with a simple structure, which can delay the duration of negative pressure, increase the sample collection amount, and improve the detection rate, so as to solve the above problems.

In order to achieve the purpose, the technical scheme of the utility model is realized as follows:

Further, the buffer is absorbent cotton located at any position of the hollow inner cavity of the swab rod.

The buffer piece can also be made of other similar absorbent cotton materials, namely, the buffer piece has air gaps and can be used for breathing, and meanwhile, the buffer piece can rent the hollow cavity of the swab rod to be slightly blocked, so that the time for the negative pressure suction head to recover the original state is prolonged, and the negative pressure is prevented from instantly disappearing.

Further, the buffer piece comprises a connecting piece with a hollow tubular structure and absorbent cotton arranged in a hollow inner cavity of the connecting piece; the swab rod comprises a swab rod A section connected with the negative pressure suction head and a swab rod B section connected with the swab head, and the swab rod A section and the swab rod B section are connected through the connecting piece.

Further, the connecting piece is detachably connected with the section A of the swab rod and the section B of the swab rod through threads.

Furthermore, internal threads are arranged at two ends of the connecting piece, and external threads matched with the internal threads of the connecting piece are arranged on the section A of the wiper rod and the section B of the wiper rod.

Further, the buffer is provided on the swab rod at a position near the swab head.

The absorbent cotton can delay the duration of negative pressure, and can absorb the liquid sucked back to prevent the liquid from being sucked upwards into the section A of the swab rod; in addition, the section A of the wiper rod is detachably connected with the section B of the wiper rod through a buffer piece, so that the section A of the wiper rod can be uniformly recycled and disinfected, and resources can be recycled.

Further, the packaging tube comprises a tube body and a detachable tube cap; a supporting block is arranged in the inner cavity of the pipe orifice of the pipe body, and a through hole for the sampling swab to pass through is formed in the supporting block; a detachable fixed block clamped on the supporting block is fixed on the swab rod close to the negative pressure sucker.

Furthermore, the fixed block is a cylindrical structure provided with external threads, and the inner wall of the through hole of the supporting block is provided with internal threads matched with the external threads of the fixed block.

Furthermore, the pipe body and the pipe cap are detachably connected through threads, a sealing gasket is arranged at the joint, and the sealing effect is better in a thread and sealing gasket mode; the pipe body with all be equipped with the go-between on the pipe cap, two go-between are connected through connecting the rope, connect the rope and even as an organic whole with pipe body and pipe cap, can avoid the loss of pipe cap.

Compared with the prior art, the negative pressure type pharyngeal swab sampler has the following advantages:

(1) the negative pressure type throat swab sampler can provide negative pressure during sampling, and the swab head generates adsorption capacity, so that the adsorption capacity on secretions is stronger, and the sampling amount is larger; being equipped with the bolster simultaneously, avoiding the negative pressure to disappear in the twinkling of an eye, making the negative pressure be the process that disappears gradually, it is long when effective extension negative pressure exists, and then the extension adsorbs for a long time, further increases sample acquisition volume, improves the relevance ratio.

(2) The negative pressure type pharynx swab sampler is characterized in that absorbent cotton is arranged in the hollow inner cavity of the swab rod, the absorbent cotton can absorb liquid entering the swab rod, and the absorbed liquid is prevented from being sucked back to the A section of the swab rod.

(2) The negative pressure type pharynx swab sampler provided by the utility model is simple in structure, convenient to use, low in manufacturing cost and suitable for large-scale popularization and use.
