Abstract

The invention designs a novel pharynx swab collecting mouthpiece which mainly comprises a front positioning and protecting baffle, a tooth fixing module, a rear tongue pressing module and a pharynx swab collecting channel. The pharynx swab collecting device is simple in structure and convenient to use, when the pharynx swab is collected, the head of a person to be collected is fixed through the special fixing device, the pharynx sampling part of the person to be collected is fixed and fully exposed through the tooth fixing module and the rear tongue pressing module, medical staff complete the sampling process through the pharynx swab collecting channel, meanwhile, the front protective baffle effectively prevents pollution of pharynx droplets to the medical staff, and meanwhile, the pharynx swab collecting device can protect the oral cavity of the person to be collected.

Description

Novel pharynx swab gathers seaming ware

Technical Field

This patent design belongs to the medical instrument field, and more specifically the design is a novel pharynx swab gathers seaming ware that says so.

Background

For the diagnosis of a wide range of respiratory infectious diseases, pharyngeal swab sampling in modern medicine is a routine collection means. However, because the collection part of the pharyngeal swab is positioned on the pharyngeal back wall of the human body, due to the characteristics of the structure of the human body, for the collection at the position, firstly, the oral cavity needs to be opened by a person to be collected, so that the person can make an o sound, and meanwhile, the medical care personnel need to press the tongue body by using a tongue spatula to smoothly complete the collection. In the process, the person to be collected may have a severe pharyngeal reflex reaction, which causes reflex movement of the head, and thus may cause damage to the tissue structure, which causes physical and psychological damage to the person to be collected. It is very necessary to design a novel mouth piece for maintaining the shape and position of the oral cavity and the pharyngeal cavity of a person to be collected in the sampling process of the pharyngeal swab.

Disclosure of Invention

The purpose of this patent is exactly to present stage medical personnel pharynx swab collection in-process, is gathered the fixed of people's oral cavity, pharynx chamber form and position and the optimization of pharynx swab collection process. The invention has simple structure and convenient use, ensures that medical care personnel can successfully finish the sampling action of the throat swab, and simultaneously plays a good role in protecting the oral cavity and the pharyngeal organs of the collected person.

The design content of the invention is as follows:

the utility model provides a novel pharynx swab gathers seaming ware which characterized in that, this seaming ware comprises anterior location and guard flap 1, tooth fixed module 2, rear portion tongue pressing module 3 and 4 four bibliographic categories of pharynx swab collection channel parts.

The front positioning and protecting baffle plays a role in fixing the mouthpiece and preventing the collected human pharyngeal droplet from polluting medical care personnel in the pharynx swab collecting process.

The tooth fixing module is tightly attached to the oral cavity teeth of the collected person in the pharynx swab collecting process, so that the position and the shape of the internal structure of the oral cavity and the pharynx cavity are kept unchanged in the sampling process of the collected person.

The rear tongue depressing module plays a role of a tongue depressing plate on the tongue body of a person to be collected in the collecting process of the throat swab, and ensures that sampling is not unsuccessful due to overhigh tongue position and/or falling of the tongue body during collecting.

The pharynx swab collecting channel is a cavity part in the middle of the mouth piece, and the collection and the smooth taking-out path of the pharynx swab in the pharynx are guaranteed.

The specific implementation mode is as follows:

the following description is only an example of the present invention and does not limit the scope of the present invention.

Example (b): referring to fig. 1, the novel pharynx swab collecting bite-piece comprises a front positioning and protecting baffle, a tooth fixing module, a rear tongue pressing module and a pharynx swab collecting channel.

During the collection process of the throat swab, the functions of each part are as follows:

The tooth fixing module is tightly attached to the oral cavity teeth of the collected person in the pharynx swab collecting process, so that the position and the shape of the internal structure of the oral cavity and the pharynx cavity are kept unchanged in the sampling process of the collected person. The rear tongue depressing module plays a role of a tongue depressing plate on the tongue body of a person to be collected in the collecting process of the throat swab, and ensures that sampling is not unsuccessful due to overhigh tongue position and/or falling of the tongue body during collecting.

Claims

1. The utility model provides a novel pharynx swab gathers seaming ware which characterized in that, this seaming ware comprises anterior location and guard flap (1), tooth fixed module (2), rear portion tongue pressing module (3) and pharynx swab collection channel (4) four bibliographic categories branch.

2. The pharyngeal swab collecting mouthpiece of claim 1, wherein the front positioning and protective shield serves to secure the mouthpiece and prevent contamination of medical personnel by pharyngeal spray of the person being collected during the pharyngeal swab collection process. The length and width ranges of the protective baffle are 130mm to 165mm and 130mm to 165mm respectively, and the offset of the central opening of the collecting channel is 0% to 30% of single direction.

3. The pharynx swab collecting mouthpiece as claimed in claim 1, wherein the teeth fixing module is closely attached to the teeth of the mouth of the person during the pharynx swab collecting process, so as to ensure that the position and shape of the internal structure of the mouth and the pharynx are kept unchanged during the sampling process.
