Abstract

The invention provides a cotton swab holder based on a torsion spring. The cotton swab can be loosened by clamping the inner ring of the ring and the clamping plate of the outer ring of the ring with fingers; the fingers are loosened, and the cotton swab can be clamped tightly due to the elasticity of the torsion spring. The cotton swab clamping and releasing device is simple in structure and convenient to operate, and can clamp and release a cotton swab by using the left finger and the right finger to clamp and release the cotton swab.

Description

Cotton swab holder based on torsion spring

Technical Field

The invention relates to the technical field of sampling of pharynx wipers, in particular to a cotton swab clamping device for sampling of pharynx wipers.

Background

New crown pneumonia is the acute respiratory infectious disease that is aroused by novel coronavirus infection, medical personnel carry out the pharynx swab and gather the sample, the cotton swab stick is lighter and slender, take to hold between the fingers special needs to pay attention in order to avoid dropping, drop the easy extravagant cotton swab stick before gathering, and drop after gathering then cause the infection risk easily, the pharynx swab sampling number of times during the epidemic situation is many simultaneously, it is great to medical personnel's physical demands, and through forefinger, thumb and middle finger are long-time, it holds between the fingers the cotton swab stick to take many times, cause the hand tired out very easily, the cotton swab stick risk that drops has more increased.

To change this situation, Chinese patent (patent No.: CN111329530A) invented a swab holder for sampling epidemic pharyngeal swab. This patent only alternates the non-sampling end of cotton swab through pointing the sleeve cover on the finger in the excellent sleeve cover, and in the in-service use, the cotton swab needs take off after using to settle and change the new cotton swab, makes the sample rate descend. In addition, whether the cotton swab is matched in the rod sleeve and is inserted stably or not needs to be considered when the new cotton swab is replaced, when the diameter of the cotton swab rod is larger than that of the rod sleeve, the rod sleeve is inconvenient to insert, and when the diameter of the cotton swab rod is smaller than that of the rod sleeve, the cotton swab is easy to fall off, so that the infection risk is caused, and the pharynx of a patient receiving and detecting can be injured.

Disclosure of Invention

The invention aims to solve the problems of complex operation and difficulty in replacing cotton swabs in the prior art, and provides a cotton swab holder which is convenient to operate, stable and reliable in movement, convenient to take and use cotton swabs and reliable in clamping.

In order to solve the technical problem, the invention provides a torsion spring-based cotton swab holder which comprises a ring inner ring, a bearing, a washer, a ring outer ring, a screw, a nut and a torsion spring.

The ring inner ring and the ring outer ring are both provided with handles, and two extending ends of the torsion spring are respectively contacted with the handles of the ring inner ring and the ring outer ring. A bulge is arranged at the clamping position of the outer ring of the ring, so that the cotton swab is prevented from being misplaced.

The movement process of the invention is as follows: the cotton swab can be loosened by clamping the inner ring of the ring and the clamping plate of the outer ring of the ring with fingers; the fingers are loosened, and the cotton swab can be clamped tightly due to the elasticity of the torsion spring.

Compared with the prior art, the invention has the following beneficial effects:

1. the invention has simple structure and convenient operation;

2. the cotton swab is suggested to be worn at the forefinger, and the cotton swab can be clamped and released by clamping and releasing the left finger and the right finger.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 3, a cotton swab holder based on a torsion spring comprises a ring inner ring 1, a bearing 2, a washer 3, a ring outer ring 4, a screw 5, a nut 6 and a torsion spring 7.

The ring inner ring 1 is matched with the inner ring of the bearing 2, the ring outer ring 4 is matched with the outer ring of the bearing 2, the gasket 3 is clamped between the two bearings 2, the torsion spring 7 is fixed through the screw 5 and the nut 6, the ring inner ring 1 and the ring outer ring 4 are both provided with handles, and two extending ends of the torsion spring 7 are respectively contacted with the handles of the ring inner ring 1 and the ring outer ring 4. A bulge is arranged at the clamping position of the outer ring 4 of the ring, so that the cotton swab is prevented from being misplaced.

The movement process of the invention is as follows:

the cotton swab can be loosened by clamping the clamping plates of the inner ring 1 and the outer ring 4 of the finger ring with fingers; the fingers are loosened, and the cotton swab can be clamped tightly due to the elasticity of the torsion spring 7.

The above embodiments are merely illustrative of the present invention and not restrictive, and it should be understood by those skilled in the art that the present invention may be modified and equivalents may be substituted for some or all of the features of the embodiments, and any modifications, equivalents, improvements and the like within the spirit and principle of the present invention should be included in the protection scope of the present invention.
