Description

Cotton swab holder controlled by single finger

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.: CN 111329530A) 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 detection 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 cotton swab holder controlled by a single finger, which comprises an inner shell, a key, a compression spring a, a screw, a shaft, a bearing, a pinion, an incomplete gear, a fixed claw, a movable claw, a compression spring b and a sliding rail.

The key and the compression spring a are arranged in a cavity below the inner shell, wherein one end of the compression spring a is connected with the inner shell, the other end of the compression spring a is connected with the key, and screws are arranged to be connected with two layers of the cavity below the inner shell for assembly convenience; the bearing is arranged on the inner shell and plays the role of supporting the shaft at two ends, and the pinion and the incomplete gear are respectively glued at two ends of the shaft; the static claw and the sliding rail are fixed on the inner shell; the movable claw and the slide rail form a moving pair, and a compression spring b is arranged between the fixed claw and the movable claw; the key and the moving claw are both provided with racks, wherein the racks of the key are matched with the pinion, and the racks of the moving claw are matched with the incomplete gear.

The movement process of the invention is as follows:

when the key is pressed, the key moves forward, the compression spring a is compressed, the key drives the pinion to rotate, and the incomplete gear rotates along with the pinion and the incomplete gear because the pinion and the incomplete gear are coaxial, so that the movable claw is driven to be close to the static claw, and cotton swabs are clamped.

When the key is loosened, the key retreats, the compression spring a is loosened, the key drives the pinion to rotate, and the incomplete gear also rotates along with the pinion and the incomplete gear due to the fact that the pinion and the incomplete gear are coaxial, so that the movable claw is driven to be far away from the static claw, and the cotton swab is loosened.

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

1. the invention has compact structure and stable operation, and adopts the gear and rack to match with the transmission power;

2. the cotton swab is suggested to be worn at the second joint of the forefinger, and the cotton swab can be clamped and released only by simply bending the forefinger.

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 6, a one-finger-operated swab holder includes an inner case 1, a button 21, a compression spring a22, a screw 23, a shaft 31, a bearing 32, a pinion 33, a partial gear 34, a stationary jaw 41, a movable jaw 42, a compression spring b43, and a slide rail 44.

The key 21 and the compression spring a22 are arranged in a cavity below the inner shell 1, wherein one end of the compression spring a22 is connected with the inner shell 1, the other end of the compression spring a22 is connected with the key 21, and in order to facilitate assembly, a screw 23 is arranged to be connected with two layers of the cavity below the inner shell 1; bearings 32 are mounted on the inner case 1 to support the shaft 31 at both ends thereof, and a pinion 33 and an incomplete gear 34 are respectively glued to both ends of the shaft 31; the fixed claw 41 and the slide rail 44 are fixed on the inner shell 1; the movable claw 42 and the slide rail 44 form a moving pair, and a compression spring b43 is arranged between the fixed claw 41 and the movable claw 42; the key 21 and the movable claw 42 are both provided with racks, wherein the rack of the key 21 is matched with the pinion 33, and the rack of the movable claw 42 is matched with the incomplete gear 34.
