Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a prevent infecting pharynx swab, including swab 1, swab 1 includes head 10 and pole portion 11, this prevent infecting pharynx swab is still including supporting skeleton 2, resilience skeleton 3 and film 4, supporting skeleton 2 includes first lantern ring 20 and many spinal branchs vaulting pole 21, resilience skeleton 3 includes second lantern ring 30 and many resilience poles 31, pole portion 11 is located to first lantern ring 20 slidable cover, pole portion 11 is located to second lantern ring 30 fixed cover, many spinal branchs vaulting pole 21 correspond the setting with many resilience poles 31, the equal fixed connection in first lantern ring 20 of one end of many spinal branchs vaulting pole 31, the equal fixed connection in second lantern ring 30 of one end of many resilience poles 31, other end fixed connection is on spinal branchs vaulting pole 21, film 4 glues and connects many spinal branchs vaulting pole 21 on locating many spinal branchs vaulting pole 21.

Specifically, in the present invention, the second collar 30 is adhered to the rod portion 11 of the swab 1 by glue, so that the position of the second collar 30 is fixed, and the manufacturing cost thereof is reduced to a certain extent, in a normal state, the resilient rod 31 and the support rod 21 are both adhered to the rod portion 11, the length of the resilient rod 31 is smaller than that of the support rod 21, one end of the resilient rod 31, which is far away from the second collar 30, is connected to one side of the support rod 21, which is far away from the first collar 20, and the middle portion of the resilient rod 21 is bent toward the rod portion 11, so as to ensure that when the first collar 20 moves, one end of the resilient rod 31, which is far away from the second collar 30, is bent outward, so that the support rod 21 is stretched outward. The doctor only needs to tear first lantern ring 20 with external force and makes it slide, can order about rebound rod 31 crooked to make bracing piece 21 be being driven and keeping away from the swing of pole portion 11, and then strut and glue film 4 on locating bracing piece 21, make it become umbrella structure, can block the droplet that the patient harshes in the mouth when the doctor carries out the sample of pharynx swab, convenient to use, and can effectually reduce the risk that the doctor received the infection.

Furthermore, the film 4 is made of transparent material, so that the physician can conveniently and clearly observe the position of the head 10 of the swab 1 while using the anti-infection swab to block the spray, thereby ensuring the success of sampling.

Further, bracing piece 21 and rebound rod 31 are the elasticity plastic material, adopt the plastic material can reduce the cost of manufacture, and because it has elasticity, can not cause bracing piece 21 or rebound rod 31 to break because of the deformation degree is too big, and carry out fixed connection through the hot melt between rebound rod 31 and the bracing piece 21. In the embodiment of the present invention, the resilient rod 31 and the support rod 21 are both made of TPR material.

Further, the first collar 20 is further provided with grooves 200 at both sides thereof for being easily broken by a human hand, in one embodiment of the present invention, the support rod 21 and the resilient rod 31 are both disposed toward the head, the second collar 30 is disposed near the head 10, and the first collar 20 is disposed away from the head 10. When in use, the two fingers are used for clamping the grooves 200 at the two sides of the first collar 20, and the other finger is used for propping against the tail end of the swab 1, so that the first collar 20 is far away from the second collar 30 to move, and the thin film 4 can be spread to be umbrella-shaped. In another embodiment of the present invention, the support rod 21 and the resilient rod 31 can be reversed to drive the first collar 20 to move toward the second collar 30, so as to expand the membrane 4.

Further, since the physician needs to stir the swab when sampling the oral cavity of the patient, and the tip of the front end of the support rod 21 may possibly snag on the face of the patient, in the embodiment of the present invention, the end of the support rod 21 away from the first collar 20 is further provided with a stab-resistant ball 210 for preventing the support rod 21 from stabbing on the face of the patient.

Further, to prevent the swab 1 from accidentally penetrating too far into the patient's throat, the distance between the bottom of the second collar 30 and the head 10 of the swab 1 is 12 cm.

Furthermore, the support rod 21 has a first state of completely wrapping the head of the swab 1 and a second state of being spread to form an umbrella shape, and when the support rod 21 is in the second state, it is in an arc-shaped structure, and a connecting line between two ends of the support rod 21 forms an included angle of 50 degrees with the rod portion 11, and since a distance between the bottom of the second collar 30 and the head 10 of the swab 1 is 12 cm, a length of the support rod 21 exceeds 12 cm.

In the embodiment of the present invention, the length of the support rod 21 is defined as 15 cm, and the length of the rebound rod 31 is defined as 12 cm; when the film 4 is unfolded into an umbrella shape and completely blocks the front face of the mouth of a patient, and the supporting rod 21 and the rod part 11 form an included angle of 50 degrees, the moving stroke of the first collar 20 can be effectively shortened, the rebound rod 31 is prevented from being broken due to excessive bending, the axial force borne by the second collar 30 is reduced, and the shape design of the face of the human body is better fitted. Wherein, when the head 10 of swab 1 stretched into the patient oral cavity, support skeleton 2 all was "X" form with resilience skeleton 3 and covers patient's face, and patient's nose and chin position hug closely film 4, in order to prevent the nose contact of resilience skeleton 3 with the patient, the middle part of crooked resilience pole 31 this moment can with the facial butt around the patient oral cavity, when head 10 excessively stretched into patient's pharynx because of unexpected factor, can play the cushioning effect, the head 10 that blocks swab 1 continues deep throat, cause patient's pharynx to be injured. When the swab 1 collects the pharyngeal sample of the patient, after the physician extends the head 10 of the swab 1 into the culture medium to preserve the sample, the external force applied to the first collar 20 can be removed, and the support rod 21 is directly returned to the first state from the second state, and the head 10 of the swab 1 is wrapped, so that the risk of secondary infection caused by the waste swab is reduced.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application.
