Description

A instrument that is used for in biological safety laboratory to indicate to tie up fast

Technical Field

The invention belongs to the field of biomedical protective devices, and particularly relates to a tool for quickly bundling fingers in a biological safety laboratory.

Background

According to the guiding principle of medical staff AIDS virus occupational exposure protection work in the relevant technical specification of the national health industry, when the medical staff or the laboratory staff of the biological safety laboratory are exposed accidentally, especially when wounds such as needle pricks and blade cuts occur, the following measures are taken: slightly squeezing the wound to squeeze blood from the wound as much as possible, and then washing with soap liquid and flowing water; local compression of the wound is prohibited. However, blood in the human body is flowing, and the blood at the injury is difficult to squeeze out as much as possible by simple squeezing. If the finger blood flow can be quickly slowed or stopped in the event of an accident, great help can be provided for subsequently squeezing out the blood at the injury as much as possible. Infection caused by needle prick, incised wound and the like is reduced to the maximum extent, and meanwhile, the quick hemostasis effect can be achieved.

When the elastically contractible ring 2 is hooped on the working end of the inner cylinder 1, the linear diameter of the elastically contractible ring 2 is larger than the difference between the inner radius of the guide cylinder 6 and the outer radius of the inner cylinder 1.

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

1. the structure is simple, and the use is convenient;

2. can conveniently bind the wound of the finger, and has the effects of slowing down blood circulation and stopping bleeding. Facilitating subsequent disinfection and wound treatment.

Detailed Description

The present invention will be described in further detail with reference to examples for the purpose of facilitating understanding and practice of the invention by those of ordinary skill in the art, and it is to be understood that the present invention has been described in the illustrative embodiments and is not to be construed as limited thereto.

As shown in fig. 1-3, a tool for rapidly bundling fingers in a biosafety laboratory comprises an elastically contractible ring 2, and further comprises an outer barrel 3 and an inner barrel 1 arranged in the outer barrel 3, wherein a sliding groove 5 is formed in the barrel wall of the outer barrel 3, one end of an inner barrel connecting short rod 4 penetrates through the sliding groove 5 from the outer side of the outer barrel 3 to be connected with the inner barrel 1, one end of the inner barrel 1 is a working end, when the inner barrel connecting short rod 4 moves along the sliding groove 5, the working end of the inner barrel 1 is driven to slide into the outer barrel 3 or extend out of the outer barrel 3, when the working end of the inner barrel 1 extends out of the outer barrel 3, the elastically contractible ring 2 is hooped on the working end of the inner barrel 1, and the wire diameter of the elastically contractible ring 2 is larger than the difference value between the.

Under normal conditions, the working end of the inner cylinder 1 extends out of the outer cylinder 3, the working end of the inner cylinder is sleeved with an elastically contractible ring 2 (generally a rubber ring), when fingers are punctured or damaged, the damaged fingers are rapidly inserted into the hollow inner cylinder 1, the inner cylinder is pushed downwards to connect the short rod 4, and the working end of the inner cylinder 1 retracts into the outer cylinder 3. Because the retractable ring 2 of elasticity is hooped and is established on the work of inner tube 1 and the line footpath of the retractable ring 2 of elasticity is greater than the difference of the inner radius of urceolus 3 and the outer radius of inner tube 1, the retractable ring 2 of elasticity is pushed down inner tube 1 by urceolus 3 top, ties up injured finger, plays the effect that slows down the blood circulation and stanch. Facilitating subsequent disinfection and wound treatment.

As a preferred scheme, the outer cylinder 3 comprises an outer cylinder body 7 and a guide cylinder 6, one end of the guide cylinder 6 is flush with one end of the outer cylinder body 7 and is connected with the outer cylinder body through an end face annular plate 8, the guide cylinder 6 is sleeved on the inner cylinder 1, the sliding groove 5 is formed in the outer cylinder body 7, and the working end of the inner cylinder 1 extends out of one end, connected with the end face annular plate 8, of the guide cylinder 6. The length of the guide cylinder 6 is less than that of the inner cylinder 1, and the inner diameter of the guide cylinder 6 is matched with the outer diameter of the inner cylinder 1. When the elastically contractible ring 2 is hooped on the working end of the inner cylinder 1, the line diameter of the elastically contractible ring 2 is larger than the difference value between the inner radius of the guide cylinder 6 and the outer radius of the inner cylinder 1.

Because the length of guide cylinder 6 is less than the length of inner tube 1, the setting of guide cylinder 6 can reduce the frictional force that the outer wall of inner tube 1 produced for the working end withdrawal urceolus 3 of inner tube 1 is more smooth and easy with stretching out urceolus 3, simultaneously, because guide cylinder 6 possesses certain length, can play the guide effect.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
