Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a disposable safety blood taking needle.
Background
The existing blood taking needle has a great potential safety hazard after being used, and because the needle tip is exposed outside the holding body after the needle cap is removed, the existing blood taking needle needs to be carefully packaged in the discarding process to avoid secondary infection caused by injury to the human body again.
Disclosure of Invention
According to the disposable safety blood taking needle, the holding body can be bent after the blood taking needle is used, and the bending part can press the middle part of the needle body in the holding body, so that the needle point can be loosened relative displacement relative to the port of the holding body, and the needle point can be retracted into the holding body.
The utility model provides a disposable safety blood taking needle, includes the body of gripping, needle body and needle cap, be equipped with the horizontal lumen that holds the needle body in the body of gripping, the needle point of needle body wears out from the body left end of gripping, the needle cap parcel needle point just is connected with the body of gripping is removable, the body of gripping includes tearing rib, left casing and right casing, the upper portion of left casing is articulated through the pivot with the upper portion of right casing, and the lower part of left casing is connected through tearing the rib with the lower part of right casing, horizontal lumen crosses left casing and right casing, the tail end and the right casing fixed connection of needle body.
Further, the needle cap and the tearing ribs are integrally formed, and the needle cap is detachably connected with the holding body through the tearing ribs. Grooves for embedding tearing ribs are formed in the lower portions of the left shell and the right shell.
Further, the tail end of the needle body is provided with a limiting block, and a containing cavity matched with the limiting block is arranged in the right shell.
The invention discloses a disposable safety blood taking needle, which creatively makes a holding body into a left shell and a right shell which are mutually hinged, and ensures that the holding body is stably connected by tearing ribs. After the blood taking needle is used, the left shell and the right shell can be easily folded by removing the tearing ribs, the needle body is bent and folded in the folding process, the needle tip of the blood taking needle is retracted into the left shell, and the secondary pollution of the waste blood taking needle is effectively prevented.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings that are required to be used in the description of the embodiments will be briefly described below. It is evident that the drawings described are only some embodiments of the invention, but not all embodiments, and that other designs and drawings can be obtained from these drawings by a person skilled in the art without inventive effort.
FIG. 1 is a schematic view of the disposable safety lancet prior to use;
fig. 2 is a schematic view of the disposable safety lancet after use.
Detailed Description
The conception, specific structure, and technical effects produced by the present invention will be clearly and completely described below with reference to the embodiments and the drawings to fully understand the objects, features, and effects of the present invention. It is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present invention. In addition, all coupling/connection relationships mentioned herein do not refer to direct connection of the components, but rather, refer to the fact that a more optimal coupling structure may be formed by adding or subtracting coupling aids depending on the particular implementation. The technical features in the invention can be interactively combined on the premise of no contradiction and conflict.
As shown in fig. 1 and 2, a disposable safety blood taking needle comprises a holding body 1, a needle body 2 and a needle cap 3, wherein a transverse lumen for accommodating the needle body 2 is arranged in the holding body 1, a needle tip 21 of the needle body 2 penetrates out of the left end of the holding body 1, the needle cap 3 wraps the needle tip 21 and is detachably connected with the holding body 1, the holding body 1 comprises a tearing rib 11, a left shell 12 and a right shell 13, the upper part of the left shell 12 is hinged with the upper part of the right shell 13 through a rotating shaft, the lower part of the left shell 12 is connected with the lower part of the right shell 13 through the tearing rib 11, the transverse lumen penetrates through the left shell 12 and the right shell 13, and the tail end of the needle body 2 is fixedly connected with the right shell 13. When the blood taking needle is used, the needle cap 3 is removed, and the left shell 12 and the right shell 13 are still pulled by the tearing ribs 11, so that the blood taking needle cannot deform, and can normally puncture and take blood. After blood collection is completed, the tearing ribs 11 are further torn off, so that only the hinge point at the upper end is left between the left shell 12 and the right shell 13, and a user can easily bend the holding body 1 along the hinge point, and further drive the left shell 12 and the right shell 13 to bend the needle body 2. In the process of bending the needle body 2, the needle tip 21 of the needle body can move relative to the left shell 12 to retract into the transverse lumen, so that the aim of avoiding possible infection caused by waste blood collection needles is fulfilled.
As a further preferred embodiment, the needle cap 3 is integrally formed with the tear rib 11, and the needle cap 3 is detachably connected to the grip body 1 by the tear rib 11. Since the cap 3 and the tear rib 11 are both members to be removed for the lancet after use, they can be integrally formed and discarded simultaneously after use.
As a further preferred embodiment, the lower parts of the left and right housings 12 and 13 are each provided with a groove into which the tear rib 11 is inserted.
As a further preferable embodiment, a stopper 22 is disposed at the tail end of the needle body 2, and a cavity adapted to the stopper 22 is disposed in the right housing 13.
While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these are intended to be included in the scope of the present invention as defined in the appended claims.
