Abstract
The utility model relates to a novel infusion apparatus puncturing needle head, belonging to the technical field of medical apparatuses, which is an improvement based on the existing infusion apparatus puncturing needle head. The utility model is characterized in that a rectangular gap (3) communicated with a liquid passage in a needle body (1) is axially arranged on the needle body (1) above a needle stand (2), the upper end of the rectangular gap (3) is communicated with a liquid outlet (4) on the needle body (1), and distance from the lower end of the rectangular gap (3) to the needle stand (2) is equal to the depth of a rubber plug on an infusion bottle. The utility model has the advantages that the structure is simple, the use is convenient, the residual liquid in the infusion bottle can be fully output through the rectangular gap on the needle body when the liquid level is lower than the liquid outlet on the needle body, and thereby the dosage applied to a patient is ensured and the liquid wastage is avoided.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of novel transfusion device piercing needle.
Background technology
At present, clinical when giving patient infusion, used transfusion device piercing needle inserts in the infusion bottle, and when liquid plane in the infusion bottle was lower than the piercing needle height of insertion, just no longer output of liquid must be changed infusion bottle or stop transfusion in the bottle, causes liquid waste; Sometimes for fear of liquid waste, piercing needle is extracted a segment distance downwards, though do not waste medicinal liquid, piercing needle is exposed to airborne part-time and has grown easily and polluted.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and medicinal liquid in the infusion bottle all can be lost when transfusion, can not cause the residual novel transfusion device piercing needle of medicinal liquid.
The purpose of this utility model is achieved in that this novel transfusion device piercing needle is to improve to form on the basis of existing transfusion device piercing needle, the needle body that it is characterized in that the needle stand top axially has the rectangular slot that communicates with fluid passage in the needle body, rectangular slot upper end communicates with liquid outlet above the needle body, and the lower end is identical with rubber stopper thickness on the infusion bottle to the distance between the needle stand.
Advantage of the present utility model: simple in structure, easy to use, when the liquid plane was lower than liquid outlet above the needle body, the residual liquid in the infusion bottle can all be exported by the rectangular slot above the needle body, guaranteed patient's dosage, avoided liquid waste.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this novel transfusion device piercing needle is to improve to form on the basis of existing transfusion device piercing needle, the needle body 1 that it is characterized in that needle stand 2 tops axially has the rectangular slot 3 that communicates with fluid passage in the needle body 1, liquid outlet 4 above rectangular slot 3 upper ends and the needle body 1 communicates, and the lower end is identical with rubber stopper thickness on the infusion bottle to the distance between the needle stand 2.
Claims (1)
1. novel transfusion device piercing needle, the needle body (1) that it is characterized in that needle stand (2) top axially has the rectangular slot (3) that communicates with the interior fluid passage of needle body (1), rectangular slot (3) upper end communicates with liquid outlet (4) above the needle body (1), and the distance that the lower end is arrived between the needle stand (2) is identical with rubber stopper thickness on the infusion bottle.
