Abstract
The utility model relates to the technical filed of medical instruments, in particular to a safety head cover for a vacuum blood collecting tube. The safety head cover comprises a cover body (2), and the cover body is connected with a rubber plug in a matching way; the safety head cover is characterized in that the inner side wall of the cover body (2)is provided with a clamp ring (3) and an annular rack (4); and a clamping groove (6) and an annular toothspace (7) are matched and arranged at the contact parts of a rubber plug body (5) with the clamp ring (3) and the annular rack (4). The safety head cover has the benefits of simple structure, convenient operation and high safety; the inner side wall of the safety head cover is provided with the clamp ring and the annular rack, therefore, a test tube and the rubber plug are tightly combined with the safety head cover after entering the safety head cover, and are not easy to drop, thus leading to an effect of double protection; in addition, the safety head cover has simple production technique and low cost, and is suitable for popularization and application.
Description
[technical field]
This utility model relates to a kind of armarium technical field, particularly a kind of safety head that is used for vacuum test tube.
[background technology]
The vacuum test tube safety head is the important component part of vacuum test tube, the material of vacuum test tube is glass or plastics, test tube is quantitative evacuation after special handling, seal with butyl rubber plug, butyl rubber bung guarantees repeated localised puncture air tight, not desquamation, no reducing substances, the blood that may cause of uncapping in order to prevent to test spatters outward, and blood sample did not spatter outward when plug often was furnished with a plastic safety skull outward and cover in order to guarantee to take off.But existing safety head combines defective tightness with plug, exists vacuum test tube to occur in use that safety head separates with plug that the blood sample that causes in the blood taking tube spatters outward and the hidden danger of bio-safety such as pollution.
[summary of the invention]
Task of the present utility model overcomes the deficiencies in the prior art exactly, and a kind of vacuum test tube safety head is provided, and can guarantee combining closely of safety head and plug, and simple in structure, is easy to promote.
This utility model adopts following technical proposals: a kind of vacuum test tube safety head is provided, comprise lid 2, the described lid plug that is connected, the medial wall of described lid 2 is provided with snap ring 3 and annular rack 4, is provided with draw-in groove 6 and the ring slot 7 that matches with the contact position of snap ring 3 and annular rack 4 on described rubber plug body 5.
Described snap ring 3 and annular rack 4 are positioned at the porch that plug enters lid 2.
Be provided with equally distributed projection 1 in the medial wall of described lid 2 ends, described projection 1 is positioned at same plane ring formation shape.
The beneficial effects of the utility model: simple in structure, easy to operate and safe, in the medial wall of safety head snap ring and annular rack are set, make that entering the back at test tube and plug combines with the tight of safety head, difficult drop-off, and have the effect of duplicate protection; In addition, this utility model production technology is simple, and cost is low, suitable applying.
