Abstract
The utility model relates to a safety helmet for blood sampling tube, especially a helmet for vacuum blood sampling. The helmet for vacuum blood sampling includes: an upper lid with hollow cavity and a lower lid with hollow cavity. The bottom edge of the outer wall of the upper lid is provided with an external boss, the bottom edge of the inner wall of the upper lid is provided with an internal channel, the top edge of the outer wall of the lower lid is provided with an external hook matching the internal channel. The external hook and the internal channel are of interference fit. The inner wall of the lower lid is provided with a convex neck. The utility model has the advantages of no internal boss and no need of rotation operation by both hands. The utilization of the external boss makes no need to apply force from the bottom but from the external boss with a single hand. The interference fit between the external hook and the internal channel can guarantee tight contact between the upper lid and the lower lid, so that the rubber plug can not easily drop from the cavity between the upper lid and the lower lid. The model is safe and easy to push and pull out rubber plug and lid.
Description
Technical field
This utility model relates to the safety helmet that a kind of blood taking tube is used, the effective safety helmet of especially a kind of vacuum blood collection.
Background technology
Early stage blood taking tube technology is more backward, and plug separates easily with block, and CN03224217.4 has done suitable improvement to early stage blood taking tube.
Operator such as nurse or doctor often contact blood taking tube and blood taking tube safety helmet, and the basic demand that the design of blood taking tube safety helmet should be satisfied is to prevent that as far as possible nurse or doctor's hands is by blood contamination.Medical personnel are because the another hands need be held other medicine or utensil; usually more need one-handed performance to extract the plug or the block of vacuum test tube; the deficiency of CN03224217.4 need to be singlehanded bottom, outer from the blood taking tube safety helmet to put forth effort to eject the blood taking tube safety helmet; its security protection is imperfection also, and blood still contacts medical personnel easily.So CN03224217.4 only is fit to bimanualness.And one-handed performance, difficult contact medical personnel's vacuum test tube is more welcome, but the safety helmet of CN03224217.4 relies on flange to contact with the tube wall of vacuum test tube, usually need the both hands rotation to extract plug and block, if must one-handed performance, then need to support to push open and open plug and block from the edge, bottom of blood taking tube safety helmet, because push away along supporting from the block bottom sides, still cause blood and medical personnel's Body contact easily, still have potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of bimanualness that both had been fit to, and is particularly suitable for the effective safety helmet of vacuum blood collection of one-handed performance again.
The technical solution of the utility model is:
The effective safety helmet of vacuum blood collection, wherein: the effective safety helmet of this vacuum blood collection comprises that inner chamber is that the loam cake and the inner chamber of hollow is the lower cover of hollow, and the outer wall lower edge of loam cake is provided with outer lug boss, and the inwall lower edge of loam cake is provided with internal channel; The outer wall upper edge of lower cover is provided with the outer hook with the internal channel coupling, outer hook and internal channel interference fit, and the inwall of lower cover also is provided with protruding neck.
Advantage of the present utility model is:
Without inward flange, do not need the both hands rotary manipulation.And the employing outer lug boss does not just need from the bottom to put forth effort, and can change one-handed performance into to put forth effort from outer lug boss, and outer hook and internal channel interference fit can guarantee loam cake and lower cover firm locking, and plug is not easy to come off from the inner chamber of loam cake and lower cover.Safety is good, very pushes away easily again and extracts plug and block.

The specific embodiment
Embodiment 1, the effective safety helmet of vacuum blood collection, wherein: the effective safety helmet of this vacuum blood collection comprises that inner chamber is the loam cake 1 of hollow and the lower cover 4 that inner chamber is hollow, and the outer wall lower edge of loam cake 1 is provided with outer lug boss 2, and the inwall lower edge of loam cake 1 is provided with internal channel 3; The outer wall upper edge of lower cover 4 is provided with the outer hook 5 with internal channel 3 couplings, outer hook 5 and internal channel 3 interference fit, and the inwall of lower cover 4 also is provided with protruding neck 6.
Plug is placed in the inner chamber of loam cake 1 and lower cover 4 earlier.Reuse equipment impels outer hook 5 and internal channel 3 interference fit, can guarantee loam cake 1 and lower cover 4 firm lockings.Plug is not easy to come off from the inner chamber of loam cake 1 and lower cover 4.Safety is good.
