Abstract
The utility model relates to a safety head for a vacuum blood collection tube and belongs to the technical field of a medical equipment structure. The safety head for the vacuum blood collection tube comprises a cover body. The cover body is matched and connected with a rubber plug. The inner side wall of the cover body is provided with a convex annular clamping ring. The position on the rubber plug, which is contacted with the annular clamping ring, is provided with a ring-shaped clamping groove matched with the annular clamping ring. The inner wall of the cover body, which is contacted with the rubber plug, is provided with an uneven friction layer. The safety head for the vacuum blood collection tube is reasonable in structural design, is convenient to operate and has high safety. The friction layer is arranged on the inner side wall of the cover body, therefore, a friction coefficient between the cover body and the rubber plug can be increased so that a slipping phenomenon between the cover body and the rubber plug, which is generated when the safety head is opened, is avoided and the cover body is linked with the rubber plug. Moreover, the safety head for the vacuum blood collection tube has simple production process and low cost and is suitable to be popularized and applied.
Description
Technical field
This utility model relates to a kind of vacuum test tube safety head, belongs to technical field of medical device structures.
Background technology
Bayonet type 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; With the butyl rubber plug sealing, butyl rubber plug guarantees that repeated localised puncture is air tight, not desquamation, no reducing substances; The blood that possibly cause of uncapping in order to prevent to test spatters outward; Blood sample did not spatter outward when plug often was furnished with a safety head outward and cover in order to guarantee to take off, but there is following defective in existing safety head: 1, 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 bio-safety hidden danger such as pollution; 2, because the contact surface of safety head and plug is slick, be prone to skidding when therefore uncapping, promptly safety head is removed; And plug is still stayed on the vacuum test tube; This just need tightly pinch safety head when taking, waste time and energy, and uses very inconvenience.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, and is with low cost, can prevent effectively that blood sample from spattering outward, the vacuum test tube safety head easily of uncapping.
This utility model is realized through following technical scheme:
The vacuum test tube safety head; Comprise lid 1; Lid 1 plug 2 that is connected; Lid 1 medial wall is provided with protruding circumferential clasp 3, is provided with the annular slot 4 that matches with the contact position of circumferential clasp 3 on the plug 2, and its special character is that lid 1 and plug 2 contacted inwalls are provided with rough frictional layer 5;
Said frictional layer 5 is the fishing reticulate pattern;
Said frictional layer 5 is twill-like;
Said frictional layer 5 is vertical perpendicular stricture of vagina shape;
Said frictional layer 5 is latticed.
This utility model reasonable in design, easy to operate, safe; Because the lid medial wall is provided with frictional layer, therefore can increase the coefficient of friction between lid and plug, thus the skidding between lid and plug when having avoided uncapping; Make the interlock of lid and plug, in addition, this utility model production technology is simple; Cost is low, suitable applying.
Description of drawings
Fig. 1: the structural representation of this utility model vacuum test tube safety head;
The A-A of Fig. 2: Fig. 1 cuts open structural representation.
The specific embodiment
Provide the specific embodiment of this utility model below with reference to accompanying drawing, be used for the formation of this utility model is done further explanation.
The vacuum test tube safety head of present embodiment; Comprise lid 1; Lid 1 plug 2 that is connected; Lid 1 medial wall is provided with protruding circumferential clasp 3, is provided with the annular slot 4 that matches with the contact position of circumferential clasp 3 on the plug 2, and lid 1 is provided with rough frictional layer 5 with plug 2 contacted inwalls; Frictional layer 5 is the fishing reticulate pattern or is twill-like or is vertical perpendicular stricture of vagina shape or is latticed.
Present embodiment is reasonable in design, and is easy to operate, safe; Because the lid medial wall is provided with frictional layer, therefore can increase the coefficient of friction between lid and plug, thus the skidding between lid and plug when having avoided uncapping; Make the interlock of lid and plug, in addition, this utility model production technology is simple; Cost is low, suitable applying.
