Abstract
The utility model discloses a kind of vacuum test tube cork puller, left handle and right handles are hinged by the center holding screw, two handles and left caliper and right caliper body junction are provided with the turning joint screw, the left jaw that is fixed on the left caliper end is the opening V shape, right jaw is a brake holding formula sleeve, brake holding formula sleeve is divided into movable chuck and fixed chuck two parts, fixed chuck is fixed in the right caliper body end, the movable chuck driving built-in stage clip interior with being installed in right caliper body is connected, and is provided with between the caliper of the left and right sides and can makes the automatically reset spring that rises of left and right sides jaw.The utility model only needs firmly just can pull up soft rubber ball gently, in the time of can not causing drawing the cork because of overexerting blood be taken out of, pollutes staff's hand, thereby has prevented the cross-infection that causes in the work; And simple in structure, easy to operate, quick, improved work efficiency.
Description
Technical field
The utility model relates to a kind of cork puller, is specially a kind of vacuum test tube cork puller.
Background technology
Each medical institutions' blood sampling at present mostly adopts vacuum test tube to replace syringe, is a kind of advanced person's requisite blood sampling censorship vessel.Negative pressure sucks blood in this heparin tube utilization pipe, soft rubber ball must be pulled out during detection, and the staff uses hand-lifting without exception at present, but because heparin tube is with negative pressure always, want the bigger strength of both hands when drawing the cork, operating difficulties, and blood is arranged in the pipe, easily blood is taken out of when drawing the cork, pollute staff's hand, need constantly to wash one's hands, work is inconvenient, inefficiency, and be easy to cross-infection.CN03227376.2 discloses a kind of vacuum test tube cork puller, its left jaw is the opening V shape, and right jaw is a brake holding formula sleeve, and left and right sides caliper head is respectively equipped with vertical pin, be respectively equipped with on the jaw of the left and right sides with left and right sides caliper on the cooresponding pin-and-hole of vertical pin, by locking pin the two is locked.This structure is still complicated, and is still not too convenient during operation.
The utility model content
The purpose of this utility model is to provide a kind of easy to operate, high efficiency, can stops the vacuum test tube cork puller of cross-infection
The technical solution of the utility model is: left handle and right handles are hinged by the center holding screw, two handles and left caliper and right caliper body junction are provided with the turning joint screw, the left jaw that is fixed on the left caliper end is the opening V shape, right jaw is a brake holding formula sleeve, brake holding formula sleeve is divided into movable chuck and fixed chuck two parts, fixed chuck is fixed in the right caliper body end, the movable chuck driving built-in stage clip interior with being installed in right caliper body is connected, and is provided with between the caliper of the left and right sides and can makes the automatically reset spring that rises of left and right sides jaw.
Described left and right sides caliper brachium is greater than left and right sides jaw brachium.
Described movable chuck accounts for 2/5 of brake holding formula sleeve, and fixed chuck accounts for 3/5 of brake holding formula sleeve.
The size of the left and right sides of the present utility model jaw has different size, applicable to the heparin tube of various different sizes.
The utility model only needs firmly just can pull up soft rubber ball gently, in the time of can not causing drawing the cork blood be taken out of, polluted staff's hand, thereby prevented the cross-infection that causes in the work because of overexerting, and simple in structure, easy to operate, quick, improved work efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Embodiment 1:
In conjunction with the accompanying drawings: left handle 1 and right handles 2 are hinged by center holding screw 9, two handles and left caliper 3 and right caliper body 4 junctions are provided with turning joint screw 10, the left jaw 5 that is fixed on the left caliper end is the opening V shape, right jaw becomes brake holding formula tube-in-tube structure, be divided into movable chuck 6-1 and fixed chuck 6-2 two parts, fixed chuck 6-2 is fixed in the right caliper body end, account for 3/5 of brake holding formula sleeve, movable chuck 6-1 accounts for 2/5 of brake holding formula sleeve, the movable chuck driving built-in stage clip 7 interior with being installed in right caliper body is connected, and is provided with between the caliper of the left and right sides and can makes the automatically reset spring 8 that rises of left and right sides jaw.
During use heparin tube is inserted in the brake holding formula sleeve, the soft rubber ball place of the corresponding heparin tube of opening V shape left side jaw, the left and right sides handle of holding with a firm grip gently, the turning joint screw makes left and right sides caliper around its center holding screw rotation, the movable chuck of right jaw is held heparin tube tightly by the built-in stage clip of driving, and left and right sides caliper separates simultaneously, because the caliper brachium is greater than the jaw brachium, according to lever principle, only need firmly just can pull up gently the soft rubber ball of heparin tube.Behind the bung off, the spring i.e. bounce-back after release handle of rising between the caliper of the left and right sides is opened two handles, causes left and right sides caliper around its center holding screw contrarotation, makes left and right sides jaw automatically reset.
Claims (3)
