Abstract
What the utility model was related to is bayonet type Anti-drop transfusion utensil, including bayonet set and bayonet part, the bayonet set is hollow circle tube structure, since flexible diaphragm is rolled into hollow cylinder shape, diaphragm both sides are provided with attachment device, for being interconnected diaphragm both sides, cylinder sides are provided with symmetrical bayonet channel, the bayonet channel penetrates outer surface in diaphragm, and the bayonet channel side is considered as inverted "L" shape, and the terminal in bayonet channel is a circular hole；Bayonet part is the cylindrical structure that there is through-hole in centre, and the through-hole diameter and transfusion needle form interference fit, and bayonet part upper end is provided with symmetrical two protrusions, the Circularhole diameter formation interference fit of projection diameter and bayonet tunnel end points.The application Fast Installation, sound construction, even if still will not fall off in the case where external force is pullled.
Description
Technical field
The utility model is related to be bayonet type Anti-drop transfusion utensil.
Background technology
Anti-drop transfusion utensil is very useful in infusion, for preventing in infusion process because external force caused by accident is pullled,
Infusion apparatus is caused to be extracted from infusion bag.Also have been devised by various Anti-drop transfusion utensils at present.The application provides a kind of
The Anti-drop transfusion utensil of Novel structure, to reach Fast Installation, sound construction, even if what still be will not fall off in the case where external force is pullled is anti-
De- infusion apparatus.
Utility model content
In view of this, to solve the above-mentioned problems, the utility model provides a kind of bayonet type Anti-drop transfusion utensil.
Bayonet type Anti-drop transfusion utensil, including bayonet set and bayonet part, the bayonet set are hollow circle tube structures, due to tool
Flexible diaphragm is rolled into hollow cylinder shape, and diaphragm both sides are provided with attachment device, for diaphragm both sides to be interconnected,
Cylinder sides are provided with symmetrical bayonet channel, the bayonet channel penetrates outer surface in diaphragm, the bayonet channel side
It is considered as inverted "L" shape, the terminal in bayonet channel is a circular hole；Bayonet part is the cylindrical structure that there is through-hole in centre, the through-hole
Diameter and transfusion needle form interference fit, and bayonet part upper end is provided with symmetrical two protrusions, and projection diameter and bayonet channel are whole
The Circularhole diameter of point forms interference fit.
Further, the attachment device side of diaphragm both sides is vertical several single-row through-holes, the other side be position and
Through-hole is corresponding, vertical several single-row protrusions.
Further, bayonet part intermediate throughholes inner surface is provided with screw thread, and transfusion needle outer surface is provided with and table in through-hole
The matched screw thread in face.
In use, being first wrapped in diaphragm upper semisection on the port of infusion bag bottom, both sides attachment device is mutually fastened.
Then transfusion needle is inserted into be formed in the through-hole of bayonet part and is interference fitted, then by two protrusions of bayonet part upper end along cylinder side
Face bayonet channel rotates after being inserted into bottom, then the two of bayonet part upper end protrusion is inserted into the circular hole of bayonet tunnel end points, due to film
There is piece elasticity, protrusion and circular hole to be formed after interference fit, and the diaphragm of circular has intensifying force to protrusion.Even if having at this time
Slight external force pulls transfusion needle, and two protrusions of bayonet part upper end still will not be slipped from bayonet channel.Unless external force is
Violence directly extracts transfusion needle from bayonet part, causes the disintegration of infusion apparatus, then such situation does not consider it in the application
It is interior.

Specific implementation mode
Bayonet type Anti-drop transfusion utensil, including bayonet set 1 and bayonet part 3, the bayonet set 1 is hollow circle tube structure, by
It is rolled into hollow cylinder shape in flexible diaphragm, diaphragm both sides are provided with attachment device 6, and 6 side of attachment device is vertical single
Several through-holes 61 of row, the other side is position and through-hole 61 is corresponding, vertical several single-row second protrusions 62, for will
Diaphragm both sides 6 are interconnected.Cylinder sides are provided with symmetrical bayonet channel 2, the bayonet channel 2 penetrates in diaphragm
Outer surface, 2 side view of bayonet channel are inverted "L" shape, and the terminal in bayonet channel 2 is a circular hole 21；Bayonet part 3 is centre
There are the cylindrical structure of through-hole, the through-hole diameter and transfusion needle 4 to form interference fit, 3 upper end of bayonet part is provided with symmetrically
21 diameter of circular hole of two the first protrusions 31, the first raised 31 diameters and 2 terminal of bayonet channel forms interference fit.
In use, first diaphragm upper semisection is wrapped on the port 5 of infusion bag bottom, both sides attachment device 6 is mutually interlocked
Tightly.Then transfusion needle 4 is inserted into be formed in the through-hole of bayonet part 3 and is interference fitted, then by two protrusions 31 of 3 upper end of bayonet part
Along 1 side bayonet channel 2 of cylinder be inserted into bottom after rotate, then two first of 3 upper end of bayonet part protrusions 31 are inserted into bayonet channel 2
The circular hole 21 of terminal forms interference fit.
