Furthermore, a spring which is suitable for enabling the clamping part to be in an open state when the clamping part is static is arranged between the first clamping piece and the second clamping piece.
In yet another aspect, the present invention further provides a venous indwelling needle assembly comprising:
the intravenous indwelling needle comprises an indwelling needle seat, a hose, a heparin cap and a limiting mechanism for the intravenous indwelling needle, wherein the limiting mechanism is suitable for limiting the hose.
The beneficial effects of the utility model are that, the utility model discloses a stop gear and vein indwelling needle subassembly for needle are kept somewhere to the vein can carry on spacingly to the hose to prevent that the hose from dropping.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic structural view of the venous indwelling needle of the present invention;
fig. 2 is a schematic structural view of the holding member of the present invention;
fig. 3 is a partial schematic view of the clamp of the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the present invention provides a vein indwelling needle assembly, comprising: the device comprises an indwelling needle base 1 and a hose 2, wherein one end of the hose 2 is connected with the indwelling needle base 1, and the other end of the hose is connected with a heparin cap 3; the flexible pipe 2 at one side of the heparin cap 3 is provided with an elastic connecting piece 4, and is connected with a clamping piece 6 through a limit connecting wire 5 connected with the elastic connecting piece 4; the holder includes: a grip portion 601 and a locking portion, the grip portion 601 being adapted to fix the hose 2 by gripping the laundry 7; the lock catch part is suitable for locking the clamping part 601 and is connected with the elastic connecting piece 4 through the limiting connecting line 5; the locked state of the grip 601 is released by unlocking the locker, so that the grip 601 is separated from the laundry 7.
The garment 7 may be a cuff position of a patient garment.
Wherein the elastic connecting piece is suitable for being made of elastic materials; the limiting connecting line 5 is 2-4cm, is not suitable for overlong, and has a length of 2-4cm, so that a certain moving distance is formed between the venous indwelling needle and clothes, the venous indwelling needle is prevented from being pulled out when the venous indwelling needle moves slightly in the clothes or the insertion position of the venous indwelling needle, and a good limiting effect can be achieved on the venous indwelling needle.
The holder includes: a first clamping piece 602 and a second clamping piece 603, wherein the first clamping piece and the second clamping piece are crossed and hinged through a hinge shaft 604; the front ends of the first clamping piece and the second clamping piece are used as clamping parts 601, and the rear ends are provided with the locking parts; the lock catch part comprises a lock catch rod 605 connected with the limiting connecting line 5, one end of the lock catch rod 605 is rotatably connected to the rear end of the first clamping piece 602, the other end of the lock catch rod 605 is a free end and is buckled at the rear end of the second clamping piece 603, the lock catch rod 605 and the locking surface of the second clamping piece 603 are in damping fit, the damping surface 603a of the second clamping piece 603 and the damping surface 605a of the lock catch rod 605 enable the lock catch part to have certain damping, the clamping effect is improved, and the lock catch part is suitable for manual unlocking.
