Description

Water stop clamp
Technical Field
The invention belongs to disposable medical equipment, and particularly relates to a water stop clamp.
Background
At present, the intravenous needle is generally applied clinically, the intravenous needle generally comprises a needle component, a catheter component, a hose, a one-hand clamp or sheet clamp, an end cap, a color tee joint and a heparin cap or positive pressure connector, the hose is closed by the intravenous needle, the sheet clamp or the one-hand clamp is used for closing the hose, when the intravenous needle is used for intravenous placement clinically, blood is easy to flow back into the indwelling hose of the intravenous needle in a closing state, and the thrombus is easily formed due to blood blockage after a long time, so that medical accidents are caused.
Disclosure of Invention
The technical problems to be solved by the invention are as follows: the existing water stop clamp is generally locked by itself, when the water stop clamp is locked, the compression part (the part for compressing the hose) can rebound due to rebound of the clamping part, so that the volume of the hose at the front end of the dead point is increased, blood in a human body flows back into the indwelling hose, and thrombus is easy to form.
The invention aims to provide an improved water stop clamp, which overcomes the defect that the existing indwelling needle has the defects that after a tube sealing sheet clamp or a single-hand clamp is closed, blood flows back into an indwelling hose to form thrombus, so that medical accidents are caused.
The purpose of the invention is realized in the following way:
a water stop clip, characterized in that: the water clamp comprises a water clamp body with a C-shaped outer contour, wherein the water clamp body comprises a base, a left part and a right part are respectively fixed on two sides of the base, and a notch is arranged between the left part and the right part; the left part is a triangle movable frame, the lower part is a pressing part, the tail end of the upper part is a movable end, and the fixed end of the movable frame is fixed with the base into a whole; the lower part of the right part is a fixed end fixed with the base, the upper part of the right part is a clamping buckle, and an elastic wedge block extends inwards from the part between the lower part and the upper part; the left and right sides of the base are respectively provided with a left through hole and a right through hole through which the hose penetrates, the middle part of the base is provided with a bulge, a hose clamping channel is formed between the elastic wedge block and the base, and the width of the left part of the hose clamping channel is smaller than the outer diameter of the hose; when the movable end of the left part is clamped with the clamping buckle of the right part, the pressing part of the left part presses the bulge of the base to enable the hose to be closed.
When the movable end of the left part is pressed downwards until the movable end abuts against the tail end of the left side on the clamping buckle of the right part, at the moment, the clamping buckle of the right part moves backwards and drives the elastic wedge block to move backwards and tilt upwards, so that a hose clamped by the elastic wedge block is loosened, and the amount of liquid medicine stored in the hose is increased; when the movable end of the left part is continuously pressed downwards to the lower part of the clamping buckle of the right part, the clamping buckle of the right part is reset, the elastic wedge block moves forwards and resets and simultaneously extrudes the hose, and the hose and the liquid medicine in the hose are extruded to enable the liquid medicine to flow forwards to form forward flow.
The lower part of the left part is a smooth transition pressing part.
When the movable end of the left part is clamped with the clamping buckle of the right part, the pressing part of the left part presses the right side of the bulge of the base to enable the hose to be closed.
Compared with the prior art, the invention has the following good effects due to the application of the technology: when the movable end of the left part 1 is pressed downwards, the movable end presses the clamping buckle of the right part, so that the clamping buckle of the right part moves backwards and drives the elastic wedge block to move backwards and tilt upwards slightly, so that the clamping hose is loosened, the amount of liquid medicine stored in the tube becomes large, when the movable end of the left part is pressed downwards to the position under the clamping buckle of the right part, the clamping buckle of the right part is reset, the elastic wedge block also moves forwards to reset the extrusion hose, the liquid medicine in the tube flows forwards to form forward flow due to extrusion, blood is prevented from flowing back into the indwelling hose, thrombus formation is avoided, and hidden danger affecting the safety of a patient is eliminated.

Fig. 1 is a schematic view of the present invention holding a hose.
Detailed Description
In the figure, the water stop clamp comprises a water clamp body with a C-shaped outer stop contour, the water clamp body comprises a base 3, a left part 1 and a right part 2 are respectively fixed on two sides of the base 3, and a notch is arranged between the left part 1 and the right part 2.
The left part 1 is a movable frame with a general triangle shape, the lower part (namely one corner of the triangle) is a pressing part 1b with smooth transition, the tail end (namely the other corner of the triangle) of the upper part is a movable end 1a, and the fixed end (namely the last corner of the triangle) is fixed with the base 3 into a whole.
The lower part of the right part 2 is a fixed end fixed with the base 3, the upper part is a clamping buckle 2a, and an elastic wedge block 2b extends inwards at the part between the lower part and the upper part.
The left and right sides of base 3 are equipped with left through-hole 3a and right through-hole 3c that hose 4 penetrated respectively, and the middle part is equipped with a arch 3b, form the hose clamp path between elastic wedge 2b and the base 3.
When the movable end 1a of the left part 1 is engaged with the engaging button 2a of the right part 2, the pressing part 1b of the left part presses the protrusion 3b of the base 3 to close the hose 4, thereby preventing the flow of the liquid medicine in the tube.
The left width of the hose clamp is smaller than the outer diameter of the hose 4.
When the movable end 1a of the left part 1 is engaged with the engaging button 2a of the right part 2, the pressing part 1b of the left part presses the right side of the protrusion 3b of the base 3 to close the flexible tube 4, thereby preventing the flow of the liquid medicine in the tube. The force of pressing the right side of the protrusion 3b to make the hose 4 flow forward again is more effective.
When the movable end 1a of the left part 1 is pressed downwards until the movable end 1a is propped against the left end part of the clamping buckle 2a of the right part 2, meanwhile, the clamping buckle 2a of the right part 2 is moved backwards by 3b and drives the elastic wedge block 2b to move backwards and slightly upwarp, so that the clamping hose is loosened, the hose at the left part of the hose clamping channel is expanded, the stored liquid medicine in the hose is increased, and the pressing part 1b and the bulge can lock the hose 4; when the movable end 1a of the left part 1 continues to be pressed downwards to the lower part of the clamping buckle 2a of the right part 2 (see reference numeral 2c in the figure), the clamping buckle 2a of the right part 2 is reset, the elastic wedge block 2b also moves forwards and resets and simultaneously presses the hose 4, because the hose 4 and the liquid medicine in the hose cannot be retracted backwards due to the pressing (because the pressing part 1b and the bulge can lock the hose 4) and only can enable the liquid medicine to flow forwards to form forward (rightward) flow to squeeze blood, so that the blood is prevented from flowing back into the indwelling hose, thrombus formation is avoided, the safety of a patient is ensured, the service time of the indwelling needle is prolonged, and the medical cost of the patient is reduced.
The above-described examples are merely preferred embodiments of the present invention. It should be noted that variations and modifications can be made to the above-described fitting by those skilled in the art without departing from the principles of the present invention, which are also to be considered as falling within the scope of the present invention.
