Abstract
This utility model belongs to medical articles for use technical field, be specifically related to a kind of vessel clamp, comprise a body, one side of this body is provided with elastic arm, opposite side is provided with micro-cranking arm, described elastic arm and micro-upper through hole all offering for tube for transfusion cross-under of cranking arm, on described elastic arm and body, be equipped with for locking the lobe of conduit, described micro-through hole top of cranking arm is provided with back-off, the free end of described elastic arm and back-off clamping, it is characterized in that: the top of described back-off is micro-extension of cranking arm, vessel clamp under naturalness time the free end of elastic arm and the free end of extension contact.This utility model is simple in structure, can prevent that conduit is extruded before closure or it is flat to squeeze, and vessel clamp can hang on any part of conduit simultaneously, easy to use.
Description
Technical field
This utility model belongs to medical articles for use technical field, is specifically related to a kind of vessel clamp.
Background technology
Vessel clamp is a device on disposable transfusion device, is mainly used in opening or closure catheter for closing folder, and controls liquid flowing in tube for transfusion, and be the necessary of infusing in clinical medicine.The patent that for example patent No. is 201320696047.7, can find out from the Figure of description of this patent, latch 11 and push extended distance between fast 211 almost and the compression face 123 at locking conduit place and the distance of pushing between fast 211 equate.Above-mentioned vessel clamp of the prior art under naturalness because the opening between two free arms is larger, as shown in the simple and easy schematic diagram of Fig. 1, once be subject to the extended distance that extraneous extruding will be dwindled free arm, even be connected together, as shown in the simple and easy schematic diagram of Fig. 2, the conduit that causes being equipped with vessel clamp is extruded or squeezes flat, is just difficult to restore to the original state for a long time in this state downcomer.And in the ordinary course of things, the conduit that vessel clamp is housed all folds to package joint sealing transportation, be more prone to be squeezed, therefore there is certain defective products in untapped transfusion device, if doctor does not find these defective products and just first transfusion pinprick is entered in patient body, this will bring the human body and spiritual misery to patient, and consequence is hardly imaginable.
Summary of the invention
This utility model, for the deficiencies in the prior art, provides a kind of vessel clamp, prevents that conduit is extruded before closure or it is flat to squeeze, and vessel clamp can hang on any part of conduit simultaneously, easy to use.
The main technical schemes that this utility model adopts is: a kind of vessel clamp, comprise a body, one side of this body is provided with elastic arm, opposite side is provided with micro-cranking arm, described elastic arm and micro-upper through hole all offering for tube for transfusion cross-under of cranking arm, on described elastic arm and body, be equipped with for locking the lobe of conduit, described micro-through hole top of cranking arm is provided with back-off, the free end of described elastic arm and back-off clamping, it is characterized in that: the top of described back-off is micro-extension of cranking arm, vessel clamp under naturalness time the free end of elastic arm and the free end of extension contact.
This utility model also adopts following attached technical scheme:
In above-mentioned vessel clamp, the vertical dimension between two lobe that arrange on described elastic arm and body is between the interior path length and outer path length of tube for transfusion.
In above-mentioned vessel clamp, the outer surface of described elastic arm is provided with anti-skidding muscle.
In above-mentioned vessel clamp, the inner surface of described extension is consistent with the direction of plumb line.
Adopt the beneficial effect that this utility model brings to be: to be provided with extension on cranking arm vessel clamp is micro-, can effectively to prevent that tube for transfusion from folding vessel clamp to be in transit subject to the effect of external force and to push or squeeze flat conduit; Vertical dimension between two lobe that arrange on elastic arm and body, can be so that the vessel clamp on the tube for transfusion under plumbness can hang on any part of conduit between the interior path length and outer path length of tube for transfusion, easy to use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, be described further:
Fig. 1 is the opening design sketch of vessel clamp two free arms under naturalness in prior art.
Fig. 2 is the design sketch that when two free arms of vessel clamp contact in prior art, conduit is extruded.
Fig. 3 is the design sketch that the vessel clamp of this utility model carrying pipe is extruded at naturalness downcomer.
Fig. 4 is two free arms of this utility model vessel clamp design sketchs that conduit is extruded while contacting.
Fig. 5 is the sectional structure chart of this utility model vessel clamp.
The label that wherein component names is corresponding is as follows:
Body 1, elastic arm 2, micro-ly crank arm 3, through hole 4, lobe 5, back-off 6, extension 7, anti-skidding muscle 8.
The specific embodiment
As in Figure 3-5, a kind of vessel clamp, comprise a body 1, one side of this body 1 is provided with elastic arm 2, opposite side is provided with micro-ly cranks arm 3, described elastic arm 2 and micro-cranking arm on 3 all offer the through hole 4 for tube for transfusion cross-under, on described elastic arm 2 and body 1, be equipped with for locking the lobe 5 of conduit, described micro-through hole 4 tops of 3 of cranking arm are provided with back-off 6, the free end of described elastic arm 2 and back-off 6 clampings, the top of described back-off 6 is micro-extension 7 of 3 of cranking arm, because extension 7 is long, vessel clamp under naturalness time the free end of elastic arm 2 and the free end of extension 7 can contact, can effectively prevent that tube for transfusion from folding in transit vessel clamp to be subject to the effect of external force and pushing or squeeze flat conduit.
In above-mentioned vessel clamp, vertical dimension between two lobe 5 that arrange on described elastic arm 2 and body 1 is between the interior path length and outer path length of tube for transfusion, the benefit of design is to prevent that vessel clamp is arbitrarily in any position like this, especially can be so that the vessel clamp on the tube for transfusion under plumbness can hang on any part of conduit, very easy to use.
In above-mentioned vessel clamp, the outer surface of described elastic arm 2 is provided with anti-skidding muscle 8, plays anti-skidding effect.
In above-mentioned vessel clamp, the inner surface of described extension 7 is consistent with the direction of plumb line, can so that elastic arm 2 downwards firmly time on a more moderate active force.
When vessel clamp is used, when needs stopping infusion, medical worker's thumb is placed on anti-skidding muscle 8 places, forefinger is placed on the lower surface of body 1, then firmly pushes elastic arm 2, and elastic arm 2 is down sliding on extension 7, until stop when back-off 6 position, complete click action, now conduit is crowded flat, and the liquid in conduit stops flowing.When needs continue transfusion, the free end of elastic arm 2 is departed from and can be realized from back-off 6.Because each medical worker's height is different, before giving patient infusion, medical worker can, according to the height of oneself, move to vessel clamp under suitable height and infuse.While needing vessel clamp integral body to move down, medical worker's a hands is arrested the upper end of conduit, and another hands is arrested vessel clamp firmly a little downwards; While needing vessel clamp integral body to move up, medical worker's a hands is arrested the lower end of conduit, and another hands is arrested vessel clamp a little upwards firmly.
This utility model is not limited to above embodiment, and every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, while applying to transfuse blood as vessel clamp, within dropping on equally protection domain of the present utility model.
