Abstract

A intravenous transfusion cannula device comprises a puncture needle and a cannula, of which the front end of the cannula is a solid taperedtoe; the cannula is provided at least with an one-way flapper; the solid taperedtoe consists of a X-ray display piece; a transfusion three-way switch is positioned at the tail end of the puncture needle; the side port of the three-way switch is communicated with a washpipe for transfusion; a layer of transparent medical film cannula is added on the cannula; the front end of the film cannula is stuck to the tail end of the puncture needle; a length indicator line is arranged on the external face of the cannula. The display piece can be seen by a X-ray meter when the cannula reaches the vein through a puncture needle hole, and inputting length of the cannula can be convenient grasped; once the back blood is condensed in the puncturing site or outside the cannula, the coagulum can be discharged by a washpipe at the side port; the cannula is advanced by hand outside the film cannula; the cannula is always kept in the aseptic condition; the defect of the non backflow vein cannula can be eliminated.

Description

The venous transfusion Intubaction device

[technical field]

This utility model relates to medical apparatus, and the venous transfusion Intubaction device that specifically a kind of nothing is backflowed is applicable to transfusion, blood transfusion, high nutrient etc.

[background technology]

The disclosed a kind of human body of China utility model patent CN85204163U does not have the venous cannulation of backflowing and has used more than two decades, finds some shortcomings in the practice, and for example, intubate can't be known the position that it arrives after arriving vein through the puncture pin hole; When puncture row idol has blood back to condense within the pin hole outside the intubate and can not washing pipe, or the like, further improved needs are arranged.

[summary of the invention]

This utility model provides a kind of venous transfusion Intubaction device, is intended to solve above-mentioned human body and does not have the weak point that the venous cannulation that backflows exists at present.

Improvement project of the present utility model is such: a kind of venous transfusion Intubaction device, comprise puncture needle and intubate, intubate arrives intravenous by the puncture pin hole, end is solid tip before the intubate, intubate has at least one unidirectional flap valve, it is characterized in that comprising in the described solid tip X line displaying block.After intubate arrives vein through the puncture pin hole, use the X-ray instrument just can see displaying block, know the position that the intubate front end arrives.

Described puncture needle tail end can be provided with a transfusion three-way cock, intubate pass three-way cock enter the puncture pin hole enter vein again, the side mouth of three-way cock communicates with the washing pipe tube for transfusion, in case there is blood back to condense within the pin hole outside the intubate, can change the connected relation of three-way cock, by the capable washing pipe of this side mouth, continue to advance intubate behind the eliminating coagula.

Described intubate is outer can also to add cover layer of transparent medical film sleeve pipe, and the front end of membrane casing and puncture needle tail end are bonding, can advance intubate at membrane casing external hand push like this, and the intubate that remains in the membrane casing is in aseptic condition.

Described intubate outer surface can be provided with the length mark line, is convenient to grasp intubate and enters venous length when advancing intubate.

This utility model is taked technique scheme, can eliminate original human body substantially and not have the existing defective of the venous cannulation of backflowing.

[description of drawings]

Accompanying drawing is this utility model structural representation.

Labelling among the figure: puncture needle 1, three-way cock 2, side mouth 21, intubate 3, X line displaying block 31, unidirectional flap valve 32, length mark line 33, membrane casing 4

[specific embodiment]

Below in conjunction with accompanying drawing and most preferred embodiment the specific embodiment is described further.

As shown in drawings, a kind of venous transfusion Intubaction device comprises puncture needle 1 and intubate 3, intubate 3 arrives intravenous by the puncture pin hole, end is solid tip before the intubate 3, and intubate 3 has at least one unidirectional flap valve, and it is identical that these features and existing human body do not have the venous cannulation of backflowing.This utility model is comprising an X line displaying block 31 in the solid tip of intubate 3, clinical use X-ray instrument can be seen displaying block 31, knows the position that intubate 3 front ends arrive.Displaying block 31 uses radiopaque material, for example iodized oil or bismuth metal, barium etc., and its size does not expose being wrapped up by the solid tip of intubate 3 exceeds.Puncture needle 1 tail end is provided with a transfusion three-way cock 2, two straightthrough ports (among the figure mark) that intubate 3 is passed three-way cock 2 enter puncture needle 1 hole and enter vein again, the side mouth 21 of three-way cock 2 communicates with washing pipe tube for transfusion (not shown), in case have blood back to condense within the pin hole outside the intubate 3, continue to advance intubate 3 after can getting rid of blood clot by side mouth 21 washing pipes earlier.Intubate 3 adds cover layer of transparent medical film sleeve pipe 4, and the front end of membrane casing 4 and puncture needle 1 tail end are bonding, and be bonding with three-way cock 2 tail ends if any 2 of three-way cocks.Intubate 3 outer surfaces are provided with length mark line 33, grasp entering venous length during for propelling intubate 3.After intubate 3 arrives Len reqs, puncture needle 1, three-way cock 2, membrane casing 4 to be removed in the lump, intubate 3 is kept somewhere intravenouss for the instillation usefulness, and the tube sealing that finishes of instiling is standby.

Claims
