Abstract
The vein indwelling needle blood back-flow device of the utility model relates to a medical appliance, provided with a needle core (7), a trocar (6), a needle tube (1) and a vein cap (8). The utility model is mainly characterized in that a blood back-flow cavity (5) and a soft tube (3) are increased between the needle core (7) and the needle tube (1), and the outer part of the needle core is coated with the trocar (6). The vein indwelling needle blood back-flow device has the advantages that the operation is easy, the success ratio of the venous puncture is high, and the blood back-flow of the suction is clear. The utility model is particularly suitable for the vein site puncture of the scalp vein, the external jugular vein, the chest and abdominal wall superficial vein and other veins where the blood flow is slow and the blood pressure is low, and the new nurses can easily master the use.
Description
This utility model relates to technical field of medical.
The venous detaining needle of domestic and foreign hospitals use at present, when scalp vein, external jugular vein, breast superficial epigastric vein etc. are located to carry out venipuncture, blood flow is slow, blood pressure is low because of this is located, blood back is not obvious, the nurse needs repeated localised puncture and suction just can finish the venipuncture task at this place, so both increased patient's misery, also increased nurse's venipuncture difficulty, moreover puncture success rate had been lower.
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of success rate of venous puncture height is provided, the apparent device of blood back.
The purpose of this utility model realizes by following measure, this device has needle tubing (1), pin stamen (7), is wrapped in the vein medicated cap (8) of the outer trocar (6) of pin stamen and screw-in trocar afterbody, it is characterized in that blood back cavity (5) left end and pin stamen (7) are connected, blood back cavity (5) right-hand member and the evagination of flexible pipe (3) connect to be chewed (4) and links to each other, and recessed connecing chewed (2) and linked to each other with needle tubing (1) within the other end of flexible pipe (3).
The material of blood back cavity (5) is a hard transparent plastic, and the evagination at flexible pipe (3) two ends connects to be chewed (4) and indent and connect the material of chewing (2) and be hard transparent plastic.
This utility model compared with the prior art, have easy and simple to handle, success rate of venous puncture height, the advantage that blood back is clear.
Description of drawings is as follows:
Fig. 1 draws back the structural representation of blood device for venous detaining needle.
Fig. 2 is intravenous structural representation for the trocar is retained in.
The 1-needle tubing, the 2-indent connects chews, the 3-flexible pipe, the 4-evagination connects to be chewed, 5-blood back cavity, the 6-trocar, 7-pin stamen, 8-vein medicated cap.
This utility model will be further described in conjunction with the accompanying drawings, this device is aseptic disposable product, the trocar (6), pin stamen (7), blood back cavity (5), flexible pipe (3) are linked together during product export, and aseptic sealed packages, needle tubing (1) and vein medicated cap (8) they are respectively disposable aseptic sealed packages.During use, open above-mentioned three kinds of packings, earlier the needle tubing (1) and the indent of flexible pipe (3) are connect and chew (2) and link to each other, need carry out the position of venipuncture patient, sterilization back nurse's hands is brought back haemocoele (5) and is done venipuncture, pin stamen (7) thrusts vein, with needle tubing (1) suction, make it produce negative pressure, blood clearly flows into blood back cavity (5), slowly send into intravenous with being about to the trocar (6), pin stamen (7) is withdrawed from then venipuncture success, immediately the vein medicated cap is screwed in the afterbody of the trocar (6), use adhesive plaster that the trocar (6) is fixed on skin at last, for patient infusion etc. is got ready.The trocar (6) was generally kept somewhere about five days at intravenous.
Claims (3)
1, a kind of venous detaining needle that relates to medical apparatus and instruments is drawn back the blood device, have needle tubing (1), pin stamen (7), be wrapped in the pin stamen trocar (6) outward and the vein medicated cap (8) of screw-in trocar afterbody, it is characterized in that blood back cavity (5) left end and pin stamen (7) are connected, blood back cavity (5) right-hand member and the evagination of flexible pipe (3) connect to be chewed (4) and links to each other, and recessed connecing chewed (2) and linked to each other with needle tubing (1) within the other end of flexible pipe (3).
2, venous detaining needle according to claim 1 is drawn back the blood device, and the material that it is characterized in that said blood back cavity (5) is a hard transparent plastic.
3, venous detaining needle according to claim 1 is drawn back the blood device, it is characterized in that protruding connecing chewed (4) and indent to connect the material of chewing (2) be hard transparent plastic outside the said flexible pipe (3).
