Disposable infusion hose type transfusion needle and infusion method thereofTechnical field
The present invention relates to a kind of field of medical, specifically a kind of disposable infusion needle and infusion method thereof.
Background technology
Bring into use in recent decades remaining needle, complete vascular puncture backed off after random metal needle, plastic catheter is stayed in blood vessel and is continued transfusion, has solved metal needle in the process of traditional infusion and has stayed endovascular defect.But due to the complex structure of remaining needle, cost is high, remaining needle is only for needing the inpatient of transfusion for continuous several days, this transfusion needle can be retained in patient's blood vessel, transfusion repeatedly, so remaining needle can not replace the metal transfusion needle of disposable infusion, remaining needle only accounts for the very small scale of transfusion needle consumption for clinical transfusion, and most transfusions can only be with the metal needle with certain hazardness.
Patent Office of the People's Republic of China disclosed on June 7th, 2006open (bulletin) number iscN2785609Y, patent name is the patent of self-styled preventing thrombosis venous detaining needle and using method thereof, this utility model belongs to medical apparatus field, particularly a kind of composite vein transfusion needle.It is by transfusion needle and puncture needle is compound forms, transfusion needle is made up of transfusion needle sleeve pipe and Transfusion needle pipe, puncture needle is made up of puncture needle sleeve pipe and puncture needle body, Puncture needle sleeve bore is slightly larger than transfusion needle sleeve pipe external diameter, and transfusion needle sleeve pipe passes puncture needle sleeve pipe and is slidably matched with puncture needle sleeve pipe.All there are sleeve pipe and handle in transfusion needle and puncture needle rear portion, convenient operation, and needle tip is slightly inwardly stuck up, to guarantee safety.When use, first transfusion needle is retreated, exposes puncture needle head, prick after blood vessel at puncture needle head, by transfusion needle be advanced to transfusion needle front end exceed needle tip can start transfusion.When this composite vein transfusion needle can ensure patient's transfusion part activity, needle point can not puncture vein blood vessel and cause the hemorrhage bulge of vein blood vessel by secondary, guarantees safe infusion, reduces patient suffering and medical worker's workload, improves curative effect.
There is essential distinction in above-mentioned patent and this patent, the difference of the problem of solution, the technology difference of generation.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of cost low, easy to operate, can alleviate patient's misery, and improve the disposable infusion hose type transfusion needle of quality of medical care.
Another object of the present invention is that a kind of method of utilizing disposable infusion hose type transfusion needle to infuse is also provided.
For achieving the above object, the technical solution adopted in the present invention is:
Disposable infusion hose type transfusion needle, it is to be made up of puncture needle, soft Transfusion needle pipe, sealer and needle stand, wherein, sealer is to be made up of connecting tube, fixture, sealing flexible pipe, one end of flexible pipe and the medicinal liquid delivery outlet UNICOM of needle stand for described sealing, the other end is connected with soft Transfusion needle pipe by connecting tube, and the needle point of described puncture needle is successively through needle stand, sealing flexible pipe, connecting tube and soft Transfusion needle pipe, and described fixture is clamped in described sealing with on flexible pipe.
Sealing in described sealer is 2～5mm by the length of flexible pipe.
Described sealing flexible pipe is to be made up of PVC material, silica gel material or latex material.
Described sealing is not less than 0.4mm by the pipe thickness of flexible pipe.
The external diameter of described soft Transfusion needle pipe is 0.4mm.
Described fixture is intermediate plate, liquid stopping clamp or actuator, preferably intermediate plate.
The pipe outer wall of the connecting tube in described sealer is provided with fin.
The medicinal liquid input of described needle stand directly connects with the joint of transfusion device, and this connecting mode cost used is minimum, is highly suitable in disposable infusion and uses.Certainly, can also use other connecting mode, such as: the medicinal liquid input of described needle stand connects with the transfusion needle of transfusion device by calparine cap, or the medicinal liquid input of needle stand also can be connected with the joint of transfusion device by positive pressure connector.
The method of utilizing disposable infusion hose type transfusion needle to infuse, comprise the following steps: A, penetrate vein blood vessel: by the needle point of puncture needle successively through needle stand, sealing flexible pipe, connecting tube and soft Transfusion needle pipe, described fixture is clamped in described sealing with on flexible pipe, and with clamp sealing flexible pipe, disposable infusion hose type transfusion needle is penetrated to vein blood vessel; B, puncture needle is extracted out from needle stand, after extraction, under the effect of fixture, sealing is sealed with flexible pipe; C, the medicinal liquid input of needle stand is connected with the joint of transfusion device; D, open the actuator on transfusion device, then sealing is opened with the fixture on flexible pipe, transfusion starts to carry out; E, infused after, disposable infusion hose type transfusion needle is extracted from vein blood vessel, complete transfusion.
Beneficial effect of the present invention:
1, owing to adopting above-mentioned version, complete the puncture needle of metal after vascular puncture and extract, only have soft flexible pipe to stay in blood vessel and continue transfusion, avoid the injury of metal needle to blood vessel, when patient activity, also can avoid mixed pin or puncture blood vessel;
2, alleviate patient's misery, and improve quality of medical care, the existing transfusion needle of same traffic is greater than puncture needle, the more little more easily puncture of pin, patient's pain is less, and such as No. 7 transfusion needle body diameters are 0.7mm, its flow is identical with the flow of the soft Transfusion needle pipe that puncture needle external diameter is 0.4mm, so the flow of soft Transfusion needle pipe is larger, therefore be conducive to treatment and first-aid patients;
3, because flexible pipe pin coordinates with the connection of transfusion device, adopt needle stand and joint, in the process of transfusion, without metal needle, the safer convenience of no-needle transfusion, easy to operate;
4, compared with venous detaining needle, structure and the technique of this patent are simple, easily realize, in use, positive pressure connectors etc., in the time of transfusion, do not need, therefore cost is lower, the cost of this patent can reduce by more than 50, compared with complicated venous detaining needle, can reduce by 75%, that is to say, the price of this patent be complicated venous detaining needle price 1/4th, therefore be extremely conducive to promotion and application;
5,, owing to setting up sealer, when puncture needle is extracted, sealer sealing, prevents blood backflow, has avoided cross infection.
