Abstract
A quick blood return indwelling needle, comprises conduit tube component, needle tubing assembly, calparine cap assembly; Wherein, needle tubing assembly is comprised of needle tubing, needle handle, conduit tube component is connected to form successively by sheath, conduit, catheter block, rivet, batching pig, calparine cap assembly is comprised of flexible pipe, heparin cap base, calparine cap, helmet, described needle handle be square without wing formula needle handle, needle handle front end is provided with fixedly exhaust apparatus; Described fixedly exhaust apparatus is comprised of filter membrane and aerofluxus obturating plug, and aerofluxus obturating plug is embedded in the groove of needle handle outer end, and the external diameter of aerofluxus obturating plug matches with the internal diameter of needle handle, between aerofluxus obturating plug and needle handle, is provided with filter membrane.This utility model can be observed fast blood back in piercing process, prevents from puncturing blood vessel or punctures for the second time, has improved safety and the effectiveness of product, has reduced medical-risk and doctor-patient dispute; Meanwhile, save medical personnel's the puncture time, improved work efficiency.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of novel safe and reliable remaining needle product.
Background technology
At present, disposable use venous detaining needle (the Y type that hospital is generally used, also be hermetic type) product, its structure is conduit tube component, needle tubing assembly, calparine cap assembly forms, needle tubing assembly is by needle tubing, the bonding composition of needle handle, conduit tube component is by sheath, conduit, catheter block, rivet, batching pig forms, calparine cap assembly is by flexible pipe, heparin cap base, calparine cap, helmet (as required) forms, have the following disadvantages: 1, because of the gap between conduit and needle tubing less (0.01mm left and right), in piercing process, blood enters needle tubing from blood vessel, from the side opening of needle tubing head end, enter again the needed time of conduit longer, while particularly puncturing to child, (child's blood vessel is thinner, indwelling needle catheter used is less) medical personnel are difficult to observe in time blood back phenomenon and can not stop in time puncture, 2, because piercing process Blood return time is longer, use medical personnel to be difficult to grasp paracentesis depth, thereby use remaining needle to puncture blood vessel, increased the risk of puncture, during 3, because of puncture, puncture after blood vessel, remaining needle can not puncture for the second time, thereby causes product rejection, need to change product and again puncture, 4, because of piercing process again, can affect patient's mood, cause doctors and patients to entangle part.
Filter membrane is to hold back the magnitude classification of former particle water, and fenestra is divided into micro-filtration membrane (MF) from coarse to fine
[1-2], ultrafilter membrane (UF), nano filter membrane (NF) and reverse osmosis membrane (RO).
Meanwhile, common needle handle is all band wing needle handle, has the following disadvantages: 1, because of the needle handle band wing, remaining needle needs to align needle point angle in process of production, makes needle handle and needle point first angle of chamfer in same direction, and its gradient is not more than 30 °; 2, in order to proofread and correct the angle requirement of needle handle and needle point, need needle point to rub positive operation with the hands in production process, this procedure easily causes needle point barb, and needle point is scrapped; 3, because of needle point barb phenomenon, in medical personnel's piercing process, be difficult for puncture, or patient's muscle taken out of external, to patient, cause suffering, cause doctor-patient dispute; 4, because in use patient (particularly child) easily moves, easily make the needle handle wing move, use needle tubing depart from blood vessel or puncture blood vessel, increased transfusion risk.
Utility model content
Technical problem to be solved in the utility model is for the deficiency in background technology, a kind of raising medical personnel work efficiency is provided, falls low-risk remaining needle.
In order to address the above problem by the following technical solutions: a kind of quick blood return indwelling needle, comprises conduit tube component, needle tubing assembly, calparine cap assembly; Wherein, needle tubing assembly is comprised of needle tubing, needle handle, conduit tube component is connected to form successively by sheath, conduit, catheter block, rivet, batching pig, calparine cap assembly is comprised of flexible pipe, heparin cap base, calparine cap, helmet, described needle handle be square without wing formula needle handle, needle handle front end is provided with fixedly exhaust apparatus; Described fixedly exhaust apparatus is comprised of filter membrane and aerofluxus obturating plug, and aerofluxus obturating plug is embedded in the groove of needle handle outer end, and the external diameter of aerofluxus obturating plug matches with the internal diameter of needle handle, between aerofluxus obturating plug and needle handle, is provided with filter membrane.
Described square is that cube, square are square without the cross section of wing formula needle handle without wing formula needle handle.
The ratio of described cubical length and width height is 3:1:1.
This utility model is provided with fixedly exhaust apparatus in needle handle outer end, for Exhaust Gas, stop blood to flow out, medical personnel with observing fast blood back in retained needle puncture process, prevent from puncturing blood vessel or puncture for the second time, the safety and the effectiveness that have improved product, reduced medical-risk and doctor-patient dispute; Meanwhile, save medical personnel's the puncture time, improved work efficiency.
Adopt square without wing formula needle handle, reduced single-blade or the double-vane of needle handle, reduced processing cost; Low price, has reduced patient medical cost; During transfusion, transfusion needle is easily fixed by infusion patch, difficult drop-off; Avoided in infusion process mobilely causing needle tubing to puncture blood vessel or needle tubing departs from blood vessel because of abnormal, improved safety and the effectiveness of product, reduced doctors and patients and entangled part.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1.
The specific embodiment
Embodiment 1: as shown in Figure 1, a kind of quick blood return indwelling needle, comprises conduit tube component, needle handle assembly, calparine cap assembly.
Needle tubing assembly is comprised of without wing formula needle handle 7 needle tubing 6, square, conduit tube component is connected to form successively by sheath 1, conduit 2, catheter block 3, rivet 4, batching pig 5, calparine cap assembly is comprised of flexible pipe 11, heparin cap base 12, calparine cap 14, helmet 13, and flexible pipe is provided with liquid stopping clamp 10.
The cube that the ratio that square is length and width height without wing formula needle handle shape is 3:1:1, square are square without the cross section of wing formula needle handle.
Square is provided with fixedly exhaust apparatus without wing formula needle handle front end.Fixedly exhaust apparatus is comprised of filter membrane 8 and aerofluxus obturating plug 9; Fixedly exhaust apparatus can make needle tubing endoporus communicate with the external world by filter membrane, can make the air in needle tubing discharge smoothly, plays the use of quick blood back.Aerofluxus obturating plug is embedded in the groove of needle handle outer end, and the external diameter of aerofluxus obturating plug matches with the internal diameter of needle handle, between aerofluxus obturating plug and needle handle, is provided with filter membrane.Filter membrane adopts polypropylene material to make, and can effectively by air and prevention liquid, flow out.
