Abstract
The utility model relates to medical instruments, and particularly relates to a double-cavity venous indwelling needle, which comprises a sleeve and a needle core; butterfly-shaped wings are arranged at the outer wall of the front part of the sleeve; the sleeve comprises a main cavity pipe and a secondary cavity pipe; a main pipe body of the secondary cavity pipe is attached to that of the main cavity pipe to form a whole; the needle core is arranged in the main cavity pipe. According to the double-cavity venous indwelling needle, demands of management on liquid of patients in a hospital and the venous channel establishing in a perioperative period can be met, patient pain is reduced, and the nursing cost and cost of the patient can also be reduced; in addition, the double-cavity venous indwelling needle can better ensure the safety of the patient compared with a central venous channel with higher risk.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically, relates to a kind of two-chamber venous detaining needle.
Background technology
In clinical position, ward transfusion, especially in art, transfusion often will be applied multi-medicament simultaneously, and some medicine is because the different or unknown 5 use consequences of acid-base value can not same channel application, this just need to open many venous channels, so not only increased nursery work, increased patient painful, sometimes also because individual patient difference condition is difficult to set up many venous channels.
In addition,, along with the improvement day by day of medical condition, the patient of postoperative indwelling anesthesia analgesia pump is increasing.Anesthesia analgesia pump needs certain liquid continuous instillation to maintain stable blood drug level, and postoperative patient liquid management can not be accomplished 24 hours persistent instillations, therefore, often causes the uncertain of anesthesia analgesia effect.In addition, in clinical trial, find, by threeway conduit and liquid, be incorporated to instil and implement anesthesia analgesia, due to the impact of liquid for analgesia pump cracking pressure, the output speed of analgesia pump liquid and analgesia pump are exported separately and are had obvious difference, and this is very unfavorable to the pain management of critical patient and Security Target.
Utility model content
The purpose of this utility model is, a kind of two-chamber venous detaining needle is provided, to solve upper technical problem.
For achieving the above object, the technical scheme that this utility model adopts is:
A two-chamber venous detaining needle, comprises sleeve pipe and nook closing member, and the anterior outer wall of sleeve pipe is provided with the butterfly wing; It is characterized in that: described sleeve pipe comprises main lumen and secondary lumen, the main pipe of described secondary lumen is attached on the main pipe of main lumen, becomes one; Described nook closing member is arranged in main lumen.
A kind of improvement as technique scheme: the body of the liquid feeding end part of described secondary lumen and the body of main lumen liquid feeding end part are separated from each other, Y-shaped shape; The feed liquor port of described secondary lumen is provided with secondary chamber end cap.
Another kind as technique scheme improves: the liquid feeding end of described secondary lumen is connected with medical plastic hose, and the body of described medical plastic hose and main lumen liquid feeding end part is separated from each other, and is provided with secondary chamber end cap at the feed liquor port of medical plastic hose.
Say further:
The internal diameter of described main lumen is 0.7mm, 0.9mm, 1.1mm or 1.3mm; The internal diameter of described secondary lumen is 0.7mm.
The entire length of described remaining needle is 19mm, 25mm or 32mm.
Beneficial effect: compared with prior art, this utility model is simple in structure, reasonable in design, while puncturing in the preoperative, use two-chamber venous detaining needle described in the utility model, not only can facilitate and in art, anaesthetize medication, and, postoperatively can keep somewhere a special pipeline for connecting anesthesia analgesia pump, thereby can guarantee stable analgesic output, reach and continue constant analgesic object.Therefore, this utility model can meet the application of inpatient liquid management and the foundation of perioperative venous access, can reduce patient's misery again, also can save nursing cost and patients ' expenses, and, the central vein path higher with respect to risk, this utility model more can ensure patient's safety.
