Description
Technical Field
The utility model relates to a medical device, in particular to a venous indwelling needle which can deliver a tube by one hand when puncturing is convenient.
Background
The needle head part of the venous indwelling needle (venous trocar) consists of a soft catheter (cannula) which can be indwelling in the blood vessel and a stainless steel puncture guiding needle core. When in use, the catheter and the needle core are punctured into the peripheral superficial vein together, the needle core is withdrawn, and the catheter is only left in the vein for transfusion treatment. The venous indwelling needle has the advantages of easiness in puncture, reduction in repeated puncture, reduction in puncture pain, protection of blood vessels of patients, improvement of satisfaction of the patients, improvement of nursing quality and the like, and is wide in clinical application.
The vein indwelling needle is clinically used, a puncture indwelling needle is popularized at present by applying a one-hand tube delivery method, the one-hand tube delivery method only needs one nurse to operate, a left hand always fixes a puncture part, a right hand punctures a vein and then delivers a tube by one hand, and due to coordination and cooperation of the two hands, the operation is continuous, the puncture angle and the puncture direction can be effectively adjusted in time, the tube delivery is easy and successful, the puncture success rate is higher [ Cai's quiet, picnic ]. 113-114. spring, zhangqian, lie, etc. application effect of one-hand tube feeding in puncture tube of pediatric indwelling needle, journal of liberty military care, 2014, 31 (17): 74-76, li, design and application of a novel venous indwelling needle, family medicine (medical choice), 2020, (1A): 383-383.].
However, the structure of the existing venous indwelling needle is not beneficial to tube delivery by a single hand, and the use is very inconvenient. How to further effectively improve the success rate of the single-hand tube feeding puncture of the venous indwelling needle, reduce the waste caused by puncture failure, relieve the pain of the patient caused by the re-puncture, further improve the satisfaction degree of the patient and is a problem which is expected to be solved by medical workers all the time. Therefore, researchers have made corresponding research and improvement on the design and construction of the venous indwelling needle. The venous indwelling needle provided by the document [ Lihao, a venous indwelling needle, China patent, CN200420117241.6.2006-05-17 ], is characterized in that a vertical handheld piece is arranged on the upper surface of a puncture needle base, a horizontal gasket is arranged on the side surface of the puncture needle base (an inclined plane is arranged on the lower surface of the front end of the gasket, and a parallel sliding rail is arranged on the upper surface of the gasket), a handheld lateral piece is arranged on the side surface of the indwelling needle base, and a parallel sliding groove is arranged on the lower surface of the handheld lateral piece, so that the venous indwelling needle can adapt to users with different puncture habits, and can be operated by a single hand. The document (Schutlerian, disposable single-hand tube-feeding type vein indwelling needle, Chinese patent CN201220089871.1.2013-05-01) designs a disposable single-hand tube-feeding type vein indwelling needle with an anastomotic needle handle and anastomotic side wings, which can facilitate the thumb of the right hand to push a cannula into a blood vessel and simplify the operation flow of single-hand tube feeding. The patent No. CN200620114190.0.2007-04-25 discloses an improved puncture needle seat and an improved indwelling needle seat, wherein the puncture needle seat is provided with a toothed pulley and a sliding groove, the indwelling needle seat is provided with a toothed sliding block, the speed and the depth of a tube are controlled by rotating the pulley through a finger, and the tube placing operation can be completed by one hand. The document (Zhang Tong Jun, Sunjianfei, Weilan Shuang, etc. single hand operated venous indwelling needle, Chinese patent CN201320288556.6.2013-10-09.) designs an indwelling needle sleeve with a side wing, wherein the sleeve is provided with a spring block, a clamping groove and an activation button, the needle core is provided with a spring and a clamping hook, and the single hand operation is performed in the process of withdrawing the needle core and pushing the sleeve, so that the needle running is reduced or avoided. The novel indwelling needle designed by the Chinese patent CN201910002970.8.2019-03-12 has a cavity structure, wherein a blocking plug and a stop block are fixedly connected, and a compression spring is sleeved, so that the single-hand automatic tube feeding can be realized in the venipuncture process, the puncture failure caused by the manual tube feeding and withdrawing is solved, and the puncture success rate of the indwelling needle is improved. The improvement of above vein indwelling needle has made things convenient for one-hand pipe delivery to a certain extent, but all has the design structure numerous, additional part numerous, production complex assembly scheduling problem for clinical user is difficult for mastering the operation key, has increased the degree of difficulty of puncture pipe delivery, causes easily to put the pipe failure. The Chinese patent CN201520025716.7.2015-06-24 discloses an auxiliary device convenient for delivering a tube by one hand during the puncture of a venous indwelling needle, although the auxiliary device can facilitate the tube delivery by one hand during the puncture of the venous indwelling needle, the auxiliary device needs to be assembled on the tube diameter of a tube seat of the indwelling needle sleeve before use, and after the puncture is finished, the auxiliary device needs to be taken down and recycled after recovery, sterilization and disinfection, the operation is relatively complex, the auxiliary device is not disposable, and the risk of cross infection among patients exists.
Therefore, there is a need to develop a venous retention needle which has a relatively simple structure and facilitates tube delivery by one hand during puncture.
