Embodiment 1

[0020] An adrenal vein blood collection catheter assembly, in order to solve the problem that the existing adrenal vein blood collection catheter is not easy to grasp the catheter and does not protect the blood collection needle, as a preferred embodiment, as figure 1 , figure 2 and image 3 As shown, a catheter assembly 1 is included. The catheter assembly 1 includes a catheter 10. The outer wall of the catheter 10 is provided with a limit block 15. The hand grasps the limit block 15 to provide a fulcrum for the delivery of the blood collection needle 13, and pushes the limit block 15 into the blood vessel. , control the depth of the blood collection needle 13, so as to facilitate the control of the depth of the catheter 10, avoid the damage caused by the catheter 10 being too deep, and the blood collection blockage caused by too shallow, which is conducive to the efficiency of adrenal vein blood collection.

[0021] Further, an external thread sleeve 14 is arranged above t...

Abstract

The invention relates to a catheter assembly, in particular to an adrenal vein blood sampling catheter assembly. The adrenal vein blood sampling catheter assembly comprises a catheter assembly body, wherein the catheter assembly body comprises a catheter; a limiting block is arranged on the outer wall of the catheter; an external threaded sleeve is arranged at the upper part of the limiting block;a protection device is in threaded connection to the outer wall of the external threaded sleeve, and comprises a rotating sleeve; internal threads are formed in the inner wall of the rotating sleeve;the internal threads are in threaded cooperation with the external threaded sleeve; a safety hat is arranged at the end of the rotating sleeve in a communicating manner; the catheter comprises a catheter front end; the external thread sleeve is located below the front end of the catheter; a sliding block is arranged at the front end of the catheter in a communicating manner; and a blood samplingneedle is arranged at the end of the sliding block in a communicating manner. Through the adoption of the adrenal vein blood sampling catheter assembly disclosed by the invention, the catheter is convenient to grasp and hold to control the feeding depth, the situation that the blood sampling needle accidentally stabs medical personnel can be avoided, and the safety is higher.

Description

technical field [0001] The invention relates to a catheter assembly, in particular to an adrenal vein blood collection catheter assembly. Background technique [0002] Adrenal vein blood sampling is an interventional examination method that selectively inserts a catheter into the adrenal vein to collect blood samples. It is mainly used for the differential diagnosis of primary aldosteronism (PA). The technical requirements are high and difficult. At present, catheters are used for adrenal vein catheterization for blood collection. However, it is difficult for medical staff to grasp the catheter for blood collection, which makes it difficult to control the depth of the blood collection needle. Moreover, the blood collection needle connected with the catheter in the prior art is After blood collection, there is no effective protective device, and the blood collection needle is directly exposed to the outside, which is likely to cause stabbing injuries to medical staff and caus...
