A picc catheter fixation device that can increase the success rate of puncture

Abstract

The present invention provides a PICC catheterization fixation device capable of increasing the success rate of puncture, relates to the technical field of PICC catheterization, and solves the problem that once the PICC catheterization personnel holding the ultrasonic probe moves the ultrasonic probe to a certain position during application, It will lead to the failure of puncture due to the movement of the arm or the probe during catheterization, and the problem that accurate puncture cannot be achieved. A PICC tube fixing device capable of increasing the success rate of puncture, comprising a rectangular seat on which a front and rear reciprocating mechanism is slidably installed, and an up and down reciprocating mechanism is slidably installed on the front and rear reciprocating mechanism. The PICC tube inserter can twist the two butterfly fastening screws B along the threaded through hole, so that the circular rubber block fixed at the end of the studs of the two butterfly fastening screws B gradually squeezes the rectangular flip plate, The rectangular overturning plate rotates at a certain angle along the rotating shaft through the cooperation with the U-shaped protrusion, so that the needle guide can better fit the surface of the patient's arm and achieve precise puncture.

Description

technical field [0001] The invention belongs to the technical field of PICC cannulation, and more particularly, particularly relates to a PICC cannulation fixing device which can increase the success rate of puncture. Background technique [0002] Peripheral venipuncture central venous catheterization (PICC catheterization) uses a catheter to puncture a vein in the peripheral arm, and the catheter reaches the large vein close to the heart, avoiding the direct contact of chemotherapy drugs with the vein in the arm, plus the blood flow of the large vein The speed is very fast, and the chemotherapy drugs can be quickly diluted to prevent the stimulation of the blood vessels by the drugs. [0003] For example, application number: CN201710260373.6 The invention discloses a multifunctional PICC tube placement operation device, comprising a support plate, two connecting plates are welded on the front and rear sides of the support plate, and the outer sides of the two connecting pla...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a PICC catheter fixation device that can increase the success rate of puncture, so as to solve the problem that the PICC catheter operator needs to fix the ultrasonic probe with one hand so that it is in contact with the patient's arm when the PICC catheter is punctured. The other hand holds the puncture needle and performs puncture along the groove of the needle guide fixedly installed on the ultrasonic probe, but this operation method is extremely inconvenient and stable. If in application, once the PICC of the ultrasonic probe is held When the intubation personnel moves the ultrasonic probe to a certain position with the hand, it will cause puncture failure due to the movement of the arm or probe during intubation, and the problem of inability to achieve accurate puncture
