Cervical gear for automatically blocking internal jugular vein blood flow for peripherally inserted central catheter (PICC) puncture

Abstract

The invention discloses a cervical gear for automatically blocking internal jugular vein blood flow for peripherally inserted central catheter (PICC)puncture. The cervical gear includes a first support plate, a driving box, a micro air pump, and a detection component,a second support plate is arrangedon the inner side of the first support plate, hinges are mounted below the left and right sides ofthe first support plate correspondingly, fixing rodsare connected below the hinges, support plates aremounted below the fixing rods,the driving box is arranged on the front surface of the support plate, and a pressure plate is embedded to theinner side of the support plate. The cervical gearfits to the neck of a patient, the comfort effect is high, the overall structure is simple, wearing of thecervical gearis convenient,the operation is convenient, the second support plate can be rotated with respect to the first support plate, the automatic head turning operation of the patient is then realized, the problemthata medical staff is needed to assist the patient to turn the head in the prior art is solved, the burden of the medical staff is advantageously reduced, and the pressure plate canrealize automatic compression of the internal jugular vein of the patient, the problem thatthe medical staff is needed to perform the pressing operation in the prior art is solved,and practicality ishigh.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a neck collar for automatically blocking internal jugular vein blood flow for PICC puncture. Background technique [0002] PICC is the English abbreviation for Peripherally Inserted Central Catheter. PICC technology is a method of sending a peripheral central catheter from the cubital fossa vein along the blood vessel to the superior vena cava (SVC). It has developed into a convenient, effective, and Safe catheterization technique. When PICC catheterization is performed, it is performed in the order of basilic vein-axillary vein-subclavian vein-superior vena cava. If a fork is taken halfway, it will be from the subclavian vein to the internal jugular vein. Therefore, clinically Generally, two methods are used to prevent the occurrence of this kind of pain. The first method is the head tilt method: when the catheter is inserted, the patient is placed in a supine position....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a PICC puncture neck collar that can automatically block the blood flow of the internal jugular vein, which solves the existing clinical problems for comatose patients, whether it is using the head tilt method or the finger pressure type internal jugular vein. The blocking method requires medical staff to assist the patient to complete the head tilt or press action, which increases the burden on the medical staff to a certain extent.
