Pre-negative pressure suction type deep artery and venous silk-guiding introducing device

Abstract

The invention relates to a deep arteriovenous guide-wire posting-implement of the pre-negative-pressure pumping type. The prior domestic and oversea vein-posting technologies have the problems that the accuracy of the puncture is not high; the operation difficulty is great; the medicinal personnel can difficultly grasp the technology; at the same time the patient suffers the pain of damnification. The purpose of the invention is to design a deep arteriovenous guide-wire posting-implement of the pre-negative-pressure pumping type which has good puncture effect, high accuracy and simple operation and can automatically exsanguinated. The device consists of four parts of a pinhead, a pinhead connecting sleeve, a piston sleeve and a piston inside-core. The device adopts the automatic negative-pressure pumping type to arrange a negative-pressure switch at the puncture pinhead connecting sleeve and arrange a spring plate lock at an aspirator inside-core to ensure that the negative pressure is formed inside the piston. The invention is design reasonably and is provided with the good accuracy and the good effect of the automatic pumping.

Description

Technical field: [0001] The invention belongs to medical appliances, in particular to a pre-negative pressure suction type deep arteriovenous guidewire inserter. Background technique: [0002] The existing venous catheter insertion technology at home and abroad generally has low puncture accuracy, great damage to patients, many complications, not long enough catheter insertion time, difficult operation, and difficult to master, so the popularity rate is not high, so that It is difficult for most of the medical staff to master this technology, which also increases the suffering of the patient and affects the timing of the patient's treatment. Invention content: [0003] The object of the present invention is to provide a pre-negative pressure suction type deep arteriovenous guide wire inserter which is easy to operate, high in accuracy and strong in aseptic operability based on the above disadvantages. It can automatically draw blood, can complete puncture suction with one...
