Description

Front end opening type developing PICC catheter
Technical Field
The utility model relates to a medical central venous catheter who puts into through peripheral vein specifically is a front end opening type PICC pipe.
Background
Central venous Catheters (PICC) are placed via peripheral veins such as the basilic vein, the median cubital vein, and the cephalic vein, and have catheter tips located at the distal end of the superior vena cava, near the superior vena cava and deep vein catheterization at the entrance to the right atrium (Veselythmas M. Central venous catheter tip position: a connecting control [ J ]. Journal of Vascular & International Radiology,2003,14(5):527- & 534.). The technology can provide a stable venous transfusion passage, has the advantages of long retention time, small wound, safety and the like, and is widely applied to patients who need tumor chemotherapy, irritant drug infusion, parenteral nutrition and long-term venous transfusion (Wangchun, Zhang Meiying, Zhang Wanping, and the like. the reduction method of the PICC ectopic internal jugular vein is improved [ J ] China nursing journal, 2010,45 (6): 560) 561 ]. The american society for intravenous infusion care INS guidelines require that PICC navigation and tip location be confirmed by radiology or other imaging techniques before initiating infusion therapy or when clinical signs and symptoms indicate malposition. I.e., by X-ray irradiation, while simultaneously locating the in vivo walking and tip positions of the catheter in conjunction with the superior vena cava, thoracic vertebrae, and intercostals (DAVID H, NAVDEEP S, KAREN M G, et al. distance of the interventional catheter tip from the right of the interstitial tissue corrected with central [ J ]. Emerg radio, 2016, 23 (3): 269). PICC cephalic ectopy can cause severe complications such as deep vein thrombosis, arrhythmia, pericardial tamponade, etc. (Gorski L a, Hadaway L, Hagle M, et al.2016infusion compressing Standards of Practice J. Journal of infusion compressing 2016,30: S1-S159). PICC is a high-density shadow in the chest piece, and is difficult to distinguish from high-density tissues such as human bones and the like (Xuxibin, Xuyan, Yu, et al. selection and clinical application of catheter tip positioning marks on the chest piece after PICC operation [ J ]. J.J.J.Med. Imageology, 2016(9): 1612-1615.). The PICC catheter and the catheter head position in the chest radiography are accurately and quickly identified to be related to the catheter development degree, the chest radiography shooting technology, the performance of a shooting instrument, the level of a radiographer and the like, wherein the clear or not of the catheter development is particularly critical.
Currently, PICCs used clinically are classified into three-way valvular catheters and open-ended catheters according to their structural types. Due to the different structures, the two types of catheters have different trimming modes. After the three-way valve type PICC is placed in advance, the tail end of the PICC is trimmed according to the body surface measurement length of a patient; the front end open type PICC needs to be trimmed in advance according to the body surface measurement length and then placed in, the placement length of different patients is different, and the scale position of trimming is also different. The three-way valve type conduit head end is completely closed, and the surface is plated with an alloy developing marker, so that the three-way valve type conduit head can be visually identified. The most head end of the front-end opening type PICC needs to be trimmed without being wrapped by complete materials, and the original development is not as clear as that of a three-way valve type catheter; and because the pruning position needs according to actual need, can't fix a position and plate and penetrate the development marker, can't guarantee that the pipe headend end position plates and penetrates the development marker. This causes the front-end open type catheter tip to be poorly developed in the chest radiograph, and the accurate recognition of the position of the catheter tip is greatly affected.
The partial front end open type catheter can resist high pressure injection due to the material characteristics, measures the central venous pressure, and is more widely applied compared with a three-way valve type catheter. The front-end opening type catheter head end developing is realized to assist medical staff to quickly and accurately position the position of the catheter head end on the chest radiography, and more clinical requirements are met.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 and 2, the front-end opening type developing PICC catheter comprises a catheter body 101, wherein a plurality of metal developing mark rings 201 are arranged on the outer wall of the catheter body 101 at intervals. The catheter body is made of polyurethane, and the developing marking ring is plated and jetted on the outer surface of the catheter by adopting a metal material so as to enhance the developing effect.
The catheter body 101 has a head 102 at one end and a threaded connector 103 at the other end, and the catheter body 101 is provided with a thumb clamp 104 and a fixing wing 105, which may be any conventional structure.
The catheter body 101 is provided with scales, and from 0, the outer wall of the part of the catheter body 101 close to the head end 102 is provided with a plurality of metal developing mark rings 201. Starting at the 25cm mark, the development markers were looped around the catheter body at 0.2cm width for one turn at every 1.0cm interval, replacing the subsequent mark.
In this embodiment, the scale from "0" to "25 cm" on the catheter body 101: each 1cm is provided with a scale mark, and each 5cm is provided with a specific scale numerical value; from "26 cm" to the very head: every 1cm is changed into a metal marking ring, the width of the marking ring is 0.2cm, the circumference surrounds one circle of the outer diameter of the catheter, and a specific scale numerical value is still arranged every 5 cm. (see fig. 1 and 2)
In actual processing, as shown in fig. 2, a developing mark ring made of nickel titanium (nickel, titanium or respective alloys) is plated on the surface of the PICC catheter body from 25cm scale at intervals of 1cm until the most end of the catheter. The mark ring development of nickel titanium or respective alloy material is highlighted white in the chest piece, and peripheral tissue development is darker, can distinguish directly perceivedly to help medical personnel to discern PICC pipe head position fast accurately.
When the catheter is used, the cutting length of the catheter body is determined according to the body surface measurement value of a user.
