Description
Изобретение относитс к медицине кой техцике, а именно к устройствам дл введени катетеров в организм пациента.The invention relates to medical techie, in particular to devices for inserting catheters into the patient's body.
Известна игла дл .введени катетера , содержаща полую изогнутую трубку со CKomeHHfciM острым рабочим концом 1.A known needle for insertion of a catheter containing a hollow bent tube with a CKomeHHfciM sharp working end 1.
При введении такой иглы, проколота ею рана имеет в поперечном сечении круглую форму, что создает неблагопри тные услови заживлени травмируемых тканей, вследствие того, что поверхность их контакта мало развита .With the introduction of such a needle, the wound punctured by it has a circular shape in cross section, which creates unfavorable conditions for the healing of injured tissues, due to the fact that the surface of their contact is poorly developed.
Цель.изобретени - сокращение сроков заживлени раны.The purpose of the invention is to reduce the time of wound healing.
Поставленнс1Я цель достигаетс тем, что в игле дл введени катетера , состо щей из изогнутой полой трубки со скошенным острым рабочим концом, рабочий конец вьшолнен в виде ромба с режущими кромками в его вершинах.The goal is achieved by the fact that in the needle for inserting a catheter, consisting of a curved hollow tube with a beveled sharp working tip, the working end is completed in the form of a diamond with cutting edges at its tips.
На фиг. 1 изобра хен катетер, вид сбоку; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 image hen catheter, side view; in fig. 2 is a section A-A in FIG. one.
, Игла выполнена в виде полой изогнутой трубки 1 со скошенным острым рабочим концом 2, содержащим режуThe needle is made in the form of a hollow curved tube 1 with a bevelled sharp working end 2 containing a cutting
щие кромки 3, наход щиес в вершьнах ромба.edges 3, located in a diamond.
При введении иглы острие рабочего конца 2 направл ют перпендикул рно месту вкола. -После введени иглы через ее полость в организм ввод т катетер. Зафиксировав его в требуемом положении, удал ют иглу.When inserting the needle, the tip of the working end 2 is directed perpendicular to the site of puncture. - After inserting the needle, a catheter is inserted through the body cavity. By fixing it in position, the needle is removed.
При вводе иглы образуетс рана, When the needle is inserted, a wound is formed,
10 имеюща в поперечном сечении крестообразную форму, что создает благопри тные услови дл ее заживлени путём обеспечени поверхностей взаимного контакта, на которых интенси15 фицируетс процесс срастани тканей.10 is a cross-shaped cross-section, which creates favorable conditions for its healing by providing mutual contact surfaces on which the process of tissue adhesion is intensified.
