Abstract

The utility model relates to the technical field of medical instruments, and concretely relates to a disposable central venous puncture bag. At present, in the process of tube placing for domestic venous transfusion, after a puncture needle punctures in a central vein, a guide steel wire is placed firstly, then the puncture needle is withdrawn, a skin expansion operation is performed by using a skin expander, and then a central venous catheter is placed along the guide steel wire. The defects are as follows: 1, the guide steel wire can touch the heart, thereby causing arrhythmia; 2, the skin expansion operation performed by using the skin expander possibly causes that the guide steel wire is bent and the catheter is difficult to implant, thereby causing puncture failure; and 3, the catheter is coarser, and the associated infection probability of the central venous catheter is large. The disposable central venous puncture bag disclosed by the utility model is composed of a central venous catheter and a puncture needle, wherein a catheter sheath is arranged on the outside of the puncture needle, and the catheter sheath is provided with an easily-torn fracture indentation. When the puncture bag is used, the central venous catheter is placed in from the inside of the catheter sheath. The puncture bag is simple in operation, no guide steel wire is provided, and no skin expansion is required to be performed, thereby easing the trauma to the patients to a certain extent, and also reducing the occurrence rate of catheter related infections.

Description

Disposable central venous puncture bag
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of disposable central venous puncture bag.
Background technology
What adopt when at present, domestic venous transfusion is put pipe is the Seldinger method: puncture needle is first placed guide wire after penetrating central vein, then withdraws from puncture needle, expands skin with skin dilator, then puts into central venous catheter along guide wire.The shortcoming of the method is: 1, as putting into guide wire along puncture needle when long, guide wire may touch heart, very likely causes arrhythmia.2, need to expand skin along guide wire application skins based upon bidding dilator, when as relatively poor in puncture personnel technology, very likely cause guide wire crooked, conduit is inserted difficulty, thus puncture failure.3, conduit is thicker, and the central venous catheter-related infection probability is large.
Summary of the invention
The purpose of this utility model is to want to provide a kind of central vein puncture needle, can effectively solve the defective of above-mentioned prior art.
This utility model adopt technical scheme formed by central venous catheter and puncture needle; There is a conduit epitheca puncture needle outside, and respectively there is the fracture impression of an easily openable conduit epitheca both sides or has both sides that the easy tear tape of fracture impression is arranged on the conduit epitheca; The central venous catheter afterbody has two to advance the medicine connector.
Further, conduit epitheca length is for being not less than 7cm, and internal diameter is 2.2 mm, and central venous catheter length is not less than 22 cm, and external diameter is 2mm.
The beneficial effects of the utility model are: 1, without guide wire, need not to expand skin, alleviated to a certain extent the wound to patient, also reduced the incidence rate of catheter associated infection.2, insert from peelable conduit epitheca because of central venous catheter, during the design conduit, comparable present conduit diameter is thin, also need not the hardness of present conduit, and namely conduit diameter is thin, soft, thereby improved patient's comfort level, reduced to a certain extent the incidence rate of catheter associated infection.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the puncture needle structure schematic diagram;
Fig. 3 is that embodiment 1 puncture needle conduit epitheca is torn view;
Fig. 4 is that the puncture needle conduit epitheca of embodiment 2 is torn view.
The specific embodiment
In figure: 1. central venous catheter, 2. puncture needle, 3. conduit epitheca.
Embodiment 1
As can be known, formed by central venous catheter 1 and puncture needle 2 from Fig. 1, Fig. 2, Fig. 3; There is a conduit epitheca 3 the puncture needle outside, respectively there is the fracture impression of an easily openable conduit epitheca 3 both sides. and conduit epitheca 3 length are for being not less than 7cm, and internal diameter is 2.2 mm, and central venous catheter length is not less than 22 cm, external diameter is 2mm, and afterbody has two to advance the medicine connector.The conduit epitheca is made by the higher medical apparatus and instruments plastics of hardness.
Embodiment 2
As can be known from Fig. 4, the present embodiment has both sides that the easy tear tape of fracture impression is arranged as different from Example 1 on the conduit epitheca.
During use, when puncture needle was thrust vein, its outside conduit epitheca penetrates into intravenous simultaneously, and (prior art can realize.), then withdrawing from puncture needle, central venous catheter is inserted in the conduit epitheca, then the conduit epitheca is withdrawed from along central venous catheter, tears, takes off from the fracture impression, as shown in Figure 2.Namely complete venous transfusion and put pipe.
Obviously, above-described embodiment of the present utility model is only for this utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
