Abstract

The utility model discloses a positive-pressure needleless connection type peripherally inserted central catheter, which comprises a needleless infusion joint and an indwelling catheter. The needleless infusion joint is hermetically connected with the indwelling catheter, the needleless infusion joint is a positive-pressure needleless infusion joint, and the indwelling catheter is provided with a plurality of H-shaped incisions. When the positive-pressure needleless infusion joint is used for infusion or return blood drawing, the H-shaped incisions of the indwelling catheter can be concave and convex outwards or inwards. When an infusion set is pulled out after infusion of liquid medicines, the positive-pressure needleless infusion joint can generate positive pressure for pushing the liquid medicines ahead to prevent blood reflux from generating thrombi, blockage of the indwelling catheter can be effectively avoided, and the indwelling time of the indwelling catheter is prolonged.

Description

Malleation needleless interconnection system peripheral vein is inserted central venous catheter
Technical field
this utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of malleation needleless interconnection system peripheral vein and inserts central venous catheter.
Background technology
are present; It is ripe as the technology of the path of detection in the art, blood transfusion, fluid infusion that peripheral vein on the market is inserted central venous catheter, obtained popularizing, but also coming out progressively of many problems; Wherein the most key problem is that central venous catheter is after patient's intracorporeal indwelling a period of time; Clot cellulose thrombosis or drug precipitation are stopped up conduit, influence the normal use of central venous catheter, can only change.Both increase puncture and made the patient suffering, increased medical personnel's workload and patient's cost again.
Summary of the invention
this utility model purpose is: in order to overcome above-mentioned technical problem, this utility model provides a kind of and can produce peripheral vein malleation, that can avoid stopping up automatically and insert central venous catheter.
The technical scheme of this utility model is: a kind of malleation needleless interconnection system peripheral vein is inserted central venous catheter; Comprise needleless infusion connector and inlying catheter; Above-mentioned needleless infusion connector and inlying catheter are tightly connected, and said needleless infusion connector is a malleation needleless infusion connector.When the infusion utensil was extracted in the completion of infusion medicinal liquid, malleation needleless infusion connector can produce malleation, medicinal liquid was pushed ahead stop the blood backflow to produce thrombosis, can effectively avoid the indwelling time of inlying catheter obstruction and prolongation inlying catheter.
said malleation needleless infusion connector can be through-type malleation needleless infusion connector, also can be triplet type malleation needleless infusion connector.If malleation needleless infusion connector is a triplet type malleation needleless infusion connector, also can be provided with the end cap that to puncture on its side pipe.
Offer several I-shaped joint-cuttings on said inlying catheter wall; I-shaped joint-cutting on the said inlying catheter wall comprises two transverse parts that laterally arrange; And being connected in the longitudinal part between this two transverse part, the longitudinal part of said I-shaped joint-cutting extends axially along inlying catheter.Above-mentioned I-shaped joint-cutting is in the natural enclosing state when not infusing and do not draw back blood.When infusing through malleation needleless infusion connector or drawing back blood, I-shaped conduit joint-cutting can the outside or inside concavo-convex infusion medicinal liquid that makes things convenient for.I-shaped kerf structure can depart to inside and outside than single in-line joint-cutting and cross joint-cutting more, and reset capability is stronger.
The utility model has the advantages that:
1. this utility model have avoided patient to change twice puncture that causes because of inlying catheter stops up, and the malleation of generation can prevent that more the blood backflow from producing thrombosis, can effectively avoid inlying catheter to stop up and prolong the indwelling time of inlying catheter.
. the I-shaped joint-cutting in this utility model on the inlying catheter wall can serve as two way valve; I-shaped joint-cutting is in the natural enclosing state when not infusing and do not draw back blood, when infusing through malleation needleless infusion connector or drawing back blood; Outside or the inside concavo-convex infusion medicinal liquid that makes things convenient for of I-shaped conduit joint-cutting meeting; And I-shaped kerf structure, can depart to inside and outside more than single in-line joint-cutting and cross joint-cutting, reset capability is stronger.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further described:
Fig. 1 is a kind of structural representation of this utility model;
Fig. 2 is the another kind of structural representation of this utility model;
Fig. 3 is the transfusion state of inlying catheter I-shape construction in this utility model;
Fig. 4 is the blood state of drawing back of inlying catheter I-shape construction in this utility model.
wherein: 1 needleless infusion connector; The through-type malleation needleless of 1a infusion connector; 1b triplet type malleation needleless infusion connector; 2 inlying catheters; 3 I-shaped joint-cuttings; The 3a transverse part; The 3b longitudinal part; 4 end caps that can puncture.
The specific embodiment
embodiment 1: as shown in Figure 1; A kind of malleation needleless interconnection system peripheral vein is inserted central venous catheter; Comprise needleless infusion connector 1 and inlying catheter 2; Above-mentioned needleless infusion connector 1 is tightly connected with inlying catheter 2, and said needleless infusion connector 1 is through-type malleation needleless infusion connector 1a.
embodiment 2: as shown in Figure 2; A kind of malleation needleless interconnection system peripheral vein is inserted central venous catheter; Comprise needleless infusion connector 1 and inlying catheter 2; Above-mentioned needleless infusion connector 1 is tightly connected with inlying catheter 2, and said needleless infusion connector 1 is triplet type malleation needleless infusion connector 1b, also can be provided with the end cap 4 that can puncture on its side pipe.
When above-mentioned two embodiment extract the infusion utensil in the completion of infusion medicinal liquid; Malleation needleless infusion connector 1a, 1b can produce malleation; Medicinal liquid is pushed ahead the backflow of prevention blood produce thrombosis, can effectively avoid inlying catheter 2 to stop up and prolong the indwelling time of inlying catheter 2.Because malleation needleless infusion connector 1a, 1b are prior art, and its structure is various, so present embodiment is not elaborated to its concrete structure.
among the foregoing description 1 and the embodiment 2, offer several I-shaped joint-cuttings 3 like Fig. 3, shown in 4 on the said inlying catheter wall 2.Said I-shaped joint-cutting 3 comprises the two transverse part 3a that laterally arrange, and is connected in the longitudinal part 3b between this two transverse part 3a, and the longitudinal part 3b of said I-shaped joint-cutting 3 extends axially along inlying catheter 2.Above-mentioned I-shaped joint-cutting 3 can serve as two way valve, and when transfusion, I-shaped joint-cutting 3 outwards departs from; When drawing back blood, I-shaped joint-cutting 3 departs from inwards; Do not infuse when not drawing back blood, I-shaped joint-cutting 3 is in the natural enclosing state.I-shaped joint-cutting 3 structures can depart to inside and outside than single in-line joint-cutting and cross joint-cutting more, and reset capability is stronger, can avoid clot, cellulose thrombosis or medicinal liquid precipitate etc. in the cohesion of conduit periphery preferably, prevent that inlying catheter from stopping up.
Only be the concrete exemplary applications of this utility model more than , the protection domain of this utility model is not constituted any limitation.Except that the foregoing description, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
