Abstract
The utility model discloses a PICC internally-arranged pipe body externally-strengthening joint which comprises a plastic soft needle, a taper joint, a fixing interface and a steel needle. The taper joint is set to be in a conical shape, a reinforcing portion is arranged on the taper joint backwards, and a clamping groove is formed in the reinforcing portion. Due to the fact that the structure of the reinforcing portion is arranged on the taper joint, a PICC internally-arranged pipe body can be prevented from exiting out of the human body; due to the fact that the taper joint is arranged, the probability of fractures of the plastic soft needle is reduced, the fixing interface is set to be an inwardly-spiral interface, and the fixing interface can be connected with a positive pressure joint, and can also be connected with medical joints such as a heparin cap; a steel needle cap is in the externally-spiral shape and is connected with the fixing interface in a meshed mode, meanwhile a syringe needle is matched with the inner wall of the plastic soft needle, the plastic soft needle and a PICC pipe are of the same type, and the plastic soft needle is put into the PICC pipe in the mode that the steel needle moves forwards and backwards.
Description
Technical field
This utility model relates to medical field, particularly the external enhancing joint of a kind of PICC built-in pipe.
Background technology
The existing built-in body of clinical use PICC is the important means of patient infusion chemotherapy, but transfusion chemotherapy has the intermission, patient will go home to have a rest during this period, the built-in body of existing PICC is after the use of half a year, the built-in body of PICC tends to cause external flexible pipe to occur the situation of fracture because often move the situations such as bending in use procedure, itself put pipe expense very high, the rear tube drawing of fracture and again intubate can be brought misery to patient, and have increased medical expense.Sometimes PICC pipe can withdraw in human body, to patient, brings certain misery and trouble.
Utility model content
For solving the problem existing in above-mentioned background technology, the purpose of this utility model is to provide the enhancing joint outside a kind of PICC body, with reach prevent the fracture of the built-in body of PICC and prevent that the built-in body of PICC from withdrawing in human body or by this joint can perfect aspect the object of disconnected pipe reparation.
For achieving the above object, the technical solution of the utility model is as follows:
The external enhancing joint of PICC built-in pipe, comprises the soft pin of plastics, taper joint, fixed interface and draw point, it is characterized in that, described taper joint is set to taper shape, in described taper joint, is provided with rib, and it is inner that described draw point is placed in human body outer tube body.
Preferably, on described rib, be provided with draw-in groove.
Preferably, described anchor tip is internal coiling shape.
Preferably, described draw point pin cap is external spiral shape, be connected with anchor tip, and the soft pin inwall laminating of draw point and plastics.
Preferably, the soft pin of described plastics is identical with PICC pipe model.
Pass through technique scheme, the external enhancing joint of a kind of PICC built-in pipe that this utility model provides, by taper joint, be set to the probability that taper shape has reduced the soft pin fractures of plastics, by the rubbing surface that can increase tube for transfusion and human body that arranges of rib, effectively avoid tube for transfusion to be drawn out of in body, by anchor tip is set, be that internal coiling straight coupling can make this joint both can connect positive pressure connector, also can connect the conventional medical connectors such as calparine cap, by draw point pin cap, it is external spiral shape, be connected with anchor tip, the soft pin inwall laminating of draw point and plastics, the soft pin of plastics is identical with PICC pipe model, the mode of moving back while entering by draw point can be sent into the soft pin of plastics in PICC pipe, complete the effect of planting pipe or repairing.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the perspective view of the external enhancing joint of the disclosed a kind of PICC built-in pipe of this utility model embodiment;
Fig. 2 is the perspective view of the rib of the external enhancing joint of the disclosed a kind of PICC built-in pipe of this utility model embodiment;
In figure, number designation represents the title of parts:
1, the soft pin of plastics; 2, taper joint; 3, rib; 4, draw point; 5, draw point pin cap; 6, anchor tip; 7, draw-in groove.
The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
The external enhancing joint of a kind of PICC built-in pipe that this utility model provides, as shown in Figure 1-2, comprises the soft pin 1 of plastics, taper joint 2, rib 3, draw point 4, draw point pin cap 5, anchor tip 6.Draw point pin cap 5 is external spiral shape, is connected with anchor tip.Taper joint 2 is set to the conical probability that can reduce so soft pin 1 fracture of plastics; Rib 3 is set in taper joint 2; On rib 3, be provided with draw-in groove 7; Such structure can strengthen the frictional force of medical adhesive tape and the external enhancing joint of PICC built-in pipe, makes to paste more firm; Anchor tip 6 is set to internal coiling shape, both can connect positive pressure connector, also can connect the conventional medical connectors such as calparine cap; Soft pin 1 inwall of draw point 4 syringe needles and plastics coincide, and the mode of moving back while entering by draw point can be sent into the soft pin of plastics in PICC pipe, completes the effect of planting pipe or repairing.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use this utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, this utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (5)
