Abstract
A deep vein catheter device comprises a catheter, a connecting piece, an extension pipe, a clamping piece, an extension pipe holder and a heparin cap. Three or above cavities are formed in the catheter, at least a side hole is formed on the outer side wall of a side cavity of the catheter, and the catheter is made of polyurethane material. The catheter is provided with a multi-cavity structure, and the number of the cavities can be changed according to the clinical application requirement to fully meet the present and future clinical requirements; since the catheter is made of the material of which the rigidity varies along with temperature, the catheter is rigid under ordinary temperature to facilitate catheterization and is very soft after entering human body. The pointed end of the catheter is made of peculiar polyurethane material and treated through softening, so as to avoid the damage of blood vessels during catheterization to the maximum extent.
Description
Affiliated technical field
This utility model relates to a kind of dark venous duct device, particularly uses the conduit of a kind of multi-cavity and variable hardness.Belong to technical field of medical instruments.
Background technology
At present dark venous duct is widely used, as continuing with discontinuity venous transfusion, monitoring center's vein pressure, the outer central vein nutrition of full intestinal, the infusion height oozes or irritating solution, blood transfusion or blood products, collecting blood sample etc. for heavy patient and major operation patient.Existing central venous catheter is generally single chamber and two-chamber, and when at the two or more medicines that incompatibility is arranged of input, or when implementing the various clinical monitoring means simultaneously, single chamber and double channel catheter can not satisfy the demands fully.In addition, existing tube material is based on silica gel and polyethylene, polypropylene, polrvinyl chloride, but shortcoming is respectively arranged.Silica gel is a kind of very softish material, causes putting pipe process difficulty, even may cause putting tube failure delay treatment opportunity.Polyethylene, polypropylene, polrvinyl chloride are the harder materials of a class, put pipe easily, but when putting pipe and being trapped in the indwelling process of blood vessel, particularly to the infant patient, may damage even run through blood vessel, cause that hemothorax jeopardizes patient health even life.
Summary of the invention
Insufficient in order to overcome the catheter lumen number, and conduit is really up to the mark or soft excessively shortcoming.This utility model provides a kind of dark venous duct device, this dark venous duct device uses the above conduit in three chambeies or three chambeies, wherein conduit has certain degree of hardness to be easy to put pipe under room temperature (23 ℃ ± 2 ℃), put and insert human body parts behind the pipe and become very soft when being increased to body temperature (37 ℃ ± 1 ℃), fabulous with the compatibility of blood vessel.
The technical scheme that its technical problem that solves this utility model adopts is:
Pipe guide is made up of conduit, connector, extension pipe, intermediate plate, extension tube socket, calparine cap.Be provided with the chamber more than three or three in the conduit, be divided into a main chamber and 2-4 side chamber, the outlet of main chamber is catheter tip, the outlet of side chamber on duct wall side opening and seal at the tip.Be connected with connector in the conduit other end, conduit is connected with side chamber extension pipe with main chamber extension pipe respectively by connector.Main, side chamber extension Guan Yiduan respectively is connected with the extension tube socket, and the extension tube socket seals with calparine cap.
At least have a side opening on the lateral wall in conduit side chamber, and be evenly distributed near the catheter tip place.
Conduit is respectively equipped with intermediate plate being provided with fixation clamp near the connector position on master, side chamber extension pipe.
Conduit is made by polyurethane material, and the hardness of this material is with variable temperatures.Catheter tip materials is littler, more soft than the hardness of body.
The beneficial effects of the utility model are: conduit has multi-cavity structure, and the chamber number can change with clinical practice, fully satisfies at present and following clinical demand; Conduit adopts hardness to make with the material of variable temperatures, presents hard under the room temperature and is beneficial to and puts pipe, becomes very soft after entering in the body.Special polyurethane material is used at the tip of conduit, exquisite slick conduit head end, welding forming, and surperficial superslide is handled, and conduit is inserted in the blood vessel be more prone to, safety.And with the most advanced and sophisticated soft head of conduit integrated design, handle, can farthest avoid in the intubate process damage blood vessel through softening.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the catheter tip partial enlarged drawing.
Fig. 3 is the sectional view of three chambeies and four cavities conduit pipes.
1. conduits among the figure, 2. connector, 3. extension pipe, 4. intermediate plate, 5. extension tube socket, 6. calparine cap, 7. tip, 8. side opening, 9. main chamber, 10. side chamber.
The specific embodiment
Below in conjunction with description of drawings performance of the present utility model, but they do not constitute qualification of the present utility model, only do for example.As shown in Figure 1 and Figure 2.
Be provided with three chambeies in the conduit 1, be divided into a main chamber 9 and 2 side chambeies 10,9 outlets of main chamber are catheter tip 7, side opening 8 and at tip 7 sealings of side chamber 10 outlets on conduit 1 tube wall.Conduit 1 other end is connected with connector 2, and conduit 1 is connected with side chamber extension pipe with main chamber extension pipe 3 respectively by connector 2.Each extension pipe other end of main chamber and side chamber respectively is connected with extension tube socket 5,6 sealings of extension tube socket 5 usefulness calparine caps.
Conduit 1 also can be designed to comprise the structure of a plurality of chambers.For example three chambeies and four chambeies.As shown in Figure 3.
Claims (2)
1. dark venous duct device, by conduit, connector, the extension pipe, intermediate plate, the extension tube socket, calparine cap is formed, it is characterized in that: be provided with the chamber more than three or three in the conduit, be divided into a main chamber and 2-4 side chamber, the outlet of main chamber is catheter tip, side chamber outlet on duct wall side opening and seal at the tip, be connected with connector in the conduit other end, conduit is connected with side chamber extension pipe with main chamber extension pipe respectively by connector, main, side chamber extension Guan Yiduan respectively is connected with the extension tube socket, the extension tube socket seals with calparine cap, at least have a side opening on the lateral wall in conduit side chamber, and be evenly distributed near the catheter tip place, conduit is being provided with fixation clamp near the connector position, in the master, be respectively equipped with intermediate plate on the extension pipe of side chamber.
2. dark venous duct device according to claim 1 is characterized in that: conduit is by the polyurethane manufacturing, and catheter tip is littler, more soft than the hardness of body.
