Abstract
The utility model relates to a medical device, particularly to an injection needle which is provided with a needle tube assembly which is composed of a needle tube 1 and a needle tube base 2. The utility model is characterized in that a sleeve pipe assembly is formed by the connection of a trocar pipe 3 and a trocar base 4, and the sleeve pipe assembly is sheathed on the needle tube assembly. The utility model is provided with a base plunger 5 which is plunged on a sleeve pipe base, the top of the trocar pipe 3 forms a conical shape, and is close attached to the surface of the needle tube 1. The utility model has the advantages that the structure is reasonable, the utility model can be left in a blood vessel for a long time after punctured once, relieve the pain of patients, and relieve nursing work amount when the utility model is used for continuous injection, infusion, blood transfusion, etc.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of entry needle.
Background technology
Existing entry needle needs needs of patients such as transfusion, blood transfusion and chemotherapy of tumors injection, long-term nutrition transfusion repeatedly to puncture to continuing, even need carry out venesection to the critical patient, causes patient painful big, and nursing work load is also big.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the shortcoming that exists in the prior art, provides a kind of mechanism reasonable, pin can be kept somewhere in blood vessel, can carry out continuous several times transfusion and the entry needle that need not repeatedly to puncture.
This utility model is achieved in that a kind of entry needle for this reason, by the needle tubing assembly of forming by needle tubing, needle tubing seat, it is characterized in that: a cover pipe assembly that is connected to form by trocar tube and trocar base is arranged, the cover pipe assembly is sleeved on the needle tubing assembly, other has one to be used to fill in the seat plug that is contained on the casing seat, the end of trocar tube is tapered, is close to the needle tubing surface.
The beneficial effects of the utility model are: rational in infrastructure, only need carry out one-time puncture, and can be retained in for a long time in the blood vessel, be used for continuous injection, transfusion, blood transfusion etc., both can reduce patient's misery, alleviated nursing work load again.
Description of drawings
Accompanying drawing is this utility model decomposition texture sketch map.
Among the figure: 1. 5. plugs of needle tubing 2. needle tubing seat 3. trocar tubes, 4. trocar bases.
The specific embodiment
With reference to the accompanying drawings, a kind of entry needle, by the needle tubing assembly of forming by needle tubing 1, needle tubing seat 2, it is characterized in that: a cover pipe assembly that is connected to form by trocar tube 3 and trocar base 4 is arranged, the cover pipe assembly is sleeved on the needle tubing assembly, other has one to be used to fill in the seat plug 5 that is contained on the casing seat, and the end of trocar tube 3 is tapered, is close to needle tubing 1 surface.
Using method: during injection, trocar tube 3 thrusts in the blood vessel in company with needle tubing 1 together, subsequently the needle tubing assembly is extracted, trocar tube 3 is stayed in the blood vessel, and trocar tube seat 4 is linked to each other with syringe adapter, gets final product liquid medicine injection, injection finishes, only need to entangle needle tubing seat 2, and trocar tube 3 still stays in blood vessel, for future use with seat plug 5.
