Abstract

The utility model provides a double-cavity lateral ventricle extracorporal drainage catheter belonging to a medical instrument. The drainage catheter is provided with a tube body, the rear end of the tube body is sealed, and the rear of the tube body is provided with an outlet hole communicated with the inner cavity of the tube body. The front end of the tube body is provided with a tube opening, and a thin tube is also connected to the front part of the tube body. The inner cavity of the thin tube is communicated with a wall interior tube cavity in the tube wall of the tube body, the rear end of a liquid hole is another outlet hole, and the front end of the thin tube is another tube opening. The drainage catheter has the advantages of reasonable structure, low manufacture difficulty and low production cost. The space of the thin tube inner cavity and the wall interior tube cavity is small, so little liquid medicine is trapped in the space after the liquid medicine is transfused by the thin tube inner cavity and the wall interior tube cavity. Drug waste is avoided, and curative effect is ensured.

Description

Two-chamber body of lateral ventricle drainage tube

Technical field

This utility model provides a kind of medical apparatus, the utensil that especially a kind of tricorn drain is used.

Background technology

At present, when carrying out the body of lateral ventricle external drainage, used drainage tube is the drainage tube in single chamber.When injecting medicine, directly prick the side of tube wall, the phenomenon of leakage easily takes place in operation inconvenience, can cause retrograde infection.When the flushing ventricles of the brain, need insert the drainage tube in two single chambeies in patient head, one is injected the flushing medicine, and another extracts flushing liquor out, and like this, not only complex operation is also bigger to patient's infringement.The China Patent No. that the applicant obtains is that " the two-chamber brain side room external drainage pipe " of ZL200720021586.5 adopts double cavity structure, form by interior pipe and outer tube, solved this problem, but the manufacture difficulty of its structure is big, and production cost is higher, and the space between the inner and outer pipes is big, behind the input of the space between inner and outer pipes medicine, have more medicine and be trapped in this space, both caused the more waste of medicine, influenced curative effect again.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of two-chamber body of lateral ventricle drainage tube is provided, and it is easy to make, and reduces the waste of medicine.

This utility model is to realize like this, two-chamber body of lateral ventricle drainage tube, it has body, the body back-end closure, there is the outlet opening that communicates with tube cavity at the rear portion of body, and the body front end has the mouth of pipe, also be connected with tubule in the body front portion, tube chamber is connected in the wall in the tube wall of tubule inner chamber and body, and the rear end in liquid hole is another outlet opening, and the front end of tubule has another mouth of pipe.

Adopt the two-chamber body of lateral ventricle drainage tube of said structure, rational in infrastructure, manufacture difficulty is low, production cost is lower, and luminal space is little in tubule inner chamber, the wall, behind tube chamber input medicine in tubule inner chamber, the wall, does not have too many medicine and is trapped in this space, both avoid the waste of medicine, guaranteed curative effect again.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.

As shown in drawings, the two-chamber body of lateral ventricle drainage tube of this utility model, it has body 13, body back-end closure, the rear portion of body have the outlet opening 19 that communicates with tube cavity, and the body front end has the mouth of pipe 18, also be connected with tubule 14 in the body front portion, tube chamber 12 is connected in the wall in the tube wall 20 of tubule inner chamber and body, and the rear end in liquid hole is another outlet opening 11, and the front end of tubule has another mouth of pipe 15.

In the described mouth of pipe 18, rubber stopper 17 is arranged, another rubber stopper 16 is arranged in another mouth of pipe 15.

After this drainage tube is inserted into the patient-side ventricles of the brain, syringe needle can be passed the rubber stopper in another mouth of pipe 15, carry out the injection of medicine, the medicine of injection enters tube chamber 12 in the wall, flows out through another outlet opening 11.Washing, during drain, can inject through another mouth of pipe 15 by the flushing medicine, the flushing liquor in the brain etc. enters tube cavity through outlet opening 19, flows out from the mouth of pipe 18.The method that this drainage tube is inserted into the patient-side ventricles of the brain is identical with existing single chamber drainage tube.

As shown in Figure 1, on existing two-chamber body of lateral ventricle drainage tube, the body 8 that is made of the interior pipe 3 in outer tube 2, the outer tube is arranged, there is plug 10 body the inner, the body outer end has and outer tube, interior pipe between the mouth of pipe 4 of intracavity inter-connection, another mouth of pipe 7 that communicates with interior tube cavity has the outlet opening 1 that only communicates with interior tube cavity in body the inner in addition, only have on the outer tube of body the inner with outer tube, interior pipe between another outlet opening 9 of communicating of inner chamber.In the described mouth of pipe 4, rubber stopper 5 is arranged, another rubber stopper 6 is arranged in another mouth of pipe 7.
