Abstract
The utility model relates to a medical connector belonging to the field of medical apparatus, which comprises a tube-shaped hollow valve with male thread on both ends, a revolving joint, a revolving cap, a support tube and a silica gasket. The revolving joint is a pipe joint, comprising an inner end of the female thread connecting with one end of the valve and an outer end of the female thread connecting with an external connecting part, the inside diameter of the outer end is greater than that of the inner end. The revolving cap is a hollow cylinder, one end of which with smaller inside diameter is fixedly connected with the tube-shaped valve, the other end with inside diameter greater than that of the valve is equipped with thread on the inner surface. The silica gasket is disposed into the valve at the joint of the revolving cap. The support tube is obliquely disposed in the valve and communicated with the valve, with mouth scattered with thread on the edge. The structure mentioned above has fully realized blood leakage protection during intervening operations and transferring various drugs into blood vessels of patients.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of intervene operation medical apparatus and instruments adapter.
Background technology
In the interventional therapy method of cardiovascular disease, need regular ground constantly some insertings or liquid to be transported in the patient body.For example, on patient's blood vessel, cut a less relatively otch, conduit is got involved wherein, the doctor can be by this intervention the staying an external end and will treat support that the liquid of usefulness maybe need get involved and transport to and need the place that arrives in the blood vessel of conduit, and, by this catheter end, the sample that can get patient repeatedly is used for chemical examination, also can undergo surgery by this catheter end and detect.In operation, often different detecting instruments or different treatment medicines need be connected to catheter end, thereby need a plurality of such catheter ports.Another problem of running in operation is to have oozing of blood in patient's blood vessel incision and the junction of getting involved the conduit in it.We provide a kind of adapter can solve above-mentioned oozing of blood better and multiport is connected to the interior problem of patient's blood vessel.
Summary of the invention
The adapter that is used for intervene operation that prevents the oozing of blood function that provides a kind of tool outstanding is provided the purpose of this utility model.
Realize that this utility model purpose technical scheme is: a kind of medical connector, it comprises the externally threaded hollow tubular valve body of two tool, swivel joint, a spiral cover and an arm wherein, also comprise a silica gel pad.Above-mentioned swivel joint is a pipe joint, and the outer end of the tool female thread that is connected with joint outer part is treated in the inner end and that it has a female thread that is connected with an end of tubular valve body, and the internal diameter of above-mentioned outer end is greater than the internal diameter of inner end; Above-mentioned spiral cover is a hollow cylinder, the part that this cylinder one end internal diameter is little closely is connected with above-mentioned tubular valve body, other end internal diameter has screw thread greater than the part inner surface of above-mentioned valve block internal diameter, lays silica gel pad in the valve body of above-mentioned spiral cover and tubular valve body connecting portion; Above-mentioned arm is arranged on above-mentioned valve body middle part obliquely and is connected with valve body, and the mouth of pipe edge of above-mentioned arm is threaded.
Above-mentioned swivel joint outer surface has the striped that is arranged in parallel along the valve axis direction of some protrusions, and above-mentioned spiral cover outer surface has the striped that is arranged in parallel along the valve axis direction of some protrusions.
Owing to adopted above-mentioned technical solution, solved the problem that in intervene operation, prevents oozing of blood fully, and can connect the cock of multi-path by the joint of adapter, can connect various instruments such as pressure monitor, contrast agent, heparin-saline etc. all can enter by multi-path.
