Description
Technical Field
The utility model relates to the field of medical equipment, especially a dropping funnel for blood transfusion set.
Background
At present, two combination forms of a dropping funnel and a filter screen of a blood transfusion dropping funnel used clinically are generally adopted, firstly, the dropping funnel is directly bonded at the position of a liquid outlet at the lower end of the dropping funnel in a heat sealing way, and the filter screen is made of nylon and has poor fusion with PVC of the dropping funnel, so that the situation of liquid leakage at the joint of the two heat sealing surfaces often occurs, blood leaks to pollute a medical environment, the chance of blood contact of medical personnel is increased, and the occupational exposure risk of the medical personnel is increased; secondly, the full-support filter screen is placed inside the dropping funnel, the full-support filter screen is large in size and high in cost, and the risk that blood clots are blocked at the bottom of the filter screen after long-time blood transfusion can occur, so that the blood transfusion speed is influenced, and the risk of patients is increased.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a dropping funnel for a blood transfusion device, which has simple structure, high sealing performance and smooth blood transfusion, aiming at the defects of the prior art.
The technical problem to be solved by the utility model is realized through the following technical scheme.
The utility model provides a dropping funnel for blood transfusion ware, including the dropping funnel body, the fixed dropping funnel block that is equipped with in upper portion of dropping funnel body, its characteristics are:
a filter is arranged on a liquid outlet at the bottom end of the dropping funnel body and comprises a cylindrical support, and the outer wall of the cylindrical support is tightly connected with the inner wall of the dropping funnel body;
the bottom of the filter screen is fixedly connected to the inner wall of the cylindrical support, and the top of the filter screen is arranged in a sealing manner;
the lower part of the interior of the dropping funnel body is provided with a limiting mechanism used for limiting the cylindrical support to move upwards.
The dropping funnel for the blood transfusion device has the following further optimized technical scheme: the filter screen is a conical filter screen.
The dropping funnel for the blood transfusion device has the following further optimized technical scheme: the limiting mechanism comprises a circle of cylindrical bosses arranged along the inner wall of the dropping funnel body.
The dropping funnel for the blood transfusion device has the following further optimized technical scheme: the distance between the limiting mechanism and the bottom end of the dropping funnel body is 7mm-10 mm.
The dropping funnel for the blood transfusion device has the following further optimized technical scheme: the height of the cylindrical support is the same as the distance between the limiting mechanism and the bottom end of the dropping funnel body.
The dropping funnel for the blood transfusion device has the following further optimized technical scheme: the height of the filter is larger than half of the height of the dropping funnel body.
The dropping funnel for the blood transfusion device has the following further optimized technical scheme: the inner wall of the filter screen is provided with a support framework for preventing the filter screen from sinking.
Compared with the prior art, the utility model discloses simple structure, it is convenient to make, novel filter screen design material saving, and the method in use of inversion installation is difficult for blockking up to the speed of blood transfusion treatment has been guaranteed. The filter screen is inlaid in the dropping funnel, so that the leakage risk is avoided, the occupational exposure risk of medical personnel is reduced, the contradiction between doctors and patients is relieved, and the satisfaction degree of patients is improved.
