Versatile exhausting box for blood transfusion

Abstract

A universal transfusion exhaust case is characterized by including an exhaust film (1), a liquid separating case (2) and an exhaust cover (3), wherein a concave liquid separating slot (4) is arranged in parallel on the liquid separating case (2), the liquid separating case (2) and the exhaust cover (3) are involutive to clamp the exhaust film (1), and a transfusion flux adjuster is arranged at the backward position of the universal transfusion exhaust case, meanwhile the liquid separating slot (4) is arranged in parallel. The inner surface of the liquid separating case (2) is corresponding to the inner surface of the exhaust cover (3), and a whole piece of exhaust film (1) are disposed therebetween, while the inner surface of the liquid separating case (2) has the aerating and staunch nature. The invention realizes the no dead angle exhaust and prevents the exhaust film pumping back the air, and the exhaust function of a plurality of angles of each posture, ensures no exhaust dead angle, and finally overcomes the problems of dead angle pneumatosis.

Description

technical field [0001] The invention relates to a disposable infusion set in medical equipment, in particular to a universal infusion exhaust box, which prevents the occurrence of the dangerous situation that the exhaust film is sucked back into the infusion pipeline during gravity infusion, and at the same time realizes It realizes the exhaust function at various angles in various positions, ensures that there is no exhaust dead angle, and finally overcomes the problem of dead angle gas accumulation. technical background [0002] The purpose of the present invention is to provide a universal transfusion exhaust box. The present invention prevents the occurrence of the dangerous situation that the venting film is sucked back into the infusion pipeline during gravity infusion, and at the same time realizes the infusion in various body positions. The exhaust function of various angles ensures that there is no exhaust dead angle, and finally overcomes the problem of dead angle ...

AI Technical Summary

Problems solved by technology

[0003] The existing technology includes the problems in the design of "direct membrane temperature sensitive blood return self-venting infusion filter" invented by myself with the patent application number of 200510276096. For example: the filter membrane is designed in the middle and protrudes outward, so that the edge has exhaust There is a dead angle. Under certain circumstances, for example, under the infusion conditions that are routinely used today, after the infusion of the upstream liquid medicine is stopped or the exhaust part is raised so that the upstream liquid medicine no longer flows downstream, air reaction may occur. The dangerous situation of continuing to infuse into the body into the inhaled infusion line; other existing products, such as: the precision filter of American Ball, the precision filter infusion set of Tianjin HANACO, the precision filter exhaust produced by Weihai Polymer Factory Infusion sets, etc., all use a single exhaust hole on the plane and a single exhaust film sealed inside. There are obviously exhaust dead angles during use, and there are directional choices. The common ones proved by experiments are more serious. The problem also lies in the fact that the flow regulator is located upstream of the venting membrane, and in use, there will be the aforementioned dangerous problem of back pumping gas into the infusion line
