Description
Technical field:
The invention relates to the technical field of medical infusion equipment, in particular to a medical infusion forward flow joint device capable of effectively preventing blood from flowing back and blocking an infusion tube/hole.
The background technology is as follows:
at present, when a hospital infuses a patient with a medical fluid, an infusion connection device such as a connector is often used to facilitate the transfer of fluid from one medical device to another, such as a connection between an infusion set and an indwelling needle. The positive pressure infusion connecting device is a needleless infusion device, so that falling scraps generated by needle point puncture are prevented from polluting liquid medicine, meanwhile, medical staff are prevented from being accidentally injured by the needle point, a positive pressure effect can be generated after connection is disconnected, and the occurrence of tube blockage caused by blood return is avoided.
Patent document CN 104815363a discloses a positive pressure connecting piece, which comprises a needleless connector and a rubber plug, wherein the rubber plug consists of a solid part and a hollow part, the rubber plug is arranged in an inner cavity of the needleless connector, when the positive pressure connecting piece is used, the positive pressure connecting piece is connected with external infusion equipment, the external equipment presses the upper end face of the solid part, a groove is deformed after the solid part is pressed, the solid part presses the hollow part to deform, the external equipment is smoothly connected with the inner cavity, and when the external equipment leaves, the hollow part rebounds. In order to improve the rebound ability of the hollow part, the above document describes that ribs are arranged on the outer side of the hollow part, are discontinuous or form an included angle of 70 degrees, 85 degrees and 30 degrees with the horizontal plane or are X-shaped combined ribs, and are used for solving the problems that the rebound ability of the hollow part is weak or the hollow part is easy to block when rebounding.
In practice, the direction of the infusion pressure of the external device determines that the optimal deformation direction of the hollow part is coincident with the central axis of the hollow part, in the above technical scheme, the best resilience force can be obtained only when the rib is coincident with the central axis of the hollow part, namely, the rib is arranged on the outer wall of the hollow part in a flat way, and other schemes such as the intermittent rib or the included angles of 70 degrees, 85 degrees and 30 degrees between the rib and the horizontal plane are dispersed by the rib in the actual stress process, so that the smooth rebound effect of the hollow part along the central axis is reduced, and the clamping and the blocking are easy to occur along the rib direction; when the rib is a straight rib or an X-shaped combined rib, although better resilience force can be obtained, the hollow part can deform to cause barriers, so that when external infusion equipment is accessed, the hollow part cannot deform enough under the action of external infusion pressure, and the positive pressure effect is affected.
In addition, the input end of the connector in the prior art is a soft elastic piece, the elastic piece is provided with an opening, and liquid is input through the opening. When the infusion apparatus is connected with the extrusion elastic piece in use, the extrusion is insufficient due to the elasticity of the elastic piece, and the elastic piece cannot be reduced to the maximum extent; and the opening on the elastic piece is extruded to be smaller, which is easy to cause the phenomenon of unsmooth infusion.
