Abstract
Disclosed is a pipe connecting device connected with a medical solution filter. Inner threads are arranged in an inner cavity of the right side of a first filter shell. A cone-shape protrusion is arranged in the middle of the inner cavity of the right side of the first filter shell. A big-left-end and small-left-end cone is arranged on the outer portion of the cone-shape protrusion. A through hole is arranged in the middle portion of the cone and communicated with a transfusion pipe. The outer periphery of the left end of a connecting pipe head is provided with outer threads in match with the inner threads of the inner cavity of the right side of the first filter shell. The left end of the connecting pipe head is provided with an opened inner cavity which is in fit with the cone on the outer portion of the cone-shape protrusion. The outer diameter of the inner cavity is a conical surface which is large at the left end and small at the right end. Process of screwing in a connecting pipe head through threads is process of combining the connecting pipe head with the first filter shell through the conical surface. The pipe connecting device connected with the medical solution filter is reliable in connection, not prone to enabling the transfusion pipe to be separated under the weighted condition, and capable of ensuring smooth transfusion.
Description
Affiliated technical field
This utility model relates to medical instruments field, especially is applicable to the assembling pipe joint that connects with liquid medicine filter.
Background technology
In giving patient's infusion process, medicinal liquid there is defecator.Be connected for the pipeline with the liquid medicine filter connection, traditional device is in the end of liquid medicine filter pipe joint to be set, and directly connects with liquid-transport pipe-line.Its weak point is: this syndeton by frictional force between pile crown and the liquid-transport pipe-line, it is unreliable to connect, might make pile crown and liquid-transport pipe-line disengaging in the stressed situation slightly meeting, and can not infuse smoothly.
The utility model content
The purpose of this utility model is to provide the assembling pipe joint that connects with liquid medicine filter in order to overcome above-mentioned weak point, connects reliably, even run into liquid-transport pipe-line is broken away from, and guarantees smoothly transfusion.
The technical scheme that its technical problem that solves this utility model adopts is: the assembling pipe joint that connects with liquid medicine filter, in the left side of liquid medicine filter pipe joint is arranged, and the rubber tube for transfusion is connected with pipe joint.Inner chamber at liquid medicine filter arranges filter element.Filter housing second and filter housing first are by the bonding shell integral body that becomes.The right side inner chamber of filter housing second has female thread, has pyramidal projections at the middle part of filter housing second right side inner chamber, and the outside of pyramidal projections is the little cone of the large right-hand member of left end, and the middle part of pyramidal projections is through hole, and liquid-transport pipe-line links.The left end periphery that connects tube head has external screw thread, and the female thread of filter housing second right side inner chamber matches.The left end that connects tube head has the inner chamber of opening, its inner chamber external diameter is the little conical surface of the large right-hand member of left end, match with the cone of pyramidal projections outside, when connecting the process of tube head by the screw thread precession, connect exactly the process that tube head combines by the conical surface and filter housing second.At connection tube head external diameter fin is arranged, so that precession and back-out.Connect the tube head inner chamber and have through hole, and liquid-transport pipe-line links.
Effective effect of the present utility model is, uses the assembling pipe joint that liquid medicine filter of the present utility model connects, and connects reliably, even run into liquid-transport pipe-line broken away from, and guarantees smoothly transfusion.
Description of drawings
Figure is the structural representation of the assembling pipe joint that connects with liquid medicine filter of the present utility model.1-rubber tube for transfusion among the figure, 2-filter housing first, the 3-filter element, 4-filter housing second, the 5-pyramidal projections, 6-connects tube head, 7-fin.
The specific embodiment
The right side inner chamber of filter housing second (4) has female thread, the pattern of female thread is trapezoidal thread, middle part at the right side inner chamber of filter housing second (4) has pyramidal projections (5), the outside of pyramidal projections is the little cone of the large right-hand member of left end, cone 6: 100, the middle part of pyramidal projections is through hole, and liquid-transport pipe-line links.The left end periphery that connects tube head (6) has external screw thread, and the female thread of filter housing second right side inner chamber matches.The left end that connects tube head (6) has the inner chamber of opening, its inner chamber external diameter is the little conical surface of the large right-hand member of left end, and the outside cone of pyramidal projections (5) matches, when connecting the process of tube head (6) by the screw thread precession, connect exactly the process that tube head (6) combines by the conical surface and filter housing second (4).At connection tube head (6) external diameter fin (7) is arranged, so that precession and back-out.Connect tube head (6) inner chamber and have through hole, and liquid-transport pipe-line links.
Claims (1)
1. the assembling pipe joint that connects with liquid medicine filter, it is characterized in that: the right side inner chamber of filter housing second has female thread, middle part at the right side inner chamber has pyramidal projections, the outside of pyramidal projections is the little cone of the large right-hand member of left end, the middle part of pyramidal projections is through hole, and liquid-transport pipe-line links; The left end periphery that connects tube head has external screw thread, match with the female thread of filter housing second right side inner chamber, the left end that connects tube head has the inner chamber of opening, its inner chamber external diameter is the little conical surface of the large right-hand member of left end, match with the cone of pyramidal projections outside, at connection tube head external diameter fin is arranged, connect the tube head inner chamber and have through hole, and liquid-transport pipe-line links.
