Abstract
The utility model discloses a novel self-exhausting remaining needle. The novel self-exhausting remaining needle comprises a needle head assembly and a Y-shaped needle base which are connected through a guide tube. A heparin cap is arranged at one end of the Y-shaped needle base. An anti-microbial cap is arranged at the other end of the Y-shaped needle base. The top of the anti-microbial cap is provided with an exhaust hole. A hydrophobic breathable film is arranged at the exhaust hole. According to the novel self-exhausting remaining needle, air in the Y-shaped needle base in clinical use can be exhausted through the hydrophobic breathable film arranged at the exhaust hole in the top of the anti-microbial cap, and therefore the mental health and physical health of a patient are guaranteed.
Description
Technical field
This utility model relates to a kind of armarium, particularly a kind of Novel self-exhaust formula remaining needle.
Background technology
Y type remaining needle is generally applied in clinically, is a kind ofly can be retained in for a long time the product in human body, is mainly to use to the patient that need to repeatedly infuse.Common using method is clinically that intravenous needle is inserted in the calparine cap of remaining needle, then carries out aerofluxus and puncture.But the gas having in clinical use in Y type remaining needle can not, by the situation of emptying, bring psychology and physiological injury to patient.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of Novel self-exhaust formula remaining needle of avoiding bringing menticide and physiology injury to patient.
The technical problems to be solved in the utility model is achieved through the following technical solutions.This utility model is a kind of Novel self-exhaust formula remaining needle, comprise the needle assembly and the Y type needle stand that connect by conduit, one end at Y type needle stand is provided with calparine cap, the other end at Y type needle stand is provided with Bacteria-prevention cap, be characterized in: the top at Bacteria-prevention cap is provided with steam vent, and at steam vent, place is provided with hydrophobic permeable membrane.
In a kind of Novel self-exhaust formula of this utility model remaining needle technical scheme, further preferred technical scheme feature is:
1, in Bacteria-prevention cap, be provided with female thread, the one end that connects Bacteria-prevention cap at Y type needle stand is provided with the union joint coordinating with Bacteria-prevention cap, is provided with the external screw thread with screw-internal thread fit in the outer end of union joint.
2, in union joint, be provided with sealing member, be provided with the exhaust passage that connects Y type needle stand chamber and steam vent on sealing member, described sealing member is provided with the nosing of protruding union joint, and the diameter of section of nosing is larger than the internal diameter of tube body of union joint.
Compared with prior art, this utility model utilization is arranged on the hydrophobic permeable membrane at steam vent place, Bacteria-prevention cap top, can in clinical use, make the gas in Y type needle stand discharge, and ensures outpatients mental state and physiological health.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of Bacteria-prevention cap.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands this utility model further, and do not form the restriction of its power.
Embodiment 1, with reference to Fig. 1,2, a kind of Novel self-exhaust formula remaining needle, comprise the needle assembly 1 and the Y type needle stand 2 that connect by conduit, one end at Y type needle stand 2 is provided with calparine cap 3, the other end at Y type needle stand is provided with Bacteria-prevention cap 4, is provided with steam vent 6 at the top of Bacteria-prevention cap 4, and at steam vent, 6 places are provided with hydrophobic permeable membrane 5.Calparine cap 3 is communicated with tube for transfusion, at this moment, can utilize the hydrophobic permeable membrane 5 on Bacteria-prevention cap 4 to allow gas by not allowing liquid to pass through, make remaining needle can pass through Bacteria-prevention cap aerofluxus.
Embodiment 2, in the Novel self-exhaust formula remaining needle described in embodiment 1: be provided with female thread in Bacteria-prevention cap 4, the one end that connects Bacteria-prevention cap 4 at Y type needle stand 2 is provided with the union joint coordinating with Bacteria-prevention cap, is provided with the external screw thread with screw-internal thread fit in the outer end of union joint.
Embodiment 3, in Novel self-exhaust formula remaining needle described in embodiment 1 or 2: be provided with sealing member in union joint, on sealing member, be provided with the exhaust passage that connects Y type needle stand chamber and steam vent, described sealing member is provided with the nosing of protruding union joint, and the diameter of section of nosing is larger than the internal diameter of tube body of union joint.
