Abstract
An anti-counterflow positive-pressure needleless four-way joint is mainly composed of a single-channel positive-pressure joint and is characterized in that two sides of the single-channel positive-pressure joint are provided with anti-counterflow needleless joints. The anti-counterflow positive-pressure needleless four-way joint has the following functions: preventing resource wastage caused by repeated connection of a three-way heparin cap, reducing expenditure of the patient, simplifying flows in treatment and nursing, improving rescue speed, preventing injury which may be caused to the nurse, eliminating the necessary for puncturing the heparin cap by a puncture needle, preventing entering of small particles into a transfusion system, and preventing damage to the patient.
Description
Technical field
This utility model relates to medical medical instruments field, is specifically related to a kind of counterflow-preventing positive pressure needle-free four-way connection that uses clinically.
Background technology
Dark Vein Tube has been opened a venous access fast and effectively for critical in ICU, NICU, CCU and EICU.various dark venous ductes are usually used in hemodynamic monitoring, the strong stimulation drug administration, fluid infusion and parenteral nutrition support, we find because conditions of patients is critical in clinical position, often need open many venous accesses (general 3-6 bar) simultaneously, the nurse follows the doctor's advice often in single chamber, two-chamber, and even administration when satisfying many venous accesses that three caval vein conduits connect threeway and calparine cap outward repeatedly, not only waste time and energy, reduce rescue speed, incur loss through delay rescue opportunity, and increase workload and consumptive material, bring discomfort to the patient after simultaneously long joint is fixing, make troubles for the conduit maintenance work, and it has pin infusion model sharp transfusion needle point in piercing process can cut the silica gel joint to take chip out of, pollute medicinal liquid, the patient is caused potential safety hazard, the danger that medical personnel easily meet accident and stab.
The utility model content
The purpose of this utility model be design in order to address the above problem can reduce nursing work load and consumptive material, increase work efficiency, avoid the counterflow-preventing positive pressure needle-free four-way connection of needle injuries.
Counterflow-preventing positive pressure needle-free four-way connection mainly is made of single channel positive pressure needle-free joint, and wherein the both sides of single channel positive pressure needle-free joint are provided with the counterflow-preventing needleless joint.
The wasting of resources that counterflow-preventing positive pressure needle-free four-way connection of the present utility model had avoided in the past repeatedly the connecting tee calparine cap to cause, saved patient's expense, simplified the flow process for the treatment of nursing, improved rescue speed, avoided the injury to the nurse that may cause, need not to use the lancet puncture calparine cap, avoid molecule to enter transfusion system, cause the infringement to the patient.
Description of drawings
Fig. 1 is structural representation of the present utility model
The specific embodiment
As shown in Figure 1, counterflow-preventing positive pressure needle-free four-way connection, mainly consisted of by single channel positive pressure needle-free joint 1, both sides at single channel positive pressure needle-free joint are respectively arranged with counterflow-preventing needleless joint 2, counterflow-preventing needleless joint 2 is integrated with single channel positive pressure needle-free joint 1 and is connected as one, and integral body is the steel fork type.
during clinical use, after dark Vein Tube establishes venous access, joint 3 is connected with medical apparatus and instruments such as inlying catheters, when following the doctor's advice open two or more venous accesses, sterilize respectively single channel positive pressure needle-free joint 1 and counterflow-preventing needleless joint 2 (transverse section 〉=10 time of disinfecting cotton swab, side 〉=10 time), common needle-free tube for transfusion is connected with counterflow-preventing needleless joint 2, directly carry out intravenously administrable, not before the transfusion, the silicon rubber cup of counterflow-preventing needleless joint 2 inside and joint exit are in sealing state, when tube for transfusion with after counterflow-preventing needleless joint 2 is connected, extruding due to the tube for transfusion head end, make inner silicon rubber cup generation elastic deformation, then the sealing state with the joint exit disappears, when transfusion is completed when withdrawing from tube for transfusion, do not have under External Force Acting, silicon rubber cup restores to the original state, again with joint exit formation sealing state, prevented overflowing of blood and medicinal liquid, during the urgent intravenous administration of clinical needs, can directly carry out needleless by single channel positive pressure needle-free joint 1 and connect administration, need not to close the tube for transfusion liquid control valve that is connected on both sides counterflow-preventing needleless joint 2, the anti-backflow device of its counterflow-preventing needleless joint 2 inside, the medicine that causes when effectively stoping by single channel positive pressure needle-free joint 1 direct intravenous administration backflows, when infusion-completed is pulled out transfusion catheter or syringe, make the malleation of a continuation promotion of its inner meeting generation due to the reason of single channel positive pressure needle-free joint 1 inner structural features, thereby prevent liquid or blood backflow.This utility model also is adapted to clinically variously need multichannel to infuse simultaneously or need to carry out the section office of no-needle transfusion.
Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that produces does not exceed the scope of technical solutions of the utility model, all belong to protection of the present utility model.
