Disposable passive intravenous infusion apparatus with multi-bag continuous injection pause function

Abstract

The invention discloses a disposable passive intravenous infusion apparatus with a multi-bag continuous injection pause function. The disposable passive intravenous infusion apparatus comprises a plurality of infusion bags, bottle stopper puncture devices, air filter tubes, a four-way connector, infusion pause devices, a Murphy drip kettle, a liquid filter, an infusion tube, a wheel clamping flow regulator, a scalp needle and a multi-bag liquid suspension bracket. A top hole, upper / lower side holes and a bottom hole are formed in the four-way connector which is of a cuboid structure, the upper / lower side holes are provided with check valves, and the infusion bags which are suspended at different altitudes are connected with the different holes of the four-way connector by the respective bottle stopper puncture devices. The disposable passive intravenous infusion apparatus has the advantages that intravenous infusion liquid in the multiple bags can be automatically, passively and continuously injected into a patient by the aid of static pressures of different liquid levels; a passive multi-bag continuous injection solution follows the structure and a service method of a mainstream disposable intravenous infusion apparatus to the greatest extent, and the disposable passive intravenous infusion apparatus is safe and reliable, and is low in cost and convenient to use and popularize; requirements of the patient on infusion pause and physical activities for settling physiological needs can be met by the PVC (polyvinyl chloride) infusion pause devices which are of butt nut and screw structures.

Description

technical field [0001] The invention relates to the technical category of a disposable venous infusion set, in particular to a disposable passive venous infusion set with multiple bags that can be paused continuously. Background technique [0002] Intravenous infusion is one of the main techniques for drug administration in clinical treatment, and it is the preferred technique in emergency and trauma situations; medical statistics indicate that 90% to 95% of hospitalized patients require intravenous infusion therapy. The intravenous infusion set has the functions of puncturing, conveying, measuring, regulating, filtering, connecting, and air intake, and it should also provide the function of refilling when necessary. Ordinary intravenous infusion sets are usually composed of bottle stopper piercer protective cover, bottle stopper piercer, exhaust pipe, Murphy's drip pot, liquid medicine filter, infusion tube, wheel clip flow regulator, scalp needle and connecting accessories...

AI Technical Summary

Problems solved by technology

The detection technology improves the infusion experience of medical staff, escorts and patients, but also brings a series of problems: infrared / ultrasonic / laser / capacitance / strain resistance detection technology is active and will make disposable intravenous infusion sets The advantages of simplicity and ease of operation are gone--complex power supply / signal lines and new electronic components increase complexity and reduce reliability, and the introduction of electric shock hazards will lead to a decrease in safety indicators; active detection technology requires third-party Professional technical support has increased the management difficulty of medical institutions and patient expenses. Even the simplest and first liquid level detection based on the principle of spring weighing medicine bag weight (such as the intelligent infusion monitoring of Hangzhou Tige Technology Co., Ltd. System, Hangzhou Farrell Technology Co., Ltd. wireless infusion monitoring system) is also difficult to successfully penetrate into the infusion room of medical institutions. After all, the choice of technology must comprehensively weigh the benefits and costs. The benefits are limited and the cost is high (high failure rate and difficult maintenance ) technology prospects are worrying

Therefore, it is necessary to conduct in-depth research based on the existing disposable venous infusion set and within the framework of improving the constraints of the disposable venous infusion set: under the passive premise, design a disposable venous infusion set with multiple bags continuously, and finally The end of the bag of intravenous infusion is still completed by manual observation; although the experience of intravenous infusion is not as good as that of the automatic cut-off intravenous infusion set, it is within the scope of human competence to observe the process of a bag of intravenous infusion

It must be pointed out that the time for continuous infusion of multiple bags of intravenous infusion is > 2 hours; if the patient needs to suspend infusion during single-bag intravenous infusion, and move around to meet physiological needs and feel inconvenient, the setting of intravenous infusion sets for multiple bags of continuous infusion allows patients to suspend intravenous infusion, Devices for moving the body to meet physiological needs are essential; otherwise, the practical value of multi-bag disposable intravenous infusion sets will be greatly reduced
