Abstract

The utility model provides an accessory for safe infusion, and aims to realize safe and convenient intravenous infusion. The accessory adopts the structure that an automatic alarm circuit is mounted in a tailor-made small and exquisite container compactly; the automatic alarm circuit comprises a battery, a switch, an extension spring, a music integrated chip, a magnetic sensor and an acousto-optic display; and the extension spring is provided with a hook and a small magnet block. The extension spring is stretched when an infusion bag or an infusion bottle is hung on the accessory, and the stop baffle plate can limit the extension of the extension spring; and when the liquid medicine in the infusion bag or the infusion bottle is to be used up, the extension spring can resile, so that the magnetic sensor device is started, and an alarm apparatus is triggered to give an acousto-optic alarm. By adopting the utility model, medical accidents such as blood reflux, blood coagulation and the like which can be caused by carelessness of people due to visual fatigue can be avoided, so that the nursing staff and the patient feel relax during infusion monitoring process.

Description

The safe infusion accessory

Technical field

This utility model relates to the accessory of medical vein infusion treatment equipment, refers in particular to a kind of safer reliable safe infusion accessory of infusion treatment process that makes.

Background technology

Current China big infirmary in various places all adopts the venous transfusion treatment means in a large number, but infusion process relies on artificial the supervision for a long time, promptly needs nurse or patient oneself or families of patients when to pay close attention to, watch out at any time transfusion near stopping.In case malpracticees such as blood backflow, blood coagulation just might take place in carelessness.And uninteresting monitoring process is easy to cause people's visual fatigue.Therefore have hundreds of patented technologies to come out in recent years, it is as follows that this selects several commentaries.

(1) weighing principle type: as No. 200510045210.3, No. 200520106539.1, No. 200420051970.6, they are similar, the detection of weighing.A comment: all non-constant of all employing mechanical contact person reliabilities! Owing to unreliable its practical value of losing.

(2) liquid conduction principle type: as No. 9712022.5,02224171.x number, electrode need be set in medicinal liquid, this is low-cost achievable technology anything but, though principle is clear, effect is reliable, relates to and disturbs drug effect to be difficult to get permission to emerge application.

(3) Photoelectric Detection mode:, No. 200420011766.1, No. 200520033484.6, adopt correlation or reflective or laser type with the beam detection liquid level as No. 02132743.2.Comment: the practical difficulty of principle novelty because the medicinal liquid kind varies, so difficult heavy burden of easy detection appointed, and senior, that the complex detection cost is high, condition is sternly popularized is difficult.

(4) capacitive position sensor: detect liquid level with advanced liquid level sensor and be better than photovoltaic certainly, and it is rotten can not produce photic medicinal liquid, problem is to have brought higher cost.

(5) float blocking valve: as No. 93206484.1, adopting increases the device that automatically closes up between plastic connector pin and Mao Feishi dropper, establish floating plug in the occluder, and floating plug can self-blocking be lived the passage of medicinal liquid.Comment: it is too high to make required precision, so limited by practical.

Summary of the invention

The purpose of this utility model provides a kind of simple and practical reliable again method, does not change existing fluid delivery apparatus, reminds especially when but effectively providing institute's loading liquid to use up for user.

Realize that the technical scheme that above-mentioned purpose adopted is such: in special small and exquisite container, be equipped with by battery, switch, music ic and sound and light display, band hook and with extension spring and the automatic alarm circuit that Magnetic Sensor is formed, the small sircle hole and the circular hole wall of offering by the box body bottom of little magnetic piece and constitute the spring lock plate.

Little magnetic piece invests spring end, spring bottom coupling hook, can hang any transfusion bag or infusion bottle under the hook, as long as medicinal liquid is more than default definite value such as 50ml (illustrate: this default definite value can be regulated its numerical value on demand), spring just be elongated (illustrate: long time also with regard to stop bit in spring lock plate place), this moment, the spring end magnetic piece was away from Magnetic Sensor, sound and light display is static, and in case the bag in or the bottle herb liquid be less than setting value, spring just bounces back, cause little magnetic piece near Magnetic Sensor, pick off becomes " conducting " by " shutoff ", trigger music ic and sound and light display immediately and play the music sound and be equipped with flash signal, in order to remind: medicinal liquid is to the greatest extent defeated soon, please in time handles. handle and be divided into or add medicinal liquid---continue to infuse; Or extract syringe needle---finish transfusion.

This accessory directly contacts medicinal liquid without any parts, and the magnetic sensing device is the fully-sealed non-contact electrical switch, and is safe and reliable.

The beneficial effects of the utility model are: adopt described safe infusion accessory, need not change existing fluid delivery apparatus, just can be effectively, the vast user of big infirmary sends special prompting when most for providing transfusion operation process medicinal liquid to fail, prevent people when visual fatigue because of malpracticees such as the contingent blood backflow of negligence, blood coagulations, thereby nursing staff, the intense strain of patient oneself in paying close attention to infusion process are loosened greatly, helped carrying out smoothly of venous transfusion treatment disease.

Description of drawings

Fig. 1 is this utility model " safe infusion accessory " example structure sketch map.

State when Fig. 2 to be this utility model " safe infusion accessory " embodiment hang with under hook transfusion bag or infusion bottle rear spring are elongated---lock plate was brought into play effect-spring and was limited can infinitely not elongate and exceeds beyond the elastic limit of spring this moment.

Fig. 3 is an electrical schematic diagram, to allow its operation principle of those skilled in the art's understood in detail.

Each several part title among the figure: 1-lanyard; The 2-shell; The 3-battery; The 4-switch; The 5-sound and light display; The 6-extension spring; The 7-IC chip; The 8-Magnetic Sensor; The little magnetic piece of 9-; 10-lock plate: 11-hook, 12-transfusion bag (bottle).

The specific embodiment

In the embodiment shown in fig. 1, except that lanyard 1, shell 2, extension spring 6, little magnetic piece 9, lock plate 10, hook 11, battery 3, switch 4, sound and light display 5, IC chip 7, Magnetic Sensor 8 are according to the electric connection of Fig. 3.During use lanyard 1 is hung over the drip stand top, open switch 4 and should be able to hear that musical sound sounds, but after hook 11 had hung up medicinal fluid bag (bottle) 12, extension spring 6 is elongated sound at once must be ended, the transfusion beginning.The spring of infusing when medicinal liquid will be use up is replied former length, and at this moment little magnetic piece 9 is near Magnetic Sensors 8, and the magnetic sensing device starts, and triggers Music Clip 7 sound and light display 5 is reported to the police in the acousto-optic mode, reminds the nurse to add medicinal liquid or pull out the pin stopping transportation.
