Abstract
The invention relates to a disposable medical safe infusion apparatus, which is capable of automatically sounding an alarm when the liquid medicine in an infusion bottle is nearly running out, and automatically closing an infusion catheter when the liquid medicine drops to the bottom of a Murphy pipette, so as to stop the liquid medicine to further flow downwards. The medical safe infusion apparatus is characterized in that: an alarm is arranged on a puncture outfit in order to give an alarm when the liquid medicine is running out; a needle valve able to suspend in the liquid medicine is arranged inside the Murphy pipette, so that the infusion catheter can be automatically closed when the liquid flows to the bottom of the pipette, so as to prevent the liquid from dropping and protect the patients from the dangers of blood backflow and air embolism.
Description
Technical field
The present invention relates to a kind of transfusion medical apparatus and instruments, especially when transfusion finishes, can report to the police automatically and when medicinal liquid is reduced to luxuriant luxuriant and rich with fragrance dropper bottom, close tube for transfusion automatically, stop further dirty Dispoable medical safe transfusion system of medicinal liquid.
Background technology
At present, known transfusion device partly is made up of perforator, exhaustor, tube for transfusion, luxuriant luxuriant and rich with fragrance dropper, actuator etc.In use, when transfusion finishes and in time do not change medicinal liquid or pull out pin, might make the patient that the danger of backflow of blood or air embolism takes place.
Summary of the invention
In order to overcome the danger that existing transfusion device in use may cause backflow of blood or air embolism to the patient, the invention provides a kind of safe transfusion system.This transfusion device can be reported to the police when transfusion finishes automatically, and the prompting nursing staff in time changes dressings or pulls out pin; The nursing staff not to and medicinal liquid when continuing to drop to luxuriant luxuriant and rich with fragrance dropper bottom is closed tube for transfusion automatically, thereby is avoided dangerous generation.
The present invention solves the scheme that its technical problem adopts: the alarm of ining succession on perforator, its ogival is equipped with two electrodes, electrode is connected to the music alarm modular circuit, alarm module and battery, piezoelectric ceramic piece etc. are installed in the plastic casing that connects together with perforator, and on and off switch and display lamp are housed on the plastic casing limit.A needle-valve that can be suspended in the medicinal liquid is housed in luxuriant luxuriant and rich with fragrance dropper, and it is made of guide pillar part, cone valve part, counterweight column part.Guide pillar partly is arranged in tube for transfusion down.
In use, perforator is thrust in the infusion bottle, with the infusion bottle reversal of the natural order of things, turn on the power switch then, this moment, power supply indicator was bright.Because of being imbedded in two electrodes in the perforator by the medicinal liquid conducting, music alarm circuit is in cut-off state; When the bottle herb liquid drops to electrode when following, the electrode of conducting is disconnected, and warning circuit transfers conducting to by cut-off state, and piezoelectric ceramic piece sends chimes of doom.When medicinal liquid continued to drop to luxuriant luxuriant and rich with fragrance dropper bottom, the needle-valve that is suspended in the medicinal liquid was closed tube for transfusion with medicinal liquid decline, and it is dirty that medicinal liquid is stopped, thereby avoid dangerous generation.
The invention has the beneficial effects as follows: when transfusion finishes, can report to the police automatically; And drop to luxuriant phenanthrene at medicinal liquid and drip when bottom visitor, close tube for transfusion automatically, stop medicinal liquid further dirty, avoid taking place backflow of blood or air embolism, eliminate patient and entourage's mental pressure, alleviate their fatigue.
The specific embodiment
Perforator and plastic casing and two electrodes constitute one by mould through injection moulding; Battery, piezoelectric ceramic piece, warning circuit, on and off switch, display lamp etc. are connected, put in the box.That needle-valve adopts is nontoxic, density is formed by injection molding less than the high molecule plastic of water; Its counterweight column part external diameter is less than dropper union joint external diameter, and greater than the union joint internal diameter; Guide pillar part external diameter is less than the union joint internal diameter; The cone valve part is between counterweight circle bolt and guide pillar; The needle-valve total length is greater than luxuriant luxuriant and rich with fragrance dropper length.Guide pillar is partly packed into union joint, fill in the dropper from luxuriant luxuriant and rich with fragrance dropper end opening.
The luxuriant luxuriant and rich with fragrance dropper of exhaustor, perforator, the tube for transfusion of band alarm, built-in needle-valve, actuator etc. are assembled in order.
Claims (3)
1. a safe transfusion system partly is made up of perforator, exhaustor, tube for transfusion, luxuriant luxuriant and rich with fragrance dropper, actuator etc., it is characterized in that: an alarm is housed on the perforator, and in luxuriant luxuriant and rich with fragrance dropper a needle-valve that is suspended in only in the medicinal liquid is housed.
2. safe transfusion system according to claim 1 is characterized in that: perforator and body case of annunciator are an integral body.
3. safe transfusion system according to claim 1 is characterized in that: needle-valve is made of guide pillar part, cone valve part, counterweight column part.
