Abstract

Disclosed is a disposable auto- alarm infusion set, including a Murphy pot and a pot lid, wherein, a drip tube and an air- inlet tube are arranged on the pot lid; the lower end of the Murphy pot is provided with an outlet tube. The improvements are that a bobber is arranged in the cavity of the Murphy pot; a sliding sleeve is sleeved on the drip tube; a connecting rib is arranged between the bobber and the sliding sleeve; a plunger- typed movable contact is arranged on the pod lid; the lower end of a movable plunger of the contact props up on the sliding sleeve; a micro integrated circuit alarm is inserted in the end hole of the plunger- typed movable contact; an anode contact and a cathode contact corresponding to the alarm plug are arranged in the end hole; the movable plunger whose upper part is provided with a conductive contact ring is positioned in a dead hole at the lower part of the plunger- typed movable contact; two electric contacts which are connected with the anode contact and the cathode contact in the end hole through a conductor are arranged on the middle part of dead hole of the plunger- typed movable contact. The utility model can emit sound signals or light signals when the infusion is finished, so that the medical workers can be alarmed for treatment in time.

Description

Automatic alarming, disposable uses transfusion device

Technical field

The medical apparatus that a kind of infusion treatment is used.

Background technology

The disposable infusion set that present hospital uses is the gravity type transfusion device, has advantage simple and practical, cheap, evident in efficacy, when being the transfusion end, its greatest drawback can not send relevant signal automatically, need medical care or entourage constantly to observe for a long time, in case transfusion finishes to cause accident not as good as disposing afterwards: the lighter affects treatment time adversely, weight person jeopardizes patient's life.

Investigating from document, for solving the transfusion device problem of reporting to the police automatically, many innovations and patented technology have occurred, all is to adopt sensing technology, for example electromagnetism or light-inductive technology, flow or pulse conduction technology etc. basically.The problem of all have complex structure, using inconvenience, make difficulty, involve great expense.Its cost often is not complementary with " disposable use notion ", brings bigger financial burden to the patient.Therefore promote not open, can not generally use.

Notification number CN2430987y utility model patent has proposed a kind of " sound and light alarm disposable infusion set ", though can realize transfusion fault and transfusion termination reports to the police, but following defective is arranged: the one, the complex structure of float, the intermediary capillary tube of float is made difficulty; The 2nd, alarm and upper and lower contact and dropper combine as a whole, can not delamination, therefore still do not solve the high problem of cost.

Summary of the invention

The purpose of this utility model provides a kind of automatic alarming, disposable and uses transfusion device, accomplishes simple in structure, easy to use, cheap.

This utility model comprises maufee pot and pot lid, dropper, air inlet pipe are arranged on the pot lid, there is outlet the maufee pot lower end, improvements are in the maufee pot inner chamber float is arranged, be with slip cap on the dropper, between float and the slip cap dowel is arranged, also have the plunger type movable contact on the pot lid, the movable plunger lower end of this contact withstands on the slip cap; The micro integrated circuit alarm patches in plunger type movable contact stomidium, and the positive and negative electrode contact of matching with the alarm plug is arranged in the stomidium.The alarm model is the CH100 type, i.e. commonly used Music Clip on the greeting card, general only 15 millimeter of chip external diameter, a thickness 3-5 millimeter.

Movable plunger is positioned at plunger type movable contact bottom blind hole, and its top has conduction to touch circle, and there are two electric contacts that link to each other through lead with stomidium positive and negative electrode contact respectively at plunger type movable contact blind hole middle part.

Operation principle is as follows: during normal infusion, the liquid in the maufee pot floats float, and the slip cap that connects firmly by dowel and float is positioned at the dropper middle and upper part; Slip cap jack-up movable plunger makes conduction on the movable plunger touch circle and leaves two electric contacts in the intubate tube chamber, and alarm is not worked.When transfusion finishes, float falls towards the maufee pot bottom, drive under the slip cap and slide into dropper lower end (dropper lower edge external diameter is slightly larger than the slip cap internal diameter), meanwhile, movable plunger glides along the intubate inner chamber, and the conduction on it is touched circle and contacted the alarm circuit conducting with two electric contacts, send voice or optical signal, remind medical personnel in time to dispose.

Compared with the prior art, this utility model has following characteristics:

1, simple in structure, cheap, have and popularize and promotional value.

The micro integrated circuit alarm has relative independence, needs only during use their are inserted in plunger type movable contact stomidium.Therefore alarm is reusable.Therefore, this utility model is for the various infusion sets of introducing in the patent documentation with warning function, and is simple in structure, cheap, has and popularizes and promotional value.

2, sanitation and hygiene, safe and reliable

Because reusable alarm only inserts in the plunger type movable contact stomidium, directly do not contact with medicinal liquid, therefore can not pollute medicinal liquid.Float is small and exquisite transparent in addition, does not influence the observation to transfusion, and dropper tilts 30 ° the time, also can operate as normal, so sanitation and hygiene, safe and reliable.

3, easy to use, alleviate medical care, entourage's labor intensity and mental pressure

Need not change existing transfusion device rule of operation, medical personnel only need operational approach routinely to add medicinal liquid to transfusion device, air-out, after hanging, adjusting transfusion speed, alarm is inserted in the plunger type movable contact stomidium can relieved leaving away, and need not at every moment worry the transfusion termination and unwitting situation occurs.In a word, easy to use, alleviate medical care, entourage's labor intensity and mental pressure.

Description of drawings

Fig. 1 is that automatic alarming, disposable uses transfusion device structural representation (normal infusion state).

Fig. 2 is that section enlarged diagram (normal infusion state) is looked on a plunger type armature contact part left side.

The specific embodiment

This utility model comprises maufee pot 1 and pot lid 2, dropper 3, air inlet pipe 4 are arranged on the pot lid 2, there is outlet 5 the maufee pot lower end, difference is in maufee pot 1 inner chamber float 6 to be arranged, be with slip cap 8 on the dropper 3, between float 6 and the slip cap 8 dowel 7 is arranged, also has plunger type movable contact 9 on the pot lid 2, movable plunger 91 lower ends of this contact withstand on the slip cap 8, micro integrated circuit alarm 10 patches in plunger type movable contact 9 stomidiums, and the positive and negative electrode contact of matching with alarm 10 plugs is arranged in the stomidium; Movable plunger 91 is positioned at plunger type movable contact 9 bottom blind holes, and its top has conduction to touch circle 93, and there are two electric contacts 92 that link to each other through lead with stomidium positive and negative electrode contact respectively at plunger type movable contact 9 blind holes middle parts.
