Abstract
The utility model relates to the field of the medical appliance, in particular to an infusion apparatus, which comprises an infusion dropper, a feed pipe connected with the dropper, and a discharging pipe. A floater is arranged in the cavity of the infusion dropper and positioned at the upper part of the discharging pipe, and connected with a guide rod, which is connected with an alarm device. The alarm device comprises a metal piece and an alarm circuit, wherein the metal piece is connected with the guide rod, and the alarm circuit consists of a metal block and a sounder. The metal piece moves up and down along the floater and the guide rod, when the floater closes the discharging pipe, the metal piece just contacts with the metal block, the density of the floater is less than that of the liquid medicine. The infusion apparatus of the utility model has the function of automatic closure and alarm when the infusion is completed, the structure is simple, and the use is convenient.
Description
Technical field
This utility model relates to the medical instrument field, relates in particular to a kind of transfusion device.
Background technology
At present, used transfusion device in medical treatment, its transfusion drip tube can only show the flow velocity of medicinal liquid, whether patient need pay close attention to medicinal liquid and flow when hanging point drips, need in time pull out syringe needle when having flowed, otherwise can cause blood to reflux, bring adverse consequences to the patient, and the sometimes busy staff of medical worker is not enough, does not in time find or have little time timely processing, has all brought very big trouble for doctor and patient.Though also have some medicinal liquids to beat the transfusion device of energy automatic-diversion closure in the market, do not have warning function.The patent No. be zl200520009699.4 patent disclosure a kind of transfusion device, possessed the function of automatic-diversion closure and warning, but its alarm device is a back dress when in use, pollutes to medicinal liquid easily, and uses inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of and possesses automatic-diversion closure, the prompt functions of being totally lost, and transfusion device easy to use.
In order to overcome the defective that exists in the background technology, this utility model adopts following technical scheme:
A kind of transfusion device, comprise transfusion drip tube, the feed tube that is connected with transfusion drip tube, drain pipe, the top that is positioned at drain pipe in the described transfusion drip tube cavity is provided with float, float is connected with guide rod, guide rod links to each other with alarm device, described alarm device comprises the sheet metal that links to each other with guide rod, the warning circuit that metal derby and tone generator are formed, sheet metal is along with float and guide rod move up and down, when float closes drain pipe, sheet metal just contacts with metal derby, and the density of described float is less than the density of medicinal liquid.When medicinal liquid was totally lost, float closed drain pipe, had effectively prevented the generation of blood backflow phenomenon; Simultaneously, the sheet metal that is connected with guide rod contacts with metal derby on the warning circuit, the warning circuit conducting, and tone generator begins sounding, reminds medical worker the patient here medicinal liquid of being totally lost.
The contact position of described guide rod and transfusion drip tube cavity is provided with sealing device.
Described warning circuit is provided with light-emitting device.Equipped light-emitting device, made the medical worker can find the patient of the medicinal liquid of being totally lost convenient, intuitively.
Described warning circuit is provided with switch.Convenient like this control alarm device.
The described fluid mouth of pipe can be arranged on a lot of positions, float below.
This utility model has adopted above-mentioned structure, and the function that makes described transfusion device possess automatic-diversion closure and be totally lost and report to the police is simple in structure, easy to use.
Description of drawings
Fig. 1: the structural representation of this utility model embodiment;
Fig. 2: the another kind of user mode sketch map of this utility model embodiment;
Fig. 3: this utility model embodiment 2 structural representations.
The specific embodiment
Below in conjunction with Figure of description, this utility model is described further by specific embodiment.
Embodiment 1: a kind of transfusion device of present embodiment, comprise transfusion drip tube 1, the feed tube 2 that is connected with transfusion drip tube 1, drain pipe 7, the top that is positioned at drain pipe 7 in described transfusion drip tube 1 cavity is provided with float 3, float 3 belows are connected with guide rod 4, guide rod 4 links to each other with alarm device, described alarm device comprises the sheet metal 6 that links to each other with guide rod 4, the warning circuit that metal derby 9 and tone generator 10 are formed, sheet metal 6 is along with float 3 and guide rod 4 move up and down, and the density of float 3 is less than the density of medicinal liquid 8.When float 3 closed drain pipe 7, sheet metal 6 just contacted with metal derby 9, the warning circuit conducting, and tone generator 10 sounds the alarm.Light emitting diode 12 can also be set on warning circuit, make it in chimes of doom, send light, make the medical worker can learn patient's position more intuitively.Switch 11 also is housed on the warning circuit controls warning circuit.Contact surface at guide rod 4 and minim pipette is provided with sealing ring 5.
Adopted this utility model transfusion device, float sinks to the drain pipe place when medicinal liquid has been beaten, has sealed drain pipe automatically, makes the medicinal liquid automatic-diversion closure.Stoped medicinal liquid to continue to flow, prevent the generation of the backflow phenomenon of transfusion person's blood, chimes of doom is sent in the warning circuit conducting simultaneously, remind patient and medical worker to handle the patient that light-emitting device can make the medical worker find medicinal liquid to be totally lost easily in numerous transfusion persons.This utility model is simple in structure, reasonable in design, has made things convenient for patient and medical worker.
Embodiment 2: in the present embodiment, alarm device is arranged on the top of minim pipette 1, is connected with guide rod 4 on the float 3, and guide rod 4 links to each other with alarm device, when medicinal liquid is full, metal derby 9 on sheet metal 6 and the alarm device breaks away from, and warning circuit is obstructed, when float 3 descends along with the decline of medicinal liquid when sealing drain pipe, sheet metal 6 contacts with metal derby 9, the warning circuit conducting begins to send chimes of doom prompting medical worker and comes to handle, and other structure is identical with embodiment 1.
The fluid mouth of pipe of the present utility model can also be arranged on a lot of places of float below, as long as float can be sealed drain pipe and just can realize effect described in the utility model when medicinal liquid has been beaten.
