Abstract
The utility model discloses a liquid-protection transfusion device capable of alarm, which belongs to the technical field of medical equipment, wherein a connecting clamp of an alarm meter is clamped on a transfusion needle of the transfusion device; a metal contact ring is inserted into the connecting clamp of the alarm meter and connected with the alarm meter by conducting wires; a thermosensitive probe tightly contacted with the transfusion needle is arranged in the connecting clamp of the alarm meter; the thermosensitive probe is also connected with the alarm meter; the lower end of the transfusion needle is provided with a bucket-shaped shape cavity, and a liquid-protection valve is arranged in the shape cavity. When accidents of transfusion appear or the transfusion is finished, the transfusion needle generates the change of temperature. The alarm meter gives an alarm because of the action of the thermosensitive probe. Because the alarm meter is connected with a caller on the bed head, nurses in a nursing chamber know that a patient on some sickbed generates transfusion accidents or finishes transfusion. The liquid-protection valve in the shape cavity automatically opens when transfusion is operated, and automatically closes when transfusion is finished; physic liquor is kept in a hose of the transfusion device arranged on the lower end of the liquid-protection valve, venous blood of patients can not flow backwards and nurses can reach late or early. The liquid-protection transfusion device capable of alarm has the advantages of omnidirectional alarm, convenient operation and high safety.
Description
Technical field
Guarantor's liquid transfusion device that this utility model can be reported to the police is the disposable infusion set that has improved, and belongs to technical field of medical instruments.
Background technology
The general disposable infusion set of present domestic use is by transfusion needle, air needle, flexible pipe, dropping funnel, connection is first-class forms.Patient tends to occur following situation in when transfusion: vein pierces through, has an injection that the position is swollen with, medicine liquid droplet gets and even do not drip very slowly; When needle tubing was obstructed, medicinal liquid can drip to such an extent that even do not drip very slowly again; When medicinal liquid dripped off, one did not note, venous blood flows backwards.Because these situations of existence need accompany the people to accompany and attend to during patient infusion, Here it is, and the plain edition disposable infusion set exists weak point.
Summary of the invention
Deficiency at above plain edition disposable infusion set existence, this utility model provide a kind of when medicine liquid droplet get very slow, stop dripping, dripping off all and can in time report to the police, and the nurse is under the situation that can not in time arrive, a kind of novel transfusion device that venous blood all can not flow backwards---the guarantor's liquid transfusion device that can report to the police.
For realizing above purpose, take following technical proposal.Do the alarm connection that can only clamp the disposable infusion set transfusion needle and press from both sides, alarm connects folder and connects alarm, is clipped on the transfusion needle of disposable infusion set, like this guarantor's liquid transfusion device of the meeting of composition warning.It is characterized in that: the alarm connection folder two ends that can be clipped on the transfusion needle are embedded with the Metal Contact ring, and the Metal Contact ring connects alarm with lead, between the Metal Contact ring of two ends thermosensitive probe is housed, and thermosensitive probe connects alarm with lead.Alarm connects when being clipped on the transfusion needle, the Metal Contact ring can closely be embraced transfusion needle, and excellent contact arranged, thermosensitive probe is close to transfusion needle and will be insulated with transfusion needle, set up one in the transfusion needle lower end and drip the bucket shape chamber, the shape intracavity adds one and protects the liquid valve, protects the proportion of the proportion of liquid valve raw material less than water.
Owing to adopt above-listed technical scheme, during patient infusion, alarm connected be clipped on the transfusion needle, the alarm energized, the transfusion needle between the two pairs of Metal Contact rings can produce slight fever.During normal infusion, the transfusion needle trace heats up.When medicine liquid droplet get very slow, stop dripping, when dripping off, because of the transfusion needle inner liquid medicine produces utmost point slow flow, does not flow or flow, the promptly rapid intensification of transfusion needle.When arriving the temperature of setting, because the effect and the conduction of thermosensitive probe, alarm is promptly reported to the police automatically.Reporting to the police simultaneously automatically is communicated with the nurse room, and the nurse room can learn which sick bed patient dropping liquid produces fault, or drips off and need change bottle or pull out pin.Drip bucket shape intracavity medicinal liquid because of the transfusion needle lower end and drip off, the guarantor's liquid valve in the dropping funnel is blocked the flexible pipe outlet, can keep medicinal liquid for a long time, and venous patient blood promptly can not flow backwards, and the nurse has busy, arrives later on, all problem can not take place.This transfusion device can reach comprehensive warning, and safe and reliable.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment one: Fig. 3 sets up one and drips bucket shape chamber (13) in transfusion needle (1) lower end, and the shape intracavity adds one and protects liquid valve (8), protects the important proportion less than water of raw material ratio of liquid valve (8).Make the alarm that can clamp transfusion needle (1) and connect folder (10) with injection molding shape such as folder shape, alarm connects folder (10) two ends and transfusion needle (1) contact position is embedded with two pairs of Metal Contact rings (11), and the internal diameter when two pairs of Metal Contact rings (11) merge equals the external diameter of transfusion needle (1).Alarm connects installs a thermosensitive probe (12) between the folder two pairs of Metal Contact rings in (10) two ends (11), two pairs of Metal Contact rings (11) use lead to be connected with alarm (9) respectively with thermosensitive probe (12).When alarm contact ring (10) was clipped on the transfusion needle (1), two pairs of Metal Contact rings (11) closely contacted with transfusion needle (1), and thermosensitive probe (12) also will closely contact with transfusion needle (1), and insulate with transfusion needle (1).During patient infusion, alarm (9) energized, alarm connects folder (10) and is clipped on the transfusion needle (1), and the transfusion needle (1) between two pairs of Metal Contact rings (11) promptly can generate heat by trace.During normal infusion, transfusion needle (1) inner liquid medicine proper flow, transfusion needle (1) promptly can heat up by trace, and when transfusion produced fault, medicine liquid droplet got too slowly or not and drips, and transfusion needle (1) inner liquid medicine flows and slowly or not flows, and promptly transfusion needle (1) heats up rapidly.Because the effect of thermosensitive probe (12), alarm (9) promptly can be reported to the police automatically.When following bucket shape chamber of transfusion needle (1) (13) when inner liquid medicine drips off, because of same principle, alarm (9) also can be reported to the police automatically.Because of alarm (9) connects patient's head of a bed beeper, alarm signal promptly can be delivered to nursing unit, and the nurse can know that promptly which ward medicinal liquid drips off or produce fault.Drip the interior liquid valve (8) of protecting in bucket shape chamber (13) because of transfusion needle (1) lower end and block bucket shape chamber (a 13) outlet, equal president's Kubo is held medicinal liquid in the transfusion device flexible pipe (4), and the nurse arrives sooner or later, and patient's venous blood can not flow backwards.This transfusion device can reach comprehensive warning, and safe and reliable.
Embodiment two: as Fig. 4, do not establish transfusion needle (1) lower end and drip bucket shape chamber (13), can directly be placed in the dropping funnel (3) protecting liquid valve (8), all the other structures are all the same with embodiment one with effect.
