Abstract
The utility model discloses a disposable transfusion set with the functions of liquid-breaking reminding and protecting. This utility model consists of a plug body, a dual-porosity syringe needle, a connecting pipe with an observing vesicle, a regulator, a needle and an alarm device. The plug body is a cylindrical bucket with a safe edge. A light sphere is arranged inside the bucket. A cubic concave pore is arranged on the safe edge, two induced needles are embedded inside the concave pore. The tip of the induced needle is inserted into the endoporus of plug body. The tail of need is bare in the concave pore and the needle tail can be used as a min-socket of the circuit in the alarm device. When people use the disposable transfusion set, the light sphere can close the transfusion pipe automatically when the transfusion of the liquid medicine in the bottle is finished to stop the medicine liquor of the transfusion pipe from entering the vein-vascular, which can prevent the blood from returning and at the same time, give alarm signal, and remind the medical staff to change the medicine in time. The utility model increases the safety factor of the medical care. Moreover, the utility model has the advantages of simple structure, convenient operation, safety and reliability.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of disposable transfusion device with disconnected liquid prompting and defencive function specifically.
Background technology
As everyone knows, connection tube and actuator that hospital's disposable transfusion device commonly used is observed bubble by plug, syringe needle, band are formed, and plug is a kind of syringe needle with diplopore, and being used for inserting infusion bottle derives medicinal liquid, then by connection tube and syringe needle input human body.This disposable transfusion device needs patient or entourage monitoring constantly and when medicinal liquid is totally lost, in time calls out what of infusion bottle inner liquid medicine medical personnel and change dressings when patient infusion.If heavier when patient's state of an illness, when needing long-time the transfusion, patient and entourage often occur tired and drowsy easily, one sleep soundly in the past as patient and entourage, when the bottle inner liquid medicine is used up, and medical personnel are not at one's side, are easy to occur danger such as vein blood back.
Summary of the invention
The purpose of this utility model provides a kind of disposable transfusion device with disconnected liquid prompting and defencive function; use this disposable transfusion device; when the bottle inner liquid medicine is totally lost; can automatically infusion pipeline be sealed; make the medicinal liquid in the infusion pipeline no longer continue the afferent veins blood vessel; prevent the vein blood back, send alarm signal simultaneously, remind medical personnel in time to change dressings.
The purpose of this utility model is achieved through the following technical solutions: connection tube, actuator and syringe needle that this disposable transfusion device is observed bubble by plug body, needles with two holes, band are formed, it is characterized in that: said plug body is the cylindrical dropping funnel of a band safe edge, the tail end of dropping funnel is made pyramid type and is connected with connection tube, the lightweight ball of a density less than water arranged in dropping funnel, and the circular cambered surface with lightweight ball equal diameters is made in the cross section of the connection tube that is connected with the dropping funnel tail end; Needles with two holes is being settled in the safe edge upper end, along a cube of type shrinkage pool is arranged on the diametric(al) of safe edge, in the shrinkage pool radial level embedding two inductive needles that keep at a certain distance away, the induction needle point inserts the plug body endoporus, backshank exposes in shrinkage pool the mini jack as alarm circuit.
Description of drawings
Fig. 1 has the disposable transfusion device structural representation of disconnected liquid prompting and defencive function for this utility model is a kind of;
Fig. 2 has the plug body enlarged drawing of the disposable transfusion device of disconnected liquid prompting and defencive function for this utility model is a kind of.
In Fig. 1, Fig. 2: 1, plug body, 2, needles with two holes, 3, safe edge, 4, inductive needle, 5, shrinkage pool, 6, the lightweight ball, 7, connection tube, 8, observe bubble, 9, actuator, 10, syringe needle, 11, alarm.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In Fig. 1 structural representation, plug body 1, needles with two holes 2, connection tube 7, observe bubble 8, actuator 9, syringe needle 10 all adopts medical material commonly used to make, needles with two holes 2, connection tube 7, observe bubble 8, actuator 9, syringe needle 10 adopts conventional structure, plug body 1 adopts the cylindrical dropping funnel structure of band safe edge 3,10 millimeters～15 millimeters of dropping funnel diameters, long 30 millimeters～60 millimeters, the tail end of cylindrical dropping funnel is made pyramid type and is connected with connection tube 7,18 millimeters～24 millimeters of safe edge 3 external diameters, 6 millimeters～10 millimeters of internal diameters, 8 millimeters～12 millimeters of thickness, along a length of side is arranged on the diametric(al) is 6 millimeters～8 millimeters cube type shrinkage pool 5, inductive needle 4 adopts rustless steel to make, backshank is column type, 0.8 millimeter～1.5 millimeters of diameters, long 7 millimeters～10 millimeters, 2 millimeters～3 millimeters at interval on two pins, needle point inserts the plug body endoporus from cube type shrinkage pool 5 side by side, backshank exposes in shrinkage pool 5, lightweight ball 6 adopts the structure of vacuolar membrane plastics ball outsourcing one deck thin rubber, 6 millimeters～10 millimeters of diameters, the circular cambered surface with lightweight ball 6 equal diameters is made in the cross section of the connection tube 7 that is connected with the dropping funnel tail end, lightweight ball 6 has higher quality of fit with the circular cambered surface in connection tube 7 cross sections, and said lightweight ball 6 also can adopt cork to make or other are lighter than the material of water.
In the present embodiment, alarm 10 is can be reusable, adopt the band trigger commonly used and the warning circuit structure of musical film, also can adopt the circuit structure of other types, is connected with inductive needle 4 in the shrinkage pool 5 by a microcard.Alarm 10 also can be connected with the alarm device on the sick bed, plays the effect of interlink warning.
In the use, under the normal infusion situation, be full of medicinal liquid in the dropping funnel and in the pipeline, lightweight ball 6 is suspended in dropping funnel top, and inductive needle 4 is immersed in the medicinal liquid, because liquid has electric conductivity, making between two inductive needles 4 has electric current to pass through, and the trigger of alarm 11 is in a kind of stable output state; When medicinal liquid was totally lost, liquid level descended in the dropping funnel, and lightweight ball 6 descends thereupon, when between the inductive needle 4 during no liquid, formed between the inductive needle 4 and opened circuit, and caused the trigger upset, and alarm 11 is in another duty, triggers the musical film pronunciation, and prompting the medical worker change dressings; Simultaneously, when lightweight ball 6 continues to drop to connection tube 7 arc circular cross-sections, the top atmospheric pressure and below under the vacuum action, lightweight ball 6 bottom cambered surfaces are tightly sealed connection tube 7 arc circular cross-sections, guarantee that the surplus liquid in the connection tube 7 no longer continues afferent veins.Like this, both played the effect that disconnected liquid is reminded, had the defencive function that prevents backflow of blood again, and increased medical safety, and had simple in structure, easy to operate, safe and reliable advantage.
