Abstract

The utility model discloses a vena infusion apparatus which comprises a Murphy dropper (2) connected with an infusion bottle (1), and is characterized in that the Murphy dropper (2) is internally provided with a pressure transducer (3), the signal output end of which is connected with a micro sounder (4). The vena infusion apparatus can remind a patient to pay attention to the condition of the remained liquid in the infusion bottle, thus enabling the patient or a doctor to take a farther medical treatment step so as to avoid unnecessary results and trouble.

Description

A kind of intravenous transfusion device
Technical field
This utility model relates to a kind of follow-on venous transfusion device, specifically relates to a kind of novel transfusion device that electronic technology such as micro pressure induction apparatus and generator is blended in existing infusion set.
Background technology
In hospital, we are through often seeing some patients when carrying out venous transfusion, because slight illness that disease produces or the discomfort on the health, and forgotten the amount of liquid medicine of being concerned about in the infusion bottle, thereby after medicinal liquid has flowed, also do not find situation, caused blood because the effect of pressure is flow backwards.So very dangerous, make the patient that accident on some unnecessary healths takes place easily.But up to the present, all there is so a kind of hidden danger on the existing transfusion apparatus, can not in time remind patient to be concerned about amount of liquid medicine in the bottle, thereby make the transfusion that patient can not be relieved or allow patient that the situation of backflow of blood takes place, thereby cause unnecessary trouble.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, provide a kind of can be when medicinal liquid will flow, assist by the certain amount of electrons engineering equipment, thereby when the medicinal liquid in the bottle will flow, can the patient who is infusing be given a warning the intravenous transfusion device of reminding patient to take further measures.
In order to solve the problems of the technologies described above, this utility model is to be achieved through the following technical solutions:
A kind of intravenous transfusion device, comprise link to each other with infusion bottle is it possible that the formula dropper it is characterized in that: is it possible that be provided with pressure transducer in the formula dropper, the signal output part of pressure transducer links to each other with minitype acoustic generator.
Described pressure transducer is a MEMS type pressure transducer
Compared with prior art, the beneficial effects of the utility model are:
Can remind patient to pay close attention to the residue situation of the liquid in the infusion bottle in time, thereby allow patient or doctor take further medical measure, and then avoid some unnecessary consequence and troubles.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
As shown in Figure 1, this utility model link to each other with infusion bottle 1 is it possible that be provided with pressure transducer 3 in the formula dropper, the signal output part of pressure transducer 3 links to each other with minitype acoustic generator 4.Detect whether soon transfusion by pressure transducer 3 and finish, and make minitype acoustic generator 4 in time send prompting sound.
Pressure transducer 3 in this utility model is a MEMS type pressure inductor, that it places the traditional infusion device is it possible that be used for the pressure that measurement of inductance dropper liquid produces on the formula dropper 2, when pressure is lower than a certain numerical value A, the MEMS pressure inductor will produce the signal of telecommunication, be transferred in the minitype acoustic generator 4, make generator 4 send the sound, thus arriving reminding patient's purpose.Silicon piezoresistance type pressure sensor in the MEMS pressure transducer is to adopt high-accuracy semiconductor resistor foil gauge to form resistance bridge as power electricity conversion measuring circuit, has higher certainty of measurement, lower power consumption, extremely low cost.The piezoresistive transducer of resistance bridge changes as no pressure, and it is output as zero, hardly power consumption.Thereby very using electricity wisely and higher practicality is arranged.On the other hand, because the more traditional pick off of MEMS type sensor bulk, volume is little, so its cost is low.Thereby it is a lot of that this utility model cost is reduced.
The undeclared part that relates in this utility model is same as the prior art or adopt prior art to be realized.

Claims (2)

1. intravenous transfusion device, comprise link to each other with infusion bottle (1) is it possible that formula dropper (2) it is characterized in that: is it possible that be provided with pressure transducer (3) in the formula dropper (2), the signal output part of pressure transducer (3) links to each other with minitype acoustic generator (4).
2. a kind of intravenous transfusion device according to claim 1 is characterized in that: described pressure transducer (3) is a MEMS type pressure transducer.
