Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In consideration of the problem that the comprehensive monitoring is difficult to achieve by manually monitoring the transfusion condition of a patient by medical staff in the prior art, the embodiment of the utility model provides a disposable transfusion device with an empty transfusion prevention alarm device; the technology can be applied to medical places such as emergency venous transfusion, group venous transfusion, outpatient venous transfusion, operation venous transfusion and the like in wartime, and the embodiment of the utility model is described in detail below.
The first embodiment is as follows:
first, a disposable infusion set with an empty infusion prevention alarm device according to an embodiment of the present invention will be described with reference to fig. 1, 2 and 3.
A disposable infusion set with an anti-empty alarm device comprises: the infusion set comprises an infusion set body, a water level sensor 1, a singlechip 3 and an alarm 2. It should be noted that the infusion apparatus body is provided with a drip cup, that is, the liquid medicine is collected in the drip cup after dropping from the medicine bottle, the air is filtered and then enters the medicine bottle, and meanwhile, in order to effectively control the speed of injecting the liquid medicine into the human body, a flow rate regulator is arranged on the infusion apparatus body, specifically, below the drip cup.
In this embodiment, the above-mentioned level sensor is laminated on the inside wall of drip chamber to the liquid medicine volume in the accurate monitoring drip chamber, what of liquid medicine volume is obtained through the scale value of liquid medicine in the drip chamber promptly. Above-mentioned singlechip and alarm all set up on the lateral wall of drip chamber to, level sensor, singlechip and alarm are connected gradually and are carried out the transmission of signal of telecommunication, and is common, and level sensor adopts T51A level sensor, and the singlechip adopts ATmega16, and the alarm adopts hang ya YS-2000 audible-visual annunciator. It should be added here that, because there is no power supply on the infusion apparatus body, in order to make the water level sensor, the single chip microcomputer and the alarm device work normally, a lithium battery and the like can be correspondingly arranged on the outer side wall of the drip cup to supply the water level sensor, the single chip microcomputer and the alarm device to work. In the use process, the level sensor converts the collected liquid level value in the drip cup into a liquid level signal, then the singlechip compares whether the liquid level signal is smaller than a minimum liquid level limit value (the minimum liquid level limit value is a safe liquid medicine residual value which can be born by a patient), and when the liquid level signal is smaller than the minimum liquid level limit value, namely the liquid medicine in the drip cup is insufficient, the singlechip generates a current limiting signal, and then the alarm gives out sound and light alarm, such as sound or flash and the like after receiving the current limiting signal.
Preferably, the single chip microcomputer is ATmega 16. ATmega16 is a low power 8-bit CMOS microcontroller based on an enhanced AVR RISC architecture. In the processing process, the data throughput rate of the ATmega16 is as high as 1 MIPS/MHz, and the contradiction between the power consumption and the processing speed of the system can be effectively relieved. Compared with other types of single-chip microcomputers, the single-chip microcomputer has the advantages of low power consumption, high performance and long service life.

In the use process, the capacitance type water level sensor can be detected by being attached to the wall of a container (namely a drip cup), and the detectable objects comprise: various high viscosity, impure liquids, etc. However, the capacitive water level sensor requires a thick wall of a container to be attached, and when the wall of the container is too thick, the capacitive water level sensor cannot detect the wall. Compared with other types of water level sensors, the capacitance type water level sensor has higher measurement precision and strong stability.
In addition, still include the circlip in the above-mentioned disposable transfusion system who has anti-empty infusion alarm device, the circlip suit is in the liquid outlet department of drip chamber, and, circlip 5's diameter equals with the diameter of liquid outlet, and under the normal infusion condition, circlip bindes on the liquid outlet of drip chamber below, but does not restrict the flow of liquid medicine in the drip chamber.
In addition, the disposable infusion apparatus with the air transfusion prevention alarm device further comprises a stepping motor 4, wherein the input end of the stepping motor is connected with the single chip microcomputer, the output end of the stepping motor is connected with the elastic retainer ring, and the stepping motor is a two-phase direct current 28mm stepping motor. In the implementation process, when the liquid level signal is less than minimum liquid level limit value, it needs medical personnel in time to supervise to explain that current liquid medicine volume becomes less, it is concrete, send taut signal to step motor by the singlechip, thus, step motor receives after taut signal with the range upon range of winding of circlip in the liquid outlet department of dripping the kettle, step motor rotates under the taut signal effect of singlechip promptly, thereby drive circlip and twine in liquid outlet department, so that the inside wall of liquid outlet all pastes together, thereby the restriction remains liquid medicine continues to flow into in the human body.
In addition, in order to facilitate the medical staff to realize the supervision anywhere for the patient who infuses, the above-mentioned disposable infusion set with prevent empty alarm device still includes mobile terminal, and generally, above-mentioned mobile terminal can be smart mobile phone, panel computer, intelligent wearing equipment (for example, intelligent bracelet) etc. and mobile terminal all wears on patient's body usually. In the use, mobile terminal passes through the bluetooth with the singlechip and links to each other, and mobile terminal shakes after receiving above-mentioned current-limiting signal, also can send music, light etc. like this, no matter whether medical personnel are paying close attention to patient's infusion condition, all can in time go the liquid medicine condition of monitoring patient's transfusion system body under mobile terminal's warning.
The embodiment of the utility model provides a disposable transfusion system with prevent defeated empty alarm device includes: the infusion set comprises an infusion set body, a water level sensor, a single chip microcomputer and an alarm, wherein the infusion set body is provided with a drip cup, the water level sensor is attached to the inner side wall of the drip cup, the single chip microcomputer and the alarm are arranged on the outer side wall of the drip cup, the water level sensor, the single chip microcomputer and the alarm are sequentially connected, in the implementation process, the water level sensor converts the acquired liquid level value in the drip cup into a liquid level signal, and then the single chip microcomputer compares whether the liquid level signal is smaller than the lowest liquid level limit value or not, when the liquid level signal is less than the lowest liquid level limit value, the singlechip generates a current limiting signal, and the alarm gives out an acousto-optic alarm after receiving the current limiting signal, through the treatment process, the alarm can be sent out in time when the liquid level value in the drip cup is lower than the set value, thereby effectively reminding medical personnel to carry out real time monitoring to the infusion condition of the patient and avoiding the occurrence of the condition that air is injected into the human body.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
