Abstract

The utility model provides a precise transfusion device which comprises a Murphy drip tube and a transfusion tube. An infrared transmitting terminal and an infrared receiver are respectively arranged at the two sides of the Murphy drip tube, the infrared receiver is connected with a controller, a display screen and an adjusting button are arranged on the controller, a clamping ring is arranged on the transfusion tube, a sleeve is arranged at one side of the clamping ring, an electromagnetic device is arranged at the end of the sleeve, a spring is arranged in the sleeve, a push rod is arranged in the spring, one end of the push rod is connected with a clamping sheet, the other end of the push rod is connected with the electromagnetic device, and the electromagnetic device is connected with the controller by a lead wire. An alarm device is arranged on the controller. The precise transfusion device has the following advantages: the precise transfusion device can precisely control the transfusion speed, cannot be affected by external factors, can display the transfusion speed at any time, can be convenient for medical personnel to learn the transfusion condition, can send out alarm when medicine is run out of, can remind nurses to timely change the medicine or stop transfusing, can reduce times and time for medical personnel to visit wards, and can ensure safety transfusion.

Description

A kind of accurate transfusion device

Technical field

This utility model relates to a kind of medical Transfusion device, specifically a kind of accurate transfusion device.

Background technology

Some medicines needs strict control transfusion speed, and as nitrate esters, commonly used have nitric acid, a glycerol Dan Zuo (isosorbide mononitrate), often carries out drop with 8 droplets/minute, 10 droplets/minute, 15 droplets/minute speed under the general concentration.If excessive velocities, it is too much excessive to enter intravital drug dose in the unit interval, then can cause untoward reaction, as pulsatile headache, Blushing, blood pressure drops, heart rate quickening etc.; Also have quinolione class medicines such as ofloxacin, in the ordinary course of things, every input 0.2 gram should be to be no less than 1 hour speed dead point, and excessive velocities can cause the vasculitic pathological changes, entail dangers to life when serious.Traditional transfusion device can't be accomplished the accurate control to transfusion speed when transfusion speed is slow, make the patient infusion reaction occur easily.And the influence that the speed of traditional transfusion device when transfusion also can be received the factors such as variation of infusion bottle height, residual drug and patient self blood pressure is difficult for being maintained fixed speed.For the transfusion speed that guarantees each patient within safety speed, need the nursing staff often to make an inspection tour the ward usually, measure each patient's transfusion speed one by one, complex steps, medical personnel's amount of labour is big.

Summary of the invention

The purpose of this utility model provides a kind of accurate transfusion device, and it can accurately be infused according to predefined speed, and transfusion speed is not affected by other factors, and guarantees transfusion safety.Can show at any time and transfusion speed give the alarm when medicine is used up.

This utility model for achieving the above object, be achieved through the following technical solutions: comprise Murphy's burette and tube for transfusion, the Murphy's burette both sides are installed infrared emission end and infrared remote receiver respectively, infrared remote receiver is connected with controller, controller is provided with display screen and regulates button, clamp ring is installed on the tube for transfusion, clamp ring one side is provided with sleeve, barrel end is installed calutron, push rod is installed in the mounting spring in the sleeve, spring, and push rod one end is connected with intermediate plate, the other end of push rod is connected with calutron, and calutron is connected with controller by lead.Alarm device is installed on the controller.Tube for transfusion is provided with locating ring.

Advantage of the present utility model is: reasonable in design, can realize accurate control to transfusion speed, not influenced by extraneous factor, can show transfusion speed at any time, be convenient to medical personnel and grasp the transfusion situation, can send warning after medicine is used up, the prompting nurse in time changes medicine or stops transfusion, can reduce number of times and time that medical personnel make an inspection tour the ward, and guarantee transfusion safety.

Description of drawings

Fig. 1 is this utility model structural representation; Fig. 2 be among Fig. 1 A to the structure for amplifying sketch map; Fig. 3 be among Fig. 2 B to the structure for amplifying sketch map.

The specific embodiment

The primary structure of a kind of accurate transfusion device described in the utility model comprises Murphy's burette 1 and tube for transfusion 2, Murphy's burette 1 both sides are installed infrared emission end 3 and infrared remote receiver 4 respectively, infrared remote receiver 4 is connected with controller 5, controller 5 is provided with display screen 13 and regulates button 14, clamp ring 6 is installed on the tube for transfusion 2, clamp ring 6 one sides are provided with sleeve 7, the sleeve 7 terminal calutrons 11 of installing, mounting spring 8 in the sleeve 7, push rod 9 is installed in the spring 8, push rod 9 one ends are connected with intermediate plate 10, and the other end of push rod 9 is connected with calutron 11, and calutron 11 is connected with controller 5 by lead.Said structure can be realized goal of the invention of the present utility model, and its middle controller 5 can be controlled the open and close of calutron 11.

In order to remind the nurse in time to change after using up at medicine or to stop transfusion, alarm device 12 can be installed on controller 5 described in the utility model.

In order to prevent clamp ring 6, can on tube for transfusion 2 described in the utility model, locating ring 15 be set along tube for transfusion 2 landings.

This utility model in use, on controller 5, set the blanking time that each dropping liquid drips by medical personnel by regulating button 14, after finishing, setting starts infrared emission end 3, the infrared signal that infrared emission end 3 sends is received by infrared remote receiver 4, form the infrared monitoring district, controller 5 makes calutron 11 work, pulling push rod 9 simultaneously, make intermediate plate 10 unclamp tube for transfusion 2, the infusion pipeline conducting; When having drop to pass in the infrared monitoring district, infrared remote receiver 4 can send signal to controller 5, and controller 5 quits work calutron 11, and push rod 9 and intermediate plate 10 reset under the effect of spring, clamp tube for transfusion 2, closed infusion pipeline; Through after predefined blanking time, controller 5 makes calutron 11 task again, forms circulation.Current transfusion speed can be presented on the display screen 13, is convenient to medical personnel and grasps the transfusion situation.When medicine is used up, under the situation of infusion pipeline conducting, there is not drop to pass the infrared monitoring district, this moment, controller 5 meetings be reported to the police automatically by alarm device 12, and the prompting nurse in time changes medicine or stops transfusion.
