The automatic drop controller is characterized in that a slotted hole corresponding to a catheter and a drop observing tube are arranged in the longitudinal middle portion of the controller, a transverse slide hole is arranged on the upper portion of the controller body, an open-close convex slide rod is mounted in the slide hole, a slotted hole corresponding to the catheter is arranged in the middle of the open-close convex slide rod, the convex end of the open-close convex slide rod is provided with a spring, a positioning baffle is hinged on a portion of the controller body corresponding to the spring, an electromagnet is arranged on a portion of the controller body corresponding to the positioning baffle, and the transmitter and the receiver are respectively arranged on corresponding portions on two sides of the slotted hole of the drop observing tube of the controller body. The automatic drop controller is compact and simple in structure, convenient in use and operation, low in cost and high in cost performance ratio and is labor-saving and time-saving.

Description

The drop automatic controller

Technical field

This utility model relates to a kind of injection control apparatus, particularly a kind of drop automatic controller.

Background technology

The disclosed application number of Chinese patent is 96120948.8 infusion monitor, and structure is numerous and diverse, complicated, and the cost height uses trouble, bothersome time-consuming.

Summary of the invention

At above problem, the purpose of this utility model provides a kind of compact conformation, drop automatic controller easy to use.

A kind of drop automatic controller, comprise the control body, power supply, control circuit, emitter and receptor, it is characterized in that: offer and conduit and the corresponding slotted eye of drop observing tube at control body longitudinal middle part, top at the control body offers horizontal slide opening, establish in the slide opening to be equipped with and open and close the convex slide bar, open and close on the convex slide bar middle part and offer and the corresponding slotted eye of conduit, establish on the nose of switching convex slide bar spring is housed, with the position of spring control corresponding body on be hinged with locating stop piece, with the position of locating stop piece control corresponding body on establish electric magnet be housed, emitter and receptor are established respectively on the corresponding site on the drop observing tube slotted eye both sides that are contained in the control body.

This utility model be utilize that control body longitudinal middle part offers with conduit and the corresponding slotted eye of drop observing tube controller can be inserted easily to fix on conduit and the drop observing tube, and main parts size is arranged on the control body, make very compactness of its structure.So, compact conformation, easy to use not only, and simple in structure, cost is low, use easy to operate, saving trouble saves time, and is a kind of drop automatic controller of cost performance.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model,

Fig. 2 be the A-A of Fig. 1 to cutaway view,

Fig. 3 be the B-B of Fig. 2 to cutaway view,

Fig. 4 is a kind of circuit frame principle figure of the present utility model.

Among the figure: control body 1, set screw 2, switching convex slide bar 3, conduit 4, spring 5, locating stop piece 6, emitter 7, drop observing tube 8, receptor 9, electric magnet 10, advance signal processor 11, pulse count signal device 12, alarm 13, time-pulse generator 14.

The specific embodiment

Describe in detail below in conjunction with drawings and Examples:

Fig. 1, Fig. 2 and Fig. 3 are a kind of drop automatic controllers of the present utility model, mainly comprise control body 1, power supply, control circuit, emitter 7 and receptor 9, it is characterized in that: the longitudinal middle part at control body 1 offers and conduit 4 and drop observing tube 8 corresponding slotted eyes, top at control body 1 offers horizontal slide opening, establish in the slide opening to be equipped with and open and close convex slide bar 3, open and close on convex slide bar 3 middle parts and offer and conduit 4 corresponding slotted eyes, establish on the nose of switching convex slide bar 3 spring 5 is housed, with the position of spring 5 control corresponding bodies 1 on be hinged with locating stop piece 6, with the position of locating stop piece 6 control corresponding bodies 1 on establish electric magnet 10 be housed, emitter 7 and receptor 9 are established respectively on the corresponding site on the drop observing tube slotted eye both sides that are contained in control body 1.

During use, push and put in place as long as will open and close convex slide bar 3, then longitudinal middle part is offered with conduit 4 and drop observing tube 8 corresponding slotted eye sleeves on conduit 4 and drop observing tube 8, this device just can be positioned on conduit 4 and the drop observing tube 8.When emitter 7 and the receptor 9 established on the drop observing tube slotted eye both sides corresponding site that is contained in control body 1, in the time of setting, do not detect dripping in the drop observing tube 8, alarm 13 is connected and is reported to the police.Connect electric magnet 10 simultaneously locating stop piece 6 is drawn to a side, if the spring 5 that is contained on the nose that opens and closes convex slide bar 3 stretches, drive to open and close convex slide bar 3 and reset, with intert on opening and closing convex slide bar 3 middle parts with conduit 4 corresponding slotted eyes in conduit 4 crimpings and closure catheter for closing 4.If continuously transfusion,, will open and close convex slide bar 3 again and push to put in place and get final product as long as replace the liquid bottle.

Fig. 4 is a kind of circuit structure block diagram of the present utility model.Speed with per minute number droplet in weep pipe drips with water, the path of intermittent disconnection light, the pulse signal that produces enters 11 shapings of advance signal processor, output in the pulse count signal device 12 after the shaping again, 12 li of pulse count signal devices with to carry out time ratio from time-pulse generator 14 right, when not having signal pulse, illustrate that water droplet does not drip when only time pulse in the several seconds, alarm 13 sends warning, and prompting tube for transfusion water droplet stops or finishing.

In order to report to the police, also to establish among the figure alarm 13 is housed.Alarm 13 can be light crossing-signal or buzzer, also can be provided with light crossing-signal and buzzer simultaneously.

In order to reduce cost, make emitter 7 and receptor 9 be convenient to be installed on the corresponding site on the drop observing tube slotted eye both sides of controlling body 1, the reflector 7 among the figure is a light emitting diode, receptor 9 is a photoelectric receiving tube.

Open and close convex slide bar 3 for the ease of regulating, make it be in best open and-shut mode, on the slide opening that opens and closes convex slide bar 3 afterbodys, also establish among the figure set screw 2 is housed.
