Description

Medical electric transfusion speed counter

Technical field

This utility model relates to a kind of speed counter, particularly a kind of speed counter that is used for medical Transfusion device transfusion meter speed.

Background technology

Venous transfusion is the most frequently used treatment means of clinical medicine, and the regulation and control of transfusion speed are nurse's routine works, must make an inspection tour and check transfusion speed in every 30-60 minute in accordance with regulations.Used inspection metering method is artificial ocular estimate at present, while promptly the nurse sees that showing timing estimates the number of drops that counting drips from Murphy tube, thereby calculates transfusion speed (droplet/minute).The method working strength is big and degree of accuracy is poor, and patient that control is infused to needs such as children's and cardio-pulmonary function difference person have certain danger.

Summary of the invention

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of working strength little, counts fast degree of accuracy height, and is easy to use, the medical electric transfusion speed counter that safety is good.

Technical solution of the present utility model;

A kind of medical electric transfusion speed counter, it includes the speed counter box, this speed counter box is made of box body and lid, it is characterized in that in the box body and the corresponding inner surface of its lid be provided with transfusion device on the Murphy tube groove and the concave surface that match, and on the respective slot of box body, the lower end has the through hole that is communicated with and passes box body with groove, and lid and box body are tightly connected, a side position of respective slot is provided with light source in box body, and be provided with illuminator in the box body of same side position above light source of respective slot, in box body respective slot opposite side position and with box body in illuminator be provided with optical receiver with high position, the output of optical receiver connects timing displaing circuit.

This utility model be utilize photoelectricity transformation principle design liquid input speed in the infusion process is measured the electronic installation of demonstration, it has got rid of the error that anthropic factor causes in traditional artificial visually examine's metering, have suitable reliability and degree of accuracy, can reduce nurse's working strength greatly during use, improve work quality, safety is good, has broad application prospects.

The specific embodiment

As Fig. 1-6, this utility model includes the speed counter box, this speed counter box is made of box body 1 and lid 2, in the box body 1 and its lid 2 corresponding inner surfacies be provided with transfusion device on Murphy tube 3 groove 4 and the concave surface 5 that match, and on the respective slot 4 of box body 1, the lower end has the through hole 6 that is communicated with and passes box body 1 with groove 4, be used to put the tube for transfusion 7 that Murphy tube 3 two ends link to each other, after in Murphy tube 3 places box body 1 groove 4, on it, the tube for transfusion 7 of lower end just in time be positioned at box body 1 on, in the lower through-hole 6, and cover by lid 2, and lid 2 is tightly connected with box body 1, as being connected by grab switch 8, a side position of respective slot 4 is provided with light source 9 (this light source 9 can be to be made of laser tube 10 and battery 11 in box body 1, also by the lamp pearl, condenser lens and battery constitute), and be provided with illuminator 12 in the box body 1 of the same side position of respective slot 4 above light source 9, in box body 1 respective slot 4 opposite side positions and with box body 1 in illuminator 12 be provided with optical receiver 13 (as photoelectric receiving diode or photoelectrical coupler) with high position, the output of optical receiver 13 connects timing displaing circuit 14.Timing displaing circuit 14 is made of clock generator 15, timer 16, shaping circuit 17 and display 18.The output of optical receiver 13 connects the input of timer 16 through shaping circuit 17, and the output of timer 16 connects display 18, and display 18 is arranged on the surface of box body 1.

When this utility model uses, the Murphy tube on the transfusion device 3 is placed in the groove 4 of box body 1, and pushed down by the concave surface 5 of lid 2, the tube for transfusion 7 of Murphy tube 3 upper and lower ends is drawn from the upper and lower through hole 6 of box body 1.Then, energized switch 19, light source 9 is the emitting parallel light bundle, pass droplets fall pathway in the Murphy tube 3 through illuminator 12 reflections, throw and shine in offside optical receiver 13, the spherical droplets refraction changes the focus and the intensity of light beam in the droplets fall process, by its Strength Changes of optical receiver 13 perception and interval, produce the signal of telecommunication, this signal is delivered to timer 16 after shaping circuit 17 shapings, calculate droplets fall speed, send display 18 display result (droplet/minute), as if passing through to set button 20 setting droplet sizes is milliliter/droplet, then can show transfusion speed with " ml/min " or " milliliter/hour ".
